Regulation of Receptors in Neuronal Cilia with Development, Seizures, and Knockouts: Implications for Excitability

Description: Neurons commonly have a primary cilium, which is a non-motile organelle extending from the centrosome into the extracellular space. In most brain regions, neuronal cilia are enriched in either somatostatin receptor type 3 (SstR3) or melanin concentrating hormone receptor type 1 (MCHR1), or both. The present immunohistochemical study provides novel evidence that primary cilia regulate neuronal excitability via G-protein coupled receptors (GPCRs), and that their identity is governed by brain re… more

Electrical Conduction Mechanisms in the Disordered Material System P-type Hydrogenated Amorphous Silicon

Description: The electrical and optical properties of boron doped hydrogenated amorphous silicon thin films (a-Si) were investigated to determine the effect of boron and hydrogen incorporation on carrier transport. The a-Si thin films were grown by plasma enhanced chemical vapor deposition (PECVD) at various boron concentrations, hydrogen dilutions, and at differing growth temperatures. The temperature dependent conductivity generally follows the hopping conduction model. Above a critical temperature, the d… more

Micro-Pipette Thermal Sensor: A Unique Technique for Thermal Characterization of Microfluids, Microsphere, and Biological Cell

Description: In this research work, an innovative method for measurement of thermal conductivity of a small volume of liquids, microsphere, and the single cancer cell is demonstrated using a micro-pipette thermal sensor (MPTS). The method is based on laser point heating thermometry (LPHT) and transient heat transfer. When a single pulse of a laser beam heats the sensor tip which is in contact with the surrounding liquids or microsphere/cells, the temperature change in the sensor is reliant on the thermal pr… more

N-Acylethanolamine Metabolism During Seed Germination: Molecular Identification of a Functional N-Acylethanolamine Amidohydrolase

Description: N-Acylethanolamines (NAEs) are endogenous lipid metabolites that occur in a variety of dry seeds, and their levels decline rapidly during the first few hours of imbibition (Chapman et al., 1999, Plant Physiol., 120:1157-1164). Biochemical studies supported the existence of an NAE amidohydrolase activity in seeds and seedlings, and efforts were directed toward identification of DNA sequences encoding this enzyme. Mammalian tissues metabolize NAEs via an amidase enzyme designated fatty acid amid… more

Understanding the Micromechanism of Cyclic Loading Behavior of Ultrafine Grained Alloys

Description: In the current study, we have investigated the cyclic loading behavior of conventional as well as novel alloy system exhibiting fine and ultrafine-grained structure. While in case of conventional alloy systems (here aluminum alloy AA5024), the effect of three different grain sizes was investigated. Improvement in fatigue properties was observed with decreasing grain size. The unique microstructure produced via Friction stir processing was responsible for the improved fatigue response. Additiona… more

Who is Who in Zimbabwe's Armed Revolution? Representation of the ZAPU/ZIPRA and the ZANU/ZANLA in High School History Textbooks Narratives of the Liberation War

Description: The liberation war was a watershed event in the history of Zimbabwe. According to the ZANU PF (Zimbabwe African National Union Patriotic Front) ruling elites, an understanding of the common experiences of the people during the liberation war provides the best opportunity to mold a common national identity and consciousness. However, the representation of important historical events in a nation's history is problematic. At best events are manipulated for political purposes by the ruling elites, … more

On the Nature of Melody in Asia and Medieval Europe

Description: In current musicological research, considerable attention is given to the description of melodic structure and pitch organization. But it is problematical that the analytical concepts and terminology of the Common Practice Era are largely inadequate for meaningful description of melody of Asia and medieval Europe. For most traditions of melody in Asia and medieval Europe, there is some sort of developed system of theory, but each system is limited to the repertory it describes. Consequently, th… more

Exploring the Conceptualization, Operationalization, and Application of Relational Mindfulness

Description: Individuals vary in the level of their mental presence during interactions; some individuals are mentally present with others, while others are mired in their thoughts and emotions. Scholarly work on this area is limited, and we know very little about why some individuals display mental presence better than others. In this dissertation, I explore the concept through a series of three essays. In the first essay, I define relational mindfulness as the ability to be mentally present with others… more
