The Potential of the Port of New York in the Export/Domestic Coal Trade

This paper researches the potential of the Port of New York in the Export/Domestic coal trade markets.The Port is faced with short-term and long-term proposals in order to enter these markets. On a short-term basis, the Port will be able to offer an advantage to export markets because of the backlog at the traditional coal ports of Hampton Roads, Baltimore, and Philadelphia. A modest export trade can develop this way. In the domestic trade, substantial inroads can be made due to the conversion of power plants in New England to coal-fired. In the long-term, the Port is faced with the primary issues of dredging, establishing a competitive freight rate, and environmental constraints. These particular issues must be resolved in order for the Port to effectively compete in the export markets. In the domestic markets, the Port must be able to provide a portion of the terminal for the coastal trade exclusively

Asymmetrical distribution of non-conserved regulatory sequences at PHOX2B is reflected at the ENCODE loci and illuminates a possible genome-wide trend

<p>Abstract</p> <p>Background</p> <p>Transcriptional regulatory elements are central to development and interspecific phenotypic variation. Current regulatory element prediction tools rely heavily upon conservation for prediction of putative elements. Recent <it>in vitro </it>observations from the ENCODE project combined with <it>in vivo </it>analyses at the zebrafish <it>phox2b </it>locus suggests that a significant fraction of regulatory elements may fall below commonly applied metrics of conservation. We propose to explore these observations <it>in vivo </it>at the human <it>PHOX2B </it>locus, and also evaluate the potential evidence for genome-wide applicability of these observations through a novel analysis of extant data.</p> <p>Results</p> <p>Transposon-based transgenic analysis utilizing a tiling path proximal to human <it>PHOX2B </it>in zebrafish recapitulates the observations at the zebrafish <it>phox2b </it>locus of both conserved and non-conserved regulatory elements. Analysis of human sequences conserved with previously identified zebrafish <it>phox2b </it>regulatory elements demonstrates that the orthologous sequences exhibit overlapping regulatory control. Additionally, analysis of non-conserved sequences scattered over 135 kb 5' to <it>PHOX2B</it>, provides evidence of non-conserved regulatory elements positively biased with close proximity to the gene. Furthermore, we provide a novel analysis of data from the ENCODE project, finding a non-uniform distribution of regulatory elements consistent with our <it>in vivo </it>observations at <it>PHOX2B</it>. These observations remain largely unchanged when one accounts for the sequence repeat content of the assayed intervals, when the intervals are sub-classified by biological role (developmental versus non-developmental), or by gene density (gene desert versus non-gene desert).</p> <p>Conclusion</p> <p>While regulatory elements frequently display evidence of evolutionary conservation, a fraction appears to be undetected by current metrics of conservation. <it>In vivo </it>observations at the <it>PHOX2B </it>locus, supported by our analyses of <it>in vitro </it>data from the ENCODE project, suggest that the risk of excluding non-conserved sequences in a search for regulatory elements may decrease as distance from the gene increases. Our data combined with the ENCODE data suggests that this may represent a genome wide trend.</p

As such, a detailed understanding of the hygroscopic growth of an aerosol during inhalation is necessary to accurately model the deposited dose. In the first part of this study, it is demonstrated that the aerosol produced by a nebulizer, depending on the airflows rates, may experience a (predictable) wide range of relative humidity prior to inhalation and undergo dramatic changes in both size and solute concentration. A series of sensitive single aerosol analysis techniques are then used to make measurements of the relative humidity dependent thermodynamic equilibrium properties of aerosol generated from four common nebulizer formulations. Measurements are also reported of the kinetics of mass transport during the evaporation or condensation of water from the aerosol. Combined, these measurements allow accurate prediction of the temporal response of the aerosol size prior to and during inhalation. Specifically, we compare aerosol composed of pure saline (150 mM sodium chloride solution in ultrapure water) with two commercially available nebulizer products containing relatively low compound doses: Breath, consisting of a simple salbutamol sulfate solution (5 mg/2.5 mL; 1.7 mM) in saline, and Flixotide Nebules, consisting of a more complex stabilized fluticasone propionate suspension (0.25 mg/mL; 0.5 mM in saline. A mimic of the commercial product Tobi (60 mg/mL tobramycin and 2.25 mg/mL NaC1, pH 5.5-6.5) is also studied, which was prepared in house. In all cases, the presence of the pharmaceutical was shown to have a profound effect on the magnitude, and in some cases the rate, of the mass flux of water to and from the aerosol as compared to saline. These findings provide physical chemical evidence supporting observations from human inhalation studies, and suggest that using the growth dynamics of a pure saline aerosol in a lung inhalation model to represent nebulizer formulations may not be representative of the actual behavior of the aerosolized drug solutions.
