Solid phase spectrophotometry (SPS) provides effective methods to combine metal ion preconcentration and their spectrophotometric determination, by integrating the formation of colored complexes and their fixation on the surface of a solid support placed inside the measurement cell. The coupling between flow injection analysis (FIA) and SPS (FI-SPS) makes it unnecessary to reach equilibrium con...

ABSTRACT By fitting high-quality and simultaneous multiwavelength spectral energy distributions at multiple epochs with a one-zone leptonic jet model, we study the properties of three famous blazars: Mrk 421, 3C 454.3 279. In emitting electron are calculated by solving kinetic equations injection, escape, adiabatic radiative losses. To explore multidimensional parameter space systematically, em...

Two obelin mutants distinctly different in the color of bioluminescence were successfully applied to simultaneous detection of two analytes in a single well. The flash-type signals were triggered by single injection of Ca and were discriminated by the spectral and time resolutions. The technique was developed in a high-throughput format, and applied to simultaneous immunoassay of two gonadotrop...

Introduction: Anxiety is among the most common and treatable mental disorders. Adrenergic and cannabinoid systems have an important role in the neurobiology of anxiety. The elevated plus-maze (EPM) has broadly been used to investigate anxiolytic and anxiogenic compounds. The present study investigated the effects of intraperitoneal (IP) injection of cannabinoid CB1 receptor antagonist (AM251) i...

Thanks to its properties and production pathways, ethanol represents a valuable alternative fossil fuels, with potential benefits in terms of CO 2 , NO x soot emission reduction. The resistance autoignition necessitates an ignition trigger compression-ignition engines for heavy-duty applications, which the current study is diesel pilot injection. simultaneous direct injection pure as main fuel ...

Sensory-selective local anesthesia has long been a key goal in local anesthetic development. For example, it allows women to be pain-free during labor without compromising their ability to push. Here we show that prolonged sensory-selective nerve block can be produced by specific concentrations of surfactants-such as are used to enhance drug flux across skin-in combination with QX-314, a lidoca...
