Veterinary Dermatology, Volume 35, Issue 5, Page 479-491, October 2024.Background – Lop‐eared rabbits may be predisposed to otitis externa (OE) as a consequence of their ear conformation. Although otoscopy, otic cytological evaluation, and culture are valuable tools in dogs and cats, published data on rabbits remain lacking. Hypothesis/Objectives – This study aimed to assess the utility of otoscopy and cytological results

Study on long-term behavior of steel-reinforced concrete columns under axial sustained compression [PDF]
, 2014 随着国民经济的快速发展，钢骨混凝土结构的应用越加广泛，人们对钢骨混凝土结构的了解也越来越全面和深入，目前，对于钢骨混凝土柱的研究主要是集中在其极限承载力、粘结强度与抗震性能等方面，对于长期荷载作用下混凝土的收缩、徐变等力学特性的研究还较少。而且目前对钢-混凝土组合结构的长期荷载作用的性能的试验与理论研究主要还是针对钢管混凝土。然而，由于钢管混凝土中的混凝土处于钢管内，而钢骨混凝土中的混凝土则是外露于环境中，二者在长期荷载作用下的收缩和徐变特性必然会不同 ...

Influence of resisted horizontal vibratility and stability ability to the reinforced concrete column by pre-stressing force [PDF]
, 2009 针对普通钢筋混凝土柱抵抗水平性能较弱的特点，考虑在柱中布置一定数量的预应力筋并施加有效预应力来改善这一状况。本文对钢筋混凝土柱考虑预应力影响下的抗水平性能、稳定效应以及由此而构建的整体预应力混凝土框架结构的抗水平性能进行分析研究，主要工作及结论如下： （1）基于截面应变协调分析方法，经过分析推导得出钢筋混凝土柱考虑预应力影响下的水平荷载－位移求解公式，为分析钢筋混凝土柱抗水平性能提供了一定的理论依据。 （2）对钢筋混凝土柱考虑预应力影响下抗水平性能进行全过程非线性分析，研究了构件从开裂 ...

Jianzhu Gangjiegou Jinzhan, 2017 针对单肢C形和U形截面及由其拼合而成的双肢和四肢截面冷弯薄壁型钢柱轴压承载力,进行了66根(共6种截面,5种长度)两端铰接的多肢拼合截面冷弯薄壁型钢柱轴压试验,研究了长细比、肢数及拼合形式对冷弯薄壁型钢多肢拼合柱轴压受力性能的影响。试验结果表明:长细比小于70的开口截面易发生畸变屈曲,闭口截面则发生局部屈曲;长细比大于70的试件则以整体屈曲破坏为主;随着试件的长度增加,其轴压承载力逐渐降低。相对于单肢截面,相同高度的拼合截面长细比减小,试件破坏形式随着长细比减小而从整体屈曲控制变为畸变屈曲和局部屈曲控制,
