Studies of the key factors influencing the population dynamics, seasonal distribution, choice of habitat in terms of survival and multiplication of the solitary desert locust Schistocerca gregaria, in particular those factors leading to gregarisation (cause phase transformation) were conducted. The specific objectives include studies on the population densities of desert locust in the summer and winter breeding zones, (correlation between desert locust population and habitat, plant community structure, plant densities and weather conditions), morphometrics of the natural and reared populations, the life cycle and the role of different food plants on development, maturation, fertility, fecundity and longevity of the solitary desert locust under field conditions, and the effect of food plants on the developmental period and survival of the nymphal stages under laboratory conditions. During the period of the study in the summer and winter zones it was found that locust activities were greatly influenced by the amount of the annual rainfall. During the regular survey at the Red Sea coast more numbers of adult solitary desert locust were found in Pennesitum fields and in Heliotropium plants communities, whereas in the summer the survey showed that solitary desert locusts were mainly confined to areas of dense and green annual vegetation of uniform structures, particularly Cenchrus spp., and Indigofera spp., followed by Cyperus spp, and Panicum spp., habitats. It was also observed that at the beginning of the season locusts were not encountered on the seedlings of cultivated Pennesitum in the summer areas and that was mainly attributed to the low vegetation density due the weeding practices in cropped areas, whereas in the winter breeding areas the crop (Pennesitum) was sown in close rows and it was not weeded hence the vegetation density in the cropland was high and it attracted more locusts as compared to the summer areas. This suggests that locusts are attracted to habitats of high vegetation density and compact structure, because they probably need to protect themselves against the unfavourable weather conditions and against the attack of natural enemies; in addition to their need for food. Locusts were clearly noticed in the croplands when the surrounding areas started to dry up and while the Pennesitum plants were still green. During this study it was found that the vast green area to which locust could move and find conditions suitable for breeding, influenced its distribution hence there was less tendency for concentration. In this study and during the field survey at the winter breeding zone it was observed that solitarious females preferred to oviposit in sandy soil characterized by dense and tall Pennesitum plants intercepted with Heliotropium spp., and some other plant species such as Lueanea spp., Fagonia spp., and Cyperus spp. Optimum oviposition, time when the maximum numbers of females were observed laying, ranged between 11.00-13.00 hr., the dry air temperature ranged between 28-33 oC, and the soil temperature at the depth of 15 cm below the soil surface ranged between 22-29 oC. The total number of eggs/pod laid by females of solitary desert locust under field conditions ranged between 100-173 eggs/pod. Rearing of adult solitary desert locusts females in cages under field conditions on certain naturally growing host plants that included Heliotropium undulatum, Aerva javanica, and Pennisetum typhoideum in winter and Heliotropium bacciferum, Pennesitum typhoideum, Frasetia lonquisilia, Cenchurs biflorus, Cyperus conglomeratus, and Tephrosia purpura, in the summer was successful because these plants appeared to provide the nutritional requirements for normal development of solitary locust except for Panicum and Tribulus, which, among other things were found inferior in their nutrient value (nitrogen content). On the other hand females reared on H. undulatum under field conditions showed highest fecundity, fertility and longevity compared to those fed on P. typhoideum and A. javanica. However these food plants when used for rearing the immature stages of solitary desert locust under field and laboratory conditions, in winter, were found to support normal development. During this study it was found that the food quality (high nitrogen content) positively influenced development, maturity, fecundity and longevity of the solitarious desert locust. The average maturation period of the solitary females reared in summer under natural field conditions at a mean temperature of 35 oC was 18.5 days, whereas for those females reared in winter the average maturation period was found to be 25.4 days at a mean temperature of 29 oC. It was also found that some food plants affected the morphometrics of the desert locust. Locusts reared on Aerva javanica showed morphometrics close to those of solitarious individuals, whereas those reared on Heliotropium undulatum and Pennesitum typhoideum showed morphometrics close to those of the gregarious individuals. Morphometric measurements of the samples collected from the natural population in summer (2000) indicated that the population was solitarious and populations of the desert locust found in winter (2000-01), in summer (2001), and in winter (2001-02) in Tokar delta were classified as transient. During years of good rainfall in winter and in summer, three generations could be produced; two generations in winter and one in summer.

La technologie d’agent mobile est une technologie prometteuse pour les systèmes distribués grâce aux différents avantages et qualités qu’elle apporte. Dans notre travail, nous nous intéressons à intégrer le modèle d’agents mobiles dans les environnements intelligents particulièrement dans les soins de santé. Nous proposons deux modèles de service à base d’agents mobiles, pour ambulance intelligente, pour la transmission des données en temps quasi-réel, offrant ainsi plus de flexibilité et d’efficacité pour le service médical. Nous nous focalisons, ensuite, sur l’aspect sécurité des systèmes à agents mobiles, nous proposons deux mécanismes de sécurité : la trace cryptographique pour assurer l’intégrité de l’agent mobile et l’authentification de son origine, le mécanisme d’agent SOS pour assurer la protection de l’agent léger lors de sa migration contre les hôtes malveillants et aussi contre les attaques de déni de service (DOS). Par ailleurs, nous menons une étude sur l’association de la technologie d’agent mobile avec l’internet des objets (IoT) dans les soins de santé intelligents. Ensuite, nous présentons une amélioration d’une architecture existante de soins de santé intelligents typique en intégrant les agents mobiles afin d’assurer la confidentialité des données transmises à travers le réseau et la disponibilité du système.

This Study is a descriptive and exploratory study as it seeks to evaluate and identify the weaknesses of current HRM system in Birzeit University and to identify the main core competencies needed to serve as a base for a competency-based HR management system, including all Birzeit University HRD functions. In order to reach these objectives, focus group, semi structured interviews and survey. Focus group was moderated by a professional and neutral moderator, whereas interviews were carried out personally in order to clarify some points and validate results from focus groups.The findings of this study indicates that Birzeit University suffers from deficiencies in the four main HR functions,and this due to the absence of integrity between these functions and using a job description-based HRM system. There is a gap between what is mentioned in HUD’s mission and its vision statements and what actually is provided to employees which causes frustration from the current system. I’ve concluded that current system doesn’t support the University's vision, mission and culture; BZU also has no strategic plan since 2008. HRD is not included in the top level decision-making nor plays a strategic role.This study tried to find solutions for earlier mentioned deficiencies and to develop and adopt a system which can support the integration of the main four human resource functions, improve job satisfaction and employee retention, change the role of the HR to a new role as a strategic business unit. This study identified the main core competencies needed to adopt this system, practical implications of the competency-based system, and recommendations which serve as a road map for implementing a competency-based HR management system in BZU.

Un savon est en général un sel de sodium comportant une longue chaîne d'acides gras.Sa formule générale est RCOO-Na+ où R est une chaîne d'hydrocarbures CH3(CH2)10-16.On le fabrique le plus souvent par une réaction de saponification qui fait intervenir un ester(RCOOR') et une base (souvent NaOH).Dans le domaine de la savonnerie, il existe de nombreuses variétés de savon trèsDifférentes les unes des autres. Nous pouvons affirmer que la fabrication du savon demandebeaucoup d’attention et de précision si non, le savon ne comportera pas toutes ses propriétésspécifiques telles que la mousse et sa fameuse propriété nettoyante. Ces propriétés influencentsur l’efficacité du savon.Notre travail réalisé nous a permis de préparer une savonnette à base d’huile d’olive,d’huile de coco et d’huile de ricin utilisant deux procédés de fabrication :? la saponification à froid dans lequel les savons conservent leurs propriétés? la saponification à chaud qui conservent les propriétés des huiles ajoutées à la trace (latrace du mixeur sur le mélange).Pour cela on a premièrement calculé la quantité de soude pure et connaissant la concentrationde la lessive de soude en degré baumé on a déterminé la quantité de lessive à utiliser.Après utilisation des savonnettes pendant un mois on a constaté qu’elles sonthydratantes moussantes et tiennent dans le temps.En perspective nous insisterons sur certains points qui nous paraissent important àpoursuivre à savoir :? Ajout des colorants, conservateurs et agents antiseptiques naturels Améliorer la consistance des savons liquides Extraction d’huiles essentielles afin de parfumer les savons car ce qui se vendentau niveau du commerce ne sont pas purs et ne sont pas suffisamment concentrés Mise en place d’une analyse sensorielle par un jury expert Réalisation d’une étude technico-économique sur les produits finis et établir lecoût de production et le prix de vente d’un flacon de ces savons.
