Observation Of The Plasma Channel Dynamics And Coulomb Explosion In The Interaction Of A High-Intensity Laser Pulse With A He Gas Jet, G.S. Sarkisov, V. Yu. Bychenkov, V.T. Tikhonchuk, Anatoly Maksimchuk, Shouyuan Chen, R. Wagner, G. Mourou, Donald P. Umstadter

Donald Umstadter Publications

We report the first interferometric observations of the dynamics of electron–ion cavitation of relativistically self-focused intense 4 TW, 400 fs laser pulse in a He gas jet. The electron density in a channel 1 mm long and 30 mm in diameter drops by a factor of approximately 10 from the maximum value of ~8x10¹⁹ cm²³. A high radial velocity of the plasma expansion, ~3.8x10⁸ cm/s, corresponding to an ion energy of about 300 keV, is observed. The total energy of fast ions is estimated to be 6% of the laser pulse energy. The high-velocity radial plasma …

On The Strain-Rate Sensitivity Of Columnar Ice, M. E. Manley, E. M. Schulson

Dartmouth Scholarship

A power law relation between stress and strain rate of the form σ ∝ ε̇1/n was used to describe the response to strain rate of S1 ice loaded across the columns at -10°C. The rate exponent, n, decreased with increasing strain from about 4.6 at an observed peak on the load displacement curve to approximately 2.6 at a shortening of 2%. Analysis of these results and of the results of other authors on different forms of ice deformed at the same temperature suggests that the power law exponent, n, is proportional to Fc/Fg. The parameter Fc/Fg is the far-field basal …

Second Cause In Posterior Analytics Ii.11, Evelyn Barker

The Society for Ancient Greek Philosophy Newsletter

I contend that the second cause of Posterior Analytics II.11 expresses Aristotle's doctrine of material cause as hypothetical necessity in Physics II. Aristotle presents two formulations of the second cause in Posterior Analytics II. 11, which he "clearly" means to be equivalent. These two formulations of the second cause, taken literally without reference to the definition of the syllogism, fit Aristotle's description of a material cause being "hypothetical necessity" in Physics II - that is, a necessary means to produce a goal. In Physics II.9 Aristotle's thesis that an elementary mathematical definition is a "hypothetical necessity" for the proof of …

Some Problems In Estimating Finite Population Total And Variance In Survey Sampling., Saswati Bhattacharya Dr.

Doctoral Theses

The problem of drawing inference concerning the parameters of a finite population of identifiable units has been increasingly engaging the attention of statisticians. The central problem here is to devise a suitable method of selecting a sample from the population and to employ an appropriate estimator to estimate the finite population total or mean. A consider- able progress in this field of study has been made and many authors have contributed towards the development of the theory in this aspect of the problem of statistical inferenceNumerous papers have been written covering the first aspect of the problem, namely, method of …

Ramón López Velarde 1888–1921, J. Agustín Pastén B.

Spanish Language and Literature Papers

Modern Mexican poetry begins with Ramón López Velarde. He is undoubtedly one of the most genuine poetic voices to inhabit that hard-to-classify period in Spanish American literature that stretches from Modernism to the vanguard poets. As a major representative of Spanish American postmodernismo (that is, the period that followed Modernismo), he is the first writer in Mexico to thematize the Mexican province in a new way. But he ought not be reduced to being the poet of the province. López Velarde was above all the creator of a new poetic language; this alone distinguishes him from González Martínez, for example. …

Distributions Of Beryllium 7 And Lead 2109, And Soluble Aerosol-Associated Ionic Species Over The Western Pacific: Pem West B, February-March 1994, Jack E. Dibb, R. Talbot, Barry Lefer, Eric Scheuer, G L. Gregory, E V. Browell, J D. Bradshaw, S T. Sandholm, H B. Singh

Earth Sciences

Aerosol sampling for the determination of the concentrations of soluble ionic species and the natural radionuclides ⁷Be and ²¹⁰Pb was conducted from the NASA DC-8 over the western Pacific as part of GTE/PEM-West B during February-March 1994. Concentrations of most soluble ionic species in the free troposphere were higher in samples collected on flights originating from Hong Kong and Japan than those collected further east over the open ocean. In both regions the measured concentrations were higher than those found during PEM-West A (fall 1991). Activities of ²¹⁰Pb, a tracer of air masses influenced by sources on …

Comparisons Of Trace Constituents From Ground Stations And The Dc-8 Aircraft During Pem-West B, Richard Arimoto, R A. Duce, J M. Prospero, D L. Savoie, R. Talbot, Jack E. Dibb, B J. Heikes, B J. Ray, N F. Lewis, U Tomza

Earth Sciences

Chemical data from ground stations in Asia and the North Pacific are compared with data from the DC-8 aircraft collected during the Pacific Exploratory Measurements in the Western Pacific Ocean (PEM-West B) mission. Ground station sampling took place on Hong Kong, Taiwan, Okinawa, and Cheju; and at three Pacific islands, Shemya, Midway, and Oahu. Aircraft samples were collected during 19 flights, most over the western North Pacific. Aluminum was used as an indicator of mineral aerosol, and even though the aircraft did sample Asian dust, strong dust storms were not encountered. The frequency distribution for non-sea-salt sulfate (nss SO_{4 …}

Transport Of Sulfur Dioxide From The Asian Pacific Rim To The North Pacific Troposphere, D C. Thornton, A R. Bandy, Byrin W. Blomquist, R. Talbot, Jack E. Dibb

Earth Sciences

The NASA Pacific Exploratory Mission over the Western Pacific Ocean (PEM-West B) field experiment provided an opportunity to study sulfur dioxide (SO₂) in the troposphere over the western Pacific Ocean from the tropics to 60°N during February–March 1993. The large suite of chemical and physical measurements yielded a complex matrix in which to understand the distribution of sulfur dioxide over the western Pacific region. In contrast to the late summer period of Pacific Exploratory Mission-West A (PEM-West A) (1991) over this same area, SO₂showed little increase with altitude, and concentrations were much lower in the free …

Chemical Characteristics Of Continental Outflow From Asia To The Troposphere Over The Western Pacific Ocean During February-March 1994: Results From Pem-West B, R. Talbot, Jack E.

Bandy, R F. Pueschel

Earth Sciences

We present here the chemical composition of outflow from the Asian continent to the atmosphere over the western Pacific basin during the Pacific Exploratory Mission-West (PEM-West B) in February–March 1994. Comprehensive measurements of important tropospheric trace gases and aerosol particulate matter were performed from the NASA DC-8 airborne laboratory. Backward 5 day isentropic trajectories were used to partition the outflow from two major source regions: continental north (>20°N) and continental south (<20°N). Air parcels that had not passed over continental areas for the previous 5 days were classified as originating from an aged marine source. The trajectories and the chemistry together indicated that there was extensive rapid outflow of air parcels at altitudes below 5 km, while aged marine air was rarely encountered and only at <20°N latitude. The outflow at low altitudes had enhancements in common industrial solvent vapors such as C₂Cl₄, CH₃CCl₃, and C₆H₆, intermixed with the combustion emission products C₂H₂, C …

Large-Scale Distributions Of Tropospheric Nitric, Formic, And Acetic Acids Over The Western Pacific Basin During Wintertime, R. Talbot, Jack E. Dibb, Barry Lefer, Eric Scheuer, J D. Bradshaw, S T. Sandholm, S Smyth, D R. Blake, N J. Blake, G W. Sachse, J E. Collins Jr, G L. Gregory

Earth Sciences

We report here measurements of the acidic gases nitric (HNO₃), formic (HCOOH), and acetic (CH₃COOH) over the western Pacific basin during the February-March 1994 Pacific Exploratory Mission-West (PEM-West B). These data were obtained aboard the NASA DC-8 research aircraft as it flew missions in the altitude range of 0.3–12.5 km over equatorial regions near Guam and then further westward encompassing the entire Pacific Rim arc. Aged marine air over the equatorial Pacific generally exhibited mixing ratios of acidic gases <100 parts per trillion by volume (pptv). Near the Asian continent, discrete plumes encountered below 6 km altitude contained up to 8 parts per billion by volume (ppbv) HNO₃ and 10 ppbv HCOOH and CH₃COOH. Overall there was a general correlation between mixing …

A Detailed Comparison Of Hubble Space Telescopefaint Object Spectrograph Andiueultraviolet Spectra Of Selected Seyfert Nuclei, Anuradha Koratkar, Ian Evans, Sharon Pesto, Cynthia Taylor

Dartmouth Scholarship

Despite the contributions of the Hubble Space Telescope Faint Object Spectrograph (FOS) to the archive of UV observations of active galactic nuclei, the vast majority of UV reference data were obtained using the International Ultraviolet Explorer (IUE) satellite. These data remain important since they provide historical information about the intensities of the UV continua and emission lines that is needed to constrain models of the active nucleus. A detailed comparison of the FOS and IUE data is critical to understanding how the measurable quantities depend on the individual instrumental calibrations, and how any conclusions derived from modeling the …
