SPLAT: Innovative Collaboration in Idaho's Libraries  [cached]
Memo Cordova,Amy Vecchione
Journal of Library Innovation , 2011,
Abstract: Libraries face shrinking budgets, increased use, and user demand for trendy resources. This makes it difficult for librarians to find the time to keep current with innovative library trends, such as technological tools and social media developments. The Special Projects Library Action Team (SPLAT) offers a new model for enhancing library services. SPLAT is a group supported by the Idaho Commission for Libraries (ICFL), the state agency responsible for assisting libraries. The members of SPLAT are innovation representatives who search and experiment with social media trends and online tools, and share the best ways to integrate them into services at all types of libraries. SPLAT members have developed SPLAT 101, an online class geared towards teaching library staff new Web technologies. Members also present about trends at conferences, blog relevant content, and engage in peer-to-peer education--all meant to demystify and exploit emergent technologies. These efforts have yielded enhanced library services, encouraged changes to policies, and increased positive user experiences. In this article we summarize how SPLAT works, explain how SPLAT has helped Idaho's libraries experiment with evolving services, analyze the success of SPLAT as a model for other states, and discuss future steps.
Ethylene Methacrylic Acid (EMAA) Single Splat Morphology  [PDF]
Wei Xie,James Wang,Christopher C. Berndt
Coatings , 2013, DOI: 10.3390/coatings3020082
Abstract: A single splat is the building block of a thermal spray coating; thus, investigating single splats is essential to understanding thermal spray coatings and their properties. In this study, the morphology of flame sprayed ethylene methacrylic acid (EMAA) splats, deposited at various stand-off distances (SODs) onto glass and mild steel substrates were investigated using a scanning electron microscope, Leica M Stereo-microscope, the WYKO surface profiler and the ContourGT surface profiler. This work analyzed the effect of the process variables on EMAA splat morphology. The modeling of the temperature versus velocity (TV) map, the temperature versus stand-off distance (TS) map and the velocity versus stand-off distance (VS) map of EMAA single splat were presented.

Journal of Achievements in Materials and Manufacturing Engineering , 2006,
Abstract: shorten the service lifetime of the spray coatings. It is therefore essential to investigate the evolution of thetemperature and the distribution of the residual stresses, which are primarily induced by initial temperaturedifference and thermal expansion coefficient mismatch between the splat and the substrate.Design/methodology/approach: As the plasma spraying process involves the solidification and cooling ofextremely tiny molten metal droplets in a very short time, it is very difficult to observe the procedure directly.In this paper, a finite element model involving the temperature and residual stress simulation of a singleNiCoCrAlY particle splat in plasma spraying when cooled on the carbon steel substrate is presented.Findings: The numerical analysis results show that the temperature rise is more evident within the interior than on thetop surface of the substrate. The maximum residual stresses of about 170 MPa appear at the central part of the splat.Research limitations/implications: Future work should integrate the flattening process with the solidificationand cooling of the droplet.Practical implications: It will be helpful to the understanding and control of residual stresses in plasma spraying.Originality/value: This research simulates the evolution temperature and residual stress distribution during thesolidification and cooling process on the single splat level in plasma spraying.

Physics , 2014, DOI: 10.1016/j.ascom.2014.06.001
Abstract: SPLAT-VO is a powerful graphical tool for displaying, comparing, modifying and analyzing astronomical spectra, as well as searching and retrieving spectra from services around the world using Virtual Observatory (VO) protocols and services. The development of SPLAT-VO started in 1999, as part of the Starlink StarJava initiative, sometime before that of the VO, so initial support for the VO was necessarily added once VO standards and services became available. Further developments were supported by the Joint Astronomy Centre, Hawaii until 2009. Since end of 2011 development of SPLAT-VO has been continued by the German Astrophysical Virtual Observatory, and the Astronomical Institute of the Academy of Sciences of the Czech Republic. From this time several new features have been added, including support for the latest VO protocols, along with new visualization and spectra storing capabilities. This paper presents the history of SPLAT-VO, it's capabilities, recent additions and future plans, as well as a discussion on the motivations and lessons learned up to now.

Journal of Materials , 2013, DOI: 10.1155/2013/260758
Abstract: Thermal spraying is a well-established surface modification technology which has been widely used in industrial applications. As the coating properties were mainly determined by the flattening nature of each splat, much attention has been increasingly paid to the study on the splat formation process of thermal sprayed particles. This paper is concerned with the development in the research of the splat formation process of the individual splat deposited by thermal spraying during the past few decades, including the experimental and numerical simulations up to today; some classical splashing models were also reviewed. As a simulation of the actual thermal spray process, the development of the flattening behavior of free falling droplet has been mentioned as well. On the basis of the current investigation, some recommendations for the future work have been advised. 1. Motivation to Study Splat Formation Process “God made the bulk; the surface was invented by the devil” [1]. This comment indicates that the surfaces of parts are the location for many phenomena between the material and its environment, where all physical and chemical interactions and exchanges take place [2]. As most of the material damage and failure start from the surface of the material, beside the so-called nanotechnology, surface modification technology has been quickly developed. This method is a hopeful way to realize the sustainable human society in future, as it enables both high performance and recyclability of the material, through modifying the surface of a material by bringing physical, chemical, or biological characteristics different from the ones originally found on the surface of a material, which have been attracting a great deal of attention from various industries, as they present a way to get an entirely different material performance from the surface of materials merely through surface engineering techniques [3]. In general, thermal spraying is such a typical process that can provide thick coating ranging from 20?μm to several millimeters on the substrate. This method has been developed since the early 1910 when Dr. Schoop introduced the technique with a flame as the heat source and molten lead for feedstock materials [4], while both electrical (plasma or arc) or chemical means (combustion flame) were usually used as the source of energy for thermal spraying nowadays. Using this technology, thick coatings can be deposited on the substrate over a large area at a high deposition rate as compared to other coating processes in a very short time; in addition, almost all kinds

Abstract: The most common hazards in the forestry that may induce disorders of the musculoskeletal system are vibrations, unfavorable microclimatic conditions, noise, over-time working hours, work load and long-term repeated movements. The objective of this study was to analyze the prevalence of musculoskeletal diseases and its difference among workers engaged in various jobs in the forestry. Two groups of workers were selected: woodcutters operating with chain-saw (N=33) and other loggers (N=32). Selected workers were of the similar age and had similar total length of employment as well as the length of service in the forestry. Both groups of workers employed in the forestry had the high prevalence of musculoskeletal diseases (woodcutters 69.7% and other loggers 62.5%, respectively). Degenerative diseases of spinal column were very frequent, in dependently of the type of activity in the forestry. Non-significantly higher risk of carpal tunnel syndrome was found in woodcutters with chain-saw compared to workers having other jobs in the forestry (OR=3.09; 95%CI=0.64-19.72). The lateral epicondylitis was found only in woodcutters operating with chain-saw with the prevalence of 18.2%.
