Fossil fuels and their use to generate energy have multiple disadvantages, with renewable energies being presented as an alternative this situation. Among them is photovoltaic solar energy, which requires installations that are capable of producing in optimal way. These will specific characteristics according location meteorological variables the place, one these factors soiling. Soiling genera...

Abstract High levels of airborne dust, frequent dust storms and infrequent rain events are some the reasons why soiling can drastically reduce energy yield photovoltaic modules in desert areas. There ongoing increasing efforts to identify appropriate economically feasible strategies that be used mitigate deserts. Both innovative tracking with adapted resting positions during night anti‐soiling ...

Identification of an electrophysiologic sign before defecation can prevent fecal soiling in infants. To identify such a sign, the contractile activity of sigmoid colon was recorded percutaneously in 48 healthy infants. The recorder was equipped with a digital clock synchronized to the recorder so as to set off an alarm upon significantly increased electromyographic activity of sigmoid colon. Ex...

This paper presents a comparative analysis of single, double, and three-diode models for commercial industrial photovoltaic (PV) cells. The efficiency PV system depends on various factors, including fill factor, material effect, temperature coefficient, interconnections, module degradation, solar irradiation, temperature, soiling, potential induced tilt angle, parasitic resistance, shading effe...

Banknotes are widely exchanged for goods and services worldwide. During its circulation, it can get contaminated by money counting machines, atmosphere, dust, soil, storage process or during usage. soiling level is considered the most predominant reason classifying notes as defective, so reduction should be first aim of developing more durable banknotes. Many countries begin to apply clean note...
