Using the Storm Water Management Model to Predict Urban Headwater Stream Hydrological Response to Climate and Land Cover Change : Volume 17, Issue 12 (03/12/2013)

By: K. J. Franz; R. K. Kolka; J. R. Thompson; J. Y. Wu; T. W. Stewart

Description: Department of Natural Resource Ecology and Management, Iowa State University, Ames, IA, USA. Streams are natural features in urban landscapes that can provide ecosystem services for urban residents. However, urban streams are under increasing pressure caused by multiple anthropogenic impacts, including increases in human population and associated impervious surface area, and accelerated climate change. The ability to anticipate these changes and better understand their effects on streams is important for developing and implementing strategies to mitigate potentially negative effects. In this study, stream flow was monitored during April–November (2011 and 2012), and the data were used to apply the Storm Water Management Model (SWMM) for five urban watersheds in central Iowa, USA, representing a gradient of percent impervious surface (IS, ranging from 5.3 to 37.1%). A set of three scenarios was designed to quantify hydrological responses to independent and combined effects of climate change (18% increase in precipitation), and land cover change (absolute increases between 5.2 and 17.1%, based on separate pr...

Plos One : Vitamin E Δ-tocotrienol Induces P27Kip1-dependent Cell- Cycle Arrest in Pancreatic Cancer Cells Via an E2F-1- Dependent Mechanism, Volume 7

By: Wael El-rifai

Description : Vitamin E d-tocotrienol has been shown to have antitumor activity, but the precise molecular mechanism by which it inhibits the proliferation of cancer cells remains unclear. Here, we demonstrated that d-tocotrienol exerted significant cell growth inhibition pancreatic ductal cancer (PDCA) cells without affecting normal human pancreatic ductal epithelial cell growth. We also showed that d-tocotrienol-induced growth inhibition occurred concomitantly with G1 cell-cycle arrest and increased p27Kip1 nuclear accumulation. This finding is significant considering that loss of nuclear p27Kip1 expression is a well-established adverse prognostic factor in PDCA. Furthermore, d-tocotrienol inactivated RAF-MEK-ERK signaling, a pathway known to suppress p27Kip1 expression. To determine whether p27Kip1 induction is required for d-tocotrienol inhibition of PDCA cell proliferation, we stably silenced the CDKN1B gene, encoding p27Kip1, in MIAPaCa-2 PDCA cells and demonstrated that p27Kip1 silencing suppressed cell-cycle arrest induced by d-tocotrienol. Furthermore, d-tocotrienol induced p27Kip1 mRNA expression but not its protein degrad...

Plos Pathogens : Escape. in Each of the Subjects, Nabs Targeted Different Regions of the Hiv-1 Envelope Env in a Strain-specific,, Volume No. 6

By: Andrew P. Rice

Description : Apoptosis in HIV-1-infected CD4+ primary T cells is triggered by the alteration of the PI3K and p53 pathways, which converge on the FOXO3a transcriptional activator. Tat alone can cause activation of FOXO3a and of its proapoptotic target genes. To understand how Tat affects this pathway, we carried out ChIP-Chip experiments with Tat. Tat associates with the promoters of PTEN and two PP2A subunit genes, but not with the FOXO3a promoter. PTEN and PP2A encode phosphatases, whose levels and activity are increased when Tat is expressed. They counteract phosphorylation of Akt1 and FOXO3a, and so activate transcriptional activity of FOXO3a. FOXO3a promotes increased transcription of Egr-1, which can further stimulate the transcription of PTEN, thereby reinforcing the pathway that leads to FOXO3a transcriptional activation. RNAi experiments support the role of PTEN and PP2A in the initiation of the Tat-mediated cascade, which is critical to apoptosis. The increased accumulation of PTEN and PP2A subunit mRNAs during Tat expression is more likely to be the result of increased transcription initiation and not relief of promoter-p...

Selected Lead Articles from the Dawn

By: Dora Falconer

Excerpt: ?WOMAN is not uncompleted man, but diverse,? says Tennyson, and being diverse why should she not have her journal in which her divergent hopes, aims and opinions may have representation. Every eccentricity of belief, and every variety of bias in mankind allies itself with a printing?machine, and gets its singularities bruited about in type, but where is the printing ink champion of mankind?s better half? There has hitherto been no trumpet through which the concentrated voices of womankind could publish their grievances and their opinions. Men legislate on divorce, on hours of labor, and many another question intimately affecting women, but neither ask nor know the wishes of those whose lives and happiness are most concerned. Many a tale might be told by women, and many a useful hint given, even to the omniscient male, which would materially strengthen and guide the hands of law?makers and benefactors aspiring to be just and generous to weak and unrepresented womankind. Here then is DAWN, the Australian Woman?s journal and mouthpiece?a phonograph to wind out audibly the whispers, pleadings and demands of the sisterhood. Here...

Physical Controls on the Scale-dependence of Ensemble Streamflow Forecast Dispersion : Volume 10, Issue 7 (23/07/2010)

By: E. R. Vivoni; G. Mascaro; R. Deidda

Description: Dipartimento di Ingegneria del Territorio, Università di Cagliari, Cagliari, Italy. The accuracy of ensemble streamflow forecasts (ESFs) is impacted by the propagation of uncertainty associated with quantitative precipitation forecasts (QPFs) through the physical processes occurring in the basin. In this study, we consider consistent ESFs (i.e., observations and ensemble members are equally likely) and we study the effect of basin area (A) and antecedent rainfall (AR) on the ESF dispersion, a metric of flood forecast skill. Results from a set of numerical experiments indicate that: (i) for small basins (≲180 km2), ESF dispersion is mainly dominated by the runoff generation process and does not depend on the basin size A; (ii) for larger areas, ESF dispersion decreases with A according to a log-linear relation due to the decreasing variability of ensemble QPFs and, possibly, to the channel routing process. In addition, we found that, regardless the basin size, the ESF dispersion decreases as AR increases, and that the influence of AR is larger for basins with fast respo...

North Atlantic Oscillation and Tropospheric Ozone Variability in Europe: Model Analysis and Measurements Intercomparison : Volume 12, Issue 1 (30/01/2012)

By: E. Vignati; F. J. Dentener; L. Pozzoli; F. S. R. Pausata

Description: European Commission, Joint Research Center, Institute for Environment and Sustainability, Ispra (VA), Italy. Ozone pollution represents a serious health and environmental problem. While ozone pollution is mostly produced by photochemistry in summer, elevated ozone concentrations can also be influenced by long range transport driven by the atmospheric circulation and stratospheric ozone intrusions. We analyze the role of large scale atmospheric circulation variability in the North Atlantic basin in determining surface ozone concentrations. Here, we show, using ground station measurements and a coupled atmosphere-chemistry model simulation for the period 1980–2005, that the North Atlantic Oscillation (NAO) does affect surface ozone concentrations – on average, over 10 ppbv on the monthly mean in southwestern, central and northern Europe – during all seasons except fall. The commonly used NAO index is able to capture the link existing between atmospheric dynamics and surface ozone concentrations in winter and spring but it fails in summer. We find that the first Principal Component, computed from the time vari...

Comment on 100-year Mass Changes in the Swiss Alps Linked to the Atlantic Multidecadal Oscillation by Matthias Huss Et Al. (2010) : Volume 4, Issue 4 (17/11/2010)

By: R. S. W. Van De Wal; J. Oerlemans; P. W. Leclercq

Description: IMAU, Universiteit Utrecht, Utrecht, The Netherlands. The paper by Huss et al. (2010) presents a comprehensive set of 100-year specific mass balance series for 30 Swiss glaciers. In the second part of the paper, the authors relate the fluctuations in alpine glacier specific mass balance to climatic changes attributed to the Atlantic Multidecadal Oscillation (AMO). We believe that the specific mass balance is not the appropriate measure to interpret climatic fluctuations. Due to the dynamic response of glaciers to changes in their climatic forcing, the importance of short-term climatic oscillations is overestimated. Taking the changes in glacier geometry into account, the AMO related climate variations are far less important to the recent mass loss than the trend caused by the gradual warming over the past century....

Arizona Weekly Journal Miner : Dec 1901

By: Arizona Pub. Co.

Description: Established in 1864, the Republican Fort Whipple Arizona Miner began as a semimonthly newspaper owned by then Territorial Secretary Richard McCormick and published by Tisdale A. Hand. That same year, McCormick moved the paper to Prescott, the designated capital of Arizona Territory, and bought the very first town-site lot. According to William H. Lyon in Those Old Yellow Dog Days: Frontier Journalism in Arizona, 1859-1912, McCormick established the paper as the creature of the new territorial government. And yet, through the initial rapid succession of editors, the paper tended to avoid political content. Other than announcing Lincoln's reelection as president, the Miner barely noted politics beyond the announcing the meeting of the territorial legislature. All that changed, however, when former prospector John H. Marion took the helm as proprietor and editor of the Miner in 1867. Under his ownership, the paper became a bitter partisan tool. Marion was known for being a proud Democrat, a staunch defender of Arizona, a true frontier editor, and his own man; but Marion was also known to be a heavy drinker with a combative...

Negative Correlation Between Terminal Velocity and Vhf Radar Reflectivity: Observation and Plausible Explanation : Volume 27, Issue 4 (06/04/2009)

By: Y.-h. Chu; I.-y. Lo; C.-l. Su

Description: Institute of Space Science, National Central University, Chung-Li, R.O.C. Taiwan. The correlation between precipitation backscatter P (or radar reflectivity Z) and reflectivity-weighted terminal velocity Vt has long been thought to be positive. Namely, the larger the magnitude of the terminal velocity is, the stronger the radar reflectivity will be, and vice versa. However, we will show in this article the observational evidences of negative VtP correlation made with the Chung-Li VHF radar. It is found that the negative VtP correlation can occur in the regions from close to ground to well above the melting layer. In addition, there is a strong tendency for the negative t–P correlation to occur around the bright band region. In light of the fact that the conventional model of single drop size distribution cannot explain this negative correlation, it is proposed that the drop size distribution responsible for the negative VtZ correlation is composed of two Gamma drop size dist...

A New Southern High-latitude Index : Volume 16, Issue 12 (30/11/-0001)

Description: IFSI/CNR, c.p.27, 00044 Frascati, Rome, Italy. We have developed and examined a new regional geomagnetic index AES-80, defined similarly to the classical auroral electrojet AE index, using data from five Antarctic stations located at corrected geomagnetic latitudes about 80 °S. Because only sparse ground-based information can be derived from auroral latitudes in the Southern Hemisphere, and because no index comparable to AE can be constructed from locations in the south, the possibility of using AES-80 as a measure of high latitudes and polar cap activity is investigated. As a global average activity level indicator, it is found that in general AES-80 gives results rather similar to the classical AE index. However AES-80 provides a more robust measure of the occurrence of high-latitude geomagnetic activity.

An Empirical Model of Global Climate – Part 1: Reduced Impact of Volcanoes Upon Consideration of Ocean Circulation : Volume 12, Issue 9 (13/09/2012)

By: M. Smarte; R. J. Salawitch; N. R. Mascioli; T. Canty

Description: Department of Atmospheric and Oceanic Science, University of Maryland, College Park, MD, USA. Observed reductions in Earth's surface temperature following explosive volcanic eruptions have been used as a proxy for geo-engineering of climate by the artificial enhancement of stratospheric sulfate. Earth cools following major eruptions due to an increase in the reflection of sunlight caused by a dramatic enhancement of the stratospheric sulfate aerosol burden. Significant global cooling has been observed following the four major eruptions since 1900: Santa María, Mount Agung, El Chichón, and Mount Pinatubo, leading IPCC (2007) to state major volcanic eruptions can thus cause a drop in global mean surface temperature of about half a degree Celsius that can last for months and even years. We use a multiple linear regression model applied to the global surface temperature anomaly to suggest that exchange of heat between the atmosphere and ocean, driven by variations in the strength of the Atlantic Meridional Overturning Circulation (AMOC), has been a factor in the decline of global temperature following these eru...
