Практика показала, что применение самопередвижных машин сыграло положительную роль при очистке небольших партий зерна и в хозяйствах. Такая технология не лишена недостатков. В частности, она требует проведения большого количества перевалочных работ, отличается повышенными затратами на единицу обработанной продукции, всегда соблюдаются требования экологии. Первоочередной задачей устранении этих ...

one of the disadvantages of conventional milling tools is to produce a large amount of heat in cutting zone and so making the tool warmer. as a result, the tool would be worn and its life time would be reduced. therefore, in long time machining, it is essential to change inserts and tools, continiously. a milling tool with self rotary cutting inserts was designed and manufactured that enables i...

Xylose-to-xylitol bioconversion by Ca-alginate entrapped Candida guilliermondii cells in sugarcane bagasse hemicellulosic hydrolysate was carried out in erlenmeyer flasks using the repeated-batch mode of fermentation. The hydrolysate was supplemented or not with ammonium sulfate and/or rice bran extract at the beginning of each repeated batch. Altogether, six sets of three repeated-batches were...

AIM The main objective of this study was to compare the in vitro delivery of salbutamol from a chlorofluorocarbon(CFC)-propelled pressurised metered-dose inhaler (pMDI) versus a newly developed hydrofluoroalkane(HFA)-propelled pMDI through various spacers. In addition, we aimed to study the effect on bronchodilator response when using an optimal pMDI/spacer combination for aerosol delivery comp...
