    Fabric Study and Structural History of Deformed Plutonic and Metamorphic Rocks in the Holden Area, North Cascades, Washington

    The Holden area, in the Crystalline Core of the North Cascades, contains deformed and undeformed plutons ranging from Triassic to Eocene in age. Two deformational styles have been identified in the Holden area. Contractional deformation is indicated by steeply-plunging, down-dip, mineral and stretching lineations in the syn-tectonic Seven Fingered Jack pluton (estimated midLate Cretaceous), and in the pre-tectonic Dumbell Mountain pluton (220 Ma), associated with apparent flattened fabrics. Strike-slip shear deformation is represented by gently-plunging to subhorizontal, strike-parallel mineral and stretching lineations, which are commonly associated with constricted fabrics. These fabrics occur prominently in the Dumbell Mountain pluton, and crosscut successive intrusive phases in the syn-tectonic root of the Duncan Hill pluton (47-45 Ma emplacement age). Thus, contractional and strike-slip styles of deformation may have been active from mid-Late Cretaceous to early Tertiary in the Holden area. Deformation of uncertain style was active in the mid-Late Cretaceous in the Cardinal Peale pluton (73 Ma), evidenced by: 1) an elongate map pattern; 2) xenoliths aligned parallel to pluton contacts; and 3) a northwest striking foliation defined by recrystallized textures, all of which are aligned parallel to the foliation in the country rock. Metamorphism reached the amphibolite facies in the Holden area as indicated by the assemblage hornblende + oligoclase + garnet. A few chlorite + albite + epidote assemblages and local alteration of biotite, hornblende, and garnet to chlorite reflect overprinting by a pervasive low-grade metamorphic event. Steeply-plunging lineation and strike-parallel lineation are defined by amphibolite facies assemblages, indicating that medium-to high-grade metamorphism was coeval with deformation. Strike-parallel lineations defined by both ductile and brittle fabrics with associated chlorite are probably related to deformation associated with later low-grade metamorphic conditions. Existing models for the structural development of the Cascades include a collisional model resulting in essentially SW-NE directed contraction (Brandon and Cowan, 1985), and a strike-slip or transpressional model resulting in NW-SE lineations with low plunge (Brown and Talbot, 1989). Data for the Holden and surrounding areas indicates that both contraction and strike-slip shear deformation were active at the same time. It is possible that oblique convergence from 80 Ma to 43 Ma was partitioned into orogen-normal and orogen-parallel components to produce coeval contractional and strike-slip shear structures. The development of two structural styles in the Holden area emphasizes the need to incorporate both strike-slip and contractional processes as important deformation mechanisms in the orogenesis of the Crystalline Core of the North Cascades

    Evaluation of pigmented post-consumer recycled polyethylene properties

    With increased regulation of recycled materials, such as minimum content claims for bags and rigid containers in California, additional research was needed to understand how the recycled content affects the material properties and safety of these polymers. The objective of this research was to investigate how material properties changed as commodity recycled material is incorporated into commercial products, and if these changes can be modeled. Post-consumer recycled (PCR) linear low-density polyethylene (LLDPE) feedstocks were blended with virgin LLDPE to create 0, 20, 40, 60, 80, and 100% wt/wt PCR sample sets. The recycled feedstocks contained either exclusively calcium carbonate or a blend of calcium carbonate and carbon black pigments. The sample blends were extruded on a Wayne single screw extruder into film and sheet. Samples were evaluated using thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), ultraviolet-visible (UV-Vis) and fluorescence spectroscopy. Extractions in nhexane and xylene were performed according to Code of Federal Regulations (CFR) Title 21, B, Part 177.1520 for regulatory compliance with direct food contact applications. Results of this study suggest the potential for modeling of recycled content in pigmented polyethylene, particularly using ultraviolet spectroscopy, and that post-consumer recycled material may be safely incorporated into food contact applications

    Dervish Sound Dress; An Investigation of Wearable Technology Using Computer Music and Haptic Mechanisms for Live Performance

    Get PDF
    The realm of this thesis combines the areas of computer music, fashion design, digital art, smart clothing, biometrics, cultural traditions and performance. Dervish Sound Dress is a wearable piece of technology; a garment that is inspired by the sacred ‘turning’ experience of the Whirling Dervishes or the Mevlevi Sufi order in Turkey known as the sema. It utilizes the fundamental aspects of the sema such as music, performance and body movement through spiritual elation by creating a unique and interactive experience. Wearable technology is a burgeoning field of research. Fashion designers who are using smart textiles or integrating fashion and technology in some way require collaboration with electrical engineers and programming professionals. The garment functions as a body instrument and can be manipulated by the wearer. The cultural traditions of the Mevlevi Sufis and their metaphysical experience during the turning ritual of the sema performance is the inspiration behind the creation of a garment that emulates sounds by using body movement. Dervish Sound Dress is outfitted with sensors that trigger musical sounds when the wearer touches the bodice interface or changes gesture or movement. The wearer is alerted to the sounds through the use of haptics that are sensed on the body. The sensation is similar to when a musician plays an instrument that reverberates resulting in an immersive relationship that goes further than the auditory. The aim is to develop garments that will inspire the creation of musical sounds that can be controlled by an intuitive interface in clothing. It is a study that uses technology and performance by taking a sacred experience and creating artistic expression. Dervish Sound Dress seeks to examine how technology can be integrated into a garment as an expressive body instrument to augment contemporary sonic performance
