Introducing Bio-Degradable Sanitary Towels inSchools in Kitui
Maurine Mukuta Muthengi 이화여자대학교 아시아여성학센터 2015 이화여자대학교 아시아여성학센터 학술대회자료집 Vol.2015 No.7
Universal education is one of the millennial development goal set to be achieved in the world. According to UNICEF there are 31 million girls of primary school age not enrolled in school. Well how can we achieve this goal when girls are not enrolled in school or drop out due to early child marriages and other cultural practices such as female genital mutilation, poverty, lack of school fees, sexual violence and lack of SANITARY TOWELS? How can we achieve this goal when girls miss close to 5 days of school because they cannot afford sanitary towels? In this paper I have explained the problems girls schooling in the rural areas face during their menstruation cycle and the need for introducing an affordable option. Sanitary towels are very expensive and girls from poor families in the rural areas use unhygienic methods during their menstruation such as old pieces of clothes, tissue papers, cotton wool, blankets, tree leaves, feathers, some sit on soil and old goat skins. These girls are more likely to suffer from vaginal infections. Others end up engaging in transactional sex in order to get money to buy sanitary towels this exposes the young girls to risks of getting HIV/AIDS and some end up pregnant thus dropping out of school. The period around puberty many girls drop out of school or are absent for close to 5 days of school. Girls in primary school miss 18 weeks of school a year while girls from secondary school miss 24 weeks in a year. Limited access to safe, affordable, convenient and appropriate methods for dealing with menstruation has far reaching implications for the rights, physical, social and mental wellbeing of many adolescent girls in Kitui, Kenya. For a typical poor Kenyan family there is little money to barely cater for food. Sanitary towels are not a priority. We would like to introduce bio-degradable sanitary towels using banana fibers; they are eco-friendly, hygienic and affordable. Providing these bio degradable sanitary towels to girls would be a life changer for numerous reasons such as hygiene, health, education and empowerment. Because it can greatly improve a girl’s overall school experience, performance and boost self-esteem and confidence. The girls are able to participate fully in class and feel more comfortable.

Tularemia, a re-emerging infectious disease in Iran and neighboring countries
Afsaneh Zargar,Max Maurin,Ehsan Mostafavi 한국역학회 2015 Epidemiology and Health Vol.37 No.-
OBJECTIVES: Tularemia is a zoonotic disease transmitted by direct contact with infected animals and through arthropod bites, inhalation of contaminated aerosols, ingestion of contaminated meat or water, and skin contact with any infected material. It is widespread throughout the northern hemisphere, including Iran and its neigh-bors to the north, northeast, and northwest. METHODS: In this paper, the epidemiology of tularemia as a re-emerging infectious disease in the world with a focus on Iran and the neighboring countries is reviewed. RESULTS: In Iran, positive serological tests were first reported in 1973, in wildlife and domestic livestock in the northwestern and southeastern parts of the country. The first human case was reported in 1980 in the south-west of Iran, and recent studies conducted among at-risk populations in the western, southeastern, and south-western parts of Iran revealed seroprevalences of 14.4, 6.52, and 6%, respectively. CONCLUSIONS: Several factors may explain the absence of reported tularemia cases in Iran since 1980. Tula-remia may be underdiagnosed in Iran because Francisella tularensis subspecies holarctica is likely to be the major etiological agent and usually causes mild to moderately severe disease. Furthermore, tularemia is not a disease extensively studied in the medical educational system in Iran, and empirical therapy may be effective in many cases. Finally, it should be noted that laboratories capable of diagnosing tularemia have only been estab-lished in the last few years. Since both recent and older studies have consistently found tularemia antibodies in humans and animals, the surveillance of this disease should receive more attention. In particular, it would be worthwhile for clinical researchers to confirm tularemia cases more often by isolating F. tularensis from infected humans and animals.

Why hybrid porous solids capture greenhouse gases?
Fé,rey, Gé,rard,Serre, Christian,Devic, Thomas,Maurin, Guillaume,Jobic, Hervé,Llewellyn, Philip L.,De Weireld, Guy,Vimont, Alexandre,Daturi, Marco,Chang, Jong-San Royal Society of Chemistry 2011 Chemical Society reviews Vol.40 No.2
<P>Hybrid porous solids, with their tunable structures, their multifunctional properties and their numerous applications, are currently topical, particularly in the domain of adsorption and storage of greenhouse gases. Most of the data reported so far concern the performances of these solids in this domain, particularly in terms of adsorbed amounts of gas but do not explain at the atomic level why and how adsorption and storage occur. From a combination of structural, spectroscopic, thermodynamic experiments and of molecular simulations, this <I>tutorial review</I> proposes answers to these open questions with a special emphasis on CO<SUB>2</SUB> and CH<SUB>4</SUB> storage by some rigid and flexible hybrid porous materials.</P> <P>Graphic Abstract</P><P>Why and how hybrid porous solids capture gases: exploration combining appropriate <I>in situ</I> measurements and molecular simulations. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c0cs00040j'> </P>

Understanding of the Graphene Oxide/Metal-Organic Framework Interface at the Atomistic Scale
Bonakala, Satyanarayana,Lalitha, Anusha,Shin, Jae Eun,Moghadam, Farhad,Semino, Rocio,Park, Ho Bum,Maurin, Guillaume American Chemical Society 2018 ACS APPLIED MATERIALS & INTERFACES Vol.10 No.39
<P>An atomistic model of the metal-organic framework (MOF) ZIF-8/graphene oxide (GO) interface has been constructed using a combination of density functional theory calculations and force-field-based molecular dynamics simulations. Two microscopic models of GO were constructed integrating basal plane and both basal and edge plane functional groups, called GO-OH and GO-CO<SUB>2</SUB>H, respectively. Analysis of the MOF/GO site-to-site interactions, surface coverage, and GO conformation/stiffness and a full characterization of the interfacial region is provided with a special emphasis on the influence of the chemical composition of GO. It was evidenced that the structure of the GO/ZIF-8 composite at the interface is stabilized by a relatively homogeneous set of interactions between the hydrogen atoms of the −NH and −OH terminal functions of ZIF-8 and the oxygen atoms of the epoxy, hydroxyl, and carboxylic groups of GO, leading to an optimal coverage of the MOF surface by GO. Such a scenario implies a significant distortion of the first GO layer brought into contact with the MOF surface, leading to an interfacial region with a relatively small width. This computational exploration strongly suggests that a very good compatibility between these two components would lead, in turn, to the preparation of defect-free ZIF-8/GO films. These predictions are correlated with an experimental effort that consists of successfully prepared homogeneous MOF/GO films that were further characterized by transmission electron microscopy and mechanical testing.</P> [FIG OMISSION]</BR>
