两例秃鹫（Aegypius monachus）痛风病自然病例的诊断和病理学观察
野生动物学报, 2020 本研究以尸体剖检和组织病理学方法诊断了2例秃鹫（Aegypius monachus）痛风病并进行系统的病理学观察。结果表明2只秃鹫均表现为严重的痛风性关节炎和内脏痛风。尸体剖检显示双侧跗关节和趾关节明显肿大，关节腔内积有大量灰白色黏稠的尿酸盐结晶。除脑和脊髓外，全身组织器官表面和切面散在或弥漫性分布大小不等的点状、细针状、条索状和斑状的痛风结节。组织病理学观察显示全身各组织器官内均散在或弥漫性分布大小不等的圆形、椭圆形红染的Ⅰ型和Ⅱ型痛风结节。Ⅰ型痛风结节呈向日葵样或车轮状 ...

Investigation of Irradiation Behavior and Corrosion Properties of the N36 Zr Alloy Developed by China [PDF]
, 2016 本文对中国核动力研究设计院自主研发的两种制备工艺的N36锆合金进行了微观组织与微观化学分析和表征。采用400千伏离子注入机对锆合金进行辐照，分析辐照后的微观结构，以研究其辐照行为与规律。采用高温高压反应釜对原始态锆合金和受辐照的锆合金进行了腐蚀，分析了不同实验条件下锆合金表面氧化层、氧化膜/金属界面和金属基体的微观结构演变规律与特点。 增加冷轧次数与退火过程会导致锆合金的晶粒尺寸变大和不均匀化，平均尺寸从3.9μm长大到6.0μm；且析出相的尺寸变大、弥散程度降低，平均尺寸从74.6nm长大至89 ...

Conservation Biology, EarlyView.Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

Zhongguo shiyan zhenduanxue, 2023 MRI对软组织结构具有非常高的分辨率，不受屈光介质影响，在临床诊断眼部病变中，MRI可以起到非常重要的作用。但是因为眼部含有眼球及其附属的许多精细结构，解剖结构错综复杂，所以在常规使用头线圈进行眼球MRI检查存在一定不足[1]。常规3.0TMR眼部扫描采用8通道相控阵线圈或16通道相控阵线圈，虽然该线圈具有良好的均匀性，但是扫描范围、扫描视野相对较大。由于眼部组织结构细小复杂，建议使用眼部成像的专用针对性线圈，从而满足高分辨、

International Journal of Applied Linguistics, EarlyView.ABSTRACT This paper examines the features of metadiscourse across different teacher moves in university linguistics classroom discourse and the teaching strategies reflected in its use. The results reveal that teachers employ diverse metadiscourse during classroom interactions to support student reasoning.

野生动物学报, 1991 采用石蜡切片,HE染色法,对四只成年东方白鹳的消化器官进行了组织学研究。发现一些明显特点。东方白鹳的十二指肠极为发达,长约80—100厘米。肠绒毛较长,且无分支现象。小肠其它各段和大肠较短,盲肠一对,但很不发达.仅长约0.8—1.1厘米。盲肠腔窄小,管壁厚,壁内充满了淋巴组织,肠腺很少。肝、胰脏组织结构基本与家禽的结构相似。

Design and Implementation of Hospital Outpatient Information Management System Based on ASP.NET [PDF]
, 2015 目前，我国医疗资源分配不均，优质医疗资源过分集中在一线中心城市，导致优质医疗资源供不应求，中心大中型医院人满为患，一定程度上激化了医患、诊疗之间的矛盾。我们希望借助信息技术带来的巨大推动力，通过建设一套“医院门诊信息系统”，将医院的工作流程信息化，提高医疗信息的透明度，从而能够减轻患者就诊的负担和医生工作的压力。 本文中分析了国内公立医院的患者就诊流程。从实际医患互动的角度出发，充分融汇以人为本的指导思想，将医患双方放在系统的核心位置，设计用户在诊疗过程中的体验。 为实现上述功能，针对医院的门诊系统 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT With the internationalisation of higher education, English medium instruction (EMI) has become increasingly common in non‐English‐speaking contexts. However, research highlights a range of challenges in EMI implementation, including insufficient collaboration between content and language teachers, limited professional development opportunities
