1. Using Application Software, Tools, and Equipment to Facilitate Engineering and Computer Classes Online


This paper aims to study the use of emerging technologies in online classes in undergraduate engineering and computer technology programs. The study especially aims to examine the specific technologies, software, apps, tools, and equipment that can be used to deliver lab-based classes in fully online mode in undergraduate Electrical Engineering, Electronic Engineering Technology, Cyber Security, and Information Technology programs. Based on extensive review of the existing literature, the available digital technologies such as e-learning platforms, application software, tools, and equipment were identified, synthesized, and presented. Currently available diversified online learning and communication platforms that can be adopted integrating different popular and widely used software, apps, and tools for effective online learning were discussed in this study. Various features, functions, and activities performed by students and instructors during fully online synchronous and asynchronous classes were identified, examined, and analyzed. This study would be beneficial for instructors, administrators, and e-learning facilitators in higher academic institutions while adopting e-learning platforms to deliver online classes in undergraduate engineering and computer technology programs.

2. Distribution Channels and Sales Performance in Nageria: A Case Study of Some Selected FMCGs in Ibadan


The broad objective is to examine the relationship between distribution channels against sales performance among selected FMCGs in Ibadan. The relationship between the dependent variable (sales performance) and the independent variables (distribution channel) was examined with inferential statistics. The respondent characteristic was ascertained using descriptive statistics. The study examined the reliability and validity of the questionnaire using pre-test with Cronbach's Alpha Value. The study concluded that there is positive and significant relationship between current distribution channel, distribution channel relationship, distribution channel component, distribution channel intermediary and sales performance among selected FMCGs in Ibadan. Further studies can be carried out to examine other factors and determinants of distribution channel and their impact on sale performance. This study examined FMCGs in Ibadan but other studies can be carry out to expand the sample and change the geographical scope of the study.

3. Does Work Environment, Supervision Affect Employee Productivity in Nigeria Banks?


Studies on how work environment and supervision, influence productivity have gained much attention in the oil sector, distributive trade sector, communication sector and the manufacturing sector but the reverse is the case in the Nigerian banking industry. This research work, therefore examines the impact of work environment and supervision on employee productivity in Nigerian with reference to the banking industry. The Nigerian banking industry was taken, as the case study with a sample of 517 employees drawn across the selected banks. A survey research design and systematic literature review were employed to achieve the study objectives. Thereafter, the researcher used Moos (1981) validated scale on work environment, Mowday, Steers and porter, (1979) validated commitment scale, Robinson, Kraatz and Rousseau, (1994) validated scale necessary modification to collect the required data from the respondents. The outcome of this research work indicates that office furniture, ventilation, light, Atheistic design/ structure, supervisor support, co-workers’ relations positively and significantly affect staff productivity and that the supervision style such as, Open communication, employees participation in organization, performance monitoring, creativity has great impact on bank employee productivity. The study, therefore, concluded that the Nigerian banks must pay attention and respond to the employees work environment and supervision as it have a significant effect and drive employee to perform their assigned job effectively and efficiently which will eventually lead to productivity.

Keywords: work environment, supervision, performance, Nigerian banks.

4. Impact of Foreign Direct Investment on Economic Growth of Bangladesh


There is a widespread belief of international organizations, planners, academicians, economists, researchers etc. that FDI has a robust optimistic influence on the economic growth. Purpose of study is to examine the impact of foreign direct investment on economic growth in Bangladesh. The study is prepared based on secondary source of data covering 1987 to 2020 where economic growth is taken as dependent variable and FDI, Market size, Exports, Imports, Inflation, Exchange rate are considered as independent variables. This study also utilized multiple regression analysis method for data analysis. The study results show that FDI and exchange rate have negative as well as significant impact on economic growth and concluded that one unit change in FDI and exchange rate will decrease economic growth of Bangladesh by 22.84 and 2.04 units respectively. However, export and market size have positive influence on economic growth of Bangladesh, where, one unit change of export and market size will increase economic growth of the country by 5.54 and 389.43 units respectively. On the other hand, study also found statistically insignificant positive association of inflation and import on economic growth of Bangladesh The negative impact of FDI on economic growth may be due to exporting goods without meeting the domestic demand for the goods, attaining monopoly power of foreign companies over local companies, excess competition between local and foreign companies, capital flight, repatriation of excessive profit to the parent country by foreign companies etc. Planners, economists, academicians, regulators, new researchers and related stakeholders shall get a significant perception about impact of FDI on economic growth and thereby enhance the economic growth. This study is carried out based on secondary data only. Secondary data is the main limitation of the study. Hence, there is a huge scope of further study using primary as well as secondary data.

Keywords: Impact, FDI, Economic Growth, Bangladesh.

5. Changes of Some Phenolic Compounds and Enzymes Activities on Leaf Gall on Ficus Glomerata Roxb. Caused by Pauropsylla Depressa Crawford


Pauropsylla depressa Crawford (Homoptera : Psyllidae) infests Ficus glomerata Roxb. and produces galls on its leaves, causing extensive damage to the foliage of the plant. The gall formation by Pauropsylla depressa causing the changes in the histomorphology, ecology and biochemical components of the host plant. Galls are pathologically developed cells, tissue and organs of plants, which have risen mostly by hypertrophy and hyperplasia (excessive cell division) usually under the influence of parasitic organism. Newly formed galls are green in colour, but as the gall grows due to the metaplasia induced by the feeding of instars in it, gall colour changes pale green. Later on, it develops brownish spots. After some time, greenish colour turns brown. During winter, mature gall turns pinkish due to the formation of some phenolic compounds. Mature gall contains a lacerated opening on the lower surface (ventral side) of the gall from which fifth instar nymph escapes out for moulting into imago.

Biochemical components such as phenols and enzymes analyzed in infected (galled) leaf showed either increase or decrease as compared to healthy (fresh) leaves. Phenolic compounds increase in gall tissue and during winter due to the presence of these, galls turn pinkish to trap heat. Enzymatic changes were recorded in healthy and gall tissues. Amylase and IAA oxidase and IAA (idols acidic acid) activities of these enzymes increased in mature gall tissues and decreased with the age of healthy leaf.

6. On Solving Special Types of Partial Differential Equation Using Collocation Method


This paper suggests the collocation method based on new Curtis trigonometric B-spline approach depending on the finite difference scheme, with the assistance of the weighted scheme for solving a one-dimensional non-linear Benjamin-Bona-Mahony-Burger (BBM-Burger) equation and Modified Equal Width (MEW) equation. The finite difference scheme is used to discretize the time derivative; whereas a quartic trigonometric B-spline is used as an interpolation function in the space dimension. The performance of this method is compared with the exact solution at different times and with a few other published numerical methods .The suggested method is a more efficient and effective tool which yields better results than other numerical methods
