绿色建筑(设计和施工)技术(GBT)在建筑行业被全球倡导,以解决可持续发展问题,但其实施仍面临挑战。实现可持续发展目标的挑战是GBT实施需要详细的调查研究。然而,在GBT的实施过程中有一些发展中国家对GBT的研究还很少,比如尼日利亚和加纳等。本文提到了卢旺达建筑行业的研究,旨在调查GBT在卢旺达建筑行业实施过程中遇到的重大挑战。为了实现研究目标,通过综合文献回顾,确定了26个影响因素,并对43名具有绿色建筑经验的专业人员进行了问卷调查。排名分析结果表明,其中20项因素至关重要。前三个最关键的影响因素是GBT的成本较高,缺乏政府激励措施以及缺乏融资方案(如银行参与)。比较分析表明,对于卢旺达这样的发展中国家实施GBT的最关键挑战不同于大多其他评估国家。此外,因素分析显示,20个潜在的关键因素是与政府、人、知识和信息、市场以及成本和风险5个基础因素相关。这项研究还表明,五个基础因素中最主要的是与政府有关因素,这突出了政府在促进卢旺达GBT实施方面的角色。本文通过分析GBT在发展中国家实施的挑战,增加了绿色建筑相关的理论知识,这可以帮助决策者和从业人员采取适当措施来缓解障碍,从而推动GBT的实施。

In de novo protein design one attempts to create artificial proteins with defined structure and function from first principles, usually with the help of trial-and-error procedures that scan a large number of possible amino acid sequences. Our approach to de novo protein design is based on peptide dendrimers. Dendrimers are tree-like structures that adopt a globular or disk-shaped structure as a consequence of topology rather than folding. Our peptide dendrimers are obtained by alternating alpha-aminoacids with branching diaminoacids[1].Dendrimers containing combinations of histidine, serine and aspartate display enzyme-like catalytic properties for the hydrolysis of esters, including enantiomeric discrimination[1d]. The catalytic effect involves cooperative substrate binding and catalysis by a positive dendritic effect[1d].

作者： Reinhard Boons Mark Van Iersel jean louis Genicot 不详

The laboratory of Radiation Dosimetry and Calibration of the Belgian Nuclear Research Centre (***) is using thermoluminescence dosimetry for more than thirty years for routine measurements and for R&D investigations. In 2002, it has developed an experimental device based on the optically stimulated luminescence (OSL) technique. This device is working with AL2O3:C crystals stimulated by the green line (488 nm) emitted by a 150 mW argon laser. This paper describes this device, its characteristics, some applications in space dosimetry and the R&D works initiated in this field during the next few years.

We analyze ten of the longest (127 to 230 year-long) time series of European daily temperatures available from five different Köppen-Geiger climate classes. We split these according to the level of solar cycle activity (H for “higher than median” and L for “lower than median”). This reveals coherent patterns in the temperature differences: when TH-TL?are stacked according to their calendar date, the daily averages from January 1 to December 31st disclose characteristic features in addition to the dominant annual seasonal wave, namely variations up to 2°C lasting for about 1.5 to 3 months. The five observatories at intermediate latitudes in a band from Oxford in the West to Prague in the East (same climate class) have very similar signatures. These similarities are most unlikely to be due to pure chance (confirmed by confidence levels in excess of 99% with the Kolmogorov-Smirnov and Kuiper nonparametric tests). The TH-TL patterns carry a regional signature, modulated by a more local response function. On the other hand, northern European observatories (St Petersburg and Arkhangelsk), those south of the Alps (Milan and Bologna), and the easternmost one in Astrakhan, corresponding to different climate classes, have different signatures. Similarly, preliminary study of long air pressure recordings confirms what emerges from the analysis of temperatures. These new observations lead us to conclude that the climate in different regions presents different responses to variations in solar activity. Moreover, the distributions of the lower, middle, and higher quartiles of the temperature and pressure indices in solar cycles with high versus low activity are significantly different, providing further robust statistical confirmation to this conclusion (confidence level higher to much higher than 99% using the Kuiper test).

This work simulates the dispersion and atmospheric attenuation of pollutants from the Dibamba-Douala thermal power plant. The objective of this research is to study the dispersion of air pollutants and mitigate the impact of pollutants on the populations living around the power plant. The methodology used is as follows: the Gaussian model is used for the representation of the dispersion in the form of a plume, the finite difference method for digital resolution. Finally, dispersion charts are constructed which allow the heights of the chimneys to be fixed for which the concentrations of pollutants discharged comply with ambient air quality standards. The results obtained using the simulation made in the MATLAB software version 2016 show that, for a wind regime of 1.5 m/s;we have a predicted distance of 150 m at which the concentration is canceled out. Then, for the wind speed of 2 m/s;we had a predicted distance of 125 m and finally for a wind speed of 2.5 m/s;we observed the 120 m distance at which the concentration is canceled. In addition, for the same wind regimes, the attenuation of pollutants at ground level is obtained for a height of 60 m.
