Buskirk, Reid Ezekiel (2021-12-16)The coupled processes of biogeochemical and hydrological processes in hyporheic zones (HZ) commonly determine the fate of contaminants in both groundwater and surface water. Many parts of the HZ experience both transient ...
-
Wang, Xiao (2022-08-25)Activated iron media has been proven effective for treating a variety of environmental contaminants with more strengths and less drawbacks comparing to conventional zero-valent iron (ZVI) technology. Despite its success, ...
-
Arteaga, Stacy E (2013-02-28)Aflatoxins are potent carcinogens produced by fungi Aspergillus flavus and Aspergillis parasiticus. Aflatoxins are able to contaminate different crops. Once ingested in the body, aflatoxins are able to cause harmful effects ...
-
Pitre, Brandon (2012-12-04)The purpose of this study was to implement a new, rapid field method to effectively and accurately detect harmful clay minerals in aggregate fines by using the modified methylene blue (MMB) test. The focus of this study ...

Atomistic Modeling of Interactions Between Minerals and Organics in Civil Infrastructure Materials Grajales Saavedra, Javier Aurelio (2020-03-26)This document comprises a sum of research efforts aimed at the discovery of mechanisms of interaction between mineral (inorganic), and organic substances used or occurring in civil infrastructure materials. This endeavor ...
-
Sousa, Brittany Nicole (2017-02-17)Mycotoxin contamination of grains is a serious global problem with feed stocks often being contaminated with multiple, different mycotoxins. Many studies have successfully isolated microorganisms or used chemical and ...
-
Chorghe, Darpan Atul (2017-04-21)One promising strategy to manage the large volumes of water needed for and wastewater generated by hydraulic fracturing is on-site treatment and reuse. In particular, the saline flowback water contains many of the chemicals ...
-
Marroquin-Cardona, Alicia 1979- (2011-05-10)Aflatoxins are toxic metabolites produced by Aspergillus flavus and A. parasiticus fungi. Aflatoxin B1 (AFB1) is the most toxic and is a potent carcinogen with antinutritional and immunosuppressive effects. Several natural ...
-
Gonzalez, Esteban (2023-05-04)The proliferation resistance analysis of re-processing and re-enriching spent uranium fuel discharged from a Canadian Deuterium Uranium (CANDU) reactor with regards to the accumulation of 236U and 238Pu was conducted. ...
-
Russell, George 1983- (2012-11-28)Expansive clay mineral contamination of road aggregate materials in Texas is a persistent problem. Hydrous layer silicate minerals - particularly smectites - in concretes are associated with decreased strength and durability ...
-
Liu, Lian (2013-08-14)Bentonite clays have long been used as additives in animal feed, aiming to improve pellet quality and prevent caking. Certain bentonites are also capable of deactivating aflatoxin B_(1) (AfB_(1)) in feed by adsorption, ...
-
Ivanishin, Igor (2020-12-01)Dolomitic reservoir rocks of different age, origin, and composition were analyzed using several techniques, including: powder X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning electron microscopy (SEM), ...
-
Musharova, Darya (2012-07-16)Clays which exist in formations in the vicinity of injection and disposal wells is a worldwide problem in the petroleum industry. Clays can be categorized as two major groups: swelling clays, which include smectite group ...
-
Barrientos Velazquez, Ana Luisa (2015-12-01)Aflatoxins are toxic secondary fungal metabolites that are present in a variety of crops. Numerous animal experiments have demonstrated the effectiveness of smectite clay in adsorbing aflatoxin and in reducing the toxicity ...
-
Howard, Keya J. (2016-12-06)Sections of streams located downstream from dairy farms and wastewater treatment plants (WWTPs) in central Texas are listed on the 303 (d) List of Impaired Waters due to bacterial contamination (possibly due to fecal ...
