Linden (Tilia cordata) associated bumble bee mortality : metabolomic analysis of nectar and bee muscle

Creator:: Lande, Claire, Rao, Sujaya, Morre, Jeffrey T., Galindo, Gracie, Kirby, Julie, Reardon, Patrick N., Bobe, Gerd, and Stevens, Jan Frederik
Abstract:: Linden (Tilia spp.), a profusely flowering temperate tree that provides bees with vital pollen and nectar, has been associated with bumble bee (Bombus spp.) mortality in Europe and North America. Bee deaths have been attributed, with inadequate evidence, to toxicity from mannose in nectar or starvation due to low nectar...

Microcomputer-based fluorometric kinetic determination of ascorbic acid and flow injection analysis methods for interference correction and kinetic determinations based on the peak profile

Creator:: Chung, Hyung-Keun
Resource Type:: Dissertation
Full Text:: microcomputer-based data acquisition and control system for dynamic fluorometric measurements was developed

Microcomputer controlled chemical and radiochemical separations and analysis

Creator:: Bennett, Casey Wayne
Abstract:: An automated radiochemical flow analysis (ARFA) system was developed which integrates chemical and radiochemical techniques into one system through the use of a microcomputer. The operator, through the microcomputer, controls valves and pumps to transfer sample and reagent solutions to counting loops, ion exchange columns and holdup reservoirs. A Ge(Li)...

Fusion enhancement with neutron-rich radioactive beams

Creator:: Zyromski, Kristiana Elizabeth
Abstract:: Fusion reactions with radioactive neutron-rich projectiles have been the subject of much recent theoretical and experimental interest. Predictions of enhancement of the cross section due to the use of a neutron-rich projectile may have implications for synthesis of heavy nuclei. In this work, the fusion-fission excitation functions were measured for...

Gaseous electron-diffraction investigations : I. Development of high-temperature nozzles : II. Molecular structure and barrier to internal rotation of diboron tetrafluoride and diboron tetrabromide : III. Molecular structure and composition of 2,3-butanedione and oxalyl chloride at high temperature

Creator:: Danielson, Donald Delbert
Abstract:: The design and construction of two new sample injection systems or nozzles, for use with the Oregon State electron diffraction apparatus are discussed. One of these nozzles was intended for use with volatile samples the vapors of which were to be heated or cooled over the range -196 to 540°C;...

Elemental abundances in the silicate phase of pallasitic meteorites

Creator:: Cooper, Thurman Dale
Abstract:: The silicate phases of 11 pallasites were analyzed instrumentally to determine the concentrations of some major, minor, and trace elements. The silicate phases were found to contain about 98% olivine with 1 to 2% accessory minerals such as lawrencite, schreibersite, troilite, chromite, and farringtonite present. The trace element concentrations, except...

Analysis of fourteen trace elements in Saudi Arabian layered gabbros by radiochemical neutron activation analysis

Creator:: Palmer, Curtis Allyn
Abstract:: Eight layered gabbro samples from two layered complexes, two xenoliths, one basalt from a hot brine area and a standard basalt rock (BCR-1) were analyzed by RNAA (radiochemical neutron activation analysis) for 14 trace elements, Au, Ni, Co, Ag, Sb, Se, Zn, In, T1, Rb, Cs, U, Ba and Sr....

Abiotic and biological transformation of TBOS and TKEBS, and their role in the biological transformation of TCE and c-DCE

Creator:: Vancheeswaran, Sanjay
Abstract:: At Site-300, Lawrence Livermore National Laboratory (LLNL), CA, trichloroethene (TCE) is present along with tetraalkoxysilanes such as tetrabutoxysilane (TBOS) and tetrakis(2-ethylbutoxy) silane (TKEBS), as subsurface contaminants. Intrinsic transformation of TCE to cis-dichloroethene (c-DCE) was observed in the groundwater at locations co-contaminated with TBOS or TKEBS. Attenuation of TBOS and TKEBS...

The preparation of 2-methoxy-4,5-dimethylstilbene and its photochemistry

Creator:: Tong, Homer Hin-Chau
Abstract:: During a study of the abnormal dienone-phenol rearrangement discovered by Marvell and Geiszler, Imel (1960) found that 4-oxo-3,3-dimethyl-3,4-dihydrophenanthrene rearranged slowly to a phenol which was tentatively identified as 3,4-dimethyl-l-phenanthrol; further evidence to support this assignment was deemed essential. The recent work by Mallory on the photochemical conversion of stilbenes to...
