The Normalized Difference Vegetation Index (NDVI) was used to characterize the seasonal variation of land cover over the Northeastern Brazil (NEB) with the NOAA/NASA Pathfinder AVHRR Land (PAL) data set. Twenty years of monthly spatial-aggregated NDVI climatology was determined by calculating lower, mean, and upper NDVI values using a 0.5 lat by 0.5 log grid cell size. The results indicated tha...

Using enrichment procedures, 45 organic solvent-tolerant lipase producer bacterial strains were screened from areas contaminated by oil and organic solvents. Among the strains, 15 isolates exhibited extreme stability toward organic solvents and high lipolytic activity. The NEB-1 isolate which was later identified as Pseudomonas sp. strain NEB-1 by biochemical tests and 16S rDNA gene sequence an...

O turismo se consolidou no mundo como uma atividade de grande relevância, sobretudo aspecto econômico. Pela sua característica multifacetada, incluída a vertente espacial, pode ser estudado forma compartimentada ou integrando seus diversos componentes. No espaço geográfico localizam os elementos fixos e fluxos turísticos, que dinamizam conforme constituição desse espaço. Na região Nordeste do B...

This paper considers potential cellulosic ethanol production from Southern slash pine (Pinus elliottii) plantations. The net energy balance (NEB), emissions and associated environmental impacts, unit cost of ethanol production, and associated changes to forest land values are calculated and preliminary results are given. The NEB is found to be positive at 2.2, meaning that for every unit of ene...

Because inorganic solid electrolytes are one of the key components for application to all-solid-state batteries, high-ionic-conductivity materials must be developed. Therefore we propose a method efficiently evaluating activation energy ionic diffusion by calculating potential-energy surface (PES), searching optimal path an algorithm developed using dynamic programming (DP), and corresponding n...

BACKGROUND Amaranthus tuberculatus is a problematic weed species in Midwest USA agricultural systems. Inhibitors of 4-hydroxyphenylpyruvate dioxygenase (HPPD) are an important chemistry for management numerous cropping Here, we characterize the genetic architecture underlying HPPD-inhibitor resistance trait A. population (NEB). RESULTS Dose–response studies F1 generation identified as dominant ...

Abstract The search for better and cheaper electrocatalysts is vital in the global transition to renewable energy resources. High‐entropy alloys (HEAs) provide a near‐infinite number of different with approximately continuous properties such as catalytic activity. In this work, activity electrochemical oxygen reduction reaction function molar composition Ag‐Ir‐Pd‐Pt‐Ru HEA treated landscape whe...
