In this paper, the radial deformation and the corresponding stresses in a homogeneous an infinite cylinder for an orthotropic material has been investigated. A numerical technique is proposed to obtain the solution of the transient coupled thermoelasticity in an infinite cylinder with its base suddenly subject to a heat flux of a decayed exponential function of time. The system of fundamental equations is solved by using an implicit finite-difference method. The present method is a second-order accurate in time and space and unconditionally stable. A numerical method is used to calculate the temperature, displacement and the components of stresses with time t, rotation, magnetic field and through the radial of the an infinite cylinder. The results indicate that the effect of magnetic field and rotation on temperature, stresses and displacement is very pronounced. Comparison is made with the results predicted by the theory of thermoelasticity in the absence of rotation and magnetic field.

The sheep breeding industry forms a substantial proportion of the agriculture sector in the Republic of Kazakhstan. Ensuring its sustainable functioning should be implemented in a number of national documents, which can be considered as the basis for increasing the level of national food security. This can be achieved also by conducting research that will reduce the incidence of disease in livestock. The novelty of the study is determined by the fact that in the extension study of autopsy of sheep affected by diseases, an analysis of factors that increase the incidence of melaphagosis was carried out. The main effects of classical and innovative drugs that reduce the melophagosis incidence are presented. The analysis of the seasonal level of morbidity and the age composition of sheep herds was carried out. It has been determined that the treatment and prevention of melophagosis can be performed on the basis of a combination of 2 and 5 drugs, both chemically active and biogenic. The practical significance of the study suggests the possibility of a considerable reduction in the level of parasitic invasions in the steppe conditions of Kazakhstan and stabilisation of the produced level of sheep breeding.

Abstract\nThis research aims at assessing the perceptions of teachers and students using songs in teaching and learning foreign language. This study used qualitative methods for collecting data. The instruments include class observation for eight lessons (8 weeks) and open-ended structure format interview session to assess the implementation of songs in foreign language classes. All foreign language teachers in one school in Malaysia were interviewed. However, focus groups interview was conducted among school students. This research involved thirty (30) male and female Japanese language students and three foreign language teachers. Purposive sampling method was chosen in this research. The findings presented would seem to indicate that implementation of songs in teaching and learning foreign language has a variety of uses at different levels of learning and teaching. Further, the results revealed that teachers have the potential to enhance students’ understanding of foreign language in different ways.

Code-switching is a linguistic phenomenon that occurs in multilingual communities around the globe. This study aims to uncover engineering students’ perceptions about ESL Teachers’ code switching from English to Sindhi language in a traditional classroom setting. One hundred fifty (150) participants ranging from different engineering departments participated in this research study. A questionnaire comprising 10 items employing 5 point Likert scale was employed to quantify the perceptions of engineering students about teachers’ code switching. Questionnaire was partially adopted from a study of Muhammad Fareed Dar et. al, (2016) on ESL teachers code switching. Data were analyzed quantitatively using Statistical Package for Social Sciences (SPSS, 23.0) for percentages against each variable. Findings revealed that i) teachers’ code switching helped engineering students understanding lecture easily, ii) it assisted students understanding the task better, iii) it generated confidence among students for speaking and participation in other classroom activities, iv) developed motivation for working hard more in engineering subjects, v) and facilitated students process of learning. Thus, findings endorse that teachers code switching plays paramount role in promoting effective classroom teaching and learning.

Demotivation is a novel addition in Second language research these days. This research endeavors to explore demotivating factors for male and female college students having English as a foreign language (EFL) course. The sample size for this study were 200 first and second year college students. 100 male and 100 female students equally participated in this study. Random sampling method was employed as a research technique. The data analysis was done quantitatively using Statistical Package for Social Sciences (23.0) version. The research findings exhibited that 1st and 2nd year college students recorded significant differences in terms of class material and lack of interest. However, they showed low scores for the factors ‘experiences of failure’, ‘class environment’ and ‘class materials’ as demotivating factors. The insights of this study provide a platform for novice researchers to explore further research in second language learning.

Composite copper-ceria adsorbent prepared by different method such as sol-gel and co-precipitation method and their performances for cadmium removal from aqueous solution. Cadmium pollutant in the intake water is a serious matter affecting health of people of developing countries such as India, Nepal, Bhutan, Bangladesh and others and requirements cost efficient solutions. Prepared adsorbent were characterized by particle size, BET surface area, X-ray Diffraction, Fourier transform infrared spectroscopy, Tunneling Electron Microscopy and X-ray photoelectron spectroscopy analysis. TEM showed that the different technique prepared such as sol-gel and co-precipitation abundance of approximately hexagonal shaped copper oxide ceria with size ranging from 15 to 20nm and having an average size distribution of 15.45 nm for sol-gel, and 16.79 nm for co-precipitation respectively. Synthesized adsorbent by sol gel method show the better cadmium removal than co-precipitation methods. The kinetics of cadmium adsorption investigated by changing cadmium concentration and amount of adsorbent for a phase of one hour exposed second order adsorption kinetics. The prepared copper ceria composite adsorbents have possible use for cadmium removal from aqueous solution well below the permissible limit.

Cotton (Gossypium hirsutum L.) is famous as “White Gold” due to its high quality fiber. Boron (B) is one of essential micronutrients that are involved directly or indirectly in many plant processes. Cotton growth, yield and quality are intensely influenced with B application. A 2-years field based study was conducted to explore the impact of foliar applied B (0.0, 0.5, 1.0, 1.5, 2.0 and 2.5 kg ha-1) on productivity and quality of cotton cultivars (FH-113, MNH-786 and CIM-496). Outcomes of the experimentation reflected that application of various levels of B significantly influences the growth and quality attributes of cotton cultivars. Crop growth rate, plant height, sympodial branches per plant, seed cotton weight per boll and seed cotton yield were recorded maximum by application of B at 1.5 kg ha-1 during both growing seasons. Quality parameters including fiber strength and fineness were also improved by foliar application at 1.5 kg ha-1. Among the cotton cultivars, FH-113 performed better regarding productivity, yield and quality of produce during both of the years of cultivation. Maximum field benefits or net returns were obtained by foliar applied B at 1.5 kg ha-1 in cultivar FH-113 during both experimental years. Findings of current experimentation indicated that foliar application of B at 1.5 kg ha-1 is considered economical to produce good quality of fiber with enhanced seed cotton yield.
