Abstract: Extraction of relevant information from remotely sensed imagery is essential for the identification of changes in the earth’s environment. Methods for converting the data collected at the sensor to surface reflectance have been under constant improvement since the beginning of the Landsat program. The time and effort needed to perform this task has recently been eliminated with the publication of the USGS Landsat CDR. This paper compares the data available from the USGS with a simple dark object subtraction method for determining surface reflectance. Our goal is to determine if the USGS data set is comparable to previous methods. We find that the USGS data set is strongly correlated with the simpler DOS method. While clear differences in absolute surface reflectance are observed in the visible and near-IR bands, the trends in the data over time are consistent. This suggests that previous trend studies using the simpler methods do not need to be revisited using the newer data. The findi

Abstract: The olive oil represents about 3% from the worldwide production of vegetable oils, but due to high organic content (lipids 0.2-1%, carboxylic acids 0.5-1.5%, sugars 1-8%, polyphenols and pectins 1-1.5%, tannins, polyalcohols, etc.), the wastewaters resulted from olive oil mills are important pollutants, about 30 million tons of wastewaters are produced per year in the world. The biological processes are the most environmentally compatible and least expensive methods for wastewater treatment. The immobilization of whole cells for the degradation of diferent compounds in wastewater can provide several advantages: high activity, yield, operational stability and possible reuse. Considering this, the aim of this paper is the comparative investigation of the lipids biodegradation from olive mill wastewaters using two different bioreactors containing immobilized mixture of Bacillus spp. (Bacillus subtilis, Bacillus megaterium, Bacillus licheniformis and Bacillus ortoliquefaciens in equal rati
