Helicobacter pylori （H. pylori） colonize the gastric mucosa of 50% of the world＇s population. This infection is closely associated with the development of peptic ulcer disease and gastric cancer. The present study was conducted to assess the prevalence of H, pylori infection in Moroccan population and the risk to develop gastric precancerous lesions and gastric cancer. Totally, 298 patients were enrolled, 68 of asymptomatic subjects and 230 of patients with gastric diseases. Histological examination was effected to diagnostic gastric lesions and to detect H. pylori. ELISA was used to determine H. pylori status of patients. The prevalence of H. pylori within asymptomatic and symptomatic subjects was observed higher. A significant relationship was detected between H. pylori infection and the risk of gastric diseases （p-value 〈 0.0001）. A meaningful association between chronic gastritis increasing and age was observed （p-value = 0.03）. The risk to develop gastric cancer among infected patients was observed elevated with rate of 9%. Our results showed a high prevalence of H. pylori in both asymptomatic and gastric diseases patients. We noticed that chronic gastric infection increases with age. We remarked also that the risk to develop gastric cancer among infected patients was elevated in our population.

The elementary mechanistic model of adsorption and sorption is based on a simple hypothesis： the adsorption sites are uniformly distnbuted on the surface of the pore walls in the adsorbent, the sorption sites are uniformly distributed in the volume of the polymer. In this first paper we will analyze the simple case where one solute molecule is only allowed to occupy a single adsorption or sorption site. A common elementary occupation law of the free sites is assumed： the differential increase of the number of the adsorbed/sorbed molecules is proportional to the differential increase of the activity of the solute and the concentration of the free （non-occupied） sites in the solid. The proportionality coefficient is called affinity coefficient depending on the solid/solute couple and on the temperature and independent of the concentration of the solute. In adsorption the concentration of the free sites is a surface concentration on the pore walls and in sorption it is expressed by the molarity. The simple monolayer adsorption law of Jovanovic is obtained： n = no（1 - e KP） where n is the number of moles adsorbed when the pressure is P. no is the total number of adsorption sites and K the affinity coefficient for adsorption. The sorption law writes： a = 1/k [Ф/1-Ф] ＋ 1-r/k In [1 ＋ 1/r Ф/1-Ф] where Ф, r and k hold respectively for the volume fraction of the solvent in the polymer, for the ratio of the molar volumes of the solvent to the elementary polymer chain containing one single adsorption site and for the sorption affinity coefficient. The confrontation of these equations to experimental isotherms is satisfactory in comparison with the classical Langmuir and Flory-Huggins equations： the best results are obtained for adsorption of vapors on a 5A zeolite and for all analyzed sorption results.

This article provides a review of the research unde rt aken in order to determine the suitability of utilizing microwave technology in the production of Recycled ABS Acrylonitrile Butadiene Styrene resin for mouldin gs. The experimental investigation determined the suitability of the existing re cycled ABS material, the mould material used with respect to performance and lon gevity, potential commercial plant and equipment, end mould compression. Introduction Frequency Characterization of ABS The first step in microwave processing of any material is to locate a frequency band suitable for the mateiial, where it absorbs microwave energy readily. To lo cate this band width, the ABS material was characterized in Variable Frequency M icrowave Ovens operating between the frequenc’y ranges of 2.5 GHz to 6.5 GHz an d 6 GHz to 18 GHz. The variable frequency microwave oven records forward and ref lected powers over regular intervals in the swept frequency range and enables ca lculation of Re flec tan ce=Re fla tan ce forwrd PowerForward Power (1) A low reflectance indicates that the material Forward Power absorbs rela tively higher amount of incident microwave energy. Characterization of the PBS material showed clearly that a frequancy Fig.1 Lower frequency range vs. reflectance of ABS at room te mperatureFig.2 Lower frequency range vs. reflectance of AB S at 80 ℃ 2.5 to 3.5 GHz is the most suitable frequency fo r heating the material. Other alternate frequencies are 12.25 GHz and 15 GHz. Fi g.1. Hazards When ABS is melted a dark fume is omitted, exhaust system was applied, in order to mechanically ventilate and control exposure levels below air borne exposures.

This paper presents the importance of innovation in t he manufacturing enterprise and the need for the engineering education to conver ge with research and innovation. In pursuit of the ultimate manufacturing proces s. Change is inevitable which constantly creates new demands on both engineers a nd the educational system. These demands are consistent with the economic, cultu ral, and social evolution, which finally influence the end technology. In parall el, the change in industrial heating is imminent due to the rises in the cost of fossil fuel and the environmental considerations. Microwave processing offers t he process industry an alternative with some distinct advantages.
