Evaluation of genetic variability of the breed Norik of Muran according to pedigree information
draught horse interbreeding local breed gene origin
2018/11/23
The Norik of Muran, a unique draught horse bred in Slovakia, belongs to country’s biodiversity treasures. The genetic diversity of this horse type was evaluated on the basis of indicators derived from...
Variability in the cardiometabolic effects of ω-3 long-chain PUFAs: background diet, timing, and genetics
Variability cardiometabolic ω-3 long-chain genetics
2018/11/13
Omega-3 long-chain PUFAs (LC-PUFAs) have received considerable attention over many years for their proposed health benefits, particularly in relation to cardiovascular disease. More recently, there ha...
Impact of interspecific hybridization of T. pratense × T.medium and backcrossing on genetic variability of progeny
cytology FISH hybrids rDNA red clover zigzag clover
2016/12/8
Red clover (Trifolium pratense L.) is a high-quality fodder crop which has been hybridized successfully with its wild relative zigzag clover (T. medium L.). The aim of this study was to evaluate the g...
Estimating the reliability of glycemic index values and potential sources of methodological and biological variability
glycemic index variability healthy volunteers insulin index glycated hemoglobin
2018/12/18
Background: The utility of glycemic index (GI) values for chronic disease risk management remains controversial. Although absolute GI value determinations for individual foods have been shown to vary ...
Coastal upwelling is linked to temporal genetic variability in the acorn barnacle Balanus glandula
Balanus glandul Upwelling Reproductive sweepstakes
2015/12/11
Dispersal and recruitment are central processes that shape the geographic and temporal distributions of populations of marine organisms. However, significant variability in factors
such as reproducti...
Marine reserves help preserve genetic diversity after impacts derived from climate variability: Lessons from the pink abalone in Baja California
Marine reserve Overfishing
2015/12/11
Genetic diversity is crucial for the adaptation of exploited species like the pink abalone
(Haliotis corrugata), faced with threats from climate change, overfishing and impacts
associated with aquac...
Antipersistent dynamics in short time scale variability of self-potential signals
Fractal propeties variogram analysis antipersistence self-potential signal earthquake prediction
2015/9/28
Time scale properties of self-potential signals are investigated through the analysis of the second order structure function (variogram), a powerful tool to investigate the spatial and temporal variab...
Coupling from below as a source of ionospheric variability: a review
Lower atmosphere ionospheric response waves thermosphere
2015/9/25
The purpose of this paper is to review shortly some observational backgrounds for the suggestion of a genuine link between processes in the lower atmosphere and ionospheric response. Attention is conc...
The effects of f0 F2 variability on TEC prediction accuracy
ionopshere ionospheric modelling
2015/9/25
In this paper hourly daily F2-layer critical frequency data recorded at Rome and one minute daily TEC data recorded at Florence were used and the relevant variabiles were calculated. It was concluded ...
Proposed terminology for the classification and parameters for the quantification of variability in ionosphere morphology

2015/9/25
Much uncertainty currently exists in the use by different workers of the term ?variability? in describing the results of statistical analyses applied to ionospheric measurement data sets and in their ...
Spatial and temporal analysis of the seasonal and interannual variability in the tropical Pacific simulated with a coupled GCM
coupled model El Nino-Southern Oscillation seasonal interannual heat content clusters
2015/9/17
In the first part of this work, the dominant time scales that explain the tropical variability of the first SINTEX simulation (ECHAM4(T30)-ORCA) are identified through a spectral analysis. Higher orde...
Influence of the North Atlantic on simulated atmospheric variability
atmospheric general circulation model internal/external variability climate predictability teleconnections
