摘要： 人们在选择新的计算机时,常常会忽视触控板。很少有客户会仅仅根据触控板的品质来决定购买计算机,然而有些客户现在开始注意到这些不可或缺的硬件了(如图1)。一些技术产品评论都称赞苹果更大尺寸的触控板;微软在2017年通过更新精确触控板驱动程序改善了PC用户体验;联想的Yoga 9i笔记本电脑则探索了全新的触控板外形设计。

关键词： 选煤厂   机电设备   管理   维护  

摘要： 随着我国综合国力的不断提升,我国矿业的发展水平也逐渐提高,机电设备管理工作是选煤厂生产运营中的一项基础性工作。对机电设备实施有效的管理,可以确保其正常运行,有利于保障选煤厂的生产效率。对机电设备进行定期维护保养,可以延长设备的使用寿命,有利于降低选煤厂的生产成本。洗煤厂生产运营中,机电设备面临着相对恶劣的洗煤工作环境,导致机电设备管理与维护的难度较大。若想实现洗煤厂的高效生产、安全生产,必须高度重视机电设备管理及维护工作。

摘要： Purpose Professional bus drivers risk developing musculoskeletal pain (MSP) and disability due to their working condition. The current study investigates the prevalence rate of MSP and disability among professional bus drivers. Methods A cross-sectional study was conducted among 83 professional bus drivers. The prevalence rate of MSP was evaluated using a standardized Nordic musculoskeletal questionnaire. The disabilities due to the MSP were evaluated using neck disability index (NDI), Oswestry disability index (ODI) and shoulder pain and disability index (SPADI) tools. Prevalence of MSP was presented with 95% of confidence interval (CI) at an alpha level of 0.05. The 12 months and 7 days prevalence of MSP were tabulated for analysing the trend of MSP between the upper and lower body regions. Results The drivers had a mean driving experience of 10.07 +/- 7.26 years. The mean driving hours/week were 50.25 +/- 12.82 h. Neck and back were the most affected regions with a prevalence rate of 81.9% (N = 68) and 80.7% (N = 67) at 12 months. Back region recorded the highest 7 days prevalence rate for MSP with 53% (N = 44). Approximately one fourth of the bus drivers population (23.9%, N = 16) had moderate disability in back region. More than half with MSP in the neck region presented mild disability (54.4%, N = 37). Conclusion The bus drivers reported a high prevalence rate of MSP in the neck, back and shoulder regions with mild to moderate disabilities. Appropriate health care and rehabilitation programs are necessary for the prevention and management of MSP among the bus drivers.

摘要： Human-induced environmental changes have increased rapidly during the Holocene and have reached alarming levels today. Consequently, it is crucial to better understand the impact of humans and climate on the faunas and floras through time. Understanding the direct and underlying effect of past human activity not only contributes to improving our knowledge of human history but also provides insights for the future. We here investigate the effect of the human-induced environmental changes that took place during the modern era (14-19th century AD) on the mandible of a small mammal, Suncus etruscus, in Corsica. We detected rapid morphological changes in mandible shape over the relatively short period of time included in our study, suggesting a strong human impact on the island. The morphological changes observed had functional consequences as they are related to changes in the mechanical potential of the principal masticatory muscle, the temporalis that, in turn, reflects shifts in the animal's diet over time. These results highlight the effect that the 600-year human agricultural activity shifts had on the island and its fauna. The integration of the body and the ramus of the mandible appears to be related to the mechanical potential of the temporalis muscle but does not constitute an indicator of human-induced environmental change. Whether these morphological changes are the result of natural selection (genetic processes) or of phenotypic plasticity (epigenetic processes) remains to be elucidated.

摘要： This work presents a detailed investigation of twin inception to identify site of twinning, variant type selected, and the strain to nucleate it within a full 3D reconstructed microstructure obtained using 3D-EBSD. Microstructurally-faithful 3D crystal plasticity analysis provides quantitative insight to show that stored energy density is a key factor (rather than stress or other criteria) which identifies the experimentally observed twin nucleation site (which supersedes twin inception), and the strain necessary to drive nucleation. 3D (as opposed to 2D surface) analysis has been shown to be essential. The critical energy density for twin nucleation was found to be -0.015 Jm-2 in Mg alloy AZ31. Further, at the predicted nucleation site, the experimentally observed twin variant is shown to be driven by the local twin resolved shear stress.
