Ultrafast Structural Dynamics of BlsA, a Photoreceptor from the Pathogenic Bacterium Acinetobacter baumannii [PDF]

open access: yes, 2014
Acinetobacter baumannii is an important human pathogen that can form biofilms and persist under harsh environmental conditions. Biofilm formation and virulence are modulated by blue light, which is thought to be regulated by a BLUF protein, BlsA.

EFFECT OF RESIDUAL EFFECTIVE ALKALI ON EUCALYPTUS KRAFT PULP YIELD AND CHEMISTRY [PDF]

open access: yesCERNE, 2018
ABSTRACT The impact of residual effective alkali (REA) and pulp delignification degree on Eucalyptus kraft pulp yield and chemistry was investigated. In this study four types of eucalypt clones were evaluated. The eucalypt woods were cooked to kappa numbers of 14±1, 18±1, 22±1 and 26±1 using two different ranges of REA, namely: low-REA (1-2 g.L-1) and ...

Mineral Concentrations in Different Types of Honey Originating from Three Regions of Continental Croatia

open access: yesFoods
Honey has been recognized as a reliable indicator of environmental quality because of honeybees’ intense foraging activity, which brings them into contact with many persistent organic pollutants around the hive. In this study, four types of honey (meadow,

Fast and Selective Degradation of Biomass for Xylose, Glucose and Lignin under Mild Conditions

open access: yesMolecules, 2023
The conversion of lignocellulose into valuable chemicals has been recognized as the key technology in green chemistry. However, selective degradation of hemicellulose and cellulose with the production of lignin is still a challenge. Therefore, a two-step

Growth, yield and fiber quality characteristics of Bt and non-Bt cotton cultivars in response to boron nutrition

open access: yesJournal of Cotton Research, 2023
Background Boron (B) deficiency is an important factor for poor seed cotton yield and fiber quality. However, it is often missing in the plant nutrition program, particularly in developing countries.

Length-Dependent Transition from Extended to Folded Shapes in Short Oligomers of an Azetidine-Based α-Amino Acid: The Critical Role of NH···N H-Bonds

open access: yesMolecules, 2023
Hydrogen bonds (H-bonds) are ubiquitous in peptides and proteins and are central to the stabilization of their structures. Inter-residue H-bonds between non-adjacent backbone amide NH and C=O motifs lead to the well-known secondary structures of helices,

Phase Chemistry of Tank Sludge Residual Components [PDF]

open access: yes, 2000
About four or five distinct reprocessing technologies were used at various times in Hanford's history. After removing U and Pu (or later 137Cs and 90Sr), the strongly acidic HLW was ''neutralized'' to high pH (>13) and stored in steel-lined tanks. High pH was necessary to prevent tank corrosion. While each technology produced chemically distinct waste,

Effect of charged lipids on the ionization behavior of glutamic acid containing transmembrane helices [PDF]

open access: yes, 2020
Transmembrane proteins make up critical components of living cells. Protein function can be greatly impacted by the charged state of its respective components, the side chains of amino acid residues.
