Comparative analysis of the efficiency of application of different methods of tillage in the system of resource-saving agriculture technologies
Authors: Chernogaev Vitaly G. , Svirina Vera A. 
Published: January 2021

Relevance. The article presents a comparative analysis of methods of basic tillage-classical dump plowing and technologies of minimal and no-till tillage. Question about the benefits of minimum and zero tillage on intensive up to the present time remains controversial. However, minimum and zero tillage systems are becoming increasingly common in the world as a response to increasing degradation and reduced soil productivity.Methods. Various publications on this topic were analyzed. Various studies show mixed results.Results. The analysis shows the following advantages of minimum and zero processing: costeffectiveness; prevention of soil erosion; maintaining fertility in the upper soil layer; preservation of soil moisture and vertical soil structure. The use of resource-saving technologies can not only preserve soil fertility and reduce the economic costs of its cultivation, but also prevent the degradation of farmland caused by erosion processes. Resource-saving technologies mean not only the abandonment of annual moldboard plowing, but also leaving crop residues on the field, the use of integrated weed control measures, the use of scientifically based crop rotations. Failure to meet these conditions will negate the effectiveness of minimum tillage. Minimum processing continuity is of particular importance. Any soil cultivation in the transitional phase means a return to the initial phase, and this should not be allowed. To ensure high productivity of resource-saving technologies, it is necessary to apply a well-grounded crop rotation system. An important factor in the use of resource-saving technologies in agriculture is economic efficiency. As experience shows, at the same yield level (20 cwt / ha), profitability with resource-saving technologies reaches 93.7%, while with a usual one — 55.4%. A comparative analysis of the methods of basic tillage shows that the advantages of minimal and no tillage are possible only in the presence of a high culture of agriculture. These advantages are as follows: cost-effectiveness; prevention of soil erosion; maintaining fertility in the upper soil layer; preservation of soil moisture and vertical soil structure.

Relevance. Recently, the number of many breeds and lines of chickens has significantly decreased, while others are under threat of extinction. Reducing the genetic resources of chicken’s worldwide limits the possibilities of future breeding programs. The study of the genetic diversity of the species allows you to more accurately manage the productive and potential of chicken breeds, the possibilities of its use for obtaining Biosafety and full-fledged food. Adding exterior estimation data to the bird breeding value forecast increases its accuracy and is relevant.Methods. The study was conducted on chickens of two experimental populations «Experimental CS» meat-egg of productivity and «Experimental LZS» egg-meat productivity from the Genetic collection of rare and endangered chicken breeds Russian Research Institute of Farm Animal Genetics and Breeding — Branch of the L.K. Ernst Federal Science Center for Animal Husbandry.Results. The highest absolute increase in live weight of chickens is observed in the period of 4-8 weeks, and the relative increase at the age of 4 weeks, regardless of the type of productivity of chickens. The results of cultivation largely depend on the intensity of growth of the bird in the early period, up to four weeks of age. The superiority of the meat-egg population in comparison with the egg-meat population was revealed in terms of breast circumference (5.0–7.7%).

Published: January 2021

Relevance and methods. The efficiency of obtaining and reproduction of hybrid animals is closely related to their reproductive performance during interspecific hybridization. Hybrid males often have low fertility. In this regard, it is necessary to carry out the procedure for the preparation of semen for further use. The aim of the research was to study the effectiveness of using the flotation method (swim-up) to improve the quality of the sperm from hybrid males. The object of the study was the sperm from hybrids of argali with Romanov breed ewes (1/8 argali x 7/8 Romanov breed, n = 15).Results. A comparative analysis of the qualitative and quantitative indicators of freshly obtained, frozen-thawed and processed by the swim-up method was carried out. The sperm freeze-thaw cycle was accompanied by an increase in the sperm DNA fragmentation index and an increase in the proportion of immotile spermatozoa by 10% and 37%, respectively, compared with freshly obtained semen. The number of sperm with abnormal morphology doubled. Using the procedure «swim-up» possible to increase the content of the progressive motile sperm by 2.1 times compared with that established for the frozen-thawed sperm (p ≤ 0,01). The obtained results indicated the effectiveness of using the “swim-up” procedure to improve the quality of the semen from interspecific hybrid males.

Published: January 2021

Relevance. Agro climatic conditions play a decisive role in the formation of the yield of the green mass of sainfoin. Therefore, knowledge of the mechanism of the relationship between the plant and the external environment is relevant.Materials and methods. The experiment was carried out in 1971–2020 in the department of agriculture at the Prikumskaya experimental selection station. The aim of the research was to identify the influence of some agro meteorological factors on the yield of sainfoin on green fodder in the arid conditions of the Stavropol Territory.Results. Analysis of meteorological factors over 50 years of research indicates the cyclical nature of their development in time. At the same time, a steady increase in the average annual air temperature (1.2 °C) and the annual sum of active temperatures (248 °C) was revealed. The entire growing season from April to October is dry (Hydrothermal Moisture Coefficient = 0.69), but the driest period is from July to October (Hydrothermal Moisture Coefficient = 0.55). The size of the green mass of sainfoin yield mathematically reliably depends on the amount of precipitation in August-May (r = 0.55), March-May (r = 0.47) and March (r = 0.40). The amount of precipitation in August-May in 16% of years was less than 250 mm, in 24% of years 251–301 mm, in 26% of years 302–352 and 353–403 mm and in 8% of years more than 404 mm. In March-May, in 74% of years, precipitation was 61–153 mm, in 20% of years more than 154 mm, and in March in 66% of years it dropped to 33 mm, in 22% of years 34–48 mm and in 12% of years more than 49 mm. Productivity depends not only on the amount of precipitation in the most crucial periods of ontogenesis, their distribution during the growing season, but also on many other factors. The range of yield variation with the same amount of precipitation in August-May was 13.74 — 34.11 t / ha.

O objetivo deste estudo foi avaliar a realização de atividade física e a qualidade de vida e observar suas possíveis correlações em pacientes oncológicos durante o tratamento quimioterápico. Trata-se de um estudo observacional, descritivo e transversal. A amostra foi selecionada por amostragem aleatória simples. Incluíram-se indivíduos maiores de 18 anos com diagnóstico clínico de neoplasia maligna que tivessem realizado no mínimo duas sessões de quimioterapia, podendo ou não estar realizando outro tratamento associado à mesma. A realização de atividade física foi avaliada através do questionário International Physical Activity Questionnaire (IPAQ) e a qualidade de vida através do questionário European Organisation for Research and Treatment of Câncer Quality of Life Questionnaire C30 (EORTC QLQ-C30). Foram estudados 38 indivíduos. No EORTC QLQ-C30, nenhum paciente atingiu a pontuação máxima de funcionalidade. Os sintomas “fadiga” e “dor” obtiveram alta pontuação. Em relação à realização de atividade física, 63,2% dos pacientes realizaram menos do que 297 equivalentes metabólicos (METs) e 36,8% realizaram mais do que 297 METs de acordo com a classificação do IPAQ. Os pacientes que realizaram mais do que 297 METs apresentaram uma melhor qualidade de vida do que os que realizaram menos do que 297 METs. Observou-se uma correlação entre o total de METs realizados e diversas escalas do EORTC QLQ-C30, como “estado geral”, “físico” e “fadiga”. A atividade física parece estar relacionada com diferentes aspectos da qualidade de vida de pacientes oncológicos. Assim sendo, programas regulares de exercício físico, talvez, sejam uma excelente estratégia para melhorar a qualidade de vida dos mesmos.

Purpose – Given the prevalence of mental health issues among young adolescents and its detrimental effects on academic functioning, Social- Emotional Learning (SEL) interventions are becoming extremely valuable. The current study aims to investigate the effectiveness of two types of SEL interventions delivered by two different types of teachers to determine their effectiveness for SEL knowledge, learning anxiety, and intention to drop-out. Methodology – This study employed a 2 x 2 factorial and between-subject quasi-experimental design, in which intervention type and teacher type were manipulated to produce four different versions of experiments. A total of 209 students (107 boys, 102 girls) from Grade 8 with a mean age of 14.3 years from Qinzhou City in Southwest China participated in the study. Findings – Factorial and between-group MANOVA revealed that while psychology teacher was more effective in enhancing SEL knowledge and reducing dropout intention, regular teacher was more effective in reducing learning anxiety. TASSEL intervention was more effective in enhancing SEL knowledge while SEL regular intervention was more effective in reducing learning anxiety. Nevertheless, within-group analysis suggested TASSEL with psychology teacher was the best combination in reducing dropout intention while SEL with psychological teacher was the best combination in reducing learning anxiety. Significance – The results have significance for schools and mental health counselling services. The findings can guide the effective design of SEL intervention and appropriate teachers to deliver it.

Anodized aluminum oxide (AOA) is applied in many technological areas such as formation of decorative or anticorrosive coating, hydrophobic and hydrophilic surfaces, development of functional micro- and nanomaterials. Due to unique properties of porous structure (most direct, regular and through pores with size in a narrow range) AOA films can be used for membrane separation. The morphological features of such films mainly depend on synthesis conditions. This review consists of the models of pore formation on the aluminum surface and the correlation parameters of films with anodizing conditions. Particular attention is paid to the influence of synthesis factors (electrolyte composition, voltage, temperature conditions, etc) on the porous structure of AOA and the film thickness that determines the mechanical strength of membranes. The optimal voltage values for the porous structure arraingment of anodized aluminum oxide were indicated for each electrolyte. It is noted formation of cylindrical shaped pores with controllable pore diameters, periodicity and density distribution can be produced during two-stage anodizing. The pre-treatment of the metal surface and stage of separation of the formed film from its surface are also considered. Modern research are mainly aimed to synthesis of porous AOA membranes in new anodizing electrolytes and determining pore formation factors on the aluminum surface. The new anodizing conditions in most popular electrolytes (oxalic, sulfuric, phosphoric acids) for obtaining of porous AOA with the required morphological features is also under investigation. Such conditions include, for example, a lower voltage or higher temperature in case for a particular electrolyte. To avoid of local heating the electrolytes with additional components, for example, organic additives is also studied. Some practical aspects of AOA membrane utilization obtained under certain conditions are considered.

Citizen science is gaining popularity as a way to engage people to participate in environmental projects. In addition to potential challenges regarding data quality and the choice of variables, a key factor in the success of participatory monitoring projects is the active participation of volunteers, the “citizen scientists.” To learn more about the motivation of citizen scientists to participate and their socio-economic background, a telephone survey was implemented with participants of a citizen science water level monitoring program in the Sondu-Miriu basin, western Kenya. We analyzed the data using descriptive statistics and random forest models to elucidate the characteristics of the participant population, underlying motivations, and the challenges and opportunities to develop recommendations for sustainable community-based water monitoring programs. As citizen scientists who engaged long-term were 30–49 years old, had primary or secondary school education and passed by the monitoring station frequently, targeting sensitization activities at people with such background could increase participation in community-based water monitoring. Sensitization meetings were key in engaging long-term volunteers, but participants indicated that continued feedback through education and communication of the project findings is required to keep volunteers motivated. The use of cellphone credit to submit data was identified as challenge for participation, highlighting the need for data submission methods that do not incur costs for the participants. Greater volunteer support could also be achieved by active involvement of the members of Water Resource Users Associations, since membership increased the likelihood of continuous engagement in water monitoring under the participants. Furthermore, many participants indicated that their motivation was to help water management and conservation, as most people rely directly on rivers for their water supply. Providing a platform to contribute to better water resources management could therefore result in direct benefits (e.g., improved water supply) for the participants, and thus an incentive to participate actively.
A Stem Cell Surge During Thyroid Regeneration
Authors: Ma Risheng , Morshed Syed A. , Latif Rauf , Davies Terry F. 
Published: January 2021

BackgroundMany tissues, including the thyroid, contain resident (adult) stem cells that are responsible for regeneration and repair after injury. The mechanisms of thyroid regeneration and the role of thyroid stem cells and thyroid progenitor cells in this process are not well understood. We have now used a new mouse thyroid injury model to gain insight into this phenomenon.MethodsTamoxifen induced TPO-Cre mice (TPOCreER2) were crossed with inducible Diphtheria Toxin Receptor homozygous mice (ROSA26iDTR) to give rise to TPOCreER2/iDTR mice, allowing for the Cre-mediated expression of the DTR and rendering TPO expressing thyroid cells highly sensitive to diphtheria toxin (DT). This model of TPOCreER2/iDTR mice allowed us to study the repair/regeneration of thyroid follicles after diphtheria toxin induced thyroid damage by measuring serum thyroid hormones and cell fate.ResultsIn TPOCreER2/iDTR double transgenic mice we observed severe thyroid damage as early as 2 weeks after initiating intraperitoneal DT injections. There was marked thyroid tissue apoptosis and a ~50% drop in serum T4 levels (from 5.86 to 2.43 ug/dl) and a corresponding increase in serum TSH (from 0.18 to 8.39 ng/dl). In addition, there was a ~50% decrease in transcription of thyroid specific genes (thyroglobulin, TSH receptor, and sodium-iodide symporter). After suspending the DT administration, the thyroid rapidly recovered over a 4-week period during which we observed a transient surge in stem cell marker expression (including Oct4, Nanog, Sox2, and Rex1). In addition, cells immunostaining with stem cell markers Oct4 and Ssea-1 were found in clusters around new thyroid follicles in TPOCreER2/iDTR double transgenic mice. Furthermore, the presence of clusters of thyroid progenitor cells was also identified by Pax8 staining of thyroglobulin negative cells. This recovery of the injured gland was followed by a rapid and sequential restoration of thyroid function.ConclusionThese data demonstrate that a new model of thyroid cell damage induced by DT can be used to study the mobilization of resident adult stem cells. Furthermore, the model clearly demonstrates the involvement of both stem and progenitor cells in the in vivo regeneration of the thyroid after severe destruction.

Non-destructive testing (NDT) is not only primarily concerned with the detection of discontinuities, but also with the mechanical properties. However, the usage of NDT in understanding the mechanical effect that leads to a failure of composites and the damage mechanisms are still not thoroughly studied, as much of the NDT approaches are widely used to maintain the structural integrity to preserve quality assurance. This work aims to investigate the application of infrared thermographic and ultrasonic in evaluating randomly-oriented short-natural-fiber-reinforced phenolic composites. The composites were made from short palm fibers of various sizes between 1.18–0.6 mm, 0.6–0.3 mm, and less than 0.3 mm at 20 and 40 wt%, respectively. The tensile results obtained from the parallel testing of the composites using infrared thermography, where the temperature and time changes on the tested samples were continuously recorded. The peak in the temperature-time graph indicated a macro crack growth and matrix cracking in the form of dissipated energy. Ultrasonic inspection were carried out on the impacted specimens. A scan of the ultrasonic testing on the phenolic composites found presence of a back wall in neat phenolic and was eradicated with fiber reinforcement due to attenuation and energy dissipation. The attenuation coefficient of composites was calculated with the aid of the A-scan. Therefore, it is concluded that ultrasonic inspection on the natural fiber is limited due to the large scattering of wave and energy loss due to attenuation, while infrared thermography is suitable to inspect natural-fiber-reinforced composites when monotonic loadings are applied.
