Scattered populations of Rüppell's foxes (Vulpes rueppelli) occur across the deserts of northern Africa and Arabia. Little is known about the biology of these canids, especially the physiological mechanisms that contribute to their ability to live in such harsh environments. For individuals from Saudi Arabia, we tested the hypotheses that Rüppell's foxes have a reduced basal metabolic rate and ...

A araruta ( Maranta Arundinaceae L.) é uma hortaliça não convencional com grande potencial econômico, mas pouco conhecimento quanto à sua nutrição mineral. O objetivo deste trabalho foi avaliar a produtividade e pós-colheita de 'comum' submetida diferentes fontes doses fertilizantes orgânicos. experimento em parcelas subdivididas disposto quatro blocos duas principais, cada dividida cinco subpa...

The spin torque ferromagnetic resonance (STFMR) is one of the popular methods for measurement Hall angle (SHA). However, in order to accurately determine SHA from STFMR measurements, acquired data must be carefully analyzed: linewidth should determined an accuracy a fraction Oe, while dynamical interaction leading measured response consists conventional field-induced (FMR), spin-torque induced ...

The present paper reviews recent studies on changes in body mass, body composition and rates of energy expenditure during the breeding season in the black-legged Kittiwake (Rissa tridactyla) on Svalbard (79 degrees N). The main characteristic of the energy budget is a pronounced decrease in body mass as well as basal metabolic rate (BMR) after the eggs have hatched. While most internal organs l...

Time-domain magnetization dynamics of sputtered GdFeCo (30 nm) amorphous alloy films was measured by pump-probe method using high-power ultra-short pulse fiber laser. The effective g-factor g and effective damping constant of the GdFeCo films were estimated by using a numerical calculation of Landau–Lifshitz–Gilbert equation. The precessional frequency took a maximum near the magnetization comp...

We investigate magnetization dynamics of Mn2Au/Py (Ni80Fe20) thin film bilayers using broadband ferromagnetic resonance (FMR) and Brillouin light scattering spectroscopy. Our exhibit two resonant modes with zero-field frequencies up to almost 40 GHz, far above the single-layer Py FMR. model calculations attribute these coupling FMR antiferromagnetic (AFMR) Mn2Au. The strength is in order 1.6 T ...

We analyze dispersion relations of magnons in ferromagnetic nanostructures with uniaxial anisotropy taking into account inertial terms, i.e. magnetic nutation. Inertial effects are parametrized by damping-independent parameter $\beta$, which allows for an unambiguous discrimination from Gilbert damping $\alpha$. The analysis magnon relation shows its two branches modified the effect, albeit dif...
