Sds Non-Acrylamide Polymeric Gel-Filled Capillary Electrophoresis For Molecular Size Separation Of Protein, Devon Andres Aug 1993

Sds Non-Acrylamide Polymeric Gel-Filled Capillary Electrophoresis For Molecular Size Separation Of Protein, Devon Andres

Honors Theses

Sodium dodecyl sulfide (SDS) non-acrylamide gel-filled capillary columns are a new technology being used for analysis and separation of biotechnology-derived proteins. This research was to compare this new technology to the current methods of SDS polyacrylamide gel electrophoresis (SDS-PAGE) and high-performance size-exclusion chromatography (HPSEC). The molecular mass of four different recombinant proteins were determined by two commercialized SDS non-acrylamide gel-filled capillary columns, SDS-PAGE, and HPSEC. The data obtained showed that the SDS non-acrylamide gel-filled capillary columns were compatible with the SDS-PAGE technique for molecular mass determination. HPSEC was shown to be unreliable for molecular weight determination. SDS non-acrylamide gel-filled capillary …


Design And Construction Of A Lithium Vapor Oven, Corey A. Leon Jul 1993

Design And Construction Of A Lithium Vapor Oven, Corey A. Leon

Honors Theses

A lithium vapor oven to be used as a source of lithium target atoms in atomic collision experiments was designed and constructed. The oven was installed in the beamline of the Van de Graaff accelerator at Western Michigan University. Test results indicated the oven produced a diffuse cloud of evaporated lithium instead of the intended concentrated jet spray. Recommendations concerning the design are made for future efforts.


Gravity Modeling Of A Patch Reef In Allegan County, Michigan, Mei Leng Wong Jun 1993

Gravity Modeling Of A Patch Reef In Allegan County, Michigan, Mei Leng Wong

Honors Theses

The study of the Diamond Springs oil field in Allegan County focuses on the use of gravity to delineate individual reef buildups. The Diamond Springs oil field is a small patch reef located in northern Allegan County, Michigan. The reef, which is approximately 1400 feet deep, is located within the Middle Devonian Traverse Limestone and was deposited in an open shelf, carbonate platform and lagoonal environment. The reef covers an area of approximately one square mile and has a vertical relief of 30 to 80 feet. These porous reef materials are commonly buried by muds or evaporites resulting in ideal …


The Investigation Of Object-Oriented Methodology As An Enabling Technique For End-User Application Development, Eng Chong Lim Apr 1993

The Investigation Of Object-Oriented Methodology As An Enabling Technique For End-User Application Development, Eng Chong Lim

Honors Theses

This research studies the value of object-oriented methods to design information systems that can then be developed and implemented by end-users.


The Extent Of Multimedia Computer Applications In The Business World, Mei Yee Lim Jan 1993

The Extent Of Multimedia Computer Applications In The Business World, Mei Yee Lim

Honors Theses

The world, or at least I, was all agog when touch screens arrived. My initial contact with touch screens was at a science exhibition in Menara MPPJ, Petaling Jaya, Malaysia in July 1987. That particular exhibit, which encouraged visitors to participate and to experiment with, was a graphic program. Visitors could use their fingers to select the drawing tool or the color they want (which is something like the tools on a MacDraw screen on a Macintosh) and use their fingers to move around the screen to draw anything they want. That added to my fascination with the world of …
