Production, characterization, and applications of biochar from olive processing byproducts
Olive oil production generates several byproducts, including olive mill wastewater, olive pomace, and olive pit. While olive pomace is frequently utilized as cattle feed valued at $10-$50 per ton, this project explores an integrated valorization strategy converting olive pomace into polyphenols, …

Controlled Low-Strength Material (CLSM) produced from limestone fines and other byproducts
Controlled Low Strength Material (CLSM) or flowable fill mixtures are typically specified and used in lieu of compacted fill especially for backfill, utility bedding, void fill and bridge approaches. This study developed flowable fill mixtures containing only quarry fines, fly ash, synthetic gypsum …

EXAMINATION OF VOLATILE ORGANIC COMPOUNDS ASSOCIATED WITH HUMAN DECOMPOSITION BYPRODUCTS IN SOIL
<p>During decomposition, human remains release naturally produced volatile organic compounds (VOCs) that are specific to the process of decay. These VOCs can act as markers that indicate remains are present [1] and presumably can be used to indicate whether or not remains were once present in a …

Oxidation of Disinfection Byproducts and Algae-related Odorants by UV/H₂O₂
… removal of regulated halogenated disinfection byproducts (DBPs) and odorous aldehydic algal byproducts in the presence of geosmin and 2-methylisoborneol, which are earthy-musty odorants that commonly occur in drinking water. UV/H₂O₂ is an expensive advanced oxidation process that is used to …

The effects of crosslinking byproducts on the electrical properties of low density polyethylene
… with Dicumyl Peroxide (DCP), the crosslinking byproducts such as acetophenone, ?-methylstyrene and cumyl alcohol have a significant influence on electrical properties of XLPE power cables. This thesis distinguished the individual contribution of the crosslinking byproducts on space charge …

Formation of Chloroform and Other Chlorinated Byproducts by the Chlorination of Antibacterial Products
Triclosan is a widely used antibacterial agent found in many personal hygiene products. While it has been established that pure triclosan and free chlorine readily react, interactions between triclosan-containing products and free chlorine have not previously been analyzed. Sixteen double-blinded …

Toxic effects on model mammalian cells by monohalogenated disinfection byproducts: haloacetic acids and haloacetonitriles
Disinfection processes provide a necessary barrier against waterborne infectious diseases; yet, water disinfectants inadvertently generate environmentally hazardous chemicals called disinfection by-products (DBPs). While a number of individual DBPs have been found to be mutagenic, cytotoxic, …

Separation And Use Of Oxygenated Byproducts From Non-Catalytically Cracked Triglycerides And Their Methyl Esters
… (SCMEs) if TMEs are cracked. These oxygenated byproducts are substandard fuel components compared to hydrocarbons. However, the SCFAs and SCMEs are valuable as byproducts in a bio-refining scheme. It is therefore desirable to separate and recover these compounds as usable byproducts. </p> <p> …

Removal of selected water disinfection byproducts, and MTBE in batch and continuous flow systems using alternative sorbents.
… the sorption characteristics of six disinfection byproducts (DBPs) on four sorbents. To investigate sorption of volatile organic compounds (VOCs), specially designed experimental batch and continuous flow modules were developed. The investigated compounds included: chloroform, 1,2-dichloroethane …

Gas chromatographic-electron capture analysis of disinfection byproducts from the chlorination of swimming pools and lake water
Trihalomethanes are a class of compounds that are restricted by the Environmental Protection Agency for drinking water. Water sources that contain a high amount of water life increase the amount of trihalomethanes produced when the water is chlorinated. Following the methods utilized by the …

Nuclear magnetic resonance studies of corn zeins and other byproducts of corn wet milling: Dynamic and structural basis of functionality
"Nuclear Magnetic Resonance (NMR) relaxation and spectroscopy techniques were used to evaluate the hydration properties and mobility of ""bound"" water in corn zein solutions and samples of corn gluten meal (CGM) and corn germ meal (CGRM). Multinuclear relaxation measurements using $\sp1$H, $\sp2$H …
