Detergents are an undetectable source of pollution, which hidden in most of our daily activities. Detergents could cause harmful effects before they are completely degraded. It is wise to reduce the amount of detergents that usually used by invention new bio-friendly formula contains efficient enzymes such as protease. Screening studies were carried out for one hundred and fifty bacterial isolates with respect to their ability to produce protease(s), after growing on slaughter house wastes (SHW) isolated from El-Khorma governorate,Taif, Kingdom of Saudi Arabia (KSA) at 55ºC, and pH 9. The most potent thermophilic bacterial isolate concerning of alkaline thermostable protease(s) production was identified as Bacillus licheniformis EGT50. Alkaline thermostable proteases productivity by the most potent bacterial isolate was affected by substrate concentrations (solid substrate), carbon source, nitrogen source, amino acid supplements, incubation temperature, incubation period, and inoculum size. Maximum both enzymes production by B. licheniformis EGT50 was obtained  on SHW concentrations, 7.5 %; galactose; diammonium hydrogen phosphate; arginine at 55°C for 72 h. when inoculated by 0.5 ml. The protease production under all optimal conditions was increased many folds from 563.68 to 17825 U/ml (31 fold). The purification fold of B. licheniformis EGT50 alkaline thermostable protease increased to 394.7 after applying Sephadex G200 column chromatography techniques. The enzyme productivity of protease has been determined and the result proved the possibility to use the crude and purified enzymes in biodetergent technology

Farm animals have a high economic importance because of their important products such as meat, milk, hair as well as skin, not only in our country but also all over the world. These animals can be infected by serious pathogens, external and   internal parasites causing severe damage, which result in losses of animal production. Accordingly, the study of external parasites with light microscope and scanning electron microscope were recorded, to clarify the exact composition of species. Also, differences in the morphological characteristics between the two Myiasis species: Oestrus ovis (Linnaeus, 1758)and Cephalopina titillator (Clark 1797), were investigated.

Ultrastructure study revealed two types of fly larvae Przhevalskiana silenus (Brauer, 1858) and Cochliomyia hominivorax (Coquerel, 1858) that causes myasis in Goats in Saudi Arabia, The study recorded that the exact composition of these two genus showed differences in morphological characteristics, which cannot be identified using an optical microscope. All previous studies recorded on the same region never before carried out ultrastracture studied.

The almond seed wasp Eurytoma amygdali Enderlein (Eurytoma amygdale End) is an important insect on almonds Amygdalus spin its plantig regions, causing a large loss in the production. The relationship between the adults of almond seed wasp in five regions:  mid Syria (Homs), Southern region (Al Qunaitera, Swedaa), and the countryside of Damascus (Beet Tema,, Deer Ateah) was studied by ISSR. The results indicated that the females from Homs formed a separated cluster, and the females from Beet Tema and Deer Ateah were the most closed to each other,also the female from  Al Qunaitera and  Swedaa were closed to each other. It was noted that the males separated into two clusters, the first one contained the males from Homs and Swedaa, and the second contained the males from Beet Tema, Al Qunaitera and Deer Ateah.

Olive tree (Olea europaea L.) is one of the most important fruit trees, there is a lot of varieties with the possibility of mislabeling, homogenouses and synonyms, which makes major troubles when having plant material for propagation and breeding programs. In this search, 12 olive varieties (Maw! Istanbul!, Khilkhali Khishen, Dan, Mniekri, Adkam, Doaibli, Mot, Khilkhali Saghir, Karamani Modabal, Mawi abo Shokeh, Sourani, and Abo Shokeh), cultivated in ACSAD Gene bank in Gellin, were characterized by ISSR molecular markers to determine the relationship between these varieties. Depending on quantitive traits the results indicated that these varieties are so close to each other's, ranged from 60% and 85%. It was noticed that Mneikri was apart from the other varieties in its traits, (polymorphic rate was 92.94%).

.The results revealed that The highest proportion of farmers was between 28 and 60 years. Mean values for family size in the different study areas were 5.49, the main occupation of respondents was agriculture (60%) A large share of farmers (70%) received formal education, while (30%) of farmers did not receive any formal education. Farmers in the study area were small-scale farmers, it showed that the average size of land owned was one feddan, the average level of living was 12.19, the average annual gross farm income in the study area was 11362 L_.E per household. All farmers in the study areas were members of the agricultural cooperative, which exist in all villages. Membership of these cooperatives was mandatory for those farmers who had reasonable access to it; 51.5% of farmers have a medium level of cosmopoliteness, 37% have a high level. More than 75% of farmers were falling in the medium level of communication with agricultural information, more than 65% of farmers had a medium level of aspiration, only 1.5% of farmers had a high level of aspiration, The highest proportion of farmers was a medium degree of filiations to community. The results showed that non of the respondents from the sample size had a high level of agricultural modernity, 76.5% had a medium level and 23.5 % only had low level. The coefficients of the logistic model used to investigate factors affecting the modernity of farmers. The chi-square test showed the level of significance of the parameters included in the model (at P 0.01). Modernity of farmers was correctly predicted for 77.5% of the farmers. The factors that contribute to modernity of farmers according to the Wald chi-square statistic were in order of importance: degree of affiliation, cosmopoliteness, family size, farm size, and aspiration level.

This study aimed at identifying the political knowledge and some aspects of political participation of the rural youth, and determining variables that are proposed to relate and explaine the variance of degree of political knowledge and political participation of the rural youth. Data were collected from a random sample of 1100 youth (550 males, and 550 females) in eleven villages at Menoufiya governorate through personal interviews with respondents. The results of the study indicated a low political knowledge degree and political participation degree for the rural youth. The results of statistical tests revealed that there were significant differences between the two groups of respondents (males and females) regarding political knowledge degree and political participation degree. The findings of step-wise multiple regression analysis indicated that: , The most important variables affecting degree of male's political knowledge were education level, participation in developmental projects, cultural cosmoplitness, participation in public election's conferences, participation in social organizations and participation in political parties. These six significant independent variables explained only 37.9% of the total variance of the male's political knowledge degree. , The most important variables affecting degree of female's political knowledge were education level, cultural cosmoplitness, participation in social organizations, socialization and politicalization, geographical cosmoplitness, monthly incom and age. These seven significant independent variables explained only 33.3% of the total variance of the female's political knowledge degree. , The most important variables affecting degree of male's political participation were political knowledge degree, participation in social organizations, participation in developmental projects and cultural cosmoplitness. These four significant independent variables explained only 24% of the total variance of the male's political participation degree. , The most important variables affecting degree of female's political participation were political knowledge degree, participation in social organizations, age, geographical cosmoplitness, family education level and cultural cosmoplitness. These six significant independent variables explained only 15.6% of the total variance of the female's political participation degree. The study were concluded with a discussion of its findings and a number of suggestions for the inhancement of rural youth' participation in political activities were introduced.
