The forage potential of fodder beet (Beta vulgaris L.) grown under the Egyptian agricultural conditions has not been fully investigated. This study was carried out during two successive winter growing seasons (2014/2015 and 2015/2016) in Egypt and aimed to investigate the variations in yield and some quality attributes of fodder beet as affected by three sowing dates (15th September, 15th October and 15th November), three ages at harvest (120, 150, and 180 days after sowing - DAS), and boron application. Total, root, and shoot yields (t ha-1), as well as root and shoot dry matter contents (g kg-1) were evaluated. Fodder beet quality was judged in terms of the variations in the three fiber fractions (NDF, ADF, and ADL), in addition to the in vitro true digestibility (IVTD), and the NDF digestibility (NDFD). A pronounced response in most of the studied parameters to the different sowing dates and age at harvest was detected, while boron application had minimal influence on yield and quality of fodder beet. Early sowing (mid-Sept.) and late harvesting (180 DAS) resulted in the maximum fresh yield amounting to 170 ton ha-1, while a delay in sowing to mid-Nov. resulted in 53% reduction in fresh yield. The maximum dry matter content, on the other hand, was achieved with late sowing (mid-Nov.) and late harvesting (180 DAS). The role of boron in nutrient translocation from shoots to roots was clear in the significant decrease of the shoot dry matter content. However, no effect was observed for the root and shoot fresh yields. Harvesting at 180 DAS lead to the accumulation of the highest significant amount from the three tested fiber fractions (NDF, ADF and ADL). Regarding digestibility, both IVTD and NDFD values, declined with the increase in plant age at harvest. Results of the current study indicated that the fiber fractions of fodder beet roots and shoots were distinguishably lower than other forage crops. Furthermore, the high digestibility of 79% for IVTD and 60%for NDFD for fodder beet roots and comparable values for shoots, emphasize the excellent fiber quality of this crop. Records of the quality attributes of fodder beet, in the current study, in addition to its high yield, suggest that it can complement the high-protein berseem clover feed in critical periods of forage shortage and improve the nutritional value of the produced feed in the winter season in Egypt.

Two Egyptian long staple cotton varieties (Giza 86 and Giza 80) were blended with imported Greek and Russian cottons at 100, 75, 50, 25 and 0 percent of Egyptian cotton component in blend. The objective of the study was to determine the effect of blending, with different percentages, on fiber and yarn properties. The study was set up as split plot design, where the varietal blends were allocated to the main plots and the blending percentages assigned to the subplots. Fiber properties, i.e., fiber length, uniformity and fiber strength values decreased, whereas fiber elongation, mirconaire value and neps count increased, with increasing imported upland cotton percentage in the blend. Differences were also found between Egyptian cotton cultivars where Giza 86 gave higher values for fiber length and strength values, but lower micronaire and neps values compared to Giza 80. Concerning yarn characteristics, most of the studied yarn properties were not affected by varietal blends, blending percentages and their interaction. However, number of neps places were lower for introduced cotton compared to Egyptian cotton. Yarn elongation varied significantly with the percentage of imported cotton in the blend and was highest (5.94) with 50:50% Egyptian to introduced cotton. The correlation between blended fiber properties and yarn characteristics varied according to varietal blend, but, generally, showed negative correlation between single yarn strength and fiber micronaire value (-0.54), and between yarn uniformity and blended fiber elongation (-0.58).

More than 280.000 barley accessions (Hordeum vulgare L.) were recorded in gene banks around the world. Most of the genetic diversity that local or traditional varieties of cultivated crops possess is being lost. The experiment was conducted at the Faculty of Agriculture (Saba Basha), Alexandria University, Egypt, during 2016 to characterize different barley cultivars and lines under different salt concentrations. Fourteen barely cultivars and eight lines were used in the current research. All the tested samples were sown in petri dish (15 cm dimeter) under different salt concentrations (0, 100, 200 and 300 Mm NaCl) using complete randomized design in three replicates. Morphological parameters were selected and measured after two weeks from each replicate. The morphological parameters were germination percentage (%), seedling height (cm) and root length (cm). Grains of each cultivar were squashed and total protein were sequentially separated. One dimensional SDS–polyacrylamide gel electrophoresis was performed to separate the total protein. The genetic relationships among cultivars and lines were measured based on morphological and biochemical markers aiming to use in the future breeding program based on genetic variations. The results revealed significant variations among the tested cultivars and lines under different salt concentrations. Line number 5 and 6 showed the highest mean values of morphological traits under high salt concentrations, while barely cultivars showed different response to salinity levels. The tolerant cultivars showed unique bands in total protein analysis that mean when barely plants subject to abiotic stress such as salinity, plants try to increase the total enzyme contact and some amino acid like proline as defense mechanism for protect the cell wall from damage, this fact was achieved during current results.

This investigation was carried out to identify and evaluate Medicago sativa andTrifolium alexandrinum probability for breeding program based on two bar-coding genes (rbcl and Cox1 genes). Identification of Medicago sativa Baladi 1 was performed through rbcl and Cox1 genes. Medicago sativa Baladi 1 was identified as Medicago sativa voucher G00199095 ribulose-1,5-bisphosphate carboxylase/oxygenase large subunit (rbcL) gene, partial cds; chloroplast (Sequence ID: KJ204375.1) and Medicago sativa voucher Ahrendsen_23 for rbcl and Cox1 genes respectively. Identity values were recorded with 90% of identity for alfalfa, Baladi 1 Genotype ribulose – 1/5 – bisphosphate carboxylase / oxygenase large subunit (rbcl) gene (sequences ID: KJ206375.1) also, identity values were recorded with 91.24% of identity for alfalfa Baladi 1 Genotype, cytochrome c oxiddase bubunit I gene (cox 1) (sequence ID: KJ 204375.1). Trifolium alexandrinum Helaly genotype was identified as Trifolium alexandrinum (Sequence ID: HM850407.1) and Trifolium alexandrinum voucher K-016Hv (Sequence ID: KU234213.1) as rbcl and Cox1 genes respectively. Affiliation of genetic origin was detected for Trifolium alexandrinum with 100 % of similarity with origin source which indicate highly possibility for applying breeding programs comparing with Medicago sativa which reflect the lowest genetic similarity with origin source.

Thiophanate-methyl is an effective fungicide on several food crops. In the present study, dissipation of residue levels of thiophanate-methyl in apple and strawberry fruits under open field conditions were studied using high performance liquid chromatography with diode array detection (HPLC-DAD).The extraction and clean-up were conducted by QuEChERS method. The limit of quantitation and detection were 0.01 and 0.003 mg/kg, respectively. The results suggest that the thiophanate-methyl dissipation curves followed the first order kinetics and its half-life values were (1.01) and (1.26) days for apple and strawberry, respectively. The residues in apple and strawberry were below the codex maximum residue limit (MRL) (0.5 and 0.1 mg/kg) after 8 and 4 days of the application, respectively.

Wheat is the major source of food for human nutrition and a part of daily dietary need in one form or more. There is need to increase its productivity vertically and horizontally. In order to improve productivity of three wheat cultivars, nano- technological fertilizer, common mineral fertilizer and amino acids as foliar applications were tested. Two field experiments were conducted at El-Horaia village, Abou El- Matamir district, El- Behira Governorate, Egypt, during 2014/2015 and 2015/2016 growing seasons, in split plot design with three replications. The main plots included foliar application (mineral, amino acids, nano fertilizer, mineral + amino acids, mineral + nano- fertilizer, and amino acids + nanofertilizer), while three bread wheat cultivars (Sids 12, Sids 11 and Giza 168) were allocated in the sub plot. The obtained results revealed such significant increases in plant height, spikes number/m2, spikelets number/spike, grains number/spike, 1000- kernel weight, grain, straw, and biological yields/fed., as well as harvest index (%) using nano- fertilizer + amino acids during both growing seasons. Meanwhile, the applied mineral fertilizer, alone; gave the lowest mean values of the studied traits. However, “Sids 12” cultivar recorded the highest means values of the studied characters. Spray “Sids 12” cultivar by nano- fertilizer and amino acids; recorded the highest mean values of yield and its components. On the other hand, “Giza 168” cultivar, possessed the lowest ones.

The present study was carried out to investigate the patterns of pink bollworm (PBW), Pectinophora gossypiella, diapaused larval exit from cotton bolls, percent larval mortality after leaving bolls and the development as well as some biological parameters of living larvae. Diapaused larval exit began at March and the number of emerged larvae from immature green cotton bolls that collected from El-Behira (ranged from 22.3 to 106.7 larvae) is significantly higher than the number of emerged larvae from immature green cotton bolls that collected from Alexandria (numbers ranged from 17.7 to 82.3 larvae) during the investigated period. Percent larval mortality in exited larvae at March, April and May from Alexandria cotton bolls (70.3, 64.7 and 52.1%, respectively) is significantly higher than the percent larval mortality from El-Behira (66.5, 57.8 and 46.4%, respectively). The PBW %adult emergence in El-Behira strain is significantly higher than the PBW percent of adult emergence in Alexandria strain during March and April. Fecundity (No. laid eggs / female) and fertility (percent egg hatching) are significantly higher in the moths which emerged from El-Behira strain than from Alexandria strain. This study represents important information about the pattern of PBW diapaused larval exit from the last season cotton bolls which can help in the PBW infestation prediction and mangement.

A study was conducted to investigate the effect of presoaking of sugar beet (Beta vulgaris L.) seeds (polygerm) with gibberellic acid, abscisic acid, or ascorbic acid on alleviation of salt stress at seedling stage. The salinity levels of irrigation solution were 0, 25, 50 and 100 mM NaCl and the presoaking treatments were water as a control, 10 µM GA3, 10 µM ABA, and 0.5 mM ASA for 12 hrs. Seeds were sown in plastic pot containing 0.8 Kg prewashed sand and irrigated three times weekly by 100 mL per pot of one-tenth modified Hoagland solution containing the salt level. After seven weeks from sowing, the whole plants were collected. The results indicated that increasing salt concentration decreased the fresh and dry weight of whole plant, shoot and root, and shoot height of all presoaking treatments. However, shoot/root ratio on fresh and dry weight basis and moisture content of whole plant, shoot and root, chlorophyll content index, and electrolyte leakage were increased with increasing salt concentration of all presoaking treatments. However, presoaking of sugar beet seeds (polygerm) with the GA3, ABA, or ASA showed no significant effect to alleviation salt stress on sugar beet seedlings. However, the interaction between salt levels and presoaking treatments was significant for whole plant and root fresh and dry weights, shoot/root ratio on fresh weight basis, whole plant and root moisture content and chlorophyll content index, while nonsignificant for shoot fresh and dry weights, shoot height, shoot/root ratio on dry weight basis, shoot moisture content and electrolyte leakage.

Mitochondria are a convenient model to understand the oxidative damage induced by various xenobiotic-prooxidants. This study was designed to investigate (1) the possibility of lambda-cyhalothrin (LCT), a type II pyrethroid, to induce oxidative stress response in rabbit liver mitochondria in vitro and its effect on selected parameters and (2) the role of quercetin in alleviating the cytotoxic effects of LCT. Mitochondria were divided into two groups. The first group, mitochondria were incubated for 30 min at 37oC with different concentrations (0, 5, 10, 15 and 20uM) of LCT. In the second group, mitochondria were pre-incubated with (10µM) quercetin for 30 min and followed by LCT incubation for 30 min at 37oC. Following in vitro exposure, LCT caused a significant induction of oxidative damage in mitochondria at all tested concentrations as evidenced by increased superoxide dismutase (SOD) activity and reduced glutathione (GSH) level. However, a significant decrease in the activities of NADH dehydrogenase and ATP synthase (ATPase) was obtained. While the quercetin treated mitochondria showed significant enhancement in all tested parameters except GSH content, there was no significant change. Quercetin showed a significant protection against the cytotoxic effects induced by LCT on the studied parameters. In conclusion, antioxidant quercetin could be able to ameliorate LCT-induced oxidative stress by altering antioxidant defense system and recovered the bioenergetic activity of mitochondria.

Thermoduric and thermophilic aerobic spore-forming bacteria are the common causes of spoilage of pasteurized and Ultra-high-temperature (UHT) milk. The presence of high level of aerobic spore-forming bacteria in raw and recombined milk used in making UHT milk increased the spoilage and/or the reduced shelf life in the final product. In this study, 140 samples of (32) raw milk (RM), (8) skim milk powder (SMP) and (100) UHT milk were collected to isolate aerobic spore-forming bacteria. A total of 210 isolates of heat resistant bacteria were classified according to morphological, physiological and biochemical tests. Out of theses isolates, 144 strains from RM (102), SMP (25) and UHT milk (17) were expected to be Bacillus spp. The isolates were evaluated for proteolytic activity and lactose fermentation, 96.55% of the isolates were able to hydrolyze casein, while 42.76 % of the isolates were able to ferment lactose. Thermophilic Bacillus species were the predominant isolates from raw milk and skimmed milk powder. While, mesophilic Bacillus species were the predominant in UHT milk.

The current research was carried out in 2016 to evaluate potassium Quantity-Intensity parameters and the relation of these parameters to the characteristics of some agricultural soils of El-Dakhla Oasis, New Valley, Egypt. Six surface soil samples (0-30 cm) were collected from different sites in El-Dakhla Oasis. The values of equilibrium activity ratio of potassium (ARko) ranged between 0.0071 (soil 3) to 0.0320 (mol/L)1/2(sample no. 1). The labile K (-ΔK0) values also, varied from 0.020 (sample no. 4) to 0.412 (cmol/kg soil (sample no.1).The values of the potassium potential buffering capacity (PBCK) of soil ranged from 0.964 to 12.86 [(Cmol kg-1/(mol L-1)0.5]. Generally, the highest value of ARko, ΔK0, PBCK parameters were related in soil sample no. 1[(0.032 (mol/l)0.5, 0.412 cmol/kg, and 12.86 [(cmol kg-1/(mol L-1)0.5], respectively. The ARko was a negatively significant correlated with exchangeable potassium (r=-0.822), Organic matter (-0.633) and available K (-0.444). A positive highly significant correlation was obtained between the labile K (-ΔK0)and both exchangeable Ca and Mg (r=0.936 and 0.941, respectively). The PBCK showed a positive significant correlation with clay content, available K and cation exchangeable capacity (CEC), and negative significant correlations with soil pH (r=-0.795) and CaCO3 (r=-0.633).

Influence of Organic Wastes on Evaporation and Hydraulic Properties of Sandy Soil
A laboratory experiments were conducted to examine the influence of various organic wastes on evaporation and some of hydro-physical properties of sandy soil collected from Al-Bustan region, Egypt. Five treatments: control, 1% of wheat straw, % clover straw, mixture of wheat & clover, and chicken manure on the basis of air dry weight of sandy soil (0.529 kg/m2) were applied directly on soil surface. The same treatments were done with incorporation of organic wastes. Also, plastic mulch used in the two cases of applications as a tool for maximizing the role of organic wastes for reducing evaporation from surface layer of sandy soil. Soil samples were subjected to wet and dry cycles (1st experiment). In 2nd experiment was conducted to evaluate the role of organic wastes for improving the hydraulic properties of sandy soil. The average values of evaporation reduction percentages in case of addition organic wastes on surface of sandy soil, were 22%, 10.4%, 9.8% and 40%, 21.7%, 16.6% in chicken manure and clover straw(CS) treatments along wet and dry cycles in the first, second and third runs (2, 4 and 6 days intervals), respectively. The average values of evaporation reduction percentages, in case of incorporation organic wastes with sandy soil, were 21.3% and 31.7% in chicken manure and mixture of wheat and clover straw (WS+CS) treatments in the first run (2days intervals), respectively while it were (4.9%, 12.4%) and (1.1%, 5.4%) in chicken manure and (WS+CS) treatments in the second and third runs (4 and 6 days intervals), respectively. Using plastic mulch with surface application of organic wastes treatments (SAOWT) on sandy soil reduced the average daily evaporation rate by 21.54% to 35.97% while it reduced by1% to 15.6% in incorporated organic wastes treatments (IOWT) compared to control treatment. Linear equations with high R2 are given to describe and quantify the relationship between evaporation rate and time in all cases of using plastic mulch.Organic wastes led to decrease the values of hydraulic conductivity in sandy soil. Determined values showed that Ksdecreased to 51%, 33% and 16.5%, respectively in WS+CS, CS and WS treatments compared to control.Ks (t) for all treatments were fitted to 2nd order polynomial equation with high R2. Basic infiltration rate values decreased substantially by about 33% in incorporated broad bean straw and chicken manure while it were decreased by about 78% and 50% in case of wheat and clover straw compared to control treatment, respectively. There was a lag time in wet front advance between organic wastes treatments and control treatment. The lag time was ranged between 20 and 7 minutes for clover straw and wheat straw treatments, respectively. Distribution of water content with depth of soil columns appeared the polynomial trend with high values of R2. Incorporated sandy soil columns with clover straw and chicken manure increased the percentage of water holding capacity 20.1 and 15.2%, respectively compared to control treatment. There were highly significant differences between most of treatments.

Geospatial Analysis of Soil Characteristics and Sensitivity to Desertification of Some Alluvial Deposits, El Behira Governorate, Egypt
Geostatistical analysis was carried out to map the spatial distribution of the soil characteristics in GIS environment. The present study aimed to use quantitative method to assess land sensitivity to desertification and produce maps for the study area through coupling geostatistical analysis and Geographic Information System (GIS) for some Alluvial deposits, Kafr El Dawar District, West Delta, Egypt. The study area is located between 31o 00\ and 31o 14\ N and 29o 56\ and 30o 14\ E with total area of 36370.9 ha. The agricultural land covers about 30953.1 ha., and the urban area occupy about 5417.8 ha. To categorize soil properties, eighty five surface soil samples were collected, and soil samples were prepared and analyzed for chemical and physical characterization. The results of spatial variability and dependence indicated that the best fitted semi-variogram models were the gaussian model for soil salinity and soil depth, and the spherical model for sodium adsorption ratio and clay content. The Environmental Sensitivity Area Index (ESAI) was calculated using the overlaying technique of the different quality indices maps, which allow identifying the links between those indices and their spatial patterns. ESA analysis showed that 3.24% of the study area was critical to desertification, 3.12% was fragile to desertification, where most of the study area (92.72%) was Non-affected to desertification. The low quality classes of the ESAI were located at the southwestern part of the study area. The results elucidate that the distribution of ESAI matches the distribution of soil characteristics which were used to calculate the soil quality index. Moreover, irrigation water quality, and management dramatically impact desertification processes. Finally, the study recommended that: i) choosing the suitable spatial and temporal scales, as well as identifying the appropriate parameters, and using appropriate models are essential for correctly identifying and monitoring the ecosystem over long periods of time, to assess the sensitivity to desertification; ii) the assessment of environmental sensitive areas to desertification by coupling geostatistical analysis with modeling in geographic information system is a tool to use by decision-makers involved in the planning of sustainable land uses to identify and resist the desertification hazards.

Investigation of Copper Removal from Aqueous Solution by Cement Kiln Dust as Industrial By-Product
This study investigated the copper (Cu+2) removal from aqueous solution by cement kiln dust (CKD) as industrial by-product in cement manufacturing process. CKD was identified by Fourier transform infrared (FTIR), scanning electron microscopy (SEM) and surface areas show the differences of physicochemical properties. Batch equilibrium experiments were carried out at 20, 25 and 30 oC with time intervals extended to 96 h to investigate the efficiency of the CKD in the removal of Cu+2. CKD expressed high affinity for removal of Cu+2 and was not affected by temperature or time. The removal of Cu+2 was indicated by changes of FTIR and SEM images before and after sorption experiments. The kinetic data were evaluated by fractional power, Elovich, pseudo-first order and pseudo-second-order kinetic models. The kinetic studies demonstrated that rate of the removal followed pseudo-second-order kinetic model (r2=0.99). Thermodynamic parameters, the change of free energy (ΔG◦), enthalpy (ΔH◦) and entropy (ΔS◦) were calculated for predicting the nature of adsorption. The parameters showed that the process was feasible, spontaneous and exothermic under experiment conditions. Solubility equilibrium for various expected copper compounds was estimated and the solubility of copper in Cu-CKD system suggested to be controlled by Cu CO3 precipitation under experiment condition. The results indicated that CKD can be used as a low cost and effective sorbent for copper ions from aqueous solutions.

4- Farm price for the two crops of the study has taken a significant growing trend at a significant level
0.01 by 16.6 pounds / ton, 24.8 pounds / ton, with an annual growth rate of about 7.2% 0.7%, respectively, during the study period. As it turns out that both the wholesale and retail price for the two crops of study has taken an increasingly significant trend at a significant level of 0.01.
5- By studying the relationship between the production cost per feddan from the crop of dry beanas an independent variable and the farm price farm of tone as a dependent variable show that the relative change rate between the production cost per ton and the price farm attained about 0.796. This means that when the production cost of ton changes in 10% leads to changing in the farm price by 7.9 % as this was proven at a significant level of 0.01 during the study period. As it turns out that in studying the relationship between the production cost for ton of lentil and the average farm price The relative change rate attained about 0.691 and this means that when the production cost for changes in 10% leads to a farm price change by 6.9%, as it was proven significantly.
6- The study recommends preparing an integrated study in the field of legume crops to find out appropriate methods that help to reduce the cost of local resources to rise the comparative advantage of the two crops of study, specially they are from the important food commodities, which depends which the consumer relies on them daily.
This research mainly aims at studying the impacts of changing the production factors on the economics of the two crops the dry beans and lentil.And the findings show that:
1- Production costs for both the dry bean and lentils have taken a significantly increasing trend at a significant level 0.01by 109.2, 107, pounds /feddan with an average growth rate of annual increase of about 7.9%, 7.5% over the Period (1996-2014), respectively.
2- Average of the farm labor cost for the dry bean crop attained about 288 pounds / feddan in 1996 rose to about 973 pounds / acre in 2014 in growth rate represents 238.8% from its counterpart in 1996, and represents about 71.4%, 48.3% from the total variable costs in 1996, 2014 respectively, distributed to workers, animals and machines. As average cost of the farm labor for lentil crop attained about 228.5pounds / feddan in 1996, it increased to about 995 pounds / acre in 2014, up represent approximately 335.4% during the study period, and represent about 58.7%, 51.4% from the total variable costs in 1996, 2014 respectively.

This research aims to identify the existence of some professional condition in the internet, to identify the exposure of the researched youth to the internet, to identify how the internet manipulate some social cases (the elections– the political parties– illegal immigration
– illegal marriage– cancellation of subsidy privatization) from the youth’s point of view, to identify the researched youth’s attitude towards some social cases, also, to identify the youth’s attitude towards these cases according their residence (urban – rural) and finally to determine the relationship between the internet manipulation of some researched social cases and the researched youth’s attitude towards these cases.
To achieve these objectives, a classified sample has been chosen, about 15% of the total students in the final year in the faculties of Home Economics and Shariaia and Low (representing Al-Azhar university) and faculties of Engineering and Arts (representing Tanta
University) with a total of 600 students who were chosen randomly.
The dates were collected though personal interviews using a questionnaire from designed, evaluated, tested and prepared at its final shape for this purpose. Frequencies, percentage, mathematical means, standard deviation, simple correlative rate, and T-test were all used to describe and analyze the data.
The most important findings were as follows:
1- The majority of the researched youth use the internet (85.8%) mostly using the social networking sites, (89.2%) chatting (85%) researching information
(68%)
2- The researched youth think that the professional conditions are existed in the internet with moderate or high degree (immediacy – objectivity – credibility) (80.2%) (72.2%) (70.5%) respectively. The first element concerning immediacy was
transmitting the events immediately when they take place, and concerning objectivity avoiding using the pronoun I and allowing the public to express their opinions without criticizing others; as for credibility, showing the events without changing or committing was the most important element.
1- Concerning the internet’s manipulation of some social cases, the result showed:
A- Political cases:
The majority of researched students see that the internet manipulates the cases of elections and political parties with moderate or high degree (80.2%), (82.3%) respectively. The first thing manipulated in the internet about elections is the time of obtaining an election card, while the objective criteria to choose the suitable candidate was the most prominent manipulated in the internet concerning the political parties.
B- Social cases:
The majority of researched students see that the internet manipulates theCase of illegal immigration an illegal marriage with high degree (97.7%),(87.4%) respectively, and all the issues related to illegal immigration aremanipulated with high degree except for one issue, while the illegal marriage’s most prominent issues were the showing of real experiences and real models of the total result some illegal marriages.
C- Economic cases:
The researched youth see that the internet manipulates the case of cancellation of subsidy and privatization with high degree (71.7 – 57.3%) respectively, the most prominent issue concerning the cancellation of the subsidy was the sectors of the
subsidy (electricity – gas – etc), while the conception of privatization was the most important issue concerning privatization.
2- concerning the youth’s researched attitude towards the social cases the study shows that the attitude level towards the case of election and political parties was moderate (84.7 – 55.7%) respectively; the attitude level towards, the illegal immigration and illegal secret marriage was low (99.7 – 64.3 %) respectively; It was shown that the majority of the researched youth’s attitude towards the cases of cancelling subsidy and privation was moderate (88.3
– 80.8%) respectively.
3- There were moral differences between the researched youth concerning the internet manipulating of the cases of cancelling subsidy and privatization for the youth who live in urban areas.
4- There are moral differences in the average attitudes of the researched youth towards the cases of election, political parties, illegal immigration and privatization for the youth who live in rural areas.
There is a proportional correlative and morale relationship at the level (0.01) between the internet manipulation of parties issue and the youth’s attitude towards this case. The study shows also that there is reversed and morale relationship at the level (0.01) between the internet manipulation of the illegal immigration, illegal secret marriages, cancelling subsidy and the youth’s attitude towards these cases. Finally, there was not any relationship at any level between the internet manipulation of the privatization and the youth’s attitude to this case.

This research aims to study the key indicators of Egypt and Sudan cotton exports, by measuring following indicators through 2000-2015:
Market penetration rate index, cotton export instability factor, revealed comparative advantage, relative price of cotton, the geographical distribution of exports and imports of cotton and the relative importance of each country, the annual growth rate for the amount of cotton exports, and market share for the cotton exports of the two countries in their major foreign markets.
The study revealed the following results: Market penetration rate index for Egypt and Sudan cotton exports shows that both countries have a competitive advantage for cotton exports in some countries indicating opportunities for both countries to increase their cotton exports for those markets, by studying the needs and the required cotton specifications of those markets. Calculations of the Revealed comparative advantage showed that the value of the comparative factor during the study period (2000-2015) for Egypt and Sudan each is over one indicating higher comparative advantage in cotton production compared to all competing countries ,this points to the need for work on cotton exports issues in the two countries to maintain this comparative advantage. The study also
revealed that Egypt and Sudan have no competitive price compared to most competitors in the export of cotton in the world market. The study found that there is a low market share for Egyptian and Sudanese cotton in global cotton exports. Coefficient of instability for local production of Egyptian cotton is around 34.5% and for Sudan it is about 43.65%, this high instability ratio is the most influential factor in weakening Egypt and Sudan on cotton export markets. The estimation of the production function indicated that the annual growth rate in the volume of cotton exports from Egypt and Sudan, each separately, is negative indicating deterioration in cotton exports of both during the study period. The study of the market shares of Egypt and Sudan cotton in different markets during the period (2000-2015) showed that the United States, India, Switzerland, Slovenia, Italy and Pakistan are the biggest importers of Egyptian cotton with a market share of more than 3%, while in other countries Egypt share is less than 3% of their total cotton imports. As for Sudan cotton, it was found that markets of Egypt, Bangladesh, Germany, India, and Italy are the largest importing markets for Sudanese cotton, where the market share is more than 2.5%. While in other importing countries Sudan cotton, the market share is less than 1% of their total cotton imports.

The research aims to evaluate the food patterns of two samples in Alexandria and Qena, and its relation to chest disease risks due to air pollution.
A random systematic sample consisted of 400 families have been taken from Alexandria (Wadi Elkamar district at Alexandria governorate), and Hiw at Naja Hammadi – Qena governorate.
The required data was collected by using an especially design questionnaire, which has four parts include demographic characteristics of the family members, food consumption patterns, the sources of indoors and outdoors air pollution as independent variables, and the prevalence of chest diseases among the family members as a dependent variable.
The results show that (47%) of the studied families have patients with chest diseases caused by air pollution, (38%) from Alexandria, while (9%) from Qena. One fourth of patients (25%) are children under 16 years old. The incidence in females is higher in Qena (60%) in comparison to (47.6%) in Alexandria. The
severity of the disease ranged between moderate and severe in Alexandria while in Qena was moderate. The smokers in the families consists (51.5%) and (40%) in Alexandria and Qena respectively.
The results reveal that (62%) of families need to modify their food patterns, only (27%) have a healthy food patterns, represents (37%) of Qena sample and (18%) of Alexandria sample.
Statistical analysis illustrate a significant negative relation was found between having healthy food patterns (such as eating fruits and whole wheat bread daily, marine fish at least once weekly and drinking daily herbal drinks) and prevalence of chest diseases. Significant positive relation was observed between unhealthy food patterns (more saturated fat and salt) and chest diseases prevalence. Healthy food patterns helps in decrease the prevalence of chest diseases by (17.1%).
