Single-crystal platinum nanorods with high aspect ratios and tunable length were fabricated on a large scale by a glycol-assisted one-step vacuum impregnation method, using mesoporous inorganic silica SBA-15 as the host.

Cadmium (Cd) is one of the most important heavy metals and its pollution causes toxic effects on plants and human beinges well. Glycine betaine (GB) is an osmoprotectant that its external application leads to decrease stress strains as well as heavy metal accumulation hazards. This experiment was conducted to study the effect of seed priming with GB on Cd reduction of damages in the black seed...

We investigated the ability to perceive the metric shape of elliptical cylinders. A large number of previous studies have shown that small perspective variations (< or =10 degrees) afforded by stereovision and by head movements fail to allow accurate perception of metric shape. If space perception is affine (Koenderink & van Doom, 1991), observers are unable to compare or relate lengths in dept...

A fundamental question in the field of mechanotransduction is how forces propagate inside a cell. Recent experiments have shown that a force of a physiological magnitude, applied via a focal adhesion, can propagate a long distance into the cell. This observation disagrees with existing models that regard the cell as a homogeneous body. We show that this "action at a distance" results from the i...

A sensitive and highly reproducible multiplexed primer extension assay is described for quantitative mutation analysis of heterogeneous DNA populations. Wild-type and mutant target DNA are simultaneously probed in competitive primer extension reactions using fluorophor-labeled primers and high fidelity, thermostable DNA polymerases in the presence of defined mixtures of deoxy- and dideoxynucleo...

It is undeniable that instability plays a significant role in the design of pipelines. Local buckles induced by excessive force on specific part of pipeline can locally reduce the collapse pressure of a pipeline and cause local failure. Periodic placement of buckle arrestors along the pipeline can ensure that collapse only effect the length of pipe between two arrestors on either side of the in...
