Setting properties of bone substitutes are improved using an injectable system. The injectable bone graft substitutes can be molded to the shape of the bone cavity and set in situ when injected. Such system is useful for surgical operation. The powder part of the injectable bone cement is included of β-tricalcium phosphate, calcium carbonate, and dicalcium phosphate and the liquid part contains...
We have developed a soft lithography method to replicate polymeric integrated optical devices. In this method, the master device and the molded replica are made of the same materials, allowing direct comparison. To evaluate the quality of the replication, microring optical resonators are chosen as test devices because of their sensitivity to small fabrication errors. The master devices are prec...
This study experimentally investigates the effect of processing parameters on mechanical properties of injection molded copolymer. This paper presents an experimental study on the effects of processing parameters including melt temperature, injection pressure and amount preliminary materials on tensile strength of injection molded copolymer PP-WGRT. Polypropylene (PP - supplied by T.P.C of Iran...
Prescribing by nurses and midwives continues to expand has consistently been evaluated as safe effective. This article is part one of two exploring the core professional, legal ethical dimensions prescribing. Reference made a contemporary prescribing model, RAPID-CASE, devised authors demonstrate application key practice principles. The importance structured approach demonstrated with reference...
A new thermoplastic material with extremely desirable physical and radiation shielding properties is presented. The material softens between 108 degrees F and 132 degrees F and can then be easily molded to any desired shape. As it cools down it hardens at about 102 degrees F, retaining its molded shape. It is very light (rho = 1.66 g/cc), compared to most other compensating and shielding materi...
Plastics is one of the world’s largest and fastest growing industries, ranked as one of the few multi-billion dollar industries. Due to the vast improvements in polymers and production processes, plastics are now amongst the world’s most widely used materials, with the world consumption of polymers surpassing steel in volume and weight. Injection molding represents approximately 32% (by weight)...
calligraphy in plaster molding has long been a unique platform for professional designers and decorative calligraphers due to the ease of molding the plaster and the longevity of the work. since the origin of the kufi alphabet used in plaster inscriptions is simplekufi, it is generallybelieved that the common letters must be drawn alike. however, as exemplified in the phrase under study, the mo...
In this paper, we demonstrate recordings of the ion channel activity across the cell membrane in a biological cell by employing the so-called patch clamping technique on an injection-molded polymer microfluidic device. The findings will allow direct recordings of ion channel activity to be made using the cheapest materials and production platform to date and with the potential for very high thr...
this research is about the political economy of china in central asia. in this research the political & economic interactions affected on chinas political economy in central asia are examined. chinas goal of presence in central asia including political-security, economic and energy goals is described in one part. in another part, the trade relations between china and central asian countries ar...
Fuel cells constitute one of the most promising sources of clean energy for the 21 century and bipolar plate is an important component of a PEM fuel cell. Polymers filled with conducting fibers have been chosen as a candidate material for bipolar plates which needs to fulfill the surface conductivity requirement. In the present paper, effect of processing parameters including melt temperature, ...
