background and objective: shigella species belong to the family enterobacteriaceae, which cause dysentery with abdominal pain and tenesmus in human. our country is one of the endemic and occasional epidemic areas of the disease. in the present study, repetitive extragenic palindromic polymerase chain reaction (rep-pcr) technique that has high differentiation and specificity power compared to ph...

Purpose. To formalize the dependence of eigenfrequencies translational and torsional vibrations structural elements vibrating machine articulated by connection node on their design parameters mechanical characteristics, as well regulatory requirements for vibration activity, strength accuracy. develop a method selecting elastic band element package, taking into account specified values amplitud...

one concern about using transgenic plants is the genetic variation that occurred from theirs tissue culture and regeneration. molecular markers are an important element for efficient and effective determination of genetic variation. the present work was carried out to assess the genetic uniformity of transgenic cottons (bt and chitinase lines), using rapd, issr molecular markers and sds-page an...

In this paper we proposed two new confidence intervals for the normal population mean with known coefficient of variation. This situation occurs normally in environment and agriculture experiments where the scientist knows the coefficient of variation of their experiments. We propose two new confidence intervals for this problem based on the recent work of Searls [5] and the new method proposed...
