In the Theory of Challenge and Threat States in Athletes (TCTSA) it is proposed that on approach to motivated performance situations an individual can respond in a challenge state or a threat state. Challenge and threat states are marked by contrasting patterns of psychological, emotional, and cardiovascular (CV) responses. A challenge state is proposed to maintain or facilitate performance com...

Speciation behavior of trihalomethanes formation in chlorinated waters due to the effects of bromide is mathematically modeled by a three-tier scheme. Equations for the mole fractions of the mono-, di-, and trihalo-intermediates at each tier level in terms of the initial bromide to chlorine molar ratio are derived and verified by comparison with results of other theoretical studies based on an ...

Inland waters play a critical role in the carbon cycle by emitting significant amounts of land-exported to atmosphere. While gas emissions from individual aquatic systems have been extensively studied, how networks connected streams and lakes regulate integrated fluxes organic inorganic forms remain poorly understood. Here, we develop process-based model simulate fate terrestrial dissolved (DOC...

This is a research report of the effects process variables on reactivity slaked lime produced from Shuk quicklime. It involved calcination (at temperature 1000 0C, particle size 90 µm and time 3 hrs) limestone subsequent slaking its The quicklime was characterized by x-ray diffractometer (XRD) scanning electron microscopy (SEM) respectively to determine mineral content surface morphology respec...

This article gives an overview of recently published literature on the factors that govern SN2 reactivity. By comparing reactivity in solution with that in the isolated gas phase, it has become possible to dissect the contribution of the solvent from that of the intrinsic molecular properties. This has proven to be an extremely important and fruitful step forward in obtaining key knowledge not ...

Preparations of purified immunoglobulins, light chains, and unrelated proteins (used as controls) were covalently linked to agarose beads and used to study the specificity of fluorescein isothiocyanate conjugates. The data demonstrate how these beads can be used to detect immunological and non-immunological reactivity in conjugates. Commercial conjugates, conjugates prepared in this laboratory,...

Drugs-of-abuse may increase the salience of drug cues by sensitizing the dopaminergic (DA) system (Robinson and Berridge, 1993), leading to differential attention to smoking stimuli. Event-related potentials (ERPs) have been used to assess attention to smoking cues but not using an ERP component associated with DA-mediated salience evaluation. In this study the DA-related P2a and the P3, were c...
