micrornas (mirnas) are short, endogenous non-coding rnas that function as guide molecules to regulate transcription of their target messenger rnas. several methods including low-density qpcr arrays are being increasingly used to profile the expression of these molecules in a variety of different biological conditions. reliable analysis of expression profiles demands removal of technical variati...

background: xanthomonas citri subsp. citri (xcc), the causative agent of bacterial citrus canker, has affected citriculture worldwide. varieties of means have been used to minimize its devastating effects, but no attention has been given to bacteriocins.objectives: here and for the first time, we report the isolation and characterization of two novel bacteriocins.materials and methods: secretom...

Laminar free convection heat transfer from vertical and inclined arrays of horizontal isothermal cylinders in air was investigated experimentally and numerically. Experiments were carried out using Mach-Zehnder interferometer and the FLUENT code was used for numerical study. Investigation was performed for vertical and horizontal cylinder spacing from 2 to 5 and 0 to 2 cylinder diameters respec...

One of the major disadvantages of using Branch and Bound algorithm to solve permutation bases problems by computer is the size of main memory required. The single Array Branch and Bound (SABB) method introduction here aims to overcome this deficiency, using only N memory locations as a vector of size N, and a single cell C with N bits.
