Measurement of thermal parameter and Reynolds number effects on cavitation instability onset in a turbopump inducer
Authors: Kim Junho , Song Seung Jin 
Published: August 2017

AbstractThis study experimentally examines how the non-dimensional thermal parameter and Reynolds number affect cavitation instability onset in a turbopump inducer using water. Based on the time-resolved static pressure measured at the inlet of the turbopump inducer, the onset cavitation number of rotating cavitation has been determined for varying Reynolds number and non-dimensional thermal parameter values. Increasing non-dimensional thermal parameter suppresses rotating cavitation and causes a monotonic decrease in the rotating cavitation onset cavitation number. At low non-dimensional thermal parameter values (e.g., 0.0125), the onset cavitation number is independent of the Reynolds number. However, at higher values of the non-dimensional thermal parameter (e.g., higher than 0.0537), the onset cavitation number increases with increasing Reynolds number. Thus, the Reynolds number promotes rotating cavitation onset. This study provides the first assessment of the independent effects of the non-dimensional thermal parameter and Reynolds number.

Background: The benefits of “spaced education” have been documented for residents in highly focused specialties. We found no published studies of spaced education in family medicine. In this study, we report on the feasibility of delivering weekly alerts from a mobile application (app) developed for exam preparation, to increase the reading of clinical information in the family medicine residency.
Methods
Design: This is a 2-phase mixed methods study. Phase one is a quasi-experimental study of resident reading of information related to priority topics in family medicine. Reading was documented by page views in a noncommercial mobile app.
Participants: All incoming first-year residents at two university training programs in Canada. The intervention group received one alert per week to priority topics on the app, beginning in their second month of residency. The control group was given access to the same app, but received no alerts.
Results: In this paper, we report the phase one preliminary findings. In the intervention group, 81 of 96 first year residents consented. At the control site, 79 of 85 residents consented. After 100 days, intervention group residents had viewed more pages of clinical information across all 99 priority topics (1,546 versus 900) and per topic (15.7 versus 9.1 pages, P &lt; 0.0003). On average, each increase of one visit to the app following a weekly alert was associated with an increase of 3.2 visits to pages of clinical information in the app.
Conclusion: A weekly alert delivered via mobile app shows promise with respect to reading in the family medicine residency.

The use of worksheets in Excel is one of the tools for learning in solving the mathematical problems. At generaly the solution of mathematical problem ussually is solved by the soft ware aplication, that sure used high level programming languages like FORTRAN, BASIC, C++, MATLAB, etc. However the use of worksheet in Excel rather more familiar than using the software aplication for the students. It is caused the students must be able to know how to write the code program that obtained product the listing program. One of the most problematic on civil engineering is about concrete beam structure deflection. The mathematical analysis simple beam structure deflection is presented by the ordinary differential equation second order non linier and the other name it’s called poisson equation. The aim of this article for : (1) To give the learning assistance to the student when they aren’t use the soft ware program and beside to rise creation the application spreadsheet as tool for numerical solution by finite difference method on simple beam deflection. (2) To evaluate the error result comparation of numeric solution and analytic solution.(3)To give the understanding about numerical method that accordance with simple beam deflection problem on civil engineering education and mathematical education.
