This paper conducts a comparison study using KES-FB and PhabrOmeter to measure 58 selected warp knitted fabric hand properties. Fabric samples were selected and measured by both KES-FB and PhabrOmeter. Results show differences between these two measurement methods. Smoothness and stiffness values obtained by KES-FB were found significant correlated (p value = 0.003 and 0.022) to the PhabrOmeter...
Advanced aging, vascular dysfunction, and nitric oxide (NO) bioavailability are recognized risk factors for Alzheimer's disease (AD). However, the contribution of AD, per se, to this putative pathophysiological mechanism is still unclear. To better answer this point, we quantified cortical perfusion with arterial spin labeling (PVC-CBF), measured ultrasound internal carotid (ICA), and femoral (...
background: foreign body aspiration (fba) of tracheobronchial trees is accidental evidence in children. it occurs the most common in less than 3-year age old. diagnosis of inhaled fb is a dilemma in the pediatric, particularly in delayed or missed conditions. the aim of the study assessed the clinical features and rigid bronchoscopic finding of aspirated fb in tracheobronchial trees of children...
Let $R$ be a commutative Noetherian ring and let $fa$, $fb$ be two ideals of $R$ such that $R/({fa+fb})$ is Artinian. Let $M$, $N$ be two finitely generated $R$-modules. We prove that $H_{fb}^j(H_{fa}^t(M,N))$ is Artinian for $j=0,1$, where $t=inf{iin{mathbb{N}_0}: H_{fa}^i(M,N)$ is not finitelygenerated $}$. Also, we prove that if $DimSupp(H_{fa}^i(M,N))leq 2$, then $H_{fb}^1(H_{fa}^i(M,N))$ i...
It is known that, within the service time distribution class DHR, the FB discipline minimizes the mean delay in the M/G/1 queue among all work-conserving and non-anticipating service disciplines. It is also believed that a similar result is valid within a more general distribution class IMRL. However, we point out a flaw in the existing proof of this latter result that cannot be overcome. Moreo...
In this study the effect of activating fluxes on the penetration depth, microstructure and microhardness of AISI316L austenitic stainless steel were evaluated by three TIG process variations (TIG, A-TIG and FB-TIG) and the results were compared together.. After selecting the optimal flux in the second stage, the effect of that on the penetration depth, microstructure and weld microhardness of ...
Current findings suggest a role for the angiotensin II (Ang II) signalling pathway in generation of reactive oxygen species and diabetes-induced cardiac complications. In this study we aimed to investigate the effect of angiotensin II type 1 (AT 1 ) receptor blockage on some antioxidant enzy mes such as glucose-6-phosphate dehydrogenase (G6PD), 6-phoshogluconate dehydrogenase (6PGD), glutathion...
This study examines the process and effects of using facebook (FB) to locate and re-contact study participants targeted for follow up in a longitudinal study of adult methamphetamine users (N = 649). A follow-up interview was conducted in 2009-11 approximately 8 years after previous study participation. Our paper describes re-contact efforts involving FB, including IRB regulatory issues and the...
Introduction: Foreign Body Aspiration (FBA) represents a life-threatening emergency .It occurs primarily in children below 3 years. Generally, the most common aspirated FB is organic material such as nuts or beans. Sharp Foreign Bodies (FBs) are of particular concern to the attending clinician, because of their potential to perforate the air passage and cause possible complications. Here in, we...
