Extension of the Cochrun-Grabel method to allow for mutual inductances

The Cochrun-Grabel (C-G) method, an algorithm for finding the characteristic polynomial of a circuit containing reactances, has so far been restricted to circuits not employing mutual inductances. In this paper we present an intuitive, yet rigorous, proof of the Cochrun-Grabel method for a general RLC circuit, and we extend the method to allow the analysis of an RLC circuit containing mutual induc

Deaf teenagers with cochlear implants in conversation with hearing peers.

Background: This study investigates the use of requests for clarification in conversations between teenagers with a cochlear implant (CI) and hearing peers. So far very few studies have focused on conversational abilities in children with CI. Aims: The aim was to explore co-construction of dialogue in a referential communication task and the participation of the teenagers with CI in comparison wit

Enhanced cerebrovascular expression of matrix metalloproteinase-9 and tissue inhibitor of metalloproteinase-1 via the MEK/ERK pathway during cerebral ischemia in the rat.

BACKGROUND: Cerebral ischemia is usually characterized by a reduction in local blood flow and metabolism and by disruption of the blood-brain barrier in the infarct region. The formation of oedema and opening of the blood-brain barrier in stroke is associated with enhanced expression of metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1). RESULTS: Here, we found an inf

Treatment of acute vestibular neuronitis with glucocorticoids.

OBJECTIVE: : To report the effects of glucocorticoid treatment of acute vestibular neuronitis on recovery of vestibular function and length of hospital stay. STUDY DESIGN: : Prospective, consecutive case series compared with historic controls. SETTING: : Secondary referral academic hospital. PATIENTS: : Patients with acute vestibular neuronitis. One group treated with glucocorticoids within 3 d

How to recondition ex vivo initially rejected donor lungs for clinical transplantation: clinical experience from lund university hospital.

A major problem in clinical lung transplantation is the shortage of donor lungs. Only about 20% of donor lungs are accepted for transplantation. We have recently reported the results of the first six double lung transplantations performed with donor lungs reconditioned ex vivo that had been deemed unsuitable for transplantation by the Scandiatransplant, Eurotransplant, and UK Transplant organizati

Treatment of cricopharyngeal dysfunction: a comparative pilot study.

Cricopharyngeal dysfunction is a narrowing at the level of the upper oesophageal sphincter caused by failed or incomplete sphincter opening as a result of lack of pharyngoesophageal coordination or reduction in the muscular compliance of the upper oesophageal sphincter. Oropharyngeal dysphagia is a typical symptom. Videomanometry allows direct comparison of pressure readings with dynamic anatomy d

Use, non-use and perceived unmet needs of assistive technology among Swedish people in the third age.

Abstract Purpose: To describe the most prominent use of or perceived unmet need of assistive technology (AT) and to compare the characteristics of users, non-users and those expressing perceived unmet need with respect to overall health, independence in everyday life, environmental barriers and socio-demographic features. Method: The study is based on data collected in the "Home and Health in the

Vertical Nanowire High-Frequency Transistors

Popular Abstract in Swedish Minns du din första dator? Kanske köpte familjen den på avbetalning genom jobbet för 20 000 kr och kanske kan du såhär i efterhand tycka att effektförbrukningen var lite väl hög i relation till datorns prestanda. Den gick t.ex. inte att köra på batteri. Detta är ganska långt ifrån dagens datorer, smart-TV, smarta telefoner och surfplattor där vi kan streama filmer och mThis thesis explores a novel transistor technology based on vertical InAs nanowires, which could be considered both for low-power high-frequency analog applications and for replacing Si CMOS in the continued scaling of digital electronics. The potential of this device - the vertical InAs nanowire MOSFET – lies in the combination of the outstanding transport properties of InAs and the improved elec

The role of multilateral environmental agreements in armed conflict: ‘Green-keeping’ in Virunga Park. Applying the UNESCO World Heritage Convention in the armed conflict of the Democratic Republic of the Congo

This article analyses the application of the 1972 United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Convention (the WHC) in the context of the armed conflicts that have taken place in the Virunga National Park (the Park), a natural world heritage site in the Democratic Republic of the Congo (the DRC). Instead of addressing wartime environmental damage under t
