The article concerns with the prospects of using phenolphthalein test solution in practice surveying concrete and reinforced building structures planta. problem study is limits application on pH level determined (the indicator works only at 8≤rn≤10). There a need expanding application. In order to determine different zones we have modernize method by adding other indicators phenolphthalein. sta...

isolation of rat islets of langerhans was carried out by using collagenase and the destruction of exocrine tissue was performed through the injection of hanks' solution into the common bile duct. the identification of the islets was done by techniques including the use of a stereomicroscope against a black background. vital staining was done by an injection of neutral red solution through ...

This report presents an optimization of potentiometric measurements withcitrate-selective electropolymerized poly(neutral red) electrodes. The optimal backgroundelectrolyte for these measurements is a TRIS buffer with nitrate at pH 8.5. The electrodesdescribed here exhibit stable and reproducible near-Nernstian response to citrates with alow detection limit of 6 × 10-6 M. Electrodes polymerized...

The Atlantic jackknife clam, Ensis directus, is currently being researched as a potential species for aquaculture operations in Maine. The goal of this study was to describe the hemocytes of this species for the first time and provide a morphological classification scheme. We viewed hemocytes under light microscopy (using Hemacolor, neutral red, and Pappenheim's stains) as well as transmission ...

The red panda (Ailurus fulgens) has a similar diet, primarily bamboo, and shares the same habitat as the giant panda, Ailuropoda melanoleuca. There are considerable efforts underway to understand the ecology of the red panda and to increase its populations in natural reserves. Yet it is difficult to design an effective strategy for red panda reintroduction if we do not understand its basic biol...

Cadmium oxide rhombus-shaped nanostructure was synthesized using hydrothermal process followed by heating treatment. Clearly, X-ray diffraction pattern demonstrated the formation of CdO crystalline phase. Scanning electron microscopy (SEM) showed that the obtained rhombus-like structure is composed of nanoparticles with the average size of 29 nm. In addition, we evaluated adsorption of org...

Isolation of rat islets of Langerhans was carried out by using collagenase and the destruction of exocrine tissue was performed through the injection of Hanks' solution into the common bile duct. The identification of the islets was done by techniques including the use of a stereomicroscope against a black background.

The relationship between food flavors and postingestive feedback enables mammalian herbivores to procure nutrients and avoid toxins within ever-changing environments. We conducted four experiments with red-winged blackbirds (Agelaius phoeniceus) in captivity to determine the relative roles of color and flavor cues paired with negative postingestive feedback. We first conducted baseline tests to...
