GUSTAVO OLIVEIRA: Comparison among ACP, Fluoride and a combination of ACP/ Fluoride and their ability to remineralize white spot lesions in vitro (Under the direction of Timothy Wright) This study evaluated the ability of a casein-phosphopeptide amorphous-calcium-phosphate paste (CPP-ACP, MI Paste™), a 1.1% NaF toothpaste containing 5000 ppm of fluoride (ControlRX™) and a CPP-ACP paste with 900...

This paper describes the development of screen-printed (SPE) and carbon paste (CPE) sensors for the rapid and sensitive quantification of naphazoline hydrochloride (NPZ) in pharmaceutical formulations. This work compares the electroactivity of conventional carbon paste and screen-printed carbon paste electrodes towards potentiometric titration of NPZ. The repeatability and accuracy of measureme...

This study was performed to investigate the effects of pre-treatment and storage temperature and periods on the quality characteristics of ginger paste. The pH of the ginger paste remained constant during room temperature storage but increased with prolonged refrigerated storage periods. During five months of frozen storage, regardless of pre-treatment, the pH of most of the samples decreased s...

That a crisis exists in the production of humanities Ph.D.s hardly seems worth restating. With the widespread use of adjunct professors and overworked graduate students, fewer and fewer Ph.Ds are finding full-time gainful employment. We have all heard the stories of part-time professors rushing from campus to campus, hoping to paste together a living. Few of them have health care benefits; rare...

Fresh water deficiency caused by climate change calls for employing novel measures to ensure safety of drinking water supply. Wireless sensor networks can be used for monitoring hydrological conditions across wide area, allowing flow forecasting and early detection of pollutants. While there are no fundamental technological obstacles to implementation of large area sensor networks, their feasib...

Controlled low strength material (CLSM) is gaining increasing importance with the growing emphasis on sustainability in construction industry. CLSM can be a valuable application for the safe and efficient use of nonstandard materials such as industrial by-products, which are normally rejected for conventional concrete due to the negative impact on hardened properties. In the present study, a la...

Adsorption of sodium diclofenac was investigated in the presence of sucralfate--a cytoprotective agent preventing gastropathy, adverse effect of diclofenac. Evaluation of adsorption was performed by means of a static method in vitro taking into account pH of the environment, temperature, concentration of the investigated agents and the form of sucralfate. Findings obtained prove that sodium dic...

Adsorbance of certain prokinetic drugs, regulating the motility of the digestive tract, on a cytoprotective drug--sucralfate was investigated. The evaluation of adsorbance capability was carried out by means of a statistical method in in vitro conditions, taking into account environmental pH, concentration of the investigated drugs as well as the form of sucralfate. Obtained results prove that ...

Cereal Chem. 70(2):137-144 Wheat and corn starches were phosphorylated in a semidry state at P from phospholipids), and its pasting properties showed optimum 1300C with 5% (based on dry starch) sodium tripolyphosphate (STPP) thickening power with shear stability when cooked at 950C. The best and/or 2% sodium trimetaphosphate (STMP). All phosphorylation corn starch phosphate, judging from its pa...
