Evaluation of Sewage Digested Sludge Conditioning and Dewatering Through Qualitative and Quantitative Laboratory Methodologies Towards Process Monitoring
… characteristics (size, shear viscosity and organic matter composition) affected the most the conditioning and dewatering results but these varied depending on the process conditions i.e. AAD versus CMAD and digestate handling conditions. The reduction in particle size and shear viscosity …

Organic matter structural changes during catagenesis : implications of kerogen chemical structure on petroleum yield and composition.
… of oil formation and controls on petroleum composition. A unique comparison between the chemical changes of fresh algae and preserved algae in black shales during catagenesis, elucidated structural changes of organic matter during preservation and differences between biofuel feedstocks and …

Organic matter fluorescence properties of some U.K. fresh and waste waters
Organic carbon is ubiquitous throughout the aquatic environment. It is an heterogeneous mixture of compounds, some of which are fluorescent, with allochthonous and autochthonous origins. The most common aquatic fluorophores are humic materials (peaks C and A) from degraded plant matter and …

Novel analytical strategies for tracing the organic carbon cycle in marine and riverine particles
Particulate organic carbon (POC) in the ocean and mobilized by rivers on land transfers ~0.1% of global primary productivity to the deep ocean sediments. This small fraction regulates the long-term carbon cycle by removing carbon dioxide from the atmosphere for centuries to millennia. This thesis …

Applied palynology: Multidisciplinary case studies from Egypt, Gulf of Mexico and USA
… as a replacement proxy for some expensive organic geochemical analyses. The ability to detect past hurricane activities and their associated damage to the geologic record is here presented as a new application of palynology. The studied section from northern Egypt is Cenomanian to Turonian …

Assessment of the petroleum generation potential of the Neal Shale in the Black Warrior Basin, Alabama
The Neal shale, the organic-rich interval of the Floyd Shale located in the Black Warrior Basin of Alabama and Mississippi, has attracted recent attention as a potential economic source of hydrocarbons. X-ray diffraction (XRD) and X-ray fluorescence (XRF) spectroscopic analysis of 54 Neal shale …

Primary production of particulate protein amino acids : algal protein metabolism and its relationship to the composition of particulate organic matter
… between algal protein metabolism and particulate organic matter composition. In order to examine biochemical processes associated with conversion of inorganic carbon and nitrogen into protein, the effects of NH+4 limitation on free amino acid and protein composition and incorporation of inorganic …
