1. Application of Response Surface Modeling and Chemometrics Methods for the Determination of Ofloxacin in Human Urine Using Dispersive Liquid-Liquid Microextraction Combined with Spectrofluorimetry
Dispersive liquid-liquid microextraction (DLLME) and spectrofluorimetry, coupled with chemometrics methods, are proposed in this work for the pre-concentration and determination of ofloxacin concentration in spiked human urine. Chloroform and acetonitrile were selected as the extraction and dispersive solvents by the one-variable-at-a-time process. The Box-B

2. Estudo laboratorial dos danos causados pelo broqueamento e retificaÃÃo em corpos-de-prova testemunhos
It is normal in engineer practice to use core testing to determine the inplace compressive strength of concrete in a structure. Generally, cores are obtained to: Asses whether suspect concrete in a new structure complies with strength-based acceptance criteria; or determine in-place concrete strengths in an existing structure for the evaluation of structural

3. Micropipette suction for measuring piconewton forces of adhesion and tether formation from neutrophil membranes.
A new method for measuring piconewton-scale forces that employs micropipette suction is presented here. Spherical cells or beads are used directly as force transducers, and forces as small as 10-20 pN can be imposed. When the transducer is stationary in the pipette, the force is simply the product of the suction pressure and the cross-sectional area of the p
