Asmaa Hussein | Rawia Gamal | A. Refaat | A. Abdel-Salam | K. Ramadan
A total of 75 pyogenic samples were collected from patients examinated for pyogenic infection in Sednawy hospital and Elmokhtaber laboratories. S. aureus isolated from pleural fluid out of five S. aureus (+ve coagulase, MSSA) exhibits resistant against all the concentration of Ciprofloxacin 0.5-20, Gentamycin 0.5- 5.0 µg/100µl and Amikacin 1 µg/100µl. The highest potent of phytoextracts either extracted by water or methanol was detected by clove comparing with mint, thyme, sage and garlic, whereas garlic essential oil gave completely abolish of S. aureus (P.F). The highest synergism was obtained in combination between the lowest inhibitory concentration of Gentamycin 10 µg/100µl or Vancomycin 1 µg/100µl or Amikacin 2.5 µg/100µl with thyme Eso (1:3), which resulted to increase the efficacy by 4.4 or 1.5 or 1.6 respectively comparing to recommended dose of the tested antibiotics alone. Increasing the concentration of garlic essential oil (GEso) from 10 up to 100 µl/well increment the efficacy of inhibition up to 10, 3.7 and 4.5- fold when standard dose of Gentamycin, Vancomycin and Amikacin were used individually against S. aureus P.F. The minimum bactericidal concentration of garlic essential oil was recorded at 2 µl/ml as it resulted to reduce the count to be 0.04%. Analysis of garlic essential oil by GC-MS dedicated six sulfur compounds represented 88.8644% of total detected compounds in garlic essential oil.

2017
Hanan Ghaly | Mona Emam | Manal Salah
The poultry production sector occupies an important position among the animal production sectors, as one of the main sources of animal protein in Egypt, with a value of about 32.4 billion pounds, representing about 28.9 % of the value of animal production in 2014. This is due to the features of this sector of the short production cycle, the speed of capital turnover, as well as the high economic return. The problem of the study is the large variation in poultry prices between production areas and consumption areas, Indicating an inefficient transport system, which is considered one of the most important marketing services for this fast food commodity death under the prevailing climatic conditions, thus ensuring that they reach the consumer as quickly as possible. The study aimed is to propose the best transportation model to transport poultry production from surplus with poultry to those of shortage with poultry governorates, to reach the shortest distance marketing to minimize transport costs and time. The study used the transportation problem as one of the operation research tools to rationalize the poultry redistribution between surplus and shortage governorates during three scenarios. The study showed under the assumption of the first scenario (production and consumption are expected firming), that the expected quantity to be transported to the shortage governorates to be about 817.4 thousand tons represent about 25.3% of the total production of the republic during the year 2020, Under the proposed model, the least cost of the transfer is estimated at 69.9 million units/km / ton, are estimated quantities transported about 2.5 million tons, represent about 78.1% of the total production at the level of the republic of that model estimated at 3.2 million tons during 2020. The study also showed that under the assumptions the second scenario (lower production 10% and consumption firming), that the expected quantity to be transported to the shortage governorates to be about 850.7 thousand tons represent about 29.2% of the total production of the republic, Under the proposed model, the least cost of the transfer is estimated at 76.9 million units / km / ton, are estimated quantities transported about 2.2 million tons, represent about 75.8% of the total production at the level of the republic of that model estimated at 2.9 million tons. Under the assumption of the third scenario (Production firming and lower consumption 10%) that the expected quantity to be transported to the shortage governorates to be about 702.3 thousand tons represent about 21.7% of the total production of the republic, Under the proposed model, the least cost of the transfer is estimated at 573. million units / km / ton, are estimated quantities transported about 2.5 million tons, represent about 78.1% of the total production at the level of the republic of that model estimated at 3.2 million tons. The study recommended the use of scientific methods to rationalize the transport process between the governorates thus achieving cost and time to transfer at least on the side and the other side reduce wastage circulation which serves to provide the appropriate poultry prices.

2017
F. Mohamed | K. Abdel-Hamid | Genesia Omar | Basma El-Safty
This study was conducted to examine explant density and source on production of in vitro potato microtubers, as well as survey of different newly-introduced potato cultivars for their microtuberization capacity at the Plant Tissue Culture Facility of the Department of Horticulture, Suez Canal University between 2014 until 2016. Results indicated that as culture density from single node explants increased, microtuber number and yield/petri dish were also increased. However, at the lowest density (10 explants/petri dish), the % tuberization and the average microtuber weight increased significantly over the higher densities (20, 25 and 30 explants/petri dish). Potato microtuber production from plantlets grown in vitroon microtuberization induction medium (liquid over solid media) was also studied using 5, 10 and 15 plantlets per jar.Results showed that microtuber number and yield/jar increased gradually with increasing plantlet density. However, on per plantlet basis, microtuber number increased at the lowest density. Microtuber yield/jar increased significantly at the highest density (1099 mg/jar) compared to 563.6 mg/jar at the lowest density. Average microtuber weight was also affected by culture density and genotype. At the lowest density, microtubers were significantly heavier than at the high density, and the cv. 'Safrane' recorded the highest weight per microtuber. Regarding the effect of explant source on microtuber production, results indicated that the use of single node explants derived from the top of the plantlet produced more microtubers than those taken from the basal part, or 3 node segments. Explant source also affected microtuber yield/dish. Single nodes from the top produced the highest yield compared to 3-nodes segment from the top (205 vs. 104.8 mg). The highest mean microtuber fresh weight was obtained from the culture of 3-node layered segment from the plantlet base, while single nodes from the top recorded lower microtuber fresh weight. The highest microtuber fresh weight was recorded in cv 'Universa' (114.3 mg) using single nodes from the plantlet base. Differences among the tested potato cultivars in microtuber production were detected.

Decline of grapevine due to soil borne fungi was surveyed during 2013- 2015 summer growing seasons at El-Fayoum, El-Gharbeia and El-Beheira governorates, Egypt, Syndromes of declined grapevine plants included growth retardant of shoot system and root-rot as well as decrease of grapevine fruit yield quality. Isolation trails from root of declined trees of different grapevine cultivars i.e., superior, flame seedless, King robi and crimson was carried out. The most soil borne fungi associated with root-rotted grapevine were Fusarium oxysporum Schlechtend, Fusarium solani (Mart.) Sacc, Botryodiplodia theobromae, Rhizoctonia solaniKuhn and Macrophomina phaseolina(Tassi) Gold. Fusarium spp. are the main fungal associated with different infection types of declined root of grapevine either a singly or in combination with B. theobromae or R. solani as second infection type and third infection type with B. theobromae + R. solani. Under soil artificially infested with 5% (w/w) of each fungal isolates inocula of fourteen isolates obtained were varied for causing wilt and root-rot symptoms of grapevine trees and reducing growth parameters plant height, root length, root size, fresh and dry weight of shoot and root than the control. Botrydiplodia theobromae isolate No. (7)was the most caused root-rot and disease severity of shoot and root of grapevine plant(100%) followed by Fusarium avenacum caused (87.5%) of root –rot and disease severity of shoot and root. Fouthermore, Fusarium avenacum isolate was the most fungal isolate in reducing growth parameters expect root length. This is first record that Fusarium avenacum as a causal organism causing root rot disease of grapevine in Egypt.

Superior grapevines fertilized with compost, biofertilizers namely (Bacillus megatherium, Bacillus curculanse and Azotoacter Chroococcum), humic acid and two slow release fertilizers namely ( rock phosphate and feldspar ) as a partial replacement of mineral N fertilizers during 2013 and 2014 seasons. Using all substitutes of mineral N fertilizers was favourable than using mineral N alone in enhancing all growth characters, total chlorophylls, nutrients, yield and berries characteristics. Both nitrite and nitrate in the juice were greatly declined in all N management treatments that included the application of all N sources. The best results with regards to yield and berries characteristics of Superior seedless grapevines were recorded on vines that received 60g N, 60g P and 120g K/ vine/ year ( mineral sources) plus compost II ( 40% cattle manure + 60% rice straw ) at 16 kg./ vine+ the three biofertilizers namely Bacillus megatheium, Bacillus circulanse and Azotobacter chroococcum + humic acid each at 10ml./ vine/ year.

This study was carried out during 2013-2014 and 2014-2015 seasons at a private farm located at Tokh district, Qalubia Governorate. Strawberry fruits ˝festival cultivar˝ to study the effect of active (7.5% O2 +15% CO2 or 10% O2 +10% CO2) and passive modified atmosphere packaging (MAP) on preserving the quality parameters and extend the shelf life of fruits during storage at 0˚C plus shelf life at 10˚C.The results showed that active MAP inhibit the weight loss and decay percentage, maintained fruit texture, ascorbic acid, titratable acidity (TA) and decrease in color development during storage and shelf life. Passive MAP was less effective in reducing the loss of fruits texture, TA and ascorbic acid content. Untreated MAP (control) gave the highest values of weight loss and decay percentage and lowest values of texture, becoming more red and poor appearance after 15 days of storage at 0˚C + 2 days at 10˚C. The results showed also that the optimum gas composition of MAP tests for strawberry was 7.5% O2 +15% CO2. No decay was observed in active MAP at 7.5% O2 +15% CO2 during the storage period plus shelf life. Furthermore, it also retarded texture, color, titratable acidity and ascorbic acid content. Finally, the study concluded that storage of strawberry fruits at active MAP of 7.5% O2+ 15% CO2 improved storability of fruits, and maintained fruit quality and gave fruits with good appearance till of 15 days at 0˚C + 2 days at 10˚C without decay. The shelf life of strawberry after harvest can be extended to 3 days at 0˚C + 2 days at 10˚C by this treatment.

The current study was performed to investigate effect of three water regimes as well as, three different soil conditioners on the yield and fruit quality of tomato. The studied water regimes were namely; 60, 80 and 100% of class A pan. However; the tested soil conditioners were “soil hanz”, “Olygo plus” and “Bioconditioner”. Impact of the two investigated factors was studied separately, as well as, the interaction. The experiment was carried out at El-Dolify Farm, Khatatba, Monofia Governorate during seasons of 2012/2013 and 2013/2014. Tomato hybrid Yara F1 was used in this investigation. The obtained results confirmed that, using the “Soil hanz” due to the significant increments in all tested parameters related to the yield and the fruit quality. Moreover; interaction between “Soil hanz” and any of the three tested water regimes was significantly the best in number of fruits per plant, average fruit weight, early, marketable and total yield. In addition; it was concluded from the results that; chemical properties of the tomato fruits were improved by applying the “Soil hanz”. Concerning the water use efficiency, it was found that, all of the tested soil conditioners resulted a significant effect related to water use efficiency compared to un-treated treatment (control). Whereas, irrigated the tomato plants under this experimental condition confirmed the validation of using the 80% irrigation regime for irrigation without significant losses in the crop yield.

Identifying the development relation between different sectors in the entire Egyptian economy (2006/2013) through using of social accounting matrix , containing in addition to data on the inputs and outputs of the productive branches in the economy, but among other things also data concerning the distribution of the various kinds of factor incomes over institutional groups and classes, the expenditures made by these groups on different types of commodities, and the savings and investment made by them. The research showed the existence of permanent deficit representing by 1.5% annually which grown especially after the revolution of January 2011, so there where retreat of the rate of growth. So, it was suggested to do more as possible dis aggregate into socio- economic groups. It will be reasonable to dis-aggregate households into socio-economic group which mean In this case do more to the level and pattern of consumption, expenditure and income distribution, that is to say to dis-aggregate Egypt society as follow: - Regional differences (urban and rural-household). - Egypt level of the head of the household. - Access to productive forms of material wealth particularly agriculture and manufacturing wealth. So The foregoing demonstrated the importance of studying the changes in a macro variables which form the economic relations of social accounting matrix annually and can identify deficiencies and take all measures to avoid such shortcomings even took those incremental trend variables where this may include increasing volatility of investments requires more caution in directing those investments among different sectors, or they may be growing incrementally as imports that requires imports to be more identifying from the point of view. The nature and priorities of rationalization of imports and its component so all variables must be viewed in the same way to reach ultimately aims to increase incoming, reduce expenses and create surplus that support development.
اظهر المزيد [+] اقل [-]AN ECONOMIC AND QUANTITATIVE STUDY FOR THE GEOGRAPHIC AND ALLOCATION IMPACT ON FARMLAND INFRINGEMENT IN EGYPT DURING THE PERIOD 2005-2010

Alaa Elsabea
Farmland infringement for the purpose of construction has become a serious problem in Egypt that negatively affects the average per capita of arable land and soil fertility in Egypt. On the other hand, this situation negatively affects Egypt's self-sufficiency rates of agricultural commodities, agricultural income, and employment in rural areas. However, farmland infringement is completely forbidden by the Egyptian agricultural legislation. In this regard, the current research aims at evaluating the impact of the Geographic and placement impact on Farmland infringement in Egypt during the period (2005-2010). This study recommend the importance of reduce farmland infringement in different Geographic places, to increase the Egyptian agricultural production, raise Egypt's self-sufficiency rates of agricultural commodities, and reduce the deficit in agricultural trade balance, and reduce the problem of unemployment in rural areas. Moreover, the current study used descriptive and statistical analysis to achieve its goals. The main results of this research showed that the total area of agricultural land that had been infringed during the period (2005-2010) reached about 4031 feddans during the period (1993 –1995), increased during the period before revolution (1996 2010-) to 28788 feddans and increased more after revolution during the period 2011- 2014 to ( 38046) feddans. By calculated the total yearly average of farmland infringement in Egypt, the result show that it was about 30.8 feddans during the period (1993 –1995), increased during the period before revolution (1996 2010-) to 43.3 feddans and reduced after revolution as a total to 34.8 feddans as a result of reducing the rate of farmland infringement in the civilization governorate by intensive security power. On the other hand the farmland infringement in all other this rate had increased in all geographic placements in Egypt. Where the yearly rate of farmland infringement in Delta of Egypt, Meddle Egypt and upper. Egypt reach about (43.1, 49.5, 41.2) feddans respectively before revolution, increased after revolution to (712.1, 405.8, 354.5) feddans respectively. It is clear that the delta Egypt has the highest yearly rate of farmland infringement, so it is important to control this rate in future. Besides, the results showed that the most important reasons behind farmland infringement by construction in Egypt are the dummy variable representing the Geographic and placement for the governorates’ and time. The economic model shows the increase of yearly average of total farmland infringement by about 74.4 feddans and the result was significant at the level of significance 1%. Moreover the yearly average of farmland infringement for Delta of Egypt, Meddle Egypt and upper Egypt by about (287.9, 101.7, 95.4( respectively. On the other hand, by using the dummy variable of piecewise to describe the situation after and before revolution in the different geographic and placement of governorates the results show the increase of the farmland infringement after revolution in delta of Egypt from 1136.4 to 2704.3 feddans and the results was accepted significantly at the level of 1%. The results show also the increase of the farmland infringement after revolution in middle of Egypt from 206.7 to 492 feddans and the results was accepted significantly at the level of 1%. Furthermore the results show the increase of the farmland infringement after revolution in Upper Egypt from 254.2 to 605.1 feddans and the results was accepted significantly at the level of 1%. However, the results showed that the farmland infringement after revolution in Egyptian civilization governorates decreased as a results of strong security from -34.5 to -82 feddans and the results was accepted significantly at the level of 1%. Finally, the research recommends strengthening the importance of protected the Egyptian agricultural land specially in the highest geographic and placement governorates especially in delta of Egypt, middle and upper of Egypt by achieving the balance of investment between all these geographic and placement governorates and establishment the necessary desert villages to meet the needs of Rural households.
