1. Influence of grinding on the pozzolanic activity of granite residue
Abstract This study explores the potential of the granite residue to be applied as a supplementary cementitious material. Furthermore, the efficiency of grinding methods in the improvement of the residue reactivity was also evaluated. The granite residue was collected in a facility located in Brazil and used as a Portland cement replacement with a substituti

2. Fracture Toughness and Charpy CVN Data for A36 Steel with Wet Welding
Abstract This study presents KIC data obtained from KIC-CVN correlations from Charpy CVN values. For this study, T-welded connections were manufactured from ASTM A36 and E6013 electrodes in dry conditions. Then, a rectangular grinding at the weld toe was carried out and filled with wet welding. Charpy specimens were extracted to obtain CVN values. An exhaust

3. Improvement of physicochemical parameters of acyclovir using cocrystallization approach
ABSTRACT Acyclovir is an antiviral drug having potent activity against the virus of herpes family and varicella zoster. Unfortunately, drug suffers very poor oral bioavailability (15-30%). The main objective of present study was to develop acyclovir cocrystals with improved solubility which may result in improvement of bioavailability. Hansen solubility appr

4. Avaliação nutricional de derivados da moagem úmida do milho para frangos de corte industrial
Several studies have demonstrated the influence of bird age on the digestive and absorptive processes, resulting in different recommendations on diet elaboration. This study observed the age effect on apparent (AMEn) and true metabolizable energy nitrogen corrected (TMEn) values and dry matter (DMMC) and crude energy metabolizability coefficient (CEMC) of wh

5. Fosfatos de calcio aditivados com fosfato de niobio (V): analise por difração de raios X e de biocompatibilidade com eritrocitos humanos
Hydroxyapatite (HAP) samples were prepared by the chemical precipitation method and were added niobium phosphate (NbOPO4) through wet grinding, up to 1%, 5% and 10% in mass of NbOPO4. The samples were thermally treated under 1100C and 1300C. Analysis through X-ray powder diffractometry using the Rietveld method identified the phases in each sample. In vitro

6. Maintenance of stellite and tungsten carbide saw tips: respiratory health and exposure-response evaluations.
OBJECTIVE--To study exposure to cobalt and chromium in saw maintenance rooms and test respiratory health among saw filers at lumber mills. Hard-metal lung disease is associated with cobalt in the manufacture of tungsten carbide tools; recently it has also been reported among tool maintenance workers. Lumber mills often use saws tipped with tungsten carbide o
