This article examines the extent and manner to which evaluations of flood-related precautions are affected by an individual's motivation and perception of context. It argues that the relationship between risk perception and flood risk preparedness can be fruitfully specified in terms of vulnerability and efficacy if these concepts are put into the perspective of prevention-focused motivation. T...

Inadequate hole cleaning can lead to many problems in horizontal and directional wells. In this work, we tried to investigate the cutting transport phenomenon by an experimental directional drilling simulator, considering the differences between the operational and experimental conditions. The inclination, fluid type (water, foam, viscous, and dense), rotary speed (0 and 110 rpm), nozzle bit si...

In this study, thermodynamic and economic analysis of a photovoltaic electricity generation system (PVEGS) with and without self-cleaning panels is reported. In the first part, thermodynamic analyses are used to characterize the performance of the system. In the second part, the economic comparison of photovoltaic electricity generation with and without self-cleaning panels is carried out for a...

Laser cleaning is a good alternative to ablate and remove contaminants from different samples. To meet the practical demand, we present elemental analysis of Q235 steel samples, using laser-induced breakdown spectroscopy (LIBS) enhance laser process. Two samples were selected kept in water soil for 4 7 days, respectively. Half then cleaned method. The objectives promote application cleaning, ge...
