A Ten-Year Evaluation Of Structural And Compositional Development In Unmanaged Central Appalachian Clearcuts, Jonathan R. Marden

Graduate Theses, Dissertations, and Problem Reports (ETD)

The varied growing conditions, fractured topography, and diversity of woody species in the Central Appalachians ensure that the harvest response of forest stands in the region will never be easily predictable. Clearcutting exposes the seedbed and freshly cut stumps of a harvested forest to full sunlight, encouraging the regeneration of the greatest number of species possible for that region. Gathering information on stand response to a complete removal in the mixed mesophytic forests of West Virginia will add valuable information to the silvicultural database for the most complex hardwood ecosystem in North America.;Beginning in 1998, U.S. Forest Service personnel installed …

Regulation Of Anoikis By Ankyrin Complexes, Sanjeev Kumar Jan 2010

Regulation Of Anoikis By Ankyrin Complexes, Sanjeev Kumar

Graduate Theses, Dissertations, and Problem Reports (ETD)

Anoikis is a subset of apoptosis, suppressed by cell-extracellular matrix association. It is a safeguard mechanism against tumor metastasis. The present study was designed to understand the role of cortical cytoskeletal protein ankyrin-G and its interacting proteins in anoikis. E-cadherin and ankyrin-G are function partners and during epithelial-mesenchymal-transition (EMT), both gets downregulated. During cell-extracellular matrix dissociation, ankyrin-G shifts to cytoplasm from cytoskeleton and loses spectrin interaction. Overexpression of ankyrin-G induced apoptosis in death domain dependent manner, promoted by the presence of ankyrin-G death domain interacting partner, RIP1 (Receptor Interacting Protein with death domain). Ankyrin-G also interacted with a MAGE family …

Characteristics Of Subordinate Follicles Following Removal Of The Dominant Follicle: Induction Of Selection, Matthew Dean Dec 2009

Characteristics Of Subordinate Follicles Following Removal Of The Dominant Follicle: Induction Of Selection, Matthew Dean

Graduate Theses, Dissertations, and Problem Reports (ETD)

In mammals, ovarian follicles begin as primordial follicles. Over time these follicles are gradually activated and begin growth. As they proceed, granulosal and thecal cells are acquired. Eventually, the follicles become dependent on FSH for survival. Two or three times each cycle, a transient increase in FSH allows a cohort of follicles, including the follicle that will ovulate, to continue growing. However, these follicles secrete inhibin and estradiol, which suppress FSH secretion. Eventually, all the follicles of the cohort undergo atresia due to the declining concentrations of FSH, except for the follicle which has the potential to ovulate. This follicle …

Optimization Of A Retrofit Urea-Scr System, Clinton R. Bedick

Graduate Theses, Dissertations, and Problem Reports (ETD)

Oxides of nitrogen (NOx) emissions from legacy diesel engines are often many times over currently mandated standards, contributing significantly to degradation of air quality and negative environmental impact. A retrofit urea-SCR (selective catalytic reduction) aftertreatment system offers a viable solution for reducing NOx emissions from older diesel engines. A stand-alone retrofit urea-SCR aftertreatment system was previously developed by West Virignia University (WVU) engineers, implementing a pre-SCR NOx sensor, open-loop feed-forward control, and stoichiometric NOx reduction logic. During experimental testing at WVU, the urea-SCR system demonstrated NOx reductions of 2% to 53%, depending on the test cycle. In order to optimize …

The Fearful Face And Beyond: Fmri Studies Of The Human Amygdala, Jillian E. Hardee Dec 2009

The Fearful Face And Beyond: Fmri Studies Of The Human Amygdala, Jillian E. Hardee

Graduate Theses, Dissertations, and Problem Reports (ETD)

The amygdala has been labeled as a "detector of threat", evidenced by its heightened response to fearful faces in human neuroimaging studies. A critical element of the fearful face is an increase in eye white area, hypothesized to be crucial for the rapid detection of fear in another's face. Yet other facial expressions can also increase eye white area in a manner that is similar (a lateral shift in gaze) or identical (surprise) to fear. It is unknown if the amygdala can differentiate between these types of increases in eye white area and those that are specifically associated with fear …

Interleukin (Il)-1 Regulates Ozone-Induced Nerve Growth Factor (Ngf) And Substance P (Sp) Release In Bronchoalveolar Lavage Fluid (Balf) In Mice, Joshua S. Barker Dec 2009

Interleukin (Il)-1 Regulates Ozone-Induced Nerve Growth Factor (Ngf) And Substance P (Sp) Release In Bronchoalveolar Lavage Fluid (Balf) In Mice, Joshua S. Barker

Graduate Theses, Dissertations, and Problem Reports (ETD)

Previous studies show that both IL-1 and NGF increase synthesis of SP in airway neurons after either direct application or ozone exposure. We hypothesize that NGF mediates ozone-induced IL-1 effects on SP, similar to the pathway described for sympathetic neurons in culture. The current study specifically focuses on the effect of ozone on IL-1, NGF, and SP levels in mice BALF and if these mediators can be linked in an inflammatory-neuronal cascade in vivo. The experiments demonstrate in vivo ozone exposure induces an increase of all three proteins in mouse BALF and that both ozone-induced increases in NGF and SP …

Historical Response Rates, Reinforcement Context, And Behavioral Persistence, Chata A. Dickson Dec 2009

Historical Response Rates, Reinforcement Context, And Behavioral Persistence, Chata A. Dickson

Graduate Theses, Dissertations, and Problem Reports (ETD)

In several studies, historically lower-rate responding has been found to be more persistent than historically higher-rate responding (e.g., Lattal, 1989; Nevin, 1974). In these studies, historical response-rate differences were generated by reinforcement schedules (e.g., fixed-ratio [FR] and differential-reinforcement-of-low-rates-of-responding [DRL]) that directly affect response rate. The current study was conducted with pigeons pecking keys to determine whether this finding would hold when response-rate differences were generated by the context of reinforcement, such as a concurrently available source of reinforcement or schedule of response-independent food. In each of 3 experiments, a history-building condition was followed by a history-testing condition. In Experiment 1, …
