PROGRESSIVE STUDIES IN THE MOLECULAR PATHOLOGY OF EXPERIMENTALLY INDUCED HYPOTHYROIDISM AND EVALUATION OF PROTECTIVE ROLES OF SHILAJIT AND WITHANIA SOMNIFERA IN RATS

Endocrine disorders are widespread among Indian inhabitants and thyroid disorders represents an imperative subset of these endocrine disorders. Hypothyroidism is a clinical entity resulting from insufficient production or diminished action of either T3 and/or T4 thyroid hormones and high plasma levels of thyroid stimulating hormone (TSH). Hypothyroidism have relation with several system functions in the body which wind up in multiple organ defects in the affected species. The current study was conducted to appraise ameliorative effect of herbs, Withania somnifera and Shilajit either solely or in combination.
Monitoring Positive Mental Health in Swedish Adolescents: Psychometric Evaluation of the Mental Health Continuum – Short Form

BackgroundThe Mental Health Continuum – Short form (MHC-SF) is a self-report measure that has been increasingly used to monitor mental well-being at the population level. The aim of this study was to evaluate, for the first time, the psychometric properties of the MHC-SF in a Swedish population, more specifically adolescents. MethodsFirst, the evaluation was performed by examining face validity and test–retest reliability obtained in a pre-study (n = 93). Then using data from the Survey of Adolescent Life in Vestmanland 2020 (n = 3880; participation rate = 71%; females = 51%; mean age = 16.23 years), we performed confirmatory factor analysis on different factor structures based on theory and previous research. Model-based estimates were calculated for assessing the internal reliability of the factor structure with the best fit. Convergent validity was assessed by bivariate as well as model-based correlations, and test–retest reliability was evaluated by intra-class correlation coefficients. ResultsThis study on Swedish adolescents found that the MHC-SF is essentially unidimensional and best described with a bifactor model consisting of a dominant general well-being factor and three specific group factors of emotional, social and psychological well-being. Its overall reliability and the reliability of the general well-being factor were good to excellent, while the reliability of its subscales (specific group factor) was poor, and thus should not be used alone. Test–retest reliability of the total scale was good, and convergent validity was supported by strong to very strong correlations with the Short Warwick–Edinburg Mental Well-being Scale. ConclusionsIn conclusion, we consider the Swedish MHC-SF to be a psychometrically sound instrument for monitoring overall mental well-being in Swedish adolescents.
An improved feature matching ORB-SLAM algorithm

To solve the problems of low accuracy and poor real-time performance in traditional mobile robot vision simultaneous positioning and map construction (SLAM), the original algorithm was improved. First, the ORB features of adjacent images are extracted, and the PROSAC algorithm is used to achieve feature point matching. At the same time, the PROSAC algorithm is improved and optimized, and the execution time of the optimized PROSAC algorithm is significantly reduced; finally, based on the graph optimization model, a global Bundle Adjustment algorithm based on the largest common-view weight frame is proposed to achieve dense and sparse map creation. The algorithm is verified by Tum data set, and the experiment shows that the root mean square error has dropped significantly. The results on the data set effectively prove the effectiveness of the algorithm in this paper.
Prebiotic Food Intake May Improve Bone Resorption in Japanese Female Athletes: A Pilot Study

The aim of the present study was to clarify the influence of inulin and lactulose-fortified prebiotic food intakes on bone metabolism turnover among Japanese female athletes. The participants included 29 female athletes aged 18–25 years. They were requested to consume their habitual foods or drinks with one pack of prebiotic food every day for 12 weeks. Dietary intake, training time, body composition, blood sample, and fecal microbiota were assessed during this intervention period. Body composition, total energy intake, and training time of the participants revealed no significant changes during the intervention period. The occupation ratio of Bifidobacterium spp. was significantly increased at 3 and 4 weeks (18.0 ± 8.3% and 17.6 ± 8.5%, respectively) compared to that of pre-intervention (11.7 ± 7.3%) (p = 0.019 and p = 0.035, respectively). The serum TRACP-5b level was significantly decreased at 12 weeks (363 ± 112 mU/dL) compared to that at baseline (430 ± 154 mU/dL) (p = 0.018). These results suggest that the prebiotic food used in this study might have beneficial effects on bone health and gut microbial environment among female athletes. Further studies are warranted to identify the mechanism of the prebiotics–gut–bone axis.
Incidence of BCC in a Tertiary Care Hospital in Malwa region of Punjab

Objectives. Although the incidence of skin cancers in India (part of South Asia) is low, the absolute numberof cases may be significant due to large population. The existing literature on BCC in India is scant. So, thisstudy was done focusing on its epidemiology, risk factors, and clinicopathological aspects.Methods. A hospital based cross-sectional study was conducted in Punjab, North India, from 2017 to2019. History, examination and histopathological confirmation were done in all the patients visiting skindepartment with suspected lesions.Results. Out of 36 confirmed cases, 63.9% were females with mean ± SD age being years. Mean durationof disease was 4.7 years. Though there was statistically significant higher sun exposure in males comparedto females ( value being 0.000), BCC was commoner in females, explainable by intermittent sun exposure(during household work in the open kitchens) in women. Majority of patients (88.9%) had a single lesion.Head and neck region was involved in 97.2% of cases, with nose being the commonest site (50%) withnodular/noduloulcerative morphology in 77.8% of cases. Pigmentation was evident in 22.2% of casesclinically. Nodular variety was the commonest histopathological variant (77.8%). Conclusions. This study highlights a paradoxically increasing trend of BCC with female preponderance,preferential involvement of nose, and higher percentage of pigmentation in Indians.

Anxiety and Sleep Quality are Affected in Students from Social Sciences

Sleep quality in college students has been related to anxiety and depressive symptomatology. However, the available statistics have been focused on students from Health Sciences thus preventing to know whether the same problematic is observed in students from other Majors. We applied the scales DASS-21, PSQI, and EAT-26 to 80 Mexican undergraduate students enrolled to any of the first three semesters of Majors in Administration, Industrial Engineering, or Medicine. We report that the percentage of students with abnormal scores in anxiety (33.33%) and poor sleeping quality (71.43%) was higher in Administration students. By using a logistic regression model, we show that anxiety scores can be explained by stress level, poor sleep quality, depression scores, and by the Major of study. Our findings show that anxiety management is needed for students to alleviate other emotional affections and improve sleep quality, particularly for those of Social Sciences.

Luminescent and Transparent Wood Composites Fabricated by Poly(methyl methacrylate) and γ-Fe2O3@YVO4:Eu3+ Nanoparticle Impregnation

Natural wood is functionalized using the index matching poly(methyl methacrylate) (PMMA) and luminescent γ-Fe2O3@YVO4:Eu3+ nanoparticles to form a novel type of luminescent and transparent wood composite. First, the delignified wood template was obtained from natural wood through a lignin removal process, which can be used as a support for transparent polymer and phosphor nanoparticles. Then, the functionalization occurs in the lumen of wood, which benefits from PMMA that fills the cell lumen and enhances cellulose nanofiber interaction, leading to wood composites with excellent thermal properties, dimensional stability, and mechanical properties. More importantly, this wood composite displays a high optical transmittance in a broad wavelength range between 350 and 800 nm, magnetic responsiveness, and brightly colored photoluminescence under UV excitation at 254 nm. The unique properties and green nature of the luminescent wood composite have great potential in applications including green LED lighting eq.
Heavy Metals Biosorption by Copper Resistant Bacteria of Acinetobacter sp. IrC2

Heavy metal pollution is a serious problem because it cannot be degraded by natural processes and persist in soil, water, and sediment. Many indigenous microorganisms isolated from heavy metal contaminated sites had tolerance to heavy metals toxicity and could be used for bioremediation agent because of its capability to biosorb heavy metals. The aim of this research was to study the potency of copper resistant bacteria Acinetobacter sp. IrC2 as a biosorbent of heavy metals. Biosorption was determined by measuring the heavy metals concentration on growing medium by using atomic absorption spectrophotometer. The research showed that Acinetobacter sp. IrC2 was capable of growing in medium containing each of 2 mM of copper, zinc, lead, cadmium, and the mixture of those heavy metals. The addition of copper and lead in the medium changed morphological appearance of colonies to green and brown, respectively, suggesting that the survival mechanism of the isolate was by biosorbing copper or lead inside the cells. The percentage of heavy metals biosorption efficiency using live cells of Acinetobacter sp.IrC2 were up to 64.31% of copper, 24.73% of zinc, 62.79% of lead, and 11.56% of cadmium. Acinetobacter sp. IrC2 also reduced copper, lead, and cadmium concentration up to 24.30, 75.93, and 16.38%, respectively, in medium supplemented with 1 mM of the mixture of these heavy metals. The findings of this study indicated that Acinetobacter sp. IrC2 was a promising bacterium for removal of heavy metals.
Novel mathematical model to determine geo‐referenced locations for C‐ITS communications to generate dynamic vehicular gaps

: The study aims at determining geo-reference locations for dynamic cooperative communications to be established, allowing the generation of dynamic vehicular gaps between the Dangerous Goods Vehicles and their surrounding vehicles, such that they could travel via a tunnel as a platoon and in isolation. This will ensure the safety of other road users in line with check-and-allow procedures at the road tunnel on Trans-European Transport Network, as per ADR regulations. The model is verified for different road layouts approaching a road tunnel in the UK, using varying traffic scenarios to determine if the identified geo-referenced location by the model is at suitable distances for gap generation. The results are compared against the simulated real-world tunnel traffic flow with conventional vehicles involving escorting of Dangerous Goods Vehicles via human operators. The mixed traffic and connected vehicles traffic flow scenarios are simulated for dynamic gap generation and compared against real-world tunnel scenario to analyse the improvements in travel time, queues and congestion.
Observation of Slow Dynamic Exchange Processes in Ras Protein Crystals by 31 P Solid State

The folding, structure and biological function of many proteins are inherently dynamic properties of the protein molecule. Often, the respective molecular processes are preserved upon protein crystallization, leading, in X-ray diffraction experiments, to a blurring of the electron density map and reducing the resolution of the derived structure. Nuclear magnetic resonance (NMR) is known to be an alternative method to study molecular structure and dynamics. We designed and built a probe for phosphorus solid state NMR that allows for the first time to study static properties as well as dynamic processes in single-crystals of a protein by NMR spectroscopy. The sensitivity achieved is sufficient to detect the NMR signal from individual phosphorus sites in a 0.3 mm 3 size singlecrystal of GTPase Ras bound to the nucleotide GppNHp, that is, the signal from approximately 10 15 phosphorus nuclei. The NMR spectra obtained are discussed in terms of the conformational variability of the active center of the Ras ‐ nucleotide complex. We conclude that, in the crystal, the protein complex exists in three different conformations. Magic angle spinning (MAS) NMR spectra of a powder sample of Ras ‐ GppNHp show a splitting of one of the phosphate resonances and thus confirm this conclusion. The MAS spectra provide, furthermore, evidence of a slow, temperature-dependent dynamic exchange process in the Ras protein crystal. q 2002 Elsevier Science Ltd. All rights reserved
Factors Impacting Employee Absenteeism and The Managers’ Perception of its Causes in the Hotel Industry

The economic viability and success of a hotel depends on the optimisation of all resources, including Human Resources (HR). Absenteeism is an occurrence that can have a significant negative impact on optimising HR in South African hotels in the Gauteng Province. The objective of this study is to identify the factors that contribute to employee absenteeism, as well as describing the hotel employers’ perceptions of employee absenteeism. A quantitative research approach was followed in this study. A survey questionnaire was developed in order to collect data from 13 establishments, with a 3-star to 5-star grading, in the Gauteng Province. The findings reveal that absenteeism is mainly due to family responsibilities including childcare, other causes identified were strikes, fatigue, transport problem and genuine illness. It is evident from the findings that delivery of quality services can be affected negatively, due to abuse of sick leave and the cost associated with absenteeism. The results of this research project will contribute by creating an awareness of the negative impact that absenteeism has on the hotel and what employers could do to improve employee attendance.
The Effects of Water Levels and Interspecific Competition on Two Carex Species in a Temperate Wetland of Northeast China

Zonation along a water level is the main spatial distribution characteristic of wetland plants. This is mainly because of the influences of hydrological conditions and interspecific competition, which finally narrow the fundamental niche of a species to its realized niche. In the present study, a controlled experiment was conducted in order to analyze the relationship between Carex lasiocarpa/Carex pseudocuraica and Glyceria spiculosa, in conditions of three competitive treatments at four water levels. The results showed that in no competition, C. lasiocarpa preferred low water levels, but this preference receded when competing with G. spiculosa. In contrast, C. pseudocuraica had greater preference for low water level when competing with G. spiculosa. The root/shoot ratios of the two Carex species decreased with increasing water levels, but they were almost unaffected by different competition treatments. With the increase in water level during full competition with G. spiculosa, the competitive ability of C. lasiocarpa showed an increasing trend, whereas a contrary trend was observed in C. pseudocuraica. Our results suggested the effects of water levels and their interactions with interspecific competition varied between the two Carex species and played an important role in determining spatial distribution patterns and potential community succession of wetland plants.
Metastable Phase Equilibrium in the Aqueous Quaternary System (LiCl +MgCl2 + Li2SO4 + MgSO4 + H2O) at 308.15 K

Experimental studies on the metastable solubilities and the physicochemical properties including density, viscosity, refractive index, conductivity, pH value, and total dissolved salts (TDS) in the aqueous quaternary system (LiCl + MgCl2 + Li2SO4 + MgSO4+ H2O) at 308.15 K were determined with the isothermal evaporation method. According to the experimental results, the dry-salt phase diagram, water-phase diagram, and the physicochemical properties versus composition diagram were plotted. It was found that there are seven metastable crystallization fields corresponding to lithium sulfate monohydrate (Li2SO4·H2O, Ls), epsomite (MgSO4·7H2O, Ep), hexahydrite (MgSO4·6H2O, Hex), tetrahydrite (MgSO4·4H2O, Tet), bischofite (MgCl2·6H2O, Bis), lithium-carnallite (LiCl·MgCl2·7H2O, Lic), and lithium chloride monohydrate (LiCl·H2O, Lc), 11 univariant curves, and five three-salt cosaturated points of Ls + Ep + Hex, Ls + Hex + Tet, Ls + Tet + Bis, Ls + Bis + Lic, and Ls + Lic + Lc formed in the metastable quaternary sys.
Benefits of an intervention programme with racket sports in primary school students. Racket sports in elementary school students

This experimental study is aimed at implementing a one-month racket sports programme within a sample of students aged 9 to 13 years in order to analyze its motivational climate effects during physical education lessons in a primary school context. The intervention programme was carried out on 40 of the 285 participants, the rest of the sample were used for descriptive purposes. The subjects participated voluntarily and were randomly assigned to one of two groups: control (n = 20) and experimental (n = 20). The programme consisted of eight sessions of different racket sports (tennis, paddle, badminton and table tennis). Motivational climate was extracted from the “Questionnaire of Motivational Climate Perceived in Sport” (PMCSQ-2). PMCSQ-2 reported two dimensions, task and ego. Regarding the results obtained, no changes were found in the control group. However, in the experimental group there was a significant increase (P < 0.05) in the orientation towards the task (3.22 vs 4.36), leading to the detriment of the ego orientation (3.4 vs 2.25). Thus, racket sports activity seem to be adequate to change motivational orientation towards the task, which has been reported to increase intrinsic motivation and to reduce stress and anxiety in physical education lessons.

The removal of rhodamine B dye from aqueous solution using Casuarina equisetifolia needles as adsorbent

Abstract Casuarina equisetifolia needle (CEN), a lignocellulosic-rich and sustainable material, was used in order to investigate its ability as an adsorbent to remove rhodamine B (RB) dye from aqueous solution. Fourier Transform Infrared spectrometer was used to characterise CEN functional groups and scanning electron microscope was used to study its surface morphology. Batch experiments were done in order to determine the effect of some parameters such as adsorbent dosage, initial pH, contact time, ionic strength, temperature and initial dye concentration. Kinetics, isotherm modelling and thermodynamics studies were also performed in order to explore an insight into the mechanism of the adsorption process. The study showed that the adsorption of RB by CEN is endothermic in nature and follows the pseudo-second-order kinetics model. The Langmuir isotherm model fitted the experimental data best with a maximum adsorption capacity of 82.34 mg g−1.
The Impact of Absorptive Capacity on Innovation in Peru

This research aims to determine absorptive capacity’s impact on innovation in SMEs in Peru. SMEs in Latin America tend to be characterized by technological backwardness, and innovations, if any, tend to be incremental in nature. In Peru, more than half of innovation activities are destined to the acquisition of capital goods. In this sense, rather than generate innovation, SMEs tend to adopt existing innovations. Thus, in order to reap the benefits of innovation adoption, SMEs must possess a high degree of absorptive capacity, understood as the firm’s capacity to value external knowledge, assimilate, and exploit it towards commercial ends. In this respect, Innovate Peru, an innovation agency, grants subsidies to SMEs for facilitating innovation adoption. In collaboration between the public and academic sector, data was recollected from 88 SMEs that were granted this innovation subsidy. This paper contributes to the literature on absorptive capacity and innovation within Latin America, which has been vaguely studied. Likewise, it holds practical implications for top managers from SMEs who are looking to innovative, and policy implications for innovation policy makers, as it validates the effect of an innovation policy instrument.
How does focus-induced prominence modulate phonetic realizations for
 Korean word-medial stops?

Previous research has indicated that the patterns of phonetic modulations induced by prominence are not consistent across languages but are conditioned by sound systems specific to a given language. Most studies examining the prominence effects in Korean have been restricted to segments in word-initial and phrase-initial positions. The present study, thus, set out to explore the prominence effects for Korean stop consonants in word-medial intervocalic positions. A total of 16 speakers of Seoul Korean (8 males, 8 females) produced word-medial intervocalic lenis and aspirated stops with and without prominence. The prominence was induced by contrast focus on the phonation-type contrast, that is, lenis vs. aspirated stops. Our results showed that F0 of vowels following both lenis and aspirated stops became higher when the target stops received focus than when they did not, whereas voice onset time (VOT) and voicing during stop closure for both lenis and aspirated stops did not differ between the focus and no-focus conditions. The findings add to our understanding of diverse patterns of prominence-induced strengthening on the acoustic realizations of segments.
