Abstract: The fitness of animal has an enormous influence on its reproductive capability, nowadays feeding of microelements is practiced in many feed formulations because micro-nutrient possesses strong influence on animal’s reproductive ability. The male generative zone produces spermatozoa which needs a little number of free radicals for the maturation as well as for smooth fertilization. Whereas the raised level of these free radicals disturbs the entire process of sperm formation and also lead to infertility. The Selenium is a micro nutrient which naturally possess some enzymes and selenoproteins which diminish manufacture of unnecessary free radicals by acting as an antioxidant. Subsequently, it protects male gamete from destruction triggered by oxidative stress. Selenium also assistance in maintenance of semen quality by declining construction of atypical spermatozoa. Additionally, some studies have revealed that it possesses striking influence on both gross and histological characteristics of male reproductive organ, feeding this mineral improved circumference, size, the mass of the testis and speed up sperm construction by means of having a solid effect on seminiferous tubules histology. Hence, selenium shortage can cause infertility and further reproductive syndromes. Keywords: Male reproduction, selenium, Oxidative stress, Antioxidant. |

Abstract: Learning programming is hard for novice students. Complicated syntax and semantic of programming languages and lack of previous knowledge are the contributing factors behind the hardness of programming. Natural programming language allows to program in a natural language and thereby ease the programming. In this paper, it is ascertained whether natural programming language is fruitful in learning the elementary programming concepts and supportive in preparing students for introductory programming courses. The discussion included in this paper can be used to design supportive programming languages and formulating effective courses and learning material to ameliorate performance of students’ in learning of introductory programming environments. Keywords: Introductory programming courses, natural language programming, CS0, failure and dropout rates. |
Abstract: An Empirical Analysis of a Process Industry to Explore the Accident Causation Factors: A Case Study of a Textile Mill in Pakistan

Abstract: Industrial revolutions not only improved the general lifestyle of individuals but also brought an increase in the diversity of the manufactured goods. This diversification involved use of advanced technology and complex methods that entailed dangerous conditions. According to international labor organization, occupational accidents cause death of more than two million individuals each year in different industries. Process industries are complex in nature and tend to lead to more accidents. In Pakistan among the process industries, textile mills are the most accident prone industries in recent times. Therefore, an empirical analysis of a textile process industry has been done using structural equation modelling to examine the interactions between the contributory factors of accidents. Results revealed that unsafe acts are a major contributor to human error, equipment error and unsafe environment that in turn lead to the calamities and disasters that can be avoided with proper safety measures in place. Keywords: Empirical analysis, Accident causation, Process industries, Structural equation modelling, Industrial Safety. Download Full Article |
