C-band scatterometer and wind-field retrieval

Canadian Journal of Remote Sensing, 2003
The wind scatterometer is a microwave active sensor capable of simultaneously measuring the normalized radar cross section (?o) of the sea surface with high radiometric accuracy at different azimuth angles. The scattering process governing the electromagnetic wave - sea surface interaction allows these measurements to be related to the sea surface wind

Comparative cytogenetic analysis in Erythrolamprus snakes (Serpentes: Dipsadidae) from Argentina

Anais da Academia Brasileira de Ciências
We described the karyotypes of five snake taxa from Argentina: Erythrolamprus almadensis, E. ceii, E. poecilogyrus caesius, E. p. schotti and E. p. sublineatus, and also intergrading individuals between the last two subspecies by conventional staining ...

Karyotypic conservatism in five species of Prochilodus (Characiformes, Prochilodontidae) disclosed by cytogenetic markers

Genetics and Molecular Biology, 2013
The family Prochilodontidae is considered a group with well conserved chromosomes characterized by their number, morphology and banding patterns. Thence, our study aimed at accomplishing a cytogenetic analysis with conventional methods (Giemsa staining ...

Iris polarizer for extended C-band

, 2021
This article presents the design and characteristics of new wideband iris polarizer based on a square waveguide with diaphragms. Matching and polarization characteristics of the iris polarizer have been simulated and optimized. Frequency dependences of the simulated characteristics are presented.

Karyotype and chromosome banding of endangered crucian carp, Carassius carassius (Linnaeus, 1758) (Teleostei, Cyprinidae)

Comparative Cytogenetics, 2013
The karyotype and other chromosomal characteristics the crucian carp (Carassius carassius (Linnaeus, 1758)) were revealed by means of conventional banding protocols (C, CMA3, AgNOR). The diploid chromosome number (2n) in this species was 100.

Revisiting the Karyotype of the Social Wasp Polistes canadensis (Linnaeus, 1758) (Hymenoptera: Vespidae: Polistinae)

Brazilian Archives of Biology and Technology
Cytogenetic techniques have been improving over the last decades, providing useful information for the systematics and evolution of several groups, such as social insects. On the other hand, karyotypic data are still incipient for most wasp genera.
