With electron microscopy the investigation on isothermal martensite transformation in an Fe20.5Ni-4.8Mn alloy has been carried out to clarify the effect of austenite state on the transformation, by applying pre-deformation to austenite before isothermal holding. Under the condition without pre-deformation, the isothermal martensite products are lath martensite with {111}fhabit planes. Dislocations in austenite seem to contribute to nucleation of martensite, and in this nascent Stage austenite substructure has no obvious effect on martensite growth. The consequent thickening of martensite laths is apparently influenced by local austenite states, resulting in the changes in orientation, morphology as well as substructure of martensite lath. The kinetics of isothermal martensite transformation is controlled by intedece dislocation determined nucleation of martensite in primary stage, but to a larger extent, by the austenite accommodation for the shape strain of martensite in the thickening Stage

Stress corrosion cracking (SCC) is one of the major reasons to reduce the reliability of aged reactor components. Toshiba has been developing underwater laser cladding and underwater laser seal welding techniques onto surface with crack as maintenance and repair technologies. In the previous report, it was confirmed that underwater seal welding

Background: Molecular targeted agents, such as bevacizumab and cetuximab, have been shown to improve the overall survival of metastatic colorectal cancer (mCRC) patients. However, we still do not know the best sequence in which to use the molecular targeted agents for mCRC, especially in K-ras wild-type cases. Methods: From July 2006 to November 2010, 63 chemotherapy-naive patients who were diagnosed with mCRC and received an oxaliplatin-based regimen as the first line, did not respond to a bevacizumab-containing regimen used as the first or second line, and received cetuximab or continued bevacizumab, were eligible for this analysis. Thirty-two patients received cetuximab as the third or fourth line chemotherapy due to the K-ras wild-type (Group A). Also, thirty-one patients continued a bevacizumab-containing regimen in spite of disease progression (Group B). Results: The difference in the rate of serious adverse events was not significant between the two groups, but the rate of overall adverse events tended to be higher in Group A than in Group B. The median overall survival (MST) was significantly higher in Group A than Group B (30.8 months and 23.13 months (95%CI: 15.80 - 30.47), respectively) (P = 0.031). Group A patients were all K-ras wild-type, and 21 of Group B were K-ras mutant type. Compared with Group B patients with the K-ras mutant type, MST of Group A patients was significantly longer (30.8 months and 25.73 months, respectively) (P = 0.025). Conclusion: Using cetuximab after progression with bevacizumab might be an effective sequence to improve the overall survival of K-ras wild-type mCRC patients. However, we need further prospective studies to identify the best sequence of chemotherapy for mCRC patients.

The purpose of this study is to evaluate the effect of a low consumption protein-energy supplement that incorporates 15% of coconut pulp expeller in bovine animals. These pasture fattening cattle were checked on daily weight gain, supplement consumption and efficiency of pasture use. This study was carried out in a livestock establishment in the Department of Concepción, Paraguay. A total of 108 animals were selected;castrated male bovines, 342 ± 30.2 of body weight (BW), age average 28 months, Nelore breed distributed in 2 treatments (T1 and T2): T1 = 42 animals;control group (pasture + conventional mineral salt) and T2 = 66 animals;treatment group with a protein-energy supplement (pasture + protein-energy supplement with minerals). In both treatments, the animals grazed on pasture of Brachiaria brizantha cv. Marandú and Panincum maximaun cv. Tanzania used a system of pasture rotation of 1 - 3 days of occupation and 35 - 40 days of rest. The average daily weight gain (DG) was 0.82 and 0.83 kg/day (p > 0.05), the supplement consumption was 0.1 and 0.28 kg/day per animal and the % disappearance of the biomass of 18 and 23% for T1 and T2, respectively. In conclusion, there was no evident effect on DG of protein-energy

A narrow open channel resonant phenomenon, newly found by the authors in corresponding numerical calculations , was proved to exist based on the method of matching asymptotic expansions for three different channel configurations. It is shown that the resonant wave numbe rk emerges around kL=nπ, n=1,2,3,…∞ with a corresponding frequency s hift, where L is the length of the channel. It is also clear that the resona nce in a narrow open channel is an essential property of a channel as long as it is uniformly narrow.
