The performance of software development teams is an important topic in the field of IT projects. Previous research has found that the factors such as communication, cohesion, mutual support, coordination of expertise, trust and value diversity affect performance of team members in software development projects. However, the findings of existing studies cannot be directly applied to the Sri Lankan context due to cultural and behavioural differences of people in Sri Lanka compared to western countries. Thus, the aim of this study was to investigate the factors influencing the team performance in software development projects in Sri Lankan IT companies, as Sri Lanka is one of the emerging countries engaged in software development projects. Thus, the study examined the factors influencing effective and efficient team performance in software development projects. This study mainly considered a sample of 186 IT professionals who work in large-scale IT companies in Sri Lanka, and the data was collected through an online questionnaire. Based on the results, the hypotheses were tested to identify the effect of each influencing factor on the performance of software project teams. It was found that communication, cohesion, trust, value diversity and coordination of expertise have significant positive effect on team performance. The findings of this study would be useful for managers, team leads and project managers to enhance the performance of software development teams.

This paper investigates the determinants of Sudan balance of payments using annual data on balance of payments (BOP), foreign debt (ED), exchange rate (EX), inflation (INF), gross domestic product (GDP) during the period (1980 - 2016). The paper elaborates the problem regarding the impact of foreign debt on the balance of payments. The paper built on the fundamental assumption that the foreign debt linked to a positive relationship with the balance of payments by running VECM Approach. Results of the study indicate that there is a direct correlation between the balance of payments and foreign debt, and an inverse relationship between the balance of payments and all of the inflation, gross domestic product and exchange rate during the forementioned period. The paper recommends that Sudan should not totally dependes on foreign aid in solving its economic problems which entails to transfer big amount of the national product to meet the commitments towards those foreign countries, the need for coordination between macroeconomic policies and domestic economic policies in order to increase output domestic product, economic policies are functioning to reduce the ratio of foreign debt and the reduction of inflation and bring about stability in the exchange rate which leads to improving the balance of payments to be adopted by Sudan.

This study is carried on to investigate the effect of (UV) on the estimate of vitamin D production and the correlation ratio of vitamin D and its impact on the increase of blood glucose finally to prove the relationship via biochemical analysis of Vitamin D and glucose level. 90 adult rats were randomly divided into three groups. G1 (-ve control): This group contains 30 rats that were not exposed to the ultraviolet. Rats were eating daily/4 months. G2 (+ve control): This group contains 30 rats that were not exposed to the ultraviolet. Rats were fasting 2 days and eat the third day frequently (4 months). G3: Test group: To examine the exposed to the ultraviolet for 10 second to simulate sunrise and another 10 second to simulate sunset (using prototype cage). This group contains 30 rats, which were fasting 2 days and eat the third day frequently (4 months). Weights were recorder every week. The blood samples were collected through retro- orbital venous plexus in the zero time, every month, and at the end of four months and the obtained sera were subjected to the Glucose and D3 tests. The results showed that the body weights were reducing significantly in G1 compared with G3 at all measured periods (P < 0.000). Whereas no significant differences between G3 and G2 in all weeks. The Glucose levels in G1 and G3 were raised significantly in (1st, 2nd, 3rd and 4th month) (P< 0 .035), (P< 0 .036), (P< 0.030) and (P< 0.023). Also blood level of Glucose was raised significantly between G3 and G2 in all periods (P< 0 .008), (P< 0 .009), (P< 0.002) and (P< 0.001). Moreover the blood levels of Vitamin D between G1 and G3 were raised significantly in all tested periods (P< 0 .001), (P< 0 .000), (P< 0.000) and (P< 0.003). Also Vitamin D was raised significant (P< 0.000) in G3 compared with G2. This study was proved that vitamin D level was affected by the exposure to ultraviolet that intern affect the glucose level. Also ultraviolet (UV) extend to preservation of glucose homeostasis by raising glucose level. Accordingly ultraviolet (UV) raising vitamin D should be considered since this may help reduce the risk of glucose disorders.

In this paper, we have described a whole new approach of rationalization of existing traffic control systems by means of Fuzzy logic based control system and Vision sensors based vehicle counting method. As Conventional traffic control systems are inefficient because they provide fixed time-delay though no vehicle is present in that lane. So it results in congestion of vehicles on the adjacent side. And it generates the Noise and Air pollution, which is undesirable and not favorable. In an Intelligent traffic control system (ITCS), vision sensors will measure the number of vehicles on arrival as well as on queue side, and fuzzy logic rule based system will provide the rational time-delay, which is dependent on vehicle density on both arrival and queue side. So it will give zero delays if no vehicle is present in that lane. So ITCS works with intelligence given by the Fuzzy logic system.

This research investigates the impact of remittances on financial development of Pakistan. Overseas remittances have positive and major relation with GDP of Pakistan at the same time as inflation and exchange rate has unconstructive effect on economic growth. The multiple regression investigation is used to identify the relationship between the dependent and independent variables. In this study, we considered economic growth as the dependent variable. For independent variables worker’s remittances, foreign direct investment, inflation, and exchange rate and agriculture growth.
