Hydrogen is regarded as the potential bearer of energy of the future. Solar hydrogen is the hydrogen produced using renewable energy, particularly solar energy [15,8]. The availability of water and hours of sunshine make Algeria a place of choice for solar hydrogen production. In this work, solar hydrogen production by electrolysis of water is considered. The required energy for water dissociation is supplied by a photovoltaic system. A design and operation study of a photovoltaic system has been done for three different regions in Algeria. The production potential is highly significant particularly in the south parts of this country.
Observational epidemiological studies have the dual goals of measuring disease burden and assessing the association between exposures and outcomes. This report focuses on the first of these goals and provides an overview of design considerations of commonly used approaches, specifically community surveillance studies, cross-sectional studies, and longitudinal cohort studies. Each of these designs has strengths and weaknesses, with no study design being superior in all cases. Rather, these designs are complementary to achieve a better understanding of the burden of stroke.
