Improvement Of Mechanical Properties And Water Stability Of Vegetable Protein Based Plastics, Gowrishankar Srinivasan Sep 2015

Improvement Of Mechanical Properties And Water Stability Of Vegetable Protein Based Plastics, Gowrishankar Srinivasan

Gowrishankar Srinivasan

Bio-renewable bio-degradable plastics are a potential solution to the growing problems of pollution caused by petroleum plastics and dependency on foreign nations for petroleum resources. One possible feed stock for these materials are vegetable proteins, especially from soy bean and corn. These proteins have relatively high molecular weights and have the potential of being processed with standard polymer processing technologies. But some issues that need to be addressed are their water instability (soy protein) and inferior mechanical properties as compared to petroleum derived plastics. In this study, soy protein isolates (SPI) and zein protein was processed with various additives and ...

The Effects Of A Safety Climate On Safety Decision-Making, Troy Ricardo Mills Jan 2007

The Effects Of A Safety Climate On Safety Decision-Making, Troy Ricardo Mills

Retrospective Theses and Dissertations

This study examines the relationship between the strength of safety climate and the orientation towards safety in a decision-making process ( Safety Decision-Making). The study attempted to answer the following question: Can the strength of a safety climate predict safer decision-making process and choice?;Two web-based instruments have been utilized to address the question above: a safety climate survey followed by decision-making simulation (Decision Mind(TM)).;The study was conducted in a manufacturing facility in Iowa. It included 111 of the 186 employees in the facility. The results indicated that an aggregated measure of the strength of safety climate was a ...


The Impacts Of A Formal Quality Management System: A Case Study Of Implementing Iso 9000 At Farmers Cooperative Co., Iowa, Chad Matthew Laux Jan 2007

The Impacts Of A Formal Quality Management System: A Case Study Of Implementing Iso 9000 At Farmers Cooperative Co., Iowa, Chad Matthew Laux

Retrospective Theses and Dissertations

We are in an age of great change for agriculture. The effect of globalization is changing the industry that 20 years ago were unforeseeable: the rise of biotechnology use, food safety concerns, fears of bioterroism, and increasing consumer demands. These developments result in an altered landscape of agribusiness management. Managing these developments requires an understanding of the collection of rules: regulatory (business/government), product requirements (business/consumer), and operating practices (business/customer) that defines how the modern company in agriculture operates in this environment.;In respond to these issues, the use of quality management systems (QMS) have filled in on ...
