AIM To study the antioxidant activity, UV absorption, concentration and stability of ascorbic acid (AA) in porcine and bovine aqueous humour (AH). METHODS Porcine and bovine AH was taken within 5 min after death and frozen at -70 degrees C. The characteristic UV absorption band of AA and the concentration of AA in AH was determined by UV spectrophotometry. The antioxidant activity of AA to se...

The fabrication of self-assembled Au droplets is successfully demonstrated on various GaAs (n11)B, where n is 2, 4, 5, 7, 8, and 9, by the systematic variation of the Au deposition amount (DA) from 2 to 12 nm with subsequent annealing at 550°C. Under an identical growth condition, the self-assembled Au droplets of mini to supersizes are successfully synthesized via the Volmer-Weber growth mode....

the second half of the third hijri century, coinciding with the reign of three caliphs, al-mu’tamid (256-79 ah), al-mu’tadhid (279-89 ah), and al-muktafi (289-95 ah), abbasids restored their authority and renewed their organization. this reform process which was began by abu ahmad al-muwaffaq (d. 278 ah) and reached its climax at the time of abu al-abbas al-mu’tadhid stood between two decline p...

The influence of discharge rate, ambient temperature, and phase change material on the maximum temperature highest difference was investigated. battery tested with without under extreme rates (4C 5C) temperatures (310 K 320 K). Results showed that a reduced from 327.94 to 306.45 for 14.6 Ah lithium-ion discharged at 5C-rate K. Quantitatively determined parameter effects revealed PCM considerabl...

A 21-year old man with history of 8 year palpitation was referred for electrophysiologic study and possible radiofrequency ablation. Physical examination and transthoracic echocardiographic study did not disclose any abnormality. Baseline ECG showed normal sinus rhythm with normal PR and QRS intervals and no evidence of preexcitation. Antiarrhythmic drugs (propranolol and verapamil) were discon...

BACKGROUND The antiarrhythmic effects of sodium channel and calcium channel blockers are known to be rate dependent. Little is known about the rate-dependent effect of adenosine on human atrioventricular (AV) nodal conduction. The purpose of this study was to determine whether the negative dromotropic effect of adenosine is dependent on heart rate. METHODS AND RESULTS Atrial pacing at 20-mill...

A 25-year-old woman with a 5-year history of paroxysmal supraventricular tachycardia underwent an electrophysiologic procedure. The baseline sinus cycle length, atrial–His-bundle (AH) interval, and His-bundle–ventricular (HV) interval were 750, 60, and 50 msec, respectively. Paroxysmal supraventricular tachycardia with a cycle length of 320 msec was induced by programmed atrial stimulation with...

In Mobile Wireless Sensor Networks (MWSNs), nodes are supplemented with implicit or explicit mechanisms that enable these devices to move in space. The packet loss is one of the main challenges that occur due to mobility of such networks and it comes in parallel with energy consumption. Moreover, data collection with the minimum energy consumption is one of the important issues in wireless sens...
