A STUDY ON THE PREPARATION AND ADSORPTION PROPERTIES OF ACTIVE CARBON FROM PEACH KERNEL
Peach Kernel (PK) is considered one from many agricultural wastes that represents negative impact on the environment. This work describes a method for the preparation of activated carbon from PK, converting its negative impact on the environment, to positive to be used for removal of contamination. The activated carbon (AC) was prepared in two separate steps of carbonization and activation at 550 & 600 oC. The physical activation was performed by water vapor. The mechanism of adsorption varies from physical and chemical adsorptions. The Fruendlich and Langmuir equations were determined. The yields of produced AC for PK samples were 36.82 % and 15.30 % at 550 oC and 650 oC respectively. Tests were made on prepared AC activated at 650 oC. The percentage moisture content varied from 2.94 – 3.72 %. The percentage volatile matter content varied from 42.51- 61.93 % for PK powder and granules respectively. The percentage ash content varied from 0.49 to 2.41%. The apparent density varied from 0.508 to 0.565 g/cm3. The pores volumes varied from 0.525 – 0.573 cm3/cm3. The iodine numbers for non-activated PK carbon samples were 254.80 - 344.90 for granules and powder respectively. The iodine numbers for activated PK carbon samples were 370.16 and 507.60 for granules and powder respectively. The surface areas by multi-point BET were 26.009 and 40.277 m2/g for non-activated and activated PK respectively. The SEM (Scanning Electron Microscope) images of PK AC show irregular spherical shapes with average diameter of (5-16) nm and macro pores with diameters of greater than 50 nm. The adsorption of iodine on PK AC followed both more Langmuir isotherm with R² = 0.9498 (a= 0.3877 & b= 0.3225) than Fruendlich with R² = 0.8419 with (n=1.4428 & k= 1.1951).

ALLELOPATHIC ACTIVITY OF SOME DESERT PLANTS AGAINST PLANT PATHOGENIC BACTERIA AND NEMATODES
The extensive use of chemicals in plant protection has given rise to concerns about pesticide residues in the environment and to the development of pesticide-resistance by any organisms. Allelopathic plants offer better alternative for this purpose due to being cost-saving, eco-friendly, easy to use, efficient and safe. So, the present work was carried out to evaluate the allelopathic effect of three desert plants (Artemisia judaica, Asphodelus microcarpus, Solanum nigrum) on root knot nematode (Meloidogyne incognita) and three gram negative pathogenic bacterial strains (Erwinia carotovora, Xanthomonas campestris and Ralestonia solanacearum) using root exudates and leaf extracts of each plant with different concentrations. Under laboratory conditions, the data indicated that the three plants contain nematicidal compounds; the inhibitory effect was proportional to the concentrations used. Artemisia judaica extract showed the highest level (100%) of nematicidal activity and indicated good antibacterial activities against all the tested bacterial strains also recorded the best result of minimum inhibitory concentration followed by A.microcarpus root exudate. While the root exudate of A.judaica, S. nigrum had no antibacterial activity, leaf extracts of S. nigrum had weak antibacterial activity. Aqueous leaf extracts of A.judaica appears to be attractive for the development of nematicidal and bactericidal bio- pesticides.

EFFECT OF TWO ALGAE; CYSTOSEIRA BARBATA AND DICTYOTA DICHOTOMA ON DIGESTIVE GLAND OF BIOMPHALARIA ALEXANDRINA SNAILS.
Schistosomiasis ranks the second amongst parasitic diseases affecting human. To reduce the incidence of this disease, several strategies were applied including snail control. Chemical control methods have many drawbacks, hence biological control became the concern of many studies. In this study, eight algal species were tested against Biomphalaria alexandrina snails; the intermediate host of Schistosoma mansoni. The bioassay tests revealed that Cystosiera barbata and Dictyota dichotoma were the most effective species, where the LC50 values were 2200 ppm and 560 ppm consequently. Prolonged exposure to LC25 (280 ppm) of D. dichotoma resulted in death of snails after two weeks. In addition, alterations in digestive glands of treated snails with LC5 (220 ppm) and LC25 (280 ppm) of C. barbata and D. dichotoma, respectively were obvious, as vacuolation of digestive cells were recorded after exposure of snails to LC5 of C. barbata. Moreover, exposure of snails to LC25 of D. dichotoma resulted in noticeable vacuolation of digestive cells and degenerated secretory cells; the lumen was nearly disappeared. The maximum elevations in the activities of both aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were observed after 2 weeks of exposure to LC5 (56 ppm) and LC15 (660.7 ppm) of D. dichotoma and C. barbata, respectively. The total protein contents of treated B. alexandrina snails were significantly different from that of control group after 2 weeks of exposure to different concentrations of both effective algae.
Testing the sublethal concentrations of both effective algae on the Daphnia pulex showed that LC5 (220 ppm) of C. barbata and LC15 (168 ppm), LC25 (280 ppm) of D. dichotoma were the least harmful to these crustaceans.

ACARICIDAL ACTIVITIES OF GARLIC OIL (ALLIUM SATIVUM) AND ITS EFFECTS ON PROTEASE AND ACETYLCHOLINESTERASE (AChE) ACTIVITIES IN RED SPIDER (TETRANYCHUS URTICAE)
Red spider (Tetranychus urtica) is one of many plant species feeding mites, which cause large agricultural losses. Garlic oil was investigated as acaricidal source to evaluate its ability to protect plants from mite injury. The red spiders were spread on green bean seedlings for one week then the plants were sprayed with different concentrations of garlic oil (50,250,1000,2000,5000 ppm). The results showed that garlic oil showed an acaricidal activity against red spider in dose and time dependent manner. Also, high and low concentrations of garlic oil inhibit acetyl cholinesterase (AChE), while protease activity was declined due to treatment with 1000, 2000 and 5000 ppm garlic oil. On the other hand, the concentration of 50 and 250 ppm increase the red spider protease activity. We can conclude that the garlic oil exhibited acaricidal activity against red spider. The observed acaricidal effect of garlic oil is highly correlated with the inhibition of acetyl cholinesterase (AChE) and protease activities.

NANOTECHNOLOGY AS AN APPROACH TO GREEN ARCHITECTURE
The research highlights an extraordinary amount of interest in nanotechnologies and nanomaterials، terms now familiar not only to scientists، engineers، architects، and product designers but also to the general public. Nanomaterials and nanotechnologies have been developed as a consequence of truly significant recent advances in the material science community. Their use، in turn، is expected to have enormous consequences on the design and engineering of everything. Hopes exist for being able to make things smaller، lighter، or work better than is possible with conventional materials. In the sustainability and energy generation domain، for example، nano-based fuel cells or photovoltaics can potentially offer greater efficiencies than are possible with conventional materials.

THE SOCIAL AND PHYSICAL VARIABLES ASSOCIATED WITH TAKING VENGEANCE CRIME A CASE STUDY ON A VILLAGE IN UPPER EGYPT
Vengeance crime considers one of the most dangerous social crimes in human societies. It is an old crime since man ever has existed on earth. It is the first enemy threatening societies and nations’ stability, safety, development and progress. This study objective is to identify the relationship between social and physical variables and crime of taking revenge. In order to study this issue, the researcher has designed an interview guideline for collecting data, examining, and diagnosing the study cases (n=20) items. The form includes some demographic data including (age-sex-qualification-social status-career-number of children-residency place-average income-agrarian property size) in addition to data concerning the family of researched items, using technology, cultural communication, reasons for vengeance crimes and data of resolving problem. The researcher uses the qualitative-analytical method and the case study method. The study results indicate that there are some social variables (age - certificate - social status-dependency- income - order of children – family position – degree of kinship) connect to taking revenge crime, as all examined cases show respect to norms, traditions, and societal customs as a natural submission to public opinion and tribal Sovereignty of the group. The study results indicate that there are some (physical variables) associate with taking revenge crime such as (original residence – work location – cultural communication – available technology – residency locate – perfection of language – quality of work – communicating with foreigners – experiences of travelling abroad). And crime of taking revenge in Upper Egypt. The study recommends the necessity for setting the Upper Egypt on the plan list of development, establishing as well separate juridical panels that would be responsible for taking vengeance causes in Upper Egypt and consist of customary and formal judges.

SOCIAL AND PHYSICAL ENVIRONMENT VARIABLES ASSOCIATED WITH BUILDING ON AGRICULTURAL LAND A FIELD STUDY ON SOME VILLAGES IN AL-DAQAHLYIA GOVERNORATE
The study aims to recognize the variables of the social and physical environment associated with the inconsistent building on the agricultural land, which happening to the Egyptian village, determining the reasons that make the farmer have an inconsistent building on the agricultural land; moreover, the study aims to recognize the effects resulting because of the inconsistent building on the agricultural land. In order to achieve the goals of the study the researchers have organized the study in two chapters: the first deals with the reference and theoretical study of the most previous studies, on the other hand the second one deals with the field procedures and studies and the study of the local society of some villages in Dakahlia governrate.
In order to achieve the goals, the researcher has divided the society into three sectors: (north, middle and south) so that the sample can be greatly resembling to the society, this study depended on the descriptive and social survey curriculum and the curriculum of the local society study, in addition to that this study has appealed for some tools to get some field information including: (the questionnaire form, the deep encounter/meeting and the study of the local society index). The researcher has appealed for a 153 sample of the ones who have built inconsistently on the agricultural land of 3060 total contradicting with the society of the study(some villages of Dakahlia governrate) representing 5% of the contravener and the number of the villages connecting with the study.
The results of the study:
1) There is a relation among the social changes(the living independence desire, education standard, income standard, and family standard) the most common on the study field and the inconsistent building on the agricultural land, resulting in 41.2% of the people who have less than an acre who have built inconsistently on the agricultural land; moreover, there are some who don't own a land at all representing 32.7% have also built inconsistently on the agricultural land, which means that ownership is not a condition not to stop or the inconsistent building on the agricultural land.
2) There is no relation between the physical environment changes and the inconsistent building on the agricultural land, despite the increase of the acre production, constructing on the agricultural land is increasing gradually.
3) There is no statistics including (males, females) in the family and the inconsistent building on the agricultural land.
4) There is dominance of 73.9% of the nuclear family in the villages of Dakahlia governrate, on the other hand 17.6% of the extended family matching with many previous studies.
5) There is no statistics including the number of the children (male, female) of the family and the inconsistent building on the agricultural land.
There are no differences of a statistic reference (0.01) between the rural society and the civilized rural one according to the type and the style of the inconsistent building on the agricultural land.
6) The study recommends that there has to be a serious intervention from the country to find unconventional solutions limiting the inconsistent building on agricultural land, otherwise Egypt is going to suffer from extreme desertification of its agricultural lands that is going to affect badly on the national income throughout the agricultural sector that represents the main income for Egypt as it is considered to be an agricultural country.

This study drives at developing curriculum of French language for primary grade-four using strategy of modeling and simulation for developing skills environmental of those students. In order to achieve that purpose, a checklist of the most important topics and environmental problems has been designed, that should be included within the French curriculum. A content analysis is used in terms of topics of (air pollution – the black cloud – non-renewal resources depletion – oil depletion – water pollution – water scarcity). A scale of Skills environmental is designed and a conception of proposed two units in French is suggested, selecting unit four and six for application. These units are taught in (street – garden) containing some environmental issues and problems and using modeling and simulation strategy. The study uses the quasi-experimental method to try the two units, using as well the descriptive method to analyze the objectives and content of the curriculum of both units. Results indicate significant statistical differences exist between average scores of the experimental and the control group regarding the post-application of scale environmental skill, in favor of the experimental group. The study suggests applying those proposed two units and the scale on other various educational stages since they have proved their efficacy.

THE DEVELOPMENT OF HUMAN RESOURCES AND THEIR ROLE IN ACHIEVING SUSTAINABLE DEVELOPMENT SPECIAL STUDY ON EDUCATION SECTOR IN BANY WALID – LIBYA
The sustainable development process is a process includes human development for the purpose of improving level of health care and education in addition to participation in of people in developmental decision-making that affect their lives; added to that the element of justice, fairness, and equality. There are two types of fairness. Fairness to the coming generations and fairness towards those who are living at present and have needs and suffer from inequality in obtaining natural resources or social services. Sustainable development also drives at promoting opportunities of education and health care.
The concern in the connection between human development and concept of sustainable development is evidently increasing, as there is a critical need for making balance between population on one hand and the available resources on the other hand, it is a relationship between present and future to guarantee a better life for coming generations. That is why the environment issues should everlasting be associated to development as there is no sustainable development without human development.
This study discusses the great role the development of human resources play to achieve sustainable development, since human resources are the factor determining targets and policies, it is also the factor sets plans and programs and bear the responsibility of directing and utilizing the optimal use of potentials and available concrete resources. So, the investment in human resources is achieved through education which is an important and fundamental part of building up human potentialities and skills effectively. Education represents a basic resource for all developmental plans and a basic pillar of sustainable development.
The researcher follows the descriptive method in analysis by collecting data, information, and statistics due to sex (male/female), educational certificate (university certificate – post graduate – above middle – middle – less), and age stage (21-31, – 30-40, 41-51, 50-60). The study sample consist of (100) items. It also uses the statistical method.
The study results indicate that there exists shortness in the scientific research system regarding plans, programs, approaches, and methods that are based on science and cope with economic changes and global challenges. There is a direct positive relationship between building education programs and plans and efficiency of human resources management policies.
The study recommends considering education, training, scientific research and technological development as the most important means for achieving policies of human resources development; recommending also raising the competitiveness of performance in order to achieve demands of growth, developing as well the educational curricula, training, and the scientific research to be connected to policies of human resources development.

A PROPOSED FRAME TO IMPROVE ALTERNATIVE INVESTMENT OPPORTUNITIES OF SOCIAL INSURANCE FUNDS FOR ACHIEVING ECONOMIC AND SOCIAL GROWTH
This study problem is crystallized in that resources of social insurance cannot achieve its targets or determinants which require reconsidering of the style of investment in a way that guarantees non-losing of political investment decisions. Achieving actual independency for insurance system should be available in order to fulfill its objectives.
The study drives at examining how the elevation of profits of social insurance resources investment for the purpose of elevating level of pension beneficiaries and magnifying the economic benefit in the state through alternative investment opportunities.
Funds of the social insurance could be considered as an Independent variable, while the uses of the social insurance funds in the process of the socio-economic development is a balanced variables of the Intermediate variables, while the independent variable is presented in improving the alternative investment opportunities for the funds of the social insurance.
Among the most important tools used in the study are social insurance reports (the governmental and private sector) as well as the annual report of the Central Bank during the period from 2000 to 2012. The study found that investment in hypotheses mortgage and securitized is one of the most suitable investment fields of the resources of social insurance.
