T. A. Adedeji, A. O. Awoyemi, N. O. Adedeji, O. A. Bolarinwa and R. S. Owolabi
Consumption of demineralized water can lead to serious health complications. We attempted determining the level of knowledge of health implications of demineralized water among workers in potable drinking water factories in Ilorin metropolis, Nigeria.Systematic random sampling method was used to select 43 factories.Interviewer- administered semi-structured questionnaire was employed as instrument.
Only 34 (17.6%)of the respondentshad professional qualifications related to water purification. Majority (66.8%) had attended at least one training on water purification. Only 26.4% had excellent in-depth knowledge of the different methods of water purification. Combination of sedimentation, filtration and ultraviolet radiation was the most used method.
Most respondents 128 (66.3%) had excellent knowledge of the usefulness of water purification. About two-thirds of the respondents knew about minerals present in water. 38.3% knew the possibility and meaning of water demineralization. Mineral contents of the potable waters were less than minimum expected levels for magnesium and calcium. Only 70 (36.3%) of the respondents had good knowledge of health implications of demineralized water.
Combination of sedimentation, filtration and disinfection would be the best to preserve health-maintaining minerals in drinking water. There is also a need for awareness campaign of health implications of demineralized water among the producers.

Performance Characteristics of Cement Mortars based on Activated Fly Ashes
S K Chaturvedi and A K Sahu
The objective of the investigation was to see the activation potential of poor quality fly ashes and the impact of activated fly ash on strength development behavior in mortar samples. The paper highlights the availability and physical, chemical and mineralogical characteristics of flyash, its activation and experimental results of using activated fly ash in cement mortar. The results of mechanical activation by grinding of fly ash indicated improvement in terms of lime reactivity, fineness and glass content. The cement blends prepared using activated fly ashes showed that the performance of resultant mortar samples improved to a certain limit only. The interpretation of results obtained indicate that the strength development of fly ash containing cement blends have parameters, affecting the process of hydration reaction and strength development apart from the known ones which are being investigated and their extent of impact being established.

Les Grabens Mio-Plio-Quaternaires Aux Confins Algéro-Tunisiens
N. Defaflia, M. Hamimed, L. Gouaidia, S. Boulamia and A. Djerrab
Tous les fossés d’effondrement dans les confins Algéro-Tunisiens coupent les structures atlasiques alpines d’âge fini- lutétien de direction approximative Nord 45º Est. La phase distensive miocène se manifeste par la création du bassin d’EL Ma Labiod au sud de Tébessa et des fossés d’Oulad Soukies à Ouènza et de Foussana-Kasserine en Tunisie. Deux phases alpines de plissements post-miocènes ont été ressenties dans les environs de Tébessa: les plissements du Pliocène inférieur (de contrainte maximale N0°-20°E et de directions des plis N90°-110°E), dont le stade distensif a provoqué l’effondrement du fossé de Morsott et les plissements du Villafranchien inférieur (de contrainte maximale N80°E et de direction des plis N170°E), dont le stade distensif a provoqué l’effondrement du fossé de Tébessa ainsi que celui de Hammamet. Le substratum des fossés de Tébessa et Hammamet est composé d’une mosaïque de horsts et grabens. Quatre stades successifs ont pu être chiffrés au cours de la mise en place du fossé de Tébessa : le premier au Villafranchien inférieur (Pliocène supérieur), le deuxième au Villafranchien supérieur (Pléistocène inférieur), le troisième à la fin du Pléistocène moyen et le quatrième à la fin du Pléistocène supérieur. L’affaissement se poursuit encore actuellement (quelques secousses ont été ressentis entre 1995-2005), parallèlement au soulèvement des marges du graben, dont le substratum s’est enfoncé dans la partie médiane au cours du dernier stade d’effondrement.

Approche Stratigraphique et Sedimentologique de Terrasses Alluviales Quaternaires du Site de Ben Hliem Sud-Ouest de Tébessa, (Algérie)
M. Hamimed, N. Defaflia, L. Gouaidia, S. Abdessadok and A. Djerrab
Une étude stratigraphique, sédimentologique et magnétique a été réalisée sur des terrasses alluviales, riches en outils archéologiques, du site BEN HLIEM, dans le nord-est de l’Algérie. Du point de vue sédimentologique, les sédiments sont dominés par la fraction sableuse suivie par la fraction limoneuse ; les teneurs modérées en CaCO3
sont le résultat de la dissolution des reliefs calcaires avoisinants (calcaire maastrichtien). L’observation morphoscopique des grains de quartz à la loupe binoculaire permet de proposer une évolution plus ou moins importante, puisqu’ils sont souvent émoussés ou sub-émoussés. L'exoscopie des grains de quartz montre que ces grains ont subi une évolution complexe avant leur épisode d’immobilisation dans la terrasse.
Les résultats de l’étude magnétique concordent avec ceux de l’étude sédimentologique. Les valeurs de la susceptibilité magnétique sont fortes dans la partie médiane de la coupe stratigraphique (juste au-dessus du niveau archéologique) et diminuent légèrement dans la partie supérieure. Les plus faibles valeurs sont enregistrées dans la partie inférieure. Les valeurs de la dépendance en fréquence de la susceptibilité magnétique (x
fd) sont fortes tout le long de la coupe stratigraphique et témoignent de la présence d’un mélange de grains de taille monodomaine (MD), pseudo-monodomaine (PMD) et superparamagnétiques (SP) (avec une prédominance des grains SP). La forte concentration de grains de taille SP révèle la présence d’une pédogenèse importante lors de la mise en place des sédiments.

This study investigates the contribution of different heavy vehicles types to rutting damage along the northern part of Malaysian Peninsula based on their actual weight and analysis of more than 350 km of flexible pavements. The traffic volume and weight of more than 5 million heavy vehicles were collected using weight-in-motion stations located along the north-south expressway. Strength and layers thicknesses of north-south expressway flexible pavements were collected using falling weight deflectometer, and coring. Using finite element analysis the effect of the collected weight on flexible pavement rutting life was calculated. Based on the analysis it was found that the majority of rutting damage is caused by the single trailer trucks with four axles.
