caviar is one of the valuable and most popular fish products all over the world that are obtained from sturgeons. nowadays, the wild resources of these fishes are diminished, therefore, to meet the demand for the product, farming sturgeons has been considered. the chemical composition and the amino acids profiles of the wild and farmed roe obtained from beluga (huso huso) were compared and the ...

We address the problem of determining if a given image region contains people or not, when environmental conditions such as viewpoint, illumination and distance of people from the camera are changing. We develop three generic approaches to discriminate between visual classes: ridge-based structural models, ridge-normalized gradient histograms, and linear auto-associative memories. We then compa...

Solar-pointing Fourier transform infrared (FTIR) spectroscopy offers the capability to measure both the fine scale and broadband spectral structure of atmospheric transmission simultaneously across wide spectral regions. It is therefore suited to the study of both water vapour monomer and continuum absorption behaviours. However, in order to properly address this issue, it is necessary to radia...

This paper compares two solutions for human-like perception using two different modular “plug-and-play” frameworks, CAVIAR (List et al, 2005) and Psyclone (Thórisson et al, 2004, 2005a). Each uses a central point of configuration and requires the modules to be autodescriptive, auto-critical and auto-regulative (Crowley and Reignier, 2003) for fully autonomous configuration of processing and dat...

The cardiac action potential (AP) and the consequent cytosolic Ca(2+) transient are key indicators of cardiac function. Natural developmental processes, as well as many drugs and pathologies change the waveform, propagation, or variability (between cells or over time) of these parameters. Here we apply a genetically encoded dual-function calcium and voltage reporter (CaViar) to study the develo...

—During November 2002, 51 shovelnose sturgeon Scaphirhynchus platorynchus were sexed by ultrasound imaging using a portable ultrasonograph. We identified males with 96% accuracy (N 5 25) and females with 80% accuracy (N 5 25); one hermaphroditic individual was misidentified as a male. Overall, ultrasound imaging was 86% accurate. Sex in postspawned females was difficult to determine, 60% being ...

The simple answer to your burning question is no ? salt substitutes won?t make you retain water. As you mentioned, these substitutes contain potassium chloride instead of sodium chloride (more on this in a bit!). That said, before you completely eliminate salt from your diet, keep in mind that the average person does need 1500 milligrams (mg) to 2300 mg of salt per day for optimal kidney and mo...
