Association of Urogenital Symptoms with History of Water Contact in Young Women in Areas Endemic for S. haematobium. A Cross-Sectional Study in Rural…
2016
Female genital schistosomiasis is a neglected tropical disease caused by Schistosoma haematobium. Infected females may suffer from symptoms mimicking sexually transmitted infections. We explored if self-reported history of unsafe water contact could be used as a simple predictor of genital schistosomiasis. In a cross-sectional study in rural South Africa, 883 sexually active women aged 16–22 years were included. Questions were asked about urogenital symptoms and water contact history. Urine samples were tested for S. haematobium ova. A score based on self-reported water contact was calculated and the association with symptoms was explored while adjusting for other genital infections using m…
Strontium and argon isotopic homogenization of pelitic sediments during low-grade regional metamorphism: The pan-African upper Damara sequence of Nor…
1979
Abstract The fine mineral fractions extracted from pelitic sediments of the Eocambrian upper Damaran Mulden Group were subjected to a detailed isotopic study by the Rb-Sr and K-Ar methods in combination with a mineralogical analysis by X-ray diffractometry. The sediments contain two major parageneses of metamorphic origin which can be related to two separate low-grade regional metamorphic events of anchizonal intensity with temperatures between 250 and 300°C and pressures up to 2 kbar. These events are dated at about 535 m.y. and 455 m.y. respectively (with λ( 87 Rb) = 1.42 × 10 −11 yr −1 ). Anomalously high K-Ar ages on samples from specific stratigraphic horizons can be related to open sy…
The Education Production Function reviewed in the framework of Education For All in Sub-Saharan Africa: from theoretical and methodological bounds to…
2007
The Coleman report (1966) was the first of numerous researches exploring quality of learning determinants analysis. With the Education Production Function (EPF), economists have greatly contributed to the extension of this research domain. Actually, empirical works are leading the field with important methodological debates which have fuelled controversies (Hanushek, 2003; Krueger, 2003). Thus, methodological issues have particularly rallied researchers' interests on empirical estimations, while academic researches on the renewal of the theoretical framework have remained scarce despite obvious bounds. Without contesting the validity of miscellaneous estimation problems and the necessity of…

Des observations et des recueils de données ont été réalisés sur leterrain auprès des associations de parents d'élèves, des responsables administratifs, des directeursd'école et des enseignants.
L'uso della comparazione giuridica e i diritti fondamentali nella sentenza della Corte costituzionale sudafricana Case CCT 23/96 "Certification of th…
2008
Obiettivo di questo studio è di esaminare, nel giudizio di conformità operato dalla Corte costituzionale sudafricana nel caso CCT 23/96 Certification of the Constitution of the Republic of South Africa, 1996, a conclusione del processo costituente sudafricano, i richiami comparatistici operati dalla Corte, per verificare il ruolo esercitato dal diritto straniero, in particolare nell’ambito delle previsioni inerenti i diritti fondamentali. L’analisi si sofferma quindi sulla natura dei riferimenti comparatistici, se generali o specifici, sul tipo di formante richiamato (normativo, giurisprudenziale o dottrinale), sull’importanza da dare al richiamo del diritto straniero e sull’uso costruttivo…
Compared regimes of NDVI and Rainfall in semi-arid regions of Africa
2006
International audience; Bi-monthly normalized difference vegetation index (NDVI) at an 8km spatial resolution from the advanced very high resolution radiometers (AVHRR) was used from 1981 to 1995 to analyse the vegetation response to rainfall supply in semi-arid regions of Africa. Within the 200-600 mm annual rainfall belt, for which the apparent NDVI response to rainfall was the strongest, three regions were selected which exhibited different patterns in their NDVI regimes and/or relationships with rainfall. The regions, located in western, southern and eastern Africa, were split into coherent sub-regions in terms of mean regime of photosynthetic activity through a cluster analysis. Overal…
Perspectives on Sustainable Development in the Context of Public Health Issues
2015
Abstract Health is an integral part of sustainable development, a process that can’t be materialized if there is a high prevalence of diseases, a high percentage of those is due to environmental factors. An important component of health is the healthy nutrition, especially of children and pregnant women. Iodine is an essential micronutrient for a good nutrition that covers the physiological needs of the body, iodine deficiency having important consequences for mother and fetus, then for children, especially in the first years of life. The main role of iodine in the body is due to his importance for synthesis of thyroid hormones involved in growth and development of psychic and somatic body,…
An inventory of the names of vascular plants endemic to C Mediterranean and described from Tunisia
2019
The census of the loci classici of the 98 vascular plants described from Tunisia, endemic to Tunisia or to Tunisia and the surrounding countries, is here presented and described. The effective place of publication of accepted names, basionyms, and homotypic synonyms were identified and critically verified. The geographic information on the loci classici was excerpted from the protologues, as well as information on typification for the taxa described before 1 January 1958. The names without holotype are 48. For 7 of them a lectotypification is already available in literature, 5 are lecotypified here, while 32 currently accepted taxa still need type designation. The new names Festuca scholzia…
Global, regional, and national burden of chronic kidney disease, 1990–2017: a systematic analysis for the Global Burden of Disease Study 2017
2020
Abstract: Background Health system planning requires careful assessment of chronic kidney disease (CKD) epidemiology, but data for morbidity and mortality of this disease are scarce or non-existent in many countries. We estimated the global, regional, and national burden of CKD, as well as the burden of cardiovascular disease and gout attributable to impaired kidney function, for the Global Burden of Diseases, Injuries, and Risk Factors Study 2017. We use the term CKD to refer to the morbidity and mortality that can be directly attributed to all stages of CKD, and we use the term impaired kidney function to refer to the additional risk of CKD from cardiovascular disease and gout. Methods Th…
PAN-AFRICAN MOBILE BELTS AS EVIDENCE FOR A TRANSITIONAL TECTONIC REGIME FROM INTRAPLATE OROGENY TO PLATE MARGIN OROGENY
1979
Pan-African belts of the African mainland and the Arabian-Nubian Shield exhibit evolutionary features which are either compatible with intracontinental ensialic development or with plate margin and Wilson cycle tectonics. Some of these belts are discussed and, considered together, they appear to reflect variations in crustal mobility during a transitional tectonic regime from intraplate to plate margin orogeny which lasted some 50. Ma from ca. 1000 Ma to ca. 500 Ma ago.
