An external force-assisted near-field illumination biosensor (EFA-NI biosensor) detects a target substance that is propelled through an evanescent field by an external force. The target substance is sandwiched between an antibody coupled to a magnetic bead and an antibody coupled to a polystyrene bead. The external force is supplied by a magnetic field. The magnetic bead propels the target subs...

AIMS To apply item response mixture modelling (IRMM) to investigate the viability of the dimensional and categorical approaches to conceptualizing alcohol and cannabis use disorders. DESIGN A cross-sectional survey assessing substance use and DSM-IV substance use disorders. SETTING AND PARTICIPANTS A household survey of a nationally representative sample of 10,641 Australia adults (aged 18 ...

How does it happen that the proteids, carbohydrates and fats which ordinarily are oxidized by atmospheric oxygen at a very slow, or almost imperceptible rate, combine with oxygen with great rapidity in living matter? To answer this question I made the hypothesis that the total consumption of oxygen by the protoplasmic mixture is the sum of the consumptions of the various substances composing th...

Testing and assessing the persistency, bioaccumulative toxic properties of UVCBs (substances Unknown or Variable composition, Complex reaction products Biological materials) pose major technical analytical challenges. The main aim this study was to combine whole substance biodegradation testing with constituent specific analytics for determining primary kinetics UVCB constituents. An additional...

Diethylethanolamine derivativetablets, manufactured by direct compression, do not possess adequate quality attributes. Granulation of excipients makes it possible to improve the fluidity mixture and increase shelf-life tablets, however organization technological process in production is expensive. Melt extrusion stability substance obtain high-quality tablets with a 2 years. This approach prefe...

Continuous exposure to an aversive mixture was investigated as a means of maintaining aversion to vermeerbos in sheep subjected to the social influence of non-averted sheep. The use of an aversive mixture was based on a hypothesis that continuous exposure to an acceptable aversive mixture (containing both the aversive substance and the identification factors of vermeerbos mixed with maize meal)...

A theory is proposed that combines the most basic features of conformal solution theory and scaled particle theory (SPT) . The treatment in essence provides a means for evaluating mixture properties from pure fluid data; however, two intermediate substances-the “infinitely polydisperse” (IP) mixture and the “one-and-a-half fluid”-are used to implement the mapping. Associated with the IP mixture...

Mixture toxicity of similar- and dissimilar-acting toxicants can be predicted by the models concentration addition (CA) and independent action (IA) using single substance toxicity data. Knowledge of the toxicants mode of action is thus required in order to use the models. In order to test the predictive capability of the models, we conducted Daphnia magna 48 h immobilization experiments with th...
