Identification of highly effective antitrypanosomal compounds in essential oils from the Apiaceae family

2018

The Apiaceae family encompasses aromatic plants of economic importance employed in foodstuffs, beverages, perfumery, pharmaceuticals and cosmetics. Apiaceae are rich sources of essential oils because of the wealth of secretory structures (ducts and vittae) they are endowed with. The Apiaceae essential oils are available on an industrial level because of the wide cultivation and disposability of the bulky material from which they are extracted as well as their relatively cheap price. In the fight against protozoal infections, essential oils may represent new therapeutic options. In the present work, we focused on a panel of nine Apiaceae species (Siler montamon, Sison amomum, Echinophora spi…

Politics of Humanitarianism: The Ahmadiyya and the Provision of Social Welfare

2020

Ahmadi Muslims have combined local contributions and financial support from overseas to support various development projects since the 1920s when they started their mission activities in West Africa. The chapter outlines contemporary social welfare activities of the Ahmadiyya Muslim Community in Ghana and Burkina Faso. Humanitarian aid provided by the Ahmadiyya Muslim Community and its NGO Humanity First is one of the issues favouring public recognition as well as interreligious dialogue to which the Ahmadis are equally strongly committed. Most of the donations for Humanity First come from members of the Ahmadiyya community, as zakat or sadaqa donations. Public recognition is particularly i…

A copula-based approach for assessing flood protection overtopping associated with a seasonal flood forecast in Niamey, West Africa

2016

Flood is one of the most important natural disasters that cause huge loss of life and properties every year around the world. Moreover, the International Federation of the Red Cross and Red Crescent Societies pointed out that floods were by far the greatest cause of homelessness. In West Africa, many countries are damaged from flooding almost every season. Thus, this study aimed to set a seasonal flood forecast model and carried out an evaluation of the level of risk associated with each seasonal forecast. HEC-RAS (Hydrologic Engineering Centers River Analysis System) was used to develop a hydro-dynamical model of Niger river on a 160km reach (80km upstream to 80kmdownstream of Niamey), the…

Understanding the Health Disaster: Research Design for the Response to the 2014 West African Ebola Outbreak

2015

International audience; The 2014 Ebola outbreak in West Africa is the largest ever in history, affecting multiple countries and to this date, the World Health Organization has registered more than 6,500 deaths attributed to Ebola. The challenges arising from this outbreak to responders worldwide do not follow the standard characterisation or response patterns of natural sudden onset vs. conflict disasters. Rather, it is a medical emergency, which is intertwined with multiple challenges in the sectors decision-making, coordination, logistics and information management. In this paper, we present our research framework, which is based on desk research and initial interviews with responders. Th…

Targeted application of an organophosphate-based paint applied on windows and doors against Anopheles coluzzii resistant to pyrethroids under real li…

2017

Abstract Background A novel strategy applying an organophosphate-based insecticide paint on doors and windows in combination with long-lasting insecticide-treated nets (LLINs) was tested for the control of pyrethroid-resistant malaria vectors in a village setting in Vallée du Kou, a rice-growing area west of Burkina Faso. Methods Insecticide Paint Inesfly 5A IGR™, comprised of two organophosphates and an insect growth regulator, was applied to doors and windows and tested in combination with pyrethroid-treated LLINs. The killing effect was monitored for 5 months by early morning collections of anophelines and other culicids. The residual efficacy was evaluated monthly by WHO bioassays using…

Typology of pentad circulation anomalies over the Eastern Africa - Western Indian Ocean region, and their relationship with rainfall

2005

International audience; The aim of this study was to classify the most frequently observed atmospheric circula- tion anomaly patterns in eastern Africa and the adjacent Indian Ocean. As an example of the useful- ness of such a classification, the second objective was to test whether these patterns account for intraseasonal rainfall anomalies in the region. A partitioning algorithm, known as dynamical cluster analysis, was therefore applied to the zonal (U)and meridional (V)components of the wind anom- alies, obtained from the NCEP-NCAR Reanalysis R-2 at the pentad (5 d) timescale. The 3 geopoten- tial levels 850, 700 and 200 hPa were combined. Focus is on the transition seasons (March to Ma…

What characterizes Norwegian nursing students’ reflective journals during clinical placement in an African country?

2015

Abstract Introduction An increasing number of Norwegian nursing students take part in exchange programmes in African countries. Reflective journals are often used to enhance clinical placements learning outcomes. Aim To identify the features that characterized students' experiences reported in their reflective journals during clinical placements in an African country in light of cultural competence. Methods Qualitative text analysis of 350 reflective journals written by 197 students taking part in an exchange programme in one of three African countries. Results The reflective journals were characterized by the students' personal emotions, judgements of others and comparisons between what th…

Land Law in the Eritrean State

2022

Land tenure is a fundamental and – at the same time – very sensitive issue in Africa. This is a common denominator in almost every part of the continent, and Eritrea is not an exception in this regard. The paper illustrates the development of land law in post-independence Eritrea, from the beginning of the development of the Eritrean legal system to the newly issued (but not yet in force) Civil Code. While illustrating the different developments of land tenure in Eritrea, the paper intends to show how traditional law continues to be the reference point for Eritreans with reference to land management, despite any legislative attempt to set it aside.

After African trades: changing in Cignana landscape between Late Antiquity and Medieval age

2017

International audience; In many parts of Sicily, the Late Antiquity represents a period of strong transformation in settlement patterns and landscapes. These changes occur also on an area 20 km SE from Agrigento, on the southern coast of the island: this is the territory around the imperial villa of Cignana (2nd-3th century AD), where the University of Palermo carried out some surveys from 2007. During the surveys more than 30 new topographic units of Late Antiquity were detected: some of them are big and accurately dated, others are small and difficult to interpret. Usually, they have located in easily accessible places, close to springs and the road system. Principally African pottery all…
