  1. Cloning of Human Podocin cDNA


    The kidneys are involved in regulating the body's fluid volume. High blood pressure can be caused by too much fluid in the vessels or by having narrow, stiff, or clogged vessels. Diabetes can cause kidney disease by damaging the small blood vessels which leads to loss of function. Podocytes are specialized epithelial cells that surround the glomerulus of the kidney and help filter out proteins and let water, salts, and sugar pass through to form urine. To create a construct specific to the podocytes of kidneys that may be used to regulate blood pressure, I cloned a podocytespecific cDNA(hNHPS2), also...

  2. rapid.fire for solo flute by Jennifer Higdon and its Place in the Flute Repertoire


    rapid.fire for solo flute was published in 1992 and is not what audiences would call a typical piece in the flute repertoire. Extended techniques are abundant, and beautiful melodies that flutists are characteristic of playing are not to be found; rapid.fire turns the flute into a violent and harsh instrument. jennifer higdon has created her own form of notation for events that happen in the music, but she provides many performance notes to aid the flutist. higdon uses techniques such as flutter tongue, overtones, multiphonics, alternate fingerings, pitch bends, and sliding the fingers off the open hole keys to create...

  3. The Importance of Cinema Theory within WSU and the World


    Wright State University's Motion Picture department is spilt into two degrees, one being production, and the other theory, history and criticism. Although students from each focus, interact, and take classes together, there is no actual blend of specific skills into one interaction. Every year the junior class production majors showcase their previous quarter's documentaries to the public, but there is unfortunately no event for an academic conversation between the two focuses. This presentation is an attempt to understand the importance of bridging the widening gap between two degrees within the same major. Using history, theory, and criticism of the documentary...

  4. Conductance modulation in bilayer graphene nanoribbons


    The quantum conductance of single and bilayer graphene nanoribbons (GNR's) are studied for both armchair and zigzag edge structures with finite widths. The conductances are calculated by using the Green's function formalism combined with a density function theory based tight-binding method for the description of the system. Four types of stacking configurations are considered for bilayer nanoribbons with armchair and zigzag edge and quantum conductances were calculated for these systems. Our results reveal that, most stable bilayer structures of AGNR and ZGNR are semiconducting with a band gap of 0.090 eV and 0.054 eV respectively. Interesting modulation effects are seen...

  5. Modeling Exfoliation of Nano Graphene Platelets


    Direct ultrasonication of graphite particles dispersed in water, in the presence of a surfactant, is a promising way to produce pristine nanoscale graphene platelets (NGPs) without graphite intercalation or oxidation. We investigate possible exfoliation mechanisms, specifically those involving sodium dodecylbenzenesulfonate (SOBS) surfactant, and compare their corresponding energies. The model includes interlayer van der Waals interactions and a force-field approach capable of treating charged surfactant and solvent. Our calculations reveal the significant role of SDBS in liquid-phase NGP production, through a locking mechanism that prevents restacking.

  6. Graphene nonoribbons for NO2 sensing


    Nanomaterials provide novel possibilities for sensor applications. Here we investigate nanoelectrochemical sensing of N02 using graphene nanoribbons. Electronic properties of N02 doped nanoribbons are investigated using an ab initio calculations with accurate optimization of the sensor structures. The adsorption of N02 on graphene nanoribbon changes its conduction properties. Therefore, we compare the conduction charateristics of pristine and N02-doped nanoribbons, and investigate the details of N02 sensing based on conduction change.

  7. Aircraft Thermal Modeling


    A system-level thermal management aircraft model has been developed in a multidisciplinary modeling and simulation environment. Individual subsystem models developed exclusively in MATLAB/Simulink, representing the vehicle dynamics, the propulsion, electrical power, and thermal systems, and associated controllers, are combined to investigate the thermal management issues of a typical long range strike platform. A thermal "Tip-to-Tail" model allows conceptual design trade studies of various subsystems and can quantify performance gains across the aircraft. The final result is an aircraft that is thermally optimized at the system-level, rather than at the subsystem-level. In addition, the model has been built without the aid...

  8. Optimization of the Entropy Defined for an Orthogonal Matrix


    The optimization bounds for the Shanon's entropy of an orthogonal matrix have been found for various classes of orthogonal matrices. It has been proved that in the cases when a Hadamard matrix exists, the entropy achieves it's maximum value. For other various cases in which Hadamard matrix does not exist, sharper bounds on the entropy has been found. A general proof for the optimization in case of other equivalent definitions of entropy has been produced.

  9. Multilevel Hadamard Matrices


    Multilevel Hadamard Matrices (MHMs) have been examined by Trihn, Fan, and Gabidulin for constructions of multilevel zero-correlation zone sequences, which in turn have useful application in quasi-synchronus code division multiple access (COMA) systems. Subsequently, Adams, Crawford, Greeley, Lee and Murugan introduced a construction of full-rate circulant MHMs that proved the existence of an order n MHM with n elements of distinct absolute value for all n. We examine MHMs and the family of full-rate circulant MHMs (FCMHMs) introduced by the construction of Adams et al. and explain the existence of other forms of FCMHMs by means of new constructions.

  10. Guns, Steamers, and Quinine: The lasting effects of European expansion in the 19th century


    New Imperial History is a term that describes the work done in recent times by historians of Europe's great nineteenth century empires. These historians sought to examine not merely the story of how those nations became so great but, rather, to examine the means by which those empires spread their culture, values, and technologies, as well as the lasting impact they left on the lands they subjugated. One area that begs for reexamination under the lens of the new imperial historian is the role that science played in the growth, development, and expansion of those empires.

  11. Detective Work: Revision and Writing


    As writers, we may ask ourselves whether or not it is possible to write a perfect first draft. Regardless of the answer, we must admit that this type of writing eliminates a valuable tool in the writer's arsenal. Simultaneously the most rewarding and most frustrating part of writing, revision is absolutely vital. Although revision means editing for grammar and spelling errors, which is the common conception of the process, it also means restructuring, re-writing characters, and sometimes research. The process can be discouraging, as all of the faults with a story come to the forefront, but this is possibly the...

  13. Burning the Mirror: Eavan Boland's Femal Icon Reconstruction


    In my paper, I discuss the reconstruction of the female icon in several poems by Eavan Boland, a contemporary female Irish poet, writer, and critic. The witch, the virginal maid, sinful Eve, and the "fierce mad Queen," are all icons used throughout Literature to represent the female body and psyche in poems by male writers. Each icon allows for the subjectivity of women, giving them roles solely based on their sexual or reproductive qualities. In response, Boland seeks to resurrect and reconstruct these female icons, allowing for an authoritative female voice recovered from the 'otherness' often associated with the feminine...

  14. Freedom of Revision


    While writing a first draft, authors often take the passenger seat in their own stories, requiring them to record every moment, detail and sensation that is discovered. Revision presents the opportunity for writers to drive. Through careful reading and crucial choices of characters, scenes and details, writers navigate their narratives, maintaining the elements that serve the stories while letting go of those that don't. With advice from Robert Boswell's HalfKnown World, this writer demonstrates how revision makes the words go the distance. Freedom of Revision is a presentation that chronicles the journey of a story from the first draft to...

  15. ATP stimulation of volume regulation in cultured human astrocytoma cells


    Introduction: Understanding cell volume control of brain cells will lead to better treatments for patients suffering from brain edema following trauma and other conditions. We examined the role P2Y receptors play in cell volume regulation using cultured 1321Nl human astrocytoma cells. Methods: Cells were removed from the growth surface and suspended in isoosmotic phosphate buffered saline (Iso-PBS) containing (in mM): NaCI (147), KH2P04 (0.5), Na2HP04 (3.2), CaCI2 (1), MgCI2 (0.5), dextrose (5), and KCI (2.7) (pH=7.3, osmolality=290 mOsm) at 37°C for 30 min. Then, cell volumes were determined using the Coulter method at various times after cells were resuspended in...

  17. Localization of Autonomous Robotic Systems in Indoor Locations


    Autonomous robotic systems are becoming an integral part of the current and future commercial and military applications. Remote tracking, monitoring and navigation of these autonomous robotic systems in indoor environment are becoming more and more important. Global Positioning System (GPS), satellite based navigation system, plays a vital role in these applications. However, receiving satellite signals in indoor locations is a major problem. This problem can be overcome by using indoor localization systems like Cricket motes. Cricket is an inexpensive wireless sensor mote, which provides indoor localization of a given object. They have good accuracy, easy to configure and deploy. However,...
