Протоатом и его роль в формировании величины гравитационной постоянной. Квантовые состояния протоатомов. Результаты исследования.
Authors: Чернов Андрей 
Published: July 2023

В основе этого исследования лежит утверждение, что гравитационное сжатие больших космических масс имеет предел плотности сжатия. При этом первоначальная масса, состоящая из атомов, превращается в однородную, очень плотную массу (чёрную дыру), состоящую из одинаковых частиц (которые в исследовании были названы протоатомами).
В этом исследовании для определения параметров протоатома было использовано решение Шварцшильда. В результате была определена масса протоатома, а дальше через математические расчёты с использованием независимых физических постоянных была получена величина двух элементарных зарядов протоатома. Полученная величина заряда совпала с рекомендованной CODATA величиной элементарного заряда. Расхождение составило всего 0,098%, что подтвердило существование протоатома. Этот результат также интересен тем, что величина элементарного заряда была определена через другие независимые физические константы.
В этом исследовании была получена формула для расчёта величины гравитационной постоянной G. По этой формуле были произведены расчёты величины гравитационной постоянной у 24 химических элементов, взятых из всех групп таблицы Менделеева. Полученные результаты показали, что значение G может колебаться пределах тысячных и сотых долей процента. Также была определена величина гравитационной постоянной в гравитационном поле наиболее массивных чёрных дыр.
В этом исследовании по аналогии с дискретностью энергетических состояний атомов водорода, были исследованы квантовые состояния протоатомов. В результате с использованием полученных физических параметров протоатома была получена формула для расчёта квантов энергии гравитационных волн (гравитонов), испускаемых чёрными дырами. По этой формуле был рассчитан линейный ряд энергии гравитонов. Полученные значения энергии гравитонов уверенно согласуются с результатами астрофизических наблюдений гравитационных волн, которые возникли в результате слияния чёрных дыр. В ходе анализа новой формулы была определена масса электрона через 4 фундаментальные константы (G, c, q, h). Результат совпал с экспериментальной массой электрона. Были получены другие результаты, имеющие научное значение.

European Union military operations and global security: ambitions and reality
Authors: Aguilar Sergio Luiz Cruz 
Published: July 2023

In the last twenty years, the European Union (EU) has made notable efforts in improving its military capabilities to react to crises. The Union launched crisis management missions and operations, aiming to play a relevant role in the field of international security. Thirteen military operations and missions were established amongst its overseas action to date. Notwithstanding, the results are questionable, i.e. the positive relationship between what the EU says, and its concrete action in practice. The paper aims to present what is the real role of EU military operations by arguing that although high ambitions the Union’s military interventions are still limited. It is demonstrated by using a model with proxies from inputs to impacts through which I analyse perceptions and intentions and how they have been translated into effective implementation. I used quantitative data combined with certain qualitative remarks collected from primary and secondary sources. It concludes that the EU military operations remain more as ambitions than to project its best features in favour of a better world security environment

Madrasah Nahdlatul Wathan Diniyah Islamiyah (NWDI) is a forum for the national movement for youth, especially in the field of education. In addition to education, NWDI has a practice or prayer compiled by TGKH. Muhammad Zainuddin Abdul Majid, i.e. hizib NW. In addition to NW hizib, there are also sholawat readings that are still read by the NWDI community, especially among NWDI mahad such as al-barzanji and adhiya ullami. Adhiya ullami is also a practice of NWDI citizens which is read every Friday night, usually NWDI residents read adhiya ullami as serakal. Serakal or serakalan is a traditional Islamic religious ritual that combines verses in praise of Allah and His Messenger. The media used to learn the NWDI version of Sholawat Adhiya Ullami still uses media in the form of books or print media. The number of books is still limited so that not all people have the book, especially for beginners who still do not understand reading and have adhiya ullami books so it is difficult to learn. The objectives of this study are 1) Designing a complete, easy-to-understand and quality android-based adhiya ullami application as a source for sholawat readings for NWDI residents, 2) Knowing the feasibility results of the adhiya ullami application by experts and 3) Knowing user responses to the adhiya ullami application for NWDI residents. ADDIE model research methodology with stages of analysis, design, development, implementation and evaluation. The stages of research carried out until the implementation stage with limited-scale trials. The data collection technique uses questionnaires addressed to Media experts, Media experts and 30 people as user responses. The data analysis technique used is quantitative descriptive. The result of this study is the NWDI Version of the Adhiya Ullami Application. The results of the material expert test obtained a value of 93.5% (very feasible), the media expert test obtained a value of 93.5% (very feasible), and the results of user responses obtained a value of 90.5% (very high). Thus, it can be concluded that this application is feasible to use and has a high response as a medium for reading sholawat adhiya ullami by NWDI residents.

IntroductionWe are having pressing issues of global food insecurity and malnutrition. Mesopelagic communities in the North Atlantic have been estimated to have high biomasses of organisms. Some of these low-trophic organisms are known to be nutrient-dense and may thus contribute to food security and nutrition. Here, we aim to understand the variation in nutrient and undesirable substance concentrations in a common mesopelagic species, Maurolicus muelleri in the North Atlantic Ocean.MethodsWe sampled the M. muelleri from the Bay of Biscay (BB), Norwegian fjords (NF), and the North Sea (NS). The concentrations of micro- and macronutrients, undesirable metals, and persistent organic pollutants (POPs) were measured in composite whole fish samples.ResultsWe found no difference across the sampling areas in the selected micronutrients except that the NF and NS samples had higher vitamin A1 concentrations than the BB samples. The NF samples had higher concentrations of fat, fatty acids, and POPs but lower concentrations of cadmium than the BB and NS samples; the differences in fat and fatty acids were only marginal in the NF-BB pair. The BB samples had lower arsenic concentrations than the NS samples, and lower concentrations of erucic acid and mercury than the NF and NS samples. Comparing the measured values against existing EU regulation values for nutrients and undesirable substances for human consumption, we found that the samples from NS and BB may cause food safety concerns due to their high cadmium concentrations, while the M. muelleri from all the sampling areas are qualified as good sources of iron, selenium, vitamin A1, and ω-3 fatty acids.DiscussionThis study confirms that M. muelleri from the North Atlantic Ocean may play an important role in food security and nutrition. However, potential variations in nutrient and undesirable substance concentrations related to seasonality, fish body size, and maturity level shall be taken into consideration prior to exploiting such a marine resource. Further understanding of trophic ecology, life cycles, and productivity of M. muelleri is essential to investigate the drivers behind the observed variation in nutrient and undesirable substance concentrations.
A comprehensive meta-analysis reveals the key variables and scope of seed defense priming
Authors: Talavera-Mateo Lucia , Garcia Alejandro , Santamaria M. Estrella 
Published: July 2023

BackgroundWhen encountered with pathogens or herbivores, the activation of plant defense results in a penalty in plant fitness. Even though plant priming has the potential of enhancing resistance without fitness cost, hurdles such as mode of application of the priming agent or even detrimental effects in plant fitness have yet to be overcome. Here, we review and propose seed defense priming as an efficient and reliable approach for pathogen protection and pest management. MethodsGathering all available experimental data to date, we evaluated the magnitude of the effect depending on plant host, antagonist class, arthropod feeding guild and type of priming agent, as well as the influence of parameter selection in measuring seed defense priming effect on plant and antagonist performance. ResultsSeed defense priming enhances plant resistance while hindering antagonist performance and without a penalty in plant fitness. Specifically, it has a positive effect on crops and cereals, while negatively affecting fungi, bacteria and arthropods. Plant natural compounds and biological isolates have a stronger influence in plant and antagonist performance than synthetic chemicals and volatiles. DiscussionThis is the first meta-analysis conducted evaluating the effect of seed defense priming against biotic stresses studying both plant and pest/pathogen performance. Here, we proved its efficacy in enhancing both, plant resistance and plant fitness, and its wide range of application. In addition, we offered insight into the selection of the most suitable priming agent and directed the focus of interest for novel research.

BackgroundAntiretroviral therapy (ART) has led to diminishing AIDS-related mortality but a concomitant increase in non-communicable diseases (NCDs) for people with HIV (PWH). Whereas physical activity (PA) has been shown to help prevent NCDs and NCD outcomes in other settings, there are few data on PA and its correlates among PWH in high-endemic settings. We aimed to compare PA by HIV serostatus in rural Uganda.MethodsWe analysed data from the UGANDAC study, an observational cohort including PWH in ambulatory HIV care in Mbarara, Uganda, and age- and gender-matched people without HIV (PWOH). Our primary outcome of interest was PA, which we assessed using the International Physical Activity Questionnaire and considered as a continuous measure of metabolic equivalents in minutes/week (MET-min/week). Our primary exposure of interest was HIV serostatus. We fit univariable and multivariable linear regression models to estimate the relationship between HIV and PA levels, with and without addition of sociodemographic and clinical correlates of PA (MET-min/week). In secondary analyses, we explored relationships restricted to rural residents, and interactions between gender and serostatus.ResultsWe enrolled 309 participants, evenly divided by serostatus and gender. The mean age of PWH was 52 [standard deviation (SD) 7.2] and 52.6 (SD 7.3) for PWOH. In general, participants engaged in high levels of PA regardless of serostatus, with 81.2% (251/309) meeting criteria for high PA. However, PWOH reported higher mean levels of PA met-minutes/week than PWH (9,128 vs 7,152, p ≤ 0.001), and a greater proportion of PWOH (88.3%; 136/154) met the criteria for high PA compared to PWH (74.2%; 115/155). In adjusted models, lower levels of PA persisted among PWH (β = −1,734, 95% CI: −2,645, −824, p ≤ 0.001). Results were similar in a sensitivity analysis limited to people living in rural areas.ConclusionIn a rural Ugandan cohort, PWOH had higher levels of PA than PWH. Interventions that encourage PA among PWH may have a role in improving NCD risk profiles among PWH in the region.

Published: July 2023

IntroductionSoybean breeding in southwestern China has vastly improved soybean yields with the increasing demand for nutrients such as phosphorus (P) and nitrogen (N). This study aimed to assess the impact of soybean breeding on P and N utilization efficiencies.MethodsField experiments with split-plot experimental designs were conducted at two locations [Dafang (DF) and Shiqian (SQ)] in the 2019 growing season to determine the agronomic efficiency of P fertilizer (AEp), P and N utilization efficiencies, and P and N accumulation and partitioning in different soybean organs under 0 (P0) and 35 (P35) kg ha−1 P supply.ResultsThe results showed that soybean breeding targeting high seed yield also improved AEp (p &lt; 0.05) and P (p &lt; 0.05) and N utilization efficiencies (p &lt; 0.05), with the improvement in AEp associated with the high yield response to P supply. P and N accumulation significantly increased in pods (p &lt; 0.05) and leaves (p &lt; 0.05) but not in stems or roots with year of release, while P and N concentrations did not change in any organ with year of release. In addition, only pod dry weight significantly increased (p &lt; 0.01) with year of release, and P and N partitioning increased to pods (p &lt; 0.05) but decreased to stems (p &lt; 0.05) with year of release. Correlation and PCA analyses revealed P and N utilization efficiencies positively correlated with P and N partitioning to pods but negatively correlated with P and N partitioning to stems. While P supply increased P and N accumulation, it reduced P utilization efficiency.DiscussionWe conclude that (1) soybean breeding improved AEp and P and N utilization efficiencies; (2) the increased P and N partitioning to pods but decreased partitioning to stems contributed to the high P and N utilization efficiencies in new soybean cultivars, reducing the demand for N and P; (3) P supply increased nutrient accumulation but reduced P utilization efficiency. These results highlight the significance of appropriate resource allocation among organs and efficient P management for enhancing nutrient utilization and reducing fertilizer requirements.

The ERF gene family is widely present in plants and has crucial regulatory importance in plant seed development, organ morphogenesis, the synthesis of secondary metabolites, and coping with abiotic stresses such as cold and drought. In this study, 90 members of CsERF were screened by bioinformatics tools analysis and named CsERF1–CsERF90. Their molecular characteristics and systematic evolution were studied, and the tissue expression characteristics of CSERF genes and the composition of promoter cis-acting elements were predicted. The results showed that 81 proteins encoded by CsERF genes had conserved motifs 1, 2, and 3, while 64 members possessed other motifs. The theoretical isoelectric point was between 4.49 and 10.24, and 85 members constituted unstable proteins, while the rest were stable proteins. Subcellular localization predicted that 77 members were in the nucleus, 8 were in the chloroplasts, and 5 were in the mitochondria. The promoter sequence of CsERFs was found to include not only cis-acting elements related to hormone regulation, such as gibberellin (41), methyl jasmonate (110), and abscisic acid (185), but also cis-acting elements involved in low-temperature response (56) and light response (22), indicating that CsERFs have a key role in plant growth and abiotic stress. Phylogenetic analysis of tea plant and Arabidopsis thaliana ERF gene families showed that the tea plant ERF gene families could be divided into six groups, with B3 having 29 members at most and B1 having only 3 members at least. The phylogenetic tree constructed using only the CsERF genes is also divided into six groups, with slightly different but minimal differences in members. Of the 90 tea plant ERF members, 85 were located on 15 chromosomes, whereas 5 were not located on chromosomes. The collinearity analysis showed that there were 41 homologous gene pairs among the CsERFs, and these homologous gene pairs may have the same function. According to the expression of CsERFs in cold-stressed tea plant and in different tissues, 90 CsERF genes played their respective roles in different tissues and stages to regulate plant growth, and some of them participated in the process of cold stress tolerance. This study provides a theoretical foundation for the study of tea plant growth and development and low-temperature resistance.

Published: July 2023

The Covid-19 pandemic has made Indonesia's tourism business sluggish and less interested. For example, Bali tourist visits as a popular destination decreased by 99.9% (Central Statistics Agency of Bali Province, 2020). Based on Wonderful Indonesia, foreign tourist visits in April 2019-2020 decreased by 87%. A thorough collapse has bankrupted many tourism businesses. Based on this phenomenon, researchers are interested in researching people's interest in carrying out traveling activities, judging from the variables situational influence (Covid-19), risk perception and an advertising appeal. This research is quantitative with population of people who have carried out traveling activities within the last 2 years. The study sample using Non-Purposive Probability totaled 150 respondents. Analysis of the study using multiple linear regression with SPSS software. The results showed that Situational Influence has a positive and significant influence on Purchase Intention. Risk perception has a negative and significant influence on Purchase Intention. Advertising Appeal has a positive and significant influence on Purchase Intention.
