Periodic radio bursts from very low mass stars and brown dwarfs simultaneously probe their magnetic and rotational properties. The brown dwarf 2MASSI J1047539+212423 (2M 1047+21) is currently the only T dwarf (T6.5) detected at radio wavelengths. Previous observations of this source with the Arecibo observatory revealed intermittent, 100%-polarized radio pulses similar to those detected from ot...

Polyphenols are widely used in drilling fluid, cement slurry and water treatment oil fields. The paper is based on the characteristics of abundant phenolic hydroxyl groups plant polyphenol compounds that can form stable complexes with iron ions, forming blueviolet to brown salts, color salts itself for light yellow, a method designed evaluate quality polyphenols, which provides simple reliable ...

We consider expected performances based on max-stable random fields and we are interested in their derivatives with respect to the spatial dependence parameters of those fields. Max-stable fields, such as Brown–Resnick Smith very popular extremes. focus two most unbiased stochastic derivative estimation approaches: likelihood ratio method (LRM) infinitesimal perturbation analysis (IPA). LRM req...

We present Very Large Array observations of twelve late M and L dwarfs in the Solar neighborhood. The observed sources were chosen to cover a wide range of physical characteristics — spectral type, rotation, age, binarity, and X-ray and Hα activity — to determine the role of these properties in the production of radio emission, and hence magnetic fields. Three of the twelve sources, TVLM 513-46...

Background: Fish meat is outlined with high nutritional value having essential amino acids, unsaturated fatty acids, mineral and vitamins. In this short report, we compared the meat quality of rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta fario) farmed in Bulgaria. Methods: Ten fishes from each species were purchased from a fish farm and their morphological parameters were ...

Spatial Bayesian clustering algorithms can provide correct inference of population genetic structure when applied to populations for which continuous variation of allele frequencies is disrupted by small discontinuities. Here we review works which used Bayesian clustering algorithms for studying the Scandinavian brown bears, with particular attention to a recent method based on hidden Markov ra...

State-of-the-art data analysis in production allows engineers to characterize reservoirs using production data. This saves companies large sums that should otherwise be spend on well testing and reservoir simulation and modeling. There are two shortcomings with today’s production data analysis: It needs bottom-hole or well-head pressure data in addition to data for rating reservoirs’ characteri...
