Iris yellow spot virus (IYSV; family Bunyaviridae, genus Tospovirus) is an economically important viral pathogen of onion vectored by onion thrips (Thrips tabaci Lindeman). Rapid spread of IYSV has occurred in the western United States and Georgia, with recent reports of IYSV from New York in the northeastern United States (1). In June and mid-July of 2007, symptomatic plants were found in Ontario, Canada in onions grown from sets in a home garden in Grey County (44°27′N, 80°53′W) and on a small commercial farm in Ottawa-Carleton County (45°14′N, 75°28′W), respectively. In the home garden, bleached, elongated lesions with tapered ends occurred on middle-aged leaves of 30% of 100 plants. By August 2007, 91% of these plants were symptomatic. In Ottawa-Carleton, two lesions with green centers and yellow borders occurred on a single leaf of a single plant in a field of 1,120 plants. Symptomatic leaf tissue tested positive for IYSV by IYSV-specific antiserum from Agdia Inc. (Elkhart, IN) in a double-antibody sandwich (DAS)-ELISA. These two isolated and remote finds of IYSV in Ontario prompted a survey in early August of 2007 of the Holland Marsh (44°5′N, 79°35′W), the largest onion-producing region in Ontario. Nine onion fields separated geographically across the Holland Marsh Region were scouted and one to three samples of symptomatic tissue per field were analyzed by DAS-ELISA. IYSV was confirmed in seven of nine (78%) fields surveyed and in 13 of 16 (81%) of the individual samples. A reverse transcription (RT)-PCR assay was used to verify the presence of IYSV in one new symptomatic tissue sample per field collected from three of the fields where IYSV was confirmed by ELISA. Primers specific to the small (S) RNA of IYSV (5′-TAA AAC AAA CAT TCA AAC AA-3′ and 5′-CTC TTA AAC ACA TTT AAC AAG CAC-3′) were used (2). The resulting 1.2-kb amplicon, which included the 772-bp nucleocapsid (N) gene was cloned and sequenced. Sequence analysis showed that the N gene of the Ontario isolate (GenBank Accession No. EU287943) shared 92 to 98% nucleotide sequence identity with known IYSV N gene sequences. The highest nucleotide sequence identity (98%) was with Genbank Accession Nos. DQ233475 and DQ233472. To our knowledge, this is the first report of IYSV infection of onion in Ontario and Canada. This finding confirms further spread of the virus within North America and the need for research to develop more effective management options to reduce the impact of IYSV on onion production. The finding of IYSV in remote and isolated locations where onions were grown from sets implies that the spread of IYSV via infected bulbs warrants further investigation as a potentially important route of distribution of the virus.

Poplar is popular among farmers and planted widely in the form of block and boundary systems. The preferences of farmers are shifting much more towards bund plantations due to their smaller yield reductions and can take up kharif and rabi crops till rotation. As for boundary plantations, farmers tend to grow trees in any direction without concern for yield reduction or profitability. Against this background, an experiment was designed by planting poplar at 2 m intervals in East–West (E–W) and North–South (N–S) directions during 2008 to determine the production potential and economic viability of boundary plantations and their effect on sorghum (Sorghum bicolor) and wheat (Triticum aestivum) crop rotations till harvesting of the trees. The experiment comprised three variables: stand age (years); four aspects (northern and southern E–W rows, eastern and western N–S rows; these four aspects are considered by dividing the tree lines); and six distances from tree the lines (0–3, 3–6, 6–9, 9–12, 12–15, 15–18 m and a control). A split-split plot design with three replicates was used. A significant reduction of fodder biomass of sorghum and wheat yield was observed up to 9 m distant from the tree line: the reduction was 10 to 60% for the kharif season and 7.2 to 29.5% for rabi crops from the second year to eight years after planting, respectively. Interestingly, the poplar boundary plantation had a favorable microclimatic effect from 9 to 15 m distance from the tree line, which increased crop yields compared with the control. The total dry wood production of poplar in the E–W direction (166.99 mg ha−1) was almost two times more than production for the N–S direction (82.62 mg ha−1) at 8 years of rotation. The economic analysis of this study concluded that an E–W boundary plantation of poplars exhibited the maximum net returns of INR 549,367 ha−1, a net present value of INR 222,951 ha−1, a BC ratio of 1:1.65, an IRR of 85% and an LEV of INR 1,220,337 ha−1. Therefore, it is concluded that the intercropping of a sorghum-wheat crop rotation in E–W boundary plantations was more beneficial for enhancing farm income over traditional agriculture in north India.

AbstractThe work performance of two teams of four donkeys (heavy, 680 kg and light, 460 kg) and one pair of Jersey crossbred oxen (646 kg) was compared when they ploughed 4 hi day on four types of soil (clay, redsoil, sandy soil and sandy clay) using two types of plough, a conventional ox plough (40 kg) and a lighter prototype, the ‘Walco’ plough (32 kg) on an experimental farm. Work parameters were also measured with farmers’ cattle and donkey teams ploughing on f arms in Matobo and Nkayi districts. Working speed, power and effective field capacity (ETC) were higher for the ox-team (1·03 m/s, 920 W and 14·5 h/ha for the conventional plough and 0·99 m/s, 745 W and 13·9 h/hafor the Walco plough) and the heavier donkey team (0·87 m/s, 689 W and 14·2 h/hafor the conventional plough and 0·87 m/s, 787 W and 17·3 h/hafor the Walco plough) than for the lighter donkey team (0·59 m/s, 461 W and 22·1 h/hafor the conventional plough and 0·64 m/s, 445 W and 23·4 h/hafor the Walco plough). Expressed as a proportion of live weight or metabolic live weight there were no significant differences in draught forces exerted between teams but power output per unit live weight was greater in the ox-team than in the light donkey team but similar to that in the heavy donkey team. The Walco plough required a lower force (742 N) to operate than the conventional plough (816 N) but apart from this did not have any marked advantages over the conventional plough. On-farm, team sizes of donkeys varied from three to seven animals (team weight 340 kg to 1007 kg) and cattle team sizes from two to four animals (team weights 558 to 1709 kg). Regardless of team number, the heavier teams tended to out-perform the lighter teams (speed range 0·63 to 1·08 m/s, power 395 to 1136 W, EFC 9·1 to 25 h/ha)) with one exception, a well trained team of two oxen (team weight 879 kg, speed 1·02 m/s, power 775 W, EFC 9·1 h/ha). Donkeys tended to plough at a slower pace than oxen, with a lower power output, although when weight differences between teams were equalized (four heavy donkeys compared with two oxen), then there was little to chose between the species. Results suggested that teams of three or more donkeys can effectively be used for ploughing on the soils tested. The results highlighted the importance that team live weight and training/experience have in determining work performance.

Finally here comes a volume modestly entitled Tolkien and the First World War. On the threshold of Middle-earth. This is the result of many years of study by the author, John Garth, who writes in the introduction: This biographical study was born from one observation: how strange that J.R.R. T o l k i e n b e g a n t o c r e a t e h i s m o n u m e n t a l m y t h o l o g y i n t h e m i d s t o f t h e F i r s t W o r l d W a r, [emphasis added — J.Z.L] that disappointing crisis that shaped the present day. This sentence may surprise the Polish reader, whose consciousness has shaped a completely different image of the First World War, as an event that may have been a crisis, but gave Poland the independence it had been dreaming of for over a hundred years. Meanwhile, for the generation to which Tolkien belongs, it was just that — a crisis. As Hermann Broch, who was slightly older than him, wrote about this war: “Goodbye Europe, beautiful tradition is over”. Garth shows how Tolkien contrasted his work with this perception of the experience of the Great War, a work that is a great mythical story about destruction but also about hope. At the same time, it is a tribute to the memory of the generation that died in the trenches of Flanders.

The present study was conducted during October 2014 to June 2015 in the farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur to find out the most effective management option (s) against brinjal shoot and fruit borer (BSFB) with 6 treatments namely, Beauveria bassiana, 1´109 CFU @ g l-1, Bioneem 0.3 EC (Azadirachtin) @ 1.5 ml l-1, Tracer 45 SC (Spinosad) @ 0.4 ml l-1, Vertimec 1.8 EC (Abamectin) @ 1.2 ml l-1 of water, Mechanical control (hand picking) with clean cultivation and untreated control. Results revealed that shoot infestation at pre-fruiting stage was the lowest in Bioneem 0.3 EC (4.34%) and at fruiting stage in Tracer 45 SC treated plot (7.75%) and the highest was in untreated control plot (17.94% at pre-fruiting stage and 39.46 at fruiting stage). The lowest fruit infestation by BSFB was obtained with Tracer 45 SC (8.16% n/n and 10.0% w/w) followed by B. bassiana, 1´109 CFU (23.23% n/n and 18.27% w/w) and the highest infestation was observed under untreated control plot (48.59% n/n and 32.09% w/w). Percent reduction of infested fruit by number (83.21%) and weight (68.84%) over untreated control was higher in Tracer 45 SC treated plot resulting significantly higher marketable yield. Therefore, the significant highest marketable yield (34.39 t ha-1) was harvested in the plot treated with Tracer 45 SC followed by 22.78 t ha-1 with B. bassiana, 1´109 CFU and 19.26 t ha-1 from Vertimec 1.8 EC treated plot. The highest benefit cost ratio of 3.05 was obtained from Tracer 45 SC followed by 2.93 in B. bassiana, 1´109 CFU and 2.89 with Vertimec 1.8 EC sprayed plot.Bangladesh J. Agril.

AbstractLimited nutrient availability is one of the major challenges in organic farming. Little is known about nutrient budgets of organic farms, the underlying factors or effects on soil fertility. We therefore assessed farm gate nutrient budgets for nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg) and sulfur (S) of 20 organic farms in Germany and analyzed their soil nutri-ent status. In average, the budgets showed a surplus of N (19 kg ha−1), K (5 kg ha−1), S (12 kg ha−1), and Mg (7 kg ha−1), and a deficit of P (−3 kg ha−1). There was, however, high variability between farms (e.g. standard deviation up to ± 36 kg N ha−1), which was mainly explained by different degrees of reliance on biological N fixation (BNF) as N source. When farms obtained more than 60% of their N input through BNF, they had deficits of P (mean −8 kg P ha−1) and K (mean −18 kg K ha−1). Nutrient status of most soils was within the ad-vised corridor, but for P, K and Mg, 10–15% of fields were lower and 45–63% were higher than advised. Extractable soil nutrient contents did not correlate with the nutrient budgets, inputs or outputs. Only extractable soil P increased with increasing P inputs and outputs. Fur-thermore, a decrease in extractable soil P was detected with a prolonged history of organic farming, indicating a risk of soil P mining in organic farming systems. In conclusion, the study revealed nutrient imbalances in organic farming and pointed to P and K scarcity as a major challenge for organic farms with high reliance on BNF in the long term.

The field experiments were conducted in rabi seasons of 2014-15 and 2015-16 at research farm, Ludhiana, Punjab. Wheat variety (WH 1105) was sown in two row directions viz, east-west (E-W) and north-south (N-S) with three row spacing as S1 (15 cm), S2 (22.5 cm) and S3 (30 cm), and two mulching levels viz., Mo (No mulch) and M1 (mulch at the rate of 5t ha-1). PAR interception, canopy temperature, soil temperature and soil moisture were recorded periodically during the crop season in all the treatments. The results revealed that the intercepted photosynthetically active radiation (PAR) was 4- 5 per cent higher in E-W than N-S row direction which contributed 1.67 q ha-1 higher grain yield. Better utilization of solar radiation was observed in 15.0 cm row spacing and the canopy temperature was 0.5°C higher in unmulched crop as compared to mulched crop during both years. Straw mulching @ 5t ha-1 improved soil moisture and regulated soil temperature. Mean soil temperature was higher (1.0 ºC) under mulched crop as compared to unmulched crop. The soil moisture was 4-5 per cent higher under mulched crop as compared to unmulched crop which ultimately resulted in higher soil temperature during early growth stages. Significantly higher grain yield was recorded in mulched crop as compared to unmulched.

Cattle behavior and grazing distribution is probably related to the available food, although it could also be influenced by the canopy shade, ambient temperature and access to water. The objective of this study was to evaluate the interaction among tree cover (TC) and cattle positions (CP) when searching for food and comfort areas, under warm and hot weather, in a silvopasture system. Analyses were conducted on Pajonales farm, located in the municipality of Ambalema (lat. 4° 45’ 25.9” N; 74° 52’ 20.8” W) in Colombia, from December 2009 to January 2010. The farm has an average elevation of 300 masl. Mean precipitation is 1270 mm.year-1, and temperatura 28°C. The pasture used for this study had an area of approximately 54 ha, with topography from flat to gently sloping. TC was determined from digital orthophotos QuickBird using ArcGIS® 9.1. The paddock was segmented into a 0.25 ha grid cell lattice and all sapling canopies within grid cells and animal movement were mapped.Six cows (3 Brahman and 3 F1, Brahman x Holstein) equipped with GPS-collars (Garmin eTrex-Vista) configured to record and store position, were tracked during 60 days at 5‐min intervals. Average values indicate that cows, generally, traveled greater distances in warm period (7.4 km) and 6.1 km in the hot period. Cows prefer areas with low TC (˂ 20%) and intermediate TC (20-40%); these areas had more biomass of fodder dry matter. The study is an important contribution to understanding the dynamics of animals in search for food under grazing conditions.

All-solid-state-batteries (ASSBs) have long promised to be the next-generation of high-performance energy storage devices, with a step-change in energy density, stability and cell safety touted as potential advantages compared to conventional Li-ion battery cells.[1] The development of fast lithium-ion conductors is key to realising commercially-viable ASSBs, however significant challenges remain with the leading candidate materials. Complex metal hydrides, in particular BH4 - derived materials, have gained recent attention due to their high ambient temperature lithium ionic conductivities and good stability with lithium metal.[2] Nitrogen-based complex hydrides, such as materials within the Li-N-H system, have largely been studied as solid-state hydrogen stores. However, a key characteristic that links the impressive properties of the Li-N-H system in this application is the high Frenkel defect-based Li-ion conductivity, which facilitates the formation of amide-imide and imide-nitride-hydride antifluorite structured solid solutions.[3,4] These solid solutions represent an opportunity through careful stoichiometry control to tailor the properties of a Li-N-H based material for application as a solid electrolyte. Careful characterisation using X-ray diffraction and Raman measurements have allowed us to evaluate the structure of the solid solutions between lithium imide (Li2NH), lithium amide (LiNH2) and lithium nitride hydride (Li4NH), all dominated by a disordered anti-fluorite phase. We demonstrate the ability to tailor the conductivity of these materials between an ionic insulator and a superionic conductor by simple stoichiometry control. Lithium imide, and stoichiometries close to this compound, in particular display favourable properties as solid electrolyte materials. We herein exhibit the first demonstration of a Li-N-H material in an ASSB, with the materials displaying high lithium ion conductivities, wide electrochemical stability windows and potential for further tuning for this application. Ultimately, these results identify Li-N-H based complex hydrides as an interesting avenue of research for solid electrolyte application that is yet to be fully explored. We hope this presentation will highlight these materials and spark further development such as has been seen for oxide and sulphide based fast-ion conductors. 1) Z. Zhang, Y. Shao, B. Lotsch, Y.

Abstract The aim of study was to investigate the effect of nutrient solution leakage during plant cultivation in greenhouse on soil pollution. Investigations were conducted in horticultural farms in the Wielkopolskie province (Greater Poland), specializing in soilless plant cultivation in greenhouse. In the first farm located on sandy soil tomato has been grown since its establishment (Object A). Prior to the beginning of crop culture soil samples were collected for analyses at every 0.2 m layer, to the depth of one meter. Successive samples were taken also in autumn after the completion of 1, 2, 3 and 7 culture cycles. For comparison, research was also conducted in a greenhouse located on loamy sand/sandy loam soil used for 8 years for tomato culture (Object B). In all these facilities plants in rockwool were grown and the fertigation in an open system was provided. Chemical analyzes showed the dynamics of soil properties changes and vertical distribution of cations and anions within the soil profile. Increased content of almost all nutrients and particularly of S-SO4, P, K, Zn, N-NH4, N-NO3 in the soil profile in object A and S-SO4, K, P, N-NO3 in the soli profile in object B were recorded. The results showed that the degradation rate of the soil environment as a result of open fertigation system application depends primarily on the duration of greenhouse operation. However, explicit changes in the chemical properties of soils were observed already after the first growth cycle. Smaller doses of fertilizers and water, and in consequence reduction of nutrients losses may be achieved by closed fertigation systems.

ABSTRACT Microirrigation associated with nitrogen (N) fertilization aims to meet the water and nutritional demands of cactus pear. The objective of this study was to evaluate the growth and yield of cactus pear (Opuntia ficus-indica) irrigated by microirrigation and fertilized with N. The experiment was conducted in the field at the Poço Redondo farm, Santa Luzia, PB, Brazil (6° 52’ 27’’ S and 36º 56’ 0’’ W and altitude of 299 m), between April and December 2017. The experimental design was in randomized blocks in a 5 x 2 factorial scheme, with five irrigation frequencies (7, 14, 21, 28 and 35 days) and two types of fertilization (soil fertilized with N and not fertilized) in the cultivar ‘Orelha de Elefante Mexicana’, with three replicates. Different irrigation frequencies promote reduction in green biomass yield and increase in the economic water productivity when using of the cladode for propagative material. Nitrogen fertilization increased growth, green biomass yield, water productivity and economic water productivity. The greatest economic return is obtained by producing cladodes marketed for propagative material. Reducing the frequency of irrigation promotes greater water saving, increasing the irrigated area and production by using less water at high frequency.

The most obvious use of uniformity trial data is to provide information on the most suitable size and shape of plots, in which the field was planted to a single variety and harvested as small plots. Indian mustard (Brassica juncea L.) cultivar RH-749 was grown using uniform crop improvement practices during rabi season of 2013-14 at Research Farm of Oilseed section, Department of Genetics and Plant Breeding, CCSHAU, Hisar, Haryana state, India, to estimate optimum plot size and shape using yield data of the 48 m × 48 m (2304 basic units) recorded separately from each basic unit of 1 m × 1 m. The variability among plots of different sizes and shapes was determined by calculating coefficient of variation. It was observed that the coefficient of variation decreases as the plot size increases in case of both the directions i.e., when plots were elongated in N-S direction (88 per cent decrease) or elongated in E-W direction (93 per cent decrease). Further it was observed that long and narrow plots elongated in E-W direction were more useful than the compact and square plots in controlling the soil heterogeneity. Based on the maximum curvature method the optimum plot size for yield trial was estimated to be 5 m2 with rectangular shape.

With the DFT theory at the forefront, non-PGM catalysts have begun to develop, and in much literature, results have shown that the performance of non-PGM catalysts is comparable to that of PGM catalysts. Jing et. al. synthesized Fe-Co dual sites on nitrogen-doped carbon for oxygen reduction reaction (ORR). (FeCo)/N-C had almost equal half-wave potential to commercial Pt/C.[1] Hanguang et. al. achieved high ORR-activated Fe-N-C catalysts by tuning the doped Fe content and active sites.[2] However, if both (FeCo)/N-C and Fe-N-C were applied to PEMFC, they were not comparable to PGM catalysts unlike in the results of the half-cell test. This discrepancy means that numerous factors should be considered and optimized in a practical system like a fuel cell. Besides, it is indicated that even if the DFT theory and deep-learning combine to suggest catalysts with high performance, it may not produce as much performance in the actual fuel cell system as expected. In this respect, the combination of fuel cell systems (not catalysts) and artificial intelligence (AI) seems more reasonable. Without human judgment or intervention, machine learning sets priorities between each index by learning from many databases. Herein, we newly developed an optimization model for alkaline liquid fuel cell (Hydrazine fuel cell) using gradient boosting algorithm (XGBoost) which is one of machine learning algorithms. We operated fuel cells in various conditions by changing humidity of cathode, back pressure of cathode, cell temperature, stoichiometric factor (air/fuel), and concentration of the fuel. And then, we categorized and classified with the specific algorithm. Finally, we re-organized and set as a function of weight which effects on fuel cell operation. We hope that these approach will help improve fuel cell performance by controlling a number of factors without human intervention. [1] J. Wang, Z. Huang, W. Liu, C. Chang, H. Tang, Z. Li, W. Chen, C.

Potatoes are a major crop in the Columbia Basin of Oregon and Washington, representing an annual farm gate value of almost $750 million. Zebra chip disease (ZC), a new and economically important disease of potato, was first reported in Oregon and Washington in 2011 (1). The disease is caused by the bacterium ‘Candidatus Liberibacter solanacearum’ (Lso, also referred to as ‘Ca. L. psyllaurous’), which is vectored by the potato psyllid (Bactericera cockerelli Sulc) (1,2). Identifying alternative hosts for Lso may facilitate management of ZC disease, which has increased potato production costs in the region. The perennial weed, bittersweet nightshade (Solanum dulcamara L.), is a year-round host of the potato psyllid (3) and is also a suspected host of Lso. However, little is known about the role of this weed in ZC epidemiology. Naturally occurring bittersweet nightshade plants (n = 21) were sampled at six different locations near Hermiston, Oregon, between May and October in 2012. These plants exhibited several symptoms associated with Lso, ranging from asymptomatic to slight purpling, chlorosis, or scorching of the foliage. However, S. dulcamara exhibits similar symptoms under a variety of environmental conditions (drought stress, etc.); therefore, it was difficult to identify potentially infected plants based solely on symptomology. Leaf and stem tissue (n = 21) was analyzed with high-fidelity PCR using species-specific primers for the 16S rDNA gene, CLipoF, and OI2c (2,4). Approximately 27.3% of the plants tested positive for Lso using these primers, including plants from the following locations on 16 April, 16 May, and 24 May, respectively: Hat Rock, OR (45°55.033′ N, 119°10.495′ W), Irrigon, OR (45°54.560′ N, 119°24.857′ W), and Stanfield, OR (45°46.971′ N, 119°13.203′ W). Three plants were selected for further PCR analysis with primers for the outer membrane protein gene, 1482f and 2086r (1). Amplicons obtained with both sets of PCR primers were directly sequenced. A BLAST analysis showed that the 16S rDNA gene sequence (993 to 1,000 bp) shared 99 to 100% identity with several Lso accessions, including JN848751.1 (from Washington) and JN848753.1 (from Oregon). Likewise, the outer membrane protein gene sequence (600 to 601 bp) shared 99 to 100% identity with ‘Ca. L. solanacearum’ accession KC768330.1 (from Honduras). All six sequences were deposited in GenBank (Accession Nos. KJ854199 to KJ854204). According to these findings, bittersweet nightshade may be an important annual source of Lso in the region, particularly since it serves as a host for the potato psyllid. Potato psyllids were also detected at two of the locations with infected S. dulcamara: Irrigon, OR, and Stanfield, OR. A subsample of the psyllids collected in 2012 were analyzed with PCR and Lso was detected in a sample from Stanfield, OR (5). Identifying perennial hosts of Lso promotes a better understanding of both ZC disease epidemiology and management. To our knowledge, this is the first report of Lso causing natural infections in S. dulcamara in the United States. References: (1) J. M. Crosslin et al. Plant Dis. 96:452, 2012. (2) S.

The purpose of this study was to evaluate the integrity of two forest fragments in Rio Negro Pantanal sub-region, using coleopterans as environmental indicators. The study was carried out at Santa Emilia Farm in the Rio Negro sub-region, municipality of Aquidauana, Mato Grosso do Sul (19º 30' 18'' S and 55° 36' 45'' W). Two sites were selected, locally denominated as "cordilheiras" (narrow and elongated strands of elevated soil), one with low degree of anthropic disturbance (CL) and the other, currently undergoing restoration process (TD). The sampling sites were determined using a GPS device. Ten pit-fall traps containing water and detergent were used for the specimens sampling, which were screened and identified. Abundance, richness, diversity and similarity were determined. Abundance was higher for CL (n = 277) than for TD (n = 251). The same was observed for the diversity indices, CL showed H' = 2.83 bit.individual-1 and TD = 2.48 bit.individual-1, confirming the interferences made for abundance. Specimens of ten families were captured in CL area and seven families in TD area, indicating higher richness in CL, when compared to TD. The linear correlation coefficient (p > 0.05) indicates that both areas are significantly different, showing similarity value of 66.7%. The data show that the structure and disturbance degree in the environment integrity influence the composition of beetles fauna, causing the increase of abundance, richness and diversity in anthropogenic environments undergoing the early stage of regeneration.

The age period of 0-8 years is the most important moment for every human being to develop all the developmental features supported by parents at home and teachers / tutors at the Early Childhood Education Institute (ECE). In parenting, six main aspects must be known and applied by each parent. Lack of education, nutritional knowledge, care and care, and aspects of clean-living habits in the family can have an impact on children's growth and development processes. This study aims to develop a module 6 aspects of child development for parental guidance. This study uses a research and development approach to test the effectiveness of the posttest design. Respondents in this study are parents who have children up to 5 years and early childhood educators. The findings show that from these six main aspects, it seems that parents and ECE tutors do not yet understand the ECE concept. In another perspective, there is still a lack of knowledge about these 6 main aspects which require training and parenting modules to develop the 6 aspects of child development.

Background Homeopathy has been widely applied in freshwater species but rarely in marine fish. Farm stress destabilises host–pathogen equilibrium, favouring parasites and disease. Coccidian endoparasites cause intestinal infections and cell degeneration. Materials and Methods Naturally parasite-infested juvenile snapper Lutjanus guttatus (n = 430; weight 1.9 ± 0.01 g; length 4.9 ± 0.03 cm) specimens were distributed in group sizes of 43, in 10 fiberglass tanks (100 L) with aeration and continuous water change. Five groups in duplicate were assessed: Passival (PaV); Passival and Phosphoricum acid Similia (PaV–PhA); Passival and Silicea terra Similia (PaV–SiT); Endecto and Infecçoes (End–Inf) and a control (Ethanol) for 45 days. Feed was sprinkled with treatment (5% v/w) and dried to avoid ethanol side-effects. Statistical results were expressed as mean ± standard error of the mean. Results Intestinal coccidia were recorded histopathologically, with the least incidence attained at T45 with End–Inf treatment (p < 0.001), coinciding with the highest lymphocyte (p = 0.015) count. Fish treated with PaV–PhA recorded a higher percentage of neutrophils (p = 0.015), and those treated with PaV–PhA, PaV–SiT and End–Inf revealed a decrease in lesions, degree of alteration and change in intestine and stomach tissues (p < 0.05). The number of mucous cells in gills was greater (p < 0.001) for End–Inf (43 ± 0.58), PaV–SiT (40 ± 2.89) and PaV–PhA (39 ± 3.46) as compared respectively with T0 and control (19 ± 0.58 and 28 ± 2.31). PaV and PaV–SiT increased carbohydrate reserves in liver (28.4 ± 1.39% and 22.4 ± 0.12%, respectively) compared with T0 and control (3.4 ± 0.32 and 5.6 ± 0.66%). The highest survival rate was 97.7 ± 0.16% in fish treated with PaV and End–Inf. Conclusion Homeopathic treatments had a positive effect on fish health. Besides the accumulation of metabolic reserves in the liver, homeopathic treatment was associated with mucin increase in gills as well as raised production of lymphocytes and neutrophils in blood, which could act as macrophages against intestinal coccidia.

Abstract The aim of this research was to evaluate changes in soil quality associated with the tillage system applied with chosen parameters of soil biological properties. The long-term field experiments were located at a private farm in Rogów (Zamooeć region, E Poland) on a silt soil and at the Experimental Station in Laskowice (Wrocław region, S-W Poland) on a sandy loam soil. Soil samples were collected from 0-15 and 15-30 cm layers. Winter wheat was grown under traditional, reduced and no-tillage systems. The analyses included estimations of microbial biomass C and N content, microbial respiration rate, activity of dehydrogenase and arylsulfatase, and fluorescein diacetate hydrolysis. After eight years the effects of tillage on both soils were clearly noticed. In general, the less disturbing tillage systems enhanced the increase of soil biological activity by 15-40%, on average, than conventional tillage system. The significant correlations between microbial biomass, and/or enzyme activities with total organic C content indicate that concentration of organic C in soil environment plays an extremely important role in enhancing the stabilization and activity of soil microorganisms, and protection of an extracellular enzymes. The studied parameters of soil biological activity showed their sensitivity to tillage applied and may be considered as an useful indicators of soil quality in monitoring all conditions alter soil environment.

The aim of this study was to estimate the optimum block size with the shape for field research experiments. A uniform crop of Indian mustard (Brassica juncea L.) variety RH-749 was raised during 2013-14 rabi season over an area of 48m Ã— 48m (2304 basic units) at Research Farm of Oilseed section, Department of Genetics and Plant Breeding, CCSHAU, Hisar, Haryana, India. The harvesting of crop was done in small units each of size lm Ã— lm (1m2). The blocks of sizes 4, 6, 8, 12 and 24 plots with various shapes, for different plot sizes were considered. The coefficient of variation (CV) decreased from 10.66 to 3.89 with the increase in block size from 4 to 24 , indicating that as the block size increased, homogeneity within the block also increases and the blocks elongated in E-W direction were more effective in reducing error variation than those elongated in N-S direction. It was also observed that C.V. without blocking (20.04) was much higher in comparison with the C.V. with blocking (3.89), thus indicating that blocking was beneficial in reducing error variation. The 24 plot blocks were found to be most efficient with 12m Ã— 2m block shape. Rectangular blocks are also advisable either when the experimenter does not have any idea about the fertility pattern of the experimental area or when border effects are large.

Iris yellow spot virus (IYSV; genus Tospovirus; family Bunyaviridae) is an economically important pathogen of onion. It is vectored by onion thrips (Thrips tabaci Lindeman) and causes widespread disease of onion in all major onion growing states in the western United States (1). In the eastern United States, IYSV was first reported in Georgia in 2004 (4) and then in New York in 2006 (2). In mid-July of 2010, symptomatic onion (Allium cepa) plants (cv. Candy) were found in New Holland, Pennsylvania, in Lancaster County on a small, diversified commercial farm (40.06°N, 76.06°W). Bleached, elongated lesions with tapered ends occurred on middle-aged leaves on approximately 30% of the 13,760 plants in an area approximately one tenth of an acre. Leaf tissue from five symptomatic plants tested positive for IYSV in a double-antibody sandwich (DAS)-ELISA with IYSV-specific serological reagents from Agdia Inc. (Elkhart, IN). A reverse transcription (RT)-PCR assay was used to verify the presence of IYSV in a subset of symptomatic leaf samples that reacted to IYSV antibodies in DAS-ELISA. Primers specific to the nucleocapsid (N) gene of IYSV (5′-ACTCACCAATGTCTTCAAC-3′ and 5′-GGCTTCCTCTGGTAAGTGC-3′) were used to characterize a 402-bp fragment (3). The resulting amplicons were ligated in TOPO TA cloning vector (Invitrogen, Carlsbad, CA) and two clones of each isolate were sequenced in both directions. Sequence analysis showed a consensus sequence for the partial N gene of the five IYSV isolates from Pennsylvania (GenBank Accession No. JQ952568) and an 87 to 100% nucleotide sequence identity with other IYSV N gene sequences that are available in GenBank. The highest nucleotide sequence identity (100%) was with an IYSV isolate from Texas (GenBank Accession No. DQ658242) and the lowest was with an isolate from India (GenBank Accession No. EU310291). To our knowledge, this is the first report of IYSV infection of onion in Pennsylvania. This finding confirms further spread of the virus within North America. Further study is warranted to determine the impact of IYSV on the Pennsylvania onion industry and to determine viable management strategies, if necessary. References: (1) D. H. Gent et al.

Multiple mitotic kinesins and microtubule-associated proteins (MAPs) act in concert to direct cytokinesis (Glotzer, M. 2005. Science. 307:1735–1739). In anaphase cells, many of these proteins associate with an antiparallel array of microtubules termed the central spindle. The MAP and microtubule-bundling protein PRC1 (protein-regulating cytokinesis 1) is one of the key molecules required for the integrity of this structure (Jiang, W., G. Jimenez, N.J. Wells, T.J. Hope, G.M. Wahl, T. Hunter, and R. Fukunaga. 1998. Mol. Cell. 2:877–885; Mollinari, C., J.P. Kleman, W. Jiang, G. Schoehn, T. Hunter, and R.L. Margolis. 2002. J. Cell Biol. 157:1175–1186). In this study, we identify an interaction between endogenous PRC1 and the previously uncharacterized kinesin KIF14 as well as other mitotic kinesins (MKlp1/CHO1, MKlp2, and KIF4) with known functions in cytokinesis (Hill, E., M. Clarke, and F.A. Barr. 2000. EMBO J. 19:5711–5719; Matuliene, J., and R. Kuriyama. 2002. Mol. Biol. Cell. 13:1832–1845; Kurasawa, Y., W.C. Earnshaw, Y. Mochizuki, N. Dohmae, and K. Todokoro. 2004. EMBO J. 23:3237–3248). We find that KIF14 targets to the central spindle via its interaction with PRC1 and has an essential function in cytokinesis. In KIF14-depleted cells, citron kinase but not other components of the central spindle and cleavage furrow fail to localize. Furthermore, the localization of KIF14 and citron kinase to the central spindle and midbody is codependent, and they form a complex depending on the activation state of citron kinase. Contrary to a previous study (Di Cunto, F., S. Imarisio, E. Hirsch, V. Broccoli, A. Bulfone, A. Migheli, C. Atzori, E. Turco, R. Triolo, G.P. Dotto, et al. 2000. Neuron. 28:115–127), we find a general requirement for citron kinase in human cell division. Together, these findings identify a novel pathway required for efficient cytokinesis.

N . F. S. Grundtvig: View of the History of Poetry and Bernhard Severin Ingemann. MS in the Grundtvig Archives, Fasc. 179, 1, from 1822.Edited by Flemming Lundgreen-Nielsen. Museum Tusculanum, Copenhagen 1985.Reviewed by Gustav AlbeckThis is a manuscript that deserves to have been edited and published before now. The poet’s son, Svend Grundtvig, did the preparatory work but never got his edition published. The cover of the present edition depicts W. E. Parry’s two ships in the polar darkness during his attempt to discover the North-West Passage in 1819-20. The reviewer informs us that in the manuscript Grundtvig describes the development of poetry as an unbroken chain of voyages of discovery, in which the contemporary, unsolved problem of the North-West Passage appears as a recurrent metaphor in various contexts.The editor, the excellent Grundtvig scholar, Dr. Lundgreen-Nielsen, has supplied a compact and scholarly preface and a commentary that is almost too thorough. Yet it must be admitted that the text requires both empathy and notes. It is not easy tofollow the poet’s image-filled presentation. It has previously been employed by Fr. R.nning in a little piece on Grundtvig as an aesthete (1883) and in the anthology Towards a Characterisation of N . F. S. Grundtvig (1915). Dr AlfHenriques has advanced some important reflections on this in his doctorate Shakespeare and Denmark (1941), as has Dr Helge Toldberg in his doctorate Grundtvig’s Symbolism (1950). Most recently Helge Grell has made use of some of the views expressed therein in his book The Creative Word and the Figurative Word (1980).The text is an interesting link in the development of Grundtvig’s view of the nature and mission of poetry. It does not tell us much about the poet Ingemann, even though it is evident from the manuscript that his name was the original title; comment on him fills a mere eight of the manuscript’s forty pages. In a kind of epilogue Grundtvig himself recognises that the essay assumes a knowledge of “the poetry and achievements of the strangest peoples” and the ability to “gather what they know”, an art which is far from common. But it is the hope of both editor and reviewer that it will find a varied group of readers.The introduction offers an outline of Grundtvig as an aesthete, a full and stimulating contribution to a work that is still waiting to be written. It does demand, however, “a systematic publication of the posthumous papers concerned with aesthetic matters,” and “a special Grundtvig dictionary”: two wishes that the reviewer shares with the editor. But there are other areas where Professor Albeck disagrees with, and is critical of, Dr Lundgreen-Nielsen.For example, the reviewer does not believe the essays were written with foreigners in mind. In his epilogue Grundtvig writes that here he “had strangers in mind” (nb. the Danish word fremmed means both ‘strange’ and ‘foreign’). The question is, What does he mean by ‘strangers’? Both the content and the language point to him addressing a domestic audience, but one that is distanced from him. He presupposes an acquaintance with the Danish language and history as well as a love of Denmark that could scarcely be expected of any but his compatriots. It is possible that originally he did have a foreign audience in mind, but changes his direction. Professor Albeck imagines that Grundtvig has originally thought of a Danish periodical (or possibly the Danish newspaper LatestPictures of Copenhagen, where he has found one of the essay’s main images, the North-West Passage). The title suggests that Grundtvig’s primary interest has been to introduce his poet-friend Ingemann to a wider public, but that the introduction to this has swollen out of all proportion into a strongly subjective survey of the history of poetry in the world.

The G143A mutation in cytb (cytochrome b gene) is associated with high levels of resistance to quinone outside inhibitor (QoI or strobilurin) fungicides that disrupt electron transport during cellular respiration (1). The G143A mutation in Zymoseptoria tritici (synonyms: Mycosphaerella graminicola and Septoria tritici), the causal agent of septoria tritici blotch of wheat (Triticum aestivum), was first reported in Europe in 2001 (1). Although Z. tritici has a global distribution (3), G143A mutants of Z. tritici have not been reported outside of Europe. We used PCR-RFLP (4) to estimate the frequencies of G143A mutants in Z. tritici populations at two locations in the Willamette Valley of western Oregon: the Hyslop Crop Science Field Research Laboratory (Hyslop Farm, HF), Benton County (44°37′52.85″ N, 123°11′55.19″ W) and research plots planted in a commercial wheat field in Washington County (45°33′58.53″ N, 123°00′11.78″ W) (North Valley Farm, NVF). Isolates originated from flag leaf collections from two cultivars (‘Bobtail’ and ‘Tubbs 06’) made in April and June of 2012 from plants in a replicated fungicide-treatment experiment, with isolates collected from both sprayed and unsprayed plots. Sixteen of the 169 isolates (9.5%) from HF possessed the G143A mutation (7 of 132 isolates from plots not receiving a QoI fungicide and 9 of 37 isolates collected from plots receiving two applications of the QoI azoxystrobin). One hundred forty six of the 175 isolates (83.4%) from NVF were G143A mutants (101 of 129 isolates from plots receiving no QoI fungicide and 45 of 46 isolates from plots receiving two applications of azoxystrobin). Results of phenotypic assays of a subset of 10 isolates from each location (5 mutants, 5 wild types from each location; 20 isolates altogether) supported a high level of resistance to azoxystrobin only in the G143A mutants. All 10 G143A mutants developed colonies after 8 days of growth on YMA plates amended with SHAM (2) and 1 ppm or 10 ppm azoxystrobin, with nine and eight G143A mutant isolates developing colonies on plates amended with 1 ppm and 10 ppm azoxystrobin, respectively. None of the wild-type isolates developed colonies on plates amended with SHAM and 1 ppm azoxystrobin, nor on plates amended with SHAM and 10 ppm azoxystrobin. All 20 isolates developed colonies on YMA plates lacking azoxystrobin, and treatments produced identical results across three replicates. These results are consistent with findings of higher levels of azoxystrobin resistance in G143A mutants compared to wild types in European populations (1). Isolates from HF and NVF differ in their previous exposure to QoI fungicides. The majority of the wheat area at HF is planted to breeding plots that are not sprayed with fungicide. Plots at NVF were planted in a commercial wheat field in a county where most wheat fields were treated with two to three applications of strobilurins each year over the past 4 years. Future monitoring for G143A mutants of Z. tritici throughout its range in North America will be necessary to assess whether strobilurin resistance will spread via wind-dispersal of ascospores or emerge de novo in treated fields. In Europe, stobilurins were first applied to wheat in 1996. G143A mutants of Z. tritici emerged de novo several times (4) and were widespread by 2007. References: (1) B. A. Fraaje et al.

A two-component injectable hydrogel was suitably prepared for the encapsulation and prolonged release of tilorone which is an antimuscular atrophy drug. The rapid (7–45 s, depending on the polymer concentration) in situ solidifications of the hydrogel were evoked by the evolving Schiff-base bonds between the aldehyde groups of modified PVA (4-formyl benzoate PVA, PVA-CHO, 5.9 mol% functionalization degree) and the amino groups of 3-mercaptopropionate chitosan (CHIT-SH). The successful modification of the initial polymers was confirmed by both FTIR and NMR measurements; moreover, a new peak appeared in the FTIR spectrum of the 10% w/v PVA-CHO/CHIT-SH hydrogel at 1647 cm−1, indicating the formation of a Schiff base (–CH=N–) and confirming the interaction between the NH2 groups of CHIT–SH and the CHO groups of PVA-CHO for the formation of the dynamic hydrogel. The reaction between the NH2 and CHO groups of the modified biopolymers resulted in a significant increase in the hydrogel’s viscosity which was more than one thousand times greater (9800 mPa·s) than that of the used polymer solutions, which have a viscosity of only 4.6 and 5.8 mPa·s, respectively. Furthermore, the initial chitosan was modified with mercaptopropionic acid (thiol content = 201.85 ± 12 µmol/g) to increase the mucoadhesive properties of the hydrogel. The thiolated chitosan showed a significant increase (~600 mN/mm) in adhesion to the pig intestinal membrane compared to the initial one (~300 mN/mm). The in vitro release of tilorone from the hydrogel was controlled with the crosslinking density/concentration of the hydrogel; the 10% w/v PVA-CHO/CHIT-SH hydrogel had the slowest releasing (21.7 h−1/2) rate, while the 2% w/v PVA-CHO/CHIT-SH hydrogel had the fastest releasing rate (34.6 h−1/2). Due to the characteristics of these hydrogels, their future uses include tissue regeneration scaffolds, wound dressings for skin injuries, and injectable or in situ forming drug delivery systems. Eventually, we hope that the developed hydrogel will be useful in the local treatment of muscle atrophy, such as laryngotracheal atrophy.

A survey of vine decline diseases of melons (Cucumis melo L.) was conducted on three geographically separate farms (12 fields) in the area of San Lorenzo, Honduras, during the spring of 1996. Symptoms were typical of the vine declines in that the leaves began yellowing and collapsing in the crown just prior to harvest and the decline radiated outward. Crown lesions, typical of many of the vine declines, were observed infrequently. Most plants exhibited no crown lesion. Roots exhibited brown lesions and root corking, and were generally lacking root hairs, although the roots were not macerated. Fruit were small sized, low in sugars, and sunburned. Isolations were made from the crown area, primary root, and secondary roots of affected plants by excising 3- to 5-mm pieces and surface sterilizing for 30 to 60 s with 0.5% sodium hypochlorite. Four tissue pieces from each plant part were placed on 2.0% water agar plus 0.1 g of streptomycin sulfate per liter and their identity maintained. Plates were examined for fungal growth daily for 5 days and hyphal tips from all colonies were transferred to potato dextrose agar and Synthetischer nährstoffärmer agar (2) to allow for sporulation. Rhizoctonia solani Kühn was the predominant fungus isolated from affected plants in several fields, with an incidence as high as 75%. A Pythium sp. was isolated from primary and secondary roots of 50% of the plants on the Santa Rosa farm. Vines exhibiting tan to light brown crown lesions either on one side of the vine or encompassing the crown, but without gumming, always produced colonies of Fusarium semitectum Berk. & Ravenel. Fusarium solani (Mart.) Appel & Wollenweb. emend. W. C. Snyder & H. N. Hans. was isolated from roots of more than 30% of the plants, although this is not unusually high. Crown lesions typical of charcoal rot were observed in some fields, with Macrophomina phaseolina (Tassi) Goidanich being isolated from 65% of the plants in one field. Charcoal rot was a minor problem in all fields but one. Didymella bryoniae (Auersw.) Rehm was not isolated from any of the plants. A Stagonospora-like fungus, which has been demonstrated recently as a potential contributor to vine decline (1), was isolated on 17% of the plants from five fields on the Embarcadero Farm. Monosporascus cannonballus Pollack & Uecker was isolated infrequently in one field on the Santa Rosa Farm. This is the first report of M. cannonballus and a Stagonospora-like fungus in Honduras.

Abstract Planted pastures (mainly Brachiaria spp) are the most extensive land use in the cerrado (savannas of central Brazil) with an area of approximately 50 × 106 ha. The objective of the study was to assess the effects of pasture restoration on the N dynamics (net N mineralization/nitrification, available inorganic N and soil N oxide gas fluxes—NO and N2O), C dynamics (CO2 fluxes and microbial biomass carbon), and diversity of the soil bacterial community using denaturing gradient gel electrophoresis (DGGE) profiles. Sampling was done monthly on a farm in Planaltina, Goiás, Brazil (15°13′S, 47°42′W) from November 2001 to April 2002. Three areas of cerradão (dense cerrado) were converted to pasture (Brachiaria brizantha) in 1991, and after 8 years degradation was evident with the decreasing plant biomass production. Methods to restore these pastures were investigated for their sustainability, principally their effects on trace gas emissions. The pastures have been managed since 1999 as follows: 1) fertilized plot (N = 60 kg ha−1 yr−1, P = 12 kg ha−1 yr−1); 2) grass–legume plot, Brachiaria associated with a legume (Stylosanthes guianensis) with addition of P (12 kg ha−1 yr−1); and 3) a traditional plot without management. A fourth area of cerradão was converted to pasture in 1999 and was not managed (young pasture). Ammonium was the predominant inorganic N form in the soils (∼76 mg N kg−1) for all treatments throughout the study. In December 2001 a reduction in average soil N-NH4+ was observed (∼30 mg N kg−1) compared to November 2001, probably related to plant demand. All plots had high variability of soil N gases emissions, but during the wet season, the NO and N2O soil fluxes were near zero. The results of the water addition experiment made during the dry season (September 2002) indicated that the transition of dry to wet season is an important period for the production of N gases in the fertilized pasture and in the young pasture. Soil CO2 fluxes also increased after the water addition and the grass–legume plot had the highest increase in soil respiration (from ∼2 to 8.3 μmol m−2 s−1). The lowest values of soil respiration and microbial biomass carbon (∼320 mg C kg−1 soil) tended to be observed in the young pasture, because the superficial layer of the soil (0–10 cm) was removed during the conversion to pasture. Trace gas emissions measured after the water addition experiment corresponded to rapid changes in the soil bacterial community. The young pasture sample showed the lowest level of similarity in relation to the others, indicating that the bacterial community is also influenced by the time since conversion. This study indicates that the restoration technique of including Stylosanthes guianensis with B. brizantha increases plant productivity without the peaks of N oxide gas emissions that are often associated with the use of N fertilizers. Additionally, the soil bacterial community structure may be restored to one similar to that of native cerrado grasslands, suggesting that this restoration method may beneficially affect bacterially mediated processes.

For researchers, early childhood educators, and art educators, the contribution of this article is to expand meaning in drawing activities. Perspective in reading pictures using visual culture theory, especially visual grammar. This study aims to share knowledge and experiences in reading early childhood pictures from different perspectives. This research method uses a qualitative descriptive approach through visual material data collection techniques and analysis of three metafunctions. The objects of research are three pictures of children aged 7-8 years, namely the works of winners of the I-III children's painting competition held by PP-IPTEK TMII in 2018. Aspects of the representation structure, interaction system, and composition of each image are analyzed. The research findings conclude that the ideational function of the three images shows a narrative structure of representation and raises the discourse of resistance to the actual situation. The interpersonal function of the three images places the image maker in the real world and as an object of display impersonally. The textual functions of the three images position social life on other planets as a reflection of hope for real social life.Keywords: children's drawings, visual culture, visual system, three metafunctions References: Butler, S., Gross, J., & Hayne, H.

A field experiment on the influence of different organic sources of nutrients on growth and flowering behaviour of pomegranate (Punica granatum L.) cv. Bhagwa was conducted at College Farm, College of Horticulture, Sardarkrushinagar Dantiwada Agricultural University, Jagudan, District-Mehsana in Gujarat, India during Mrig bahar (June-January) 2017-18 and 2018-19. The present investigation was laid out in Randomized Block Design with three replications consisting of twenty-two treatments with four different organic manures viz., farmyard manure, vermicompost, poultry manure and neem cake as a source of nitrogen and recommended dose of manure and fertilizers based on plant age with or without biofertilizers (Azotobacter, PSB & KMB) and biopesticides (Trichoderma viride and Paecilomyces lilacinus). The results based on pooled data revealed that a maximum number of hermaphrodite flowers (85.17) and incomplete flowers (96.50) up to two months after treatment application, fruit set (69.45 %) along with minimum fruit drop (13.18 %) and days taken for marketable picking (168.83) were significantly (@5%) noted under treatment 100 % RDN through poultry manure + 50 ml PSB + 25 ml KMB + 5 g Trichoderma viride + 5 ml Paecilomyces lilacinus. However, significantly (@5%) highest incremental primary growth parameters viz., plant height (0.60 m), plant spread (E-W: 0.41 m and N-S: 0.43 m) and stem girth (1.47 cm) after two months of treatment application were observed under treatment 100 % RDN through vermicompost + 50 ml PSB + 25 ml KMB + 5 g Trichoderma viride + 5 ml Paecilomyces lilacinus. Thus, the organic sources viz., vermicompost and poultry manure with biofertilizers and biopesticides would be very helpful for enhancing vegetative growth and flowering behaviour of the pomegranate.

A bronze portrait of a child (figs. 1-4) belonging to the category of “small format” portraits is preserved in the Archaeological Museum of Badajoz (inv. no. 4471). It was found in 1970 in excavations conducted by J. M. Peralta y Sosa on a farm in the Vega del Ortiga, an area east of Medellín in the territory between that town and Don Benito (Lusitania), some 35 km from Mérida (Augusta Emerita). In the excavated area of 40 m2 (fig. 5) were two cisterns and a rectangular well, at the bottom of which was the bronze portrait. The N cistern measured 3.8 x 1.25 m. Attached to its E side was a rectangular (80 x 60 cm) well. A channel in the centre of the S wall of the well was connected to a square (3.45 x 2.9 m) cistern. From its W wall a drain leads into a channel towards the Ortiga river, which flows by some 50 m away. On the E side of the excavation area were two identical column bases which could have belonged to a peristyle. One is a square (90 x 80 cm) block preserving traces of a column shaft 65 cm in diameter, while the other, 3 m to the north, retains the beginning of the shaft. From this point a wall (45 cm thick) faced with stucco starts to head north. The pottery found during the excavation included Arretine, South Gaulish and thin-walled wares belonging to the first quarter of the 1st c. A.D. The site appears to have been part of a Roman villa.

This study aimed to assess an in vitro antioxidant and hemolytic activities of crude hydromethanolic extract, ethyl acetate and n-butanol fractions from leaves and stems of Salvia officinalis L. Extract and fractions prepared by maceration from S. officinalis were determined for their phytochemical composition and their contents in total phenolic and flavonoid. Antioxidant activity was evaluated by the methods of DPPH radical scavenging, ferric reducing antioxidant power and total antioxidant capacity. Hemolysis assay was carried out to evaluate the toxicity of the studied samples. Crude extract and fractions from S. officinalis contain different secondary metabolites and considerable contents of phenolic and flavonoids. They exhibit high antioxidant activity and low hemolytic effect. However, ethyl acetate fraction is characterized by the highest total phenolic (362.75 ± 0.07 µg GAE/mg DE) and flavonoid (263.27 ± 0.1 µg CE/mg DE) contents. Furthermore, this fraction shows the best antioxidant activity tested by DPPH, FRAP and TAC assays. The antiradical activity of ethyl acetate fraction against DPPH (IC50 = 208.51 ± 5.77 μg/mL) is close to that of ascorbic acid (IC50 = 206.43 ± 4.16 μg/mL). It exhibits a powerful activity to reduce iron (EC50 = 250 ± 0.001 μg/mL) and the best total antioxidant capacity (817.33 ± 0.06 μg/mL). It reveals the lowest hemolysis rate of 3.77 ± 0.02% with 200 mg/mL of fraction, after one hour of incubation. The obtained results suggest that crude extract, ethyl acetate and n-butanol fractions from Salvia officinalis L. are considered efficient natural antioxidants and safe for human erythrocytes.

Abstract. The rotational Raman lidar of the University of Hohenheim (UHOH) measures atmospheric temperature profiles during daytime with high resolution (10 s, 109 m). The data contain low noise errors even in daytime due to the use of strong UV laser light (355 nm, 10 W, 50 Hz) and a very efficient interference-filter-based polychromator. In this paper, we present the first profiling of the second- to forth-order moments of turbulent temperature fluctuations as well as of skewness and kurtosis in the convective boundary layer (CBL) including the interfacial layer (IL). The results demonstrate that the UHOH RRL resolves the vertical structure of these moments. The data set which is used for this case study was collected in western Germany (50°53'50.56′′ N, 6°27'50.39′′ E, 110 m a.s.l.) within one hour around local noon on 24 April 2013 during the Intensive Observations Period (IOP) 6 of the HD(CP)2 Observational Prototype Experiment (HOPE), which is embedded in the German project HD(CP)2 (High-Definition Clouds and Precipitation for advancing Climate Prediction). First, we investigated profiles of the noise variance and compared it with estimates of the statistical temperature measurement uncertainty Δ T based on Poisson statistics. The agreement confirms that photon count numbers obtained from extrapolated analog signal intensities provide a lower estimate of the statistical errors. The total statistical uncertainty of a 20 min temperature measurement is lower than 0.1 K up to 1050 m a.g.l. at noontime; even for single 10 s temperature profiles, it is smaller than 1 K up to 1000 m a.g.l.. Then we confirmed by autocovariance and spectral analyses of the atmospheric temperature fluctuations that a temporal resolution of 10 s was sufficient to resolve the turbulence down to the inertial subrange. This is also indicated by the profile of the integral scale of the temperature fluctuations, which was in the range of 40 to 120 s in the CBL. Analyzing then profiles of the second-, third-, and forth-order moments, we found the largest values of all moments in the IL around the mean top of the CBL which was located at 1230 m a.g.l. The maximum of the variance profile in the IL was 0.40 K2 with 0.06 and 0.08 K2 for the sampling error and noise error, respectively. The third-order moment was not significantly different from zero inside the CBL but showed a negative peak in the IL with a minimum of −0.72 K3 and values of 0.06 and 0.14 K3 for the sampling and noise errors, respectively. The forth-order moment and kurtosis values throughout the CBL were quasi-normal.

Duboisia sp. is a small tree belonging to the family Solanaceae originating from the rainforest areas of the eastern coast of Australia. Dried leaves are used for the extraction of pharmaceutical alkaloids, making this a commercially viable crop. The root-knot nematode Meloidogyne incognita has been reported parasitizing Duboisia myoporoides (5); however, no information of other root-knot nematode species associated with this plant was found. Duboisia sp. is cultivated at Solana Farm, near Arapongas (23°25′08″ S, 51°25′26″ W), Paraná State, Brazil. During the renovation of a production field in this municipality, galled roots were observed on plants and samples were submitted to the Nematology Laboratory at Instituto Agronômico do Paraná, IAPAR, on December 2013. Plants did not exhibit any above-ground symptoms. The specimens were identified through perineal patterns and esterase phenotypes of 20 adult females extracted from dissected roots (2,3) and morphometrics of 10 second-stage juveniles extracted from roots using the blender-sieving method (1). Morphological characteristics were consistent with those described for M. javanica (4). Females had rounded perineal patterns with low, trapezoid shape dorsal arch, striae smooth interrupted by a pair of incisures on both sides, corresponding to lateral fields, clearly demarcated from striae by more or less parallel lines, tail whorl often distinct (4). The juvenile mean body length was 459.9 ± 28.7 μm and tail length averaged 51.6 ± 5.1 μm, with 10 to 16 μm long hyaline region and finely rounded tail tip (4). Results from the esterase electrophoresis were typical of M. javanica (2) with the J3 (Rm = 1.0, 1.3, and 1.4) phenotype being obtained. To our knowledge, this is the first report of M. javanica on Duboisia sp. in Brazil. This finding has great importance for Brazilian production since this nematode may damage plants, reduce yields, and control of this nematode on Duboisia sp. is difficult (5). Additional work is necessary in order to elucidate the losses caused by M. javanica on Duboisia sp. References: (1) J. I. Bonetti and S. Ferraz. Fitopatol. Bras. 6:533, 1981. (2) P. R.

Abstract This study aimed to evaluate the effects of dietary supplementation of rumen-protected methionine (RPM) on the body temperature and conception rate of Nelore cows exposed to high temperature and humidity index (THI) values. This study was realized on a commercial beef farm located in the north of Brazil (5º 31’ 39” S, 48º 49’ 18” W). At d-31, 31 days before the FTAI protocol, a total of 563 lactating multiparous Nelore cows were divided into two treatments, with three blocks each, the control group (CG) and methionine group (MG). Both groups were kept on tropical pastures and received a mineral supplement. The MG Group was supplemented with 3g RPM/100g during 77 days, and the expected mineral supplement intake of both groups was 100g/cow/day. Between d0 and d9 of the FTAI protocol, a subset of groups of cows (n=142) remained with a data logger attached to the progesterone device, to monitor intravaginal temperature (IT) every 30 min. During the period that the cows remained with the dataloggers the minimum, average, and maximum THI were 72.76, 78.02, and 83.28, respectively. Pregnancy diagnosis was realized 35 days after the artificial insemination and the conception rate was calculated as the number of pregnant cows/inseminated cows. Data were analyzed using the JMP GLIMMIX procedure. RPM supplementation did not affect the conception rate (CG = 64.36% vs. MG = 58.19%, P >0.05). Intravaginal temperature from day 1 to day 8, between 0630 and 2030 h and between 2200 and 0100 h were lower (P≤0.05) for MG in comparison with CG. The average and the maximum IT were, respectively, 38.94ºC, 40.88ºC for MG and 39.02ºC, and 41.38ºC for CG. In conclusion, the supplementation of rumen-protected methionine reduced the internal body temperature in Nelore cows submitted to high THI environments, during the hottest hours of the day, but does not affect the conception rate.

Amaranthus hybridus has been identified as an important alternative vegetable crop with potential for increased commercial production in South Africa (1). In summer 1999, severe losses occurred in a large plot of 2-month-old A. hybridus plants on an experimental farm near Bloemfontein, South Africa. More than 90% of the plants were severely stunted, with chlorotic foliage that was wilted in most cases. Root rot was present in all symptomatic plants and was clearly visible as an amber to brown discoloration of tap and secondary roots; in severe cases, white mycelium was clearly visible on diseased root tissue. Isolations from symptomatic roots were made on potato dextrose agar (PDA) amended with streptomycin sulfate. Isolates (N = 121) were recovered from diseased roots (n = 89). The two most frequently isolated fungi were transferred to carnation leaf agar and identified as Fusarium oxysporum (n = 90, 74%) and F. sambucinum (n = 29, 24%). Pathogenicity tests with one isolate of each species were performed in the greenhouse on 1-month-old potted A. hybridus seedlings (10 plants per treatment). A single hyphal tip of each isolate was transferred to PDA and incubated at 25°C for 7 days in the dark. Five 4-mm-diameter mycelial plugs were taken and placed directly on the taproot of each plant, halfway along the length and ≈30 mm below the soil surface. Control plants were treated with uncolonized PDA plugs. Seedlings inoculated with either fungus exhibited wilting within 7 days; stunting, chlorosis (pale green to yellow), and root necrosis after 2 weeks; and mortality after 4 weeks. Inoculated plants were removed from pots after 3 weeks, roots were washed free of potting soil, and necrotic lesion length was measured. Necrosis and discoloration of root tissue were similar to those observed in field plants. The mean length of tissue necrosis induced by the fungi was 22.5 and 34.8 mm for F. oxysporum and F. sambucinum, respectively. F. sambucinum, thus, was more pathogenic than F. oxysporum despite being recovered significantly less often from field plants. Control plants inoculated with noninfested PDA plugs remained healthy. The presence of both pathogens was confirmed by reisolation from artificially inoculated taproots of all plants. No Fusarium spp. were recovered from the 10 control treatments. F. oxysporum has been reported on diseased red root pigweed (A. retroflexus) in the United States (2), but this is the first report of both F. oxysporum and F. sambucinum as causal agents of root rot in A. hybridus. These pathogens, therefore, must be considered a potential threat to commercial production of A. hybridus in South Africa and elsewhere. References: (1) W. J. Swart et al. S. Afr. J.

Fuel cells, as a local, emission-free and versatile system, promise to overcome our dependence on fossil fuels.[1] Polymer electrolyte membrane fuel cells (PEMFCs) are considered one of the most promising technologies among the various kinds of existing fuel cells and offer an attractive alternative for automotive and stationary energy applications. Especially PEMFCs operating at an increased temperature range (MT-PEM) offer an enhanced performance. Operating temperatures between 100 – 130 °C lead to better reaction kinetics, higher tolerance to fuel impurities and to an improved heat, water and power management of the system.[2] However, some issues regarding durability and performance, such as low proton conductivity of PFSA-based membranes, higher membrane degradation and lower long-term stability at increased temperatures, are still unsolved.[3] In previous works we have shown that various metal fluorides implemented into perfluorosulfonic acid (PFSA)-membranes have a positive impact on performance and mechanical stability at operating temperatures above 100 °C.[4] In this work, we describe the modification of lithium fluoride nanoparticles, their influence on membrane durability in single cell tests at enhanced PEMFC operating temperatures and the morphology of the composite membranes, at different temperatures and degree of hydration, by in-situ small-angle X-ray scattering (SAXS). The lithium fluoride modified membrane showed increased cell performance under both standard and harsher cell conditions as well as in various long-term stability tests, such as accelerated OCV tests, load cycles and on-off cycles.One explanation for the performance boost, in addition to the increased mechanical stability of the membrane, would be an increased water uptake and storage capability, especially at low humidity levels during cell operation. We assume that the nanoparticles adsorb water molecules by hydrogen bond formation, which leads to an enhanced proton conductivity even at high temperatures. To confirm this assumption, we applied in-situ SAXS to analyze the water uptake of the modified membranes at various relative humidity and temperatures to understand the structural changes. In addition, we hope to connect different nanoparticle shapes to their influence on water uptake and retention. [1] I. Staffell, D. Scamman, A. Velazquez Abad, P. Balcombe, P. E. Dodds, P. Ekins, N.

Educators and education practitioners should be able to respond educational shift by modify paradigm of learning in the classroom. The problem that frequently emerge were the lack of conceptual and practical understanding, experience sharing among the students, as well as spirit of collaboration in learning. The purpose of the study was to build and develop students’ learning character through collaborative learning based on flipped class. The study was done in the framework of lesson study, using three steps (plan, do, and see). The technical steps included socialization, identifying problem, designing learning process, implementation, evaluation and reflection, and follow up. The result showed that collaborative learning based on flipped classroom was effective in developing the spirit of cooperation, honesty, discipline, and openness as it prioritized on the ability to cooperate with the others. There were some obstacles regarding time and class size in conducting lesson study. Keywords: Collaborative Learning, Flipped Classroom, Learning Attributes. References Agustian, A. G. (2007).

Abstract. The rotational Raman lidar (RRL) of the University of Hohenheim (UHOH) measures atmospheric temperature profiles with high resolution (10 s, 109 m). The data contain low-noise errors even in daytime due to the use of strong UV laser light (355 nm, 10 W, 50 Hz) and a very efficient interference-filter-based polychromator. In this paper, the first profiling of the second- to fourth-order moments of turbulent temperature fluctuations is presented. Furthermore, skewness profiles and kurtosis profiles in the convective planetary boundary layer (CBL) including the interfacial layer (IL) are discussed. The results demonstrate that the UHOH RRL resolves the vertical structure of these moments. The data set which is used for this case study was collected in western Germany (50°53'50.56'' N, 6°27'50.39'' E; 110 m a.s.l.) on 24 April 2013 during the Intensive Observations Period (IOP) 6 of the HD(CP)2 (High-Definition Clouds and Precipitation for advancing Climate Prediction) Observational Prototype Experiment (HOPE). We used the data between 11:00 and 12:00 UTC corresponding to 1 h around local noon (the highest position of the Sun was at 11:33 UTC). First, we investigated profiles of the total noise error of the temperature measurements and compared them with estimates of the temperature measurement uncertainty due to shot noise derived with Poisson statistics. The comparison confirms that the major contribution to the total statistical uncertainty of the temperature measurements originates from shot noise. The total statistical uncertainty of a 20 min temperature measurement is lower than 0.1 K up to 1050 m a.g.l. (above ground level) at noontime; even for single 10 s temperature profiles, it is smaller than 1 K up to 1020 m a.g.l. Autocovariance and spectral analyses of the atmospheric temperature fluctuations confirm that a temporal resolution of 10 s was sufficient to resolve the turbulence down to the inertial subrange. This is also indicated by the integral scale of the temperature fluctuations which had a mean value of about 80 s in the CBL with a tendency to decrease to smaller values towards the CBL top. Analyses of profiles of the second-, third-, and fourth-order moments show that all moments had peak values in the IL around the mean top of the CBL which was located at 1230 m a.g.l. The maximum of the variance profile in the IL was 0.39 K2 with 0.07 and 0.11 K2 for the sampling error and noise error, respectively. The third-order moment (TOM) was not significantly different from zero in the CBL but showed a negative peak in the IL with a minimum of −0.93 K3 and values of 0.05 and 0.16 K3 for the sampling and noise errors, respectively. The fourth-order moment (FOM) and kurtosis values throughout the CBL were not significantly different to those of a Gaussian distribution. Both showed also maxima in the IL but these were not statistically significant taking the measurement uncertainties into account. We conclude that these measurements permit the validation of large eddy simulation results and the direct investigation of turbulence parameterizations with respect to temperature.

The idea of edutainment began to become the interest of early childhood educators to make the learning process more holistic, including knowledge about how the brain works, memory, motivation, self-image, emotions, learning styles, and other learning strategies. This study aims to analyse and compare the effect of edutainment and group learning on the socio-emotional development of early childhood. This research method uses a quasi-experimental design with data collection techniques derived from the results of the pre-test and post-test on 20 children. The results of this study indicate that there are differences in the influence of edutainment learning with the control group on the social-emotional development of early childhood. Although both groups affect the socio-emotional development, edutainment learning has a better effect than the control group. For further research, it is recommended to create various types of edutainments learning to improve various aspects of children development.

Disciplinary behavior increases children's responsibility and self-control skills by encouraging mental, emotional and social growth. This behavior is also related to school readiness and future academic achievement. This study aims to look at read aloud with the media of large books in improving disciplinary behavior during early childhood. Participants were 20 children aged 5-6 years. By using qualitative methods as a classroom action research, data collection was carried out by observation, field notes, and documentation. The results of pre-cycle data showed that the discipline behavior of children increased to 42.6%. In the first cycle of intervention learning with ledger media, the percentage of children's discipline behavior increased to 67.05%, and in the second cycle, it increased again to 80.05%. Field notes found an increase in disciplinary behavior because children liked the media which was not like books in general. However, another key to successful behavior of the big book media story. Another important finding is the teacher's ability to tell stories to students or read books in a style that fascinates children. The hope of this intervention is that children can express ideas, insights, and be able to apply disciplinary behavior in their environment.

Resumo:

In early October of 2005, dying Salsola tragus L. (Russian thistle, tumbleweed), family Chenopodiaceae, plants were found along the Aegean Sea at Kryopigi Beach, Greece (40°02′29″N, 23°29′02″E, elevation 0 m). All of the 30 to 40 plants in the area were diseased and approximately 80% were dead or dying. All plants were relatively large (approximately 1 m tall × 0.5 m diameter), and living portions of diseased plants were flowering. Dying plants had irregular, necrotic lesions extending the length of the stems. Leaves of these plants were also necrotic. Lesions on stems and leaves were dark brown and usually coalesced. Diseased stem pieces were taken to the European Biological Control Laboratory, USDA, ARS at the American Farm School in Thessaloniki, Greece. There, diseased stem pieces were surface disinfested for 15 min with 0.5% NaOCl and placed on moist filter paper in petri dishes. Numerous, waxy subepidermal acervuli with black setae were observed in all lesions after 2 to 3 days. Conidiophores were simple, short, and erect. Conidia were one-celled, hyaline, ovoid to oblong, falcate to straight, 12.9 to 18.0 × 2.8 to 5.5 μm (mode 16.1 × 4.5 μm). These characters conformed to the description of Colletotrichum gloeosporioides (Penz.) Penz. & Sacc. in Penz. (2). Conidia were placed on modified potato carrot agar and axenic cultures from these isolations were sent to the quarantine facility of the Foreign Disease-Weed Science Research Unit, USDA, ARS, Fort Detrick, MD for testing. On the basis of DNA sequences, two variants within S. tragus have been described in California and named “Type A” and “Type B” (1). Conidia were harvested from 14-day-old cultures grown on 20% V8 juice agar, and healthy stems and leaves of 18 30-day-old plants of S. tragus Type A and 10 Type B plants were spray inoculated with an aqueous conidial suspension (1.0 × 106 conidia/ml plus 0.1% non-ionic surfactant). Three control plants of each type were sprayed with water and surfactant only. Plants were placed in an environmental chamber (18 h of dew in darkness at 25°C). After 1 day, all plants were transferred to a greenhouse (20 to 25°C, 30 to 50% relative humidity, and natural light augmented with 12-h light periods with 500-W sodium vapor lights). Lesions developed on stems of inoculated Type A plants after 5 days. After 14 days, all inoculated Type A plants were dead. Lesions on Type B plants were small and localized; all plants were diseased but no plants died. No symptoms occurred on control plants. C. gloeosporioides was reisolated 14 to 21 days after inoculation from stem pieces of all inoculated plants of both types of S. tragus. This isolate of C. gloeosporioides is a destructive pathogen on S. tragus Type A and is a potential candidate for biological control of this weed in the United States. To our knowledge, this is the first report of anthracnose caused by C. gloeosporioides on S. tragus in Greece. A voucher specimen has been deposited with the U.S. National Fungus Collections, Beltsville, MD (BPI 871126). Nucleotide sequences for the internal transcribed spacers (ITS 1 and 2) were deposited in GenBank (Accession No. DQ344621) and exactly matched sequences of the teleomorph, Glomerella cingulata.

Play-based learning activities are important programs throughout the world of children's education. Through play, children learn creatively and constructively. This study aims to solve the problem of creativity in early-childhood dance movements with the hope that there will be an increase in aspects of fluency, flexibility and elaboration through play activities related to educational dance. This action research uses an action research method which is carried out in three cycles. The subjects in this study were 19 children aged 5-6 years in Kindergarten in Central Jakarta. Data collection was carried out through observation, interviews, field notes, video documentation and photos. The findings show every child's creativity in dance movements can be improved through playing activities. Increased creativity in dance movements occurs in the aspects of fluency, flexibility, and elaboration. Another important finding, there is an increase in the optimal ability of dance creativity in the third cycle of this action research. The implication from this research is that play activities suitable for learning creative dance in early childhood must be designed as a program that emphasizes aspects of fluency, flexibility, and elaboration.

Resumo:

The present experiment was conducted on chrysanthemum (Chrysanthemum morifolium Ramat.) cv. IIHR-6 at Jambu Vadi Farm, College of Agriculture, JAU, Junagadh during winter season of 2013-14 under South Saurashtra agro climatic condition. The experiment was laid out in Randomized Block Design with Factorial concept with two time of spray viz., spray at 30 days after transplanting (S1) and spray at 60 days after transplanting (S2) and six treatment of plant growth retardants viz., MH 500 @ mg l-1 (P1), MH 700 @ mg l-1 (P2), CCC @ 2000 mg l-1 (P3), CCC @ 2500 mg l-1 (P4), PCB @ 0.4 ml l-1 (P5), PCB @ 0.5 ml l-1 (P6) were sprayed including control (P7). The effect of different time of sprays and plant growth retardants on growth, flowering and yield of chrysanthemum cv. ‘IIHR-6’ were found significant. The vigorous growth in terms of plant height at 90 DAT (52.65 cm) and at the time of final harvest (63.34 cm) was noticed the highest in control (P7) treatment while, the number of branches per plant at 90 DAT (28.80) and at the time of final harvest 34.89), plant spread in N - S (52.15 cm and 60.78 cm) and E - W direction (53.25 and 62.45 cm) at 90 DAT and at time of final harvest, respectively; fresh weight of plant (317.55 g) and dry weight of plant (35.87 g) recorded maximum under plant receiving MH @ 700 mg l-1 (P2). Consequently, these plants produced early flowers (70.94 days), took minimum days for 50 per cent flowering (101.16 days) with maximum flowering span (46.36 days), flower diameter (6.33 cm), shelf life (5.00 days) of flower as well as vase life (9.05 days) of flower. The yield of flowers (13.43 t ha -1) also produced maximum in these treatment. Interaction between different time of spray and plant growth retardants was found to be non significant in case of growth, flowering and yield of flowers, except diameters of flower. Economics of chrysanthemum indicated that the plant sprayed at 30 days after transplanting (S1) and treated with MH @ 700 mg l-1 (P2) found most remunerative as they gave highest net returns (Rs. 208980) with maximum Benefit Cost Ratio (1:4.50). It can be concluded that the foliar application of MH @ 700 mg l-1 at 30 days after transplanting proved superior in terms of growth, flowering, flower yield and more economical as compared to all other growth retardants treatments.
