A high-resolution C-banding technique
Canadian Journal of Genetics and Cytology, 1986A high-resolution C-banding technique is described. The major advantages of this method are its simplicity and reliability. Because this technique allows the recognition of unusual C-band heteromorphisms, it can be very useful in population cytogenetic studies.Key words: karyotyping, banding (C), heterochromatin, high resolution.

Assessment of the Feasibility of GNSS in C-Band
26th International Communications Satellite Systems Conference (ICSSC), 2008There is an interest in exploring the possible use for GNSS applications of the frequency band 5000 – 5030 MHz. Considering the increasing number of GNSS systems sharing the Lband spectrum and the power flux density limitations affecting the GNSS reserved frequency bands, there is an interest to look at new frequency bands.

Measurement of C-bands in human chromosomes
Computers in Biology and Medicine, 1975Abstract A technique is presented for obtaining quantitative measurements of C-bands in human chromosomes using a computer-controlled microscope and scanner. Relative efficiencies of various procedures for C-band and chromosome area and integrated optical density measurement and the sources and extent of variance in C-band measurements, whether ...

Even-harmonic C-band modulator
IEEE Transactions on Microwave Theory and Techniques, 2005Direct modulation at microwave frequencies promises the advantages of compact size, low cost, and relatively simple system design. In this paper, a novel architecture of a direct-vector C-band modulator is described. In particular, a subharmonic mixer is used to overcome the high carrier leakage that is associated with conventional fundamental ...

Maize is one of the most important cereal crops to be extensively characterized cytologically. McClintock (1929) gave the first indication of heterochromatinous knobs within pachytene maize chromosomes. Proceeding from chromosome morphology and data on the location of knobs, she provided early identification of all maize chromosomes.

C-Banding of Plant Chromosomes
2016C-banding is used to differentially stain metaphase chromosomes in organisms having appreciable amounts of constitutive heterochromatin. Its primary benefits are that it is an inexpensive and a relatively fast method of identifying individual chromosomes and morphological or karyotypic variation, including large chromosomal rearrangements and ...

In-fiber pulse reshaping in the C-band [PDF]
2015 17th International Conference on Transparent Optical Networks (ICTON), 2015 We have investigated ultrashort parabolic pulse formation via passive nonlinear reshaping in commercially available normal dispersive optical fibers at 1550 nm. It was investigated parabolic pulse formation in the transient-state regime and in the steady-state regime. The most suitable fiber for pulse reshaping was found. We have shown that femtosecond

G and/or c-bands in plant chromosomes?
Journal of Cell Science, 1984ABSTRACT Similarities and differences become evident from comparisons of centromeric and noncentromeric banding patterns in plant and animal chromosomes. Similar to C and G-banding in animals (at least most of the reptiles, birds and mammals), centromeric and nucleolus-organizing region bands as well as interstitially and ...

C-band coherent direct synthesizer [PDF]
12th International Conference on Microwaves and Radar. MIKON-98. Conference Proceedings (IEEE Cat. No.98EX195), 2002 The principle of operation of a direct coherent synthesizer is described. Practical realisation and measurement results of the C-band synthesizer are presented. Good parameters such as small frequency steps, fast switching time and low phase noise level are obtained.

Giemsa C-banding of potato chromosomes
Canadian Journal of Genetics and Cytology, 1984An air-drying technique was developed that provided well-spread somatic metaphases of the potato Solanum tuberosum. With Giemsa C-banding, the individual chromosomes (x = 12) could be identified. Some bands are different from those in S. phureja. The technique provides a means to investigate structural differences between genomes.Key words: C-banding,
