Association between preoperative lumbar skeletal muscle index and postoperative nausea and vomiting in patients undergoing pylorus-preserving pancreatoduodenectomy: a retrospective study
Authors: Kim Hyun Il , Kim Ki Jun , Kim Sangil , Kim Hae Dong , Kim Seung Hyun
Published: April 2024

Background: Sarcopenia is associated with postoperative complications; however, its impact on the quality of postoperative recovery, such as postoperative nausea and vomiting (PONV) and pain, remains unclear. We investigated the association of preoperative lumbar skeletal muscle mass index (LSMI) with PONV, postoperative pain, and complications.Methods: Medical records of 756 patients who underwent pylorus-preserving pancreatoduodenectomy (PPPD) were retrospectively reviewed. The skeletal muscle areas were measured on abdominal computed tomography (CT) images. LSMI was calculated by dividing the skeletal muscle area by the square of the patient’s height. We analyzed the correlations between preoperative LSMI calibrated with confounding variables and PONV scores, PONV occurrence, pain scores, rescue analgesic administration, postoperative complications, and length of hospital stay.Results: The median (1Q, 3Q) LSMI was 47.72 (40.74, 53.41) cm2/m2. The incidence rates of PONV according to time period were as follows: post-anesthesia care unit, 42/756 (5.6%); 0–6 h, 54/756 (7.1%); 6–24 h, 120/756 (15.9%); 24–48 h, 46/756 (6.1%); and overall, 234/756 (31.0%). The incidence of PONV was inversely correlated with LSMI 24–48 h post-surgery and overall. LSMI and PONV scores were negatively associated 6–24 h and 24–48 h post-surgery. There was no association between LSMI and postoperative pain scores, rescue analgesic administration, complications, or length of hospital stay. Conclusions: Preoperative LSMI was associated with PONV in patients undergoing PPPD. Therefore, LSMI measured on preoperative abdominal CT can be a predictive indicator of PONV. Appropriate PONV prophylaxis is necessary in patients with low LSMI before PPPD.

Published: April 2024

The island of Cyprus hosts a rich diversity of reptiles, including several endemic species. Reptiles are morecommon in Mediterranean-type shrubland and other open habitats in Cyprus, although riparian formations offeradditional cover and food sources, especially during dry, hot summers. Riparian habitats are often very heterogeneous,an attribute that can be important for lizards since they can utilize a variety of microhabitats crucial for different aspectsof their ecology. Nevertheless, reptilian diversity in riparian systems remains understudied and Cyprus is no exception.The aim of this study was to compare lizard diversity and abundance patterns across seasons and elevations, as well astheir relationships with habitat heterogeneity and protected status of areas along riverbanks, as expressed by presencein or out of Natura 2000 sites. We examined the effects that these factors can have on lizard communities by studyingthree rivers that exhibit variations in environmental conditions. Additionally, we evaluated separately the abundancesof four common species (Snake-eyed Lizard, Ophisops elegans; Troodos Rock Lizard, Phoenicolacerta troodica; CyprusRock Agama, Laudakia cypriaca; and Schreiber’s Fringe-toed Lizard, Acanthodactylus schreiberi) while recording in riparian habitats seven of the 11 Cypriot species of lizards. Diversity and richness were not significantly associated withany of the explanatory variables examined (season, elevation, habitat heterogeneity, and protected status). Moreover,we found no relationship between the abundances of each of the four species and habitat heterogeneity, even thoughthey responded differently to elevation, season, and protected status. Our results suggest that lizard diversity in ripariansystems is high compared to the total number of lizard species found on Cyprus, reaching 60% of the overall richness.
Conservation of two freshwater turtle species in the Guru Gorakhnath Community Reserve in Western Haryana, India
Authors: Delu Vikram , Karwasra Vinod , Panda Ashish
Published: April 2024

The active involvement of local communities in conservation efforts is pivotal in ensuring the long-term protection and preservation of our natural environment. In the village of Kajalheri, located in Fatehabad district, the environmentally conscious Bishnoi community has been engaged in the conservation of the Indian soft-shell turtle (Nilssonia gangetica) population in the village pond for nearly a century. As a testament to their efforts, the pond was officially designated as a community reserve in 2019 to safeguard these turtles. Previously, the Indian soft-shell turtle was the sole known species inhabiting this small pond. However, our observations from 2021 to 2023 have revealed the presence of two additional turtle species, namely the Indian tent turtle (Pangshura tentoria) and the Indian roofed turtle (Pangshura tecta). No study on freshwater turtles specific to the Haryana region has been carried out. Therefore, baseline data on the diversity and distribution of freshwater turtles is scanty in the state. This scientific inquiry provides valuable insights into effective habitat management strategies and instils hope for identifying similar sites within the forest-deficient state of Haryana.
Compromiso cristiano y su relación con la parentalidad y conyugalidad en una muestra de feligreses adventistas del Perú
Authors: Mera Guevara Roger
Published: April 2024

La conyugalidad establecida por la cantidad de matrimonios legales realizados ha disminuido en los últimos años, pero además sufre los embates del divorcio que ha subido en cantidades alarmantes. Esta situación afecta la parentalidad, y especialmente entre los cristianos se nota en la deserción de los hijos de la fe de los padres. Asimismo, se observa un decrecimiento en el compromiso cristiano de los feligreses activos en las iglesias cristianas. El objetivo de esta investigación ha sido determinar la relación que existe entre compromiso cristiano, conyugalidad y parentalidad de los feligreses adventistas casados. Para ello se realizó una investigación de diseño no-experimental y de corte transversal en una muestra de 519 feligreses adventistas en la provincia del Callao, zona norte de la provincia de Lima y la provincia del Santa. Los resultados confirmaron que existe una correlación fuerte y directa entre compromiso cristiano y la conyugalidad (coeficiente de Rho de Spearman de 0.586) y compromiso cristiano y parentalidad (Rho de Spearman de 0.578). Se concluye que si el compromiso cristiano mejora, también mejora la conyugalidad y parentalidad.

Padányi Bíró Márton, a nagy lángon égő, ellentmondást nem tűrő, hitvitázó püspök egész életében elszántan harcolt a katolikus vallás megerősítéséért és a török idők utáni veszprémi egyházmegye újjáépítéséért. Tette mindezt szóval és tettel, új templomok építésével, régiek felújításával, új plébániák szervezésével, nagy hatású prédikációival. Hittérítő tevékenységét azonban nemcsak szóban és írásban folytatta, hanem a képzőművészetet is segítségül hívta, így került Magyarországra Franz Anthon Maulbertsch osztrák freskófestő, akinek képein keresztül is terjeszthette az igét. Veszprémi székhelyét Sümegre helyezte át, még ha a várat nem is sikerült rezidenciájává alakíttatnia, a ferences  kolostor mellett álló épületet viszont igen. Itt rendezte be könyvtárát. Padányi Bíró Márton termékeny szerző volt, hitvitáit, szentbe szédeit nagyrészt magyarul vetette papírra, nagyszámú levele is ismert. Számos könyve közül a leghíresebb az 1750-ben megjelent Enchiridion című műve, amelyben a protestáns felekezetek, vagyis az ő értelmezésében az „eretnekség” megszüntetésére vonatkozó módszerét foglalta össze. E könyvével rosszul mérte föl a politikai erőteret, elveszítette Mária Terézia addigi pártfogását, ami nemcsak pályájának, hanem személyének megtöréséhez is vezetett.
Species of the Poaceae family suitable for Andean livestock farming in the Peruvian Andes reported in GBIF and local studies
Authors: Raul Marino Yaranga Cano , JA Orellana , SE Pizarro
Published: April 2024

Andean grassland ecosystems are covered by a mega-vascular floristic diversity constituted by families such as Poaceae, Rosaceae, Asteraceae, Plantaginaceae, Fabaceae, and Cyperaceae, among the most important ones that include suitable species for Andean Livestock feeding such as sheep, cattle, and South American camelids. However, the accelerated degradation of ecosystems and the extinction of several important species, have put it in our interest to know better the spatio-temporal distribution of these species as a starting point for spatio-temporal monitoring. With this purpose, we compiled information on those identified as D species in the Poaceae family, from thesis studies and published scientific articles. We also examined the record and spatial distribution of D species of this family in the Global Biodiversity Information System (GBIF) corresponding to the Sierra region of Peru. Specific geo-processed maps were generated after data curation. It was found that there are 63 D species included in the genus: Agrostis, Agropirum, Bromus, Calamagrostis, Dissanthelium, Festuca, Hordeum, Muhlenbergia, Nasella, Paspalum, Poa, Stipa, Trisetum and Vulpia, of which only 52 species are registered in GBIF, noting the concentration of records in places of greater tourist interest and with funded research projects such as the Huascaran National Park and others. The few studies on natural grassland species in Peru and the low spatial coverage of the species recorded in GBIF still limit the generation of adequate monitoring strategies.

Authors: Vegar Zubović Sandra , Kristić Spomenka , Sefić Pašić Irmina
Published: April 2024

Aim
 To investigate a correlation between calculated creatinine clearance as a measure of kidney’s functional abilities and ultrasonographically determined kidney volume, which represents actual size of the kidney, in fact residual renal mass in chronic kidney disease, in order to determine possibilities of ultrasound as a diagnostic method in diagnosing and follow up of chronic renal disease.
Methods
 Prospective study included 150 patients with registered demographic and anthropometric data, and also with relevant laboratory tests of renal function. Longitudinal diameter, thickness and width of the kidney and renal volume calculated according to the Dinkel’s formula were measured by ultrasound. A correlation between the measured volume of the kidneys and calculated creatinine clearance was done by the Spearman method, with statistical significance of p<0.05.
Results
 Statistically significant correlation between the estimated creatinine clearance values and the average of the calculated values of kidney volume was found (p<0.01). Average value of the kidneys’ volume showed a linear decrease with the progression of chronic kidney disease: the kidney volume in the control healthy group was 171.7 ± 32.6 mL (95.22- 229.59 mL), and in the subjects classified in stage IV it was 74.7 ± 24.6 mL (43.22-165.65 mL).
Conclusion
 Calculated volume of kidney well correlated with creatinine clearance as a measure of functional ability of the kidneys
and with the stage of chronic renal disease. It can be used in clinical practice for monitoring of chronic kidney disease in conjunction with other clinical and laboratory parameters

Published: April 2024

In sport, classifying players during the training period according to their year of birth generates inequalities in terms of the number of learning opportunities. This study investigates the effect of relative age at the highest levels of Spanish handball. Its presence is analyzed and it is observed whether gender and nationality variables influence it. For this purpose, the dates of birth, gender and nationality of 1141 male and female players in the two main Spanish leagues (Liga ASOBAL and Liga Guerreras Iberdrola) were collected during 3 seasons. After classifying them by year of birth, assuming an equitable distribution, the results only showed significant differences in the case of male handball (χ² = 5.04; p = 0.02) with a RAE Coefficient value of 1.20. The distribution in the case of female players was more homogeneous. When observing the sample based on nationality, the greatest differences occurred in foreign players (χ² = 7.20; p = 0.01) with a RAE Coefficient value of 1.45. Therefore, it can be stated that the RAE due to the year of birth only influences Spanish elite men's handball, caused by those international players who play in the ASOBAL League teams. The presence of these foreign athletes is the cause of the only differences observed between the groups analyzed.

Reading is a key skill in any type of learning process. Spanish students´ results are low in national and international assessment scales. Reading processes are complex and the skill transferences between languages are not always positive. This action-research study analyses a fourth primary students´ population with Spanish as the language of schooling and English as a foreign language. The research instruments used were phonemic awareness, literacy and vocabulary tests. It is shown that, when a reading intervention programme is carried out with English subtitled musical videos, phonemic awareness improves as sounds, prosodic elements and vocabulary are practiced. Students improve their reading fluency, text comprehension and their learning motivation.
Light Sheet Fluorescence Microscopy of Human Kidney Using Clearing with CUBIC v1
Authors: Mclaughlin Liam , Knoten Amanda , Jain Sanjay
Published: April 2024

Light sheet fluorescence microscopy (LSFM) is a method to cover micro-mesoscale (µm-cm) areas of tissue while achieving depth of several millimeters to enable 3D-volumetric imaging of tissue structures or organs. By using fluorescence tagged primary or secondary immunofluorescence it is capable of provides cellular resolution and anatomical maps. Compared to traditional laser confocal microscopy imaging LSFM, LSFM provides rapid acquisition of images over large optically cleared tissues while maintaining high resolution. As compared to serial 3D reconstruction, In toto imaging by LSFM provides a more accurate 3D dataset that captures the spatial relationships between structures and cells. Application of LSFM to adult human tissues, particularly solid tissues such kidney, is challenging due to its complex anatomical organization and composition, heterogeneity and interstitium. The relationships between extracellular and extrarenal structures have not been defined. This knowledge is critical to understand how different functional tissue units of the kidney are organized in 3D as key interactions and signaling necessary for its physiological roles cannot be correctly derived from 2D images. Here we describe a protocol we developed to aid in 3D visualization of kidney cells, functional tissue units and their relationship with nerves, vasculature and lymphatics as a goal in HuBMAP consortium to create 3D reference maps. After testing several protocols, here we describe a clearing method on tissue slices in conjunction with immunofluorescence staining o visualize deep kidney volumes (1-3mm depth) when imaged by light sheet microscope. We provide several tips during tissue preparation for clearing, clearing procedure and an example of imaging the tissue using LSFM. We also briefly discuss various outputs of imaging and metadata files that can be used for data submission or for publishing or hosting on external servers. The imaging section contains the following: 1)Refractive Index (RI) matching tissue with Refractive Index Matching Solution (RIMS), 2) Capturing a full-volume 5x image, 3) Capturing 20X images of regions of interest (ROIs), 4) Stitching and down sampling images prior to analysis, 5) Different file formats. All imaging was completed using a Zeiss Lightsheet 7 microscope.

Comparative Analysis of Stochastic and Uncertain Process Degradation Modeling Based on RQRL
Authors: Liu Kai , Zou TianJi , Xin Mincheng
Published: April 2024

Small sample sizes cause epistemic uncertainties in reliability estimation and even result in potential risks in maintenance strategies. To explore the difference between stochastic- and uncertain-process-based degradation modeling in reliability estimation for small samples, this study proposes a comparative analysis methodology based on the range of quantile reliable lifetime (RQRL). First, considering both unit-to-unit variability and epistemic uncertainty, we proposed the Wiener and Liu process degradation models. Second, based on the RQRL, a comparative analysis method of different degradation models for reliability estimation under various sample sizes and measurement times was proposed. Third, based on a case study, the sensitivities of the Wiener and Liu process degradation models for various sample sizes and measurement times were compared and analyzed based on the RQRL. The results demonstrated that using the uncertain process degradation model improved the uniformity and stability of reliability estimation under small-sample conditions.

Authors: Lenarčič Katja , Jug Došler Anita , Mivšek Ana Polona
Published: April 2024

Introduction: The COVID-19 epidemic and its restrictions have affected all aspects of people’s lives, including health-related quality of life and, considering sexuality as an integral part of individual needs, also intimacy and sexuality. Therefore, the aim of this article was to investigate women’s sexual functioning and health-related quality of life assessment in Slovenian women in the reproductive period.
Methods: An online survey with valid questionnaires (short form 36 [SF-36] and Female sexual function index [FSFI-19]) was conducted in January 2022. All research ethical measures were taken to ensure the integrity of the participants.
Results: The FSFI scale score was 25.37 ± 8.29, 1.18 points above the cutoff point, indicating a higher risk of sexual dysfunction (26.55). The estimated prevalence of sexual dysfunction was 36.8%, with sexual desire being the most problematic area. The mean score on the SF-36 scale in our sample reached 73.52 ± 13.84 on a 100-point scale, with 0 representing the worst and 100 the best quality of life; fatigue (x̅ = 48.50) was the most problematic category. The results partly reflect the results of foreign studies, but we must be aware of cultural differences in the understanding of sexuality and keep in mind that some countries faced difficult circumstances during the COVID-19 pandemic and that social constraints were different in 2020 than in 2022.
Conclusion: The epidemic affected the sexual function of women of reproductive age and their perception of (health-related) quality of life.

Published: April 2024

Nociception pathway is thought to be pre-emptively inhibited in hope to reduce acute pain in an anticipated procedural related tissue injury intraoperatively or postoperatively when pre-emptive analgesics are administered preoperatively. High intensity of pain is expected after surgical removal of the third molar which is associated with jaw swelling and limited opening of the jaw. We compared the pre-emptive analgesia effect of oral celecoxib and oral tramadol in elective ambulatory dental surgery under general anaesthesia. Informed consents were obtained from 84 patients with American Society of Anesthesiologists (ASA) physical status I or II and aged between 18 to 56 years. They were randomised to receive either oral celecoxib 200 mg (Group A) or oral tramadol 50 mg (Group B) one hour before induction of anaesthesia. Intraoperative and postoperative fentanyl consumption were compared. Numeric Rating Scale (NRS), ranging from 1 to 10, was used to assess postoperative pain scores. Group A showed a significant reduction in fentanyl consumption intraoperatively compared to Group B (p=0.047). Both groups of patients experienced mild pain at various times assessed postoperatively ranging between 0-2 NRS scores. Comparison between the groups did not detect significant reduction in pain scores and postoperative fentanyl consumption. We concluded that neither medication was found to be effective as pre-emptive analgesia, however, intraoperative fentanyl consumption was reduced by pre-emptive administration of oral celecoxib.

A Review of Friction Stir Welding and Processing on Aluminium Alloys
Authors: Parkhe Shailesh S. , Patil Rupesh J.
Published: April 2024

To combine extra-strong aircraft aluminium alloys that are typically difficult to fuse using standard fusing methods of welding, a unique sustainable solid-state combining method known as Friction Stir Welding (FSW) is used. In contrast to certain other solid-state combining techniques, friction stir welding involves a third intimate contact with the tools, which creates extra interfacing areas. Ultimately, all of these areas merge under the application of heat and pressure to produce a solid-state joint. This systematic review discusses the fundamental principles of friction stir welding and processing on AA3000 series material, the creation of microstructures, the sensible processing conditions, frequent FSW flaws, as well as some application fields. Additionally, the article will cover a few FSW process variations; including friction stir processing and friction stir spot welding. The processing parameters were determined to be at their best using the Taguchi Technique (TT). The research also examined the microstructures on FSW specimens at the optimum point, welding zone hardness, and union effectiveness of the FSW joint. The efficiency and dependability of welded joints for operations in the shipbuilding industry may be shown by joint reliability. That was examined under ideal circumstances, and it turned out to be 85%.

The outline idea is based on saddling the high quality and wear capacities of eminent engineered fortifications, for example with the lightweight and minimal effort of preparing or squandering fiery remains. There is almost no writing which has considered the outline of Aluminium Matrix Composites (AMCs) with the utilization of fortifications of agro squander slag. The Scanning Electron Microscope (SEM) images of gleaming samples, the subsequent were examined. The distribution of strengthening flecks (Mullite (Al2O3 -SiO2 )) is recovered to be steady. Mullite specks are not confined to the grain frontiers. From the wear studies of Al4006 alloy, it was observed that there was more wear out of the surface when compared to Al4006/ Al2O3 -SiO2 composites. Wear tracks of Al4006 alloy show a tough face with extra grooves and ridges associated with wear tracks of Al4006/Al2O3 -SiO2 composites dispersion and binding of the Al2O3 -SiO2 in the composite could indeed be explained by the reduced wear rate. Also, the addition of cenospheres acts as a load-bearing material which protects the matrix from more wear out. Wear track investigation described more wear out and deep abrasive trenches in as-cast contrasted to that of composites which may be due to the lack of load-bearing reinforcing material (mullite) which worsens the material strength leading to more tear or wear out. Overall, from the current studies, it can observed that as the mullite particle reinforcement increases the matrix hardness, strength, and density increase. This study highlights the essential characteristics of the technique of liquid metallurgy and its application to Al4006 MMCs reinforced with mullite.

Renewable energy systems are of high importance considering the present day energy requirement. In Wind energy systems design and analysis of wind turbines for enhanced efficiency at low at wind speed is studied in this paper. Aero foil shape is the one of the key aspects which determines the efficiency of the turbine. In this paper airfoil G4510, NACA 0018 and NACA 4412 are considered for the study with a blade length of 0.762 m. General Public Licensed Software QBlade is used for the simulation which uses Blade Element Method (BEM). Comparison of performance parameters for different aero foil is presented and blade is designed using G4510 airfoil nomenclature. Using these blades, a three bladed rotor is assembled and structural analysis is performed to know the pressure distribution on different areas of the blade. Finally, a tower is attached to the rotor assembly and simulation is carried on the small wind turbine. Graphical relationship between power, tip speed ratio, velocity and coefficient of pressure is obtained for analysis.

In this study, experiments are carried out to explore the impact of incorporating Diethyl Ether (DEE) as an additive into biodiesel-Straight Vegetable Oil (SVO) blends derived from Pongamia seeds. Our objective was to assess the influences of additives on the engine performance characteristics of a CI engine. The different fuel blends such as BD80+SVO15+DEE5 (comprising 80% biodiesel, 15% SVO, and 5% DEE), BD80+SVO10+DEE10, BD60+SVO35+DEE5, and BD60+SVO30+DEE10 (consisting of 60% biodiesel, 30% SVO, and 10% DEE) are tested and compared these blends with conventional biodiesel and Straight Vegetable Oil blends (BD80+20% SVO and BD60+40%SVO). The inclusion of DEE as an additive had a noticeable impact on engine performance. It significantly improved brake power, reduced Brake-Specific Fuel Consumption (BSFC), lowered Brake Specific Energy Consumption (BSEC), and increased Brake Thermal Efficiency (BTE). Additionally, all the blends containing DEE as an additive demonstrated decreased emissions of Nitrogen Oxides (NOx) and Carbon Monoxide (CO), with a slight increase in Hydrocarbon (HC) emissions. This research highlights the comparative suitability of DEE as an additive for enhancing the suitability of biodiesel-SVO blends as a fuel source for diesel engines.

The present communication is dedicated for understanding the control of Lorentz force, Soret, Dufour effect and body force on the convection-free flow of Casson fluid on heat and mass transfer due to a stretching cylinder. For the considered two-dimensional physical configuration, a non-linear partial differential equation which are coupled are derived as a governing equation to study the behaviour of concentration, temperature and velocity which in turn modified to differential equations which are ordinary and non-linear by employing a suitable similarity transformation. A well-known shooting technique is employed to understand the characteristic variations of the fluid flow with the influence of some of the non-dimensional parameters viz., Schmidt’s, Reynolds number, Soret and Dufour parameters, Hartmann number, Prandtl number. These parameters take a vital role in controlling fluid flow, heat and mass transfer in various real problem applications. The present results are contrast with the results of earlier study as a particular case and good agreement is found.

Using 3D transmission in a definite cavity with anisotropic and isotropic permeable media rotating at a fixed rotational velocity, the Rayleigh-Benard issue for a viscous, unstable, laminar, incompressible fluid heated from below a horizontal layer is extended in this paper's research. Seven controlling PDEs from the given physical configuration are similarly transformed to produce a system of non-dimensional ODEs. The Rayleigh, Taylor, and Prandtl numbers are examined for their impacts on temperature gradient and velocity in both isotropic and anisotropic conditions using the Fourier series approach. It has been discussed and determined that the results of the stream function and isotherms on a variety of factors are good.

The present work investigates the effect of 1-4 dioxane (10 ml) as additive to the diesel and blend of canola biodiesel (CABD20) on the performance of a diesel engine. The physiochemical properties of diesel, CABD20, diesel+1-4 dioxane and CABD20+1-4 dioxane fuels were measured and improved fuel properties were identified with the additive based fuels. From the experimental results, BTE was enhanced (by 1.9-2.2%) with additive based fuel over both the diesel and CABD20 fuels. The presence of HA, CO and smoke emissions were decreased in the exhaust emissions for CABD20 fuel with a marginal increment of NOx emissions. Furthermore, adding 1-4 dioxane to diesel and CABD20 fuel significantly reduced the exhaust emissions. From the observations, it is concluded that better engine performance can be obtained with the use of additives in the diesel and the blend of biodiesel.

Published: April 2024

In the course of grinding, conventional grinding fluid is frequently utilised, which leads to excessive consumption and negative environmental effects. MQL, or minimum quantity lubrication, is a possible replacement for traditional dry and fluid coolant application. It is well known that the MQL grinding process's effectiveness depends on the lubricating and cooling capabilities of fluid. A water-based Al2O3 nanofluid was used in this work to grind materials due to its outstanding convective heat transfer and thermal conductivity qualities. Hardened steel's grinding properties are examined and contrasted with those of MQL grinding done in wet, dry, and pure water. Al2O3 nanofluid MQL grinding using water dramatically lower the grinding temperatures, minimise grinding forces, and enhance the ground surface finish.

Published: April 2024

The aim of this project is to investigate the effects of surface structuring on brazed joints made of steel and tungsten carbide as well as how these effects affect the joints' mechanical characteristics. The industry uses brazing as a common connecting method, although brazing is known to produce considerable residual strains because of cooling thermal gradients. The strength, longevity, and fatigue resistance of the brazed joint can be impacted by the existence of residual stress, which might be crucial for applications in aerospace and automotive. The impact of several brazing parameters on the development of residual stress will be examined in this study, including temperature, heating rate, cooling rate, and material choice. To describe the residual stress state and assess the mechanical characteristics of the joint, experimental methods such X-ray diffraction and Shear Strength test will be used. The results of this project can be applied to numerous sectors to optimize the brazing procedure and enhance the performance and dependability of brazed components.

Человеческий фактор оказывает существенное влияние на результаты деятельность любого экономического субъекта, поэтому человеческий капитал, с точки зрения учета и интегрированной отчетности, представляет собой актив экономического субъекта, который подлежит оценке и отражению в отчетности. С одной стороны, формирование данного актива сопряжено с расходами, с другой стороны, его использование, так же приводит к расходам, которые оказывают существенное влияние на себестоимость продукции, работ, услуг. Поэтому, для повышения эффективности информационного обеспечения управления, необходимо решить ряд задач в рамках управленческого учета расходов на персонал. Исходя из модульного принципа построения программных систем управления бизнесом, в статье рассматривается организационно-методические рекомендации создания модуля управленческого учета производственного предприятия, направленные на решение важных задач управления расходами на персонал в динамично развивающихся условиях рыночной среды. Представленные рекомендации формализованы в 6 последовательных этапов, каждый из которых охарактеризован. Особое внимание уделено классификации расходов на персонал, которая является основной для построения двухуровневого аналитического учета. Отдельно рассматриваются критерии определения индивидуальных и общих результатов труда производственного и непроизводственного персонала. Оценка описанных критериев осуществляется с использованием бальной шкалы, которые переводятся в стоимостные показатели при формировании стимулирующих выплат. Сочетание материального и нематериального стимулирования позволяет мотивировать сотрудников к улучшению результатов. Систематизированный сбор, агрегирование и анализ данных в управленческом учете позволяют выявить неэффективные затраты, разработать стратегии для их снижения, поднять на более высокий уровень управление трудовыми ресурсами, что будет способствовать развитию и успеху экономического субъекта в современной бизнес-среде.
