The halotolerant bacterial strain BU-4, isolated from a hypersaline environment, was identified as an exopolysaccharide (EPS) producer. Pretreatment liquids of steam-exploded quinoa stalks and enzymatic hydrolysates of Curupaú sawdust were evaluated as carbon sources for EPS production with the BU-4 strain, and the produced EPS was characterized using FTIR, TGA, and SEM. Cultivation was performed

Purpose The purpose of this study is to better understand online anonymity in the global file-sharing community in the context of social norms and copyright law. The study describes the respondents in terms of use of Virtual Private Networks (VPNs) or similar services with respect to age, gender, geographical location, as well as analysing the correlation with file-sharing frequencies.

Växter behöver ljus. Ljuset omvandlas genom fotosyntesen till kemisk energi som kan lagras i växten. Mer ljus ger således mer energi men bara upp till en viss gräns. När växten inte längre kan hantera mängden ljus som den utsätts för kommer flaskhalsar i processen orsaka att högenergetiska tillstånd blir mer långlivade. Dessa reaktiva ämnen kan då orsaka skada på närliggande komponenter, vilket kaPlants and algae need light to drive the photosynthetic machinery. An excess of light will, however, result in damage to the photosynthetic machinery and to the rest of the organism. The surplus of energy, when exposed to light stress is converted into less harmful heat energy through a process called non-photochemical quenching. This quenching is partly dependent on the xanthophyll pool located i

In order to reduce the net climate impact of concrete production, it is necessary for the industry to undertake several actions. Among these is to include fly ash and slag as supplementary cementitious materials. Accordingly, this project has studied concrete containing low-calcium fly ash or ground-granulated blast-furnace slag. In incorporating fly ash or slag as supplementary material, the ceme

The morphology and the anatomy of the 13 species presently included in the genus Fulgensia were surveyed. Caloplaca aurea and C. paulii, two speciesregarded as closely related to Fulgensia by earlier authors, were also included in the study. Fulgensia was found to exhibit a great variation in both morphology and anatomy. The differences in size, shape and septation of the spores, in the anatomy of

OBJECTIVE: Endothelin (ET) has, since its discovery, increasingly been considered a key player in the pathophysiological processes of cerebral vasospasm in the course of subarachnoid hemorrhage, although it remains unclear how ET is involved. We present data that indicate an inherent capacity of human cerebral arteries to change their sensitivity to ET. METHODS: Human cerebral arteries were obtain

A key premise of the heuristics-and-biases program is that heuristics are “quite useful.” Let us now pay more than lip service to this premise, and analyse the environmental structures that make heuristics more or less useful. Let us also strike from the long list of biases those phenomena that are not biases and explore to what degree those that remain are adaptive or can be understood as by-prod

Som underlag för ett internationellt forskningssamarbete kring Paracaskulturen har Statens Museer för Världskultur givit mig i uppdrag att sammanställa en samlingshistorisk utredning av de svenska Paracassamlingarna. Utredningen skall sätta de samlingar som staden Göteborg äger (och som myndigheten förvaltar) samt statens egna samlingar i en historisk kontext och i förhållande till andra motsvaran
