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.

With the increasing temporal resolution of medium spatial resolution data, seasonal features are becoming more readily available for land cover characterization. However, in the tropical regions, images can be severely contaminated by clouds during the rainy season and fires during the dry season, with possible effects to seasonal features. In this study, we evaluated the performance of seasona...

BACKGROUND One of the effects of burn injury is production of reactive oxygen species increasing general-structural damage. Such a condition is called oxidative stress. The purpose of this research was to find out whether oxidative stress is present in burnt children treated routinely and, if so, in which phase of the disease it is the most severe and how long it persists. MATERIAL AND METHOD...

The Cerrado is the second largest biome in Brazil after the Amazon and is the savanna with the highest biodiversity in the world. Serra Tombador Natural Reserve (STNR) is the largest private reserve located in Goiás State, and the fourth largest in the Cerrado biome. The present study aimed to map the burnt areas and to describe the spatial patterns of fire recurrence and its interactions with ...

UNLABELLED In Mediterranean regions, fires threaten terrestrial tortoises. Nevertheless, varying proportions of adults survive fire; these surviving individuals can play a central role for population recovery. The regions devastated by fire often include important habitat of Hermann's tortoises (Testudo hermanni hermanni), so assessing the ability of survivors to persist is essential for conser...

More than 72,000 hectares of western Tasmania were burnt in 2016 due to bushfires. Bushfires in Tasmania has high social, economical, and environmental impacts. The remote delineation of these bushfires has paramount importance for decision-making authorities to help people in emergencies and planning. Considering the fact that delineation uncertainty from Earth Observation [EO] data is inevita...

In the present study, the effects of the acute and chronic oral administrations (po) of curcumin in the absence and presence of morphine and naloxone was investigated on the sensation of acute corneal pain in rats. Acute corneal pain was induced by the local application of hypertonic saline (5 M NaCl) on the corneal surface, and the number of eye wipes was then counted for 30 s. Subcutaneous (s...
