Bioprospecting Fungal Glycosyl Hydrolases: Multi-locus Phylogenetic Analysis and Enzyme Activity Profiling for Enhanced Biomass Valorization

Lignocelluloses comprise of celluloses and hemicelluloses which can be effectively depolymerized to obtain fermentable sugars using diverse microbial enzymes, for subsequent conversion to various value-added products. Present study reports the bioprospecting of industrially significant microorganisms and their characterization to attain xylanases with high catalytic efficiency. Four potential xylanolytic fungi were identified through distinct primary and secondary screening process of 294 isolates from samples containing plant degrades. Morphological characterization and multigene analysis (ITS rDNA, 18S rDNA, nLSU rDNA, β-tubulin and actin gene) confirmed them Aspergillus niger AUMS56, Aspergillus tubingensis AUMS60, Aspergillus niger AUMS64 and Aspergillus fumigatus AUKEMS24 and their crude xylanase activities through submerged fermentation using corncob were 18.9, 32.29, 30.68 and 15.82 U ml-1, respectively. AUMS60 and AUMS64 have highest catalytic activity of 1429 U g-1 and 1243 U g-1, respectively, all having pH and temperature optima of 6.0 and 60°C respectively, where AUMS60 produced single xylanase (Xyn60; 36 kDa) and AUMS64 secreted 2 probable isozymes (Xyn64A and Xyn64B; 33.4 and 19.8 kDa). Maximum saccharification efficiency of AUMS60 and AUMS64 were 51.1% (13 h) and 52.2% (24 h) showing enhanced catalytic activity with various cations. Present research reports potential xylanases from indigenous fungi, providing opportunity for development of bio-catalysts concoction (novelty established) for enhanced saccharification of complex lignocelluloses finding specific industrial applications for production of value-added components.
Effect of Storage Time on the Physicochemical Properties of Waste Fish Oils and Used Cooking Vegetable Oils

Waste fish oils (FOs) and used cooking vegetable oils (UCOs) are increasingly becoming alternative renewable fuels. However, different physicochemical aspects of these renewable fuels, including the effect of storage, are not well-known. In this work, the effect of the storage period on physicochemical properties of selected samples of FOs and UCOs was investigated. The bio-oils were stored at 4 °C for up to five years before each experimentation. The chemical properties were characterized using capillary gas chromatography with flame ionization detection (GC-FID) and high-performance size exclusion chromatography including an evaporative light scattering detector (HPSEC-ELSD). Water contents and acid numbers of the bio-oils were determined using the Karl Fischer (KF) titration and the ASTM D 664 methods. Furthermore, the average heating values and surface tension of the bio-oils were determined. According to the results obtained, for all bio-oil types, the concentrations of polymerized triglycerides, diglycerides, and fatty acids and monoglycerides had increased during the storage periods. The physical properties of the bio-oils also showed a small variation as a function of the storage period. The overall results observed indicate that the deterioration of the physicochemical properties of bio-oils can be controlled through storage in dark, dry, and cold conditions.
Development of health-based environmental screening levels for insensitive munitions constituents

Abstract Dinitroanisole (DNAN), 3-nitro-1,2,4-triazol-5-one (NTO), and nitroguanidine (NQ) are constituents of insensitive munitions being developed to minimize the acute hazards associated with non-intentional detonation of warheads. Although a reference dose (RfD) has been established for NQ and occupational exposure levels have been developed for all three compounds, current state-of-the science methods were not used. Here we present the latest toxicity data and interpretations for NTO, DNAN, and NQ and use Bayesian Benchmark Dose modeling and a Bayesian approach to applying uncertainty factors to derive tolerable daily intake (TDI) values. A TDI of 0.02 mg/kg-d was calculated for DNAN based on extramedullary hematopoiesis in female rats. A TDI of 2.4 mg/kg-d was derived for NTO based on testicular toxicity in male rats. A TDI of 4.0 mg/kg-d was derived for NQ based on increased fetal resorptions in rabbits. These TDIs are generally an order of magnitude higher than previously developed reference values. These values can be used to inform public health, occupational safety, and product acquisition and stewardship decisions. Drinking water, soil, and tap water screening levels were derived for residential and worker exposure scenarios to help inform risk assessment decisions.

Safety Culture in the Spanish Nuclear Power Plants through the Prism of High Reliability Organization, Resilience and Conflicting Objectives Theories

Safety culture is the result of values, attitudes, and perceptions of the members of an organization that prioritize safety over competing goals. Previous research has shown the impact that organizational aspects can have in safety performance. Under the prism of the theoretical approaches from the high reliability organizations theory (HROT), resilience engineering (RE), and conflicting objectives perspective, this study was aimed at describing the overall main safety culture traits of the Spanish nuclear power plants, as well as identifying particularities associated with subcultures. For this purpose, a statistical analysis of safety culture surveys and behavioral anchored rating scales (BARS), handed over to all the operating Spanish nuclear power plants, was carried out. Results reveal that safety is a recognized value that prevails over production, there is a high degree of standardization, power plants are better prepared to organize plans and strategies than to adapt and cope with the needs of a crisis, and there is a critical and fragmented perception about the processes of resources allocation. Findings also identify that sociodemographic aspects, such as work location and contractual relationship, seem to be shaping differentiated visions. Several safety implications linked to the results are discussed.
Smooth Design of 3D Self-Supporting Topologies Using Additive Manufacturing Filter and SEMDOT

The smooth design of self-supporting topologies has attracted great attention in the design for additive manufacturing (DfAM) field as it cannot only enhance the manufacturability of optimized designs but can obtain light-weight designs that satisfy specific performance requirements. This paper integrates Langelaar’s AM filter into the Smooth-Edged Material Distribution for Optimizing Topology (SEMDOT) algorithm—a new element-based topology optimization method capable of forming smooth boundaries—to obtain print-ready designs without introducing post-processing methods for smoothing boundaries before fabrication and adding extra support structures during fabrication. The effects of different build orientations and critical overhang angles on self-supporting topologies are demonstrated by solving several compliance minimization (stiffness maximization) problems. In addition, a typical compliant mechanism design problem—the force inverter design—is solved to further demonstrate the effectiveness of the combination between SEMDOT and Langelaar’s AM filter.
Customer Behavior as an Outcome of Social Media Marketing: The Role of Social Media Marketing Activity and Customer Experience

Social media has been playing an important role in marketing strategy. As a part of social media, social networking sites (SNS) can be utilized by enterprises to create direct communication and good relationships with their customers. Therefore, enterprises using SNS have to select the right marketing content to enhance strong customer relationships, which lead to their behavior generating sustainable performance for enterprises. This research considered social media marketing activity (SMMA) and Customer Experience (CX) to measure the customer’s relationship quality, which can impact customer behavioral outcomes, which are purchase intention, loyalty intention, and participation intention. The 413 online questionnaire surveys were measured and analyzed using SmartPLS 3. The results show that SMMA and CX have a significant influence on the customer relationship quality, which also leads to a positive impact on customer behavioral outcomes. This research guides enterprises that SNS’s marketing content has to follow SMMA and CX dimensions to achieve the marketing objective and generate sustainable performance for enterprises.
Analysis of Online Classes in Physical Education during the COVID-19 Pandemic

Background and objectives: This study analyzed the effectiveness of the online practical classes (OPC) in physical education (PE) in compliance with the ADDIE model during the COVID-19 pandemic. Materials and Methods: Participants had no prior experience in OPC and total 75 participants were enrolled in this study. This study selected 15 universities in consideration of regional equality and randomly selected two professors and three students from each university. Results: (1) The learning interventions were not feasible for team projects. (2) In the implementation phase, most learners felt that errors persisted. (3) In the evaluation phase, educators reported unenthusiastic involvement of students and the learners were merely submitting assignments. (4) An appropriate level of the effectiveness through OPC showed significantly different between educators and learners. Conclusions: The findings indicate that timely and quality feedback should be provided for the successful execution of OPC in PE; the educators should prepare ahead and reduce technical errors and motivate learners continuously. Lastly, to prepare for the new normal after COVID-19, universities should provide enough time for educators to make OPC-videos and teach students in real time to ensure consistent feedback.
Perception of The Teaching of Pathological Anatomy by Students of The Faculty of Health Sciences of the University of Lomé, Togo 

Background: The aim of this study was to assess the perception of the students of the Faculty of Health Sciences of the University of Lomé on the teaching of Pathological Anatomy. Methods: This is an opinion survey carried out in 4 months at the University of Lomé among students of the faculty of health sciences (3rd in 8th year) on the perception of the teaching of Anatomy Pathological. The questionnaire was structured into 5 sections (socio-demographic, course organization, learning process, hospital internships, and general assessment) Results: A total, 395 students responded to the questionnaire. Their mean age was 24.04 ± 2.85 years and the sex ratio (M/F) was 2.4. They were mostly in 7th year of medicine (155). Regarding the course organization, 58.5% of the participants felt that the course objectives were often achieved and 51.6% said the course was well structured. For 49.9%, the important notions of the course were often sufficiently developed, and 55.2% affirm that the hourly volume was sufficient for the comprehension of the course. A statistically significant link was observed between the years of study and certain parameters of the learning process, namely: the adequacy between the theoretical course and the internships (p˂0.0001), the understanding of the course by the learning process (p˂0.0001), the essential documentation for the understanding of the course (p10.0001), the understanding of histological lesions through practical work (p˂0.0001). Concerning the general satisfaction of the course, they were 50.4% to be satisfied and 57.8% to wish a better organization of the courses and practical work. There is a statistically significant relationship between the degree of satisfaction with teaching and grade (p˂0.037). Conclusion: The teaching of pathological anatomy in its current form does not seem to provide the sufficient foundations and prerequisites desired by the students. It makes sense to strengthen their training through better organization of hospital internships and practical work, within the framework of the quality of teaching at the University of Lomé.
Do Regulations on Smoking Limit Cigarette Demand? An Empirical Evidence from Pakistan

Enacting Ordinance No LXXIV 2002, Pakistan has developed crucial anti-tobacco policies in the last two decades. We, therefore, examine in this paper effects of both price (cigarette taxation) and non-price (public regulations on cigarette smoking) anti-tobacco policies on cigarette demand. To accomplish this objective, we examine the short and long run dynamics of cigarette demand in Pakistan using auto-regressive distributed lag (ARDL) estimator covering the period 1981-2018 (annual observations). The study compares price elasticity estimated with and without regulations on cigarette smoking. The result obtained shows that when price increases by 10%, cigarette consumption decreases by 5% in the short run while it decreases by 6.9% in the long run. This finding confirms that cigarette demand model, in Pakistan, is in-elastic. More interestingly, the study finds that non-price regulations on smoking and cigarette demand have negative and statistically significant association. This finding confirms that non-price regulations influences the long-term dynamics of cigarette smoking in Pakistan. Furthermore, we obtain low price elasticity with non-price regulations and high price elasticity without non-price regulations while estimating cigarette demand equation. This empirical result is an evident of the fact that estimated cigarette price elasticity without incorporating non-price regulations into the demand model, are upward biased. The study therefore, concludes that smoking regulation policy based on overstated cigarette price elasticity would produce ambiguous outcomes. Hence, relying only on cigarette taxation (price policy) to regulate cigarette smoking would not produce desirable outcome. In addition, university education is positively and significantly associated with cigarette consumption. This finding show that our university education do not properly convey anti-smoking message to students. To reduce cigarette smoking, Pakistan will have to implement stronger, more comprehensive and better enforced non-price regulations along with taxes on cigarettes.
Effect of potassium on structural, photocatalytic and antibacterial activities of ZnO nanoparticles

ZnO and potassium doped ZnO nanoparticles were synthesized through wet chemical method. The samples were characterized by UV, XRD, SEM, TEM and EDAX. XRD analysis reveals that the prepared nanoparticles exhibit hexagonal wurtzite structure. TEM and SEM analyses disclose that synthesized samples were porous structure with needle shape. It also confirms that potassium was dispersed on ZnO surface. The influence of potassium on ZnO surface modulates the degradation of textile dyeing wastewater by improving its rate of decomposition to 0.007 min−1 with decoloration. A better zone of inhibition of about 20 mm against Staphylococci aureus and Pseudomonas aernginosa by ZnO and potassium doped ZnO nanoparticles were measured. The findings suggest that these nanoparticles have the potential to be a good photocatalyst and applied in water treatment to inhibit the bacterial growth.
Psychiatric Morbidities in Patients With Primary Headache

Background: Headache is a pain that occurs above the eyes or the ears, behind the head in the occiput or the cervical region of the neck. A primary headache is a type of headache that is caused by overactivity of, or the problems with pain-sensitive structures and is not a symptom of an underlying disease condition. This study highlights the association of Primary Headaches with psychiatric morbidities and stressful life events that may cause or increase its severity. Method: Descriptive, Cross-Sectional, Hospital Based study was done in 75 patients who met the diagnostic criteria for Primary Headache. Results: Patients presenting with primary headache were mostly from the age group of 26-30(26.7%). Most were female (57.3%) and 69.3% were married. 29.3% of the patients were housewives, 25.3% were into service and 21.4% were students. Anxiety and depression were the major diagnosis with 22.3 and 17.4 % respectively. Illness in the family and self or family member unemployment were the major stressful life events. There was a significant relation of Psychiatric Morbidity with Primary Headache. Conclusion: Anxiety disorder was the major psychiatric condition found in patients with Primary Headache followed by depression. Majority of this was seen in females, married and in the age group of 26-30 years. Thus it is necessary to screen Primary Headaches and reduce the stressful life events in these patients and limit the consequences and outcome of Primary Headache to prosper the health and living standard of the patients and the population as a whole.
Geochronology, geochemistry and zircon Hf isotope constraints on petrogenesis and tectonic setting of Early Permian volcanic rocks from Sonid Youqi area, Solonker Zone

ABSTRACT The mineral composition, whole-rock geochemistry, Sr–Nd isotopes, and in situ zircon U–Pb and Lu–Hf isotopes for mafic and intermediate-felsic volcanic rocks in the Sonid Youqi area were determined to unravel their petrogenesis and the Early Permian tectonic setting of the Solonker Zone, Central Asian Orogenic Belt. Zircon U–Pb ages suggested that these rocks formed in the Early Permian. The mafic volcanic rocks were depleted in Ba, Th, and Nb, enriched in Rb, U, and Sr, and had variable zircon εHf(t) values, with constant Th/Yb and variable Ba/La ratios, indicating that the mafic magma originated from the fluid-metasomatized mantle. The intermediate-felsic volcanic rocks were depleted in Ba, Th, Nb, Ta, and Ti and enriched in Sr, Zr, and Hf. Geochemical modelling and mineralogical observations suggested that magma mixing dominated the magmatic process. These features, along with variable SiO2 and MgO contents and zircon εHf(t) values of +9.40 to +13.47, suggested that these rocks originated from the mixing of melts from the mantle and juvenile crust. Early Permian volcanic rocks from the Solonker Zone had depleted Sr–Nd isotopic compositions, similar to those from the Japan Sea back-arc basin basalts. Their geochemical characteristics differed from those rocks formed during the initial subduction. In combination with previous studies, we suggest that the generation of these Early Permian rocks from the Solonker Zone occurred in an extensional tectonic setting that induced by the slab break-off of Hegenshan Ocean.
Labour market efficiency and emigration in Slovakia and EU neighbouring countries

Abstract Slovakia has experienced a six-year period of decreased labour market efficiency during a post-crisis period and growing emigration flows before and after a post-crisis period. There is also the concurrent issue of the lack of sufficient business activities in the southern, northern and eastern regions, and the economic development of some of the Slovak regions lacks diversification. We have analysed labour market conditions and emigration trends in Slovakia and EU neighbouring countries. The analysis of emigration trends has shown that among EU neighbouring countries, the Slovak migrant population tends to migrate mostly to the Czech Republic. We conducted regression analysis with the use of the ordinary least squares method to identify the main drivers affecting emigration from Slovakia to the Czech Republic as the primary destination country for Slovak migrants. The analysis has revealed that unemployment rates in both countries, labour market regulation which was introduced in the Czech Republic as well as EU enlargement in 2004 are the most significant triggers for emigration in Slovakia. Based on the results obtained, we have discussed possible ways to stimulate economic growth and prevent future emigration from Slovakia.
How Flexible Work Arrangements Affect Organizational Commitment, and Work-Life Enrichment in Pakistan’s Service Industry: The Role of Time Planning, Work-Life Conflict, and Engagement

Balancing work and life responsibilities is now encouraged, in organizations across countries and cultures. Moreover, amidst the current ‘pandemic’ status of widespread disease COVID-19, it becomes essential for businesses to operate remotely as many have started to. Flexible work arrangements (FWAs) are provided by organizations in response to these challenges. The purpose of this study is to focus on explaining how the usage of flexible working arrangements induce affective organizational commitment as well as helps to achieve Work-life Enrichment. For this, we proposed a theoretical framework hypothesizing that FWAs reduce work-life conflicts as well as make employees more engaged. The effect of FWAs on these two is also complemented by better time planning. Reduction of conflicts and enhanced engagement would in turn increase affective organizational commitment and Work-life Enrichment. Empirical validity was established by conducting a survey using a close-ended questionnaire. Data was collected from 300 service sector employees in Pakistan and analyzed using confirmatory factor analysis and structured equation modeling. The results suggested that flexible working arrangements are positively and significantly related to Affective Organizational Commitment, Employee Engagement, and Work-life Enrichment, whereas negatively and significantly affect Work-Life Conflict. Moreover, Employee Engagement also positively affects both enrichment and commitment. Surprisingly, Work-Life Conflict seems to positively affect Work-Life Enrichment. Time Planning seems to negatively complement the effect of FWAs on Work-Life Conflict whereas, positively affect Engagement. This study concludes that the positive attitudinal outcomes that are generated by simply providing flexible work options by incorporating more family-friendly policies, increase effectiveness, and business success continuity.
