Optical interferometers are commonly used for a variety of applications, including spectral analysis, displacement measurements, and gyroscopes. They were also proposed, in a more limited sense, for applications involving image processing.' In what follows we describe three new interferometers that implement mathematical operations on images borne by coherent input laser beams. Each interferome...

several therapeutic effects including hypnotic, antispasmodic, treatment of abdominal and chest pain and strengthening the heart have been described for the flowers of rosa damascena. north american indian tribes use a decoction of the roots obtained from the rosa damascena plant as a cough remedy and to treat eye problem. therefore, in the present study the antitussive effect of this plant in ...

The domesticated guinea pig, Cavia porcellus (Hystricomorpha, Rodentia), is an important laboratory species and a model for a number of human diseases. Nevertheless, genomic tools for this species are lacking; even its karyotype is poorly characterized. The guinea pig belongs to Hystricomorpha, a widespread and important group of rodents; so far the chromosomes of guinea pigs have not been comp...

Attempts to obtain experimental values for the kinetic parameters of phenanthridine oxidation by guinea pig or rabbit liver aldehyde oxidase using common spectrophotometric methods have not been successful due to a lower limit of detection. In the present study, a new spectrofluorimetric assay in combination with a multivariate calibration method for enzymatic kinetic study of aldehyde oxidase ...

Inhalational insulin was withdrawn from the market due to its potential to produce airway hyper-reactivity and bronchoconstriction. So the present study was designed to explore the acute effects of insulin on airway reactivity of guinea pigs and protective effects of salbutamol and beclomethasone against insulin induced airway hyper-responsiveness on isolated tracheal smooth muscle of guinea pi...

Rabbits immunized with partially purified guinea pig serum and guinea pig liver L-asparaginases produced precipitating antibodies to the homologous enzymes. Antisera to guinea pig serum L-asparaginase precipitated the guinea pig liver and agouti serum L-asparaginases but did not crossreact with Escherichia coli B L-asparaginase. Conversely, antisera to guinea pig liver L-asparaginase precipitat...

Following a familiar route and finding a novel route in a familiar environment depend on different cognitive processes and representations. A recent study by Hartley et al. begins to identity the neural basis of route following and wayfinding in humans. Their study also raises important questions about the functions of the hippocampus.

Reading a book is also kind of better solution when you have no enough money or time to get your own adventure. This is one of the reasons we show the teaching medical students in primary and secondary care a resource book as your friend in spending the time. For more representative collections, this book not only offers it's strategically book resource. It can be a good friend, really good fri...

This paper reports comparative analyses of phase noise in Hartley, Colpitts, and common-source cross-coupled differential pair LC oscillator topologies in 28 nm CMOS technology. The impulse sensitivity function is used to carry out both qualitative and quantitative analyses of the phase noise exhibited by each circuit component in each circuit topology with oscillation frequency ranging from 1 ...
