Contributions of working memory and inhibition to cognitive flexibility in Nigerian adolescents
Authors: Nweze Tochukwu , Nwani Wisdom
Published: December 2019

This study used a novel approach that combined the latency and accuracy scores to examine the relative involvement of inhibition and working memory in two measures of cognitive flexibility - mixing cost and switch cost in 110 Nigerian adolescents. Results showed that inhibition was significantly associated with switch cost. On the other hand, working memory was negatively associated with mixing cost. These findings support the assumptions that cognitive flexibility skills are dependent on inputs from inhibition and working memory processes. Inhibition is involved in the deactivation of irrelevant stimuli during switching trials while working memory is essential to maintain the current rule in sets that require no shifting.

Published: December 2019

The objective of this research is to employ the natural dyes in dye-sensitized solar cell (DSSC). On account of eco-friendly, renewable, and non-hazardous properties of natural dyes over silicon, a semiconductor, photo-sensitizer in conventional solar cells,  cyclohexane extract of Terminalia alata, a natural dye, was employed as photo-sensitizer. The photoanodes ZnO and 5% Al-doped ZnO for DSSCs were developed by spray pyrolysis. The X-ray diffraction (XRD) has shown hexagonal wurtzite structure of ZnO with lattice constants a = 3.2487 Å and b = 5.1518 Å having particle size 25.85 nm for ZnO and 33.17 nm for Al-doped ZnO. The DSSC properties such as solar conversion efficiency (η), short-circuit current density (Jsc), open-circuit voltage (Voc), and fill factor (FF) were found to be 0.31%, 2.10 mA/cm2, 0.73V, and 45% for ZnO photoanode and 0.37%, 2.25mA/cm2, 0.70 V, and 52.10% for 5% Al-doped photoanode respectively.

Published: December 2019

The suspended particle aerosols especially anthropogenic are recognized to have degradation in the quality of the atmosphere and one of the factors to cause uncertainty in climate. In this paper, we have investigated the trend of the parameter ‘Aerosol Optical depth’ and by application of spectral based wavelet analysis; we extracted spatial and temporal variation over the selected AERONET sites of Nepal. We have taken the site Kyanjin_gompa, Lumbini, Pokhara and Kathmandu under the consideration of our study because of their geographical variability which is a significant factor for causing variation in local as well as global circulation of aerosols. As per data retrieved from Ground-Based remote sensing system for the year 2018 over the site Kyanjin gompa, Lumbini and Pokhara and for the year 2016 over the Kathmandu, we extracted the periodicity and frequency of the variation in AOD for each site by the application of continuous wavelet analysis on AOD at three different wavelengths. On reviewing the previous studies, it is seen that the area lying at the Indo-Gangetic plain exhibit high aerosol loading in comparison with the Himalayan foothills and central Himalayas of Nepal. We found not only the higher aerosol loading in atmosphere over site Lumbini but also higher periodicity. Likewise, we also found Pokhara as highly polluted as Lumbini. The investigation of data records over the site Kathmandu has shown increment in aerosol loading in the year 2016 compared with previous years.

Spatial orientation of galaxies in supercluster S[227+006+0078]
Authors: Malla Janak Ratna , Saurer Walter , Aryal Binil
Published: December 2019

We present a study of spin vector orientation of 1218 SDSS (Sloan Digital Sky Survey) galaxies in Supercluster S [227+006+0078] having redshift 0.07 to 0.09. The database of these galaxies is taken from SDSS (Sloan Digital Sky Survey) 7th and 9th data release. We have converted two dimensional data to three dimensional by Godlowskian Transformation using position angle-inclination angle method. We intend to find non-random effects in the spatial orientation of galaxies in the Supercluster.  No preferred alignment of angular momentum vectors is noticed, supporting Hierarchy model of galaxy formation.

Conventional to slow muon microscopy – a review
Authors: Pant Amba Datt
Published: December 2019

Because of special characteristics (fully spin polarized and asymmetric decay to positron), muon acts as sensitive probe to study the local electronic and dynamics of materials. The muon of energy MeV or high, conventional muon, are used to study bulk properties of the materials. For the study of nanoscience, slow muon (20 eV - 30 keV) muon with low energy spread are essential that leads to development of slow muon microscopy. Introduction to muon microscopy, application of conventional muons and need of slow muon beam along with future prospects are briefly discussed.

Published: December 2019

The compositional dependence of thermo-physical properties of Si-Ti liquid alloy has been reassessed using different modeling equations at temperatures 2000 K, 2400 K and 2473 K. The thermodynamic and structural properties of the system have been computed in the frame work of quasi-lattice test. The extent of surface segregation and surface tension of the liquid mixture have been computed using Butler’s equations at afore mentioned temperatures. The results so obtained have been compared with the available literature database. Theoretical investigations shows that the compound forming tendency of the system gradually decreases at elevated temperatures and hence it shows ideal behaviours, as expected.

TVET Approaches: A Diagnosis through the Lens of Human Capital, Right Based and Capability Approach
Authors: Thapa Binayak Krishna , Singh Aishwarya Rani
Published: December 2019

The key approaches utilised for the understanding and implementation of a Technical and Vocational Education and Training (TVET) are primarily human capital and human rights approaches. While human capital approach advocates enhanced skills for the productivity, human rights approach systematically demands distributed enhancement of skills through short- or long-term trainings for all. The former approach connotes economic growth through better employment and income opportunity, whereas the latter situates itself for distributive opportunity, social inclusion and social justice. Both approaches target increasing employment and enhancing chances for better livelihood and well-being. These two approaches, however, are not the ultimate and only approaches for understanding the technical and vocational education and training. The major limitations of these approaches are that they conceptualize employment, income, better opportunity and even distribution to be ends or goals, while in this paper, the authors argue that the mentioned concepts are just means to a general end that is human development. Given this context, this paper offers an alternative lens to look at technical and vocational education and training. This alternative lens is arguably capability approach. The capability lens potentially explains how skill enhancement improves the ‘being’ and ‘doing’ of a person who engages in taking training and how the trained person can implement the learned skills to improve his/her well-being. In this regard, this approach helps understand how TVET can directly be linked with human development. This paper finally argues that TVET is also a tool for human development, albeit it is primarily, still concerned with productivity, employment and better incomes.
Cosmological Orientation in Promoting the Enrollment in Short-Term Mobile Skill-Trainings: A Narrative Inquiry on Women's Lives in Nepal
Authors: Adhikari Devendra
Published: December 2019

The Government of Nepal has prioritized the need of mobile skill-training program for imparting the skill-training opportunities to the potential beneficiaries in their own settlement both in urban and rural areas. It is different from the centrally based training program as it is conducted by setting temporary training venues in particular settlement where the training participants are residing in the majority. This paper describes how adult women exhibit readiness to participate in the short-term mobile skill-training program in Nepal. The paper is based on a qualitative study with an interpretative paradigm following the narrative inquiry approach. The four participants were selected based on their experiences of receiving the training through mobile skill training program and currently employed in the trained trades. The interpretations of their life stories reveals that women in Nepal choose to enroll in the short-term mobile skill-training program as they believe it to be a gateway for them to get social recognition. Likewise, they prefer closer training venue and short duration training program due to their responsibilities towards their family. The findings of this research are useful in framing appropriate plans and policies for conducting short-term vocational training programs in mobile venues for bringing socio-economic changes in women's lives by respecting their family value system.
