Abstract:
Une base de données sur les effets de l’apport d’aliment concentré ou de matières grasses a été constituée pour quantifier la réponse du taux butyreux et de la composition en acides gras du lait chez les petits ruminants. L’apport d’aliment concentré réduit le taux butyreux, de façon plus marquée en ration complète qu’en ration fourrage - concentré séparés. Dans ce dernier type de ration, la réponse de la matière grasse du lait est curvilinéaire, un ratio fourrage concentré 1:1 maximisant la matière grasse produite. Dans ces conditions, les proportions des AG courts et moyens du lait sont peu ou pas modifiées, celles des AG longs saturés et mono-insaturés de type cis sont fortement réduites au profit des formes mono-insaturées trans et de l’acide linoléique. L’apport de matières grasses non protégées augmente généralement le taux butyreux et la matière grasse produite, de façon comparable pour les matières grasses animales ou végétales. Avec des huiles végétales ou animales, ces réponses sont très variables en fonction de l’intensité des effets dépresseurs de ces matières grasses sur la synthèse des acides gras courts et moyens, et de l’accroissement des acides gras longs. Les teneurs en acide linoléique, linolénique et CLA du lait sont accrues par les graines ou l’huile de colza, mais de façon modeste. Les huiles de poisson non protégées n’accroissent que faiblement les teneurs en acides gras poly-insaturés du lait. L’utilisation de savons de calcium (huile de palme principalement) accroît le taux butyreux de façon plus marquée chez les brebis que chez les chèvres, alors que l’accroissement de la matière grasse est comparable entre les deux espèces pour des apports jusqu’à 150 g/j. Ils réduisent la teneur du lait en AG moyens, mais pas celle des acides gras courts, ni celle de l’acide palmitique ; inversement ils induisent une forte augmentation de la teneur en acide stéarique et surtout oléique. La protection de graines ou d’huile de poisson par encapsulation permet de limiter l’effet dépresseur observé sur les acides gras courts et moyens, avec une réduction de l’acide stéarique et oléique au profit des formes trans de cet acide. Dans ces conditions, le transfert des acides linoléique et linolénique est accru en fonction de la richesse des graines pour ces acides gras. Cette forme de protection constitue un moyen modérément efficace de transférer vers le lait les acides gras polyinsaturés des huiles de poisson, ou des CLA alimentaires. L’ensemble de ces résultats fait apparaître un manque de données expérimentales chez les petits ruminants sur les facteurs alimentaires permettant de maîtriser la composition de la MG du lait, en particulier en ce qui concerne les acides gras jouant un rôle potentiel sur la santé humaine.

Abstract:
North-East India is known for its complex, diverse, risk-prone, and fragile hilly ecosystem. Natural resources in terms of soil, water, vegetation, and soil organic carbon (SOC) are much degraded. Effects of long-term perennial grasses maintained at a permanent fodder block of the ICAR Research Complex, Meghalaya, on soil quality were examined after 15 cropping cycles. The aims were (i) to ascertain whether perennial grass primarily maintained as fodder source for ruminants could conserve resources and improve soil quality in the hilly ecosystem of North-East India, and (ii) to select a suitable perennial grass to minimise land degradation, restore SOC, and improve the soil quality. Soil samples were collected in 2007–08 (dry season) from plots of 8 perennial grasses [Setaria sphacelata (setaria), Brachieria rosenesis (congosignal), Thysanolaena maxima (broom), Penicum maximum var. Makunia and var. Hamil (guinea), Pennisetum purpureum (napier), Paspalum conjugalum (paspalam), Arachis pintoi (wild groundnut)] and analysed for physical, chemical, and biological properties. A control plot had no grass cover. Hamil and Makunia produced a large amount of green fodder, while Makunia, paspalam, setaria, and congosignal had greatest root biomass. Relative to the control, soil under perennial grasses showed increases of ~30% SOC, 70% mean weight diameter, 20% available soil water, 40% hydraulic conductivity, 63% infiltration rate, and 10% soil microbial biomass carbon. Among grasses, soil under setaria, congosignal, and Makunia had higher values of these attributes than under other species because of better soil binding through an extensive root system. Improvement of soil physical properties and processes under these grasses, coupled with complete ground cover, reduced soil erosion by ~33% and also signified ecological benefits through C-sequestration. Soil quality management in the fragile ecosystem of North-East India should include permanent pastural grasses, particularly, setaria, congosignal, and Makunia.

Abstract:
The quality of three year-long green and three summer-growing, frost-susceptible perennial native grasses was compared with that of two introduced temperate perennial grasses and white clover (Trifolium repens L. cv. Haifa). Digestibility of white clover generally exceeded that of all grasses, except for the green leaves of the two introduced species, Festuca arundinacea Screb. cv. Demeter and Phalaris aquatica L. cv. Sirosa, during winter. The digestibility of the green leaves of most winter-green species increased during winter and decreased in summer, the extent of this being greater for the introduced grasses.The digestibility of fescue and phalaris was generally similar throughout the study and was mostly higher than that of the native grasses, but the quality of the green leaves of two year-long green native species, Danthonra linkii Kunth and Microlaena stipoides (Labill.) R.Br., approached that of the two introduced grasses. The quality of the summer perennial species was poor during winter owing to the presence of only dead leaves, but the green leaves of Bothriochloa macra (Steud) S. T. Blake retained high levels of digestibility during summer. Considerable variation in digestibility exists between individual plants of Poaseiberana Spreng, indicating that opportunities may exist for selection of highly productive lines from some native species.In pen-feeding studies, voluntary intake of most of the year-long green native grasses was similar to that of the introduced grasses, but intake of the summer perennial species tended to be lower.Results from this study indicate that the quality of native pastures and their potential for animal production will vary considerably according to species composition, season and the presence of white clover.

Abstract:
This paper presents findings of comparative evaluation of selected soil physical quality (SPQ) indicators, obtained from fields subjected to: >50 years of cultivation of three perennial pasture grasses (i) Digitaria smutsii (DS), (ii) Brachiaria decumbens (BD), and (iii) Andropogon gayanus (AG); (iv) >50 years of continuous cultivation (CC) of cereals–legumes; and (v) >20 years of natural fallow (NF). The study was aimed at identifying the land-use system having optimal values for SPQ. Fields under CC had the highest bulk density, and the lowest total porosity (PORt) and macroporosity (PORp), field capacity (FC), and available water capacity (AWC). Perennial pasture grasses fields had significantly higher organic carbon, PORt, FC, AWC, and saturated hydraulic conductivity, and, hence, had better SPQ than CC fields and, in some instances, NF fields. The usefulness of ratios FC/PORt = 0.66 and ACt/PORt = 0.34 as additional indicators for assessing soil response to land-use systems was not proven in this study, and therefore, further studies should be conducted on the subject matter. Pasture grasses improved SPQ values relative to continuous cereal–legume cropping and fallow. The SPQ under CC and NF fields might be best improved by applying organic matter.

Full text
Abstract:
Preliminary phytolith analysis of ephemeral lake fill sediment at Long Pocket, near Toomba, northeast Queensland, Australia, indicates that a C4-dominated grassland with a minor woody component has been present in the region since ca. 8000 cal yr B.P. Based on the modern distribution of C4 and C3 native grasses in Australia, this suggests that mean summer temperatures of at least 14°C (ca. 10°C cooler than present) were maintained since the early Holocene. This interpretation is comparable with previous studies, which together imply that the establishment of C4-dominated grasses in central and northeast Australia occurred between the last glacial maximum (most likely after ca. 16,000 14C yr B.P.) and ca. 7200 14C yr B.P. (ca. 8000 cal yr B.P.). Taxonomic composition of the grassland appears relatively consistent since the early Holocene at Long Pocket and includes phytoliths comparable with those from modern Arundinoideae, Panicoideae, and Chloridoideae. Rare non-grass phytoliths are also present. A gradual decrease in abundance of saddle phytolith forms (attributed to Chloridoideae grasses) from the base of the record at ca. 6500–7000 cal yr B.P. suggests decreasing aridity throughout the Holocene. This trend could reflect a locally drawn out effect of the end of the postglacial arid period due to the well-drained basalt flow catchment maintaining a local arid habitat for the Chloridoideae grasses.

Abstract:
Grasses, by their high productivity even under very low p CO 2 , their ability to survive repeated burning and to tolerate long dry seasons, have transformed the terrestrial biomes in the Neogene and Quaternary. The expansion of grasslands at the cost of biodiverse forest biomes in Madagascar is often postulated as a consequence of the Holocene settlement of the island by humans. However, we show that the Malagasy grass flora has many indications of being ancient with a long local evolutionary history, much predating the Holocene arrival of humans. First, the level of endemism in the Madagascar grass flora is well above the global average for large islands. Second, a survey of many of the more diverse areas indicates that there is a very high spatial and ecological turnover in the grass flora, indicating a high degree of niche specialization. We also find some evidence that there are both recently disturbed and natural stable grasslands: phylogenetic community assembly indicates that recently severely disturbed grasslands are phylogenetically clustered, whereas more undisturbed grasslands tend to be phylogenetically more evenly distributed. From this evidence, it is likely that grass communities existed in Madagascar long before human arrival and so were determined by climate, natural grazing and other natural factors. Humans introduced zebu cattle farming and increased fire frequency, and may have triggered an expansion of the grasslands. Grasses probably played the same role in the modification of the Malagasy environments as elsewhere in the tropics.

Full text
Abstract:
This thesis investigates the extent to which human rights law may be used to challenge the forced eviction of people who live in public space under public space laws. The specific case study is the operation of Darwin City Council By-law 103, which bans camping, or adults sleeping in a public place between sunset and sunrise. The by-law is used to criminalise or forcibly evict people who live in public space in Darwin in the Northern Territory. Darwin has the highest proportionate number of homeless people of any capital city in Australia. Indigenous people are significantly over-represented. The thesis charts recent legislative changes across Australia to demonstrate that public space laws, such as Darwin City Council By-law 103, continue to be popular public policy responses to law and order concerns. This legal regulation is being undertaken without ensuring compliance with international human rights standards. There has been a marked increase in Australia of the use of available domestic and international human rights tools to raise concerns about the enforcement of these laws against people living in public space. Through a review of secondary sources, the thesis establishes that some 15 human rights have been identified as potentially engaged by such enforcement but Australian jurisprudence has yet to emerge. The thesis selects the human right to privacy, family and home for detailed analysis. It interrogates available evidence from Darwin, international and comparative jurisprudence and secondary sources to determine whether the forced eviction of people living in public space under Darwin City Council By-law 103 may be found to violate the right to respect for privacy, family and home in a particular case. The study aims to make a specific contribution to growing endeavours to promote the human rights of people who are homeless, including people who live in public space. Its detailed analysis is designed to support a human rights litigation strategy at both domestic and international level, in order to challenge the extent to which people living in public space are subjected to criminalisation and forced eviction when they have nowhere else to live.

Abstract:

California grasslands are well known for the exotic species invasions they have undergone and the resulting decrease in native flora. Issues with restoring these lands lie in determining the pre-invasion vegetation composition and the mechanisms of invasion. This study compares data from three surveys of a set of permanent quadrats in La Jolla Valley in order to determine changes over time. Each iteration included data on vegetation cover, frequency, and shrub density. It was found that native grass cover has decreased, and exotic grass cover has fluctuated widely. Also, both native and exotic forb cover increased greatly. This supports Minnich’s forb-field theory over Clements’ bunchgrass theory. The natural enemies and disturbance hypotheses did not accurately predict these results. When the quadrats were divided in valley floor and valley edge categories the post-disturbance hypothesis accurately predicted the result that edge quadrats have greater native grass cover than their floor counterparts.

Abstract:
INTRODUCTION Carnitine palmitoyltransferase I, which is expressed in the pancreas as the liver isoform (LCPTI), catalyzes the rate-limiting step in the transport of fatty acids into the mitochondria for their oxidation. To directly examine whether the availability of long-chain fatty acyl-CoA affects the regulation of insulin secretion in the Beta-cell, we infected INS(832/13) cells and rat islets with an adenovirus encoding a mutant form of LCPTI (Ad-LCPTI M593S) that is insensitive to its inhibitor malonyl-CoA. C75 is described as a potential drug for treatment of obesity and type 2 diabetes. First known as a synthetic inhibitor of fatty acid synthase, it has been also described as an activator of CPTI, increasing peripheral energy utilization and fatty acid oxidation in mice. To further investigate the C75/CPTI interaction, we have characterized the effects of C75 on CPTI in vitro and in vivo.

OBJECTIVES 1) Study of the malonyl-CoA/CPTI interaction in the pancreatic Beta-cell and its involvement in glucose-stimulated insulin secretion (GSIS). 2) Construction of an INS stable cell line overexpressing LCPTI wt and LCPTI M593S. 3) Determine the effect of C75 on the CPTI activity and palmitate oxidation in pancreatic Beta-cells.

RESULTS. In Ad-LCPTI M593S infected INS(832/13) cells LCPTI activity increased six-fold. This was associated with enhanced fatty acid oxidation, at any glucose concentration, and a 60% suppression of GSIS. In isolated rat islets in which LCPTI M593S was overexpressed, GSIS decreased 40%. At high glucose concentration, overexpression of LCPTI M593S reduced partitioning of exogenous palmitate into lipid esterification products, and decreased PKC activation. Moreover, LCPTI M593S expression impaired KATP channel-independent GSIS in INS(832/13) cells.
INS-1 stable clones of LCPTIwt and LCPTImut were constructed, however none of them resulted in an increase in LCPTI protein expression compared to endogenous LCPTI nor in CPTI activity. Therefore, slight basal overexpression of LCPTI could probably be toxic for the cells, as a result of which only those cells that do not contain the LCPTI plasmids survived throughout cell passages.
When INS(823/13) cells are incubated with C75, CPTI activity is inhibited, as is fatty acid oxidation. In vivo, a single intraperitoneal injection of C75 to mice produces a short-term inhibition of CPTI activity in mitochondria from liver and pancreas.

DISCUSSION. The results with LCPTImut provide direct support for the hypothesis proposing that the malonyl-CoA/CPTI interaction is a component of a metabolic signalling network that controls insulin secretion. Overall, the findings with C75 provide compelling evidence that the drug is a potent inhibitor of CPTI.

Abstract:
Perennial grass vegetation dynamics of heavy grazing, moderate grazing and ungrazed treatments were analyzed during two extreme drought events: the drought of 1951 to 1956 and the drought events centered on the year 2000. Analysis of each drought event from weather records and Palmer Drought Severity Index values showed that the intensity, duration and pattern of each drought event were structurally unique. Grazing intensity was the primary driver of perennial grass species composition and community structure both during and between each drought event. Total basal area for each drought event was driven primarily by variation in precipitation pattern. Basal area per plant dynamics were significantly influenced by grazing intensity while plant density was driven by both precipitation and grazing intensity. Topo-edaphic variation significantly influenced the persistence and distribution of perennial grass species during an extreme drought event centered on the year 2000. The presence of large or abundant surface rock features facilitated the survival of perennial grasses during this drought event by creating a positive soil microenvironment. Sites with large surface rock features acted as drought refugia for perennial grass populations. Sites with abundant surface rock features had 10 times greater perennial grass basal area and 5 times greater plant density than sites with few surface rock features. Grazing intensity was the primary driver of species composition and community structure within both refugia and non-refugia sites. Grazing intensity had no effect on perennial grass basal area. However, grazed treatments had two times greater perennial grass density than non-grazed treatments. Species response to grazing intensity and surface rock cover was individualistic. Grazing response groups (intolerant, intermediate, and tolerant) separated along a gradient of surface rock cover and grazing intensity. Abundant surface rock features act as refugia for perennial grasses by facilitating their persistence during extreme drought events on the Edwards Plateau.

Full text
Abstract:
The potential of red meat, particularly that produced from grass-fed animals, to contribute to dietary intakes of long chain (LC) n-3 PUF A has become the focus of recent research. However, there remains little information on precise quantities of these fatty acids found in commercially produced red meat, the use of grass finishing diets by producers, or the ability of red meat produced from grass feeding regimes to contribute to LCn-3 PUF A intakes or status in consumers, especially in the UK and Ireland. Extensive fatty acid data were measured for beef and lamb produced in Northern Ireland over a 12 month period and the frequency of a grass diet being offered to animals before slaughter was determined by a survey carried out among a sample of beef and lamb producers. To investigate the effect of consumption of red meat produced from grass-fed animals on LCn-3 PUF A status, a human intervention study was carried out among healthy subjects. In addition, the potential for red meat produced from grass-fed animals to contribute to LCn-3 PUF A intakes in the Irish population was hypothetically assessed based on current intakes of meat. Beef and lamb were reported to contain concentrations ofLCn-3 PUFA similar to levels achieved with grass feeding by other studies. The season of slaughter and, to a lesser extent, the reported finishing diet of the animal were found to cause variation in concentrations ofLCn-3 PUFA and conjugated linoleic acids (CLA) found in beef and lamb. The survey revealed that grass finishing diets are commonly offered to animals by producers of beef and lamb, but the frequency of these diets also varied by season. In the human intervention study, consumption of red meat from grass-fed animals was associated with significantly increased plasma and platelet LCn-3 PUF A status among healthy subjects. Based on red meat consumed in the Irish diet being from grass-fed animals, the provision of red meat to LCn-3 PUF A intakes would be modestly increased than if meat consumed were from concentrate-fed animals. In conclusion, the production of red meat from grass-fed animals will contribute to increased LCn-3 PUF A intakes and status among Irish consumers, where red meat is habitually consumed. Further research is warranted to investigate the opportunity to further enhance concentrations ofLCn-3 PUF A within red meat by increased use of grass feeding regimes in beef and lamb production.

Full text
Abstract:
I sought to determine the effect of managed flooding on Phalaris arundinacea L. and other plant species distributions in a large wetland complex, Smith and Bybee Wetlands (SBW), in northwestern Oregon. Altered hydrology has reduced historically high spring flow and prematurely initiated the historic summer drying period at SBW. This alteration has increased the coverage of invasive plants (e.g., P. arundinacea) causing a decrease in native plant cover and thus degrading ecological functions. SBW managers installed a water control structure (WCS) between SBW and the Columbia Slough/River system to impound winter rainfall and thus approximate the ecological benefits that natural flooding provided as well as reduce the abundance of P. arundinacea. Prior researchers conducted intensive vegetation and hydrological monitoring in 2003 (during the season immediately before WCS installation) and 2004. I conducted similar analysis in the fifth and sixth years, 2008 and 2009, following establishment of the WCS. Both study years, I determined percent cover of all vegetation on transects established in 2003. The results, including 2004, as well as 2008 and 2009 showed a reduced cover of P. arundinacea in areas experiencing at least 0.6 meters of inundation and an increased cover of native plant communities when compared to the 2003 baseline data. Native Carex aperta Boott. cover increased 7-fold from 0.3% to 2.3%; Polygonum species cover increased from 20.0% to 52.6%; and Salix lucida Muhl. ssp. lasiandra (Benth.) E. Murray cover increased from 10.9% to 15.5% cover. P. arundinacea declined by over one-third from 44.4% to 28.1% cover following water management. Since hydrology management began, the native Polygonum species community replaced P. arundinacea as the dominant species in the emergent zone. The results of this study refined the suggested depth of inundation needed to reduce P. arundinacea cover in such lake-wetland complexes as SBW from 0.85 meters (based on 2004 study results) to 0.6 meters. Shannon Diversity decreased following water management. The findings of this study demonstrated that water management can enhance native bottomland communities, especially those comprised of obligate wetland species, and reduce P. arundinacea cover in areas experiencing at least 0.6 meters of inundation.

Abstract:
Quantificou-se o teor de lignina em cinco amostras de plantas forrageiras, nas frações caule e folha, em quatro estádios de maturidade, através de três métodos analíticos: lignina detergente ácido (LDA), lignina permanganato de potássio (LPer) e lignina Klason (LK), todos de natureza gravimétrica. Os três métodos não foram concordantes entre si, sendo que para a maioria das amostras, o método LK mostrou valores mais elevados que os outros dois métodos, e o método LDA exibindo os menores valores. A fração caule exibiu teores mais elevados de lignina do que a folha; forrageiras maduras mostraram maiores concentrações de lignina do que plantas mais novas. Para quase todas as amostras, a digestibilidade in vitro da matéria seca foi negativamente correlacionada com os teores de lignina estimados pelos três métodos analíticos. O método LDA estimou razoavelmente bem a digestibilidade de forrageiras, seguindo-se a LPer. A LK não estimou bem a digestibilidade de gramíneas. Conclui-se que, nenhum dos três métodos foi totalmente satisfatório, sugerindo que a determinação analítica da lignina seja mais profundamente estudada. Este trabalho também quantificou as frações de carboidratos pelas equações da ″Cornell Net Carbohydrate and Protein System (CNCPS)″. A utilização da preparação parede celular (PC) nas equações da CNCPS, em substituição à fibra em detergente neutro (FDN), não proporcionou diferenças quanto aos teores de carboidratos de todas as frações. Porque foi realizada a comparação entre PC e FDN, foi descoberto que a equação da fração C, que estima os carboidratos indigeríveis da parede celular, pode ser simplificada, relacionando a fração indigerível em função do teor de lignina na matéria seca, e não em função da FDN, como é atualmente amplamente utilizado. Em outras palavras, o cálculo da fração indigerível da parede celular pode ser obtido independentemente da FDN isenta de cinzas e proteína. Como os valores da fração B1 (amido e pectina) pelo sistema CNCPS foram menores em relação à determinação laboratorial e com base nos resultados obtidos pelo emprego da PC nas equações de Cornell, sugere-se que a fração B2 seja destinada exclusivamente à pectina. E para os carboidratos digeríveis da parede celular, uma nova fração seja denominada, a B3 . Evidências colhidas na presente pesquisa sugerem que, pelas equações de Cornell, a pectina nunca esteve presente na fração B1 e sim na fração A. Portanto, do conteúdo da fração A, dever-se-ia subtrair o valor da pectina. A fração C continuaria inalterada e a fração B1 seria constituída apenas de amido
Lignin was quantified in five forage samples, in the fractions stem and leaf, at four maturity stages, through three analytical methods: acid detergent lignin (ADL), permanganate lignin (PerL) and Klason lignin (KL), all gravimetric procedures. The three techniques yielded different values for the same samples; in general, the KL method showed higher lignin concentrations than the two other methods, being the ADL which showed the lowest data. Stem fraction exhibited higher levels of lignin than leaf tissue; mature forages had higher concentrations of lignin than younger plants. For almost all the samples, lignin concentration was negatively correlated with the in vitro dry matter digestibility. The method ADL estimated reasonably well the digestibility of grasses, followed by PerL. The KL method was not a good predictor of digestibility of grasses. It was concluded that none of the three methods was totally satisfactory, suggesting that the analytical determination of lignin should be more deeply studied. This work also quantified the carbohydrate fractions through the Cornell Net Carbohydrate and Protein System (CNCPS). The utilization of crude cell wall instead of neutral detergent fiber in the CNCPS equations showed no differences in the estimates of all carbohydrate fractions. Because it was made a comparison between CW and NDF, it was discovered that the equation for the fraction C could be simplified where lignin expressed as a ratio of NDF, could be described on dry matter basis and not on NDF basis as it is largely used nowadays. In another words, estimate of indigestible cell wall could be obtained independently of ash + protein-free NDF. Because estimates of B1 fraction (starch and pectin) by means of CNCPS equations were lower than wet chemistry determinations and based on the results obtained by the substitution of NDF for PC in the Cornell equations, we suggest that B2 fraction be allocated exclusively for pectin. And for the digestible cell wall carbohydrates a new fraction, B3, be named. Evidences collected in the present experiment suggest that in the Cornell equations pectin was never part of B1 fraction but present in the A fraction. Thus, from the content of fraction A, pectin must be subtracted. The fraction C would remain unaltered and the fraction B1 would be constituted only by starch

The occurrence of late season leaf diseases (DFC) caused by Septoria glycines and Cercospora kikuchii and powdery mildew caused by Microsphaera diffusa in soybean (Glycine max) are easily identified in field. In recent years, there has been a seach for alternatives to fungicides that provide satisfactory disease control with low environmental impact and low toxicity to human. The objective of this study was to evaluate the effect of extract of C. citratus, R. officinalis and C. longa and by curcumin solutions, to control DFC and powdery mildew. In vitro assays were conduced to verify the antimicrobial activity of those plant extracts, by evaluation of the mycelial growth of C. kikuchii in PDA medium. Additionally, assays under field conditions were carried out with soybean cv. CD 215. The pyraclostrobin + epoxiconazole fungicide (0,6 L c.p. ha 1) was used as control. Extract of C. citratus inhibited the mycelial growth of C. kikuchii in 36,9%, to concenttrations up to 10% of the extract. To R. officinalis, the inhibited was 42,8% to concentration 10%. The lower antimicrobial activity was with C. longa with 17,9% of inhibition concentration 20%. In relation to field assays extract of C. longa 5% was higher than the control with water to the weight of one hundred seeds, like as C. citratus 5% and R. officinalis 5 and 10 %. The production of the extract of C. longa at 10% was 3856 kg ha-1 with good control of diseases. R. officinalis at 5% showed production higher than the control with water. Those two treatments were 15% higher in relation of grain production than fungicide. The C. citratus and C. longa, both with 5%, and the chemical reduced the severity of late season diseases. The better control of powdery mildew was with extract of C. citratus and R. officinalis at 5%, C. longa at 5 and 10% and the fungicide. R. officinalis and C. longa at concentration of 5% were statistically different in relation to enzymatic peroxidase activity, however lesser the control with water. These results indicate that in spite of reducing diseases severity in soybean with the use of C. longa, C. citratus and R. officinalis extracts, this is have not relations with a probably activation of peroxidase activity and that, possibly, other plant defense mechanisms, or a direct antimicrobial activity, maybe envolved in the control of late season leaf disease and powdery mildew
A ocorrência das doenças foliares de final de ciclo (DFC) causadas por Septoria glycines e Cercospora kikuchii e oídio causada por Microsphaera difusa em soja (Glycine max) são facilmente observadas no campo. Várias alternativas aos fungicidas têm sido avaliadas nos últimos anos na busca de produtos que controlem satisfatoriamente as doenças, que tenham pequeno impacto ambiental e baixa toxicidade aos seres humanos. O objetivo deste trabalho foi avaliar o efeito de extratos Cymbopogom citratus, Rosmarinus officinalis e Curcuma longa e solução de curcumina no controle de DFC e oídio. Foram realizados ensaios in vitro para verificar a atividade antimicrobiana desses extratos, através da análise do crescimento micelial em meio BDA bem como ensaios em condições de campo, com a cultivar de soja CD 215. O fungicida pyraclostrobin+epoxiconazole (0,6 L p.c. ha-1) foi utilizado como tratamento controle. Os extratos de C. citratus foram os que mais inibiram o crescimento micelial de C. kikuchii, com valores de até 36,9% para concentrações a partir de 10% do extrato. Para R. officinalis, as inibições foram verificadas apenas a partir da concentração de 10% do extrato, alcançando o valor de 42,8% de inibição, para o extrato a 20%. C. longa foi a planta com menor atividade antimicrobiana, com inibição de apenas 17,9% para o extrato a 20%. Para a curcumina, soluções a partir de 200 mg L-1, inibiram em média 15,1% o crescimento micelial in vitro do patógeno. Com relação aos ensaios de campo, verificou-se que a massa de 100 grãos do tratamento com C. longa (5%) foi superior à testemunha, porém igual a C. citratus (5%) e R. officinalis (5 e 10 %). Todos esses valores foram superiores ao tratamento com fungicida. Para a variável massa total o tratamento com C. longa (10%) obteve produtividade de 3856 kg ha-1 mostrando também bom controle de DFC e oídio. Extrato de R. officinalis (5%) também proporcionou produção de grãos estatisticamente superior ao tratamento com fungicida. Nesses dois tratamentos a produção foi em média 15% superior àquela com produto químico. O melhor controle de DFC ocorreu nos tratamentos com C. citratus e C. longa, ambas a 5%, e com o fungicida. O melhor controle de oídio ocorreu com extratos de C. citratus e R. officinalis (5%), C. longa (5 e 10%) e fungicida. Os tratamentos com C. longa e C. citratus foram estatisticamente iguais ao fungicida. Para a atividade de peroxidase, R. officinalis e C. longa (5%) resultaram em valores estatisticamente diferentes da testemunha, porém inferiores a esta. Estes resultados indicam que embora tenha ocorrido redução da severidade de DFC e oídio em soja com os extratos de C. longa, C. citratus e R. officinalis, este evento provavelmente não esteja relacionado com alguma possível ativação ou indução da atividade de peroxidases e que, possivelmente, outros mecanismos de defesa da planta, ou mesmo uma atividade antimicrobiana direta, possam estar envolvidos no controle destas doenças

Abstract:
Poetry has long been concerned with truth grasped as a form of communicable proof. But poets know about failed communication, too: when Virgil’s Aeneas tries, three times, to embrace the shade of his dead father, he moves to a distinctive ternary rhythm; one that is repeated throughout human history. This chapter, centred on a close reading of ‘Album, V’, part of Seamus Heaney’s final collection, Human Chain, discusses the experiments in inference which poetry enacts as a sustained, reflexive inquiry into the conditions and limits of communicability. Exploring both intertextual relations between ancient and modern poets and the contextual implications of shared sights, sounds, memories, gestures, and words, Heaney’s work moves between languages, genres, and generations. In so doing, it exemplifies the enduring salience and force of what Sperber and Wilson term ‘poetic effects’: generating common knowledge, they prove to be links in the chain of human, embodied cognition.

Abstract:
Over the past half a century research has revealed that marsupials – far from being ‘second class’ mammals – have adaptations for particular ways of life quite equal to their placental counterparts. Despite long separate evolution, there are extraordinary similarities in which marsupials have solved the challenges of living in such environments as deserts, alpine snowfields or tropical rainforests. Some can live on grass, some on pollen and others on leaves; some can glide, some can swim and others hop with extraordinary efficiency. In Life of Marsupials, one of the world’s leading experts explores the biology and evolution of this unusual group – with their extraordinary diversity of forms around the world – in Australia, New Guinea and South America.

Abstract:
Latin America has a long urban tradition. Since the middle of the nineteenth century, it has been more urbanized than any other region on the globe except North America, northwestern Europe, and Australia/New Zealand. This has produced large urban working classes, large labor movements, and an equally large—and by now traditional—labor historiography, particularly in Latin America itself. This article discusses trends that have shifted the focus from organized labor to workers themselves and their sociocultural world inside and outside the factory. It covers working-class formation during the second half of the nineteenth century, the influence of anarchism and socialism on labor and urban life from the 1880s to the Great Depression, the relationship of organized labor and populist regimes from the latter event to the 1960s, and the emergence since then of what has been called “new unionism,” a more politically independent and grass-roots form of labor mobilization.

Full text
Abstract:
Sri Ramakrishna is widely known as a nineteenth-century Indian mystic who affirmed the harmony of all religions on the basis of his richly varied spiritual experiences and eclectic religious practices, both Hindu and non-Hindu. In Infinite Paths to Infinite Reality, Ayon Maharaj argues that Sri Ramakrishna was also a sophisticated philosopher of great contemporary relevance. Through a careful study of Sri Ramakrishna’s recorded oral teachings in the original Bengali, Maharaj reconstructs his philosophical positions and analyzes them from a cross-cultural perspective. Sri Ramakrishna’s mystical journey culminated in the exalted state of “vijñāna,” his term for the “intimate knowledge” of God as the Infinite Reality that is both personal and impersonal, with and without form, immanent in the universe and beyond it. This spiritual standpoint of vijñāna, Maharaj contends, opens up a new paradigm for addressing central issues in cross-cultural philosophy of religion, including the infinitude of God, religious diversity, mystical experience, and the problem of evil. Sri Ramakrishna’s vijñāna-based religious pluralism—when grasped in all its subtlety—proves to have major philosophical advantages over dominant Western models. Moreover, his mystical testimony and teachings not only cut across long-standing debates about the nature of mystical experience but also bolster recent defenses of its epistemic value. Maharaj further demonstrates that Sri Ramakrishna’s unique response to the problem of evil resonates strongly with Western “soul-making” theodicies and contemporary theories of skeptical theism.

In the absence of top-dressing and when using low doses of fertilizers, pasture-type herbage is formed with the predominance of grass-roots types of grasses. Highly productive grass of the haymaking type is preserved against the background of the use of a complex of fertilizers with a nitrogen dose of more than 90 kg/ha.

Full text
Abstract:
A number of sites around the United States have used activated carbon (AC) amendments to remedy contaminated sediments. Variation in site-specific characteristics likely influences the long-term fate and efficacy of AC treatment. The long-term effectiveness of an AC amendment to sediment is largely unknown, as the field performance has not been monitored for more than three years. As a consequence, the focus of this research effort was to evaluate AC’s long-term (6–10 yr) performance. These assessments were performed at two pilot-scale demonstration sites, Grasse River, Massena, New York and Canal Creek, Aberdeen Proving Ground (APG), Aberdeen, Maryland, representing two distinct physical environments. Sediment core samples were collected after 6 and 10 years of remedy implementation at APG and Grasse River, respectively. Core samples were collected and sectioned to determine the current vertical distribution and persistence of AC in the field. The concentration profile of polychlorinated biphenyls (PCBs) in sediment pore water with depth was measured using passive sampling. Sediment samples from the untreated and AC-treated zones were also assessed for bioaccumulation in benthic organisms. The data collected enabled comparison of AC distribution, PCB concentrations, and bioaccumulation measured over the short- and long-term (months to years).

Full text
Abstract:
A Grant Agreement between the Government of Australia and the World Organisation for Animal Health (OIE), the Stop Transboundary Animal Diseases and Zoonoses (STANDZ), initiative includes a rabies component with an overarching intended outcome of reducing dog rabies incidence in targeted areas. This initiative envisaged regional rabies activities in South-East Asia as well as specifically designed pilot projects in the Philippines, Myanmar and Cambodia. While remaining anchored to the envisioned outcome, its implementation from 2013 to 2016 also leveraged on the resources made available through the initiative to strategically generate tools, materials and examples that can potentially bridge long-standing gaps on dog rabies elimination in the region. This included developing approaches on rabies communication strategy, risk-based approach for the prioritization of mass dog vaccination, rabies case investigation, post-vaccination monitoring, building capacity through pilot vaccination projects, One Health operationalization at the grass-root level, and reinforcing high-level political support through regional and national rabies strategy development. These are briefly described in this paper and are also further detailed in a series of publications which individually document these approaches for future utility of the countries in the region, or wherever these may be deemed fitting. The STANDZ rabies initiative leaves behind a legacy of materials and mechanisms that can potentially contribute in strategically addressing rabies in the region and in achieving the global vision of eliminating dog-mediated human rabies by 2030.
