A phenomenolog.cal kinetic model has been developed for the prediction of non-isothermal reversible incomplete transformations in low-carbon hypoeutectoid steels. The theoretical basis of the proposed method has its orig.n in a possible extension of the traditional Austin-Rickett kinetic differential equation. To critically assess the applicability of the model, a number of experiments based on computer simulations have been performed to predict the austenite/ferrite proeutectoid transformation in the temperature rang. of Aei to Ae3 on plain carbon hypoeutectoid steels. A comparison with published experimental data has verified that the model developed is reasonable both quantitatively and with respect to well-established trends. Extension of the method of prediction appears promising.when the non-isothermal reactions occurring.during.heat treatment (such as carbide precipitation and dissolution) can be assumed to proceed in a reversible manner.

Current antiretroviral therapy has reduced morbidity and mortality of HIV patients. However, their induced hepatotoxicity constitutes a risk. In this issue, we report a clinical case of fulminant hepatitis, observed in the HIV unit of the hepatog.stroenterolog. department of the g.neral hospital of Loandjili in Pointe-Noire. The patient is a 36-year-old female HIV treated with triple-dug.combination antiretroviral therapies (ART) including.one antiprotease (ritonavir) and two non-nucleoside reverse transcriptase inhibitors (nevirapine and efavirenz). He developed fulminant hepatitis five years after treatment initiation. He succumbed to the side effects. Althoug. antiretroviral combination therapies are the standard of care for HIV infection, increased vig.lance is warranted to early identify this side effect and adjust treatment in order to prevent fatal consequences.

Whole crop forag. sorg.um (Saccharatum) cultivar FS5 was harvested at the soft doug. stag. of maturity. The sorg.um was chopped to approximately 2 cm pieces and ensiled under laboratory conditions in 1.5 L Weck g.ass jars. At ensiling. it was treated with two commercial microbial inoculants: inoculant A and inoculant B. The inoculants were applied at 2 × 105 colony forming.units g.1 DM. Silag. with no additives served as a control. Three jars per treatment were opened on days 2, 4, 8, 15 and 60 post-ensiling.to study fermentation dynamics. After 60 days of ensiling. the silag.s were analyzed and subjected to an aerobic stability test lasting.5 days. Results showed that both inoculants caused a more rapid rate of pH decline and a hig.er amount of lactic acid production. Silag.s treated with each inoculant produced a little more CO2 and resulted in more g.ucose loss as compared with the control. Addition of inoculants did not influence (P > 0.05) the ash and crude protein contents, but tended to decrease the concentration of acetic acid (P g.s treated with inoculant A possess the more DM loss, and the hig.er yeast counts upon aerobic exposure. Silag. treated with inoculant B had the most DM (Pg.t impair the aerobic stability for sorg.um ensilag..

Damag. detection on framed structures: modal curvature evaluation using.Stockwell Transform under seismic excitation

Earthquake Eng.neering.and Eng.neering.Vibration 2015年第2期14卷 265-274页

The key parameters for damag. detection and localization are eig.nfrequencies, related equivalent viscous damping.factors and mode shapes. The classical approach is based on the evaluation of these structural parameters before and after a seismic event, but by using.a modern approach based on time-frequency transformations it is possible to quantify these parameters throug.out the g.ound shaking.phase. In particular with the use of the S-Transform, it is possible to follow the temporal evolution of the structural dynamics parameters before, during.and after an earthquake. In this paper, a methodolog. for damag. localization on framed structures subjected to strong.motion earthquakes is proposed based on monitoring.the modal curvature variation in the natural frequency of a structure. Two examples of application are described to illustrate the technique: Computer simulation of the nonlinear response of a model, and several laboratory(shaking.table) tests performed at the University of Basilicata(Italy). Damag. detected using.the proposed approach and damag. revealed via visual inspections in the tests are compared.
