Dissolved arsenic typically results from chemical weathering of arsenic rich sediments and is most often found in oxidized forms in surface water. The mobility of arsenic is controlled by its valence state and also by its association with iron oxides minerals, the forms of which are both influenced by abiotic and biotic processes in aqueous environment. In this study, speciation methods were used to measure and confirm the presence of reduced arsenic species in the surface water of Frenchman creek, a gaining stream that crosses the Colorado- Nebraska border. Selective extraction analysis of aquifer and stream bed sediments shows that …

Diversification Of Angiosperms During The Cretaceous Period, Sakia Fields
Department of Environmental Studies: Undergraduate Student Theses
The topic of the Angiosperms relatively sudden appearance and diversification is a topic that has puzzled plenty of biologists and is even referred to as an “abominable mystery” by Charles Darwin. Up to date, many hypotheses have been proposed using various forms of data to form them. The available knowledge used to evaluate this topic has changed over the years, which has created some theme shifts. Some of the best supported of these hypotheses are more recent, but this does not make older articles unworthy of being evaluated, as they still often have relevant information. In the past, their appearance …

How Is Remote Sensing Being Used To Prevent Wildfires Today?, Luke Lauby
Department of Environmental Studies: Undergraduate Student Theses
Wildfires frequencies and severities are on the rise. To properly combat and contain them, artificial intelligence should be utilized. An in-depth literature review was conducted in order to evaluate the current state of artificial intelligence specifically relating to wildfire prevention and suppression efforts. The findings in this research sheds further light on the helpful implications that these technologies (both satellites and UAVs) do, and can have on wildfire suppression. If further adopted in wildfire suppression efforts, artificial intelligence can play a more effective role. Through this, fires can become better prevented, more controllable, and better understood using modern technology.

The Effect Of Agkistrodon Contortrix And Crotalus Horridus Venom Toxicity On Strike Locations With Live Prey, Chase Giese
Department of Environmental Studies: Undergraduate Student Theses
This paper aims to uncover if there is a significant difference in the strike location of snake species that have different values of LD50% venom. It is thought that most snakes strike their prey in the anterior (head) area in order for their venom to work quicker in killing them. Venom toxicity is measured by its LD50% value, which is the amount of venom, in mg/kg, to kill 50% of a test population. The Copperhead has an LD50% value of 10.9 mg/kg, and the Timber Rattlesnake has an LD50% value of 1.64 mg/kg. The hypothesis was that if venom toxicity …

Evaluating The Feed-In Tariff Policy In The Philippines, Joyce Marie P. Lagac, Josef Teofisto T. Yap
Ateneo School of Government Publications
To address the problems of climate change and energy security; the Philippines enacted the Renewable Energy (RE) Act of 2008. The law mandated the Feed-In Tariff (FiT) policy; which was designed to provide a guaranteed fixed price to RE investors for 20 years to develop renewable technology. This paper aims to evaluate the effectiveness of the FiT policy in promoting renewable energy development in the Philippines by assessing its costs and benefits. Data show that while the FiT has led to an increase in RE generating capacity; the share of renewable energy in the country has been declining since 2011. …
