The development of the world community occurs so quickly and so unevenly that it is too difficult to monitor the changes taking place in it, and even more so to study and take into account in practical application. Without such monitoring of changes in social development, and even more so in its main component – the economy, it is impossible to understand the consequences of the changes themselves and the direction of further development. The changes at the global level that are taking place in our time also require a detailed study and the immediate implementation of the obtained results in the economic process in order not to be aloof from these changes and not to lose their place in the already occupied niche of economic development. In these conditions, there are several priorities for the study of the current economic situation: one of the first priorities is the development of the agricultural sector with climatic and migration changes, the production of alternative energy sources, changes in preferences in people’s nutrition priorities, etc.; the following: rather high competitiveness among manufacturers, which prompts them to reduce the price of products (not always to the benefit of consumers in terms of quality characteristics); the delivery routes of all types of products, already established for decades, were disrupted by the unexpected impact of the COVID-19 pandemic, and later also by military actions on the territory of Ukraine. These factors have had a significant impact on global markets and should be studied by both scientists and practitioners to find new ways, methods, and tools for managing logistics supply chains, using effective competitive measures, first, with the involvement of developments in the field of digitization of processes. Innovative processes should play a special role in this direction, because only thanks to innovations and innovative technologies it is possible to quickly and effectively level the situation and avoid unpredictable negative consequences of the influence of today's challenges.

Published: March 2023

The rapid growth of the population and the consequent increase in migration to the cities during the past decades have caused the expansion of many urban areas. In this study, the growth and development of the urban areas of Al-Diwaniyeh during the recent decades using three categories: 1. urban limits layer extracted from land use maps during the period, 2. population density layers and 3. Degree of urbanization in the period 1975 to 2015 It was investigated, monitored and modeled. Modeling and forecasting for the future was done using layers of population density and degree of urbanization. The population density map for 2025 was implemented based on population changes in the last two decades using the multilayer artificial neural network method. While the prediction of the degree of urbanization was operationalized by creating and applying a multi-layer neural network model for 2030. The results of the study showed that the general trend of the expansion of Al-Diwaniye city limits during the period of 1975 to 205 was increasing. The degree of urbanization in Al Diwaniyah has been increasing since 1975. After 1975, the initial cores of the dense areas were formed, and gradually, in the following periods, the expansion of the urban areas of Al-Diwaniyeh was observed around the cores. The class of rural areas has shown an upward trend with a more uniform slope compared to other classes of the degree of urbanization. While after 1990, high density and low density classes with close areas have also gone through an upward trend. The rate of population density and, accordingly, the rate of population in Al-Diwaniye has been increasing between 1975 and 2015. The trend of maximum population changes has been downward; therefore, it can be claimed that the initial dense cores of the urban population of Al-Diwaniyeh have moved to the surrounding areas. In the estimated degree of urbanization in 2030, the class with high density has faced a decrease in area compared to the previous period. In general, the area of ​​built-up areas in 2030 will increase compared to previous periods, but this will be achieved with a slower acceleration and slope compared to previous periods.

Background: Portunus pelagicus crab species meat is generally taken, and their shells that is thrown away becoming untapped waste. Their shells contain so many useful minerals such as calcium carbonate ­which can be processed into hydroxyapatite (HA). HA has been extensively used in the medical field for bone grafting, to repair damaged in bone structures. Purpose: To determine the biocompatibility of hydroxyapatite from Portunus pelagicus crab’s shells extract after sterilized using UV on human gingival fibroblast cell. Methods: This research is an experimental laboratory research using post-test only control group design. The shells were first heated using furnace. Once hydroxyapatite was obtained, it was sterilized using ultraviolet (UV) with certain concentration (25 ppm, 50 ppm, and 100 ppm) to kill the microorganisms. MTT assay was done to test the biocompatibility of the sterilized hydroxyapatite on human gingival fibroblast cell. Results: The highest viability of fibroblast cells was the group with 50 ppm UV (98.10%), followed by 100 ppm UV (97.93%), and 25 ppm (93.28%). Conclusion: Hydroxyapatite from Portunus pelagicus crab’s shells extract sterilized using UV is biocompatible towards human gingival fibroblast cell.
Identification of Polymerase and Proofreading Exonuclease Domains in the DNA Polymerases IA, IB and Nuclear-Encoded RNA Polymerase of the Plant Chloroplasts
Authors: Peramachi Palanivelu
Published: March 2023

Chloroplast plays a crucial role in all photosynthetic plants and converts the light energy to chemical energy. It is a semi-autonomous organelle and is mostly controlled by its own genome and partly by the nuclear imports. To replicate its own genome, it uses two DNA polymerases, viz. polymerases IA and IB. DNA polymerase IA showed 72.45% identity to polymerase IB, but only 35.35% identity to the E. coli DNA polymerase I. Multiple sequence alignment (MSA) analysis have shown that the DNA polymerases IA and IB and the E. coli DNA polymerase I possess almost identical active sites for polymerization and proofreading (PR) functions, suggesting their possible common evolutionary origin. The nuclear-encoded RNA polymerase (NEP) is imported from the nucleus and involves in the transcription of all the four subunits of the chloroplast RNA polymerase. The polymerase catalytic core of the DNA polymerases IA, IB and the NEP are remarkably conserved and is in close agreement with other DNA/RNA polymerases reported already, and possess a typical template-binding pair (-YG-), a basic catalytic amino acid (K) to initiate catalysis and a basic nucleotide selection amino acid R at -4 from K. The DNA polymerases IA and IB are very similar to prokaryotic DNA polymerases, except in possessing a zinc-binding motif (ZBM) in them, like the eukaryotic replicases. Interestingly, the PR exonucleases of all three polymerases belong to the DEDD-superfamily of exonucleases. The DNA polymerases IA and IB belong to the DEDD(Y)-subfamily, whereas the NEP belongs to the DEDD(H)-subfamily.

Published: March 2023

В настоящее время обеспечение населения России свежими овощами в течение всего года невозможно без развития овощеводства закрытого грунта. В теплицах томаты зачастую подвергаются стрессовым факторам. Это влияет не только на вкусовые качества, но и на завязываемость плодов. Изучено влияние препарата, содержащего раствор ауксинов, на устойчивость к биотическим стрессовым факторам и продуктивность растений томата в условиях пленочной весенней необогреваемой теплицы с боковой и коньковой вентиляцией в условиях Краснодарского края. Объектом исследования послужила селекционная линия салатного направления. Установлено, что при выращивании растений томата на среднем агрофоне в пленочных необогреваемых теплицах при стрессовых температурах применение препарата Преауксил 101 оказывает положительное действие на увеличение завязавшихся плодов (на 31,37 %), что повышает общую продуктивность растений. Наблюдается более дружная отдача сортом раннего урожая на 47,5 %. Сокращается межфазный период «всходы – начало цветения» на 5 дней и «завязывания плодов – начало созревания» на 9 дней, что дает возможность получения более ранней продукции.

Environmental Features of Vernacular Architecture: The Case of Cyprus
Authors: Philokyprou Maria
Published: March 2023

The sustainability of vernacular dwellings is closely connected with the fulfilment of the daily needs of the inhabitants, as well as the incorporation of multiple environmental features into their design. These environmental features ensure a climate responsive approach and improve the thermal performance of the dwellings. The vernacular architecture of Cyprus follows the main principles of vernacular architecture in the eastern Mediterranean region as a whole, and thus it is considered as a typical case study, suitable for in-depth investigation. The research findings presented here are an overview of systematic research carried out over the last ten years at the University of Cyprus, mainly through two multidisciplinary research programmes. Specifically, various environmental aspects were thoroughly investigated, starting from the selection and investigation of rural and urban settlements in different climatic areas (urban scale), moving to the building scale and to the selection of a representative number of vernacular dwellings for qualitative, as well as quantitative investigation. Following this, the research focuses on the different spaces within the dwellings (such as courtyards, semi-open spaces and subterranean areas), as well as on various passive strategies (such as ventilation and lighting), ending with the investigation of the thermal behaviour of the traditional building materials used for the erection of the aforementioned dwellings. The research reveals the necessity for a qualitative and quantitative assessment of vernacular architecture through a multicriteria process, and indicates a methodology that can be implemented in other similar cases especially around the Mediterranean area.

Published: March 2023

This study aims to explore whether, the teaching methodologies deployedin private schools in Islamabad are confining children (between the agesof 3-12 years) to polarized gender identities? This question of children’sgendering becomes pertinent when we explore the implications of raisingchildren in gender confined environments. This research will analyze themechanisms deployed in private Montessori/Kindergarten and elementaryschools in Islamabad from feminist perspective. For this purpose,qualitative method research will be used, and we will conduct semistructured interviews with fifteen school teachers of five private schoolsbased in Islamabad. This particular category of schools has been chosenbecause these schools draw their teaching methodology and curriculumfrom the American and British systems of education. Based on thispremise these schools claim to be progressive and forward looking in theirscope to education and child development. Moreover, these privateschools are engaged with different international syllabi and techniques toengage the students of diverse socio-economic class backgrounds. Basedon this premise these schools claim to be progressive and forward lookingin their scope to education and child development. However, given thelack of attention to social learning in schools this study aims to find outwhether such ‘modernist’ schools are also blinded by the concerns forraising children in gender discriminatory environments. The paper aims toestablish that if gender binaries are transmitted to children through earlyyears schooling then what consequences does that instill on the childrenfrom the feminist standpoint. But the question that how and whetherchildren can be trained in schools to live beyond gendered binaries arebeyond the scope of this paper.

Published: March 2023

Autism is a neuro developmental disorder, that is associated with social and interactive abnormalities and with other language impairments. Language learning is related to the embodiment and acquisition of thelinguistic concepts depends on the socio-physical experiences. Studies have also approved that assisted or scaffolding learning can also help in language learning and acquisition. The present research studied the role of scaffolding learning in autistic children. The level of the lexical concepts of autistic children was observed in pre and post experiment. Children were taughtthe concept of birthday party event with the help of video and pictures. Theresults showed significant improvement in the acquisition of the concept of nouns; however, they were lagging in acquiring the concept of verbs related to the event of birthday party. It is assumed that visual experience helped the children in acquiring the nouns but no experience of performing the action can be the reason for the poor acquisition of verbs.

These nutritional substances and the quality characteristics of the egg are affected by the physicochemical changes with the effect of various factors during storage. Different studies have been carried out to preserve the quality values of eggs during storage. In these studies, Ultraviolet applications were mostly used for the sanitation of eggs, while Ultraviolet applications were made to determine the internal quality of the egg without breaking the shell. The aim of this study is to determine the effects of ultraviolet and ultrasound applications applied before storage to the quality characteristics of the eggs collected from laying hens. Eggs collected in the morning were subjected to ultraviolet and ultrasound treatments before storage and stored for 28 days in an environment of 20°C and approximately 60% humidity. The applied treatments made a significant difference between the groups in egg shell thickness (p <0.01), albumen weight (p <0.01) and yolk dry matter value (p <0.01). Storage time, on the other hand, made significant changes between groups on weight loss, shell breaking strength, albumen and yolk quality characteristics. The interaction of applications and storage time was statistically significantly in weight and height of albumen, Haugh unit and dry matter of yolk. As a result, the effects of processes such as ultraviolet and ultrasound applied to eggs, especially on egg shell thickness, reveal the importance of application time and application amount in such studies.

Objetivo: Tradução e validação da versão breve do Inventário de Flexibilidade Psicológica Multidimensional (MPFI-24) para a população portuguesa. Métodos: A amostra foi constituída por 650 participantes, com idades entre os 18 e os 74 anos. Os participantes preencheram um protocolo online composto por um questionário sociodemográfico, o Multidimensional Psychological Flexibility Inventory-24 (MPFI-24), a Psy-Flex, o Patient Health Questionnaire-4 (PHQ-4) e o Mental Health Continuum-Short Form (MHC-SF). Resultados: A análise fatorial confirmatória do MPFI-24 mostrou a plausabilidade do modelo de dois fatores de ordem superior com seis fatores de primeira ordem de Flexibilidade Psicológica (FP) e seis fatores de primeira ordem de Inflexibilidade Psicológica (IP). O MPFI-24 mostrou uma adequada fidedignidade, com valores alfa superiores a 0,70 nos índices globais e em todos os fatores. Revelou ainda uma boa estabilidade temporal. A FP mostrou uma associação positiva com a flexibilidade psicológica, avaliada pela Psy-Flex e com a perceção de saúde mental (MHC-SF) e uma associação negativa com estados emocionais negativos (PHQ-4). A IP revelou o padrão oposto, sendo todas as correlações moderadas e significativas. A idade mostrou uma associação positiva com a FP e negativa com a IP. Não foram encontradas diferenças de género para os dois indicadores globais. Conclusões: O MPFI-24 demonstrou ser um inventário válido e fidedigno para avaliar a FP e IP em adultos da população portuguesa. Este instrumento pode ser utilizado em contexto clínico e de investigação, sendo um contributo relevante na avaliação de intervenções que visam aumentar a flexibilidade psicológica.

This report summarizes vaccination rates in the United States and compares estimates of vaccination rates from the COVID States Project (CSP), the Kaiser Family Foundation (KFF), and the Centers for Disease Control (CDC).● Vaccination rates for the primary series of vaccinations have plateaued since the Fall of 2021.● The regions with the highest vaccination rates are the Northeast and the West Coast plus Hawaii. The regions with the lowest rates are the South, and a block of adjacent states in the upper West/Midwest (the Dakotas, Montana, Wyoming, and Idaho)● Less than a third of respondents report getting the bivalent booster, with majorities in every state reporting not getting the bivalent booster.● CDC data deviate quite substantially from survey-based measures (CSP and KFF) of vaccination rates. These deviations almost certainly reflect errors in the underlying official records used by the CDC, driven by the inability of states to link records of multiple shots to a given individual. Official data thus offer a distorted picture of the trends in vaccination rates in the country, and where those distortions have grown over time.
Rise and fall of Caribbean mangroves
Authors: Rull Valentí
Published: March 2023

Mangrove forests, which are essential for the maintenance of terrestrial and marine biodiversity on tropical coasts and constitute the main blue-carbon ecosystems for the mitigation of global warming, are among the world’s most threatened ecosystems. Mangrove conservation can greatly benefit from paleoecological and evolutionary studies, as past analogs documenting the responses of these ecosystems to environmental drivers such as climate change, sea level shifts and anthropogenic pressure. A database (CARMA) encompassing nearly all studies on mangroves from the Caribbean region, one of the main mangrove biodiversity hotspots, and their response to past environmental shifts has recently been assembled and analyzed. The dataset contains over 140 sites and ranges from the Late Cretaceous to the present. The Caribbean was the cradle of Neotropical mangroves, where they emerged in the Middle Eocene (~50 million years ago; Ma). A major evolutionary turnover occurred in the Eocene/Oligocene transition (34 Ma) that set the bases for the shaping of modern-like mangroves. However, the diversification of these communities leading to their extant composition did not occur until the Pliocene (~5 Ma). The Pleistocene (the last 2.6 Ma) glacial-interglacial cycles caused spatial and compositional reorganization with no further evolution. Human pressure on Caribbean mangroves increased in the Middle Holocene (~6000 years ago), when pre-Columbian societies began to clear these forests for cultivation. In recent decades, deforestation has significantly reduced Caribbean mangrove cover and it has been estimated that, if urgent and effective conservation actions are not undertaken, these 50 million-year-old ecosystems might disappear in a few centuries. A number of specific conservation and restoration applications based on the results of paleoecological and evolutionary studies are suggested.

DataPipe (https://pipe.jspsych.org) is a tool that allows researchers to save data from a behavioral experiment directly to the Open Science Framework. Researchers can configure experiments on the DataPipe website and then use the DataPipe API from any internet-connected experiment. DataPipe is free to use and open-source. This paper describes the design of DataPipe and how it can help researchers adopt the practice of born-open data collection.
How scientists can optimise their impact on pressing societal problems: Commentary on Chater and Loewenstein (2022)’s argument for research on systemic change

Published: March 2023

In a recent contribution to Brain and Behavioral Sciences, Chater and Loewenstein (2022) argue that researchers can increase their societal impact by addressing behavioural research topics relevant to systemic change (i.e., “s-frame”) rather than research on individual change (i.e., “i-frame”). By swinging the pendulum back from overly relying on i-frames, we expect their call to be influential among researchers interested in having a positive societal impact. The present commentary discusses their contributions in the light of the assertion that the cause a researcher addresses is a major determinant of the potential societal impact of research. We argue that large-scale but neglected problems can yield highly effective s- and i-frame research topics, and the distinction between i- and s-frames could yield a helpful complementary heuristic for choosing research topics that address the most pressing societal problems.
