Modeling Sorption Transport In Rooms And Sorption Filtration Systems For Building Air Quality Analysis

Adsorption, desorption and chemisorption are known to impact the dispersal of volatile organic and chemically reactive compounds in buildings. These same three processes may be used to advantage to control the levels of these compounds indoors using building sorption filtration devices. To add to the understanding of these processes, to provide the means to predict the impact of these processes on human exposure and to provide the tools needed to design gaseous filtration systems to mitigate the exposure to these compounds, a general approach to modeling the dynamics of these processes is presented. Equations are presented to account for the elemental advection, diffusion, sorption, and chemical transport steps affecting single component sorption dynamics in rooms and sorption filtration systems. These element equations are based on general principles and formulated in terms of fundamental physical parameters that may be determined using standard procedures. Models to predict room and sorption filtration system dynamics are formulated using assemblages of these element equations and a series of simplified models of these systems are derived. Initial applications to model single-component sorption transport in rooms and sorption filtration systems indicate that the approach has the potential to provide accurate predictions providing the sorption and chemical characteristics of the sorbate-sorbent system being considered are well-characterized. This potential is, however, compromised by the lack (or present uncertainty) of fundamental data relating to sorption equilibrium, porous diffusion, surface chemistry, and boundary layer mass transport

Uplift of elastomeric bearings in isolated bridges subjected to longitudinal seismic excitations

Bearings are used to isolate bridge substructures from the lateral forces induced by creep, shrinkage and seismic displacements. They are set in one or two support lines parallel to the transverse axis of the pier cap and are typically anchored to the deck and to the pier cap. This detailing makes them susceptible to possible tensile loading. During an earthquake, the longitudinal displacements of the deck induce rotations to the pier caps about a transverse axis, which in turn cause tensile (uplift) and compressive displacements to the bearings. Tensile displacements of bearings, due to the pier rotations, have not been addressed before and questions about the severity of this uplift effect arise, because tensile loading of bearings is strongly related to elastomer cavitation and ruptures. An extended parametric study revealed that bearing uplift may occur in isolated bridges, while uplift effect is more critical for the bearings on shorter piers. Tensile displacements of bearings were found to be significantly increased when the isolators were eccentrically placed with respect to the axis of the pier and when flexible isolators were used for the isolation of the bridge. The results of this study cannot be generalised as bridge response is strongly case-dependent and the approach has limitations, which are related to the modelling approach and to the fact that emphasis was placed on the longitudinal response of bridges.

常低温下EGSB处理生活污水的影响因素研究

在15～26℃的常低温条件下,采用EGSB处理生活污水,考察了进水流量、回流比、液体上升流速(Vup)、温度等因素对运行效果的影响。结果表明,当温度为26℃左右时,对于9～11 L/h的低进水流量,宜采用高回流比(1.6～2.5),对COD的去除率最高可达90%;对于15～24L/h的高进水流量,宜采用低回流比(0～0.6),对COD的去除率最高可达84%;当进水流量提高至30 L/h时,不宜回流,对COD的去除率降至77%;当进水流量分别为9、11、15、24、30 L/h时,最佳Vup分别为4.0、(3.1～3.6)、(2.7～3.4)、3.0和3.8 m/h,此时对COD的去除率分别高达90%、(87%～89%)、(83%～84%)、83%和77%;在无回流的条件下,适宜的进水流量为15～24 L/h,相应的HRT为0.5～0.8 h。当温度为15～26℃时,EGSB适宜的运行条件是高进水流量(15～24L/h)、高Vup(3.0 m/h)和低回流比(0～0.6),此时对COD的去除率高达81.9%以上。     

Analysis of household access to drinking water,sanitation, and waste disposal services in urban areas of Nepal

In recent years, researchers have paid increasing attention to the provision of access to clean and sufficient drinking water, sanitation facilities, and proper waste management in developing countries. This paper examines household access to these services in urban areas of Nepal by studying the comprehensive data of the Nepal Living Standard Survey (NLSS) for the 1995-1996, 2003–2004, and 2010–2011 periods. Multinomial logit models are employed to identify and analyse potentially influential factors. We find that education levels, household wealth, and distance to markets are among the significant determinants of household access to safe and secure drinking water, flush toilets connected to septic tanks, and proper liquid and solid waste disposal. Households located in relatively developed regions, such as the Midwest and Far West, tend to have better access to these services compared to households located in the ecologically sensitive mountainous regions. Education and employment opportunities are also relevant to service access in urban areas of Nepal. Stakeholder involvement and effective governmental intervention are also necessary.     

Normen für den Konstruktiven Ingenieurbau

Codes in Structural Engineering In structural engineering codes are of essential importance. Codes have to represent accepted rules as well as the state of the art in science and technology and they provide a basis for the communication between all involved professionals. In codes of the future all procedural steps of planning have to be included – design, execution, service, conservation and dismantlement – and an integral approach to safety and quality has to be adopted. In comparison to present codes, the technical breadth and the level of detail will increase. Nonetheless, the overall aim of code writers shall be to come up with regulations that are easy to understand and to apply. Codes of the future have to (re‐)gain their significance and acceptance.
