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
Crystallization of the gene 45 protein from the DNA replication fork of bacteriophage T4
The gene 45 protein from bacteriophage T4 has been purified and is crystallized. This protein is part of the T4 DNA replication complex. The crystallized protein is active in complementation assays. X-ray diffraction analysis is in progress; data are measured for the native and several heavy atom derivatives. The crystals diffract to about 3.5-Å resolution
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
