Huda H.I. Mohammed | Magda H. Alaam | Nessrien M.N. Yasin | S.A. Hafez
The present work was conducted to study the effect of red palm oil (RPO) and super red palm olien (SRPOL) on the nutritional parameters of rats suffering from hypercholesterolemic. The vitamins (E, A, D and K) and β carotene were determinate by HPLC and indicated that RPO and SRPOL are considered the richest vegetable oils of antioxidant specially α- tocopherol and β carotene. Thirty male rats weighting approximately 210 grams were divided into five groups, each group containing six rats. Group G1 fed on basal diet as a control negative group. Group G2 fed on basal diets containing 2% of cholesterol as a control positive group and the other groups G3, G4 and G5 fed on the same diet used in group G2, yet the corn oil was replaced by RPO in G3 and SRPOL in G4, Meanwhile, group G5 was fed on the same diet used in group G2 and supplemented with a drug contained Lipitor Atorvastatin (20 mg/Kg BW rat daily by stomach tube). Concerning biological evaluation all the studied dietary oils compared to positive control group caused an decreases in serum LDL-c and TC and significantly increased HDL-c over the feeding period of experimental rat groups, thereby decreased the TC/HDL-c and LDL-c/HDL-c ratios. Aspartate transaminase (AST), alanine transaminase (ALT) enzymes and albumin in rats serum were generally decreased by RPO, SRPOL and drug Lipitor compared to positive control group. Also urea, creatnine and uric acid levels in rats serum were significantly decreased by the studied oils and drug. However, a significant increment in the activities of glutathione peroxidase (GPXs), catalase and total antioxidant were observed in blood of hypercholesterolemic rats treated with RPO, SRPOL and drug. As such, the treated groups showed a significant decrement in malondialdehyde (MDA) in plasma.

Hoda G.A. Taha | B.E. Morsy | Eman Amin
The study aimed at maximizing the utilization of rice straw and the economic return of rice straw recycling, leading to an increase in the economic return of the farms, which in turn leads to increaseing the added value of the agricultural sector on the one hand, and preserving the environment on the other hand. Rice straw, due to the increase in plant waste year after year, and the decrease in environmental awareness among the majority of farmers. The study was conducted at the level of Sharkia governorate and through the geographical distribution of rice straw at the level of the Sharkia centers. About 10.3% of the average production of Sharkia Governorate during the study period. The study relied on the first two sources in the preliminary data obtained from the questionnaire form. The second source was the published secondary data published by the research authorities in the process of recycling agricultural waste. Eightyfive percent of the study sample had an idea of recycling. The largest source of their knowledge is the role of the agricultural association and the agricultural supervisor, and the farmers' proposals for tobacco The number of straws on the eastern level was estimated at 49.7 thousand pounds. If they were recycled, they would achieve a material return of 24 million pounds, and the amount of hay at the level of the republic was estimated at 2.91 million tons. In addition, it was found that the center of Zagazig ranked first in terms of the amount of rice straw burned in the governorate (the most needy centers are aware of the pollution of the environment, which increases the risk that it is considered the highest place Population density in Sharkia governorate.

The study aimed to identify and compare changes in consumer spending patterns in general and food expenditure in particular in both rural and urban areas during the period (2004 / 20052014 / 2015) Moreover and the economic and monetary changes affecting the standard of livinghas also made in Egypt. The study was based on quantitative and descriptive statistical methods such as arithmetic mean, rate of change and percentages, estimating the marginal slope of expenditure, and the elasticity of expenditure of the main food groups, and use of some quantitative analysis methods as a test of the difference between the average of two independent samples, (2004/05, 2014/2015), as well as some studies and research related to the subject of the study. The results showed that the percentage of expenditure on food and drink in both rural and urban areas decreased from the total annual expenditure per capita in 2014/2015 compared to 2004/2005 and that it ranked first among the various expenditure groups during the two study periods and vice versa to the low rate of expenditure on housing in rural areas, the urban expenditure rate increased during 2014/2015. The results showed that the relative importance of urban rural food expenditure, which was reflected in the reduction of the rural-urban food gap, increased from 27.6% to 14.5%. And vice versa, the percentage increased of the rural- urban nonfood gap, from 50.6% to 42.8% during the two study periods. However, the statistical is no significance of the difference between the average of two samples for the total expenditure, food and non-food between rural and urban during the two periods. Results also showed an increase in expenditure on some food groups such as meat, vegetables, cheese, eggs, fish and non-alcoholic beverages, and the decrease in per capita expenditure on cereals and bread in both rural and urban areas during 2014-2015 compared to 2004/2005 The results showed the variation in the elasticity of the expenditure of the food and drink group in both rural and urban areas, some of which were necessary and some of them were morenecessary during 2004/2005. However, they increased per capita in rural areas for all food commodities during 2014-2015, However, most of the food commodities in urban areas is necessary commodities. With reference to the political and monetary changes that occurred during the last ten years, the results of the study showed that the percentage of families living below the poverty line in the rural areas and their urban rise in 2014/2015 compared with 2004/2005, which means that the urban poor are more affected by their rural, The percent age of households living below the absolute poverty line in both rural and urban areas decreased in the second year compared to the first year. The percentage of non-poor households in both rural and urban areas increased in the second year compared with the first year, which indicates improvement Relative to the living conditions of some rural families, While in urban areas, the decline in the proportion of semi-poor families and the increase in the proportion of both poor and non-poor households makes the change in living standards either positive or negative, but the study suggested that there was a transmission to those who were on the edge of poverty to below the poverty line, A change in the consumption pattern, which was affected by the high prices of most food commodities, especially meat and poultry and try to find different alternatives, whether from fish or from eggs and milk derivatives.

Eman A. El-Menofy | Omnia I. Ali | A.H.T. Kandil
In this work, sodium bentonite (Bn) was used for removal of alizarin red S (ARS) from aqueous solution using batch technique. Fourier transform infrared spectroscopy and X-ray diffraction were used to characterize sodium bentonite. Different parameters that would affect ARS dye removal such as initial pH, contact time, initial ARS dye concentration, bentonite dose, and temperature were explored. The realized data from kinetic studies demonstrated the high fitness of pseudosecond-order kinetic model for better interpretation of the experimental data. The adsorption isotherms studies showed that Freundlich isotherm had a high correlation coefficient among the studied isotherm models. Thermodynamic studies proposed that ARS adsorption onto Bn was spontaneous in nature at the lower temperatures and exothermic.

growing seasons of 2013-2014 and 2014-2015, in a private farm at El-Salheya El-Gedida City, Ismailia Governorate, Egypt, to investigate the effect of rice straw (RS) as alternative to sandy soil (SS) and drenching applications of potassium humate (K2-HA) at 2 g/l, potassium silicate (K2SiO3) at 5 g/l, and seaweed extract (SWE) at 0.5 g/l on improving growth of sweet pepper (capsicum annuum L.) plants under deficit irrigation every 2 (I2), 3 (I3) and 4 (I4) days in addition to daily irrigation (I1) as control. Plant samples were taken at 90 days after transplanting to record leaf area, shoot fresh and dry weights, in addition to, determination of leaf relative water content (LRWC), concentrations of N, P, K and Ca. Mean values of drenching applications showed significant increase in the growth parameters ;shoot fresh and dry weights, leaf area, LRWC, as well as, concentrations of N, P and Ca in the two seasons comparing to untreated control and the best results were due to K2-HA followed by SWE then K2SiO3. The highest concentration of K was obtained by K2SiO3 followed by K2-HA then SWE. Plants were grown on RS showed significant increase in LRWC comparing to plants were grown on SS. Plants were applied with I2+ K2-HA+ SS showed the highest significant value of shoot fresh weight, shoot dry weight, leaf area, N, P and Ca concentrations followed by I2+SWE+SScomparing to control plants applied with I1+ SS without drenching applications. Plants were grown on RS showed significant increase in growth parameters comparing with control plants but less than those were grown on SS. The best results were achieved by I3 + K2-HA+ RS, I3 + SWE+ RS, I4 + K2-HA+ RS. Plants were grown on rice strawunderI3 irrigation and applied with K2-HA or SWE showed significant increase in N, P and Ca concentrations, while, under I4 irrigation an increase in N and P concentrations was obtained by K2-HA.The highest concentrations of k were observed with plants grown on SS under the highest level of irrigation deficit I4 by K2SiO3.It could be concluded from the present study that rice straw could alleviate the negative effect of low water supply and applications of K2-HA and SWE are recommended for enhancing sweet pepper growth and nutrient elements uptake under water deficit conditions.

The present Avian Influenza epidemic in Egypt is consider one of the major problems facing the poultry field and caused by circulation of genetically and antigenetically diverse influenza H5N1 viruses. This problem is controlled by applying vaccination. The objective was to determine the AI H5 recombinant vaccines efficacy (rHVT-H5, rFP-AI-H5 (Scotland and Ireland), k rND-AI and k rBuc-AI+ND) against classical and variant field HPAI H5N1 viruses in comparison to the traditionally inactivated whole AI virus vaccines as K R H5N1 / Egy, k H5N2 and k combined AI+ND vaccines. A single dose of the different types of vaccines either recombinant or inactivated whole virus vaccines was administered at different ages of chicken. Eight chicken groups were vaccinated with 8 vaccines and challenged after 4 weeks post vaccination to measure the protection %. Fecal and tracheal swabs were taken after 2 day post challenge to detect viral shedding. It was found that, live rFP-AI-H5 of both Scotland and Ireland strains induced poor clinical protection with high level of virus shedding. While, inactivated rND-AI, live rHVT-H5 and inactivated rBuc-AI+ND vaccines induced high protection rates ranged from 86.7% to 93.3% against both classical and variant HPAI viruses with a decrease or suppression of viruses shedding. In a parallel way, the inactivated whole virus AI vaccines either K R H5N1 / Egy, k H5N2 or k AI+ND induced a protection rates ranged from 85.7% to 100% with a high decrease in virus shedding levels. The data clearly indicate that inactivated whole AI virus and inactivated recombinant vaccines confers high levels of clinical protection with suppression in viral shedding compared to that of live recombinant vaccines except rHVT-H5 vaccine which induce a great level of protection and decrease in viral shedding in SPF chicken.

The good design of irrigation system is one of the main steps of extent the life of the irrigation system, as well as increase the cultivated crop productivity by choosing the proper components of irrigation system control head unit ( such as pump, motor, filters, main line pipe, fertilization device, and the different control unit attachements). Different types of control unit components are used according to the system conditions for irrigation of agricultural areas. It is very difficult to find an expert at desired time and desired place for choosing correct control unit which are varied in different types and models. In this study, this problem was to be tried to solve by designing of an expert system for choosing proper components of control unit in irrigation network. A rule-based program named TSDI-ES (Technical Specification of Drip Irrigation-Expert System) was coded and compiled using Microsoft visual basic 2013 language. Generally, the expert system database obtained from commonly used all components of control unit in irrigation network in Egypt. selection of all components of control head unit in irrigation network were determined by taking into consideration the following parameters: water resource, irrigation methods, irrigation area, crop pattern, climate, soil properties, and well characteristics. Results of the investigation indicated that it is possible to use the TSDI-ES rule-based program for choosing all proper components of control head unit in drip irrigation network such as pump, filtration unit, fertilizers devices, and flow, pressure measuerement and control devices.

This study aimed to investigate the effect of a mixture of (ZAD) and (Lacto bacillus plantarum) on chemical composition of green corn stover and corn stalks and the effect of these treatments in a metabolism trial on digestibility coefficients , rumen fermentation and some blood parameters. One ton of either green corn stover or corn stalks was chopped into (2-3 cm) and its mixed with 0. 5 cubic metre of water or one cubic metre of water, respectively. They were then mixed with 3%w/w molasses and 1.5%w/w urea and incubated for six weeks. The experiment included six treatments, three of them were on green corn stover and the rest were on corn stalks. The treatments on green corn stover were as follows: (T1) Untreated green corn stover (control). (T2) corn stover + lactobacillus palantarum + ZAD (2litres of ZAD + 1 liter of lactobacillus palantarum / 1ton). (T3) corn stover + ZAD ( 2 liters of ZAD/ 1 ton). The treatments on corn stalks were as follows: (T4) Untreated corn stalks (control). (T5) corn stalks + lactobacillus palantarum+ ZAD (2litres of ZAD +1 liter of lactobacillus palantarum /1ton) (T6) corn stalks + ZAD (2 liters of ZAD/ 1 ton). Eighteen Ossimi male lambs were divided to six group rations for 15 days in metabolism trials. Results indicated that biological treatment on T2 and T3 treatments on green stover and T5 and T6 on dry corn stalks decreased CF and NDF, ADF, ADL contents and increased CP content compared to the control. Feeding lambs on treated green corn stover or treated dry corn stalks significantly (P<0.05) improved all of nutrients digestibility compared with those fed on control. The nutritive values as TDN, DCP and N balance for lambs fed treated green stover or treated dry corn stalks showed significant(P<0.05) higher than those fed untreated and it had the same trend of nutrient digestibility . Adding lactobacillus palantarum + ZAD improved digestion coefficients of nutrients and TDN values compared with control. Results of blood parameter indicated that T2 of green corn stover and T5 of corn stalks had a significant (P<0.05) effect on (Tp, Alb, Glb, A/G) compared to the control and T3 of corn stover and T6 of corn stalks. All values of plasma ALT and AST for all treatments were in normal rang where all treatments had no effect on ALT. However, T2 of green corn stover and T5 of corn stalks had a significant (P<0.05) effect on AST compared to the control and T3 of corn stover and T6 of corn stalks. All values of plasma creatinine and urea for biological treatments appeared to significant(P<0.05) higher values. However, these values were in normal range. Results of rumen parameters indicated that all treatments had no effect on pH and NH3-N. On the other hand T2 of green corn stover and T5 of corn stalks significantly (P<0.05) increased TVF'S. Generally, Adding enzyme with or without lactobacillus to green corn stover or dry corn stalks tended to improved nutrient components , digestibility coefficients, feeding values and nitrogen balance with no adverse effect of animal health .

rosemary and its oil were used to investigate their effects on diabetic and liver malfunctional rats by administrating them with STZ or CCl4 for three weeks. The therapeutic effects of rosemary extracts (alcoholic and aqueous) and its oil against acute hyperglycemia induced by STZ in rats showed a decrease in the levels of fasting and postprandial blood glucose of rats treated with alcoholic extract of rosemary. In addition, results showed a restoration of these levels of the rats treated with aqueous extract or oil to their normal ranges after 3 weeks. There is a significant difference in lipid profile between rats treated with alcoholic or aqueous extracts and the negative control, where, the HDL in group administrated rosemary oil is significantly higher than both positive and negative control. The protective effects of rosemary extracts (alcoholic and aqueous) and its oil against liver toxicity induced by CCl4 in rats showed a significant difference between both (negative and positive control) and the activity of AST and ALT in the rats treated by alcoholic and aqueous extracts of rosemary. The protective effects of the plant extracts against liver toxicant occurred by decreasing the activities of these enzymes. Oil rosemary had restored effect more than both ethanolic and aqueous extracts, but not significant. This protective effect occurred by decreasing the activities of AST, ALT and Alp enzymes. No significant (p≤0.05) differences were noticed among the levels of serum total protein for all treatments compared to the negative and positive controls. The levels of total cholesterol and triglycerides recorded high values for the positive controls compared to the negative control. The protective effects of rosemary extracts against liver toxicant occurred by restoring the levels of these parameters to their normal values.
