Authors: Ernawati  , Mawardi Fitriana , Roswiyarni  , Melissa  , Wiwaha Guswan , Tiatri Sri , Hilmanto Dany
Published: May 2022

Background and objectives: This systematic review aimed to uncover the evidence and benefits of employers’ commitment to delivering workplace wellness programs for working mothers.Methods: The articles published in PubMed, Embase, Scopus, and AgeLine databases between 2017 and 2021 were searched to evaluate the workplace wellness programs for working mothers with at least one resultant wellness or wellbeing (e.g., physical health, less stress, mental health, burnout, depression, smoking, bullying, alcohol consumption, overweight), work-life balance outcome, or job satisfaction.Results: Four studies that met the criteria were retrieved from databases. They showed some effective workplace wellness programs that can reduce depression, stress, and burnout, improve mental health, healthy behaviours, work-family balance and work-life balance. Working mothers participating in a workplace wellness program generally gain some benefits; one of which is reduced stress typically related to childcare, economic, and personal health issues.Conclusions: The implementation of workplace wellness programs for working mothers showed positive effects on their health problems and health costs. These four studies revealed that workplace wellness programs specifically designed for working mothers can lead to time efficiency by holding the programs in or near the workplace and implementing them during the workdays. This greatly suits the conditions of many working mothers whose limited time and energy to balance the household, family and work tasks.

AMP-activated protein kinase (AMPK) activators can improve inflammatory pain and neuropathic pain. Inflammation translocate signal transducers and activators of transcription 3 (STAT3) to the nuclei of activated macrophages, and STAT3 phosphorylation promotes the expression of inducible nitric oxide synthetase (iNOS). We determined whether AMPK activation alleviate inflammatory pain via STAT3 nuclear translocation and phosphorylation. In this study, immunoblotting was used to measure the expression of p-AMPK, and iNOS. Immunoblotting and immunofluorescence were used to detect the nuclear translocation of p-STAT3(Ser727) and STAT3 in macrophages of local inflammatory tissues. Flow cytometry was used to measure reactive oxygen species (ROS) accumulation and mitochondrial damage. AMPK activation with AICAR significantly alleviated pain hypersensitivity and inhibited the expression of iNOS in complete Freund's adjust (CFA)-induced inflamed skin tissues. CFA caused nuclear translocation of STAT3 and p-STAT3(Ser727) in macrophages of inflamed skin tissues. AICAR inhibited nuclear translocation of STAT3 and p-STAT3(Ser727) and promoted the phosphorylation of STAT3(Ser727) in the cytoplasm of macrophages. AICAR also inhibited the expression of iNOS and nuclear translocation of STAT3 and p-STAT3(Ser727), and promoted the phosphorylation of STAT3(Ser727) in NR8383 macrophages treated with CFA. AMPK activation also inhibited the ROS generation and the mitochondrial damage of NR8383 macrophages caused by CFA. In addition, transfection of STAT3 S727D decreased ROS and alleviated mitochondrial damage. In conclusion, Activation of AMPK attenuates inflammatory pain and suppresses STAT3 nuclear translocation and phosphorylation of STAT3(Ser727) in macrophages, resulting in reduced iNOS. Activation of AMPK also promotes phosphorylation of STAT3(Ser727) in the cytoplasm of macrophages to alleviate ROS accumulation and mitochondrial damage associated with inflammation.

Authors: Popko Svitlana , Aksamytieva Mariya
Published: May 2022

The present study was aimed to evaluate the possibility of using anti-human monoclonal antibody CD3 as pan T-cell marker in the guinea pigs’ trachea and lung in early and late manifestations of the allergic inflammatory process.

Materials and methods.We have studied the distribution and quantitative changes of CD3-positive lymphocytes in trachea and lung of guinea pigs using histological, immunohistochemical, statistical methods in conditions of experimental inflammatory process.

Results. Our results revealed the applicability of anti-Human monoclonal antibody CD3 (Clone SP7, «DAKO», Denmark) cross-reaction with T-cells of guinea pigs’ tracheas and lungs. The most statistically significant elevation of the number of CD3-positive lymphocytes, in comparison with the control group (p*/**<0.05), observed in the experimental group III in the late stages of experimental inflammatory process. The elevation of the number of CD3-positive lymphocytes persists even after the termination of the allergen action, which indicates the continuation of the reaction of pulmonary local adaptive immunity to the allergen.

Conclusions. The results of our study may be useful in conditions of the deficiency of guinea pig-specific tests. The immunohistochemical assessment of guinea pigs’ trachea and lungs proved the possibility to use anti-Human monoclonal antibody CD3 as a panT-cell marker in guinea pigs. We demonstrated the activation of adaptive immune response (T-cells), represented by their immunohistochemical changes, predominantly in the late stages of experimental inflammatory process.

Authors: Gnanasundar V.
Published: May 2022

Abstract. Conventional concrete has a low tensile strength, constrained ductility and little protection from crack propagation. The inward miniaturized scale of cracks, prompting weak disappointment of concrete. Investigations have been carried out in many countries on various mechanical properties, physical performance and durability of cement-based matrices reinforced with naturally occurring fibers including sisal, coconut, jute, bamboo, and wood fibers. Raised natural mindfulness and an expanding worry with an unnatural weather change have invigorated the search for materials that can supplant traditional engineered fiber. Characteristic fiber, for example, sisal strands show up as one of the great options since they are accessible in sinewy structure and can be separated from plant leaves, stalk, and products of the soil at exceptionally low expenses. In this work, the impact of sisal strands on the quality of cement for M25 evaluation has been examined by shifting the level of filaments in concrete. Fiber substance were shifted by 0.05%, 0.10%, 0.15%, 0.20%, 0.25%, 0.30%, 0.35% and 0.40% by volume of cement. Cubes, Cylinder and Prism were cast to assess the Compressive, Split Tensile and Flexural Strength test. Every one of the samples was tested for a time of 28 days curing. The results of fiber reinforced concrete for 28 days curing with a varied percentage of fiber were studied and it has been found that there is significant strength improvement with addition of sisal fiber in concrete.

Published: May 2022

Abstract. Clay soil is usually stiff in dry state, but in wet state, it loses its stiffness and becomes softer. Various types of clay minerals have unique characteristics of low bearing capacity and certain compressibility. Especially Montmorillonite clay mineral exhibits more degree of swelling and shrinkage and loss of strength when moisture added. According to recent research, rice husk ash is a potential improving material based on its pozzolanic activity. In this study, to improve the engineering properties of expansive clay the admixture such as fly ash and rice husk ash will be added in different percentages as 5, 10, 15 and 20. For the laboratory test that includes atterberg’s limits test, standard proctor compaction test and unconfined compression test were conducted on locally collected expansive soil with various percentages of these two stabilizers in order to examine their influences. The maximum values of Unconfined Compressive Strength were obtained corresponding to 15% Rice Husk Ash and 20% Fly ash.

Authors: Indhu M.P.
Published: May 2022

Abstract. Additives are ingredients and chemicals that are mixed into concrete to improve its fresh state and change its properties. The majority of admixtures are sold as chemical compositions on the market. These chemical admixtures are exceedingly costly and harm the environment significantly. Adding admixtures to concrete, on the other hand, is not a new notion; it has been used and developed in numerous countries in the past. In this project, we are investigating the possibilities of using natural materials like "Terminaliachebula” (Kadukkai). Terminalia chebula extract is added in different concentrations of 2.5%, 5%, 7.5% to the cement concrete, and its effects on the workability and strength of concrete are studied. Terminalia chebula when added to cement mortar does not affect however, it improves workability while also increasing compressive strength by 1.832 times of reference concrete. But the initial setting time of concrete is increased by 30 minutes of nominal OPC concrete.

Published: May 2022

Abstract. In the latest period, the volume of building material has greatly extended, raising social and environmental concerns surrounding waste recycling. Construction and demolition waste is a significant factor in global generated waste. Construction necessarily requires the use of massive quantities of aggregates. When the structure's useful life is up, it will be demolished, and all of the demolished waste will disposed of in landfills. It became increasingly difficult to identify large areas for landfills. Crushed, graded inorganic particles that have been processed from construction materials and demolition debris make up recycled aggregates. Aggregates that have been recycled for use in high-strength structural concrete. In this work, recycled coarse aggregate was employed to replace virgin coarse aggregate. The properties of both fresh and hardened concrete made from 100 % recycled coarse aggregate which has been internally or externally replaced found, and the effects are compared to concrete by applying the virgin coarse aggregate.

Published: May 2022

The analysis of air quality is directly related to the health preservation of individuals who attend closed environments, climatized or not, and this factor can be linked to the place (un)salubrity. Certain polluting factors are potentiated by the lack of natural ventilation; in other cases, depending on the region, the natural circulation of wind is what brings pollution to the place. Considering that all environments can be affected by a sanitary decrease promoted by low air quality, the present work aims to analyze the air contamination indices of the Forum Lourenço José Ribeiro, located in the municipality of Olinda/PE. The methodology uses exploratory research in a case study to be carried out by obtaining quantitative data on carbon dioxide (CO2) indices, internal temperature and relative air humidity that were measured between february and june/2021, in the morning shift of the aforementioned building. The present work is limited to the breadth of the data to be researched, and it should also be considered that the researched period faced the limitation of face-to-face activities motivated by the Coronavirus pandemic, which substantially reduced the amount of exposed and polluting people in the premises Results obtained indicate a good indoor air quality in the evaluated rooms, both for users, servers and occupants of sealed and artificially air-conditioned spaces, with good air renewal. Future work should be guided by the search for solutions capable of improving the natural ventilation of the researched environments, in addition to research carried out during the face-to-face working hours of the servers of the Forum Lourenço José Ribeiro.

Occidente vs Oriente: factores cívico-políticos que conducen a resultados diferenciados frente al SARSCoV2
Authors: Añorve Añorve Daniel , Rosas González María Cristina
Published: May 2022

Los impactos por el SARSCoV2 han sido diferenciados geográficamente. En términos generales, las mayores tasas de contagios, decesos y letalidad tienen lugar en Occidente en oposición con lo observado en Oriente. Se aborda la pandemia desde la cultura cívico-política a partir del predominio que el individuo tiene en las naciones occidentales frente a la relevancia que posee la colectividad/comunidad en las orientales. Se analizan 11 países conforme a la tipología de Samuel Huntington: cuatro occidentales, cinco países no-occidentales y dos países escindidos o híbridos. Se sugiere que los países donde las libertades cívico-políticas en torno a la colectividad predominan, han tenido una menor incidencia de contagios/decesos durante la actual pandemia El análisis revela la importancia de la cultura cívico-política para hacer frente a emergencias como la pandemia del SARSCoV2.
Machine Learning System for Malicious Website Detection using Concept Drift Detection

Published: May 2022

Abstract: The rampant increase in the number of available cyber attack vectors and the frequency of cyber attacks necessitates the implementation of robust cybersecuritysystems. Malicious websites are a significant threat to cybersecurity. Miscreants and hackers use malicious websites for illegal activities such as disrupting the functioning of the systems by implanting malware, gaining unauthorized access to systems, or illegally collecting personal information. We propose and implement an approach for classifying malicious and benign websites given their Uniform Resource Locator(URL) as input. Using the URL provided by the user, we collect Lexical, Host-Based, and Content-Based features for the website. These features are fed into a supervised Machine Learning algorithm as input that classifies the URL as malicious or benign. The models are trained on a dataset consisting of multiple malicious and benign URLs. We have evaluated the accuracy of classification for Random forests, Gradient Boosted Decision Trees and Deep Neural Network classifiers. One loophole in the use of Machine learning for detection is the availability of the same training data to the attackers. This data is exploited by the miscreants to alter the features associated with the Malicious URLs, which will be classified as benign by the supervised learning algorithms. Further, owing to the dynamic nature of the malicious websites, we also propose a paradigm for detecting and countering these manually induced concept drifts.

Indonesia considers predicate crime in the category of ordinary crime consisting of fraud and embezzlement. However, ordinary or conventional crimes may only be subject to the Law under limited circumstances. Article 69 of the Law of Money Laundering remains debatable among criminal law experts due to the relation with Articles 77 and 78 of the Law. The last two articles prescribe that burden of proof on the case of predicate crimes is on defendant, not public prosecutor. Defendant must prove assets that are suspected as result of crime, not acquired from the crime, or related to crime. Currently, there is no elucidation to the articles. This study analyzed two legal issues. Firstly, does the formulation of Article 2, paragraph 1, and Article 69 of the Law of Anti-Money Laundering guarantee legal certainty and fulfil a sense of justice? Secondly, does the Article 2 paragraph 1 letter z of the Law cause ordinary criminal acts to be entangled with the Law on Money Laundering?
Life strategies of the far-eastern youth

Formation of the life strategies of young people is influenced by many factors, among which one of the most influential is regional specificity. The subjects of the Far-Eastern federal district have a number of features that predetermine special approach to their development, declared a national priority of the XXI century, and create a request for preservation and development of human capital in the regions. Youth is the labor and population potential of the Far-Eastern region, on which the effective development of the territory largely depends. In this regard, life strategies of the Far-Eastern youth are of particular research interest, including in order to prevent the emergence of migration moods of young people. Analysis presented in the article is based on the results of a sociological study conducted among young people living in the border regions of the Far-Eastern federal district. The results of analysis showed that young people find opportunities to implement the strategy of life well-being, the strategy of life success, family self-realization, including outside the Russian borders, including in China. Desire of a number of young Far-Easterners to leave the country temporarily (for the period of study) or for permanent residence is caused, in their opinion, by insufficient opportunities for self-realization and realization of their life plans in the Far East. The study confirms that the frontier factor has a direct impact on formation of life strategies of the Far-Eastern youth along with the others. Existence of a request for preservation and consolidation of the indigenous population in the Far East as a necessary condition for its effective development requires study and understanding of this contradiction in order to find productive solutions implemented, including in the regional youth policy.
Housing affordability in the Khabarovsk territory in the context of implementation of the national project «Housing and Urban Environment»
Authors:   the Pacific State University, Stroeva G.N.
Published: May 2022

The incessant outflow of population to the western regions of the country threatens the fulfillment of the tasks of socio-economic development of the Khabarovsk territory. Affordability of housing is one of the main factors for securing the population in the region. Therefore, for the Khabarovsk Territory, solving the problem of affordability of housing is of particular importance. The level of provision of the population with housing and its availability for acquisition of ownership are indicators of the level of well-being of the population, its social security and investment activity. The article presents various approaches to the definition of the concept of «housing affordability». Analysis of the state of housing stock and provision of housing for the population of the Khabarovsk territory is made. The assessment of housing affordability for population was carried out using the housing affordability coefficients calculated using two methods. The results of implementation of the national project «Housing and the urban environment» and the state program «Development of housing construction in the Khabarovsk territory» are considered. It has been established that not all planned indicators of the state program in 2018-2020 have been achieved. In conditions of limited supply and failure to fulfill plans for the volume of housing commissioning, the increase in demand for housing in the primary market, caused by implementation of the Far-Eastern mortgage program, led to a significant increase in housing prices. The growth rates of housing prices outstrip the growth rates of both average wages and average per capita money incomes of the population. Therefore, a significant part of the region's population is experiencing serious difficulties in acquiring housing. To solve the identified problems, it is necessary to develop additional measures both at the federal and regional levels. Recommendations are given to improve the housing affordability in the Khabarovsk territory.

AS MEDIDAS DA POLÍTICA COMERCIAL E O INCENTIVO DA PRODUÇÃO NO SETOR DE CARNE DE FRANGO NO MERCADO MOÇAMBICANO NO PERÍODO 2010-2020
Authors: Simbine Rodrigues Almeida , Lampião Odibar João , Simione Albino Alves
Published: May 2022

Este estudo buscou refletir sobre o uso de medidas da política comercial como mecanismo visando o aumento da produção no setor de carne de frango em Moçambique. Fundamentou-se numa abordagem qualitativa com cunho descritivo. Apoiou-se igualmente na pesquisa bibliográfica, pretendendo apresentar a relevância da utilização das barreiras tarifárias e não-tarifárias pelos governos como instrumentos de política comercial para restringirem a concorrência de produtos importados face aos localmente produzidos, e sistematizar o percurso das experiências nacionais de produção no setor entre 2010-2020. Os resultados indicam uma atuação do governo e empresas produtoras proporcionando um crescimento da produção dessa proteína, cobrindo 73% da demanda interna correspondentes a 90,4 mil toneladas no último ano considerado no estudo. Apesar disso, existem potencialidades ainda pouco exploradas, capazes de melhor estruturar o mercado nacional e reduzir os índices de importação e frear o contrabando, fatores que interferem na competitividade e rápido desenvolvimento do setor.

Published: May 2022

To identify candidate pathogenic genes of early-stage Crohn’s disease
(CD) and predict potential roles of genetic factors in CD, we performed
whole exome sequencing on a child with early-stage Crohn’s disease (CD)
and her parents (core family), found that the patient carried
heterozygous variants of 4 genes: NOD2 c. 2257 C>T,
IL10RA c. 301 C>T, PLA2G6 c. 2029
C>T, COL7A1 c. 3190 G>A. With joint
action of NOD2, IL10RA, PLA2G6 and COL7A1,
excessive intestinal inflammatory response is triggered, resulting in
normal intestinal wall tissue damage. Meanwhile, intestinal wall tissue
repair is impaired, aggravating inflammation and injury, and leading to
severe CD phenotype.

Abstract: Caryopteris mongholica is a rare resource plant distributed in
typical steppe, desertified steppe and desert areas. Based on field
survey data sampled during the growing seasons from 2018 to 2021,
combined with relevant previous literature, this study analyzed the
distribution and environmental characteristics of C. mongholica
population, the characteristics, classification and species diversity of
C. mongholica community, and the influence of environmental factors. The
results showed that: (1)The C. mongholic population was mainly
distributed in the east, middle and west of Inner Mongolia Autonomous
Region, the north of Loess Plateau, Hexi corridorm, Qilian Mountains and
other northwest temperate desert or steppe areas in China. It was the
dominant species or companion species in the community. (2) According to
the survey of 40 sample plots, a total of 141 species of seed plants
were recorded, belonging to 110 genera of 37 families, and families of
Compositae, Leguminosae and Gramineae played crucial roles in the
species composition. Among them, 42 of these species were shrubs and
dwarf/semi-shrubs, 76 were perennial herbs, 23 were annuals and
biennials. In the class of species presence, 88.02% were occasional
species with frequency distribution smaller than 20%. Typical
xerophytes occupied the main advantage(32.39%) in the water ecological
types. East Palearctic elements(25.35%) were the major floristic
geographic elements. (3) Based on the life form and dominance of
species, the C. mongholica communities were divided into 6 major
association groups,which were further divided into 23 associations.
(4)Precipitation, solar radiation and other environmental factors
significantly affect the distribution of C. mongholica population and
the species diversity of the community. Key word: Caryopteris

To fulfil the world's growing need for fossil fuel energy, renewable energy harvesting is required, and the rate of depletion of non-renewable energy sources must be slowed. Currently, many of these techniques are available, but with less effectiveness than before. These techniques result in a long payback period of investment. The goal of this research is to look at many elements of convective heat transfer enhancement using finned heat pipes, as well as the recovery of industrial waste heat. To validate these new energy-saving concepts, ANSYS 2020 R1 is used, including control strategies and simulation techniques. An integrated waste heat recovery system using finned heat pipes is having a significant effect on overall efficiency. The efficiency is increased by 10.5%–18.8% for various load conditions.

Published: May 2022

Oil methanolysis over modified CaO catalysts was studied to assess the catalytic performance and to define an appropriate kinetic model. CaO was modified by commercial glycerol and a deep eutectic solvent (DES), choline chloride : glycerol (ChCl : Gly), to obtain catalytically active complexes of CaO and glycerol. The main goal was to investigate the effect of the obtained complexes on the reaction rate and fatty acid methyl ester (FAME) content and to describe the variation of the triacylglycerol (TAG) conversion degree during the reaction time. Fourier transform infrared spectroscopy (FTIR) was applied to confirm the formation of CaO complexes with glycerol or the glycerol-based DES. Different catalyst loadings (0.5, 1, and 5 % of oil weight) and methanol-to-oil molar ratios (6 : 1 and 12 : 1) were applied for investigation of the sunflower oil methanolysis at 60 oC. Two kinetic models were employed yielding the kinetic parameters, which depended on the catalyst loading and the methanol-to-oil molar ratio. Both models showed valid applicability for describing the kinetics of the reactions catalyzed by both complexes (the mean relative percent deviation was lower than 10 %).
The Universe in the form of a Vortex Thor does not Need Dark Energy (Brief Concept “Ode to the Universe” - New Theory of the Structure of the Universe, Part One: The Universe)
Authors: N Lutsenko
Published: May 2022

A new model of the structure of the Universe in the form of a vortex torus has been proposed. • Equations were obtained for the dependence of the change in the volume of space, the dependence of the rate of change in the volume and the dependence of the acceleration / deceleration of the change in the volume of the space of the vortex torus, depending on the parametric angle of its generating circle. • A number of observational cosmic facts that have not been explained within the framework of the existing standard cosmological model have been verified for their full compliance with the proposed New Model of the Universe in the form of a vortex torus. • For the first time, an explanation of some unsolved space problems was obtained using a single model, i.e. proof “from one place”, without darning existing standard theories and without attracting additional new ad hoc hypotheses to replace the old ones that do not work. • A new concept of the accelerated expansion of the Universe was presented. • It is shown why the currently observed accelerated expansion of space is cyclical and not constant. • The riddle of Dark Energy has been solved: the reason for the accelerated expansion of the space of the Universe in the form of a vortex torus has been found, due exclusively to its topology, which does not require the presence of any physical forces, neither known nor hypothetical! • The explanation of the phenomenon of “dark energy” gives good grounds for the reformation of the Big Bang hypothesis and for the emergence of cosmological science from the systemic crisis. • Key words: crisis of cosmology, Universe, Dark Energy, vortex torus, Kashlinsky’s Dark Streams, accelerated / decelerated expansion, scientific principle.
