Behaviour of continuously supported self-compacting concrete deep beams
… EC2 and Canadian Code (CSA23.3-04). The proposed effectiveness factor equations for the strut-and-tie model showed accurate predictions compared to the experimental results. The different equations of the effectiveness factor used in upper-bound analysis can reasonably be applied to the prediction …

ΚΑΤΑΛΥΤΙΚΑ ΚΑΙ ΗΛΕΚΤΡΟΚΑΤΑΛΥΤΙΚΑ ΦΑΙΝΟΜΕΝΑ ΣΕ ΗΛΕΚΤΡΟΧΗΜΙΚΑ ΣΤΟΙΧΕΙΑ ΣΤΕΡΕΟΥ ΗΛΕΚΤΡΟΛΥΤΗ ΥΨΗΛΗΣ ΘΕΡΜΟΚΡΑΣΙΑΣ
… REACTORS WAS DEVELOPED. IT WAS FOUND THAT THE EFFECTIVENESS FACTOR OF A CATALYTIC PARTICLE IN ATRICKLE BED REACTOR, CAN BE EXCHANGED BY A FACTOR OF 2 WHEN THE WETTING EFFICIENCY CHANGES FAST WITH TIME AS IT IS THE CASE IN THE PULSE- FLOW REGIME, COMPARED WITH THE EFFECTIVENESS OF THE PARTICLE …

Examining Perceptions of Crime and Disorder in A Rural University Setting
… of those surveys 655 students responded. A factor analysis using a varimax rotation was used to group similar variables into latent variables. Three factors emerged: (1) general perception of crime and disorder, (2) traffic congestion, and (3) alcohol and drug abuse. Various analytical …

Longitudinal shear resistance of steel and concrete composite beams
… literature, indicate that the existing reduction factor method employed in current design is not entirely appropriate. Failure of the new specimens with transverse decking was characterised by the formation of cones of concrete around the stud connectors. The shear transfer resistance of the studs …

Investigation of Torrefaction Process Parameters on Biomass Feed-Stock and CO2 Gasification of Torrefied and Pyrolysed Bio-char
… parameters such as effective diffusivity, effectiveness factor, and Diffusion limitation index (DLI) were calculated from the experimental data for both the char types.

Quantifying Air Distribution, Ventilation Effectiveness and Airborne Pollutant Transport in an Aircraft Cabin Mockup
… related to its airflow distribution, ventilation effectiveness and airborne pollutant transport. The experimental facility is a full-scale aircraft cabin mockup. A volumetric particle tracking velocimetry (VPTV) technique was enhanced by incorporating a self-developed streak recognition algorithm. …

Electronic band engineering: Titanium dioxide particulate layers for photocatalysis
… coefficients benefit the rate constant and effectiveness factor, but only to a certain point. For example, gas phase photoreactions do not benefit from band engineering. The intrinsic rate constant linearly influences the overall reaction rate. When the penetration depth of light is smaller …

Designer Porous Carbon Electrodes for Redox Flow Batteries
… explores mathematical frameworks to quantify the effectiveness factor of high surface electrocatalysts as functions of particle and reactant properties, applying both Tafel and Butler-Volmer kinetic descriptions to reaction-diffusion processes within a porous sphere. From this analysis, I identify …

Studies of Carbon Dioxide Methanation and Related Phenomena in Porous Catalysts
… Thiele moduli and the extents of error in both effectiveness factor and selectivity were quantified relative to one-dimensional sphere and slab analogues. The errors between 2-D and 1-D analogues were found to be most significant between Thiele moduli of ~0.25 and ~3. Hollow cylinder …

Behaviour of continuous concrete deep beams reinforced with GFRP bars
… were employed to assess the performance of the effectiveness factors suggested by the STMs of the American (ACI 318-2014), European (EC2-04) and Canadian (S806-12) codes as well as those factors recommended by the previous studies to predict the load capacities. It was found that these methods …
