Published: February 2023

Background: Depression is a mood disorder characterised by loss of interest and enjoyment (anhedonia), and reduced energy leading to increased fatigability and diminished activity. Depression is a major contributor to the overall global burden of disease. It has a profound effect on adolescents because those who experience depression at an early age often struggle with depression throughout their lives, and in many cases, early onset of depression predicts more severe depression during adulthood. Objectives: This study aimed to determine the prevalence of depression and associated factors among secondary school adolescents in Gombe, Nigeria. Methodology: Three hundred and ninety-five adolescents aged 13- 18 years were selected using a multistage sampling method. The Beck Depression Inventory-II (BDI-II) was used to assess depression and a structured questionnaire was used to obtain the sociodemographic characteristics of the subjects. Results: The mean age of subjects was 16.2±1.4 years. The prevalence of depression was 37.7% (142/377). Subjects from low socio-economic class (χ2= 30.601, p< 0.001). Subjects with non-parental caregivers were 4.8 times more likely to be depressed than those that had parental caregivers (OR 4.760, CI 1.882-12.04). Depression was significantly higher among subjects from public schools (χ2= 22.698, p< 0.001). Also, the majority of the subjects who failed the exams preceding the study had depression as compared to those that passed the exams (χ2=5.389, p= 0.030). Conclusion: The burden of depression is high among adolescent secondary school students in Gombe. Psychosocial stressors such as low social class, non-parental care, parental divorce and poor academic performance are significant determinants of depression among adolescents. Early detection of depression is recommended as it has a strong relationship with suicidal ideation among adolescents.

Published: February 2023

يحتلُّ موضوع الصحابة في علم الحديث مكانةً مهمّةً، فالصحابة هم حملة حديث النبي ﷺ ونقلتُه للناس، ومحاولةُ النيل من مكانتهم مقدمةٌ للنيل من الحديث النبوي الشريف.

وقد تجاذبت أقلامُ الكُتَّاب هذا الموضوع، بين من يعطي الصحابة مكانةً متميِّزةً، وبين من يجعلهم كسائر الرواة، ولكل فريقٍ أدلةٌ.

والبحث في موضوع الصحابة يستدعي البحث في جملة من القضايا منها: بيان حد الصحابة، وهل ينال شرف الصحبة كل من لقي النبي ﷺ أم لا بد من شروط إضافية أخرى؟ مع عرضٍ للأقوال الأخرى وأدلتهم ومناقشتها.

تناول البحث موضوع عدالة الصحابة، وعرض أدلة الفريقين ومناقشة أدلتهم. ويعرض لشبهة وجود المنافقين بين ظهراني الصحابة، ما يجعل القول بتعديل الصحابة على خطر تعديل المنافقين، وبالتالي قبول روايتهم.

كما تناول البحث موضوع ضبط الصحابة، وهل يستلزم القول بتعديل كل الصحابة إثبات الضبط لهم؟

وقد اعتمد البحث على المنهج الاستقرائي التحليلي، فتتبع عمل العقلانيين المعاصرين في هذا المضمار، ثم قام بتحليل طريقتهم في التعامل مع موضوع الصحابة، وصولاً إلى أهم ما انتقدوه على المحدثين في تعاملهم مع هذا الموضوع.

Authors: Venkataraman Prasanna , Neil Amanda L , Mitchell Geoffrey K , Stanton Tony , Nicholls Stephen , Tonkin Andrew M , Watts Gerald F , Marwick Thomas H
Published: February 2023

Objectives

To compare the cost‐effectiveness of coronary artery calcium (CAC) score‐guided statin therapy criteria and American College of Cardiology/American Heart Association (ACC/AHA) guidelines (10‐year pooled cohort equation [PCE] risk ≥ 7.5%) with selection according to Australian guidelines (5‐year absolute cardiovascular disease risk [ACVDR] ≥ 10%), for people with family histories of premature coronary artery disease.

Study design, setting

Markov microsimulation state transition model based on data from the Coronary Artery calcium score: Use to Guide management of Hereditary Coronary Artery Disease (CAUGHT‐CAD) trial and transition probabilities derived from published statin prescribing and adherence outcomes and clinical data.

Participants

1083 people with family histories of premature coronary artery disease but no symptomatic cardiovascular disease.

Main outcome measures

Relative cost‐effectiveness over fifteen years, from the perspective of the Australian health care system, compared with usual care (Australian guidelines), assessed as incremental cost‐effectiveness ratios (ICERs), with a notional willingness‐to‐pay threshold of $50 000 per quality‐adjusted life‐year (QALY) gained.

Results

Applying the Australian guidelines, 77 people were eligible for statin therapy (7.1%); with ACVDR 5‐year risk ≥ 2% and CAC score > 0, 496 people (46%); with ACVDR 5‐year risk ≥ 2% and CAC score ≥ 100, 155 people (14%); and with the ACC/AHA guidelines, 256 people (24%). The ICERs for CAC‐guided selection were $33 108 (CAC ≥ 100) and $53 028 per QALY gained (CAC > 0); the ACC/AHA guidelines approach (ICER, $909 241 per QALY gained) was not cost‐effective. CAC score‐guided selection (CAC ≥ 100) was cost‐effective for people with 5‐year ACVDR of at least 5%.

Conclusion

Expanding the number of people at low to intermediate CVD risk eligible for statin therapy should selectively target people with subclinical atherosclerosis identified by CAC screening. This approach can be more cost‐effective than simply lowering treatment eligibility thresholds.

Objective: Animal feed companies and researchers are currently embarking on quests for feed additives that could combat the pathogens while promoting growth as well as maintaining quality products. The current study aimed to evaluate the effects of onion extracts on growth performance, carcass quality, and bone morphometrics of broiler chickens.Methods: A total number of 200 one-day-old unsexed Ross 308 broiler chicks were assigned to 5 treatment groups, replicated 4 times. Each replicate (pens) held 10 chickens in a completely randomized design. The experimental diets were then randomly allotted to the pens which act as experimental units. The isoenergetic and isonitrogenous diets were formulated by including onion extracts at 0, 5, 10, 15, or 25 g/kg in a complete broiler diet. Feed intake, and body weight, were recorded then used to calculate feed conversion ratio. At the end of the experiment (42 days), four chickens from each pen were randomly selected for slaughter for carcass, bone morphology and sensory evaluation.Results: Results showed that onion extract supplementation did not affect (p>0.05) growth performances and meat sensory evaluation. However, there was a significantly increased (p<0.05) meat shear force in groups receiving onion extracts dietary treatments. Furthermore, onion extracts improved (p<0.05) bone morphology of broiler chickens in terms of weight, diameter, calcium, and phosphorous contents.Conclusion: In conclusion, onion extracts can be safely included in a commercial broiler diet as a growth promoter without causing adverse effects on growth performance traits and carcass quality in chickens. Onion extract supplementation improved tibia bone growth and strength in broiler chickens.

Objective: The clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated protein 9 (Cas9) system, which is the most efficient and reliable tool for precisely targeted modification of the genome of living cells, has generated considerable excitement for industrial applications as well as scientific research. In this study, we developed a gene-editing and detection system for chick embryo sexing during the embryonic stage.Methods: By combining the CRISPR/Cas9 technical platform and germ cell-mediated germline transmission, we not only generated Z chromosome-targeted knockin chickens but also developed a detection system for fluorescence-positive male chicks in the embryonic stage.Results: We targeted a green fluorescent protein (GFP) transgene into a specific locus on the Z chromosome of chicken primordial germ cells (PGCs), resulting in the production of ZGFP-knockin chickens. By mating ZGFP-knockin females (ZGFP/W) with wild males (Z/Z) and using a GFP detection system, we could identify chick sex, as the GFP transgene was expressed on the Z chromosome only in male offspring (ZGFP/Z) even before hatching.Conclusion: Our results demonstrate that the CRISPR/Cas9 technical platform with chicken PGCs facilitates the production of specific genome-edited chickens for basic research as well as practical applications.

Authors: de Oliveira Alessandra M. R. C. B. , Yu Peiqiang
Published: February 2023

Objective: The objective of this study was to characterize physiochemical and nutrient profiles of feedstock and co-products from canola bio-oil processing that were impacted by source origin. The feedstocks and co-products (mash, pellet) were randomly collected from five different bio-oil processing plants with five different batches of samples in each bio-processing plant in Canada (CA) and China (CH).Methods: The detailed chemical composition, energy profile, total digestible nutrient (TDN), protein and carbohydrate subfractions, and their degradation and digestion (CNCPS6.5) were determined.Results: The results showed that TDN1x was similar in meals between CA and CH. CH meals and feedstock had higher, truly digestible crude protein (tdCP) and neutral detergent fiber (tdNDF) than CA while CA had higher truly digestible non-fiber carbohydrate (tdNFC). The metabolizable energy (ME3x), net energy (NELp3x, NEm3x, and NEg3x) were similar in meals between CA and CH. No differences were observed in energy profile of seeds between CA and CH. The protein and carbohydrate subfractions of seeds within CH were similar. The results also showed that pelleting of meals affected protein sub-fractionation of CA meals, except rapidly degradable fractions (PB1), rumen degradable (RDPB1) and undegrdable PB1 (RUPB1), and intestinal digestible PB1 (DIGPB1). Canola meals were different in the soluble (PA2) and slowly degradable fractions (PB2) between CA and CH. The carbohydrate fractions of intermediately degradable fraction (CB2), slowly degradable fraction (CB3), and undegradable fraction (CC) were different among CH meals. CH presented higher soluble carbohydrate (CA4) and lower CB2, and CC than CA meals.Conclusion: The results indicated that although the seeds were similar within and between CA and CH, either oil-extraction process or meal pelleting seemed to have generated significantly different aspects in physiochemical and nutrient profiles in the meals. Nutritionists and producers need to regularly check nutritional value of meal mash and pellets for precision feeding.

Authors: Lee Soohyung , Yoo Inkyu , Cheon Yugyeong , Ka Hakhyun
Published: February 2023

Objective: Two serine protease inhibitors, peptidase inhibitor 3 (PI3) and secretory leukocyte protease inhibitor (SLPI), play important roles in protease inhibition and antimicrobial activity, but their expression, regulation, and function at the maternal–fetal interface in pigs are not fully understood. Therefore, we determined the expression and regulation of PI3 and SLPI in the endometrium throughout the estrous cycle and at the maternal–fetal interface in pigs.Methods: Endometrial tissues during the estrous cycle and pregnancy, conceptus tissues during early pregnancy, and chorioallantoic tissues during mid to late pregnancy were obtained, and the expression of PI3 and SLPI was analyzed. The effects of the steroid hormones estradiol-17β (E2) and progesterone (P4) on the expression of PI3 and SLPI were determined in endometrial explant cultures.Results: PI3 and SLPI were expressed in the endometrium during the estrous cycle and pregnancy, with higher levels during mid to late pregnancy than during the estrous cycle and early pregnancy. Early-stage conceptuses and chorioallantoic tissues during mid to late pregnancy also expressed PI3 and SLPI. PI3 protein and SLPI mRNA were primarily localized to endometrial epithelia. In endometrial explant cultures, the expression of PI3 was induced by increasing doses of P4, and the expression of SLPI was induced by increasing doses of E2 and P4.Conclusion: These results suggest that the PI3 and SLPI expressed in the endometrium and conceptus tissues play an important role in antimicrobial activity for fetal protection against potential pathogens and in blocking protease actions to allow epitheliochorial placenta formation.

Published: February 2023

Objective: This study was conducted to evaluate Raman spectroscopy technique as a noninvasive tool to predict meat quality traits on Braford longissimus thoracis et lumborum muscle.Methods: Thirty samples of muscle from Braford steers were analyzed by classical meat quality techniques and by Raman spectroscopy with 785 nm laser excitation. Water holding capacity (WHC), intramuscular fat content (IMF), cooking loss (CL), and texture profile analysis recording hardness, cohesiveness, and chewiness were determined, along with fiber diameter and sarcomere length by scanning electron microscopy. Warner-Bratzler shear force (WBSF) analysis was used to differentiate tender and tough meat groups.Results: Higher values of cohesiveness and CL, together with lower values of WHC, IMF, and shorter sarcomere were obtained for tender meat samples than for the tougher ones. Raman spectra analysis allows tender and tough sample differentiation. The correlation between the quality attributes predicted by Raman and the physical measurements resulted in values of R2 = 0.69 for hardness and 0,58 for WBSF. Pearson's correlation coefficient of hardness (r = 0.84) and WBSF (r = 0.79) parameters with the phenylalanine Raman signal at 1,003 cm-1, suggests that the content of this amino acid could explain the differences between samples.Conclusion: Raman spectroscopy with 785 nm laser excitation is a suitable and accurate technique to identify beef with different quality attributes.
Doxorubicin-Loaded Multivesicular Liposomes (DepoFoam) as a Sustained Release Carrier Intended for Locoregional Delivery in Cancer Treatment: Development, Characterization, and Cytotoxicity Evaluation
Authors: Mahjoub Mohammad Ali , Dadashzadeh Simin , Haeri Azadeh , Shahhosseini Soraya , Abbasian Zahra , Nowroozi Fatemeh
Published: February 2023

Background: Despite the advantages of direct intratumoral (IT) injection, the relatively rapid withdrawal of most anti-cancer drugs from the tumor due to their small molecular size limits the effectiveness of this method of administration. To address these limitations, recently, increasing attention has been directed to using slow-release biodegradable delivery systems for IT injection. Objectives: This study aimed to develop and characterize a doxorubicin-loaded DepoFoam system as an efficient controlled-release carrier to be employed for locoregional drug delivery in cancer treatment. Methods: Major formulation parameters, including the molar ratio of cholesterol to the main lipid [Chol/egg phosphatidylcholine (EPC)], triolein (TO) content, and lipid-to-drug molar ratio (L/D), were optimized using a two-level factorial design approach. The prepared batches were evaluated for encapsulation efficiency (EE) and percentage of drug release (DR) after 6 and 72 hours as dependent variables. The optimum formulation (named DepoDOX) was further evaluated in terms of particle size, morphology, zeta potential, stability, Fourier-transform infrared spectroscopy, in vitro cytotoxicity, and hemolysis. Results: The analysis of factorial design indicated that TO content and L/D ratio had a negative effect on EE; between these two, TO content had the greatest effect. The TO content was also the most significant component, with a negative effect on the release rate. The ratio of Chol/EPC showed a dual effect on the DR rate. Using a higher percentage of Chol slowed down the initial release phase of the drug; nevertheless, it accelerated the DR rate in the later slow phase. DepoDOX were spherical and honeycomb-like structures (≈ 9.81 μm) with a desired sustained release profile, as DR lasted 11 days. Its biocompatibility was confirmed by the results of cytotoxicity and hemolysis assays. Conclusions: The in vitro characterization of optimized DepoFoam formulation demonstrated its suitability for direct locoregional delivery. DepoDOX, as a biocompatible lipid-based formulation, showed appropriate particle size, high capability for encapsulating doxorubicin, superior physical stability, and a markedly prolonged DR rate. Therefore, this formulation could be considered a promising candidate for locoregional drug delivery in cancer treatment.

Authors: Azizi Maryam , Ahmadi Fazlollah , Kazemnejad Anoshirvan
Published: February 2023

Background: Surgery is one of the most frequent healthcare events worldwide. Individuals have different expectations of surgery. As most adult patients have a family member beside them and the family presence is important, this study was aimed to explain the expectations of the families of patients undergoing surgery. Methods: This qualitative study was carried out using the conventional content analysis method. A purposive sample of the family members of patients undergoing surgery was recruited with maximum variation from hospitals in Tehran, Iran, in 2019. The sampling method was purposive sampling. The data were collected through semi-structured interviews. Data collection was continued until the categories were saturated. In total, 29 interviews were conducted with 25 family members, 3 nurses, and 1 surgeon. Results: Overall, 29 interviews were conducted. A total of 811 primary codes without overlap, 446 primary codes with overlap, 36 subcategories, and 11 generic categories were extracted. Finally, four main categories were obtained, named endless confusion, giving the family a share in care, exaggerated focus on obvious behaviors, and accepting the existence of the family. Conclusions: Families come apart at the seams. Their expectations and needs might not be met and are usually considered unimportant. They need to be seen, heard, considered, understood, and, most importantly, accepted by healthcare providers, especially nurses.

Published: February 2023

Background: Correct endotracheal tube suction is one of the effective methods to prevent ventilator-associated infection. Many studies have reported that normal saline and N-acetylcysteine (NAC) in the trachea lead the translocation of bacteria to lower levels and increase the risk of pneumonia. Objectives: The present study sought to examine the effect of tracheal suction with NAC on the incidence of ventilator-associated pneumonia (VAP). Methods: This single-blind randomized clinical trial study was conducted on 60 patients admitted to the intensive care unit (ICU) of the Khatam Al-Anbia Hospital in Zahedan, Iran, in 2020. The patients were selected using the convenience sampling method and assigned into two intervention and control groups by permutation block randomization. Before the intervention, the patients were evaluated using the Modified Clinical Pulmonary Infection Score (MCPIS), and the patients with scores < 5 on this scale were included in the study. Suctioning tracheal secretions in the intervention group was performed by pouring 2 cc of NAC into the tracheal tube during suction. The same suction procedure was performed for the patients in the control group by pouring 2 cc of normal saline into the tracheal tube in a standard way. The intervention was conducted for five days. After the intervention, the MCPIS scale was administered once more for the two groups. The collected data were analyzed using the independent samples t-test and chi-square test with SPSS software (version 25). Results: The independent samples t-test showed no significant difference between the intervention and control groups regarding the incidence of pneumonia (P = 0.31). Conclusions: Despite the effect of NAC on the incidence rate of pneumonia in patients under mechanical ventilation, there was no significant difference between NAC and normal saline in reducing the incidence of pneumonia. However, since NAC leads to no specific complication in patients, it can be safely used in the suction of tracheal lobule secretions in patients under ventilators. In this regard, further studies should examine the use of NAC for suctioning during tracheal tube obstruction by secretions.
ALMA KARLIN, THE YOUNGEST GRANDDAUGHTER OF THE HONORABLE I CHAO (I TSCHAOS JÜNGSTES ENKELKIND), 1948, 2016
Authors: Blažić Milena Mileva
Published: February 2023

This article was created on the basis of the study of the life and work of the Slovene writer Alma Karlin (1889–1950), who spent a large part of her life abroad, during her trips around the world. She mainly published in German, during the period between World War I and World War II. Some of her works are open in the manner of crosswriting, including the analyzed fairy tale The Youngest Granddaughter of the Honorable I Chao which was originally published in 1948 in German and in 2016 in Slovene. With this fairy tale, the writer intertextually related to the model of the folk fairy tale, the European fairy tale, and the ATU514 and ATU884 international fairytale type. The detailed analysis and application of the theory of Slavo jŽižek, entitled From Antigone to Joan of Arc, confirms the hypothesis that Alma’s fairytale belongs to the literary tradition from Antigone to the present, that the fairy tale contains the features of subjectivization of a literary heroine, which is a universal element (fairytale type or motif), and Alma also added to the text the typical characteristics of Chinese culture.

Keywords: Alma Karlin, fairy tales, ATU 514, ATU 884, M. Lüthi, H. J. Uther, Slavoj Žižek.

Influência motivacional aos colaboradores da Administração Pública aplicada ao seu rendimento no processo produtivo.
Authors: Estevão Camila Lima
Published: February 2023

Buscando responder quanto a possibilidade de se motivar colaboradores estabilizados por concursos públicos, foram buscadas fontes bibliográficas voltadas às Teorias de Motivação e Administração Pública, e é notável após realização destes estudos que há sim tal possibilidade. Porém para que isto aconteça é necessário que os gestores tenham cautela ao aplicar as teorias mencionadas, visto que o fato de ser realizada em ambiente público faz com que haja particularidades não existentes no ambiente privado. O administrador público pode se ancorar tanto em teorias metodológicas quanto nas conceituais, buscando aplicar os aspectos essenciais para melhoria no clima e cultura organizacional incentivando os servidores a buscarem a excelência em suas responsabilidades laborais. Por meio dos estudos quanto aos aspectos motivacionais fica claro que cada servidor almeja alcançar excelência, através de seu trabalho, satisfazendo realizações pessoais de autodesenvolvimento. Sendo assim, a percepção de que não há como motivar o servidor público cai por terra quando notamos que cabe ao gestor aplicar estímulos que otimizarão o funcionalismo público.

A Gestão por Competências Alternativas é considerada um modelo gerencial às organizações utilizadas, pois contempla metodologias diferenciadas, variando de competências estratégicas organizacionais e individuais). Este artigo teve como objetivo analisar o cenário atual das publicações sobre GC na base Scopus. Por meio da análise bibliométrica em uma amostra de 263 artigos, foram extraídos os indicadores para discussão, além da leitura de 7 estudos publicados recentemente para identificação da agenda de pesquisa. Como resultados foi identificada uma tendência ascendente nas publicações sobre GC, mas com maior concentração nos anos de 2011, 2015, 2016 e 2021. Verificou-se também que o Brasil possui o maior volume de pesquisas, embora o continente europeu tenha se destacado em produtividade por universidades afiliadas. De modo geral, as pesquisas vêm sendo realizadas por meio de cooperação interna dos países e com elevado número de pesquisadores que publicaram apenas um artigo. A análise temática demonstrou abordagens da GC na área médica, na formação profissional de estudantes e na estratégia organizacional. A agenda de pesquisa demonstrou lacunas voltadas à ampliação das amostras, períodos e variáveis utilizadas, além dos impactos que essa abordagem pode causar nos negócios das organizações. Conclui-se que GC ainda é um tema em constante expansão, relacionando-se principalmente a períodos de mudanças no contexto socioeconômico.

Authors: Rasgele Pinar , Altin Nedim
Published: February 2023

We investigated the antimutagenic activities and chemical compositionsof essential oil (EO) from Melissa officinalis, Lavandula angustifolia and Origanum onites plants belonging to the Lamiaceae family. The chemical compositions of the plants were determined by GC/MS analysis and Ames assay was used in antimutagenic activity analysis. Citral, linalool, thymol and terpinenes were the major components in the EOs of M. officinalis, L. angustifolia and O. onites. In Ames assay, it was determined that the EO of M. officinalis had strong antimutagenic effects at all concentrations except for the highest concentrations on Salmonella typhimurium TA98 and 100 strains. L. angustifolia EO showed moderate antimutagenic activity against the Sodium azide (NaN3) mutagen, and reduced mutant colonies with 25.40% inhibition effect in the S. typhimurium TA100 strain at only 0.1 μl/plate concentration. Furthermore, L. angustifolia EO indicated strong antimutagenic activity against both 4-Nitro-o-phenylendiamine (NPD) and NaN3 mutagens in the S. typhimurium TA98 and 100 strains at 0.5 and 1 μl/plate concentrations. It was determined that the EO of O. onites had a moderate antimutagenic effect at the lowest concentration and a strong antimutagenic effect at all other concentrations on S. typhimurium TA98 strain. The 0.01, 0.05 and 0.1 μl/plate concentrations of EO of O. onites showed strong antimutagenic effect against S. typhimurium TA100 strain. The present study demonstrated that EOs of M. officinalis, L. angustifolia and O. onites possesses antimutagenic activity on the S. typhimurium TA98 and 100 strains.
Contribution to the Knowledge of Pontechium maculatum(Boraginaceae), a Species of High Conservation Concern in the Bulgarian Flora
Authors: Vladimirov Vladimir , Bancheva Svetlana , Ivanova Daniella
Published: February 2023

Pontechium maculatum (Boraginaceae) is a species of high conservation concern in the Bulgarian flora. It is assigned a national IUCN category ‘Vulnerable’, legally protected according to the national Biological Diversity Act, and listed in Annex II of the Habitats Directive (Council Directive 92/43/EEC). Recent studies in one of the largest populations in the country revealed some new data about the species which are reported here. The population studied is situated in Mt Lozenska, Mt Sredna Gora (Western) floristic region. Relevant taxonomic literature states that P. maculatum is a biennial plant, however, our observations revealed the plants in Mt Lozenska are perennial (possibly short-lived). A great variation in the corolla-colour was observed, most plants having bluish to violet corolla and only a few – reddish to dark red. This can be explained by either natural variation in the population, not reported in the taxonomic literature so far, or by hybridisation with Echium vulgare which cooccurs in the same locality. Large fluctuation in the number of flowering plants in two consecutive years was recorded, with some 180 blooming specimens in 2019 and only about 25 in 2020. Studies in the genome size of this population revealed the plants have significantly higher DNA-content (1C-value) than plants from the typical populations of the species in Northeast Bulgaria floristic region, e.g. Kabiyushka Mogila locality. Further biosystematics studies(chromosome number, genome size, genetic studies, etc.) are currently in progress to explain the observed phenomena within the Bulgarian populations of P. maculatum.
New Sensor Technology for Determining Rock Pre-destructive States
Authors: Lozanova Siya , Ralchev Martin , Roumenin Chavdar
Published: February 2023

Based on the experimentally discovered regularity – emission of micro-sized particles during monoaxial deformation of non-homogeneous structures, such as rocks and concretes, a sensor technology to identify their pre-destruction processes is proposed. At nearing the stressed state until the disintegration of the massifs, exponential increase of particles generation appears. The innovation is applicable to risky rock formations where vertical measurement boreholes are made, by which kernels are obtained. Using the specimens formed by the kernels, through monoaxial load by press in laboratory conditions and corresponding particle emissions, the reference pressure values for different stages of the pre-destructive state development are determined. The reference data from the pressure are compared with the results for the deformation loads in the rock structure, corresponding to the generated particles in a borehole model. The values of the stress determine the occurrence of critical states in the structure. This information is an integrated indicator for the timely identification of pre-destructive processes in rocks. The described system increases the accuracy of determining the appearance of failure conditions. One of the strategic applications of the new technology is in seismically active regions.

Published: February 2023

The long-term use of renewable energy investments which have gained importance in recent years, can be realized by tracking errors and malfunctions. It is very important to determine the cracks, microcracks and flaws that occur especially during the production and use of solar energy panels. Errors in the panels can seriously affect the energy production performance of the installed system. According to the panel arrangement in the power plant, flaws in any panel not only affect the energy production of a single panel, but also reduce the production of the entire series to which it is connected. Cracks and faults in solar panels cannot be seen with the naked eye, but can be determined by electroluminescence images. However, detecting these errors requires special expertise and a long examination time. In this study, fractures, microcracks and connection errors are detected automatically from electroluminescence images taken from photovoltaic panels. Before analyzing the images taken with the electroluminescence device, some preprocessing is required. Since the images taken from the installed power plants are not standard in terms of layout, background removal, size and perspective correction are required. In the study, the panels are not examined as a whole, but cell-based examination is carried out. For this reason, the panels are divided into cells. By applying the Matched filter to the dividing cell images, the fractures and cracks are highlighted and the features are extracted. The obtained features are evaluated statistically and the cell status is determined. An accuracy of 98.6% is achieved in determining cell damage status. The losses in the power generation performance of the panel are calculated according to the status of all cells on the panel. The calculated values are compared with the measured I-V values. As a result, efficiency loss was calculated with an accuracy rate of 96.2%.

Currently, single-image super-resolution reconstruction based on deep learning has achieved good results. To address the problems that most networks will have long training time, weak image learning ability and not fully utilizing the high frequency information of images, an image super-resolution reconstruction method based on residual convolution and double attention mechanism is proposed. The model performs deep feature extraction of the image by cascading deep convolutional networks, introduces local residual blocks to solve the model degradation brought by too many network parameters, and embeds the dual attention mechanism module in the residual blocks for adaptive calibration to adjust the feature map weights of each channel and the spatial correlation between features, so as to obtain deep texture detail information and reconstruct the feature image by sub-pixel convolutional layers to up sampling to reconstruct the high-resolution image. In the test sets of Set5 and Set14, peak signal-to-noise ratio (PSNR) and structural similarity (SSIM) are used as evaluation indexes, while comparing SRCNN, FSRCNN and VDSR methods all reconstructed images with better results. The experimental results show that the method can effectively improve the utilization of high-frequency feature information and can increase the reconstruction capability of the images to a certain extent.
A daily diary study on stressors, hurt feelings, aggression, and somatic symptoms: The role of rejection sensitivity and negative emotion differentiation
Authors: Yang Yang
Published: February 2023

The current study adopted a daily diary design to examine associations of daily stressors and hurt feelings to three unfavorable daily outcomes, including verbal aggression, physical aggression, and somatic symptoms and the moderation of rejection sensitivity and negative emotion regulation on the relations between these daily variables. A total of 248 college students participated in the daily diary study in which they responded to the assessment on a daily basis for 7 consecutive days. The results indicated that daily stressors predicted daily verbal aggression; daily stressors, daily hurt feelings, and rejection sensitivity predicted somatic symptoms. Negative emotion regulation moderated the association between stressors and verbal aggression such that more stressors and high negative emotion regulation predicted more frequent daily verbal aggression. Rejection sensitivity moderated the association of hurt feelings to verbal and physical aggression. Perception of hurt feelings and high rejection sensitivity predicted more verbal aggression but less physical aggression. Rejection sensitivity also moderated the association of stressors to somatic symptoms such that more stressors and high rejection sensitivity predicted more somatic symptoms. The findings collectively highlight the importance of supporting individuals with high rejection sensitivity to encode social cues in a healthy way. It is imperative to provide emotion regulation skills to cope with negative emotions derived from social interactions.

In this exploratory study, we analyzed the contribution of fathering to relational aggression (RA) in middle childhood and the moderating role of children's temperament and gender. Participants (N = 234; 46% girls) were attending public elementary school (mean age = 8.15; SD = 1.23) in middle‐class neighborhoods in two Spanish cities. Fathers provided information about their parenting practices using the Parenting Styles and Dimensions Questionnaire, parents gave data on their child's temperament using the Temperament in Middle Childhood Questionnaire and children provided information about their peers’ aggressive behavior using the Mini Direct Indirect Aggression Inventory. Fathering dimensions considered were Authoritative Cold, Authoritative Warm, Physical Punishment, and Insecurity; temperament dimensions considered were negative affect (NA), effortful control (EC), activity (AC), and shyness (SH). Gender, fathering, and temperament dimensions additively accounted for a significant proportion of the variance observed in RA. Several significant interactions suggested that the effect of fathering on RA was moderated by temperament and, in some cases, by children's gender. NA increased the potential risk of Authoritative Cold fathering (CF) and, in boys only, of Insecure fathering, while EC potentiated the protective effect of Authoritative‐Warm fathering and, in boys only, buffered the risk effect of CF. SH buffered the risk effect of CF and decreased the protective effect of Authoritative Warm fathering on RA. Lastly, AC also buffered the risk effect of CF on RA. Results are discussed in light of the protective or the vulnerability role of temperament and in relation to models that explain sensitivity differences to environmental contexts.

Authors: Guo Yongfen , Xia Ling‐Xiang
Published: February 2023

Cyberbullying is a new form of aggression and can have serious consequences. Although the influencing factors of cyberbullying have been explored in the literature, less is known of the longitudinal effects of relative deprivation on cyberbullying and the mediating mechanisms underlying the effect. In this study, we explored these problems. A total of 1143 undergraduates (62.9% women, mean age = 19.46, standard deviation [SD] = 0.95) participated in three rounds of a longitudinal survey with an interval of 6 months and completed a series of self‐reported questionnaires assessing relative deprivation, revenge, and cyberbullying. The results of random intercept cross‐lagged panel model showed that at between‐person level, the random intercepts of relative deprivation, revenge, and cyberbullying were positively associated with each other. At within‐person level, relative deprivation and revenge could predict each other over time, and revenge longitudinally predicted cyberbullying. Moreover, revenge mediated the longitudinal effect of relative deprivation on cyberbullying. The results support and develop the view of the general aggression model and deepen our understanding of the development mechanism of cyberbullying.
Directing Group‐Free Regioselective meta‐C−H Functionalization of Pyridines

The pyridine core is among the most common motifs found in pharmaceuticals and agrochemicals. Consequently, the C−H functionalization of pyridine is a prized reaction, as it can help access a broad spectrum of valuable chemicals. However, the intrinsic electronic properties of pyridines hinder their meta‐C−H functionalization, requiring drastic conditions affecting functional group compatibility. A synthetic manoeuvre to overcome this challenge involves the temporary conversion of pyridines into electron‐rich intermediates and subsequent regioselective electrophilic functionalization. This was recently accomplished by a ring‐opening ring‐closing sequence via Zincke imine intermediates by McNally and co‐workers, and a dearomatization‐rearomatization sequence via oxazino‐pyridine intermediates by the Studer group. The mildness and simplicity of these protocols enable them to work with complex molecular setups for synthesizing natural products and bioactive molecules.

In overcoming the Li+ desolvation barrier for low‐temperature battery operation, a weakly‐solvated electrolyte based on carboxylate solvent has shown promises. In case of an organic‐anion‐enriched primary solvation sheath (PSS), we found that the electrolyte tends to form a highly swollen, unstable solid electrolyte interphase (SEI) that shows a high permeability to the electrolyte components, accounting for quickly declined electrochemical performance of graphite‐based anode. Here we proposed a facile strategy to tune the swelling property of SEI by introducing an inorganic anion switch into the PSS, via LiDFP co‐solute method. By forming a low‐swelling, Li3PO4‐rich SEI, the electrolyte‐consuming parasitic reactions and solvent co‐intercalation at graphite‐electrolyte interface are suppressed, which contributes to efficient Li+ transport, reversible Li+ (de)intercalation and stable structural evolution of graphite anode in high‐energy Li‐ion batteries at a low temperature of −20 °C.

The assembly and function of microbial communities depends on many factors including the local environment and the metabolic properties of the colonizing organisms. Chemical communications or other secreted factors also play a role and are used by different microbial strains both cooperatively and competitively. The spectrum of microbial secretions have various effects on the microbe's respective hosts, both positive and negative. Thus, characterizing the roles of microbial community members and their secretions can yield key mechanistic insights into microbiome function and can lead to new intervention strategies. Focusing on the simple, yet important functional impact of toxicity, we quantify supernatant dosage responses with image data and examine the morphological effects of microbial secretions on skin‐associated host cells. Since the diversity of microbial communities, coupled with the multiplicity of host tissues requires scalable methods, we develop and demonstrate a microfluidic device that enables high‐content screening of microbial secretion effects on adherent cell types.
