Drivers and barriers to energy-efficient technologies(eeTs)in eU residential buildings

能源与人工环境(英文) 2021年第3期2卷 290-301页

作者： clara Camarasa Lokesh Kumar Kalahasthi Leonardo Rosado Sustainable Building Group Chalmers University of TechnologyGothenburgSweden

To achieve carbon targets,the european Union(eU)aims to promote nearly zero-energy buildings(nZeB).To enable the necessary transition,technical solutions need to converge with socio-economic factors,such values and awareness of stakeholders involved in the decision-making *** this light,the aim of this paper is to characterise perceived drivers and barriers to nine energy-efficient technologies(eeT),according to key decision-makers’and persuaders of the technology selection in the eU residential building *** are collected across eight eU countries,***(Be),Germany(De),Spain(eS),France(FR),Italy(IT),Netherlands(NL),Poland(PL),and United Kingdom(UK).The stakeholders’selected are architects,construction companies,engineers,installers and demand-side *** from a multi-country survey is analysed to calculate the share of 15 drivers and 21 barriers(aggregated to 5 groups),being selected for each eeT and *** 5 groups considered to analyse drivers and barriers are environmental,technical,economic,social,*** perceived barriers and drivers were further studied for their association across the countries using the Pearson’s Chi2 and a Cramer’s V *** results demonstrate that across all eeTs and countries,the technical and economic driver groups are perceived to have the highest potential to increase the implementation rate of *** terms of barriers,economic aspects are seen as the foremost reason that eeT are not scaling *** both drivers and barriers legal aspects are the least often *** overall the barrier groups show significant variation across countries compared to driver *** findings provide an evidence-basis to better understand arguments in favour and against specific eeTs and,in this way,support policy makers and other interested parties to increase the market share of the selected solutions.

Arnica montana experimental studies:confounders and biases?

引用

Journal of Integrative Medicine 2018年第2期16卷 72-76页

作者： Bellavite Paolo Marzotto Marta Bonafini clara Department of Medicine University of Verona

Arnica montana is a popular traditional remedy widely used in complementary and alternative medicine, in part for its wound-healing properties. The authors recently showed that this plant extract and several of its homeopathic dilutions are able to modify the expression of a series of genes involved in inflamma- tion and connective tissue regeneration. Their studies opened a debate, including criticisms to the ＂errors＂ in the methods used and the ＂confounders and biases＂. Here the authors show that the criticisms raised on methodology and statistics are not consistent and cannot be considered pertinent. The present comment also updates and reviews information concerning the action of A. montana dilutions in human macrophage cells while summarizing the major experimental advances reported on this interesting medicinal plant.

Objectives:To compare the depth of thermal necrosis after use of bipolar resection and vaporization technique comparing intra-individually bipolar loop and bipolar button ***:Transurethral resection and vaporization of the prostate was performed in 55 male patients(260 specimens in total).In a standardized procedure,a bipolar resection loop was used for resection,and a bipolar button electrode was used for *** electrodes were applied in each patient,either in the left or in the right lateral *** depth of necrotic zones in the resected or vaporized tissue of each patient was measured in a standardized way by light ***:The mean depth with standard deviation of thermal injury caused by the loop electrode was 0.0495±0.0274 *** vaporization electrode caused a mean thermal depth with standard deviation of 0.0477±0.0276 *** mean difference of necrosis zone depths between the two types of electrodes(PlasmaButtoneresection loop)was 0.0018 mm(p=0.691).Conclusion:For the first time,we present directly measured values of the absolute necrosis zone depth after application of plasma in the transurethral treatment of benign prostatic *** measured values were lower than in all other transurethral *** procedures of measurement and evaluation allow a statistically significant statement that the low necrosis depth in bipolar procedures is independent of the applied electrodes.

A species-transport model for circulation in a leading-edge vortex

Advances in Aerodynamics 2022年第1期4卷 762-779页

作者： clara Giner-Morency Jaime G.Wong Department of Mechanical engineering University of AlbertaEdmontonT6G 1H9Canada

In this study,we propose a model to predict circulation growth along the span of a rotating wing,in which circulation transport is represented as species *** particles entering the vortex shear layer at the leading edge are initialized as vorticity-containing mass and are advected by the flow along the span.A circulation budget is presented,consisting of a generation and transport term,the latter derived from the vorticity transport equation,which leaves only two unknowns for the modeller to determine:the shear-layer thickness and the spanwise flow *** find that the model is insensitive to the value chosen for the shear-layer thickness,as varying the thickness by an order of magnitude only changes the output by a few ***,we use Bernoulli equation in a rotating coordinates system as a basic model for spanwise *** verify the accuracy of the model,the predicted circulation values are compared against experimental circulation values and show good agreement to measurements close to the axis of rotation,which corresponds to the spanwise locations at which the spanwise flow model best matches experimental *** is suggested,therefore,that this model produces accurate results subject to an appropriate spanwise flow model.

This article traces the liife of Qu Fengzhu(1860-1927),a native of Panyu,Guangdong,with special fOcus on her Zhijia yaoyi(Basic principles of household management).Whereas many women from elite families in late imperial China emphasized the importance of their sons studying hard in order to secure a place in the government or to live with dignity,Qu Fengzhu fbcused on seeking and managing wealth properly to sustain the family *** in the greater Canton area loaded with heavy commercial activities and Fast-West interaction opportunities,as well as w让nessing the political and social transition from the imperial era to the republican era,Qu Fengzhu gave very pragmatic advice to her o伍pHng without elaborating much on high-sounding truths and *** set four rules for her children to follow and emphasized the imporance of diligence and *** a flourishing commercial world,the relatively conservative arguments on wealth management contained in Zhjjia yaosomehow incorpomtes moral *** makes its authors words carry weight and significance.

过去几年奢侈品市场正在发生巨变。技术革新以及“平易近人的奢侈”概念的兴起深刻地影响着诸多奢侈品牌。品牌专卖店正逐渐成为消费者体验品牌的场所。本研究将探索华伦天奴应该如何继承其品牌内涵,同时适应新的市场变化。一直以来华伦天奴的主要客户群是成熟而优雅的中年女性,为他们出席高端活动,如鸡尾酒会,晚宴等提供相应的服饰。现如今,这是相对小众的一个市场。本研究的第一个假设是华伦天奴只专注于高端服饰的作风可能成为其在新环境下进一步发展的障碍。华伦天奴也应该照顾到女性在其他各种场合的着装需求,并着眼于为客服提供整体穿衣方案。对过去5年公司产品手册的深人研究将帮助理解公司在迎合用户多种需求和产品设计方面是否有所改变。同时,对不同品类产品销售数据的分析将帮助理解它们各自的销售表现

想让我们的身体正常运作,大约需要30种维生素和矿物质。食物给予我们能量,但同样重要的是,它们还能为我们输送维生素和矿物质。任何身体功能,都至少依赖于这些化合物中的一种,研究认为,其中有大约30种是不可或缺的。它们帮助我们的心脏跳动、肺部呼吸。它们使我们的身体能生成新的肌肉、皮肤和骨骼细胞。它们还辅助神经向大脑发送信号,让免疫系统对抗外敌。没有了它们我们简直无法生存。

科学家启动了无数的计划,试图将各类行星的样本带回地球。经历漫长的太空探索后,很多人都觉得能造访月球、小行星和其他行星已经是一件很棒的事了,要是能带一块它们的样本回来就更妙了。将天外样本带回地球,科学家就能施展全套的实验技术研究它们,如果只是在太空,能用于研究的分析手段就会十分有限。
