the object of the regional planning is optimum use of resource for the development of regions. one of the most important items in regional development is the recognition of spatial and economical structure of the region. middle sized cities, have the secondary role in the study of economical structure of the regions. global experiments demonstrate that lack of attention to the role of secondary...

Background: Formation of secondary structure such as DNA hairpins or loops may influence molecular genetics methods and PCR based approaches necessary for genetic engineering, in addition to gene regulation. Materials and Methods: A polymerase chain reaction with splice overlap extension (SOE-PCR) was used to create fully synthetic 1F5 chimeric anti-CD20 heavy- and light-chain genes. The chi...

In the present study we attempted to correlate the structure and function of the cry11a (72 kDa) and cry4a (135 kDa) proteins of Bacillus thuringiensis var israelensis. Homology modeling and secondary structure predictions were done to locate most probable regions for finding helices or strands in these proteins. The JPRED (JPRED consensus secondary structure prediction server) secondary struct...

Interaction between a structure under base excitation and heavy non-structural elements that it supports is significant in the seismic analysis and design of the structure. Heavy non-structural elements may slide/rock under base excitation, and this dynamic action affects the seismic behavior of the supporting structure. Hence, in this study, a numerical model was presented to describe the seis...

In the last five decades study on plant secondary metabolites have been increasing. Higher plants with a wide range of secondary metabolites have been very important in the search of new therapeutic agents. Flavonoids are most widely distributed secondary natural metabolites that found in plants which occuring in free forms or as glycosides with polyphenolic structure. In this study secondary m...
