1Noninvasive Hemodynamic Monitoring for Heart Failure:A New Era of Heart Failure Management显示文摘Despite the development of noninvasive tools as echocardiography,right-sided heart catheterization remains an integral part of the cardiovascular evaluation.In the last decade,better understanding of the hemodynamic process before heart failure decompensation led to improvement of outpatient strategies to prevent it.Advances in implantable wireless technology now allow frequent and direct measurement of intracardiac fi lling pressures,which can be monitored by health care providers to help tailor therapy to reduce fi lling pressures and hospital readmission rates.Gabriel A.Hernandez Viviana Navas Sandra Chaparro 2015Cardiovascular Innovations and Applications2015,,B10:1

3澳大利亚不同品种甜羽扇豆消化能测定及其消化能预测方程的研究进展显示文摘试验选用63头体重49.5±0.5kg的公猪(长白×大白)对不同品种不同生长区域狭长叶羽扇豆的消化能差异进行分析,并根据羽扇豆的物理和化学组分建立消化能的预测方程。试验猪按4×2双因子设计随机分配,4个品种(Belar、Coromup、Manudelup和Tanjil),2个生长地区(西澳大利亚的南北农业区)。另外,采用小麦对照作为羽扇豆消化能统计的参考。羽扇豆用锤片粉碎机粉碎,用4mm筛片筛选,平均粒度为888μm。试验中日粮能量水平为维持能的3倍[3×(0.458×BW^(0.75))/消化能×0.97],范围从13.3~15.7MJ/kg不等,平均值为14.2MJ/kg。羽扇豆的品种对消化能影响极显著(P<0.01),而且北方农业区的羽扇豆消化能显著高于南方农业区同种羽扇豆(P<0.01)。羽扇豆消化能的差异主要是由于北方农业区Coromup羽扇豆的高消化能引起的。试验结果表明,在羽扇豆的生长中,遗传因素和环境条件对生长猪利用羽扇豆有显著的影响。简单回归分析表明,消化能的预测可能与豆皮比例[R^2=0.88,相对标准偏差(RSD)=1.11 6,P<0.001]、千粒重(R^2=0.95,PSD=1.072,P<0.001)和可溶性阿拉伯木聚糖含量(R^2=0.64,RSD=1.072,P<0.05)有关。多重线性分析则将总非淀粉多糖(R^2=0.96,PSD=1.187,P<0.01)和可溶性非淀粉多糖(R^2=0.95,RSD=1.200,P<0.01)同豆皮比例和千粒重一起考虑,这明显提高了预测的精确性。结果显示,羽扇豆的消化能达到2.4MJ/kg,而且根据羽扇豆的物理和化学特性可预测其消化能值,且精确度高。J.C.Kim B.P.Mullan J.M.Heo A.Hernandez J.R.Pluske 赵颖 2012饲料与畜牧(新饲料)2012,,9:0
4Microbial and size characterization of airborne particulate matter collected on sticky tapes along US–Mexico border显示文摘Particulate matter(PM) emissions from various sources can affect significantly human health and environmental quality especially in the Chihuahuan Desert region along US–Mexico border. The objective of this study was to use the low-cost sticky tape method to collect airborne PM for size characterization and identification of fungal spores. Sticky tape samplers were placed at 1.0 and 2.0 m above the ground surface at experimental sites in Ciudad Juárez, Mexico and at 0.6, 1.2 and 1.8 m at New Mexico sites, USA. Soil samples were collected in both countries to determine fungal diversity, texture and moisture content Dust particles collected from all of the experimental sites had a dominant texture of clay(< 0.002 mm). The dominant textures identified from soil samples collected from the US and Mexican sites were loam and sandy clay loam, respectively. Alternaria, Penicillium and Fusarium were frequently found funguses in the US sites while Alternaria and Aspergillus were commonly observed in the Mexican sites. The sticky tapes also showed a similar diversity of fungal microorganisms present in the airborne PM at both Mexico and US sites Alternaria, Penicillium and Aspergillus were the three groups of airborne fungal microorganisms consistently present in the US and Mexican sites. The low-cost sticky tape method has the potential to be used for characterizing different airborne microorganisms and dust particles.Amir Gonzalez-Delgado Manoj K.Shukla David W.DuBois Juan P.Flores-Mdrgez Joel A.Hernandez Escamilla Evangelina Olivas 2017Journal of Environmental Sciences2017,29,3:0
5如何设计插入管式换热器显示文摘插入管(也称刺刀管-译注)式换热器特别适用于中等或高真空下的蒸汽冷凝过程,也适用于冷热流体间存在很大温差的热过程。A.Hernandez—Guerrero A.Macias—Machin 郭崇志 1992化工设计1992,2,4:0
