"Цель данной статьи исследовать и определить, какой из наиболее распространенных и востребованных современных языков программирования лучше всего подходит для решения научно-технических задач с использованием консольного интерфейса, национальных алфавитов и специальных символов. Материалом исследования будут входные и выходные символьные данные, а методом исследования будет разработка специального программного обеспечения и тестирование на нем входных материалов. Специальное программное обеспечение для исследования будет представлять собой разработанные четыре тестовые программы, т.е. одна программа для одного языка программирования. Каждая тестовая программа должна быть способна вводить и выводить строковые данные, содержащие символы национальных алфавитов (например, русского, английского, китайского) и специфические научно-инженерные символы. Проведенные тесты показали, что только языки программирования Python и C# умеют нормально работать с символами Unicode в консольных программах под ОС Windows. Языки программирования C/C++ и Java имеют проблемы с отображением национальных алфавитов и спецсимволов и не могут быть рекомендованы для разработки научно-практических программ в консольном исполнении под ОС Windows. Анализ данных показывает, что предпочтение стоит отдать языку программирования Python. Данный язык программирования очень прост для освоения, в нем очень много готовых библиотек для научно-технических расчетов, а также есть много бесплатных профессиональных сред для разработки программ. Если же для работы предполагается использовать в основном ОС Windows и иметь оконный интерфейс у разрабатываемых программ, то стоит воспользоваться языком C#. Ключевые слова: язык программирования, кодировка, символы, операционная система, консоль. "

"One of the factors that determine the safety of electrical installations in ungrounded AC systems is the insulation resistance to earth. Early recognition and fault clearance, accompanied by a change in the active and reactive components of the insulation conductivity in ungrounded AC systems, will ensure work safety in electrical installations. Due to the fact the scale of cases of electrical injuries continues to remain significant, despite the tightening of the requirements of regulatory and technical documentation and the creation of newer effective methods and protection equipment against electric shock, therefore, increasing the level of electrical safety in the operation of mining machines and complexes is an urgent task. The article depicts the results of the approbation of the developed method for determining network insulation parameters on an operating excavator. The developed method is based on measuring phase voltages and angles of their vectors before and after connecting an additional capacitance to the phase of the electrical network and to the earth. According to the developed method, numerical data of the insulation condition in an electrical network with a voltage up to 1000 V and the single-phase earth fault current were calculated. During the approbation of the developed method, the lack of the existing protective residual current device was identified. Keywords: network insulation, admittance, susceptance, neutral shift, zero-sequence voltage. "

Breast cancer is a major public health concern worldwide. The incidence of breast cancer remains high. The mortality rate and prognosis for breast cancer can be improved with early diagnosis and therapy. Self-examination of the breasts is a common method of early diagnosis for women's health issues. This study aimed to explore the characteristics of female students in Allied Health Sciences Institution who performed regular breast self-examination in Indonesia and Pakistan. After institutional ethics review board approval and informed consent, a quantitative survey recruited 430 female students from Allied Health Sciences institutions in Indonesia and Pakistan. This study strictly followed the highest level of ethical standards proposed by Helsinki Declaration (Revised 2013). A closed and open-ended questionnaire was used to collect data on their demographics and characteristics. The questionnaire was distributed online using a google form. Data were analyzed using descriptive analytics . The findings of this study showed that n=395(91.86%) were aged 18-35 years, and 51% were from rural. 49% from urban areas. The majority of participants were single or never married (88%). Most participants were undergraduate students (95.35%). Almost half participants did routine BSE once a month (48.6%). Only 16% were very confident about doing a breast self-examination. Nearly half respondents had never seen a doctor (47%).  A positive attitude was seen among all the students. Additionally, most students performed a weekly breast examination. Evidently, more than half of the participants lacked self-assurance when it came to performing a breast assessment. We found a significant percentage who had never been to a doctor for medical attention. Public campaigns to raise awareness and urge female student in allied health science to regularly see their doctors and engage in BSE are so crucial

Published: May 2023

El objetivo de esta investigación fue determinar la capacidad de los Modelos de Identidad Social Movilizada (MISM) y de Motivos Psicosociales (MMP) para explicar la participación en acciones de protesta social regionalista en Chile. Se aplicó una encuesta a una muestra representativa de 1200 personas mayores de 18 años de cuatro regiones del país. Los resultados de los análisis de regresión lineal múltiple indicaron que el MMP tiene mayor capacidad predictiva que el MISM (36% versus 4.9% de la varianza explicada). En el MMP son especialmente relevantes los motivos de objetivo y los motivos sociales. La identificación con la región no permite predecir la participación en protestas regionalistas, a diferencia del valor subjetivo otorgado a los objetivos de la movilización que aparece altamente asociado a la participación en ésta. Se discute la importancia del estudio de las redes sociales primarias para explicar la conducta de protesta social.

Aims: The interruption of blood flow to the heart muscle is called a heart attack. During a heart attack, the risk of permanent damage increases with every second the heart tissue cannot receive enough blood. If early and appropriate intervention is not performed, loss of heart tissue occurs. Causes such as smoking, cholesterol, diabetes, high blood pressure, old age, obesity, genetics, and high levels of certain substances produced in the liver are the main risk factors for heart attack. This study aims to predict the risk of heart attack with machine learning methods using a dataset created by considering risk factors.
Methods: The performances of three types of Linear Discriminant Analysis classifiers, Normal, Ledoit-Wolf, and Oracle Shrinkage Approximating, were compared on the Cleveland dataset.
Results: Normal Linear Discriminant Analysis made the best classification with 83.60% accuracy and performed better than regularized versions.
Conclusion: Linear Discriminant Analysis methods are a promising classifier for heart attack prediction and can be applied in hospitals as an objective and automated system that eases specialists' workload and helps reduce diagnostic costs.

Biomechanics, pathomechanics, diagnosis, treatment, and return to play criterias of lateral ankle sprains: an evidence-based clinical guideline
Authors: KARARTI Caner , Özyurt Fatih , BASAT Hakkı Çağdaş
Published: May 2023

Lateral ankle sprain (LAS), which is common in recreational and professional athletes, recurs and becomes chronic if left
untreated. Since the number of mechanoreceptors it contains is high, LAS should not be considered only as a musculoskeletal disorder. A detailed clinical evaluation is recommended. Clinically, the patient presents with limitation of dorsiflexion range of motion (ROM), muscle atrophy and unequal strength between the muscles, deterioration in walking, running and jumping, and proprioceptive losses. The patient should be approached from a biopsychosocial perspective both in the evaluation and treatment phases. The treatment of the patient is carried out in 3 phases and the transition between phases should be based on mentioned criterias. In the acute phase of rehabilitation, emphasis should be placed on eliminating pain and edema, and preventing loss of ROM and muscle strength. In the subacute and chronic stages, emphasis should be placed on increasing the proprioceptive sense and muscle strength, improving the biomechanics of daily life and sports-specific movements such as walking, running, jumping. If the patient is an athlete, return to sports should be planned after the criterias met.

Published: May 2023

Oats is one of the most important grain crops, versatile use. After many years of observations on the cultivation of oats, it was found that spring oats have higher productivity than naked varieties. The reason for the low productivity of these varieties is the capriciousness of its cultivation. In order for the grains to ripen evenly, a large preparation of soil and fertilizers is required, a nutrient and air-water regime is selected. Despite all the shortcomings, in recent years, oats have become the main product in proper nutrition, which is why the demand for naked oats has increased. According to scientists, these varieties have a positive effect on the human body.

Numerical investigation on measurement errors of mixing states of fractal black carbon aerosols using single-particle soot photometer and the effects on radiative forcing estimation
Authors: Liu Jia , Wang Guang-ya , Zhu Can-can , Zhou Dong-hui , Wang Lin
Published: May 2023

Abstract. The mixing state of black carbon (BC) aerosols can be measured by the single-particle soot photometer (SP2). However, the measured mixing state contains errors, because the core-shell model and Mie scattering calculation are employed in the measurement principle of SP2, and the spherical core-shell structure seriously deviated the real morphology of coated BC. In this study, fractal models are constructed to represent thinly and heavily coated BC particles for optical simulations, the scattering cross-section are selected as reference to conduct optical retrieval of particle diameter (Dp) based on Mie theory, just like the measurement principle of SP2, and the diameter of BC core (Dc) are the same for fractal and spherical models. Then, the measurement errors of mixing state (Dp / Dc) of BC are investigated from numerical aspect, and the estimation accuracy of BC radiative forcing is analyzed through the simple forcing efficiency (SFE) equation with SP2 measurement results taken into consideration. Results show that SP2 measured Dp / Dc based on Mie theory underestimates the realistic mixing state of coated BC for most particle sizes, and the largest relative error for single-particle can be about 42 %. The retrieval errors of mixing state of thinly coated BC for both single-particle and particle groups are larger than these of heavily coated BC. In addition, evaluation errors of radiative forcing of coated BC caused by measurement errors of SP2 are up to about 76 % and 43 % at 1064 and 532 nm, respectively. This study provides meaningful referential understandings of the measured Dp / Dc of SP2.
An ensemble method for improving the estimation of planetary boundary layer height from radiosonde data
Authors: Chen Xi , Yang Ting , Wang Zifa , Wang Futing , Wang Haibo
Published: May 2023

Abstract. The planetary boundary layer (PBL) height (PBLH) is an important parameter for both weather, climate and air quality models. Radiosonde is one of the commonly used instruments for PBLH determination and is generally accepted as a standard for other methods. However, mainstream approaches for the estimation of PBLH from radiosonde present some uncertainties and even show disadvantages under some circumstances and the results need to be visually verified, especially during the transition period of different PBL regimes. To avoid the limitations of individual methods and provide a benchmark estimation of PBLH, we propose an ensemble method based on high-resolution radiosonde data collected in Beijing in 2017. Seven existing methods including four gradient-based methods are combined along with statistical modification. The ensemble method is verified during afternoon, morning, and evening transition periods, respectively. The overestimation of PBLH can be effectively eliminated by setting threshold for gradient-based methods and the inconsistency between individual methods can be reduced by clustering. Based on the statistics of one-year observational analysis, the effectiveness of the ensemble method reaches up to 70.8 %, an increase of 14.7 % ~ 61.2 % compared with the existing methods. Nevertheless, the ensemble method suffers to some extent from uncertainties caused by the removal of truly high PBLH, the profiles with a multi-layer structure, and the intermittent turbulence in the stable boundary layer (SBL). Finally, this method has been applied to characterize the diurnal and seasonal variations of different PBL regimes. Particularly, the average CBL height is found to be the highest in spring and the SBL is lowest in summer with about 200 m. The average PBLH at transition stage lies around 900 m and there is no obvious seasonal variation. The findings imply the effectiveness of the ensemble method.
Recent inorganic carbon increase in a temperate estuary driven by water quality improvement and enhanced by droughts

Published: May 2023

Abstract. Estuaries are an important contributor to the global carbon budget, facilitating carbon removal, transfer and transformation between land and coastal ocean. Estuaries are also susceptible to global climate change and anthropogenic perturbations. We find that a long-term significant increase in dissolved inorganic carbon (DIC) of 6–21 µmol kg-1 yr-1 (1997–2020) in a temperate estuary in Germany (Elbe Estuary), was driven by an increase in upper estuary particulate organic carbon (POC) content of 8–14 µmol kg-1 yr-1. The temporal POC increase was due to an overall improvement in water quality observed in the form of high rates of primary production and a significant drop in biological oxygen demand. The magnitude of mid-estuary DIC gain was equivalent to the increased POC production in the upper estuary, suggesting that POC is efficiently remineralized and retained as DIC in the mid-estuary, with the estuary acting as an efficient natural filter for POC. In the context of the significant DIC increase, the impact of a recent extensive drought period (2014–2020) significantly lowered the annual mean river discharge (468 ± 234 m3 s-1) compared to the long-term mean (690 ± 441 m3 s-1, 1960–2020). During the drought period, the late spring internal DIC load in the estuary doubled. This suggests that the drought induced a longer dry season, starting in May (earlier than normal), increased the residence time in the estuary and allowed for a longer remineralization period for POC. Annually, 77–94 % of the total DIC export was laterally transported to coastal water, reaching 89 ± 4.8 Gmol C yr-1, and thus only a maximum of 23 %, at 10 Gmol C yr-1, was released via carbon dioxide (CO2) evasion, between 1997 and 2020. Export of DIC to coastal waters decreased significantly during the drought (2014–2020: 38 ± 5.4 Gmol C yr-1), on average by 24 % compared to the non-drought period. In addition, we have identified that seasonal changes in DIC processing in an estuary require consideration in order to understand both the long-term and future changes in air-water CO2 flux, DIC export to coastal waters, as well as the impacts of prolonged droughts on the land-ocean carbonate system.
A two-folds deep learning strategy to correct and downscale winds over mountains

Published: May 2023

Abstract. Assessing wind fields at a local scale in mountainous terrain has long been a scientific challenge partly because of the complex interaction between large-scale flows and local topography. Traditionally, the operational applications that require high resolution wind forcings rely on downscaled outputs of numerical weather predictions systems. Downscaling models either proceed from a function that links large scale wind fields to local observations (hence including a corrective step), or use operations that account for local scale processes, through statistics or dynamical simulations, and without prior knowledge of large scale modeling errors. This work presents a strategy to first correct and then downscale the wind fields of the numerical weather prediction model AROME operating at 1300 m grid spacing, by using a modular architecture composed of two artificial neural networks and the DEVINE downscaling model. We show that our method is able to first correct the wind direction and speed from the large scale model (1300 m), and then accurately downscale it to a local scale (30 m) by using the DEVINE downscaling model. The innovative aspect of our method lies in its optimization scheme that accounts for the downscaling step in the computations of the corrections of the coarse scale wind fields. This modular architecture yields competitive results without suppressing the versatility of the downscaling model DEVINE, which remains unbounded to any wind observations.

The laundry business is one of the household-scale businesses that is currently developing in Jambi City. This is possible because the number of laundry business customers is increasing along with the increase in the population in the city of Jambi and the increasingly diverse activities of the people of the city of Jambi. The laundry business in Jambi City is more than 300 units, so if the laundry waste is not treated first, it will have the potential to cause environmental pollution because of the compounds it contains. This study aims to determine the efficiency of the electrocoagulation process to decrease parameters in laundry wastewater, while the parameters observed are pH, COD (Chemical Oxygen Demand), and Phosphate (PO4). Cause pollution to the surrounding environment, especially in receiving water bodies. Variable voltage (voltage) in the electrocoagulation process is 9 volts, 12 volts, and 15 volts with a reactor capacity of 12 liters with a time of 30 minutes and 60 minutes at each voltage. Decreasing parameters were analyzed by comparing pH, COD (Chemical oxygen demand), and Phosphate (PO4) before and after the study, as well as the effect of voltage (voltage) and contact time on the effectiveness of decreasing parameters. The highest percentage of COD reduction efficiency is 80%, Phosphate Parameter is 92%. Voltage (voltage) and contact time also affect the results of parameter removal.

Between conflict and cooperation: The Contrasting image of the Ottoman Turks in Late Medieval Ragusan Sources
Authors: Filipović Emir O.
Published: May 2023

The present study focuses on the late medieval commune of Dubrovnik, known in Latin and Italian sources as Ragusa, and its precarious relationship with the Ottoman Turks, while placing a particular emphasis on the various strategies that Ragusans employed throughout the fourteenth and fifteenth centuries in attempting to navigate a difficult political existence between their own interests and the interests of a unified Christendom which stood in complete opposition to the Ottomans. Numerous surviving records created in Ragusa at the time depict the Ottoman Turks in a completely inconsistent light, demonstrating that historians, as always, need to take particular care about accepting claims from diplomatic sources at face value, and that relations between Christians and Muslims during the Ottoman conquest of the Balkans were not always as unambiguous or constantly hostile as they are often presented to be in contemporary works, modern historiography and public discourse.
Artificial lighting technologies to support aquatic plants in rivers which are shaded by bridges and culverts
Authors: Fleming Simon D. , House Tom M. , Boyd Justin K. , Lavelle Anna M. , German Sally E.
Published: May 2023

Aquatic plant communities are important components of river ecosystems, providing food sources and functional habitats through the provision of refuge and spawning substrate for animals including fish and macroinvertebrates. Types of urban infrastructure including bridges and culverts present a major challenge to rivers; for example, the shading effects of these structures can exclude aquatic and wetland plants, degrade and fragment habitats and inhibit the movement of aquatic and riparian species in rivers. Few studies have investigated the potential to reconnect riverine habitats through artificial lighting technologies. In this study, a 12-month controlled laboratory trial was undertaken to investigate the potential for using artificial lighting to support aquatic plants shaded by urban infrastructure. Two artificial lighting scenarios were compared to a natural light (control) scenario to determine the potential for supporting eight aquatic plant species common in UK rivers. Overall, growth rates, flower numbers and biomass values were higher for all species under the natural light scenario. However, the artificial lighting scenarios also enabled selected plants to grow and survive over the trial period with variable success in line with shade tolerance, suggesting that it is feasible to grow aquatic plants under urban infrastructure using artificial lighting. This study provides a basis of understanding on how to design an artificial lighting strategy that can support a community of aquatic plants; however, further study and in river trials are required to optimise such as system.
New York's Directive for Mental Health Involuntary Removals: The Intersectional Risk for Unhoused New Yorkers with a Serious Mental Illness
Authors: Snyder Lanya
Published: May 2023

Behavioral health care, more commonly known as psychiatric care, has been a longstanding and complex issue, especially for marginalized New Yorkers. Healthcare policy addressing and caring for people diagnosed with a serious mental illness is fundamental to basic human rights; at the same time, it is a nuanced matter. Policies surrounding economic issues of poverty and housing instability are inextricably linked to social issues of mental and physical healthcare.

Healthcare policy and the experience of homelessness are closely linked for two reasons: first, the high cost of healthcare contributes to poverty for many Americans; and second, the poor and the aging are the most likely to suffer from illness and high medical expenses (Martin, 2015). This paper will consider the intersectional risk for unhoused New York City residents with a serious mental illness in light of Mayor Eric Adams’ recent directive for Mental Health Involuntary Removals. This new directive enables authorities to forcibly transport unhoused New Yorkers to hospitals to remove them from public areas. Although the current mayoral administration frames this as a moral obligation to act on behalf of New Yorkers with a serious mental illness, it is far from an effort to ensure that everyone has housing and receives basic healthcare. Adams’ misguided policy is a veiled attempt to make the city appear safer while doing little to assist those who are suffering and fails to address interventions for the real issue at hand: housing.
"Small Victories of Survival in a Deeply Homophobic World": Current Realities and Paths Forward for Substance Use in the LGBTQIA+ Community
Authors: Orchard Kate
Published: May 2023

According to the National Institute on Drug Abuse, members of the LGBTQIA+ community are disproportionately impacted by problematic substance use (National Institute on Drug Abuse, 2020). Despite this well-documented reality, there is still limited funding and access to substance use treatment for queer and trans people. This exploratory paper surveys the literature on the prevalence of substance use in the LGBTQIA+ community in the United States (US), highlighting the historical and cultural realities leading to this trend within the context of the minority stress model. The article then outlines a path forward, suggesting the best treatment models for social workers in the field. Suggestions include integrated healthcare, trauma-informed, LGBTQIA+-specific treatment models, cognitive behavioral therapy focusing on co-occurring Post-Traumatic Stress Disorder (PTSD) and substance use disorder, harm reduction, and crisis intervention outside of policing.
Choosing a Frame: How Medusa Tells the Story of Trauma and Life After Trauma
Authors: Yurman-Whyde Ezra
Published: May 2023

This paper names the elements of the Medusa myth that make it an uncanny allegory for trauma and examines the role of choice—both having choice and offering choice—in the treatment of trauma. It considers two perspectives on the myth: (1) Medusa as a captive object to the hero in the myth and (2) Medusa as an autobiographer, the narrator of her own story, and a subject working to establish more control over her own experience. This myth translates to the social work space. When a clinical social worker acts as the listener/observer and a patient as narrator/autobiographer, the social worker is uniquely positioned to support the patient in reclaiming life after trauma.
Disability and Self: Critical Factors in Positive Adjustment After the Onset of Disability in Emerging Adulthood
Authors: Christensen Natalie
Published: May 2023

Resiliency, self-efficacy, and social support are key factors influencing adjustment following the onset of chronic disability. The presence or absence of these factors influences the affected person’s perceptions of self, perceptions by others, and overall life satisfaction and confidence in their ability to achieve goals. This article assesses data collected from an open-ended interview with a single participant, D, organized by thematic analysis. It finds that D's resiliency, self-efficacy, and social support system significantly influenced her mindset and attitude toward life after being diagnosed with Multiple Sclerosis (MS). The author explores how these factors were influenced by the micro-, meso-, and macro-contexts in which D existed, focusing particularly on the context of her relationships with others. The paper concludes with recommendations for future research.

Food security of the population is one of the main challenges of the 21st century, which, due to the events of recent years (Artsakh war, pandemic, Russian-Ukrainian conflict, sanctions, export restrictions) and their consequences, has become more acute. The stability of the grain sector in the country is of particular importance from the point of view of improving the food security in Armenia. Based on the study of international practice of state support for agricultural production, the results of analysis on the effectiveness of the state support tools traditionally used in different countries, as well as evaluating the state support for the development of grain production in RA, we have developed a model of state regulation of grain production, where the application of a number of realistic methods and measures is emphasized.
The results of the studies document that, despite the government’s efforts to expand grain production, the grain sown areas are decreasing year by year, yield growth is not ensured, and the total growth is decreasing. Studying the international experience of state support for agricultural production, analyzing the results of the effectiveness of the state support tools traditionally used in different countries, as well as evaluating the state support for the development of grain production in RA for 2010-2021, we propose to revise the state regulation tools.
In particular, to create a grain commission, form a guarantee and collateral price institute, set grain production and distribution quantities, strengthen contractual relations, form a commodity credit company and a grain price stabilization fund, apply
commodity intervention, as well as promote economy-infrastructure intervention.
We believe that the mentioned fundamental measures will contribute to the prospective development of grain production, ensure realistic results in the medium term, strengthen the cooperation between the state, production and science, as well as increase the self-sufficiency level of grain and, most importantly, will contribute to ensuring the food security of the Republic of Armenia.

Throughout the current research 20 rare plant species of the RA mountain meadow zone has been studied and the botanical, topographical, cartographical and graphical descriptions have been compiled based on the existing spatial database.
At the first research phase, three rare plants growing in the regions of Kotayk and Gegharkunik were mapped in the ArcGIS environment: Inula acaulis Schott & Kotschy ex Boiss., Acanthus dioscoridis and Draba araratica Rupr. For mapping, first their distribution per communities, settlements, operational significance and soil type was studied and identified, then digital mapping and analysis were performed in the GIS (Geographic Information Systems) environment. Based on the results, it was recommended to take appropriate measures for their preservation.
Further changes in the ecological condition of rare plants growing in the selected regions were studied, maps of the given areas were drawn up in the GIS environment, and analysis of plant location, growth density, distance from the settlement,
functional significance of the land, threats of extinction as a rare plant species, and conservation measures was performed.
The received digital maps and analysis of mapping results justify the need for the development of additional measures (legal, economic, environmental). In order to map the mentioned plant species in ArcGIS environment, sequence of actions has been developed based on which it is possible to update, adjust and complete the database of rare plant species in the mountain meadow zone of Armenia and enrich the global biodiversity repository through the GBIF system.

The implemented research was aimed to evaluate the biological and economic indicators of the studied varieties of zucchini, to introduce the most valuable and high-yielding variety into production.
Expert studies were conducted in 2021-2022 in the Taghavard community of the Martuni region of the Republic of Artsakh, located at an altitude of 600m above sea level. Anna (control), Adana and Zartonk zucchini varieties were studied. Each cultivar was planted in a 50 m2 plot with four replications. In each plot, 123 plants were planted in two rows of 10 m length, with 90+70 cm inter-row and 45 cm inter-plant distance. During the vegetation period, feeding with the norm of N 45 was done twice. Breeding varieties were evaluated according to growth and development stages, duration of vegetation, resistance to diseases and pests, and yield indicators. According to research, the Adana and Zartonk have a relatively long vegetation period (72 and 73 days), and the Adana (510 cent/ha) stands out in terms of crop structural elements and yield indicators. Adana and Zartonk are relatively resistant to diseases, and the difference in pest infestation is insignificant.
Adana surpassed both Anna and Zartonk in terms of fruit percentage. It exceeded the high-yield control by 135 cent/ha, at the same time, with high economic efficiency, it provided 135 cent/ha crop addition and AMD 420.000 additional profit per hectare.
It is recommended to cultivate the Adana zucchini variety in the sub-mountainous zone of the Artsakh Republic.

Milk is a good source of protein, calcium, vitamins, magnesium, casein. Its advantages are the pleasant taste, dietary features and the ability to quench thirst. However, in hygienic terms, it is not without drawbacks. In particular, milk is a beneficial environment for the development of various microorganisms, including pathogens, as a result of which it can easily become a carrier of infectious diseases. Therefore, the task was set to investigate the risks associated with the transmission of a number of dangerous zoonotic infectious diseases, in particular brucellosis and tuberculosis.
To this end, organoleptic and laboratory studies were carried out on 20 samples of unpasteurized milk purchased from private individuals in different administrative districts of the city of Yerevan.
Through organoleptic method the color, smell, taste, texture of milk was determined. Under laboratory conditions, pH, purity, density, total acidity, bacterial contamination of milk and the presence of brucellosis antibodies and causative agents of tuberculosis were detected. Milk samples were also examined for starch and soda content (milk adulteration).

Throughout 121 days of winter pasture period, the animals aged 9.0-12.9 months old were grazed on without supplemental feeding.
The study was carried out in the winter pasture of Yeghegnut community, Armavir region of RA. 10 heads from Holstein and Flekvi heifers each, kept in stalls were selected for the research. During 121 days of winter grazing, female calves from 9.0 to 12.9 month-old were in the pasture from 12:00 to 17:00 and during the remaining 19 hours in the cattle shed, without additional feeding.
Absolute, average daily, relative weight gain and growth factors were determined on the basis of weighing and body part measurements at the beginning and end of winter grazing.
According to the weight growth data, the absolute weight gain of a 9.0-12.9-month-old female Holstein calf was 71.4 kg, the average daily weight gain was 610 g, the relative weight gain was 30.6 %, the growth factor was 1.4 times, compensation for 1 kg weight gainer – 5.4 energy feed units, and for the Flekvi breed – 62.6 kg, 535 g, 27 %,1.3 times, and 6.2 energy feed units, respectively.
According to the data of linear growth, the height of the body parts of the 9.0-12.9 -month-old female Holstein breed increased by 3.0-3.7, width by 3.0-3.3, length by 0.9-4.3, chest depth – 3.1, breast width – 3.6, forearm width – 0.7 cm, and Flekvi – 2.3-3.2, 0.7-2.6, 0.7-6.1, 1.7, 5.5 and 1.4 cm, respectively.
Body composition indices also prove that the body structure of the 12.9-month-old female Holstein and Flekvi breeds has also developed proportionally.
Therefore, we suggest to graze 6-month-old calves and older animals of different gender and age groups in the Armavir region of RA in winter pastures.
