Authors: Kalyuzhny Alexey Igorevich , Romanenko Nikolay Gennadievich
Published: December 2024

The possibilities of improving energy efficiency in the shipbuilding and ship repair industry are being considered. Energy efficiency plays a key role in modern industry, especially in industries with high energy consumption, such as shipbuilding and ship repair. In the Astrakhan region, with a significant amount of available water resources, there are many enterprises in this industry. An overview of the industry in the region is presented, an analysis of the structure and dynamics of electricity consumption at enterprises in this industry is carried out, the identification of the main consumers of electricity and the most energy-consuming processes are identified. Based on these data, measures are proposed to optimize energy consumption. The existing technologies and methods aimed at reducing energy consumption and increasing energy efficiency in the shipbuilding and ship repair industry are analyzed. Both technical and organizational measures are considered, such as the introduction of energy-saving equipment, optimization of production processes and the introduction of energy monitoring and management systems. Recommendations on improving the energy efficiency of enterprises in the shipbuilding and ship repair industry will reduce energy costs, improve the environmental sustainability of production and increase the competitiveness of companies in a market economy. The results obtained can be used by the management of enterprises, energy management specialists and government agencies to develop strategies to reduce energy consumption and improve energy efficiency in this industry. An integrated approach will be useful to enterprises in the shipbuilding and ship repair industry for the efficient use of available resources, reducing costs and minimizing negative effects on the environment, which in the long term will contribute to increasing competitiveness and sustainability.

Published: December 2024

A method is proposed to solve the problems that arise when analyzing information obtained from various sources, it is necessary to combine it in a complex of coordinated stochastic models. For most processes of mechanical destruction of machine parts, such as wear, fatigue volumetric or surface destruction, corrosion, etc., the monotony of the implementation of degradation processes leading to failures is characteristic. The scheme of resource allocation formation is given, which corresponds to the main types of mechanical failures occurring in the elements of ship mechanisms. The diagram illustrates a fairly general case when, with an increase in the operating time of an element, its resistance to destruction decreases monotonously, and the damage parameter also increases monotonously. Based on the use of generalized distributions, it is possible to obtain several variants of complexes of mechanical reliability models in which the resource allocation has a fairly simple analytical form. When modeling degradation processes, the DM distribution can be obtained as a special case of distributions and without using the Markov model of random processes. Only the mixing condition of the process implementations is essential. Obtaining various types of operating time distributions before the parameter reaches a fixed level using the obtained dependencies is not associated with any assumptions about the nature of individual implementations of the degradation process, except for their monotony. From the point of view of practical application, the distribution under consideration, obtained on the basis of Weibull’s law, has the advantage of universality, since, unlike the normal law, it can also be used for values of the coefficient of variation significantly exceeding 0.3.

Published: December 2024

The results of laboratory studies on the non-dismountable assessment of the technical condition of a model torsional vibration damper conducted at the MTS testing center of the Astrakhan State Technical University are presented. The relevance lies in the practical application of the obtained research results for a non-dismountable assessment of the technical condition of silicone dampers of marine diesel engines and improving the effectiveness of the existing methodology. The assessment is proposed to be carried out using an in-depth analysis of the torsional oscillation function using wavelet analysis and window Fourier transform methods for dynamic modes of operation of a marine power plant with a rapid change in the rotational speed of the shaft line – start, set the rotational speed and stop. These modes can be dangerous for marine propulsion systems, which is confirmed by a number of facts of shaft destruction and loss of propellers during start-up and reverse of the main power plant. As criteria for evaluating the technical condition of the damper are adopted both traditional ones (the magnitude of stresses in the shafts, the amplitude and frequency of torsional vibrations) and the author's ones (the characteristics of the waveform analysis and windowed Fourier transform methods of the torsional vibration function) as well as the magnitude of vibration along three measuring axes. The data were obtained as a result of the use of the author's experimental samples of the torsional vibration monitoring system and a measuring device based on accelerometers in research. As a result of the study, the dependence of the voltage changes in the shafts, the frequency of vibrations, vibration and the characteristics of the waveform of the wavelet analysis of the Morlet function and windowed Fourier transform diagrams of the torsional vibration function on three simulated situations of the technical condition of the silicone damper – during silicone leakage, flywheel mass sticking and normal operation.

Published: December 2024

The development of a system for supplying working fluid (engine oil) to ensure the similarity of operating conditions of a model of a spring damper for torsional vibrations of a marine diesel engine during experiments at the laboratory stand of the Marine Technology Service testing center of the Astrakhan State Technical University is considered. Currently, spring (mechanical) torsional vibration dampers of marine diesel engines are produced only by foreign companies. A lot of scientific work is required for their design, manufacture and operation, including physical modeling of the design and operating conditions of laboratory versions of dampers. The application of the physical modeling method makes it possible to reduce the cost of testing real spring dampers of torsional vibrations of marine diesel engines, determine the main dependencies of damping parameters on various operating conditions, develop basic criteria for non-selective diagnostics to assess its technical condition and predict the development of emergency situations. The modernization of the laboratory stand is necessary for the operation of model spring dampers with a developed system for supplying working fluid. The spread of spring dampers is justified by the design features of such devices, which allows the use of both elastic and hydraulic damping. For the development of the working fluid supply system, calculations were made of the stiffness and thermal power of the model spring damper, taking into account the design of the laboratory stand.

Published: December 2024

The problem of determining the ability of a liquid to penetrate into the structure of a composite material prepared using reinforcing glass fabrics and a polyester binder is solved. The determination of the ability of water to penetrate into the structure of samples cut from a common plate of polymer composite materials (PCM) is carried out by determining the change in weight of samples before and after their immersion in a container with a liquid medium (water) for a certain period of time. The ability of water penetration into the composition of this material has been established depending on its structure, that is, on the location of the reinforcing material. The mechanical properties (tensile, compressive and bending strength) of a composite material after its removal from a liquid container are presented. The problem of the possibility of the effect of processing the ends of cut test samples with polyester resin on the ability of liquid penetration into the composition of a PCM is solved. For this purpose, samples cut from a common plate were immersed in containers with water, while the ends of one batch of samples were coated with polyester resin, and the other batch was uncoated. The influence of the presence of samples in a liquid medium (water) with a certain ratio of layers of reinforcing material (glass wool and roving fiberglass) on their mechanical characteristics during bending, stretching and compression has been established. The test results of the samples are presented, which showed a direct dependence of the tensile strength and destructive force on the number of roving layers in the PCM structure of the samples whose edges were treated with polyester resin. During the experiments, the ability of liquid penetration into the structure of composite materials and changes in mechanical properties as a result of immersion of these materials in a liquid medium were determined. The obtained results of experimental tests of samples made of PCM with various reinforcement schemes will justify their widespread use in ship hull structures, in particular, as a material for the manufacture of ship tanks.

Authors: Ilyin Roman Albertovich , Shishkin Nickolai Dmitrievich
Published: December 2024

Marine infrastructure facilities include various structures and structures that are necessary to ensure the functioning of maritime transport and other types of mandatory operations in the water space: passenger and cargo terminals, transshipment complexes, warehouses, infrastructure facilities for maintaining ships in working condition, heat supply systems, gas supply, water supply and power supply systems, necessary for the continuous provision of various processes of the port's vital activity. The issue of operation of the developed experimental design of a wind power plant (wind turbine) that recycles secondary energy resources of power facilities of marine infrastructure, when it is placed on the chimneys of boiler installations of port facilities, is considered. An experimental wind turbine is being developed that will use the secondary energy resources of the enterprise. Such a resource in port facilities may be the exhaust gases of a boiler house or a mini-CHP based on internal combustion engines, etc., the heat of which will be utilized in the proposed wind turbine to generate electricity to cover part of the needs of the energy facility. The introduction of wind power plants in port facilities represents an important strategic initiative with many advantages: energy independence and reduction of energy supply costs; elimination of sharp fluctuations in electricity prices, which may be caused by changes in prices for traditional energy carriers; reduction of greenhouse gas emissions; improvement of ports' public image, stimulation of economic development of the region. It is noted that some governments and international organizations offer financial support and incentive measures for projects on the introduction of renewable energy sources; wind turbines can act as a backup energy source, providing higher reliability of energy supply in case of disruptions in the main network, etc. All these measures for placing wind turbines on the chimneys of marine infrastructure power plants make it possible to increase the efficiency of energy generation from a generating plant in the port.
Growth of perch Perca fluviatilis L., 1758 (Percidae) in the Kazakh part of the Ishim basin

Published: December 2024

The growth of Eurasian perch in water bodies within the Ishim River system in the Republic of Kazakhstan has been investigated. Data from 29 samples from various water bodies of the Ishim watershed and some adjacent watersheds are presented. The most extensive age series were found in specimens from Lake Lobanovo (National Park “Kokshetau”) – up to sixteen years (15+). River populations had a shorter lifespan. Comparison of growth rate patterns indicates the presence of two conditional “units”: the first includes the majority of lake populations, while the second includes Karatomarskoe Reservoir and Lake Lobanovo. Some samples are located outside of these groupings. The examined chronological samples show significant differences in growth for some. This is typical for Lake Karakol and, partialy, – the Ishimskoe Reservoir, where positive hydrological changes occurred between perch catches years, resulting in increased growth rates. These samples exhibit a low level of correlation in growth indicators between adjacent ages, indicating disruption in growth rate “canalization” and the acquisition of opportunities for individuals in a renewed unbalanced habitat environment. In relatively stable conditions of most other water bodies, the correlation level of these data indicators is high for the majority of comparison pairs. When comparing Ishim populations with previously published data on the Nura and Sarysu river watersheds re-garding growth rates, one can empirically conclude about the more successful growth of perch in the Nura-Sarysu watershed. However, it should be noted that mainly water bodies without commercial fishing and with developed recreational fishing were studied in the Ishim watershed. In contrast, water bodies with predominant commercial fishing were surveyed in the Nura-Sarysu system. The different impacts of these types of fishing may determine both the growth rates and the lifespan of perch.

Published: December 2024

In modern conditions due to the intense anthropogenic impact on the ecosystem, and accordingly on the habitats of valuable fish species, there is a landslide reduction in spawning populations of thorn in the Ili-Balkhash basin. The issue of preserving this species is discussed through the formation of repair and breeding herds from “wild” individuals, domestication in controlled conditions of fish farms. Only under controlled conditions are there opportunities for the formation of productive herds of endangered fish species. The production facilities of Halyk Balyk LLP were used to carry out work on the reproduction of young thorns and the formation of repair and brood stock of thorns. Throughout the entire period of thorn cultivation, direct-flow water supply from an artesian well was used in the pools of Nalyk Balyk LLP. The water temperature in the pools ranged from 15.0 to 15.50 °C. To increase the immune status in order to prevent stress, courses of vitamin C, B vitamins, and viusid - vet feed additives were regularly administered as needed. The use of such a feeding scheme allows to increase the growth rate of fish, increases the survival rate of fish and improves their physiological condition, fish become more resilient. The adaptation of “wild” individuals of the thorn takes place in a shorter time. Based on the determination of the growth and dynamics of the mass of adaptable individuals, it was found that the habituation to new conditions and artificial feeds is slow, only in the second month the fish begins to eat fruitfully. The survival rates of the domesticated thorn for the entire growing period were 100%.

Published: December 2024

The effect of grape seed extract (GSE), containing 95% proanthocyanidins, on the physiological state of sterlet grown in conditions of closed water supply system is investigated. Additionally, the changes in the antioxidant activity of compound feed with the introduction of GSE (in dry and water-dissolved) after 1, 3 and 24 hours are analyzed. It is established that the greatest total amount of water-soluble antioxidants (TAWSA) is observed in the Russian compound feed with introduction of water solution of GSE (95% proanthocyanidins). The introduction of 50 mg of GSE per 1 kg of compound feed for 63 days promotes changes in the biochemical parameters of blood and organs of the experimental sterlet group. The total amount of water-soluble antioxidants in the liver increases by 25% (p < 0.05) compared to the control group. There is a tendency to increase the level of total protein (0.05 ≤ p ≤ 0.1), increase in albumin level by 36.47% (p ≤ 0.01) and the alkaline phosphatase enzyme activity by 25.45% (p ≤ 0.01) in serum. There is also a significant decrease in glucose levels in the experimental group of 60.22% (p < 0.01). There are no differences in the chemical and mineral composition of meat (p ≥ 0.1). It is assumed that in sterlet of the experimental group metabolism is intensified and oxidative processes in the liver are reduced. It is proposed to use GSE containing 95% proanthocyanidins in a dosage of 50 mg/kg as an additive in compound feed for juvenile sterlet to prevent oxidative stress and stimulate metabolic processes in the body.

Authors:   Tyumen Industrial University, Kurushina Elena V. , Sechnaya Кristina А. ,   Tyumen Industrial University
Published: December 2024

The article examines the positive and negative impact of external environmental factors on the Russian oil and gas business in Russia. PESTLE-analysis by the expert method was carried out, on the basis of which the most significant risks for the gas business – reduction of sales in the European market and ban on oil and gas equipment supplies – were identified using quantitative assessments. The impact of sanctions on the operational results of PJSC “Gazprom” was investigated, revealing a substantial decline in revenue and profit from sales, primarily due to the imposition of anti-Russian restrictive measures. These negative trends were partially mitigated by an increase in gas supplies to China and the Commonwealth of Independent States (CIS), as well as growing domestic market demands, which altered the geographical structure of sales volumes. Within the framework of a long-term development program, the article substantiates the potential for diversifying gas export supplies to Asia-Pacific countries and identifies revenue growth reserves through the gasification of Russian regions using statistical methods. Additionally, the advantages of redirecting supplies of key oil and gas equipment to Chinese manufacturers were identified, which could significantly reduce both the delivery time and costs by up to 40 %.

Published: December 2024

The article provides a comparative analysis of economic integration processes in Russia and the world. The analysis encompasses statistical information reflecting the shares of BRICS+ and G7 countries in the world production, consumption, and gross domestic product (GDP) measured by purchasing power parity. Key reasons motivating states within the international community to unite for the purposes of international trade, capital movement, labor migration, and other forms of economic activity are identified, particularly in the context of establishing protective economic mechanisms based on the organization of a multipolar world. The article also highlights the primary factors contributing to the degradation of economic integration processes within the European Union. It concludes that modern economic integration processes create a broad spectrum of challenges for the development of both the Russian Federation and other countries within the global community. These challenges are attributed to the outcomes of both material and non-material production within economic unions and associations, the turbulence of socio-economic processes across various regions, and the volatility of global markets. Furthermore, the transformation of international economic security emerges as a driving force behind integration processes and a guarantor of balanced sustainable development for the world community in the context of multipolarity.
Modification of the Method of Financial Law in Relation to the Modification of Its System Under Modern Conditions: Is It Possible?
Authors:   Voronezh Institute of the Federal Penitentiary Service, Peshkova (Belogortseva) Christina V.
Published: December 2024

This work aims to review the main trends in the modification of the system of financial law under modern conditions and, consequently, the method of financial-legal regulation. Historical and modern approaches to the structuring of financial law are taken into account, which influence the specifics of the method of financial law. The author emphasizes the impact of digitalization on the modification of the subject matter, system, and method of financial law. The author comes to the conclusion that it is not necessary to artificially increase the legal arrays of norms to branches of law, sub-sectors (in relation to this work – financial law) due only to the excess volume of legal regulation in a specific area (in the field of finance). However, financial law must respond in a timely manner to the processes taking place in society by expanding the subject of regulation, as well as the limits of financial management, which means deepening the imperative method of regulation. It is the imperative method in modern crisis conditions that will ensure legality and law and order in the field of finance, and not dispositivity in the implementation of financial relations. Nevertheless, the imperative method of regulating financial law must be economically justified, which has implications for the construction of the system of modern financial law. Thus, while the system of financial law evolves under the influence of external conditions, it does not lead to fundamental changes in the method of financial-legal regulation.

Published: December 2024

Currently, against the background of the desire of individual political actors to falsify history, the study of the phenomenon of historical memory in the political dimension is of particular importance. The article analyzes muhajirism as a factor of historical memory influencing the current state of Russian society. The features of the reflection of the problem of muhajirism in the scientific literature of various historical periods are considered. A content analysis of social network materials (platforms) was conducted, aimed at identifying the attitude of Russian-speaking users to the problem of muhajirism. The main categories of comments reflecting user reactions to the topic of the resettlement of the highlanders are identified. The content analysis showed that the problem of muhajirism fuels nationalistic sentiments of certain categories of citizens, therefore, it can be used as an instrument of pressure on Russian society in order to disunite it. It is noted that there is a demand in society for reliable and accessible information on the topic of muhajirism, in connection with which such studies are of particular relevance.

Sustentabilidad hídrica de la Ciudad de México: un real motivo para planear
Authors: Muñoz Villarreal Carlos
Published: December 2024

En el análisis que aquí se presenta, se entretejen categorías de los modelos de gestión hídrica y el referente de sustentabilidad, con insumos de carácter socio-político sobre la planeación en el contexto urbano, para establecer una argumentación de carácter híbrido sobre el papel de la planeación en torno a la gestión del agua en la Ciudad de México. Se establece que la compleja y creciente problemática hídrica de la Ciudad impone la necesidad de considerar objetivos y estrategias que atiendan las necesidades sociales en un marco de sustentabilidad hídrica de mediano plazo. Esta se presenta, entonces, como una de las expresiones más claras de la necesidad de una auténtica planeación urbana, que se ha vuelto esquiva en la Ciudad. A partir de una revisión de la problemática en torno al agua y del modelo de gestión hídrica, que se ha mantenido durante largo tiempo, se argumenta, por una parte, la necesidad de reorientar este último y de definir los grandes objetivos y metas a partir de las necesidades sociales y económicas fundamentales y de criterios de índole hidro-ecológica. Se plantea que, a partir de esta definición, a la cual pueden contribuir elementos de diagnóstico de carácter técnico, se puede entonces construir un consenso social básico, el cual permita instrumentar estrategias, modalidades alternativas de gestión e inversiones que tienen importantes implicaciones sociales y económicas (incluidas las de carácter redistributivo), deben enfrentar inercias y pueden generar fuertes resistencias. En el proceso de ofrecer nuevas respuestas para la sustentabilidad hídrica, a su vez, se vuelven importantes la consideración de la diversidad de la Ciudad y su entorno inmediato, la suma de recursos y de distintas modalidades organizativo-institucionales, así como la operación de esquemas menos centralizados de gestión hídrica. Todo esto brinda también argumentos para una auténtica planeación de carácter participativo, con el involucramiento de diferentes actores y que sea ampliamente socializado.
El papel de la política económica urbana en el desarrollo de la ciudad y la realización de los derechos humanos
Authors: Ejea Mendoza Guillermo
Published: December 2024

Este texto propone reconceptualizar la política económica a nivel urbano para convertirla en un medio de realización del desarrollo y los derechos humanos en la Ciudad de México. Se explica por qué el desarrollo de la ciudad y el cumplimiento del derecho a la ciudad son dos caras del mismo proceso, y el papel que una política económica concebida adecuadamente puede jugar en ello. Se pone de relieve el carácter capitalista no-desarrollado de la Ciudad de México y el poder del capital inmobiliario-financiero para influir en la morfología urbana no deseada, lo que debe ser tomado en cuenta por cualquier estrategia encaminada al cumplimiento a plenitud de los derechos humanos en ella, incluyendo un papel activo por parte del gobierno.

Published: December 2024

The study examines the acceptance and sustainability of vegetarian, vegan, and flexitarian diets, focusing on the health and environmental benefits of reducing animal-derived proteins. Our objective was to investigate the level of acceptance of these dietary trends across different age groups and health statuses and understand how sustainability awareness and health consciousness impact dietary decisions. We used a mixed-method approach to achieve this, conducting eight in-depth interviews and a survey with 329 participants from various demographic backgrounds. Our qualitative analysis revealed that individual and family health consciousness, along with sustainability considerations, play a significant role in dietary choices, particularly among younger generations who are more open to sustainable eating. Quantitative results show that access to information and educational resources strongly influences dietary decisions, further supporting the spread of environmentally conscious eating habits. The practical significance of our research lies in highlighting the importance of educational campaigns and public health policies that can foster broader societal acceptance of sustainable diets. Educational institutions and community organizations can help facilitate the transfer of knowledge necessary for adopting such diets. Our findings emphasize the role of targeted communication strategies in increasing awareness of the benefits of plant-based diets. Furthermore, these insights underline the potential of policy interventions to make sustainable food choices more accessible and appealing to a wider population. Future research could focus on exploring economic incentives and examining long-term health and environmental outcomes associated with these diets.

Authors: Yılmaz Yusuf , Vural Ecem , Topuz Ayhan
Published: December 2024

The aim of this study was to produce a juniper extract powder rich in some bioactive and volatile components such as phenolics, α-pinene and d-limonene with a high yield. For this purpose, the juniper extract, which can be used in various food formulations, was spray-dried under optimized conditions. In this optimization, inlet air temperature (120°C - 180°C) in the spray drying process and the carrier composition were selected as independent variables, while dependent variables included drying efficiency and the total phenolic (TPC), and α-pinene contents of the extract powder. Response surface methodology was used to maximize product yield, TPC and volatile levels, especially α-pinene. The optimum inlet air temperature and carrier ratio were 180ºC and 15 g gum Arabic (GA) per 100 mL extract, respectively. The highest powder yield (37.92%), TPC (9.91 mg GAE/g dm powder) and α-pinene content (peak area 1.3×107) were obtained under the optimum conditions while the bulk and compressed bulk densities, TPC and antioxidant activity of the extract powder were 0.39±0.01 g/cm3 and 0.51±0.02 g/cm3, 9.89±0.27 g gallic acid equivalent (GAE)/100 g (dm) and 4.12±0.14 g Trolox® equivalent antioxidant activity (TEAC)/100 g dm, respectively. The particle size of the powder produced under optimum conditions ranged from 1.09 to 22.39 µm. Fifteen volatiles in both juniper extract and the reconstituted form of the extract powder were identified, and the major components of juniper extract were d-limonene, α-pinene and γ-muurolene.

Published: December 2024

Parsnip (Pastinaca sativa L. subsp. urens) is one of the species of Pastinaca genus. This plant has been traditionally used worldwide for the treatment of various diseases and cultivated for its nutritional values. The aim of this study was to determine the antimicrobial and enzyme-inhibitory potentials of the fruits and leaves of parsnips as well as their bioactive properties such as their antioxidant activities, total phenolic and flavonoid contents in their hexane and ethanol extracts. The total phenolic and flavonoid contents were determined using Folin-Ciocalteu and aluminum chloride colorimetric methods, respectively. The antioxidant activities of extracts were determined by three methods of DPPH and ABTS radical scavenging activities and iron-chelating ability. In the leaves, the highest total phenolic content (60.94 mg GAE/g extract) was found in ethanol extracts while the highest total flavonoid content (21.47 mg RuE/g extract) was determined in hexane extracts. Ethanol extracts of leaves showed the highest radical scavenging activities in both assays of DPPH and ABTS with the IC50 values of 1039±1.35 and 150.7±0.81 µg/mL, respectively.

In recent years, there has been an increasing interest on foods that are perceived to be healthy and functional among societies. The composition of honey, which plays an important role in human nutrition, is influenced by a number of factors. The aim of this study was to analyze fifteen different honey samples according to various quality criteria and to determine their 5-hydroxymethylfurfural (HMF) and phenolic components. In this context, honey samples were obtained from five distinct geographical regions within the Erzurum city area in Türkiye. There were statistically significant (P<0.05) differences in the pH, moisture, total sugar, reducing sugar, sucrose, proline, 5-hydroxymethylfurfural (HMF) and phenolic content values among the honey samples. HMF contents of samples varied between 5.20 and 108.12 mg/kg, and their phenolic contents ranged from non-detected to 202.95 mg/kg. While the HMF contents of honey samples were in accordance with the Turkish Food Codex Honey Communiqué (Communiqué No: 2020/7), with the exception of only one sample in terms of its proline and HMF contents.
Regression Tool in MS Excel® Spreadsheets for Biological Data: R-BioXL
Authors: Öksüz Hasan Basri , Buzrul Sencer
Published: December 2024

A user-friendly MS Excel® spreadsheet as a freeware (R-BioXL) was developed to fit mathematical models to experimental data. (R-BioXL is available to everyone at https://drive.google.com/drive/folders/1GyjT3Z_CJQZu6ASb4LQBlS-ajLa_nF6X?usp=sharing) Initially, users are expected to enter their X-Y data and define their parameters of the model. Then, a model equation should also be entered again by users. Users can visualize data (scatter plot) and model fit (line plot) with the defined initial estimates of parameters on the same graph by default. Squared differences between experimental data and model estimates are calculated automatically. Users can change the initial estimates of the parameters to make the model closer to the data instantly, and Solver Add-In of Excel® should be used to minimize the sum of squared error by changing the parameter values. After the parameters are obtained, standard errors (by using “SolverAid” macro), 95 and 99% confidence intervals of the parameters, p values to determine the statistical significance of the parameters, and goodness-of-fit indices are calculated as the last step. All results can be saved on a different Excel® working page. Whole procedure takes a couple of minutes (~3 to 10 min) depending on the Excel® experience of the user. The utility, accuracy and reliability of the spreadsheet was shown by applying two-parameter (non-linear) Michealis-Menten equation for enzyme kinetics, three-parameter (linear) van Deemter equation for chromatography, and four-parameter (non-linear) modified Gompertz equation for microbial growth. In conclusion, R-BioXL can be safely and freely used to describe the experimental data with Excel® knowledge, without any skills in programming and without additional cost for other software package.
On semi-projective modular lattices

Published: December 2024

A. Haghany and M. Vedadi, as well as M. K. Patel, explored the relationship between a semi-projective and retractable module and its endomorphism ring. In this work, we study the lattice-theoretic counterparts of these results. To this end, we consider the category of linear modular lattices. Specifically, we show a relation between a retractable and semi-projective complete modular lattice and its monoid of endomorphisms.
Evaluating the feasibility of using whole blood gene expression profiles to identify novel targets in canine septic peritonitis

Published: December 2024

OBJECTIVE

To assess gene expression profiles in canine whole blood with and without septic peritonitis to assess workflow feasibility and identify potential blood biomarkers that could be further investigated in future studies.

METHODS

This study enrolled 6 dogs with cytologically confirmed septic peritonitis of any cause and 6 healthy dogs. All dogs had a CBC and biochemistry performed. The dogs with septic peritonitis also had point-of-care lactate and blood oxygen saturation measured for acute patient physiologic and laboratory evaluation score calculation. All dogs then had 2.5 mL of whole blood collected and placed into an RNA stabilization tube, which was processed using a commercial assay based on the hybridization of fluorescent probes for transcript quantification. Quality control, normalization, and data visualization were performed. Raw counts were exported, and differential expression was performed.

RESULTS

The evaluation of canine whole blood expression profiles was confirmed to be feasible. Differential expression analysis of septic and nonseptic dogs demonstrated distinct gene expression profile signatures. Five genes of interest were upregulated in septic whole blood including matrix metallopeptidase 9, IL-1 receptor type 2, proliferating cell nuclear antigen, phosphatidylinositol 3-kinase catalytic-γ, and cluster of differentiation 55.

CONCLUSIONS

The study and associated workflow were feasible and can be scaled in confirmatory studies.

CLINICAL RELEVANCE

Future studies are now proposed to further validate the increased expression of putative biomarkers in a larger cohort of canine septic peritonitis patients with more relevant comparator control cohorts.

OBJECTIVE

A comprehensive research was conducted to investigate the incidence of avian pathogenic Escherichia coli (APEC) in ostrich farms in Egypt.

METHODS

The study involved seven farms with bird ages ranging from 1 to 12 weeks and capacities of 2,000 to 5,000 birds per farm. 175 tissue specimens were collected from different organs (liver, spleen, heart, lung, kidney, intestine, and meat).

RESULTS

Clinical signs of APEC infection included diarrhea, lethargy, depression, and weight loss, with a morbidity rate of 36% and a mortality rate of 7.6%. In the current study, 52.5% of the samples have E coli. The highest prevalence was observed in the liver (10.8%), followed by the spleen and intestine (8% and 9.1%, respectively). The most common serotype identified was O27 (28%), after that O78 (20%) and O44 (12%). Histopathological examination revealed severe lesions in various organs, including the liver, kidney, heart, and intestine.

CONCLUSIONS

The study concluded the presence of APEC in different organs of ostrich in Egypt especially the liver, spleen, intestine, and breast muscle (meat) with evidence of severe pathological lesions in various organs.

CLINICAL RELEVANCE

The study highlights the significance of APEC as a main cause of morbidity and mortality in ostriches. It underscores the necessity for actual control measures to avoid spreading the disease.
On the nature of copper binding to benzene
Authors: Granatier Jaroslav , Kováčová Andrea
Published: December 2024

Adsorption of copper atom on benzene surface has been studied at the ab initio MP2 and CCSD(T) theory levels. CCSD(T)/CBS binding energies of the copper atom adsorbed on hollow, top, and bridge positions are 16.77, 19.27 and 21.08 kJ/mol, respectively. Adsorption at the bridge position represents the most stable structure of the Cu-benzene complex with charge transfer from benzene to the copper atom playing a key role.
Theoretical and experimental study of monoethanolamides and diethanolamides as potential additives to fossil diesel fuel
Authors: Kocsisová Teodora , Kováčová Andrea
Published: December 2024

In this work, theoretical and experimental study of monoethanolamides (MEAD) and diethanolamides (DEAD) is presented. The aim was to investigate the thermodynamics of addition reactions used in the synthesis of MEAD and DEAD. The reactions have exothermic character and alkyl elongation affects the reaction enthalpy of DEAD production reactions. In the experimental part, the prepared MEAD and DEAD samples were preliminary tested as a potential additive in diesel fuel. The research focused on measuring three key properties: i.e., foaming, lubricity, and cetane number. The results suggest that MEAD is a suitable additive for diesel fuel.
