Waste fibers produced from manufacturing processes are a byproduct commonly deposited in storing yards and/or landfills and thus results in many serious environmental problems in Iran. If these waste materials could be advantageously put to practical use in any application, it would reduce the burden on the environment and landfills. This paper compares the performance of the stone matrix aspha...

There are two different ways of using SMA wires as actuators for shape control of flexible structures; which can be either embedded within the composite laminate or externally attached to the structure. Since the actuator can be placed at different offset distances from the beam, external actuators produce more bending moment and, consequently, considerable shape changes with the same magnitude...

dissection of the internal carotid artery (ica) is a rare condition that accounts for a significant proportion of ischemic strokes in young adults. iatrogenic dissection as a complication of neurointerventional procedures is a traumatic dissection which has been reported relatively rare in the literature. in this report, a case of dissection of the ica is reported that was caused by repetitive ...

BACKGROUND AND PURPOSE Some patients who undergo surgical resection of portions of the supplementary motor area (SMA) have severe postoperative motor and language deficits, whereas others have no deficits. We tested the hypothesis that in some patients with lesions affecting the SMA, the contralateral SMA exhibits some of the activation normally associated with the ipsilateral SMA. METHODS Fu...

Guaranteeing the use of Shape Memory Alloys (SMA) in mitigation of extreme load effects requires a deep study of the SMA behavior according to the specific requirements of the application. In particular, for a storm is necessary more than one million of working cycles. It is applied to two realistic cables in ELSA (JRC-Ispra, Italy) and in IFSTTAR (old LCPC in Nantes, France). The measurements ...

The right hepatic artery is an important arterial supply to lobe of the liver. And knowledge normal anatomy and anatomical variations essential perfume, will minimize morbidity, also help decrease number complications hepatobiliary surgery. This study was conducted on eleven human cadavers, which were obtained from routine autopsies at dissection room Anatomy Department. During cadaveric livers...

This report describes a new finding regarding language-Supplementary Motor Area (SMA) in language processing using robust clinical protocols i.e. word generation (WG) and sentence generation (SG). This is a retrospective study on 7 patients referred for fMRI for preoperative language mapping. Subjects ranged in age from 20 40 years (28.8 ± 7.3), mean ± SD. We quantified the dimensions of langua...

To date, hypoxia-inducible factor 1a (HIF-1a) and astrocyte elevated gene-1 (AEG-1) have been involved in the proliferation, migration and morphological changes of vascular smooth muscle cells. However, the potential relationship of HIF-1a-AEG-1 pathway in human aortic smooth muscle cell (HASMC) has not been reported. In the present study, in-vitro assays were utilized to explore the potential ...

A 46-year-old man with a previous history of smoking (20 cig./day) was referred because of recurrent episodes of sudden high periumbilical abdominal pain. Upon examination, pain in the periumbilical region was found without peritoneal irritation sings. Blood pressure raised to 180/71 mm Hg. Hemogram, biochemistry, and venous blood gas analysis were strictly normal. On abdominal angio-TC (Fig. 1...

The purpose of this study was to investigate whether local mechanisms of blood flow autoregulation mediate vasoconstriction during the early development of renal hypertension. Anesthetized rats were instrumented with Doppler flow probes on the celiac (CA), superior mesenteric (SMA), and renal arteries to measure flow velocity in these vessels. Acute two-kidney, one clip renal hypertension was p...
