Abstract:
Burn constitutes a major public health problem, especially in low or middle-income countries where over 95% of all burn deaths occur. According to the World Health Organisation, an estimated 1,95,000 deaths every year are caused by burns, the vast majority occur in low and middle-income countries. The present medico-legal study aimed to assess the cause of death and rate of survival related to different types of burn injuries.

Abstract:
Little is known about the fire ecology of desert springs, despite their importance for biodiversity and for provision of ecosystem services. Desert spring ecosystems are characterised by high and continuous fuel loads compared with surrounding uplands, suggesting that fire may play a significant ecological role. For the Ash Meadows spring complex in the south-western USA, we used ecological-niche factor analysis and a Bayesian model averaging regression technique to characterise the environmental conditions associated with spatially explicit burn probability and burn severity over a 24-year pe

Abstract:
Abstract Introduction Mortality following burn injury is influenced by many objective factors. Over the past several decades, numerous predictive formulas have been developed to estimate the probability of death from burn injury. Despite the preponderance of models, there are relatively few widely accepted objective measures found to impact mortality in burn patients. These factors include sex, age, burn depth, TBSA, and presence of inhalation injury. In this study, we retrospectively analyzed mortality in the burn patients at our level one trauma center to identify prognostic factors. Methods

Abstract:
Risk assessment of forest fires requires an integrated estimation of fire occurrence probability and burn probability because fire spread is largely influenced by ignition locations as well as fuels, weather, topography and other environmental factors. This study aims to assess forest fire risk over a large forested landscape using both fire occurrence and burn probabilities. First, we use a spatial point processing method to generate a fire occurrence probability surface. We then perform a Monte Carlo fire spread simulation using multiple fire ignition points generated from the fire occurrenc

Abstract Diluted combustion with exhaust gas recirculation (EGR) has been widely employed to improve the fuel economy of spark ignition engines. The combustion kinetics, however, are affected and the flame propagation speed is decreased. In order to compensate for this adverse effect, the spark timing needs to be recalibrated to achieve maximum brake torque (MBT). At high levels of EGR dilution, the spark timing is constrained by two ignition limits: 1) the partial-burn limit where the spark timing is retarded from MBT and 2) the misfire limit where the spark timing is too advanced.
