In this paper, a flexible, ultra-thin, miniaturized broadband frequency selective surface (FSS) is demonstrated for wideband electromagnetic shielding application. The unit cell of the proposed FSS structure consists cross dipoles loaded with metallic circular strip. has an extremely low profile thickness 0.0009?o and size 0.045?o×0.045?o. This provides more than 20 dB from 1.1 to 2.6 GHz regio...

BACKGROUND Screening flexible sigmoidoscopy is an underused cancer prevention procedure. Physicians often cite patient discomfort as a reason for not requesting sigmoidoscopy, but patient experiences and attitudes toward sigmoidoscopy have not been well studied. OBJECTIVE To measure patient satisfaction and the determinants of satisfaction with screening sigmoidoscopy. METHODS An instrument...

normal 0 false false false en-us x-none ar-sa laryngocele is an air-filled, abnormal dilation of the laryngeal saccule that extends upward within the false vocal fold, in communication with the laryngeal lumen. a case of 43-year-old male with bilateral internal laryngoceles, who has been treated as asthma for 4 years, is presented. the patient had dyspnea, cough, and excessive phlegm for a mont...

Herein, it was investigated the development of a low-cost conductive coating for application in field Electromagnetic Interference shielding (EMI shielding). The produced with reduced graphene oxide (rGO), considered an excellent technological alternative applications, and styrene-ethylene/butylene-styrene (SEBS) block copolymer. rGO obtained by reduction (GO) using ascorbic acid as “green” eff...

Surprising events may be relevant or irrelevant for behavior, requiring either flexible adjustment or stabilization of our model of the world and according response strategies. Cognitive flexibility and stability in response to environmental demands have been described as separable cognitive states, associated with activity of striatal and lateral prefrontal regions, respectively. It so far rem...

Bone resorption around hip stems is a disturbing phenomenon, although its clinical significance and its eventual effects on replacement longevity are as yet uncertain. The relationship between implant flexibility and the extent of bone loss, frequently established in clinical patient series and animal experiments, does suggest that the changes in bone morphology are an effect of stress shieldin...
