Adders are the most vital part of any digital system. Providing an efficient adder design which satisfies the tradeoff between speed and space aides in increasing the performance of the system. parallel prefix adders are the ones widely used in digital design. This is primarily because of the flexibility in designing the adders. Brent kung adder is low power adder, as it uses minimum circuitry and also decrease the speed and memory to obtain the result. The 16-bit design is extended to 32-bit, implemented in the physical level.

In order to improve the English teaching effect, we adopt the information system as the assistance with the English teaching. By the online function and automatic management with the system software, teachers and students got more communication and achieved more effective results, especially on spoken English. The practice implies that it is feasible and effective to apply the information system to the English teaching.

Friction Stir Welding, a relatively new welding process, was developed in 1991 at The Welding Institute near Cambridge, England. In this process parts are mated together, rigidly fixtured, and joined in solid-state by forcing a rotating tool into the joint, and traversing that tool along the joint. This process creates weldments with properties comparable to the base metal and in most cases superior to traditional fusion welding techniques. During the Friction Stir Welding (FSW) process, the forging forces under the tool plastically deform the material, “stirring” the material around the tool pin and against the tool shoulder, thus joining the mated parts together. This process induces large shear forces in the plastically deforming material, raising the temperature of the material to approximately 80% of the melting temperature. The FSW process parameters such as tool rotational speed, welding speed, axial force, etc. play a major role in deciding the weld quality. In present investigation, the effect of processing parameters on mechanical properties of AA6082-O joints produced by friction stir welding was analyzed. Different welded specimens were produced by varying rotating speeds of the tool as 900 & 1200 rpm and by varying welding speeds as 50 & 63 mm/min. The FSW joints mechanical properties of the material such as yield strength, tensile strength and percentage of elongation were evaluated by means of tensile tests.

The purpose of this study is to determine the university student’s intention toward doing job or business. This study is based on primary data in which data collected from 150 students of different university of Lahore District, Pakistan. We use self administrated approach. The response rate is 86%. 64% of the students decide to do job and 33% decided to start their own business. 80% female are interested to do job, and 54% male willing for job because female are less risk taker rather than male. Female performance more to do a job rather than business because male to do business rather than job.

The national water policy of India is not concomitant with its land use pattern. The countries constituting the SAARC recognise trade and economic relationships among the member countries of Pakistan, Bangladesh, Srilanka, Nepal, Bhutan and Maldives but does not attempt at a comprehensive land and water resources policy for the region. But the rivers flowing in the SAARC region are not confined to national boundaries. In a similar manner no such policy exists among the member states of India. Population growth, unchecked urban migration against limited land and water resources has led to piecemeal and short term approaches to management rather than attempting at holistic global solutions in land and water sharing among the member states of India. For instance in Tamilnadu, water starved state, sharing of waters from the 45 rivers from neighbouring Kerala state has not been successful so far. With the result these rivers originating in Kerala flow waste to Arabian sea. One of the major drawbacks occurring in these exercises is the Tamilnadu has so far been concerned at its own interest in procuring water from Kerala rather than attempting to point out the benefits accruing to kerala which has no space to store the water. Research done in this regard reveal that benefits accruing to Kerala state are substantial in comparison with Tamilnadu.

The aim of this study was to establish the relationship between the Stature and Popliteal Height Sitting, PHS. 161 male occupational bus drivers were randomly selected for anthropometric characterization of Stature and PHS using standard measuring equipment. The data were analyzed using SPSS 16.0 and Design-Expert 6.0.8. Then regression model was used to estimate PHS. The model shows that there is a linear relationship between the Stature and PHS with coefficient of determination (R2) of 0.8258 (p < 0.0001). The model mitigates time required for gathering anthropometric data. Designers would find this as a huge working tool for adequate productions.

The objective of this study was to determine the internal and external quality characteristics of quail eggs and the effect of egg weight and body size on these traits. For this investigation, one hundred thirty-two eggs were obtained from 120 Japanese quails grown on a deep litter system. Egg Weight (EW), Egg Length (EL), Egg Width (EWT), Yolk Height (YH), Yolk Diameter (YD), Albumen Length (AL), Albumen Height (AH), Yolk Weight (YW), Shell Weight (SW), Shell Thickness (ST), and Albumen Diameter (AD) were all measured, and Egg Surface Area (ESA), Unit Surface Shell Weight (USW), Egg Index (EI), Shell Ratio (SR). According to the findings, age significantly affected egg weight, body weight, yolk diameter, shell weight, egg surface area, and unit surface shell weight (P<0.05). However, all other parameters were not affected by age (P>0.05). Furthermore, increasing egg weight had a negative effect on egg shape index and egg yolk ratio. Most of the internal egg quality traits studied were negatively affected by increasing the eggshell ratio.

This study sought to assess the adequacy and appropriateness of the contents for the attainment of the NCE Physics curriculum objectives. The study covered 24 Colleges of Education and 60 lecturers. Both descriptive and inferential statistical techniques were used to analyze the data gathered in the study. The results showed that the contents of the NCE Physics curriculum are adequate and appropriate for the attainment of the stated objectives. It was recommended that sufficient courses and periods are allocated to practical lessons and laboratory management adequately.
