Biofilms: Formation, Research Models, Potential Targets, And Methods For Prevention And Treatment, Yajuan Su, Jaime T. Yrastorza, Mitchell Matis, Jenna Cusick, Siwei Zhao, Guangshun Wang, Jingwei Xie

Department of Mechanical and Materials Engineering: Faculty Publications

Due to the continuous rise in biofilm-related infections, biofilms seriously threaten human health. The formation of biofilms makes conventional antibiotics ineffective and dampens immune clearance. Therefore, it is important to understand the mechanisms of biofilm formation and develop novel strategies to treat biofilms more effectively. This review article begins with an introduction to biofilm formation in various clinical scenarios and their corresponding therapy. Established biofilm models used in research are then summarized. The potential targets which may assist in the development of new strategies for combating biofilms are further discussed. The novel technologies developed recently for the prevention and treatment …

Center For Manufacturing Excellence Capstone Project: Sec Rivals Checkers, Ward Winstead

Honors Theses

Each year, the seniors in the Haley Barbour Center for Manufacturing Excellence complete a capstone project. A team comprised of seniors in varying disciplines work to develop a business model focused on producing a specific product. This team, SEC Rivals Checkers, chose to produce wooden checker boards where each half of a board is custom to a specific SEC school. These halves were designed to be interchangeable, so a variety of different combination could be created when utilizing the product. Through initial marketing analysis, cost estimation, prototyping, and process development, the original SEC Rivals Checkers idea was developed into a …

Minimizing Control Circuits Using Logic Elements, R.T. Gaziyeva, A.M. Nigmatov, E.O. Ozodov

Irrigation and Melioration

In this article considered information about contact and non-contact automation. In most cases, contact automation is used in many pumping stations. These phenomena are a power surge or voltage drop. And also the use of contact automation occupies a large place and inconvenience in operation. Non- contactless automation solves these problems. Pumping stations are usually designed with the calculation of their operation without permanent duty personnel. At large stations, a small staff is provided, which primarily carries out control functions. Set the automatic operation of pumping units. Often, automatic selection of switched-on units is carried out, reserve is withdrawn, station …

Initiating Event Analysis Of A Lithium Fluoride Thorium Reactor, Nicholas Charles Geraci

Engineering Management & Systems Engineering Theses & Dissertations

The primary purpose of this study is to perform an Initiating Event Analysis for a Lithium Fluoride Thorium Reactor (LFTR) as the first step of a Probabilistic Safety Assessment (PSA). The major objective of the research is to compile a list of key initiating events capable of resulting in failure of safety systems and release of radioactive material from the LFTR.

Due to the complex interactions between engineering design, component reliability and human reliability, probabilistic safety assessments are most useful when the scope is limited to a single reactor plant. Thus, this thesis will study the LFTR design proposed by …

Mentoring Management Database, Alexandra Cava, Samantha Kin

Industrial and Manufacturing Engineering

A new mentoring program is set to begin next year pairing children from Kindergarten through 12th grade with college students as their mentors. Keeping track of the mentor information, mentee information, pairings, stipend disbursements, interview question results, events, and final assessments by hand would be extremely difficult, therefore, a database would be a great asset to the program.

Creating a database in Microsoft Access allows a user to have all this information in one convenient location, therefore, ensuring there is a good user interface is a key component to this project. Using Perach’s "Guide to the Perplexed" as the base …

Prosthetic Thermal Management Device, Garrett Dowd

Williams Honors College, Honors Research Projects

High temperatures in lower-limb prosthetics can lead to poor user skin conditions and mechanical slippage between the user’s limb and the prosthetic. This report presents an air-cooling device for a lower-limb prosthesis. This device’s purpose is to maintain a constant skin-prosthesis interface temperature. A compact heat sink and small fan were used to transfer the bio-heat to the ambient surroundings. By changing the power of the fan, the thermal resistance of the whole system can be adjusted to match various thermal loads and environmental temperatures. Heat pads were used to mimic the heat generation of a residual limb, and cooling …

Implementation Of Sql Server Database And Business Intelligence In An Oil And Gas Industry, Pranay Papishetty

Culminating Projects in Mechanical and Manufacturing Engineering

The main objective of this project was to meet the needs of data management, capturing data from various data sources and integrating the data into a database for reporting purposes. This was achieved previously using a legacy system called as FOCUS and is now replaced by a database using SQL Server Business Intelligence. SQL Service Business Intelligence is not only used to load data into the database but also provides tools for reporting and analysis services. Loading data is done using a tool provided by SQL Server called as SSIS and reporting or representation of data is done using another …

Modification Of A Draw Bar Type Arena Harrow To Three Point Mounted Type Harrow, Clayton Alan Brown

BioResource and Agricultural Engineering

This senior project will be the design, and construction of a three point hitch to be attached to a draw bar type spike tooth harrow. Currently used by the Cal Poly Rodeo Team to cultivate their arena before performances, and practices.

The attachment will allow the harrow to be pulled in both directions to create different types of soil affects.

Also the fabrications has a minimal budget so the majority of the materials will be scrap material already in position of the rodeo team or donated to the project.

An Empirical Study On Quality Management Practices, Organization Performance And Suppliers' Selection In Southern Minnesota Manufacturing Firms, Rachel Yetunde-Abiodun Awoku

All Graduate Theses, Dissertations, and Other Capstone Projects

Quality management systems (QMS) have been widely applied successfully by many manufacturing companies to improve their process, increase profits and organizational performance. The most applied of the quality programs are ISO 9001, Total Quality Management (TQM), Just-In-time (JIT), Lean Management and Six Sigma. Although past studies on quality management have identified and studied the implementation of quality management practices, there is little or no research on quality management practices and business performance in Southern Minnesota manufacturing companies. Many researchers have concluded that the implementation of quality management practices has led to significant improvements in companies' business performance while others have …

Root Cause Analysis Applied To Transition To Production, Troy Pierson

Culminating Projects in Mechanical and Manufacturing Engineering

This study examines problems that arise during transition to production of a complex system. It focuses on a single component of the system as a representative of the whole to illustrate how three common production concerns can be addressed: (a) late delivery of the first production part, (b) the ongoing production of non-conforming parts, and ( c) predicting/preventing future interruptions of continuous production. Focusing on the Analysis process of the Six Sigma DMAIC methodology, this study centers on a structured approach to problem solving by applying root cause analysis techniques to identify key causation factors. Results of this study indicate …
