 The main objective of the research is to examine the rote of corporate environmental disclosure in
 aiding investment decisions and to study the possibility of developing this disclosure to account for
 the environmental effects of corporate economic activity, with the purpose of satisfying the
 information needs of investment decision makers and supporting the decision making process
 within the Egyptian Market Community. An empirical study was carried out aiming at (a)
 examining corporate environmental disclosures made by Egyptian companies operating in
 environmentally sensitive industries, through content analysis, and (b) investigating the importance
 and use of such corporate environmental disclosures in making investment decisions and
 discovering what sort of environmental information needs Egyptian investors demand, through
 survey analysis using a questionnaire. Results indicated that although there is a general increase in
 the level of corporate environmental disclosure, relatively little detailed and incomplete
 environmental information is provided in the annual report. The most important conclusions
 reached include the insufficiency of corporate environmental disclosure for investment decision
 making purposes, the great importance of such disclosure for investors and its significant effect on
 their investment behavior. In addition corporate environmental disclosure was found to be
 positively correlated to firm-related factors, face several obstacles, and hence need a variety of
 supporting means for development.

 The present work introduces fabrication of alumina from aluminum dross tailings to use it as a
 desiccant in the air conditioning applications of evaporative cooling to extend its use. The
 thermophysical and adsorption characteristics of the produced alumina had been evaluated and
 was not satisfactory for low relative humidities. This was treated by adding zeolite by 20% weight
 of mixture and use it as a good desiccant under the name of aluminaz. The factors affecting both
 the air dehumidification and regeneration process for aluminaz were performed. Mathematical
 model of the combined heat and mass transfer during the air dehumidification and regeneration
 process were developed. A case study to cool an industrial space was done as well as a desiccant air
 conditioning system was also analyzed numerically and its performance at full load and part load
 was discussed.

 The research aims to the Identification of the Effect of Administration vitamin C and Allopurinol
 on the formation of free Radicals and recovery at some of the middle and short distance running
 competitors from through measuring some blood variables. The measurements included muscles
 exhausting indicators like (lactic Acid and Xanthine oxidase) oxidation pressures indicators like
 (Nitric oxide and thiobarbit-uric-Acid reactive substances) and antioxidant indicators like (total
 Antioxidant) Glucose, creatine phosphokinase and uric Acid were also measured in order to relate
 oxidation indicators to exhausting and recovery, the researcher used the experimental method
 because of its suitability for the nature of the study and the research sample has been choose on
 purpose from running competitors who are registered in Assiut region of athletics. The sample
 consisted of ten competitors divided as follows: Five competitors of 100 m race. Five competitors of
 800 m race. Conclusions: Taking vitamin C Before the 100 m race leads. The reduce of: Xanthine
 oxidase. Taking allopurinol before the 100 m race leads to reduce of: Thiobarbit uric acid reactive
 substances, Xanthine oxidase, lactic acid, total Antioxidant, uric acid and the researcher.
 Recommends with: Taking care of organizing sports practice so that a player would not reach the
 over load phase which causes free radicals. Taking care of having vitamin C and Allopurinol as one
 of the antioxidants as it is a good fighter of free radicals and oxidation besides it plays an important
 role in quick recovery.

 This experiment was carried out during three successive seasons of 2001, 2002 and 2003 on Balady
 mandarin cultivar. The trees were sprayed at full bloom with gibberellic acid (GA3) at 5, 10 and 20
 ppm, in addition to the control trees. The results indicated that the number of fruits/tree and the
 total yield (kg) increased with GA3 treatments comparing to the control. Data also indicated that all
 the treatments caused high significant increase of commercial fruits comparing to the control. The
 fruit weight increased as a result of GA3 application. Pulp weight greatly increased meanwhile peel
 weight slightly increased as a result of GA3 treatments. Juice volume significantly increased by
 increasing GA3 concentration. Total soluble solids percentage slightly decreased and the total
 acidity percentage increased in the treated trees. Subsequently, TSS/acid ratio decreased as a result
 of GA3 treatments. The results also indicated that all GA3 treatments greatly decreased the number
 of seeds/fruit. GA3 applications increased leaf length and width. Such increase was more
 pronounced in spring growth cycle than summer one. Generally, there were no significant
 differences between 10 and 20 ppm GA3 concentrations in most studied characteristics.

 The aim of this study was to identify impact of breast feeding duration infant, and child growth 2
 years of age. Inclusion criteria all infants and children aged 6-24 breast feeding since delivery. The
 study cases all infant and child breast feeding or stopped breast feeding. The study included 151
 infants and their mother's. The means of length, weight head circumference and chest
 circumference was significantly higher among cases receiving exclusive breast milk for 4 month or
 more than cases receiving exclusive breast feeding less than 4 month. It was found that body length
 was significantly higher among breast feeding in the age group 18-24 month than length of non
 breast feeding infant in the same of age group. It was found that skin fold thickness was
 significantly higher among breast feeding infants in the age group 6-12 month than skin fold
 thickness of non breast feeding in the same of age group. The study recommended that mothers
 should start breast-feed immediately after birth or at most within half-an hour of delivery and then
 on-demand and not according to a timetable. Promotion of exclusive breast feeding in the first 4-6
 months of life. Continue to breast feed for up to two years and beyond avoid using bottles,
 pacifiers, dummies or other artificial nipples.

 Breastfeeding is the incomparable first food for a newborn infant In the first two years of life,
 feeding patterns play a fundamental role in the infant's growth and health. Differences in patterns
 of breast feeding exist within and between countries and cultures. This cross-sectional study was
 done to profile breast feeding pattern in El-Boora village, Assiut district. It included 300 infants
 and young children less than 24 months of age. Their mothers were asked about infant feeding
 practices, including breast feeding and complementary feeding patterns. Only 35.7% of the sample
 was put to the breast within an hour after delivery, but the majority (84%) began breast feeding
 within the first day. Colostrum was the first food given to 71.7% of the sample. The prevalence of
 breast feeding was found to be 80.3%. Only a minority of infants were exclusively breastfed
 throughout the first 6 months of life. Exclusive breast feeding rate at 4 months of age was 7.9% and
 decreased to 4.4% at six months. The majority of infants were given liquids mainly plain water. So,
 full breast feeding was found to be 60.5% at 4 months of age and 51.5% six months. Timely
 complementary feeding rate was 76.2%. Continued breast feeding rate (1 year) was found to be
 83.8%, while continued breast feeding rate (2 years) was 38.7%. Insufficient milk was the main
 reason given by mothers for termination of breast feeding (44.1%). Most mothers accept breast
 feeding as the best for the infant, but more emphasis need to be placed on encouraging early
 initiation of breast feeding within the first hour after delivery. A major problem is that the great
 majority of mothers don't breast feed exclusively in the first six months of the infant's life. So,
 exclusive breast feeding rate is very low and an intervention is highly recommended to increase it.
 These problems can be effectively countered by appropriate health education, training of health
 workers and effective lactation management.

 Three experiments were carried out at Poultry Experimental Farm, Faculty of Agriculture, Assiut
 University to study the effect of some managerial factors (feed restriction, lighting program, type of
 litter) on broiler performance. Although feed restriction programs resulted in lower body weights
 as compared by ad libitum feeding program, it was economically more efficient than ad libitum
 feeding program and was associated with lower fat product which matches the consumer desire
 and health. The most suitable lighting program for rearing broilers is the increasing lighting
 program, because it was more economically efficient than continuous or intermittent lighting. Also,
 using increasing lighting program was associated with less mortality and leg disorders than
 continuous lighting. Nevertheless, increasing lighting program was associated with less fat
 deposition which results in a more healthy products. Using sand as a litter during rearing broiler
 chicks up to 7 weeks of age, is better for their performance and economic efficiency than either
 wheat straw or saw dust.

 This experiment was designed to trace the value of two plant protein sources, full-fat soybean
 (FFSB) and corn gluten meal (CGM) as a substitutes for soybean meal (SBM) in broiler diets in
 three main trials. A total number of 175 one day old chicks (Arbor acres) were weighed and
 randomly distributed into seven groups of 25 chicks each. A control group in the first trial was fed
 on three diets, the starter, grower and finisher based on SBM as the main protein source. In the
 other two main trials, two vegetable protein sources were tested as soybean meal substitutes, the
 full-fat soybeans and the corn gluten meal. Each of the plant proteins were used at a maximum rate
 of 20% in the broiler diets. For each SBM substitute, three groups were allotted, the first for
 feeding the substitute along the three feeding phases; starting, growing, and finishing; while the
 second for growing- finishing phases and the third for finishing period only. The growth
 performance, body weight development, weight gain, feed intake and feed conversion efficiency
 were assessed. In the first group of full-fat soybeans trial, there was a slight reduction in growth
 rate about 8%, consuming the same amount of food as that of the control (99.4%), and eventually
 slightly low food conversion efficiency. In the second group, more food consumed and less weight
 gained and by turn more lower feed conversion efficiency. In the third group and in which FFSB
 feeding was limited to the finishing period, growth rate was slightly higher than the control, as also
 the feed intake resulting in a feed conversion index nearly equal to that of the control. In trial III,
 feeding of broilers on 20% corn gluten meal during the three feeding phases of growth or during
 growing-finishing periods had adverse effect on the feed intake, body weight, in addition to feed
 utilization compared to control, while only confinement of CGM feeding to the finishing period is
 feasible. There were no differences in the chemical composition of carcass meat and serum total
 protein between different experimental groups in trials II & III and control one. It is concluded
 that substitution of broiler diets with 20% heat processed soybeans during growing-finishing and
 finishing periods support chick performance and efficiency of feed utilization, while corn gluten
 meal could replace 20% of the diets in broilers during the finishing period only.

Governorate which represented by El-Kharga Oasis, El-Dakhla Oasis and El – Farafra Oasis.
Constituted the material of this study. All camels were subjected to careful clinical and laboratory
examination to prove their healthy status in addition to study the most important diseases which
affect camels in this area and their prevalances. According to their age, sex and reproductive status
(early, mid and late pregnancy) camels have been classified. Also diseased camels included camels
suffered from dietetic scour, gastrointestinal parasitic infestation, Trypanosomiasis, Filariasis and
mange mites infestation. The study revealed the most important diseases and their prevalances rate
which affected camels in New Valley Governorate were: Dietetic diarrhea (4.83%).
Gastrointestinal parasitic infestation (33.45%), Trypanosomiasis (6.55%), Filariasis (14.83%),
Manage mites infestation (2.07%) Also the study recorded the most important clinical signs of the
abovementioned diseased camels. Moreover, Filariasis was recorded as a first record in camels
reared in New-Valley Governorate (Egyptian oasis). Haemematological picture including total
erythrocytic count, haemoglobin concentration and packed cell volume have been carried out and
also the reflection of both physiological and diseased conditions upon haemogram picture were
recorded. Estimation of blood serum trace elements including copper (Cu), Iron (Fe), cobalt (Co),
Zinc (Zn), manganese (Mn), Molybdenum (Mo) and Iodine (I) levels in both healthy and diseased
camels were carried out. Statistical analysis of the obtained data were Performed to study the
influence of physiological and diseased status upon both haemogram picture and the levels of the
abovementioned trace elements.

A field experiment was carried out during two successive seasons (summer 2003 and 2004) on two
sorghum cultivars (Shandaweel–2 hybrid and Dorado variety) using surface and drip irrigation
systems under certain levels of nitrogen fertilization (75 100 and 125 kg N/fed); to study their
effects on yield and its components, concentrations of N, P and K and protein content in grains as
well as, evaluation of N recovery, N–use and water use efficiencies. The results indicated the
1-The highest values of panicle length, diameter and weight as well as 1000 – grain weight and
  shelling% of sorghum plants were obtained from Shandaweel 2- hybrid using drip irrigation and
  receiving 125 kg N/fed .
2-The highest grain yield (20.34 ard/fed) was obtained from Shandaweel–2 hybrid that received 125
  kg N/fed under the drip irrigation system.
3-Concentrations of N, P and K as well as protein content of grains were significantly increased
  using drip irrigation system compared to surface irrigation, but nitrogen fertilization, exerted a
  significant influence on all traits.
4-The nitrogen recovery and N use efficiency significantly affected by all interactions under study.
  The highest value of N recovery (58.58 kg N/fed) was obtained from Shandaweel 2- hybrid that
  received the highest N level (125 kg N/fed) under drip irrigation system. The highest value
  (58.18%) of N use efficiency was obtained from Shandaweel 2- hybrid that received the lowest N
  level (75 kg N/fed) under drip irrigation.
5-The water use efficiency was greatly affected by all interactions under study. The highest value
  (2.71 kg grains/m3 water) was obtained from Shandaweel–2 hybrid that received the highest N
  level (125 kg N/fed) under drip irrigation.

This thesis consists of five chapters proceeds by an introduction and ends with a conclusion. First
chapter consists of three parts, a) deals with some essential concepts such as: ecology, ecosystems,
environmental problem, b) shows the general geographical characteristics of Assiut Governorate,
and c) deals with the classification of Assiut Governorate to ecosystems. River Ecosystem and its
problems is the topic of the second chapter, which studies the chemical, biological, and thermal
pollution of the river channel. The disturbance of water budget (causes and effects) of the river
system is one of the vital aims of this chapter. Agriculture ecosystem and its problems are the goal
of the third chapter which concerns with: qualitative and quantitative degradation of the flood
plain soil, occupational diseases (zoonoses) and the general features of new reclamated lands.
Chapter four studies industrial ecosystem by making a distinction between scatter and planned type
(industrial state) in the governorate. the chapter show the environmental problems which are
related to the scatter type, while the student carry out geographical environmental impact
assessments in order to determine advantages and disadvantages of industrial activity of El Ghorieb
industrial area. Urban ecosystem is the issue of the last chapter which studies the essential problems
of each urban and rural ecosystem, such as pollution of drinking water, sewage, air pollution as a
result of heavy traffic. the student carries out two cases of geographical environmental impact
assessments, one to New Assiut city, and the other to one of the alternative villages to those
damaged as a result of 4 November 1994 rainfall (El zawia village). Finally the conclusion tries to
present the final results of the study and recommends some alternatives which may helps to
overcome some environmental problems in Assiut Governorate.

 The effects of Pronifer on the performance of lactating ewes and their offspring were investigated
 in the present study. Twelve single type of birth fat-tailed ewes with their lambs were divided into
 two similar groups according to their lambing date and weight of lamb. Animals were assigned
 randomly to either the control diet (20% wheat straw and 80% concentrate mixture) or the
 experimental diet (the control diet plus Pronifer at a rate of 3 kg/ton of the concentrate mixture).
 The experiment lasted for 10 weeks starting at the 5th day after lambing time. Milk yield as well as
 its fat and protein content were determined in the 3rd, 4th and 5th week of lactation. Weighing lambs
 at birth and biweekly thereafter assessed their growth performance. At the end of experiment,
 blood samples were collected from ewes and lambs to determine some serum metabolites. Results
 indicated that ewes supplemented with Pronifer in their diet tended to produce higher milk yield,
 protein percent and protein yield than untreated ones by 9.3, 4.7 and 14.6%, respectively.
 However, fat percent and its yield tended to be lower by 24.9 and 13.2%, respectively in the tested
 than the control group. Average daily gain of tested lambs was numerically higher (about 12%) as
 compared with control lambs. Concentration of serum glucose and total cholesterol increased
 significantly (P<0.05) in the Pronifer supplemented ewes and their offspring. Albumin
 concentration significantly (P<0.05) decreased while globulin concentration significantly (P<0.05)
 increased in blood serum of Pronifer supplemented animals. It could be concluded from the
 present investigation that the use of the probiotic Pronifer leads to improve the health status and
 feed utilization of both ewes and their lambs.

 The thesis deals with the environmental problems in Kharga Depression, from a geographical of
 view. The thesis is divided into five chapters preceded by an introduction and followed by a
 conclusion. The first chapter deals with the most important environmental features (physical and
 human) for Kharga depression to specify the relation between these features and environmental
 problems. Chapter two is dedicated to the study of the environmental problems with relation to
 climate, the most important are hydrological drought, heat and cold waves, and dust storms. The
 study is made of definition, causes, impacts, and resisting methods.. At the end of every problem,
 the study introduces some suggestions to decrease the impacts of this problems. Chapter three is a
 study of environmental problems with relation to geomorphology and their impacts on the aspects
 of human activities and resisting methods, and every problem ends with introducing some
 suggestions to limit their hazards. A study is made about the Barchan sand dunes movement
 between 9/2001 to 8/2002. The dunes have been shown to be moving between 12.5 m and 96.1 m per
 year. The study is made of mass-wasting movement, The salt weathering, drainage water. In
 addition to the study of surface subsidence. Chapter four deals with environmental problems with
 relation to soil concerning salinization, Induration, waterlogging, pollution and study of
 desertification add to their impacts, and concentrating on pouplation"s resisting methods are also
 displayed. Also some suggestion are displayed to limit the impacts of this problems. Chapter five is
 a study of problems with relation to underground water, the most important problem is the
 variation in underground water level, either by decrease or increase. And the problem the
 underground water pollution chemically, biological and physical pollution. Then their effects on
 human activities in depression. Every problem concludes to reference to the number of methods
 that may be followed to limit their hazards. The conclusion includes the results and
 recommendations of research concerning the methods to resisting problems from which study area
 is suffering and trying to develop agriculturally and industrially. This is followed by indices and the
 bibliography of thesis.

 TITLE           : The Effect Of Iodine And Selenium Supplementation On Thyroid Function
                    And Some Biochemical Indices In Goats At Assiut Governorate.

 This investigation manifested the effect of supplementation of selenium or iodine alone or together
 on some health indices of conventionally grazing premature goats. A total of twenty male Balady
 goats showed poor growth were classified equally into four groups (5 each). Feed stuff of the first
 group was supplemented with selenium (Se), the second was supplemented with iodine (I), the third
 was supplemented with selenium and iodine (Se+I), while the fourth group was not supplemented
 and considered as control group (C). After 45 days experiment the body weight and gain between
 groups was differed. It increased (P<0.05) than the control group, while the Se+I group showed
 significant increase (P>0.05) in body weight gain than Se and I group. The haematological
 parameters (RBC, Hb and PCV) did not differ significantly in Se or I group if compared by the
 control group, but Se+I group showed significantly higher mean values (P<0.05) than control.
 Supplementation with Se had no effect on the mean values of blood serum T3 and T4
 concentrations, while there was significant variations in these parameters in the iodine
 supplemented group than control. The group supplemented with Se+I showed higher values of the
 mean values of blood serum T3 and T4 concentrations than the control, Se and I groups. The results
 showed also that supplementation with Se or iodine alone had no effect on the mean values of blood
 serum total protein, albumin, globulin, cholesterol or AST. However, the supplementation with
 both selenium and iodine resulted in significant increase in the mean values of blood serum total
 protein and globulin. This study clarifies the synergistic effect between selenium and iodine on
 thyroid function and biochemical indices of goats at Assiut Governorate.

TITLE           : The Hydraulic And Hydrochemical Impacts Of The Nile System On The
                   Groundwater In Upper Egypt.

 The Nile system in Upper Egypt includes the River Nile, the irrigation canals and drains nets. The
 Quaternary groundwater aquifer represents the main aquifer in the area. It is essentially
 recharged locally from the Nile system water.
 During the last four decades the water levels in the river were nearly controlled. However, the
 water levels in the main irrigation canals are periodically fluctuated and are more higher than the
 water levels in the Nile River at the same latitudes. They are fluctuating continuously but with
 different amplitudes and manners.
 In the present study a trial has been made to detect the hydraulic and hydrochemical impacts of
 the Nile system on the groundwater in some selected localities in Upper Egypt. The study depends
 mainly on the analysis of the available measured and collected data concerning the surface and
 groundwater levels and composition in the area.
It was concluded that the fluctuations in the groundwater levels are strongly related with the
surface water fluctuations in the main irrigation canals, while the chemical impact of the surface
water on the groundwater is limited.

 The present study deals mainly with the effect of the construction of Aswan High Dam (AHD) on
 the groundwater in the Nile valley, Egypt. The study area occupies the Nile Valley at Qena and
 Sohag in Upper Egypt. Statistical parameters and analysis has been used as a tool to illustrate and
 interpret the aim of study. The groundwater levels, after CHD, have shown relative steady state
 that reflects the existence of direct hydraulic interaction between the aquifer and the River Nile in
 the area of study.
