Penser les énergies depuis les Suds : une anthologie de textes d’Amulya K. N. Reddy (1930-2006)
No full textInternational audienceUne anthologie de textes d’Amulya K. N. Reddy (1930-2006), sous la direction de Frédéric CailleAmulya Kumar Narayana Reddy (1930-2006) a 43 ans, en 1973, lorsqu’il commence ses recherches sur les questions d’énergie et de « technologies appropriées » pour les pays en émergence et leurs nombreuses populations rurales. Membre de l’Institut Indien des Sciences depuis sept ans, il abandonne une carrière brillante de chercheur et de professeur en électrochimie. Il créera un centre de recherche expérimental dans un village du sud de l’Inde, sera un pionnier au niveau mondial des « centres énergétiques ruraux » et des petites centrales villageoises à méthanisation (biogaz), avant de devenir le premier grand spécialiste international des énergies renouvelables issu d’un pays des Suds. Figure iconique dans le monde anglo-saxon sur ces questions, précurseur de la notion de « mix » et de « systèmes » énergétiques, il défendra constamment une approche des énergies soucieuse des besoins des plus modestes, de la gouvernance par les populations concernées, et du respect des milieux naturels. Au long des quarante années de sa seconde carrière, il publie plus de trois cents articles en anglais. Le présent ouvrage présente la première traduction en français de sept d’entre eux
Low-cost and nontoxic highly rectifying diodes using p-type tin monosulfide (SnS) thin films and Ti/Au binary contacts
No full textEco-friendly and efficient rectifying p-n diodes have been developed by using cost-effective and non-toxic fin monosulfide (SnS) thin films. Chemically stoichiometric fin monosulfide (SnS) thin films followed by titanium/gold (Ti/Au) bilayer contacts were deposited on Si substrates and then, the structures were treated by rapid thermal annealing process (RTP) at different temperatures. The impact of RTP treatment on the surface morphology and chemical composition of Ti/Au contacts and SnS films along with their electrical characteristics were investigated. The electrical measurements show that as compared to untreated Si/SnS/Ti/Au structures, the heat-treated structures typically at 200 degrees C possess low electrical resistivity and contact resistance of similar to 3 x 10(-2) Omega cm and similar to 11 k Omega, respectively. Heterojunction formed between p-SnS and n-Si exhibited excellent diode characteristics and possess a high current flow in the order of milliamperes, and excellent rectification factor of 1177@ 5 V

Teacher formative assessment: the missing link in response to intervention
No full textResponse to Intervention (RtI) focuses on the assessment, intervention, and progress monitoring of student academic performance and social behavior. Despite requiring highly-qualified personnel for successful implementation, the implementation of Rtl has not focused on applying its foundational principles towards promoting teacher effectiveness through assessment, intervention, and progress monitoring of teacher classroom practice. Compounding this problem is the lack of availability of reliable and valid teacher assessments to apply in an Rtl model for teacher professional development. This chapter provides a rationale for applying RtI principles to teacher professional development and how teacher formative assessment can improve educator effectiveness, student learning, and social behaviors. The Classroom Strategies Scale (CSS, Reddy & Dudek, 2014), a new multidimensional assessment of instructional and behavioral management practices is discussed as an example of one promising tool for promoting teachers professional development within an Rtl model. We offer a synthesis of the theory, research, and evidence of reliability and validity of the CSS. The application of teacher formative assessment in job-embedded professional development/coaching models for schools is discussed. Finally, implications for practice and research are outlined.Peer reviewe

Ancestral Consanguinity and Mortality Among Three Endogamous Populations of Chittoor District, Andhra Pradesh, India
No full textConsanguineous marriages have been practiced around the globe by many societies from time immemorial, particularly in South India. Consanguineous marriages play a major role in the health of a population, and diseases leading to mortality of the progeny are a consequence of detrimental recessive genes. To evaluate the effects of ancestral consanguinity on mortality in relation to consanguineous marriage, we have ascertained data from 1,500 women belonging to three endogamous communities (Akuthota Reddy, Odde, and Madiga) of Chittoor District, Andhra Pradesh, India. There were 500 women from each community. For each marriage we drew a family pedigree, extended upward to two earlier generations on either side of the spouses to determine the prevalence and pattern of consanguinity, with detailed information on fertility and mortality. We observed a significant difference in the mortality rates between consanguineous and nonconsanguineous marriages when all the marriages of the women, women’s parents, and (women’s) husband’s parents were considered in all three communities. In inbreeding, the offspring of earlier generations might have passed on deleterious genes to later generations (under unfavorable conditions), which resulted in a negative aspect of reproduction (among the offspring of the present couple)

Influence of Low Intensity Aerobic Exercise Training on the Vo2 Max in 11 to 14 Years School Girls in Hyderabad District
No full textExercise training with varying intensity increases maximal oxygen intake (VO2max), a strong predictor of cardiovascular and all-cause mortality. Purpose: The aim of this study was to find out the influence of low intensity aerobic training on the vo2 max in 11 to 14 years school girls in Hyderabad district. Methodology: The research scholar has randomly selected thirty (N=30) high school girls were selected as subjects and their age ranged between 11 to 14 years. The subjects were divided into two equal groups, each group consist of 15 total 30. Group one acted as experimental group (EG) and group two acted as control group (CG). The dependent variable vo2 max was selected and it is measured by manual test. Statistical Tool: The statistical tool paired sample ‘t’ test was used for analysing of the data and the obtained ‘t’ ratio was tested for significance at 0.05 level of confidence. Results: The analysis of the data revealed that there was a significant improvement on vo2 max by the application of low intensity aerobic
