Effects of lightning as a disaster in Himalayan region

In Nepal, the main disasters are floods, lightning, fire, epidemics, and landslides. Among the several disasters in the Himalayan region, lightning is an important one. Because of the short distance (about 160 km) between the low land and peak Mount Everest from South to North, there is a variation of about 950C temperature in these regions. The topographical features of the southern slopes and variation of temperature within this short distance influences the features of lightning and in this scenario, we get the positive cloud to ground lightning frequently which is more dangerous for human beings, animals, and property. In the Himalayan region, thunderstorms occur near the mountains due to which more positive charge can easily transfer from cloud to ground. Hence positive lightning occurs in the Himalayan region. The majority of the lightning-affected people are unaware of lightning safety and they should know the measures to protect life and property from lightning hazards. Hence by conducting awareness programs for the people of potential hazard areas, the number of injured people can be reduced as well as electrical, medical, military equipment can be somewhat protected from lightning.

DEVELOPING A SUSTAINABLE BUSINESS EXCELLENCE MODEL AND DISCUSSING KEY FACTORS

To achieve sustainable growth and maintain competitive advantages, many companies consider the sustainability of society and the environment, and adopt the business excellence (BE) framework of quality awards to promote total quality management (TQM) activities. This study used the Malcolm Baldrige National Quality Award’s (MBNQA) business excellence evaluation standard as the main body, supplemented by the Dow Jones Sustainability Indexes (DJSI). It proposed scoring criteria for the sustainable business excellence model, and discussed the degree of cause and correlation between evaluation criteria. The key factors were explored to provide companies with a reference for the pursuit of sustainable business excellence.
Optimal Placement of Unified Power Flow Controller by TOPSIS Method for Loss Minimization

In order to eliminate active and reactive power losses in the power system, this paper proposes TOPSIS and DE algorithm for determining the best location and parameter settings for the Unified Power Flow Controller (UPFC). To mitigate power losses, the best UPFC allocation can be achieved by re-dispatching load flows in power systems. The cost of incorporating UPFC into the power system. As a consequence, the proposed objective feature in this paper was created to address this problem. The IEEE 14-bus and IEEE 30-bus systems were used as case studies in the MATLAB simulations. When compared to particle swarm optimization, the results show that DE is a simple to use, reliable, and efficient optimization technique than (PSO). The network's active and reactive power losses can be significantly reduced by putting UPFC in the optimum position determined by TOPSIS ranking method.
Formation of droplets in weightless complex plasmas

Microparticles immersed in a low‐temperature plasma acquire strong negative charges and thus repel each other. Nevertheless, effective attraction between the microparticles in such a complex plasma can occur due to the interplay between the fluxes of plasma ions and the microparticles. Here, we report the observation of droplets formed in a complex plasma during a parabolic flight, and explain their formation in terms of the ion drag force that sustains the droplet. We have found a good agreement between the experimentally determined droplet size and its theoretical estimate using the ion drag force mechanism. Lower values of the electron temperature result in better agreement, as is consistent with the pulsed mechanism of discharge used experimentally.
Lubrication Analysis of a Cell Sliding into a Slit

The resistance to the blood cells at the entrance to pores and slits contributes considerably to the peripheral resistance in the blood circulation. This paper proposes, for the first time, a simplified mechanical model in an attempt to treat the motion of a cell sliding into a two-dimensional slit. In this model, the shape of the cell is taken as given according to the microvideograph and the cell membrane is assumed to slide over its surface. The lubrication theory is applied to the thin layers of plasma between the membrane and the slit wall, yielding the presure and shear stress distributions over the membrane as well as the resultant drag exerted on the cell. Our computations have simulated the process of the cell entering the slits, which is in qualitative agreement with the microvideographic observations.
Impact of polycyclic aromatic hydrocarbon exposure on cognitive function and neurodegeneration in humans: A systematic review and meta-analysis

Introduction This article documents an emerging body of evidence concerning the neurological effect of polycyclic aromatic hydrocarbon (PAH) exposure with regard to cognitive function and increased risk of neurodegeneration. Methods Two electronic databases, PubMed and Web of Science, were systematically searched. Results The 37/428 studies selected included outcomes measuring cognitive function, neurobehavioral symptoms of impaired cognition, and pathologies associated with neurodegeneration from pre-natal (21/37 studies), childhood (14/37 studies), and adult (8/37 studies) PAH exposure. Sufficient evidence was found surrounding pre-natal exposure negatively impacting child intelligence, mental development, average overall development, verbal IQ, and memory; externalizing, internalizing, anxious, and depressed behaviors; and behavioral development and child attentiveness. Evidence concerning exposure during childhood and as an adult was scarce and highly heterogeneous; however, the presence of neurodegenerative biomarkers and increased concentrations of cryptic “self” antigens in serum and cerebrospinal fluid samples suggest a higher risk of neurodegenerative disease. Associations with lowered cognitive ability and impaired attentiveness were found in children and memory disturbances, specifically auditory memory, verbal learning, and general memory in adults. Discussion Although evidence is not yet conclusive and further research is needed, the studies included supported the hypothesis that PAH exposure negatively impacts cognitive function and increases the risk of neurodegeneration in humans, and recommends considering the introduction of a variable “rural vs. urban” as covariate for adjusting analyses, where the neurological functions affected (as result of our review) are outcome variables.
“Books I Used as a Child were Mathematically Incorrect”: Reasons to Use Children’s Shape-Related Books as a Resource to Improve Mathematical Knowledge for Teaching

Some goals of mathematics teacher education include ensuring that pre-service teachers (PSTs) have strong content knowledge, the skill to anticipate and interpret student thinking, the ability to plan how to respond, and the ability to critically select resources for instruction. These goals are especially challenging for the topic of geometric shapes. Thus, we share an instructional activity that focuses PSTs’ attention on an inaccurate resource of geometric information, children’s books, to accomplish these goals in mathematics content as well as methods courses. Analyses of surveys and content assessments conducted to assess efficacy of the Shape Book Critique Activity were interpreted with the Mathematical Knowledge for Teaching (MKT) framework. Based on the findings we suggest that this short 40-minute activity is a promising way to promote PSTs’ growth in three aspects of MKT for geometric shapes.
Diversity of alien roadside herbs along an elevational gradient in western Mexico

Growing numbers of alien plant species threaten natural ecosystems worldwide. Mexico, as a megadiverse country, has lower numbers of alien species than other regions in America. However, there is a lack of information on the factors that determine the diversity patterns of alien species and their relative importance in the vegetation. The diversity of alien roadside herbs was analysed along an elevational gradient in western Mexico, including their relationship with environmental factors. Three hundred and seventeen herbaceous species were found in 37 sampling sites; 10% were aliens. The proportion of alien species in the ruderal herbaceous communities was lower than the average for this vegetation type in the country. Absolute species richness of natives was significantly and positively correlated with elevation. Absolute species richness of aliens was not significantly correlated with elevation, still; higher values were found at lower elevations. Generalised linear models for relative species richness and relative abundance of aliens with elevation had positive estimates near 0, which, though statistically significant, indicated a weak relationship. Other environmental co-factors, such as the distance to roads and highways, climatic variables, and disturbance indicators, were included in a random forest model. No clear correlation patterns were found. This seemingly random distribution of alien herbaceous plants in the region might be caused by the relatively recent introduction of most of the species. They have not yet had time to expand their distribution to their potential maximum. The early stage of the naturalisation process allows us to minimise the further spread of some species with targeted management and prevent them from becoming invasive.
Precise Evaluation of Gas–Liquid Two-Phase Flow Pattern in a Narrow Rectangular Channel with Stereology Method

The drive to increase the efficiency of processes based on two-phase flow demands the better precision and selection of boundary conditions in the process’ control. The two-phase flow pattern affects the phenomena of momentum, heat, and mass transfer. It becomes necessary to shift from its qualitative to quantitative evaluation. The description of the stationary structure has long been used in structural studies applied to metals and alloys. The description of a gas–liquid two-phase mixture is difficult because it changes in time and space. This paper presents a study of the precise determination of two-phase flow patterns based on stereological parameters analysis. The research area is shown against the flow map proposed by other researchers. The experiment was taken in the thin clear channel with dimensions of W = 50 × H = 1200 × T = 5 mm. The test method is based on the visualization of a two-phase air–water adiabatic flow pattern in the rectangular channel where superficial air velocities ranging from 0.006 to 0.044 m/s and the superficial water velocity ranged from 0.011 to 1.111 m/s. A high-speed camera was used for visualization. Images were analyzed with the use of stereological techniques. The study included the classification of structures according to generally accepted two-phase flow regime nomenclature for upwards co-current gas–liquid flow in a vertical rectangular channel. The result of the research was the determination of the stereological parameters’ changes with reference to the two-phase mixture flow hydrodynamics. The results were presented as waveform fluctuations in the values of stereological factors such as the volume fraction VV, interfacial surface SV, number of objects NV, mean chord l′m and the free distance λ. The description of how these parameters change with changes in phase fluxes is also presented. These waveforms help to distinguish the transient flow regimes, which allow for the automatic adjustment of the process stability. The authors found templates of the stereological parameters’ dependencies for flow pattern recognition. The research demonstrates wide possibilities of stereological methods’ application for the analysis of the two-phase gas–liquid process. The stereological model of two-phase pattern control enables the identification of process disorders.
Kretschmann-Based Optical Sensor via Thermally Tunable Refractive Index

This study discusses whether the prism used in a Kretschmann-based surface plasmon sensor can be fabricated from a thermotropic liquid crystal (TLC) material. The refractive index of the TLC prism can be thermally tuned to match the excitation requirements for the surface plasmon modes along the metal–TLC interface of the proposed sensing platform. The TLC material was chemically prepared in vitro and was thermally and optically characterized. The measurements reported a wide mesophase temperature range ΔT (~35 °C) and a relatively high clearing temperature TC (~84 °C) which constitutes a stable thermal control for the TLC optical parameters. The experimentally measured refractive indices of the TLC material reflect a linear change in line with the temperatures at several selected wavelengths in the visible region. A design of the surface plasmon sensor was proposed, which provided a linear response to the investigated analytes refractive index. This work highlights the importance of employing TLC material in designs compatible with detecting refractive index changes by thermal tuning and presents refractive index interrogation as an alternative method for exciting surface plasmon modes.
THE DIMENSIONS OF PSYCHOLOGICAL WELL-BEING OF CUSTOM EMPLOYEES DURING THE PANDEMIC

There has been a significant increase in interest about a psychological well-being among the researchers, politicians, media and general public. This study focuses on a measurement on a psychological well-being of the custom employees. For the purpose of measurement of a psychological well-being of custom employees, the authors have used Ruff’s scale that includes such components as positive relationships with others, autonomy, competence, personal growth, a purpose in life, and self-acceptance. According to Ryff (2014), well-being has been investigated in relation to one’s career pursuits. The purpose in life and personal growth were found to contribute to career commitments. In the case of the Latvian custom employees, among the essential elements of a psychological well-being are economic factors, favourable work environment and career opportunities in the organization. The study focuses in a psychological well-being of custom employees during the pandemic that leads to conclude that custom employees were in the forefront alongside with the doctors in stabilizing the situation in the county and have experienced a burn out, therefore they need a psychological support and a recognition of their efforts at work.
Innovative Coatings of Metallic Alloys Used as Bioactive Surfaces in Implantology: A Review

Metallic implants are widely used in the field of implantology, but there are still problems leading to implant failures due to weak osseointegration, low mechanical strength for the implant, inadequate antibacterial properties, and low patient satisfaction. Implant failure can be caused by bacterial infections and poor osteointegration. To improve the implant functionalization, many researchers focus on surface modifications to prepare the proper physical and chemical conditions able to increase biocompatibility and osteointegration between implant and bone. Improving the antibacterial performance is also a key factor to avoid the inflammation in the human body. This paper is a brief review for the types of coatings used to increase osseointegration and biocompatibility for the successful use of metal alloys in the field of implantology.
Directly grown monolayer MoS2 on Au foils as efficient hydrogen evolution catalysts

Synthesis of monolayer MoS2 is essential for fulfilling the potential of MoS2 in catalysis, optoelectronics and valleytronics, etc. Herein, we report for the first time the scalable growth of high quality, domain size tunable (edge length from ~ 200 nm to 50 {\mu}m), strictly monolayer MoS2 on commercially available Au foils, via a low pressure chemical vapor deposition method. The nanosized triangular MoS2 flakes on Au foils was proved to be an excellent electrocatalyst for hydrogen evolution reaction (HER), featured by a rather low Tafel slope (61 mV/decade) and a supreme exchange current density (38.1 {\mu}A/cm2). The abundant active edge sites and the excellent electron coupling between MoS2 and Au foils account for the extraordinary HER activity. Our work presents a sound proof that strictly monolayer MoS2 assembled on a well selected electrode can manifest comparable or even superior HER property than that of nanoparticles or few-layer MoS2 electrocatalyst.
Aerosol‐Assisted Chemical Vapor Deposition of Multi‐Walled Carbon Nanotubes on Steel Substrates for Application in Supercapacitors  

Carbon nanotubes (CNTs) are grown on to steel substrates by aerosol‐assisted chemical vapor deposition using ferrocene in ethanol as the carbon feedstock. The CNTs adopted a highly entangled morphology. Elemental analysis indicates that the main source of carbon for CNT growth is from the cyclopentadiene rings in ferrocene rather than the ethanol solvent. The CNT‐coated steel substrates are evaluated for their performance as supercapacitor electrodes. The electrodes exhibit a high geometric capacitance of 3.4 mF cm−2 which is due to the high internal surface area, but a relatively low specific capacitance of 0.34 F g−1.
Digital Pathways to Wellness Among Youth in Residential Treatment: An Exploratory Qualitative Study

Digital media use is central for youth as a means to facilitate identity development, social connection, and vocational competence. Emerging literature suggests that the influence of digital media use is more nuanced than the contemporary risk/benefit discourse, particularly for youth who experience social and emotional vulnerability. This youth-centered, developmentally informed study attends to the gap in literature addressing the digital media use experiences among youth in residential treatment (RT). McCracken’s Long Interview Method was utilized to conduct and analyze in-depth interviews with youth (n = 15) aged 13 to 18 in RT. The analysis involved movement from particular to general coding, applying categorical observations, and thematic comparison of transcripts. Consistent with existing literature on other youth populations, participants reported that digital media use had both beneficial and problematic implications for their well-being. Internet access decreased experiences of isolation and stigma and increased capacity to contend with marginalized identities (e.g., disability, Lesbian, Gay, Bisexual, Transgendered, Queer, Two Spirited Plus [LGBTQ2S+], child welfare guardianship). They reported that following an initial digital disconnect and stabilization, digital media use facilitated pathways toward agency, leadership, and community engagement (e.g., LGBTQ2S+ community, recovery blogs, animal advocacy). The findings suggest that supporting youth in RT to identify their online opportunities and needs can encourage individual growth, wellness, and participation in social change.
Multiplex Detection of Rotavirus A, B, C, Norovirus GI and GII, Adenovirus, Astrovirus and Sapovirus in a Single PCR System in Stool Samples From Children With Acute Diarrhea

We developed a RT-PCR combined with melting curve analysis (RRCMC) method for simultaneous detection of rotavirus A, B, C, norovirus GI and GII, adenovirus, astrovirus and sapovirus. Stool samples were collected from 160 children with acute diarrhea and tested by RRCMC assay. A total of 71 patients were tested positive with norovirus, adenovirus or rotavirus. The RRCMC assay has high specificity. There is no internal cross-reaction through the 8 diarrhea viruses and no cross-reaction of other commonly intestinal pathogens and human genome. The detection limit was ranging from 1×102 to 1×105 copies/ml for each diarrhea virus. In conclusion, the RRCMC method is a suitable rapid clinical test for infectious viruses, with the advantages of high-throughput, low cost, high sensitivity and specificity.
Reference Mapping Considering Swaps of Adjacent Bases

: Since the time of the HGP, research into next-generation sequencing, which can reduce the cost and time of sequence analysis using computer algorithms, has been actively conducted. Mapping is a next-generation sequencing method that identiﬁes sequences by aligning short reads with a reference genome for which sequence information is known. Mapping can be applied to tasks such as SNP calling, motif searches, and gene identiﬁcation. Research on mapping that utilizes BWT and GPU has been undertaken in order to obtain faster mapping. In this paper, we propose a new mapping algorithm with additional consideration for base swaps. The experimental results demonstrate that when the penalty score for swaps was − 1, − 2, and − 3 in paired-end alignment, for the human whole genome, SOAP3-swap aligned 4667, 2318, and 972 more read pairs, respectively, than SOAP3-dp, and for the drosophila genome, SOAP3-swap aligned 1253, 454, and 129 more read pairs, respectively, than SOAP3-dp. SOAP3-swap has the same functionality as that of SOAP3-dp and also improves the alignment ratio by taking biologically signiﬁcant swaps into account for the ﬁrst time.
Techno Economic Studies on the Effective Utilization of Non-Uniform Biowaste Generation for Biogas Production

Environmental effects from traditional energy sources and government regulations, necessitate the use of alternative energies like biogas for many uses including drying and refrigeration. Biowaste produced in educational institutions will not be uniform over the year. The non-uniform supply of biowastes, the absence of studies on bio digestion of likelihood biomass, the unreliability of energy from such conversion and the profitability of its usage in most applications are some of the factors to be considered while implementing this technology. In this regard, theoretical and experimental evaluations were carried out to accurately forecast biogas generation capabilities in educational campuses for obtaining biofuels with quantity and efficiency. It is observed that biogas generation with 52 to 58% methane content can be possible during an academic year. The quality of biogas shows that it is appropriate for almost any application. A broader analysis on different types of biogas digesters was conducted for their suitability in academic institutions. The economic benefits are analyzed for incorporating three biogas digesters namely KVIC, Fiber Reinforced Plastic (FRP) type and JANATA. There are some encouraging results to confirm the economic feasibility of biogas plants including positive net present value. Biogas generation with digesters of capacities varying between 25 and 450 cubic meter shows payback periods varies from 3.18 to 7.59 years, which confirms that it is profitable to use digesters in this range of capacities.
A novel variable step size least mean square method for adaptive micro-vibration control

The variable step size least mean square algorithm has been suggested since a number of years as a potential solution for improving the performance of least mean square algorithm. In this article, the variable step size least mean square algorithm is classified by the techniques which are used to update step size. Unfortunately, for variable step size least mean square algorithms with forgetting factor, a constant forgetting factor may slow down its convergence speed. For this reason, a variable forgetting factor method for variable step size least mean square is proposed in this article. First, the convergence analysis of a new variable step size least mean square algorithm with the variable forgetting factor is provided. Then, simulations expose the characteristics of this variable forgetting factor method. Last, a micro-vibration control experimental system is established. Four typical variable step size least mean square algorithms and their variable forgetting factor modified version are verified through experiments. The results show that the proposed variable forgetting factor method can effectively improve convergence speed while maintaining the steady-state performance of the variable step size least mean square algorithm with the constant forgetting factor.
