Despite the remarkable development of the use of e-commerce, however, the use of e-commerce in Egypt is still small compared to many countries in the world, suggesting many problems facing use of electronic commerce it impedes the development of agricultural exports through which it can be made to the European Union in general and to the most important importing States of agricultural products in particular. The research was aimed at identifying the development of the Internet and e-commerce worldwide in general and comparing it with its development in Egypt and what is the role of e-commerce in marketing horticultural products to the European market and what the facilities it has done to give trade the flexibility required to achieve the required increase in Egypt's exports and what export opportunities it has shown to exporters to help them reach many European markets. These statistics point to the increasing use of e-commerce by Arab States in general and to increase them in Egypt in particular, showing that Egypt's total traditional trade value for these two years 41.311 in million dollars and the value of e-commerce from it was estimated at 10.82 million dollars, which means that e-commerce accounted for about 35 percent of the value of traditional trade.   Statistics from internet users in the Arab region indicate that there is a 14% increase in the number of users in the years 2015, 2016, which is a positive sign that e-commerce is continuing in growth among the Arab world population Egypt continues to lead the Arab region with an average of 29 million Internet users, with up to 56 percent of them benefiting from it, buying and shopping online. The research focused on clarifying the role of e-commerce in the development of Egyptian agricultural exports and the completion of export transactions, as it was found that the use of e-commerce accounted for some 68% of the sample of exporters in the study, while there were those who used both e-commerce and traditional trade and accounted for about 27% of the total study sample. There were important questions about e-commerce that had been surveyed through personal interviews and a number of 30 questionnaire form export and import companies representing the sample of the study and selected in the intentional sampling method given because it is a company that works in the export of vegetable and fruit products as a basic activity, with about 88% of the respondents confirming that used electronic commerce to identify or access new markets, while the respondents also explained that the majority of them had other sources Other than e-commerce (Fairs and Exporters ' Union publications) rely on them to market their exports. Some 90% of the exporters in the study indicated that they could not dispense with e-commerce in dealing with importers as they contribute significantly to facilitating procedures, contracting shipping, reducing export costs and reducing risk costs.

This study aimed to investigate the attitude of three nematode and phylloxera resistant grape rootstocks (Freedom, Ramsey and SO4) through the micropropagation stages till be micrografted by Superior scions. During that the effect of paclobutrazol (PP333) on rootstocks stem diameter, transverse sections in graft union regions and acclimatization of resulted micrografts were studied. The results proved that the most effective sterilization durations using 1% NaOCl were 15 min for Freedom and SO4 explants as they achieved 0.00 and 0.00%of  contamination and 100% and 90% of survival percentages respectively, while 10 min duration was sufficient for Ramsey explants as it achieved 0.00 % contamination and 100% survival percentages. Significantly, Ramsey achieved the highest number of shoots (1.25), Freedom gave the tallest shoots (4.13 cm)and SO4 got the highest leaf number (7.33) all on MS medium. In multiplication stage; Freedom rootstock proved to be the most reacted rootstock as it significantly accomplished the highest shoot number (2.00) when planted on BA medium, the tallest shoots (3.54 cm) when planted on TDZ medium and the highest leaf number on Kin medium. Whereas, in order to get thicker shoots for easier grafting; using of PP333 at 5 mgl-1 significantly was the best for Freedom (3.55 mm) followed by SO4 (3.03 mm) and Ramsey (2.85 mm) rootstocks. In micrografting stage, Superior micrografts significantly achieved the best results on rooted Freedom rootstocksin scion survival (100.00%) and on un rooted rootstocks in scion bud burst (75.00 %), graft union formation (50.00%), rooting (75.00%). On the same trend, Freedom rootstock was more active in cell dividing activity when grafted by Superior cultivar compared to Ramsey and SO4 rootstocks which were very poor in producing callus cells in graft union. Finally, Freedom rootstock grafted with Superior gained the highest survival (100%) after acclimatization.

is study aimed to evaluate the in-vitro antioxidant activities of Moringa Oleifera Lam (MO) extracts, and their protective effects in acetaminophen (APAP)- induced liver injury in rats caused by oxidative damage. The antioxidants activities of ethanolic, aqueous and hexane extracts of different MO edible parts were investigated by DPPH radical scavenging capacity and malondialdehyde (MDA) assays. The ethanolic extracts of different parts of MO were found to have higher antioxidant capacity compared to the aqueous and hexane extracts. The flowers ethanolic extract has the highest total antioxidants capacity among the other different parts of MO follo wed by leaves, pods, roots and finally seeds. HPLC-MS scanning of ethanolic leave extracts showed the presence of flavonoid derivates Apigenin, quercetin and kaempferol in addition to chlorogenic acid.  In the hepatoprotective study, either leaves or pods extracts (300mg/Kg bw or 600mg/Kg bw stomach tube orally) were administrated to rats one hour prior to administration of a single dose of APAP (4g/Kg bw by stomach tube orally). The hepatoprotective activity of MO leaves and pods extracts were followed for 21 days by observed in the levels of liver markers such as alanine aminotransferase (ALT) and the levels of oxidative damage markers including superoxide dismutase (SOD) and malondialdehyde (MDA) and catalase (CAT), wich analysed and compared between groups pretreated with MO extracts +APAP to those treated with  APAP alone. The outcome of this parameters indicate reduction in the severity of liver damage in group treated with MO extracts + APAP and compared to those treated with APAP alone . Also, histopathological examination of liver tissues of rats treated with MO extracts showed an improvement at the end of experiment.  The results of this study indicate the hepatoprotective properties of MO leaves and pods ethanolic extracts against liver injury and thereby signify its traditional use.

The Research  aimed to identify the types of products marketed by the respondents electronically, to identify the marketing methods used by the respondents, and what is preferred, identify the contribution of e-marketing in establishing women's own project, to identify the advantages and disadvantages of e-marketing from the point of view of the respondents, to identify the level of economic empowerment of rural women who market their products electronically, to identify the effect of Independent variables on The dependent variable( economic empowerment), and  to identify the activities and extension efforts in the field of electronic marketing.  The research was based on the social survey approach by selecting a randomly sample of the respondents in Qalyubiya Governorate (90) respondents, (30) respondents with Qalyubiya Facebook groups and (60) respondents were selected through (Open Day) (is a day of rural women show electronic products through Facebook pages). Data were collected during June, July and August 2017 and using frequencies and percentages, Pearson's simple correlation coefficient, Step-Wise analysis to analyze research data.    The most important result are as the follows    1- Most of the products that are marketed electronically are clothing (40%), Beauty Products (26.7%), Household products (7.8%), household  food (7.8%), indicating Products not related to rural products and its products indicates a change in some purchasing habits in the countryside, which can be traced to electronic marketing. 2-(41.1%) of the respondents marketed their products through social networking sites, while (53.9%) of the sample used the usual marketing methods (such as selling in shops, markets) and the use of social networking sites in marketing. Half of the sample (45.6%) prefer marketing through social networking pages, (23.3%) prefer normal marketing, and (31.1%) prefer to use both methods. 3-The results showed that e-marketing contributed to the establishment of women in their own project. About (55.6%) of respondents said that emarketing was easy to market their products, and (51.1%) of respondents said that emarketing encouraged them to do their own project. 4-The most advantages of electronic marketing from the point of view of the respondents is to interact at any time, and get the largest number of customers, and marketing outside the village, and determine the opinion of the customer easily, easy to spread products and easy access to customers through social networking pages, and it has some disadvantages, the most important of which is the difficulty of inspecting the product to ensure the quality (14.3%). It requires follow-up and continuity to the personal page or the group on which the products are displayed (16.4%), the seasonality of the sale, the absence of a fixed salary (6.7%), and (8.4%) of the respondents mentioned that there are no disad vantages for electronic marketing from their point of view. 5- More than half of the sample (58.9%) is in the average empowerment category, while (37.8%) are in the low category, (3.3%) are in the high empowerment category. 6- The results of the study showed that there are four independent variables of the independent  variables, "e-marketing, training, family support, the judgment of the respondents on their project", all of which explain about 41.2% of the variation in the level of economic empowerment of the researchers. 7- All the participants were not exposed to any activities or extension efforts by the extension system.

Two pot experiments were carried out at the greenhouse of the Cotton Research Institute, Agric. Res. Cent., Giza, Egypt during 2015 and 2016 seasons to study the response of cotton plant to application of some nutrients to improve the performance of cotton plant under irrigation of saline water to increase growth, yield and yield components and fiber quality of Giza 90 cotton cultivar.  The experimental design was a split plot design with four replications. Main plots included saline water solutions treatments (control, 2000, 4000, 6000 and 8000 ppm), sub plot included four nutrients application (Potassium Humate, Algex, Poly Ethylene Glycol (PEG) 6000 and Potassein compared with control). The obtained results could be summarized as follows: Irrigation with saline  water over seasons significantly decreased plant height, number of fruiting branches/plant, number of open bolls /plant, boll weight, seed index, seed cotton yield per plant, fiber length, uniformity index, fiber strength and micronaire value,  while, lint % was significantly increased. Nutrients application had significant effect on growth parameters, yield and its components and fiber properties under study, All nutrients treatments gave the highest values of growth parameters, yield and its components and fiber properties as compared with the control in both seasons. In general, plants sprayed with PEG gave the highest averages of plant height, number of fruiting branches/plant. Potassium Humate gave  the highest averages of yield and its components and fiber properties followed by plants sprayed with Algex, while the plants sprayed with PEG as came the last in these respect in both seasons. Interaction between irrigation with slain water and nutrients application by salinity tolerance inducers had a significant effect on plant height, number of fruiting branches per plant,  boll weight,  number of open bolls /plant, seed index, seed cotton yield /plant and fiber quality under study in both seasons. Plants treated with foliar nutrients under salinity condation scored the highest average of growth parameters, yield and its components and fiber properties. Potassium Humate, Algex, PEG and Potassein applications to plants under normal and salinity conditions had positive effects on improving the performance of cotton plants, which increased plant growth and yield especially under salinity conditions.

Energy sources represent one of the most important inputs of the production process without which the production process can't begin or continue. The process of fossil fuels production has Longley been associated with large amounts of emitted pollutants into the atmosphere starting through the industrial revolution at the beginning of the last century and up to nowadays, causing high levels of pollution that have threatened the human presence on earth. Fossil fuels has three main problems: the first is polluting the environment and the second is that it is steadily depleting and the third is that it has a decreasing supply function, contrary to its increasing demand, which has led to a steady increase in its international prices. It is a must and not a luxury. These made the world to produce the biogas and its secondary product "the biogas compost" which environmentally and economically compatible compared to other alternatives offered in the global market.  In Egypt, the problem of fuel is more acute, especially in the desert provinces, where the challenges of shortage of supply of LPGs combine with increasing demand due to rapid population increase with spatial spacing between production  and distribution areas accompanied by transportation, storage and handling risks, In a short period of time, all of which are a constant pressure on the balance of the local market for fuel, especially gas cylinders (LPG). Increasing carbon emissions from different sectors especially transport and agriculture (with regard to the accumulation and unsustainable handling of agricultural wastes) and the industrial sector pose significant challenges to environmental safety in Egypt. Which makes these factors a pressure pathway for the state to encourage the spread of the use of biogas technology in the agricultural sector, especially as it save the foreign currency through the provision of a complete decomposed, free of parasites, and low cost fertilizer in addition to it doesn't cause environmental pollution compared to other high-cost organic fertilizers and extremely expensive and environmentally pollutant chemical ones. The study found that the size of the most common fermenter in the category of small-size fermenters is 6 m 3 because it has a high economic return.  The research concluded that in biogas production units studied in the newly reclaimed areas of three Governorates (South Sinai, Fayoum, Assiut), net profit reached the end of life of the project, estimated at about 15 years, is about 42642 LE. The average annual profit per unit (4240 LE), IRR (15%), and the total cost recovery period of the unit are estimated at (7 years).   A sensitivity analysis of 10% found that    First    Increase costs by 10%     Net profit of LE 40454.  The average annual profit is LE 3424.  Internal rate of return (IRR) 15%  The total cost recovery period for the unit is 7 years.    Second    Revenues decrease by 10%     Net profit of LE 3622.  The average annual profit is LE 3075.  Internal rate of return (IRR) 15%   The total cost recovery period for the unit is 7 years   Third    Increase costs by 10% and decrease revenue by 10% together     Net profit of LE 34014.  The average annual profit is 3000 pounds.  Internal rate of return (IRR) 15%  The total cost recovery period for the unit is 7 years    The study recommends the use of 6 m3 biogas fermenters in the agriculture sector for heating, lighting and cooking purposes especially in newly reclaimed lands to provide energy and organic fertilizers to ensure the sustainability of the environmental resources in these virgin areas and the success of production processes economically.

The study of distribution and field efficacy of egg parasitoids was conducted in several wheat fields in north east of Syria (Amoda, Al-Qamishly, Al- Qehtanya, Al-Jwadya and Al-Malikya) in the 2011 field season. The results of surveys and taxonomy showed that fives parasitoid species  belonging to Scelionidae family and order of  Hymenoptera are: Trissolcus grandis Thomson,  Trissolcus simoni Mayr, Trissolcus semistriatus Ness, Trissolcus vassiilievi Mayr and Gryon fasciatus Priener. The abundant species were T. grand which occurred in all sites and rate parasitism reached to 37.74% to all eggs, and T. vassilievi which occurred in all sites except Amoda and parasitism reached to 32.10%. T. semistriatus recovered in Al-Qamishly, Al- Qehtanya and Al-Malikya and parasitism reached to 16.98%. T. simoni  was recovered only from Amoda, Gryon faciatus only from Al-Malikya. Overall parasitism rates reached 44.17% throughout the season.

The objective of this present study is Studying the effect of crossing and reciprocal cross on productive performance, Fertility and hatchability for local chicken. The experiment was carried out in the farm of the Faculty of Agriculture - Ain Shams University. Their experimental research began when birds from two local breeds 22 week of age, where, sixty chickens (30 Fayoumi breeds, 30 Sinai breeds).were used at 26 weeks of age semen was collected artificially from 12 cocks (6 Fayoumi , 6 Sinai).semen from each cock artificially inseminated 48 female within each breed. Were attribution taken to be a parent stock. They were housed in batteries and then they transferred into individual batteries until the end of the experiment (36 weeks of age). The two breeds were mated and four crosses were produced Male Fayoumi*Female Fayoumi (FF) , Male Fayoumi*Female Sinai (FS) ,Male Sinai*Female Sinai(SS) , Male Sinai*Female Fayoumi (SF) After the second generation hatching ,the resolutely indicated that (FF) breed had the highest Fertility percent while the (SF)cross was the highest Hatchability calculated from the total eggs and also from fertile eggs . and Individual body weight (in grams) was recorded for each sex separately within each breed at 0, 1, 2, 3, 4, 5, 6, 7, 8 weeks of age. Male Sinai*Female Fayoumi (SF) was found to be the best breeds in terms of body weight and vitality and better in food conversion. The most important results observed from this study indicated that the (SF) cross had the best in fertility, the best hatchability calculated from total and fertile eggs, body weight and body weight gain.    So, it could be concluded that, cross procedure could be used in order to achieve genetic improvement from local breeds, which mean the possibility of increasing our production and hence on consumption from our local breeds and reducing on dependence from foreign breeds.

The study aimed to identify an evaluation of pre-service training on the performance of agriculture Faculty students, Mansoura University in the transfer of extension knowledge to their peers in public health field. The data were collected from 504 students representing an accident sample from the second and third levels of the Faculty for determination of the training needs in public health field during the period from October to November 2016 by personal interview. A purposive sample of 12 students was chosen and trained to transfer extension knowledge, the highest needed field, to their peers during the period from September to December 2017.  Arithmetic mean, (t) test paired and (t) test for independent samples were used as statistical tools for analyzing data and deducing results. 1- The highest needed training field from the studied public health fields was smoking and addiction (52.58%). 2- The trained students who evaluated the training session exhibited a high level of satisfaction (87.7%). 3-  There were significant differences (P < 0.01) between the knowledge degree  means of the students before and after the training program implementation related to knowledge transfer in the smoking and addiction field. 4- There were significant differences (P < 0.01 ( between the knowledge degree means of the two groups which received knowledge from the trained specialist and non-specialist students before and after knowledge transfer process in the smoking and addiction field. 5- There were insignificant differences between the knowledge degree means of the two groups which received knowledge from the non-trained specialist and nonspecialist students before and after knowledge transfer process in the smoking and addiction field. 6- There were significant differences in the knowledge degree means between the two specialist groups which methodologically and non-methodologically received knowledge in the smoking and addiction field.  There were significant differences in the knowledge degree means between the two nonspecialist groups which methodologically and nonmethodologically received knowledge in the smoking and addiction field.

The pathogenic and spoilage microorganisms affect human health directly or indirectly and become increasingly important in most countries. Novel antimicrobial agents and disinfectants have become necessary due to the rise of antibiotic resistance phenomena. The current study investigate the inhibitory infect of ANOSAN on pathogenic bacteria and toxigenic fungi. Chemical analysis was performed for ANOSAN. The antimicrobial activity of ANOSAN was carried out using agar well diffusion assay and mean growth inhibition percentage and Minimum Inhibitory Concentration (MIC). The antibiofilm activity was conducted using Biofilm formation assay and the impact of the disinfectant on the preformed biofilm was visualized by Scanning Electron Microscope (SEM). The chemical composition of ANOSAN comprised very low amount of Sodium (0.034%), Chloride (0.01%), Hypochlorite (0.014%) and Organic matter (0.0062%). ANOSAN low concentration showed a broad spectrum of antibacterial activities against Gram positive, Gram negative bacteria and fungi. The MIC (0.781 mg/ml) was observed for Vibrio cholerae, Pseudomonas aeruginosa and Staphylococcus aureus. Sub-inhibitory concentrations of ANOSAN have successfully inhibited biofilm formation of the above mentioned bacterial patho gens. The ANOSAN appeared to be effective as bactericidal against Ps. aeruginosa and Staph. aureus. The time kill assay was observed between (0-6h) and between (0-3h) of exposure for both pathogens, respectively, and the viable bacterial counts remained undetectable after the previous time in a confirmatory experiment. Scanning Electron Microscopy (SEM) was conducted to confirm the antimicrobial activity of ANOSAN against Staph. aureus and Ps. aeruginosa. These data directly illustrate the destructive effects of the ANOSAN on the pathogenic bacteria. This work clarified that ANOSAN water had bactericidal and fungicidal activity along with inhibiting the ability of pathogenic bacteria to form biofilms, thus providing a good alternative to the use of traditional antimicrobials in food industry, pharmaceutical and medical applications.
