This paper examines the distribution of areas burned in forest fires. Empirical size distributions, derived from extensive fire records, for six regions in North America are presented. While they show some commonalities, it appears that a simple power-law distribution of sizes, as has been suggested by some authors, is too simple to describe the distributions over their full range. A stochastic...

Koebner phenomenon, the appearance of preexisting skin lesions following trauma to previously uninvolved skin, has been seen frequently with vitiligo. The type of trauma leading to Koebner phenomenon can vary from scratching, surgical scars, radiotherapy, burns, irritation from drug use and laser therapy. Striae distensae are a form of injury to the skin and in this particular case resulted fro...

The beneficiation of coal through gravity separation plays a key role in industry, allowing for particle size distribution determination and separation of coal in to various sizes for future combustion in boilers, and separation of impurities. For a complete combustion an industrial suspension boiler using bituminous coal requires an average particle size of 45μm and 80 to 85% of particles to b...

Burn injuries remain a global problem even though they are largely preventable. Adequate knowledge is essential to good burn safety practices. This aids prevention and minimizes severity when burn injuries occur. The purpose of this study was to determine the level of burn safety knowledge among literate adult Nigerians in Ile-Ife and Ilesa, South-western Nigeria. We elicited a paucity of burn ...

Accurate estimation of responses of understory plants to disturbance is essential for understanding the efficacy of management activities. However, the ability to assess changes in the abundance of plants may be hampered by inappropriate sampling methodologies. Conventional methods for sampling understory plants may be precise for common species but may fail to adequately characterize abundance...

BACKGROUND Burns are still considered one of the most devastating conditions in emergency medicine affecting both genders and all age groups in developed and developing countries, resulting into physical and psychological scars and cause chronic disabilities. This study was performed to determine the healing effect of curcumin on burn wounds in rat. METHODS Seventy female Sprague-Dawley 180-2...

A serious problem in emergency medicine is the correct evaluation of skin burn depth to make the appropriate choice of treatment. In clinical practice, there is no difficulty in classifying first- and third-degree burns correctly. However, differentiation between the IIa (superficial dermal) and IIb (deep dermal) wounds is problematic even for experienced practitioners. In this work, the use of...

Fire affects and is affected by plants. Vegetation varies in flammability, that is, its general ability to burn, at different levels of ecological organization. To scale from individual plant traits to community flammability states, understanding trait effects on species flammability variation and their interaction is important. Plant traits are the cumulative result of evolution and they show,...

background and purpose: vitamin c is administered orally or intravenously for the treatment of burn wounds. however, effects of the topical application of vitamin c remain unclear. this study aimed to evaluate the effects of topical vitamin c solution on the necrotic tissue volume of second-degree burn wounds. methods: this clinical trial was conducted on 30 patients with second-degree burns ad...
