利用水泥回转窑处理危险废物

open access: yes节能环保, 2022
回转窑作为中国水泥行业的重要组成部分,它对能源消耗、环境保护和经济效益都具有举足轻重的作用。而泥料在骨粉制备过程中,由于颗粒较大,需要大量投放于专用泥浆搅拌设备内进行物料分离与运输处理,为了提高破碎比降低能耗尽可能地减少碎裂率及热损,因此需要对物料进行合理的泥浆分离,来确保回转窑灰渣成型过程的安全和高效。目前,中国水泥行业中由于生产工艺流程复杂、料水液分布不均和处理不当导致事故频发,而回转窑泥料处理危险废物预热器是一种可回收、易清理的物料干燥机,它可以将颗粒状或粒径较大的固体悬浮物转化为液滴 ...

浅析矿山井巷掘进施工中危险源的判别

open access: yes工程建设, 2021
矿山井巷施工过程中,由于矿山作业本就存在危险性,使得施工期间存在各种危险因素,对人员作业造成威胁。危险因素引发安全事故,不但影响工程进度,还会造成严重的人员伤亡事故。对此,需要针对矿山井巷掘进施工进行仔细研究。文中通过分析施工中存在的危险源,找寻其产生原因,并根据不同危险源对其进行判别。最大程度减少井巷掘进施工的危险性,保障施工获得危险预防,减少事故发生概率。

Impacts of livestock grazing on blue‐eared pheasants (Crossoptilon auritum) survival in subalpine forests of Southwest China 散放家畜对中国西南山地亚高山森林雉类蓝马鸡的影响

open access: yesIntegrative Conservation, Volume 2, Issue 4, Page 201-213, December 2023., 2023
Livestock disturbances decreased the area of suitable habitat of forest pheasants by 14.28% in 7 years. Livestock activities remarkably increased the nest failure rate (by 2.18 times) of forest pheasants. Abstract The degradation and fragmentation of natural habitats, driven largely by anthropogenic activities such as grazing, represent growing ...

A network meta‐analysis of association between cardiometabolic risk factors and COVID‐19 outcome severity 心血管代谢危险因素与COVID‐19严重程度关联的网络荟萃分析

open access: yesJournal of Diabetes, Volume 15, Issue 11, Page 968-977, November 2023., 2023
Highlights Among 301 studies, diabetes mellitus was the most studied cardiometabolic risk factor. In the network meta‐analysis, cerebrovascular disease had the highest impact (relative risk [RR] 1.69; 95% CI, 1.65–1.73) on COVID‐19 outcomes compared to other cardiometabolic risk factors.

Associations of blood biomarkers with arterial stiffness in patients with diabetes mellitus: A population‐based study 糖尿病患者血液生物标志物与动脉硬化的关系: 一项基于人群的研究

open access: yesJournal of Diabetes, Volume 15, Issue 10, Page 853-865, October 2023., 2023
Highlights Few studies have investigated the association of large‐scale biomarkers and pulse wave velocity (PWV) among diabetic patients. This study investigates the relationships of serum laboratory tests with PWV and explored the associations between PWV and all‐cause mortality among diabetic patients.

Metrics for quantifying how much different threats contribute to red lists of species and ecosystems

open access: yesConservation Biology, Volume 37, Issue 5, October 2023., 2023
Abstract Red lists are a crucial tool for the management of threatened species and ecosystems. Among the information red lists provide, the threats affecting the listed species or ecosystem, such as pollution or hunting, are of special relevance.

Prediction of postnatal circulation in pulmonary atresia/critical stenosis with intact ventricular septum: systematic review and external validation of models

open access: yesUltrasound in Obstetrics &Gynecology, Volume 62, Issue 1, Page 14-22, July 2023., 2023
ABSTRACT Objective A favorable postnatal prognosis in cases of pulmonary atresia/critical stenosis with intact ventricular septum (PA/CS‐IVS) is generally equated with the possibility of achieving biventricular (BV) repair. Identification of fetuses that will have postnatal univentricular (UV) circulation is key for prenatal counseling, optimization of
