Bending instabilities of elastic tubes

Karamanos, S. A. (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 ...

beta-Lactoglobulin improves liposome's encapsulation properties for vitamin E delivery

Rovoli, M.; Gortzi, O.; Lalas, S.; Kontopidis, G. (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 ...

Buckling and post-buckling of long pressurized elastic thin-walled tubes under in-plane bending

Houliara, S.; Karamanos, S. A. (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 ...

Collapse of pressurized elastoplastic tubular members under lateral loads

Karamanos, S. A.; Eleftheriadis, C. (2004)

The present work examines the collapse of tubular members subjected to lateral (transverse) quasi-static loading in the presence of uniform pressure. In particular, it investigates pressure effects on the ultimate lateral ...

Distribution and stability of aflatoxin M-1 during production and storage of yoghurt

Govaris, A.; Roussi, V.; Koidis, P. A.; Botsoglou, N. A. (2002)

Yoghurt from cow's milk artificially contaminated with aflatoxin M-1 (AFM(1)) at levels of 0.050 and 0.100 g l(-1) was fermented to reach pHs 4.0 and 4.6. Yoghurt fermented to pH 4.6 was also used for preparing strained ...

THE EFFECT OF A TRADITIONAL DANCE TRAINING PROGRAM ON DYNAMIC BALANCE OF INDIVIDUALS WITH MENTAL RETARDATION

Tsimaras, V. K.; Giamouridou, G. A.; Kokaridas, D. G.; Sidiropoulou, M. P.; Patsiaouras, A. I. (2012)

Tsimaras, VK, Giamouridou, GA, Kokaridas, DG, Sidiropoulou, MP, and Patsiaouras, AI. The effect of a traditional dance training program on dynamic balance of individuals with mental retardation. J Strength Cond Res 26(1): ...

Evaluation study of a Navier-Stokes CFD aeroelastic model of wind turbine airfoils in classical flutter

Baxevanou, C. A.; Chaviaropoulos, P. K.; Voutsinas, S. G.; Vlachos, N. S. (2008)

This paper describes a new aeroelastic numerical model, which combines a Navier-Stokes CFD solver with an elastic model and two coupling schemes for the study of the aeroelastic behaviour of wind turbine blades undergoing ...

Exploiting wireless channel, state information for throughput maximization

Tsibonis, V.; Georgiadis, L.; Tassiulas, L. (2004)

We consider the problem of scheduling packets over channels with time-varying quality. This problem has received a lot of attention lately in the context of devising methods for providing quality of service in wireless ...

Interrelationship among and repeatability of seven stability indices estimated from commercial cotton (Gossypium hirsutum L.) variety evaluation trials in three Mediterranean countries

Baxevanos, D.; Goulas, C.; Tzortzios, S.; Mavromatis, A. (2008)

Multi-environment trial data are required, to obtain variety stability performance parameters as selection tools for effective cultivar evaluation. The interrelationship among seven stability parameters and their association ...
