Dynamical disorder motivates fluctuating rate coefficients in phenomenological, mass-action rate equations. The reaction order in these rate equations is the fixed exponent controlling the dependence of the rate on the number of species. Here, we clarify the relationship between these notions of (dis)order in irreversible decay, n A → B, n = 1, 2, 3, …, by extending a theoretical measure of flu...

The rate coefficient of the reaction NHsX 3S−d+Hs2Sd→ k1a NsSd+H2sX Sg d is determined in a quasistatic laser-flash photolysis, laser-induced fluorescence system at low pressures s2 mbarø p ø10 mbard. The NHsXd radicals are produced via the quenching of NHsaDd sobtained by photolyzing HN3d with Xe whereas the H atoms are generated in a H2/He microwave discharge. The NHsXd concentration profile ...

Estimates of instrumental rules can be utilized to describe central bank's behavior and monetary policy stance. In the last decade, considerable attention has been given to time-varying parameter (TVP) specification of monetary policy rules. Constant-parameter reaction functions likely ignore the impact of model uncertainty, shifting preferences and nonlinearities of policymaker's choices. This...

The water storage capacity of a green roof generates several benefits for the building conterminous environment. hydrologic performance is conventionally expressed by runoff coefficient, according to international standards and guidelines. coefficient dimensionless number defines retention over long period. At scale single rain events, characterized varying intensity duration, reaction scarcely...

Isolated photosynthetic reaction center from the bacterium Rhodospirillum rubrum was extracted with acetone-methanol. Its main pigments were identified as bacteriochlorophyll, bacteriopheophytin, and spirilloxanthin. The extinction coefficients of these pigments in acetone-methanol were determined. Quantitative spectroscopic analysis of the dry acetone-methanol extracts indicated a bacteriochlo...

The absolute rate coefficient for the reaction of alpha-pinene with ozone was determined in the temperature range between 243 K and 303 K at atmospheric pressure. In total, 30 experiments were performed in the large (85 m3) temperature-controlled simulation chamber AIDA, where the concentrations of the reactants ozone and alpha-pinene were measured directly. An Arrhenius expression for the alph...

In this study, novel near-infrared and attenuated total reflectance mid-infrared spectroscopic methods coupled with multivariate data analysis were established enabling the determination of thymol, rosmarinic acid, and the antioxidant capacity of Thymi herba. A new high-performance liquid chromatography method and UV-Vis spectroscopy were applied as reference methods. Partial least squares regr...

Methods for combining 2×2 contingency tables from multiple studies are reviewed and new methods are proposed. Methods for combining 2×2 contingency tables from multiple studies are presented in the context of three different statistical models: the constant coefficient model, the varying coefficient model, and the random coefficient model. The constant coefficient confidence intervals have unac...

the purpose of this study is to evaluate the impact of self-fulfilling prophecy on the motivation and performance of national iranian gas company staffs. in this study, considering the importance of peoples’ perception and its role in motivation and consequently their performance in organization, we have tried to investigate the influence of one of these perceptual factors by using the correlat...
