1. Analysis of Quenching Parameters in AISI 4340 Steel by Using Design of Experiments
This paper aims to investigate the effects of quenching parameters (temperature and time of austenitizing and cooling rate) on the microstructure, hardness and distortion of AISI 4340 steel by Design of Experiments (DoE). The factorial design was used to determine the influence of the factors on the response variable. After quench samples were characterized

2. Estudo das distorções em aços AISI 5160 e AISI 6150 com variação da temperatura e da agitação do meio de resfriamento / Distortion studies in AISI 5160 and AISI 6150 steel under variation of bath quenching temperature and agitation
A distorção em tratamento térmico é a maior causa dos problemas na indústria. Existem vários parâmetros que compõem esse fenômeno. Com o avanço da tecnologia, a medição de algumas variáveis intrínsecas ao fenômeno da distorção se tornou possível, auxiliando no melhor conhecimento do processo o que resulta na diminuição do retrabalho e suc

3. Open charm tomography of cold and hot nuclear matter
We identify the nuclear effects that modify the cross sections for open heavy flavor production in proton-nucleus and nucleus-nucleus collisions. In p+A reactions, we calculate and resum the coherent nuclear-enhanced power corrections from the final-state parton scattering in the medium. We find that single and double inclusive open charm production can be s

4. Change in State of Spin Labels Bound to Sarcoplasmic Reticulum with Change in Enzymic State, as Deduced from Ascorbate-Quenching Studies
The ATPase (EC 3.6.1.3) of sarcoplasmic reticulum vesicles was reacted to various extents with thiol-directed spin labels. By suspension of the preparation in appropriate solutions, the enzyme could be placed and held in certain intermediate states of the ATPase cycle, or it could be set into steady-state catalysis. Ascorbate added to the system destroyed th
