The architectonic shift in the semiotic, technology, and social environment paves the way to new perspectives of transformative pedagogies in multiliteracies and multimodal literacy for meaning-making through the configuration of gesture, space, image, sound, action, and various modes. Through a mixed-method explanatory sequential design, this study explores college students’ critical reading comprehension by changing a monomodal text into a multimodal one. In the redesigning process, a group of college students (n=4) were oriented to change a provided monomodal text into a multimodal text for the sake of understanding how the enactment of two different modes of a reading text contributes to enhancing college students’ (n= 47) critical reading and comprehension. To gauge the volume of students’ reflection, elaboration, and analytical thinking, in addition to re-enacting different modes such as visual, audio, linguistic, gestural, and spatial, which were tabulated by deploying a two-stage exam procedure. Moreover, the study captures the participants’ documents and interviews regarding experiencing the redesigning process and the two-stage exam. The second exam scores showed noticeable advancement in the students reading comprehension. Additionally, it demonstrated that students’ critical reading skills improved dramatically. The student designers expressed their motivation and interest in the redesigning process, in which they practiced and promoted their technological and literacy skills by working collaboratively. They also showed their confidence and positive impression about being responsible for their choices. They indicated that multimodality helped them achieve comprehension. Based on the results, the study offered some recommendations for research, transformative pedagogy, multimodal Literacy, curriculum design, and development.

Dans ce mémoire nous nous sommes intéressés à l’élimination de la Tylosine par voied’électrocoagulation. Les principaux objectifs visés par cette étude sont :(i) L’étude de l’influence des paramètres opératoires (densité du courant, temps d’électrolyse,la température de la solution électrolytique et la concentration initiale en Tylosine) sur lacinétique d’élimination de la Tylosine sur des électrodes en fer.(ii) La modélisation du taux d’élimination de la Tylosine par la méthodologie des plansd’expériences. Un plan factoriel complet à deux niveaux a été choisi pour simuler lephénomène étudié, mettre en évidence les différentes interactions significatives entre lesparamètres opératoires et optimiser les paramètres opératoires à partir du tracé des courbes desurfaces de réponses et iso-réponses. Un rendement optimal de 71.33% est obtenu dans ledomaine suivants: [Tylo]0 = 50 mg/L, T = 30°C, i = 10 mA/cm2, t = 89 min.La mesure de la DCO et de la DBO5 et l’estimation du rapport DBO5/DCO de la solutionélectrolysée dans les conditions optimales a montré qu’une partie de la Tylosine est dégradéedurant l’électrolyse et que les sous produits formés ne sont pas biodégradables.

Male infertility appears to be a major clinical problem among men of reproductive age in all societies. Nowadays, there is a marked increase in the infertility rates mainly in males. Idiopathic male infertility is considered to be a multifactorial disorder affected by genetic, environmental, and hormonal factors. In fact, ethnic characteristics also have been suggested to be of clinical interest in the evaluation of this disorder. Infertility is defined as a failure of couples to achieve pregnancy following 12 months of unprotected sexual life. Infertility affects 13–18% of couples, and male factor accounts for up to 50% of all the cases. Viruses, as well as many other microorganisms, are able to interfere with the reproductive function and are suspected to be involved in the development of infertility. Cytomegalovirus (CMV) and human herpes virus type-6 (HHV-6) are also frequently discovered in sperm samples. If cytokine production is disturbed, the reproductive system functions may be damaged; this leads to male infertility. Pro-inflammatory cytokines like IL-6 have direct effects on spermatogenic cell differentiation, testicular steroidogenesis, and spermatogenesis, whereas anti-inflammatory cytokines like IL-10 are also linked to testicular development. This case-control study was done on one hundred specimens collected from male patients subjected to primary and secondary infertility and an apparently healthy control group from Al Sader Medical City / Infertility Center / Al-Najaf Al-Ashraf. The study included 71 infertility patients and 29 controls aged between 22 to 48 years. Utilizing a specific ELISA commercial kit, semen samples and PCR were used for detection of allele-specific polymorphism. Increase in pro-inflammatory cytokines (IL-6), and decrease in immunosuppressive (IL-10), could alter the tolerance to sperm cells in male tracts and reduce the favorable conditions to reach the fecundation and implantation. The results show a significant difference (P<0.05) in CMV. The current study showed a highly significant difference (P<0.001) between control and patient groups in each of CMV and HHV-6 (21.57 ± 11.61 vs. 42.89 ± 17.43), IL-6 (5.91 ± 1.28 vs. 7.86 ± 1.95), and IL-10 (14.54 ± 6.23 vs. 20.54 ± 7.90), respectively. The present study has detected the IL-6 polymorphisms, rs1800795 G/C variant, and -590 C/T genotype frequency distribution in infertile male patients. This study revealed the presence of a significant difference in the CC, GC, and GG genotypes between the patient group and the control group. This difference is represented by the p-value calculated as (0.03). Regarding the type of infertility according to genotype in the patient group, it showed a non-significant difference in CC, GC, and GG genotypes in primary and secondary types of infertility (P=0.82). This study revealed that IL-6 most probably has a role in male infertility cases which are associated with infection, immuno-infertile cases, and with varicocele. Moreover, the simultaneous determination of IL-6 allele-specific polymorphisms provides a sensitive and useful marker of silent infection and inflammation of the male genital tract.

Due to environmental and energy security concerns, low emission vehicles present a vital necessity for clean transportation. In particular, Electric Vehicles (EV) are the most promising solution due to the fact that the electrical power system is the most ready infrastructure to supply their requirement. Two possible energy delivery solutions to the EVs, namely the charging stations and the Battery Exchange Stations (BES), are taking the interest of the research nowadays. In this research, a new operation approach is proposed for the BESs. The proposed approach models and optimizes the performance of the charging, discharging and the replacement of the batteries throughout the day taking into consideration the customers arrivals to the BES. The main targets of this approach are to satisfy the EV owners charging requests and to minimize the operating costs. In addition, the batteries in possession of the BES are used to secure more profit to the investor by performing energy arbitrage and supplying ancillary services to the grid. This thesis is targeting the EV manufacturers and EV charging service providers who are directly affecting the development of the EV market. The BES operation optimization problem is formulated as mixed-integer nonlinear programming and is solved as a day-ahead operational problem. The behaviour of charging/discharging power, the state of charge and the stored and replaced energy for all batteries in the station is observed for different case studies. The effect of different aspects such as the grid power limitation, solar photovoltaic system addition and battery self-degradation on the operation of the BES is designed and discussed. Also, a comparison between the charging station operation and the BES is conducted and the results show the benefits of implementing the concept of BES on the EV market. The results prove the effectiveness of the proposed approach in satisfying the EV owners and maximizing the BES investor profit.
