Multi-touch app development with modern web tools

Presentation at Statewide IT 2015 ConferenceThe use of familiar web technologies makes it easier to enable multi-touch experiences from anywhere with a web browser and a touchscreen, from phones to desktops to large touch tables and display walls. This presentation will take you through the UITS Advanced Visualization Lab's workflow, which uses modern web development tools to create multi-touch applications

Mycobacterial panniculitis caused by Mycobacterium thermoresistibile in a cat.

Case summaryA domestic shorthair cat was evaluated for chronic, bilateral, ulcerative dermatitis affecting the inguinal region and lateral aspects of both pelvic limbs. Histopathologic examination of skin biopsies collected throughout the course of disease revealed chronic pyogranulomatous ulcerative dermatitis. Aerobic bacterial skin cultures yielded growth of a methicillin-resistant Staphylococcus aureus and Corynebacterium amycolatum. Upon referral the clinical findings were suggestive of a non-tuberculous Mycobacterium species infection. Previously obtained skin cultures failed to yield growth of mycobacterial organisms. A deep skin biopsy was collected and submitted for mycobacterial culture. At 5 weeks of incubation Mycobacterium thermoresistibile was isolated. In previous reports, M thermoresistibile has been isolated after 2-4 days of incubation, suggesting that this strain may have been a slower growing variant, or other factors (such as prior antimicrobial therapy) inhibited rapid growth of this isolate. The cat was hospitalized for intravenous antibiotic therapy, surgical debridement of wounds, vacuum-assisted wound closure therapy and reconstruction procedures. The wounds were ultimately primarily closed and the cat was discharged to the owner after 50 days of hospitalization. Seven months after hospitalization, the ulcerative skin lesions had healed.Relevance and novel informationTo our knowledge, only two cases of M thermoresistibile panniculitis have been reported in cats. In the only detailed report of feline M thermoresistibile panniculitis, treatment was not attempted. The second case only reported detection of M thermoresistibile by PCR without a clinical description of the case. In our case report, severe chronic skin infection with M thermoresistibile was addressed using prolonged specific antibiotic therapy, surgical debridement and reconstructions, and treatment of secondary bacterial infections

Development of Thermoplastic Composite Reinforced Ultra-High Performance Concrete Panels for Impact Resistance

Recent studies investigating the impact performance of ultra-high performance concrete (UHPC) reported a quasi-brittle flexural failure that transitioned to a brittle punching-shear failure as the size of the impact head was reduced. A potential technology to increase the flexural strength and impact resistance of concrete is applying fiber reinforced polymer (FRP) composites to the exterior faces of the beam or slab. In this work, E-glass fiber reinforced thermoplastics were utilized in two different systems to apply reinforcement to UHPC. Thermoplastic materials were chosen over traditional thermoset materials for their unique advantages, such as rapid fabrication, automated manufacturing and the ability to weld to the material. These advantages could create an ideal system for large scale production of UHPC panels with thermoplastic reinforcement for use in protective systems. The two systems investigated were stamped thermoforming and vacuum infusion. For stamped thermoforming, the UHPC, fiber reinforced prepreg tapes and an additional layer of thermoplastic resin were heated then consolidated. Upon cooling the multiple prepreg layers of thermoplastic tapes were formed into a complete laminate, which was completely bonded to the UHPC core. The second system to reinforce the UHPC was vacuum infusion using a two-part liquid thermoplastic resin-system and a woven roving fabric. The impact performance of the thermoplastic composite reinforced UHPC panels was characterized using a combination of drop-weight impact testing and quasi-static testing. After testing it was confirmed that the application of thermoplastic composite skins to UHPC panels improved the impact resistance of the UHPC. Preliminary results showed little or no performance differences between the thermoplastic tapes and the vacuum infused panels. Thermoplastic tape reinforcement may have a fabrication method well suited for automated production, which is an advantage over the labor intensive vacuum infusion procedure. More work must be performed in order to optimize the thermoplastic composite reinforced UHPC panel design for impact resistance
