At present scenario, engineering renewable energy sources with the view of attaining maximum efficiency is more important. The current research focusses on the synthesis and deposition of molybdenum diselenide over solar cell surface for achieving maximum light transmissivity.MoSe2 nanostructures synthesised through hydrothermal method exhibit excellent antireflection property. The developed transition metal chalcogenide is pelletised and sputter coated over solar cell substrate at regular intervals. Coated samples were analysed through various characterisation techniques from which S3 sample exhibited minimum light transmittance and electrical resistivity. The MoSe2 coating with 648 nm thickness reported maximum power conversion efficiency of 19.45 %.

Macromolecules of various sizes induce crowding of the cellular environment. This crowding impacts on biochemical reactions by increasing solvent viscosity, decreasing the water‐accessible volume and altering protein shape, function, and interactions. Although mitochondria represent highly protein‐rich organelles, most of these proteins are somehow immobilized. Therefore, whether the mitochondrial matrix solvent exhibits macromolecular crowding is still unclear. Here, we demonstrate that fluorescent protein fusion peptides (AcGFP1 concatemers) in the mitochondrial matrix of HeLa cells display an elongated molecular structure and that their diffusion constant decreases with increasing molecular weight in a manner typical of macromolecular crowding. Chloramphenicol (CAP) treatment impaired mitochondrial function and reduced the number of cristae without triggering mitochondrial orthodox‐to‐condensed transition or a mitochondrial unfolded protein response. CAP‐treated cells displayed progressive concatemer immobilization with increasing molecular weight and an eightfold matrix viscosity increase, compatible with increased macromolecular crowding. These results establish that the matrix solvent exhibits macromolecular crowding in functional and dysfunctional mitochondria. Therefore, changes in matrix crowding likely affect matrix biochemical reactions in a manner depending on the molecular weight of the involved crowders and reactants.

Published: February 2023

Background: While prosthetic rings are commonly used for mitral valve repairs, autologous pericardium is an alternative ring material that can be used in these procedures. In this report, we aim to present a comparison of two types of rings used for mitral repair.
Methods: Between January 2005 and January 2009, 107 patients who underwent mitral valve repair surgery were analyzed. Patients were divided into two groups, according to the type of ring that was used for mitral annular stabilization. Glutaraldehyde-treated pericardial rings were used for 31 patients (group 1), whereas prosthetic rings were used for 76 patients (group 2). Survival, freedom from reoperation, recurrent mitral regurgitation, and the effects of rheumatic mitral disease on these parameters were evaluated and compared for both groups.
Results: Follow-up time for our cohort was 4.24±0.4 years. There were four and seven late mortalities in groups 1 and 2, respectively, and five reoperations in each group. There was no significant difference between the groups, in terms of survival, freedom from reoperation, and recurrent mitral regurgitation (log-rank analyses for both groups were P = 0.777, P = 0.346, and P = 0.781, respectively). There was no significant difference in freedom from reoperation and recurrent mitral regurgitation for both groups, in terms of underlying rheumatic valvular disease and other types of pathology.
Conclusion: Pericardial ring annuloplasty shows to be a considerable alternative technique for mitral valve repair procedures in the mid- to long-term follow up. Rheumatic mitral valves had poor outcomes, when compared with other types of structural valvular pathologies in cases where pericardial rings were used in the repair procedure.

Safe educational partnership with parents: a new integrative model of parent-teacher relationships in a diverse, polarized and changing society
Authors: Peleg Alona
Published: February 2023

During recent decades, there have been far-reaching social changes in Western countries, that have affected parent-teacher relationships dramatically. The worldwide Covid19 crisis has exacerbated educational gaps, especially among disadvantaged populations. Therefore, restoring parent-teacher relationships is a key factor in reducing inequality. However, many models of parent-teacher communication have not yet been updated to include multicultural approach or socio-systemic work. Accordingly, we propose a new integrative applicable model: safe educational partnership with parents. This model is based on cultivating psychological safety, including identity safety, as a necessary condition for building close relations. For this purpose, the teacher has to work in three levels: 1) intra-personal level 2) inter-personal level and 3) institutional-organizational level. Educators and counselors can use this model to lead protected empathetic interactions with parents and promote an environment with a perspective of "value in diversity", for the benefit of restoring trusting relationships with parents and reducing gaps.
The personalized approach to the prevention of cardiovascular diseases.
Authors:   Kharkiv National Medical University, Korzh O.M.
Published: February 2023

The article presents a number of major updates on the assessment of the risk of cardiovascular complications and the principles of preventive intervention based on the materials of the analyzed clinical recommendations. Previous European guidelines focused on risk stratification and prevention of risk factors, whereas the updated European Society of Cardiology document places great emphasis on personalization and stepwise intervention in clinical practice. When developing a prevention strategy, it is recommended to pay attention not only to gender and age indicators, but also to geographic and ethnic factors. A personalized approach to prevention using a cardiovascular risk score and stepwise selection of treatment are more complex than a general prevention strategy, but they reflect the diversity of patients and their characteristics in clinical practice.

Choosing the appropriate cosmetics is an arduous task. Because cosmetics are tested directly on the skin to ensure each personâ€™s preferences are met. The consumer repeatedly tries a sample and then discards it until he discovers one that meets his tastes. The cosmetics business and consumers are affected by this move. Companies can utilize Augmented Reality (AR) technology as an alternative to mass-producing cosmetic samples. The difficulty of deploying augmented reality is the difficulty of putting cosmetics into camera video streams. Each individual bears the burden of skin color and its effect on light. HSV Color Extraction was the method employed for this study. The application of augmented reality intends to enable consumers to test cosmetics with their chosen color and assist businesses in competing in the industry by promoting items and engaging customers. This work makes it easier to choose cosmetics using augmented reality and social media. AR simulates the usage of the desired color cosmetics, whereas social media allows users to obtain feedback on their color preferences. The outcomes of this study indicate that augmented reality (AR) apps can display filters in bright, dim, and even wholly dark lighting conditions. This research contributes originality that cosmetic firms can utilize to market their products on social media.

Published: February 2023

Abstract: Research using a simple photometric device, namely the Sky Quality Meter (SQM), is widely carried out for various purposes. Research of determining subuh prayer time using SQM in Indonesia is also widely carried out, by various groups and produces observational data from various locations. Each observation location has a different sky quality, the quality of the sky is represented by the night level obtained from observations using SQM. The beginning of subuh prayer time is obtained by determining the inflection point of the SQM data. From 460 observational data from LAPAN Pasuruan station and LAPAN Pontianak station, to determine the night level that represents the quality of the sky and the turning point solution, this research uses product moment correlation. The calculation shows that there is a correlation between the night level and the turning point solution with r = -0.77 in the strong or high correlation category, besides that the correlation pattern shows a negative correlation or reverses which indicates that the higher the night level, the deeper the turning point results. This also shows that researchers who want to make observations with SQM to determine turning points should be done in locations that have good or high night levels.
Keywords: subuh prayer time, SQM, correlation, night level, turning point.

Tiap-tiap lokasi pengamatan memilki kualitas langit berbeda, kualitas langit direpresentasikan oleh level malam yang diperoleh dari hasil pengamatan menggunakan SQM. Awal waktu subu diperoleh dengan menentukan titik belok dari data SQM. Dari 460 data pengamatan yang berasal dari stasiun LAPAN Pasuruan dan stasiun LAPAN Pontianak, untuk menentukan antara level malam yang merepresentasikan kualitas langit dengan solusi titik belok, penelitian ini menggunakan korelasi product moment. Perhitungan menunjukkan adanya korelasi antara level malam dengan solusi titik belok dengan r= -0.77 masuk pada kategori korelasi yang kuat atau tinggi, selain itu pola korelasinya menunjukkan korelasi negatif atau berbalik arah yang menunjukkan bahwa makin tinggi level malam maka hasil titik belok akan semakin dalam. Hal ini juga menunjukkan bahwa para peneliti yang ingin melakukan pengamatan dengan SQM untuk menentukan titik belok, sebaiknya dilakukan di lokas-lokasi yang memiliki level malam baik atau tinggi.

Some Escherichia coli strains harbour the pks island, a 54 kb genomic island en-coding the biosynthesis genes for a genotoxic compound named colibactin. In eukaryotic cells, colibactin can induce DNA damage, cell cycle arrest and chro-mosomal instability. Production of colibactin has been implicated in the devel-opment of colorectal cancer (CRC). In this study, we demonstrate the inhibito-ry effect of D-Serine on the expression of the pks island in both prototypic and clinically-associated colibactin-producing strains and determine the implications for cytopathic effects on host cells. We also tested a comprehensive panel of proteinogenic L-amino acids and corresponding D-enantiomers for their ability to modulate clbB transcription. Whilst several D-amino acids exhibited the abil-ity to inhibit expression of clbB, D-Serine exerted the strongest repressing ac-tivity (>3.8-fold) and thus, we focussed additional experiments on D-Serine. To investigate the cellular effect, we investigated if repression of colibactin by D-Serine could reduce the cytopathic responses normally observed during infec-tion of HeLa cells with pks+ strains. Levels of γ-H2AX (a marker of DNA double strand breaks) were reduced 2.75-fold in cells infected with D-Serine treat-ment. Moreover, exposure of pks+ E. coli to D-Serine during infection caused a reduction in cellular senescence that was observable at 72 h post infection. The recent finding of an association between pks-carrying commensal E. coli and CRC, highlights the necessity for the development of colibactin targeting thera-peutics. Here we show that D-Serine can reduce expression of colibactin, and inhibit downstream cellular cytopathy, illuminating its potential to prevent colibactin-associated disease.

In recent years, selective solar absorber surface coating applications have become quite popular in terms of enhancing the thermal performance of solar-thermal systems. Generally, nano-sized particles with high thermal conductivity values are preferred to be utilized in this type of modifications. In this study, nanoparticle-enhanced absorber coating material was applied to a quadruple-pass solar air heater to improve the thermal performance. In this regard, copper oxide nanoparticles with 38-nm average particle size and 32.9 W/m K thermal conductivity were mixed with industrial matte-black paint (2% wt./wt.). The obtained mixture was then applied to the heater and the developed heater has been experimented at three flow rate values. Embedding nanoparticles to the pure paint improved the average thermal conductivity as 0.033 W/m K (from 0.6392 W/m K to 0.6722 W/m K). According to the experimentally attained outcomes, mean thermal efficiency values were obtained in the range of 71.27-79.63%. Improving the flow rate from 0.007 kg/s to 0.013 kg/s enhanced the sustainability index value from 1.1696 to 1.2123. Moreover, maximum instantaneous thermal efficiency was found to be 4.05% higher in comparison with the system without nano-enhanced modification which was tested in a previous work.

Bast and core of kenaf which categorized as agriculture residues were used in the extraction of cellulose due to its lignocellulosic nature. In this study, cellulose was extracted from the raw kenaf by using 10% alkaline peroxide pre-treatment followed by extraction process at 85 °C using the combination of 20% (v/v) formic acid and 10% (v/v) hydrogen peroxide that formed peroxy acid. The extracted cellulose was further hydrolyzed by 1.5 M of hydrochloric acid at 80 °C to yield microcrystalline cellulose (MCC). Relatively high yield of 71.81% (w/w) and 94.8% (w/w) were achieved for extracted cellulose and MCC, respectively. Based on FESEM, the average diameter of kenaf cellulose and MCC were 12.43 μm and 11.64 μm, respectively with the separated fibrils and rod-like structural. FT-IR spectral peaks observed in the cellulose and MCC revealed that most hemicellulose and lignin were eliminated during the chemical treatments. XRD analysis results exhibited that kenaf MCC gives the sharpest and highest peak s compared to others. The results also showed that the crystallinity index of extracted cellulose and MCC were increased to 60.5% and 62.3%, respectively.

From the perspective of positive psychology, the study and measurement of subjective well-being has popularized a growing interest towards variables such as affective perception. In an attempt to explain and evaluate the affective structure in positive terms (PA) and negative terms (NA), PANASN affect scale (Sandín, 2003) constitutes the version adapted for children and teenagers of the Positive and Negative Affect Schedule (Watson et al., 1988). Opposite to the confirmatory study made in teenagers by Sandín (2003), this paper proceeds to analyse the internal structure and reliability of the above-mentioned questionnaire after being administered to 636 students aged between 6 and 14 years. An instrumental type of research methodology was carried out. The instrument used was the Positive and Negative Affect Scale for Children and Adolescents (PANASN). While confirmatory and exploratory analysis show an appropriate adjustment, these properties tend to fade when three or four factors are considered. In response to this, we reflect on the need to consider certain aspects of improvement in content and form, which are essential if we want to use said instrument with primary education students.

While global urban development is increasingly oriented towards strategies to facilitate green urbanism, potential community trade-offs are largely overlooked. This article presents the findings of a quantitative and qualitative meta-analysis of the current literature on green gentrification (the process leading the implementation of an environmental planning agenda displacing or excluding the most economically vulnerable population) in connection with climate change adaptation and mitigation across the globe. Based on specific keywords, we selected the recorded entry of 212 articles from Scopus covering the period 1977–2021. Our review focused on the historical and geographical development of the literature on urban greening and gentrification. The analysis shows that the concept of green gentrification has strong roots within the environmental justice debate in the US. In terms of intervention, most studies focused on urban parks and trees and were primarily oriented towards restoration. However, debates around the role of green facades, green roofs, or blue infrastructure (such as ponds and rivers) and other nature-based solutions as a driver for green gentrification are few and far between. Finally, we also identified a strong gap between the observation of green gentrification and potential countermeasures that respond to it. Most studies suggest that the existence of a stronger collaborative planning process within the affected communities may overcome the challenge of green gentrification. Based on our results, we identify several gaps and new research directions to design a green and just city.
