Air temperature regime in a forced ventilated greenhouse with rose crop
(2005)The use of forced ventilation for greenhouse cooling and air humidity regulation purposes has been expanded around Mediterranean area. The aim of the present study was the experimental investigation of the variables, as ... 
Analytical and numerical study of MHD natural convection in a horizontal shallow cavity with heat generation
(2014)A study is presented of twodimensional MHD natural convection flow in an internally heated horizontal shallow cavity in the presence of an external uniform vertical magnetic field. The main feature of the present flow is ... 
Aortic Function: From the Research Laboratory to the Clinic
(2012)For many years, much of the pioneering research on aortic function was carried out by a small group of investigators frequently working away from the clinical environment in the research laboratory. The evaluation of aortic ... 
Bayesian uncertainty quantification and propagation for discrete element simulations of granular materials
(2014)Predictions in the behavior of granular materials using Discrete Element Methods (DEM) hinge on the employed interaction potentials. Here we introduce a data driven, Bayesian framework to quantify DEM predictions. Our ... 
Blood velocity pulse quantification in the human conjunctival precapillary arterioles
(2010)Axial red blood cell velocity pulse was quantified throughout its period by high speed video microcinematography in the human eye. In 30 conjunctival precapillary arterioles (6 to 12 mu m in diameter) from 15 healthy humans, ... 
Computational phlebology: reviewing computer models of the venous system
(2013)Relatively little attention has been paid to the venous system and valves from a cardiovascular engineering perspective up to now. Given the involvement of venous valve haemodynamics in the development of deep vein thrombosis ... 
Direct numerical simulation of a heat removal configuration for fusion blankets
(2007)A series of direct numerical simulations (DNS) are performed to study the natural convection heat transfer between concentric cylinders at several Rayleigh and Hartmann numbers. The buoyant flow is driven by the temperature ... 
Dispersal ability in codling moth: markreleaserecapture experiments and kinship analysis
(2012)1 The present study focused on the dispersal patterns in the codling moth because such information is fundamental for determining the dynamics and genetics of the pest populations and for developing efficient management ... 
Effect of wall roughness on shear viscosity and diffusion in nanochannels
(2010)The effect of wall roughness on liquid argon shear viscosity and diffusion coefficient in nanochannels is studied by nonequilibrium molecular dynamics. Diffusion coefficient results are presented in terms of average values ... 
Efficiency of a pneumatic device in controlling cuff pressure of polyurethanecuffed tracheal tubes: a randomized controlled study
(2013)Background: The primary objective of this study was to determine the efficiency of a pneumatic device in controlling cuff pressure (Pcuff) in patients intubated with polyurethanecuffed tracheal tubes. Secondary objectives ... 
Film cooling predictions of simple and compound angle injection from one and two staggered rows
(2001)Typical filmcooling configurations of flat plates from one and two staggered rows of simple and compound angle injection holes are investigated using a threedimensional finite volume method and a multiblock technique, ... 
Formulation and stability analysis of rapidly convergent iteration schemes for the 2D linearized BGK equation
(2007)Various HN rapidly convergent schemes are proposed to speed up the slow convergence of the iterative solution of 2D linearized BhatnagarGrossKrook (BGK) kinetic equation containing up to the first moments of the ... 
THE IMPACT OF INSECT SCREENS AND VENTILATION OPENINGS ON THE GREENHOUSE MICROCLIMATE
(2008)The objective of this work was to experimentally investigate the influence of vent type (side, roof, or both) and of antiaphid insect screens on airflow, air temperature, and air vapor pressure deficit distribution in a ... 
Indentation of plastically graded substrates by sharp indentors
(2002)The present paper investigates the indentation of plastically graded substrates by sharp indentors. Contact analysis of plastically graded surfaces can be particularly useful in the design of loadbearing devices such as ... 
Integration of a Hydrological Model within a Geographical Information System: Application to a Forest Watershed
(2014)Watershed simulation software used for operational purposes must possess both dependability of results and flexibility in parameter selection and testing. The UBC watershed model (UBCWM) contains a wide spectrum of parameters ... 
Interrill erosion on cultivated Greek soils: modelling sediment delivery
(2006)For interrill erosion, raindropinduced detachment and transport of sediment by rainfalldisturbed sheet flow are the predominant processes, while detachment by sheet flow and transport by raindrop impact are negligible. ... 
Linear stability analysis and dynamic simulations of free convection in a differentially heated cavity in the presence of a horizontal magnetic field and a uniform heat source
(2006)The steady state and stability of twodimensional free convection flow in a square cavity is examined, in the presence of a uniform internal heat source and a uniform magnetic field that is perpendicular to gravity and ...
