this thesis is presented 10 ghz voltage controlled ring oscillator for high speed application. the voltage controlled ring oscillator was designed and fabricated in 0.13یm cmos technology. the oscillator is 7-stages ring oscillator with one inverter replaced by nand-gate for shutting down in the ring oscillator during idle mode. tri-state inverter was used to control of 126 bit vector in ri...
Intracellular Mg2+ and natural polyamines block outward currents in BK channels in a highly voltage-dependent manner. Here we investigate the contribution of the ring of eight negatively charged residues (4 x E321/E324) at the entrance to the inner vestibule of BK channels to this block. Channels with or without (E321N/E324N) the ring of negative charge were expressed in oocytes and unitary cur...
for the first time nakayama introduced qf-ring. in 1967 carl. faith and elbert a. walker showed that r is qf-ring if and only if each injective right r-module is projective if and only if each injective left r-modules is projective. in 1987 s.k.jain and s.r.lopez-permouth proved that every ring homomorphic images of r has the property that each cyclic s-module is essentialy embeddable in dire...
The aim of this study was to investigate the anesthetic effect and risk of epinephrine for subcutaneous single injection digital block. Either 3.0 mL 1.0% Lidocaine or a 3.0 mL 1.0% Lidocaine with (1 : 100,000) epinephrine was injected into the subcutaneous space at the middle point of the palmar digital crease of the 18 middle fingers of 9 healthy volunteers. The SpO(2) of the fingers decrease...
A 26-yr-old woman, with an intrauterine pregnancy at 29 6⁄7 weeks’ gestation, presented to the emergency room of The Milton S. Hershey Medical Center reporting severe pain in the right flank. Abdominal ultrasound did not show a renal or ureteral calculus, but delayed contrast filling of the right urinary collecting system seen on an abdominal computed tomography scan was consistent with right u...
AIM To perform ultrasound biomicroscopic analysis of pseudophakic pupillary block glaucoma induced by lens capsule and a Soemmering's ring and its resolution, and to elucidate the pathophysiology of this glaucoma. METHODS A woman with pseudophakic pupillary block glaucoma underwent successful neodymium:YAG (Nd:YAG) laser photodisruption of the lens capsule through a laser iridotomised colobom...
BACKGROUND Digital nerve blocks are commonly used as effective techniques of anaesthesia to allow a variety of surgical procedures performed on digits. This study was conducted to compare the efficacy of volar subcutaneous single injection block and the traditional dorsal two injections digital block. METHODS This randomized controlled trial was conducted at Plastic and Reconstructive Surgery...
Masson’s tumor or intravascular papillary endothelial hyperplasia is a benign lesion of the skin and subcutaneous tissue. It due to reactive proliferation cells with formations related thrombus. poses an interesting diagnostic differential as clinical signs symptoms are nonspecific. The diagnosis based on histopathology. We report case hemangioma occurring right ring finger.
BACKGROUND Two commonly used methods of digital nerve block with local anesthetic are the two-injection dorsal technique and the single-injection volar subcutaneous technique. The authors compared these two digital block techniques with respect to local anesthetic injection pain and recipient preference of anesthetic technique. METHODS Twenty-seven volunteers had the long finger of each hand ...
