The present study was accomplished to assess and compare tree diversity, carbon stock, and to find the relationship between carbon stock and tree diversity in scientifically and conventionally managed community forests (CFs) of Kanchanpur District, Nepal. A total of 94 sample plots were overlaid with a systematic random sampling method (51 plots in scientifically managed Singhapur CF and 43 plots were established in conventionally managed Kalika CF). The height and DBH of each tree were measured to calculate biomass and carbon stock. Shannon-Wiener and Simpson’s indexes were calculated for tree diversity. The data were pooled and analyzed using MS Excel and SPSS software. The values were statistically compared using a t-test. The total carbon stock and tree diversity were higher in scientifically managed CF (207.58 tons/ha and H= 0.97) than conventionally managed CF (183.72 tons/ha and H=0.85). Shorea robusta has a major contribution on total carbon stock in both CFs (Kalika: 66.34% and Singhapur: 70.43%) followed by Terminalia tomentosa (Kalika: 24.65% and Singhapur: 13.36%). The t-test did not show any significant difference for the mean values of carbon stocks and tree diversity between the CFs at a 5% level of significance. However, carbon stock showed a weak but positive relationship with species richness and negative with evenness. The result of the study recommends managing forests scientifically for increased tree diversity leading to enhanced carbon deposition.

the purpose of our research is to propose psychological factors of class-room facilitative management at secondary schools.methods of the research. The following theoretical methods of the research were used to solve the tasks formulated in the article: the categorical method, structural and functional methods, the methods of the analysis, systematization, modeling, generalization. Also in our research the statement experiment was used as an empirical method.the results of the research. We’ll identify the principles that should guide the teacher, who seeks to humanize interpersonal relationships with pupils: 1) from the very beginning and during the whole learning process the teacher needs to show the children his/her trust in them, in their personality; 2) pupils should be assisted in formulating and clarifying the goals and objectives that are formulated both for micro-groups and for each pupil individually; 3) we must always assume that pupils have an intrinsic motivation for the learning process; 4) the teacher should be a source of personal experience for pupils, which can always “be turned to” for the help of other people, be faced with difficulties in solving a problem; 5) it is important that this role is performed by the teacher in relations to each pupil; 6) the teacher should strive to develop the ability to feel the emotional mood of the micro-group and understand it; 7) we should strive to achieve empathic relationships that allow us to understand the feelings and the experiences of everyone; 8) the micro-group should actively demonstrate their feelings; 9) it is necessary to be an active participant in group facilitative interaction.conclusions. As a result of comparative studies, which in total surveyed 57 teachers and 92 pupils, we compared different performance indicators of teac-hers who had the ability to facilitate learning at different levels. The analysis of he behavior of pupils in the classes of teachers-facilitators showed that pupils were more proactive in the process of communication, they asked a lot of ques-tions. Pupils spend more time solving learning tasks and problems, show higher levels of cognitive functioning. Pupils are also less likely to miss classes, demon-strate higher academic achievements in all disciplines, steadily increase their IQ and creativity throughout the school year.

In the article it was shown, that human feelings act as an experience of “Me”, and in this regard it is as external monologues, and on the other hand they are dialogical in nature, they can hear a broken dialogue with others: appeals, questions, expected answers, desires that are not expressed, accusations, etc., that exists in a covert form of internal dialogue. Un-der the dialogical analysis of the case we understand the reconstruction of the movement of internal dialogue, which becomes possible as a result of a special attitude to the text (for this purpose, special methods of textual analysis were developed).conclusions. Theinner speech was showed to be the speech for himself/herself. External speech is speech for others. Psychologically, the language of the pupil in functional and structural terms is egocentric speech, it is not under-stood as internal speech and is not separated by the child from speech for others. Objectively, this language is a function differentiated from social thinking, but again inconsistent, because it can only function in a situation that makes social speech possible.

An extensive use of the concept of online study-ing and the development of its technical internal system capabilities have led to significant changes in the understanding of this term. We define it as a global as-sociation of computer networks, an integrated network, web-sites, consisting of different communication networks integrated into a single logical online system. However, this definition no longer covers all aspects of this phenomenon. Accor-ding to the field of Online Psychology we mean online studying not as a specific network of interconnected computers and mobile devices, or even a network of web-sites with channels and communication devices between components with appropriate programs and protocols, as networks together with social services based on them, which attract people and / or ensure their activities. conclusions. Thus, virtual discourse shapes the linguistic consciousness of a nation, social representations, general opinions, patterns of the person’s be-havior, frames and scenarios or even scripts. We have proved that the Internet environment is an effective factor in shaping personal value system. It is focused that digital technologies, for example the Internet, change not only conscious-ness and behavior, but also their physiological basis of the person, so, the brain.

Son on yıl içerisinde doğalgaz piyasalarına arz yönlü en önemli katkılardan birini sağlayan Doğu Akdeniz’deki keşifler, bölge jeopolitiği açısından da önemli etkiler yaratmıştır. Yeni yer altı zenginliklerinin ortaya çıkarılması hem yaratacağı rant sebebiyle hem de stratejik etkisinden dolayı tüm siyasi aktörlerin iştahını kabartmaktadır. Doğu Akdeniz’de de geniş bir coğrafyaya yayılan doğalgaz keşiflerinin benzer bir dinamiği harekete geçirme ihtimalinden söz edilebilir. Üstelik doğalgazın boru hatlarıyla taşınmasından sıvılaştırılarak hedef pazarlara sevk edilmesine kadar çeşitlendirilebilecek bir dizi seçenek bu rekabeti daha da artırmakta ve tarafların çatışma ihtimalini artırmaktadır. Özellikle Arap Baharı ve Suriye İç Savaşı ile tırmanan siyasi gerilimlerin de en azından bir yönüyle bu dinamikle irtibatı olduğunu söylemek mümkündür. Diğer taraftan, klasik liberal perspektif bu yeni buluntuların ülkeler arası iş birliği fırsatları doğurabileceğini, çatışma zemini hazırlamak bir yana karşılıklı çıkar temelinde inşa edilecek bir barış fırsatı sunabileceğini öngörmektedir. Ana hatlarıyla bu farklı iki çekim gücünün bölgesel güç dinamikleri açısından ele alınması Doğu Akdeniz jeopolitiğinin anlaşılması için önem taşımaktadır.
The Centenary of the Pioneer Movement: history and lessons
Authors:   Vyatka State University, Pomelov Vladimir B.
Published: July 2022

Introduction. The problem of studying the history of the All-Union Pioneer Organization (AUPO) named after V.I. Lenin, which for a long time (1922-1991) played an important role in the education of the younger generation in the USSR, is of relevance, theoretical interest and practical value for modern Russian teachers in terms of studying the glorious past of our country in general and the pioneer organization in particular, restoring historical justice against a number of prominent teachers of the past, and using the experience accumulated by Soviet teachers-practitioners in organizing work with the younger generation today. The purpose of the issue is to study circumstances of the occurrence and characterization of the most important events in the history of the AUPO, to show the value content of its activities. Materials and methods. Research methods – analysis of historical, pedagogical, methodological and fiction literature on the subject of research, biographical and historical methods, axiological approach in revealing valuable content in the structure of the characterized facts and phenomena. Results. In the Russian historical and pedagogical science in the last three decades, there are practically no materials concerning the theory and practice of the work of the AUPO, its history and prospects for using the experience of its work in modern conditions. Significant stages of the AUPO genesis were awarded with state awards, reflected in cinematography and fiction. Along with the periodically changing official «Rules of the Pioneers», which regulated the activities of the AUPO, local traditions, children’s «oaths», the uniform of young communists and pioneers played a significant place in their lives. Such, for example, was the solemn ceremony «Octobrin», in which the pioneer E.I. Monoszon, the future academician of the USSR Academy of Pedagogical Sciences, took part. Discussion of the results. At all stages of its activity, the AUPO combined significant achievements and shortcomings, primarily bureaucracy, formalism and paperwork. The defining indicators of the work of school pioneer organizations were successful reporting, numerous demonstration events. The real interests of the pioneers were often ignored. But still, the main reason for the liquidation of the AUPO was the cardinal socio-political events of the early 1990s in the USSR. Conclusion. Currently, there is an urgent need to use the experience of AUPO in the work of existing children’s educational organizations.

Introduction. The analysis of normative documents which regulating the sphere of education indicates the importance of social and educational functions in the activities of classroom teachers. For the successful implementation of these functions, class teachers must have the appropriate competencies. The purpose of the work is to determine the level of formation of social and learning competencies among potential (students) and actual classroom teachers in the Sverdlovsk region, and to offer recommendations for organizing their professional and post-professional training on the basis of a pedagogical university. Materials and methods. The empirical study was carried out in three stages: at the first stage, through testing (n=528); on the second – through the method of scaling subjective assessments of readiness for the implementation of the main areas of socio-pedagogical activity of the classroom teacher (n=2356); on the third – through a survey of students (n=438) about the implementation of their functions by class teachers. Base of research: Ural State Pedagogical University (Russian Federation) Research results. As a result of the first survey, it was revealed that the level of development of knowledge about the methods of socio-pedagogical activity based on an individual approach, especially towards children and adolescents with developmental disabilities, among class teachers is extremely low – only 7%. The second survey showed that the activity component of socio-pedagogical competencies was formed at the “below average” level in social prevention, social rehabilitation and human rights content areas. In the process of the third study, it was determined that organizational-coordinating and information-communicative meaningful areas of activity prevail in the work of class teachers. And in fact, the analytical and prognostic, social and preventive, social and rehabilitation and human rights areas are not represented. Conclusion. Based on the results, recommendations were developed on the organization of professional training of class teachers on the basis of a pedagogical university.

Membranous nephropathy may present in any age group. While it is one of the most common causes of adult nephrotic syndrome, it is a rare histologic entity in the paediatric population. In adults it is more commonly classified as primary or idiopathic. In contrast, among children and adolescents, it is more frequently secondary to systemic disorders or drug exposures. One of the potentially implicated drugs is penicillamine, which has long been used as first-line therapy for symptomatic children with Wilson’s disease. We report a case of an adolescent treated with penicillamine for Wilson’s disease, who presented with overt nephrotic syndrome due to membranous nephropathy. As most of our knowledge about children and adolescents with membranous nephropathy has been based on extrapolations from adult studies, paediatric case reports may provide useful insights. We also aimed to emphasize the importance of proteinuria close monitoring in patients under treatment with penicillamine to allow for timely consideration of the drug withdrawal.

Published: July 2022

The study of land use/land cover dynamics has been increasingly important in the research of earth surface natural resources. The normalized difference vegetation index (NDVI) is a widely used method for observing land use/land cover change detection. The surface land resources are easily interpreted by computing their NDVI. This study aimed at analyzing Land Use/Land Cover (LULC) changes between 1977 and 2019 in the Rangamati district, Bangladesh using reclassify the NDVI values of the Landsat satellite image and identifying the main drivers to change LULC by household survey. Five different years of Landsat images were used to extract the NDVI values January of 1977, 1989, 2000, 2011 and 2019. The NDVI values are initially computed using the user define method to reclassify the NDVI map to create land use land cover map and change detection. The highest NDVI value was found in 1977 (0.88) which indicates healthy vegetation at that time and thereafter it followed a decreasing trend (0.79 in 1989, 0.74 in 2000, 0.71 in 2011 and 0.53 in 2019) which shows a rapid vegetation cover change in the study area. Analysis of the household survey revealed that population growth, migration from plain land, rapidly urbanization, Kaptai Dam, migration policy of government, high land price, unplanned development, development of tourism industry, firewood collection and poverty have been identified as the major drivers of LULC changes in the study area. Furthermore, analysis of NDVI confirms that the forest vegetation area is being decreased and settlement area and sparseness of vegetation are being increased. The accuracy of the NDVI-based classified images is assessed, using a confusion matrix where overall classification accuracy and Kappa coefficient are computed. The overall classification accuracy was 84% - 90% with corresponding Kappa statistics of 80% - 88% for TM and OLI-TIRS images, respectively. The study serves as a basis of understanding of the LULC changes in the southeastern part of Bangladesh.

Published: July 2022

Fe82Si8B10 amorphous ribbon which containing 82% of Fe and 18% of B and Si were prepared using rapid solidification technique. The samples were constantly annealed for 1 hour in the temperature range of 350°C-600°C. X-ray diffraction analysis (XRD) displays a large peak which is the diffusion hallow suggesting the amorphousity in its origin and formation of crystalline phase with the increment of annealing temperature at 450oC. The magnetic ordering of the ribbon is determined as temperature functions by both AC and DC magnetization. At 450°C, the saturation magnetization (Ms) was found 143 emu/gm and with better value of real part of initial permeability at 450°C as well as better relative quality factor (RQF) was observed at the same temperature. The results are explained as due to higher heating rates than this Si diffuse in amorphous and lost the soft magnetic properties.

Published: July 2022

Urbanization causes major urban pressures and changes in habitat, ecology, and environmental diversity. Particularly in developing countries, they are often characterized with strong urban sprawl. This research aimed to detect the temporal LULC change with the driving forces of LULC and forecast the future LULC via simulation in Rajshahi, Bangladesh. The LULC was classified through supervised classification using Erdas Imagine. To predict future land-use/ land cover change, the Land Change Modeler (LCM) of Terrset application was used with the implementation of CA and Markov chain analysis. “Built-up area” and “bare land” increased whereas “water bodies” and “vegetation” landforms decreased from 1991 to 2011. Although, “builtup area” and “vegetation” increased as “water bodies” and “bare land” decreased from 2001 to 2021. The driving forces of the LULC change were identified through correlation. The conventional driving forces were found to be ‘population,’ ‘literacy rate,’ ‘population density,’ ‘household income’ and ‘average household size’. When the outcome of the coefficient is positive, the driving force works proportionally. Average accuracy of the prediction model is approximately 85% and the predicted image was validated with the classified image of 2021 and the average accuracy was 92.03%. LULC for the years 2001, 2011 and 2021 along with the driving forces served as the basis to predict land-use/land cover for 2031, and 2041. This research helps to analyse urban planning policies and environmental management, and to take proper measure for proper control of LULC change

Slide Presentation on the Riemann Hypothesis
Authors: Vega Frank
Published: July 2022

The Riemann Hypothesis is a conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part 1/2. In 2011, Patrick Solé and Michel Planat stated a new criterion for the Riemann Hypothesis. We prove the Riemann Hypothesis is true using this criterion.

Open-source research software has proven indispensable in modern biomedical image analysis. A multitude of open-source platforms drive image analysis pipelines and help disseminate novel analytical approaches and algorithms. Recent advances in machine learning allow for unprecedented improvement in these approaches. However, these novel algorithms come with new requirements in order to remain open source. To understand how these requirements are met, we have collected 50 biomedical image analysis models and performed a meta-analysis of their respective papers, source code, dataset, and trained model parameters. We concluded that while there are many positive trends in openness, only a fraction of all publications makes all necessary elements available to the research community.
Programmable RNA-Guided Large DNA Transgenesis by CRISPR/Cas9 and Site-Specific Integrase Bxb1

Published: July 2022

The inability to insert large DNA constructs into the genome efficiently and precisely is a key challenge in genomic engineering. Random transgenesis, which is widely used, lacks precision, and comes with a slew of drawbacks. Lentiviral and adeno-associated viral methods are plagued by, respectively, DNA toxicity and a payload capacity of less than 5 kb. Homology-directed repair (HDR) techniques based on CRISPR-Cas9 can be effective, but only in the 1–5 kb range. In addition, long homology arms—DNA sequences that permit construct insertion—of lengths ranging from 0.5 to 5 kb are required by currently known HDR-based techniques. A potential new method that uses Cas9-guided transposases to insert DNA structures up to 10 kb in length works well in bacteria, but only in bacteria. Surmounting these roadblocks, a new toolkit has recently been developed that combines RNA-guided Cas9 and the site-specific integrase Bxb1 to integrate DNA constructs ranging in length from 5 to 43 kb into mouse zygotes with germline transmission and into human cells. This ground-breaking toolkit will give researchers a valuable resource for developing novel, urgently needed mouse and human induced pluripotent stem cell (hiPSC) models of cancer and other genetic diseases, as well as therapeutic gene integration and biopharmaceutical applications, such as the development of stable cell lines to produce therapeutic protein products.
Microtubules in Microorganisms: How Tubulin Isotypes Contribute to Diverse Cytoskeletal Functions
Authors: Bera Abesh , Gupta Mohan L.
Published: July 2022

The cellular functions of the microtubule (MT) cytoskeleton range from relatively simple to amazingly complex. Assembled from tubulin, a heterodimeric protein with α- and β-tubulin subunits, microtubules are long, hollow cylindrical filaments with inherent polarity. They are intrinsically dynamic polymers that utilize GTP binding by tubulin, and subsequent hydrolysis, to drive spontaneous assembly and disassembly. Early studies indicated that cellular MTs are composed of multiple variants, or isotypes, of α- and β-tubulins, and that these multi-isotype polymers are further diversified by a range of posttranslational modifications (PTMs) to tubulin. These findings support the multi-tubulin hypothesis whereby individual, or combinations of tubulin isotypes possess unique properties needed to support diverse MT structures and/or cellular processes. Beginning 40 years ago researchers have sought to address this hypothesis, and the role of tubulin isotypes, by exploiting experimentally accessible, genetically tractable and functionally conserved model systems. Among these systems, important insights have been gained from eukaryotic microbial models. In this review, we illustrate how using microorganisms yielded among the earliest evidence that tubulin isotypes harbor distinct properties, as well as recent insights as to how they facilitate specific cellular processes. Ongoing and future research in microorganisms will likely continue to reveal basic mechanisms for how tubulin isotypes facilitate MT functions, along with valuable perspectives on how they mediate the range of conserved and diverse processes observed across eukaryotic microbes.

During the second year of the COVID-19 pandemic, the use of Rapid Diagnosis Antigen Tests (RDAgTs) for SARS-CoV-2 detection has substantially increased as some of the brands available in the market were certified for clinical use by international regulatory agencies. RDAgTs are a fast and cheap tool for SARS-CoV-2 surveillance with great potential to improve testing capacities in middle- and low-income countries compared to the gold standard RT-qPCR. However, as the clinical performance of RDAgTs has been shown to vary greatly between the commercial brands available, evaluation studies are necessary. Moreover, the available evaluation has been done in high-income countries while SARS-CoV-2 transmission is also actively happening in developing countries, many of which are located in tropical latitudes where cross-reactivity with other infectious agents is highly prevalent, which could compromise RDAgT specificity. Moreover, unreported mutations and/or new SARS-CoV-2 variants may compromise RDAgT sensitivity as genomic surveillance is limited in these settings. Here we describe a multicenter and manufacturer‐independent evaluation of the clinical performance and analytical sensitivity of three different RDAgTs brands available in South America from three companies, Rapigen (South Korea), SD-Biosensor (South Korea), and Certest (Spain), compared to the gold standard RT-qPCR. A total number of 1,646 nasopharyngeal swabs from community-dwelling individuals were included in the study, and 379 of them were SARS-CoV-2 positive by RT-qPCR. The overall sensitivity for each RDAgT was 79% (IC95%: 72 - 86.2), 64.2% (IC95%: 56.7 - 71.6), and 45.8% (IC95%: 35.8 - 55.8) for SD-Biosensor, Certest, and Rapigen, respectively. The overall specificity for each RDAgT was 100%, 97.7% (IC95%: 96.8 - 98.6), and 100% for SD-Biosensor, Certest, and Rapigen, respectively. However, the limit of detection (LoD) to achieve a sensitivity over 90% was substantially lower for Certest RDAgT (102 copies/uL) compared to SD-Biosensor (103 copies/uL) or Rapigen (106 copies/uL) RDAgTs, considering that the gold standard RT-qPCR method used in this study has a high sensitivity of 97.7% and low LoD of 5 copies/uL. Additionally, the Certest RDAgT also showed an improved sensitivity up to 79.7% (IC95%: 70.2 – 89.2) for symptomatic individuals. Finally, the slight reduction in specificity for Certest RDAgTs was only associated with one of the laboratories performing this study, pointing out the need for locally assessed evaluation for RDAgTs like this one carried out in Ecuador. In conclusion, two of the three the RDAgTs tested in this study are a fast, cheap, and point of care tool for SARS-CoV-2 surveillance and reliable enough to detect SARS-CoV-2 infectious individuals.

Apart from other risk factors, chronic inflammation is also associated with the onset of Prostate Cancer (PCa), wherein pathogen infection and tissue microbiome dysbiosis are known to play a major role in both inflammatory response and cancer development. However, except for a few studies, the link between microbes and PCa remained poorly understood. To explore the potential microbiome signature associated with PCa in Indian patients, we investigated differential compositions of commensal bacteria among patients with benign prostatic hyperplasia (BPH) and PCa using 16S rRNA amplicon sequencing followed by qPCR analyses using two distinct primer sets. Using two independent cohorts, we show that Prevotella copri, Cupriavidus campinensis, and Propionibacterium acnes represent the three most abundant bacteria in diseased prostate lesions. LEfSe analyses identified that while Cupriavidus taiwanensis and Methylobacterium organophilum are distinctly elevated in PCa samples, Kocuria palustris and Cellvibrio mixtus are significantly enriched in BPH samples. Furthermore, we identify that a number of human tumor viruses, including Epstein-Barr virus (EBV) and hepatitis B virus (HBV), along with two high-risk human papillomaviruses - HPV-16 and HPV-18, are significantly associated with the PCa development and strongly correlated with PCa bacterial signature. The study may thus offer to develop a framework for exploiting this microbial signature for early diagnosis and prognosis of PCa development.
Evaluation of the Effect of Gene Duplication by Genome Editing on Drug Resistance in Plasmodium falciparum

Published: July 2022

The emergence and spread of drug-resistant Plasmodium falciparum have compromised antimalarial efficacy and threatened the global malaria elimination campaign using artemisinin combination therapies. The impacts of amino acid substitutions in antimalarial drug resistance-associated genes on drug susceptibility have been investigated; however, the effects of amplification of those genes remain unexplored due to the lack of robust genetic approaches. Here, we generated transgenic P. falciparum parasites with an additional copy of a drug resistance-associated gene using the highly efficient CRISPR/Cas9 system and investigated their drug response. Insertion of a drug resistance-associated gene expression cassette in the genome resulted in a roughly twofold increase of mRNA levels of the target gene mdr1, which encodes multidrug resistance protein 1. The gene duplication event contributed to resistance to mefloquine, lumefantrine, and dihydroartemisinin, while the duplication of a genomic region encoding plasmepsin 2 and plasmepsin 3 did not affect resistance to antimalarial drugs, including piperaquine. We further demonstrated that mdr1 mRNA expression levels are strongly associated with mefloquine resistance in several field-derived P. falciparum lines with various genetic backgrounds. This study provides compelling evidence that mdr1 could serve as a molecular marker for the surveillance of mefloquine-resistant parasites. Long DNA integration into parasite genomes using the CRISPR/Cas9 system provides a useful tool for the evaluation of the effect of copy number variation on drug response.
