1. Budbreak of pecan cultivars subject to artificial chill
ABSTRACT Chill is a limiting factor in commercial production of temperate fruit due to their dormancy mechanism. Thus, knowledge of chill requirements of cultivars is important to reach successful production. This study aimed at evaluating responses given by different pecan cultivars subject to artificial chill. Pecan branches were collected from twelve 9-ye

6. Thermal Infrared Enthalpimetry Method for the Determination of Hypochlorite in Bleaching Solutions
Thermal infrared enthalpimetry (TIE) was used for hypochlorite determination in commercial hypochlorite-based bleaching solutions. Experimental parameters were evaluated for the reaction with a hydrogen peroxide solution. The most relevant conditions were 5% H2O2 (m/m) solution, stirring speed of 250 rpm, dispensing rate of 0.57 mL s-1, and 10 s after reacti

7. Effects of plaster to water ratio on physical and mechanical properties of ceramic pieces produced by the slip casting process
Abstract In the slip casting process, the relationship between the amount of plaster and water used in the production of molds influences the production of ceramic materials, because the higher the water content in the mixture, the lower the mechanical strength of the mold and higher the water absorption rate. In order to evaluate the influence of the variat

8. EFFECT OF MERCURY EXPOSURE ON U1-70 KDA PROTEIN EXPRESSION IN EMBRYOS OF BLACK BEAN (Phaseolus vulgaris L.)
Exposure to heavy metals has been documented to induce changes in the expression of plant proteins. Phaseolus vulgaris L., represents a great source of nutrition for millions of people, and is the second most important legume crop. The present study aimed to investigate the effects of Hg stress on germination rate and identify the gene expression profiling o

10. Sintering mechanisms of partially stabilized zirconia (TZ3Y) with ZnO and Co3O4 as sintering additives
Abstract In this work, the sintering mechanisms of 3 mol% yttria-stabilized zirconia (TZ3Y) and TZ3Y containing 0.3 wt% of ZnO or Co3O4 were analyzed by determining the apparent activation energy of sintering from dilatometry data and observing the evolution of microstructure. Dilatometry test was performed at a heating rate ranging from 5 to 20 °C/min from
