A 27-yr-old postgraduate student was found lying at the floor of an unsealed underground dry area, where a valve-opened empty cylinder of liquid nitrogen (150 L) was connected to a cap-removed empty Dewar-flask (10 L) via a copper infusion tube. No injury was found externally or internally. There were petechiae in the bilateral conjunctivae and periorbital skin. The dry area, measuring 300 x 13...

Abstract In this study, the drying kinetics, effective moisture diffusivity ( D eff ), specific energy consumption (SEC), colour, and shrinkage S b ) of pomegranate arils were compared when dried by convective (CV) microwave (MW) drying. The experiments performed at air temperature 50, 60, 70°C velocity 1 m/s for CV 270, 450, 630 W MW results showed that increasing power increased . calculation...

UNLABELLED Early monitoring of non-alcoholic fatty liver disease (NAFLD) progression in obese patients is important to avoid the development of complications associated with fatty infiltration. THE AIM of this study was to investigate the relationship between the degrees of fatty infiltration and reduced vascular compliance in NAFLD patients in the three main hepatic vessels. MATERIAL AND M...

Intracellular calcium ([Ca]i) release from SER stores plays an important role in cell signaling. These stores are rapidly refilled via influx through voltage gated calcium channels or spontaneously via store-operated calcium channels (SOCC), and subsequent pumping by smooth endoplasmic reticulum Ca -ATPases (SERCA). We measured [Ca]i transients in isolated Fura-2 loaded superior cervical gangli...

purpose: to evaluate the effect of laser in situ keratomileusis (lasik) on stereoacuity (sa). methods: in this prospective study, 200 patients scheduled for lasik were evaluated for sa preoperatively and one week and one and three months postoperatively by random dot test. patients with preoperative sa worse than 480 sec/arc were excluded. results: patients included 138 female (69%) and 62 male...

Metabolic pathways involved in the activation of polymorphonuclear leukocytes (PMNs) were characterized by using chemoattractants with equivalent chemotactic activity but widely disparate ability to stimulate superoxide production [N-formylmethionylleucylphenylalanine (fMet-Leu-Phe) much greater than leukotriene B4]. Leukotriene B4 stimulated a low level of superoxide production that plateaued ...

The purpose of this research is to achieve the optimal parameters for producing forged aluminium alloy 7075 aircraft door bracket by using finite element modelling (FEM) with commercial DEFORM-3D V6.1 and physical simulations with plasticine and Plexiglas dies. Also, forging speed has been examined as the main factor for controlling to produce a part without any defects. The results of Physical...

introduction: foot-and-mouth disease (fmd) is a highly contagious and economically devastating viral disease of livestock that is categorized in list a of animal diseases by the world organisation for animal health (oie). vaccination is effective against fmd and the vaccine production centers largely use the industrial ultra-filtration and chromatography in order to remove the cellular proteins...

The purpose of this study was to assess the reliability of a method for testing peak torque and work output of the knee extensor muscle during concentric and eccentric loading at three velocities of exercise (60 degrees, 120 degrees, and 180 degrees/sec). Fourteen healthy men (23-32 years of age) performed exercises of the quadriceps femoris muscles during concentric and eccentric loading, with...
