Photoacoustic And Nephelometric Spectroscopy Of Aerosol Optical Properties With A Supercontinuum Light Source, Neha Sharma, I. J. Arnold, H. Moosmüller, W. P. Arnott, C. Mazzoleni

Michigan Tech Publications, Part 1

A novel multi-wavelength photoacousticnephelometer spectrometer (SC-PNS) has been developed for the optical characterization of atmospheric aerosol particles. This instrument integrates a white light supercontinuum laser with photoacoustic and nephelometric spectroscopy to measure aerosol absorption and scattering coefficients at five wavelength bands (centered at 417, 475, 542, 607, and 675 nm). These wavelength bands are selected from the continuous spectrum of the laser (ranging from 400-2200 nm) using a set of optical interference filters. Absorption and scattering measurements on laboratory-generated aerosol samples were performed sequentially at each wavelength band. To test the instrument we measured the wavelength dependence of absorption and …

Rf Transport Electromagnetic Properties Of Graphene From Dc To 110 Mhz, Sa Awan, G Pan, Taan Lm Al, B Li

School of Engineering, Computing and Mathematics

The paper describes measurement of RF transport electromagnetic properties of CVD graphene over the DC to 110 MHz frequency range at room temperature. Graphene on Si/SiO2 substrate was mounted in a shielded four terminal-pair (4TP) adaptor which enabled direct connection to a calibrated precision impedance analyser for measurements. Good agreement is observed for the DC four-probe resistance and the 4TP resistance at 40 Hz, both yielding R ~104 Ohms. In general the apparent graphene channel electromagnetic properties are found to be strongly influenced by quantum contact effects, such as resistance and capacitance, particularly at DC and low frequencies f < 1 MHz. A phenomenological lumped-parameter equivalent circuit model is presented which matches the frequency response of the graphene 4TP impedance device over approximately seven decades of the frequency range of the applied transport alternating current. Based on this model, the intrinsic graphene channel resistance is found to be RG = 2.2 Ohms or sheet resistance of 3.85 Ohms/sq, which is frequency independent, with each contact impedance being RC = 51.6 Ohms and CC = 1.2 nF. These results suggest that our RF 4TP method may be more accurate and reliable than the conventional DC four-probe method for measuring the intrinsic sheet resistance of single-atom thick materials such as graphene. This may be significant for the production and optimisation of graphene for solar-cells and touch-screen displays where sheet resistance (combined with its optical transparency) figures-of-merit play an important role, particularly in comparison with the values of the current material of choice, indium tin oxide (ITO), for such applications.

Growing Things "Rare, Foreign, And Tender": The Early Nineteenth-Century Greenhouse At Gore Place, Waltham Massachusetts, Christa M. Beranek, J. N. Leith Smith, John M. Steinberg, Michelle G. S. Garman

Northeast Historical Archaeology

Excavations and ground penetrating radar at Gore Place in Waltham, Massachusetts, uncovered part of an early 19th-century greenhouse (ca. 1806 to the early 1840s) constructed by Christopher and Rebecca Gore. Documentary, archaeological, and geophysical data suggest that the greenhouse was a formal space intended to display exotic plants and that it was built in the relatively new lean-to style, with a tall back wall and a short front wall. The artifact assemblage included tools and small finds related to the greenhouse operation, as well as the remains of at least 149 planting pots. The greenhouse was constructed during a period …

The Mother Of The Father Of Our Country: Mary Ball Washington's Genteel Domestic Habits, Laura J. Galke

Northeast Historical Archaeology

The year 1743 brought hardship to the Washingtons as their family patriarch, Augustine, passed away unexpectedly. At that time, a young George Washington inherited the family’s home plantation in Fredericksburg, known today as Ferry Farm. Augustine’s will stipulated that George’s mother, Mary Ball Washington, manage the plantations of their four young boys until they came of age. Between 1743 and 1772, Mary enjoyed the personal agency that widowhood allowed her; she was responsible for the management decisions of the Washington household and the surrounding farm. Mary’s choices reflect an ambitious woman determined to participate in the genteel society her family …

The Role Of Culture In Image Restoration: A Cross-Cultural Analysis Of The Strategies Used By John Edwards And Dominique Strauss-Khan, Isabel Artime

Open Access Theses

Image has become a commodity, an essential asset to both individuals and organizations. When image is threatened, we are compelled to do repair work to help us save face. In the 1990s, William Benoit developed an encompassing theory of image restoration, guiding us through the different options available to organizations and individuals involved in a crisis. However, the study of image restoration has traditionally remained highly ethnocentric, focused on Western culture and assuming that individuals and organizations respond to crises in similar ways, regardless of the particular aspects of the culture to which they belong. This study applies Hofstede's model …

Sensory Basis For Detection Of Benthic Prey In Two Lake Malawi Cichlids., Margot A. B. Schwalbe, Jacqueline F. Webb

Biological Sciences Faculty Publications

The adaptive radiations of African cichlids resulted in a diversity of feeding morphologies and strategies, but the role of sensory biology in prey detection and feeding ecology remains largely unexplored. Two endemic Lake Malawi cichlid genera, Tramitichromis and Aulonocara, feed on benthic invertebrates, but differ in lateral line morphology (narrow and widened lateral line canals, respectively) and foraging strategy. The hypothesis that they use their lateral line systems differently was tested by looking at the relative contribution of the lateral line system and vision in prey detection by Tramitichromis sp. and comparing results to those from a complementary study using …

Genetic Sex Conditions And Redefining Sex, Jayce O'Shields

Student Scholarship

Western culture has a tendency to value binaries and discreet categories that separate its social structure and provide a sense of order and organization. The value placed on binaries and categories may be advantageous in some aspects, but when it starts to infringe upon the legal and medical rights of individuals not easily placed in either binary category, it can become less advantageous.

A baby is usually classified as either male or female shortly after birth, and all future legal, social, and economic actions and rights of that individual are more or less decided according to this classification. A problem …

Limit For Thermal Transport Reduction In Si Nanowires With Nanoengineered Corrugations, Sean E. Sullivan, Keng-Hua Lin, Stanislav Avdoshenko, Alejandro Strachan

Birck and NCN Publications

Non-equilibrium molecular dynamics simulations reveal that the thermal conductance of Si nanowires with periodic corrugations is lower than that of smooth wires with cross-sections equivalent to the constricted portions. This reduction in conductance is up to 30% and tends to plateau with increasing corrugation height. Spatially resolved temperature and heat current maps provide a microscopic understanding of this effect; we find that 80% of the heat current is carried through the constricted area even for high-amplitude corrugations. More importantly, we show that temperature gradient inversion and heat current vortices at the ridge peaks establish fundamental limits on maximum conductance reduction. …

Polarization Diversity In The Presence Of Multipath Propagation, Grant Taylor Wagner

Theses and Dissertations

The possibility of polarization diversity using left and right hand circular polarization (LHCP and RHCP) in the presence of multipath propagation is examined. We show that there are differences in the received signal for LHCP and RHCP for a number of realistic scenarios. Because multipath propagation can produce different LHCP and RCHP signals, there exists the possibility for diversity improvement involving the two polarizations.

Digital Outcrop Model And Paleoecology Of The Eight-Foot Rapid Algal Field (Middle Pennsylvanian Lower Ismay Sequence), Paradox Basin, Utah, Colton Lynn Goodrich

Theses and Dissertations

Although phylloid algal mounds have been studied for 50 year, much remains to be determined concerning the ecology and sedimentology of these Late Paleozoic carbonate buildups. Herein we perform a digital outcrop study of the well-known Middle Pennsylvanian Lower Ismay mound interval in the Paradox Basin because outcropping mounds along the San Juan River are cited as outcrop analogs of reservoir carbonates in the Paradox Basin oil province of Utah and adjacent states. The principal field area is the Eight Foot algal field located at river mile 19.2 on the San Juan River, approximately 14 miles SSW of Bluff, Utah. …
