This investigation was carried out to get more information on the effect of fat content on the characteristics and storage stability of beef Shawarma at refrigerated conditions. Four different formulations of beef Shawarma, free lamb fat (FFS), 5% low lamb fat (LFS), 10% medium lam fat (MFS) and 12% high lamb fat (HFS), were prepared, stored at 4°C after packaging in poly propylene pouches, and subjected for pH, TBA, objective colour measurements, bacteriological, and sensory analysis every 3 days. The results indicated that addition of lamb fat reduced pH, redness of colour, increased from TBA, lightness of colour, count of TVC, Psychrotrophic, Enterobacteriaceae and Coliform bacteria of Shawarma. It was also improved from the tasts and aroma acceptability, increased from colour lightness and softening of the texture of cooked Shawarma. During storage at 4°C for 12 days, a gradual lower in pH, lightness of colour, total acceptability, step wise rise in TBA, pale colour, softness of texture and load of determined bacteria of Shawarma were observed especially in products containing high fat.

This study was conducted at the experimental station of Al-Balqa’ Applied University, Jordan to investigate the effect of compost tea on `Neoton` tomato cultivar seed germination and seedling vigor under greenhouse conditions. Seven treatments of 100 seeds each were used. The treatments were; 0:0, 1:1, 1:20, 1:40, 1:60, 1:80, 1:100 of compost: water, respectively. The seeds were germinated in a sandy loam soil mixed with rounded peat pellets (Jiffy -7) in a greenhouse with 23±1 C° temperature and 77% humidity. A randomized complete block design was used with three replications. Treating the seed with compost tea significantly reduced the number of days for germination, compared with the control treatment. The least number of days for germination (almost 3 days) was achieved by applying 1:40 compost: water. The shortening of time between seed sowing and seeding emergence is desired by vegetable growers as it gives them an advantage of earlier transplanting. Compost tea improved seedling vigor by producing taller seedlings with larger stem diameters, which lead to improved crop yield. Accordingly, using compost tea had improved seed germination and seedling vigor of the tomato cultivar `Neoton`.

Bollworms resistance to most registered insecticides has become a major obstacle to their successful chemical control with conventional insecticides. Therefore, field experiments were conducted at Sakha Agricultural Research Station in 2010 and 2011 cotton seasons to study the efficiency of four new mixtures (M) of insecticides, i.e. chloropyrifos + cypermethrin (M1), chloropyrifos + lufenuron (M2), flufenoxuron + alpha-cypermethrin (M3) and thiamethoxam + lambda-cyhalothrin (M4) and two conventional insecticides, chloropyrifos and alphacypermethrin, against cotton bollworms, Pectinophora gossypiella (Saund.) and Earias insulana (Boisd.). Also, their side effects on associated predators were studied. In 2010 season, M3 and alpha-cypermethrin in three successive sprays of each proved to be the superior recording 81.58 and 79.85% reduction in larval infestation, respectively. M4, M1 and chloropyrifos came in the second order without significant differences causing 77.38, 76.65 and 75.27% reduction, respectively. M2 was the least effective with reduction percentage of 74.15. The results of 2011 season showed the same trend of effect for all the tested compounds. According to their side-effects against associated predators, the tested toxicants could be arranged descendingly as follows, alpha-cypermethrin (81.00), M4 (77.96), M3 (76.68), M1 (69.02), M2 (66.07) and chloropyrifos (64.28) % reduction. The obtained results indicated that, the new tested mixtures of insecticides did not exhibit additional advantages in control of the cotton bollworms comparing to the conventional toxicants, where they showed approximately the same effectiveness against the pest and were harmful to the associated predators. Moreover, cross-resistance could be developed after repeated application of these mixtures.

Conventional insecticides exhibited negative effects on environment components and natural enemies. The tested noval insecticides, viz pyridalyl, emamectin-benzoate and indoxacarb compared to chlorfluazuron were evaluated against 2nd and 4th larval instar of Spodoptera littoralis (Boisd.) laboratory strain and their latent effects on some biological aspects were studied. Also, field persistence residues of these tested compounds against field strain of this pest were estimated via determination of Lt50 values. On basis of LC50 values, emamectin benzoate was the most effective compound, followed by indoxacarb and chlorfluazuron, while pyridelyl was the least toxic one, where the LC50 values were 0.539, 5.218, 29.83 and 39.32 mg a.i./L after 48 h, while the LC50 values were 0.278, 2.732, 7.198 and 27.3 mg a.i./L after 72 h from exposure, respectively against 4th larval instar of S. littoralis. From these results, the toxicity of the tested compounds increased with the increasing in the exposure time and decreased by increasing the larval instars. The latent effects of the tested compounds according to sublethal concentrations against 4th instar larvae of laboratory strain were significantly decreased in pupal duration, pupal weight, percentage of normal pupae, adult emergence, fecundity, fertility and adult longevity compared to the control, while these compounds increased significantly larval duration and malformed pupae. Based on the semi-field application, pyridalyl and emamectinbenzoate proved to be the most effective in initial and residual activity causing 100 and 54% mortality for pyridalyl and 100 and 42.13% for emamectin-benzoate, respectively, while indoxacarb was the least effective. Also, pyridalyl show significant, superior persistence residual activity against 4th larval instar of the field strain with Lt50 valued 7.74 days, emamectin-benzoate and chlorfluazuron come in second order, with Lt50 5.59 and 5.56 days, respectively, indoxacarb showed the shortest (1.4 days). From the results, pyridalyl and emamectin-benzoate could be used into Integrated Pest Management against Spodoptera littoralis under field conditions.

The present work was carried out at the Flower and Ornamental Plants Research Gardens, Faculty of Agriculture, Alexandria University, Egypt during the years 2009,2010 and 2011. The aim of this study was to evaluate the effects of saline water irrigation on the parameters that affect the landscaping potentials of a local variety of Pelargonium zonale, L. (Red) plants and also surveying the common landscaping uses of it in the green areas in Alexandria city. Different saline water treatments (1,2,4,6,8,10 and 12 ds/m) were applied to Pelargonium zonale, L. plants besides the control treatment. Generally, increasing saline water level significantly decreased all the vegetative growth parameters (plant height, plant diameter, stem diameter, number of main branches/plant and number of leaves/plant) , compared with the control treatment. Also, saline water treatments resulted in significant reductions in the aesthetic and landscape uses of the plants (growth shape, plant condition, number of inflorescences /plant and flower intensity and quality), besides they delayed the flowering time. Pelargonium zonale, L. plant showed tolerance to saline water level till 6 ds/m. Severe damage occurred to plants starting from September when they irrigated by the high saline concentrations i.e. 8, 10 and 12 ds/m. Surveying the landscaping uses of the plant in the green areas showed a wide range of various uses i.e; in low or raised beds, around trees trunks, in borders, on side of paths and walkways and in containers…etc. It can be generally recommended that Pelargonium zonale, L. plants can tolerate saline irrigation water treatments up to 6ds/m and still having good landscaping potentials and values.

It is of the at most importance to know much about the nutritional and health status of Egyptian adolescents, since in future they will be working people in all areas. In particular rural adolescents as in Menoufia governorate should have much attention, as the rural was neglected many years ago. A total numbers of 60 females and 60 males, 11-14 years of age were chosen randomly from the preparatory schools of Qusina city– Menoufia governorarate. Anthropometric measurements were performed. Questionnaire included Socio-economic parameters, Food habits and daily intake of different nutrients was filled via interview. Statistical analysis was carried out by SPSS Statistical Program. It was found that nutritional awareness was low for both genders in many items especially for boys calling for targeted nutritional awareness program. Daily intakes were low for Energy, Fat, Fibers, Vits. (A, D, C, niacin, Folat ), minerals (K, Ca, P, Fe, Zn). Health status was not satisfying for both girls and boys as well.

A Laboratory study was carried out for three predators; Cryptolaemus montrouzieri (Mulsant), Nephus crucifer Mogulones (Coleoptera:Coccinellidae) and Diadiplosis hirticornis (Felt) (Diptera:Cecidomyiidae) as biocontrol agents for Grapevine Mealybug, Phenacoccus madeirensis Green (Homoptera: Pseudococcidae). The study investigated some biological parameters under laboratory conditions at temperature of 25±1˚C and R.H. 60-80% and a light duration of 9 hr.
The generation time of C. montrouzieri (Mulsant), N. crucifer Mogulones and D. hirticornis was 27.37±1.82, 36.5±3.22 and 18.8±0.26 days, respectively. The average longevity of males and females of C. montrouzieri (Mulsant) was 20±0.42, 27±0.20 days respectively in compare with 21±0.31, 30±1.12 and 8±0.13, 10±0.22 for males and females longevity of N. crucifer Mogulones and D. hirticornis respectively. Predation rate of the females and males of the two predators, C. montrouzieri (Mulsant) and N. crucifer Mogulones on nymphs of Phenacoccus madeirensis was 522±7.42, 453±8.38 and 228±7.91, 202±8.48 nymph respectively, whereas, the predation rate of the larva of C. montrouzieri (Mulsant), N. crucifer Mogulones and D. hirticornis was 756±23.27, 350±16.03 and 287±11.53 nymph respectively.
The obtained results showed that the prey host plants; Carpobrotus edulis, Aptenia cordifolia and Delosperma brunnthaleri caused death to the larvae of Cryptolaemus montrouzieri (Mulsant), Nephus crucifer Mogulones (Coleoptera:Coccinellidae) and Diadiplosis hirticornis (Felt) (Diptera:Cecidomyiidae), and were not susceptible as host plants whereas, sprouted potato tubers were suitable for laboratory rearing of the three predators.
Rearing of C. montrouzieri (Mulsant), N. crucifer Mogulones and D. hirticornis (Felt)is recommended on Phenacoccus madeirensis Green (Homoptera: Pseudococcidae) as prey and sprouted potato tubers as host plants.

The obtained results showed that the prey host plants; Carpobrotus edulis, Aptenia cordifolia and Delosperma brunnthaleri caused death to the larvae of Cryptolaemus montrouzieri (Mulsant), Nephus crucifer Mogulones (Coleoptera:Coccinellidae) and Diadiplosis hirticornis (Felt) (Diptera:Cecidomyiidae), and were not susceptible as host plants whereas, sprouted potato tubers were suitable for laboratory rearing of the three predators.
Rearing of C. montrouzieri (Mulsant), N. crucifer Mogulones and D. hirticornis (Felt)is recommended on Phenacoccus madeirensis Green (Homoptera: Pseudococcidae) as prey and sprouted potato tubers as host plants.

This study aimed mainly to study the acceptance range farmers for practices concerning adaptation to climate changes, and then the impact on productivity and crop net income. The descriptive, quantitative and statistical analysis in addition, stepwise-multiple regression and image double logarithmic deltoid are used, A questionnaire is designed and administered to a random sample of 155 farmers in Villages, El-Abadya, Nedaiba, and Sharnob of Damanhour district, El-Beheira Governorate.
From analysis study to farmers acceptance level for practices concerning adaptation to climate changes and reducing the impact of high temperature on the productivity of agricultural crops, that it has a negative impact on net farm income: it has concluded a large number of results, including the following:
1- It turns out that 49% of respondents are aware of and familiarity with manifestations of risk posed by climate changes and its negative impacts on agricultural production.
2- Show a relative decrease in the level of respondent, I acceptance for practices concerning adaptation to climate changes, that the percentage of respondents low and middle acceptance together 74.2%, while the respondents high acceptance accounted for only 25.8% of the total respondents farmers.
3- Show that each of the following variables: age, educational level, social participation official, sources of agricultural information, the attitude towards change and accept new ideas, and net farm income annual, is negligible when developing agricultural Extension Policy geared towards farmers to adaptation to climate changes, and reduce the adverse effects of high temperature and that negatively effect on the productivity and net farm income.
4- From study the problems impeding on the acceptance practices concerning to climate changes, it turns out that these problems in descending order are the emergence of a negative impact on the effectiveness of pesticides (60.4%), high temperature helps to increase evaporation, the need for the plant to rates quench relatively higher at the time decreasing the water resources, the lack of improved varieties of seed resistant to high temperature, spread of weeds insects and plant diseases in different crops, especially in the summer season, and low productivity per crops, especially in the summer seasons, and low productivity per feddan of different crops is relatively a result of high temperature and then a negative impact on net farm income (41.7%).
In light of the results of this research could be reached several recommendations can be used to raise the level of farmers' acceptance of practices concerning adaptation to climate changes and reduce its negative effects on agricultural production.

During recent years, considerable effort have been focused on using antimutagens to modulate the genotoxic effects of the mutagenic antineoplastic drugs. Therefore, much attention has been paid to the research of naturally occurring agents (especially in diet) that are able to stimulate defense mechanisms of the organism.
Therefore, the aim of the present study is to evaluate the possible protective (antimutagenic) role of Camel milk against the genotoxic effects of a widely used antineoplastic drug “cisplatin” in gametic cells of male mice in vivo.
The 50 adult male Swiss albino mice were divided into five groups:
Gr. I: treated with distilled water and considered as control group.
Gr. II: treated with camel milk (33ml/kg, b.wt.).
Gr. III: treated previously with cisplatin (0.5mg/kg, b.wt.).
Gr. IV: treated with camel milk and followed after 2h. with cisplatin (33ml/kg 0.5mg/kg, b.wt.).
Gr. V: treated with camel milk and cisplatin at the same time (33ml/kg + 0.5mg/kg, b.wt.).
The analysis of data obtained from the dominant lethal assay revealed that the drug was highly effective in inducing dominant lethality after treatment with cisplatin, especially in the first, second and fifth weeks. This implies that the spermatozoa, late spermatid and primary spermatocytes were the most sensitive and highly affected stages by this treatment.
On the other hand, pre & simultaneous treatments with camel milk treatment with cisplatin showed a noticeable decrease in the dominant lethal values in the same stages affected by cisplatin treatment only. It is obviously that the pre- treatment with camel milk and followed by the drug was the more effective treatment in reducing the dominant lethal values than that of the simultaneous treatment observed in the majority of examined weeks. This protective effect of camel milk could be attributed to the scavenging ability to trap free radicals of some of its components like vitamins and minerals. or it has some antioxidant effect.

Cotton varieties, Coker30, SP8886, Lachata, Montana, Halab33, AC22 and Gourd26, and all their F2 half diallel crosses were planted at Al-Hawija, Kirkuk Governarate in 1st of May, 2012 using randomized complete block design with three replications to study general and specific combining abilities for parent and crosses respectively and estimation of phenotypic variance components and some genetic parameters for characters: plant height, number of fruiting branches per plant, number of bolls per plant, boll weight, seed index, lint index and seed cotton yield per plant. results obtained from analysis of variance showed that mean square of genotypes, general and specific combining ability was proven to be significant for all characters except that of genotypes and general combining ability for number of fruiting branches. The variety Lachata appeared as a good general combiner, and (SP8886 x Halab33), (Lachata x Gourd26) crosses as good specific combiners for larger number of characters. The variances (additive, dominance and environmental) appeared significant from zero for all characters, except dominance one for number of fruiting branches, and the dominance variance was higher than additive one for all characters. The total genetic variance was high as compared with environmental variance for all characters except number of fruiting branches and boll weight. The average degree of dominance was higher than one for all characters indicating the presence of over dominance with exception of number of fruiting branches. Narrow sense heritability ranged from 17.96% for lint index to 35.24 for boll number, as was low for boll weight, seed index and lint index and moderate for other characters, while broad sense heritability ranged from 7.64% for number of fruiting branches and 85.12% for boll number, as was low for number of fruiting branches and boll weight, moderate for plant height and high for other characters. Genetic advance as percent from character mean in the third generation was moderate for boll number and seed cotton yield where reaches in them 16.227% and 12.996 respectively, while it was found to be low for other characters.
Cotton varieties, Coker30, SP8886, Lachata, Montana, Halab33, AC22 and Gourd26, and all their F2 half diallel crosses were planted at Al-Hawija, Kirkuk Governarate in 1st of May, 2012 using randomized complete block design with three replications to study general and specific combining abilities for parent and crosses respectively and estimation of phenotypic variance components and some genetic parameters for characters: plant height, number of fruiting branches per plant, number of bolls per plant, boll weight, seed index, lint index and seed cotton yield per plant. results obtained from analysis of variance showed that mean square of genotypes, general and specific combining ability was proven to be significant for all characters except that of genotypes and general combining ability for number of fruiting branches. The variety Lachata appeared as a good general combiner, and (SP8886 x Halab33), (Lachata x Gourd26) crosses as good specific combiners for larger number of characters. The variances (additive, dominance and environmental) appeared significant from zero for all characters, except dominance one for number of fruiting branches, and the dominance variance was higher than additive one for all characters. The total genetic variance was high as compared with environmental variance for all characters except number of fruiting branches and boll weight. The average degree of dominance was higher than one for all characters indicating the presence of over dominance with exception of number of fruiting branches. Narrow sense heritability ranged from 17.96% for lint index to 35.24 for boll number, as was low for boll weight, seed index and lint index and moderate for other characters, while broad sense heritability ranged from 7.64% for number of fruiting branches and 85.12% for boll number, as was low for number of fruiting branches and boll weight, moderate for plant height and high for other characters. Genetic advance as percent from character mean in the third generation was moderate for boll number and seed cotton yield where reaches in them 16.227% and 12.996 respectively, while it was found to be low for other characters.
