Shellfish Tissue Monitoring in Piscataqua Region Estuaries 2010 and 2011
Conducted by a committee of Canadian and US government and university scientists, Gulfwatch examines the effects of decades of development and industrialization on the water quality of the Gulf as it relates to human health primarily through assessing contaminant exposure of marine organisms. Gulfwatch scientists collect blue mussels at over 60 US and Canadian sites Gulfwide, and analyze the organismsâ tissue for potentially harmful levels and concentrations of toxins including heavy metals, chlorinated pesticides, polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs)
Shellfish Tissue Monitoring in Piscataqua Region Estuaries 2012
Originally conducted by a committee of Canadian and US governments and university scientists, Gulfwatch examined the effects of decades of development and industrialization on the water quality of the Gulf of Maine as it relates to human health primarily through assessing contaminant exposure of marine organisms from 1993 to 2010. The NH Gulfwatch Program continues these efforts by collecting blue mussels at two sites in the Great Bay Estuary and one in the Hampron-Seabrook Estuary, and analyzes the organismsâ tissue for potentially harmful levels and concentrations of toxins including heavy metals, chlorinated pesticides, polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs). During the 2012 sampling season, mussels were collected at three sampling locations in New Hampshire and Maine (MECC, NHHS and NHDP)
Shellfish Tissue Monitoring in Piscataqua Region Estuaries 2013
Originally conducted by the Gulf of Maine Council on the Marine Environment from 1993 to 2011, the Gulfwatch Program examined trends in the water quality of the Gulf of Maine by monitoring toxic contaminant concentrations in the tissues of shellfish. Starting in 2012 the Piscataqua Region Estuaries Partnership (PREP) continued this program in the Piscataqua Region. Each year, PREP collects blue mussels at three sites: Dover Point, NH (NHDP), Clark Cove on Seavey Island, ME (MECC), and Hampton-Seabrook Harbor (NHHS). The mussel tissue is analyzed to determine the concentrations of toxic contaminantss including heavy metals, chlorinated pesticides, polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs)
Shellfish Tissue Monitoring in Piscataqua Region Estuaries 2010: Final Report
Gulfwatch examines the effects of decades of development and industrialization on the water quality of the Gulf as it relates to human health primarily through assessing contaminant exposure of marine organisms. Gulfwatch scientists collect blue mussels at over 60 US and Canadian sites Gulfwide, and analyze the organismsâ tissue for potentially harmful levels and concentrations of toxins including heavy metals, chlorinated pesticides, polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs). New Hampshire increased the number of Gulfwatch sampling locations from two sites per year in 1997 to an average of five sites per year from 1998-2010. The increased spatial coverage provides comprehensive information for contaminant concentrations throughout the New Hampshire estuarine waters. All samples collected for the Gulfwatch monitoring program, from the Canadian provinces as well as the New England states involved, have been sent to the same laboratories for analysis. All of the samples have been analyzed at the same time in the same laboratories in an effort to reduce error and variability. This practice has ensured the consistency that was necessary to allow a region-wide assessment of the health of the Gulf. During the 2010 sampling season, mussels were collected at six sampling locations in New Hampshire and Maine (MECC, NHHS, NHDP, NHRH, NHPI and NHLH). Project Goals and Objectives The goal of this project was to provide data for two PREP indicators of estuarine condition: TOX1 and TOX3. These two indicators report on âShellfish tissue concentrations relative to FDA standardsâ and âTrends in shellfish tissue contaminant concentrationsâ, respectively. Both of these indicators depend on data from the Gulfwatch Program. In particular, TOX3 requires annual data at benchmark sites to assess trends. In 2010, PREP supported the collection and analysis of tissue samples from benchmark mussel sites in Hampton-Seabrook Harbor and Dover Point

Hydrodynamics of the stream-disk impact in interacting binaries
We use hydrodynamic simulations to provide quantitative estimates of the
effects of the impact of the accretion stream on disks in interacting binaries.
For low accretion rates, efficient radiative cooling of the hotspot region can
occur, and the primary consequence of the stream impact is stream overflow
toward smaller disk radii. The stream is well described by a ballistic
trajectory, but larger masses of gas are swept up and overflow at smaller, but
still highly supersonic, velocities. If cooling is inefficient, overflow still
occurs, but there is no coherent stream inward of the disk rim. Qualitatively,
the resulting structure appears as a bulge extending downstream along the disk
rim. We calculate the mass fraction and velocity of the overflowing component
as a function of the important system parameters, and discuss the implications
of the results for X-ray observations and doppler tomography of cataclysmic
variables, low-mass X-ray binaries and supersoft X-ray sources.Comment: 16 pages, including 8 figures. 1 color figure as a jpeg. ApJ, in

General practitioner provision of preventive child health care: analysis of routine consultation data
<b>Background</b> GPs contribute to preventive child health care in various ways, including provision of child health
surveillance (CHS) reviews, opportunistic preventive care, and more intensive support to vulnerable children. The
number of CHS reviews offered in Scotland was reduced from 2005. This study aimed to quantify GPsâ provision of
different types of preventive care to pre-school children before and after the changes to the CHS system.<p></p>
<b>Methods</b> GP consultation rates with children aged 0â4 years were examined for the 2½ years before and after the
changes to the CHS system using routinely available data from 30 practices in Scotland. Consultations for CHS
reviews; other aspects of preventive care; and all reasons were considered.<p></p>
<b>Results:</b> Prior to the changes to the CHS system, GPs often contributed to CHS reviews at 6â8 weeks and 8â9 and
39â42 months. Following the changes, GP provision of the 6â8 week review continued but other reviews
essentially ceased. Few additional consultations with pre-school children are recorded as involving other aspects of
preventive care, and the changes to CHS have had no impact on this. In the 2½ years before and after the changes,
consultations recorded as involving any form of preventive care accounted for 11% and 7.5% respectively of all
consultations with children aged 0â4 years, with the decline due to reductions in CHS reviews.<p></p>
<b>Conclusions:</b> Effective preventive care through the early years can help children secure good health and
developmental outcomes. GPs are well placed to contribute to the provision of such care. Consultations focused on
preventive care form a small minority of GPsâ contacts with pre-school children, however, particularly since the
reduction in the number of CHS reviews
