Through-Wafer Interrogation Of Mems Device Motion, Jeremy Michael Dawson
Through-Wafer Interrogation Of Mems Device Motion, Jeremy Michael Dawson
Graduate Theses, Dissertations, and Problem Reports (ETD)
Microelectromechanical systems (MEMS) have been the focus of many research groups because of their wide variety of uses in sensing and actuation applications. A fundamental barrier facing designers of next generation MEMS is the inability to access accurate, real-time microstructure positional information to determine if the device is performing as expected. Previously explored optical and electrical methods of MEMS device monitoring are often only suitable for research environments, or are unable to produce clear and meaningful characterization of device motion. The most desirable MEMS monitoring method would be one that could be implemented at the device level, which would allow …

Effect Of Sward Height And Concentrate Supplementation On Forage Dry Matter Intake, Digestibility And Grazing Time Of Spring-Calving Beef Cows, Ondieki J. Gekara
Graduate Theses, Dissertations, and Problem Reports (ETD)
To establish the effect of sward height (SH) and concentrate supplementation on performance of grazing cattle, twenty-four cross bred Angus beef cow-calves were randomly assigned to two SH treatments (4--8 or 8--11 cm) with three supplement levels: 6.24, 3.12 or 0 kg/d. The study was conducted in three periods (P): May (P1), June/July (P2) and August (P3) in 1996. There was no SH x supplement level x period or SH x supplement level interaction (P > .10) on forage DMI, DMD or grazing time (GT). Cows on low SH had greater (P < .08) DMI and GT (P < .01) than cows on high SH. Forage DMI, DMD and GT decreased (P < .05) with supplementation. Grazing efficiency declined with supplementation and advancing grazing season (P < .01). Cows consumed more forage DM (P < .01) in P1 and P2 than P3. Forage DMI and grazing efficiency decreased with supplementation suggesting that supplemented cattle can optimally be grazed at SH < 8 cm.

Various Pushing Methods On Grid Graphs, Jiaxin Wang
Graduate Theses, Dissertations, and Problem Reports (ETD)
This thesis describes algorithms for determining if a grid of switches can be turned into all-off state from any initial configuration by various methods of activation operation (push). Among these push methods, besides the regular "+" push, "+" push with no center, "X" push, "X" push with no center, and a "V"-typed unbalanced push are studied. The research methods used in this work are mainly linear algebra and algorithm analysis. Results obtained include that the grid m x n is completely solvable with push "+" no center, if and only if co-prime (m+1, n+1).
Influence Of Selection For Breast Muscle Mass On Ph And Metabolism Of Supracoracoideus Muscle From Male And Female Turkey, John Kenneth Yost
Influence Of Selection For Breast Muscle Mass On Ph And Metabolism Of Supracoracoideus Muscle From Male And Female Turkey, John Kenneth Yost
Graduate Theses, Dissertations, and Problem Reports (ETD)
The objective of this study was to determine if selection for increased breast muscle mass has affected the supracoracoideus muscle's ability to regulate pH during physical activity in turkeys. The lightweight male line (LM) had the greatest breast muscle mass as a percent of body weight (p < 0.0001), a lower average pH (6.68; p < 0.0001), and greater Lactate Dehydrogenase (293 mmol NADH min-1mug-1 ; p < 0.0001) and Glyceraldehyde Phosphate Dehydrogenase (0.4452 mmol NADH min-1mug-1; p < 0.05) activities than the HM and FL lines. The LM line had the highest ratio (2.33:1) (p < 0.05) of adult to neonatal myosin. Hens had greater breast muscle mass as a percent of body weight than males (p < 0.0001), and a lower average pH (6.62; p < 0.05). This study showed that genetic selection for breast muscle mass resulted in an increased ratio of adult to neonatal myosin and an increased anaerobic capacity, which may predispose birds to a lower ultimate pH during physical activity.

Synthesis Of O-Isotoluenes, O-Quinodimethanes, And Benzoenynyl Carbodiimides And Their Cyclizations To Polycyclic And Heterocyclic Compounds, Quan Zhang
Graduate Theses, Dissertations, and Problem Reports (ETD)
Treatment of alkenyldicyclohexylboranes with 1-lithio-5-butyl-3,4-nonadien-1-yne, derived from 5-butyl-3,4-nonadien-1-yne, followed by trimethyltin chloride and acetic acid furnished the corresponding o-isotoluenes in a single operation. The reaction proceeded through an initial formation of (Z)-diene-allenes, which underwent facile eletrocyclizations to produce o-isotoluenes.;Treatment of allenyldicyclohexylborane with 1-lithio-5,5-pentamethylene-3,4-pentadien-1-yne produced the organoborate complex, which on further treatment with trimethyltin chloride furnished a (Z)-1,2,4,6,7-octapentaene (enediallene) derivative in situ. The subsequent electrocyclic reaction then generated the corresponding o-quinodimethane attached with a dicyclohexylboryl group and a trimethyltin group. The resulting o-quinodimethane then underwent a [1,5]-sigmatropic hydrogen shift, and on subsequent oxidative workup and protonation gave the 4-(1-cyclohexenyl)-3-methylphenol (51%). The …
A Study Of The Japanese Reflexive Pronouns, Zibun And Zibun-Zisin, Masaru Yamada
A Study Of The Japanese Reflexive Pronouns, Zibun And Zibun-Zisin, Masaru Yamada
Graduate Theses, Dissertations, and Problem Reports (ETD)
The behavior of various types of anaphors may be classified into two types, local and long-distance anaphors. The English reflexive 'himself' and the Japanese reflexive 'zibun' representatively characterize the two types of anaphors. They contrast in that 'himself' is a local anaphor, whereas 'zibun' is a long-distance anaphor. Japanese has another reflexive pronoun, `zibun-zisin', and it behaves more similarly to himself. The standard binding theory (Chomsky (1981)) regulates the behavior of local anaphors; however, the behavior of long-distance anaphors cannot be explained. One proposal for this matter is to invoke parameterization, which defines a language-specific binding domain for anaphors. Within …
