Investigation Of In-Situ Immobilization Of Contaminated Sediments Using Alginate Gels For The Reduction Of Ecological Risk, Michael V. Podany Mr. Dec 2012

Investigation Of In-Situ Immobilization Of Contaminated Sediments Using Alginate Gels For The Reduction Of Ecological Risk, Michael V. Podany Mr.

Master's Theses

Remediation methods for contaminated sediments include dredging, treatment and disposal and sediment isolation through capping. These methods are costly and adversely impact local ecosystems, in some cases causing major disturbances to the sediment bed and water column. A new remediation technique is proposed for slowly biodegradable contaminants using alginate hydrogels as a binding agent of sediment. The rational is that sediment particles bound in alginate hydrogel are less likely to be resuspended and the treatment is less disruptive than capping. Here we show addition of alginate increased the shear strength of sediment comprised of defined particle sizes. The increase in …

Role Of Tonic Protein Kinase A On Sk2 Channel Expression, Krithika Abiraman Dec 2012

Role Of Tonic Protein Kinase A On Sk2 Channel Expression, Krithika Abiraman

Master's Theses

Small conductance calcium-activated potassium channels (SK) play a fundamental role in synaptic transmission, plasticity, learning and memory (Hammond, 2006; Faber, 2008; Lin et al., 2008) . A very recent study successfully combined single molecule atomic force microscopy (AFM) and toxin pharmacology to quantitatively map SK channels in living neurons (Maciaszek et al., 2012). In addition to localizing native SK channels, this study also showed that SK channel distribution is dynamic with a decrease in SK channel surface expression upon addition of forskolin (FSK), a protein kinase A (PKA) activator. This finding raised further questions about the mechanism through which FSK …

Current Opinion On Nanotoxicology, Ali Pourmand, Mohammad Abdollahi Dec 2012

Current Opinion On Nanotoxicology, Ali Pourmand, Mohammad Abdollahi

Emergency Medicine Faculty Publications

Nanotechnology is one of the premiere technologies available today, having expanded both as field of scientific study and in the public consciousness. Despite this growth, the drawbacks, limitations and potential safety hazards associated with the incorporation of nanotechnology into existing industries are still being learned. The noticeable point is that there is no enough data available yet to analyze global use of nanotechnology from a meta-perspective. Three challenges can be defined in light of nanotoxicology. One, materials that might prove to be significantly toxic must be identified. Two, a system for the categorization of NP materials must be codified and …

Debating Immigration: Arizona's Controversial Response To Illegal Hispanic Immigration, Parker M. Wornall Dec 2012

Debating Immigration: Arizona's Controversial Response To Illegal Hispanic Immigration, Parker M. Wornall

Mahurin Honors College Capstone Experience/Thesis Projects

Hispanic Immigration into the United States is no new phenomena. What is new in regards to this immigration is the strict measures being taken by various states where Hispanic immigration is most prevalent. These laws are proving to be arbitrary, punitive, and unethical. Arizona was the first to pass a “stop policy” on immigration with Senate Bill 1070. This bill does not aptly address the many push and pull factors that have caused this immigration; push factors being factors that will drive people away from Latin America, and pull factors being factors that attract them to the United States. Likewise, …

The Concise Guide To The Modern Calvinist/Arminian Debate, David J. Leonhardt Dec 2012

The Concise Guide To The Modern Calvinist/Arminian Debate, David J. Leonhardt

Mahurin Honors College Capstone Experience/Thesis Projects

The Calvinist/Arminian debate is not a new issue to the Protestant Church; however, it is an issue that has resurged within contemporary Christianity. One major offense committed in this controversial debate occurs when a person or group uses a term from the opposite side in a way that is not the proponent’s original intent or meaning. Furthermore, misconceptions concerning the actual doctrines maintained by either side have become commonplace in the debate. In order to correct this problem, this thesis will serve as a guide for understanding the Calvinist/Arminian debate. It will provide information on the founders of the two …

Nursing Females Are More Prone To Heat Stress: Demography Matters When Managing Flying-Foxes For Climate Change, Stephanie T. Snoyman, Jasmina Munich, Culum Brown

Ecological Impacts of Climate Change Collection

Determining the underlying mechanisms responsible for species-specific responses to climate change is important from a species management perspective. The grey-headed flying-fox, Pteropus poliocephalus, is listed as vulnerable but it also a significant pest species for orchardists and thereby presents an interesting management conundrum. Over the last century, the abundance of the grey-headed flying-fox, P. poliocephalus, in Australia has decreased due to a variety of threatening processes but has increased in abundance in urban areas. These flying-foxes are highly susceptible to extreme heat events which are predicted to increase in the future under climate change scenarios. Exceptionally hot days result in …

Reduced Translocation Of Cadmium From Roots Is Associated With Increased Production Of Phytochelatins And Their Precursors, Mst. Fardausi Akhter, Brian Mcgarvey, Sheila Macfie

Biology Publications

Cadmium (Cd) is a non-essential trace element and its environmental concentrations are approaching toxic levels, especially in some agricultural soils. Understanding how and where Cd is stored in plants is important for ensuring food safety. In this study, we examined two plant species that differ in the distribution of Cd among roots and leaves. Lettuce and barley were grown in nutrient solution under two conditions: chronic (4 weeks) exposure to a low, environmentally relevant concentration (1.0 μM) of Cd and acute (1 h) exposure to a high concentration (5.0 mM) of Cd. Seedlings grown in solution containing 1.0 μM CdCl …

Triterpenes And Steroids From The Leaves Of Aglaia Exima (Meliaceae), K.H. Leong

Research Publications (2011 to 2015)

A study on the leaves of Aglaia exima led to the isolation of one new and seven known compounds: six triterpenoids and two steroids. Their structures were elucidated and analyzed mainly by using spectroscopic methods; 1D and 2D NMR, mass spectrometry, UV spectrometry and X-ray. All the triterpenoids and steroids were measured in vitro for their cytotoxic activities against eight cancer cell lines; lung (A549), prostate (DU-145), skin (SK-MEL-5), pancreatic (BxPC-3), liver (Hep G2), colon (HT-29), breast (MCF-7) and (MDA-MB-231). The new cycloartane triterpenoid, 24(E)-cycloart-24-ene-26-ol-3-one 1, showed potent cytotoxic activity against colon (HT-29) cancer cell line (IC50 11.5 μM).

Interannual Variability Of Wintertime Sea Surface Temperatures In The Eastern Taiwan Strait, Mu-Tun Tzeng, Kuo-Wei Lan, Jui-Wen Chan Dec 2012

Interannual Variability Of Wintertime Sea Surface Temperatures In The Eastern Taiwan Strait, Mu-Tun Tzeng, Kuo-Wei Lan, Jui-Wen Chan

Journal of Marine Science and Technology–Taiwan

Using Advanced Very High Resolution Radiometer (AVHRR) sea surface temperatures (SSTs) at a 1.1-km spatial resolution, we investigated the long-term SST variability in winter in the eastern Taiwan Strait (TS) in 1995~2008. We performed an empirical orthogonal function (EOF) analysis of spatial and time series variances for 15-day mean images. The first three modes in the EOF analysis respectively accounted for 25.9%, 16.61% and 4.59% of variances. In the first mode, the spatial amplitude showed positive values in the northeastern TS and negative values south of Chang-Yuen Rise (CYR). This suggests that warmer water occurred south of the CYR and …
