    Notes: The earliest quantitative chemical analysis of ground water from the United States was probably made during 1807. The largest number of early analyses were of water from various mineral springs in and near the towns of Ballston and Saratoga Springs, New York. Although most of the scientific and economic interest at the time centered on the reported health benefits from the water, some of the earliest reports describing the springs contained rudimentary yet scientifically based hydrogeochemical explanations for the dissolved constitutents in the water. One motivation for the early analytical work was the desire to concoct a dry mixture of chemicals that would duplicate the mineral water when mixed with ordinary drinking water. The use of a powder would simplify distribution and bypass dealing with owners of the springs. Early analyses of water from Congress Spring published by different individuals between 1817 and 1856 are similar, and if allowance is made for minor temporal changes in quality, the results would be considered useful even by modern standards.

    Power Absorption During Microwave Heating of Emulsions and Layered Systems (1995)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 60 (1995), S. 0

    Notes: Microwave oven heating rates of various oil-in-water emulsions, water-in-oil emulsions, and layered systems were compared. Emulsions heated faster than corresponding layered systems, which heated faster than a calculated weighted average of individual components. Differences were attributed to increased power absorption caused by the large number of interfaces occurring in emulsions, or by a single interface in the layered system, and by resonant absorption of microwave radiation, which is determined by dielectric properties. The types and proportions of emulsions determined the number of interfaces. The dielectric properties and sample size determined in which samples resonant absorption occurred.

    Microwave-Heating Temperature Profiles for Thin Slabs Compared to Maxwell and Lambert Law Predictions (1995)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 60 (1995), S. 0

    Notes: Slabs of agar gel were heated in a microwave oven. Temperatures were measured at various depths into the sample to experimentally determine the internal temperature profile. These were compared to power and temperature profiles predicted from Lambert's law, Maxwell's field equations and a Combined equation. Lambert's law and the Combined equation predicted a much slower heating rate than found experimentally, while Maxwell's field equations gave a much more accurate prediction. Because of the internal standing waves that are created, a small variation in sample thickness could make a large difference in heating rate for thin samples.

    Reconciling Hadley Cell Expansion Trend Estimates in Reanalyses (2018)
    American Geophysical Union
    Details
    Publication Date: 2018-10-23
    Description: Numerous studies have concluded that historical Hadley cell expansion simulated in reanalyses is much larger than the future expansion predicted by climate model simulations. Is Hadley cell expansion too weak in climate models, or are the trends in reanalyses spuriously large? This study shows that the mean meridional circulation in reanalyses generally does not conserve mass. The mass imbalance projects onto trends in the Hadley cell edge latitudes by modifying both the mean and anomalous circulation. In correcting for the imbalance, the majority of Hadley cell expansion trends in early-generation reanalyses in both hemispheres are revised to be smaller in magnitude, bringing them into closer agreement with the trends in modern reanalyses and climate models. While the methodology presented here is statistical in nature, it produces quantitatively similar results to a more sophisticated mass budget correction method. ©2018. American Geophysical Union.

    Regional Widening of Tropical Overturning: Forced Change, Natural Variability, and Recent Trends (2019)
    American Geophysical Union
    Details
    Publication Date: 2019-06-20
    Description: The width of the tropical Hadley circulation (HC) has garnered intense interest in recent decades, owing to the emerging evidence for its expansion in observations and models and to the anticipated impacts on surface climate in its descending branches. To better clarify the causes and impacts of tropical widening, this work generalizes the zonal mean HC to the regional level by defining meridional overturning cells (RC) using the horizontally divergent wind. The edges of the RC are more closely connected to surface hydroclimate than more traditional metrics of regional tropical width (such as the sea level pressure ridge) or even than the zonal mean HC. Simulations reveal a robust weakening of the RC in response to greenhouse gas increases, along with a widening of the RC in some regions. For example, simulated widening of the zonal mean HC in the Southern Hemisphere appears to arise in large part from regional overturning anomalies over the Eastern Pacific, where there is no clear RC. Unforced interannual variability in the position of the zonal mean HC edge is associated with a more general regional widening. These distinct regional signatures suggest that the RCs may be well suited for the attribution of observed circulation trends. The spatial pattern of regional meridional overturning trends in reanalyses corresponds more closely to the pattern associated with unforced interannual variability than to the pattern associated with CO2 forcing, suggesting a large contribution of natural variability to the recent observed tropical widening trends. © 2019.

    Population Genetic Analyses of Transplanted Eelgrass (Zostera marina) Beds Reveal Reduced Genetic Diversity in Southern California (1996)

    Notes: Seagrass ecosystems fulfill ecologically and economically valuable functions in coastal marine environments. Unfortunately, seagrass beds are susceptible to natural and human disturbances, and their distrubution is declining worldwide. Although intentional disturbance of seagrass beds must be mitigated pursuant to U.S. law, to date mitigation of seagrass beds has not prevented a net loss of habitat. Transplantation of vegetative material from small areas of nearby beds is the primary method of seagrass mitigation. Restoration research on seagrasses has focused primarily on establishment of the plants and secondarily on the functional equivalency of the habitats. We questioned whether transplanted seagrass beds were comparable to “natural” beds in terms of genetic diversity and structure. We sampled Zostera marina L. (eel-grass) from 12 sites in the highly urbanized area of San Diego County and from pristine sites in Baja California. Using allozyme electrophoresis, we determined that genetic diversity (percentage of polymorphic loci, allele richness, expected and observed heterozygosities, and proportion of genetically unique individuals) was significantly reduced in transplanted eelgrass beds. Eelgrass from Baja California exhibited the highest genetic diversity. Based on Wright's F statistics, most of the genetic variation was distributed within rather than among sites (FST= 0.139), and the degree of genetic structure was only moderate at the greatest geographical scale (San Diego—Baja). Using a spatial statistical analysis (second-order analysis), we found virtually no evidence for nonrandom distribution of alleles or genotypes at scales of 3–50 m within beds. We discuss several hypotheses for reduced genetic diversity in transplanted eelgrass beds, including transplantation protocol, small size of transplantations, and reduced or failed sexual reproduction.

    Linking Policy and Outcomes: A Simulation Model of Poverty Incidence (1998)

    Notes: Many states are striving to meet public demand for accountability by “benchmarking”—setting social goals for the state and tracking progress in meeting the goals. However, states are finding it difficult to set realistic targets and to assess the impacts of policy on achievement of the targets without a framework that models the relationships among policy targets, policy actions and social and economic forces outside the control of policymakers. This paper develops a dynamic simulation model of one “benchmark” (poverty incidence) in Oregon, linking transitions into and out of poverty to various events (increased earnings, or having a child as a teenager, for example), and linking these events to policy. The simulation results suggest that, with current policies, Oregon will come close to achieving its poverty benchmark target of 11 percent by the year 2000 if economic conditions remain favorable. The model is used to examine the impact on poverty incidence of three policy strategies: reducing high school dropout and teen pregnancy rates, increasing the effectiveness of social support programs to JOBS participants, and boosting job growth. The simulation results suggest that when assessing the state's performance or “grading” the observed trend in the poverty benchmark, policymakers should take into account the performance of the state (and national) economy. The impact of policy efforts to reduce poverty is limited because many poverty spells are caused largely by events not affected by current state policies.
