VERRES CHALCOGENURES POUR L'OPTIQUE INTEGREE
No full textThe interest of the chalcogenide planar waveguides for infrared applications like environmental metrology, optical amplification or spatial interferometry is shown. The realisation of such waveguides by stacking and etching un-doped or doped films is than described, stage by stage. The first one consisted in acquiring the control of the radio-frequency chalcogenide thin film sputtering. Good quality and reproducible thin films were obtained. The relation between the optical properties and the films thickness was shown. The second stage was the erbium-doped chalcogenide thin film deposition. The presence of Er(3+) ions was higlighted by the photoluminescence measurements. Photoluminescence lifetime values are encouraging. The third stage of the planar waveguide realisation was the thin film etching : three different etching ways (chemical, plasma and reactive plasma etchings) were tested and compared. Good quality ribs were obtained whatever the method employed. The last stage described in this manuscript is the realisation and characterisation of the waveguides : two types of waveguide (TIR and ARROW) were realised and tested successfully.L'intérêt des guides d'onde à base de couches minces chalcogénures pour des applications dans l'infrarouge comme la métrologie de l'environnement, l'amplification optique ou l'interférométrie spatiale est démontré. La réalisation de ces guides par empilement et gravure de couches non dopées ou dopées erbium est ensuite décrite, étape par étape. La première d'entre elles a consisté à acquérir la maîtrise du dépôt des verres chalcogénures purs par pulvérisation cathodique radiofréquence. Des films de bonne qualité et aux propriétés reproductibles ont pu être obtenus. La dépendance des propriétés des films en fonction de leur épaisseur a été mise en évidence. La deuxième étape concerne le dopage erbium des couches minces chalcogénures, pour la réalisation de composants actifs. L'introduction de l'erbium sous sa forme optiquement active Er(3+) a pu être mise en évidence par la présence du phénomène de photoluminescence dans les couches. Les premières mesures de durées de vie sont par ailleurs très encourageantes. La troisième étape de la réalisation des guides d'onde est la gravure des couches guidantes : trois types de gravure (gravures chimique, sous plasma inerte et sous plasma réactif) ont été testés et comparés. Des marches de bonne qualité ont pu être obtenues par chacune de ces trois méthodes. La dernière étape décrite dans ce manuscrit est la réalisation et la caractérisation des guides proprement dits : deux types de guide (TIR et ARROW) ont été réalisés et testés avec succès

Changing portrayal of a woman in Bollywood cinema: special reference of movies of Vidya Balan
No full textBollywood cinema had a stereotype image of woman in its movies since the beginning. Women were loaded with the patriarchal values. There portrayal matched with the image of woman which the society had in its mind like that of Sita and Radha (Hindu goddesses). Majority of the roles were those of obedient housewives or obedient daughters.
In the last decade i.e. after 2010, in India, there are more women centric films with women in leading and meaningful roles like Highway (2004, Imtiaz Ali), No one killed Jessica (2011, Raj Kumar Gupta), Kahani (2012, Sujoy Ghosh), Mardani (2014, Pradeep Sarkar, Pink (2016, Aniruddha Roy Chowdhury), Chhapaak (2020, Meghna Gulzar) Thappad (2020, Anubhav Sinha) etc. These movies also have special messages for the Indian masses, and they are helpful in bringing positive changes in the society.
This change is interactive in nature. The changing scenario has made much more space for and options for women in cinema and at same time such cinema can be a useful tool in bringing positive changes in society and that too at a fast pace. These changes as well as this interactive nature need to be properly assessed. The impact of these movies can be used for gender sensitization. Some important events that took place in India will also be summarized as they are catalyst to production of women-centric movies in India.
We will review the famous women-centric movies from that focused on representing strong women and their specific achievements. Comparative study of these movies, film reviews, interviews of stars and actors/actresses as well as various articles and books are consulted for this study. Ultimately, through my research and readings, I will conclude that Bollywood Industry has been finally successful in giving proper roles to the Indian actresses. Also, actresses like Vidya Balan have done highly commendable work that has brought glory to heroines. I chose to include Vidya Balan in this Capstone Research as she is a trendsetter when it comes to top women- centric movies in India like Kahani (2012, Sujoy Ghosh) and Dirty Picture (2011, Milan Luthria).M.A.Includes bibliographical reference
Probing the nature of AFEX-pretreated corn stover derived decomposition products that inhibit cellulase activity
No full textSequential fractionation of AFEX-pretreated corn stover extracts was carried out using ultra-centrifugation, ultra-filtration, and solid phase extraction to isolate various classes of pretreatment products to evaluate their inhibitory effect on cellulases. Ultra-centrifugation removed dark brown precipitates that caused no appreciable enzyme inhibition. Ultra-filtration of ultra-centrifuged AFEX-pretreated corn stover extractives using a 10 kDa molecular weight cutoff (MWCO) membrane removed additional high molecular weight components that accounted for 24–28% of the total observed enzyme inhibition while a 3 kDa MWCO membrane removed 60–65%, suggesting significant inhibition is caused by oligomeric materials. Solid phase extraction (SPE) of AFEX-pretreated corn stover extractives after ultra-centrifugation removed 34–43% of the inhibition; ultra-filtration with a 5 kDa membrane removed 44–56% of the inhibition and when this ultra-filtrate was subjected to SPE a total of 69–70% of the inhibition were removed. Mass spectrometry found several phenolic compounds among the hydrophobic inhibition removed by SPE adsorption.Published version: Humpula, James F., Uppugundla, Nirmal, Vismeh, Ramin, Sousa, Leonardo, Chundawat, Shishir P.

Profiling of Soluble Neutral Oligosaccharides from Treated Biomass using Solid Phase Extraction and Liquid Chromatography-Multiplexed Collision Induced Dissociation-Mass Spectrometry
No full textThermochemical pretreatment of cellulosic biomass improves cell wall enzymatic digestibility, while simultaneously releasing substantial amounts of soluble oligosaccharides. Profiling of oligosaccharides released during pretreatment yield information essential for choosing glycosyl hydrolases necessary for cost-effective conversion of cellulosic biomass to desired biofuel/biochemical end-products. In this report we present a methodology for profiling of soluble neutral oligosaccharides released from ammonia fiber expansion (AFEXTM)-pretreated corn stover. Our methodology employs solid phase extraction (SPE) enrichment of oligosaccharides based on porous graphitized carbon (PGC), followed by high performance liquid chromatography (HPLC) separation using a polymeric amine based column (Prevail Carbohydrate ES) and electrospray ionization time-of-flight mass spectrometry (ESI-TOF-MS) in both positive and negative modes. For structural elucidation on the chromatographic time scale, nonselective multiplexed collision-induced dissociation was performed for quasi-simultaneous acquisition of accurate molecular and fragment masses of neutral oligosaccharids in a single analysis. These analyses directly revealed presence of glucans up to degree of polymerization (DP) 22 without side-chain modifications. Additionally, arabinoxylans with DP up to 6 were detected in the pretreated biomass samples (post-enzymatic digestion). All linkages between sugar units in glucans and arabinoxylans were identified to be p-1-4 linkages based on cross-ring fragment masses. Comprehensive profiling of soluble oligosaccharides also demonstrated that arabinoxylan acetylation was reduced by greater than 85% post-AFEXTM treatment.Published version: Vismeh, Ramin, Humpula, James F., Chundawat, Shishir P.

ITC SOLUTIONS TO ACHIEVE PERFORMANCE AND EFFICIENCY OF HEALTH SERVICES:ONLINE VIRTUAL CLINIC
No full textThe digital era modified the way people work, how the information and the informational resources are defined and organized. The organization which holds, uses and correctly reproduces the piece of information, the knowledge, the intellectual capital, becomes a leader in the proper field of activity. Following the actual tendencies in the digital era connected to the exchange of professional information, I can say that the exchange and sharing of digital information in a global multitude of interconnected computers are essential instruments that can contribute to the development and consolidation of the intellectual potential of the organization. This is why, the access of the individuals to information is an actual requirement of the development of the Romanian society in the context of globalization and world implication o contemporary processes and phenomena. The Digital integration eliminates the barriers that traditionally suppress the circuit of the medical information, lets the goods and services circulate to and from Romania by promoting efficiency as final purpose. Performance is needed in the health system, the transformation of the system of medical services by bringing the benefits of the medical science and technology to all individuals from every community. In order to accomplish these expectations it is needed that all the components that form the health system look at it as a whole and subscribe to modern solutions for improvement so that the quality of health should raise to an unprecedented level. Even if health systems differ from country to country from the organizational and financial point of view, they face the same challenges and problems, respectively the supply of medical care of better quality and keeping under control the health expenses. The use of information and communication technology in the field of medical assistance in order to stock, share, transmit and analyze clinical data and knowledge is more necessary than ever.Internet, communication in real time, health system, medical information system, digital integration, virtual medical assistance, virtual clinic, shared medical information
