In this paper we discuss the effects on throughput and fairness of dynamic channel bonding (DCB) in spatially distributed high density (HD) wireless local area networks (WLANs). First, we present an analytical framework based on continuous time Markov networks (CTMNs) for depicting the phenomena given when applying different DCB policies in spatially distributed scenarios, where nodes are not r...
2-Dodecylcyclobutanone (2-DCB) is formed by the radiolysis of palmitic acid and is present at low part-per-million (approximately 0.1 g/g) levels in irradiated meat products. Recently, equivocal results obtained using a DNA strand breakage test, the Comet Assay, raised the possibility that 2-DCB could be a weak genotoxin. To more accurately assess 2-DCB’s potential genotoxicity, it was tested f...
Chlorobenzenes are the colourless liquid with an almond-like odour. The compound does not occur widely in nature, but it is one of those chemicals which are produced industrially in large amounts. They have many applications, such as intermediate products of the chemical and pharmaceutical industries and as biocides and additives [1]. Chlorination of chlorobenzenes in the presence of variety of...
Precise Point Positioning (PPP) has become a very hot topic in GNSS research and applications. However, it usually takes about several tens of minutes in order to obtain positions with better than 10 cm accuracy. This prevents PPP from being widely used in real-time kinematic positioning services, therefore, a large effort has been made to tackle the convergence problem. One of the recent appro...
BACKGROUND Phase III studies suggest that non-small-cell lung cancer (NSCLC) patients treated with cisplatin-docetaxel may have higher response rates and better survival compared with other platinum-based regimens. We report the final results of a randomised phase III study of docetaxel and carboplatin versus MIC or MVP in patients with advanced NSCLC. PATIENTS AND METHODS Patients with biops...
در این نوشتار مساله محاسبه ضریب شدت تنش برای یک ترک ساکن با در نظر گرفتن اثر تغییر شکل برشی در یک نمونه dcb مورد بررسی قرار گرفته است بدین منظور نمونه متشکل از دو تیر تیموشنکو در نظر گرفته می شود که در ناحیه تماسشان تکیه گاه الاستیک winkler قرار دارد. مسئله در حالت کلی مورد تحلیل قرار می گیرد. ولی در حالت خاصی که طول ناحیه پس از نوک ترک در مقیاس ارتفاع نمونه باشد. رابطه ساده و مختصری ارائه می گ...
To improve the ductility and seismic performance of a double coupling beam, authors applied polyethylene terephthalate (PET) sheet steel tube to form fiber-reinforced polymer (FRP)–concrete–steel double-skin tubular (DST) composite beams. A low-cyclic reversed experimental program was carried out which factored in member form, diameter, construction methods. The results indicate that energy dis...
1,2-, 1,3and 1,4-Dichlorobenzene (DCB) have been identified in at least 281, 175, and 330, respectively, of the 1,662 hazardous waste sites that have been proposed for inclusion on the EPA National Priorities List (NPL), respectively (HazDat 2005). However, the number of sites evaluated for these DCB isomers is not known. The frequency of these sites can be seen in Figures 6-1, 6-2, and 6-3. Of...
Delamination buckling and propagation analysis of honeycomb panels using a cohesive element approach
The cohesive element approach is proposed as a tool for simulating delamination propagation between a facesheet and a core in a honeycomb core composite panel. To determine the critical energy release rate (Gc) of the cohesive model, Double Cantilever Beam (DCB) fracture tests were performed. The peak strength (σc) of the cohesive model was determined from Flatwise Tension (FWT) tests. The DCB ...
The GTPase Arf1 is the major regulator of vesicle traffic at both the cis- and trans-Golgi. Arf1 is activated at the cis-Golgi by the guanine nucleotide exchange factor (GEF) GBF1 and at the trans-Golgi by the related GEF BIG1 or its paralog, BIG2. The trans-Golgi-specific targeting of BIG1 and BIG2 depends on the Arf-like GTPase Arl1. We find that Arl1 binds to the dimerization and cyclophilin...
