K-shell photoionization of O+ and O2+ ions: Experiment and theory
(
American Physical Society
, 2015 , Article)
Absolute cross sections for the single and double K-shell photoionization of carbon like O2+ and nitrogen like O+ ions were measured in the 526–620-eV photon energy range by employing the ion-photon merged-beam technique ...
Application of statistical experimental design for optimisation of bioinsecticides production by sporeless Bacillus thuringiensis strain on cheap medium
(
Sociedade Brasileira de Microbiologia - SBM
, 2014 , Article)
In order to overproduce bioinsecticides production by a sporeless Bacillus thuringiensis strain, an optimal composition of a cheap medium was defined using a response surface methodology. In a first step, a Plackett-Burman ...
TiO2 nanotubes with ultrathin walls for enhanced water splitting
(
Royal Society of Chemistry
, 2015 , Article)
We demonstrate, for the first time, the synthesis of titania nanotubes
with ultrathin (3–5 nm) wall thickness. As revealed by the incident
photon-to-current collection efficiency (IPCE) and electrochemical
impedance ...
Isolation of the Bacillus thuringiensis plasmid carrying Bacthuricin F4 coding genes and evidence of its conjugative transfer
(
The Journal of Infection in Developing Countries
, 2014 , Article)
INTRODUCTION:
Conjugation is an excellent natural mode of DNA transfer in vivo between bacteria, particularly when these conjugative elements carry technological traits such as bacteriocin encoding genes. In the present ...

Transcriptional and post-transcriptional control of adipocyte differentiation by Jumonji domain-containing protein 6
(
Oxford University Press
, 2015 , Article)
Jumonji domain-containing protein 6 (JMJD6) is a nuclear protein involved in histone modification, transcription and RNA processing. Although JMJD6 is crucial for tissue development, the link between its molecular functions ...
Born small, die young: Intrinsic, size-selective mortality in marine larval fish
(
Nature Publishing Group
, 2015 , Article)
Mortality during the early stages is a major cause of the natural variations in the size and recruitment strength of marine fish populations. In this study, the relation between the size-at-hatch and early survival was ...
Impacts of urbanization on the distribution of heavy metals in soils along the Huangpu River, the drinking water source for Shanghai
(
Springer Berlin Heidelberg
, 2015 , Article)
We investigated the horizontal and vertical distribution of heavy metals (Hg, Pb, Zn, Cu, Cd, As, Ni, and Cr) in soils in the water source protection zone for Shanghai to study the origins of these metals, their connections ...
