This research was undertaken to investigate performance of high-strength concrete incorporating mineral admixtures, fly ash and silica fume. For modern construction, the use of new construction materials is increasing to achieve economy and improved final results. An extensive literature search was carried out to review various engineering properties of high-strength concrete. In this study, th...

Far-infrared spontaneous emission at 300 K and lower temperatures, due to intersubband transitions in self-organized In0.4Ga0.6As/GaAs quantum dots, has been characterized. Measurements were made with a multidot layer near-infrared ~;1 mm! interband laser. The far-infrared signal, centered at 12 mm, was enhanced after the interband transition reached threshold at 300 K. The results are explaine...

OBJECTIVES To examine whether the overall results of the CASTLE study pertain to both genders, we analysed the efficacy and safety of atazanavir/ritonavir and lopinavir/ritonavir in 277 female and 606 male patients in the open-label, multinational trial over 96 weeks. The trial is registered with ClinicalTrials.gov, number NCT00272779. METHODS Treatment-naive patients aged ≥ 18 years with HIV...

OBJECTIVE To investigate the chemopreventive effect of the hexane extract of Ardisia crispa during the peri-initiation phase of mouse skin tumorigenesis. MATERIALS AND METHODS This study was conducted for 12 weeks on two-stage 7,12-dimethylbenz(α)-anthracene (DMBA)-induced tumor initiation followed by croton-oil-induced tumor promotion in mice. A. crispa root hexane extract (ACRH) was applied...

Rat peritoneal macrophages were incubated in the presence of 0.05-1.0 mM-[14C]citrulline. The synthesis of [14C]arginine from 0.1 mM-[14C]citrulline was about 300 pmol/h per 10(6) cells in macrophages from saline-injected (control) rats. Both arginine synthesis from citrulline and nitrate production (an indicator of NO generation) were increased about 3-fold in the cells from lipopolysaccharide...

in order to compare forage and grain production of rye with barley, triticale and vetch under dry farming conditions, an experiment was conducted with eight treatments (including rye, wild rye, triticale, barley, as well as hungarian vetch mixed with rye, wild rye, triticale and barley) in a randomized complete block design with 3 replications in 3 years. in the first year, the highest forage a...
