Heating pre-treatment of copper ores and its effects on the bond work index
(MDPI, 2022)
Comminution is the stage with the largest energy consumption in the mining process. Therefore, several pre-treatments have been proposed to reduce the energy requirements of this stage. This work analyzed the effect of a ...
Influence of pre-heat treatment and different light-curing units on Vickers hardness of a microhybrid composite resin
(2009-06-01)
The aim of this study was to evaluate the hardness of a dental composite resin submitted to temperature changes before photo-activation with two light-curing unite (LCUs). Five samples (4 mm in diameter and 2 mm in thickness) ...

Mating success at high temperature in highland- and lowland-derived populations as well as in heat knock-down selected Drosophila buzzatii
(Wiley Blackwell Publishing, Inc, 2015-03)
Thermal-stress selection can affect multiple fitness components including mating success. Reproductive success is one of the most inclusive measures of overall fitness, and mating success is a major component of reproduction. ...
Influence of milk pre-treatment on production of FFA and volatile compounds in hard cheeses: heat treatment and mechanical agitation.
(American Dairy Science Association, 2010-10)
This work was aimed at identifying technological steps that can increase fat hydrolysis and volatile compounds production in hard cheeses, as these biochemical events have been related with improved piquant taste and ...
Acceptability of beetroot pre-processed under different cooking methods
(Univ Federal Mato Grosso, 2016-07-01)
This study aimed to evaluate the acceptability of beet subjected to four heat treatments (steam cooking, cooking in a pressure cooker, cooking in the oven and immersion in water) and three different pre-preparation methods ...
Heat-stress survival in the pre-adult stage of the life cycle in an intercontinental set of recombinant inbred lines of Drosophila melanogaster
(Company of Biologists, 2013-07)
In insects, pre-adult stages of the life cycle are exposed to variation in temperature that may differ from that in adults. However, the genetic basis for adaptation to environmental temperature could be similar between ...
Hepatic concentration of heat shock protein 70 kD (Hsp70) in broilers subjected to different thermal treatments
(Carfax Publishing, 1999-05-01)
1. The relationship between repeated thermal treatments and hepatic synthesis of Hsp 70 was studied in broiler chickens.2. Sixty broilers were submitted to 5 different treatments (12 birds each) from day 1 to day 42. Four ...

Influência do pré-aquecimento na perda de massa de revestimentos duros aplicados pelo processo de soldagem com arame tubular
(Universidade Tecnológica Federal do ParanáCuritibaBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2012-10-23)
Hardfacing applications are largely used on parts that suffer from abrasions wear. Those materials have a high wear resistance characteristic that guarantee lower reposition and maintenance costs. They also assure a longer ...
