目的:分析和比较市售的粗糙表面螺纹种植体与多孔圆柱种植体在兔模型愈合的不同时期骨沉积情况。此外,研究种植体表面形态对变形链球菌粘附的影响。材料与方法:采用粉末冶金技术的新方法,制备有致密核心和多孔表面的钛种植体.以增加种植体骨结合率(BIC)。15只兔中,植入60个种植体。在每只兔子右、左侧胫骨各植入两个实验组和对照组种植体。实验组采用敲击就位,对照组自螺纹就位。术后4周、8周和12周处死动物.脱钙处理,检测种植体骨接触率。此外.在16个种植体(8个实验组,8个对照组)表面培养变形链球菌,评价细菌粘附情况。分别进行方差分析和t检验。结果:两组组织学均显示种植体-骨界面紧密接触.无软组织介入。多孔圆柱型种植体BIC(72.41%±9.47%)高于粗糙螺旋种植体(61.23%±14.12%)(P=O.013).而变形链球菌粘附情况无显著差异(P=O.351)。愈合4周时,两组间差距更明显(P=O.029)。两组间BIC在整个实验周期无显著性差异(P=O.333),但BIC随时间延长而提高。结论:在本研究条件.结果显示:新型种植体增加了BIC,且未增加变形链球菌粘附。

CdCO3 thin films had grown onto glass by chemical bath deposition (CBD), the temperature of the bath (Td) was at 20 °C. The samples were thermal annealed temperature (TAT) in air atmosphere at normal pressure for 2 h at different temperatures in the range of 300-400 °C, in order to perform the crystalline phase transformation from CdCO3→CdO, Scanning Electron Microscopy (SEM), X-ray diffraction (XRD) and optical absorption (OA) measurements were carried out to characterized the films. The proportion of constitutive elements measured by means SEM for CdCO3 as-grown were: Cd = 12.8, C = 20.0, O = 67.2; TAT (CdCO3) = 400 °C: Cd = 49.8, O = 50.2, this results indicates good stoichiometric of samples. Patterns XRD show the layer with CdCO3 which has rhombohedral crystallineas-grown peaks at: 2θ = [23.4, 30.2, 36.4, 40.1, 43.8, 48.0, 49.5, 49.9, 58.2, 61.7, 62.9 and 65.5]. TAT (CdCO3) = 400 °C completely disappeared and only peaks of CdO are identified. All of the peaks in this pattern has pure cubic phase of CdO (2θ= [33.1, 38.2, 55.3, 59.9 and 69.3]). The average grain size (GS) which was calculated from the main XRD peak by CdCO3 reduce of 34.5 nm reaching 20 nm respectively was calculated by employing Scherer"s formula. The optical absorption spectra allowed to calculate the values of forbidden bandgap energy (Eg), and hence, the evolution of Eg in the thermally spectra also showed the complete microstructural transformation from as-grown for samples with higher annealing. The critical point of CdCO3→CdO is proposed to occur at TAT = 400 °C, CdCO3 as-grown: Eg = 3.87 eV, TAT (CdCO3) = 400 °C (CdO): Eg = 2.31 eV.

Pervasive and ubiquitous environments must handle the detection and management of users, devices and services, while guaranteeing the privacy of both the users and the environment itself. Current techniques for handling privacy found in the literature treating the subject in various ways, while concentrating on the device management, communication protocols, user profiles and environmental access. This paper examines a control model for privacy in pervasive environments from the perspective of the environment. A prototype was devised and tested to validate the generic model of privacy which was also used to compare taxonomic concepts in the literature. Moreover, the prototype was devised and tested to validate the generic model of privacy for control and manage various users, devices and environments and so on. The prototype was based on Percontrol (a system for pervasive user management), which was only intended to identify users using Wi-Fi, and now it is capable of managing temperature, luminosity and other preferences, measured by a WSN (wireless sensor network) embedded to Percontrol, and the data treatment is done by an ANN (artificial neural network). Results confirmed the viability of device detection with Wi-Fi, Bluetooth and RFID (radio frequency identification) for an increases slight of the latency in registering new devices on the system.

只要当过患者，或者当过陪患者看病的家属，每个人都会意识到医患关系的重要性。这种关系的核心是患者需要知道问题在哪里，要得到理解，要看到希望。尽管大家都知道希望是战胜任何疾病的基础，但是在给予希望的过程中，临床医生的作用却依赖于个人的经历和本能，并且被认为仅仅是一种独特的“医学技巧”。然而，实际上，希望是一个很实用的治疗手段，就像其他治疗手段一样，可以进行优化。

目的 :探讨胫骨关节面不同切除角度对胫骨假体稳定性的影响。方法 :15根Saw bones胫骨被分成 5组。胫骨关节面分别被切除为后倾 0°、3°、6°、9°和前倾 - 5° ,胫骨金属假体用骨水泥固定 ,然后先后插入标准和高倾聚乙烯假体 ,在屈膝 0°和 30°下进行载荷。结果 :每增加关节面后倾切除角度 ,标准聚乙烯假体的向前移动随之显著增加。在高倾的聚乙烯假体中 ,这种移动增加更为明显。而关节面前倾切除 (- 5°)则导致胫骨假体显著向后移动。在胫骨载荷方面 ,增加关节面后倾切除角度显著减少胫骨前面的压应力 ,而胫骨后面的压应力则显著增加。高倾假体也能显著增加后面压应力。结论 :实验的结果表明 0°或 30°胫骨关节面后倾切除角度提供胫骨假体最大的稳定性。

人类活动对全世界范围内生态系统服务和湿地功能的影响与日俱增。湿地生态系统具有重要的科学研究和社会价值，是生物多样性和水资源最丰富的地区。智利南部（大约39～41°s）目前，一些面积超过500hm^2的沿海和内地湿地受到临近城市工业废弃物排放、未利用土地转变为耕地和水抽提的威胁。这些湿地大多位于瓦蒂文（Valdivian）雨林的沿海地区，该雨林具有独特的生物特性，植物多样性高，且由于广泛的土地利用变化而发生片段化。湿地和瓦蒂文雨林的这些特征促进了智利政府和国际社会对该生态系统的保护.
