Much of the interannual variability in partially mixed estuaries in dissolved inorganic nutrient and dissolved oxygen patterns results from an enhancement or reduction of their annual cycle (generally via climatic forcing). In northern San Francisco Bay estuary the annual cycle of dissolved silicate supply peaks in spring and the effect of phytoplankton removal peaks in fall. Because riverine silicate sources are enhanced in wet years and reduced in dry years, the annual silicate cycle is modified accordingly. Effects of phytoplankton removal are reduced and delayed in wet years and enhanced and advanced (seen earlier) in dry years. Similar reasoning can apply to interpreting and understanding other mechanisms and rates.

A molecular orbital description, based on spin-unrestricted Xα-scattered wave calculations, is given for the electronic structures of mixed valence iron oxides and silicates. The cluster calculations show that electron hopping and optical intervalence charge-transger result from weak FeFe bonding across shared edges of FeO6 coordination polyhedra. In agreement with Zener's double exchange model, FeFe bonding is found to stabilize ferromagnetic coupling between Fe2+ and Fe3+ cations.

The amount of wetland habitat influenced productivity primarily by affecting the renesting rate. Late snowstorms severely reduced productivity, whereas the loss of nests due to flooding was largely compensated for by increased renesting, often in habitats where hatching rates were better.

In decades past, the rancher depended upon reports from cowboys to gather information he needed to make management decisions. Today, the vast open ranges of the cowboy era are mostly gone in the United States-fenced into pastures, paddocks, or fields that are now discrete management units. But fencing in the rangeland, while it has replaced much of the need for cowboys, has not replaced the need for information about the health and vigor of the forage on each parcel of land. Can a satellite, orbiting at more than 400 miles in space, serve this purpose? As ranchers and resource specialists are asked to make more and more complex management decisions, with less manpower for conducting inventories, they are wise to seek help in today's rapidly developing technologies. For the past few decades the range technician has accomplished most of his range assessment from a pickup truck, traveling periodically to each unit to determine its status. Now, satellite images of the Earth's resources might be able to help the modern range person do an even more efficient job of monitoring the availability of feed for livestock and wildlife. Yet some important questions need to be answered first. Can this new information source be used to evaluate the ecological condition of these lands? Or are satellite images of our Earth and its variety of landscapes just \"pretty pictures,\" with little practical utility?

In June 1984, fry of Atlantic salmon, Salmo salar L., (0-3 g mean weight), being reared in a hatehery operated by the University of Washington, began to die and infectious haematopoietic necrosis (IHN) was diagnosed. A total of 40 000 fry were being held in 11 tanks. Mortality due to IHN was noticeable in three tanks, losses being heavy in one and moderate in two. Gross examination of the fish failed to reveal an obvious cause of death. Signs included: evidence of haemorrhage ventrally, anterior to the anus; pale gills and liver; an empty gut, except for the presence of a white caseous material; and abdominal distension. The spleen and kidney were normal. When examinations of the fish for bacteria and parasites were negative, virus isolation was attempted.

An experimental computer-generated shaded-relief map of a topographic quadrangle of Nome, Alaska, at 1:1,000,000 scale was created to demonstrate current capabilities of map production. This paper describes the techniques used to produce the map product.

\n

The data consisted of forty-eight 1° by 1° blocks of resampled digital elevation model (DEM) data. These data were digitally mosaicked and assigned colors based on intervals of elevation values. The color-coded data set was then used to create a shaded-relief image that was photographically composited with cartographic line information to produce a shaded-relief map. The majority of the processing was completed at the National Mapping Division EROS Data Center in Sioux Falls, South Dakota.

Multiple-regression analyses, in progress, are being refined to determine the best regression models for each of the storm-runoff constituent loads in each of the three regions. These techniques, when finalized, can be used to estimate storm-runoff constituent loads for gaged and ungaged urban watersheds. The preliminary standard errors of estimate for five constituents examined to date ranged from 54 to 223 percent, and the coefficients of determination (r**2) ranged from 0. 39 to 0. 94. Total storm rainfall and total contributing drainage area appear to be the most significant independent variables in the regression models. This paper is a progress report on preliminary results of estimating storm-runoff constituent loads for ungaged watersheds.","conferenceTitle":"Urban Runoff Quality - Impact and Quality Enhancement Technology, Proceedings of an Engineering Foundation Conference.","conferenceLocation":"Henniker, NH, USA","language":"English","publisher":"ASCE","publisherLocation":"New York, NY, USA","isbn":"087262577X","usgsCitation":"Driver, N.E., and Lystrom, D.J., 1986, ESTIMATION OF URBAN STORM-RUNOFF LOADS., Urban Runoff Quality - Impact and Quality Enhancement Technology, Proceedings of an Engineering Foundation Conference., Henniker, NH, USA, p. 122-132.","startPage":"122","endPage":"132","numberOfPages":"11","costCenters":[],"links":[{"id":226225,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0469e4b0c8380cd5097d","contributors":{"editors":[{"text":"Urbonas BenRoesner Larry A.","contributorId":128383,"corporation":true,"usgs":false,"organization":"Urbonas BenRoesner Larry A.","id":536288,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Driver, Nancy E.","contributorId":67858,"corporation":false,"usgs":true,"family":"Driver","given":"Nancy","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":368498,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lystrom, David J.","contributorId":101283,"corporation":false,"usgs":true,"family":"Lystrom","given":"David","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":368499,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70186152,"text":"70186152 - 1986 - Application of the Flory-Huggins theory to the solubility of solids in glyceryl trioleate","interactions":[],"lastModifiedDate":"2020-01-18T11:13:37","indexId":"70186152","displayToPublicDate":"1986-01-01T00:00:00","publicationYear":"1986","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":5353,"text":"Journal of the Chemical Society, Faraday Transactions I","active":true,"publicationSubtype":{"id":10}},"title":"Application of the Flory-Huggins theory to the solubility of solids in glyceryl trioleate","docAbstract":"

The conventional thermodynamic deviation for ideal solid–liquid solubilities is modified by substituting the Flory–Huggins model for Raoult's law. A comparison of published data for eleven solides in glyceryl trioleate with the predictions of the conventional and modified equations shows that the significantly higher athermal solubilities from the modified equation are in much better agreement with the experimental data. This suggests that discrepancies between the data and the predictions of the conventional model for ideal systems result from the inappropriate use of Raoult's law for systems with significant solute–solvent size disparity rather than from specific interactions.

Miscible displacement techniques were used to create Cl- concentration profiles in unsaturated laboratory columns of Delhi sand (Typic Xeropsamments), each having a nearly uniform water content. The three steady flow rates used resulted in three different, average water contents. Chloride concentrations near the top of the column were smaller and penetration of Cl- in the column was deeper than expected assuming that Cl- is a noninteracting solute. Such observations indicate the presence of anion exclusion. This interpretation is further substantiated by chloride and tritium breakthrough curves obtained from a saturated column of the same soil. The saturated experiments show that tritium occupies the entire measured pore volume of the column, but that Cl- is restricted to a smaller pore volume. The formulation of the conventional convection-dispersion theory for solute transport in soil which includes anion exclusion resulted in model calculations that fitted the unsaturated Cl- concentration profiles quite well. The dispersion coefficients obtained for the unsaturated profiles increase with water velocity and are lower than those previously reported for comparable water velocities in the same but saturated soil. The dispersivity of the unsaturated soil is also smaller than that reported for the saturated soil. For the experimental conditions used, the effective Cl- exclusion volume was found to be independent of water content and velocity and occupied about ten percent of the unsaturated water content.

Denitrification in aquatic sediments was measured by an N2O reductase assay. Sediments consumed small added quantities of N2O over short periods (a few hours). In experiments with sediment slurries, N2O reductase activity was inhibited by O2, C2H2, heat treatment, and by high levels of nitrate (1 mM) or sulfide (10 mM). However, ambient levels of nitrate (<100 μM) did not influence activity, and moderate levels (about 150 μM) induced only a short lag before reductase activity began. Moderate levels of sulfide (<1 mM) had no effect on N2O reductase activity. Nitrous oxide reductase displayed Michaelis-Menten kinetics in sediments from freshwater (Km = 2.17 μM), estuarine (Km = 14.5 μM), and alkaline-saline (Km = 501 μM) environments. An in situ assay was devised in which a solution of N2O was injected into sealed glass cores containing intact sediment. Two estimates of net rates of denitrification in San Francisco Bay under approximated in situ conditions were 0.009 and 0.041 mmol of N2O per m2 per h. Addition of chlorate to inhibit denitrification in these intact-core experiments (to estimate gross rates of N2O consumption) resulted in approximately a 14% upward revision of estimates of net rates. These results were comparable to an in situ estimate of 0.022 mmol of N2O per m2 per h made with the acetylene block assay.

A hazard assessment scheme was developed and applied to predict potential harm to aquatic biota of nearly 500 organic compounds detected by gas chromatography/mass spectrometry (GC/MS) in Great Lakes fish. The frequency of occurrence and estimated concentrations of compounds found in lake trout (Salvelinus namaycush) and walleyes (Stizostedion vitreum vitreum) were compared with available manufacturing and discharge information. Bioconcentration potential of the compounds was estimated from available data or from calculations of quantitative structure-activity relationships (QSAR). Investigators at the National Fisheries Research Center-Great Lakes also measured the acute toxicity (48-h EC50's) of 35 representative compounds to Daphnia pulex and compared the results with acute toxicity values generated by QSAR. The QSAR-derived toxicities for several chemicals underestimated the actual acute toxicity by one or more orders of magnitude. A multiple regression of log EC50 on log water solubility and molecular volume proved to be a useful predictive model. Additional models providing insight into toxicity incorporate solvatochromic parameters that measure dipolarity/polarizability, hydrogen bond acceptor basicity, and hydrogen bond donor acidity of the solute (toxicant).

The effects of a flood-control reservoir on downstream macroinvertebrates were assessed by comparing the tailwater community with that of a natural stream. Samples were collected 1.6 and 21.1 km below Barren River Lake dam in 1979, 1980, and 1981 and in a reservoir tributary in 1980 and 1981. An indication of environmental stress in the macroinvertebrate community was observed at both tailwater stations, whereas macroinvertebrates in the natural tributary stream had the characteristics commonly associated with a ‘healthy’ community. Densities of macroinvertebrates in tailwaters were highest during periods of low-stable flows and lowest during fluctuating and high-stable flows. Changes in temperature cycles and water quality were also considered factors in reducing macroinvertebrate abundance in the tailwater. Dominant macroinvertebrate taxa in tailwaters were primarily small organisms with a high tolerance for dynamic living conditions. Of these, aquatic Diptera, Oligochaeta, Caenis, Cheumatopsyche, and Planariidae were most common. The effects of reservoir discharge were most evident near the dam, where macroinvertebrate densities were relatively high and taxonomic diversity was low. Downstream, the impact of the reservoir was moderated, but recovery was judged incomplete.

Linear correlation of the logarithmic capacity factor (k') with the number of carbons in the alkyl chain provides useful information on both gas chromatographic (GC) and high-performance liquid chromatographich (HPLC) retention parameters of unknown components. Under all conditions empolyed, GC methodology has proved effective in achieving complete resolution of the homologous mixture of NMA despite its obvious inadequacy in the separation of E-Z configurational isomers. Conversely, normal-phase HPLC on silica demonstrates that the selectivity (a) value for an E-Z pair is much higher than that for an adjacent homologous pair. In the reversed-phase HPLC study, three different silica-based column systems were examined under various mobile phase conditions. The extent of variation in k' was found to be a function of the organic modifier, counter-ion concentration, eluent pH, nature of counter-ion, and the polarity and type of stationary phase. The k'—[NaClO4] profiles showed similar trends between the ABDAC and the NAMA series, supporting the dipolar electronic structures of the latter compounds. Mobile phase and stationary phase effects on component separation are described. The methodology presented establishes the utility of HPLC separation techniques as versatile analytical tools for practical application.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Chromatography","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/S0021-9673(01)81321-2","collaboration":"None","usgsCitation":"Abidi, S.L., 1985, Retention behavior of long chain quaternary ammonium homologues and related nitroso-alkymethylamines: Journal of Chromatography, v. 324, no. 2, p. 209-230, https://doi.org/10.1016/S0021-9673(01)81321-2.","productDescription":"22 p.","startPage":"209","endPage":"230","numberOfPages":"22","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":258848,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":258845,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0021-9673(01)81321-2","linkFileType":{"id":5,"text":"html"}}],"volume":"324","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aac06e4b0c8380cd86af7","contributors":{"authors":[{"text":"Abidi, S.

Management was formulated in the context of optimal stochastic control theory, with objective functions composed of discounted or time-averaged biomass yields. Climatic variability and community patterns of salt desert shrublands make the application of stochastic optimal control both feasible and necessary. A primary production model was used to simulate shrub responses and harvest yields under a variety of climatic regimes and defoliation patterns. The simulation results then were used in an optimization model to determine optimal defoliation strategies. The latter model encodes an algorithm for finite state, finite action, infinite discrete time horizon Markov decision processes. Three questions were addressed: (i) What effect do changes in weather patterns have on optimal management strategies? (ii) What effect does the discounting of future returns have? (iii) How do the optimal strategies perform relative to certain fixed defoliation strategies? An analysis was performed for the three shrub species, winterfat (Ceratoides lanata), shadscale (Atriplex confertifolia) and big sagebrush (Artemisia tridentata). In general, the results indicate substantial differences among species in optimal control strategies, which are associated with differences in physiological and morphological characteristics. Optimal policies for big sagebrush varied less with variation in climate, reserve levels and discount rates than did either shadscale or winterfat. This was attributed primarily to the overwintering of photosynthetically active tissue and to metabolic activity early in the growing season. Optimal defoliation of shadscale and winterfat generally was more responsive to differences in plant vigor and climate, reflecting the sensitivity of these species to utilization and replenishment of carbohydrate reserves. Similarities could be seen in the influence of both the discount rate and the climatic patterns on optimal harvest strategics. In general, decreases in either the discount rate or in the frequency of favorable weather patterns lcd to a more conservative defoliation policy. This did not hold, however, for plants in states of low vigor. Optimal control for shadscale and winterfat tended to stabilize on a policy of heavy defoliation stress, followed by one or more seasons of rest. Big sagebrush required a policy of heavy summer defoliation when sufficient active shoot material is present at the beginning of the growing season. The comparison of fixed and optimal strategies indicated considerable improvement in defoliation yields when optimal strategies are followed. The superior performance was attributable to increased defoliation of plants in states of high vigor. Improvements were found for both discounted and undiscounted yields.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Environmental Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Williams, B.K., 1985, Optimal management strategies in variable environments: Stochastic optimal control methods: Journal of Environmental Management, v. 21, no. 1, p. 95-115.","productDescription":"95-115","startPage":"95","endPage":"115","numberOfPages":"21","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":196089,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0de4b07f02db5fd29f","contributors":{"authors":[{"text":"Williams, B.

Some meadow vole capture-recapture data are used to illustrate the testing procedure which has been implemented in a computer program available from the authors.","language":"English","publisher":"International Biometric Society","doi":"10.2307/2530865","usgsCitation":"Pollock, K.H., Hines, J., and Nichols, J., 1985, Goodness-of-fit tests for open capture-recapture models: Biometrics, v. 41, no. 2, p. 399-410, https://doi.org/10.2307/2530865.","productDescription":"12 p.","startPage":"399","endPage":"410","numberOfPages":"12","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":196858,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"41","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abde4b07f02db674071","contributors":{"authors":[{"text":"Pollock, K.
