Results of a fish health survey of North Biscayne Bay, June 1976-June 1977

Fish were collected weekly in Biscayne Bay using a monofilament gill net set from a small skiff during 20-30 minute intervals. Although weekly sampling took place for 2.5 years, only the data from samples collected from June 1976 to June 1977 were used in this document. Abnormal external conditions of fins and body were observed on each fish and recorded. Fish were returned immediately to their habitats. Fish collected in the time period for this study numbered 3,765 and included 32 species. Of these, 16 species, totaling 3,556 fish, were caught in sufficient numbers (20 or more) to warrant data analysis. Only 3 of the 16 species could be considered relatively unafflicted: Aetobatus narinari (spotted eagle ray), Diodon hystrix (porcupinefish), and Selene vomer (lookdown). More than 80% of the examined specimens of these three species were unaffected. Less than 20% of the specimens of Diapterus plumieri (striped mojarra), Micropogonias undulatus (Atlantic croaker), and Pogonias cromis (black drum) displayed normal conditions. The three most afflicted species were Diapterus plumieri, striped mojarra; Micropogonias undulatus, Atlantic croaker; and Pogonias cromis, black drum. Only 7, 3, and 7% respectively showed no external evidence of disease. Data described in this document were originally tabulated in the mid-1970s, remained unpublished, and are no longer available. This document was based on archived unpublished text, a data summary table, and figures. Most of the text and cited references were the ones used in the original manuscript and no attempt was made to update them. (PDF contains 44 pages

Utilizing remote sensing of Thematic Mapper data to improve our understanding of estuarine processes and their influence on the productivity of estuarine-dependent fisheries

LANDSAT thematic mapper (TM) data are being used to refine and validate a stochastic spatial computer model to be applied to coastal resource management problems in Louisiana. Two major aspects of the research are: (1) the measurement of area of land (or emergent vegetation) and water and the length of the interface between land and water in TM imagery of selected coastal wetlands (sample marshes); and (2) the comparison of spatial patterns of land and water in the sample marshes of the imagery to that in marshes simulated by a computer model. In addition to activities in these two areas, the potential use of a published autocorrelation statistic is analyzed

Relationship Between Mechanical And Physiological Energy Costs And Efficiency Of Treadmill Walking In Active And Inactive Females

Energy costs of walking are traditionally examined from two perspectives biomechanical and physiological. Biomechanists use mechanical energy costs to calculate mechanical work (MW) performed by the body. Physiologists use energy expenditure to calculate metabolic cost (MC) of the activity. These two values are then used to calculate efficiency values for walking. However, few researchers have examined the rela tionship between these two forms of energy cost (MW and MC) and the calculated efficiency value (EFF). The purpose of this study was to examine the relationship between MW and MC, MW and EFF, and MC and EFF during treadmill walking in active (ACT) and inactive (INCT) females. It was hypothesized that a high correlation would exist between MW and MC because the amount of work done by the segments would be dependent on the amount of energy expended by the muscles for muscle contraction to move the segments. Two groups (ACT and INCT) of 12 females participated in a 10-min submax walking test. Submax V02 and 3D film records (100 fps) were obtained during the final minute of the test. MW, MC, and EFF were calculated using the method recommended by Cavanagh and Williams (1983). Correlations for each group were calculated between MW and MC (ACT: r= .340; INCT: r= .429), MC and EFF (ACT: r= -.271; INCT: r = -.149), and MW and EFF (ACT: r= .854; INCT: r= .817). Significant correlations were found between MW and EFF for both groups (p f. .01). No relationship was found between MW and MC for either group. Biomechanists have attempted to adjust MW by developing methods for approximating the amount of mechanical energy conserved by energy transfer within and between segments, by the storage of elastic energy, and by the performance of negative work as opposed to positive work. This leads to a more accurate representation of mechanical energy cost related

Prospects for Direct CP Violaton in Exclusive and Inclusive Charmless B decays

Within the Standard Model, CP rate asymmetries for $B\to K^-\pi^{+,0}$ could reach 10%. With strong final state phases, they could go up to 20--30%, even for $\bar K^0\pi^-$ mode which would have opposite sign. We can account for $K^-\pi^{+}$, $\bar K^0\pi^-$ and $\phi K$ rate data with new physics enhanced color dipole coupling and destructive interference. Asymmetries could reach 40--60% for $K\pi$ and $\phi K$ modes and are all of the same sign. We are unable to account for $K^-\pi^0$ rate. Our inclusive study supports our exclusive results.Comment: Minor changes, correct a small bug in Fig. 1(b). Version to appear in Phys. Rev. Let

Solving the SUSY CP problem with flavor breaking F-terms

Supersymmetric flavor models for the radiative generation of fermion masses offer an alternative way to solve the SUSY-CP problem. We assume that the supersymmetric theory is flavor and CP conserving. CP violating phases are associated to the vacuum expectation values of flavor violating susy-breaking fields. As a consequence, phases appear at tree level only in the soft supersymmetry breaking matrices. Using a U(2) flavor model as an example we show that it is possible to generate radiatively the first and second generation of quark masses and mixings as well as the CKM CP phase. The one-loop supersymmetric contributions to EDMs are automatically zero since all the relevant parameters in the lagrangian are flavor conserving and as a consequence real. The size of the flavor and CP mixing in the susy breaking sector is mostly determined by the fermion mass ratios and CKM elements. We calculate the contributions to epsilon, epsilon^{prime} and to the CP asymmetries in the B decays to psi Ks, phi Ks, eta^{\prime} Ks and Xs gamma. We analyze a case study with maximal predictivity in the fermion sector. For this worst case scenario the measurements of Delta mK, Delta mB and epsilon constrain the model requiring extremely heavy squark spectra.Comment: 21 pages, RevTex

Data-Based Decisions Guidelines for Teachers of Students with Severe Intellectual and Developmental Disabilities

Effective practices in student data collection and implementation of data-based instructional decisions are needed for all educators, but are especially important when students have severe intellectual and develop- mental disabilities. Although research in the area of data-based instructional decisions for students with severe disabilities shows benefits for using data, there is limited research to demonstrate teachers in applied settings can acquire the decision-making skills required. The purpose of this research was to demonstrate how teachers from five states acquired a set of data-based decisions implementation guidelines through online professional development. Recommendations for practice and future research are included

Species Composition and Seasonality of the Smallest Size Class of Shrimp in the Tortugas Fishery of Florida

Shrimps from the smallest commercial size class (68 or more heads-off shrimp per 454 g) were analyzed from samples collected at the Tortugas fishing grounds from March 2002 through March 2004. Pink shrimp Farfantepenaeus duorarum and yellow roughneck shrimp Rimapenaeus similis occurred together in 90% of the samples, comprising 65.4% and 27.2% of individuals, respectively. Estimates of the proportion and seasonality of both species in the shrimp samples were combined with an analysis of the smallest size class in the Tortugas landings data. Our analysis suggested that yellow roughneck shrimp make up 23.6% by number of the smallest shrimp catch and constitute 6.6% by weight of total shrimp landings, very similar results to those from 1959. Results also indicated that there was a significant difference in the seasonality of each species during the collection period. A follow-up study of this unreported yellow roughneck shrimp is recommended to ensure sound data and good management for this important fishery

An imaging time-of-propagation system for charged particle identification at a super B factory

Super B factories that will further probe the flavor sector of the Standard Model and physics beyond will demand excellent charged particle identification (PID), particularly K/pi separation, for momenta up to 4 GeV/c, as well as the ability to operate under beam backgrounds significantly higher than current B factory experiments. We describe an Imaging Time-of-Propagation (iTOP) detector which shows significant potential to meet these requirements. Photons emitted from charged particle interactions in a Cerenkov radiator bar are internally reflected to the end of the bar, where they are collected on a compact image plane using photodetectors with fine spatial segmentation in two dimensions. Precision measurements of photon arrival time are used to enhance the two dimensional imaging, allowing the system to provide excellent PID capabilities within a reduced detector envelope. Results of the ongoing optimization of the geometric and physical properties of such a detector are presented, as well as simulated PID performance. Validation of simulations is being performed using a prototype in a cosmic ray test stand at the University of Hawaii.Comment: 3 pages, 5 figures, submitted to TIPP09 proceeding
