Petrological implication of wagnerite-Ma5bc in the quartzofeldspathic gneiss, Larsemann Hills, East Antarctica

引用

Progress in Natural science:Materials International 2005年第6期15卷 523-529页

作者： edward s. GREW 5790 edward T. Bryand Research Center Department of Earth sciences Maine 04469-5790 Orono UsA University of Maine

Wagnerite-Ma5bc polytype is found in a gneiss associated with cordierite-prismatine-bearing gneiss, northern stornes Peninsula, Larsemann Hills, East Antarctica. Wagnerite coexists with apatite and both of them are present as rock-forming minerals. Ca depletion is not essential to the formation of wagnerite; sufficient Mg, P and F components, and a relatively low Ca/Mg ratio is critical, otherwise only apatite crystallizes. strong anatexis of the quartzofeldspathic gneiss of the area results in differentiation and separate enrichment of leuco- and melanocratic components. P and F tend to accumulate in the mafic-rich melanocratic component, and when their abundance reaches certain concentration, wagnerite forms. It is perhaps the chemistry of the setting that controls the appearance of wagnerite, whereas the PT condition is responsible for the variety of wagnerite polytype. A disordered polytype crystallizes at relatively high temperature, then cools down slowly and transforms into one of the ordered polytypes, in this case, the Ma5bc polytype.

为降低岭南地区农宅因围护结构霉变带来的安全和健康危害，在实地取样和正交实验的基础上研究温度和湿度对该地区优势菌生长的影响，并对培养基上霉菌的生长特性进行拟合优选分析，以期扩充建筑中优势霉菌生长特性数据库，为预测霉菌在波动温湿度条件下的生长风险提供理论支持。首先，用刮擦法在岭南典型农宅获取霉斑样品，采用高通量测序法鉴定优势菌种类；然后，在恒温培养箱中设置22、26、30℃和60%、70%、85%的温湿度组合，研究优势菌在马铃薯葡萄糖琼脂（Potato Dextrose Agar，简称PDA）培养基上的生长特性，并建立其随时间和温湿度变化的动力学模型；最后，在人工气候室中设置26、30、34℃和50%、90%的环境温湿度组合，研究优势菌在常用建材上的生长特性。结果表明：岭南地区以大白灰为内饰面材料的农村住宅围护结构表面的优势菌属为枝孢霉Cladosporium、Neoderiesia和枝顶孢霉Acremonium;26℃是枝孢霉最容易生长繁殖的环境温度；木材和PDA上环境相对湿度越高，枝孢霉生长越快；Gompertz模型和响应面模型能较好地表征枝孢霉在培养基上的生长特性。

Migration departure strategies of shorebirds at a final pre-breeding stopover site

Background: Departure decisions and behaviors of migratory birds at stopover sites are expected to maximize fit?ness by trade?offs among avoiding predators, optimizing refueling(energy) capacity, and matching other life?history events. We predict that species with different body sizes and migratory destinations will exhibit different behaviors when departing from the same stopover site. We also predict that with strong time constraint at the final pre?breed?ing stopover site, departure decisions may be less sensitive to exogenous factors, such as wind condition, compared to other stopover or nonbreeding ***: We recorded migratory departures of four shorebird species, i.e. Eurasian Curlew(Numenius arquata), Bar?tailed Godwit(Limosa lapponica), Great Knot(Calidris tenuirostris), and Grey Plover(Pluvialis squatarola), at Yaluji?ang Estuary Wetlands in China, a final pre?breeding stopover site in the northern Yellow sea, from 2011 to 2014. We compared flock sizes, departure time and departure directions between species, and investigated the effects of tide and weather conditions(rain and ground wind speed and direction) on the departure decision of ***: We found that larger species departed in smaller flocks and were more variable in daily departure time. Departure trajectory of all four species appeared to be influenced by coastal topography. With the east–west coast?line and intertidal mudflat on the south, birds exhibited westward or eastward deflection from the shortest migra?tory routes. Bar?tailed Godwit was the only species that deviated to the southeast and did not climb over the land. Birds avoided departure during precipitation, while their departure was not related to ground wind benefit or tidal ***: Body size among species, which influences their vulnerability to predators, might be important in shaping shorebird departure strategies. Diverse departure directions could be the result of different wind use tac?tics i

Quality and readability of online information resources on insomnia

Frontiers of Medicine 2017年第3期11卷 423-431页

The internet is a major source for health information. An increasing number of people, including patients with insomnia, search for remedies online; however, little is known about the quality of such information. This study aimed to evaluate the quality and readability of insomnia-related online information. Google was used as the search engine, and the top websites on insomnia that met the inclusion criteria were evaluated for quality and readability. The analyzed websites belonged to nonprofit, commercial, or academic organizations and institutions such as hospitals and universities. Insomnia-related websites typically included definitions （85%）, causes and risk factors （100%）, symptoms （95%）, and treatment options （90%）. Cognitive behavioral therapy for insomnia （CBT-I） was the most commonly recommended approach for insomnia treatment, and sleep drugs are frequently mentioned. The overall quality of the websites on insomnia is moderate, but all the content exceeded the recommended reading ease levels. Concerns that must be addressed to increase the quality and trustworthiness of online health information include sharing metadata, such as authorship, time of creation and last update, and conflicts of interest; providing evidence for reliability; and increasing the readability for a layman audience.
