The reduced natural durability and low energy density of eucalyptus wood hampers its use to generate energy. Torrefaction or pre-carbonization, treatment in low oxygenation with temperatures between 200 ℃ and 300℃, accumulates carbon and lignin, decreases hygroscopicity, increases energy efficiency and reduces the wood attractiveness to xylophagous organisms, such as termites. Therefore, this work had as its main aim to study the influence of the roasting temperature on the endurance of the Eucalyptus urophylla wood in natura as well as roasted, both exposed to the attack of dry-wood termites. To the execution of this study, in natura wood chips and torrefied chips (torrefied for 20 min at the following temperatures: 180, 220 and 260 ℃) were submitted to the dry-wood termite resistance test. In this experiment, termites of the Cryptotermes brevis species were used. After 45 d of exposure, it was possible to observe that the torrefied treatment presented a greater resistance that consequently increased the endurance when exposed to the termite’s attack, observing that the control sample, loss five times more than mass than the chips torrefied at 260℃. Besides, in the treatment with in natura chips, was observed less mortality of the termites and greater visual damage, confirming the lower durability of such material compared to torrefied chips.

目的统计参数图（SPM）通过解剖模板模型进行空间标准化这一初始步骤后,可提供来自;F-FDG PET脑显像的有用的体素-体素分析。该研究旨在评估颞叶癫患者术前检查设置中的块匹配（BM）标准化方法,该方法中多数变换通过小块进行计算,其原则为最小化伪影和克服额外的图像滤波。方法采用BM和常规SPM标准化方法及来自年龄校正对照的PET图像,回顾性分析具有良好表征的31例颞叶癫患者的脑FDG PET图像,其中22例具有常见的内侧颞叶癫。对集群卷积进行不同的阈值P值校正（0.01、0.005和0.001）。结果对于颞叶和颞叶外低代谢灶的整体卷积,BM所提供的数值与SPM的数值几乎相等,且两者检测受累颞叶的灵敏度相似,SPM和BM分别达87%和94%,阈值P值为0.01。但BM对于颞叶内侧病变的精确定位能力高于SPM,其灵敏度为78%,SPM为45%（P<0.05）。结论与传统的SPM方法相比,BM标准化法对于颞叶癫患者的FDGPET图像进行基于体素的量化分析相对更好。但仍需对不同人群做进一步研究,以确定在这种情况下BM确实能准确替代SPM。

在疫情期间,随着抵押贷款利率降至历史低点,全国住宅价值和房地产活动飙升。在典型的"用户成本"房价模型中,尤其在低利率水平下,房屋价值对利率非常敏感。该模型可以在观察到利率下降时解释房价的上涨。但从经验来看,房屋价值对利率的敏感程度远不及用户成本模型预测的那样。
