Introduction. Turcot’s syndrome is characterized clinically by the concurrence of a primary brain tumor and a familial adenomatous polyposis or a hereditary nonpolyposis colorectal cancer. Observation. We report a case of a 45-year-old woman who underwent in 1995 neuro-oncological treatment for an anaplastic astrocytoma (grade III according to the World Health Organization classification). Treatment included complete surgery, radiotherapy, a first-line nitrosourea-based chemotherapy regimen and a second-line platinium salt-based regimen. It was then noted that the patient’s brother had colorectal cancer. A genetic study detected a germ-line mutation on the hMSH2 gene specific of HNPcc syndrome (Human Non Polyposis colorectal cancer). colonoscopy was normal. Eight years after the diagnosis, the patient developed a gliomatosis cerebri and died. conclusion. Relevant personal and familial history can provide the clue to the diagnosis of Turcot’s syndrome. Molecular diagnosis may contribute to appropriate care of affected patients.

Introduction. The imaging presentation of some forms of multiple sclerosis may be misleading. In patients with a history of recent infection or vaccination, e specially for adolescents or young adults, the differential diagnosis with acute disseminated encephalomyelitis can be difficult. case report. We report an unus ual clinical and radiological presentation of multiple sclerosis,mimicking acute disseminated encephalomyelitis. We discuss clinical and radiological differenti al diagnosis, and the outcome after immunosuppressive treatment. conclusion. Dis tinguishing between acute disseminated ncephalomyelitis and the first relapse of multiple sclerosis can be diffficult. Brain imaging is a precious tool for diff erentiating between the two diseases.

The precision of strip flatness depends on several factors; wear of rolls is one of the main variables that have influence on the surface quality of the strip. The wear of the roils represents a complex friction condition, sometimes the wear in the backup roll is not analyzed because the strip is not in contact with the backup roll; however, after several campaigns of rolling, the wear in the backup roll becomes dangerous because the pressure distribution is not uniform. Investigation of mechanism of the surface deterioration of the backup roll for the hot strip rolling is very important for the development of the automatic strip shape control system used in hot strip mills. A mathematical model is developed considering the Hertzian pressure distribution between two cylinders with parallel axes. It is used in real time for calculating the wear in the backup roll and in this manner take deci- sions for preventing finished product reworking or damage of equipments, which result in accidents caused by excessive wear in the backup rolls.

Ferroelectric single crystals Pb(Zn1/3Nb2/3)O3-PbTiO3 (PZN-PT) are promising full materials for non resonant or large bandwidth transducers due to the large values of their piezoelectric properties (d ij , k ij ) and their low mechanical quality factor (Q ij ). Many studies on oriented PZN-4.5PT single crystals were carried out but it is very difficult to find research findings on oriented Mn doped PZN-PT. Thus, investigations were made using XRD, Raman and EPR characterization for oriented PZN-4.5PT grown through the Flux method. Mn doping effect on structural, dielectric, mechanical and piezoelectric properties with two values of Mn percentage (1 and 2 mol%) are also reported in this paper. Through the XRD study, the lattice parameters of doped PZN-PT crystals are slightly increased compared to the undoped one but the Mn didn’t change its structure. The room temperature dielectric permittivity along direction is about 1572 and 1626 (respectively 1% and 2% Mn doped crystals) which are much lower than that of the undoped PZN-4.5PT (2553). The remnant polarization and coercive field of oriented doped crystal measured at 1 KHz are respectively 30 μc/cm2 and 4.30 kV/cm (PZN-4.5PT), 32 μc/cm2 and 6.10 kV/cm (PZN-4.5PT + 1% Mn) and 28 μc/cm2 and 7.30 kV/cm (for the 2% Mn doped crystal). The mechanical quality factor Qm changed from 139 to 441 respectively for the pure and 1% Mn doped single crystals at room temperature while it decreases slightly to 336 for the 2 mol% Mn doped.

The integration of ferroelectric materials as thin films has attracted considerable attention these last years thanks to their outstanding performances that allow considering new features for the realization of photovoltaic devices. Our study focuses on investigating structural, dielectric and ferroelectric properties of undoped and Mn doped PZN-4.5PT nanoparticles thin films on Silicon substrate. We fabricate very stable PZN-4.5PT nanoparticles thin films deposited on nanostructured silicon substrate with giant relative dielectric permittivity of 2.76 × 104 and 17.7 × 104 for respectively the undoped and Mn doped thin films. These values are very large compared to those found in single crystals and might be explained by the influence of the gel in which nanoparticles were dispersed. The SEM images show the crystallization of new hexagonal phases on the film surface probably coming from interaction between Si and the gel. The hysteresis loops permitted to determine the spontaneous polarization (Ps), remnant polarization (Pr) and coercive field Ec which are equal to 11.73 μc/cm2, 10.20 μc/cm2 and 20 V/cm, respectively for the undoped nanoparticles thin film and 22.22 μc/cm2, 19.32 μc/cm2 and 20 V/cm respectively for the Mn doped one. These values are high and correspond to the best ones found in literature compared to typical ferroelectric thin films.

采用反演法确定了马氏体不锈钢410的Johnson-cook本构方程材料参数.剪切实验采用的剪切速率为1～5000s-1,温度为20～1000℃.有限元模拟在Abaqus软件平台上进行.采用Johnson-cook模型,施加与实验相同的初始条件.通过Matlab非线性最小二乘法优化程序来调整有限元模型材料参数,找到合适值,使得模拟得到的力-位移曲线与实验得到曲线相吻合.结果表明,所得参数都能很好地代表不锈钢410在高温高变形速度下的流动特性,Johnson-cook模型不能描述材料破坏阶段的行为特征.
