Due to high heat generation within closely packed smart electronic devices, some efficient thermal management systems are required for their reliable performance, avoid overheating, long lifecycle and safety. In this study, a novel system based on forced air cooling having three airflow configurations is developed explore the characteristics of each configuration. A customized cavity designed h...

A tri-axial HTS power cable has been proposed and developed to reduce the number of HTS wires because it has copper shield instead of HTS shield. However, it has a drawback which is an inherent imbalance problem due to an asymmetry configuration in the cable. The authors designed a 22.9 kV/50 MVA class tri-axial HTS cable. The inherent imbalance problem of the three-phase currents in the tri-ax...

REASON FOR PERFORMING STUDY Analysis was performed to examine a method for refining the preoperative prognosis for horses that had surgery to remove apical fractures of the proximal sesamoid bones (PSBs). OBJECTIVES To determine if: 1) there was a difference in size or configuration of apical fractures between the different anatomical locations of the PSBs, which have been shown to affect the...

Context. The MHD instabilities can generate complex field topologies even if the initial field configuration is a very simple one. Aims. We consider the stability properties of magnetic configurations containing a toroidal and an axial field. In this paper, we concentrate mainly on the behavior of non-axisymmetric perturbations in axisymmetric magnetic configurations. Methods. The stability is ...

Nickel(II)-xylylbicyclam is a potent anti-HIV agent and binds strongly to the CXCR4 co-receptor. We have investigated configurational equilibria of Ni(II)-cyclam derivatives, since these are important for receptor recognition. Crystallographic studies show that both trans and cis configurations are readily formed: [Ni(cyclam)(OAc)(2)] x H(2)O adopts the trans-III configuration with axial monode...

Collagen plays an important role in the response of the arterial wall to mechanical loading and presumably has a load-bearing function preventing overdistension. Collagen configuration is important for understanding this role, in particular in mathematical models of arterial wall mechanics. In this study a new method is presented to image and quantify this configuration. Collagen in the arteria...

We use molecular mechanics simulations with the tight-binding potential to study local and global instabilities in initially defect-free nanosize rectangular prismatic specimens of gold deformed in tension/ compression and simple tension/compression. Whereas in simple tension/compression atoms on end faces are constrained to move axially but are free to move laterally and the cross-sectional di...

introduction: the aim of this study was to evaluate the root canal morphology of mandibular first and second molars using cone-beam computed tomography (cbct) in northern iranian population and also to indicate the thinnest area around root canals. methods and materials: we evaluated cbct images of 154 first molars and 147 second molars. by evaluating three axial, sagittal and coronal planes of...
