all that we know about the life and times of al-sijzī, the 10th century iranian muslim mathematician and astronomer, is limited to the small pieces of information provided by other authors’ accounts and some of his own works. on the basis of al-sijzī’s mathematical works and the extant maunscripts written in his hand, some modern scholars have estimated his date of birth in about 942 ad. numero...

The major light-harvesting chlorophyll a/b-binding protein (Lhcb1,2) of photosystem II is inserted into the thylakoid via the signal recognition particle dependent pathway. However, the mechanism by which the protein enters the membrane is at this time unknown. In order to define some topographical restrictions for this process, we constructed several recombinant derivatives of Lhcb1 carrying h...

data collected confirmed the RNA-Seq results. ChIP-Seq methods are being optimized to identify the direct targets of OpaR. Select targets were confirmed direct targets via in vitro electrophoretic mobility shift assays (EMSA) with purified hexahistidine tagged OpaR. A previously published position specific weighted matrix (PSWM) will be utilized to assist in identification of possible OpaR bind...

rational explanation of the doctrine of imamat (spiritual leadership of the shi`ites) is one of the most important and efficient instruments that can prepare the ground for extension and propagation of this view in all over the world. so, in this article i want to study one of the first rational explanation of this view in islamic world which proposed by al- farabi. in the world of islam, farab...

The mutL gene product is part of the dam-directed mismatch repair system of Escherichia coli but has no known enzymatic function. It forms a complex on heteroduplex DNA with the mismatch recognition MutS protein and with MutH, which has latent endonuclease activity. An N-terminal hexahistidine-tagged MutL was constructed which was active in vivo. As a first stop to determine the functional doma...

Problem statement: The needs of computer forensics investigators have been directly influenced by the increasing number of crimes performed using computers. It is the responsibility of the investigator to ascertain the authenticity of the collected digital evidence. Without proper classification of digital evidence, the computer forensics investigator may ended up investigating using untrusted ...
