Συμβολή της ηλεκτρονικής μικροσκοπίας σαρώσεως στη μελέτη ελαστοπλαστικών φαινομένων κατά τη θραύση των υλικών
… that the examinated materials (copper and Lexan) exhibited very different behavior as far as the above mentioned phenomena are concerned. In the case of Lexan an intense formation of a (oblongs) damaged ligament ahead of the crack-tip is observed. This ligament is of a Dugdale general type …

157nm F₂laser characterization and application to polymer ablation
… molecular weight polyethylene (UHMWPE), Lexan polycarbonate and CR-39 polymer have been investigated. The main priority was given to Lexan polycarbonate and CR-39 polymer as new potential materials to explore using this laser.A considerable component of the work is directed at gaining a …

Design of swimming fins to treat Patellofemoral Pain Syndrome
… Configurations of mock up fins, made from Lexan, were designed based off of a known dry land exercise that consisted of leg lifts with the feet turned out 45 degrees that work the Vastus Medialis. From the feedback of a swimmer, new design iterations were made to compensate for how a …

Measurements of Surface Displacements During Stress Wave Propagation in Opaque Solids Using Pulsed Laser Speckle Photography
… and holography. Results using Homalite 100 and Lexan are presented.

Experimental study of heat transfer and fluid flow in unsaturated porous media
… of homogeneous glass beads packed uniformly in a Lexan rectangular box. A cylindrical heat source was located horizontally in the middle region of the bed and the bed was heated to steady state conditions. Water was then introduced uniformly through square nozzles located over the fill material …

Interdigital dielectrometry based detection and identification of dangerous materials for security applications
… materials such as air, sand, sugar, salt, wood, Lexan, Teflon, and paper and later on actual shoes with cavities containing foreign materials show that the materials can be identified based on their complex dielectric properties as extracted from experimental data using an inverse parameter …

Design of Optical Measurements for Electrothermal Plasma Discharges
… that the assumption that the propellant Lexan is completely dissociated is a valid assumption, and that the ETFLOW results for electron temperature, density, and bulk plasma velocity match experimental values.

Ferrofluid flow and torque measurements in rotating magnetic fields
… measure this torque on the outer wall of a Lexan spindle that is attached to a viscometer, functioning as a torque meter. The spindle is immersed in a beaker of ferrofluid centered inside a 2-pole or 4-pole motor stator winding, creating uniform or nonuniform rotating magnetic fields, …

Comparing the distribution of pathogenic bacteria and common indicator microorganisms in biofilms on different surface types in an agricultural watershed in British Columbia (Canada)
… on river and slate rock, wood, sandpaper, and Lexan™ in Elk Creek (British Columbia, Canada) from December 2005 to April 2007. Faecal indicator concentrations and pathogen presence were evaluated using standard culturing and isolation methods. The results showed that both faecal indicators and …

Dense-phase pneumatic transport of cohesionless solids
… constructed . The pipe material is transparent lexan which allows for visual observation of the flow pattern. The particles used were a mixture of 95% white and 5% black polyethylene granules (particle diameter approximately 3 mm). The black particles were used to aid the visual observation of …

Use of the hole pressure data to obtain N1 at high shear rates for polymer melts
… for polystyrene (Styron-678) and polycarbonate (Lexan) melts. It was found that both the flow and stress fields are asymmetrically distributed about the slot centerline and that secondary flows exist in the upper part of the slot. However, no visible vortices was found for LOPE even though …

Theory and modeling of laser-driven flyer plate experiments to study explosives under a microscope
… targets of Pyrex and fused silica glasses, and Lexan and Plexiglas polymers, producing pressures in the target in the 5 - 20 GPa range. The simulations are compared to experimental results where the flyer velocity profile and the velocity profile imparted to the target material were measured …
