Exploration of 3D printing to create zero‑waste sustainable fashion notions and jewelry
Anupama Pasricha,Rachel Greeninger 한국의류학회 2018 Fashion and Textiles Vol.5 No.1
This research followed design as a research paradigm to apply zero-waste principles to 3D printing in efforts to ensure sustainable applications of 3D technology in the apparel and fashion industry. Researchers used Rhinoceros 5, Tinkercad, MakerBot Replicator 2 desktop 3D printer, and polylactic acid filament to create elaborate designs. This design research is the first successful attempt at 3D printing for biodegradable zero-waste fashion notions and accessories. The researcher employed design thinking and strategies to create objects without the use of rafts and supporters removing waste creation. Multiple attempts resulted in an acceptable outcome of five pendant designs for necklaces, two earring designs, and nine layer-designed buttons. The buttons were attached to a draped cape design utilizing 95% of the fabric. There is a considerable potential to use this disruptive technology in designing and creating fashions that are unique, sustainable (zero-waste), and made on demand.
Adaptive Scratch Pad Memory Management for Dynamic Behavior of Multimedia Applications

<P>Exploiting runtime memory access traces can be a complementary approach to compiler optimizations for the energy reduction in memory hierarchy. This is particularly important for emerging multimedia applications since they usually have input-sensitive runtime behavior which results in dynamic and/or irregular memory access patterns. These types of applications are normally hard to optimize by static compiler optimizations. The reason is that their behavior stays unknown until runtime and may even change during computation. To tackle this problem, we propose an integrated approach of software [compiler and operating system (OS)] and hardware (data access record table) techniques to exploit data reusability of multimedia applications in Multiprocessor Systems on Chip. Guided by compiler analysis for generating scratch pad data layouts and hardware components for tracking dynamic memory accesses, the scratch pad data layout adapts to an input data pattern with the help of a runtime scratch pad memory manager incorporated in the OS. The runtime data placement strategy presented in this paper provides efficient scratch pad utilization for the dynamic applications. The goal is to minimize the amount of accesses to the main memory over the entire runtime of the system, which leads to a reduction in the energy consumption of the system. Our experimental results show that our approach is able to significantly improve the energy consumption of multimedia applications with dynamic memory access behavior over an existing compiler technique and an alternative hardware technique.</P>
Review : Recent Advances in the Pathophysiology and Treatment of Gastroparesis
( Jung Hwan Oh ),( Pankaj J Pasricha ) 대한소화기기능성질환·운동학회(구 대한소화관운동학회) 2013 Journal of Neurogastroenterology and Motility (JNM Vol.19 No.1
Gastroparesis is a clinical disorder characterized by upper gastrointestinal symptoms related with delayed gastric emptying of solids and liquids in the absence of mechanical obstruction. Diabetes mellitus has been the most common cause of gastroparesis and idiopathic gastroparesis also accounts for a third of all chronic cases. The most important mechanisms of gastroparesis, as understood to date, are loss of expression of neuronal nitric oxide synthase and loss of the interstitial cells of Cajal. However, the pathogenesis of gastroparesis is poorly understood. There have been several studies on specific molecules related to the pathogenesis of gastroparesis. Additionally, the Gastroparesis Clinical Research Consortium of the National Institutes of Health has achieved several promising results regarding the pathophysiology of gastroparesis. As the progress in the pathophysiology of gastroparesis has been made, a promising new drug therapy has been found. The pathophysiology and drug therapy of gastroparesis are focused in this review. Until now, the real-world medication options for treatment of gastroparesis are limited. However, it is expected to be substantially improved as the pathophysiology of gastroparesis is elucidated.

Surgical excision along with use of postoperative radiotherapy forms an integral management of sinonasal teratocarcinosarcoma (SNTCS). However, given the rarity of the tumor, no standardised guidelines, dose, technique and target delineation exist especially in the era of modern radiation delivery techniques. This is a case of 55-year-old male diagnosed as SNTCS treated with radical ethmoidectomy followed by volumetric modulated radiotherapy, showing good local control and acceptable toxicity profile.

Organisation of nanoparticles on structurally well-dened templates is a rst step towards creating nanomachines. In this respect,nucleic acids are ideal structural templates and a variety of secondary structures realizable from DNA/RNAe.g., duplexes, hair-pins, triplexes, cruciforms, tetraplexes can be exploited to engineer nanoparticle organization at will. We have used oligonucleotidesand their analogues such as phosphorothioates and peptide nucleic acids to electrostatically encapsulate cationic-capped gold na-noparticles. This article describes synthesis and characterization of DNA/PNA-gold nanoparticle composites using TEMandUV-Tm techniques. These types of assemblies may have potential for creating nanowires and lithographic circuits.. 2004 Elsevier B.V. All rights reserved.
