Bending instabilities of elastic tubes
(2002)The present paper examines instabilities of long thin elastic tubes. Both initially straight and initially bent tubes are analyzed under in-plane bending. Tube response, a combination of ovalization instability and bifurcation ... -
The berth allocation problem with stochastic vessel handling times
(2013)In this paper, the berth allocation problem with stochastic vessel handling times is formulated as a bi-objective problem. To solve the resulting problem, an evolutionary algorithm-based heuristic and a simulation-based ... -
beta-Lactoglobulin improves liposome's encapsulation properties for vitamin E delivery
(2014)Vitamin E (VE) or alpha-tocopherol is the major fat-soluble antioxidant in the human body. It is a sensitive, easily oxidized in the air, molecule, so it must be protected from pro-oxidant elements which could affect its ... -
BIOFUNCTIONALIZATION OF PET/SiO2 SURFACES FOR SINGLE MOLECULE EXPERIMENTS AND MEDICAL APPLICATIONS
(2011)PET/SiO2 layers were chemically modified to maintain immobilization of functional single molecules. GFP molecules provide an ideal system due to their stability and intrinsic fluorescence. GFP in vivo biotinylated within ... -
Bortezomib Downregulates MGMT Expression in T98G Glioblastoma Cells
(2013)The efficacy of treatment for glioblastoma multiforme is currently limited by the development of resistance, particularly, but not exclusively, due to the expression of the DNA repair enzyme O6-methylguanine methyltransferase ... -
Buckling and post-buckling of long pressurized elastic thin-walled tubes under in-plane bending
(2006)The present paper focuses on the structural stability of long uniformly pressurized thin elastic tubular shells subjected to in-plane bending. Using a special-purpose non-linear finite element technique, bifurcation on the ... -
Buckling of High-Strength Steel Cylinders Under Cyclic Bending in the Inelastic Range
(2014)The present paper examines the structural behavior of elongated steel hollow cylinders, referred to as tubes or pipes, subjected to large cyclic bending, through a rigorous finite element simulation. The bent cylinders ... -
Buckling of Thin-Walled Long Steel Cylinders Subjected to Bending
(2011)The present paper investigates structural response and buckling of long unstiffened thin-walled cylindrical steel shells, subjected to bending moments, with particular emphasis on stability design. The cylinder response ... -
Bully/victim problems and their association with psychological constructs in 8-to 12-year-old Greek school children
(2000)The aim of the present study was to replicate some of the already existing findings regarding the assessment of bully/victim problems in a sample of Greek primary school pupils using the Bullying Behaviour Scale and the ... -
Capacity and Stable Throughput Regions for the Broadcast Erasure Channel With Feedback: An Unusual Union
(2013)We consider a source node broadcasting to two receivers over a general erasure channel with receiver feedback. We characterize the capacity region of the channel and construct algorithms based on linear network coding ... -
Competitive Inhibition of Human Poly(A)-Specific Ribonuclease (PARN) by Synthetic Fluoro-Pyranosyl Nucleosides
(2009)Poly(A)-specific ribonuclease (PARN) is a cap-interacting deadenylase that mediates, together with other exonucleases, the eukaryotic mRNA turnover and thus is actively involved in the regulation of gene expression. ... -
Convex Approximation Algorithms for Back-Pressure Power Control
(2012)Throughput-optimal multihop wireless network operation entails a key physical-layer optimization problem: maximizing a weighted sum of link rates, with weights given by the differential queue backlogs. This emerges in joint ... -
Deflection of a liquid metal jet/drop in a tokamak environment
(2014)The interaction of a liquid gallium jet with plasma has been investigated in the ISTTOK tokamak. The jet was observed to remain intact during its interaction with plasma, within a certain length beyond which drop formation ... -
Development and Evaluation of a Phospholipid-sterol-protein Membrane Resembling System
(2015)The development and evaluation of a phospholipid-sterol-protein membrane resembling system containing beta-lactoglobulin (beta-Lg) has been studied. Liposomes have been successfully employed for the protection, controlled ... -
Differences in chemical, microbial and sensory quality parameters of the marinated ascidia Microcosmus sabatieri Roule, 1885 during storage at 6 degrees C under vacuum conditions
(2008)Chemical, microbial and sensory quality aspects of the marinated ascidia Microcosmus sabatieri Roule, 1885, were examined over a 150-day period at 6 degrees C, under vacuum and air (control) packaging conditions using three ... -
Effect of channel width on the primary instability of inclined film flow
(2010)A procedure is developed to detect the onset of interfacial instability in inclined film flows (with estimated accuracy better than 5%) and is used to show that the finite width of experimental channels stabilizes the ... -
The effect of co-dopant addition on the properties of Ln(0.2)Ce(0.8)O(2-delta) (Ln = Gd, Sm, La) solid-state electrolyte
(2008)The present work aims at the investigation of Ln(0.2)Ce(0.8)O(2-delta) (where Ln = Sm, La, Gd) structural and electrical properties when in the Ln sub-lattice, Ba2+ and Sr2+ with ionic radii 1.42 and 1.26 angstrom, ... -
Effect of dietary olive leaves (Olea europaea L.) on lipid and protein oxidation of refrigerated stored n-3-enriched pork
(2014)The objective of this study was to evaluate the effect of dietary olive leaves versus -tocopheryl acetate on lipid and protein oxidation of raw and cooked longissimus dorsi muscle from pigs fed diets supplemented with fish ... -
Effect of dietary oregano oil and alpha-tocopheryl acetate supplementation on iron-induced lipid oxidation of turkey breast, thigh, liver and heart tissues
