Carbon dioxide flooding is considered to be one of the most effective enhanced oil recovery methods for the light oil reservoirs. Depending on the operating pressure, the process might be miscible or immiscible. Minimum miscibility pressure (MMP) is the most important parameter for assessing the applicability of any miscible gas flood for an oil reservoir. The miscibility condition is determine...

Halloysite nanotubes-thermoplastic polyurethane (HNTs-TPU) nanocomposites are attractive products due to increasing demands for specialized materials. This study attempts to optimize the parameters for injection just before marketing. The study shows the importance of the preparation of the samples and how well these parameters play their roles in the injection. The control parameters for injec...

Introduction: Epinephrine-containing lidocaine is the most used anestheic drug in dentistry. The aim of this study was to investigate the hemodynamic changes following local infiltration of 2%lidocaine with 1:80,000 epinephrine in subjects undergoing orthognatic surgery under general anesthesia. Methods: Twenty five patients without any systemic disease participated. After general anesthesia, t...

1. We have compared the effect of central and peripheral administration of angiotensin II and (1-succinamoly-5-valine-8-phenylglycine)angiotensin II on blood pressure of male conscious unrestrained rats with normal blood pressure, and with spontaneous hypertension or chronic renal hypertension. 2. After central and peripheral injection of angiotensin II all rats exhibited a significant dose-rel...

Investigations are carried out to evaluate the performance of a low heat rejection (LHR) diesel engine consisting of different versions such as ceramic coated cylinder head engine-LHR-1; Air gap insulated piston and air gap insulated linerLHR-2; and Ceramic coated cylinder head, air gap insulated piston and air gap insulated liner –LHR-3 with normal temperature condition of linseed oil with var...
