A simplified procedure for determining indoor daylight illuminance using daylight coefficient concept

The first step in evaluating the visual performance and energy efficiency provided by daylight requires an accurate estimation of the amount of daylight entering a building. The actual daylight illuminance of a room is mainly influenced by the luminance levels and patterns of the sky in the direction of view of the window at that time. The daylight coefficient concept, which considers the changes in the luminance of the sky elements, offers a more effective way of computing indoor daylight illuminances. Recently, Kittler et al. have proposed a new range of 15 standard sky luminance distributions including the CIE (International Commission on Illumination) standard clear sky. Lately, these 15 sky luminance models have been adopted as the CIE Standard General Skies. This paper presents a graphical method to calculate interior illuminance for the CIE standard clear sky using the daylight coefficient approach. The simplified techniques in the form of a nomograph and Waldram diagram were established and described. The performance of the proposed approach was evaluated against the results obtained by an independent calculation approach and a computer simulation program. It was shown that the daylight illuminances estimated by our graphical tool were in reasonably good agreement with those produced from the other two methods. The findings provide building professionals and students a reliable and simple alternative that incorporates the daylight coefficient concept to estimate the interior daylight illuminance and assess daylighting performance.

Oncogenic MicroRNAs Characterization in Clear Cell Renal Cell Carcinoma

A key challenge for the improvement of clear cell renal cell carcinoma (ccRCC) management could derive from a deeper characterization of the biology of these neoplasms that could greatly improve the diagnosis, prognosis and treatment choice. The aim of this study was to identify specific miRNAs that are deregulated in tumor vs. normal kidney tissues and that could impact on the biology of ccRCC. To this end we selected four miRNAs (miR-21-5p, miR-210-3p, miR-185-5p and miR-221-3p) and their expression has been evaluated in a retrospective cohort of formalin-fixed paraffin-embedded (FFPE) tissues from 20 ccRCC patients who underwent surgical nephrectomy resection. miR-21-5p and miR-210-3p resulted the most significantly up-regulated miRNAs in this patient cohort, highlighting these onco-miRNAs as possible relevant players involved in ccRCC tumorigenesis. Thus, this study reports the identification of specific oncogenic miRNAs that are altered in ccRCC tissues and suggests that they might be useful biomarkers in ccRCC management.     

基于泥沙冲淤数值模拟的水库调度方案研究

以东台子水库为研究对象,基于一维不饱和全沙数值模型,研究蓄洪运用方案、蓄洪排沙运行方案、分阶段蓄洪运用方案、蓄清排浑运用方案等四种水库调度方式下的泥沙淤积情况,力图在兴利防洪的基础上尽量利用弃水排沙,保持有效库容。对不同运行年限的淤积量、水库库容变化和排沙比等要素的模拟研究表明,分阶段蓄洪运用或蓄清排浑运用方案更有利于保持有效库容,对延长水库使用寿命具有一定作用,是较优的水库排沙优化调度方案。     

基于74LS162数字钟设计及时间校准研究

数字钟电路一般设有校时功能。本文基于不截断正常的计数通路和加入校时脉冲信号对数字钟进行校时。采用了将所有计数器芯片74LS162的计数时钟输入端CP端均接同一个CP信号、将所有计数器芯片的置数端连在一起的方法。所设计的电路仅通过开关的接通或断开便可调整数字钟的时间值,而且时、分、秒的校时操作是任意的和互不干扰的。电路的...     

电动挖掘机在山西正中副立井井筒施工中的应用

在传统的立井井筒施工中,清底是采用人工手动作业方式,装岩是人工手镐配合抓岩机的作业方式。这种施工工艺费工费力费时,且存在很大的施工安全隐患,已经相对落后。而随着科技发展采用电动挖掘机立井清底及配合抓岩机装碴则实现了立井施工全机械化作业,与传统的立井筒施工工艺相比,具有省工、省力、省时、安全快捷等优点。在将来的立井筒施工...
