Serap Yigit Gezgin, Abdullah Kepceoglu , Yasemin Gündogdu , Sidiki Zongo , Anna Zawadzka, Hamdi ¸Sükür Kiliç and Bouchta Sahraoui; Nanomaterials
In this study, the thin films were produced by using pulsed laser deposition (PLD) technique from gold (Au) nanoparticles deposited on two kinds of substrates under different argon (Ar) gas pressure. Microscope glass slides and silicon (100) wafers were used as amorphous and crystal substrates. The films were deposited under 2 × 10−3 mbar, 1 ×(...)

Temperature Effect on Light Concentration Silicon Solar Cell’s Operating Point and Conversion Efficiency
Mahamadi Savadogo, Boubacar Soro, Ramatou Konate, Idrissa Sourabié, Martial Zoungrana, Issa Zerbo, Dieudonné Joseph Bathiebo
It is well known that temperature acts negatively on practically all the parameters of photovoltaic solar cells. Also, the solar cells which are subjected to particularly very high temperatures are the light concentration solar cells and are used in light concentration photovoltaic systems (CPV). In fact, the significant heating of these solar(...)

The single nucleotide polymorphism (SNP) of the promoter region of MMP-1 (at 1607 bp) and MMP-3 (at 1171 bp) create Ets binding sites. Correlations between these SNPs and sensitivity to several biological processes such as metastasis and recurrence of cancer have been reported in several studies.
In this case-control study, we looked for thes(...)

Patterns for African smart cities semantic data integration
Ferdinand Guinko
Smart communities and cities is a topic widely presented in the scientific litterature. Numerous works have
been done presenting the concept of smart city. But there is still a need concerning the matter of data integration in smart communities and cities. In this paper, we have presented the Users application layer pattern, the Integration m(...)

Arsenic removal with zero-valent iron filters in Burkina Faso: Field and laboratory insights
Anja Bretzler, Julien Nikiema, Franck Lalanne, Lisa Hoffmann, Jagannath Biswakarma, Luc Siebenaller, David Demange, Mario Schirmer, Stephan J. Hug
Groundwater contaminated with geogenic arsenic (As) is frequently used as drinking water in Burkina Faso, despite adverse health effects. This study focused on testing low-cost filter systems based on zero-valent iron (ZVI), which have not yet been explored in West Africa for As removal. The active ZVI bed was constructed using small sized iro(...)

Quelques paramètres physiologiques et constituants biochimiques des organes de la lentille de terre (Macrotyloma geocarpum) en conditions de stress hydrique
Mberdoum Memti NGUINAMBAYE, Rasmata NANA, I. Alain DJINET et Zoumbiessé TAMINI
La lentille de terre est une espèce en voie de disparition car sa culture demeure rudimentaire et traditionnelle. Aucun effort n’est fait pour améliorer cette culture. C’est pourquoi, elle n’occupe pas une place particulière en Afrique comme d’autres cultures vivrières. Ainsi, l’étude a consisté d’une part, à évaluer l’effet de stress sur le t(...)

Impact of road construction on the distribution of Crocodylus suchus (Étienne Geoffroy Saint-Hilaire 1807) in urban park Bangr-Weoogo (Burkina Faso)
Ilassa Ouedraogo, Idrissa Ouedraogo, Noëllie W Kpoda, Adama Oueda, Victor Bance, Justine Kabore, Gustve B Kabre
In contrast to other anthropogenic activities, little is known about impact of road construction on reptile’s distribution in urban areas. Therefore, the present study aimed at quantifying impact of road construction on C. suchus distribution. It was conducted from February 2016 to May 2018, in the urban Park Bangr-weoogo. C. suchus population(...)

Study of the phenomenon of mud increase on the lamellate decanter of the station of treatment of water of Paspanga in Burkina Faso
Elisabeth R. OUEDRAOGO, Crépin I. DIBALA, Kiessoun KONATE, Jean DIARRA et Mamoudou H. DICKO
Drinking water is a basic food and its access is one of the fundamental human needs. For Ouagadougou, it comes from the station of water treatment of surface at Paspanga and Ziga. The mud increase constitutes a persistent phenomenon in the treatments of water of Paspanga. The objective of this work was to find the causes of this phenomenon in(...)
