Crystalline surface layer proteins (S-layer proteins) have considerable potential for the crystalline arrays in biotechnology, biomimetics and nonlife applications, including areas such as microelectronics and molecular nanotechnology. The extensive application potential of surface layers in nanobiotechnology is according to the particular inherent attributes of the single molecular arrays cons...

introduction thunderstorms pose a significant threat to modern societies and their assets. despite their local-scale characteristics, severe thunderstorms and associated extreme events like heavy rainfall, hail, gusts, or tornadoes can cause considerable damage to agriculture, buildings, or infrastructure, and facilities. thunderstorms are highly localized and largely stationary weather systems...

the main objective of this project was to investigate the behavior and the damaging effects of hot tear segregationsin the continuously cast steel blooms on the final product quality. to achieve this aim, plant data from three differenttypes of steels were used. investigations using the scanning electron microscope (sem) equipped with energydispersive x-ray spectroscopy (eds) probe and metallog...

intracranial gliosis has no typical clinical signals or imaging characteristics. therefore, it can be easily misdiagnosed as neoplasm. hereby, we report a unique case of gliosis that grew outward from the surface of the brain. mri depicted its signal and enhancement pattern similar to the cerebral gray matter. the diagnosis was confirmed by pathology and immunohistochemistry. although it was di...

Among various practical measures used for restriction of the ground surface settlement in such tunnels driven in soft ground, selection of an appropriate excavation method plays a significant role. In this paper, employing suggested diagram by Yu & Chern, corresponding values of Niayesh tunnel has been inserted into the diagram. Later, two excavation methods namely: central diaphragm and side d...

Purpose: The aim of this study was to assess the surface roughness, and fracture pattern zirconia ceramic restorations after application different treatments.
 Material method: We conducted a systematic literature search on electronic databases PubMed Science direct using 12 key words via Boolean equations. identified articles that met eligibility criteria by checking title abstract. A ful...
