Effect Of Size Reduction Parameters In Pharmaceutical Manufacturing Process, Brian Breneman Dec 2011

Effect Of Size Reduction Parameters In Pharmaceutical Manufacturing Process, Brian Breneman

Biomedical Engineering

Within pharmaceutical manufacturing, size reduction is one of the most extensively used and vital unit operations. Size reduction in tablet production is achieved primarily through milling procedures, which allows for attaining product uniformity, optimizing product solubility, and improving bioavailability. Additionally, powders with a narrow range of size distribution can obviate problems in downstream processing as pertains to blending, compression, and coating as well as improve drug performance1. The purpose this study was to characterize the effect of various size reduction parameters as a result of the pharmaceutical milling process on a lactose wet granulation formulation and chemically active …


Improved Manufacturing Methods Of Bovine Femur Samples For Ultrasonic Testing And Assessment Of Materials Through Contract Angle Measurement, Kevin Mathew Lopez Galang Sep 2011

Improved Manufacturing Methods Of Bovine Femur Samples For Ultrasonic Testing And Assessment Of Materials Through Contract Angle Measurement, Kevin Mathew Lopez Galang

Biomedical Engineering

At California Polytechnic State University of San Luis Obispo (Cal Poly), the Biomedical Engineering department (BMED) requires its students to take the course listed as “BMED 420: Principles of Biomaterial Designs.” BMED 420 has a required laboratory section every week throughout the duration of the course that is meant to be a supplemental tool for learning. During the lab sections, students perform experiments and exercises that are currently being implemented in the industry. Despite accuracy of the methods and experiments relative to their use in the industry, there is always room for improvement. The objective of this project will illustrate …

An Inexpensive Method For Creating Paste To Be Used In Paper-Based Microfluidic Devices, Kirra Marie Sankey Jun 2011

An Inexpensive Method For Creating Paste To Be Used In Paper-Based Microfluidic Devices, Kirra Marie Sankey

Biomedical Engineering

Microfluidic devices are diagnostic tools that are small, portable, and inexpensive. This makes them ideally suited for resource-limited settings. To construct a 3D device, each layer of patterned paper is stacked using double-sided tape with holes corresponding to the pattern. It is necessary to have a paste to fill the holes in the tape and provide a medium for the fluid to wick through. The powder used to make the paste is very expensive and must be bought in bulk (an estimated $1121 - $1231), so it is not convenient for the Biomedical (BMED) department to use. This project was …

Investigation Of Pmma Cement Penetration In Prepared Femoral Heads With A Longitudinal Slot For Hip Resurfacing Arthroplasty, Scott Snyder Feb 2011

Investigation Of Pmma Cement Penetration In Prepared Femoral Heads With A Longitudinal Slot For Hip Resurfacing Arthroplasty, Scott Snyder

Biomedical Engineering

Hip resurfacing arthroplasty is becoming increasingly popular in younger, active patients due to its preservation of natural biomechanics. Failure of these implants can be very traumatic and potentially life threatening. The role of cement penetration in early implant failure is not yet known, and must be investigated. This study specifically investigates the effects of a 5mm by 5mm longitudinal channel on cement penetration into the femoral head. High-density open-cell reticulated vitreous carbon foam cylinders and Huntsman Pro-cast® 20 implants based on the Birmingham Hip Resurfacing implant were used. It was determined cement penetration was increased in the area immediately surrounding …
