We report on the design, fabrication, and characterization of a novel 90° waveguide step twist with 56% fractional bandwidth. The proposed provides field rotation in frequency range 210–375 GHz. experimental results are good agreement electromagnetic simulations showing an insertion loss below 0.3 dB return better than 20 over most band. ultra-wideband performance, tolerance to fabrication inac...

in this work, we developed a simple and selective method for separation and spectrophotometric determination of trace amounts of cetylpyridinium chloride (cpc) in pharmaceutical products using cloud point extraction (cpe) technique. the method is based on cloud point extraction of the cpc in alkali conditions using of nonionic surfactant triton x-114. under selected conditions, the calibration ...

Various DC-SQUID sensor configurations were developed for use in our 19-channel neuromagnetometer. Apart from the standard type, resistively and inductively shunted SQUIDs were made, allowing for a large screening factor p (>l). In this way signal coupling from the pick-up coil to the SQUID is facilitated and capacitive coupling between the input coil and the SQUID washer can be decreased. The ...

The objective of this paper is to understand the drivers of consumer choice under risk. We disentangle and study the relative importance of di erent preferences in explaining the high risk premia consumers pay for actuarially unfair insurance. Empirical and behavioral research on insurance is at odds on whether diminishing returns (curvature of the utility function), or loss aversion and non-li...

PURPOSE The aim of this study was to test a simple technique to augment the pullout resistance of an anchor in an over-drilled sheep humerus model. METHODS Sixty-four paired sheep humeri were harvested from 32 male sheep aged 18 months. Specimens were divided into an augmented group and non-augmented group. FASTIN RC 5-mm titanium screw anchors (DePuy Mitek, Raynham, MA) double loaded with su...

BACKGROUND AND AIM The present anti-infection strategy for prosthetic joint infections (PJI) includes the use of antibiotics and surgical treatments, but the bacterial eradication rates are still low. One of the major challenges is the formation of biofilm causing poor bacterial eradication. Recently it has been reported that allicin (diallyl thiosulphinate), an antibacterial principle of garli...

new units are shipped every year. The impact of this new rule would effectively double the price of purchasing a new washer and eliminate consumer choice through a defacto mandate of side-loading washers. Many have argued that the proposed standards for clothes washers could be met with conventional toploading designs, but the reality is that a sideloading washer design is the only means of ach...

INTRODUCTION The Montgomery silicone tracheal T-tube (Safe-TTube) has gained a role in laryngeal and tracheal reconstruction and revision by providing patients a longterm, indwelling stent that allows voice production and swallowing. Montgomery designed the tracheal T-tube in 1968.l The T-tube is made of silicone and therefore relatively inert and resistant to tissue reaction.2 It can be used f...
