Rice husk char as a potential electrode material for supercapacitors
Authors: Nersu Venkata Naga Kanaka Suresh Kumar , Annepu Bhujanga Rao , Patcha Satya Srinivasa Babu , Rajaputra Subhakaran Singh
Published: April 2022

Rice husk char (RHC), a carbon-based material, was obtained by thermal decomposition of rice husk (RH) biological waste. Physicochemical properties of RHC were determined using XRD, FTIR, FESEM, TGA, N2 adsorption-desorption studies and contact angle mea­surement. A lab-scale supercapacitor (SC) was fabricated using as-prepared RHC and its super­capa­citive behaviour was investigated using techniques like CV, GCD and EIS studies. Each of RHC electrode showed a specific capacitance of 80.2 F g-1 at the constant charging/disharging current density of 0.05 A g-1. RHC exhibited 90 % retention of its initial capacitance even after 5000 GCD. The presence of amorphous SiO2 in RHC could contribute to the excellent wettability of RHC towards the water, enhancing its effective sur­face area by improving access of electrolyte ions into RHC. This remarkable super­capa­citi­ve performance of biological waste-derived RHC demonstrates its potential as a cost ef­fecttive and environ­mentally benign electrode material for aqueous electrolyte-based SCs.

Published: April 2022

Aim: The purpose of the present study was to evaluate the relationships between sprint mechanical parameters and sprint performance among female soccer players at different skill levels. The second objective was to assess a potential differences in force-velocity profiles between players from higher and lower sport skill level. Materials and methods: Sixty-six female soccer players (age = 23.1 5.1 years) performed a 30-m sprint to assess sprint performance and mechanical variables. Speed was measured by radar technology for 5, 10, 20, and 30 m and was used to calculate the theoretical maximal velocity (V0), theoretical maximal horizontal force (F0), maximal horizontal power (Pmax), decrease in the ratio of horizontal to resultant force (DRF), and peak ratio of horizontal to resultant force (RFpeak). Results: Different force-velocity (F-V) profile parameters are determinants of sprint performance at various distances. RFpeak (r =-0.99), Pmax (r = -0.93), and F0 (r = 0.92) had the strongest associations with sprint performance at shorter (5-m) distances, while at longer (20-m) distances, V0 (r = -0.73), Pmax (r = -0.94), and RFpeak (r = -0.88) were largely associated with sprint performance. The players from higher sports skill level showed higher levels of F0, RFpeak, Pmax and time to 10 meter distance. Conclusion: The results of this study suggest that depending on sprint distance used for testing and training procedures in female soccer players, the most informative parameters are Pmax, RFpeak, F0, and V0. As the skill level in female soccer players increases, an increase in maximal theoretical horizontal force during sprinting can be observed.

Published: April 2022

Big Data ist auf dem Vormarsch - und die Möglichkeiten für die Forschung scheinen endlos. Die grossen Datenmengen erlauben Analysen, die in der Vergangenheit nicht denkbar waren. Doch ernstzunehmende Probleme können entstehen, wenn basierend auf Korrelationen kausale Zusammenhänge postuliert werden, die vielleicht gar nicht bestehen. Wir stellen Experimente als Möglichkeit vor, um kausale Zusammenhänge zu erkennen und zeigen unterschiedliche Anwendungen der experimentellen Wirtschaftsforschung auf: Im Feld, im Labor und in einer Kombination der beiden. Schliesslich argumentieren wir, dass Big Data in Verbindung mit experimentellen Forschungsdesigns eine spannende Kombination darstellen kann.

High alpine sorcerers: revision of the cave wētā genus Pharmacus Pictet & de Saussure (Orthoptera: Rhaphidophoridae: Macropathinae), with the description of six new species and three new subspecies
Authors: Hegg Danilo , Morgan-Richards Mary , Trewick Steven A.
Published: April 2022

The New Zealand alpine cave wētā genus Pharmacus was first described by Pictet & de Saussure (1893) as a monotypic taxon. Three species were added to the genus by Richards in 1972. Here we clarify the status and appearance of all known species of Pharmacus. Based on morphology and mtDNA sequences we determine that the species Pharmacus brewsterensis Richards, 1972 is better placed within the genus Notoplectron Richards, 1964. We also resolve the species Isoplectron cochleatum Karny, 1935 and show that it belongs to the genus Pharmacus. Additionally, we describe six new species and three new subspecies from the southern regions of South Island, New Zealand. We provide key traits and known distributions for all known species and subspecies in this alpine genus. New combinations: Pharmacus brewsterensis Richards, 1972 becomes Notoplectron brewsterense (Richards, 1972) comb. nov.; Isoplectron cochleatum Karny, 1935 becomes Pharmacus cochleatus (Karny, 1935) comb. nov. New species and subspecies: Pharmacus cochleatus rawhiti subsp. nov., Pharmacus cochleatus fiordensis subsp. nov., Pharmacus cochleatus nauclerus subsp. nov., Pharmacus concinnus sp. nov., Pharmacus cristatus sp. nov., Pharmacus notabilis sp. nov., Pharmacus perfidus sp. nov., Pharmacus senex sp. nov. and Pharmacus vallestris sp. nov. New synonyms: Pharmacus dumbletoni Richards, 1972 = Pharmacus montanus Pictet & de Saussure, 1893 syn. nov.; Pharmacus chapmanae Richards, 1972 = Pharmacus cochleatus (Karny, 1935) syn. nov.

Published: April 2022

Settings Hemophilia is a coagulation disorder that occurs in one in 5000 male births. Patients with untreated severe hemophilia A have hemorrhagic complications, including joint bleeds and decreased survival. Emicizumab is a monoclonal antibody approved by the United States for routine prophylaxis of pediatric and adult patients with severe hemophilia A with factor VIII inhibitors. Objectives To perform a cost-effectiveness study of emicizumab prophylaxis for children and adults with severe hemophilia A compared with the current disease management in the Peruvian Ministry of Health and Social Security Health Insurance. Methods The patient transition between medical states was modeled with Markov methodology, and the lifetime costs and incremental effects of emicizumab compared to current management were estimated. The budgetary impact of emicizumab was estimated by projecting annual net costs and its five-year present value. Results In the Ministry of Health, emicizumab would generate savings between 14.6 and 16.0 per child and 11.8 per adult, in current US$ million. Social Security Health Insurance savings would be 12.8 to 14.9 per child and 40.1 per adult. In addition, this strategy would generate effectiveness gains, measured in quality-adjusted life-years, of 0.36 per child and 0.56 per adult and 0.25 per child, and 0.36 per adult in those respective institutions. The budgetary impact would be a net annual saving of 12.8 and 15.0 US$ million in those entities. Conclusions The current management of hemophilia A is very costly and has health outcomes inferior to those possible with emicizumab. This drug would produce significant savings and better patient health. The Ministry of Health and Social Health Insurance should implement hemophilia prophylaxis and treatment protocols and finance this drug.

Published: April 2022

Introduction COVID-19 has caused great fear on health professionals and could affect their mental health, therefore it is important to determine the association between the perception of risk to COVID-19 and mental health in workers of a Peruvian hospital. Methods Analytical cross-sectional study, through virtual survey. The dependent variables were: depression, anxiety and stress; The independent variable was perception of risk to COVID-19 and the covariates: sociodemographic, family, work and clinical data. Crude and adjusted prevalence ratios were found with a 95% confidence interval and a significance level of 5%. Results There was no association between risk perception and depression (adjusted prevalence ratio: 0.98 95% confidence interval: 0.89 to 1.08), anxiety (adjusted prevalence ratio: 0.94 95% confidence interval: 0.89 to 1.00), stress (adjusted prevalence ratio: 0.89 95% confidence interval 0.76 to 1.04). In the multivariate analysis, an association was found between depression with direct contact with the COVID-19 patient (adjusted prevalence ratio: 2.06, 95% confidence interval: 1.14 to 3.70) and with having a comorbidity (adjusted prevalence ratio: 2.56 95% confidence interval: 1.52 to 4.30); likewise, between anxiety with number of children (adjusted prevalence ratio: 1.09 95% confidence interval: 1.00 to 1.18), with direct contact with COVID-19 patient (adjusted prevalence ratio: 2.67 95% confidence interval 1.46 to 4.85) and having comorbidity (adjusted prevalence ratio: 2.00 95% confidence interval: 1.40 to 2.86); finally, between stress with direct contact with the COVID-19 patient (adjusted prevalence ratio: 2.86, 95% confidence interval: 1.20 to 6.83). Conclusions No statistically significant association was found between risk perception and depression, anxiety, or stress. However, there was an association between depression, anxiety, and stress, each with direct contact with COVID-19 patients; between anxiety and depression, each with having comorbidities and, finally, anxiety with the number of children.
CHARASTERISTICS OF THE EARLY WARNING SYSTEM ON STRATEGIC RISKS IN INTERNATIONAL BUSINESS OPEREATIONS
Authors: Kereta Josip , Primorac Dinko , Mikić Mihaela
Published: April 2022

This paper aims to establish the level of development of the early warning system used in the business risk management system with special emphasis on strategic risks. The sample of research consists of Croatian companies that operate within the international market. The constructed model of the early warning system should indicate opportunities and threats and should also enable the consideration of the positive and negative dimensions of risk. The primary survey was conducted using a structured questionnaire through the Google Forms platform and using the Likert scale with a scale of 1-5, where (1) is “I completely disagree” and (5) “I completely agree”. In data analysis, the Hi-square method is used, which is the most applicable non-parametric method of quantitative data analysis. The survey collected 120 responses. All four tested hypotheses have been confirmed, allowing for the following conclusions: First, an early warning system which is properly modeled and operationalized allows for predicting future business events. Second, this early warning system should be focused on the possibility of taking advantage of strategic opportunities and, third, avoiding strategic threats. Fourth, this system should be located within the organizational unit Controlling. A properly modeled and operationalized early warning system for strategic risks arising in international business should also contain the following elements: holding regular meetings, regularly using and implementating of SWOT analysis, analyzing the external environment, monitoring and obtaining information on the technological environment, regularly using and conducting PESTLE analysis, regularly using and implementing Porter’s five-force model, monitoring and obtaining data on the economic environment, and using the services of various professional associations and institutions. Observing current events, analyzing past events, and assessing events and future changes makes it easier to evaluate the early warning system, therefore determining whether it detected any changes that further affected fluctuations in the economic and social environment. This approach formulates the basis for avoiding risk and its negative consequences that may arise as a result of unexpected changes.
STRATEGIC RESTRUCTURING OF ENTERPRISES IN CRISIS SITUATIONS – COMPARATIVE ANALYSIS OF BOSNIA AND HERZEGOVINA AND THE EU
Authors: Milovanović Dragan
Published: April 2022

Business failure and poor business results over a long period of time represent a sure path to crisis. In such conditions, the postulates of the so-called crisis management (Crisis management) are accepted as a necessity and the need for strategic restructuring imposes in the long run. Managers are often not able to recognize the symptoms and causes of the company’s crisis in time. This leads to a weakening of the business performance and business results of the company and eventually to the company’s entry into the business crisis. The strategic approach to restructuring encompasses a broader aspect of the activities that need to be carried out in order for a company to emerge from the crisis, survive and thrive. Which restructuring strategies to apply in times of corporate crisis largely depends on the current position of the company, goals, needs and ways out of the crisis. Also, we tested the statistical impact and comparison, types of restructuring of large enterprises in Bosnia and Herzegovina in relation to European Union enterprises. The results showed that our managers understand the importance of a strategic approach to corporate restructuring. In this respect, we do not statistically differ significantly from the countries of Western Europe, Central Europe, Eastern Europe, and Serbia.

Published: April 2022

The issue of the evaluation of trade efficiency based on multi-criteria analysis is very current, complex and significant. It provides a basis for improving, by applying adequate measures, the efficiency of trade in the future. With this in mind, this paper analyzes the efficiency of Serbian trade based on the COPRAS method. The obtained results of the empirical research of trade efficiency in Serbia using the COPRAS method show that it was best in 2020. Recently, the efficiency of trade in Serbia has been continuously increasing. This was positively influenced by numerous factors: economic climate, living standard, employment, inflow of foreign direct investment (global retail chains), modern concepts of cost and business management, digitalization of all business, electronic sales. The negative impact of the Covid-19 corona virus pandemic on trade efficiency in Serbia is negligible (compared to other economic activities, for example, Tourism and hospitality), and is partially offset by increased online sales.
Ortega sobre el amor. Un diálogo con Victoria Ocampo
Authors: Díaz Freire José Javier
Published: April 2022

In the inter-war period, Ortega y Gasset set out to construct a new modernity in which love disappeared. He established a close link between modernity and the regulation of amorous emotion, and between the latter and gender relations. The centrality of love in Ortega’s project of rectifying modernity explains the abundance of his writings on the subject, many of these addressed, somewhat veiled, to Victoria Ocampo. There are hardly any studies on Ortega’s writings on love and none at all from a gender perspective. This article is also in keeping with the growing interest in the topic of love in the field of gender studies.
Factors Affecting Environmental Performance during the Covid-19 Period in the Leather Industry: A Moderated-Mediation Approach

Published: April 2022

Like many different and relevant sectors, the leather industry is currently facing a major environmental issue that may affect the competitiveness of all the stakeholders across the value chain. Drawing the conceptual model on the natural resource-based view (NRBV), this study seeks to examine the mediating role of individual green values (IGV) between green transformational leadership (GFTL) and environmental performance (EP). Furthermore, government regulations are used as a moderator concerning the relationship between GTFL and EP. An online survey was randomly distributed to Pakistan's leather industry employees to test the hypothesis by collecting data from 205 respondents. Partial Least Square Structural Equation Modeling (PLS-SEM) has been used to analyze data. The results demonstrate that green transformational leadership (GTFL) positively affects EP. Moreover, this study also reveals that GTFL significantly contributes to developing the IGV that consequently affects EP. Thus, the current study provides a significant sequential GTFL, IGV and EP path. However, surprisingly, the results show that government regulations do not moderate the relationship between GTFL and IGV. This study significantly contributes to the theory and stakeholders and leaders in a vast variety of manufacturing industries. It suggests that all organizations should adopt GTFL principles that encourage employees to engage in environmentally friendly activities by developing green values at the individual level to enhance EP. With this regard, GTLF, IGV, and government regulations may thus play a vital role for organizations and industry for better EP and competitiveness.

Published: April 2022

Foreign direct investment (FDI) is an extremely important factor that promotes national competitiveness and economic development through technology transfer, new management skills, foreign trade, corporate productivity, etc. This study aims to analyze the significance of FDI and its impact on tax revenue and competitiveness, focusing on the European Union (EU) economy. An empirical analysis is conducted to determine the relationship between inward and outward FDI and tax revenue by employing data on EU countries between 1999 and 2019. The data were extracted from the United Nations Conference for Trade and Development (UNCTAD) database and the World Development Indicators database (WDI) of the World Bank. To fulfill the objective of this study and to determine the effect of FDI on tax revenue, an econometric model was developed. The research methods include systematic and comparative analysis of scientific literature, panel data analysis, and multiple regression analysis. The regression analysis was based on the least-squares method, and the estimates of the econometric models were calculated by identifying robust heteroscedasticity-consistent standard errors. The study results reveal that the outward FDI has a significant stimulating impact on total tax revenue. In contrast, inward FDI has a dampening effect on tax revenue. The analysis of the lagging effect of FDI on tax revenue in the EU member states revealed a statistically significant lagging impact of the outward FDI made two years before. The estimations indicate that the lagging effect is an incentive. No statistically significant lagging effect of the inward FDI flows on tax revenue was found.

Published: April 2022

The aim of this paper is to study the convergence patterns in the European Union and the Euro Area between 2000 and 2019 by means of the absolute and conditional β- and σ-convergence, considering cohesion not opposite but complementary to competitiveness. By estimating cross-sectional regressions, we have found evidence favouring the absolute β-convergence for the Eurozone (19) and the European Union, illustrating that the initially poorer members experienced higher GDP per capita growth rates than the developed economies. The average catching-up speed recorded between 2000 and 2019 in the European Union was 2.5%, while in the Eurozone (19), it was 2.3%. Based on panel data and seemingly unrelated regressions, we have illustrated that improvement in the competitiveness of Member States by promoting investment, trade openness, high levels of labour productivity, education and the implication of citizens in society positively influenced the GDP per capita growth rates between 2000 and 2019. Finally, the estimation of σ-convergence based on the standard deviation led us to conclude that income gaps narrowed across the European Union and the Eurozone (19) between 2000 and 2019, having, in contrast, an upward trend among the early adopters of the euro. The original elements of the paper derive from the comparative analysis of convergence in the Euro Area and the European Union and the study of the economic growth process from the perspective of competitiveness-related variables. In this respect, the study emphasizes the role of human capital in generating prosperity gains at the Community level.
Montreal Cognitive Assessment (MoCA) performance in Huntington’s disease patients correlates with cortical and caudate atrophy
Authors: Ramirez-Garcia Gabriel , Galvez Victor , Diaz Rosalinda , Campos-Romo Aurelio , Fernandez-Ruiz Juan
Published: April 2022

Huntington’s Disease (HD) is an autosomal neurodegenerative disease characterized by motor, cognitive, and psychiatric symptoms. Cognitive impairment develops gradually in HD patients, progressing later into a severe cognitive dysfunction. The Montreal Cognitive Assessment (MoCA) is a brief screening test commonly employed to detect mild cognitive impairment, which has also been useful to assess cognitive decline in HD patients. However, the relationship between MoCA performance and brain structural integrity in HD patients remains unclear. Therefore, to explore this relationship we analyzed if cortical thinning and subcortical nuclei volume differences correlated with HD patients’ MoCA performance. Twenty-two HD patients and twenty-two healthy subjects participated in this study. T1-weighted images were acquired to analyze cortical thickness and subcortical nuclei volumes. Group comparison analysis showed a significantly lower score in the MoCA global performance of HD patients. Also, the MoCA total score correlated with cortical thinning of fronto-parietal and temporo-occipital cortices, as well as with bilateral caudate volume differences in HD patients. These results provide new insights into the effectiveness of using the MoCA test to detect cognitive impairment and the brain atrophy pattern associated with the cognitive status of prodromal/early HD patients.
Biochemical composition and function of subalpine shrubland and meadow soil microbiomes in the Qilian Mountains, Qinghai–Tibetan plateau, China

Published: April 2022

Microorganisms participate in the soil biogeochemical cycle. Therefore, investigating variations in microbial biomass, composition, and functions can provide a reference for improving soil ecological quality due to the sensitivity of microorganisms to vegetation coverage changes. However, the differences in soil microorganisms between shrubland and meadow have not been investigated in ecologically vulnerable subalpine areas. This study aimed to investigate the biochemical composition and functions of the soil microbial community under two shrublands and a meadow at high altitudes (3,400–3,550 m). Three sites under two shrublands,Rhododendron thymifolium(RHO) andPotentilla fruticosa(POT), and one meadow dominated byKobresia myosuroides(MEA), were selected on the southern slope of the Qilian Mountains on the northeastern edge of the Qinghai–Tibetan Plateau, China. Soil physicochemical properties, the microbial community composition expressed by the phospholipid fatty acid (PLFA) biomarker, and enzyme activities were analyzed as well as their relationships. The results showed that water holding capacity and the soil carbon, nitrogen, and potassium content in RHO and POT were higher than those in the MEA. Moreover, the soil active carbon, dissolved organic carbon, total nitrogen, and dissolved total nitrogen content in RHO were higher than those in POT. The abundance of total PLFAs, bacteria, and fungi beneath the shrublands was considerably higher than that in the MEA. The PLFA abundance in RHO was significantly higher than that in POT. The fungal-to-bacterial ratio of RHO and POT was significantly higher than that in the MEA. The activities of β-glucosidase, cellobiohydrolase, and leucine aminopeptidase were the highest in RHO among the three vegetation types, followed by POT and MEA. The redundancy analysis indicated that the biochemical composition of the soil microorganisms and enzyme activities were driven by total nitrogen, dissolved organic carbon, water holding capacity, and soil organic carbon. Therefore, shrublands, which have higher biomass, can improve soil moisture status, increase soil carbon and nitrogen content (especially active carbon and active nitrogen), and further increase the abundance of total PLFAs, bacteria, and fungi. The increase of microbial biomass indirectly enhances the activity of relevant soil enzymes. The variations in PLFA abundance and enzyme activities can be attributed to shrub species, especially evergreen shrubs, which create more favorable conditions for soil microorganisms. This study provides a theoretical basis for investigating the soil biogeochemical cycle and a scientific basis for soil management and vegetation restoration in the subalpine regions.

Published: April 2022

The production of the underutilised legumes in Nigeria is at a very low ebb, attempt to increase its production requires adoption of improved technologies on the crops. Hence, Information channels for technology adoption among farmers who cultivate underutilised legumes in Oke-Ogun area of Oyo State was therefore investigated. A multi-stage sampling procedure was used and 75 respondents were selected through snowball technique. Results indicate that 49.3% of farmers were above 50 years, majority were male (81.3%),married (76.0%) and educated (67.6%). Majority of the respondents had high access to radio (\(\bar{x}\) =1.81) and farmers’ association (\(\bar{x}\) =1.41) for information on underutilized legumes and preferred radio (\(\bar{x}\) =0.93) and extension agents (\(\bar{x}\) =0.92) as major sources of information dissemination. Poor seed viability (\(\bar{x}\) =1.78 ) and poor yield (\(\bar{x}\) =1.77 ) were the major constraints limiting production of underutilised legumes in the study area. There was significant relationship in the respondents’ educational status (χ2 =10.363; p=0.016) and information channels for technology adoption among farmers who cultivate underutilised legumes. It is recommended that research institutes should carry out studies with a view to generate technologies that would alleviate constraints faced by farmers in the production of lesser legumes.

Published: April 2022

Vegetable producers are often less knowledgeable about pest and disease identification, pesticide doses, application times, and health impacts of pesticides. As a result, it was thought that the research would be very useful in determining the level of perception of safe plant protection techniques among vegetable producers. The study was conducted in Prayagraj District of Uttar Pradesh to measure the awareness of safe plant protection measures among the vegetable growers in Prayagraj district of Uttar Pradesh. A total number of 120 respondents were selected randomly from ten villages under Chaka block because productivity, production and area under vegetable cultivation were found to be maximum. The data were collected by personnel interview method by using pre structured interview schedule and descriptive research design was used for this study. The findings of the study revealed that 47.50 per cent of the respondents belonged to the middle- aged group, majority of the respondents (55.84%) belong to the OBC caste and majority of the respondents belongs to medium level of annual income i.e. 50,000 – 1 lakh. The findings also revealed that 49.16 per cent of the respondents had medium level of awareness towards safe plant protection measures followed by 23.34% and 27.50% of the respondents with low and high levels of awareness respectively. It was found that independent variables like age, caste, economic motivation were positively and significantly correlated with awareness of safe plant protection measures. It is suggested that government should organized awareness camps, campaigns and demonstrations about safe plant protection measures.

Introduction: In the developing nations, neonatal sepsis account for the larger portion of the neonatal morbidity and mortality. Blood culture is considered as the gold standard for the diagnosis. Both, the conformation and management is difficult for clinicians in the resource limited nations like Nepal.

Method: It is a retrospective observational study conducted at one of the tertiary care hospital in eastern Nepal over a year.

Result: Incidence of neonatal sepsis was 12.9%. The incidence of blood culture positivity in the neonatal sepsis was 15%. Coagulase negative Staphylococcus species and Escherichia coli were two most predominant organism isolated. All of the isolated Klebsiella spp. and Pseudomonas spss.showed resistance to ampicillin whereas 100% of Coagulase Negative Staphylococcus spp. showed sensitivity to vancomycin.

Conclusion: Isolated bacteria showed resistance to multiple antibiotics. This is an alarming moment for the pediatrician. Antibiotics should be used judiciously and continuous surveillance should be done to monitor the changing epidemiology of organisms and antibiotic sensitivity as the emergence of resistance to commonly used antibiotics is high.

Authors: Nnenna Ajibo Doris , Cynthia Ekenna Ifeoma
Published: April 2022

Obesity is a metabolic disease caused by a large buildup of fat in the body and a deficit in energy consumption compared to energy disposal. It has been related to a shorter life expectancy, has been connected to various cancer types, and has been linked to secondary metabolic illnesses such as diabetes, atherosclerosis, and hypertension. Due to an increase in white adipose tissue deposition, oxidative stress can lead to obesity, and obesity can lead to increased oxidative stress in the body. Coenzyme Q10 (Ubiquinone) is an endogenous anti-oxidant with anti-oxidant properties that aids to reduce oxidative stress. It boosts the anti-oxidant activity of superoxide dismutase and glutathione peroxidase, reduces lipid peroxidation, neutralises free radicals, and promotes vitamin E and C regeneration in the body. It can be found in the form of ubiquinol or ubiquinone. CoQ10 may be found in both diet and supplements. It can be made as a syrup, tablet, soft gel capsule, hard shell capsule, or oral powder as a supplement. It is classified as a biopharmaceutical class II compound with low solubility but good permeability. When CoQ10 supplement is taken with a fatty meal, its bioavailability is increased. CoQ10 slows the evolution of obesity-related atherosclerosis and helps to mitigate the harmful bodily environment caused by obesity.

Shelf life of potato is highly variable depending upon various factors including nitrogen application and storage conditions. The perishable nature of potato tubers necessitates the study of factors affecting tuber post- harvest life. Objectives of this experiment were to study the influence of nitrogen doses on storage parameters of different potato varieties, viz., physiological loss in weight, decay loss and sprouting. The treatments consisted of four doses of nitrogen (control, 80, 160, and 240 kg ha-1) and three potato cultivars viz., Kufri Pukhraj, Kufri Gaurav and AICRP-P-39. After harvesting potatoes from the field, the tubers were cleaned and stored using a complete randomized design (CRD) and three replications, in a well-ventilated room for three months to assess their shelf life. The field application of 240 kg nitrogen per hectare resulted in the poor shelf life of tubers as compared to the ones grown under lower doses. However, the superior shelf life of potato tubers was observed under control during the whole storage period. Among the cultivars, Kufri Pukhraj had better storage quality than Kufri Gaurav and AICRP-P-39. Thus, to obtain maximum shelf life of potato tubers, the variety Kufri Pukhraj with no application of nitrogen is advisable.

Background: Multiple sclerosis (MS) has been reported to be associated with psychological manifestations like depression, anxiety, and depression. Its presence in university students may impact their academic performance. As the relapsing-remitting type (RRMS) is the commonest MS type, we conducted this study to evaluate the prevalence and severity of the previous psychological manifestations in University students diagnosed with RRMS. The impact of MS on their academic performance was also assessed.

Patients and Methods: This case-control study included 65 students diagnosed with RRMS in addition to the same number of healthy controls. Psychological manifestations were evaluated via the Arabic form of DASS (depression, anxiety, and stress score), while academic performance was assessed via the GPA (grade point average).

Results: Patient criteria, including age and gender, were statistically comparable between the two groups. The three components of DASS expressed significantly higher values in cases compared to controls, indicating increased prevalence and severity of psychological issues in association with RRMS. MS was associated with a significant decline in the student’s academic performance as had median values of 1 and 3 in cases and controls, respectively.

Conclusion: MS is associated with a significant increase in both prevalence and severity of depression, anxiety, and depression compared to the normal healthy population. MS also has a significant negative impact on the academic performance of these students.

Heavy metals contribute to soil contamination and can decrease soil productivity. Compost and Ca(OH)2 can restore heavy metal contaminated soil. The purpose of this study was to examine the effectiveness of compost and Ca(OH)2 in reducing cadmium (Cd) contamination in Inceptisols. The study was carried out between February and April of 2021. The study used a completely randomized design (CRD) with treatments of control (0), Ca(OH)2 at a dose of 1 ton/ha, 2 tons/ha, 3 tons/ha, and compost at a dose of 10 tons/ha, 20 tons/ha and 30 tons/ha. Each treatment was repeated three times. The results showed that the treatment had a significant effect on soil pH, organic C, N-total, and soluble Cd in the soil. The highest dose of compost and Ca(OH)2 is equally effective to lower the concentration of Cd in contaminated Inceptisols. This finding is significant in the restoration of Cd contaminated soils.

Local varieties of cowpea are promising for breeding programs, as they harbor an important source of genetic variability. The objective of this study was to estimate the genetic variability among cowpea genotypes based on morphological and agronomic descriptors. The experiment was carried out in a randomized complete block design with three replications in the experimental field at Universidade Federal do Acre, in Rio Branco, Acre, Brazil. The experimental unit consisted of six lines of 5.0 m, with a spacing of 0.80 m x 0.50 m, with the four central lines used in the evaluations of 21 characters. The treatments consisted of seven local cowpea genotypes. The Mahalanobis generalized distances (D2) were calculated and used in the Tocher and UPGMA clusters. Principal component analysis, relative contribution of traits and analysis of variance were also performed. Manteiguinha and Mudubim de Rama were the most dissimilar genotypes, while Ceará Mercado and Baiano were the most similar. The main component of greater explanation illustrated the separation of genotypes into two groups, with the union between Manteiguinha and Manteigão forming one group and the other genotypes forming the other group. The traits grain yield, number of grains per pod and grain mass of fifty pods were the main determinants in the quantification of genetic divergence. The combination of the Manteiguinha with Mudubim de Rama genotypes is the most suitable for obtaining promising segregating populations.
