Article: An Analysis of the Determinants of Investment Attractiveness for FDI Inflows into the Russian Federation
Davydova Iana
Vol 3, Issue 7 ; July 2020
North American Academic Research, 3(6) 234-259, 2020, https://doi.org/10.5281/zenodo.3966523
Abstract: After the annexation of the Crimean Peninsula in March 2014, the US, the countries of the EU, and their partner countries imposed economic sanctions against the Russian Federation. Shortly thereafter President Putin introduced retaliatory sanctions. Along with the sanctions, came the oil price downturn that caused the outflow of Foreign Direct Investments (FDI). Thus, defining and studying the primary factors of investment attractiveness for the FDI inflow is the problem of the current importance. The following paper using theoretical and empirical methods is focusing on studying the main economic determinants of investment attractiveness for FDI inflows into the Russian Federation. The primary objective of this paper is to determine economic factors influencing the FDI inflows into Russia, focusing on the non-favorable economic and geopolitical conditions. Overall, it answers the question “What are the main current determinants of investment attractiveness for the foreign direct investments into the Russian economy?”. The analysis of the structural dynamics of FDI inflows into the Russian Federation showed the main investor countries are offshore territories, which is not favouring the further development. Overall, the investment environment in Russia cannot be called generally attractive for the FDI due to the high level of corruption, unstable currency, and lack of developed infrastructure. The empirical part applies regression analysis of controlled variables. A correlation matrix shows that all the used variables are related correctly. Further, the author found that throughout the given time-frame (2010-2018) among all the economic determinants the most impact on the FDI inflows into the Russian Federation had GDP and the level of trade openness. However, against all expectations, economic sanctions did not have a significant impact on FDI inflows.

Sanjoy Kumer Debsharma, Popy Rani Roy , Rouson Ara Begum , Palash Kumar Kundu , A K M Shalahuddin , Khandakar Md. Iftekharuddaula
Vol 3, Issue 7 ; July 2020
North American Academic Research, 3(7) 223-233,July 2020, https://doi.org/10.5281/zenodo.3960983
Abstract: Forty-eight rice genotypes of inbred and hybrid rice varieties developed or registered by different organizations were evaluated for their stability for grain yield through regression coefficient and deviation from regression analysis. The experiment was laid out in a randomized complete block design with three replications at seven locations of Bangladesh. Highly significant mean sum of squares due to genotype and environment and pooled deviation indicated sufficient variability among the genotypes and environments for yield and revealed the importance of a non-linear component accounting for the total genotype-environment interaction. Khulna (E3) was found as most favorable location because of showing highest environmental mean yield and environmental index. The stability parameters for grain yield revealed wider adaptability of the genotypes V5 (BRRI dhan30), V13 (BRRI dhan49), V29 (Binadhan-17), V33 (Mukti-1), V34 (Agro dhan-12), V35 (Bayer hybrid dhan-4) and V41 (BADC hybrid dhan-6). The genotypes V32 (BRRI hybrid dhan6), V1 (BR10), V40 (BADC hybrid dhan2), V15 (BRRI dhan52), V7 (BRRI dhan32), V21 (BRRI dhan72), V20 (BRRI dhan71), V30 (Binadhan-7), V6 (BRRI dhan31), V31 (BRRI hybrid dhan4), V26 (Binadhan-11), V19 (BRRI dhan66), V48 (Bindhan-4), V24 (BU dhan-1), V22 (BRRI dhan73), V38 (Hera-16), V44 (BRRI dhan44), V36 (Bayer hybrid dhan-6), V2 (BR22), V46 (BR11) and V43 (BRRI dhan75) showed insignificant regression coefficient (bi) values and higher mean yield than the grand mean and positive phenotypic index (Pi) indicating them to be suitable for poor environment.

Article: Afghan Public University Teachers’ Perceptions of Teaching through Technology in the Classroom
Abdul Saboor Zaheeb, Abdul Samad Roshan, Baseer Ahmad Yaad
Vol 3, Issue 7 ; July 2020
North American Academic Research, 3(7) 180-192, July 2020, https://doi.org/10.5281/zenodo.3945566
Abstract: This study aims to investigate Afghan public university teachers’ perceptions of technology use in the classroom. Furthermore, the purpose of this research is to explore teachers’ perceptions of technology use in the classroom for learning and teaching, technical support from, and online classes. The quantitative data, out of 55 respondents from different universities of Afghanistan, were collected and descriptively analyzed through using Statistical Package for Social Science (SPSS) Version 26. The results of this study revealed that Afghan public university teachers’ perceptions of using technology in the classroom were moderately positive. Notably, their perceptions were highly positive in learning and teaching through technology in the class. It is indicated that teaching through technology could affect both teachers’ and students’ academic performance and enhances the collaborative skills of them. Additionally, their perceptions toward online classes and technical support were moderately positive, and they believe that they are very interested in teaching online courses, but the technical support from the faculty and university has delayed the proper usage of technology in the classroom. Besides, it is revealed that university and faculty do not provide them the technical support for enhancing technology use in the classroom, for example, the instructional workshops, seminars, and hardware and software. Based on the findings, it is suggested to the Ministry of Higher Education (MOHE) in Afghanistan to encourage the culture of electronic teaching and learning and provide them enough technical support and workshops on technology use in the classroom.

Article: High biodegradability of SF/Eco-friendly degumming for biomedical applications
Sourav Kumar Das, Rafique Ulla Fayazi , Huang wei
Vol 3, Issue 7 ; July 2020
North American Academic Research, 3(7) 159-172,July 2020, https://doi.org/10.5281/zenodo.3945539
Abstract: Degumming is the process of removing the sericin, a sticky substance produced by the silkworm which holds together the silk strands. This is also regarded as scouring thread. Removing the gum enhances the silk's lust, colour, hand and texture. When the gum is extracted, as much as one third of the weight can be lost. In this study, we will discuss the advanced methods used in silk degumming and high biodegradability for biomedical applications. Higher amount of degumming loss was observed for both white and brick red eri silk cocoons with more sodium carbonate concentration and boiling duration.Single fibre tenacity declines with increased concentration of sodium carbonate and boiling time. Degumming of silk requires the cleavage of sericin peptide attachments, either by hydrolytic or enzymatic processes, and eventual sericin elimination from the silk fibroin.Sericin hydrolysis may be conducted under normal, alkaline or acidic conditions to give four fractions, each of which has different properties. The most common form of degumming is boiling-off in alkaline soap solution. There are several qualitative approaches for determining the degree of degumming; however, quantitative methods are yet to be established. Degumming may be performed in manually or mechanically controlled machines on thread or cloth. In this analysis we have discussed several modern, eco-friendly methods of silk degumming

Vol 3, Issue 7 ; July 2020
North American Academic Research, 3(7) 98-109, July 2020, https://doi.org/10.5281/zenodo.3937912
Abstract: The research aimed to investigate the effect of leaf clipping on growth, flower production, and yield of mungbean (Vigna radiata (L.) Wikzek). A field experiment was carried out in four mungbean genotypes viz. BINA moog-5, Mutant E4I-915, Mutant N2M-402, and BINA moog-7. The leaf clipping levels of 0%, 33%, and 66% imposed at the vegetative stages (40 days after sowing) in all four genotypes. The morphological, reproductive, and yield attributes estimated in the study had shown substantial differences for the leaf clipping treatments in all four mungbean genotypes. Leaf area, leaf dry weight, stem dry weight, total dry matter, plant height, number of branches per plant, number of open flowers/plant, number of pods/plant, pod length, number of seed/pod, 100-seed weight, single pod weight, straw yield, seed yield, and harvest index varied significantly in four mungbean genotypes. Almost all the studied parameters showed statistically identical performance at 0% and 33% leaf clipping level of the mungbean genotypes, and the least performance recorded at 66% leaf clipping. Therefore, mungbean genotypes appeared to compensate for their yield attributes up to 33% leaf clipping at 40 days after sowing. BINA moog-5 showed the preeminent tolerance against the leaf clipping among the genotypes under study.

Abstract: The research aim is to analyze Entrepreneurial Self-efficacy, Innovative Behavior, Formal Credit Access, and its impact on Micro and Small Enterprises' (MSEs) success. Determining variables that support business success is important because MSEs are the backbones of a country's economic The challenge for the government is that MSEs fail in the first three years. High Entrepreneurial Self-efficacy fosters an attitude to find opportunities, and able to withstand challenges. Innovative behavior leads MSEs to find, try, and implement new ideas. Capital needs can be met by having formal credit access. The survey was conducted on a sample determined through purposive sampling. Data processing uses multiple linear regression. The results showed that Entrepreneurial Self-efficacy, Innovative Behavior, and Formal Credit Access simultaneously have a positive impact on the MSEs' success. Entrepreneurial Selfefficacy and Formal Credit Access partially have an impact on the MSEs' success, while Innovative Behavior has no partial impact on the MSEs'success.

North American Academic Research, 3(7) 85-97, July 2020, https://doi.org/10.5281/zenodo.3936245
Abstract: This paper described that molding is one of the important metals forming process in manufacturing components for various applications in industry. Casting of any size and shape can be made accurately. Automation in this field helps to improve the foundry environment and accuracy of the cast parts. Efficiency of molding is affected by various parameters like permeability, collapsibility, adhesiveness etc. So it is a must to avoid defects in casting. The defects occur in sand castings post a great problem in foundry. On account of defects more than 10% castings are rejected. Even though skilled labor is employed for ramming operation, the packing of molding sand will not be even throughout the molding box. So we have selected the idea of fabricating pneumatic rammer. This rammer is operated pneumatically. By using this rammer molding sand will be packed evenly throughout the box.

North American Academic Research, 3(7) 57-72, July 2020, https://doi.org/10.5281/zenodo.3930252
Abstract: The purpose of this study is to examine the impact of global competitiveness index (GCI) on the dimensions of logistics performance (LP) model for Asia countries. Panel data on 37 Asian countries over 2007-2018 were regressed under hierarchical regression analyses. Core variable GCI along with two control variables has been used in the study. Findings generated from the regression demonstrate that six dimensions of logistics performance of Asian economies could be improved by implementing global competitiveness index. Six individual models on efficiency of customs clearance process, transport related infrastructure, competitive price shipments, quality of logistics services, frequency of shipments, and tracing and tracking are statistically significant and execute more than 65% variations while the impact on competitive price shipments is mild. So, the model significance & statistical change in R2 & adjusted R2 signifies the contribution and the importance of GCI in context of policy implementation to improve Asian logistics performance taking GCI as the catalyst for LP.

Vol 3, Issue 7 ; July 2020
North American Academic Research, 3(7) 33-56, July 2020, https://doi.org/10.5281/zenodo.3930242
Abstract: This study examines the hierarchical level of competitiveness in Asian countries using 12 global competitive development indicators. We applied multivariate analysis- Hierarchical Cluster Analysis (HCA) and Principal Component Analysis (PCA) to distinguish the clusters combination in 33 Asian economies. The research has identified two principal components responsible for 78% variations of the indicators in the data sets. And the countries have been classified into four clusters- A, B, C and D with some sub-clusters. The result proves that economies like Singapore, Japan, S. Korea, Qatar, Malaysia, Israel and UAE are on the top of hierarchy where Cyprus and Bahrain are in the 2nd cluster, while the rest are in 3rd & fourth cluster. The analysis showed infrastructure (INFRT 0.950), business sophistication (BS 0.926), & goods market efficiency (GME 0.920) have the highest impact on Asian development while the other are also contributing. Most of the development indicators kept very close connection to PC1 while only two- macroeconomic environment (MEE) and market size (MS) are close to PC2. So, this research mainly emphasizes on the hierarchical classification of the countries and sort out the main component influencing the development trend in Asia. Furthermore, it will help policy makers and investors to emphasize on the facts those have direct influence on sustainable Asian development policy as well.

Abstract: Type 2 diabetes mellitus (DM) has become a public health problem that seriously influences patients' quality of life. Identification of the level of knowledge related to diabetes among the general public is essential in strategies for prevention of diabetes mellitus. This study aims to assess the baseline levels of knowledge and its relation with glycated hemoglobin (HbA1c) level in diabetic patients in Taiz. The study was conducted on forty individuals with type2 diabetes of both sexes and used a questionnaire for data collection from Yemeni population than find the relationship between knowledge and HbA1c, blood glucose (BG) and Body Mass Index (BMI). Results showed significant differences (P < 0.05) in the knowledge, HbA1c, BG, and BMI between the samples studied, where demonstrated that 5% of samples was knowledge above 68 % and had a lower HbA1c level less than 6, also shown that 40% of the samples was knowledge 60 % with an average of HbA1c level 8%. In comparison, 32.5% of samples were knowledge less than 50% and had a high average HbA1c level 11%, also found there is a relationship between knowledge and BG, BMI, even the knowledge on the disease for males (52.81%) better than females (47.19%). Type2 diabetic patients have a decrease in knowledge, and this affects levels of HbA1c and BG, even who has good and moderate knowledge, not reflected on their attitudes towards HbA1c and BG.

Abstract: Land surface temperature (LST) is an essential parameter for the urban thermal environment and global climate change studies. The significant of LST is being acknowledged gradually and indicates that Vegetation cover has an immediate impact of Land surface temperature (LST). The main objective of this study is, retrieval of Land Surface Temperature (LST) and its relationship with Normalized difference vegetation index (NDVI) by using the different satellite imageries including Landsat 5 (TM); Landsat 7 (ETM+); and Landsat 8 (OLI) for 1998, 2003, 2008, 2013 and 2018 in Lahore and Peshawar city (Pakistan). A combined technique of GIS and Remote Sensing has been applied for retrieval of LST and NDVI, and further, their relationship was checked by using linear correlation regression. Results indicate a rising trend of LST and decreasing trend of NDVI in Lahore, while the pattern of LST in Peshawar shows declining trend and NDVI shows an increasing trend. R 2 Coefficient value between LST and NDVI is very significant. The areas with low vegetation cover have a high temperature as compared to the areas which contain vegetation cover
