Effect of hyperthermia on hematological parameters and productivity of laying hens

Studies were conducted in the period 2020-2021 based on the department of ecology and noncontagious pathology of animals of the Ural Veterinary Research Institute - a structural subdivision of FSBSI “UFARC UB RAS” (Federal State Budgetary Scientific Institution “Ural Federal Agrarian Research Center of the Ural Branch of the Russian Academy of Sciences”). Significant increases in ambient temperature in industrial poultry farming have natural and incidental effects on all processes in the living organism of birds, affecting their direction and intensity. We studied the use of feed additives containing dried live yeast of different variants and concentrations before and after heat stress on changes in the live body weight of laying hens, the importance of laid eggs, and quantitative and qualitative characteristics of the blood leukocyte formula. The authors registered a significant increase in the concentration of erythrocytes and hemoglobin in birds of the control group - 18.1 and 25.5% during the period of heat stress, which indicated the beginning of a long adaptation process.Furthermore, the authors noted a significant increase in the ratio of the number of heterophils to lymphocytes (g/l) and in individuals of the control group by 44.2% (0.62 units), which confirmed the intensity of all processes in the body. During the study, the authors note that the total number of leukocytes increased against the background of a stress factor in the blood of laying hens of the control, 1st, and 2nd experimental groups - 1.4, 1.2, and 1.3 times, respectively. This increase occurs due to the release of immature heterophils into the bloodstream and the outflow of lymphocytes into peripheral tissues. The authors note the best stress resistance to 48-hour hyperthermia when using feed additives of hepatoprotective action in chickens of the 1st and 2nd groups reported the best stress resistance to 48-hour hyperthermia. This stress resistance is confirmed by regular physiological changes in the level of heterophils, basophils, monocytes, and G/L, characteristic of the period of urgent adaptation and maintenance of immune homeostasis.

I’ve just found 10,000 ways that will not work.” –Thomas EdisonScientists and engineers often come up with brilliant ideas, but in the end technology is only as good as its adoption and proper use. This is true for regardless of how complicated or simple the technology.Household water treatment, also commonly referred to as point-of-use (POU) water treatment, is a strategy to improve access to safe water that was introduced within the water, sanitation, and hygiene (WASH) field1 because many communities in lower- and middle-income country (LMIC) settings lack access to a full-scale water treatment plant. With POU treatment, residents can conduct at least some elements of treatment (coagulation and sedimentation, filtration, ultraviolet disinfection, or chemical inactivation) in their own homes, offering them the capacity to disinfect their own water. Treating water in the home also has the benefit of minimizing recontamination after collection, a well-documented phenomenon in locations where people fetch their water from locations outside the home.2,3Chlorination has been seen as a particularly promising POU approach because it leaves a residual disinfectant in the water to address microbial intrusion during storage.4 In LMICs, many studies have been carried out on the effectiveness of household drinking water chlorination for preventing diarrhea. A recent systematic review found that, compared with untreated drinking water from an unimproved source, risk of diarrhea was reduced by 44% with POU chlorination of water [lowercase italic n equals 25n=25 studies; 0.66 (0.56–0.77)].5However, although understanding the potential health impact of a technology is important, understanding whether and why people use, or do not use, a proposed technology is equally important. In their review in this issue of Environmental Health Perspectives, Crider et al. do just this, addressing barriers to the adoption of POU chlorination for household drinking water treatment by 46 target populations.6Considering users’ needs and interests is essential to adoption of a technology. For example, the authors found that bad taste, smell, or appearance of treated water was cited by a large percentage of households, as was lack of time to spend on disinfection (a time burden usually placed on women). Most of the intervention groups received chlorination products for free; households in the groups that did not cited price or availability of products as a barrier to repurchase and continued use.In addition to the identification of specific barriers to adoption two other aspects stood out in the review. First, the authors identified a sheer lack of information on barriers to adoption. “Much of the time, the reasons for low adoption are poorly understood simply because the relevant data are not systematically collected,” they stated. The authors excluded 27 of 63 otherwise-eligible studies because quantitative measures of adoption were not reported. Among those that did report a measure of adoption, there was no consensus definition of adoption, and several studies emphasized reasons for use rather than nonuse.Second, lack of attention in the field to user adoption as a signal of intervention success is also belied by the language that researchers use to describe it. Different words used in the literature to describe what Crider et al. appropriately refer to as “adoption” of water chlorination practices range from “adherence” or “compliance” to “use/usage” or “uptake.”6 Public health inherited the language of “compliance” and “adherence” from medicine, where it describes how often patients follow through with a medication regimen.7,8 Although subtle, this language is important because the medical words put the burden of failed adoption on the user, whereas “adoption,” “use/usage,” and “uptake” put this burden on the implementer.Time and again we see environmental health–based interventions fail because we are not focused enough on the actual uptake of a technology. This is also true for other areas of environmental health, such as household air pollution (HAP).9,10 The WASH and HAP fields are increasingly recognizing the importance of applying approaches from systems science and implementation science to increase the chances of success for environmental health interventions.10,11This work is critical. Our practices, and our language, must center on users’ needs and interests if we hope for adoption of new technologies to improve population health related to environmental conditions.

Supporting the Next Generation of Leaders in the Geosciences: Barnard’s Environmental Science Pathways Scholar Program

To address the national need to diversify the geosciences, we created the cohort-based Environmental Science Pathways Scholars Program, or E(SP)2, for undergraduates in the Environmental Science Department at Barnard College who identify as Black, Indigenous, and people of color (BIPOC), first generation, or low income. By fostering a more inclusive community in the particularly formative stages of academic and early professional development, E(SP)2 aims to support and retain a diverse cohort of students who have developed confidence in their scientific skills and identities, and who share a passion for environmental science. E(SP)2 is modeled on the Science Pathways Scholar Program [(SP)2] at Barnard College, an active and successful multidisciplinary opportunity at Barnard College.

Tożsamość w krajobrazach nie tylko kulturowych województwa mazowieckiego

The article presents areas distinguished by local tradition and the preservation of rituals and customs in the Mazovian Voivodeship (Mazovia region) and points out the role of society in shaping and preserving intangible cultural heritage. Additionally, an assessment of the state of preservation or development of synthetic characteristics of the municipal landscape, such as tradition, identity, and localness, was carried out following the methodology outlined in the Ordinance of the Council of Ministers dated January 11, 2019, regarding the preparation of landscape audits. The analyses were conducted based on the results of a survey carried out by the research team of the Department of Spatial Planning and Environmental Sciences at the Faculty of Geodesy and Cartography at the Warsaw University of Technology, commissioned by the Mazovian Office of Regional Planning in Warsaw, within the territory of the Mazovian Voivodeship. The research survey included 9 questions related to cultural heritage, of which, for the purposes of this article, 4 questions directly related to material and intangible heritage were analyzed among the 6,160 surveys conducted. The scope of analysis of material heritage pertained to the presence of traditional architecture, and the intangible heritage included ethnographic regions, preserved traditions, rituals, and customs, as well as the engagement of the society in the “cultural life” of their small homelands. The analysis of the questionnaires allowed for the confirmation of the presence of previously identified and indicated elements in the documents of the voivodeship self-government, as well as the identification of new areas of tangible and intangible cultural heritage in the Mazovian voivodeship. These findings were compared with the literature on the subject and the records in the documents of the voivodeship self-government. The results of the study indicated the significant role of local self-government units, cultural institutions, as well as associations and organizations that bring together local communities in shaping and preserving the intangible cultural heritage. The degree of engagement of the respondents in cultivating traditions, rituals, and customs was found to be independent of their location in ethnographic regions, according to the survey responses. The responses of the survey participants also pointed to the “return to roots” trend resulting from the growing interest in folk culture, supported by popularizing and promoting folk traditions. In the process of intergenerational transfer of values and the richness of cultural heritage, education of the society, especially the younger generation, plays a crucial role. Key words: cultural landscape, tradition, architecture, ethnographic regions, cultural heritage

Indicator plants of anthropogenic disturbances: Scientific approach, educational technologies

The technology of using the indicative properties of plants both for obtaining scientific results and teaching this technique to students and young scientists is proposed for implementation. Aspects of research organization and didactic work in the implementation of the environmental monitoring program of Donbass are highlighted. Over the period of research (1996-2023), high levels of pollution and anthropogenic transformation of ecosystems in the industrial areas of Eastern Europe have been established. The data are based both on experiments in open landscapes and laboratory conditions, special procedures for statistical processing and interpretation of the results. These localities of intensive economic use are the places of great scientific and applied interest to ecologists and educators in this area. Indicator plants are visual objects in the knowledge of the fundamental nature and practical use for information about the quality of the environment. In scientific and educational activities the following are important: organization of a laboratory, availability of equipment, functioning of a museum, a card-index, a herbarium fund, the possibility of introducing case studies technology, the theory of solving inventive tasks, conducting interactive lectures, seminars, demonstration experiments and special modern technologies for training environmental specialists – modeling and land-use forecasting and urbanized environment. Methods of implementation of scientific and pedagogical experiment on phytomonitoring and ecological expertise with the help of plants have been introduced into work with students, postgraduates and young scientists of the Department of Botany and Ecology of Donetsk State University.

Studies on parasitic prevalence in pet birds from Punjab, Pakistan.

During this one year study, blood and fecal samples of doves (Zenaida asiatica), ducks (Anas platyrhynchos), pigeons (Columba livia), partridges (Alectoris chukar), turkeys (Meleagris gallopavo) and goose (Chen caerulescens) were collected to assess the parasitic prevalence in these birds. The birds were kept at Avian Conservation and Research Center, Department of Wildlife and Ecology, University of Veterinary and Animal Sciences, Lahore. All these avian species were kept in separate cages and their entire body was inspected on regularly basis to record external parasites. For internal parasites, 100 blood and 100 fecal samples for each species were analyzed. During present study, two species of ectoparasites i.e. fowl ticks (Args persicus) and mite (Dermanyssus gallinae) while 17 species of endoparasites; three from blood and 14 from fecal samples were identified. Prevalence of blood parasites was Plasmodium juxtanucleare 29.3%, Aegyptinella pullorum 15% and Leucoctoyzoon simond 13%. Parasitic species recorded from fecal samples included 6 species of nematodes viz. Syngamus trachea with parasitic prevalence of 50%, Capillaria anatis 40%, Capillaria annulata 37.5%, Heterakis gallinarum 28.3%, Ascardia galli 24% and Allodpa suctoria 2%. Similarly, two species of trematodes viz. Prosthogonimus ovatus having parasitic prevalence of 12.1% and Prosthogonimus macrorchis 9.1% were also recorded from fecal samples of the birds. Single cestode species Raillietina echinobothrida having parasitic prevalence of 27% and 3 protozoan species i.e. Eimeria maxima having prevalence 20.1%, Histomonas meleagridis 8% and Giardia lamblia 5.3% were recorded. In our recommendation, proper medication and sanitation of the bird's houses and cages is recommended to avoid parasites.

FOLIAR APPLICATION OF POTASSIUM AND GIBBERELLIC ACID (GA3) TO ALLEVIATE DROUGHT STRESS IN WHEAT

To investigate the ameliorative effect of foliar application of potassium and gibberellic acid on wheat to drought stress an experiment was conducted at the research field and laboratory of Crop Physiology and Ecology Department, Hajee Mohammad Danesh Science and Technology University (HSTU), Dinajpur during the period of November 2018 to March 2019. The experiment was laid out in a split plot design with three replications. Four growing conditions viz. well water (WW), water deficit stress (WDS), foliar application of 2.23% K2SO4 under WDS and foliar application of 300 ppm GA3 under WDS were set up as the main plot treatment and two wheat varieties (Kanchan and BARI Gom-30) were set up as sub plot treatment. Non-irrigated water stress significantly reduced different physiological traits, yield and yield attributes except proline content of flag leaf of wheat, whereas foliar application of potassium and GA3 improved these traits under WDS. Foliar application of potassium improved biological yield (22.04% and 15.16%) and grain yield (3.19% and 2.59%) in Kanchan and BARI Gom-30, respectively, whereas foliar application of GA3 improved biological yield (12.12% and 17.00%) and grain yield (1.47% and 1.18%) in Kanchan and BARI Gom-30, respectively under WDS. Though, foliar application of potassium and GA3 ameliorated the adverse effect of drought on wheat but potassium was found more effective. Therefore, it may be concluded that additional foliar application of potassium along with recommended potassium could improve production of wheat under drought

Growth Performance of Black Pepper (P. nigrum) Cuttings in Different Rooting Media and Growth Regulators

Black pepper (Piper nigrum) is recognized as "Black Gold" and "King of Spices" because of its widespread use in culinary preparation, food flavoring, and condiment seasoning. It has worldwide fragrance and medical use. The purpose of the conducted research was to investigate growth performance of P. nigrum cuttings in various rooting media and growth regulators concentrations in a low-cost non-mist propagation chamber at the Agroforestry Field Laboratory, Department of Agroforestry and Environmental Science, Sylhet Agricultural University, Sylhet during the period starting from August 2019 to June' 2020. The experiment consisted of two factors: different rooting media and different concentrations of growth regulator, IBA (Indole 3-Butyric Acid). Under the first factor, there were four treatments, namely M1= biochar, M2= vermicompost, M3= well-decomposed cow dung, and M4= field soil as control. Under the second factor, there were four treatments, namely R1= 0.2%, R2= 0.4% and R3= 0.8%, and R4= 0.0% of IBA. The whole experiment was designed in a factorial RCBD (Randomized Complete Block Design) with three replications. Among the different media, M1 treatment (biochar) exhibited superior performance concerning vine length and the number of nodes per vine. On the other hand, R2 treatment (0.4%) concentration of IBA showed better performance regarding the number of roots and vine length. The research found that the growth performance of P. nigrum cuttings are accelerated through integrating rooting media and growth regulators. Consequently, the demand for planting materials could be met.

A research agenda for nonvascular photoautotrophs under climate change.

Nonvascular photoautotrophs (NVP), including bryophytes, lichens, terrestrial algae, and cyanobacteria, are increasingly recognized as being essential to ecosystem functioning in many regions of the world. Current research suggests that climate change may pose a substantial threat to NVP, but the extent to which this will affect the associated ecosystem functions and services is highly uncertain. Here, we propose a research agenda to address this urgent question, focusing on physiological and ecological processes that link NVP to ecosystem functions while also taking into account the substantial taxonomic diversity across multiple ecosystem types. Accordingly, we developed a new categorization scheme, based on microclimatic gradients, which simplifies the high physiological and morphological diversity of NVP and world-wide distribution with respect to several broad habitat types. We found that habitat-specific ecosystem functions of NVP will likely be substantially affected by climate change, and more quantitative process understanding is required on (1) potential for acclimation, (2) response to elevated CO2 , (3) role of the microbiome, and (4) feedback to (micro)climate. We suggest an integrative approach of innovative, multimethod laboratory and field experiments and ecophysiological modelling, for which sustained scientific collaboration on NVP research will be essential.

Assessment of environmental pollution by lead and its impact on the child's body (using the example of the Callao region in Peru)

In the presented work, based on the existing information in abstract sources, as well as freely available statistical material collected by the Department of Ecology, Environmental Protection and Occupational Health Monitoring of the Callao region in Peru, the actual problem of lead pollution on a global scale is outlined, and ways to solve it are shown on the example of Peru, a country that is one of the leaders extraction of this metal. The analysis of the degree of pollution and the impact of lead on the environment, the assessment of the levels of lead in the blood of children living in the Callao district and the associated negative impact of lead pollution on the child's body was carried out. The article shows that in children, the earliest manifestations of lead exposure occur even at a blood level of only 10.0 micrograms/dl, while in Callao, lead levels in children's bodies are higher than this value. Levels from 50 to 60 mg/dl of lead are recorded here, while the maximum value in children under the age of 12 according to the World Health Organization (WHO) should not exceed 10 mg/dl. It is shown that a high proportion of children with elevated levels of lead in the blood is associated with the presence of industrial centers specializing in the melting of metals and the disposal of lead. The direction of winds, mainly from south to north and from southwest to northeast, could explain the higher proportion of children with elevated lead levels among residents of areas located in the north and northeast. As a result of data analysis, it was revealed that the control value less than 10 micrograms/dl, used as a threshold, is insufficient to preserve the health of the population. In addition, the article discusses possible ways to reduce pollution: through the implementation of programs for monitoring and assessing the environmental quality of the environment by companies engaged in the extraction of lead minerals. It is also necessary to comply with national environmental quality standards for lead content. Guidelines for various types of economic activities leading to the reduction of environmental pollution are proposed.

Response Of A Medicinal Plant Peganum Harmala To Iron Oxide Nanoparticles F3O4(Nps)

Iron nanomaterials are widely present in the environment and their concentrations are increasing day by day. In many applications, iron nanomaterials are included, but the minimum and maximum concentrations that are not harmful to plants are not yet known. Effect of F3O4(NPs) on Peganum harmala plants for the purpose of showing anatomical responses as effective biomarkers for increasing the concentration of nanomaterials in the ecosystem. Electron microscopy to determine the effect of different doses of F3O4(NPs) ranging from (0-600 mg / L) were used. The cross-sections of leaves were compared in terms of epidermis, parenchyma cells, vascular cylinder, especially xylem and phloem vessels. Epidermal variations were studied stomata, guard cells and normal cells of the epidermis. The laboratories of the Department of Environmental Sciences and Pollution at the College of Science, University of Kufa for the year 2022 were used to conduct experiments. The anatomical results of the studied plants showed that the largest effect was on the epidermis of the plants, especially on the stomata system, where the stomata were closed and decreased in number, while the vascular system was less affected by the variation in the concentration of F3O4(NPs) compared to the rest anatomical indicators. The severity effect was proportional to the increase in concentration. The results indicate that an insufficient supply of F3O4(NPs) (150 mg / L) can be a plant growth stimulator and the results can be used in practical applications to increase production and improve crops as a fertilizer. Whereas, treatments with high concentrations inhibit antioxidants, causing a deficiency of growth activity in plants.

​Influence of Paper Mill Effluent Irrigated Soil Characteristics under Laboratory and Field Conditions

Background: The solid wastes and the wastewater (effluent) generated in the pulp and paper industry can be used to improve the soil fertility. However, the cation concentration in these residues can influence the bioavailability of some nutrients and soil properties. The objective of this study is to experiment the availability of the cations namely Ca, Mg, Na and K in laboratory (column) and the field. Methods: An experiment with PVC column was carried out in the laboratory to study the availability of cations as influenced by 13 irrigations with papermill effluent vis-à-vis in a field experiment in the Department of Environmental Sciences, Tamil Nadu Agricultural University, Coimbatore during 2019-2020. Result: The pH, EC and the concentration of the cations were higher in the field soil compared to the column soil barring magnesium. This may be due to the clogging of pores resulting in decreased infiltration in field soil.

Hygienic assessment of manganese content in household and drinking water supply sources of the Vladimir region

Introduction. One of the most important tasks to ensure the sanitary and epidemiological well-being of the population of the Vladimir region is to provide it with high-quality drinking water. Due to the territory of the region to be partially associated with known hydrogeochemical anomalies of excess manganese content in groundwater, a hygienic assessment of the water of economic and drinking sources was carried out according to the content of this element. Materials and methods. The paper presents the data of own research of the Department of Biology and Ecology of the Vladimir State University named after A.G. and N.G. Stoletov for 2021. During this period, the authors of the work examined about 110 samples of water from the household and drinking centralized and non-centralized water supply of the Vladimir region. Water samples were taken in the largest settlements (these are district centers, regional cities and large district settlements) and from drinking water sources of individual farms located in the territory of the region in various districts. The manganese content in water was determined on the analyzer “Fluorat-02-5M” according to HDPE F 14.1:2:4.188-02. Results. The drinking water of the centralized water supply of the Vladimir region in terms of manganese content was established to meet regulatory requirements and be safe for the health of the resident population. In all samples of drinking water, the concentration of manganese is below 0.1 mg/dm3. At the same time, water from underground sources of non-centralized water supply has in some cases an excess of manganese (from 2 to 7 MPC), which is primarily due to the specifics of the geochemical composition of the water-bearing rocks of these territories. Conclusion in order to provide the population of territories using underground water with a high content of manganese, it is necessary to build local modular water treatment plants using modern methods of non-reactive de-ironing and demanganation and using effective modern equipment and filtering materials.

Pheno-thermal response of Chrysanthemum under different environments in mid hills of Himachal Himalayas

This paper briefly reports some effects of date of transplanting, row spacing and their orientation on the pheno-thermal response of Chrysanthemum. In order to study the effect of heat, photothermal and heliothermal units on the phenology of Chrysanthemum, an experiment was conducted during 2019-2020 on Solan Shringar cultivar of Chrysanthemum at experimental farm of Department of Environmental Science, Dr. Y S Parmar University of Horticulture & Forestry Nauni (30o86'N, 77o16'E and 1275 m amsl). The weather based indices were used for characterizing the thermal response to various phenophases of Chrysanthemum under different environmental conditions. The maturity was differed by 13 days for early, mid and late transplanting dates for which the accumulated range of growing degree days was 2278-2291, 2062-2067 and 1826-1827o C days; photothermal unit was 11240-11366, 9266-9336o C days under different treatments. Likewise, minimum heliothermal unit was required by the treatment D3S1O2 (23602o C days) and maximum under the treatment D1S1O2 (29958o C days). Highest and lowest heat use efficiency was recorded under D1S1O1 (5.4) and D3S2O2 (2.8) treatment, respectively. The weather indices explained 73-98% variation in vegetative and 88-92 % reproductive phenophase of Chrysanthemum under different treatments.

Evaluating Morphological Methods for Sex Estimation on Isolated Human Skeletal Materials: Comparisons of Accuracies between German and South African Skeletal Collections

Objectives: The focus of this research is to evaluate the sex estimation methods on isolated human materials by applying morphological methods published in various forensic and anthropological literature on different skeletal series. Materials and Methods: 165 individuals from the 19th to 20th century Inden skeletal series, 252 individuals from the 13th to 14th century Lübeck skeletal series of German ancestry housed at the Department of Historical Anthropology and Human Ecology, the University of Göttingen, Germany, and 161 individuals from the 19th and 20th century of South African African ancestry housed within the Raymond A. Dart collection of modern human skeletons at the University of Witwatersrand, South Africa, with crania, mandibles, and pelves, were assessed. The evaluation criteria are burial information on the Inden series, genetic sex on both the Inden and the Lübeck series, and previous demography on cadavers from the South African African series. Results and Discussion: The sex estimation with cranial traits perform better in Inden and South Africa samples and worse in Lübeck sample. The mandible accuracies for pooled sexes are not exemplary, but the individual traits perform better for males in the Inden, Lübeck, and South Africa samples, except for gonion and angle, which performs better in females. The pelvic traits perform better in the Inden and South Africa samples compared to the Lübeck sample. The statistical tests show that there is a huge difference in the accuracy rates and the performance between both population groups from Germany itself, considering that Inden and Lübeck samples share the same ancestry. The accuracy rates improve with the exclusion of ambiguous individuals.

New species of the genus Philotella Najt amp; Weiner, 1985 (Collembola, Neanuridae, Pseudachorutinae) from the Russian Far East.

Eight new species of the genus Philotella, i.e. P. pax sp. nov., P. oligotricha sp. nov., P. cedrina sp. nov., P. aliniensis sp. nov., P. amurica sp. nov., P. alba sp. nov., P. pallida sp. nov., and P. caeca sp. nov., are described based on extensive ecological samplings conducted by specialists of the Department of Zoology and Ecology, Moscow State Pedagogical University, in various parts of the Russian Far East. Three previously known species were transferred from the genus Micranurida to Philotella to become P. grana (Lee Kim, 1984) comb. nov., P. porcella (Fjellberg, 1985) comb. nov. and P. japonica (Tamura, 1998) comb. nov. The main diagnostic features of the genus and its differences from the most similar genera of the subfamily Pseudachorutinae are discussed, and a regional key for identifying the Eastern Palearctic species of the genus is given.
