Em se tratando de sistema circulatório, encontramos um grande número de variações que são observadas e documentadas com frequência na literatura, dentre estas variações estão as das veias testiculares. A veia testicular apresenta grande variabilidade quanto ao número, trajeto e locais de drenagem, sendo que algumas destas variações podem levar a esterilidade masculina. A proposta do nosso estudo é descrever uma variação encontrada na veia testicular direita, em cadáver formolizado de adulto. Durante uma dissecação rotineira no Laboratório de Anatomia da Faculdade de Medicina da FAP-Araripina, localizada no Estado de Pernambuco, encontramos em um cadáver masculino de aproximadamente 45 anos uma variação na veia testicular direita. Esta se apresentava única e próximo a sua terminação se bifurcava em um ramo superior e um inferior. A partir da bifurcação até a chegada na veia cava inferior, o ramo superior apresentou-se com um comprimento de 96mm e o inferior com 74mm. A distância entre os dois no ponto de drenagem na veia cava foi de 24mm e a distância do ponto de entrada do ramo superior na veia cava inferior para a veia renal foi de 14mm. Diante do exposto, variações anatômicas são muito importantes na prática médica, principalmente em se tratando do sistema vascular.

A infecção por toxoplasmose durante a gravidez e seu desfecho potencialmente trágico para o feto e recém-nascido continuam a ocorrer no Brasil, apesar de poderem ser prevenidas. A toxoplasmose gestacional no estado do Amazonas emerge como um desafio complexo, intrinsecamente ligado às características singulares dessa região. O Amazonas, com sua vasta biodiversidade e ecossistemas únicos, apresenta um cenário propício para a interação entre seres humanos, animais e o agente etiológico. Nesse sentido, compreender os fatores de risco e evidenciar as populações mais vulneráveis é crucial para intervenções mais eficientes. O objetivo desse trabalho foi analisar a prevalência e o perfil epidemiológico dos casos de toxoplasmose gestacional no estado do Amazonas no período de 2019 a 2022. Trata-se de um estudo descritivo, quantitativo e retrospectivo, que realizou a análise dos casos de toxoplasmose em gestantes no estado do Amazonas, no período entre 2019 e 2022. Todos os dados foram extraídos da base de dados Sistema de Informações de Agravos de Notificação (SINAN), disponíveis na plataforma do Departamento de Informática do Sistema Único de Saúde (DATASUS). A frequência da toxoplasmose gestacional no Amazonas apresentou tendência crescente. Segundo o SINAN, o Brasil registrou, no período de 2019 a 2022, 435 casos. Os dados sociodemográficos demonstraram que no Amazonas, os casos de toxoplasmose gestacional apresentaram um aumento expressivo nos últimos cinco anos, com a infecção predominando em mulheres pardas com idade entre 20 a 39 anos. Além disso, as infecções foram mais prevalentes no segundo trimestre de gravidez. Os nossos resultados sugerem que fatores socioeconômicos, vulnerabilidade social e acesso limitado à informação, podem contribuir para o risco de desenvolver toxoplasmose gestacional.

Published: January 2024

Esensi dari kurikulum merdeka adalah untuk meningkatkan kualitas pendidikan di Indonesia dan menghasilkan generasi masa depan yang kuat secara intelektualitas, karakter dan memiliki semangat sebagai pembelajar sepanjang hayat. Penerapan kurikulum merdeka pada jenjang pendidikan dasar tentu tidak serta merta dapat diterima dengan baik oleh setiap lembaga pendidikan, hal ini dikarenakan pemahaman terhadap konsep penerapan kulikurum merdeka kurang utuh, sehingga tidak jarang terjadi kebingungan dalam penerapannya. Kegiatan workshop ini dilaksanakan karena kurangnya pemahaman terhadap kurikulum merdeka baik untuk sekolah maupun dalam pembelajaran. Pendidik sering mengalami kesulitan dalam pelaksanaan pembelajaran, terutama pada aplikasi metode pembelajaran yang kreatif dan inovatif. Metode yang digunakan dala kegiatan ini adalah metode FGD (Forum group Discussion), dimana pemateri menggali informasi terlebih dahulu kepada para peserta, sehungga materi yang disajikan dapat menjawab permasalahan yang dirasakan oleh peserta, selanjutnya pemateri menyaikan materi, dan diakhiri dengan diskusi antara peserta dengan narasumber (pemateri) dan penugasan. Setelah kegiatan ini diharapkan adanya perubahan terkait dengan mindset para pendidik di SDIT Riyadul Mubtadiin terhadap implementasi kurikulum merdeka. Dalam mengembangkan lembaga pendidik/ pihak yang berwenang dapat menyesuaikan dengan konsep yang terkandung dalam kurikulum merdeka. Selain itu, yang lebih penting lagi adalah pendidik dapat melaksanakan kegiatan pembelajaran sesuai dengan konsep dan prinsip yang dibangun dalam kurikulum merdeka.

Published: January 2024

This study investigates the performance of an ethylene glycol/water (EG/Water) fluid at a 40:60 volume ratio, a commonly used base fluid in heating and cooling systems. The evaluation focuses on analyzing heat transfer coefficients and pressure drops. The research adopts an experimental approach, utilizing a test section made of pure copper with an inner diameter of 16 mm, an outer diameter of 19 mm, and a length of 1500 mm. The volume ratio of EG/Water at 40:60 is an input parameter, along with varying fluid flow rates controlled by a valve, ranging from 2 to 18 liters per minute. Two tubular heaters with a combined capacity of 2000 W are attached to the copper pipe, regulated by a 3000 W voltage regulator. Electric current is measured with ammeters. The experimental results reveal that the heat transfer coefficient of the EG/Water fluid increases as the fluid flow rate rises. The highest heat transfer coefficient is achieved at 18 L/min, while the lowest is observed at 4 L/min. Pressure drop increases with higher flow rates, but this does not significantly affect the friction factor, as it undergoes a noticeable decrease while the Reynolds number increases.

Published: January 2024

Transformer oil (TO) serves as a cooling fluid and insulation medium in transformers. One cause of the decline in the quality of TO is flashover, leading to overheating of the oil inside the transformer. Flashovers, which are sudden electrical discharges in transformers, can lead to the generation of gases within the insulating oil. Understanding the changes in gas content is crucial for assessing the health and condition of the transformer. Gas analysis was conducted using the Total Dissolved Combustible Gas (TDCG), Doernenburg and Roger’s ratio method, focusing on gases extracted from both transformer oil and the gas space. The results provide valuable insights into the effects of flashovers on gas production and aid in the diagnosis of potential issues within the transformer. The TDCG values for all cycles are higher than those for the original oil. This is due to the flashover simulation using BDV testing, causing a change in the gas values contained in the TO. Based on the TDCG results the transformer is in condition I. If this occurs during actual transformer operation, the transformer can continue normal operation with certain considerations, namely, exercising caution, analyzing for individual gases, and determining load dependence. Both analyses using the Doernenburg and Roger's ratio method indicate "No Fault." Therefore, if flashover simulation is conducted using the BDV test, it will cause a change in gas content in the oil but will not lead to anything fatal.
An Optimizing the Control of DC Motors in CNC Machines by Enhancing the Parameters of the Proportional-Integral-Derivative (PID) system
Authors: Teguh Setyawan Reinaldi
Published: January 2024

In this article, the PID controller design for a DC motor used in a CNC machine is discussed, with a focus on rotor angular speed regulation. A DC electric motor is an electrical machine that utilizes DC current to generate mechanical torque, which is essential in CNC applications. The PID controller, or Proportional-Integral-Derivative, is often employed to regulate the speed of DC motors based on desired parameters. This approach not only addresses the technical aspects of PID controller design but also integrates action research methods to enhance understanding and practical implementation in the context of using DC motors in CNC machines. In this study, the design of a DC motor controller with a PID closed-loop block aims to reduce the rise time value in the transfer function design. By applying the PID controller to a rotor speed of 13 rad/s, experimental results show a settling time of approximately 0.68 seconds and an overshoot of 3.02%. The lowest rise time achieved is around 136.893 milliseconds.

According to the literature, intestinal lymphoma is currently the most common tumor disease of the digestive canal in cats and is characterized by a severe course and poor response to chemotherapy. Because this tumor shares clinical and ultrasound characteristics with inflammatory bowel disease, diagnosis is challenging and requires a number of complex procedures that often cannot be performed without sedating the animal. In connection with the above, the purpose of this work was to identify ultrasonographic prerequisites for intestinal lymphoma in cats and substantiate the stages of development of intestinal lymphoma in cats. The objects of the research were cats of various breeds (34 animals in total), various sex and age groups. All animals underwent a clinical examination using standard methods, as well as ultrasonographic examination of the abdominal cavity. Ultrasound studies revealed such changes as thickening of the intestinal wall, a change in the ratio of layers with partial or complete loss of differentiation of the intestinal layers, a decrease or increase in the echogenicity of the layers of the intestinal wall, heterogeneity of the echostructure, deformation of the lumen with the presence of heterogeneous anechoic contents, impaired peristalsis, a local increase in the echogenicity of the surrounding fatty tissue. tissue, pronounced enlargement of lymph nodes with changes in their echostructure and echogenicity, the presence of free fluid in the abdominal cavity. The diagnosis was confirmed using cytological and histological studies.

The work is devoted to studying the peculiarities of changes in the biochemical parameters of the blood of cows with fascioliasis during treatment with the drug niacid-plus. According to the results of the experimental material obtained by the authors, the negative impact of the causative agent of fascioliasis on the main biochemical parameters of cows is expressed in a significant decrease in protein synthesizing activity and an increase in the activity of AST and ALT transaminases. The complex antiparasitic drug niacid-plus, containing closantel and abamectin, at a dose of 1 ml per 50 kg of body weight, completely frees cows from fascioli and this leads to the normalization of the animals' metabolism. In the blood of cows receiving the drug, there is a decrease in the level of transaminases and an increase in the content of total protein. An increase in the thioldisulfide ratio and a decrease in the content of malondialdehyde in the blood was also shown, which indicates an increase in the nonspecific resistance of the cow’s body.

Histamine is a substance dangerous to human health, which may be present in food products in case of violations of storage or production conditions, which may depend both on the content of the initial component (amino acid histidine) in fish, and on the content of decarboxylating microorganisms and the availability of optimal conditions for their reproduction and vital activity. Based on the high danger of histamine for human health, its content is regulated by regulatory documents in many countries of the world, including the Russian Federation. Therefore, it is necessary to carry out strict control of fish and fish products for histamine content. To control the histamine content, modern techniques based on accurate and sensitive analysis methods are needed, such as the method of high-performance liquid chromatography with mass spectrometric detection (HPLC MS/MS). The article is devoted to the creation of HPLC MS/MS methods for the determination of histamine in fish and fish products. The obtained data for chromatographic histamine isolation and its mass spectrometric determination, as well as metrological characteristics of the technique are presented. The expansion of monitoring studies of histamine content in fish and fish products will allow monitoring not only the safety, but also the freshness of products. The article is devoted to the development of HPLC MS/MS methods for the determination of histamine in fish and fish products. The data for chromatographic histamine isolation and its mass spectrometric determination were obtained, the sample preparation algorithm was determined, as well as the metrological characteristics of the technique.

Laboratory mice are one of the most popular objects for biological studies. To obtain reliable data in experiments using laboratory mice, standardized conditions are necessary, which also include normal state of animal health. When a significant number of animals are kept in a conventional vivarium, pathogens accumulate in the population, which significantly impairs the animals' health and complicates the reproduction of the population. In addition, a significant pathogenic load can pose a serious obstacle to conducting experiments and receiving accurate data. One of the ways to eliminate the pathogenic load is the total destruction of the infected population, disinfection of the vivarium and population recovery by purchase of animals. If valuable genetically modified animals and/or unique inbred strains are present in the vivarium collection the problem cannot be solved by replacing the population. In this situation, it is necessary to use reliable methods of rederivation that guarantee removal of pathogens. In this paper, we describe approaches for the rederivation of genetically modified animals collection in the mouse facility of the IGB RAS. Described technique allows to reliably purify a population of valuable animals from a number of pathogens such as Mycoplasma pulmonis, Streptococcus agalactiae, Helicobacter pylori spp, Mouse minute virus, Mouse parvovirus vp2.

The results of assessing the immunogenicity of the Ausvak vaccine for the specific prevention of sows against Aujeszky's disease based on the results of the formation of colostral immunity in piglets are presented. This vaccination regimen has been established to be safe and highly effective for both sows and their offspring. The effectiveness of vaccination was confirmed by ELISA testing of null and post-vaccination animal sera to detect specific gE and gB antibodies and by control infection of piglets with the virulent Aujeszky's disease virus.

This article discusses methods of prevention and control of Salmonella abortion in small cattle (sheep and goats), salmonellosis is a widespread infectious disease of all animal, avian and human species caused by bacteria of the genus Salmonella of the family Enterobacteriaceae. The genus Salmonella Abortusovis is adopted in sheep whose main symptom is abortion. It is a gramnegative bacterium which is prevalent in Western Asia, Europe and the Mediterranean area. Sheep can shed the bacteria through colostrum, milk or feces and can become infected through the oral, conjunctival or respiratory route. The methods studied include health and hygiene prevention, metaphylaxis and vaccination. The results of the study show that all these methods studied help to relieve breeders but they are not completely efficient and effective. And on the other hand, the use of bacteriophages is the most promising method that can be used as an alternative for the control of Salmonella Abortusovis due to its specificity, safety and effectiveness.

Most body-built indices allow the most complete assessment of the animals’ constitutional type and the direction of productivity. It was found that the indices of lengthiness, blockiness, pelvic, thoracic, massiveness, boniness, meatiness increased with the age of animals, and legginess, complex, overgrowth tended to decrease. For the experiment, mature cowbanes of the Simmental, Limousin and Aubrac breeds, which met a set of traits not lower than the breed standard, were selected. The breeding stock females were artificially inseminated with semen from sires of the corresponding breeds. From the resulting offspring, 5 groups of bull-calves, 12 heads in each, were formed: I – Simmental, II – Limousin, III – Aubrac, IV – Simmental×Limousin crossbreeds, and V – Simmental×Aubrac crossbred bull-calves. At the ages of 7, 12, 15 and 18 months, basic measurements were carried out in order to study the linear growth and exterior features of different animals’ genotypes. In turn, on the basis of their results, body-built indices were also calculated. In animals of each genotype when they were weaned from their mothers at the age of 7 months, then at 12, 15 and 18 months, linear measurements were taken. A bodybuilt index assessment of the experimental animals’ groups confirmed that the crossbreeds were superior to the animals of the Simmental, Limousin and Aubrac breeds in terms of massiveness and meatiness indices in all age periods. They were characterized by relatively high body breadth and blockiness index, better expression of meat shapes. It was noted that in terms of the legginess, body breadth, thoracic and overgrowth indices in one-and-a-half-year-old animals, no significant differences were found between individual animals of the presented genotypes. The massiveness index at 1,5 months of age was the highest and the same in crossbred animals. According to the value of this indicator, their Limousin and Aubrac peers were inferior to them by 18 % (P>5,0), and the Simmental – by 0,95 % (P>10,6). This was confirmed by the greater live weight of crossbred animals.
