Relationships between MIBANT bend angles and selected material properties of pallet fasteners
… to relate the dynamic yield strength and MIBANT bend angle of driven steel fasteners. Static yield strength values for pallet nails were found to values (p > 0.0001 be linearly related to the dynamic 2 and R² = 0.950) and hence MIBANT bend angles. Static yield strength values were also related to …

Effects of Friction Stir Welding on Polymer Microstructure
… extruded polypropylene sheet. Three-point bend tests were used to determine the ultimate flexural strength and coincident strain. The maximum bend angle before failure was used to label the welds as "good or bad." An optical microscope capable of cross polarization was used to examine and …

Bending Of Metallic Thin Foil Via High Energy Pulsed Laser Peening
… ratio, and number of scan tracks on bend angle, is discussed. Mechanisms ofLPF are reviewed by elucidating the mechanics of convex and concave curvature.Particularly, the Stress Gradient Mechanism (SGM) and the Stress Bending Mechanism(SBM), are modeled. In addition, the effect that …

DNA target site recognition by the Ll.LtrB group II intron RNP
… must be bent. I have dissected the role of DNA bending in the intron mobility pathway and found that the DNA is bent at two progressively larger angles as the reaction proceeds. The predominant bend angle at earlier time points places the bottom-strand DNA cleavage site at the protein …

STUDYING THE INTERACTION OF CANCER AND THROMBOSIS THERAPEUTICS WITH PROTEIN AND DNA
… We found that cisplatin induces a 36º bend angle for a cisplatin-GG adduct and 0 - 19º for a cisplatin-AG adduct. Overall DNA flexibility did not change due to these interactions with a single cisplatin molecule, but DNA softens around the damage site. The intercalating drug Pt-Acramtu …

Printing conductive ink tracks on textile materials
… printed was tested by introducing strain via bending test to determine its performance in changing resistance when bent. It was found that the resistance obtained from manual method and single layer conductive ink track by silkscreen process were as expected. But this is a different case for …

Unusual molecular architectures in liquid crystal and polymer chemistry
… Chapter Two is on the effects that changing the bend angle and/or lateral dipole have upon the phase behavior of these compounds. We found that the thiophene-based mesogens with the largest lateral dipoles display the most stable liquid crystalline phases. We believe that this effect is due to …

Characterization and optimization of photonic devices fabricated using femtosecond laser micro-matching
… of the loss per unit length, per unit bend angle, and per re-write of the waveguides a structured set of guidelines for device fabrication for our particular setup can be made. The second aim of this thesis is the characterization of the photonic devices fabricated and demonstrated by …

Three-dimensional nonequilibrium viscous shock-layer flows over complex reentry vehicles
… spherecones, straight. and bent mul ticonics at angle-of-attack has been developed. The method used is the viscous shock-layer approach- for nonequilibrium, multi-component ionizing air. A seven species chemical reaction model with single ionizing species and an eleven species chemical reaction …

Mathematical modelling and optimisation of the formulation and manufacture of aggregate food products
… a straight pipe, a rig consisting two 45° bends and one with 90° bend. It was observed that the least amount of breakage occurred in the straight pipe while the most breakage occurred at 90° bend pipe. Moreover, lower levels of breakage were observed in two 45° bend pipe than the 90° bend …

A Computational Fluid Dynamics based model that predicts wall shear stress in CANDU outlet feeder pipes
… the maximum wall shear stress on the first bend of a particular feeder pipe considering the fluid Reynolds number, the bend angle and the linear length from the grayloc hub to the first bend. The model is developed using the wall shear stress distribution results generated by Computational …

Evaluation of the joint performance estimates within the PDS durability procedure
… and fastener stiffness as measured by the MIBANT bend angle. The observed affect of changes in fastener stiffness on pallet diagonal rigidity was found to be accurately reflected in the computed F(2) values. The observed affect of changes in the number of fastener couples on pallet diagonal …

Syntheses, properties, and reactions of transition metal complexes of di(tert-butyl)amide and 2,2,6,6-tetramethylpiperidide
… that the Mn and Fe compounds have linear N-M-N angles, whereas the Co and Ni compounds are bent. In addition, the Fe and Co compounds have large orbital contributions to their magnetic moments, whereas the Mn and Ni compounds do not. In order to understand these properties, the electronic …
