A study was conducted in two selected areas of the Brazilian cerrado using Landsat imagery during a five years period (1996-2000), to address the following estimation issues: (1) burnt area using statistical sample techniques; (2) burnt scars permanence; and (3) recurrence of biomass burning. Regarding the burnt area estimates, a decrease of approximately 60% was observed during the period and ...

Asphaltic concrete for pavement construction in India are produced by using crushed stone, gravels etc. as aggregate. In north-Eastern region of India, there is a scarcity of stone aggregate. Therefore the road engineers are always in search of an optional material as aggregate which can replace the regularly used material. The purpose of this work was to evaluate the utilization of substandard...

Serum elastase and its inhibitors were determined in the sera of heavily burnt patients. Serum elastase levels were elevated at two to eight days after a severe burn-accident and returned towards normal values from the 10th day on. Both alpha1-antitrypsin and alpha2-macroglobulin levels were also elevated in the sera of heavily burnt patients. alpha1-Antitrypsin showed a parallel evolution to t...

Analysis of the spatiotemporal pattern burned areas over time is necessary to understand how fire behavior in Himalayan region has altered as a result complex climatic variables. The differenced Normalized Burnt Ratio (NBR) calculated utilizing cloud-based platform Google Earth Engine (GEE) quantify extent regions. spatial distribution burnt last 21 years been examined and correlated with edaph...

Reptiles in urban remnants are threatened with extinction by increased fire frequency, habitat fragmentation caused by urban development, and competition and predation from exotic species. Understanding how urban reptiles respond to and recover from such disturbances is key to their conservation. We monitored the recovery of an urban reptile community for five years following a summer wildfire ...

The purpose of this research is to explore the variability on the soil thermal conductivity -after a prescribe fire, and to assess the effects of the ashes on the heat transfer once it’s were incorporated into the soil matrix. Sampling plot was located in the Montgrí Massif (NE of Spain). A set of 42 soil samples between surface and 5 cm depth was collected before and after the fire. To charac...

Fortuitous sequences of flips of the top of a stack of n burnt pancakes for all n > 24. Summary Burnt pancakes problem was defined by Gates and Papadimitriou in 1979. They proved that g(−f n) ≥ 3n/2 − 1. In 1995 Cohen and Blum conjectured that g(n) = g(−I n) and proved that g(−I n) = g(−f n) + 1 ≥ 3n/2.
