Resumen
Abstract Monochromatic measurement of albumin by the bromcresol green method leads to overestimation of albumin in the presence of heparin. The interference seems to be caused by fibrinogen, which, in the presence of heparin, produces an almost constant increase of the measuring signal over the whole range of suitable wavelengths (550 to 700 nm). The albumin overestimation can be eliminated by using a bichromatic modification. An application of this procedure for the automated analyzer RAXT, RA-1000 (Bayer Diagnostik, Technicon) is presented. We recommend using only bichromatic methods for alb

Nonlinear interaction between the magnon mode and the mechanical mode in a magnomechanical system is treated analytically where the magnon mode is coherently driven by a bichromatic microwave drive field consisting of a strong pumping field and a weak probe field and that works within a perturbative regime. Using experimentally achievable parameters, we show that the magnonic second-order sideband is generated and can be considerably enhanced by increasing the power of the pumping field.

Squeezing light is a critical resource in both fundamental physics and precision measurement. Squeezing light has been generated through optical-parametric amplification inside an optical resonator. However, preparing the squeezing light in an optomechanical system is still a challenge for the thermal noise inevitably coupled to the system. We consider an optically levitated nano-particle in a bichromatic cavity, in which two cavity modes could be excited by the scattering photons of the dual tweezers, respectively.

This paper presents numerical modelling of the nearshore transformation of infragravity waves induced by bichromatic wave groups over a horizontal and a sloping bottom. The non-hydrostatic model SWASH is assessed by comparing model predictions with analytical solutions over a horizontal bottom and with detailed laboratory observations for a sloping bottom. Good agreement between model predictions and data is found throughout the domain for bound infragravity waves.

Fusarium head blight (FHB) is a fungal disease that affects small cereal grains, such as wheat and barley, and is becoming more prevalent throughout much of the world's temperate climates.

Resumen
We report measurements of counting statistics, average and variance, of microwave photons of ill-defined frequency: bichromatic photons, i.e., photons involving two well separated frequencies, and “white” broadband photons. Our setup allows for the analysis of single photonic modes of arbitrary waveform over the 1–10 GHz frequency range. The photon statistics are obtained by on-the-fly numerical calculation from the sampled time-dependent voltage. Using an ac+dc biased tunnel junction as a source of quantum microwave, we report an ultrawide squeezing spectrum representing a competitive source

Resumen
Since the work of Stokes on steady progressive surface waves (Stokes, 1847), there has been interest in fluid particle trajectories and associated mass flux. The original result obtained by Stokes was based on linear theory, and implied that there is a net forward drift in the fluid beneath a propagating surface wave. In the non-dimensional case, the drift velocity for a sinusoidal wave on a fluid of depth h is given by Recent works suggest that in many cases, particularly in waves propagating over a shear flow, a net Eulerian flow may develop, which is opposed to the Stokes drift.

Resumen
Coherent population trapping (CPT) oscillation is a transient oscillation phenomenon based on the CPT effects, which is related to the Raman detuning of the coherent bichromatic laser fields from the hyperfine ground-states of three-level Λ system. In this work, sawtooth wave is adopted to modulate the frequency of microwave signal to make Raman detuning change uniformly and stepping. Meanwhile, by building the relationship between the microwave frequency modulation rate and the change rate of Raman detuning, the effects of the change rate and mode of Raman detuning on CPT oscillation are anal

Resumen
Abstract: Onshore bar migration is a characteristic bar behavior during post-storm beach recovery. The present large-scale experiments, feature bichromatic wave groups over an initially steep (1:15), fully-evolving beach. The same accretive wave condition is applied on two different post-storm beach profiles featuring outer and inner bars. They are characterized by a larger (smaller) shoreline erosion and a larger (smaller) outer breaker bar located farther away from (closer to) the shoreline depending on the larger (smaller) energy of the storm condition. After a considerable post-storm recov

Resumen
Such compounds as compounds of hexavalent chromium, nitrates and nitrites are one of the most distributed pollutants of the environment. The compounds of Cr (VI) are found in the soil, water and territories adjacent to mining enterprises in elevated concentrations. The hexavalent chromium has toxic, mutagenic and carcinogenic effect on living forms. Some sulfur-reducing bacteria are attractable for scientists attention like potential purification agentsto clear the wastewater from organic and inorganic pollutants. In this way,the purpose of our work is to study the patterns of the reduction of
