Recent studies on superhydrophobic surfaces have revealed the important roles of structural hierarchy in the overall properties of these surfaces. Here, a novel, versatile, and effi cient technique is introduced for fabricating macroscopic hierarchical superhydrophobic surfaces with both well-defi ned primary microstructures and well-ordered secondary nanostructures using electron-beam lithogra...

This paper presents a nonisolated, high boost ratio hy-brid transformer dc–dc converter with applications for low-voltage renewable energy sources. The proposed converter utilizes a hy-brid transformer to transfer the inductive and capacitive energy simultaneously, achieving a high boost ratio with a smaller sized magnetic component. As a result of incorporating the resonant operation mode into...

Postoperative ileus (POI) in patients undergoing abdominal surgery is associated with signifi cant morbidity. In 2008, alvimopan (Entereg®) was approved by the Food and Drug Administration (FDA), and is the only available POI therapy in the United States for patients undergoing bowel resection. Data from preclinical studies demonstrate that alvimopan and its primary metabolite, ADL 08-0011, beh...

The development of affordable photovoltaic technologies, i.e. solar cells, offers one of the most promising solutions for clean, renewable energy. Solution-processed polymer photovoltaic cells have attracted much attention since they can be manufactured with inexpensive, high-throughput techniques. [ 1 ] They are light weight and can also be fl exible, making it possible to integrate them with ...

Daytime hospital for children on base of RICP is used for preventive treatment of sick children with chronic diseases, besides, a number of complications of main disease decreases. The taken analysis has shown that during the 3 years of DH operation a number of emergency medical calls for children with chronic pathologies has decreased by 23 %, frequency of full-day hospitalization has decrease...
