In this study, deoxyribonucleic acid (DNA) solution effect on the Purcell factor of an electric dipole antenna was analyzed. Any tuned to a resonance can be described as radiator, and environment its radiation defined factor. It is possible determine in terms real part input impedance. Therefore, presence pure water DNA calculated through measuring impedance with frequency 9.6-11.6 GHz. The mea...

Plant nuclei have been studied with respect to the three-dimensional structure of DNA. Nucleoids derived from nuclei by non-ionic detergent and high salt treatment were analysed by sedimentation in a series of sucrose gradients containing increasing amounts of the intercalating agent ethidium bromide. In addition the nucleoid sedimentation behaviour was investigated following gamma irradiation....

this research was done in order to submit a model for salinity map made with tm satellite data and salinity values in a buienzahra. the necessary processings such as principal component analysis and producing of different indices was done on the main bands. the 38 soil samples using random sampling (with 10×10 km dimension) from different horizons were designed and performed on the study area. ...

Size variations in homologous chromosomes from six Giardia lamblia isolates have been demonstrated. Four or five intensely stained (major) bands as well as a variable number of lightly stained (minor) bands are present in pulsed field gradient separations. Southern blot analysis with total chromosomal DNA as well as chromosome specific probes indicates that each minor band cross-hybridizes with...

The red palm weevil, Rhynchophorus ferrugineus , is the most harmful species among those pests affecting trees. Its impact causes important economic losses around World. Nevertheless, genetic information of Rh. very scarce. Last year, first genome assembly was published including a rough description its repeatome. However, no has been added about one main components repeated DNA, satellite DNA....

BACKGROUND Suicide rates generally increase with age. A recent cross-national study, using one-year cross-sectional data on suicide rates identified regional and cross-national patterns for elderly suicide rates. However, findings from studies using one-year cross-sectional data on suicide rates may be open to bias because of random year on year fluctuations in elderly suicide rates. METHODS ...

The optical spectrum in the visible and near ultraviolet [ 1 ] has been one of the most widely used tools in the study of proteins. The heme moiety, the active site of the hemoprotein, absorbs strongly the visible radiation, and usually presents three optical bands, (Y, /3 and y. These bands are attributed to electronic transitions of the porphyrin ring. There are also other bands, such as the ...

| This paper examines the potential uses of interband leakage in image coders based on subband decomposition. The approach taken is to use the lowpass subband to predict the signal behavior in the other bands. This information is then used to both inform the coder/decoder as to likely locations for signi cant energy in the highpass bands, and to form a di erence signal that can be coded at a lo...

A coupled chromogenic reaction (based on an agar overlay combining NADH, pyruvate kinase, lactate dehydrogenase, phosphoenolpyruvate, ATP, and kanamycin sulfate with thiazolyl blue-phenazine methosulfate for detection of NADH consumption) was optimized for the detection of aminoglycoside phosphotransferases (APHs). When used after analytical isoelectrofocusing of bacterial extracts from APH-pro...
