Numerous flights of Quaternary marine terraces are present around the island of Cyprus, in the Eastern Mediterranean. These terraces are a result of the global eustatic sea-level curve and local tectonism. Marine Isotope Stage (MIS) 5 through MIS 13 terraces are identified, mapped and dated. Palaeoshoreline elevation, an excellent indicator...
The relative rates of hydrogen abstraction from a series of 13
arylmethanes by the trichloromethyl radical were determined at 70°.
The attacking radical was generated from bromotrichloromethane us
ing benzoyl peroxide as the initiator. The solvent was benzenebromotrichloromethane.
An excellent correlation, with a coefficient
of 0.977, was obtained when the...
The emerging use of portable digital devices by students, parents and teachers, is forcing schools to develop real-time communication systems that integrate technology into the general operations of schools, and contemplate governing policies and procedures to sustain and guide the challenges of these new technologies. This study contributes to this...

Electric power needs will only grow over the next decades as more humans ascend from poverty into the middle class. Currently, the majority of electric power is generated by burning fossil fuels. To help mitigate the undesirable effects of burning fossil fuels research is being done to increase the efficiency...
Andic soils (aka Andisols) have unique properties that are important to society. For soil scientists, the genesis and taxonomy of Andisols is often confused because they can form in both volcanic and non-volcanic material. This dissertation seeks to address such confusion by looking at andic soil development in the Cascade...
A series of momochloromethyl arenes and heteroarenes have been reacted
with triphenyltin hydride at 70° C. Under these radical conditions
the only observable reaction is reduction of the starting material to
arylmethane or heteroarylmethane. A significant range of relative rates
(a factor of eighty) has been found among the compounds...
The relative rates of hydrogen atom abstraction from a series of 13 homoaryl
and heteroarylmethanes by the nucleophilic undecyl radical, thermally generated
from lauroyl peroxide, were determined at 70 °C. A reactivity range of 15 was
obtained. Substantial differences in reactivity among isomers were found. The
relative reactivities of the...
Monilinia vaccinii-corymbosi pseudosclerotia overwinter on the soil surface and produce apothecia in early spring, providing primary inoculum for Mummy Berry Disease of blueberry. Burial under 2.5 cm of soil or the absence of light have previously been identified as critical factors preventing the development of apothecia. Mulches were applied to...
