Morphology Control of TiO Nanorods Using KBr Salt for Enhancing the Photocatalytic Activity of TiO and MoS/TiO Heterostructures. by Thiehmed, Zeineb A

“…The results revealed that the presence of KBr molecules affects the growth rate by suppressing the growth in the lateral direction and allowing for axial growth. This results in affecting the morphology by decreasing the diameter of the nanorods, and increasing the free space between them. …”

Influence of Fines on the Compressibility of Surface Sands in Kuwait by Al-Abdulmuhsen, Shaikhah A. N.

“…Moreover, with increasing fines, the compressibility increased as demonstrated by the larger values of Cc at all degrees of relative compaction except at 100% and that the coefficient of consolidation Cv decreased with increasing fines, which means that as the fines increase the time required to achieve a certain degree of consolidation will also increase.…”

Pilot-scale petroleum refinery wastewaters treatment systems: performance and microbial communities' analysis by Karray, Fatma

“…The reduction of the COD, BOD5, phenols, and the total petroleum hydrocarbon (TPH) reached 82.10%, 85.87%, 91.63%, and 81.11%, respectively at high hydraulic residence time (HRT = 10 days). Decreasing HRT to 5 and 2.5 days led to a decrease in the efficiency of the process and a decrease in biomass concentration was also observed (<1000 mg/l). …”

Signaling pathways activated by PACAP in MCF-7 breast cancer cells by Zibara, Kazem

“…In addition, PACAP increased the phosphorylation levels of STAT1, Src and Raf within seconds, confirming their involvement in early stages of PACAP signaling whereas maximal phosphorylation of AKT, ERK and p38 was reached 10 to 20 min later. Moreover, selective inhibition of Src or PI3K resulted in a significant decrease in the phosphorylation of ERK and AKT, but not p38, demonstrating that PACAP signaling follows Src/Raf/ERK and PI3K/AKT pathways. …”
