Background The role of surgery in treating children with functional constipation (FC) is controversial, because of the efficacy of bowel management programs. This case series is comprised of failures: 43 children, spanning 25 years' practice, who had megarectosigmoid (MRS) and unremitting constipation. Purpose To determine whether these children were helped by surgery, and to contribute to fo...

Herein, a soiling measurement tool, termed “SoilRatio,” and its software is presented. The originality of this fully integrated device lies in standalone feature sensors on module scale. It able to quantify precisely, quickly, regardless the type soiling, production loss photovoltaic plant. Most measuring devices consist two similar modules mounted side by side, one cleaned frequently other lef...

Soiling of photovoltaic (PV) modules is a major issue due to its critical impact on PV performance and reliability, especially in the desert arid regions such as state Qatar. frequently results severe reduction power generation, which drastically affects economical profitability plant, therefore, must be mitigated. The most common way mitigating soiling surface cleaning. However, latter could c...

As a clean and sustainable energy source, solar is gaining popularity quickly surpassing other generation methods. However, the accumulation of dirt on surface Photovoltaic panels (PV) significant barrier to harvesting energy. The panel's performance output are negatively impacted by this soiling, which drastically reduces capacity harvest sunlight effectively. Therefore, regular PV module clea...
