| 1 | Quantitative Study on Nonmetallic Inclusion Particles in Steels by Automatic Image Analysis With Extreme Values Method显示文摘The presence of nonmetallic inclusion particles which appear during steelmaking process is harmful to the properties of steels,which is mainly as a function of some aspects such as size,volume fraction,shape,and distribution of these particles.The automatic image analysis technique is one of the most important tools for the quantitative determination of these parameters.The classical Student approach and the Extreme Values Method(EVM) were used for the inclusion size and shape determination and the evaluation of distance between the inclusion particles.The results thus obtained indicated that there were significant differences in the characteristics of the inclusion particles in the analyzed products.Both methods achieved results with some differences,indicating that EVM could be used as a faster and more reliable statistical methodology. | Cássio Barbosa José Brant de Campos Jneo Lopes do Nascimento Iêda Maria Vieira Caminha | 2009 | Journal of Iron and Steel Research(International)2009，16，4： | 7 |
| 2 | Impact of laparoscopic surgery training laboratory on surgeon's performance显示文摘Minimally invasive surgery has been replacing the open standard technique in several procedures. Similar or even better postoperative outcomes have been described in laparoscopic or robot-assisted procedures when compared to open surgery. Moreover, minimally invasive surgery has been providing less postoperative pain, shorter hospitalization, and thus a faster return to daily activities. However, the learning curve required to obtain laparoscopic expertise has been a barrier in laparoscopic spreading. Laparoscopic surgery training laboratory has been developed to aid surgeons to overcome the challenging learning curve. It may include tutorials, inanimate model skills training(box models and virtual reality simulators), animal laboratory, and operating room observation. Several different laparoscopic courses are available with specific characteristics and goals. Herein, we aim to describe the activities performed in a dry and animal-model training laboratory and to evaluate the impact of different kinds of laparoscopic surgery training courses on surgeon's performance. Several tasks are performed in dry and animal laboratory to reproduce a real surgery. A short period of training can improve laparoscopic surgical skills, although most of times it is not enough to confer laparoscopic expertise for participants. Nevertheless, this short period of training is able to increase the laparoscopic practice of surgeons in their communities. Full laparoscopic training in medical residence or fellowship programs is the best way of stimulating laparoscopic dissemination. | Fabio C M Torricelli Joao Arthur B A Barbosa Giovanni S Marchini | 2016 | World Journal of Gastrointestinal Surgery2016，8，11： | 6 |
| 3 | Structural phase relations in perovskite-structured BiFeO_(3)-based multiferroic compounds显示文摘In this review,the state of the art in understanding the structural phase relations in perovskite-structured BiFeO_(3)-based polycrystalline solid solutions is presented and discussed.Issues about the close relation between the structural phase and overall physical properties of the reviewed systems are pointed out and discussed.It is shown that,by adjusting the structural symmetric arrangement,the ferroelectric and magnetic properties of BiFeO_(3)-based polycrystalline solid solutions can be tuned to find specific multifunctional applications.However,an intrinsic mechanism linking structural arrangement and physical properties cannot be identified,revealing that this subject still deserves further discussion and investigation. | Valdirlei Fernandes FREITAS Gustavo Sanguino DIAS Otávio Algusto PROTZEK Diogo Zampieri MONTANHER Igor Barbosa CATELLANI Daniel Matos SILVA Luiz Fernando CÓTICA Ivair Aparecido dos SANTOS | 2013 | Journal of Advanced Ceramics2013，2，2： | 2 |
| 4 | 金龟子绿僵菌分生孢子暴露在B段紫外光下毒力的降低显示文摘The UV-A and UV-B wavelengths of solar radiation may seriously reduce viability of Metarhizium anisopliae conidia,a fungus used extensively in Brazil for insect pest control.The conidial tolerances to UV-A and UV-B radiation were studied for one isolate(IBCB 425) commercially available product produced on rice grains.Aqueous or oil emulsion conidial suspensions were irradiated for 0(control),2,or 3 h using the solar simulator filtered with diacetate filter to remove UV-C radiation which afforded 652 mW·m-2 in the spectral range of 280~370 nm.The UV tolerance was based on conidial germination(viability) and virulence to Diatraea saccharalis larvae.Conidia formulated with oil emulsion had higher survival after 3 h of UV exposure,but the virulence of the conidia previously exposed to 2 h of UV radiation were similar when oil formulated or not.The mortality of D.saccharalis caterpillars exposed to non-UV-irradiated conidia was greater than that of larvae exposed to irradiated conidia,and the LT50 values were lower for the non-irradiated suspensions than for those irradiated.This apparent reduction in virulence was directly related reduction in viability or delay of germination of UV-irradiated conidia. | Edimara A Francisco Drauzio E N Rangel Newton La Scala Jr José C Barbosa Antnia do C B Correia | 2008 | 安徽农业大学学报2008，35，2： | 2 |
