Published: July 2024

El presente trabajo se propone elaborar un caso de estudio acerca de la gestión del cambio tecnológico vinculada a los sistemas de información del Laboratorio de Hemoderivados (LH) de la Universidad Nacional de Córdoba (UNC).
El caso será utilizado por estudiantes de las Carreras de Contador Público (CP) y Licenciatura en Administración (LA) de la FCE-UNC en dos asignaturas: Tecnologías de Información 1 (CP y LA) y en Diseño de Organizaciones (LA). Ambas asignaturas se ubican en el ciclo profesional de los planes de estudio de las respectivas carreras y comparten el enfoque socio tecnológico y contingente del diseño y gestión de organizaciones (Laudon & Laudon, 2016).
El propósito del caso es caracterizar la gestión de los cambios organizacionales que emergen en un cambio tecnológico, específicamente cuando una organización pone en cuestión su sistema informático y decide analizar soluciones alternativas (Tabares Quirós et al, 2021). Para ello, se describe el recorrido reflexivo y metodológico que la organización fue transitando a lo largo del proceso de cambio, integrando los aspectos del sistema social, de la estructura organizacional y del manejo de la información, así como de la toma de decisiones.

Published: July 2024

Access to musical training depends on various factors, such as socioeconomic status and musical background of families, and the child's interest in learning music (related to their openness to experience). In the present study, we show an additional source of selection bias that has gone unnoticed: the relative age of children within the same cohort. At early ages, children at different stages of cognitive and physical development are placed in the same group, in part because of the relative age difference (up to nearly 12 months). The consequences of this grouping are known as the relative age effect, ranging from academic outcomes, self-esteem, and selection of extracurricular activities. In youth sports, there has been observed an overrepresentation of athletes born in the first and second birth quarters compared to those born later. This study shows a similar unbalance across Spanish music conservatory courses in two samples: a Primary Sample of participants assessed by our research group (N = 322) and a Secondary Sample comprised by the complete census of six conservatories in Spain (N = 2182). In our sample, the relative age of the children and adolescents was an independent predictor of the other selection bias factors evaluated. Moreover, the relative age effect was stable across conservatory courses, pointing to an enrolment bias and the impact of a lack of adjustment in the conservatory entrance exam. Future research will shed light on the origins of the relative age effect in musical training, its extension, and how it can be mitigated.

Published: July 2024

The significance of increased domain nucleation sites from smaller grain size (GS) of barium titanate (BT) ceramics on piezoelectric properties was analyzed for different types of poling, including conventional DC poling, modified DC poling, and AC plus DC poling, conducted at different poling temperatures. The AC plus DC poling conducted at 1.5 °C above the Curie temperature (T
C) showed the highest piezoelectric constant (d
33) of 528 pC/N, with an average domain size of 100 nm observed after poling. The d
33 improvement was attributed to smaller domain size formation from field-induced phase transitions and homogenous distribution of point defects achieved by the AC field. Comparative analysis with larger grain BT ceramics under AC plus DC poling suggests that defects and volume fraction of grain boundaries in BT ceramics could have an effect on domain sizes.
Energetics and electronic structure of graphene nanoscrolls
Authors: Gao Yanlin , Maruyama Mina , Okada Susumu
Published: July 2024

Geometric structures and electronic properties of graphene nanoscrolls have been investigated using the density functional theory. A graphene nanoribbon with a width of 21.37 nm, corresponding to a zigzag ribbon with 100 zigzag C chains, prefers scrolled structures until the innermost shell radius of 0.6 nm, because of the competition between the energy gain by the inter-shell van der Waals interaction and the energy cost by the structural strain derived from curvature. The most preferable innermost shell radiuses are 1.3–1.5 nm for the ribbon studied here. The electronic structure of graphene nanoscrolls shows strong position dependence that is sensitive to the shape of nanoscrolls owing to the electrostatic potential modulation by their multi-shell structures.

Published: July 2024

Ruthenium (Ru) nanofilms (<3 nm) were prepared using tricarbonyl(trimethylenemethane)ruthenium, Ru(TMM)(CO)3 at 230 °C. We show that the surface morphology and electrical conductance of Ru nanofilms are substantially different on H:Si(100) and SiO2/Si(100) substrates. Two-dimensional (2D) Ru nanofilms (∼1 nm) were formed on H:Si(100), while thick (∼3 nm) granular Ru films were formed on SiO2 substrate under the same growth conditions, as confirmed by cross-sectional transmission electron microscopy and X-ray photoelectron spectroscopy. Using scanning probe microscopy, the metallic conductance of Ru grains on H:Si(100) substrates was recognized. On ultrathin (1 nm) SiO2/Si(100) substrates, the spatial separation of Ru grains facilitates the single electron tunneling (SET) phenomenon in the double barrier tunnel junction structure. The results emphasized the difference in carrier transport in Ru nanofilms on Si and SiO2 substrates.

Gizi kurang merupakan keadaan kurang gizi tingkat berat yang disebabkan oleh rendahnya konsumsi energi protein dari makanan sehari-hari dan terjadi dalam waktu cukup lama (Sodikin, 2013). Anak sekolah merupakan salah satu populasi yang paling rentan dalam hal gizi. Kekurangan dan kelebihan gizi pada anak akan berdampak negatif terhadap potensi pertumbuhan ekonomi negara. Anak yang tidak mendapatkan gizi yang cukup akan tertinggal dalam perkembangan fisik, mental, dan intelektualnya. Kurangnya asupan makanan dan tingginya penyakit infeksi merupakan dua penyebab langsung gizi buruk yang dipengaruhi oleh banyak faktor dan cukup kompleks (Rahmy et al., 2020). Pembuatan pempek identik dengan bahan utama ikan. Ikan yang biasanya digunakan adalah Ikan gabus yang memiliki kandungan protein 20 gr, lemak 1,5 gr, karbohidrat 0,2 gr, mineral 1,3 gr,dan air 77 gr. Agar kandungan gizi didalam pempek lebih banyak dapat juga ditambahkan dengan bahan lain, Penambahan tepung labu kuning yang tinggi antioksidan serta penambahan jamur tiram putih yang mempunyai kandungan protein tinggi dan asam amino esensial yang baik bagi anak (Aryadi, 2020).

Pest infestation is a major challenge in production of golden melon, this study evaluated the performance of Beauvaria bassiana, a non-residual bio-pesticide, for effectiveness against insect pests of golden melon. The field experiment was carried out in 2022 to establish the effect of B. bassiana sprayed at different growth stages on the abundance of insect pests, damage, agronomic characteristics and fruit quality of golden melon. The results showed Aulacophora spp., Aphis gossypii, Epilachna chrysomelina, Bemisia tabaci Coridius viduatus and Zonocerus variegatus as the insect pests attacking golden melon in the study area. However, the population densities of Aulacophora spp. and E. chrysomelina were significantly lower in golden melon sprayed with B. bassiana at all compared to other spray treatments and the control. Percentage leaf damage and yield loss (20.81% and 327.70 g) in golden melon sprayed with B. bassiana at all stages were similar to lambda-cyhalothrin-sprayed plot (13.68 % and 318. 70 g). Also, highest percent leaf damage and yield losses (81.54 % and 1395.70 %) were obtained in the control plots relative to other spray treatments. Number of leaves and percentage increase in vine length were significantly higher in the golden melon sprayed with B. bassiana at all stages. There was 215.80 % increase in yield of golden melon sprayed with B. bassiana at all stages over the control in the study. Also, the nutritional composition of the fruits from the untreated plots was similar to that of the treated plots

Published: July 2024

Mealworm (Tenebrio molitor) insect meal has been adjudged a protein source for human and livestock consumption. Substrates of agricultural by-product are been used to rear this insect, and it is of importance to investigate the implication of substrate on the content of the end product. This study was conducted to assess the nutrient composition of T. molitor cultured on three grain by-products as growth substrate media [Rice Bran (RB), Corn Bran (CB) and Wheat Bran (WB)] for 90 days. Harvested larvae were sundried, ground into powder and analysed for proximate composition as well as mineral content and the data statistical analysed. Protein was highest in CB reared larvae 51.33% with least in RB reared larvae 46.74%. Fat was high in all sampled substrate reared mealworm. Ash content in CB and WB was significantly different (P<0.05) from RB reared larvae. Macro mineral Mg and Na are not significantly different, while micro mineral profile showed significant variations (P<0.05). The nutritional composition of T. molitor in this study positioned it as a potential substitute for incorporation into fish feed formulation as animal protein source.
Le alternative prese sul serio. Filosofia sociale, metamorfosi e mutualismo produttivo
Authors: Mazzone Leonard
Published: July 2024

The article claims for social philosophy a public function similar to that claimed in the sociological field by Michael Burawoy. Canetti’s concept of metamorphosis is the best candidate to translate the immanent and heretical normativity of social philosophy: once summarized the core features of this concept and its link with social philosophy, I will focus on a particular case of real utopias: namely, the recovered companies by workers. After presenting the main characteristics of the cooperative recovery of companies in crisis or at risk of delocalization, the contribution will resume the different processes of genesis of recovered enterprises and, at the same time, the main indicators that allow us to interpret them as garrisons of labour democratization and, in some cases, as real actors in processes of social metamorphosis.
Relazioni pubbliche: pars communicans della «sociologia pubblica»?
Authors: Bennato Davide , Strizzolo Nicola
Published: July 2024

The contribution seeks to position public relations (PR) as a communicative component of public sociology (PS), tracing the evolution of PR from its inception to the modern-day constructs that form its theoretical foundation and practical activities. It argues that concepts such as stakeholder, relationship, and reputation are not merely central to PR but also intricately intertwined and utilized within the realm of sociological inquiry. The paper underscores the societal impact of PR, especially emphasizing corporate social responsibility (CSR) and social campaigns. These efforts aim to propagate specific issues, cultivate a collective awareness, and ultimately provoke transformation in social attitudes and behaviors. A notable tension exists within PR between empirical practices and scientific precision, drawing attention to the need for interdisciplinary strategies and mid-range theories to bridge this gap. PR, while not exclusively, is primarily situated within the social sciences and, more specifically, within the Sociology of Cultural Processes as an academic discipline. This article calls for a deeper integration between PR and PS, advocating for the use of shared concepts, categories, methods, and tools. Additionally, PR targets the identification of distinct publics and the initiation of active, participatory dialogue with them. Although the predominant literature and major journals in PR are American, the article acknowledges that PR’s application on local grounds is where the synthesis of local and global takes place, demonstrating the field’s wide-reaching relevance and adaptability.
All’ombra dell’istituzione totale. La «sociologia pubblica» alla prova del penitenziario
Authors: Borghini Andrea
Published: July 2024

The contribution aims to reflect on the emancipatory role that sociology can play, in its public dimension, when confronted with a total institution, such as the penitentiary. The historical-critical assumptions from which the reflection moves can be traced, on the one hand, to those values of inclusion and social justice to which public sociology, in the ‘version’ that Burawoy (re)launched in 2004, looks to as inalienable ethical principles. And which, notoriously, due to the type of inmate population in penal institutions (Italian and otherwise) and the history of the penitentiary itself, are often disregarded and ignored. On the other hand, it seems more interesting than ever to test the liberating capacity of sociology in a ‘public’ institution such as the prison, in comparison with a ‘public’ with peculiar characteristics, which only partially reflects that notion of organic public that has become increasingly central in Burawoy’s conception. This ‘social experiment’ will be conducted from a particularly interesting case study, namely the project of university prison centres, which constitute a virtuous encounter between university culture and the prison world. Specifically, the group under investigation will be inmates enrolled in university courses. Through this case study, it will be possible to verify the limits and possibilities of a sociological style, which turns out to be sociology in its public version, which represents, in an era of strong social inequalities and urgent global issues, a valuable tool to give voice and centrality to sociology, to its critical demands and, through of it, try to listen to the ‘cry of pain’ coming from a growing part of the men and women of our world.
«I was in exile before leaving the country». Tunisia and the Feminist Continuities of Activism
Authors: Stragapede Maria Nicola
Published: July 2024

What happened to the women who participated in the 2010-2011 Tunisian revolutions and subsequently left the country? While scholarly work has extensively delved into the engagement of the young generations who participated in these transformative times, there has been a limited attention to the experiences of women who subsequently underwent journeys of exile. This article seeks to empirically fill this gap by looking at the political trajectories of six women activists, spanning from their participations in the 2010-2011 Tunisian uprisings to their experiences in exile. Drawing on ethnographic research and life history interviews conducted between 2021 and 2023, this article shows the transformations in these activists’ political trajectories before they left the country. Furthermore, it outlines how, even in exile, queer and feminist activism has provided these women a space of engagement through a “multiple identifications” of their political attitudes and interests. Adopting a social movement approach focused on the continuities of engagement, this article contributes to two fields of the literature that have been traditionally studied in isolation: the literature on gendered borders and the literature on gendered transformations throughout revolutionary times. Finally, the article emphasises the importance of studying the transformations of meanings of engagement while analysing political continuities.
Liminalities: Social Vulnerabilities Between Participatory Processes and Digital Space in the Neoliberal Era
Authors: Antonucci Maria Cristina , Sorice Michele , Volterrani Andrea
Published: July 2024

This article explores the development directions of liminal spaces and cities as a whole within the broader framework of neoliberalism in the Italian metropolitan context. First, neoliberalism was defined and considered in the context of liminal spaces and urban development, according to the international literature perspective. Then, with specific reference to the Italian case, through semi-structured interviews, it was found that liminal spaces, despite facing marginalisation, translocalisation and defamiliarisation, acted as antagonists and nuclei of resistance to the encroaching framework of neoliberalism. The article also explores the role of digital ecosystems as tools for empowerment; it also emphasizes the role of liminal spaces in fostering communitarianism while resisting the change experienced and brought about by the surrounding urban spaces.

The purpose of this study was to determine the perception of class X students at SMAN 1 Sungai Tarab towards Geospatial Technology Applications. Geospatial technology is a technology that measures, analyzes, and visualizes objects or events on earth. This research uses a qualitative descriptive approach. The selection of subjects in this study used a total random sampling method consisting of 255 class X students. The research data were collected using a semi-open questionnaire method with a google form consisting of 25 questions given the answer options yes, no, and others. The results showed that there were 68.41% of students answered yes with the Good category, on the indicator of using geospatial technology applications as learning media. There were 64.61% of students answered yes with the Good category, on the indicator of the use of geospatial technology as learning material. And there are 70.44% of students answered yes with the Good category, on the indicator of the use of geospatial applications in everyday life. From the perception of students, there are still many students who do not know and use geospatial technology applications. Based on observations made at SMAN 1 Sungai Tarab, it appears that geography teachers have not utilized this geospatial technology application-based learning media.

Published: July 2024

Antinuclear antibodies (ANA) are significant biomarkers that are used to detect and classify autoimmune connective tissue disorders more efficiently. This paper provides a thorough overview of all the ANA profiling procedures, their testing advancements, clinical significance, and future directions. This study aimed to analyze the ANA profiles along with the prevalence of specific antibodies in patients presumed to have been diagnosed with autoimmune disorders in an Eastern Indian tertiary care hospital. The results were correlated with demographic data to conclude. ANA profiles of 48 patients from Peerless Hospitex Hospital, Kolkata were evaluated between January 24 to June 15, 2024. Out of them, 13 patients (27%) had positive ANA profiles. The most prevalent autoantibodies detected were SS-A and SS-B, which occurred in 7 patients (53.85%), followed by PM-Scl in 4 patients (30.77%). The study demonstrates how the ANA profile varies among different age groups, with the highest prevalence of 6 patients (46.15%) seen in the 60–75 age range. The clinical symptoms of diseases like autoimmune hepatitis, polymyositis, dermatomyositis, PSS (progressive systemic sclerosis), SLE (Systemic Lupus Erythematosus), and Sjogren's syndrome align with the ANA profile findings. This study offers insights into the distribution of autoantibodies targeting antigens present in ANA profiles, using clinical samples collected from a 550-bed tertiary care hospital in Eastern India. The findings underscore the need for comprehensive diagnostic approaches to autoimmune disorders.

Background: Pressure injuries rank among the top five most frequent causes of patient injury worldwide. Usually, these ulcers develop in the body's bony regions where there is a higher chance of pressure and tissue deformation. Pressure injuries are still a common and severely incapacitating ailment, even with advances in medical understanding and the development of efficient therapies and preventative measures. They result in large socioeconomic consequences since they place a heavy load on the healthcare system and the affected individuals. Objectives: To assess the occurrence rate, identify correlated risk factors, and analyze additional indicators related to pressure injuries diagnosed within the care units of King Saud Medical City throughout the study period. Methodology: A descriptive cross-sectional study was undertaken at King Saud Medical City in Riyadh during the months of August and September 2023. The study focused on patients with newly identified pre-existing pressure injury lesions. Demographic information and associated risk factors were recorded in the study's data extraction sheet after obtaining participants' consent to engage in the research. The study commenced following approval from the institutional review board of king Saud medical city research and Innovation center, Riyadh. The gathered data were analyzed using the Statistical Package for the Social Sciences (SPSS), version 26. Descriptive statistics, bivariate and multivariate logistic regression were computed to assess the statistical association, using odds ratio. Significance of statistical association was assured and tested using 95% confidence interval and P-Value of < 0.05 is considered statistically significant. Results: A total of 250 patients with pressure ulcers were identified during the study period. Most of the study participants were male, and the mean age of the participants was 59.2 years. The prevalence of pressure injuries in the hospital units included in the study was 18.8%. The sacral region was the most affected site, with 121 patients (48%) having pressure injuries in that area, while 83 patients (33%) had pressure injuries in the gluteal area. The most frequently associated comorbidities were hypertension, present in 140 patients (56%), and diabetes mellitus, present in 123 patients (49.2%). Conclusion: The prevalence of pressure ulcers was high among admitted patients at King Saud Medical City, Riyadh. Primary prevention health promotion programs should be implemented to prevent the occurrence of pressure injuries in our healthcare facilities and the community at large.

Published: July 2024

Work related stress is the adverse reaction as a result of excessive work pressure. As new diseases such as Corona virus, Ebola, Lassa fever, Monkey pox, etc evolves each day, so technology and new skills to tackle such diseases are required. In addition to clinical nursing care, the need to learn and practice how to use modern equipment in patients’ care to combat such diseases imposes more stress on the nurses. The world population is also on the increase, hence the need for healthcare services is also increasing. Contrarily, there are (six) 6 million global nurses’ shortage presently. The recent Covid 19 pandemic is also putting on more stress on the nursing workforce forcing many nurses to leave their job as a result of work-related stress. The study aimed at investigating key interventions that will reduce work relate and enhances nurses work performance.

Immune-related adverse events (irAEs) have become increasingly prevalent with immune checkpoint inhibitor (ICI) cancer treatment. We present a 79-year-old man with metastatic renal cell carcinoma who developed shortness of breath and hypercapnic respiratory insufficiency after his first cycle of nivolumab and ipilimumab. Laboratory data showed elevated creatinine kinase, troponins, and transaminases. Computed tomography of the chest demonstrated bilateral lower lobe atelectasis. Heart catheterization and endomyocardial biopsy were unremarkable. Electromyogram (EMG) and nerve conduction studies (NCS) of the limb muscles revealed mild diffuse myopathy, normal sensory nerve conductions, and low-amplitude motor responses. Subsequent diaphragmatic EMG and NCS demonstrated severe myopathy. ICI-mediated myopathy predominantly affecting diaphragmatic muscles was diagnosed. Treatment included intravenous methylprednisolone, infliximab, abatacept, rituximab, and plasmapheresis. He underwent tracheostomy placement on hospital day 11 due to minimal improvement. He was discharged to a long-term acute care hospital, but unfortunately, he died less than 1 month later due to recurrent infections. irAEs can affect any organ system, but diaphragmatic dysfunction is uncommon. Use of diaphragmatic EMG, NCS, ultrasound study, or biopsy can support the diagnosis. Treatment includes systemic steroids, plasmapheresis, immunosuppressive medications, respiratory support, and cessation of causative medications. ICI-related diaphragmatic dysfunction should be suspected in those patients at risk with hypoxia, hypercapnia, or prolonged invasive or noninvasive ventilation without a distinct etiology. This case report exemplifies the importance of multidisciplinary workup and management of respiratory symptoms and insufficiency to identify and ameliorate irAEs. Diaphragmatic involvement can be associated with significant morbidity and mortality despite early aggressive multimodal therapy.

Asbestos was largely used in Brazil. It is a mineral that induces pleural and pulmonary fibrosis, and it is a potent carcinogen. Our objective was to develop recommendations for the performance of adequate imaging tests for screening asbestos-related diseases. We searched peer-reviewed publications, national and international technical documents, and specialists' opinions on the theme. Based on that, the major recommendations are: Individuals exposed to asbestos at the workplace for = 1 year or those with a history of environmental exposure for at least 5 years, all of those with a latency period > 20 years from the date of initial exposure, should initially undego HRCT of the chest for investigation. Individuals with pleural disease and/or asbestosis should be considered for regular lung cancer monitoring. Risk calculators should be adopted for lung cancer screening, with a risk estimate of 1.5%.

Identifying food and calculating calories are key components of encouraging good eating habits and controlling dietary intake. These days, it's easier to create smart systems that can recognize food items from images or videos and calculate their calorie content using artificial intelligence, computer vision, and machine learning. This study gives an overview of the latest methods and tools for calorie counting and food identification. It looks at the challenges of accurately identifying different foods, including complex dishes and foods from various cuisines, and addresses the variables taken into account when determining the calorie content of food items, including ingredient composition, portion size, and nutritional makeup. To enhance user experience and enable comprehensive calorie tracking, it explores real-time processing capabilities, user-friendly interfaces, and integration with other health and fitness platforms. Additionally, it provides a list of potential recipes. The interface developed in the proposed system is currently trained to identify and provide the calories of 100 food items, including basic food items, fruits, vegetables, and processed foods. The research work uses a real-time dataset for training and employs software such as YOLOv8, and TensorFlow for practical implementation.

The electromyography (EMG) signal measures the electrical activity of muscles and is often described as a function of amplitude, frequency, and phase over time. These signals are commonly employed in both clinical and biomedical applications. They are used to identify neuromuscular disorders and in other activities such as controlling robots and computers. This proposed study utilizes the CNN to analyse the hand gestures and extract valuable information from these gestures. Consecutive training and testing using images were conducted to evaluate the CNN's performance. The findings demonstrate the effectiveness of the proposed methodology in discerning significant features from complex movements.

Abstract Background There was no scientific evidence about the initial treatment of hypertonic saline solution (HSS) in acutely decompensated heart failure (ADHF). Objectives This study assessed the impact of using HSS along with a loop diuretic (LD) as the first diuretic treatment for ADHF, focusing on renal function, electrolyte levels, and clinical outcomes. Methods In this retrospective case-control study, 171 adult patients (93 females/78 males) with ADHF were included between January 1, 2022, and December 31, 2022. Patients were allocated into two groups: upfront combo HSS+LD and standardized LD. The primary endpoint was worsening renal function (WRF). Hospitalization for HF and all-cause mortality were evaluated during 6 months of follow-up. The significance level adopted in the statistical analysis was 5%. Results The groups exhibited similarities in baseline characteristics.A significantly higher diuresis on the 1st day (3975 [3000-5150] vs. 2583 [2000-3250], p=0.001) and natriuresis on the 2nd hour (116.00 [82.75-126.00] vs. 68.50 [54.00-89.75], p=0.001) in the initial upfront combo HSS+LD were found in comparison with the standardized LD.When compared to the standardized LD, the utilization of HSS led to an increase in serum Na+ (137.00 [131.75-140.00] vs. 140.00 [136.00-142.25], p=0.001 for upfront combo HSS, 139.00 [137.00-141.00] vs. 139.00 [136.00-140.00], p=.0470 for standardized LD), while chloride (99.00 [94.00-103.25] vs. 99.00[96.00-103.00], p=0.295), GFR (48.50 [29.75-72.50 vs. 50.00 [35.50-63.50, p=0.616), and creatinine (1.20 [0.90-1.70] vs. 1.20 [1.00-1.50], p=0.218) remained stable in the upfront combo HSS group when compared to standardized LD group (Cl-: 102.00 [99.00-106.00] vs. 98.00 [95.00-103.00], p=0.001, eGFR: 56.00 [41.00-71.00] vs. 55.00 [35.00-71.00], p=0.050, creatinine:1.10 [0.90-1.40] vs. 1.20 [0.90-1.70], p=0.009). Worsening renal function (16.1% vs 35.5%, p=0.007), and length of stay in the hospital (4 days [3-7] vs. 5 days [4-7], p=0.004) were lower in the upfront combo HSS+LD in comparison with the standardized LD. In-hospital mortality, hospitalization for HF, and all-cause mortality were similar between the two groups. Conclusion HSS as an initial therapy, when combined with LD, may provide a safe and effective diuresis without impairing renal function in ADHF. Therefore, HSS may lead to a shorter length of stay in the hospital for these patients.

Published: July 2024

The aim of the study is to investigate the relationship between bacterial contamination of bull semen and the biological value of spermatozoa, as well as reproductive performance. The object of the study was Holstein bulls (n = 17). The material for the study was frozen-thawed semen of bulls in the amount of 61 samples. Microbiological studies of sperm doses were carried out using standard nutrient media in accordance with GOST 32222-2013. The total number of microorganisms was calculated by the number of grown colony-forming units (CFU/ml) in 1 cm3, with subsequent determination of their morphological pro-perties. Sperm motility and morphology were determined using the Argus CASA program. The state of DNA in spermatozoa was studied by the acridine orange test (AO test) using a fluorescence microscope. The study revealed a high positive correlation (r = +0.940**) between the number of microorganisms in sperm and pathology in individual sperm segments. Analysis of variance confirmed a statistically significant effect of the number of microorganisms on sperm morphology F = 123.2 (p=0.000). The correlation relationship between the fragmentation index and the content of microorganisms has a high value (r = +0.965**). Sperm motility negatively correlates (r = –0.768**) with the number of microorganisms (CFU/ml). In the presence of Mycoplasma spp in the samples, the number of cows with fruitful insemination was 35.5 % due to reduced motility, morphology and high fragmentation of sperm DNA (58 %). Sperm motility in samples containing Mycoplasma spp averages 24.5 %, while in samples without these microorganisms it is 48.9 %. Thus, it can be assumed that the presence of Mycoplasma spp in samples and high bacterial contamination rates lead to to lower reproductive performance in bulls.

The aim of the study is to conduct a comparative assessment of the infestation of horses with intestinal helminths in various administrative districts and to characterize the patterns of the relationship between abiotic and anthropogenic environmental factors and the rates of infestation of horses with intestinal helminths in the Gorny Altai. Based on long-term (2019–2023) ovoscopic examinations of 1.2 thousand horses from 10 districts of the region, the infestation of animals with helminths of the gastrointestinal tract was characterized. Correlation analysis was used to characterize the relationship between the level of infestation of animals with helminths, the number of parasites with abiotic and anthropogenic environmental factors in the context of farms and districts of the Gorny Altai. Horses are mostly infected with helminths in the Chemalsky District, where the prevalence of infestation is 95.8 %, and the infection intensity is 458.3 eggs per gram of feces. The lowest prevalence of helminths in animals was recorded in the Ust-Kansky District – EI 56.3 %, with IIs – 186.7 specimens. g/f. The prevalence of infestation in animals is significantly lower in areas characterized by low temperatures and precipitation, and significantly higher in warmer and more humid areas of the region. The prevalence of infestation in horses is 84.6 %, with IIs – 337.5 specimens. g/f. The most significant factors influencing the infection of animals with intestinal helminths (EI, % and IIs) in farms are the long-term average annual precipitation (r = 0.42 and 0.52) and the degree of anthropogenic pressure (r = –0.55 and –0.63), in the context of regions, long-term average annual temperatures (r = 0.55 and 0.65) and long-term average precipitation (r = 0.69 and 0.65).

The purpose of the study is to develop a calculation method for a continuous supply system for highly viscous food masses, taking into account the characteristics of the pipeline, cam pump and rheological parameters of the pumped food liquid. The paper considered a system for supplying processed cheese with rheological parameters at temperatures from 55 to 95 °C. As a result of hydraulic calculations using published data, it was found that 1) calculation of the effective dynamic viscosity μE using the Ostwald formula with the found parameter values yields results very close to the experimental data obtained from open sources; 2) the dependence of the expended power N on the pressure is linear, on the rotor speed n is parabolic, and on the dimensionless dynamic viscosity coefficient μ is power-law; 3) the dimensionless dynamic viscosity coefficient μ has different effects on the productivity Q and the power N: for large values of μ, the effect on Q decreases, while on N, on the contrary, it increases;4) with the growth of viscosity of the pumped liquid, the energy efficiency of the cam pump first improves (the hydraulic efficiency of the pump η increases, the specific energy consumption indicator E decreases), and then begins to deteriorate. The characteristic of the process pipeline (dependence of the required pressure on the flow rate of pumped processed cheese) with a given length L, local resistances, static pressure PC for three values of the internal diameter is constructed. A method is proposed that allows determining the operating parameters of the liquid food supply system at the operating point, taking into account the influence of its viscosity (using the example of pumping processed cheese).
