This work aim at investigate the influence of grass-cutter hair fiber (GHF) as reinforcement in polypropylene (PP) composites. The mechanical and water absorption behaviour of the fabricated GHF/PP composites were investigated. From the result, it was observed that at low weight fraction of GHF after treatment, both the mechanical and wear properties were enhanced, which may be attributed to the removal of waxy materials from the fiber surfaces and the addition of oxygenated functional group at the surface and edges of the fibers. While the water absorption capacity of the composites was enhanced due to the presence of hierarchical micro-pores in the composites. Hence, the composites can be used as light-weight engineering materials for automobile applications.

The importance of office facilities and workplace environment in the university system cannot be overemphasized because office facilities help in facilitating work schedules and increase staff's efficiency and productivity. Unfortunately, in many universities in the developing countries such as Nigeria, there are in-adequate facilities in the staff offices, and such has resulted in low productivity and has impacted negatively in universities' global ranking. The study assessed the facilities provided in the staff offices at the federal university of technology Akure Nigeria and examined the essential facilities that influence staff productivity. A total of 204 questionnaires were administered to both the academic and non-academic staff members drawn from the eight (8) academic schools that are in the university. 184 of the administered questionnaires were retrieved from the respondents representing 90.2% and therefore served as the basis for the analysis. A descriptive method of analysis was used to analyze the data. The study revealed that the conditions of fire prevention facilities such as fire extinguisher installed for workers are not functional; the same applies to the toilet facilities. Also, the further revealed that the staffs are very dissatisfied with the condition of conveniences and the state of the sofa in the offices. Finally, the study revealed that the most relevant facilities that influence staff productivity are water, electricity, and Wi-Fi. The study, therefore, recommends that the universities should make adequate provision for water, toilet, electricity, sofa, and fire extinguishers in the staff offices as these have the potential of motivating workers for greater commitment and higher productivity.

Emerging financial crises adversely affect the activities of banking institutions, which requires additional measures of the bank aimed at allocating resources with a minimum level of risk. Developed at the legislative level mechanism of interaction between credit bureaus and bank institutions will help to avoid losses and reduce the risk of damages in the implementation of credit operations. The study proposes to resolve some issues of improving the legislative and regulatory framework on the interaction of the bank lending segment and credit bureaus. The research results can be taken into account when making changes and additions to the current legislative framework. Banking institutions need to interact with credit bureaus, which specialize in collecting and storing information about borrowers. But there are problematic aspects observed in the functioning of the credit bureaus in the Russian Federation, which are analyzed in the article. The theme direction of the study is relevant, since when issuing credit funds a banking institution should minimize the risk of default.

Assuming that the surfaces of the truncated conical plates are transversely rough and considering the porous structure based on the Kozeny-Carman model, in the transverse magnetic field, the issue of the squeeze film between electrically conductive rough porous surfaces with electrically conductive lubricant is analyzed. The roughness of the surface of the bearing is dependent on a stochastic random variable with non-zero mean, variance and skewedness. After stochastically averaging the equation of Reynolds with regard to the parameter of random roughness, the pressure distribution, which in turn leads to the load carrying capacity, is solved with suitable boundary conditions. The analyses are displayed in both graphic and tabular form. It is known that the bearing roughness is transversely rough in general. Nonetheless, in the case of negative skewed roughness, the condition can be restored to some level by choosing the conductivities of the plate, if there is a negative variance. It is also found that even when there is no flow the magnetic field bearing can sustain a load.

The paper describes a method for solving the procurement optimization problem based on inverse calculations. The method involves solving the unconstrained optimization problem and adjusting the obtained values of arguments subject to the constraint. Compared to conventional nonlinear optimization methods, the proposed method is easier to implement with computer software, since it does not require any determination of additional variables and multiple solutions to an unconstrained optimization problem. A solution to a two-constraint problem using inverse calculations has been considered. In this case, the optimization problem is transformed into a single-constraint problem. Therefore, when constructing a system of equations for determining increments of arguments, the transformed form of the objective function and the constraint are taken into account. This paper discusses a solution to a procurement portfolio development problem for a confectionery company with a limited budget and a target value of contribution margin. The obtained solution was compared with the solution produced by the mathematical software package and the penalty method. The result of this comparison is presented in the paper. The proposed algorithm can be used in systems intended to support the procurement decision making process. The algorithm can also be used to solve quadratic programming problems of the considered form in other fields of research.

At one of the famous Tanzanian ferries - Kigamboni ferry terminal, it is common to find a long queue of people at the ticketing window and the entrance waiting for tickets to get into a lounge, respectively. At the tickets' window,one of the main identified problems is difficultness in picking tickets and time wasted during the printing process. Similarly, at the entrance, it takes an average of 12 seconds to scan a ticket due to systems' insensitivity. This study thus introduces a new system that would probably drastically reduce the time spent on two occasions. The system employs laser technology and non-paper-based tickets to save time by simplifying to processtickets, which will also increase the sensitivity of the system for saving time. The impacts of the proposed system will be realisedforthe entire communities by saving their time, government for effective revenue collection as well as a clean and safe environment by getting rid of paper-based tickets.

Trade openness is commonly viewed as one of the engines of economic growth. Hence, it is not surprising that several countries have taken measures to ensure that their industrial and trade policies permit some form of trade openness. This study analyses the relationship between trade openness and economic growth, highlighting some of the controversies on the effects of trade openness. From the existing literature, it is evident that the effects of trade openness are not always positive and significant, hence a closer investigation of the relationship between trade openness and economic growth is vital. Based on the findings, this paper recommends that policy makes must first address the enabling factors to ensure significant positive benefits from trade openness. This implies that countries must prioritise the aligning of their trade and industrial policies with trade facilitation, financial development, industrialisation, technological advancement and infrastructural development.

This research is intended to descriptively analyze person-organization fit, job satisfaction, and employee turnover intention. Besides, this research aims to analyze the influence of person-organization fit and job satisfaction on employee turnover intention, both simultaneously and partially. The type of this research is descriptive and verification research. The population in this research consists of employees from Bank SyariahBukopin, Bank BNI Syariah, and Bank JabarBantenSyariah. Sampling technique used in this research is non-probability sampling using a saturated sample technique. This research uses multiple regression employing more than one independent variable, namely person-organization fit (X1) and job satisfaction (X2). While the dependent variable is the turnover intention (Y). The results of this research show that turnover intention is significantly and simultaneously influenced by person-organization fit and job satisfaction variables of 37.50%. While the rest 62.50% is influenced by other variables outside this research. They are possibly organizational commitment, employee engagement, social support, change management, leadership, organizational behavior, and others. It is thus implied that there are many other potential variables which may affect employee turnover intention. Partially, the results of this research show that the person-organization fit does not affect turnover intention. However, job satisfaction affects turnover intention quite significantly. Thus, the better the job satisfaction is, the higher the turnover intention becomes.

Waiting inside the airport for the next flight (i.e., transfer) might be very lengthy and boring. Thus, many passengers have opted to get out of the airport to participate in transit tours, which are mini all-inclusive packages of the necessary tour components. However, due to the novelty of the operation, the existing literature has not covered this issue yet. The purpose of this study, therefore, was to develop a theoretical framework to explain the transit tour concept. From there, the four cases of Seoul Incheon Airport, Singapore Changi Airport, Tokyo Narita Airport and Beijing Capital Airport were investigated to understand participants' perceptions of the transit tours. Outcomes of the analysis of reviews posted on tripadvisor.com suggested that the tours were perceived differently among airports. Based on these findings, practical implications for tour providers, airports and tourism administration organizations were discussed.
