Wychwood Wild Garden Aquatic Survey Final report to support the restoration of the ponds

Wychwood Wild Garden (WWG) is an area of woodland and historic garden which once formed part of Shipton Court, but is now managed and owned by the local community. Within the Wild Garden are two ponds, both artificial in creation, but dating back to the 19th century. In addition to the ponds, the water flows north through “The Lifts”, a series of three canals, each with a low cascade to the one below; the final one having a sluice at the northern boundary of the gardens where the water forms a headwater tributary of the River Evenlode

Profiling the Frequent Clothing Shopper

Frequent shoppers are an important segment of consumers for the clothing industry because they account for a disproportionate amount of sales and profits and play an important role in the fashion diffusion process. The purpose of this study was to test hypothesized characteristics that distinguish frequent shoppers clothing from other buyers. We focused on characteristics that have been studied by previous researchers and characteristics that have received less study, but are no less interesting and potentially important to clothing marketing and management

Llyn Anafon: Ecological assessment of the aquatic flora to support HRA, 2017

Llyn Anafon lies within the Eryri SAC, North Gwynedd, Wales (500 m amsl). Originally a natural lake, the level was raised by approximately 1.5 m in 1929 to provide potable water. Although now out of active commission for water supply, the site owners Dwr Cymru / Welsh Water (DCWW) maintain the responsibility for the dam and the site remains within the jurisdiction of the Reservoirs Act 1975. Deterioration of the retaining dam resulted in the most recent Section 10 report to conclude that the risk of failure exceeded acceptable levels and that a long-term solution is required in the interests of public safety. This report triggered DCWW to consider a series of engineering options ranging from full repair to complete removal of the dam, with decommissioning being the favoured plan for the long-term sustainability and safety of the site

Gaudet Luce Golf & Leisure Complex, Worcestershire: Report on aquatic habitats 2017

Gaudet Luce Golf & Leisure Complex is located in the county of Worcestershire (Figure 1), southeast of Droitwich Spa town. Founded in 1995, the golf course has undergone an extensive transformation which has included a new Par Three course, reconfiguration of the 18 hole Phoenix Course and the planting of over 50,000 trees across the golf complex, which were supplied to Gaudet Luce via a Forestry Commission grant. Drainage systems have also been improved over time, alongside the installation of new bunkers and tee renovation (Midlands Business News, 2013; Fernihough, 2017)

Is the number of Photons a Classical Invariant?

We describe an apparent puzzle in classical electrodynamics and its resolution. It is concerned with the Lorentz invariance of the classical analog of the number of photons.Comment: Revised version, 3 figure

Magnetic Field Structure around Low-Mass Class 0 Protostars: B335, L1527 and IC348-SMM2

We report new 350 micron polarization observations of the thermal dust emission from the cores surrounding the low-mass, Class 0 YSOs L1527, IC348-SMM2 and B335. We have inferred magnetic field directions from these observations, and have used them together with results in the literature to determine whether magnetically regulated core-collapse and star-formation models are consistent with the observations. These models predict a pseudo-disk with its symmetry axis aligned with the core magnetic field. The models also predict a magnetic field pinch structure on a scale less than or comparable to the infall radii for these sources. In addition, if the core magnetic field aligns (or nearly aligns) the core rotation axis with the magnetic field before core collapse, then the models predict the alignment (or near alignment) of the overall pinch field structure with the bipolar outflows in these sources. We show that if one includes the distorting effects of bipolar outflows on magnetic fields, then in general the observational results for L1527 and IC348-SMM2 are consistent with these magnetically regulated models. We can say the same for B335 only if we assume the distorting effects of the bipolar outflow on the magnetic fields within the B335 core are much greater than for L1527 and IC348-SMM2. We show that the energy densities of the outflows in all three sources are large enough to distort the magnetic fields predicted by magnetically regulated models.Comment: Accepted for publication in The Astrophysical Journa

Ovalbumin sensitization and challenge increases the number of lung cells possessing a mesenchymal stromal cell phenotype

Abstract Background Recent studies have indicated the presence of multipotent mesenchymal stromal cells (MSCs) in human lung diseases. Excess airway smooth muscle, myofibroblasts and activated fibroblasts have each been noted in asthma, suggesting that mesenchymal progenitor cells play a role in asthma pathogenesis. We therefore sought to determine whether MSCs are present in the lungs of ovalbumin (OVA)-sensitized and challenged mice, a model of allergic airways disease. Methods Balb/c mice were sensitized and challenged with PBS or OVA over a 25 day period. Flow cytometry as well as colony forming and differentiation potential were used to analyze the emergence of MSCs along with gene expression studies using immunochemical analyses, quantitative polymerase chain reaction (qPCR), and gene expression beadchips. Results A CD45-negative subset of cells expressed Stro-1, Sca-1, CD73 and CD105. Selection for these markers and negative selection against CD45 yielded a population of cells capable of adipogenic, osteogenic and chondrogenic differentiation. Lungs from OVA-treated mice demonstrated a greater average colony forming unit-fibroblast (CFU-F) than control mice. Sorted cells differed from unsorted lung adherent cells, exhibiting a pattern of gene expression nearly identical to bone marrow-derived sorted cells. Finally, cells isolated from the bronchoalveolar lavage of a human asthma patient showed identical patterns of cell surface markers and differentiation potential. Conclusions In summary, allergen sensitization and challenge is accompanied by an increase of MSCs resident in the lungs that may regulate inflammatory and fibrotic responses.http://deepblue.lib.umich.edu/bitstream/2027.42/78265/1/1465-9921-11-127.xmlhttp://deepblue.lib.umich.edu/bitstream/2027.42/78265/2/1465-9921-11-127.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/78265/3/1465-9921-11-127-S1.DOCPeer Reviewe

Detection of a dense clump in a filament interacting with W51e2

In the framework of the Herschel/PRISMAS Guaranteed Time Key Program, the line of sight to the distant ultracompact HII region W51e2 has been observed using several selected molecular species. Most of the detected absorption features are not associated with the background high-mass star-forming region and probe the diffuse matter along the line of sight. We present here the detection of an additional narrow absorption feature at ~70 km/s in the observed spectra of HDO, NH3 and C3. The 70 km/s feature is not uniquely identifiable with the dynamic components (the main cloud and the large-scale foreground filament) so-far identified toward this region. The narrow absorption feature is similar to the one found toward low-mass protostars, which is characteristic of the presence of a cold external envelope. The far-infrared spectroscopic data were combined with existing ground-based observations of 12CO, 13CO, CCH, CN, and C3H2 to characterize the 70 km/s component. Using a non-LTE analysis of multiple transitions of NH3 and CN, we estimated the density (n(H2) (1-5)x10^5 cm^-3) and temperature (10-30 K) for this narrow feature. We used a gas-grain warm-up based chemical model with physical parameters derived from the NH3 data to explain the observed abundances of the different chemical species. We propose that the 70 km/s narrow feature arises in a dense and cold clump that probably is undergoing collapse to form a low-mass protostar, formed on the trailing side of the high-velocity filament, which is thought to be interacting with the W51 main cloud. While the fortuitous coincidence of the dense clump along the line of sight with the continuum-bright W51e2 compact HII region has contributed to its non-detection in the continuum images, this same attribute makes it an appropriate source for absorption studies and in particular for ice studies of star-forming regions.Comment: Accepted for publication in A&
