Degradation Of Halogenated Aliphatic Compounds In Sequential Anaerobic
… in-situ) leads to an accumulation of daughter compounds (cDCE, VC) which are more toxic than their parent compounds (PCE, TCE). Furthermore, PCE is resistant to degradation in aerobic environments while VC and cDCE are readily oxidized co-metabolically by aerobic methanotrophic bacteria, among …

The urea adducts of certain esters containing twenty carbons
… complexes with many straight-chained organic compounds. So selective is the formation of these complexes with linear aliphatic compounds that it provides a means of separation form the analogous branched and cyclic compounds. Linear esters derived from normal saturated and unsaturated esters …

Characterizing the role of ATP-binding cassette transporters in triterpenoid wax bloom production
… and especially the transport of wax bloom compounds to the leaf surface have yet to be fully elucidated. Numerous ATP-binding cassette (ABC) transporters have been characterized in model systems and crops, and some members of the G transporter subfamily are linked to the production of …

Urea adducts of the esters of stearic acid
… cyclic hydrocarbons and their derivatives. The compounds are stable enough to be used in separating these types of aliphatic compounds from their branched and cyclic analogs. Linear esters derived from normal saturated acids give adducts as expected. Urea complexation was found to be of great …

Poliaminas em amostras biológicas humanas: importância e métodos de detecção.
Polyamines are basic aliphatic compounds belonging to the list of bioactive amines and have important metabolic and physiological functions in animals, plants and microorganisms . They are an important target for the development of chemotherapy, since they are intimately involved in the processes …

Evaluation of gasoline-denatured ethanol as a carbon source for wastewater denitrification
… a lower grade material that contains mostly aliphatic compounds, but lacks the components that normally boost the octane rating, such as benzene, toluene, ethylbenzene and xylenes (BTEX). Herein are presented the results of using dEtOH, EtOH (95.5% ethanol-4.5% water) and MeOH for …

Molecular Encapsulation in Kinetically Trapped, Hydrogen-Bonded Pyrogallolarene Hexamers
… of a variety of molecules. Aromatic and aliphatic compounds have particularly high guest loading within the hexamers and often result in kinetically stable guest-filled capsules in solution.</p> <p>Kinetic studies of the encapsulation complexes of anthracene, biphenyl, fluoranthene, …

Mechanisms of Microbial Methane Production from Sub-Bituminous Australian Coal
… from the LSCM was found to contain long chain aliphatic compounds ranging from C11 to C27 and aromatic compounds, such as methylated naphthalenes, fluorene and phenanthrene. When treated with oxidative chemicals and enzymes mimicking microbial coal degradation, compounds such as acetate, …

Chalcones derived from m-nitroacetophenone
The object of this research was to prepare substituted derivatives of various chalcones having the nitro group substituted in the 3<sup>1</sup>-position, the idea being to help complete the series of chalcones having the nitro group in that position. This was to be done by condensing various …

Lipoxygenase activity in menhaden (Brevoortia tyrannus) and its contribution to oxidation of omega-3 polyunsaturated fatty acids in menhaden oil
… the TBA values of the esters. Of the 60 volatile compounds identified by GC-MS in the undeodorized menhaden oil, 19 were aldehydes, 9 were alcohols and 8 were ketones. Volatiles that are potentially Ii poxygenase derived, namely 2-octenal, 1-octen-3-01, 2-nonenal, 2,6-nonadienal (E,Z), and …

An analysis of the methyl rotation dynamics in the So (x' A) and T (a A) states of thioacetaldehyde from Pyrolysis jet spectra /
Jet-cooled, laser-induced phosphorescence excitation spectra (LIP) of thioacetaldehyde CH3CHS, CH3CDS, CD3CHS and CD3CDS have been observed over the region 15800 - 17300 cm"^ in a continuous pyrolysis jet. The vibronic band structure of the singlet-triplet n -* n* transition were attributed to the …
