Abstract:- The aim is to evaluate the impact on academic training with specialized virtual health libraries (databases and catalogs) available in Institutions of Scholar Education, because there is uncertainty about the appropriate use of these libraries. The research was conducted on the databases available on 2 universities during the academic period August 2015 - February 2016. Using criteria and indicators for evaluating virtual libraries, model quality of university libraries based on fuzzy techniques, Bibliometric and criteria for virtual libraries in health. The study had the participation of 188 students from two universities or groups. The research reveals that for the first group and the second...............

The dynamical behavior of two coupled parametrically excited van der pol oscillator is investigated by using perturbation method. Resonance cases were obtained, the worst one has been chosen to be discussed. The stability of the obtained numerical solution is investigated using both phase plane methods and frequency response equations. Effect of the different parameters on the system behavior is studied numerically. Comparison between the approximate solution and numerical solution is obtained...........

Fuel pump shaft pumping fuel to motor in a heavy duty Diesel Engine. Fuel pump shaft pumping fuel to motor in a Heavy Duty Diesel Engine. This part is operating at very high pressure. Fuel pump shaft to examine the losses during the study, great for work efficiency. In this work the wear behaviors of the cam surfaces have been examined by the fuel pump shaft ANS Triboconditioning ® coating. The camshaft with two cams is used on the work. The cam shaft material is the AISI 4140 steel used in the work. Before coating, surface roughness value is measured to the cam surfaces on the camshaft. Then the cam surfaces are covered with a special coating method. Surface roughness values were measured after coating...................
