protein memories are novel technologies which use the hidden abilities of bacteria proteins and biological molecules in order to the electronic processes. four decades before baceriorhdopsin ( br) protein was extracted from the membrane of halobacerinum salina rum found in high salt water depositions after its original discovery in 1967. in this study, for immobilizing the protein a film has be...

In the present paper, we study surfaces invariant under the 1-parameter subgroup in Sol space $rm Sol_3$. Also, we characterize the surfaces in $rm Sol_3$ whose coordinate functions of an immersion of the surface are eigenfunctions of the Laplacian $Delta$ of the surface.

The influence of surface roughness magnitude and direction on dry static friction coefficient between two similar steel samples has been studied through an experiment. A testing apparatus has been designed and fabricated to measure the friction coefficient for a few forms of surface asperity. According to the results of the experiments, dry friction coefficient is affected by both magnitude and...

background: ‍‍cryopreservation has some detrimental impacts on sperms surface molecules. modification of the sperm surface molecules can affect on fertility rate. one of the important surface molecules are glycoconjugates. objective: the objective of this study was to evaluate the changes of content of the glycocalyx after standard cryopreservation procedure. materials and methods: forty five h...

statement of the problem although the primary use of tissue conditioners is to treat abused mucosa, these materials are also frequently used as functional impression materials. insufficient information is available on the effect of these materials on the surface of dental stone casts. purpose this study evaluated the effect of a tissue conditioner (acrosoft) on surface roughness of dental stone...

background and objectives:   iranian chronic hbv carrier’s population has shown a unique pattern of genotype d distri- bution all around the country. the aim of this study was to explore more details of evolutionary history of carriers based on structural surface proteins from different provinces. materials and methods: sera obtained from 360 isolates from 12 different regions of country were u...

background: when provisional restorations are worn for long term period, the adhesion of bacteria becomes a primary factor in the development of periodontal diseases. the aims of this study were to evaluate the surface roughness and bacterial adhesion of four different provisional fixed prosthodontic materials. methods: ten cylindrical specimens were prepared from bis-acrylic composites (previs...
