Wind and solar energy potential in Herkalou and Lake Assal locations, Djibouti
No full textThe absence of meteorological data to identify the energy resources and the available energy potential represented a major obstacle in some areas in Djibouti. To solve this data problem, in this paper, wind and solar potential were assessed by collecting daily and monthly wind and solar data for the period from 1 January to 31 December 2020, for Herkalou and Lake Assal site. This study highlights that the wind resources in the Lake Assal location are falling into class 7 with high wind speed value of 16 m.s-1 and the wind energy reaching1700 kWh/m2 at 100 m height above ground level. While the Herkalou site shows a lower potential with value of 7.5 m.s-1 and 160 kWh/m2 . The solar potential shows a similar distribution and a constantly high level of solar radiation throughout the year, with the monthly maximum global radiation peaks of around 900 W/m² between 11.00 and 14.00 pm for both sites. The highest monthly average of global solar irradiation values was 5.29 kWh/m2 day-1 and 6.90 kWh/m2 day-1 in March for Herkalou and Lake Assal, respectively. Results obtained in this study are favorable to deploying the solar and wind technologies for the studied sites
A genetic and molecular analysis of flowering time in Arabidopsis thaliana using natural variation = Een genetische en moleculaire analyse van bloeitijd in Arabidopsis thaliana gebruikmakend van natuurlijke variatie
No full textThe natural allelic variation at flowering time loci between two Arabidopsis thaliana accessions; Landsberg erecta (L er ) and the tropical Cape Verde Island (Cvi) has been analyzed. Quantitative trait locus (QTL) mapping in recombinant inbred lines (RILs) grown under three environments, differing in day-length and/or vernalization treatment, was used to detect and locate flowering loci on the genetic map of Arabidopsis. Four main QTLs were identified, designated EDI , FLF , FLG and FLH , to which most of the flowering time differences could be attributed. At the EDI and FLH loci, Cvi alleles resulted in earliness, whereas at FLF and FLG , Cvi alleles caused lateness. Among these QTL, EDI ( EARLY, DAY-LENGTH INSENSITIVE ) is the main locus responsible for day-length sensitivity. To determine the molecular basis of this natural genetic variation, we have isolated the EDI locus using a map-based cloning strategy. The positional cloning of the EDI QTL showed it to be a novel allele of CRY2 , encoding the blue-light photoreceptor cryptochrome-2, that has previously been shown to promote flowering in long-day photoperiods. It was shown that the unique flowering phenotype in the CRY2 -Cvi allele results from a single amino acid substitution that reduces the down-regulation of the CRY2 protein in plants grown under short photoperiods, leading to early flowering. The genetic interaction between CRY2 and other loci involved in the different flowering promotion pathways was studied. The three different types of CRY2 alleles ( CRY2 -Cvi = EDI , CRY2 -L er , and the CRY2 null mutant fha1-1 ) were combined with the mutants representing the different flowering pathways. This analysis indicated that the so called "vernalization and autonomous pathway" that control FLC ( Flowering locus C ) expression, repress the expression of CRY2
Diasporas within and without Africa : dynamism, heterogeneity, variation
No full textThe book deals with two types of “African diasporas”, the first of which originated in the migration histories of the Indian Ocean and brought new groups into Africa. This is illustrated by case studies of Hadrami communities in Sudan and Zanzibar, and the Malay community in Cape Town, that produced trade links as well as processes of Islamization. The second type originated with the failing African states and cases discussed are an Eritrean diaspora in Germany, alongside Sudanese diasporas in Norway and the USA, and a Somali diaspora in Norway. The papers deal with processes of homemaking, political mobilization in the diaspora through local organisations, religious networks and cyberspace nationalism. The central conceptual argument is that “diaspora” is not only a post-modern reaction to the xenophobia of Western nation states but must be seen as part of a broader history of human migration and intercultural experience. This calls for a perspective which takes into consideration historically produced variation and dynamism.CONTENTS -- Diasporas within and without Africa – Dynamism, heterogeneity, variation/Leif Manger and Munzoul Abdalla M.

Sudan: Identity and conflict over natural resources
No full textResource-based conflict constitutes one of the most serious challenges facing many regions in Sudan. Traditionally, resource-based conflict has been represented by the age-old competition between farmers and pastoralists over water and land resources. Due to the protracted nature of conflicts over resources in Sudan, conflicts take on an ugly identity that is tearing the country apart. Conflicts over resources take place at community local levels, but they are often escalated by state policies. Munzoul A.M. Assal argues that understanding conflicts in Sudan requires that we pay more attention to the state and the institutional framework within which conflicts take place.

The Management of the Khan Al-Assal Chemical Attack in Aleppo University Hospital (AUH)
No full textAbstractOn March 19, 2013, Khan al-Assal was attacked with chemical weapons. In total, 20 people were killed and an additional 124 were injured; 63 people were cared for at Aleppo University Hospital on that day, where 14 died, all of them were civilians; 7 men, 6 women, and 1 child. This is a brief first hand report, for what has now become a more frequent, more deadly and horrific event in the lives of many Syrians.

Hallux valgus, ankle osteoarthrosis and adult acquired flatfoot deformity: a review of three common foot and ankle pathologies and their treatments.
No full textThe pathogenesis of hallux valgus deformity is multifactorial. Conservative treatment can alleviate pain but is unable to correct the deformity. Surgical treatment must be adapted to the type and severity of the deformity. Success of surgical treatment ranges from 80% to 95%, and complication rates range from 10% to 30%.Ankle osteoarthrosis most commonly occurs as a consequence of trauma. Ankle arthrodesis and total ankle replacement are the most common surgical treatments of end stage ankle osteoarthrosis. Both types of surgery result in similar clinical improvement at midterm; however, gait analysis has demonstrated the superiority of total ankle replacement over arthrodesis. More recently, conservative surgery (extraarticular alignment osteotomies) around the ankle has gained popularity in treating early- to mid-stage ankle osteoarthrosis.Adult acquired flatfoot deformity is a consequence of posterior tibial tendon dysfunction in 80% of cases. Classification is based upon the function of the tibialis posterior tendon, the reducibility of the deformity, and the condition of the ankle joint. Conservative treatment includes orthotics and eccentric muscle training. Functional surgery is indicated for treatment in the early stages. In case of fixed deformity, corrective and stabilising surgery is performed. Cite this article: Crevoisier X, Assal M, Stanekova K.
