In a previous study a method for calibrating the loud deli­ vered by flask /tress springs was described. This method did not allow for changes in the mechanical properties of the springs when exposed to boiling water and spring compres­ sion. The effect of 20-25 cycles o f heal exposure and spring compression associated with flask press usage for the curing of denture base resin on the mechanic...

Conventional T-flasks with different sizes and layers are commonly used devices for static cell culture at laboratory scale. Due to their non-deformable structure and requirement of strict manufacture art, the rigid T-flask costs highly in production and transportation and, of course, produces more waste. In this study, we described a pentahedron shaped flexible flask made of a medical applicat...

INTRODUCTION Primary cells in vitro culture scale-up is a crucial issue in cell-based tissue and organ regeneration therapy. Reducing costs and space occupied by the cells cultured in vitro has been an important target. Cells cultured in vitro with the use of bioreactor with dextran microcarriers (Cytodex®) have potentially a chance to meet many of the cell therapy requirements. MATERIAL AND ...

introduction: the purpose of this study was to investigate the effect of flask investment materials on the color changes of different brands of resin denture teeth. methods: resin denture teeth (560) were divided into 2 groups according to the materials used for flask investment (silicone or gypsum). all the specimens were thermocycled between 4°c and 60°c with 60-s dwell times for 1,000 cycles...

Solid wastes from agro-industries may be used as culture medium for enzymes synthesis by filamentous fungi. The brewer’s spent grain (BSG) is generated in abundance in the south of Brazil. Currently, most of this waste is used for animal feed. This work aims to extract and quantify the lipid presents in this residue. The lipids extraction was carried out by Soxhlet extraction method. Initially,...

In a retail company stock control is very important feature. Stock that done manually has many weaknesses especially for large companies transactions in day. This research aims to implement flask framework on the Monitoring application at PT. XYZ. Flask was chosen because of its easy use and lot libraries. The implementation this uses MVC architecture (Model, View, Controller). Then, it will be...

An air-membrane surface (AMS) bioreactor was designed to allow bacteria to grow attached to a surface as a biofilm in contact with air. When Bacillus licheniformis strain EI-34-6, isolated from the surface of a marine alga, was grown in this reactor, cells produced antimicrobial compounds which they did not produce when they were grown in shake flask cultures. An unidentified red pigment was al...

ventilation tube (vt) insertion is the most common otologic operations performed in children, which has great importance in recovery and prevention of hearing loss in children with eustachian tube dysfunction in critical ages of growth development. the location of the vt insertion varies in different studies; the differences are in recovery rates and sequelae of vt insertion. this study is perf...

Compared to other methods of vaccine production, (e.g. culture flask and bioreactor system), the roller culture method for producing rabies vaccine is simpler, and the equipment easier to install and maintain, and also in the event of contamination of one roller, the entire batch need not be discarded. This system provides a much larger surface area than the culture flask, and also ensures a mu...
