To investigate alternative routes to develop YY males and to examine some of the factors responsible for departures from predicted sex ratios in the Nile tilapia (Oreochromis niloticus), YY males were produced (i) by androgenesis from XY male parents

We present a method for applying optimal filtering to data sets containing energy-dependent pulse shapes. This occurs frequently in transition edge sensors (TES) when dealing with signal energies that are close to the saturation point of the detector

This paper describes hormonal masculinisation of genetically female, gynogenetic silver barbs ( Puntius gonionotus ) and the results of crosses between such neomales and ordinary females. Gynogenetic fish (previously shown to be all females) were use

A tin-polyimide and an indium-polyimide soft X-ray bandpass filter were fabricated with thicknesses of 1400 and 1750 A for the metal and polyimide components, respectively. The transmission of each filter was measured at the Stanford Synchrotron Radi

We are developing a new sounding rocket payload, the Advanced Technology Solar Spectroscopic Imager (ATSSI), that will use an 8 X 8 array of transition edge sensors (TES) to obtain true spectroheliograms in a spectral bandpass spanning approximately

Androgenesis is a potentially valuable technique for recovering fish from gene banks composed of cryopreserved sperm, developing inbred lines, and analyzing patterns of inheritance. The procedure for producing diploid organisms whose nuclear DNA is w

In this paper we address possible causes for inconsistencies in bulge test results and describe methods by which the bulge test technique can be made to produce accurate and reliable results. Experiments have been conducted on a variety of materials:

The multilayer mirrors used in the nonnal incidence optical systems of the Multi-Spectral Solar Telescope Array (MSSTA) are efficient reflectors for soft x-ray/extreme ultraviolet (EUV) radiation at wavelengths that satisfy the Bragg condition, thus

Acrylate-based optical waveguides have been fabricated with optical loss of 0.5 dB/cm at 1300 nm by means of a new material system that ensures stable optical and mechanical properties over a wide temperature range. No increase in loss was measured a
