The switched reluctance motor is a simple and robust machine, which has found application over a wide power and speed ranges in different shapes and geometries. This paper introduces a new configuration for a two phase unidirectional switched reluctance motor/field assisted generator. The proposed novel motor/generator consists of two magnetically independent stator and rotor sets (layers), whe...

Microtubules mediate mitochondrial distribution in the yeast Schizosaccharomyces pombe and many higher eukaryotic cells. In higher eukaryotes, kinesin motor proteins have been shown to transport mitochondria along microtubules, but the nature of the mitochondria-microtubule interactions in S. pombe has not been explored. By time lapse, total internal reflection fluorescence microscopy, or spinn...

The present study was designed to determine the contribution of cross-sectional area ski poles (Sp) total aerodynamic drag during alpine skiing. At three different wind speeds in a tunnel, 10 skiers assumed typical skiing postures (high, middle, and tuck), their frontal assessed with force plate area, along that poles, determined by interactive image segmentation. data collected were utilized e...

This paper presents analysis and comparative study of a novel high-torque three-phase switched reluctance motor (SRM) with magnetically isolated stator segments. In the proposed SRM, each segment has a concentric winding located on the center body of it and two diametrically opposite windings which form the motor phase. There are four salient poles in the stator segment. Two of them share their...

This article explores the relational and moral aspects of perception class structure identifications by young people in objectively vulnerable labour market conditions Poland Germany. Drawing on 123 biographical interviews with both countries, it demonstrates that precarious Poles Germans tend to identify themselves against ‘middle class’ – understood variously two countries attribute sources e...

Spindle positioning is believed to be governed by the interaction between astral microtubules and the cell cortex and involve cortically anchored motor protein dynein. How dynein is recruited to and regulated at the cell cortex to generate forces on astral microtubules is not clear. Here we show that mammalian homologue of Drosophila Pins (Partner of Inscuteable) (LGN), a Gαi-binding protein th...

Centrioles and basal bodies (CBBs) are microtubule-rich cylindrical structures that nucleate and organize centrosomes and cilia, respectively. Despite their apparent ninefold rotational symmetry, the nine sets of triplet microtubules in CBBs possess asymmetries in their morphology and in the structures that associate with them. These asymmetries define the position of nascent CBB assembly, the ...

What mechanisms ensure that temporal and spatial aspects of mitosis are properly coordinated? Part of the answer to this important question emerged from work published recently, which established that a connection between cell cycle progression and the large coiled-coil protein NuMA is key. The mitotic spindle must be positioned accurately during metaphase and anaphase to ensure that the result...

Haploidization of the genome in meiosis requires that chromosomes be sorted exclusively into pairs stabilized by synaptonemal complexes (SCs) and crossovers. This sorting and pairing is accompanied by active chromosome positioning in meiotic prophase in which telomeres cluster near the spindle pole to form the bouquet before dispersing around the nuclear envelope. We now describe telomere-led r...
