This study depends on the analysis of recorder information in special document (questionnaire) prepared for this purpose and includes some demographic factors such as age، gender، socioeconomic level، occupation، head hairs long and education level of parents…..etc. The total number of samples was (2170) students, (371) student were infected, their ages were (6_14) year.The number of infected samples were registered by direct examination with the naked eye for the heads of the students, the number of lice instars were recorded by using magnifying hand lens and the lice instars were isolated from infected samples using special combs to remove lice from an infected hairs.The results of this study reveals highly significant differences in pediculosis prevalence between male, and female which was (19.41، 80.59)% respectively. The results reveals also that high number of infections were in the ages (7, 6, 9) year which was (20.49، 19.14، 12.2)% respectively.It reveals also that there is highly significant differences between infected students and head hairs long, high infected cases recorded in long hair students compared with short hair students which was (55.53، 44.47)% respectively.We also found that the family size has significant effect in pediculosis prevalence, high infections was in family size (9 and more person) compared with family size (3_5) person which was (44.47، 13.21)% respectively.The study also showed presence of highly significant differences between pediculocides which are used in lice killing، Nyda and Kwell-p are more effective in killing ratio (80.43، 75.96)%, while the lotion Tic-Tac revealed less killing ratio (38.46)%.And it is found that the factor (live with relatives) is the most important factor for the transmission and prevalence of pediculosis between students, the ratio of infection is (33.15)% compared another factors.

The study included isolate and diagnose some fungi from possible contamination sites in Al-Ramadi city. And inoculated the liquid culture media contaminated with differing concentrations of lead and chromium by this fungus and two periods 7 and 14 days. results showed the fungus Fusarium sp. records the highest rate of removal of lead and chromium, and the duration of has no effect mentioned on the rate of removal of the lead and chromium, as the relationship between increase in lead and chromium concentration in the liquid media and the ability of fungi on removal was inverse.

This study included the collection of 52 dental swabs samples from patients suffering from infection of the teeth, the microscopic and biochemical tests was conducted and a selective media were used for the diagnosis of bacterial isolates that were isolated. The results showed the represented of Streptococcus mutans with infection rate 30.7%. The effect of fourteen antibiotics were studied toward 46 Streptococcus mutans isolates by disk diffusion method and the most resistant one to antibiotics was selected that was possessed pattern of multiple drug resistance towards(11-12) antibiotic. The virulence factors of the bacteria was investigated and the results showed the ability of these isolates to Biofilm, formation and production of Haemolysin, bacteriocin, protease, gelatinase, and sidrophores. Sesamum seeds were collected and diagnosed, oil was prepared and cellular toxicity and its PH were evaluted and the antimicrobial activity of oil against Streptococcus mutans by disk diffusion method was performed. The study showed that the Sesamum oil has a highly inhibition effect against Streptococcus mutans. The results of the statistical analysis showed the significant difference to the antibiotic synergistic with Sesamum oil, and developing isolates in the culture media containing Sesamum with minimum inhibition concentration changed their sensitivity towards the antibiotics compared with sensitivity before treatment, the isolate lost its ability to produce biofilm,and production of haemolysin, bacteriocin, and gelatinase, and reduced production for protease, while Sidrophores production was not affected.

The purpose of the study is to mix some medicinal plant powders with the food diet and to compare them with the Amberolium antibiotic and to study their effect as dietary aids in improving the hematological , serological, and productive characteristics of the broiler chickens (Rose 308).The four types of medicinal plants were added to the Rose308 broiler Rosemary ,peel of pomegranate, pine and willow plants, and treatment of amberolium was added to water at a concentration of 0.5 g / L. our research includes studies the following : complete blood pictures, biochemical blood parameters ,and all the results oversoften to SSD statistic programs.The results of the study showed that the cumulative performance characteristics of the period (1-42 days) showed significant differences (P< 0.05) For the treatment of control compared with other treatments. It was found that the best treatment in improving the performance characteristics when mixed with the diet and calculating the length of time of breeding period and the body's resistance to diseases and the percentage of losses is the treatment to which the pomegranate powder was added compared with the production characteristics of the other treatments and compared with the control , And the treatment was reduced from the loss rate. The efficiency of the pomegranate peel powder to the type of active ingredient may have been widely used in commercial medical treatments, and the blood parameters ratios of this treatment were closely correlated with the control ratios. As it had an active role in increasing the amount of(Hb , RBC and Platelate) and lower the levels of ESR compared with control and the rest of the other transactions, either serological factors which include: (Total serum protein, albumins, uric acid, creatinine)& (Lipid TC, TG, HDL).It was also found that giving some natural extracts of plants has led to a significant stability of the serological factors. (lipid TC, TG, HDL), and some natural extracts of plants have resulted in significant stability in the results, The final results of our study found that peel of pomegranate powder was the best treatment in terms of improvement of the performance traits and the indicators of the hemolytic , serological and ionic characteristics, while the lowest of the above indicators was in the powder of rosemary leave.

The aim of this current study is to focus on the histopathological changes that happens to the midgut of the cotton leaf worm Spodoptera littoralis (Boisd) larvae especially in the Peritrophic membrane as a main defense line against the occulosion bodies OBs (A crystalline protein matrix which occludes the nucleocapsids) of the Spodoptera littoralis nucleopolyhedrovirus from a local Iraqi isolation that was used as a biological control factor to control this pest. The high specialty of the baculovirus when used as a biological control factor for certain insect families has an important role in full control programs to control pests, especially the SpoNPV virus which is highly specialized in infecting the cotton leaf worm S. littoralis larvae. And it was pointed out by results that there was dissociation and disintegration in the midgut Peritrophic membrane of the larva of the cotton leaf worm at the forth larva stage after 24 hours of exposing them to semi-synthesized nutrition with OBs of the SpoNPV. The microscopic test of the cross section of the larva's midgut showed that after 72 hours of viral infection virus particles have speeded through the rest of the inner tissue of the digestive system and invaded it to reach the fat bodies and tracheal system up to the dermis tissues and the outer cuticle cells of the larva. According to the results of the histopathological study of the infected S. littoralis with the SpoNPV, the virus is considered to be an effective, specialized and ecological safe biological control factor to control this serious pest.

Multi-parent crossover has been proven its ability to address many of combinatorial optimization problems such as the traveling salesman problem and the vehicle routing problem with time windows. The successful use of multi-parent crossover arises from its abilities to enhance the search performance via utilizing information exchanged by more than two parents and inheriting by offspring. These parents are selected according to one of the selection mechanisms. Selecting the most appropriate parents for a crossover process might leads to improving the effectiveness of genetic algorithm. Therefore, this work investigates the effect of selection mechanism on the efficiency of multi-parent crossover. To test this, seven selection mechanisms have been used; random selection mechanism, roulette wheel mechanism, stochastic universal sampling mechanism, tournament selection mechanism, best selection mechanism, single best-couple random selection mechanism and couple best- single random selection mechanism. The performance of the proposed algorithm is tested using Solomon VRPTW benchmark. The experimental results show the superiority of multi-parent crossover that employs the selection mechanism which selects the outstanding individuals to form most of parents over multi-parent crossover that employ other selection mechanisms. This demonstrates the efficiency of employing best parents in a crossover process that can assist the search process to attain a better solution.
