In this study, a total of 6 different composites were obtained by adding 5%, 10% and 15% chopped aramid fiber reinforcement in mm dimensions to each the polypropylene polyethylene matrix elements under same production method conditions. The materials mixed using extrusion then formed into plates press molding technique. Tensile charpy tests these performed their mechanical properties examined. ...

Spatially regulated transcription of the pipe gene in ventral cells of the Drosophila ovary follicle cell epithelium is a key event that specifies progeny embryo dorsal-ventral (DV) polarity. pipe encodes ten putative protein isoforms, all of which exhibit similarity to vertebrate glycosaminoglycan-modifying enzymes. Expression of one of the isoforms, Pipe-ST2, in follicle cells has previously ...

Mohamed Rahayem (2010): Segmentation and fitting for Geometric Reverse Engineering Processing data captured by a laser profile scanner mounted on an industrial robot. Örebro studies in Technology 37, 102 pages. Geometric Reverse Engineering (GRE) is the problem of creating CAD models of real objects by measuring point data from their surfaces. The GRE process is usually divided into four sub pr...

PURPOSE The B0 and B1+ maps required for calculation of the radiofrequency (RF) pulse of parallel transmission (pTx) are obtained in calibration scans; however, they may be affected by respiratory motion. We aimed to compare the reproducibility of B0 and B1+ maps and gradient echo (GRE) images of the brain scanned with pTx at 7T between free-breathing (FB) and breath-holding (BH) conditions dur...

INTRODUCTION Global oxygen extraction fraction (OEF) and cerebral metabolic rate of oxygen (CMRO2 ) were quantified in a test-retest study. Cerebral blood flow (CBF) data, required for CMRO2 estimation, were obtained using dynamic susceptibility contrast MRI (DSC-MRI). OEF and CMRO2 were quantified using two separate data sets, that is, conventional high-resolution (HR) gradient echo (GRE) phas...

Two newly identified, overlapping (1 bp) glucocorticoid response elements (GREs) at -759 and -773 bp in the promoter of the rat phenylethanolamine N-methyltransferase (PNMT; EC 2.1.1.28) gene are primarily responsible for its glucocorticoid sensitivity, rather than the originally identified -533-bp GRE. A dose-dependent increase in PNMT promoter activity was observed in RS1 cells transfected wi...

INTRODUCTION In fMRI, gradient-echo (GRE) single shot EPI allows a reasonable spatiotemporal resolution with robust functional activation. However, the combination of the long readout duration and echo time makes the method susceptible to image distortion, image blurring and signal dropout. Recently, balanced SSFP (bSSFP) fMRI has been proposed as an alternative method to compensate for these s...

As a new type of pipe, bimetallic composite pipe is widely used in various industries the chemical industry, because its internal and external tubes use different metals, so it can cope with variety working conditions. At present, application field mostly inner strong outer weak this has not been studied accordingly. In paper, theory expansion derived, complete set methods related parameter cal...

Background: Glioma-related epilepsy (GRE) is the most common presenting sign of patients with diffuse glioma. According to clinical experience, new-onset postoperative seizures can be observed even in without preoperative GRE. The current study mainly aimed explore risk factors those patients. In addition, prognostic value was also discussed. Methods: Data 313 GRE were retrospectively reviewed....
