Electrically conductive materials capable of substantial elastic stretch and bending are needed for such applications as smart clothing, flexible displays, stretchable circuits, strain gauges, implantable devices, high-stroke microelectromechanical systems, and dielectric elastomer actuators. A variety of approaches involving carbon nanotubes (CNTs) and elastic polymers have been suggested for ...
In order to reduce pollutant emissions from gas turbines, premixed combustion offers an attractive solution. However, in practical cases, the quality of the mixing may be difficult to assess and one need techniques to actually measure the local and instantaneous ratio between fuel and oxidizers. To provide such data, a technique was used that uses a Nd:YAG laser, focused through a spherical len...
Proc. Intl. Soc. Mag. Reson. Med. 22 (2014) 0482. Fig.1 The 1 H-MRS voxel included right and left posterior middle frontal gyrus. Introduction: Vascular Cognitive Impairment No Dementia (VCIND) is introduced to identify the earliest stage of cognitive decline associated with vascular disease, which does not meet dementia criteria but with an increased risk of death and institutionalization. Ear...
Introduction: Modification of the PULSAR technique [1] by use of a non-selective background suppression inversion pulse along with 3D-Turbo Field EPI (TFEPI) acquisition, labeled BSIR-3D-PULSAR, provides whole brain perfusion imaging in about five minutes. Furthermore, use of flip angle modulation reduces blurring when using centric-ordered slice encoding (along kz) followed by a single-shot gr...
مقدمه گیاهان پیوسته در معرض مجموعه ای از عوامل محیطی تنش زا قرار می گیرند که این عوامل تنش زا بسیاری از جنبه های ژنتیک و زیست مولکولی گیاه را تحت تاثیر خود قرار می دهند. در این بین شوری (nacl ,cacl2)، خشکی از مهمترین عوامل تنش زای محیطی به حساب می آیند. برای مقابله با این شرایط، گیاه باید قادر به درک، پاسخ دهی و سازگاری نسبت به این تغییرات محیطی باشد. مسیر signal transduction و ژن های مربوط به ...
Introduction: Dynamic changes in cardiac structure and function are usually examined by real-time imaging techniques such as angiography or echocardiography. Recently, MRI has proven many advantages compared with these established cardiac imaging modalities. Many techniques have been proposed for real-time interactive cardiac MR imaging [1]. However, most of these techniques are limited to only...
OBJECTIVE The objective of this analysis is to determine the effectiveness of solid organ transplantation in persons with end stage organ failure (ESOF) and human immunodeficiency virus (HIV+) CLINICAL NEED CONDITION AND TARGET POPULATION Patients with end stage organ failure who have been unresponsive to other forms of treatment eventually require solid organ transplantation. Similar to pers...
Introduction Most of the nuclear imaging systems require the use of a gamma (γ)-ray radiation shield to attenuate a stream of γ-rays so that only those traveling in a specified direction are allowed through and to absorb the scattered γ-rays from out of interest regions [1-2]. To meet those requirements, a γ-ray radiation shield is usually made out of lead (Pb) or some other high Z material suc...
A. Kido, T. Koyama, M. Kataoka, A. Yamamoto, S. Umeoka, S. Fujii, T. Saga, K. Togashi Kyoto University, Kyoto, Kyoto, Japan Introduction Uterus exhibits impressive hemodynamic change during menstrual cycle phases. During menstrual phase, prostaglandins are at their highest concentration (1). It induces uterine myometrial contractions and lead to decrease local uterine blood flow (2). Uterus als...
The use of 3-D Computer-aided Design (CAD) systems in engineering design and manufacturing has popularized the concept of the virtual product database. Product Data Management (PDM) and similar computer-based information management tools have increasingly been implemented to help manage this product database. Just as 3-D modeling is becoming an important component of the engineering graphics cu...
