The aim of this paper is to present a new model for the linear induction motor (LIM), which is based on its equivalence with the asymmetrical rotary induction motor. The model uses the theory of positive, negative and zero sequence of symmetrical and asymmetrical components. Experimental and simulation procedures with a LIM prototype allowed the theoretical and experimental validation for this ...

Deformities in the child with cerebral palsy have been ascribed to muscle imbalance (Sharrard 1961) and increased tone (Pollock 1959) or to the type of cerebral palsy (Bobath and Bobath 1975). As far as we know, the position in which the child is nursed, especially during the first year of life, has not been considered as a cause of deformity. It is generally agreed that position in the postnat...

It is important to obtain structure-activity relationship (SAR) data across cationic lipids for the self-assembly and non-viral intracellular delivery of siRNA. The aims of this work are to carry out a SAR study on the efficiency of asymmetrical N,N-diacyl spermines in siRNA delivery and EGFP reporter gene silencing, with comparisons to selected mixtures composed of symmetrical N,N-diacyl sperm...

The ability of subjects to balance on narrow rails was measured during exposure to pure tones of 100. 260, 500, 1500, and 2500 Hz and a control condition. One group of subjects was presented the test stimulus at intensity levels of 95 dB (re 0.0002 dyne/cm) in the left ear and 75 dB in the right ear (asymmetrical exposure). The other group was presented the tones at a level of 95 dB in both ear...

This study was set out to shed light on the efficacy of pushed output directed by scaffolding on 41 (24 female and 17 male) upper-intermediate EFL learners’ speaking fluency and accuracy. A public version of IELTS speaking test was held to measure learners’ entrance behavior. Then, they were randomly assigned into symmetrical, asymmetrical, and control group. The experimental and control groups...

In this paper, an analytical method based on Modified Slab Method of analysis is presented to study the asymmetrical rolling process due to difference in work rolls radii, rolls speeds and interface frictions. The shear force imposed on material along the contact region is considered to be a function of the frictional factor and the roll gap geometry. Elastic-plastic with linear work hardening ...

Asymmetrical activity over the frontal cortex has been implicated in the experience and expression of emotions and motivations. Explanations of the research have suggested that relatively greater left frontal activity is associated with positive affect and/or approach motivation, and that relatively greater right frontal activity is associated with negative affect and/or withdrawal motivation. ...

A modification of spoligotyping with primers derived from the direct repeat (DR) and IS6110 sequences was used to identify IS6110 insertions in the DR locus of Mycobacterium tuberculosis clinical strains from the St. Petersburg area of Russia. Novel IS6110 insertions were identified: (i) in two epidemiologically unlinked Beijing family strains, an asymmetrical direct insertion in DR37; (ii) in ...

This paper presents a concept of voltage-vector in three-dimensional space vector modulation for four-leg active filter which are developed based on Euler angle rotation method, and its produces a skewed rod shape consisting of twelve-pairs of asymmetrical tetrahedron nonzero switching vector in which voltage-vector reference is determined by four-pairs of its tetrahedron. Voltage-vector refere...
