Published: April 2024

The purpose of the work is to optimize the technological solution for the production of molybdenum tubular fittings of heat exchangers (TСs) that work at high temperatures and external mechanical load on calculated and practical modes of electron beam welding. The results of welding largely depend on the degree of contamination of the material, and the combined calculation of EBW parameters according to a set of existing methods does not give an unambiguous solution, but allows to outline the range of their acceptable values for further experimental clarification. The proposed methods of testing welded fittings according to mechanical parameters and resistance to crack formation with simultaneous simulated application of operating temperature load (500...12000С) initiate the detection of cracks and provide information on the actual strength and plasticity of the metal of the welding zone in real conditions of operation of the fittings.

The water cycle is dependent on the ability of urban surface water to evaporate. Understanding how the at-mosphere interacts with this process is very important. It is also difficult to determine how much water is evapotran-spiration coming from urban areas due to their varying surface characteristics. A cloud cover's effect on solar radia-tion can determine how much reaches the surface of the Earth. In addition to shielding surface water, clouds can also help reduce the surface temperature gradient of the water. The paper noted that the enhanced multi-source model can be used to calculate the urban evapotranspiration of Belgrade urban area. The urban model incorporated Monteith's framework to evaluate the data from a metrological station regarding the cloud cover's data for a specific period. It then considered the various factors that affected the evaporation process, including the wind speed, air temperature, and moisture content of soil. The vegetation cover and leaf area index are also considered to calculate the overall effect of evaporation. The urban model developed by the new Penman-Monteith framework performed better than its predecessor in calculating urban evapotranspiration. The study demonstrates how urban water usage contributes to the urban heat island issue, as well as how cloud cover can also affect this phenomenon.

The esterification reaction of oleic acid with methanol practically does not occur at the temperature of most current industrial processes. If you raise the temperature, significant conversion occurs only above 200°C and after several hours. For the above reasons, all of today's industrial oleic acid esterification technologies are based on catalyzed esterification. Catalysts based on silicates are often used as catalysts in the mentioned reactions because they are cheap, easy to synthesize, insoluble in most organic solvents, and recyclable. In this work, modified mesopo-rous silica SBA-15 was used, which is suitable for a wide range of organic reactions. The effect of the amount of this catalyst on the yield of the esterification reaction was studied. It has been shown that with an increase in the amount of catalyst, the degree of conversion, i.e. the yield of methyl oleate, increases.

Spread and mitigation of antimicrobial resistance at the wildlife-urban and wildlife-livestock interfaces
Authors: Vezeau Neil , Kahn Laura
Published: April 2024

Antimicrobial resistance (AMR) is a health issue common to all One Health domains. Scientific understanding of what drives AMR and how it spreads is continually expanding. One such dimension of this expanding base of knowledge is the role wildlife populations play as reservoirs and spreaders of AMR. Indirect and direct sharing of resistant pathogens between wildlife and domestic animals occurs in a variety of ways across both the natural and built environment. Though AMR is found across much of the Earth’s biome naturally, elevated levels in wildlife are largely attributed to the use of antimicrobials in human and veterinary medicine, along with other uses of antimicrobials in human industry. On the basis of current research, wildlife species appear to be net recipients of AMR overall. However, wildlife can carry and spread AMR across individual ecosystems and to other ecosystems via water, soil, arthropod vectors, and several other routes of conveyance. In addition to creating potential health issues for wildlife animals themselves, this potentially poses risks for both companion and production animals. This is especially due to urban/suburban and rural wildlife, respectively. If health practitioners and other stakeholders are adequately aware, measures can be taken to reduce risks across each interface discussed. The companion Currents in One Health article by Vezeau and Kahn, AJVR, June 2024, addresses in further detail the many wildlife reservoirs of AMR that are currently identified, as well as directions for further research.

Copper oxide nanostructures have garnered significant attention in nanotechnology for their diverse applications. This study presents a green synthesis approach using an aqueous Aegle marmelos leaf extract-based medium to produce copper oxide (Cu4O3) nanoparticles. Optimisation was achieved through a simplified Taguchi L9 orthogonal array, investigating critical parameters such as temperature, surfactants (AOT and Tween 80), and additives (ascorbic acid and chitosan). Under optimised conditions (AOT: 0.0012 mM, ascorbic acid: 10 mM, chitosan: 1 %, temperature: 80 °C), near-spherical nanoparticles of ~200 nm were obtained. Comprehensive characterisation through UV-Vis, DLS, electron microscopy, XRD, and FTIR spectroscopy confirmed the nanoparticles’ properties, while antibacterial assays showed promising results against Escherichia coli bacteria.
Modelling and Simulation Studies on the Characteristic Behaviour of Macroalgae Derived Bio-Oil
Authors: Thirumalaikumar Ramaiah , Jaikumar Vasudevan
Published: April 2024

With the expanding need for renewable and sustainable energy resources, the demand for biomass derived bio-oil particularly microalgae or macroalgae based bio-oil is growing. In this regard, understanding the characteristics of bio-oil as a function of several influencing operational parameters is essential. In this study modelling and simulation technique based on Aspen HYSYS was applied to investigate the characteristics of macroalgae Ulva prolifera derived bio-oil from Hydrothermal Liquefaction (HTL) process as a function of the influencing parameters like temperature, kinematic viscosity, and weight percent of the bio-oil assay, cut yield behaviour, and standard liquid density. Modelling and simulation help to optimise the process parameters and design the process layout for large-scale production. According to the simulation results the cut yield of off gases, light naphtha, heavy naphtha, light distillate, heavy distillate, gas oil and residues are shown at specific final boiling point (FBP) temperatures of 70 °C, 70 °C - 110 °C, 110 °C - 221.1 °C, 221.1 °C - 304.4 °C, 304.4 °C - 371.1 °C, 371.1 °C - 537.8 °C and 537.7 °C respectively. Whereas, above a temperature of 300 °C, the weight percentage of aromatic components increased steadily. The increase in percentage composition of the aromatic components is due to the reduction of the paraffinic components. The density of the liquid bio-oil was steadily increasing until a temperature of 200 °C.

Published: April 2024

INTRODUCTION. In the Russian Federation, among all malignant diseases in the male population, gastric cancer ranks the 4th, in women – 5th place, and in terms of mortality in both sexes from malignant diseases – 2nd place. During surgical treatment  of  patients  with gastric cancer, anemia is detected in more than 1/4 of  patients, who significantly worsens the prognosis due to postoperative complications. Timely correction of anemia can reduce the risk of complications during surgical treatment and improve the course of the postoperative period.

OBJECTIVE is to evaluate the effectiveness of correction of anemia in the preoperative period and the results of radical surgical treatment in patients with gastric cancer

METHODS AND MATERIALS. The article presents the analysis of medical records of 30 patients aged 56–75 years with a diagnosis of gastric cancer complicated by anemia (hemoglobin level < 80 g/l). All patients in the preoperative period for the correction of anemia were prescribed iron (III) hydroxide oligoisomaltose intravenously at the dose of 20 mg/kg 21 days before surgery, due to the detection of iron deficiency in them.

RESULTS. The target blood hemoglobin level was more than 95 g/l. In the absence of the desired effect, erythrocyte transfusion was performed. The use of iron preparations made it possible to correct anemia in 14 (46.7 %) patients without resorting to transfusions, in 16 (53.3 %) patients, it was required to additionally transfuse 1 dose of erythrocytes, while earlier in the preoperative anemia was corrected using transfusions of 2–3 doses of erythrocytes. All patients underwent radical surgery with D2 lymph node dissection. Operations were accompanied by blood loss of 201.0±94.4 ml (120–475 ml). It was revealed that radical surgeries for gastric cancer in patients who received anemia correction in the preoperative period are accompanied by a low number of purulent-inflammatory (in 27.3 % of patients) and cardiovascular complications (in 20 % of patients).

CONCLUSION. Correction of anemia is a mandatory part of therapy in the preoperative period and allows to perform a full range of radical surgical intervention, improve the safety of surgical treatment and improve the course of the postoperative period.
Hernia of the xiphoid process
Authors: Ivlev V. V.
Published: April 2024

Hernia of the xiphoid process refers to rare variants of hernial protrusion. For the period from 1914 to the present, only 11 cases have been described in the official Russian-language literature. Hernial gates are either a defect of a rounded shape directly in the xiphoid process, or splitting of the xiphoid process by the type of «horns». The contents are most often preperitoneal lipoma, and 2 cases have also been described when the contents were a strand of the large omentum and a fatty appendage of the transverse colon. The risk of infringement with such hernias is minimal. Operational tactics, despite the development of modern minimally invasive techniques, still remains controversial due to the peculiarities of the fit to the xiphoid process of the peritoneum and the thoracic own fascia to the periosteum of the sternum process. This paper presents a clinical case of a patient sought medical help for an increase in education in the xiphoid process within 4 months.

Published: April 2024

INTRODUCTION. The article describes the analysis of the Russian experience in the treatment of Amyand’s and De Garengeot’s hernias and the author’s observation of an extremely rare case of appendix incarceration in the right femoral hernia. The hybrid surgery was performed – open herniotomy for appendectomy of the distal part of the appendix and the laparoscopy to remove the remaining intraabdominal part of the appendix.

The OBJECTIVE was to describe the treatment tactics for the Amyand’s and Garengeot’s hernias based on the analysis of data from the Russian literature and our own clinical experience.

METHODS AND MATERIALS – review of the Russian literature and own clinical case.

RESULTS. 22 cases of Amyand’s hernia and only one of Garengeot’s hernia cases in 14 articles was found. CONCLUSION. The terms «Amyand’s hernia» and “Garengeot’s hernia” mean the development of acute appendicitis in cases of the location of the appendix in the hernial sac in inguinal or femoral hernias, respectively, and are also valid in cases of incarceration of these hernias, the contents of which are a secondarily modified as a result of incarceration of the appendix. Urgent surgical interventions for Amyand’s and De Garengeot’s hernias could be performed by traditional, laparoscopic and hybrid methods, depending on the preoperative diagnosis and intraoperative features.

Published: April 2024

El uso racional del recurso hídrico está plasmado como una meta global en los objetivos de desarrollo sostenible (ODS), lo cual trae múltiples beneficios a los diferentes actores involucrados en la gestión integral de los recursos hídricos. Los programas de uso eficiente y ahorro del agua (PUEAA) contemplan una serie de actividades y metas que tienen por propósito contribuir a la sostenibilidad del recurso hídrico; de ahí la importancia de hacer un seguimiento a través de indicadores de cumplimiento que permitan recopilar información, tanto de las empresas como de las autoridades ambientales, con relación a su gestión. En este artículo se analiza la aplicación de la Ley 373 de 1997, en lo que se refiere al seguimiento de los PUEAA, en el Departamento de Nariño, durante el periodo 2015 a 2018. Para el desarrollo de esta investigación se realizó un inventario de los términos de referencia municipales de los proyectos formulados y ejecutados por las empresas de servicios públicos de agua (ESP). Se aplicaron indicadores de eficiencia y efectividad y se evaluaron los resultados con una matriz de cumplimiento. Los resultados mostraron que la línea estratégica de reducción de pérdidas presenta las deficiencias más significativas en la formulación y seguimiento de los PUEAA en el departamento (0% de cumplimiento). Mientras que la línea estratégica de educación y sensibilización ambiental para uso eficiente del agua presentó mejores resultados en sus indicadores (cumplimento mayor al 50%). Dentro de las conclusiones se tiene que, los bajos niveles observados en los indicadores están relacionados con la pérdida y falta de organización en la información de los expedientes de los PUEAA, tanto por la autoridad ambiental como por los usuarios (ESP), debido a la falta de conocimiento de los términos y exigencias de la Ley 373 de 1997.
Detección de acción humana para el control de inventario utilizando visión por computadora
Authors: Bernal Baquero Francisco , Martínez Darwin E.
Published: April 2024

La visión por computadora (VC) puede ser un proceso que facilite algunas tareas en la gestión de inventarios, por medio de este proceso se puede realizar un análisis permanente de un inventario y así mantener registro de todos los movimientos realizados, entregando un reporte instantáneo cuando sea requerido. Esto supone una mejora en la seguridad, ya que al mantener un control estricto de los elementos existentes en el inventario se puede saber si un elemento pertenece o no a un inventario o cuando se retira o agrega un elemento, tras esta necesidad de control de inventario, surge la necesidad de diseñar un sistema inteligente que pueda facilitar el control de inventarios. Mediante la combinación de 2 frameworks, se realiza la creación de un algoritmo capaz de realizar la identificación y conteo de objetos, así como la identificación de la mano para determinar cuándo se realiza una manipulación humana al inventario. Para lograr este objetivo, se utilizaron dos algoritmos: MediaPipe y YOLOv5 combinado con el dataset de COCO, el primero se usó para la detección de manos y el segundo identifica y cuenta los objetos. Después de las pruebas realizadas al algoritmo se determina que el reconocimiento de manos de MediaPipe tuvo una precisión del 96% y la detección y clasificación de objetos usando YOLO fue de 43.7%. Teniendo como retos el algoritmo la superposición, la oclusión/auto oclusión de los objetos, o la pérdida de foco de los elementos debido al sensor.
Aspectos neurocognitivos do alcoolismo
Authors: Caixeta Leonardo Ferreira , Prestes Leonardo da Silva , Oliveira Tiago Batista de , Silveira Erika Aparecida , Barbosa Maria Alves , Baldaçara Leonardo
Published: April 2024

Introdução: O uso prolongado e excessivo de álcool pode acarretar danos cerebrais estruturais e funcionais, ocasionando déficits cognitivos. As repercussões cognitivas mais conhecidas do alcoolismo foram descritas por psiquiatras: a síndrome de Wernicke (SW), a amnésia de Korsakoff (AK), e a Demência Associada ao Alcoolismo (DAA). Métodos: Trata-se de uma revisão narrativa acerca dos  aspectos cognitivos relacionados ao alcoolismo, com ênfase na DAA. Resultados: A SW é composta por uma tríade de oftalmoplegia, marcha atáxica e alterações no estado mental. A AK é uma síndrome residual após a SW, caracterizada por amnésia global, confabulações e alterações de comportamento. A DAA é uma síndrome orgânica com quadro de grave disfunção cognitiva, disfunção executiva, dificuldade no controle emocional e comprometimento da memória. Ainda atualmente há dúvidas quanto à etiopatogenia, status nosológico, prevalência e critérios diagnósticos para a DAA, devido à dificuldade de avaliação e a diversos fatores de confusão, portanto a compreensão atual dessa forma de demência permanece limitada. Conclusões: A DAA é uma forma de demência geralmente pré-senil e até certo ponto reversível, podendo ser classificada do ponto de vista neuroanatômico como córtico-subcortical e se manifestando clinicamente com sintomas amnésticos, frontais-disexecutivos, cerebelares e subcorticais. Até que tenhamos uma maior compreensão dos mecanismos fisiopatológicos da DAA, é altamente improvável que seja desenvolvido um conjunto único e reprodutível de critérios diagnósticos.

Twenty hybrids along with five parents evaluated in the study were mainly contemplated to find out the best cross combinations and the best general and specific combiners as well as to estimate the nature and magnitude of the gene action for different qualitative traits. Using Griffin’s and Hayman’s approach through a 5 X 5 full diallel cross fashion, an investigation on heterosis and combining ability in pumpkin was undertaken following RCBD design with three replications at the experimental field. Both positive and negative significant GCA and SCA variances were obtained from few parents and hybrids. Predominance of additive-additive gene action was noted for most of the characters except hollowness and dry matter content, where additive-dominance gene action was predominant; flesh thickness and brix (%), where dominance- dominance gene action were predominant. A single parent was not found as good combiner for more than two characters. The best specific combiners were IBD 40 X IBD 47 for beta-carotene, total sugar and fruit yield; IBD23 X IBD40 for brix (%), hollowness and flesh thickness; IBD40 X IBD57 for fruit breadth; IBD47 X IBD50 for non-reducing sugar; and IBD47 X IBD57 for reducing sugar. The Vr- Wr graphs exhibited complete, partial and over dominance effect of genes for different characters. Complete dominance was observed only for beta-carotene whereas over dominance was noticed for hollowness and flesh thickness. Partial dominance was ensured for fruit breadth, dry matter, brix (%), reducing sugar, non-reducing sugar, total sugar and fruit yield. Significant heterosis of some crosses against mid parent and better parents were observed for some characters.

Published: April 2024

In Ethiopia, many varieties were released to improve field pea yield at different locations. However, field pea’s productivity is low because the released and improved varieties were not demonstrated at farms. Therefore, demonstrating improved field pea varieties is an entry point to large extension production. Hence, this study was conducted in three highland districts of the Guji zone to evaluate the yield and profitability of kik type field pea varieties on farmer’s land. An improved variety named Burkitu and local varieties were demonstrated on 12 experimental farmers in 2022. Yield data and production costs were collected and analyzed by descriptive statistics, and the profitability of varieties were estimated by cost benefit analysis. The results showed that kik type Burkitu variety generated a yield of 23.58 qt/ha compared to 18.33 qt/ha of local variety. The result of cost benefit analysis also indicated that Burkitu (97005 birr/ha) variety gave better returns than the local variety (54022 birr/ha). Based on higher yield, disease tolerant and market demand Burkitu variety was preferred by farmers. Using improved field pea varieties was important for higher yield and return. Hence, farmers should use Burkitu for kik type field pea production. Further research is needed to promote Burkitu as scaling up varieties in the highland areas of the Guji zone.

Published: April 2024

Surfactant-free colloidal syntheses in aqueous media are attractive to develop nanomaterials relevant for various applications, e.g. catalysis or medicine. However, controlled green syntheses without surfactants of metal nanoparticles in aqueous media remain scarce. Here, room temperature syntheses of gold (Au) nanoparticles (NPs) that require only HAuCl4, alkaline water and an alcohol, i.e. relatively benign chemicals and mild reaction conditions, are developed. The findings of a comprehensive multi-parameters screening performed in small volumes (< 3 mL) over 1000+ experiments, that pave the way to greener high throughput screening of large parametric spaces and leads to scalable (100 mL) synthetic strategies, are summarized. A rational selection of the alcohol is proposed. The influence of lights with defined wavelengths (222-690 nm) is investigated. It is found that lights with lower wavelengths favor the formation of smaller 5 nm NPs. Different kinetics and formation pathways are observed for different alcohols and for lights with different wavelengths. The sensitivity to various experimental parameters increases in the order glycerol < ethylene glycol < ethanol < methanol. New strategies for a rational fine size control, and to some extend shape control, are identified. The results lead to more sustainable and reproducible surfactant-free colloidal syntheses of NPs.

Meayamycins are synthetic analogs of the natural product FR901464 and exhibit potent anticancer activity against human cancers. They bind SF3B1 and PHF5A, components of the human spliceosome, and alter pre-mRNA splicing. Detailed analysis of the active site led us to investigate a narrow pocket within the binding site which surrounds the ,-unsaturated amide portion of meayamycin. We describe the synthesis and biological activity of two new analogs bearing a methyl substituent on the or position of the amide. With these analogs, we investigated the discrete interactions within the narrow region of SF3B1 using a human/yeast chimeric SF3B1 protein and found the V1078 residue of SF3B1 affects compound binding at the amide moiety.

We report the conformational control of 2D ultra-thin indium sulfide nanoribbons by tuning their amine ligands' alkyl chain. The initial orthorhombic InS nanoribbons bare octylamine ligands and display a highly curved geometry with a characteristic figure of eight shapes. Exchanging the native ligand by oleylamine induces their complete unfolding to yield flat board-shaped nanoribbons. Significant strain variations in the InS crystal structure accompany this shape-shifting. By tuning the linear alkyl chain length from 4 to 18 carbon atoms, we show using SAXS in solution and TEM that the curvature of the nanoribbon subtly depends on the ligand-ligand interactions at the nanoribbon's surface. The curvature decreases gradually as the chain length increases, while carbon unsaturation has an unexpectedly significant effect at constant chain length. These experiments shed light on the critical role of the ligand monolayer on the curvature of ultrathin 2D crystalline nanosheets and demonstrate that weak supramolecular forces within the organic part of colloidal nanocrystals can dramatically impact their shape. This transduction mechanism, in which changes in the organic monolayer impact the shape of a nanocrystal, will help devise new strategies to design stimuli-responsive systems that take advantage of both the flexibility of organic moieties and the physical properties of the inorganic core.
Boosting Prediction of Protein-Protein Interactions using Word Embedding Techniques
Authors: Nguyen Tuong Tri
Published: April 2024

Understanding protein-protein interactions (PPIs) helps to identify protein functions and develop other important applications such as drug preparation, protein-disease relationship identification. Machine learning methods have been developed for the PPI prediction task in order to reduce the cost and time of previous experimental methods. In this paper, we study a method for determining PPIs using deep learning and protein sequence representation learning. In our method, an word embedding technique is utilized for protein sequence representation learning. This technique captures the semantic relationship between amino acids in protein sequences. The semantic relationship is then used as the input information, which is fed into a neural network to help recognize the interaction signature of the input protein pair. Different from previous studies, we integrate the protein sequence embedding mechanism into a neural network model. Thereby, the protein sequence embedding is better controlled for PPI prediction by our neural network model. We evaluate our method on benchmark datasets including Yeast, Human, and eight different independent sets. In addition, we also conduct an extensive comparison with the other existing methods. Our results show that the proposed method is superior to other existing methods and achieves high efficiency in predicting cross-species PPIs. The dataset and our source code are available at https://github.com/thnhub/BoostPPIP.git.

Abscess is a collection of the pus in cavity and it is an acquired condition seen all over the body. The clinical features of abscess are swelling pain redness tenderness and local temperature. The aggravated Dosha vitiate the skin blood muscles fat and bone tissue become localised and produce a troublesome swelling - deep rooted painful slowly bulging called Vidhradhi. When this Vidhradhi completes its pakwa avasta it burst opens or we have to do bedhana karma to drain vitiated substances leading to a cavity. The clinical features of Vidhradhi presenting swelling pain redness local temperature can be correlated to abscess The abscess which is developed in perianal regions is called perianal abscess. There are many theories has been explained regarding causative factors for perianal abscess and fistula in ano. However in most of the cases perianal abscess always ends up into forming a fistula in ano. Here in this case the Ayurvedic management of pratisaraniya kshara was applied post I and D considering it as a Dusta Vrana keeping in the mind to avoid the reoccurrence and fistula in Ano formation.nbsp

Milk and dairy products contain saturated fatty acids that have different effects on human
health status and are risk factors for many diseases including cardiovascular disease and
diabetes mellitus. The present study aimed to evaluate the impact of creamy and skimmed
milk administration and certain dairy products (yoghurt and cheese) on healthy rats. A
total of forty-nine healthy male Sprague Dawley rats were divided to seven groups. The
treatment diet includes creamy and skimmed milk, creamy and skimmed yoghurt, creamy
and skimmed cheese. After 60 days of consumption, body weight (BW) and lipids profile
were measured. The final BW was higher in rats fed with creamy milk (256.40±23.81),
and rats fed with creamy yoghurt (262.71±25.41) and creamy cheese (266.57±22.71). A
significant elevation in the liver (aspartate aminotransferase and serum alanine) and
kidney functions (urea, creatinine, and uric acid) have been observed in rats fed with fresh
creamy whole milk and skimmed milk groups. The measured lipid profile has increased,
especially rats fed with creamy milk, creamy, and skimmed cheese. In which, the total
cholesterol has reached 159.70, 170.11 and 160.11. Meanwhile, the triglycerides increased
to 125.51, 117.35 and 110.41. The low-density lipoprotein and the very low-density
lipoprotein have also elevated with their atherogenic indexes at 5.2±0.55, 5.74±0.68 and
5.31±0.44 respectively. On the other hand, notable decreases were seen in the high-density
lipoprotein cholesterol and liver glycogen compared to rats fed with control diet. In
conclusion, both skimmed and creamy yoghurt indicated healthy nutritional properties,
especially with lipid and atherogenic indexes by means of healthy liver and renal
functions. Thus, yoghurt (creamy or skimmed) improved the healthy rats' lipid profile
while creamy milk additions increased the BW. However, cheese (creamy or skimmed) is
suggested to be avoided due to hyperlipidemic conditions in rats.
