Depuis plus de trente ans, les cultures sportives s'approprient l'espace urbain et périurbain et rythment le temps des villes. Les sports de compétition se sont développés, le spectacle sportif envahit les média, les pratiques autorégulées dans les espaces publics se sont multipliées et le désir de nature et de mobilité n'a fait que s'accentuer. Ces évolutions touchent l'ensemble de la société française mais elles prennent à Bordeaux des configurations particulières en raison d'une histoire originale, d'un rapport spécifique aux lieux et des modes particuliers de gestion locale qui donnent une coloration propre au vécu et à l'imaginaire des cultures sportives bordelaises.

Texto completoResumen
The subgenus Parapisa of the genus Apisa is reviewed based on the examination of 104 specimens. Apisa (P.) cinereocostata and A. (P.) subargentea are redescribed and their intraspecific variation is analysed in detail. A new species A. (P.) asipa, similar in the general coloration to other Apisa taxa, but very distinctive in the male genital morphology and the shape of the wing scales, is described from Cameroon and Nigeria. Apisa (P.) cinereocostata is hypothesized to be a widespread, but highly polymorphic taxon with significant variation in body size, intensity of grey coloration, and the proportions and shape of certain morphostructures of male genitalia. Determination keys and extensive illustrations of the variation are provided to enable proper identification of specimens.

Snakehead (Betta channoides) is a native and endemic fish from East Kalimantan. It has a beautiful and attractive color as an ornamental fish commodity. This fish is incubating her eggs in its mouth or a mouthbrooder. The important thing in spawning is male brood selection, it is related to eggs incubating and also proper harvests time and technique in order to maximize the result. The aim of this research is to determine the criteria for good male broodstock used in spawning, proper time to harvest the larvae and the effectiveness of shaking technique to harvest the larvae. There are two criteria selecting male broodstock, 1. Mouth shape and 2. Body coloration. Determination of harvest time was carried by harvesting larvae 4th, 8th and 12th day after spawning. The effectiveness of shaking technique was seen by comparing with broodstock natural larva released. The parameters that observed in this research were the shape of male broodstock, male body color, the number of harvested larvae and harvesting time between shaking technique and naturally released by male. The result showed that selection of male snakehead betta good for spawning was the male broodstock with wider mouth shape and have width of 0.5cm also with not too bright red body coloration. The proper harvesting time for maximum yield was the 8th day after spawning. The shaking technique in harvesting is more effective in harvest time, number of larvae, survival rate of larvae and its simplicity comparing to natural released by broodstock. Keywords: selection, male broodstock, larva harvest, shaking, B. channoides

Abstract Dyes synthesized by condensation of e. g. 4-N,N-dialkylaminobenzaldehydes, 5-N,N-dialkylamino-2-thiophenaldehydes or 5-N,N-dialkylamino-2-furaldehydes, with open chain active methylene compounds have been given the labels merocyanine, neutrocyanine, methine or styryl dyes. All these classifications are misnomers. In terms of systematic nomenclature, their proper classification is as streptomerocyanine dyes. They are used in textile coloration and in dye diffusion thermal transfer printing (D2T2). Furthermore, they have been investigated for their potential as sensitizer dyes in dye sensitized solar cells (DSSC) and for photorefractive applications.

The efficient and durable coloration of cars at their manufacturing and repair needs preparation of surfaces to be painted which consists in ensuring their quality and forming proper roughness required for painting and degreasing. The paper reports the standard method offered for the assessment of technical and economical efficiency of railroad car metal surface processing with a free abrasive based on data of processing modes, materials used and quality of a clean surface obtained.
For this at the initial stage there was carried out the analysis of standards in the field of a metal pre-coloration processing for the purpose of the require-ments to the quality of a surface to be clean, roughness and a degree of degreasing. In the corresponding stand-ards there are defined three basic groups of surface preparation quality, which may be conditionally subdi-vided into high, average and low quality. The assess-ment of processing efficiency was carried out under a condition of ensuring the first quality group. For that there was carried out a comparison of four standard technologies of metal pre-painting for the purpose of the process efficiency, material consumption (power) and surface processing quality obtained. The comparison has shown that the highest effectiveness has a technology of thermal abrasive-jet processing. This technology allows avoiding chemical agents use for metal surface degreasing which allows decreasing material capacity of the process and increasing considera-bly a pre-painting productivity.

In this study about spessartines,13 spessartine samples with proper conditions are used for FTIR spectrum and UV-Vis spectrum tests to find the gemological characteristics and coloration mechanism. In the UV-Vis spectrum, spessartines’ special color has a relationship with the absorption bands at about 460 nm and 480 nm. Based on the CIE 1976 L*a*b* colour system, we come to the conclusion that both color coordinates a* and b* control the value of chroma C*, and color coordinate b* mostly controls the hue angle h°. We also explore how the different chromogenic ions FeOtot and MnO and their ratio FeOtot/MnO influence spessartines’ color, finding that the color of spessartine samples is influenced by both Mn and Fe. By analyzing the FTIR spectrum, we discovered that as the content of Mn decreases, and the A, C and D peaks move to the position of a longer wave, the color of spessartine samples also changes significantly. By using the standard light source D65, we find that N9.5 Neutral Grey Background is the best background to grade the color of spessartines.

Texto completoResumen
Following the work of Sharma et al. (1990) on the interference of ascorbic acid (AA) with starch-iodine reaction, the present authors repeated it, giving a proper explanation of the influence of AA in this reaction. AA oxidizes iodine-iodide (I-KI) reagent which makes impossible to form the blue complex with starch. Three measures are suggested to overcome the interference of AA: 1) to titrate starch solution with I-KI reagent and thus work out an I-KI amount for development of blue coloration, 2) to remove from plant material AA (and other reducing soluble substances) by washing the material with cold water or ethanol, and 3) starch solution could be treated with alkali (pH about 9), which destroys AA in 15 minutes. After acidifying the solution and adding I-KI reagent the blue complex can be determined.

Xenodacnis is a specialized high Andean bird genus of which males are larger and show different feather coloration from females. However, sexual dimorphism has not been analyzed in detail yet. Distributed in Ecuador and Peru, Xenodacnis have long been considered as a single species genus, with three subspecies. Discovered in the 1980`s, the population in Ecuador has not been given a taxonomic identity so far. Thus, this study gathers morphological data from Xenodacnis throughout its distribution, and confirmed the morphological differences between sexes: males are significantly larger and heavier than females; but without consistent differences in bill size. Between populations, the research shows smaller individuals in the south, with size increasing towards the northernmost Ecuadorian populations. These results suggest that the taxonomy of the genus Xenodacnis should be revised and the population from Ecuador should have a proper taxonomic identity different from all previously described members of the genus

Texto completoResumen
<p>The visual quality of ornamental plants is necessarily linked to an adequate balance of nutrients. Plant height, shape and coloration are qualitative aspects of ornamental species, directly influenced by mineral nutrition, among other environmental aspects. The nutritional requirements of ornamental species are not yet well established, often resulting in inefficient use of chemical and organic fertilizers, without respecting the needs of each species as well as the proper time for application. This leads to the low quality of the final product, as well as high production costs, which justifies the importance of a nutritional knowledge of the species. In addition to plant nutrients, some elements not considered essential, such as silicon, may provide improvements in the quality of certain species, including ornamental plants. In this sense, this paper aims to compile information on the use of nutrients for ornamental species in order to contribute to the knowledge of the principal aspects of plant quality as relates to mineral nutrition.</p>

Texto completoResumen
Établissement public à caractère industriel et commercial (EPIC), la RATP est dotée d’instances représentatives du personnel propres jusqu’aux ordonnances de 2017 qui marquent une rupture et la font entrer dans le droit commun. Cela n’entraîne toutefois ni une normalisation des instances qui sont structurées différemment du fait d’une dynamique sectorielle particulière ni une normalisation des pratiques de représentation du personnel qui demeurent marquées par la trajectoire historique des organisations syndicales et notamment leur densité. En effet, la transformation de l’EPIC en plusieurs sociétés anonymes dans le cadre de l’ouverture à la concurrence donne à la mise en place des CSE une coloration particulière puisqu’il s’agit d’anticiper une décentralisation des fonctions de direction à rebours de la centralisation généralement observée. En outre, dans un contexte où les organisations syndicales sont relativement développées, l’affaiblissement du pouvoir institutionnel lié à la mise en place du CSE à la RATP que nous constatons entraîne un report des stratégies syndicales sur le pouvoir organisationnel, ce qui se traduit par une certaine désinstitutionnalisation de la conflictualité.

Food waste generated by the lack of proper processing of fruit parts, such as peels and seeds, is a global problem, although these by-products could enrich the nutritional value of food products. Thus, this study aimed to develop, characterize, and perform a sensory analysis of functional muffins enriched with flour made from Dialium guianense and Nephelium lappaceum L. fruit peels. Four muffin formulations were developed with different substitution levels (0, 2.5, 5, and 7.5%) of wheat flour with the fruit peel flour. The muffins were analyzed for proximate composition, weight reduction, color, texture profile, sensory profile (color, odor, flavor, texture, and overall appearance), and purchase intention. The results showed that the formulations with flour produced from the fruit residues had higher fiber and lipid content, less weight loss during baking, and darker coloration than standard samples. The sample with 2.5% wheat flour replaced with fruit peel flour showed better sensory parameters and purchase intention. Hence, the physical, chemical, and sensory analyses presented a positive increase in the nutritional and sensory quality of the developed products.

Photonic crystals are periodic dielectric nanocomposites, which have photonic band gaps that forbid the propagation of light within certain frequency ranges. This property enables one to manipulate light with amazing facility. Such nanoarchitectures frequently occur in living organism like butterflies and beetles. Butterfly scales are particularly well suited to be used as optical gas sensors as their nanoarchitecture is an open sponge-like type, composed of chitin and air. The open nanoarchitecure allows fast gas exchange. The spectral change of the reflected light depends on the composition of the ambient atmosphere and also on the wing nanostructure. In this work we show the results of recent measurements on nine Polyommatine species with dorsal blue coloration. Their color is generated by similar pepper-pot type nanoarchitectures which exhibit species specific characteristics, associated with species specific color. Experiments were carried out changing the concentration and nature of test vapors while monitoring the spectral variations in time. Proper data processing results gas-selective and concentration dependent signals. Our work shows a way to a prospective integrated biological - optical sensor combining light-weight and low power consuming with environmental friendly production.

In the present work, we propose a new architecture for partly covered photoelectrochromic devices with a modified anode layout, so that the TiO2 film is deposited first on the substrate, covering a small part of its surface, followed by the WO3 film that covers the remaining device area. As a result, the TiO2 film can be subjected to the proper thermal and chemical treatment without affecting the electrochromic performance of the WO3 film. The proposed design led to photoelectrochromic (PEC) devices with a power conversion efficiency (PCE) four times higher than that of typical partly covered devices, with a measured maximum of 4.9%. This, in turn, enabled a reduction in the total area covered by the photovoltaic unit of the devices by four times (to 5% from 20%), thus reducing its visual obstruction, without affecting the depth, uniformity and speed of coloration. A detailed study of the parameters affecting the performance of the new devices revealed that, with the cover ratio decreasing, PCE was increasing. The photocoloration efficiency also exhibited the same trend for cover ratio values below 15%. Storage of the devices in short circuit conditions was found to accelerate optical reversibility without affecting their photovoltaic and optical performance.

BACKGROUND: The upper limb plays a vital role in our daily function; injuries to this vital structure can result in devastating consequences to functional, psychological and social well-being; especially traumatic amputations of the upper limb are challenging to manage and deciding which patients would benefit from limb salvage versus amputation is critical. CASE REPORTS: A 52-year-old male patient, who suffered a traumatic partial amputation in the distal third of his right forearm with an industrial machine, presenting an ulnar and radius fracture, with severe soft tissue injuries, who underwent a replantation surgery after 12 hours of ischemia. EVOLUTION: Patient presented good postsurgical outcome. 24 hours after surgery he presented normal Allen’s test results, adequate temperature, pink coloration, hypoesthesia and 2/5 muscle strength in the injured limb. He was discharged 7 days after surgery with follow-up and rehabilitation prescription. The percutaneous needles were removed 13 weeks after, with proper bone healing of the fracture. 5 months after surgery, he presented a DASH Score of 60.83. CONCLUSION: The replantation field has become very sophisticated in recent years; the decision to perform replantation of the amputated limb must be individualized to each patient, based on several established factors such as the characteristics of the injury, patient related factors, and the functional recovery capacity.

Naturally brown colored cotton (NBCC) is becoming increasingly popular due to its natural properties of coloration. However, poor fiber quality and color fading are key issues that are hindering the cultivation of naturally colored cotton. In this study, based on transcriptome and metabolome of 18 days post-anthesis (DPA), we compared the variations of pigment formation in two brown cotton fibers (DCF and LCF), with white cotton fiber (WCF) belonging to a near-isogenic line. A transcriptome study revealed a total of 15,785 differentially expressed genes significantly enriched in the flavonoid biosynthesis pathway. Furthermore, for flavonoid biosynthesis-related genes, such as flavonoid 3′5′-hydroxylase (F3′5′H), anthocyanidin synthase (ANS), anthocyanidin reductase (ANR), chalcone synthase (CHS), dihydroflavonol 4-reductase (DFR), and chalcone isomerase (CHI), their expressions significantly increased in LCF compared with DCF and WCF. Moreover, transcription factors MYB and bHLH were significantly expressed in LCF and DCF. Most flavonoid-related metabolites (myricetin naringenin, catechin, epicatechin-epiafzelechin, and epigallocatechin) were found to be more highly up-regulated in LCF and DCF than WCF. These findings reveal the regulatory mechanism controlling different brown pigmentation in cotton fibers and elucidate the need for the proper selection of high-quality brown cotton fiber breeding lines for promising fiber quality and durable brown color pigmentation.

Currently many works of art made of soapstone and recognized as cultural patrimony of humanity are in an advanced stage of degradation. Hence, it is necessary to interrupt this process and recover the deteriorated parts. Composite materials consisted of steatite particles and epoxy polymer are designed and characterised for their application in the repair of sculptures made of soapstone. The material applied in restorations should provide coloration and texture similar to soapstone besides structural requirements. The degree of similarity of the artificial material to the rock is enhanced by the proper selection of the particle size range and the increase of steatite incorporation in the composites. A statistical methodology based on the mixture design is used to optimize the relative amount of three particle size fractions of steatite particles in order to maximise the proportion of the dispersed phase in the composites. The maximum particle packing density (1.50 g/cm³) is obtained for a ternary mixture, composed of 62% of coarse particles (1.18 mm - 0.60 mm), 6% of medium sized particles (0.60 mm - 0.30 mm) and 32% of fine particles (0.30 mm - 0.15 mm). In this manner, the fabrication of composites based on an epoxy polymer matrix with 70wt% of incorporated steatite particles has been possible, increasing the maximum amount by 10% as used in previous works.

Texto completoResumen
The process of nuclear condensation is an integral part of erythroid differentiation. We have previously shown that loss of the histone methyltransferase, Setd8, results in severe embryonic (primitive) erythroid anemia due to loss of chromatin condensation and proper erythroid terminal maturation (Malik 2017). Setd8 mediated H4K20 mono-methylation is an important mediator of higher order chromatin condensation and can recruit members of the Condensin II complex (Lau 2015). ondensin I and II complexes are five protein, large complexes responsible for DNA organization and packaging during mitosis. In eukaryotes, the complexes are composed of conserved SMC components, with each Condensin having a unique kleisin bridge protein and two HEAT subunits. Subunits of Condensin II are highly expressed in erythroid cells, suggesting an erythroid specific function. Overexpression of the Condensin II HEAT subunit, Cap-G2, accelerates erythroid differentiation in MEL cells (Xu 2006). To interrogate the role of Condensin II in a primary model, we mated endogenous EpoR driven cre expressing mice with mice containing a floxed allele around Condensin II kleisin subunit, NcapH2. Embryos homozygous for EpoR specific excision of NcapH2 suffered from severe primitive erythroid anemia with visible anemia beginning at embryonic day (E11.5) and lethality occurring at approximately E13.5. Peripheral blood analysis at E11.5 was significant for erythroblasts with enlarged cell size and nuclear size, as well erythroblasts with dysplastic appearing nuclei. Knockout embryos at E12.5 exhibited peripheral blood anemia, with an increase in the number of dysplastic appearing cells, and decreased fetal liver coloration suggesting a failure of both primitive and fetal definitive erythropoiesis. Failure of the embryonic erythroid lineage to expand was confirmed in a primary cell culture system in which loss of proliferation was limited to mid to late stage precursors, suggesting that Condensin II function is critical beyond the proerythroblast stage of maturation when nuclear condensation is occurring and mass spectrometry demonstrates that H4K20 mono-methylation accumulates. Characterization of primitive erythroblasts from knockout embryos showed increased cell size, increased scatter in the size of the nucleus, and a high frequency of cells with punctate nuclear staining. In addition, the subset of erythroid cells with punctate nuclei did not appear to have a nuclear envelope, suggesting a pre-mitotic error, likely during G2 of the cell cycle. Indeed, knockout cells showed a buildup of cells in G0-G1 of the cell cycle, suggesting arrest following a defective cell division. Together, our data suggests that Condensin II is required during erythroid maturation for proper cell cycle progression and chromatin organization, and that chromatin modifications, such H4K20me1, may be a required mechanism to control the higher-level organization of chromatin. This control is required in red cell precursors, as they undergo rapid expansion, maturation, and nuclear condensation simultaneously. Understanding these mechanisms will give valuable insight into the unique sensitivity of red cells to chromatin perturbations observed in bone marrow failure and myelodysplastic syndromes.

The textile industry is one of the largest water-consuming industries in the world. The wastewater generated by the textile industry is a major source of pollution, containing mostly dyes, but also detergents, and heavy metals. Since dyes can have a negative impact on the environment, human and aquatic life, it is really important to find proper solutions for removal of these pollutants from wastewater. In addition, special attention is given to the discovery of new and fast "in situ" methods for identification and quantification of pollutants from wastewater. In this paper, SBA-15, mesoporous silica material, was used as sorbent for removal of Basic Yellow 28 from aqueous solutions. In addition, colored SBA-15 after sorption process was subjected to image analysis, to evaluate if it was possible to quantify sorbed dye on sorbent based on intensity of SBA-15 coloration. The obtained results revealed that SBA-15 could remove 99% of dye within 5 min. The highest efficiency of dye removal was at pH8, using 200 mg of sorbent. According to the Langmuir isotherm model, the theoretical maximum sorption capacity was 909 mg/g. Image-Pro software confirmed that it would be possible to quantify sorbed dye onto SBA-15 with accuracy of 0.98. Overall, SBA-15 demonstrated to be efficient sorbent in removal of Basic Yellow 28 from water, but also to be potential carrier as a sensor for detection of colored pollutants in water.

Myoepitheliomas account for approximately 1.5% of all salivary gland tumors and arise most frequently from the parotid gland. Recently, a new myoepithelioma variant, called mucinous myoepithelioma, has attracted widespread attention. These tumors are recognized as a unique subtype of myoepithelioma, characterized by the presence of abundant mucin. We herein report the findings of an 86-year-old Japanese woman who presented with a hard mass of the right parotid gland behind her right ear which was gradually increasing in size. The patient had undergone a fine-needle aspiration biopsy 4 years earlier, and a cytological evaluation of a biopsy specimen had shown features of pleomorphic adenoma. A resection was thus performed and the tissue was found to be an encapsulated, soft and solid mass, and the cut surface was observed to be a capsulated and well-defined tumor lesion with myxoid-looking foci of gray-white coloration. Microscopic examination revealed that this lesion was composed of a proliferation of bland-looking epithelial and myoepithelial cells, arranged in a solid or reticular growth fashion in an abundant myxomatous or hyalinized stroma. These neoplastic epithelial cells had centrally located small nuclei with fine chromatin and abundant clear to eosinophilic cytoplasm, often containing mucin in a uniform pattern. Immunohistochemical staining demonstrated the tumor cells to be positive for AE1/AE3, S-100 and mucicarmine. Our findings suggest this case to be one myoepithelioma variant of mucinous myoepithelioma, and more experience related to this myoepithelioma variant is necessary to better understand its biological behavior and make an accurate diagnosis for a proper treatment.

Texto completoResumen
Anablepsoides hartii is a non-annual fish of the family Cynolebiidae. Historically, this species has presented some inconsistencies for proper identification, due to a variation in the color pattern. The aim of this study was to describe and illustrate the different types of color patterns found in this species. For this purpose, we examined a total of 336 preserved specimens (19 lots) deposited in the ichthyological collections of the Museo de Biologia de la Universidad Central de Venezuela and the Museo de Ciencias Naturales in Guanare, Venezuela. The specimens were sorted by distinctive characteristics of size, sex and locality. Besides, we took photographs of each individual, vectorized them with detail, separating light and dark colorations and delimited color patterns of the same tone with the program Corel Draw version x7 (Spanish). My analysis showed that A. hartii presented four colors patterns. The color morphs were classified as: 1 male, 2 female, 3 intermediate and 4 montane. The first two color morphs were separated by sexual characters (sexual dimorphism); in turn, the intermediate color morph presented characters of both males and females in the same individual. Finally, the montane color morph differed from the previous ones by presenting a series of incomplete lateral rows, followed by a half-body reticulation to the tail.

Texto completoResumen
This study reports on sudden death (or decline) of mature and apparently healthy pecan trees [Carya illinoinensis (Wangenh.) K. Koch]. Observations suggest that death and damage is due to winter cold injury (although the season's low was only -5 °C). The severity of this cold injury-like form of sudden death is closely associated with nut crop load (i.e., grams of kernels per square centimeter of trunk cross-sectional area) and premature defoliation. Both dead and declining trees not only produced relatively heavy crops, but also exhibited substantial premature pest-induced defoliation the previous autumn. The near absence of sugars and starch in roots and shoots of dead or declining trees at budbreak and the relatively high levels in healthy trees indicates that diminished assimilate reserves during the dormant season were the key factor causing death or decline. The diminished assimilate reserves prevented the accumulation of assimilate reserves necessary for maintaining live roots throughout the dormancy and prevented proper cold acclimation of shoot tissues. Distinct symptoms of sudden tree death or decline compared to typical cold damage are: a) a distinct top-to-bottom gradation of tree damage, with an increased proportion of dead shoots and shoots supporting abnormally small foliage being near the base of the canopy; b) dessicated and tan appearance of inner bark and phloem of the main trunk rather than brown coloration so typical of classical cold injury; c) death of roots by time of budbreak; and d) absence of resprouting from the trunk or root collar. These observations indicate that pecan trees can suddenly die due to being overly stressed for assimilates and that economic losses previously attributed to injury by severe winter cold sometimes may be due to depleted assimilate reserves during the dormant season as a result of overcropping and premature defoliation.

Mycenaean vitreous artifacts, such as beads and relief plaques, are highly susceptible to degradation, which can significantly alter their visual characteristics and pose challenges to their taxonomy. The visual manifestation of corrosion on vitreous artifacts, especially glass and faience, has often led to their misclassification, which, in turn, has a significant impact on their interpretation by researchers, often resulting in misleading notions. The present paper constitutes part of an overall study, implemented within the framework of the project, Myc-MVP: Mycenaean Vitreous Production, A Novel Interdisciplinary Approach Towards Resolving Critical Taxonomy Issues, which has employed a combination of established, state-of-the-art scientific methods to analyze and identify the specific compositional changes occurring at different spatial dimensions within surface layers, with the overarching aim of contributing to our understanding of the degradation mechanisms of vitreous artifacts and the relevant implications for the archaeological record. Importantly, these findings will yield useful data in devising strategies for the proper classification, management, and preservation of vitreous artifacts in the future. The present study focuses on investigating the relationship between the compositional changes in a subset of 12 (of the overall 126 objects entailed in the project) corroded vitreous artifacts from Mycenaean contexts in the Aegean and the way these are manifested visually, with the application of X-ray fluorescence and LED microscopy. We aim to decipher the nature of corroded objects with the aid of focused analysis. This study delves into degradation processes in glass artifacts, highlighting preservation variations and environmental influences like burial. Coloration, attributed to copper and cobalt oxide, shows some correlation with preservation quality. These chromophore agents potentially induce thermal stresses and corrosion. The complex interplay between chemical composition, environmental conditions, and preservation status underscores the need for comprehensive research. Analyzing the full artifact set using complementary techniques promises deeper insights for secure material classification and cultural heritage preservation.

Nitrogen (N) is one of the promising nutrients for lawn growth and is required for the lawn’s proper growth and development, but it also increases mowing frequency. Glyphosate herbicide application in sub-doses, as a growth regulator, can reduce the maintenance costs without any adverse reduction in the density and nutritional status of grasses. The objective of this study was to evaluate the influences of nitrogen and glyphosate doses on the growth, aesthetic quality and nutritional status of emerald grass (Zoysia japonica Steud.). The experiment was conducted at the Research and Extension Education Farm of São Paulo State University (UNESP), Ilha Solteira, SP, Brazil, in an Ultisol. The experiment was designed as a randomized block with 12 treatments arranged in a 3 × 4 factorial scheme with 4 replications, comprised of a control (without N), 15 and 30 g N m−2 of urea, applied in five splits annually, and glyphosate doses (0, 200, 400 and 600 g ha−1 of the active ingredient, a.i.). The split N fertilization at the rate of 15 g m−2 and glyphosate at the dose of 400 g ha−1 maintained nutritional status of emerald grass. Nitrogen at the rate 15 g N m−2 (in five splits per year) was observed to produce lower growth traits, an adequate aesthetic quality and longer stability of the nutrients in emerald grasses through lower exportation, with removal of “clipping” after mowing. In addition, glyphosate, at the dose of 400 g a.i. ha−1, was efficient in reducing the leaf area, plant height, shoot dry matter and total dry matter by 18.3, 14.7, 6.8 and 8.1%, respectively, as compared to the control. However, this dose did not impair the coloration and resulted in a lower exportation of nutrients by reducing the need to replenish by fertilization. Therefore, fertilization with 15 g N m−2, associated with application of 400 g a.i. ha−1 of glyphosate, is recommended for emerald grass in the tropical savannah of Brazil.

Texto completoResumen
The American red flat bark beetle, Cucujus clavipes, is a wide distributed saproxylic species divided into two subspecies: ssp. clavipes restricted to eastern regions of North America and ssp. puniceus occurring only in western regions of this continent. Unique morphological features, including body shape and body coloration, make this species easy to recognize even for amateurs. Surprisingly, except some studies focused on physiological adaptations of the species, the ecology of C. clavipes was almost unstudied. Based on over 500 records collected by citizen scientists and deposited in the iNaturalist data base, we studied phenological activity of adult beetles, habitat preferences and impact of future climate change for both subspecies separately. The results clearly show that spp. clavipes and ssp. puniceus can be characterized by differences in phenology and macrohabitat preferences, and their ranges do not overlap at any point. Spp. clavipes is found as more opportunistic taxon occurring in different forests as well as in urban and agricultural areas with tree vegetation always in elevations below 500 m, while elevational distribution of ssp. puniceus covers areas up to 2300 m, and the beetle was observed mainly in forested areas. Moreover, we expect that climate warming will have negative influence on both subspecies with the possible loss of proper niches at level even up to 47–70% of their actual ranges during next few decades. As the species is actually recognized as unthreatened and always co-occurs with many other species, we suggest, because of its expected future habitat loss, to pay more attention to conservationists for possible negative changes in saproxylic insects and/or forest fauna in North America. In addition, as our results clearly show that both subspecies of C. clavipes differ ecologically, which strongly supports earlier significant morphological and physiological differences noted between them, we suggest that their taxonomical status should be verified by molecular data, because very probably they represent separate species.

BACKGROUND: Peritonitis is the most common infectious complication of peritoneal dialysis (PD) with an estimated ratio of 1:20–30 patients per month. In addition, less than 3% cases are due to Mycobacteria, although not all are caused by Mycobacteria tuberculosis. Therefore, specific examinations are needed for proper diagnosis. Encapsulating peritoneal sclerosis (EPS), another rare complication of PD, accounts for 0.7–13.6 per 1000 patients per year. CASE REPORT: A 37-year-old man undergoing PD, with complaints of intermittent abdominal pain and cloudy fluid, followed by nausea, vomiting, and constipation. Furthermore, visible protrusion was observed on the abdominal wall due to the wound from the Tenckhoff catheter insertion surgery. This is clearly comprehended as the patient sits or stands but disappears on lying down. Along with the condition, continuous ambulatory PD (CAPD) ultrafiltration ability decreases, rough defecation occurs, with a hard sensation on the lower right abdomen. Moreover, the patient had earlier suffered peritonitis for the 3rd time. The results of the dialysate fluid analysis showed a cloudy liquid coloration, as the number of cells 278, polymorphonuclear 87, mononuclear 13, Ziehl–Neelsen +1 and acid-resistant bacteria +3 staining, including GeneXpert MTB/RIF, were positive. Furthermore, abdominal computed tomography (CT) scan revealed a thick peritoneum, partly with calcification, air-filled intestinal, dilated colon with wall thickening. Furthermore, the mesentery lining the liver and intestine were observed to be dense with multiple calcifications to support an EPS. Definitive diagnosis is confirmed by laparotomy and/or laparoscopy, but CT scan provides an alternative. Subsequently, CAPD utilization is discontinued and switched to renal replacement therapy to hemodialysis twice a week due to several complications associated with PD, ranging from recurrent peritonitis, tuberculous peritonitis, EPS, and incisional hernias responsible for an ineffective PD ultrafiltration. CONCLUSION: At present, the combination of clinical symptoms, radiology, and medical pathology remains the key to diagnosing tuberculous peritonitis and EPS. Consequently, prompt and precise analysis determines a good prognosis.

Texto completoResumen
Background. In developing countries, intestinal parasitic infections (IPIs) and tuberculosis (TB) coinfections have been perceived to be high. The geographic distributions of helminths and TB overlap substantially. Parasitic infections affect the outcome of TB by changing the cell-mediated immune response to a humoral response, while Mycobacterium infection favors the immune escape of helminths. There are limited studies on the epidemiology of intestinal parasites among presumptive pulmonary TB (PTB) patients in Ethiopia. Therefore, this study is aimed at determining the prevalence of intestinal parasitic infections and associated factors among patients with presumptive pulmonary tuberculosis at Debre Tabor Referral Hospital. Methods and Materials. A hospital-based cross-sectional study was conducted from March to June 2021. The sociodemographic data and associated factors were collected using a structured questionnaire, and stool samples were collected by convenient sampling technique and processed for the detection of intestinal parasites using a direct wet mount saline preparation and formal ether concentration technique. The data was coded, cleaned, and analyzed by SPSS version 23. Bivariate and multivariable analyses were conducted to determine an adjusted odds ratio (AOR). p value < 0.05 was considered statistically significant. Result. The overall prevalence of intestinal parasitosis was 25.6% (81/316); of these, 12.9% (41/316) were protozoan infections and 12.7% (40/316) were helminth infections. Multivariable logistic regression analysis showed that being older than 36 years (AOR: 4.35; 95% CI: 1.26, 13.91; p=0.001), rural residence (AOR: 3.46; 95% CI: 1.18, 9.97; p<0.001), unable to read and write (AOR=2.62; 95%CI=2.15,8.43; p=0.004), and use of river water (AOR: 3.47; 95% CI: 1.62, 8.21; p<0.001) were associated with intestinal parasitic infections. Conclusion. The present study showed that the prevalence of intestinal parasitosis among presumptive pulmonary tuberculosis patients was high in the study area. Age, residence, educational status, and source of water were significant factors in IPIs among presumptive TB patients. Moreover, our findings suggest a proper health education program for good personal hygiene habits, the coloration of water, avoiding open-field defecation, and also preventative measures to avoid the acquisition of IPIs in patients with TB. Presumptive tuberculosis patients should be screened and treated accordingly. Additionally, it needs further research and recommends more assessment for intestinal parasitic infection in PTB patients.

Texto completoResumen
Unconventional production techniques became interesting and promising part of manufacturing methods. They provide complementary, to traditional loss methods, solutions enabling use of high - performance engineering materials for construction of machinery and industrial equipment. By using properly selected methods or their hybrids difficult to cut materials as steel, alloys, sintered materials and composites can be processed. Among the wide variety of unconventional methods of materials forming, particular attention should be given to electrochemical machining, which has been successfully used in various industries. This fact proves attractiveness and versatility of ECM. The method could be used on large scale and many variations was developed as each application requires an individual approach and has own requirements. One of the least known and described type of electrochemical machining is jet ECM where the electrolyte jet stream acts as a tool. In this kind of machining, the part is shaped only in the area where the electrolyte jet strikes the surface. This is due to the fact that the current density distribution is located just below the stream. In the area around the jet hitting the work piece thin electrolyte layer is formed. Thickness of that layer is growing rapidly. Since the electrolyte jet machining is an electrochemical process, the machined surface has all the benefits of ECM. There is no burrs and low temperature of the process prevents appearance of cracks and there is no heat-affected zone. Electrolyte jet machining can be used as well as in macro and micro drilling, turning, texturing, and electroplating. The process can be controlled by proper selection of such parameters as time, the current density and the diameter of the jet. Jet ECM can be used not only for material removal, but also for coloration (passivation) by means of anodic dissolution. 3D shaping of elements is also possible by controlling the current and the velocity of the electrolyte stream. In addition, by changing the polarity of the applied voltage it is possible to use this method in broadly considered electroplating. The paper presents results of the initial research on jet electrochemical machining (jet ECM) of acid proof steel and tungsten carbide. The material processing was carried in two ways – drilling holes and shaping grooves. Shaping was realized in milling and face turning regime. The influence of the two basic process parameters voltage and pressure was examined. In order to get rough information about the jet ECM process experiment planning method was applied. Obtained results enable planning of the further extended research.

Texto completoResumen
New eco-ethological data on the Anadyr stock of beluga whales are presented based on 14-year (2000-2013) studies by methods of satellite tracking telemetry, multi-spectral aerial surveys and genetic analysis, as well as traditional and ecosystem-based approaches. Possible factors of the separate stock formation in the Anadyr Gulf are discussed, as geographic isolation, environmental conditions, foraging resources, elimination of the beluga whales, and biological isolation (on the results of genetic analysis). The beluga whales are well-adapted to oceanographic conditions and ice regime of the Arctic waters that is realized in their relationship with edge of the sea ice, ability to live in both salt and fresh waters (they enter rivers), and versatility in feeding. Their ice-associating, high sociality, and white protective coloration provide protection against killer whales and other predators and their eury-halinity allows to expand the feeding grounds both to the sea and rivers and hunt for both freshwater, anadromous and marine prey. The food spectrum of beluga whales in the Anadyr estuary is very wide and includes 12 fish species and 1 crustacean species. In the summer-autumn season, the salmons are the most significant part of the diet, as chum salmon Oncorhynchus keta , pink salmon O. gorbuscha and arctic char Salvelinus malma , whereas arctic smelt Osmerus mordax dentex , saffron cod Eleginus gracilis , sculpins Cottidae sp., anadyr whitefish Coregonus anaulorum , and siberian whitefish Coregonus sardinella are presented in the diet to a lesser extent. There is supposed on the base of episodic net surveys, that the beluga whales feeding in marine areas is more diverse, and the most important their prey in the sea are walleye pollock Theragra chalcogramma , pacific cod Gadus macrocephalus , flounders Pleuronectidae sp., sculpins Cottidae sp., capelin Mallotus villosus catervarius , polar cod Boreogadus saida , halibuts Pleuronectidae sp., stingrays Bathyraja , herring Clupeidae sp., and several species of decapod crustaceans Hyppolitidae sp. and Lithodidae sp. Natural enemies of beluga whales are killer whale Orcinus orca , polar bear Ursus maritimus , and predatory form of pacific walrus Odobenus rosmarus . Rather large number of beluga whales are eliminated by the sea ice, up to 80 animals annually, that exceeds in several times the aboriginal landings in Chukotka. Parasitic fauna of the beluga whale is still unclear and requires special investigations; the cases of epizooty are unknown in the Anadyr Gulf. Philopatry is proper to the Anadyr beluga whales, with preference of the Anadyr estuary and the Anadyr Gulf as their habitats, that is explained by optimal for them environments and high food capacity. Unique adaptation of beluga whales to the environments of the Anadyr estuary is their ultrasonic vocalization in the high-turbidity waters. Genetic analysis shows a differentiated distribution of the beluga whales haplotypes in different areas of the North Pacific, so the stock of the Anadyr Gulf is significantly isolated in the post-glacial times. Low anthropogenic pressure on beluga whales in the Anadyr Gulf allows them to maintain their stock there.

ABSTRACT: The somatic cell count (SCC) is a diagnostic tool that indicates the mammary gland health and can be determined by the counting of cells in the microscope. There are discussions regarding appropriate staining method to the ewes’ milk. The present study aimed to identify a methodology of microscopic SCC proper to the milk of the ovine species. Therefore, glass slides for smear were manufactured with 10 µL of ewe’s milk in 1 cm2, and the fixers xylol and Carnoy’s solution were tested, as well as and May-Grünwald, Broadhurst-Paley, Wrigth and Panoptic stainings. Carnoy’s solution was elected, because it allowed a better fixation of the dairy film to the microscope slides, and Broadhurst-Paley staining, due to its good coloration and visualization of cells, as well as the differentiation of cytoplasmic corpuscles in ewe’s milk. Broadhurst-Paley coloration is a tool applicable to the somatic cell count in ovine specie’s milk.

Abstract Lesions in the oral cavity of dogs can be erythematous, leukoplakic, or pigmented in coloration. The diagnosis of oral erosions, ulcers, and white lesions in contrast to pigmented lesions in veterinary practice can be challenging. The most benign-looking oral ulcers can be associated with local malignant or systemic disease. Many factors are important in the evaluation and correct diagnosis of oral lesions, including medical and drug history, description of the lesion, number of lesions, depth of the lesion, biopsy technique, and correct histologic interpretation. The goal of this paper is to create a decision tree to guide the classification and proper diagnosis of canine oral mucosal lesions.

AbstractFor the first time, Piscicola brylinskae was described from Lake Vechten in the village of Bunnik, near Utrecht — The Netherlands. Until now, P. brylinskae has been found in Poland in Lake Maróz and in the Łyna River near Olsztyn (the northern part of Warmian-Masurian voivodeship). Thanks to proper conservation the coloration of P. brylinskae was described for the first time. Applying 32 indexes resulted that P. brylinskae clustered to Caspiobdella fadejewi. Analysis based on 113 non-metric characteristics has shown that P. brylinskae is most similar to Piscicola margaritae. Though, P. brylinskae do not form with P. margaritae dichotomic branching nor with any other species from this cluster, it could confirm that it is an individual species of the Piscicola genus.

It is clear that the realization and attainment of educational goals and objectives largely depend on the extent to which government policies can give educational inputs adequate attention needed. Proper educational inputs will no doubt bring about a conducive learning environment that is safe for students and teachers as well as enhances the quality of instruction which will, in turn, promote effective teaching and learning process. No doubt, Nigeria is facing many challenges in the education sector, which are majorly attributed to the political interplay regarding the administration of educational inputs. This political interplay influences the politics in the administration of the fund, students’ enrollment, availability and utilization of school plants, and the number of educational facilities and equipment needed for effective teaching-learning processes. Observation has shown that Nigerian educational inputs are not properly managed due to political inclinations with different ideologies and policies. Hence educational inputs lack the proper administration. Because of this, teaching and learning processes are unconducive for both teachers and students. Therefore, this study examined the monumental political challenges, among other challenges confronting the administration of educational inputs in Nigeria. The study used primary and secondary data to gather information for the study. It was revealed that funding, corruption, and cultural and manpower problems, among others, were the political challenges confronting the administration of educational inputs in Nigeria. The study concluded that government should create enabling environment void of any political coloration by making realistic and achievable policies for schools to thrive.

Texto completoResumen
Currently many works of art made of soapstone and recognized as cultural patrimony of humanity are in an advanced stage of degradation. Hence, it is necessary to interrupt this process and recover the deteriorated parts. Composite materials consisted of steatite particles and epoxy polymer are designed and characterised for their application in the repair of sculptures made of soapstone. The material applied in restorations should provide coloration and texture similar to soapstone besides structural requirements. The degree of similarity of the artificial material to the rock is enhanced by the proper selection of the particle size range and the increase of steatite incorporation in the composites. A statistical methodology based on the mixture design is used to optimize the relative amount of three particle size fractions of steatite particles in order to maximise the proportion of the dispersed phase in the composites. The maximum particle packing density (1.50 g/cm³) is obtained for a ternary mixture, composed of 62% of coarse particles (1.18 mm - 0.60 mm), 6% of medium sized particles (0.60 mm - 0.30 mm) and 32% of fine particles (0.30 mm - 0.15 mm). In this manner, the fabrication of composites based on an epoxy polymer matrix with 70wt% of incorporated steatite particles has been possible, increasing the maximum amount by 10% as used in previous works.

The study was conducted on the Danube River, within the project Joint Danube Survey 3 (JDS3). The main aim was to estimate the quantity of microplastics in aquatic ecosystems through passive biological monitoring. Three freshwater species were used for microplastic (MP) isolation from different taxonomic groups of organisms: Mollusca, Oligochaeta, and Chironomidae (Diptera), with the following species: Lithoglyphus naticoides (C. Pfeiffer, 1828), Limnodrilus hoffmeisteri (Claparede, 1862), and Chironomus acutiventris (Wülker, Ryser & Scholl, 1983), respectively. The samples were collected from 6 sites along the Danube River where 540 specimens were examined. The samples were digested by alkaline method (incubation in 10% KOH solution at 60 ⁰C for 24 h) and filtered through a mill silk, 10 µm mesh size. Collected particles were categorized as: fibre, hard plastic, nylon, rubber, or miscellaneous. Categories were divided into subcategories based on the coloration of the particles. Particles ingested by organisms were represented mostly by fibres and fragmented hard plastics, within the size range were from 0.03 to 4.87 mm. A total of 678 MP particles were collected with an average of 4.64 ± 1.59; 1.64 ± 0.46 and 1.24 ± 0.34 items/organism isolated from L. hoffmeisteri, L. naticoides and C. acutiventris, respectively. According to results, L. hoffmeisteri, L. naticoides and C. acutiventris could be used as proper bioaccumulators of MP pollution in the Danube River.

Three freshwater species were used for microplastic (MP) isolation from different taxonomic groups of organisms: Mollusca, Oligochaeta, and Chironomidae (Diptera), with the following species: Lithoglyphus naticoides (C. Pfeiffer, 1828), Limnodrilus hoffmeisteri (Claparede, 1862), and Chironomus acutiventris (Wülker, Ryser & Scholl, 1983), respectively. The samples were collected from 6 sites along the Danube River where 540 specimens were examined. The samples were digested by alkaline method (incubation in 10% KOH solution at 60 ⁰C for 24 h) and filtered through a mill silk, 10 µm mesh size. Collected particles were categorized as: fibre, hard plastic, nylon, rubber, or miscellaneous. Categories were divided into subcategories based on the coloration of the particles. Particles ingested by organisms were represented mostly by fibres and fragmented hard plastics, within the size range were from 0.03 to 4.87 mm. A total of 678 MP particles were collected with an average of 4.64 ± 1.59; 1.64 ± 0.46 and 1.24 ± 0.34 items/organism isolated from L. hoffmeisteri, L. naticoides and C. acutiventris, respectively. According to results, L. hoffmeisteri, L. naticoides and C. acutiventris could be used as proper bioaccumulators of MP pollution in the Danube River.

Achieving proper dispersion of pigments, dyes, or other additives, such as microcapsules or nanoparticles, within printing pastes or textile coatings is crucial for obtaining a homogeneous result. In certain specialized applications, such as coloration technology, it is possible to use colorimetry tools, visual examination, and even artificial vision to identify defects. However, none of these techniques comprehensively map the specific additive distribution. This paper proposes a novel approach: monitoring the distribution of conductive particles (graphene nanoplatelets, referred to as GNPs) within an acrylic coating paste using the Joule’s effect. Four different dispersion systems (ultrasound mixer, blender, toroidal agitation, and three-roll mill) are employed. Thermographic images provide an accurate view of how conductive particles are distributed. This complements data from numerical values, such as the maximum and average temperatures recorded for each sample. In certain cases, relying solely on numerical values can be inadequate or insufficient, hence the novelty of this article emphasizing the significance of using the Joule’s effect to assess the distribution of conductive particles. Concerning the mixing systems, optimal dispersion of GNPs in distilled water is most effectively achieved using an ultrasound mixer, with enhanced uniformity as dispersion time increases. For mixing the components of the coating paste, the toroidal agitation method yields the best result. Employing the three-roll mill is discouraged for this application due to its propensity to induce phase separation.

Texto completoResumen
Actinopyga echinites (Jaeger, 1833) is among the most exploited holothurians for exports in the Philippines. Despite its economic significance, the lack of management initiatives resulted in declining wild stocks. This study provides information on external morphology and biometric characteristics like length-weight relationship and condition factor of A. echinites for proper management and sustainability. The study was conducted conducted in dry (March to May 2021) and wet (June to August 2021) seasons in Cabgan Island, Barobo, Surigao del Sur, where two stations with three plots (10 × 10m) were laid as monitoring stations. The results revealed that A. echinites showed coloration and shape variation to adapt to their environment. Higher mean length (7.7cm) and significantly higher mean weight (41.5g) were observed in A. echinites in Station 2 than the ones in Station 1 (p < 0.05). Both stations had a higher length (7.8cm and 8.4cm) and weight (38.4g and 49.7g) during wet than dry months, but only Station 2 showed significant differences for the two parameters. The population showed a negative allometric growth resulting in its leaner shape, with the slope of regression lines being 1.89 and 1.82 in Station 1 and 1.75 and 1.97 in Station 2 for the dry and wet months, respectively. Both stations recorded high condition factors but significantly higher during the wet season (p < 0.05). Further study on the reproductive biology and environmental characteristics is needed to enhance scientifically sound management interventions for the conservation and sustainability of A. echinites populations.

Plants often express deficiencies with visible abnormalities; however, it is necessary to obtain reliable information to make the proper diagnosis about the missing nutrients. Until now, research with this approach has not been carried out for crops such as feijoa (or pineapple guava). For this reason, the present investigation identified and described the symptoms produced in young feijoa plants due to poor fertilization of N, P, and K and its effect on some components of plant growth and development. To achieve this, different treatments were established: complete fertilization (control); complete fertilization -N; complete fertilization -P; complete fertilization -K; and one treatment with no element (negative control, H2O). We determined the symptoms associated with each deficiency by means of a photographic record and the description of the symptoms. Among these nutrients, N deficiency yielded the highest plant detriment, due to lower growth and a global pale green coloration, while -P plants showed foliar malformations and necrosis, -K plants exhibited the brown margin in old leaves, then turning necrotic, while young leaves showed a lack of turgor. Also, lack of N seriously affected apical growth, number of basal and apical shoots, and chlorophyll foliar content, while the -P and -K developed lower growth rate in the shoot than in the control. Such symptoms were registered after two months of treatment. This study indicated that the greatest affectation of the feijoa was due to a lack of nitrogen; and also P and K deficiencies showed symptoms and growth characteristics that were altered in the development of the plants.

Texto completoResumen
A colouring of a $4$-cycle system $(V,{\cal B})$ is a surjective mapping $\phi : V \rightarrow \Gamma$. The elements of $\Gamma$ are colours. If $|\Gamma|=m$, we have an $m$-colouring of $(V,{\cal B})$. For every $B\in{\cal B}$, let $\phi(B)=\{\phi(x) | x\in B\}$. There are seven distinct colouring patterns in which a $4$-cycle can be coloured: type $a$ (${\times}{\times}{\times}{\times}$, monochromatic), type $b$ (${\times}{\times}{\times}{\square}$, two-coloured of pattern $3+1$), type $c$ (${\times}{\times}{\square}{\square}$, two-coloured of pattern $2+2$), type $d$ (${\times}{\square}{\times}{\square}$, mixed two-colored), type $e$ (${\times}{\times}{\square}{\triangle}$, three-coloured of pattern $2+1+1$), type $f$ (${\times}{\square}{\times}{\triangle}$, mixed three-coloured), type $g$ (${\times}{\square}{\triangle}{\diamondsuit}$, four-coloured or polychromatic).Let $S$ be a subset of $\{a,b,c,d,e,f,g\}$. An $m$-colouring $\phi$ of $(V,{\cal B})$ is said of type $S$ if the type of every $4$-cycle of $\cal B$ is in $S$. A type $S$ colouring is said to be proper if for every type $\alpha \in S$ there is at least one $4$-cycle of $\cal B$ having colour type $\alpha$.We say that a $P(v,3,1)$, $(W,{\cal P})$, is embedded in a $4$-cycle system of order $n$, $(V,{\cal B})$, if every path $p=[a_1,a_2,a_3] \in {\cal P}$ occurs in a $4$-cycle $(a_1,a_2,a_3,x) \in {\cal B}$ such that $x \notin W$.In this paper we consider the following spectrum problem: given an integer $m$ and a set $S \subseteq \{b,d,f\}$, determine the set of integers $n$ such that there exists a $4$-cycle system of order $n$ with a proper $m$-colouring of type $S$ (note that each colour class of a such coloration is the point set of a $P_3$-design embedded in the $4$-cycle system).We give a complete answer to the above problem except when $S=\{b\}$. In this case the problem is completely solved only for $m=2$.

AbstractTemperature is one of the important environmental factors affecting plant growth, yield and quality. Moreover, appropriately low temperature is also beneficial for tuber coloration. The red potato variety Jianchuanhong, whose tuber color is susceptible to temperature, and the purple potato variety Huaxinyangyu, whose tuber color is stable, were used as experimental materials and subjected to 20 °C (control check), 15 °C and 10 °C treatments during the whole growth period. The effects of temperature treatment on the phenotype, the expression levels of structural genes related to anthocyanins and the correlations of each indicator were analyzed. The results showed that treatment at 10 °C significantly inhibited the potato plant height, and the chlorophyll content and photosynthetic parameters in the leaves were reduced, and the enzyme activities of SOD and POD were significantly increased, all indicating that the leaves were damaged. Treatment at 10 °C also affected the tuberization of Huaxinyangyu and reduced the tuberization and coloring of Jianchuanhong, while treatment at 15 °C significantly increased the stem diameter, root-to-shoot ratio, yield and content of secondary metabolites, especially anthocyanins. Similarly, the expression of structural genes were enhanced in two pigmented potatoes under low-temperature treatment conditions. In short, proper low temperature can not only increase yield but also enhance secondary metabolites production. Previous studies have not focused on the effects of appropriate low-temperature treatment during the whole growth period of potato on the changes in metabolites during tuber growth and development, these results can provide a theoretical basis and technical guidance for the selection of pigmented potatoes with better nutritional quality planting environment and the formulation of cultivation measures.

Frontiers in Plant Science 11 (7 de enero de 2021). http://dx.doi.org/10.3389/fpls.2020.600704.
Texto completoResumen
Anthocyanins spatiotemporally accumulate in certain tissues of particular species in the banana plant, and MYB transcription factors (TFs) serve as their primary regulators. However, the precise regulatory mechanism in banana remains to be determined. Here, we report the identification and characterization of MaMYB4, an R2R3-MYB repressor TF, characterized by the presence of EAR (ethylene-responsive element binding factor–associated amphiphilic repression) and TLLLFR motifs. MaMYB4 expression was induced by the accumulation of anthocyanins. Transgenic banana plants overexpressing MaMYB4 displayed a significant reduction in anthocyanin compared to wild type. Consistent with the above results, metabolome results showed that there was a decrease in all three identified cyanidins and one delphinidin, the main anthocyanins that determine the color of banana leaves, whereas both transcriptome and reverse transcription–quantitative polymerase chain reaction analysis showed that many key anthocyanin synthesis structural genes and TF regulators were downregulated in MaMYB4 overexpressors. Furthermore, dual-luciferase assays showed that MaMYB4 was able to bind to the CHS, ANS, DFR, and bHLH promoters, leading to inhibition of their expression. Yeast two-hybrid analysis verified that MaMYB4 did not interact with bHLH, which ruled out the possibility that MaMYB4 could be incorporated into the MYB-bHLH-WD40 complex. Our results indicated that MaMYB4 acts as a repressor of anthocyanin biosynthesis in banana, likely due to a two-level repression mechanism that consists of reduced expression of anthocyanin synthesis structural genes and the parallel downregulation of bHLH to interfere with the proper assembly of the MYB-bHLH-WD40 activation complex. To the best of our knowledge, this is the first MYB TF that regulates anthocyanin synthesis that was identified by genetic methods in bananas, which will be helpful for manipulating anthocyanin coloration in banana programs in the future.

Texto completoResumen
Serological methods serve as a direct or indirect means of pathogen infection diagnosis in plant and animal species, including humans. Dot-ELISA (DE) is an inexpensive and sensitive, solid-state version of the microplate enzyme-linked immunosorbent assay, with a broad range of applications in epidemiology. Yet, its applicability is limited by uncertainties in the qualitative output of the assay due to overlapping dot colorations of positive and negative samples, stemming mainly from the inherent color discrimination thresholds of the human eye. Here, we report a novel approach for unambiguous DE output evaluation by applying machine learning-based pattern recognition of image pixels of the blot using an impartial predictive model rather than human judgment. Supervised machine learning was used to train a classifier algorithm through a built multivariate logistic regression model based on the RGB (“Red,” “Green,” “Blue”) pixel attributes of a scanned DE output of samples of known infection status to a model pathogen (Lettuce big-vein associated virus). Based on the trained and cross-validated algorithm, pixel probabilities of unknown samples could be predicted in scanned DE output images, which would then be reconstituted by pixels having probabilities above a cutoff. The cutoff may be selected at will to yield desirable false positive and false negative rates depending on the question at hand, thus allowing for proper dot classification of positive and negative samples and, hence, accurate diagnosis. Potential improvements and diagnostic applications of the proposed versatile method that translates unique pathogen antigens to the universal basic color language are discussed.

Texto completoResumen
It has been shown the role of carbon of dissolved organic matter (C DOM) in humus composition of irrigated chernozems as well as participation of humus substances proper in the formation of DOM. It has been found out that in chernozem long-term irrigated with weakly alkaline water the yield of C DOM is reliably higher than in nonirrigated soil when used even ordinary water extraction. It accounts for 53 and 40 mg l–1 respectively. It is attributed to the fact that because of influence of irrigative water the pH range became wider to some extent and alkalinity of soil medium became stronger and consequently the solubility of DOM increased. It has been noted that that the same tendency that is decrease is observed in depthwise distribution of humus and C DOM. As it should be expected, in irrigated soil processed with irrigative water the content of C DOM is somewhat higher (by 7–10 mg l–1) in the studied part of the profile as a whole. At the same time the relative role of C DOM in humus composition increases with increasing pH, up to 3 % of total organic soil carbon. It has been examined the interaction of irrigative water free of DOM with preparations of humus acids extracted from soil. Drown coloration of irrigative water is evidence of separation of DOM from humus acids. Moreover, the yield of C DOM proved to be three times higher in case of irrigative water than distilled one and accounted 120 and 350 mg l–1 respectively. This comparative experiment is an evidence of the fact that humus acids
can be served as a source of DOM, especially in the event if more accessible organic matter is not available. Thus, long-term irrigation of chernozems in case of unsatisfactory application of organic fertilizers leads not only to biological and irrigational humus losses but also humus losses by way of transformation of humus acids into DOM

Texto completoResumen
Deficit irrigation (DI) is an irrigation scheduling technique that is used in grapes to improve red color development; however, results are not always satisfactory in table grapes. The red color in grapes is mainly due to the plant pigment anthocyanin. In the present study, the anthocyanin biosynthesis in Scarlet Royal grapes (Vitis vinifera L.) grown in the San Joaquin and Coachella Valleys, and subjected to two different DI strategies was investigated. The objective of this study was to identify potential regulatory factors that may lead to potential treatments to improve red color in table grapes, especially under warm climate conditions. In both locations, DI induced the expression of several genes involved in three major pathways that control the red color in table grapes: anthocyanin biosynthesis, hormone biosynthesis, and antioxidant system. DI at veraison induced anthocyanin accumulation and enhanced red color in berries at harvest time. However, anthocyanin accumulation was lower at the Coachella Valley compared to the San Joaquin Valley. The lower level of anthocyanin was associated with lower expression of critical genes involved in anthocyanin biosynthesis, such as flavonoid-3-O-glucosyltransferase (UFGT), myb-related regulatory gene (R2R3-MYB) (MYBA1), basic helix-loop-helix (bHLH) (MYCA1) and the tryptophan-aspartic acid repeat (WDR or WD40) proteins (WDR1). Further, gene expression analysis revealed the association of ABA biosynthesis gene 9-cis-epoxycarotenoid dioxygenase (NCED1), 1-aminocyclopropane-1-carboxylic acid oxidase (ACO3), and the gibberellic acid (GA) catabolic gene GA2 oxidase (GA2ox1) in the induction of anthocyanin biosynthesis. An increase in the chalcone synthase gene (CHS2) was observed in response to DI treatments in both sites. However, CHS2 expression was higher in Coachella Valley after ending the DI treatment, suggesting the involvement of environmental stress in elevating its transcripts. This data was also supported by the lower level of antioxidant gene expression and enzyme activities in the Coachella Valley compared to the San Joaquin Valley. The present data suggested that the lack of grape red coloration could partially be due to the lower level of antioxidant activities resulting in accelerated anthocyanin degradation and impaired anthocyanin biosynthesis. It seems that under challenging warmer conditions, several factors are required to optimize anthocyanin accumulation via DI, including an active antioxidant system, proper light perception, and hormonal balance.

The need to intensify the extraction process using the influence of chemical reagents on beet chips was substantiated. The analysis of appli-cation of natural sorbents in food production technologies was carried out. The physical and chemical properties of zeolite were explored. The indicators that make it possible to apply natural zeolite for additional treatment of water and juices in sugar production were shown. The effectiveness of the use of natural zeolite for feed water treat-ment with the view to enhancing the technological quality of diffusive juice was determined. Experimental research revealed that feed water treatment with zeolite decreases the content of total iron, ammonium, and permanganate oxidation indicator. It was proved that microbial seeding of feed water and diffusive juice decreases in case of treatment with zeolite. It was established experimentally that the purification of diffu-sion juice occurs during zeolite application for feed water treatment. We determined the effectiveness of removal of macromolecular compounds, including dextran, from diffusive juice obtained during processing sugar beets of various technological quality with natural zeolite. It was shown that at the zeolite consumption of 0.1...0.4 % to the weight of beets, the content of high-molecular compounds and pectic substances in diffusive juice decreases by 30–40 %, and the content of dextran – by 20–40 %, respectively. During the zeolite treatment, an enhancement of the quality of purified juice and improvement of filtration and saturation proper-ties of defeco-saturated precipitate are observed. Thus, the average rate of sedimentation of the precipitate of juice of І carbonation S5 m, when using zeolite for feed water preparation increases by 10–50 % for the beet different technological quality. In the course of research, we designed the technique of zeolite application, which ensures a decrease in coloration, an increase in the purity of the cleared juice, enhancement of filtration and sedimentation properties of the precipitate of juice of I carbon-ation. High effectiveness of the proposed method is pronounced in processing raw materials of lowered quality. Thus, there are some grounds to claim the effectiveness of zeolite application to enhance the quality of diffusion juice and products in sugar production. Keywords: diffusion juice, dextran, sucrose extraction, purification of diffusion juice, zeolite.

Num 16 is a composite rebellion narrative that consists of three different strands: a non-P story of Dathan and Abiram and two stories with priestly flavor – one concerning the 250 chieftains of Israel and one involving Korah with the Levites. A redaction-critical analysis suggests that the first two stories had existed separately and were combined by a redactor responsible for the addition of the passage about Korah and the Levites. The layers of the 250 chieftains and Korah represent, respectively, two phases of the Zadokites‹ struggle for their priestly prerogatives in the Jerusalem temple against the elders of the community and the powerful Levites in the Persian period. Along with those layers, Zadokite compositional and redactional passages are found throughout Exodus-Leviticus-Numbers and focus mainly on the Zadokites‹ own socio-religious interests. These passages are located in post-Priestly strata, constituting the latest layers in the Pentateuch.Num 16 besteht als zusammengesetzte Erzählung zum Aufstand der Söhne Korachs aus drei Strängen: eine nichtpriesterliche Geschichte von Dathan und Abiram und zwei Erzählungen mit priesterlichem Flair zu 250 Anführern Israels und zu Korach und den Leviten. Eine redaktionskritische Analyse zeigt, dass die ersten beiden Erzählungen getrennt voneinander existierten und durch den Redaktor zusammengefügt wurden, der dabei die Abschnitte zu Korach ergänzte. Die Stränge zu den 250 Anführern und zu Korach repräsentieren zwei Phasen des Kampfes der Zadokiden um die priesterliche Vorherrschaft in Jerusalem. Spuren dieser Auseinandersetzung finden sich auch in Ex-Num und gehören zu den späten nachpriesterlichen Schichten des Pentateuchs.Nb 16 est un récit de rébellion composite, qui comporte trois volets : l’histoire non-P de Datân et Abiram et deux histoires à coloration sacerdotale – celle des 250 chefs d’Israël et celle de Coré et des lévites. La critique rédactionnelle de ce chapitre suggère que les deux premières histoires ont existé séparément et ont été combinées par un rédacteur responsable de l’addition du passage sur Coré et les lévites. La couche du récit des 250 chefs et celle de l’épisode de Coré représentent respectivement deux phases du combat des Sadocides pour leurs prérogatives sacerdotales dans le Temple de Jérusalem pendant la période perse contre les anciens de la communauté et les puissants Lévites. En lien avec ces couches, on trouve dans l’ensemble Exode-Lévitique-Nombres des passages qui sont des compositions et des rédactions sadocides principalement centrées sur les intérêts socio-religieux propres à ce groupe. Ces passages se trouvent dans des strates post-sacerdotales, qui comptent parmi les couches les plus récentes du Pentateuque.

Abstract Poster session 3, September 23, 2022, 12:30 PM - 1:30 PM Objectives: Methodology: A hospital-based cross-sectional study was conducted for 6 months in the Department of Microbiology of Sukraraj Tropical and Infectious Disease Hospital, Kathmandu, Teku, Nepal. A total of 408 HIV-positive patients attending the ART center of the hospital of different age and sex were included in the study. Study variables like CD4 + count, tobacco consumption, diabetes, URTI, and recent antibiotic consumption were noted. Standard microbiological guidelines were followed for the oral swab collection and transportation. Specimen was seeded on SDA agar plates (SDA with chloramphenicol and cycloheximide). Preliminary identification of the Candida was done on the basis of colony characteristics, gram staining, and germ tube test. Further for the speciation of Candida species, HiCrome™ Candida Differential Agar (HImedia, India) was applied where on the basis of coloration and colony morphology speciation was done. Similarly, Cornmeal Agar (Dalmau plate culture technique) and sugar Fermentation test were applied to confirm the Candida species. Muller-Hinton agar supplemented with 2% glucose and 0.5 μg/ml methylene blue dye (GMB) medium was used to perform the antifungal susceptibility testing of Candida isolates. Antifungal susceptibility testing (AST) of isolates was performed and interpreted according to Clinical and Laboratory Standards Institute (CLSI) M44-A document. Candida albicans ATCC 90028 was taken as the reference strain. All the data were entered in Microsoft excel and Chi-square was used to find out the association between the frequency of oral candidiasis and study variables. Results Among 408 studied subjects, 225 (55.1%) were males and 183 (44.9%) were females. Of the participants, 116 (28.4%) had regular tobacco smoking habit, diabetes 10 (2.5%), URTIs 30 (7.4%), antibiotic consumption 44 (10.8%) and ART use 394 (96.6%). The CD4 + cell count of respondents ranged from 12 - 2425 cells/mm³. Candida albicans 53 (81.5%) was the most frequently encountered species followed by C. tropicalis 3 (4.6%), C. krusei 2 (3.1%), C. glabrata 1 (1.5%) and 6 (9.2%) other Candida species. A total of 26 patients had CD4+ ≤200 cells/mm3 and 39 patients had CD4+ >200 cells/mm3. There was no significant association in the occurrence of oral candidiasis among males and females (P = .966), tobacco consumption (P = .051), ART use (P = .188), diabetes (P = .722). Whereas, there was a significant association between oral Candida carriage and CD4 + cell count ≤ 200 cells/mm3 (P <.001), URTI (P = .029), and recent antibiotic consumption (P = .002). Amphotericin B was the most potent antifungal followed by voriconazole, itraconazole, and conversely fluconazole the most resistant. Conclusion Candida albicans was the common species isolated in our study. Candida Chrome Agar can be used as a routine media for rapid identification and Candida speciation. AST needs to be done routinely to know the susceptibility pattern of isolates and initiate proper treatment of patients. Since oral yeast colonization was associated with low CD4 + count (<200 cells/mm3). Thus, oral lesions can serve as early markers for HIV infection.
