Simplified computer program for the analysis of phase change in liquid face seals

A simplified computer program is presented which allows for the prediction of boiling (phase change) in liquid face seals. The program determines if and when boiling occurs and then calculates the location of the boiling interface, pressure and temperature profiles, and load. The main assumption which allows for a simplified analysis is the assumption of an isothermal gas phase

Big Read: Collaborations Between a University and a Community

University and community partners write about their collaborations around the reading of Ernest Gaines’ A Lesson Before Dying. When an urban university received a National Endowment of the Arts Big Read Grant, they immediately began making connections to existing key initiatives within the university and in the surrounding community. As the partners collaborated within and among the university and community programs and events created for the Big Read they made multiple discoveries regarding the importance of planning together, analyzing the intended audience for each program and event, including multiple ways to access the text, and considering the ways that readers can personalize the issues, synthesize what they have learned and apply it in discussion or action

Case study: A GPR survey on a morainic lake in northern Italy for bathymetry, water volume and sediment characterization

We carried out an extensive waterborne GPR survey consisting of 50 profiles with a total length of nearly 37 km on the morainic lake of Candia northerly Turin (Italy). Our aim was to test the capability of GPR to estimate the bathymetry, the water volume and the sediment type. We enhanced and controlled the GPR data processing and interpretation with bathymetry acquired with an acoustic echo sounder and measured conductivity and temperature profile of the water column with a multiparametric probe. We also analyzed the diffraction hyperbola that originated within the sediments in order to estimate the velocity and relative permittivity. With the permittivity and dielectric mixing rules, we estimated the porosity of the sediments above the diffracting objects and drew a map of the bottom lake porosit
