The "RapidTool" Short Run (SR) Tooling Process using the Copper Polyamide material provides a route to mold inserts for injection molding made directly in the Selective Laser Sintering machine. The STL files for the mold inserts are shelled and conformal cooling lines and ejector pin guides are added before SLS processing. Sintering of the material in the SLS machine provides quick metal/plasti...

In this paper, we present a multiresolution approach for the inspection of local defects embedded in homogeneously textured surfaces. It is based on an efficient image restoration scheme using the wavelet transforms. By properly selecting the smooth subimage or the combination of detail subimages at different resolution levels for image reconstruction, the global repetitive texture pattern can ...

Introduction: Skin photoaging can be treated with ablative therapies that may cause immunological changes to the skin. Objective: To evaluate the results of chemabrasion in the treatment of perioral wrinkles and the change in number of Langerhans cells. Material e methods: Application of 35% trichloroacetic acid followed by manual dermabrasion using waterproof sandpaper in 12 female patients wi...

Correspondence: Cem Yasar Sanhal e-mail: cemsanhal@ yahoo.com Objective. To compare the efficacy of five adhesions barrier products with a control group in a rat model. Methods. In this randomized controlled animal study, standardized lesions on parietal peritoneum of rats were created by sandpaper and three interrupted sutures. Afterwards, the lesions were treated with Seprafilm, Interceed, Pr...

henbane hyoscyamus reticulatus l. is a plant species in solanaceae family that seeds hardly germinate because of seed dormancy. in order to determine the best methods for seed dormancy breaking in henbane, a experiment was conducted as a completely randomized design with three replications. the treatments included moist pre-chilling (at 4 °c) for 7, 14, 21 and 28 days, combined treatment of gib...

Sol-gel coatings provide environmentally friendly surface protection for metals and can replace toxic pre-treatments such as those based on hexavalent chromium metal alloys. This project ultimately aims to develop silica-based organic–inorganic sol-gel derived thin film possessing anti-corrosion anti-fouling properties aluminium alloy substrates. As with any coating, sample preparation plays a ...

Biofilm heterogeneity and adaptability complicates efforts to link biofilm structural mechanical properties frictional drag. As a result, rigid structures are typically used as the benchmark for studying biofilm-associated Elastomeric sandpaper replicas were generated be model systems investigating effect of roughness elasticity on drag, over Reynolds number range approximately 2.0 × 104 5.2 Re...

Previous studies on adaptation of fingertip forces to local friction at individual digit-object interfaces largely focused on static phases of manipulative tasks in which humans could rely on anticipatory control based on the friction in previous trials. Here we instead analyze mechanisms underlying this adaptation after unpredictable changes in local friction between consecutive trials. With t...
