We report on the lunar and solar measurements used to determine the changes in the radiometric sensitivity of the Sea-viewing Wide Field-of-view Sensor (SeaWiFS). Radiometric sensitivity is defined as the output from the instrument (or from one of the instrument bands) per unit spectral radiance at the instrument's input aperture. Knowledge of the long-term repeatability of the SeaWiFS measurem...
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
genetic diversity is the basis success of improving the quality and quantity of crops. recognizing of genetic diversity and genetic potential of each plant species in plant breeding is necessary. in this study genetic diversity of 30 lentil samples belonging to collection of the college of agriculture of krage were evaluated using rapd molecular markers. rapd products were scored for presence (...
A new global positioning system (GPS) antenna is proposed to cover the three GPS bands (L1, L2, and L5, namely 1575, 1227, and 1176 MHz) with the L5 band to be added after 2006. The developed antenna size is only 1 5 1 5 in aperture corresponding to 7 7 ( = free space wavelength) and 13 thick. Quadrature feeding is employed to ensure right-hand circular polarized (RHCP) radiation. The final min...
Genetic diversity of 12 lemon balm ecotypes was evaluated using agronomic traits as well as ISSR and RAPD markers. Results of analysis of variance showed high diversity among the studied ecotypes. Cluster analysis using UPGMA method grouped the ecotypes into three different groups based on the agronomic traits. Twelve ISSR primers created 106 polymorphic bands among the studied ecotypes. An ISS...
Rare-earth phosphates (REPO4) are regarded as one of the promising thermal/environmental barrier coating (T/EBC) materials for SiCf/SiC ceramic matrix composites (SiC-CMCs) owing to their excellent resistance water vapor and CaO–MgO–Al2O3–SiO2 (CMAS). Nevertheless, a relatively high thermal conductivity (?) REPO4 becomes b...
Two spectroscopic instruments, a 1/4 meter Ebert-Fastie spectrometer and a Michelson interferometer, were flown aboard the NCAR Electra during the ALOHA-90 campaign. These instruments were designed to carry out measurements of the brightnesses and rotational temperatures of the 02 Atmospheric (0-1) band and several OH Meinel bands simultaneously with sodium lidar observations. The spectrometer ...
