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. Morpho-agronomic characterization and genetic divergence among pepper accessions
ABSTRACT The germplasm characterization and the analysis of genetic divergence are fundamental requirements to determine the genetic diversity available and peppers have considerable variability not most explored and quantified. Thus, the aim of this study was to characterize morphological and agronomically pepper accessions and their genetic divergence. The

8. Innovative gas chromatographic determination of formaldehyde by miniaturized extraction and on-fiber derivatization, via SPME and SPME Arrow
Formaldehyde (FA) is a carbonyl compound, ubiquitous in the environment and among the most widespread pollutants: it has exhibited toxic properties and is classified as a human carcinogen. FA is released from several sources, both temporary (e.g., combustion processes) and permanent (e.g., building products). This work proposes an innovative fully-automated

9. Validation of blood components transport through a pneumatic tube system
ABSTRACT Introduction: Urgent blood component transfusions may be life-saving for patients in hemorrhagic shock. Measures to reduce the time taken to provide these transfusions, such as uncrossmatched transfusion or abbreviated testing, are available. However, transport time is still an additional delay and the use of a pneumatic tube system (PTS) may be an

11. Thermal characterization of soil-cement bricks using mining tailings
Abstract Soil-cement bricks are earth construction materials that have been gaining prominence due to their environmental advantages. The Brazilian Technical Standard NBR 8491 establishes physical and mechanical procedures to characterize these bricks. However, the thermal characterization is an important assessment, since it is related to the building’s t
