The interaction of preservations, growth regulators and cold storage on vase life and quality of Lily (Lilium longiflorum) cut flowers were investigated. Lily cut flowers were treated with 1 ml mol silver thiosulfate (STS), 100 ppm gibberellic acid (GA3), 0.5 ml mol benzyl adenine (BA), 200 ppm citric acid and 4 % sucrose and then were placed in cold storage at 5 ºC for period of 1, 2 and 3 weeks. Vase life (days), fresh weight (%), total chlorophyll (%), total carbohydrate (mg / g d. w.), activity of catalase enzyme content (EU / 1 g f. w.) and amino acid of free proline content (mg / g d. w.) were determined. Cold storage for one week and pulsing with using material of GA3, BA and STS produced the longest vase life, the lowest catalase enzyme activity, the lowest content chlorophyll decreasing, the highest of total carbohydrate content and the lowest amino acid of free proline content.

The interaction of pulsing in preservatives, growth regulators and cold storage on vase life and quality of Chrysanthemum (Dendranthema grandiflora) cut flowers was investigated. Chrysanthemum cut flowers were treated with benzyl adenine (BA), silver nitrate (AgNO3), cobalt sulfate (CoSO4) and sodium hypochlorite (NaOCl) and then were placed in cold storage at 5ºC for periods of 1, 2 and 3 weeks. Vase life, fresh weight, total chlorophyll and total carbohydrate were determined. Cold storage for one week and pulsing with BA and AgNO3 showed longest vase life, the lowest chlorophyll decrease and highest total carbohydrate content.

White coats worn by professionals in the medical field (students of health) or the work in the laboratory (students of Science), goal protect clothing from microbes.  In this study was determined the type of microbial contamination on the white coats and the potential risks of microbes. The study was done by a questionnaire for students and samples swabs of coats for 80 students from the Fac. of Health and Science. The results explained the presence of pathogenic bacteria causing inflammatory and dimples contaminated white coats, such as Erysipelothrio rhusiopathiae causing the h time skin, Micrococcus luteues causing chronic inflammatory skin ; bacterial meningitis and blood contamination unidentified Organism and Kocuria kristinae causing infections of the urinary tract infections, gallbladder and opportunistic bacteria and the spread of  nosocomial  infections, one of opportunistic pathogens. As well as  recorded  high proportion of serious fungi that cause various diseases and contamination of food such as Aspergillus niger ; Helminthosporium spp, Fusarium SPP, and Alternaria alternate . This study suggests that a large proportion of white coats may be a carrier of serious morbidity among female students in colleges is different, especially when not . There are laws and regulations in organizing wear these coats and the way to carry and learn how the daily cleaning of .

The experiment was carried out at the experimental site of Arid Land Agricultural graduate studies and Research Institute (ALARI), Faculty of Agriculture, Ain Shams University, Qalyobia Governorate during the two successive seasons of 2013/2014 and 2014/2015. Fresh bare root strawberry (Fragaria x ananassa) transplants cv. Festival were used in this experiment.The aim of the study was to determine the best irrigation scheduling and better strawberry density to get the best production and quality of strawberry fruits grown in A-shape NFT system. Five irrigation schedules (24 hours (control), ¼ / ½ hour (Sched 1), ¼  / 1 hour (Sched 2), ¼  / 2 hours (Sched 3), ¼  / 3 hours (Sched 4) and two plant density per square meter (21 plants / m2 “PD-1”,32 plants / m2 “PD-2”) and the combinations among them were tested in this experiment. The EC of the nutrient solution was adjusted at the range of 2.0 – 2.5 m.mhos-2 and pH was maintained at the range of 5.5-6.0 throughout the experimental time. The measurements recorded were as follows: number of leaves, % of fruit set, early and total yield and mean fruit weight. Quality measurements included total soluble solids (TSS) (the percentage of TSS was determined by using hand refractometer), ascorbic acid (vitamin C), and fruit acidity. Results indicated that irrigating plants for 15 min every ½ hour increased productivity (mean fruit weight, early yield and total yield) and quality (TSS) but reduced vitamin C and fruit acidity of strawberry. While the irrigating plants every 1 hour reduced number of leaves, set %, early & total yield, mean fruit weight, TSS.

Prices reflect the relative scarcity of resources in terms of planning is based under the free-market mechanisms for price and market signals as an essential mechanism in the allocation of resources and guidance system, Price is also working on consumer directed toward maximizing satisficing  the resources available to them, which leads to maximizing the well-being of the community. The research problem is in direct government intervention in price policy, which may give rise to a variation in the local and indirect world prices lead to non-optimal utilization of the resources used in the production process, which affects the welfare of producers and consumers, as well as on government revenue and the outcome of the state foreign trade. research aims to identify the price differences between local and world prices resulting from price, The policies fish and by estimating the partial equilibrium model to examine the effect influence of the policies of government intervention at all stages of fish flow in the market, by measuring the efficiency of the product, the consumer, the community level, and measurement of well-being at the community level, as well as measurement of government revenues and this may help to measure the efficiency of these policies in achieving its objectives and examine the effects on producers, consumers and the overall economy. The results showed the following   The average nominal protection for fish rate during the study period (1998-2013) amounted to 0.67 i.e. it is greater than zero, which means that the state supports the producers of fish by about at 67% in favor of the producers of fish on the expense of the consumer represented in the higher domestic price for the world price, The results indicate that the concern of the State on promoting fish producers to reduce the size of the gap and reduce the import of foreign currency into force. The study showed also that the expansion of fish production leads to increased foreign exchange earnings by reducing imports and reduce the food gap, where the maximum fish production reached amounted to 1372.0, 1454.4 during the years 2012.2013, respectively, while the maximum foreign exchange earnings reached a maximum in 2012, 2013 amounted to 27067.03. The results of the welfare check gains in producer excess as the average change in the product excess amounted to 3.1336 billion pounds, which reflects the impact of price policy applied, while under the negative values of consumer excess has been achieved loss in consumer surplus, bringing the average loss during the study period of about 5566.88 million pounds. Decline in consumer surplus was due to the local consumer bear the superiority of market forces and the presence of protectionist policy to support the product and taxing the consumer, leading to increased consumer spending as a result of the purchase of small quantities at high prices, leading to lower prices of consumer welfare.

This study was conducted to investigate the effect of biological treatments to improvement on the in vitro digestibility disappearance for rice straw.  The parameter used in this study includes; gas-production, IVDMD, IVMOD and pH value. The experiment was divided into seven treatments: 1st treatment: considered as control group was used 3g from straw only. 2nd treatment: Fibrolytic enzymes group 0.3g with 3g from straw. 3rd treatment: Fibrolytic enzymes group 0.4g with 3g from straw. 4th treatment: Saccharomyces cerevisie group 0.3g with 3g from straw.   5th treatment: Saccharomyces cerevisie group 0.4g with 3g from straw. 6thtreatment: The mix group between fibrolytic enzymes group 0.3g and Saccharomyces cerevisie group 0.3g with 3g from straw. 7thtreatment: The mix group between fibrolytic enzymes group 0.4g and Saccharomyces cerevisie group 0.4g with 3g from straw.   The results showed a significant increase (P<0.05) of 6th group in gas production as compared with 3rd group at the beginning of the experiment. Also the 3rd group showed a significant increase (P<0.05) in gas production as compared with 5th group after 10 hrs. from the period of incubation. It has been observed that there was a significant increase (P <0.05) in the 3rd group in gas produced as compared with 4th  and 5th  group after 12 hrs from the period of incubation. The result also showed a significant effect (P <0.05) in the 2nd and 6th groups in the gas production as compared with 5th group after 24 hrs the period of incubation. It has been observed after 48 hrs the period of incubation, there was a significant effect (P<0.05) in gas produced in all treated groups as compared with 5th group. It has been noticed from the experiment that there was result a significant increase (P<0.05) in 5th, 6th groups of pH value as compared with 2nd and 4th groups. The results showed a significant effect (P<0.05) in the 3rd group in IVDMD as compared with 6th group, Similarly, there showed a significant effect (P<0.05) in the 1st, 3rd, 5th, 6th, 7th groups in the IVDMD as compared with 4th group. There was also a significant effect (P<0.05) in the 3rd in IVMOD value than that with 6th group. It has been shown that there was a significant effect (P <0.05) in the 6th group of IVMOD value as compared with 2nd, 4th and 7th groups. Finally it has observed that there was a significant effect (P <0.05) in the control group (1st), 5th and 7th groups in IVMOD value as compared with 4th group. It was concluded from this study that addition of fibrolytic enzymes and a combination of fibrolytic enzymes and saccharomyces cerevisie could improve digestibility of rice straw in vitro.

Faba bean (Vicia faba L.) seeds cv. Misr 1  were treated with Bion (5 mM), salicylic acid (5 mM) as chemical inducers as well as Paenibacillus polymyxa and Trichoderma harzianum as biotic inducers to study their effect on the infection with Rhizoctonia solani and Fusarium solani f. sp. fabae under greenhouse and field conditions.           Under greenhouse conditions (Agricultural Research Centre, Giza) all treatments induced reduction in the percentages of pre- and post-emergence damping off caused by R. solani or F. solani f. sp. fabae compared to untreated control. The highest percentage of survived plants was achieved from the inducer Bion (92 % and 88%) compared with untreated control (40% and 36%) in the presence of R. solani or F. solani f. sp. fabae respectively. Meantime, there was no significant difference between the Bion and the fungicide Rizolex –T (3 g/Kg seeds) treatments. However, all treatments caused significant increase in the figures of plant height, shoot and root dry weight, nodules number/plant and nodules dry weight over the control treatment grown in infested soil by R. solani or by F. solani f. sp.  fabae. The highest values of all growth parameters under study were recorded on faba bean plants check (healthy plants) grown in disinfested soil followed by Bion and Rizolex –T treatments in the presence of R. solani or F. solani f. sp.  fabae. There was no significant difference between Bion and Rizolex-T treatments with exception of nodules number and nodules dry weight /plant in the presence of R. solani. On the contrary, there was significant difference between Bion and Rizolex-T treatments with exception of plant height in the presence of F. solani f. sp.  fabae.           Under field conditions at Giza (Giza Governorate) and Etay El-Baroud (El- Behira Governorate) Agricultural Research Stations during winter season 2013-2014, all the treatments significantly decreased the percentage of pre- and post-emergence damping-off and increased the percentage of survived plants compared with untreated control in two locations with exception of post-emergence percentage figures at Giza Agricultural Research Station. Regarding survived plants, there were no significant differences between the Bion (89.5% and 86.5%) as well as Rizolex-T (90.9% and 88.8%) treatments compared with untreated control (68.3% and 64.3%) at Giza and Etay El-Baroud Agricultural Research Stations respectively. However, all inducer treatments significantly improved growth parameters (i.e. plant height, number of pods/plant, seed weight /plant and one hundred seed weight) as well as yield compared to the untreated control in the two locations. Higher increase in seed yield (ton /feddan) was obtained with Rizolex-T and Bion treatments (62.2% and 57.9%) respectively, followed by salicylic acid and P. polymyxa with (39.4% and 28.4 %) respectively, increasing over the untreated control calculated as means of the two locations.         Activities of peroxidase (PO), polyphenol oxidase (PPO) enzymes and phenol content were determined in faba bean plants treated with different inducers. Bion treatment showed the highest increase in PO and PPO activity, total and free phenols followed by salicylic acid treatment in the presence of R. solani or F. solani f. sp.  fabae.

The research aims to identify the current situation of red meat, poultry meat, and fish in the Kingdom of Saudi Arabia. Forecasting, food gap until 2020 for these meat and its impact on the future prospects for its imports has also examined. This will help to design reliable policies for the production, import and export of meat in Kingdom of Saudi Arabia. The research problem is  the increase of domestic consumption of meat due to population growth and inadequate domestic production. This summation the contribute to increase the deficit in the agricultural and food trade balance. The study referee to relative stability in the average production of red meat in the Kingdom during the period (2000-2014) amounting to 120.2 thousand tons, while production increased from both poultry and fish at an annual rate of about 6.2, 3.85 thousand tons, representing about 1.2 %, 4.6% of average annual production of 514.8, 82.2 thousand tons, respectively. At the same time red meat consumption in Saudi was relatively stable and swings around average during the study period amounting to 238.8 thousand tons, while increasing consumption of poultry meat, and fish at an annual rate significantly statistically amounted to about 39.7, 6.2 thousand tons, representing about 4.0%, 3.3 % of the annual average consumption of about 1003.9, 186.6 thousand tons, respectively.  Results revealed that avirtual food gap in Saudi Arabia in each of red meat, poultry meat and fish amounted to about 118.6, 489.2, 104.4 thousand tons, respectively. However, according to the results, food gap has increased from both red meat and fish to reach about 169.2 , 247.5 thousand tons, respectively, While domestic production of poultry meat has achieved surplus in all the years of study, an average of 139 thousand tons , which indicates the presence of extravagance in consumption with an average share of Saudi Arabia's per capita, 39.7 kg , which is close to three times, as much as the average  international per capita, estimated at 15.0 kg average for the period (2011-2014). Results of using Holt Winter,s two- parameters model to predict showed increasing of the virtual food gap from red meat , poultry meat and fish, reaching around 168.95, 822.0, 136.3 thousand tons respectively during 2020.
