Expansive Workflows: Downstream Coordination in the Design of Sporting Facilities

Heightening user experience is a key aim for global architecture practice Populous, specialists in designing sports and entertainment venues. Jonathan Mallie , lead principal in their New York office, outlines their working process. The digital realm plays an important part: from building information modelling, to immersive technologies that imaginatively engage communities in the creative process. But such large-scale, time-sensitive projects as the Jacksonville Jaguars American football facility in Florida would be impossible without also establishing a team spirit among all those involved.     

CO2 capture using mesocellular siliceous foam (MCF)-supported CaO

CaO is a promising material as an alternative CO₂ capture material which can be used at high temperature. However, CaO sinters to form large particles under long-term high temperature conditions, resulting in a rapid decrease of its surface area and the capacity of CO₂ capture. Incorporating CaO into inert materials is a promising strategy to enhance the performance of CO₂ capture. This work investigated a novel composite material called mesocellular siliceous foam (MCF)-supported CaO to enhance the stability and capacity of CaO-based materials for CO₂ capture. The crystal structure, surface morphology and porosity property of the developed composite materials were investigated. Thermogravimetric measurements were carried out to study the cyclic CO₂ capture performance of the MCF-supported CaO composites. The results showed that a part of CaO reacted with the silica wall, and the formation of Ca₂SiO₄ within the MCF framework limited the presence of CaO in the mesopores, thus inhibited the sintering of CaO. The sample of MCF-3CaO exhibited a better performance of CO₂ capture and long-term stability, compared with the materials prepared with lower CaO loading. This work contributes to the development of high temperature CO₂ capture adsorbents, which can be applied for decarbonizing major industrials e.g. power plant.

Contact lens profile: A tale of two countries

Introduction

This study investigated the modality, type and duration of contact lens wear as well as compliance and hygiene related issues (hand and case hygiene, use of tap water, dozing and overnight wear) in the UK and Germany. Questionnaires were collected anonymously from 417 UK and 767 German patients attending optometric practices for contact lens appointments. It is the seventh of a series of contact lens wearer profiles conducted since 2000.

Results

The proportion of rigid gas permeable lenses worn was significantly higher at 55.4% in Germany, compared to 16.1% in the UK. Overall, a significantly larger proportion of German participants used tap water to rinse their lenses and cases (P < 0.001). Also, German respondents changed their lens cases less frequently (p < 0.001). Fewer UK than German respondents stated they washed their hands before lens insertion (p = 0.009), removal (p = 0.01), before eating (p < 0.001). German participants were less likely to wash their hands before preparing food (p = 0.042) and after using the toilet (p = 0.002). The two sample groups differed significantly regarding the care regimens they used for their CLs (p < 0.001).

Conclusion

The differences between Germany and the UK highlighted in this study were caused by differences in legal regulations, plumbing and practitioners’ guidance. Although many of the questions relating to hygiene differed statistically between the two participating sample groups, the absolute differences in figures were not considered to be large.     

英国天然气市场运行机制及其对我国市场化改革的启示

英国国家平衡点(NBP)开创了以虚拟交易枢纽为核心的市场运行和定价机制,并为欧盟构建一体化的自由天然气市场提供了区域市场的范本,研究英国天然气市场的运行机制,有可能为我国天然气市场化改革和交易枢纽的构建提供启示和借鉴。为此,分析了英国国家平衡点、天然气市场和容量市场的运行机制,重点剖析了容量市场的监管和定价模型,并得出英国经验对我国天然气市场化改革的启示:(1)立法先行,管网独立,分拆纵向一体化在位者,强制让出市场份额和培养新的市场主体等改革措施值得借鉴;(2)建议将我国天然气市场化改革与行业内相关国企的混合所有制改革相结合;(3)深入研究规制经济学理论及其模型在英国的应用,有利于提升我国政府对输配气管网的监管水平;(4)我国一些省内天然气管网适合发展为以虚拟交易枢纽为基础的区域市场定价中心。结论认为:(1)虚拟交易枢纽在更大地理范围内实现了天然气的标准化,有利于提高市场的运行效率、透明度、流动性和公平性;(2)虚拟交易枢纽的运行和交易较为简单,但输气管网容量市场的定价理论相对复杂,监管难度较大;(3)虚拟交易枢纽的价格仅能反映区域市场内的供需情况。

Evidence for a Negative Correlation between Human Reactive Enamine-Imine Intermediate Deaminase A (RIDA) Activity and Cell Proliferation Rate: Role of Lysine Succinylation of RIDA

Reactive intermediate deaminase (Rid) proteins are enzymes conserved in all domains of life. UK114, a mammalian member of RidA subfamily, has been firstly identified as a component of liver perchloric acid-soluble proteins (L-PSP). Although still poorly defined, several functions have been attributed to the mammalian protein UK114/RIDA, including the reactive intermediate deamination activity. The expression of UK114/RIDA has been observed in some tumors, arousing interest in this protein as an evaluable tumor marker. However, other studies reported a negative correlation between UK114/RIDA expression, tumor differentiation degree and cell proliferation. This work addressed the question of UK114/RIDA expression in human non-tumor HEK293 cell lines and in some human tumor cell lines. Here we reported that human RIDA (hRIDA) was expressed in all the analyzed cell line and subjected to lysine (K-)succinylation. In HEK293, hRIDA K-succinylation was negatively correlated to the cell proliferation rate and was under the control of SIRT5. Moreover, K-succinylation clearly altered hRIDA quantification by immunoblotting, explaining, at least in part, some discrepancies about RIDA expression reported in previous studies. We found that hRIDA was able to deaminate reactive enamine-imine intermediates and that K-succinylation drastically reduced deaminase activity. As predicted by in silico analysis, the observed reduction of deaminase activity has been related to the drastic alterations of hRIDA structure inferred by K-succinylation. The role of hRIDA and the importance of its K-succinylation in cell metabolism, especially in cancer biology, have been discussed.     

Measurement of CO2 emissions from road freight transport: A review of UK experience

It is possible to estimate CO₂ emissions from road freight transport in different ways, depending on the definition of trucking activity, the degree of reliance on survey, vehicle test-cycle and traffic count data and the geographical scope of the calculation. The emergence of differing road freight-related CO₂ estimates from official sources and revisions to statistical series can frustrate the policy-making process and erode the confidence of industry stakeholders in the validity of the figures. Using UK data, this paper examines the various methods of carbon auditing road freight transport at the national level and compares the results both for a single year (2006) and over a time period. It highlights a series of statistical anomalies and approximations and tries to explain discrepancies that have arisen in the UK data sets. A concluding section considers the general lessons that can be learned from the recent UK experience in this field.
