Abstract:
The paper is devoted to study of the cleaning a microchannel contaminated by solute particles deposited on channel walls. The main and the most common cause of microchannel clogging is sorption of solute particles on channel walls or “physical sorption”. In this paper, we study the problem of the drift of solid non-interacting particles into a microchannel, which can stick to its walls due to Van der Waals interactions and break away from the wall due to viscous stress. A constant pressure drop is fixed between the inlet and the outlet of the channel. At the initial time moment, the channel walls are contaminated with adhering particles, i.e. the form of walls affects the formation of the flow structure through the channel. Over time, under the action of viscous stress the particles detach from the channel walls, thus cleaning occurs. The interaction of the detached particles with the flow is taken into account within the Stokes approximation. In addition, the model takes into account random walks caused by diffusion. The problem is solved numerically in the framework of the random walk model. The evolution of the fluid flow in the channel during its cleaning is obtained. The dependences of the concentration of settled particles on the flow rate and the strength of the Van der Waals interaction between particle and wall are determined. The dependence of the flow rate through the channel cross section on the concentration of settled particles was investigated. The channel cleaning time was estimated.

Abstract:
This paper presents an experimental investigation into the seismic behaviour of timber shear walls fastened with nails alone or with nails in combination with wood adhesive. The responses of both types of shear walls were determined under slow, quasi-static racking loads and also under dynamic, earthquake-induced conditions. The experimental results showed that the introduction of the adhesive makes shear walls much stronger but also more brittle than conventional nailed walls. It was observed that shear walls incorporating nails and adhesive behaved almost linearly to failure. To obtain the most out of the adhesive capacity, however, the wood framing should be designed with special attention to the connections between framing members and the anchoring of the wall's base plate. These details control the capacity of the frame to sustain the loads induced by the stiffer adhesive joints. Key words: adhesive, earthquake, tests, timber construction, shear walls, wood.

Abstract:
This thesis is an investigation in taking the architectural element â wallâ and celebrating it in the design of a building.

Walls are necessary elements in the urban fabric, and as such, should be celebrated. They enrich the space that they surround and enrich that which surrounds them as part of the urban fabric.

The project involves first creating walls with presence, then enclosing them in a manner that reveres them, that preserves their significance and emphasizes their presence.

Abstract:
"Edge. a. The line of intersection of two surfaces. b. A rim or brink. c. The point at which something is likely to begin. d. The area or part away from the middle; an extremity. e. A dividing line; a border." Edges are linear elements that create boundaries between two entities and linear breaks in continuity: shores, railroad cuts, walls. They act as lateral references rather that coordinate axes. "Those edges seem strongest which are not only visually prominent but also continuous in form and impenetrable to cross movement. An edge may be more than simply a dominant barrier if some visual or motion penetration is allowed through it then it becomes a seam rather than a barrier, a line of exchange along which two areas are sewn together." In our built environment an edge is defined and made permanent by the presence of a wall just as a line defines an edge on paper. Walls are the physical as well as the metaphorical representation of an edge. This thesis will examine the edge at the urban-suburban threshold of a city and private-public threshold of a neighborhood.

A higher level of complexity is possible by combining more than one idea as long as the order of the elements is readable in each built condition. Order is possible at any level of complexity. The more complex the greater the need of order. Order can be the relationship of a limited set of elements that inform and reform each other.

Abstract:
We are all influenced by memories when we pursue acts of creation. However, these reminiscences are often fleeting and elusive; they rarely are formalized, nor are they explicit in the final artifact. This work is based on a concrete representation of a childhood memory: the map of a city. The thesis explores ways to design and construct a place where others could, in turn, create their own memory. This place is located in Alexandria, VA, on South Fairfax Drive. It is an integrated mixed use program (Retails on the lower and ground levels, and residences on the 2 upper levels). This experimentation invites further questions. How strictly should the concrete representation of the memory guide the design? What are the qualities of the spaces resulting of such rules? How to engage in the tension between the explicit memory's realm and the contemporary world? How to express their respective materiality? |From| Memory of Walls |to| Walls of Memory

Abstract:
The photographer discusses work in “Hearing Through Walls”, a Masters of Fine Arts thesis exhibit held at downtown Tipton Gallery from February 19th through March 2nd, 2018. The exhibition consists of 15 archival inkjet prints and one two-channel video piece, representing the artists three-year exploration into narrative forms in image making. Using non-traditional approaches to photographic portraiture and experimental exhibition layout, the artist forms questions around themes of domesticity, lost youth, and American masculinity. Among these themes is an investigation into photographic issues, including the cultural role that photographs play in perpetuating, miming, and disrupting the facades of everyday life. Non-photographic influences are listed, including the paintings of Edward Hopper and the filmmaking of Paul Thomas Anderson. Historic and contemporary photographic influences included are Garry Winogrand, William Eggleston, Philip-Lorca Dicorcia, and Katy Grannan.

Abstract:
Effusion cooling is one of the most effective techniques to prevent combustor liner from being damaged. As effusion-cooled liners are comprised of a large number of sub-millimeters closely-spaced holes, full 3D numerical simulations of the combustion chamber are still unaffordable. Thus, aero-thermal models are needed to describe the main flow-liner interaction. The aim of this paper is to provide a homogeneous wall model for gas turbine combustor liners based on wall-function similarities. In order to develop such a model, a numerical database was built up covering a wide range of interest for gas turbine applications. The model proposed here consists of two modified wall-functions for both sides of a liner and an analytical model to take into account the heat exchange within the holes. As holes are not reproduced and coarse near-wall grids are sufficient, the computational cost of this methodology is very low. The performance and limitations of the model are discussed. The model has proved satisfactory in assessing the effect of a liner on the surrounding and vice-versa. Although discrepancies were observed for the first rows, momentum and heat fluxes between the flow and the impinged wall are reproduced with a good level of agreement. Overall effectiveness is predicted with a mean relative error of less than 5%.

Grant, Charles. Diaphragm Walls as Permanent Basement Walls in Regions of High Seismicity. Deep Foundations Institute, June 2018. http://dx.doi.org/10.37308/cpf-2012-slwl-1.

Full text
Abstract:
Reinforced concrete structural slurry walls have been used in the United States since the early 1960s. The typical practice, and one that makes the economics of slurry walls particularly attractive, is to design the walls to act as both temporary excavation support and permanent basement walls. They often serve as multi-story basements and below grade parking for buildings, for tunnels, subway stations, and other buried structures. One of the early applications was for a foundation for a subway station in San Francisco, but for the most part they have been used more extensively in regions of low seismicity. The purpose of this report is to investigate the requirements for extension of this practice to more common use in regions of high seismicity. Structural slurry walls are concrete walls constructed below the ground surface. In slurry wall construction, a trench is excavated using a rectangular clamshell bucket or other specialized equipment. During excavation, the trench is held open by introduction of a bentonite or polymer slurry. Steel reinforcement, if required, is lowered into the slurry-filled trench, and concrete is subsequently deposited by tremie, displacing the slurry. The length of trench open at any one time is limited to a typical maximum of about 20 to 24 feet by excavation stability and concrete placement volume considerations. Each individual concrete placement is referred to as a “panel,” and vertical construction joints separate the panels. Temporary “end-stops” are used as formwork to control the geometry of the panel joints, and horizontal reinforcement is discontinuous at the joints. Structural slurry panels range from 1.5 to 5.0 feet thick, 7 to 24 feet long, and up to 300 feet deep. In the United States, panels that are 2.0 to 3.5 feet thick and depths of 40 to 150 feet are commonplace. Structural basement walls support earth pressures acting laterally against the wall, dead and live loads acting vertically, and in-plane shear and flexure from wind and earthquake loads. The design of permanent slurry walls in regions of low or moderate seismicity is often limited to providing the strength necessary to resist out-of-plane soil pressures and vertical dead and live loads from the superstructure and basement framing. Although these walls also transfer in-plane lateral forces from the superstructure into the soils, the walls are often not specifically designed for these in-plane forces because their inherent strength is usually much greater than the forces being transferred. If resistance to in-plane forces acting on a wall required an increase in vertical reinforcement at the ends of a wall segment, an increase in the cap beam strength, or an increase in the horizontal reinforcement for shear strength, the overall design and construction approach would not vary significantly from current practice. Structural slurry walls have been used to a limited extent for buildings designed for high seismic risk, but there is reluctance on the part of design engineers to use them more often because of concern for how to design these walls to resist in-plane lateral forces, lack of code provisions for reinforcement detailing, and damage that may occur at panel joints. For buildings designed for high seismic risk, such as those assigned to Seismic Design Categories (SDC) D, E, and F as defined in Minimum Design Loads for Buildings and Other Structures (ASCE/SEI 7-10), in-plane shear and flexural actions may likely require modifications of a structural slurry wall only designed for out-of-plane soil pressures and vertical live and dead loads. Design would need to address in-plane lateral forces acting on structural slurry walls and the interaction of the in-plane actions with the out-of-plane and vertical actions. These issues are discussed in this report, and approaches to design for high seismic risk are presented.

United States Department of Agriculture, May 1995. http://dx.doi.org/10.32747/1995.7613021.bard.

Full text
Abstract:
Our previous work indicated that suspension-cultured plant cells show remarkable flexibility in altering cell wall structure in response either to growth on saline medium or in the presence of the cellulose synthesis inhibitor 2,-6-dichlorobenzonitrile (DCB). We have continued to analyze the structure of these modified cell walls to understand how the changes modify wall strength, porosity, and ability to expand. The major load-bearing network in the walls of DCB-adapted dicot cells that lack a substantial cellulose-xyloglucan network is comprised of Ca2+-bridged pectates; these cells also have an unusual and abundant soluble pectic fraction. By contrast, DCB-adapted barley, a graminaceous monocot achieves extra wall strength by enhanced cross-linking of its non-cellulosic polysaccharide network via phenolic residues. Our results have also shed new light on normal wall stucture: 1) the cellulose-xyloglucan network may be independent of other wall networks in dicot primary walls and accounts for about 70% of the total wall strength; 2) the pectic network in dicot walls is the primary determinant of wall porosity; 3) both wall strength and porosity in graminaceous monocot primary walls is greatly influenced by the degree of phenolic cross-linking between non-cellulosic polysaccharides; and 4) the fact that the monocot cells do not secrete excess glucuronoarabinoxylan and mixed-linked glucan in response to growth on DCB, suggests that these two non-cellulosic polymers do not normally interact with cellulose in a manner similar to xyloglucan. We also attempted to understand the factors which limit cell expansion during growth of cells in saline medium. Analyses of hydrolytic enzyme activities suggest that xyloglucan metabolism is not repressed during growth on NaCl. Unlike non-adapted cells, salt-adapted cells were found to lack pectin methyl esterase, but it is not clear how this difference could relate to alterations in wall expansibility. Salt-adaped cell walls contain reduced hyp and secrete two unique PRPP-related proteins suggesting that high NaCl inhibits the cross-linking of these proteins into the walls, a finding that might relate to their altered expansibility.

While A-Walls are commonly constructed using micropiles, they can be constructed using any type of deep foundation element. For example, Gómez, et al. ( 2013) described the use of a large A-Wall for mitigation of lateral movements of the North Plaza of the Jefferson Memorial in Washington, D.C. The lateral movements accompanied settlement of the edge of the fill under the North Plaza and had caused significant disturbance to the original seawall. The A-Wall consisted of drilled shafts and driven piles extending to depths greater than 100 ft and connected through the new, replacement reinforced concrete seawall, as depicted in Figure 1. A-Walls have been successfully used for slope stabilization using schemes similar to that shown in Figure 2 (Gómez et al., 2013). Loehr and Brown (2008) describe a method for predicting resisting forces in A-Walls for slope stabilization based on measurements from full-scale field installations of A-Walls and physical model tests involving scaled micropile elements. The method was a significant development because it appropriately accounts for the complex interaction between deep foundations and moving soils. Although the method satisfies displacement compatibility, it does so with uncoupled analyses involving separate lateral and axial analyses, without consideration of interaction between upslope and downslope piles (which are connected through a capping beam). This assumption may produce errors in predictions of reinforcement forces, and could have a notable effect on the predicted performance of A-Wall systems. To evaluate the effect of coupling, the research team analyzed slopes stabilized with A-Walls using a finite element model with upslope and downslope piles connected at the pile head. Results of the finite element analyses were compared to those of uncoupled lateral and axial analyses utilizing the p-y and t-z methods. Load-transfer parameters for the analyses were calibrated to data from field installations of A-Walls to demonstrate viability of the revised methodology. Results of the coupled analyses were then compared to results from Loehr and Brown (2008) to evaluate the effect of interaction between upslope and downslope piles. This report includes design implications resulting from the coupling effect and recommendations for further research.
