This paper proposes a step-up 3-Ф switched-capacitor multilevel inverter topology with minimal switch count and voltage stresses. The proposed is designed to provide five distinct output levels from single isolated dc source, making it suitable for medium low-voltage applications. Each leg of the contains four switches, one power diode, capacitor. switching signals are also generated using stai...

Systems of coupled nonlinear Schrödinger (CNLS) equations arise in several branches of physics, e.g., optics and plasma physics. Systems with two or three components have been studied intensively. Recently periodic solutions for CNLS systems with four components are derived. The present work extends the search of periodic solutions for CNLS systems to those with five and six components. The Hir...

We performed a histological and histomorphometric examination in five cadaver specimens of the femoral and acetabular components and the associated tissue which had been recovered between 3.3 and 6.2 years after primary total hip arthroplasty (THA) using a proximal hydroxyapatite (HA)-coated titanium alloy implant. All had functioned well during the patients' life. All the stems were fixed in t...

We consider the following question on the relationship between the asymptotic behaviours of Boolean networks and their regulatory structures: does the presence of a cyclic attractor imply the existence of a local negative circuit in the regulatory graph? When the number of model components n verifies n ≥ 6, the answer is known to be negative. We show that the question can be translated into a B...

The binding of purified 131I-3, 3', 5'-triiodothyronine (reverse T3) (rT3) to normal human serum components was investigated by a radioimmunoelectrophoretic technique. When anti-whole human serum was used, five distinct arcs of radioactivity were observed. Evidence was obtained that five of these radioactive arcs were not artifacts, but were due to components binding rT3. From the radioimmunoel...

the aim of the present study was to identify dimensions and dimensions and components of improving the educational quality of graduate students (master). the statistical population included all faculty and students of islamic azad university, science and research in the city of bushehr. the sample size in accordance with the morgan table was estimated about 201 faculties and 351 students, and t...

one of the most newest concepts in the field of positive organizational scholarship (pos) is the concept “thriving at work”. thriving at work is realized when people experience learning and vitality simultaneously while doing their job tasks. if jobs are designed so that people feel thriving, organizations can exploit its positive consequences. one of the motivational approaches to job design i...

BACKGROUND Direct/ measurement of work activities is costly, so researchers need to distribute resources efficiently to elucidate the relationships between exposures and back injury. METHODS This study used data from full-shift electromyography (EMG; N=133) to develop three exposure metrics: mean, 90th percentile and cumulative EMG. For each metric, the components of variance were calculated ...

Licorice is one of the most generally used herbal medicines in the world; however, wild licorice resources have decreased drastically. Cultivated Glycyrrhiza uralensis Fischer are the main source of licorice at present, but the content of main active components in cultivated G. uralensis are lower than in wild G. uralensis. Therefore, the production of high-quality cultivated G. uralensis is an...

The Saccharomyces cerevisiae SWI1, SWI2 (SNF2), SWI3, SNF5, and SNF6 gene products play a crucial role in the regulation of transcription. We provide here direct biochemical evidence that all five SWI/SNF polypeptides are components of a large multisubunit complex. These five polypeptides coelute from a gel-filtration column with an apparent molecular mass of approximately 2 MDa. The five SWI/S...
