One new species of Riethia Kieffer, Riethia manauara n. sp., is described and figured as male, pupa and larva. The generic diagnosis for pupae and larvae are emended. The specimens were collected from water systems in the Amazon Rainforest in northern Brazil.

Bearingless switched reluctance motor (BSRM) has the advantages of high integration and low loss, is especially suitable for flywheel batteries. In order to enhance reliability fault tolerance ability BSRM, a novel dual-channel BSRM proposed in this paper. This combined merits magnetic bearing, can realize fault-tolerant operation. The scalloped rotor poles are evenly distributed on inner outer...

Statistically distinguishing density-dependent from density-independent populations and selecting the best demographic model for a given population are problems of primary importance. Traditional approaches are PBLR (parametric bootstrapping of likelihood ratios) and Information criteria (IC), such as the Schwarz information criterion (SIC), the Akaike information criterion (AIC) or the Final p...

Dual-stator brushless doubly fed generator (DSBDFG) is a novel applied for wind power generation, and the electromechanical energy conversion between stator rotor realised by magnetic field modulation of special structure. Therefore, design critical to improve performance DSBDFG. In this study, different structures are compared analysed, position non-magnetic ring determined. order reduce compu...

Pest des petits ruminants (PPR) is one of the important viral diseases of goats and sheep. The viral agent of PPR, Small ruminant morbillivirus (SRM), has been shown to infect several species among domestic and wild ruminants. In order to investigate the occurrence of SRM infection in Water Buffalo (Bubalus bubalis), blood samples were collected from 150 buffaloes (98 males, 52 females) referre...

tip leakage loss introduces major part of losses of the rotor in axial gas turbines. therefore, the rotor blade tip has a considerable effect on rotor efficiency. to understand the flow physics of the rotor tip leakage, we solve the flow field for different tip platforms (passive flow control) and by considering coolant tip injection (active flow control). various blade tip configurations such ...

In this paper, dual-rotor permanent magnet induction motor(DRPMIM) is studied to improve performance of usual induction motor(IM). Two-dimensional finite element model for DRPMIM is established by Maxwell Ansoft software, and electromagnetic characters of that was analyzed.Based on the rotating coordinate system, the mathematical model concerning DRPMIM, performance curves under the different l...

Abstract This paper describes the performance of a Solar PV-powered switched reluctance motor with low torque ripple in electric vehicle applications. The prominence motors has become significant industry, because its ineradicable characteristics like simple structure, absence rotor windings, less maintenance and self-starting capability. However, limitation SRM is high nonlinear characteristic...

Considering the significant magnetic saturation and the double salient poles of Switched Reluctance Motor (SRM), this paper presents a new method combining the Rapid Nonlinear Simulation Method with the Equivalent Magnet Circuit Analysis Model, which can make the accuracy and rapidity of the calculation of the performance of SRM achieved. This paper also presents a model of SRM, implements the ...

BACKGROUND The chance of a live birth after a diagnosis of secondary recurrent miscarriage (SRM) is reduced in patients who, prior to the miscarriages, gave birth to a boy and carry HLA class II alleles that efficiently present male-specific (H-Y) antigens to the immune system. Information about obstetric complications in births prior and subsequent to the SRM diagnosis is limited. The relation...
