Unease and Free Act in Ceci n’est pas un miroir by Mokhtar Chaoui
No full textDiscomfort is afeeling of individual or collective discomfort, which makes you feel bad about yourself. There are a number of factors that cause this feeling and that differ from a person to another. In literature, this feeling is very present because of the importance given by writers to the place of the individual in his social environment. They are therefore interested in the harmful consequences it could have. Mokhtar Chaoui’s Ceci nest pas un miroir is a relevant example. Through the character of Ixe, the author sheds light on the difficult experiences that some persons are forced to endure, and how these will lead them to commit a cruel act described as a Gidian free act.Le mal-être traduit une sensation de malaise individuelle ou collective, qui fait que lon se sente mal dans sa peau. Nombre de facteurs peuvent être à lorigine de ce sentiment et qui diffèrent dune personne à une autre. En littérature, ce sentiment est très présent étant donné limportance accordée par les écrivains à la place de lindividu dans son environnement social. Aussi sintéressent-ils aux conséquences néfastes quil pourrait entraîner. Ceci nest pas un miroir de Mokhtar Chaoui en est un exemple pertinent. À travers le personnage dIxe, lauteur projette la lumière sur les épreuves difficiles que lindividu se voit contraint dendurer, et comment celles-ci le conduiront à commettre un acte cruel qualifié dacte gratuit gidien
Innovation et dynamiques identitaires
No full textThe author presents innovation as an evaluating point of view directed by certain actors towards others. He describes it as an area of tension and as a place of expression of three types of identity dynamics. First of all the dynamics of identity transformation which aim at the reduction of a current discrepancy between real-life identity and wished for identity. Then, the dynamics of identity preservation aiming at preserving a possible discrepancy between acquired identity and assigned identity. Finally, the dynamics of identity maintenance whose objective is to prevent the advent of a virtual difference between current identity and wished for identity, which agree at the present moment of personal evolution.L'auteur présente l'innovation comme point de vue évaluatif porté par certains acteurs sur d'autres. Il la décrit comme espace de tensions et comme lieu d'expression de trois types de dynamiques identitaires. Tout d'abord, les dynamiques de transformation identitaire qui visent la réduction d'un écart actuel entre identité vécue et identité visée. Ensuite, les dynamiques de préservation identitaire visant le maintien d'un écart possible entre identité acquise et identité assignée. Enfin, les dynamiques d'entretien identitaire ayant pour objectif d'empêcher l'avènement d'un écart virtuel entre identité actuelle et identité visée qui, dans le moment présent de la trajectoire personnelle, sont concordantes.Kaddouri Mokhtar.

Microfiltration, Nano-filtration and Reverse Osmosis for the Removal of Toxins (LPS Endotoxins) from Wastewater
No full textLipopolysaccharide (LPS) endotoxin, a bacterial byproduct abundantly present in wastewater, is more and more representing a major concern in wastewater treatment sector for the potential health risk it represents. It is, therefore, more urgent than before to protect consumers from contaminating their fresh potable water reserves with LPS endotoxin through aquifer replenishment using reclaimed wastewater or by supplying reclaimed wastewater as potable water. Membrane treatment is an alternative to activated sludge process and is the most commonly used to treat wastewater. Moreover, nano-filtration and reverse osmosis are the most advanced technologies used to treat wastewater to a potable level. Removal efficiency of LPS endotoxin using Membrane bioreactors (MBRs) and Nanofiltration (NF) and Reverse Osmosis (RO) is subject of this paper. It revealed that these advanced technologies could remove a significant amount of endotoxin. However, levels of concentration in the product water are still much higher than the one found in tap water and it is not advisable to supply this water directly to consumers. Further investigations are required to determine the best management practices for a safe supply of potable water from reclaimed wastewater
Microfiltration, Nano-filtration and Reverse Osmosis for the Removal of Toxins (LPS Endotoxins) from Wastewater
No full textHeat shock protein 47 stress responses in Chinese hamster ovary cells exposed to raw and reclaimed wastewater
No full textAs wastewater reclamation and reuse becomes more widespread, risks of exposure to treated wastewater increase. Moreover, an unlimited number of pollutants can be identified in wastewater. Therefore, comprehensive toxicity assessment of treated wastewater is imperative. The objective of this study was to perform a comprehensive toxicity assessment of wastewater treatment systems using stress response bioassays. This powerful tool can comprehensively assess the toxicity of contaminants. In this study, samples from conventional activated sludge treatment, membrane bioreactors (MBRs) with different pore sizes and sludge retention times (SRTs), rapid sand filtration, coagulation, nano-filtration (NF) and reverse osmosis (RO) were investigated. The results of stress response bioassays confirmed that the secondary effluent showed higher stress response than influent indicating that biological treatment generates toxic compounds. The results obtained from molecular weight fractionation of water samples demonstrated that organic matter with a higher molecular weight fraction (>0.1μm) causes toxicity in secondary effluent. Furthermore, supernatant from MBR reactors showed toxicity regardless of SRT. On the other hand, stress response was not detected in MBR permeates except for an MBR equipped with a larger pore size membrane (0.4μm) and with a short SRT (12 days). While rapid sand filtration could not remove the toxic compounds found in secondary effluent, coagulation tests, operated at an appropriate pH, were effective for reducing stress response in the secondary effluent. Experimental findings also showed that stress response was not detected in cases of NF and RO permeate subsequent to MBR treatment
Forward Osmosis (FO) Membrane Fouling Mitigation during the Concentration of Cows’ Urine
No full textFO membrane fouling mitigation during the concentration of cows’ urine was investigated. In particular, the effects on the permeability recovery of cleaning methods such as membrane washing with deionized (DI) water, osmotic backwash, and chemical cleaning were studied. The characterization of foulants that accumulated on the membrane surface was found to be rich in sugars and proteins. The foulants were effectively removed by de-ionized water circulation (washing) and osmotic backwash. While osmotic back was more effective, it did not fully recover the permeability of the membrane. The foulants absorbed in the membrane pores were found to be mainly composed of sugars. Soaking the membrane in a solution of NaClO enabled the removal of foulants absorbed inside the membrane. It was revealed that soaking in 1% NaClO solution for 30 min achieved the best results (83% permeability recovery), while soaking for a longer time (10 h) using 0.2% NaClO resulted in counterproductive results
Development of Absorbent Using Amylose-Graphite Composite Electrode for Removal of Heavy Metals
No full textAmylose of Phragmites Australis captures heavy metals in a box consisting of sugar chains. However, its absorption rate is low in the period of the month scale. Therefore, the electrochemical driving force was used to promote the absorption rate in this research. Amylose was doped with TiO2 porous graphite electrode. The composted absorbent was characterized using XRD(X-ray diffraction), SEM (Scanning Electrode Microscopy), Raman spectroscopy, and electrochemical methods. The affinity and maximum absorption amount were calculated using the isotherm method. In this study, Pb2+, Cu2+, Cd2+, and Cr6+ were chosen to demonstrate because these heavy metals are significant pollutants in Japan's surface water. It was found that the maximum absorption was Cu2+ (56.82-mg/L) > Pb2+ (55.89-mg/L) > Cr6+ (53.97-mg/L) > Cd2+ (52.83.68-mg/L) at -0.5 V vs. Ag/AgCl. This is approximately the same order as the hydration radius of heavy metals. In other words, the absorption amounts were determined by the size of heavy metal ions. Subsequently, the mixed heavy metal standard solution was tested; the maximum absorption amount was 21.46 +/- 10.03 mg/L. It was inferred that the electrochemical driving force could be shown as the ion size effect in the mixed solution. Despite there being no support for this hypothesis at this time, this study succeeded in showing that the electrochemical driving force can improve the ability of the absorbent
Textual narrative and visual imagery themes portrayal in Isis's Rumiyah magazine issue 1 / Rabiatul Kamsina Md Yusof and Mokhtar Muhammad
No full textISIS is one of the top extremist radical terrorist group in today’s era. Their extreme action of jihad and radical Islamic fundamentalist ideology attract many believers to follow their path. The number of their followers shows a significant increasing of number recruited from many countries has threatened the global community. The results of this study would provide insights into the propaganda tools use by ISIS as their strategic psychological warfare to attract potential followers through their online digital magazine, titled ‘Rumiyah’. This study observed and analysed the common textual narratives and visual imagery theme use by ISIS in their first Rumiyah issue. The content analysis of descriptive qualitative approach were used to analyse the data. The research is divided in two parts of analysis which is, Textual Narrative Analysis and Visual Imagery Analysis. The coding theme was used as a guideline in collecting the data. In textual narrative analysis, the result shows that ISIS use 66 times Quran verses, with total 29 different Surah. Besides, 3 new basic theme were developed and 40 sub-themes were identified. In the other side, under visual imagery analysis, the result shows that the total 33 different types of images from Rumiyah has atleast one themes match with the basic theme. The result also shows that all common themes used by the author has a negative tonality and tend to have a favourable toneorientation towards ISIS. Thus, this study shows that content in Rumiyah online magazine is dangerous to be read alone because it will affect one’s own faith towards Islamic religion. This magazine use a strategic psychological warfare of propaganda element by manipulating the textual narrative and visual imagery content to disseminate their ideology, inflict fear, influence their targeted audience and to recruits potential followers
