Authors:   Malyishkin P.YU. Kartashevich A.N. Plotnikov S.A. Buzikov SH.V.
Published: November 2023

A study aimed at organizing the combustion process, which ensures the operation of a tractor diesel engine with external mixture formation, is relevant. The main purpose of the work is to determine the type and proportion of gas fuel added to the tractor diesel cylinders with a fresh charge, at which the mixture formation changes from internal to external. To determine the reliability of theoretical assumptions, experimental studies of a diesel engine with a dimension of 4CHN 11.0/12.5, brand D-245.5S2 were carried out on a load electric brake stand Rapido (made in Germany) brand SAK N670 with a balancing pendulum machine with a power of 250 kW, using specialized equipment for indexing. As a result, the change in mixture formation in the tractor diesel cylinders from internal to external, occurring at a constant diesel fuel injection rate, was theoretically substantiated. The type of gas fuel in the form of a propane-butane mixture with its addition to the main diesel fuel in an amount of 38 % and more by weight was determined as a gas fuel for the tractor diesel under consideration at a given load-speed mode of operation. It was experimentally established that the addition of a share of gas fuel up to 40 % led to the complete exclusion of the diffusion phase of the combustion process, which in turn indicated the transition of the operation of a diesel engine with a dimension of 4ChN 11.0 / 12.5, brand D-245.5S2 from internal mixture formation to external.

Zerumbone Molecule on Breast Cancer
Authors: Chakrabarti Somak
Published: November 2023

Cancer is a significant danger to general wellbeing universally, causing roughly ten million deaths globally in 2018. Regardless of advances in regular therapy in modalities of the malignant growth treatment, there are, as, yet, scarcely any effective therapies accessible because of the absence of selectivity, unfavourable results, toxicity levels, and tumour relapse. Hence, there is a quick requirement for fundamental elective therapeutics, which can be helpful and protect against the said disease. Different phytochemicals derived from natural sources have been discovered to show practical restorative actions against different human infections. One such chemical is Zerumbone, extracted from Zingiber zerumbet Smith that has various pharmacological properties, including cell reinforcement, antibacterial, antipyretic, immunomodulatory, and is also hostile to neoplastic growths. Zerumbone has demonstrated anti-cancer potential by causing critical concealment of multiplication, survival, angiogenesis, and metastasis through various pathways. NF-kB, Akt, and IL-6/JAK2/STAT3 (Interleukin-6/Janus Kinase-2/Signal Transducer and Activator of Transcription 3) are a few examples with their downstream objective proteins. The present audit momentarily sums up the activity and helpful capability of zerumbone against breast malignancy.

Green Hydrogen Production - The Energy of the Future
Authors: Shah Pranay , Upadhyay Harsh
Published: November 2023

Hydrogen is the most efficient energy carrier. It can be obtained from many sources like fossil fuels and water. Most of the energy generation uses fossil fuels, resulting in environmentally unhealthy activities and the production of toxic by-products, which contribute to environmental degradation and climate change. Among many hydrogen production methods, non-polluting and high purity of hydrogen can be obtained by water electrolysis. The produced hydrogen and oxygen can be directly used for fuel cell and industrial applications. Overall water splitting results in only 4% of global industrial hydrogen being produced by electrolysis of water mainly because of economic problems. Nowadays, the increase in demand for green hydrogen has increased the interest in PEM water electrolysis. In this work, we look at various methods of hydrogen production, namely water electrolysis and solar water splitting. This project also briefly describes the applications of green hydrogen along with its effectiveness to replace the current method of hydrogen production.
Proteins from Plants: Are we ready for Revolution?

Published: November 2023

protein is the most important and vital part of the meal. Proteins are involved in stimulating the muscle protein synthesis. The quality of food also depends on the physical, chemical and behavioural characteristics of proteins during its processing. Long-term observational research found a link between high total and animal protein consumption and an elevated risk of cancer and diabetes. In line with the findings of observational research, plant protein is primarily liable for this positive impact. On one hand, animal proteins include all of the required amino acids found within the organic structure, making them extremely nutritious but found the culprit in imposing metabolic stress on the liver, bones, and kidney. Animal proteins have long been accused of contributing to an insufficient nutritional intake profile, which may explain the relationship with heart disease risk.
It is also worth saying that because the vegan, vegetarian, and flexitarian communities have grown, plant proteins became more popular in cuisine. Due to increase in cardiovascular risk and other disease risk, many people are inclining towards the consumption of plant-based proteins. Plant proteins are employed in the manufacture of a large range of natural products. Soy protein isolates were first commercialized in 1959. People are also turning towards a plant protein diet considering the negatives of animal protein, but allergenicity is a back-pulling force.
Plant proteins have lately received more attention as allergens, notably in Europe and therefore the US, furthermore as in relevancy innovative and transgenic foods. The oxidative alterations had a derogatory impact on the functioning of plant proteins eg. soy proteins in general. In both sexes, replacing 3% of energy from diverse protein sources from animal and with plant protein was related to a 10% decline in overall mortality. Plant-based protein consumption have relatively less mortality rate as compared to animal-based protein. Still, animal-based proteins are good source of essential amino acids than plant proteins. The link between protein consumption and mortality might also be explained by the consumption of other nutrients and physiologically active substances in protein-rich diets. Furthermore, a growing amount of clinical data, related to older persons, supports health benefits related to protein intakes that are at or above current dietary protein consumption guidelines but the source of proteins is still a point of debate and hence dilemma is constant of whether we are ready for revolution or not.
A Review on Plant-based Proteins
Authors: Pawar Aditi
Published: November 2023

There has been observed an increasing popularity around the globe in plant-based protein and plant derived alternatives to meat and animal-based products both online and when one visits the supermarkets and grocery stores. The aim of this review is to better understand what impacts this new revolution can have on us and the environment as we know it right now.
From the standpoint of global sustainability, plant-based foods are proposed to be advantageous over animal-based foods. It has been suggested that the production of plant-based foods requires less water, land, and energy. This may ultimately pose less environmental burden and lower the financial cost of food production. These notions likely explain the increasing interest in the potential of using plant-based protein sources in clinical feeding formulas and sports nutrition supplements.
In terms of overall health, it has shown to significantly aid in lowering cholesterol levels in people and therefore reducing the risk of cardiovascular diseases (CVD). Some studies have shown that it helps in controlling type 2 diabetes but the research on that is very little. In terms of menopausal symptoms, studies showed that it was beneficial for those women to have certain plant-based proteins. Understanding the role of plant protein in cancer prevention is discussed.
Other aspects such as muscle growth and its effects on strength are also discussed.

Published: November 2023

Aim: To compare the effectiveness and safety of various methods of professional teeth bleaching using light and chemical activation systems in an in vivo study.
Materials and Methods: Teeth whitening was performed on 48 patients aged 20 to 35, divided into 4 groups. In patients of group 1 for dental bleaching a diode laser activation was used, group 2 – LED/gel activation, group 3 – chemical whitening with the following remineralization therapy, group 4 – chemical whitening without remineralization therapy. The study of the effect of bleaching systems on the hard tooth tissues was carried out by index assessment, determination of biochemical parameters of an oral fluid.
Results: Laser bleaching of the vital teeth was significantly more effective than the other methods with 95% confidence level and did not affect the structure of hard dental tissues and mineral exchange of the oral fluid. LED irradiation has a high whitening effect, but leads to dentin hypersensitivity and a decrease in phosphorus and alkaline phosphatase of oral fluid. Chemical bleaching causes a decrease in enamel resistance, the occurrence of tooth sensitivity, violation of mineral exchange of oral fluid, therefore; it requires combined use with local remotherapy.
Conclusions: Laser teeth bleaching is the effective and safe method in management of discolored teeth. A positive result of its use can be considered an improvement of color change of the teeth by 3.33 shades compared to chemical bleaching, enamel stability, low values of dental hypersensitivity indices, no changes in biochemical parameters of the oral fluid.
Exploring national culture through international media The publication of a viral pro-LGBT image compared against a nation’s wealth, level of religion, and democracy
Authors: Kenix Linda Jean
Published: November 2023

Gay marriage is now legal in 22 countries around the world. However, homosexual acts remain punishable by death in 10 countries and are now illegal in a further 65 countries. Thus, there appears to be very clear national cultural distinctions in how local cultures consider the rights of lesbian, gay, bisexual and transgender (LGBT) people. In 2016, an image of a 12-year-old boy who stood against a sea of anti-LGBT marriage protesters in Celaya, Mexico went ‘viral’ around the world as an icon for LGBT rights. This research will examine newspapers from a sample of 17 countries to see where this particular pro-LGBT image was used. This research asks the question, what is the relationship between the publication of this image and a country’s level of democracy, wealth and religion – socio-economic factors that have been found to be correlated to the acceptance of LGBT rights. The findings of this research could potentially suggest the presence of ideological biases at the national level in regards to how international news stories are told and also which news stories are even addressed. These factors may help to coalesce into a cultural perspective unique to each country examined

Communication Efficacy as a Mechanism for the Chilling Effect on Complaint Avoidance A Cross-cultural Comparison of American and Chinese Romantic Relationships
Authors: Li Yachao , Samp Jennifer A.
Published: November 2023

Complaint avoidance is a common response to relational conflict; yet, it can cause adverse personal and relational consequences. This study examined cultural (i.e., U.S. versus China) and relational (i.e., relational power, communication efficacy) factors predicting complaint avoidance. Hypothesizing that Americans engage in less complaint avoidance than Chinese (H1), relational power negatively predicts complaint avoidance via communication efficacy across cultures (H2), and culture moderates how power and efficacy predict avoidance (H3), we surveyed 392 college-aged dating individuals (194 Americans, 198 Chinese). Results confirmed H1 and H2. H3 was partially supported: after controlling for relational and conflict characteristics, as communication efficacy increased, there were greater decreases in complaint avoidance in Americans than in Chinese. Implications for cross-cultural studies on relational conflict are discussed.
Social Desirability Bias among Prejudice Instruments An Integrated Threat
Authors: Croucher Stephen M , Nshom Elvis , Rahmani Diyako , Zeng Cheng
Published: November 2023

A considerable amount of research has examined the extent to which members of dominant cultures perceive minority groups as threatening their way of life. While various instruments measure these perceptions of threat, few researchers have empirically analysed the statistical properties of these scales. Specifically, studies have not adequately explored social desirability of threat scales. The current study investigates the extent to which one set of threat scales is internally consistent or reliable (González et al., 2008), and explores social desirability within the González et al. (2008) integrated threat instruments by comparing self-reports to other reports (intimate other and friend reports). Results indicate the instruments are internally consistent and that self-reports and other reports of threat do not differ on most indices of threat.

The Mismeasure of Culture Self-Report Questionnaires and Positivist Analysis in Intercultural Communication Research
Authors: Nield Stewart
Published: November 2023

The use of self-report questionnaires has been one of the most prevalent methods of data collection in Intercultural Communication research since as early as the 1950s. Yet, the method has received widespread criticism from a range of academic disciplines. For the field of Intercultural Communication, there is the added concern that self-report data and its epistemological companion, quantitative analysis, succeed only in reducing complex intercultural issues to an overly-simplistic numerical summary. Despite these criticisms, the number and influence of self-report questionnaires in Intercultural Communication research continues to grow. Therefore, this paper seeks to remind researchers of the many problems existing when asking respondents to self-report on complex intercultural issues. By way of an example, Ang et al’s (2007) Cultural Intelligence Scale (CQS) will be analysed through a critically interpretive approach.

The purpose of this study was to examine the ways in which rhetorical strategies, as a sub-genre of persuasive discourse, are deployed in scholarship application letters in Iran in Persian and English. To this end, 96 application letters fora fictitious scholarship were written by Iranian university students and were further analyzed according to a framework initially proposed by James, Scholfield and Ypsilandis (1994). Aristotle’s taxonomy of logos, ethos and pathos was employed to examine the rhetorical organization or moves in this sample and a mixed analysis with quantitative statistics and qualitative comments was followed. The results showed significant differences in the use of strategies between the two versions of the data collected (Persian and English) in different parts of the letters, such as greetings, openings, self-presentation, and letter closing. On the other hand, it was observed that the most frequently rhetorical appeals selected by the applicants lie under the logos and pathos categories in both Persian and English letters.

This research includes laboratory experiments with the sample as a pure culture of Streptococus sanguinis obtained from the Microbiology Laboratory of North Sumatra University Hospital. There were 5 treatment groups (starfruit extract concentration 6.25%, 12.5%, 25%, 50%, 75%), positive control (chlorhexidine 0.2%), and negative control (DMSO). The antibacterial effect was tested using the disc diffusion method. Then, the data was analyzed using statistical tests, one-way ANOVA, and, after this, LSD. The research results were obtained mean, and standard deviation of the diameter of the inhibition zone of star fruit extract, concentrations of 12.5%, 25%, 50%, 75%, and positive control for bacteria Streptococus sanguinis were 7.05 ± 0.192 mm, 9.38 ± 0.171 mm, 13.38 ± 0.171 mm, 14.30 ± 0.216 mm, and 14.38 ± 0.096 mm, while the concentration of star fruit extract was 6.25% and the negative control no inhibition zone was found. Test results from one-way ANOVA revealed that there was a significant antibacterial effect of star fruit extract against the bacteria Streptococus sanguinis (p≤0.05). Test results after this LSD found that the antibacterial effect of the 75% concentration extract was not significant with the positive control, and the 6.25% concentration was not significant with the negative control (p>0.05). From the research results, it can be concluded that the higher the concentration of the extract, the higher the antibacterial effect, with the most effective concentration being 75% and the MIC at a concentration of 12.5%.

Population outbreaks, although rare, hold significant ecological implications, particularly in short-lived organisms. These outbreaks are often triggered by changes in population control factors such as food availability, absence or reduction of natural enemies, diseases, or favourable climatic conditions. This study documents an infestation event where the scarab beetle Macrodactylus pumilio Burm., 1855 (Coleoptera: Scarabaeidae) heavily infested a specimen of Cecropia pachystachya Trécul. in, Serra do Cipó, Minas Gerais, Brazil. The infestation took place at the onset of the rainy season, which corresponded with the annual emergence of the beetles from the soil. We searched another nine fruiting trees within 100 m radius, none of which were infested. The estimated abundance of M. pumilio beetles on the infested tree reached 45,825 insect individuals. The insect is a known agricultural pest, affecting citrus, passion fruit, coffee plantations, and ornamental flowers. C. pachystachya, a pioneer tree commonly found in secondary forests of Latin America, may represent a potential alternative host for the beetles in the face of increasing pesticide use.  This event may have significant implications for the population dynamics of C. pachystachya and highlights the importance of understanding the life cycle and behaviour of species of the genus Macrodactylus Dejean, 1821. Similar outbreaks have been reported in agricultural systems, emphasizing the need for precise knowledge to plan effective management strategies in both natural and agricultural environments.
