Defining Sustainability Through Bentwood Lamination
What does sustainability mean with respect to furniture design and fabrication? How has technology - created and subsequently clouded - opportunities for new thinking? This body of work explores these broader questions and, more specifically, the efficiencies of bending wood. Historical precedents …

Lamination of a biodegradable polymeric microchip
… two potential designs that are fabricated via lamination, and a final design was proposed based on the results. Design 1 sought to replace the sealant directly with a PLA backing layer, but the laminated backing layer was found to leak in 14C-dextran release experiments. Design 2 used a …

Study of steel mills lamination coils cooling
… Steel coil produced at a steel mill after the lamination must be cooled from a high temperature to the ambient temperature, to be transported and sold. Coil cooling takes between four and six days depending on weather conditions. Usually, the coil will be stored in a warehouse until it reaches …

Lamination of Inverted Organic Photovoltaics and Associated Physical Properties
… of a series of studies involving hot press lamination of inverted organic photovoltaics. It first gives background and develops a lamination process for fabrication. Then, the process is used to answer fundamental questions about organic photovoltaics and to fabricate previously impossible …

Variations in low-grade wood modification and stress lamination
… is incompatible with standards for glue-based lamination. Alongside this forecasted increase, there is a major worldwide shift towards building taller and faster with massive laminated and engineered wood products, mainly as substitutes for steel and concrete. For making the best use of the …

Multidisciplinary Design Optimization of Composite Spacecraft Structures using Lamination Parameters and Integer Programming
… optimization techniques developed in this work. Lamination parameters and MIP are adopted to optimize composite panels efficiently. The framework integrates structural, thermal and acoustic analysis to optimize the spacecraft's overall performance while satisfying multiple design constraints. Its …

Characterization of anisotropy in organic-rich shales: shear and tensile failure, wave velocity, matrix and fracture permeability
Lamination and fractures are common features in organic-rich shales. The objective of this thesis is to determine the impact of lamination and fractures on elastic properties, shear and tensile failures, and the permeability of organic-rich shales. The elastic properties of rocks determine the …

Integration of Numerical Simulation and Wireline Formation Testing Measurements for Permeability Interpretation
… it is extremely difficult to detect such a lamination by running the conventional openhole logs because of their insufficient vertical resolution. Therefore, it is of fundamental and practical importance to quantify the effective formation thickness in thick formation and determine the …

Morphogenesis of the lateral geniculate nucleus in primates
… macaque monkey, the LGN exhibits an intricate lamination pattern, which changes midway through the nucleus at a point coincident with small gaps due to the blind spot in the retina. This thesis investigates the hypothesis that the singularities produced by the gaps induce the laminar transition …

CHEMICAL AND PHYSICAL ANALYSIS OF LAMINATED SEDIMENT FORMED IN LOE POOL, CORNWALL
… are found in Loe Pool. The origins of such laminations are investigated and evidence for their conditions of formation are presented. In all sediment analysed the combustion residue was greater than 80%, and in the black and grey annually-laminated sediment the organic matter was less than …

Laminated Sediments of Loch Ness, Scotland: Indicators of Holocene Environmental Change
… composed of irregular sequences of pale and dark laminations, most sub-millimeter in thickness, some ca 5 mm thick. Enumeration of laminae, and determination of lamination thickness, was carried out using X-radiography and image analysis. A hypothesis was developed that the finer laminations …

Use of Material Tailoring to Improve Axial Load Capacity of Elliptical Composite Cylinders
… through the use of a circumferentially-varying lamination sequence. The concept of varying the lamination sequence around the circumference is considered as a viable approach for off-setting the disadvantages of having the cylinder radius of curvature vary with circumferential position, the …

Gromov boundaries of complexes associated to surfaces
… one arc or curve with a geodesic asymptotic to a lamination or a leaf of the lamination. Using these paths, we give new proofs of the results of Klarreich and Schleimer identifying the Gromov boundaries of the curve graph and the arc graph, respectively, as spaces of laminations.

Secondary Buckling of Laminated Composite Plates
… to variations in boundary conditions, lamination sequence, imperfections, and stiffener geometry has been considered. It has been found that the occurrence of secondary buckling in clamped-simply supported plates under uniform end shortening critically depends on the intensity of …

Finishing Processes for Zein Biodegradable Films
Lamination and coating processes of zein-oleic acid films provided films with range of tensile properties, gas barrier properties, and thermal properties. The range could make zein-based films potentially useful in packaging applications for fresh produce of different respiration rates.

Statistical control and experimental design for edge bead reduction in laminating process
… well-known phenomenon typically happening in the lamination due to the physics of this process. It causes the defect of high edge observed in the carton roll after the laminated carton sheets are wrapped around the roller in Company X; the affected carton sheets can no longer be fed into …

Condition monitoring of pharmaceutical powder compression during tabletting using acoustic emission
… pharmaceutical tablets and detection capping and lamination during powder compression process using the acoustic emission (AE) method. Pharmaceutical tablet manufacturers obliged by regulatory bodies to test the tablet's physical properties such as hardness, dissolution and disintegration before …
