Some properties of compounds in degrading bacteria are required for biodegradation of contaminants to higher performance. Those strains which have a high percentage of these features are more effective at biodegradation. The present experiments were designed to measure these parameters. In this study, measurement of cell surface hydrophobic-degrading bacteria was designed which oil was separate...

background and objectives: streptococcus pneumoniae, a major human pathogen, is closely related to the commensal species s. mitis and s. oralis. s. pneumoniae surface proteins are implicated in virulence and host interaction of this species, but many of them have recently been detected in s. mitis b6 in silico. we tested for the presence of such genes usinga set of eight s. mitis and eleven s. ...

phytoplankton communities play a significant role in the oceanic biological pump by forming the base of the trophic structure. increase in nutrients loading affects spatial and temporal distribution of phytoplankton. this study examined the phytoplankton community structure and ecological indices in relation to nutrients dynamics in both estuarine and oceanic areas of ramisi-vanga systems along...

protein secretory systems are found in all living organisms including gram negative bacteria, and eukaryotic cell’s organelles that are derived from these bacteria. unlike all other living organisms, gram negative bacteria have different protein secretory systems. at least there are four different independent secretory systems, which are responsible to transport the secreted proteins to the mil...

The osseointegration of oral implants is related to the early interactions between osteoblastic cells and titanium surface. Chemical surface modification of titanium (Ti) implants is used to improve peri-implant bone growth, bone-to-implant contact, and adhesion strength. Thus, in this study, the surface topography, chemistry, and biocompatibility of polished titanium surface treated with mixe...

We develop a general approach that uses holomorphic 1-forms to parameterize anatomical surfaces with complex (possibly branching) topology. Rather than evolve the surface geometry to a plane or sphere, we instead use the fact that all orientable surfaces are Riemann surfaces and admit conformal structures, which induce special curvilinear coordinate systems on the surfaces. Based on Riemann sur...

We developed a large cell culture surface with a nanostripe structure by paving polydimethylsiloxane (PDMS) replicas of a glass mold. The stripe structure has a height of 180 nm and top width of 500 nm with 400-nm intervals between stripes. Human stomach cancer SH-10-TC cells cultured on the surface changed their morphology to elongated shapes parallel to the nanostripes. In addition, cell moti...

Today, due to qualitative growth and scientific advances, energy, especially electricity is increasingly needed by human society. One of the almost endless and pure energy which have been paid attention over the years is the solar energy. Solar cells directly convert solar energy into electrical energy and are one of the main blocks of photovoltaic systems. Significant improvement has been made...

In this work, SiO2 –ZrO2 mixed oxides was prepared by the polymeric sol–gel route. The characterization of pore structure, which determines the permeation process of membrane, is of great importance. So far, most investigations have focused on such pore structure as specific surface area and pore size distribution, but the surface fractal, the important parameter reflecting the roughness of por...
