In the present work, deoxidation and refining of 316LVM steel (Low carbon Vacuum Melted) during the vacuum induction melting process was studied. This grade of stainless steel is one of the most import...

poly (propylene fumarate) (ppf), a linear unsaturated polyester consisting of alternating propylene glycol and fumaric acid units, can be cured in vivo to fill the skeletal defects with minimal surgical intervention. many different methods have been reported for synthesizing ppf, but none of them gives a clear method. the present paper introduces two new methods in ppf synthesis: modified reflu...

rier for a variety of edible antimicrobial agents. Technologies designed to pasteurize processed meats after final packaging have received copious attention. Post pasteurization of vacuum packaged cooked products consists of hot water or steam immersion followed by immediate chilling. Irradiation (gamma, electron beam or X-ray) of cooked vacuum or MAP packaged products can produce very acceptab...

BACKGROUND Due to the health-promoting value of black radish, authors decided to investigate the feasibility of forming - from its roots - chips, using the process of microwave-vacuum puffing. In order to produce desirable quality of chips, there is a need to determine the most advantageous values of process parameters. The main goal of the paper is to investigate the possibility of determining...

persian sturgeon (acipenser persicus) is one of the most important fish in caspian sea and demand for its fillets is considerable, study to improve the packaging and protect their quality during storage is necessary. in this study persian sturgeon fillets were packed under 30% vacuum then freezed and effect of this packaging method on decreasing and delaying lipid rancidity was studied by measu...

background: acute opioid overdose is a common cause of admission in emergency department. in spite of the fact that naloxone is the main therapy for decades, there are controversies about the proper way of its use. this study aimed to compare two most recommended administration modes for naloxone. methods: in this single-blind clinical trial, 80 patients with methadone overdose syndrome were ra...

The present study examined whether premovement central neural processing in Parkinson's disease was related to functional motor disability and plasma L-dopa concentration. Reaction time (RT) performance in simple and choice RT tasks was assessed while plasma L-dopa levels were controlled by continuous IV L-dopa infusion in five parkinsonian patients. Five age-matched controls performed the same...

Quantum electromagnetic fluctuations induce forces between neutral particles, known as the van der Waals and Casimir interactions. These fundamental forces, mediated by virtual photons from the vacuum, play an important role in basic physics and chemistry and in emerging technologies involving, e.g., microelectromechanical systems or quantum information processing. Here we show that these inter...
