Seasonal Performance Analysis of Monocrystalline and Polycrystalline Photovoltaic Solar Panels Under Dust Deposition in Niamey, Niger

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT This paper investigates the impact of dust accumulation and temperature on the performance of monocrystalline and polycrystalline photovoltaic (PV) panels under the climatic conditions of Niamey, Niger, with a focus on seasonal variations. High‐resolution performance data were collected across the rainy, Harmattan, and hot seasons to evaluate ...

A probabilistic high cycle fatigue model applied to cast Al-Si alloys [PDF]

open access: yes, 2013
In this work, the high cycle fatigue behavior of cast hypo-eutectic Al-Si alloys is investigated. It is observed that two different coexisting fatigue initiation mechanisms can occur in these materials depending on the presence of different ...

When honeybees come to town: Critical aspects of urban beekeeping and opportunities for regulation

open access: yesPeople and Nature, EarlyView.
Abstract Urban areas are increasingly valued for their role in conserving wild pollinators. Honeybees are often regarded as ambassador species for pollinator conservation, and beekeeping is frequently perceived as a pro‐biodiversity activity, which has become highly popular in urban areas.

Les protéines de choc thermique (heat shock proteins). I : Classification, structure, fonctions et implications dans les processus pathologiques [PDF]

open access: yes, 2002
All living systems have evolved mechanisms to maintain homeostasis in the face of rapid environmental changes. When exposed to elevated temperatures, most of the cells activate the synthesis of a specific group of proteins called Heat Shock Proteins ...

Antioxidative and chaperone‐like activities of a bacterioruberin‐rich extract: An innovative approach to protect the skin proteome

open access: yesInternational Journal of Cosmetic Science, EarlyView.
The bacteriorubin‐rich extract of Arthrobacter agilis has high antioxidative properties, protecting proteins against oxidative stress and preventing their carbonylation. It also protects proteins against saline and heat stresses, suggesting a dual mode of action including antioxidant and chaperone‐like activities.

Acquisition d'images thermiques par drone : corrections radiométriques à partir de données terrain [PDF]

open access: yes, 2014
Thermal images have many applications in agronomy, including crop water stress status assessment. Nowadays, the miniaturization of thermal cameras allows installing them onboard the Unmanned Aerial Vehicles (UAV), but this miniaturization leads to some ...

The integration of storm water flooding and thermal stress potential in Tainan (Taiwan) and Groningen (Netherlands) [PDF]

open access: yes, 2016
Stormwater flooding and thermal stresses of citizens are two important phenomena for most of the dense urban area. Due to the climate change, these two phenomena will occur more frequently and cause serious problems.

Evaluation of the Performance of a Composite Material Made From Lateritic Soil, Crushed Granite, and Cement for Use as the Base Layer of Road Pavement

open access: yesAdvances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
The base layer is important for the road pavement structural performance. This study aims to monitor the performance of various local composite materials as road construction materials. To do this, an experimental study treated the improvement of geotechnical properties of a lateritic gravel, initially nonadopted as a base layer, by using three ...
