in this paper, the accumulative channel-die compression bounding (accb) method is investigated as a new method of severe plastic deformation to produce nano-crystalline bulk metals on the basis of pressing in a channel mold. aluminum as one of the most usable metal in industry is processed using this method. analyzing the processed samples show that after four passes of accb method, the ultimat...

In this paper we introduce a blanket mold imprinting process to prevent complication of the fluid flow and difficulties in producing high pressure seals. Inchannel embedded metal lines were also fabricated within the channel allowing electrochemical detections of analytes. Electrochemical microfluidc device has been fabricated on the PET (Polyethylene Terephthalate) substrate by using imprintin...

Particle motion and capture in continuous steel casters were simulated using a Lagrangian trajectory-tracking approach, based on time-dependent flow fields obtained from large eddy simulations (Part I). A computation was first conducted on a water model of a full-scale standard slab caster, where measurements were available. It simulated the transport of 15,000 plastic particles, and their remo...

Abstract: During injection molding process, the mold temperature is one of the most important influences on the product quality. In this paper, the temperature of the core plate with the size of 100 mm × 100 m × 40 mm will be examined for different product sizes. Different types of heating and cooling channels are inserted in the core plate. The size of the plastic product will be changed from ...

This is a report of a unique finding in a preclinical laboratory that may be a potential dental school health hazard. Visual inspection (conducted in April 2008 by a preclinical crown and bridge course coordinator) of typodonts used by second-year students at the University of Mississippi School of Dentistry found that fourteen out of thirty-nine had black spots on the undersurface of the cheek...

Abstract Biofoam is a replacement packaging for Styrofoam made from natural fibres that are naturally biodegradable and food-safe. Many studies use chemicals starch as matrix adhesive in the manufacture of biofoam. In previous studies, biofoam cups have been developed using mold Rhizopus oligosporus which found coconut fibre. The objective this study was to analyse physical, thermal functional ...

The study investigated the potential of sawdust and disposed water plastics for production wood plastic composite. was obtained from plank market in Yola, while, sachets were hand-picked within Modibbo Adama University premises. gathered sieved into 1.0 2.0 mm particle sizes, thoroughly mixed with already melted sachet at a ratio 1:25 (100: 2500 ml) 1:30 (100:3000 respectively,. mixtures heated...

Today's ubiquitous use of plastics in product design and manufacturing presents significant environmental and human health challenges. Injection molding, one of the most commonly used processes for making plastic products, consumes a significant amount of energy. A methodology for accurately estimating the energy consumed to injection-mold a part would enable environmentally conscious decision ...

background: the effect of mold fungi to allergic sensitization is not well-known. we aimed to evaluate the role of molds in the relation between indoor environment and atopy in asthmatics. materials and methods:the air samples obtained from 66 stable asthmaticsand 35 control subject’shouses were sprayed into sabouraud dextrose agar. allergy skin testing were performed both groups. the tempera...

At harvest, apple fruit are placed into wooden or plastic bins (approximately 400 kg of fruit per bin), which are then transported to storage and packing facilities. Prior to storage, fruit may be drenched with a fungicide to control postharvest diseases (10). Fruit are stored in the bins in either regular atmosphere (RA) or controlled atmosphere (CA) (1 to 2% O2 and 0.5% CO2) at –1 to 3°C (9)....
