In this study, a novel numerical method is proposed for determination of mode-I interlaminar fracture toughness, GIc, in multi-directional (MD) double cantilever beam (DCB) specimens using fracture properties of unidirectional DCB specimens. Two factors, β and Dc are defined to minimize the undesirable effects on strain energy release rate. β describes the difference between maximum and average...

Homogenous charge compression ignition (HCCI) combustion is spontaneous multi-site combustion of a nominally premixed air/fuel mixture that exhibits high rate of pressure rise and short combustion duration. To avoid excessive pressure rise rate and knocking, HCCI engines are fueled with highly diluted mixture using a combination of excess air and/or EGR. HCCI combustion is attractive due to ...

Background: Alopecia Areata (AA) is a recurrent non-scarring type of hair loss that can affect any hair-bearing area. Prognosis of AA is unpredictable and most patients experience more than one episode of hair loss.

Background: Intravenous regional anesthesia is a simple and reliable method for upper extremity surgery. In order to increase the quality of blocks and reduce the amount of pain, many drugs are used with lidocaine. In this study, the effect of ketorolac-lidocaine in intravenous regional anesthesia was investigated. Methods: 40 patients undergoing elective upper limb with America Society of Ane...

Objective: Evaluation of onset and duration of peripheral nerve blockage with alkalinized lidocaine by borate buffer instead of sodium bicarbonate. Study design: Experimental randomized cross-over study. Animals: Forty male Sprague-Dawley rats (body weight 200–300 g) were used in this study. Methods: Four 1.0% lidocaine solutions were prepared from commercially available solutions. The treat...
