A 14-year-old BMX driver suffered a blunt trauma towards the lateral neck (Fig. 1). A computed tomography (CT) angiography revealed a dye stop in the left subclavian artery with collateral blood flow (Fig. 2). Interventional catheterisation revealed a rupture. However, no peripheral pulse deficit was evident, and, therefore, no immediate vascular surgery was performed. www.elsevier.com/locate/e...

Packet and flow scheduling algorithms for WiMAX has been a topic of interest for a long time since the very inception of WiMAX networks. WiMAX offers advantages particularly in terms of Quality of service it offers over a longer range at the MAC level. In our paper, we propose two credit based scheduling schemes one in which completed flows distributes the left over credits equally to all highe...

Foreign direct investment (FDI) is a major factor in the globalization scenario. However, contrary to the core pro-market tenets of the economic school supporting globalization, the flows of FDI have grown side by side with a whole array of FDI subsidies dispensed by the “visible hand” of the state. Scholars have studied the links between FDI and economic growth and between subsidies and actual...

Fair queuing is a technique that allows each flow passing through a network device to have a fair share of network resources. Previous schemes for fair queuing that achieved nearly perfect fairness were expensive to implement: specifically, the work required to process a packet in these schemes was O(log(n) ), where n is the number of active flows. This is expensive at high speeds. On the other...

We describe the case of a 72-year-old man presenting with endocarditis and clinical signs of acute myocardial ischemia after biological aortic valve replacement. A comprehensive cardiac dynamic multislice spiral computed tomography demonstrated: (1) an endocarditic vegetation of the aortic valve; (2) a subvalvular leakage feeding a paravalvular pseudoaneurysm based on an aortic root abscess wit...

This paper proposes a simple, fair and efficient scheduler for wireless networks called Opportunity-based Deficit Round Robin (ODRR). In most schedulers proposed for wireless networks, when a flow encounters errors and uses the allocated resource inefficiently, it is compensated with a larger allocation at a later time to ensure fairness in the number of bytes transmitted successfully. The ODRR...

Objective . To assess the effect of external carotid artery (ECA) endarterectomy on regional cerebral blood flow, cognitive function, and quality life in patients with ICA occlusion. Materials Methods From 2019 to 2020 year, 14 operations were performed occlusion hemodynamically significant ECA lesion. patients, 12 men (85.7 %) 2 women (14.3 underwent resection ICA, common (CCA), ECA. All had a...

the objective of deficit irrigation is to increase water use efficiency by reducing of water quantity or wave off further irrigations that have not necessary. cotton plant is sensitive to irrigation timing and quantity through different growth stages. the field trail was conducted at hashemabad cotton research station (gorgan) to determine water consumption and cotton sensitivity to deficit irr...

In this study the regional cerebral blood flow (rCBF) pattern of three Mild Cognitive Impairment (MCI) subtypes was measured with SPECT in 60 patients (nineteen with an amnestic deficit, sixteen with disexecutive deficits, and twenty five with mild multidomain deficits) and compared with that of 15 healthy matched older adults. The amnestic MCI subgroup showed significant hypoperfusion in the l...
