Holy Ground: The Klezmatics Channel Woody Guthrie

Woody Guthrie’s personal connections to Judaism and Jewish culture began with his courtship and marriage to Marjorie Greenblatt Mazia, daughther of Yiddish writer Aliza Greenblatt, and blossomed when he and his family settled in Brooklyn’s Coney Island. Out of this Jewish connection came a rich body of songs eventually recorded by the New York-based Klezmer band, the Klezmatics. With concert performances and two albums of Guthrie songs — Woody Guthrie’s Happy Joyous Hanukkah and Wonder Wheel — the Klezmatics were instrumental in furthering Nora Guthrie’s project (begun with Billy Bragg and Wilco’s Mermaid Avenue releases) to expand the parameters within which Guthrie has been received. Concerned that biographers and folk music critics had placed too much emphasis on her father’s early Dust Bowl Ballads while downplaying his later songs, Nora Guthrie argued: “He was a poet and a lyricist that wrote about everything. I don’t want to see him turned into a freeze-dried, Dust Bowl icon representing a narrow version of what somebody thinks he was. These songs are just one more facet of his work that will add to a fuller picture of him as a songwriter.

Transient responses of three direct formulation injection systems for agricultural sprayers

Formulation injection into the spray diluent has many potential advantages, such as, less applicator exposure and improved application efficacy. However, there are some disadvantages associated with this technology that include formulation delivery delay time, inability to precisely deliver small amounts of formulation, and inadequate mixing of formulation into diluent Three types of formulation injection systems were observed to determine the transient performance of each system. An orifice-regulated system was designed and installed on a conventional sprayer. The orifice was calibrated under laboratory conditions before field efficacy tests were conducted. The efficacy of before pump and after pump injection sites were compared with a conventional tank-mix application at the same formulation rates. Commercially available, water-driven, piston-type injection unit(s) were tested in a three-branch system that provided variable system dilution rates using the fixed rate injection units. Two branches each contained an single water-driven injection unit while the third branch contained a throttling valve. Pressure transients from the pulsating units were of particular importance. Collected samples of nozzle discharge were measured for KBr concentration versus time. Flowrate through each branch was also measured. An experimental, variable-speed, diaphragm unit was designed and operated for at-the-nozzle injection. The unit\u27s flow was determined at different unit speeds and system pressures provided by an air back pressure arrangement. The unit also injected a KBr solution into an individual boom nozzle. The KBr solution was used as a tracer to determine the effects of diaphragm pulsation on nozzle discharge concentration uniformity versus time. The orifice-regulated system delay time and nozzle-to-nozzle variation were measured using a manual method of KBr sample collection. The water-driven units\u27 and the experimental unit\u27s injection performance was measured using a rotary sampler of nozzle discharge that increased sample frequency compared to the manual method. The rotary method collected 103 samples per one minute test duration. In the laboratory setup using a 5000 ppm KBr solution, the orifice-regulated system produced the desired formulation rate at the selected differential pressure [68.9 kPa (10 psi)] across the orifice for after pump injection. The differential pressure across the orifice for the before pump injection was affected by diluent pump suction, such that pressure supplied to the orifice had to be reduced by approximately 14-kPa (2-psi) to maintain the desired rate. In the field study applying Gramoxone Extra (paraquat dichloride) and Latron AG-98 spreader activator, the orifice-regulated direct injection system provided broadleaf and grass control ratings that ranged from 26 to 90 percent, as compared to the tank-mix system ratings that ranged from 82 to 90 percent. The lowest rating (26 percent) was possibly caused by an orifice that plugged after calibration, or due to incorrect pressure differential across the orifice. The orifice-regulated system provided direct injection capability with efficacy comparable to conventional application, especially at higher formulation rates, i.e. larger orifice size. No significant difference (a=0.05) in control ratings were observed between before pump and after pump injection sites and conventional tank-mix applications for the 2.43 L/ha (0.25 gal/ac) formulation application rate. The performance of the water-driven, piston pump unit varied based upon system branch selection, hose length configuration, and flowrate. The concept of using a bypass branch provided a potential method of varying KBr concentration by modulating flows through the bypass and the fixed-rate injection units. However, flow through the water-driven unit(s) was sensitive to adjustment of the bypass throttling valve due to the pressure loss [103 kPa (15 psi)] in the water-driven units. Dually-operated units did not generally lessen the intensity of the pressure pulse output, but rather tended to pulse simultaneously. The pressure measurements indicated this trend with individual water-driven unit operation variances that ranged from 71 kPa2 (1.5 psi2) to 361 kPa2 (7.6 psi2) compared to the range of dual unit variation from 532 kPa2 (11.2 psi2) to 4150 kPa2 (87.3 psi2). Pressure measurements showed no clear trend in variances between high and low system flowrates. Errors in KBr metering ranged from -57 to 26 percent and were attributed to KBr measurement accuracy, flowmeter accuracy, and the pumping efficiency of the water-driven unit at different flowrates. At higher flow rates, the water-driven units produced generally lower concentration variation (16 - 92 ppmi2) and generally improved KBr metering errors (-14 to 22.7%) compared to low flow KBr concentration variation (35 - 2037 ppmi2) and metering error (-57 - 26%). The additional hose length downstream from the combining cross increased the upstream pressure variance range [436 - 2001 kPa2 (9.2 - 42.1 psi2)] as compared to upstream pressure variance range [266 - 766 kPa2 (5.6 -16.1 psi2)] without the additional hose length. In contrast, the downstream pressure variance range [5 -1635 kPa2 (0.1 - 34.4 psi2)] with the additional hose length was less than the downstream pressure variance range [361 - 4474 kPa2 (7.6 - 94.1 psi2)] without the additional hose length. Thus, the water-driven unit needs the additional hose length to smooth the pressure spikes that are inherent to its operation. The asymmetrical setup of the branches had no smoothing effect upon system operating characteristics. The experimental-unit provided flowrates comparable to the rates required for injection at an individual nozzle. Specifically, the experimental unit produced flowrates for formulation application rates from 1.17 L/ha (0.125 gal/ac) to 4.68 L/ha (0.50 gal/ac) using a 6.4 km/h (4 mi/h) sprayer speed and 0.5 m (20 in) nozzle spacing. The experimental unit\u27s flowrate range was provided by a twelve-fold increase in unit speed. Operating speeds greater than 10 rpm are required to increase the uniformity of nozzle discharge concentration versus time

Victorian Material Culture in Memphis, Tennessee: The Mallory-Neely House Interiors As Artifact

The interiors of the Mallory-Neely House are valuable surviving documents of nineteenth century American culture warranting careful research, preservation and interpretation. Victorian Village, where the mansion is located in Memphis, is a nationally recognized enclave of nineteenth-century domestic structures. Previous research has centered primarily on the genealogical background of the owners and to a much lesser degree on the architectural history of these houses; none had focused in a scholarly manner on the interiors and furnishings. This is especially true of the Mallory-Neely House, the only one containing its original interior decor. These represent stratification of occupation and renovation by five families. Major phases of Victorian interior architectural treatment, changing approaches to interior decoration, and myriad Victorian furniture styles are represented. Due to an almost total lack of written documentation directly concerning the Mallory-Neely interiors, a material cultures methodological approach was used. Each of the interconnected ceremonial rooms was treated as an artifact. A system was developed in order to read” and gather data about each component of these interiors as well as the room ensemble as a whole. This information was then coupled with written evidence from various archival sources to form a base for interpretation. The artifacts comprising the Mallory-Neely interiors were found to be reflective of a society evolving towards modernization and representative of technological change. Dynamic change brought disruption of the social order and created a desire among Victorians for stabilizing symbols. The Mallory-Neely ceremonial interiors were created as a stage of status where symbolic social ritual was enacted. The interiors and their contents along with their closely related architectural and landscape surround visually communicated the owners\u27 elite status in the hierarchial class structure of the time
