Length-weight relationships (LWRs) are useful for calculating weight based on measurements of length. Here we provide LWRs 17 species fish from the rivers Vltava and Elbe in Czech Republic, Central Europe. The samples were collected by electrofishing May 2016 to August 2019. There far fewer riverine than lotic fish. All significant with r2 values ranging 0.99 European barbel (Barbus barbus) 0.9...

This paper describes a multi-scale modeling approach to compute the large-strain deformation of zirconium alloy cladding, which is of interest to the study of fuel rod behaviors in transient and accident conditions. A Visco-Plastic Self-Consistent (VPSC) polycrystal plasticity model representing polycrystals by weighted orientations of single crystals has been implemented as the constitutive la...

the length-weight relationships, (lwrs) were calculated for 14 fish species belonging to five families (cyprinidae, cobitidae, nemacheilidae, salmonidae, and gobiidae) collected from the tajan river, north of iran. significant length-weight relationships with high correlation coefficients were found for all species.

A standard method for solving coupled multiphysics problems in light water reactors is Picard iteration, which sequentially alternates between solving single physics applications. This solution approach is appealing due to simplicity of implementation and the ability to leverage existing software packages to accurately solve single physics applications. However, there are several drawbacks in t...

The nuclear fuel cycle can be truly closed by supp lementing today’s thermal reactors with fast reactors, which can use as fuel the heavy, fissionable isotopes that accumulate in thermal-reactor fuel. In a fully closed cycle, the waste for disposal consists only of fission products with trace amounts of actinides. Eliminating the transuranics reduces the heat load in the repository, increasing ...

In this study, the length-weight relationships (LWRs) and condition factors were estimated for 445 specimens belonging to three gobiid species viz. Ponticola bathybius (Kessler, 1877), Neogobius caspius (Eichwald, 1831) pallasi (Berg, 1916) from Southern Caspian Sea basin. Total length total weight of examined ranged 4.9-28.3 cm 0.64-263.4 g, respectively. The parameter b studied found between ...

The length-weight relationships (LWRs) are one of the most useful parameters for fishery management and have importance in fisheries science. present study describes four freshwater fish species from Asi River system (Hatay, Turkey), namely Cobitis anabelae Freyhof, Bayçelebi & Geiger, 2018, levantina Krupp Moubayed, 1992, Oxynamecheilus hamvii (Krupp Schneider, 1991) namiri 1991). A total ...
