The researcher identified all basic skills that involved in the course description of Boxing (1) for Second year, Faculty of Physical Education in Port-Said. And through reference survey he designed eight tests to measure these basic skills and proceed all scientific coefficients, Content validity, Stability, Intrinsic Validity and discriminatory ability which reached the required rate for conduct the factor analysis. One hundred students in second year in faculty of physical education in Port-Said responded to the proposed eight tests in the period from 16-17 / 3/2016. The researcher used (SPSS) software for conducting statistical treatments. In light of the factor analysis using components Principal method and after orthogonal rotation, extracted five factors represent five domains cover the basic skills as follows: (Lead hand Straight punch(Jab), Rear hand Straight punch (Cross), The speed of one combination punch, The speed of Jab-cross combination punches, Stance & foot work). Consequently, established a testing battery to measure the performance of some basic skills in boxing, which included all proposed skill tests were characterized by high factor validity because of their high loading values in a factor which measures a particular domain.

It is expected that by improving the efficiency and reliability of PV technology, large markets will be created at the end of this decade which in turn will result in a declining price of implementation of the technology. The prospects of local manufacture are considered

The main objective is to select the optimal system configuration for supplying the electrical load of an Egyptian isolated village. Design calculations are carried out using three different techniques which are: Heuristic approach, loss of power supply probability indices, and HOMER software analysis. The life cycle cost (LCC) analysis is also conducted to assess the economic viability of designed system. As for determining the optimal PV panels tilt angle, three cases are studied. The paper also shows the effect of electricity price on PV standalone system, and grid extension

Researchers used a Quasi-experimental and descriptive method. For the Quasi-experimental method, the total sample size was (15 employee) who Stayed in the job for two consecutive years (2012/2013, 2013/2014) and received their evaluation of job performance from VPDQ-NU. For the descriptive method, researchers used the results of Internal Audit action records and designed a questionnaire to achieve research objectives. Twenty-two employees in VPDQ-NU responded to the questionnaire. The result of this research from three sources (Quasi-experimental - Internal Audit action records - Designed questionnaire) shows that there is positive effectiveness of ISO 9001:2008 to improve job performance of employees in VPDQ-NU. Based on this research, a key recommendation is the mainstream implementation of ...

This examination is based on a simple two-route traffic network. The ...
