persistent dysphagia, severe gastroesophageal reflux disease, and refractory vomiting. She had undergone vertical banding gastroplasty (VBG) 5 years earlier to manage her obesity and had successfully lost 90 kg in weight. This was performed following failed laparoscopic adjustable gastric banding (LAGB), in which significant reflux symptoms required deflation of the band. Physical examination w...

in this paper, a photonic crystal waveguide with point defects and lattice constant perturbations of +5%, -5% are being investigated. firstly waveguide structures with constant and specific parameters are being studied and photonic band gap diagrams for te/tm modes are depicted; then pulse propagation in the frequencies available in the band gap are shown. after that, effects of parameters like...

To promise on-line and adaptive traffic engineering in software defined networks (SDNs), the control messages, e.g., the first packet of every new flow and network traffic statistics, should be forwarded from software defined switches to the controller(s) in a fast and robust manner. As many signaling events and control plane operations are required in SDNs, they could easily generate a signifi...

Strain sensors based on individual ZnO piezoelectric fine-wires (PFWs; nanowires, microwires) have been fabricated by a simple, reliable, and cost-effective technique. The electromechanical sensor device consists of a single electrically connected PFW that is placed on the outer surface of a flexible polystyrene (PS) substrate and bonded at its two ends. The entire device is fully packaged by a...

background & aim: saffron (crocus sativus l.) formerly was important in turkey. saffron cultivation has been decreased and it is now only cultivated in three villages in this country. it is triploid and exclusively propagated in a vegetative way by corms. in turkey, saffron is traditionally planted by placing corms in rows randomly without grading or sorting; which results in placement of c...

OBJECTIVE The aim of these experiments was to investigate procedures used when estimating bone-conduction thresholds in infants. The objectives were: (i) to investigate the variability in force applied using two common bone-oscillator coupling methods and to determine whether coupling method affects threshold estimation, (ii) to examine effects of bone-oscillator placement on bone-conduction AS...

BACKGROUND AND OBJECTIVE: Accurate and consistent placement of a patient identification (ID) band is used in health care to reduce errors associated with patient misidentification. Multiple safety organizations have devoted time and energy to improving patient ID, but no multicenter improvement collaboratives have shown scalability of previously successful interventions. We hoped to reduce by h...

Sir, The graft fixation and its stability are a difficult problem after releasing the contracture of the fingers. Various methods have been suggested, but most of them are found to be cumbersome. The authors have designed this device by modifying thin plastic band (commonly used as a hair band). Drill holes are made in a hair band at a gap of about one centimeter with the help of a dental micro...

Little has been reported on fetal diagnosis of choroidal fissure cysts and prediction of the clinical complications that can result. We describe the case of a near-term male infant with prenatally diagnosed choroidal fissure cyst and bilateral clubfeet. His prolonged course in the neonatal intensive care nursery was marked by severe panhypopituitarism, late-onset diabetes insipidus, placement o...

The rapid time-variation of a fading multipath environment can impair the performance of multiple-input multiple-output orthogonal frequency division multiplexing (MIMO OFDM). This paper proposes a pilot placement method for MIMO OFDM systems under time-varying channels with the guard band. The time-varying channel is described by complex exponential basis expansion model (BEM). We discuss the ...
