Statistical Study of Supply Chain Developmental Training on Original Equipment Manufacturer’s Defect Rates
Learning is an amalgam of a student’s desire to understand, the willingness of an instructor to educate, the subject taught, its quality, and the delivery environment. Most importantly, a learning goal, both actionable and investment worthy, must exist for effective learning to take place. The ability to learn and then implement new concepts and ideas is the significant difference separating our species from other life on this planet. It has led to diverse discoveries such as disease vaccines, nuclear energy, the automobile, electronics, and rocket planes to name just a few.Science advances in small steps and big leaps. Inventions increase daily to improve the quality of life for this planet’s population. At the center of all these ideas are researchers looking to tease out the next piece of information for our world’s knowledge base. This body of knowledge (BOK) grows at an ever-expanding rate, doubling every few years. This doubling period is shrinking rapidly as more knowledge is accumulated.In the manufacturing world of products, this BOK is brought to bear on products that, hopefully, stand above their competition. If a product is excellent, consumers and producers are satisfied. The consumer gets the best quality for the price while the producer gets the best price for the quality offered. If product quality and price are right, there is someone willing to buy it.However, what happens when the opposite is experienced and the product, at its asking price, is of poor quality? Buyers are less willing to spend and quick to mention the lack of quality or defects found. Defects can impact the maker’s selling price and translate into extensive efforts to make the customer whole through warranty. The producer also risks the loss of their customer (brand loyalty) if the product is deficient in quality.Within this dissertation, training methods, useful practices, experiences, and the body of training knowledge will be presented in defense of developmental training and will conclude with a case study exploration into the connections between supply chain developmental training and defect reductions at an Original Equipment Manufacturer (OEM) using multiple statistical techniques
Freshwater Plankton Crustacea of the Colville River Area, Northern Alaska
Reports study of Microcrustacea from 200 water bodies, collected during the summer of 1955. Twenty-two species of Cladocera, 29 Copepoda and six larger forms were identified. Some species characteristic of lakes or pools are separated. Surface temperatures ranged from 0.5 to 20.5 C. Chemical determinations of 48 water bodies include chloride, calcium, bicarbonate and oxygen. Similarities with Siberian and other high latitude forms are noted
Disturbed Sediments in a Small Alpine Lake in Colorado
Palynologists, students of paleolimnology and others interested in former ecological conditions may study cores of sediments deposited in present or now-dry lake basins. Undisturbed sequences are crucial to drawing correct inferences from sedimentary records. Recently Nichols called attention to the disruption of tundra pond sediments by blocks of ice floating from the basin bottom to the water surface. This note records the derangement of sediments in a small alpine lake; while the actual disturbance was not witnessed, this type of event may be of frequent occurrence in remote mountainous areas and go unnoticed. Among the lakes receiving limnological study in Rocky Mountain National Park is a small unnamed tarn at the head of Fern Creek, a tributary of the Big Thompson River ...
ELECTROCHEMICAL AND SURFACE ENHANCED RESONANCE RAMAN STUDY OF HEME PROTEINS AT BARE METAL ELECTRODES
Direct heterogeneous electron transfer reactions between horse heart cytochrome g_and silver electrodes were investigated by electrochemical and spectroelectrochemical methods. The kinetics of these reactions were established as being quasi-reversible, with a formal heterogeneous rate constant (k°\u27s,h) ranging between 0.18 - 1.5 x 10-3 cm/s, for both polished and electrochemically roughened silver surfaces. Such reactions were stable and reproducible for over ten hours at room temperature. These results clearly demonstrate that neither electrode surface modification nor the inclusion of mediators is necessary to study electron transfer reactions of heme proteins at metal electrodes.
A crucial factor in obtaining the quasi-reversible heterogeneous electron transfer kinetics described above is the use of highly purified, never lyophilized, cytochrome c samples. When samples were lyophilized after purification, irreversible electron transfer kinetics were observed. These results show the profound negative impact that lyophilization has on the rates of electron transfer at bare metal electrodes. The lyophilization process was indicated to produce small amounts of oligomeric material which rapidly and irreversibly absorbs on the electrode surface preventing further solution cytochrome c molecules from reacting. This denatured form, along with other solution impurities, is believed to be the reason for the lack of stable facile responses towards metal electrodes.
Surface enhanced resonance Raman spectroscopy was used to monitor conformational changes associated with the direct electron transfer reactions of purified cytochrome c at silver electrodes. The results of this study indicated that cytochrome c exists in a penta-coordinate high spin configuration, with a formal potential =0.350 volts more negative than its corresponding bulk solution value when adsorbed. This suggests that cytochrome c is still capable of exchanging electrons in a quasi-reversible fashion even though there is strong irreversible adsorption of a denatured form on the electrode surface
