Based on the connotation analysis of the value of water resources, the theory and practice study for price of water resources were developed. The supply price of water resources should be composed of water resources fee, cost of supply and environment compensation fee for water. Demand price of water resources should be determined by economic value of water resources. Market price of water resources should be determined by provide price and demand price, and it could be evaluated by shadow price in non-marketization system. According to the equilibrium relation of water price, quantitative evaluation method for water resources fee was put forward. Based on the simplified CGE model and related methods, some key factors were quantitatively evaluated, such as shadow price, economic value, water resources fee, supply cost and environment compensation fee for water. The output of this study will provide theory support for pricing mechanism of water resources and practice support for pricing standard. The achievements are significant for practicing most strict water resources management, setting up price mechanism of water resources, allocating water resources by price lever. Source

Long-term trend and abrupt changes of major climate variables in the Taihu Basin were investigated based on the mean, maximum and minimum air temperature, diurnal temperature range (DTR), precipitation, relative humidity and sunshine duration at six meteorological stations from 1954 to 2006. Results showed that the long-term trend for annual precipitation was not statistically significant during the past 53 years, but a wetter tendency was detected and the increasing centre for annual precipitation was located in the southeast of the study area. Mean air temperature has increased by 1.43°C, similar trends were also identified for maximum and minimum air temperature, which have increased by 1.06 and 1.54°C, respectively, while DTR exhibited a slight decreasing trend with a rate of about -0.09°C/(10 year). The annual mean relative humidity and sunshine duration exhibited a decreasing trend, with Kendall slope values of -0.99%/10 year and -7.797 h/10 year, respectively. Examination of long-range dependence showed that all climate variables exhibited strong persistence at annual scale except minimum air temperature. Detection of abrupt changes using nonparametric Mann-Kendall and Pettitt methods showed different results. Abrupt changes occurred in the 1980s and 2000s for annual precipitation using the nonparametric Mann-Kendall method, while no abrupt changes were detected using the Pettitt method. Abrupt changes of temperature and relative humidity took place in the early 1990s using the nonparametric Mann-Kendall method, which occurred in the late and mid 1980s using the Pettitt method, while abrupt changes of sunshine duration and DTR detected by two methods occurred in the similar period. The result will be helpful for local flood control and drought relief in urban planning and construction under future global climate change. © 2011 Springer-Verlag. Source

The use of groundwater for cooling and heating purposes is of interest from both the economical and the ecological perspective. The groundwater heat pump (GWHP) system utilizes groundwater as alternative renewable and clean energy source for space heating and/or cooling, withdraws water from a production well, passes it through a heat exchanger and discharges the water into an injection well. By utilizing the relatively stable temperature of groundwater, GWHP system can achieve a higher coefficient of performance. Due to the utilization of groundwater stored in the aquifer, the assessment of the hydraulic capacity of the aquifer based on numerical groundwater models is always needed for the optimum design and the efficient performance of GWHP. In this paper, numerical methods of underground heat-water transfer, energy balance method and thermal storage method were presented to calculate the capacity of unit area of shallow groundwater aquifer. The model results indicate that the numerical method, which is based on performance efficiency of GWHP, represents the behaviour of groundwater pumping/recharging processes, and serves better than energy balance method and thermal storage method, in addition it has been proven itself that this method has the advantages of energy saving and environmental protection. The calculated capacity is positively related to aquifer thickness. It is found that it is easy for ground water recharge in alluvial and pluvial fan located at the piedmont, while the calculated capacity is relatively smaller compared with that of south-east plain where it is not easy for groundwater recharge. © 2011 Elsevier B.V.

Law School Poised to Conquer Revson Plaza
Written by Bwog Staff

Well not Revson Plaza, really. What do you call that spot on the EC/SIPA/Law School plaza that's right behind the Law School and looks down into the Wien courtyard? As of sometime in 2011, you'll call it the fancy new Law School extension, and if you have Law Library privileges, you'll call it "the reading room that looks like Star Trek mission control."
The expansion plans are the doing of Ennead Architects, a firm previously known as the Polshek Partnership. They are responsible under that name for well-known projects such as The Standard Hotel (the one over the High Line) and a number of expansions and redesigns of already iconic buildings like Carnegie Hall. Neither Ennead nor the Law Library could be reached for comment, but full plans for the expansion currently appear on Ennead's website.
The plans calls for an addition that blends into the modern facade of the existing building, emphasizing vertical and minimizes horizontal lines. The addition departs, however, from its host structure in medium – the panels in between the vertical fins you see below are made of glass, and so are those fins themselves. Click through the plan drawings to get a better sense of the new space (be warned, you'll be prompted to get the latest Adobe Flash if you don't have it). Here's another view:
Seats at the long tables probably give an excellent view of sky and surroundings, from a flying boardroom sort of perspective. How cool it would be to drive the law school spaceship – from your newly designed, state-of-the art, full-visibility cockpit – straight into Wien and then into the heavens!

The purpose was to monitor implanted seeds and to determine factors contributing to seed migration after permanent prostate brachytherapy.
Sixty-two consecutive patients with Stage 1 prostate cancer who underwent brachytherapy with (125)I seeds between February 2008 and May 2009 were studied prospectively. On post-operative days 1, 7 and 30, scintigraphy was added to conventional radiography to monitor the migration of the implanted seeds. The prostate volume was measured during the pre-planning stage using ultrasound and during the post-planning stage using computed tomography on post-operative days 0 and 30. Magnetic resonance imaging was performed on day 30.
Of the 4843 seeds implanted in the prostates of 62 patients, 108 seeds (2.2%) in 43 patients (69.4%) exhibited seed migration. Thirty-five seeds could not be identified using any of the imaging modalities and were likely passed during urination (0.7% of the total number of seeds). The maximum number of migrated seeds in one patient was 10 of the 85 implanted seeds. The fraction of patients with seed migration or loss increased from 27.4% on day 1 to 69.4% on day 30. The number of seeds that had migrated from the prostate increased from 48 (0.1% of the total number of seeds) on 1 day to 78 (1.0%) on day 7 and 108 (2.2%) on day 30. Of the seeds lost from the prostate, 38.9% embolized to the lungs. The seed loss during the first post-operative month was closely correlated with the swelling of the prostate gland between the pre-planning measurement and the post-planning measurement performed on day 0 (P < 0.0001).
Prostate swelling between the pre-planning and post-planning (day 0) measurements was significantly associated with seed migration, and adequate attention should be given to this issue.

Prostatic Secretory Proteins
Proteins secreted by the prostate gland. The major secretory proteins from the human prostate gland include PROSTATE-SPECIFIC ANTIGEN, prostate-specific acid phosphatase, prostate-specific membrane antigen, and prostate-specific protein-94.
Prostate-specific Antigen
A glycoprotein that is a kallikrein-like serine proteinase and an esterase, produced by epithelial cells of both normal and malignant prostate tissue. It is an important marker for the diagnosis of prostate cancer.
A lactogenic hormone secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). It is a polypeptide of approximately 23 kD. Besides its major action on lactation, in some species prolactin exerts effects on reproduction, maternal behavior, fat metabolism, immunomodulation and osmoregulation. Prolactin receptors are present in the mammary gland, hypothalamus, liver, ovary, testis, and prostate.
Cell Migration Inhibition
Phenomenon of cell-mediated immunity measured by in vitro inhibition of the migration or phagocytosis of antigen-stimulated LEUKOCYTES or MACROPHAGES. Specific CELL MIGRATION ASSAYS have been developed to estimate levels of migration inhibitory factors, immune reactivity against tumor-associated antigens, and immunosuppressive effects of infectious microorganisms.
Carcinoma, Ductal
Malignant neoplasms involving the ductal systems of any of a number of organs, such as the MAMMARY GLANDS, the PANCREAS, the PROSTATE, or the LACRIMAL GLAND.
