In an optimal growth setting, where the only productive asset is a renewable resource which is jointly exploited, it is shown that competitively the resource may be over-used or under-used. The diversion from optimal use arises due to the externality embodied in the jointness of exploitation and would intuit over-use. Surprisingly, under-use has been derived as an equilibrium phenomenon by Dutt...

an iodide ion-selective pvc membrane sensor based on copper (π)-bis-nphenilsalicyldenaminatocomplex as a novel sensing material is successfully developed. theelectrode showed a good selectivity for iodide ion with respect to common inorganic anions. thesensor exhibited a good linear response with slope of _58.6 ± 0.4 mv per decade over theconcentration range of 5.0 × 10-6 to 1.0 × 10-1 mol l-1,...

We estimated analytical errors of the Calbiochem, Kallestad, Hyland, Meloy, Helena, and Beckman immunochemical methods for serum transferrin. Intermethod biases were determined by analysis of the "Reference Preparation for Serum Proteins" of the College of American Pathologists and by analysis of 106 patients' serum samples. We judged the acceptability of errors by comparing confidence limits f...

The presence of trace metal cadmium assay was investigated with a copper immobilized on a graphite carbon electrode (GPC), the modified property of which was determined with handheld voltammetric systems. Following the determination of the analytical stripping conditions of 0.45 V amplitude, 30 Hz frequency, -1.4 V initial potential, and 4.0 mV increment potential, only a 60-s experimental accu...
