A comparison of total bacteria counts of raw and pasteurized milk

The purpose of this study was to compare the total bacteria count in samples of raw and pasteurized milk from the Golden Guernsey Association, of Indianapolis, Ind., using both the Breed-Prescott direct microscopic method and the standard agar plate method. In addition, a record of the types of organisms observed in the direct microscopic count was made for each sample

The Effects of Various Physical and Chemical Agents on a Staphylococcus Bacteriophage

In recent years considerable attention has been focused on a group of organisms known as bacterial viruses or bacteriophages. These minute virus particles are parasitic upon bacterial cells and probably most bacteria are susceptible to one or more of them. There are several excellent reviews and symposia covering the various steps of bacteriophage multiplication and the effects of inhibiting agents. The reader is referred to them for an explanation of the process involved in attachment to and multiplication within the host cell

A Comparison of the Needs and Values of Experienced Teachers of Special Education and the Needs and Values of Experienced Teachers of Regular Education

This study used the II:PPS and the AVLSV to test seven hypotheses. These hypotheses asked if there was significant difference at the .05 level as measured by the t test between experienced teachers of special education and incoming prospective teachers of special education, of experienced teachers of special education and graduating prospective teachers of special education, and of experienced teachers of special education and the college normal samples as published by the test manual. The hypotheses asked the same questions as related to regular teachers of education. In addition, the hypotheses asked if there was a difference between experienced teachers of special education and experienced teachers of regular education. The results indicated that there were fourteen areas of significant difference

‘My Freedom is a Privilege Which Nothing Else Can Equal’: The Life and Writings of Venture Smith and Phillis Wheatley, American Slaves

Slavery in the United States was an evolving institution that lasted nearly 400 years. To understand the colonial era of slavery within the United States, I examine the life and times of Venture Smith, as documented in his autobiography, A Narrative of the Life and Adventures of Venture, A Native of Africa (1798), and that of Phillis Wheatley using The Collected Works of Phillis Wheatley (1988). Both Smith and Wheatley were African-born slaves brought to America during the eighteenth century. In Smith’s narrative, he concludes by proclaiming “my freedom is a privilege which nothing else can equal” (31). This statement is used as the title of this project because it shows that Smith and Wheatley understood that freedom is not an abstract concept. Living in a society that relied on slave labor, Wheatley and Smith write extensively about their experiences of being treated as inferiors in America. Having been born free is what distinguishes their experiences from African American slaves’ writing later in the nineteenth century. Most of what is known about American slavery is based on the first-hand accounts recorded in such fugitive slave narratives, a genre that developed from the latter generation and influenced by abolitionists. Early African slaves were an integral part of the American colonial society, and they were not just simply house servants or field laborers as they commonly appear in abolitionist literature. Revisionist scholarship guided my study as I examine three themes throughout this research project: society, identity, and the literacy of colonial America slaves. In this essay, I show how Wheatley and Smith wrote freedom narratives and poetry to protest against slavery. I argue that Wheatley, specifically, identified with the black experience of slavery though she lived an exceptional life. More importantly, by using African American literary theory, I explain how Wheatley’s and Smith’s writings reconstruct a black identity in early America, where blackness signified an inferior social class status, though these writers combatted such claims. Also, by using feminist theory and gender studies, I examine Wheatley’s experiences as a black woman and how she claimed her womanhood (essentially her humanity), even though she was classified as slave property for most of her life and writing career. I also use gender theory to examine Smith’s masculinity, as a slave and a free man. With such inquiries, I present a comparative analysis of the difficulty that Wheatley faced to gain her freedom because she was a woman and black slave, whereas Smith’s freedom journey was less arduous considering the patriarchal culture of colonial America

Control Limits Versus Acceptance Limits - Which Limits are Appropriate for Your Task?

The objective of this paper is to discuss and clarify the meaning and use the different statistical limits used in managing processes so the mistakes that are commonly seen in industrial practice can be avoided. The difference between control and acceptance will also be discuss. The idea of this paper was triggered by a recent paper written by Henderson [5] in Quality Progress journal

Using Descriptive Statistics in Statistical Process Control

The purpose of this paper is to demonstrate the various uses of descriptive statistical analysis in statistical process control (SPC). Some fairly well-known descriptive techniques, along with the lesser known methods, will be discussed for their potential use in SPC. A numerical example will be provided
