the study investigates the possibility of sex determination of rainbow trout (oncorhynchus mykiss)using molecular screen for products monosex of populations. 35 caudal fin tissue samples wereobtained from karaj rainbow trout mature population and then genomic dna was extracted andmarker loci amplified. polymerase chain reaction (pcr) was setup based on two omyfa andomyfatu markers for amplifica...

the alginate was extracted with six different methods from iran south seacoast algae, sargassum sp, and the percentage yield of alginate was determined. we divided our methods to two groups including acidic extraction and non-acidic. in acidic methods, hcl and h 2 so 4 were used as a detergent in extraction process and cacl 2 was exerted in non-acidic treatments. all treatments compared with ea...

There is an asymmetry between the mass of the electric charges, for example proton and electron, can understood by the asymmetrical Planck Distribution Law. This temperature dependent energy distribution is asymmetric around the maximum intensity, where the annihilation of matter and antimatter is a high probability event. The asymmetric sides are creating different frequencies of electromagnet...

Contemporary information systems are generally built on the principle of segregation of data and processes. Data are modeled in terms of entities and relationships while processes are modeled as chains of events and activities. This situation engenders an impedance mismatch between the process layer, the business logic layer and the data layer. We discuss some of the issues that this impedance ...

When Archie Cochrane, Fred Moore and I conceived of trying to relate mortality in developed countries to measures of health service provision little did we imagine that it would set a hare running 20 years into the future. To us this was an amusing correlational study in the spirit of McKeown and Illich—those sceptics of medical prowess. That our work has been reprinted in two collections of ep...
