Removal of Chromium from Waste Water Using Yam Peel Activated Carbon
Authors: Utsev Terlumun Joseph , Onah M. O. 
Published: March 2017

The paper examined the use of yam peel to develop an adsorbent material with good surface characteristics for the removal of chromium (vi) from waste water. Activated carbons were produced from yam peel under varying conditions; temperature, time and preparation sequence in order to determine the optimum conditions. It's efficiency on the adsorption of chromium from waste water was investigated through batch adsorption studies using direct reading spectrophotometer. Samples of yam peels, 100g each were carbonized under varying temperatures of 100, 200, 300, 400, and 500ºC ,with varying carbonization time of 20, 30, 40, 50 and 60 minutes. The result revealed that 80% of chromium was removed at 200ºC and 40 minutes as the optimum carbonization temperature and time respectively. Effect of preparation sequence was equally evaluated, i.e. raw (powdered form), carbonization without activation, activation with (ZnCL2) before carbonization and activation after carbonization with (ZnCL2) and their adsorbing capacities under an initial concentration of 0.05mg/l were obtained to be 20, 100,100 and 60% respectively. Further increase in concentration results in 100% chromium removal for activation before carbonization and 80% for carbonization without activation. Hence, yam peel activated carbon is recommended for the removal of chromium from wastewater using activation before carbonization procedure at the above optimum conditions.

Nigeria has a large number of remote areas that are not being electrified, this is because the power generated is less than the demand of the country. Garundole village is a typical example, with a population of about 270 is not connected to the main grid. Currently load shedding is being practiced by the Power Holding Company of Nigeria (PHCN) to dispatch the power being generated. Moreover, majority of the people leaving in these remote villages depend mostly on diesel power generator. Thus, there is a need to have an independent generating station for such kind of remote village to ease the living conditions of its inhabitants. This paper therefore, reports the economic assessment of PV/diesel/battery hybrid off-grid energy system as an alternative solution to these remote villages. In this regard, three different system configurations is being be studied and analyzed using HOMER optimization software to carry out the economic analysis of the systems and its technical feasibility. The systems include; standalone diesel generator, hybrid PV/diesel with battery storage and hybrid PV/diesel without battery storage. The result obtained from the study shows that a hybrid PV/diesel with a backup battery has the potential capabilities of replacing diesel powered generator used by individual households independently.

Some factors had been found to explain its effect on student achievement both internal and external factors of students. The comprehensive study that explains these two factors in giving effect jointly to academic achievement is still limited. This study examined the effects of child and family characteristics, parent’s expectation, intrinsic motivation, and self-regulated learning strategies on academic achievement of junior high school. The samples of this study were selected by random sampling. One hundred and forty nine of junior high school students in Bogor, 8th grade, were selectedas samples in this study. This study found that parents expectation were positively affecting intrinsic motivation and intrinsic motivation were positively affecting selfregulated learning strategies. Self-regulated learning strategies were positively affecting academic achievement. Self-regulated learning strategies were found as mediator for the effect of parent’s expectation and intrinsic motivation towards academic achievement. Therefore, parents and teachers should be able to raise the intrinsic motivation of students so that students can perform self-regulated learning strategies that can improve their academic achievement.

Introduction: Male migrants and their sexual partners at home are at increased risk of STIs (Sexually Transmitted Infections) including HIV (Human Immunodeficiency Virus). We aimed to assess the knowledge and attitudes of migrants’ wives regarding HIV and STIs, and to understand risk perception of HIV due to their husbands’ sexual behaviour. Methodology: A cross-sectional survey among 182 migrants’ wives was conducted in two rural villages of Chitwan district in Nepal. The participants were selected through multistage cluster sampling method and data were collected through a questionnaire administered through a face-to-face interview. Results: Nearly all (94%) of migrants’ wives had a good knowledge of HIV, however with some misconceptions. More than two-thirds of the participating migrants’ wives were aware about the risk of HIV infection in migrant husbands and subsequent risk of transmitting themselves through sexual intercourse. Nearly half of the participants reported inability to ask their husbands about HIV and STIs even if they had their doubts. Knowledge of HIV and HIV risk associated with migration were statistically significantly higher in younger women, those who were literate and the longer the period of their husbands’ migration. Conclusion: Despite having generally a good knowledge and awareness of HIV and migration induced HIV risk; migrants’ wives could not discuss sexual health issues with their husbands, thus increasing their vulnerability to HIV and STIs.SAARC J TUBER LUNG DIS HIV/AIDS, 2016; XIII(1), page: 9-15
Solar cosmic rays: 75 years of research
Authors: Miroshnichenko L I 
Published: March 2017

Abstract
The 28th of February 2017 marked the 75th anniversary of the first confident detection of solar cosmic rays (SCRs), a term referring to accelerated solar particles with energies from about 106 to ∼ 1010 − 1011 eV. The present paper reviews the key observational and theoretical results on SCRs that have been accumulated over this period. The history of the discovery of SCRs is briefly described, together with SCR recording techniques and instruments, and some physical, methodical, and practical aspects of SCR generation are discussed in more detail. Special attention is given to mechanisms of charged particle acceleration at and near the Sun. Current ideas on the interaction of solar cosmic rays with the solar atmosphere, peculiarities of their transport in interplanetary magnetic fields, movements in Earth’s magnetosphere, and their impact on Earth’s atmosphere are reviewed. It is shown that this field of space physics has produced many results of fundamental interest for astrophysics, solar–terrestrial physics, geophysics, and practical cosmonautics (astronautics).

Published: March 2017

PREMISE OF THE STUDY:Spermacoceae are mainly an herbaceous group in the Rubiaceae. However, a few lineages are woody and are found in a diverse range of habitat types. Three of the largest woody lineages (Arcytophyllum, Hedyotis, and Kadua) are characterized by their distribution in the moist tropical mountains and have disjunct distribution patterns with respect to their closest relatives. In this study, we explore the cases of derived woodiness in these three lineages and their diversification dynamics in the tropical mountains of Asia, the Pacific, and the Americas.METHODS:By combining phylogenetic results with wood anatomical studies, we estimated timing of origin of the three woody groups, inferred their ancestral traits and ancestral distribution ranges, analyzed their associations with the tropical upland habitat, and elucidated their diversification across tropical mountains.KEY RESULTS:The three woody clades originated and diversified from herbaceous ancestors in close association with the tropical upland habitat during the Miocene. The ancestral range for Asian‐Pacific Hedyotis is Africa/Madagascar and continental Asia for Pacific Kadua. The complex geological history of tropical Asia allowed Hedyotis to diversify faster and create narrow endemics near oceans in the highlands of the Western Ghats in India, Sri Lanka, Southeast Asia including southeastern China, and New Guinea.CONCLUSIONS:The three major woody clades in Spermacoceae have gained their woodiness independently from one another, subsequent to colonization by their ancestors from a different geographic environment. The evolution and diversification along the tropical mountain orogeny is strongly linked with the formation of woody habit and many narrow endemic species.
Tracing Interstellar Magnetic Field Using Velocity Gradient Technique: Application to Atomic Hydrogen Data
Authors: Yuen Ka Ho , Lazarian A. 
Published: March 2017

Abstract
The advancement of our understanding of MHD turbulence opens ways to develop new techniques to probe magnetic fields. In MHD turbulence, the velocity gradients are expected to be perpendicular to magnetic fields and this fact was used by González-Casanova & Lazarian to introduce a new technique to trace magnetic fields using velocity centroid gradients (VCGs). The latter can be obtained from spectroscopic observations. We apply the technique to GALFA-H i survey data and then compare the directions of magnetic fields obtained with our technique to the direction of magnetic fields obtained using PLANCK polarization. We find an excellent correspondence between the two ways of magnetic field tracing, which is obvious via the visual comparison and through the measuring of the statistics of magnetic field fluctuations obtained with the polarization data and our technique. This suggests that the VCGs have a potential for measuring of the foreground magnetic field fluctuations, and thus provide a new way of separating foreground and CMB polarization signals.
« Les séniors en tête de gondole » Âge, compétences et relation de service dans la grande distribution
Authors: Fache Philippe , Waelli Mathias 
Published: March 2017

Depuis plus d’une décennie, les entreprises adoptent progressivement des « politiques actives des âges », en particulier en France où le contexte légal impose depuis 2009 le maintien des séniors dans l’emploi. La grande distribution a historiquement structuré ses organisations autour de la figure de la jeunesse. Paradoxalement, elle est aujourd’hui devenue un véritable laboratoire d’expérimentation en matière d’emploi des séniors. Centré sur des investigations ethnographiques en magasins et auprès de responsables de ressources humaines en France et aux Etats unis, cet article pose la question de la place des séniors dans la relation de service. Il montre qu’elle tend à se consolider autour de deux points d’ancrage : l’identification réflexive entre la clientèle et le personnel au contact d’abord et de l’autre côté la reconnaissance progressive d’une expérience propre à susciter la confiance du client.
Offshore balancing : une stratégie globale plus efficace pour les États-Unis
Authors: Mearsheimer John J. , Walt Stephen M. 
Published: March 2017

Pour la première fois dans l’histoire récente des États-Unis, de nombreux Américains remettent ouvertement en question la stratégie globale de leur pays. Cela ne devrait surprendre personne au vu des résultats désastreux qu’elle a engendrés au cours des vingt-cinq dernières années. Mais en poursuivant une stratégie d’« offshore balancing », les États-Unis renonceraient à leurs ambitieux efforts de remodeler les autres sociétés afin de se concentrer sur l’essentiel, c’est-à-dire maintenir leur domination dans l’hémisphère occidental tout en luttant contre de potentielles puissances hégémoniques en Europe, en Asie du Nord-Est et dans le golfe Persique. Il s’agit plus exactement d’assurer une gestion plus parcimonieuse de leurs atouts afin de maintenir leur suprématie sur le long terme et de protéger leur liberté sur le territoire national.
Géopolitique et géoéconomie de la Chine : nouveau pacte du Quincy ou consensus de Beijing ?
Authors: Hache Emmanuel , Rol Sandrine 
Published: March 2017

Exportatrice nette de pétrole brut jusqu’en 1993, la Chine est devenue le premier importateur mondial en 2014 et le deuxième consommateur, alors que sa production intérieure plafonne autour de 4 millions de barils par jour depuis 2010. La sécurisation des approvisionnements est devenue un axe majeur de la politique de sécurité énergétique du pays. Pour y répondre, la Chine a suivi plusieurs voies : diversification des sources d’approvisionnements, investissements dans les infrastructures d’importations, investissements à l’étranger dans l’amont pétrolier, etc. Au Moyen-Orient comme ailleurs, elle a développé des relations avec chaque pays et est parvenue, jusqu’ici, à ne prendre part à aucun conflit ou différent local. Compte tenu de la singularité de la situation de la zone, la question d’une évolution de la stratégie chinoise mérite d’être posée. La Chine parviendra-t-elle à ses fins sans infléchir sa position non interventionniste ? 1
L’innovation déflationniste
Authors: Noailles-Siméon Patrice 
Published: March 2017

En illustrant son propos par les exemples du prix des télécommunications mobiles en France entre 2008 et 2011, du développement de la micro-électronique, de l’économie numérique et notamment des sites collaboratifs, l’auteur met en évidence le caractère monétaire déflationniste de l’innovation et montre que la valeur globale créée par l’innovation n’est pas liée de façon mécanique à son prix. Il montre comment le « voile monétaire » est modifié par les innovations. Dans un monde où le « voile monétaire » évolue très rapidement sous l’effet d’innovations de rupture, cet article souligne un mécanisme de démonétisation de l’économie : dans certaines conditions, on peut créer de la valeur avec des prix qui baissent, on peut augmenter la richesse globale en baissant le volume monétaire de la production ; la productivité apparente mesurée aux prix courants peut baisser alors qu’elle augmente en réalité. En toile de fond, on aperçoit deux débats fondamentaux sur le rôle économique de la monnaie et sur l’esquisse d’une nouvelle croissance. Comme tous les articles exploratoires sur un sujet encore peu commenté, cet article s’efforce d’abord de définir des notions fondamentales et de préciser quelques questions. C’est autant un programme de travail qu’une synthèse sur les possibilités actuelles d’analyse.
