Abstract
Aim: To explore the distributed impact of Severe Mental Disorders (SMD) among people with lived experience of SMD, their family members, and community members.Methods: We conducted in-depth interviews with family key informants of people with SMD (n=32), people with SMD (schizophrenia, bipolar disorder, and major depression) (n=10), and community members (n=6) in rural Ethiopia. The study was nested within a long-standing population-based cohort of people with SMD. Interviews were conducted in Amharic and were audiotaped. We conducted thematic analysis. Results: All except one respondent described multidimensional impacts of the illness on the person with the illness, family members, and the community. We identified four themes: stress and physical tolls, lost expectations, social disruption, and economic threat.Family members reported stress and hopelessness even to the extent that they sometimes wished the individual with the illness would die; some had also tried to harm themselves. Family members reported that their relationships with each other and with the wider community were disrupted significantly. Spouses and children did not get the support they needed leading to disappointed expectations; left alone in caring for children, unable to go to school or dropping out early. The study participants with SMD also spoke about the effects of their illness on other family members and the community which appeared to be a source of shame and self-isolation. Both the family and the community respondents reported the economic effect of the illness which may result in selling assets, debt, unemployment, forced migration, and food insecurity. The community members reported the economic burden and danger related with aggressive behaviour of the person with SMD while the person with the illness and their family members blames the community for the stigma and discrimination against them. Conclusion: SMD has profound consequences on the person with the illness, their family members, and the community. Future interventions for SMD should consider household level interventions to address economic and care needs and mitigate intergenerational impact. The community should be considered as a resource as well as target for intervention.

Abstract
The current work aims to characterize silver nanoparticles/nanochitosan composite materials due to their potential industrial and biomedical applications. Chemical reduction of silver nitrate salts produced silver nanoparticles (AgNPs). LMWCS (low molecular weight chitosan) was obtained, and biodegradable chitosan was extracted from snail shells using a standard method. Sodium tripolyphosphate (TPP) was used to produce chitosan nanoparticles (CSNPs) from extracted chitosan and LMWCS. AgNPs-CSNPs were produced by incorporating AgNPs into CSNPs as antimicrobial agents. Characterization of the chitosan doped silver nanoparticles was accomplished using scanning electron microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), and X-ray Diffraction (XRD). The morphological properties of nanochitosan (ScCSNPs and ArCSNPs) and AgNPs-nanochitosan (ScCSNPs-AgNPs and ArCSNPs-AgNPs) indicated porosity and agglomeration, while functional groups -OH, -NH, and C-H were revealed. The presence of AgNPs in the polymeric matrix of nanochitosan was confirmed by a shift in some of the adsorption bands. The XRD and DSC results indicate that the nanochitosan is crystalline, and they also confirm the presence of AgNPs in the chitosan polymeric matrix. The study found that chitosan extracted from snail shells, which contribute to environmental pollution, could be a good source for the preparation of nanocomposite materials, which are useful in a variety of industrial and biomedical applications.
WITHDRAWN: Fluid flow effects on the combustion characteristics and flame stability of methane-air mixtures in millimeter-scale burners
Authors: Chen Junjie 
Published: July 2022

Abstract
This study relates to the fluid flow effects on the combustion characteristics and flame stability of methane-air mixtures in millimeter-scale burners. Numerical simulations are conducted using computational fluid dynamics to gain insights into burner performance such as temperatures, reaction rates, and flames. Fully simulations are performed that explicitly treat heat and mass transfer in the fluid as well as heat transfer in the wall. The effects of different design factors on flame stability are investigated. The effects of the velocity of fluid flow on flame stability and combustion characteristics are discussed. The factors affecting combustion characteristics are determined for cavity-stabilized burners. Particular focus is placed on determining essential factors that affect the performance of cavity-stabilized burners. The results indicate that the wall thermal conductivity and flow velocities are very important as they determine the upstream heat transfer, which is necessary for flame ignition and stability, and the material's integrity by controlling the existence of hot spots. Two modes of flame extinction occur: a spatially global type for large wall thermal conductivities and low flow velocities and blowout. There exists a narrow range of flow velocities that permit sustained combustion within a burner. For fast flows, blowout occurs, whereas for slow flows, global type extinction occurs due to slow convective heat transfer. For high inlet velocities the location of the flame shifts downstream with increasing flow rate due to the decrease in the convective timescale. For low inlet velocities, a sharp shift of the reaction zone downstream occurs with decreasing flow rate. This is due to the decrease in the heat generation rate.

Published: July 2022

Abstract
Soil salinization leads to dehydration of plants, which seriously threatens ecologically sustainable development and food security guarantee. In the complex and diverse coastal wetland environment, the impervious surface and messy soil make it difficult for traditional satellite data and algorithms to accurately and timely monitor the small surface features of salinization. This paper presents a Baseline-Based Soil Salinization Index (BSSI) for soil salinization monitoring using the medium-resolution data. In BSSI, we construct a virtual salinization baseline by connecting the near-infrared (NIR) band and the short-wave infrared-2 (SWIR2) band to enhance the spectral signature of salinized soils under the hybridized region with the impervious surface. In addition, we calculate the distance between the short-wave infrared-1 (SWIR1) band and the virtual salinization baseline as the BSSI, which can effectively improve the stability of salinity inversion for different messy soils. Through data comparison and model simulations, BSSI has shown advantages over a series of the traditional salinization spectral indices (SSIs). The results show that the saline soil extraction accuracy of BSSI exceeds 85% and the correlation coefficient of the BSSI and the degree of soil salinization exceeds 0.90. Since the related spectral bands, such as NIR, SWIR1, and SWIR2, are available on many existing satellite sensors such as Landsat TM/ETM+, OLI, and sentinel 2, the BSSI concept can be extended to establish long-term soil salinity monitoring for coastal wetland ecological environment research.

Published: July 2022

Abstract
Facial paralysis has previously been reported as a rare side effect of vaccines such as influenza (1). Among COVID-19 vaccines, there have been reports of facial paralysis associated with BNT162 and 2019-nCoV Vaccine mRNA-1273 vaccines (2). To our knowledge, there is no report of facial paresis due to the Gam-COVID-Vac vaccination. Gam-COVID-Vac vaccine (rAd26 and rAd5 vector-based) was introduced in Russia in August 2020. In September 2020 the first peer-reviewed study of its I/II phase clinical trials was published and no serious side effects were reported (3). The results of the Gam-COVID-Vac phase III clinical trial also had no report of serious side effects (4). The Gam-COVID-Vac vaccine is reported to have above 90 percent efficacy, but still, there is no official report on its safety and efficacy by international organizations (5).Iran is among the countries using the Gam-COVID-Vac vaccine. Despite using this vaccine in many countries, there has been no official report of facial paresis/palsy in association with it. Here, we present a case of mild facial paresis that occurred shortly after Gam-COVID-Vac vaccine administration in a female healthcare worker.

Abstract
Digital literacy has been receiving a lot of attention from the academic community. The aim of the study is to examine and analyse the current research status in the areas of digital literacy over the four years from 2018 to 2021. By using the keywords “digital literacy” “digital skills” and “digital competence”, this study retrieved 3057 articles from the Web of Science from 2018 to 2021. These journals are then analyzed using the Web of Science analytical search results service and the VOSviewer application based on scientometric methods. The study finds that there has been a largely upward trend in scholarly research in the field of digital literacy over these four years. Europe and the United States have contributed the most research in this field. Digital literacy is multidisciplinary, there are five main themes in this area of research: digital literacy, digital skills, higher education, education and the digital divide, with several sub-themes under each theme. The findings indicate that there does not seem to be a globally agreed definition of digital literacy and there are limitations to the existing tools for measuring digital literacy in the education field. Hence, future research could be done to determine a more inclusive measure of digital literacy that can be used in different contexts.
Nano-DMS-MaP-seq allows isoform specific RNA structure determination

Published: July 2022

Abstract
Chemical probing experiments interrogate RNA structure by reacting with unpaired residues whose positions are typically read out by mutational profiling on short-read sequencing machines. Such experiments make rapid and genome-wide measurements of RNA structure, but short sequencing reads can rarely be mapped to specific transcript isoforms. Consequently, RNA structure information is acquired as a population average in common regions between transcripts. Here, we present nanopore dimethyl-sulfate mutational profiling (Nano-DMS-MaP-seq) for obtaining isoform resolved structural information of highly similar RNA molecules. We demonstrate the utility of Nano-DMS-MaP-seq by resolving the complex structural landscape of HIV-1 transcripts in infected cells. We show that unspliced and spliced transcripts have distinct structures in the common 5’UTR explaining the specific packaging of only unspliced RNAs into viral particles. Thus, Nano-DMS-MaP-seq is a straightforward method to resolve biologically important transcript-specific RNA structures that were previously hidden in short read ensemble analyses.

Published: July 2022

The recipe composition of confectionary glaze determines its high caloricity upon the low content of physiologically significant substances. Introduction of fruit and vegetable raw materials makes it possible to increase a content of dietary fibers, vitamins, macro- and microelements in a product, as well as to reduce an amount of added sugar. This paper considers a technological possibility of introducing vegetable powders into the confectionary glaze recipe by the example of the beet powder. Physico-chemical indicators of the beet powder were studied in comparison with the classic recipe components of confectionary glaze. An effect of an amount of the beet powder (3–15%) introduced instead of part of sugar on the organoleptic, rheological and crystallization properties of glaze was studied. Organoleptic evaluation revealed that addition of the beet powder into the confectionary glaze recipe in an amount of more than 15% led to appearance of floury off-flavor. It was found that yield strength of glaze increased in the direct proportion to the content of beet powder in its composition (from 3.601 Pа to 4.446 Pa) and its value was in a range of the optimal values of 3÷7 Pа. Therefore, addition of the beet powder in an amount of up to 15% will not lead to technological difficulties. The study of the kinetics of the process of confectionary glaze structuring showed that addition of the beet powder led to a decrease in the solidification point and an increase in the time of glaze crystallization. The main crystallization parameters of the developed glaze were established: solidification point Tmax=28.0÷28.3°C, crystallization time τmax=8.2÷8.6 min. Based on the performed research, the following recipes were developed: vegetable-containing confectionary glaze with the beet powder content of 3 to 10%; vegetable confectionery glaze with the beet powder content of 13%.

The global concept of conscious consumption and healthy life-style affects the development of the food industry. As a consequence, over the last several decades, a production of sugar substitutes has been increased, a search for and creation of new sweetening substances have been carried out. The paper presents a review of the domestic and foreign studies devoted to the use of sugar substitutes in various branches of the food industry. The information about new types of sugar substitutes from natural starch-containing raw materials and their properties is given. A possibility of replacing crystalline sugar with sugar substitutes in food production is described, their effect on the physico-chemical, sensory and organoleptic properties of foods and beverages is demonstrated. The development of the technologies facilitates an extension of the range of well-known and widely used high-calorie sugar substitutes from starch-containing raw materials, characterized by different carbohydrate composition and properties. It has been noted that out of quite a large number of sugar substitutes applied in the food industry abroad, glucose-fructose syrups (GFS) are among most promising. They are full-value sucrose substitutes and have several advantages. A proportion of GFS in the total volume of sugar syrup consumption is increasing worldwide every year. The main raw material for production of GFS in the USA is corn starch; in the CIS countries, starch obtained from wheat and potato is also used. Studies aimed to investigation and development of bioprocesses that ensure production of competitive enzymatic GFS and other sweetening syrups from alternative sources are gaining in importance. The information is presented about the development of the innovative technologies for production of sugar syrups from Jerusalem artichoke and chicory, agave, yacon, sorghum and rice. The results of the study of properties of these syrups and their effect on the physical and sensory, rheological and microstructural properties of products, in which technologies these syrups were used, are described. Due to the different carbohydrate composition, as well as physico-chemical properties (a degree of hygroscopicity, anti-crystallization properties, a level of sweetness, glycemic index and so on), sugar substitutes acquire increasing popularity among producers and consumers, and can be used in food and beverage manufacturing as a more technological replacement of crystalline sugar.

Oxidative stress, to which many modern people are subjected, promotes the development of neurodegenerative, cardiovascular, inflammatory, oncological and other socially important diseases. The antioxidant system consisting in the endogenous and exogenous antioxidants exists in the body to regulate the action of free radicals and reactive oxygen species. The main source of exogenous antioxidants is food and this conditions an increase in the demand for functional foods. The market of functional drinks based on teas, cereal products, fruit and vegetable juices is developing especially actively. Drinks based on oat flakes with addition of plant components are distinguished by the high nutrition value being a rich source of dietary fibers, vitamins, minerals and antioxidants. During the experiment, a functional drink based on oat flakes and enriched with bananas, blueberry berries and a powder of elder (Sambucus nigra L.) berries recognized for the high content of anthocyanins was developed. The antioxidant potential of the experimental product was assessed by measuring the total antioxidant capacity (TAC) by the FRAP method and determining the antiradical activity (ARA) by the DPPH method. The TAC values for the aqueous and methanol extracts were 807.3±18.0 µmol quercitin equivalents /L and 948.7±47.9 µmol quercitin equivalents/L, respectively, which significantly exceeded the similar values in the control sample (by 2.44 and 1.69 times, respectively). The ARA of the methanol extract of the experimental drink was 86.49±2.01%, which was 1.9 times higher than the ARA of the control sample. It was established that about 10% of fat-soluble antioxidants are lost upon preparation of oat-based functional drinks with addition of elder berries.

Women in postmenopausal period of their life face various physical and physiological changes causing lack of estrogen and progesterone hormones, changes in the reproductive and genitals organs, vasomotor system in the body along with mood related symptoms such as anxiety, etc. Lifestyle, body fat distribution and anthropometric changes adds on to the bone strength in postmenopausal women. It may be a risk factor for osteoporotic fracture, cardiovascular, metabolic diseases, etc. Core strength and stability is greatly influenced by body composition and adiposity. The aim of the study was to correlate the core strength assessed with the Body Mass Index (BMI) among postmenopausal women. The objective of the study is to find the correlation between the core strength assessed with the Body Mass Index using 60° flexion test, Beiring Sorenson test and Unilateral Hip Bridge Endurance test among postmenopausal women with age ranging from 46-70 years. 96 healthy postmenopausal women in Karad city with a natural history of menopause were selected for the study. Based upon BMI values, the subjects were grouped as Underweight (<18.5 kg/m2), Normal weight (18.5-24.9 kg/m2), Overweight (25-29.9 kg/m2 and more). The outcome values for strength were correlated with the BMI of postmenopausal women. In the study, the Pearson correlation(r) was -0.361 and the P value was 0.0003 showing extremely significant correlation between the BMI and 60° Flexion test. For the Beiring Sorenson Test, the Pearson correlation value was -0.305 and the P value was 0.0025 showing very significant correlation between the BMI and Beiring Sorenson Test. Correlation of BMI and Unilateral Hip Bridge Endurance Test shows a Pearson Correlation value of -0.322 and the P value 0.0013 claiming very significant correlation between the BMI and Unilateral Hip Bridge Endurance Test. The study concludes that there is a significantly negative correlation between the core strength and stability with the Body Mass Index among postmenopausal women.
