Survival Of Escherichia-Coli And Salmonella Spp In Estuarine Environments, Mw Rhodes, Hi Kator

VIMS Articles

Survival of Escherichia coli and Salmonella spp. in estuarine waters was compared over a variety of seasonal temperatures during in situ exposure in diffusion chambers. Sublethal stress was measured by both selective-versus-resuscitative enumeration procedures and an electrochemical detection method. E. coli and Salmonella spp. test suspensions, prepared to minimize sublethal injury, were exposed in a shallow tidal creek and at a site 7.1 km further downriver. Bacterial die-off and sublethal stress in filtered estuarine water were inversely related to water temperature. Salmonella spp. populations exhibited significantly less die-off and stress than did E. coli at water temperatures of <10°C. Although the most pronounced reductions (ca. 3 log units) in test bacteria occurred during seasonally warm temperatures in the presence of the autochthonous microbiota, 102 to 104 test cells per ml remained after 2 weeks of exposure to temperatures of >15°C. Reductions …

Discocilia And Paddle Cilia In The Larvae Of Mulinia Lateralis And Spisula Solidissima (Mollusca: Bivalvia), Bernardita Campos, Roger L. Mann

VIMS Articles

The bivalve larval velum contains four bands of cilia: inner and outer preoral bands, an adoral band, and a postoral band. The preoral bands of compound cilia are generally considered to be used for both locomotion and food gathering. The adoral and postoral bands function in concert with the preoral bands in food gathering and transfer of food to the mouth. Cilia are usually described as cylindrical structures which taper to a blunt tip. Modified cilia with disc-shaped (discocilia) or pad dle-shaped ends have been recorded in several invertebrate species. Here, for the first time, we demonstrate the presence of …

Subprocedure Anti-Appendectomies, Judi Harris

School of Education Articles

Logo novices may be hesitant to write procedures that should be stored in memory and invoked with a single command. The leap from immediate mode doodling to preplanned, hierarchically structured procedure writing can be a large one. It is possible to bridge those two experiences with a simple Logo tool called APPEND.

Oyster Spatfall In Virginia Rivers: 1988 Annual Summary, Bruce Barber, James Whitcomb

Reports

The Virginia Institute of Marine Science (VIMS) conducts annual surveys of oyster spatfall ( or "sett.ing") in Virginia waters. This survey provides an estimate of the potential of a particular area for receiving a "striken or set of oysters and helps define the timiug of setting events. In 1988 spatfall was monitored from June 6 to October 16 at a total of forty-two stations (Figure 1). · During this period shellstrings were deployed at each station (0.5m off the bottom) on a weekly basis. A shellstring consists of 12 oyster shells drilled through the center and strung on a piece …

Swinburne's Speech To The Royal Literary Fund, May 2, 1866, Terry L. Meyers

Arts & Sciences Articles

" Algernon Charles Swinburne made so few formal presentations to any kind of audience that only a single public one, so far as I know, is recorded- his reply to a toast at the Royal Literary Fund Dinner of May 2, 1866.' Scholars have thought they had no access to the speech, for, although Edmund Gosse prints a part of it in his biography of Swinburne (along with a slightly distorted account of its presentation) and other biographers include other bits and pieces, it has, to all intents and purposes, dropped from sight; only those able to see the papers …

Reports

Deployment : The tripods were assembled, tested and secured onboard the RIV Sea Diver, which left the Little Creek Amphibious Base in Norfolk, Virginia early on 26 September. While underway to the deployment site, the continuous surface water conductivity and temperature survey was run and several CTD casts were made. The tripods were deployed on 26 September and secured to the sea floor with sand anchors by VIMS divers. The R/V Sea Diver then began the series of on/off shore transects at the tripod deployment site for approximately 12 hours. The vessel returned to port on 27 September .

The Stranger, The Better, Judi Harris

School of Education Articles

In 1968, Synectics, Inc, an independent educational research group, published an excellent set of classroom materials that encouraged the conscious use of metaphor to stimulate creative thinking and, subsequently, original writing. With a few simple Logo procedures, your students can generate individualized metaphors to inspire their creative writing. And unlike consumable instructional supplies, this type of Logo output is rarely repetitive and never exhausted.

Secular Conversions, Judi Harris

School of Education Articles

Your students, no doubt, have long since realized that Logo is not the first-string choice for effecting graphic realism. But, now and again, identifiable pictures are needed for Logo programs. Somehow, stick figures can bely the sophistication of the code by which they appear, not to mention that a turtled drawing of even moderate detail can take eons to manifest in full geometric splendor. This article discusses "Logo LinX".

Experimental Studies Of Zinc-65 Uptake Rates By The American Oyster, Crassostrea Virginica With Regard To Salinity, Sediment Concentration, And Body Size, Cheol Mo, Bruce Neilson

Reports

Three sets of twelve oysters from the ,James River were placed in three recirculating aquaria dosed with the radioactive tracer zinc-65. All aquaria had the same amount of river bottom sediment which was kept in suspension by the water movement caused by aeration; one aquarium had twice as much tracer as the other two. The salinity of one of the low dose aquaria and. the high dose aquarium was maintained at 18 0/00: the other low dose aquarium was maintained at 1:2 0/00. All other factors were kept constant. Sediment-water-tracer mix was added to the aquaria every 12 hours. Water …

Effect Of Closed Classical Orbits On Quantum Spectra: Ionization Of Atoms In A Magnetic Field. I. Physical Picture And Calculations, M. L. Du, John B. Delos

Arts & Sciences Articles

This is the first of two papers that develop the theory of oscillatory spectra. When an atom is placed in a magnetic field, and the absorption spectrum into states close to the ionization threshold is measured at finite resolution, so that individual energy levels are not resolved, it is found that the absorption as a function of energy is a superposition of sinusoidal oscillations. These papers present a quantitative theory of this phenomenon. In this first paper, we describe the physical ideas underlying the theory in the simplest possible way, and we present our first calculations based upon the theory. …

Comparison Of Condition Indicies (K) Of Spot (Leiostomus Xanthurus) From The Elizabeth And York Rivers, Virginia, Kinloch Nelson

Reports

Spot from the York and Elizabeth Rivers were taken in 1983, 1984, and 1985. The length to weight ratio was used to find the equation for Condition Index (K). Condition Indices for the two populations were found and plotted against temperature. Regression lines were plotted for each group. From 6 to 19 degrees, the Condition Index of the two populations rises at similar rates. From 19 degrees on, the Elizabeth River Condition Index rises steadily while the York K drops down to approach the levels of winter.

Effect Of Closed Classical Orbits On Quantum Spectra: Ionization Of Atoms In A Magnetic Field. Ii. Derivation Of Formulas, M. L. Du, John B. Delos

Arts & Sciences Articles

A formula is derived for oscillations in the near-threshold absorption spectrum of an atom in a magnetic field. Three approximations are used. (1) Near the atomic nucleus, the diamagnetic field is negligible. (2) Far from the nucleus, the waves propagate semiclassically. (3) Returning waves are similar to (cylindrically modified) Coulomb-scattering waves. With use of these approximations, together with the physical picture described in the accompanying paper, an algorithm is specified for calculation of the spectrum.

Atomic Electrons In Strong Magnetic Fields: Transition From Elliptical To Helical Behavior., John B. Delos, Stephen Knudson, Shena Sikora, Robert Leonard Waterland, S. Whitworth

Arts & Sciences Articles

The behavior of an atomic electron in a static magnetic field strong enough to correspond to the transition regime is examined. The field strength is characterized by the parameter L^, the effective component of angular momentum. A Floquet-Mathieu analysis shows that the bifurcation of classical trajectories into elliptical and helical families is related to the 2:1 resonance which occurs at L^=L^T. Quantum mechanics gives an avoided crossing at L^T; we examine the nature of the wave functions as L^ passes through the resonance. Semiclassical calculations accurately reproduce the quantum eigenvalues and produce trajectories which underlie the quantum wave functions. …
