Titre : Qualité physico-chimique, pollution organique et métalliquedes compartiments Eau / Sédiments de l’Oued Rhumel,et des barrages Hammam Grouz et Beni Haroun Type de document : texte imprimé Auteurs : Meriem Melghit, Auteur ; F. Zohra Afri-Mehennaoui, Directeur de thèse Editeur : Constantine : Université Mentouri Constantine Année de publication : 2012 Importance : 176 f. Format : 31 cm. Note générale : 2 copies imprimées disponibles Langues : Français (fre) Tags : Contamination Qualité Physico-chimie Eau Sédiments ETM Pollution Physical Chemistry Water Sediment Trace metals Index. décimale : 570 Sciences de la vie. Biologie Résumé : This study is part of the context of a multidisciplinary research on terrestrial and aquatic ecosystems. To assess the quality of water of the Rhumelwadi, its tributaries and the water dams HammamGrouzand BeniHaroun, to the organic pollution and possible metal contamination, we conducted for water and sediment compartments a set of physico-chemical approaches: physical and chemical parameters, major mineral elements, pollution parameters and dosage of five ETM (Cd, Cr, Cu, Pb and Zn). This research involved five sampling points for the water compartment, both located at the two dams GrouzHammam and BeniHaroun,
and three on the Rhumelwadi, collected twelve times during 2009. For the sediment compartment, sixteen sampling points were selected in strategic locations and sampled twice during the month of January 2010 and April 2010. The set of parameters determined showed organic pollution characterized by fair to poor quality water from the wadiRhumel. Metallic contamination evaluated by SEM is almost negligible dissolved in water but fairly abundant in sediments which could cause high toxicity for aquatic fauna and flora, mainly marked by
levels of Cd, Cr, Zn and Pb higher than the estimated natural levels. The waters of dams HammamGrouzandBeniHaroun are exposed to pollution from various sources (urban,industrial and agricultural ...) despite treatment of wastewater in STEP. Their sediments show a significant metal contamination. A similar situation is observed for the waters of
Rhumelwadi and its tributaries, where the degree of pollution is important.
To remedy this problem, it would be important to better exploit the wastewater treatment plants, a wastewater collection and mastered most comprehensive, well while managing industrial and municipal discharges, which undoubtedly constitute a major threat to ecosystems aquatic. The purified water supply Rhumelwadi, its tributaries and therefore the
two dams HammamGrouzandBeniHaroun. They contribute to the reduced risk of organic pollution and heavy metal contamination of water and sediment compartments, and water conservation for serene life (better water management).

La distillation énergie solaire eau canaux plaque Distillation solar energy water canals plate Index. décimale : 530 Physique Résumé : Solar distillation whose the basic approach is the natural hydrologic cycle, is suitable for supplying fresh water to small communities (humans or animals) who live in arid and isolated regions where energy and water are insufficient and solar energy is abundant. States of the situations of energy, water and solar distillation in the world have been dressed. From this, two new solar still models have been developed, one theoretically: flowing solution over inclined flat plates solar still; and the other experimentally: canals solar still. To study the effect of significant parameters on the evaporated volume water of a flowing solution on a heated inclined plate or several inclined plates solar still, a mathematical two dimensional flow analysis was carried out based on continuity, momentum and energy equations for the liquid phase. It is shown that the significant parameters are the film thickness, the plate length and inclination, and the heat at the wall which represents the solar radiation absorbed by the plate. In the experimental studies, canals solar still prototype of 0, 6 m2 in area has been designed and tested. The tests have shown the effects of certain atmospheric, design and operational techniques parameters on the output and the operation of the solar still. It has been concluded that the solar radiation, the solar movement pursuit, the distance covered by the solution and a good thermal isolation, have a significant effects on the output of the solar still whose distilled water production has reached an appreciable quantity of 2,7 l (i.e. 4,8 l/m2). Finally, some propositions have been suggested for further study, to develop the two new types of solar stills.

Titre : Utilisation d’ameliorants de l’expansion gazeuse dans la fabrication sans gluten de pains leves traditionnels Type de document : texte imprimé Auteurs : Fairouz Djeghim, Auteur ; Mohammed Nasreddine Zidoune, Auteur Editeur : جامعة الإخوة منتوري قسنطينة Année de publication : 2015 Importance : 120 f.

FP ????? FP ??? ???? Index. décimale : 640 Industrie Alimentaire Résumé : The main objective of this work was the formulation and manufacturing of leavened gluten free Khobz Eddar -by Corn Field bean Formula (FMF) and rice- field bean Formula (FRF) improved by corn or rice flour pregelatinised (FPM or RPF).
A survey by quota with a number of staff from 50 women in the city of Constantine is made. The survey results show that the bread Khobz Eddar is made from durum wheat semolina added salt, yeast, oil, water, egg and sesame and nigella grain. For the manufacture of Khobz Eddar women proceed as follows: Hand Mix dry ingredients, a rest time of 10 min the dough, a kneading 15min followed by molding, proofing (45 min), coking (30 min),cooling and demolding.
A physicochemical characterization of raw materials and rheology of durum wheat semolina by Chopin Alveograph is made. The Response Surface Method (RSM) is used for optimization of the gluten free bread.A central composite design (CCD) with two factors (hydration, pregelatinized flour) and five levels is constructed with the specific volume (Vsp)as the only answer. Intervals of water and FP quantities used are respectively [51 -115] ml
water and [0 to 14.10] g FP corn for FMF and [45-105] ml water and [0 to 12.60]g FP rice for FRF. The effects of hydration and the FP on (Vsp) of gluten free bread were studied. The optimum points are characterized by image analysis and sensory analysis and compared to a control bread durum.
The maxima of the two response surfaces correspond to the pairs (115 ml, 7,05g) for FMF with a Vsp = 2.39±0.02 cm3 / g and (105 ml, 6.3 g) for FRF with a Vsp = 2.24±0.01 cm3 / g. Addition of FP improved the Vsp but they stay lower than control wheat one
(3.64±0.03 cm3 / g).
The image processing shows that the number of the cells in FMF and FRF is greater than that of Khobz Eddar durum .The three loaves of cells (control, FMF and FRF) have a round shape with a form factor (Sh) close to 1.
The preference test allowed to classify optimal gluten-free khobzeddar FMF in second after the control wheat durum bread and followed by the the optimal FRF .The hedonic test showed that there is a significant difference between the gluten-free bread and bread Khobz eddar durum
