Use of a Cytobrush for Sampling the Ear Canal of Dogs With Otitis Externa

open access: yesVeterinary Dermatology, Volume 37, Issue 2, Page 227-235, April 2026.
Cytological examination of the ear canal is essential for evaluating dogs with otitis externa (OE). The conventional sampling method uses a swab. However, the cytobrush (gynaecological cervical brush), already used for cytological collection from other anatomical sites, has not been adequately investigated for this purpose in dogs with OE.

云南省几种传统水力机械的调查研究 [PDF]

open access: yes, 1994
中国历史上创造了多种多样的机械及有关工艺,这些机械和工艺在20世纪中叶以前,发挥了不可替代的巨大作用,其中不少机械和工艺延用至今,其原理、构造和制作工艺基本上没有变化,为便于与现代机械区别,我们称之为“传统机械”。 有关古代机械的记载,散见于多种古籍之中,并且,大多文字记述或图过于简略。为了便于与现代机械区别,我们称之为“传统机械”。有关古代机械的记载,散见于多种古籍之中,并且,大多文字记述或图过于简略。为了搞清古代机械的详细构造原理、制作工艺,一个可行的办法是调查研究现存的传统机械。1993年6月 ...

Investigating Drivers of Tiger Bone Glue Consumption in Vietnam 调查越南虎骨胶消费的驱动因素 Điều Tra Nguyên Nhân Dẫn Đến Tình Trạng Tiêu Thụ Cao Hổ Cốt Tại Việt Nam

open access: yesIntegrative Conservation, Volume 5, Issue 1, Page 115-124, March 2026.
We found the estimated use of tiger bone glue within the last 12 months to be 6.9%. We found a stated motivation of taking TBG to improve health, and by the suggestion of one's social group. We suggest reducing the acceptability of TBG as medicine and encouraging non‐animal‐based medicinal alternatives.

熏蒸条件下有机肥部分替代化肥对西瓜生长及养分利用的影响

open access: yesShuitu Baochi Xuebao, 2017
基于田间大棚试验,采用等量养分原则,分析生物有机肥、蚯蚓粪、鸡粪等不同有机肥部分替代化肥对西瓜生长、产量、品质以及养分利用的影响。结果表明,与单施化肥相比,有机肥部分替代化肥均不同程度提高了西瓜叶绿素含量、光合性能、产量及品质,其中以蚯蚓粪与化肥配施效果最佳,其光合性能显著高于单施化肥,产量提高了33.63%,可溶性糖、可溶性蛋白及维生素C含量分别增加了14.07%,14.47%和17.52%。有机肥部分替代化肥施肥处理的肥料利用率高于单施化肥,土壤养分元素依存率低于单施化肥 ...

Synthesis of Al-Fe pillared montmorillonite and its adsorption of dye-water(AI-Fe柱撑膨润土的制备及其对活性艳红X-3B的吸附)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2001
利用Fe3+, Al3+与碱液反应制备出OH-Fe离子、Keggin离子,并由此制备出不同Fe/(Al+ Fe)比值的Al-Fe柱撑膨润土,并对其吸附有机染料——活性艳红X-3B的效果作了研究(与其他几种改性膨润土进行了比较).结果表明:用Al-Fe柱撑膨润土的层间距被明显撑大,有机污染物的去除率高,可以替代活性炭作为吸附剂用于处理有机物废水.

Redox Reaction and Dissolution Analysis for Hollow C Nanospheres Comprising N‐Doped C Framework With Abundant Ni–Co Heteronuclear Catalysts for Highly Durable K‒Te Batteries

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Tellurium (Te), emerging as a promising alternative to sulfur (S) and selenium (Se), offers significant advantages for potassium (K) ion storage due to its comparable theoretical volumetric capacity (2619 mAh cm−3) and higher electronic conductivity (∼102 S m−1), which promotes rapid charge transfer and improves reaction kinetics.

非线性随机振动系统对非高斯激励的响应

open access: yes四川大学学报. 自然科学版, 1999
用推广了的等效线性化法,计算具有泊松分布的随机脉冲过程(非高斯)激励的非线性系统的随机响应.将传统的Ito随机微分方程中的Wiener过程增量,用复合泊松过程增量代替,得到矩方程,再用线性系统的随机微分方程替代非线性系统的随机微分方程,以使两系统的矩方程在四阶矩上具有最小误差,用Dufing振子作算例 ...

Adaptability of Governance Structures and Processes for Sustainable Livestock in Jalisco, Mexico

open access: yesReview of Policy Research, Volume 43, Issue 2, March 2026.
ABSTRACT Global increases in meat production have intensified interest in alternative livestock systems that can address environmental, social, and economic challenges. Transitioning toward sustainable livestock (SL) systems requires adaptive governance arrangements that integrate local knowledge into broader policy design.

有机肥替代化肥氮素对麦田土壤碳氮迁移特征的影响

open access: yesShuitu Baochi Xuebao, 2019
利用小麦田间试验,设置控释尿素(CRU)、有机肥(OF)替代30%,50%,70%控释尿素氮量处理,并以普通尿素(Urea)为对照,研究等氮条件下有机肥替代不同比例化肥氮素对土壤碳氮迁移特征及小麦产量的影响。结果表明:有机肥处理小麦总生物量较Urea显著增加13.83%~17.57%,籽粒产量增加1.6%~10.5%,随有机肥替代化肥氮素比例增加,籽粒增产效应降低,70% OF与Urea无显著差异,但显著低于CRU处理。CRU、30% OF和50% OF处理氮素农学效率较Urea显著提高90.2 ...
