Effect of pyridine triphenyl borane (KH101) on the reproduction of Calanoid Copepod, Acartia omorii Bradford

Creator:: Hossain, Md. Khaled, Ishimaru, Takashi, and Takeda, Seiichi
Abstract:: Currently documented that pyridine triphenyl borane (KH101) is possible to use as an alternative of tributyltin based antifouling biocide in coastal and marine environment. But its impact on marine life especially on smaller zooplankton is so far unknown. The present study was conducted to determine the effect of KH101 on...

Microbial communities from methane hydrate-bearing deep marine sediments in a forearc basin

Creator:: Reed, David W., Fujita, Yoshiko, Delwiche, Mark E., Blackwelder, D. Brad, Sheridan, Peter P., Uchida, Takashi, and Colwell, Frederick
Abstract:: Microbial communities in cores obtained from methane hydrate-bearing deep marine sediments (down to more than 300 m below the seafloor) in the forearc basin of the Nankai Trough near Japan were characterized with cultivation-dependent and -independent techniques. Acridine orange direct count data indicated that cell numbers generally decreased with sediment...

Immune responses of juvenile chinook salmon (Oncorhynchus tshawytscha) to p,p-̓DDE and tributyltin

Creator:: Misumi, Ichiro
Abstract:: In this thesis, we examined the effects of the exposures to anthropogenic pollutants on the fish, primarily juvenile chinook salmon, immune system using newly and recently developed immune assays. In addition, we developed a new assay for measuring immunocompetence of fish. In the first chapter, the Alamar Blue assay was...

Central control of locomotor activity in juvenile salmonids : the role of corticotropin releasing hormone in the brain

Creator:: Clements, Shaun
Abstract:: The present study investigated the neurocrine and neuroendocrine control of locomotor activity, habitat choice, social behavior, and migratory behavior in juvenile chinook salmon (Oncorhynchus tshawytscha). This was achieved by the manipulation of three neurotransmitter systems; serotonin (5-HT), dopamine (DA), y-amino-n-butyric acid (GABA) and the neuropeptide corticotropin-releasing hormone (CRH). Chemicals were...

Biologically active cyclic depsipeptides from marine cyanobacteria

Creator:: Medina, Rebecca A.
Abstract:: This thesis describes the chemical investigation of marine cyanobacteria collected in Madagascar and Panama with an emphasis on the isolation and structure elucidation of medicinally relevant secondary metabolites. A collection of the marine cyanobacterium Lyngbya majuscula from the Radames Islands, Madagascar yielded two new cyclic depsipeptides, radamamides A and B,...

Heavy fermion effective mass in the superconducting vortex state

Creator:: Townsend, Emily A.
Abstract:: The extended-Lifshitz-Kosevitch formalism (ELK) unifies the treatment of the de Haas-van Alphen (dHvA) effect, allowing it to transcend its traditional roles of mapping Fermi surfaces and measuring effective masses. Here we exploit the capabilities of dHvA as a probe of many-body effects to examine heavy-fermion su- perconductivity. ELK successfully describes...

Endogenous and antiviral RNA silencing pathways in Arabidopsis

Creator:: Chapman, Elisabeth J.
Abstract:: RNA silencing pathways are required for a wide variety of processes in most eucaryotes. In plants, small-interfering RNA (siRNA) arising from transposons and other repetitive sequences is associated with heterochromatin formation and maintenance. MicroRNAs and trans-acting siRNAs encoded at discrete loci function as negative regulators of gene expression by triggering...

Studying fusion reactions for effect of PCN on heavy nucleus formation and for nuclear structure effects

Creator:: Naik, Radhika
Abstract:: The fusion reaction ²⁰⁸Pb (⁵⁰Ti, xn) ²⁵⁸⁻x Rf (x = 1-3) was studied to determine PCN (probability that the mononucleus system evolves to form a compound nucleus inside the fission saddle point) and to establish the value of Wsur (survival probability) for the given reaction experimentally. The fission excitation function...

A Public Elementary School as a Cultural Context : Japanese Children Learning to Perceive their Environment

Creator:: Sugai, Taichi
Abstract:: This thesis examines the cultural context in which Japanese children are constructing their own perspective of the environment because in the development of environmental education in Japan, the perspectives of children and teachers have not been taken into consideration. Although educators have made efforts to give direction to environmental education,...
