Anomalies of the coronary arteries are uncommon and often asymptomatic. Double right coronary artery (RCA) is a very rare coronary anomaly. So far, the number of reported cases of double RCA is low. We describe a case of a 50-year-old female patient hospitalised with the diagnosis of unstable angina pectoris. RCA injection showed filling of two separately originating RCA, coursing towards the r...

A randomised, double-blinded, controlled trial was performed to compare traditional digital blocks with single subcutaneous palmar injection blocks at the base of the finger. A search for randomised controlled trials of digital blocks through MEDLINE, EMBASE, Cochrane Controlled Trials Register and CBM was conducted and a meta-analysis including the current trial was performed. The current tria...

Dedicated in-cylinder reforming where gasoline fuel is injected directly into a rich mixture can control the combustion of engines. This work investigates effects injection parameters and on direction (GDI) engine operated under low-temperature mode. The single-cylinder research modified from dedicated 4-cylinder spark-ignited used in subcompact passenger vehicles. Experimental kinetics results...

Nowadays, the major challenge of diesel engines development is simultaneous nitrogen oxides and soot emissions reduction without the thermal efficiency drop. Hence, different combustion concepts should be investigated to reach optimum emission and performance conditions in diesel engines without expensive aftertreatment systems. This paper presents the results of a study on a dual fuel (DF) eng...

Abstract This study aimed to assess the effect of inferior alveolar nerve (IAN) block mandible and infiltration anesthesia maxilla using lidocaine plus epinephrine or prilocaine with felypressin anesthetic agents on systolic diastolic blood pressures, heart rate (HR) peripheral oxygen saturation patients. randomized double-blind clinical trial evaluated 112 patients in four groups (n=28) based ...
