rainfall erosivity is the ability of rainfall to detach the soil particles. this study was conducted to evaluate spatial variability of rainfall erosivity indices in khouzestan province. the point data of indices (ei30, aim, ke>1 and onchev indices) in 74 stations were used to generate spatial erosivity maps through deterministic and geostatistical interpolation methods (radial basis functions,...

Introduction: Ne-E(L) is one of the anomalous noble gas components that ultimately led to the discovery of presolar grains in meteorites. The component is extremely enriched in 22 Ne and this fact prompted the idea that the 22 Ne is from the decay of 22 Na [1]. The carrier of Ne-E(L) is presolar graphite [2], which has been extracted from Murchison [3] and Orgueil [4]. There are four graphite-r...

A model was developed for the fate of the natural estrogens estrone (E1) and estradiol (E2) in municipal sewage collection systems. Six municipalities throughout the Northern Hemisphere provided data to aide in the calculation of the biotransformation/degradation kinetics of the natural estrogens estrone (E1) and estradiol (E2) in wastewater collection systems. The mean pseudo-first-order kinet...

This data article refers to the report Δ(9)-Tetrahydrocannabinolic acid synthase (THCAS) production in Pichia pastoris enables chemical synthesis of cannabinoids (Lange et. al. 2015) [2]. THCAS was produced on a 2 L lab scale using recombinant P. pastoris KM71 KE1. Enrichment of THCAS as a technically pure enzyme was realized using dialysis and cationic exchange chromatography. nLC-ESI-MS/MS an...

The behavior of natural estrogens was examined by separately spiking 17β-estradiol (E2) and estrone (E1) into semicontinuous activated sludge reactors operated under aerobic, anaerobic and sequential anaerobic/aerobic conditions. Under aerobic and anaerobic conditions, E1 was formed from E2. The conversion of E1 to E2 was maximum conversion of E2 to E1 was higher than t E1 to E2. Overall, the d...

BACKGROUND One of the crucial factors for a sustainable and economical production of lignocellulosic based bioethanol is the availability of a robust fermenting microorganism with high tolerance to inhibitors generated during the pretreatment of lignocellulosic raw materials, since these inhibitors are known to severely hinder growth and fermentation. RESULTS A long-term adaptation in repetit...
