The photodebromination of selected bromoarenes has been studied at 300 nm
to determine the the possible mechanistic pathways leading to product.
Irradiation of 4-bromobiphenyl (BpBr) at this wavelength leads to the product
biphenyl. The quantum yield of intersystem crossing (0.98) and quenching
studies with cis-1 ,3-pentadiene suggest that the reaction...
Escherichia coli double-strand uracil-DNA glycosylase (Dug) was purified to apparent homogeneity from bacteria that were defective in uracil-DNA glycosylase (Ung). After cloning the dug gene, recombinant Dug was overexpressed, purified, and characterized with respect to activity, substrate specificity, product DNA binding, and mechanism of action. Purified Dug excised both uracil...
Multiobjective Decision Making (MODM) has been
suggested for the solution of complicated decision
problems. Decision analysis in numerous areas, including
industrial energy and environmental planning, necessarily
requires consideration of multiple conflicting
objectives. MODM has been successfully applied to
a number of these problems of this type. Moreover, it
has the...
Herring is an important stock as bait for lobster fisheries and a component of the food web of the Northwest Atlantic Ocean. However, herring is very vulnerable to environmental variables such as temperature, food supply, and to the type of sediment on the bottom floor. Egg and larval stage herring...
