Selective Laser Melting of Biocompatible Metals for Rapid Manufacturing of Medical Parts

In recent years, digitizing and automation have gained an important place in fabrication of medical parts. Rapid Manufacturing could be very suitable for medical applications due to their complex geometry, low volume and strong individualization. The presented study investigates the possibility to produce medical or dental parts by Selective Laser Melting (SLM). The SLMprocess is optimized and fully characterized for two biocompatible metal alloys: TiAl6V4 and CoCrMo. This paper reports on mechanical and chemical properties and discusses geometrical feasibility including accuracy and surface roughness. The potential of SLM as medical manufacturing technique is proved by a developed procedure to fabricate frameworks for complex dental prostheses.Mechanical Engineerin

Censorship by Crying Wolf: Misclassifying Student Speech as Threats

Freedom of expression is at risk at colleges and universities across the country. While campus administrators employ a number of strategies to censor speech they disfavor, this piece explores the trend of justifying censorship and punishment of expression by labeling it a “threat” and citing concerns about safety. In contrast to the kind of speech the Supreme Court has defined as a “true threat,” the expression at issue in the cases discussed here poses no safety risk, comprising political commentary, jokes, and pop culture references. Its punishment both trivializes actual dangers and chills campus discourse. Accordingly, it is imperative that students, professors, and free speech advocates work to re- verse this trend and ensure institutions’ adherence to longstanding free speech principles

Coupling Benefits: Strategies for Vacant Land Reuse along Cleveland\u27s Opportunity Corridor

This paper discusses large scale planning efforts pertaining to vacant land reuse, economic development, and public participation along the Opportunity Corridor project in Cleveland, Ohio. The Corridor is a $331 million roadway project that will span 3.3 miles through some of Cleveland’s most blighted neighborhoods. Issues of distributional justice including underperforming public education, poor public health indicators, high rates of vacancy, and aging infrastructure contribute to neighborhood blight throughout the area. Stormwater management, access to multi-modal transportation, brownfield mitigation, and economic development are also prevalent issues throughout the project area. Advocacy work by the Kent State University Cleveland Urban Design Collaborative (CUDC) seeks to integrate planning efforts between multiple jurisdictions, civic actors, and community desires surrounding the project. This paper describes the community planning process in Cleveland surrounding the Corridor project, emphasizing the CUDC’s role in advocacy for an integrated planning approach to meet community needs

S.P.A.R.C.S.- Solar Panel Acoustic Resonance Cleaning System

As the world races towards the future of clean energy, solar panels are becoming common place. One of the largest problems faced is accumulated dirt and dust on the surface of these solar panels. Panels become covered in dirt and debris and no longer provide efficient output of solar energy. This problem is faced on earth and beyond the stars. For years, NASA has been trying to solve the issue of “dust” from mars or the moon settling on solar panels, lenses, and other surfaces. The regolith threatens the potential of human existence on the surface of the moon. The sharp edges are far more abrasive to human lungs if the particles are tracked in on equipment, suits, or shoes. As we extend our lunar exploration and attempt to establish a base on the moon, regolith removal will be key for human safety. Rover life spans have exceeded initial expectations, but nearly all face the same downfall. Their panels accumulate too much regolith for the solar rays to charge the rover.https://scholarworks.moreheadstate.edu/celebration_posters_2023/1032/thumbnail.jp

Disability and Citizenship in the Life and Fiction of Jean Little

Jean Little was one of the first children's authors to deal extensively with issues of disability. Her views towards disability were affected by her own experience of visual impairment, but also by her family's missionary work abroad and their commitment to social justice at home. While disability historians have often stressed the development of the "social model" of disability as being key to the creation of a disability rights movement, this paper suggests that disabled activism also had much to do with Canada's emerging self-definition as a place that stressed the importance of good citizenship, equality and inclusion. Jean Little a été une des premières auteures pour enfants à traiter abondamment de questions liées aux handicaps. Ses opinions à ce sujet ont certes été influencées par sa propre déficience visuelle, mais aussi par le travail missionnaire de sa famille à l'étranger et l'engagement de celle-ci envers la justice sociale au pays. Les historiens du handicap ont souvent mis l'accent sur la conception du > de handicap comme élément fondateur du mouvement pour les droits des personnes handicapées, or le présent article suggère que l'activisme handicapé a aussi eu beaucoup à voir avec l'émergence de la notion canadienne de pays qui défend le civisme, l'égalité et l'inclusion
