The microstructure, mechanical properties, and corrosion behavior of binary Ti-xPt alloys containing 5, 10, 15 and 20 wt% Pt were investigated in order to develop new Ti-based dental materials possessing superior properties than those of commercially pure titanium (cp-Ti). All of the Ti-xPt (x = 5, 10, 15, 20) alloys showed hexagonal α-Ti structure with cubic Ti₃Pt intermetallic phase. The mech...

We introduce the XPT approach for the automated systematic generation of XML instances which conform to a given XML Schema, and its implementation into the proof-of-concept tool TAXI. XPT can be used to automatize the black-box testing of any general application that expects in input the XML instances. We generate a comprehensive set of instances by sampling all the possible combinations of ele...

Here we report the nearly complete base assignments and partial sugar assignments of the 35-residue terminator hairpin of the Bacillus subtilis xpt-pbuX-mRNA guanine sensing riboswitch.

Plastids are the site of the reductive and the oxidative pentose phosphate pathways, which both generate pentose phosphates as intermediates. A plastidic transporter from Arabidopsis has been identified that is able to transport, in exchange with inorganic phosphate or triose phosphates, xylulose 5-phosphate (Xul-5-P) and, to a lesser extent, also ribulose 5-phosphate, but does not accept ribos...

To test the applicability of lichens in the biomonitoring of atmospheric elemental deposition in a typical steppe zone of Inner Mongolia, China, six foliose lichens (Physcia aipolia, PA; P. tribacia, PT; Xanthoria elegans, XE; X. mandschurica, XM; Xanthoparmelia camtschadalis, XPC; and Xp. tinctina, XPT) were sampled from the Xilin River Basin, Xilinhot, Inner Mongolia, China. Twenty-five eleme...

In Bacillus subtilis expression of genes or operons encoding enzymes and other proteins involved in purine synthesis is affected by purine bases and nucleosides in the growth medium. The genes belonging to the PurR regulon (purR, purA, glyA, guaC, pbuO, pbuG, and the pur, yqhZ-folD, and xpt-pbuX operons) are controlled by the PurR repressor, which inhibits transcription initiation. Other genes ...

(1−x)Pb(Mg1/3Nb2/3)-xPbTiO3 (PMN-xPT) ceramics with x ranging from 0.1 to 0.3 were synthesized by solid-state reaction method. X-ray diffraction, dielectric and ferroelectric property characterizations systematically investigated. As rises, the PMN-xPT transitions a cubic rhombohedral phase, resulting in an enhancement ferroelectricity. Our findings show that electrostrain longitudinal electros...

Xenorhabdus strains from entomopathogenic nematodes isolated from United Kingdom soils by using the insect bait entrapment method were characterized by partial sequencing of the 16S rRNA gene, four housekeeping genes (asd, ompR, recA, and serC) and the flagellin gene (fliC). Most strains (191/197) were found to have genes with greatest similarity to those of Xenorhabdus bovienii, and the remain...
