In order to use filth fly management simulation models that are driven by habitat temperatures, a mathematical relationship between manure temperature and air temperature, time of day, and manure depth was developed based on simultaneous hourly measurements of air and manure temperatures at depths of 1, 7, and 15 cm in three poultry housing environments over a three year period. Manure moisture had no measurable effect on manure temperature. A simulation model predicting population sizes of the house fly and a predaceous mite was driven using temperatures from the equation, and actual air and manure temperature recordings. Predicted population sizes using the estimated manure temperatures were closer to the sizes using actual manure temperatures than the sizes using air temperatures.

Median remission time of all dogs was 173 days. Remission duration was shorter, however, in dogs with stage IV/V disease, in dogs with pretreatment hypoalbuminemia, and in dogs that had received glucocorticoids before initiation of chemotherapy (P less than 0.04). Nineteen dogs were evaluable for toxicity. Dose-limiting gastrointestinal toxicosis was observed in three dogs, neutropenia was observed in three dogs, and cardiomyopathy was observed in three dogs. The doxorubicin/cyclophosphamide protocol described in this report is safe and effective in treating canine multicentric lymphosarcoma. Clinical stage, pretreatment steroid therapy, and hypoalbuminemia are prognostic factors for response to this protocol.

A DYNAMIC CASE AU - GHOSH, TK AU - PENG, H AU - BANKSLEE, P AU - HAMOUDA, H AU - SHIN, DH T2 - TEXTILE RESEARCH JOURNAL AB - The analysis of stress and displacement fields within a fabric roll is presented as a continuation of Part I of this series of papers. A discrete continuum model is used again to describe fabric deformation during the roll-making ( batching ) operation. The roll of fabric is considered to be in a state of plane stress, and the fabric is assumed to be anisotropic. The rotational speed of the fabric roll during the batching operation or the resultant fabric winding speed is considered as a parameter in the analysis. The effects of fabric winding speed on the state of stresses inside the roll is investigated, as is the problem of nonlinear lateral compressional behavior of the fabric.

The fabric elastic properties are assumed to be linear and anisotropic. Only the static case is considered, wherein dynamic effects in roll making are neglected. Effects of fabric Young's modulus in the warp and thickness directions, tube elastic modulus, fabric Poisson's ratios, and fabric weight per unit area on the state of stress inside the roll are parametrically investigated. Numerical results are obtained and discussed for each parameter. Theo retical results show that when a constant in-plane tension is applied for winding, the fabric may actually come under in-plane compression inside the roll. This observation is believed to be important, since it may reveal one of the causes of possible buckling and unevenness inside the roll. The theoretical model and the numercial solution procedures developed can easily be modified to incorporate nonlinear load-deformation behavior of fabrics.

At the six temperatures, respectively, the median development times (days) were for eggs: 25.5, 14.3, 7.4, 3.8, 3.5 and 3.5; for larvae 37.7, 20.9, 9.4, 6.0, 6.0 and 6.0; and for pupae 42.8, 33.6, 17.0, 9.7, 7.4 and 8.3. Maximum development rates for all stages were at 32.5°C. The percentage of survival at the six temperatures, respectively, for larvae were 66, 92, 98, 100, 93 and 93, and for pupae were 56, 86, 90, 100, 93 and 78. The parameters for the Sharpe and DeMichele (1977) temperature-dependent development model and the Stinner et al. (1975) distribution of development model were estimated from the constant temperature data and validated under a variable temperature cycle.

T2 - Evolution AB - -The genetic variance-covariance matrix, G, is determined in part by functional architecture, the pathways by which variation in genotype influences phenotype. I develop a simple architectural model for G for two traits under directional selection constrained by their dependence on a common limiting resource. I assume that genetic variance is maintained by mutation-selection balance. The relative numbers of loci that play a role in acquiring versus allocating a limiting resource play a crucial role in determining genetic covariance. If many loci are involved in acquiring a resource, genetic covariance may be either negative or positive at equilibrium, depending on the fitness function and the input of mutational variance. The form of G does not necessarily reveal the constraint on resource acquisition inherent in the system, and therefore studies estimating G do not test for the existence of life-history tradeoffs. Characters may evolve in patterns that are unpredictable from G. Experiments are suggested that would indicate if this model could explain observations of positive genetic covariance.

Recent improvements in the data analysis have led to a technique for determining and removing drift in the calibration such that the data at the end of the record are precise to ±1.3% (2σ) relative to the data at the beginning of the record. A statistical model, including terms for seasonal variation, linear trend, quasi‐biennial oscillation, solar cycle and second‐order autoregressive noise has been fit to the TOMS time series of total ozone data. The linear trend obtained when this statistical model is fit to the TOMS data averaged between 65N and 65S latitudes is −0.26±0.14%/year or −3% over the 11.6 year time period from November, 1978 through May, 1990. The trend is near zero (0.0002±0.2 %/year) at the equator and increases towards both poles. At 50N the annually averaged trend is −0.5±.21%/year. The 50N trend over the 11.6 year time period shows a strong seasonal variation from more than −0.8%/year in winter and early spring (February and March) to about −0.2%/year in summer (July and August).
