In order to analyze the effect of hydrogen rich gas addition (HRG) on lean burn engine’s thermal efficiency and emission, an experimental research was conducted on a gasoline direct injection (GDI) engine using definite fraction of HRG. The results showed that HRG addition could significantly extend the lean operation limit, improve the engine’s lean burn ability, and decrease burn duration. HR...

This is a study of 120 patients of either sex and all ages who had sustained deep burns of up to 40% of the total body surface area. Half the patients underwent early excision and skin autografting (i.e., within 4-7 days of sustaining burn injury) while the rest underwent delayed excision and skin autografting (i.e., within 1-4 weeks post-burn). Significant differences were found in favour of t...

Correspondence to: Folke Sjöberg, Burn Center, Linköping University Hospital, Linköping, Sweden. E-mail: [email protected] Outcome after burn injury, as also paralleled by other trauma, has been improving steadily over the years. In this aspect a significant improvement was seen especially in the 1970-ties when the 50% survival chance from a burn injury increased from 45% total body surface ...

Development of malignant tumours in chronic burn wounds or scars is extremely rare, but a frequently reported complication. Most of these tumours are squamous cell carcinoma and, more occasionally, basal cell carcinoma and malignant melanoma are reported. The interval between the initial burn and the diagnosis of the tumour is usually long; 20-30 years or more. A large number of case reports an...

BACKGROUND Clinical evidence indicates that late acute renal failure (ARF) predicts high mortality in severely burned patients but the pathophysiology of late ARF remains undefined. This study was designed to test the hypothesis that sustained reactive oxygen species (ROS) induced late ARF in a severely burned rat model and to investigate the signaling mechanisms involved. MATERIALS AND METHO...

Global optimization of transport aircraft is performed to minimize fuel burn for a specified mission. The design space includes the geometry, wing airfoils, primary structure, engine size and cycle parameters, and the flight profile parameters. The method employs a number of physics-based models for structural sizing and weight estimation, viscous CFD for all major aerodynamic components, and a...

Hand burns predominantly affect young adults, and therefore have serious social and financial implications. In the present work, 106 patients with less than 25% body surface area burns and acute partial-thickness burned hands were managed using polyethylene bags and 1% local silver sulphadiazine (SSD) cream or moist exposed burn ointment (MEBO). Females made up 61.3% of the cases and flame burn...

this study was conducted to determine the causes and outcomes of burn in patients referred to shahid mohammadi hospital in bandar abbass, southern iran, in which 212 burned patients were assessed from march 2007 to march 2008 .mean age of patients was 22.14 yr. heat contact was the main cause of burn with 92.5%. 49.1% of total burns occurred among less than 20 yr old people. mortality rate was ...

OBJECTIVE Normal iron handling appears to be disrupted in critically ill patients leading to hypoferremia that may contribute to systemic inflammation. Ceruloplasmin (Cp), an acute phase reactant protein that can convert ferrous iron to its less reactive ferric form facilitating binding to ferritin, has ferroxidase activity that is important to iron handling. Genetic absence of Cp decreases iro...

A new reduced size ITER-RC superconducting tokamak concept is proposed with the goals of studying burn physics either in an inductively driven standard tokamak (ST) mode of operation, or in a quasi-steady state advanced tokamak (AT) mode sustained by non-inductive means. This is achieved by reducing the radiation shield thickness protecting the superconducting magnet by 0.5 m relative to ITER a...
