The Sunlight Effect On Trace Pollutants In Wastewater, Alan R. Sheu

Theses

In order to study the sunlight effect on the degradation rate of trace pollutants, ortho-cresol was selected to serve as a model compound in our studies. Solution of ortho-cresol alone, methylene blue alone, and the mixture of ortho-cresol and methylene blue were exposed to sunlight for more than four hours and aliquots analyzed with a spectrophotometer in order to follow the changes in absorption. Rate data were obtained for these three cases as a function of pH.

The results indicate that methylene blue does catalyze the degradation of ortho-cresol in the presence of sunlight with lower pH's affording higher reaction …

Just-In-Time In The United States : Culture And Competitive Manufacturing, Wolfram Pabst Von Ohain

Theses

Richard Schonberger, 'the' Guru of Just-in-Time' in the United States, wrote in the preface of his 1986 book World Class Manufacturing:

"...Japanese success is rot mature-based. Its basis is a quite different set of concepts, principles, policies, and techniques for managing and operating a manufacturing enterprise. All of it is easy to understand, not hand to accept (once known), eminently teachable and learnable, and not so difficult to apply.

If Just-in-Time is such 'a piece of cake' one would expect that most American companies would practice Just-in-Time. As commonly known, most American companies do not follow the philosophy of Just-in-Time. …

The primary objective for this thesis is to collect and analyze data on how a new model for business organizations might best be formulated. There seems to be a consensus among authorities in the field that because modern business practices are so complex, indeed they have been revolutionized in many areas in the past decade. New organizational techniques must be devised if organizations are to remain as effective and as efficient as in the previous area. Some have claimed that the present structural model has reached the point of no return-that is, no longer functional because of such factors as …

Finite Element Stress Analysis Of The Femoral Hip Stem Prosthesis - Bone Interface, Mark C. Buechel

Theses

A three-dimensional finite element model is used to examine the stresses of the femoral hip stem prosthesis and surrounding bone, specifically at the interface between the stem and the bone. Using General Electric's GEOMOD modelling program, 3-dimensional models of the hip stem prosthesis, and both the cortical and cancellous bone, are generated. Due to the complexity of the individual models, General Electric's SUPERTAB modelling program is required to merge the three separate models into one complete model. The model is then broken down into finite elements for analysis. The model assumes isotropic properties to cortical bone and cancellous bone. Several …

Recruitment Of Engineers In A Small Company, Robert Cohen

Theses

With most recruitment techniques written for large companies, recruitment of engineers in a small company may be a large problem. A detailed analysis of the engineering employer and employee is constructed making note of large and small company differences. A survey was taken and the results are presented in support of the authors opinions. A generic recruitment technique is also presented, followed by modifications or other considerations to that technique.

A Study Of White-Collar Clerical Productivity : Composition, Issues And Implications For Human Resource Planning, Sheila Devereaux

Theses

During the past decade, there has been a growing concern and focus over declining American productivity. Declining productivity requires long-range thinking, and fundamental changes on the part of government, labor and management.

One of the major contributors identified is the labor force. What has gone unmeasured for years is the white-collar clerical workforce. The service sector has become the most dominant area where clerical workers have increased, consequently, productivity issues have become a top priority.

Management must assess the implications of losses in turnover, absenteeism, performance lag, and morale that affects bottom-line profits. Management is under pressure to develop action …

Human Resource Planning For Mergers And Acquisitions, Thomas Jide Fiki

Theses

When a firm is acquired or merged, everyone feels shaken.

When organizations merge, the people in them are touched by several real and poignant issues, with each issue having the potential for lowering morale and productivity. When mergers or acquisitions fail, either by falling short of stated objectives or more disastrously - by divestiture - a chief culprit is often inadequate or nonexistent human resource planning.

A solid people plan - which takes into account what and how to communicate before and during a merger not only helps retain a semblance of order and direction within the company facing a …

Indicators Of Microbial Activity In Biological Treatment Of Hazardous Wastes, Alexander Mclean Sherrin

Theses

Three methods were used to measure the activity of mixed liquor from the Livingston, N.J. municipal wastewater treatment plant on exposure to phenol. The three methods were, substrate removal rate (SRR), dissolved oxygen uptake rate (DOUR), and the dye reduction rate (DRR). Parameters from each test were compared for reproducibility and ease of determination. The SRR test gave the most reproducible results, while the DOUR test was the least reproducible. Although the reproducibility of the DRR test was close to that of the SRR test, the DRR was more time consuming and required a greater degree of expertise and training. …

Process Hazard Review For Drug Development, Rudolph R. Schwarz

Theses

The development of drugs has become increasingly complex, requiring the use of a wide variety of pharmaceutical actives and isolated intermediates, a majority of which are not always completely characterized with respect to their hazard potential. This can present a source of potential exposure to those who handle these substances during initial drug development, manufacturing of the drug active and ultimately the finished pharamaceutical product. It is, therefore, essential that safety and health information be documented and communicated during the entire drug development process.

The need for application of process hazard review techniques to the development of new drug materials …

Construction Labor And Productivity : Productivity Improvements, Stavros C. Nicolaou

Theses

Construction productivity has been on the decline in the last decade. Although an important factor in the nation's economy, productivity of construction labor has been given little attention over the years. A review of the literature dealing with construction was performed that revealed the importance of the declining productivity as well as the confusion among construction managers and labor leaders as to what productivity is all about and how it can be improved. It has been found also, that construction labor motivation, which is the most important factor in improving productivity, is almost nonexist. Very few construction companies employ any …

Alternatives To Lay Off, Davidson Nwaneri Okere

Theses

In the recent years, there have been some changes in the American corporate life. These changes have been occasioned by some external factors which adversely affect the profitability of the companies. In order to address this problem, many corporations have resorted to cutbacks which more often than not, affect a great bulk of the human resources.

The purpose of this study therefore, is to explore the strategies which companies could use, rather than lay off, during business downturns; and still remain competitive and profitable.

Chapter one of this study focuses on what companies should do to help the affected workers …

Stress And Today's Working Woman, Tommie Mae Byers

Theses

The eighth wonder of the world is fast becoming the great American job machine The employment rate has declined in most industrial nations while 20 million jobs have been created in the U. S. during the past 10 years. The principal reason for this rise in job placements is the large influx of women into the labor force.

Two-thirds of the jobs created over the past decade have been seized by women. The post-industrial environment which has produced an extensive number of service-type businesses has substantially opened the job market for women. Financial experts will contend that an expanding labor …

Analysis And Evaluation Of The "Pay For Savings" Concept : The Residential Energy Conservation Action Program (Recap), Glenn Owen Steiger

Theses

Recently, electric utilities have developed and implemented many methods to induce their customers to reduce consumption of electricity. One of the most unique concepts was developed by the General Public Utilities Corporation. Simply, it is the "Pay for Savings" concept which pays energy conservation contractors for actual (measured) energy saved, and not for the retrofit measures used to accomplish the savings. GPU has developed a program, Residential Energy Conservation Action Program, as a vehicle for this concept.

This thesis has attempted to describe the methodology used in implementing RECAP. More importantly, it has analyzed actual results of the program and …

White Chief: The Story Of Edward H. Davis, Charles Mitchell Hudgins

Theses

With Mother Earth for a couch, To sleep under the fragrant conifers; To breath the purity of the ranges; To watch the procession of the constellations; To listen to the music of the wind harps of the sierras; To leave care, worry, responsibilities behind us; To be in harmony with nature at all times; To live simply, to think severely, the love deeply, to be content; And to learn patience and tolerance from the mighty mountains; That me thinks is to be happy. Edward H. Davis Mesa Grande August 26, 1933
