Abstract
The use of electronic valves is commonly available. yet, the most
common is the techniques of communications as prod casting transmitter that
are used by these valves in addition to their use in communication tools as far
distance telephone, electronic measuring techniques , and others.
In this study, an attempt is endeavored for improving the efficiency of the
vacuum micro- valves(GI-19b) through activating their internal surfaces by the
use of ionic pumping which is used for treating valves which are out of order
(because of sedimentation some materials and oxide on its poles). The
existence of these materials and oxide increase the sum of current leakage

Show MoreThere are main methods of scientific research, and that the researcher's choice of the appropriate methodology for scientific research is one of the most important rules on which the researcher must rely in order to prepare scientific research properly. There is no doubt that the methodology of scientific research is of great importance that they all agree on the preparation of accurate scientific research. Scientific research is an organized research that does not come by chance, but comes as a result of the activity of the mind. It is theoretical because it relies on theories for the purposes of perceiving the proportions and relationships between things, and everyone is subjected to testing and experiment.
This study aimed to investigate the impact of fish oil levels on the growth performance, feed efficiency, and body composition of common carp. The study divided 56 common carp into four treatment groups and fed diets containing different levels of fish oil over 56 days. Results showed significant differences in growth performance and feed efficiency between the treatments. The T3 (1.5% fish oil) and T4 (2% fish oil) groups showed the highest weight gain and most efficient feed conversion ratio, suggesting that 1.5% fish oil may support growth outcomes like those with 2% fish oil. Body composition analyses revealed favorable protein-to-fat ratios, suggesting improved nutrient retention and lean growth with reduced fish oil levels.
