The article discusses application of AC/DC/AC converter cooperating with an induction generator in small hydroelectric power plants. The induction generator works with power grid or a separated group of receivers, enabling to generate power even at low speeds of the turbine. The article provides also results of the investigation concerning the functioning of the generator coupled with AC/DC/AC ...

We study the arc and curve complex AC(S) of an oriented connected surface S of finite type with punctures. We show that except for some finitely many special surfaces, the simplicial automorphism group of AC(S) coincides with the natural image of the extended mapping class group of S in that group. We also show that for any vertex of AC(S), the combinatorial structure of the link of that vertex...

Cederholm, M. 2002. Consequences of amniocentesis and chorionic villus sampling for prenatal diagnosis. Acta Universitatis Upsaliensis. Comprehensive Summaries of Uppsala Dissertations from the Faculty of Medicine 1118, 43 pp. Uppsala. ISBN 91554-5225-6. Amniocentesis (AC) and chorionic villus sampling (CVS) are the principal methods for fetal karyotyping. The aim of this thesis was to evaluate...

Two aphidicolin-resistant cell mutants (AC 12 and AC 41) with a fourfold increase in spontaneous frequency of sister chromatid exchanges (SCEs) were obtained out of over 400 aphidicolin-resistant mutants isolated from mouse lymphoma L5178Y cells. They also exhibited three- to fourfold increases in spontaneous frequency of chromosome aberrations (CAs). To determine whether the high level of SCE ...

The present study investigates how effectively lidocaine ions are transported across a cellophane membrane through the application of either a direct current (DC) or alternating current (AC). The cellophane membrane was set on a parallelplate- type acrylic cell with platinum electrodes at both ends, filled with a donor cell of a 1 % aqueous solution of lidocaine and a receptor cell with distill...

the results of standard and augmented surgical treatment of partial accommodative esotropia have been compared in this study.in this sequential matched randomized double blind clinical trial, we studied 48 patients (96 eyes) with partial accommodative esotropia between the ages of 13 to to 144 months, referring to strabismus clinic of farabi eye hospital between 1999-2000. these patients were g...

To study the effect of partial liquid ventilation (PLV) with perfluorocarbon on acute respiratory failure, 3 groups of 17 rabbits were examined to compare. After acute respiratory failure was induced by lung lavage with sea water in 12 of the 17 rabbits, 7 of the 12 rabbits were treated with conventional mechanical ventilation (AC group) and 5 of the 12 rabbits were treated with PLV using perfl...

Probiotics are believed to be beneficial in maintaining a healthy gut microbiota whereas antibiotics are known to induce dysbiosis. This study aimed to examine the effects of the probiotic Saccharomyces boulardii CNCM I-745 (SB), the antibiotic Amoxicillin-Clavulanate (AC) and the combination on the microbiota and symptoms of healthy humans. Healthy subjects were randomized to one of 4 study gr...

BACKGROUND The aim of this retrospective study was to analyse the treatment time and differences between the pre- and post-treatment peer assessment rating (PAR) index and aesthetic component (AC) of the index of orthodontic treatment need (IOTN) scores in children/adolescents with special health care needs (SHCNs), compared to non-special health care needs (NSHCNs) controls. METHODS Based on...

Abstract Background Venous thromboembolism (VTE) is a frequent complication in cancer patients and often detected as asymptomatic peripheral deep vein thrombosis (DVT). However, guidelines for DVT have not been established either general cardiology or onco-cardiology. Furthermore, patients, it generally considered difficult to administer standard doses of anticoagulants due the high risk bleedi...
