background: alpha particle irradiation from radon progeny is one of the major natural sources of effective dose in the public population. oncogenic transformation is a biological effectiveness of radon progeny alpha particle hits. the biological effects which has caused by exposure to radon, were the main result of a complex series of physical, chemical, biological and physiological interaction...

The paper offers basic elements of a new graphical model transformation language MOLA. The language combines the traditional structured programming with pattern-based transformation rules, the key element being a natural loop construct. The prime goal of MOLA is to provide a natural and highly readable representation of model transformation algorithms.

zeolites a, x and hs were synthesized from natural iranian kaolinite by alkaline fusion,,followed by refluxing the mixture. the transformation of zeolites x to hs and y to p were studied at different time intervals by x-ray diffraction and scanning electron microscopy (sem). it was revealed that in solution, zeolites hs and p are more stable than zeolites x and y respectively

Horizontal gene transfer plays a significant role in bacterial evolution and has major clinical importance. Thus, it is vital to understand the mechanisms and kinetics of genetic transformations. Natural transformation is the driving mechanism for horizontal gene transfer in diverse genera of bacteria. Our study introduces a simple and rapid method for the investigation of natural transformatio...

We give two versions of the natural extension of a specific greedy β-transformation with deleted digits. We use the natural extension to obtain an explicit expression for the invariant measure, equivalent to the Lebesgue measure, of this β-transformation.

the conceptual transformation of pre-modern era to modern times of natural rights philosophers rights issues which will be discussed below philosophical development beginning of the modern era. natural law in modern times, unlike many writers, ancient or medieval deemed not continue, but at the beginning of a new era in the world of thought which occurred as rotational different concepts of hum...

The mesophile Acinetobacter sp. strain BD413 and the extreme thermophile Thermus thermophilus HB27 display high frequencies of natural transformation. In this study we identified and characterized a novel competence gene in Acinetobacter sp. strain BD413, comA, whose product displays significant similarities to the competence proteins ComA and ComEC in Neisseria and Bacillus species. Transcript...
