Infrastructure for Open Access: Mechanics, Economics, Politics

Using the Pennsylvania State University Libraries as a case study, this essay explores the development of a library-based open access publishing program, and illustrates how open access library publishing can facilitate open access models by providing additional infrastructure for the dissemination of scholarly content

Impacts of Mobility Management and Human Service Transportation Coordination Efforts and End-User Quality of Life

This study developed an evaluation method to examine the effectiveness of mobility management and coordination programs in a community. A series of surveys were conducted of both transit users and stakeholders in communities across the country. Results from these surveys suggest improvements have occurred in efficiencies, ease of access, and quality of service. Most respondents to the stakeholder survey reported benefits that have been realized. Results from an ordered probit model demonstrate the positive impacts that improved mobility has on life satisfaction

An In Vitro Comparative Study of Intracanal Fluid Motion and Wall Shear Stress Induced by Ultrasonic and Polymer Rotary Finishing Files in a Simulated Root Canal Model

Objective. This in vitro study compared the flow pattern and shear stress of an irrigant induced by ultrasonic and polymer rotary finishing file activation in an acrylic root canal model. Flow visualization analysis was performed using an acrylic canal filled with a mixture of distilled water and rheoscopic fluid. The ultrasonic and polymer rotary finishing file were separately tested in the canal and activated in a static position and in a cyclical axial motion (up and down). Particle movement in the fluid was captured using a high-speed digital camera and DaVis 7.1 software. The fluid shear stress analysis was performed using hot film anemometry. A hot-wire was placed in an acrylic root canal and the canal was filled with distilled water. The ultrasonic and polymer rotary finishing files were separately tested in a static position and in a cyclical axial motion. Positive needle irrigation was also tested separately for fluid shear stress. The induced wall shear stress was measured using LabVIEW 8.0 software

Dissemination as cultivation: scholarly communications in a digital age

Participatory web platforms have greatly enhanced the means by which students, scholars, and practitioners engage in arts and humanities research. Intuitive interfaces and content delivery systems have brought about paradigm shifts in the ways in which scholars connect and communicate, removing the need for advanced technical expertise when conducting a range of scholarly activities. Collaborative networks of both research and communications are now facilitated across ubiquitous systems that interact to form a transdisciplinary and dynamic interconnection of thought and practice. This chapter introduces readers to the underlying principles of scholarly communications and publishing in the digital age, uncovering the affordances and limitations of online public scholarship. The relationship between form and content is discussed, drawing upon relevant case studies to demonstrate how scholars should consider cultivating the habits and practices of thick collegiality. From here, an overview of relevant platforms is offered, before strategies for social media are detailed, all of which are supplemented by this chapter’s corresponding electronic materials

Tetraquarks in a chiral constituent quark model

We analyze the possibility of heavy-light tetraquark bound states by means of a chiral constituent quark model. The study is done in a variational approach. Special attention is paid to the contribution given by the different terms of the interacting potential and also to the role played by the different color channels. We find a stable state for both $qq\bar{c}\bar{c}$ and $qq\bar{b}\bar{b}$ configurations. Possible decay modes of these structures are analyzed.Comment: 13 pages, no figures.

System for and method of performing evaluation techniques on a log or round timber

A system for and method of evaluating a log. The system includes an analysis module having at least one input terminal connectable to the at least one input device. The at least one input terminal is operable to receive at least one signal representing at least one measured property of the log and at least one determined parameter of the log determined in response to an energy being applied to the log. The analysis module further includes a processor coupled to the at least one input terminal. The processor determines a predictive modulus of elasticity (MOE) of the log based at least in part on the at least one measured property and the at least one sensed parameter. The analysis module also includes an output terminal coupled to the processor and connectable to an output device. The output terminal transmits a third signal representing the predictive MOE.https://digitalcommons.mtu.edu/patents/1042/thumbnail.jp
