The article presents the results of a study aimed at developing and optimizing a process for obtaining dry dietary fiber concentrate from wheat bran for use in the production of curd products. The main objective of the study was to create a method for obtaining dietary fiber that can improve the functional and quality characteristics of curd products, improving their texture, stability and nutritional value. The study covered a theoretical comparison of various methods for isolating dietary fiber, including acid and enzymatic approaches. It was found that the enzymatic method has a number of advantages, such as preserving the functional properties of fibers, environmental friendliness and higher efficiency. Optimization of the drying process showed that a temperature of 55-60 °C and a duration of no more than 10 hours are the most suitable for obtaining a dietary fiber concentrate with high water-holding capacity.The inclusion of 7% dry dietary fiber concentrate in curd products provides an optimal improvement in texture and organoleptic characteristics without deteriorating their taste. The study confirms the potential of using the obtained dry concentrate of dietary fiber to improve the functional and quality characteristics of curd products, which opens up new opportunities for their use in the food industry and increasing the nutritional value of dairy products.

Published: November 2024

In this study, cultures of lactic acid bacteria (3M, 3K, 7K, 9K, 10K and 11K) isolated from mare's milk and koumiss were examined in order to assess their resistance to various antibiotics. Discs impregnated with gentamicin (120 mcg), azithromycin (15 mcg), ceftriaxone (30 mcg), cefuroxime (30 mcg) and chloramphenicol (30 mcg) were used.The data obtained showed that strains 3K, 10K and 11K demonstrated the greatest resistance to gentamicin, similarly, strains 10K and 11K showed high resistance to azithromycin. For ceftriaxone and cefuroxime, strains 11K and 10K demonstrated the greatest resistance. Strains 11K and 10K were the most resistant to chloramphenicol, while strain 3K was the most sensitive. In general, strains 3K and 3M showed the least resistance to most antibiotics, especially ceftriaxone and cefuroxime, which indicates their high sensitivity to these drugs. In contrast, strains 10K and 11K demonstrated the greatest resistance, showing minimal suppression zones for most of the antibiotics studied.The obtained data can be used to develop and optimize probiotic drugs that take into account the resistance of lactic acid bacteria to antibiotics. This will increase the effectiveness of the use of probiotics in various foods and medicines, contributing to the maintenance of healthy intestinal microflora and strengthening the immune system.

This study investigates the impact of flue gas recirculation on key parameters of the fuel combustion process, such as heat release and adiabatic combustion temperature. Based on the mathematical processing of experimental data, equations were obtained that reflect the dependence of useful heat release and adiabatic combustion temperature on the gas recirculation coefficient. According to the results of the study, the useful heat release in the furnace increases proportionally with the growth of the recirculation coefficient. This indicates that an increase in the level of recirculation contributes to an increase in combustion thermal efficiency, improving heat exchange processes within the furnace. A similar trend is observed for the adiabatic combustion temperature. It was found that the adiabatic combustion temperature also increases with an increase in the recirculation coefficient, which indicates the significant influence of recirculation on raising the temperature parameters of the combustion process. The rise in combustion temperature is associated with improved fuel combustion and more complete utilization of its energy potential. This, in turn, can contribute to a reduction in emissions of harmful substances such as nitrogen oxides and carbon, which is an important factor for environmental safety.Thus, the results of the study demonstrate that flue gas recirculation has a significant impact on heat exchange processes and combustion temperature. This makes recirculation an effective tool for increasing thermal efficiency and reducing the environmental impact. The application of this method in modern energy systems not only improves production performance but also ensures compliance with environmental requirements. The study results confirm the feasibility of implementing flue gas recirculation to enhance overall efficiency and environmental safety in energy installations.

A first approximation of the firm-level relationship between profit margins and business investment in the Spanish economy
Authors: Puente Díaz Sergio , Mulino Ríos Maristela 
Published: November 2024

RationaleBusiness investment and profit margins both declined in 2020, but have been recovering since. Statistical analysis of firm-level data can be used to estimate the relationship between these two variables in the Spanish economy in recent years.Takeaways•After a decline in 2020, profit margins in Spain have been rising. This increase has been concentrated among firms that had lower profit margins in 2019. Conversely, firms that had higher margins before the pandemic have, overall, seen profit margins follow a downward trajectory.•The relationship between profit margins and business investment, calculated drawing on granular firm-level data, takes the form of an inverted-U curve: it is positive for profit margins below a certain threshold, but turns negative above that threshold.•In the Spanish economy, most firms stand in the section of the curve where the profit margin-investment relationship is positive. Firms in the section where the relationship is negative tend to be smaller, younger and more productive.

Второй марксизм: история сборника «Проблемы истории докапиталистических обществ» в письмах и документах
Authors: С. Алымов 
Published: November 2024

В статье рассматривается история сборника «Проблемы истории докапиталистических обществ», который задумывался как серия, однако был опубликован только один выпуск. Автор показывает, как в связи с публикацией этого сборника вокруг его главного редактора Л.В. Даниловой сложилась сеть неформальных контактов и переписки, сплотившая ученых разных специальностей, интересовавшихся первобытностью. Делается вывод о том, что эта группа является примером «второго марксизма» в СССР, то есть группы гуманитариевшестидесятников, стремившихся переосмыслить марксистское понимание истории при помощи критического прочтения трудов Маркса и Энгельса, новых данных науки и ревизии сталинской версии исторического материализма.
The article examines the history of the edited volume “Problems of the History of Pre-Capitalist Societies”, which was conceived as a series, but only one issue was published. The author shows that in connection with the publication of this volume a circle around its editor-in-chief, Luidmila V. Danilova, developed a network of informal contacts and correspondence that brought together scholars of several disciplines interested in the theoretical constructions around the notion of “primitive society”. The author concludes that this group is an example of the “Second Marxism” in the USSR, i.e. a group of scholars and “people of the 60s” who sought to rethink the Marxist understanding of history through a critical reading of the works of Marx and Engels, new scientific data, and a revision of the Stalinist version of historical materialism.

Authors: Newland Barbara , Hanson Janet , Johnson Martina 
Published: November 2024

The introduction of Personal Development Planning (PDP) has been a major policy initiative for UK HE. The HE Progress File consists of two elements, the Transcript Record of formal qualifications and the Personal Development Plan, which includes both the processes that are involved in supporting the student in undertaking PDP and also the evidence base of student achievements. In response to the policies many electronic PDP and e-portfolio tools have been developed, both commercially and through nationally funded agencies. This paper considers the issues identified by the PDP4Life regional e-learning project relating to the transfer between institutions of learner records arising from e-PDP outputs and achievements. In particular it focuses on issues that occur in support of employability in the creative industries.
The Learner's Voice

Published: November 2024

This paper outlines work in progress on a national JISC research project on the learner experience of e-learning. The project is named LEX, a contraction of the long name but also a reference to the importance of using the learner's own words in the analysis. The project covers a wide range of post-16 learners including adult, community and work-based learners as well as FE and HE learners, distributed widely across the UK. We describe the development, evolution and implementation of the research methodology, and how we tackled practical problems of reaching such a diverse learner group. We go on to outline three case studies which illustrate how learners describe their approaches to fitting learning into their lives, to accomplishing e-learning tasks, their strategies to overcome problems, and their expectations and experiences of e-learning across a range of educational contexts and technology use. The paper does not present findings or research outcomes, however tentative, since we are only at the start of the analytical phase. The case studies do however indicate some of the issues that learners have raised in the research.

The worth of a firm is a crucial element. This is because it can reflect how well a corporation performs. Company performance consists of various components, one of which is financial performance. Investors often use financial performance as a parameter when making stock investment decisions. This study aimed to prove whether financial performance affects the value of companies in the property and real estate sector listed on the Indonesia Stock Exchange from 2022-2023. The population observed in this study is all companies in the property and real estate sector listed on the Indonesia stock exchange for 2022-2023. The sample collection uses certain criteria better known as purposive sampling, so there are 60 sample companies, and the total research data is 120. The analysis method is done by applying the classical assumption test and multiple linear analysis, with a decision stating that the data is normally distributed and free from all symptoms of basic assumptions in regression analysis. Hypothesis testing reveals that partial results of liquidity, profitability, and activity variables can affect firm value, while solvency variables cannot affect firm value. For simultaneous testing, liquidity, solvency, profitability, and activity variables can affect firm value. The outcomes of this study are expected to participate in the development of financial theory which will certainly help enrich the understanding of how firm financial elements influence value and can accommodate financial analysts in making more informed decisions.

<p>Ewes are polyoestrous seasonal animals, however in order to increase their fertility, progesterone derivatives are used by means of impregnated sponges with 20 mg of fluorogestone acetate (FGA). Nevertheless, the use of sponges with FGA generates vaginitis, erythema and interferes with fertility. This paper studies the effect of FGA and sponge over the microbiota vaginal in ewes anestrous. To obtain experimental samples, fifteen ewes anestrous were used. Five ewes were used as control group. Ten ewes anestrous were used and data were collected before, withdrawal and 56 h after withdrawal of sponges with and without FGA, in order to quantify, identify and evaluate changes in the vaginal bacterial microbiota. In the normal microbiota were found <em>Escherichia</em> and <em>Klebsiella</em> strains; however, after removal of the devices, were found enteropathogenic coliform bacterias and some opportunistic as <em>Shigella, Enterobacter, Citrobacter, E. coli, Pseudomonas </em>and<em> Acinetobacter</em>. Also found that the device without FGA, induces a change in the vaginal microbiota, thus, causes vaginitis. <em>In vitro</em> sensitivity tests were performed on the strains identified using twelve different antibiotics; the results showed a higher sensibility to enoxacin, then to the trimethoprim-sulfamethoxazole, ceftriaxone, chloramphenicol and ampicillin. Antibiotics use is necessary to prevent the vaginitis in ewes with dispositive. In conclusion, the intravaginal sponges promote of the vagina inflammation and produce coliform bacteria in vagina. </p>

<p>The aim of this work was to assess the effect of two arbuscular mycorrhizal fungi (AMF) inoculants in the development of avocado rootstocks. Seeds of Mexican landrace avocado (<em>Persea americana</em> Mill. var. <em>drymifolia</em>) were used, with two commercial inoculants: T1 containing <em>Glomus fasciculatum, G. constrictum, G. tortuosum, G. geosporum,</em>and<em> Acaulospora scrobiculata, </em>and T2, containing <em>G. mosseae </em>and<em> G. cubense</em>. The plants inoculated with AMF showed more rapid growth than the no inoculant control as measured by plant height (50% and 54%), stem diameter (35% and 36%), leaf number (48% and 37%) and length (31% and 40%), and root fresh weight (85% and 59%); however, no significant differences were observed between T1 and T2. The chlorophyll concentration in the leaves from T1 was 16.4% and T2 was 19% higher than the control suggesting a higher photosynthetic capacity in T1 and T2. Finally the shoot/root ratio, as indicator of the potential development of plantations, was 79% and 50% higher in mycorrhizal plants than in the control. In conclusion both T1 and T2 inoculants improved growth rate and vigor of avocado nursery rootstocks producing higher quality plants.</p>
SOIL AGGREGATE FRACTIONS AND ORGANIC CARBON POOLS AS INFLUENCED BY TREE DIVERSITY IN FOREST RESERVE OF SEMI ARID NIGERIA

Published: November 2024

<p>The ability of trees to sequester carbon vary from species to species, this study therefore evaluates the influence of seven tree species (<em>Acacia senegal, Azadirachta indica, Eucalyptus camadulensis,</em> <em>Khaya senegalensis, </em> <em>Prosopis africana, </em> <em>Tamarindus indica </em>and <em>Tectona grandis</em>) on soil aggregate fractions and various pools of carbon in soil at three soil depth (0-5, 5-15 and 15-25cm). Results revealed that most soil quality enhancing properties concentrated more at the soil surface (0-5cm) relative to other depths. Soil planted to <em>T. indica</em> stood out in possessing high proportion of large and small macro aggregates, mean weight diameter (MWD) and least proportion of silt plus clay particles. High proportion of fine particulate organic carbon, particulate organic carbon, silt plus clay associated organic carbon and non hydrolysable organic carbons were attributed to soil under <em>T. indica.</em> <em>Tamarindus indica </em> might be a better choice of the seven tree species in mitigating green house effects by sequestering atmospheric carbon and improving soil aggregate stability.</p>

<p>Plant species that successfully establish in environments of recent formation, such as barrier islands, exhibit life history traits that allow them to efficiently capture nutrients and water, such ability may be largely due to interactions these plants establish with mutualistic arbuscular mycorrhizal fungi (AMF). The goal of this work was to characterize plant community present at two sites, a barrier island and a coastal dune system; the influence of marine proximity against the lagoon proximity and to relate aspects of these plant communities to soil fertility and AMF presence in roots y la rhizosphere. The study was conducted at “La Carbonera” in Chuburná, Yucatan, Mexico. At each site we established transects, where we placed three 5 x 5-m plots. Within each plot we surveyed vegetation (recording present species and plant cover), collected root samples to assess AMF colonization, and collected soil samples for nutrient analyses and quantification of AMF spores in rhizosphere. We found a total of 36 plant species from 28 families, with herbaceous life form being the most common. All plant species recorded were colonized by AMF. Nonetheless, AMF spores were scarce in soil, which may be due to immediate AMF root colonization of host plants trigger by low phosphorus and nitrogen availability in soil. Our results suggest that the AMF propagules may colonize the roots since the first stages of plant establishment on sand dunes. <strong></strong></p>
