Inflammation or inflammatory reaction is a natural mechanism that will take place when the body is attacked: chemical, toxic, microbial, traumatic. Anti-inflammatory drugs (chemically synthesized drugs) have side effects. The objective of our study is focused on the use of medicinal plants as anti-inflammatory agents we used a cream based on wax and olive oil and seeds of some medicinal plants at different concentration to study the activities anti-inflammatory drugs in vitro in terms of the effect of hemolysis induced by hypotonic solution on the stabilization of the membrane of red blood cells, the effect of inhibiting the denaturing activity of proteins and the effect of reducing the Cytotoxicity. The evaluation of the cytotoxicity of the cream based on olive oil, the seeds of medicinal plants and the natural wax is carried out in vitro by the use of red blood cells. The cream in our study at concentrations (0.3, 0.2 and 0.15 mg / ml), but superior to the hemolytic effect of gallic acid at the concentration of 0.4 mg / ml. The cream did not exhibit an adverse effect on erythrocytes at low concentrations compared to gallic acid which is used in our work as a benchmark polyphony ( L’inflammation ou réaction inflammatoire est un mécanisme naturel qui va se mettre en place quand l'organisme subit une agression: chimique, toxique, microbienne, traumatique.Les anti-inflammatoires ( les médicaments chimiquement synthétisés) ont des effets secondaires. L’objectif de notre étude est concentrée sur l'utilisation des plantes médicinales comme agents anti-inflammatoires nous avons utilisés une crème à base de la cire et l’huile d’Olivet graines de quelques plantes médicinales à différentes concentration pour étudier les activités anti-inflammatoires in vitro en termes d'effet de l'hémolyse induite par une solution hypotonique sur la stabilisation de la membrane des globules rouges, l'effet d'inhibition de l'activité de dénaturation des protéines et l’effet de réduire la Cytotoxicité. L’évaluation de la Cytotoxicité de la crème à base d’huile d’olive, des graines de plantes médicinales et la cire naturelle est réalisée in vitro par l’utilisation des globules rouges. La crème de notre étude aux concentrations (0.3, 0.2 et 0.15 mg/ml), mais supérieur par rapport à l’effet hémolytique de l’acide gallique à la concentration 0.4 mg/ml. La crème ne présentait pas un effet nocif sur les érythrocytes à de faibles concentrations par rapport à l’acide gallique qui est utilisé dans notre travail comme un poly phénol de référence

This is a prospective cross-sectional comparative control studydone in the period between August 2002 to January 2003 in Jabier AbuAlaiz Diabetic Centre, to assess the risk factor of hypertension on type 2diabetic patients and the efficacy of antihypertensive agents on control ofBP and metabolic paremeters.Ninety-two patients with type 2 diabetes were studied, 58.2% ofthem were hypertensive diabetic.The results of this study revealed that, in hypertensive diabeticpatients there was an increase in the incidence of diabetic complicationsespecially angina, heart failure, and renal impairment.In this study 87% of hypertensive diabetics were treated withmonotherapy, calcium channel blockers, B-blockers and angiotensinconverting enzyme inhibitors were the most common group of drugsused. Only (13.2%) of hypertensive diabetic had achieved optimal SBP,and 48.2% had achieved optimal DBP.The study showed that our diabetic patients had poor glycaemiccontrol as the mean Hb A1c was 10.4%, also there was a high incidenceof hypercholesterolemia (31.6%) and hypertriglyceridemia (50%) inparticular among hypertensive diabetic patients.

This study has analyzed and evaluated the current water pricing policies in Ramallah and Al-Bireh District, which do not satisfy the full cost recovery principle. An important aspect in analyzing the current pricing policies was calculating the true cost/ benefit values for investment, operation & maintenance, unaccounted for water and depreciation in order to determine the efficiency of the current tariffs in water utilities. Moreover it looked for Public affordability and willingness to pay that should be assessed towards judging the sufficiency of these policies. Area under study is the center of West Bank, precisely Ramallah and Al-Bireh District; under the occurring political situation it was difficult to move within the district. The current increasing block tariff system applied by Jerusalem Water Undertaking (JWU), and the other providers in the district was in range of (4 -7) NIS/m3, the majority of the population surveyed did not understand how the block system functions and most of them replied that they were not willing to pay any higher amount than 5 NIS/m3 for water services, whereas the same sample replied that they were willing to pay a higher price for disposal of the wastewater.Consequently, conducting this study was difficult as it was based on a field survey involving the distribution of a questionnaire and an analysis of the results in order to build a model that showed a valid understanding of the affordability and willingness of consumers to pay their water bills.The main objectives of this research were to evaluate of the current tariffs for water and wastewater services, suggest modifications if needed, and find the factors affecting tariffs.These were achieved by conducting a questionnaire survey that covers 400 household, analyses of the results using SPSS software, and then two models were constructed to check the hypothesis based on both categorical data analysis, in addition to multiple linear regression.VIIResults analysis revealed that the current tariffs need adjustment and that the proposed variables were significant to willingness of consumers to pay for water and wastewater fees. It can be said that the socio-economic status of residents had no significant impact on their willingness to pay for wastewater or water significantly. However, there were many other determinants that affect consumer willingness to pay for the water services, such as: Knowledge of price paid per cubic meter of water, cost of emptying cesspits for inhabitants who rely on cesspits for sewage collection , availability of water from other sources, and the payment methods used to settle the bills. The percentage of what was paid for water bills to the total income ranged from 4.99% to 5.89%, which did not contradict with the hypothesis stating that 3-5 % of the income was spent on water bills. The analysis also showed that income was not a variable of influence, as it had a confidence value not less than 0.05 which was the opposite of the hypothesis.

En Algérie, le phénomène de l’envasement touche l’ensemble des barrages où plus de 32 million m3 de sédiments se déposent chaque année au fond de ces retenues. Il a été alors plus judicieux de mener une réflexion pour une utilisation rationnelle de.ces sédiments de dragage dans la construction routière. Ce type de sédiments qui nécessite un traitement avant son utilisation L’objectif de la présente étude consiste à établir une synthèse bibliographique sur les différents travaux de recherche qui ont.utilisé les fibres comme technique de traitement et de renforcement des sols Une analyse particulière a été présentée dans ce travail sur les recherches effectuées dans l’étude du comportement mécanique des sols utilisant les fibres végétales de type palmier dattier et les fibres synthétiques de type caoutchouc, comme renfort dans.le traitement des sols en général et des sédiments en particulier

: L'étude des propriétés PVT de gaz naturel est essentielle pour le développement de son production et son exploitation. Le laboratoire est considéré comme la principale source de données pour ces propriétés comme il est possible aussi de calculer ces données à l'aide des équations d'état et des corrélations empiriques avec des marges d'erreurs variables. Ces travail à pour objectif d'étudier expérimentalement un gaz naturel Algérien, en se concentrant sur le calcul du facteur de compressibilité, en utilisant les corrélations relatives pour calculer de ce facteur, tout en essayant de modifier ces dernières avec ce qui correspond au mieux avec le gaz naturel Algérien en se basant sur des outils statistiques et les données expérimentales. Les résultats de cette étude montrent qu'il est possible de développer et d'actualiser les coefficients de corrélations qui correspond mieux avec chaque région géographique pour but de réduire la marge d’erreurs. Summary: The study of properties PVT of natural gas is essential for the development of its production and its exploitation. The laboratory is regarded as the principal data source for these properties as it is possible also to calculate these data using the state equations and empirical correlations with variable margins of error. This work contains an experimental study of Algerian natural gas while concentrating on the calculation of the factor of compressibility, by using the correlations relating to the calculation of this factor while trying to modify them in corresponds with the natural Algerian gas depending on statistical tools and the experimental data. The results of the study shows that it is possible to develop and actualize the correlation coefficients for the special gas for each geographical region in order to decrease the degree of errors.
