A prospective study evaluating the correlation between local weather conditions, pollen counts and pruritus of dogs with atopic dermatitis

open access: yesVeterinary Dermatology, Volume 35, Issue 5, Page 500-507, October 2024.
Abstract Background Canine atopic dermatitis (cAD) is a hereditary, generally pruritic and predominantly T‐cell‐driven inflammatory skin disease, involving an interplay between skin barrier abnormalities, allergen sensitisation and microbial dysbiosis.

人工气候箱在“六淫”研究中的应用 [PDF]

open access: yes, 2014
“六淫“的发生与气候密切相关,人工气候箱可以模拟出自然界可能出现的各种气候类型,为“六淫“实验研究的最重要手段之一,已在风、寒、湿、燥邪等研究中取得一定成果。然而由于气候对人体的影响规律尚不明确,所以研究中还存在同种邪气气候箱条件设置各异、动物在气候箱放置时间各异等问题,也是“六淫“研究今后要深入探讨的问题。认为随着人工气候箱的发展,可以模拟出更精确、复杂的气候环境,可望在“六淫“和其他气候相关科研中发挥更大作用。国家自然科学基金资助项目(81302876); 福建省自然科学基金资助项目 ...

Patterns of recovery in extant and extirpated seabirds after the world's largest multipredator eradication

open access: yesConservation Biology, Volume 38, Issue 4, August 2024.
Abstract Eradicating invasive predators from islands can result in substantial recovery of seabirds, but the mechanisms that drive population changes remain poorly understood. Meta‐analyses have recently revealed that immigration is surprisingly important to the recovery of philopatric seabirds, but it is not known whether dispersal and philopatry ...

Influence of microclimate and forest management on bat species faced with global change

open access: yesConservation Biology, Volume 38, Issue 4, August 2024.
Abstract Climate refugia, areas where climate is expected to remain relatively stable, can offer a near‐term safe haven for species sensitive to warming temperatures and drought. Understanding the influence of temperature, moisture, and disturbance on sensitive species is critical during this time of rapid climate change.

Dutch landscapes have lost insect‐pollinated plants over the past 87 years

open access: yesJournal of Applied Ecology, Volume 61, Issue 6, Page 1323-1333, June 2024.
This study implies that Dutch landscapes are losing insect‐pollinated plant species, which is likely due, at least in part, to the decline in pollination services. Our results of quantifying the decline in insect‐pollinated plants support the necessity and urgency of taking conservation initiatives.

Hydrothermal synthetic ZnAl_2O_4 and Humidity sensing properties research [PDF]

open access: yes, 2012
以Al2(SO4)3和zn(nO3)2为原料,采用水热法合成铝酸锌微粉体,通过扫描电镜和Xrd分析发现znAl2O4晶型良好,粒径小,呈纤维状均匀分布;进一步研究湿敏特性,结果表明:测试频率对阻抗-相对湿度(rH)特性曲线影响较大,阻抗随频率的增加而迅速减小,10kHz时在33%~95%的范围内曲线的线性度好,在相同的湿度下,试样的电容随频率的增加而减小,在低频100Hz下,电容随相对湿度的升高而增大。A simple hydrothermal was developed to fabricate ...

Three major steps toward the conservation of freshwater and riparian biodiversity

open access: yesConservation Biology, Volume 38, Issue 3, June 2024.
Abstract Freshwater ecosystems and their bordering wetlands and riparian zones are vital for human society and biological diversity. Yet, they are among the most degraded ecosystems, where sharp declines in biodiversity are driven by human activities, such as hydropower development, agriculture, forestry, and fisheries.

高海拔外绝缘研究中的湿度问题

open access: yesGaoya dianqi, 1987
本文详细论述了空气的水汽部分压力、绝对湿度、相对湿度和比湿之间的关系,以澄清在高海拔外绝缘研究中在选用湿度参效上的模糊概念及错误。本文还给出了在非标准大气压力下计算湿度参数的湿度图,建议取代IEC标准和国标GB311类似的用干泡和湿泡温度计算绝对湿度图。
