Analysis of toxic and non-toxic Alexandrium (Dinophyceae) species using ribosomal RNA gene sequences
… water of several cargo vessels, and include both toxic and non-toxic strains. An emphasis was placed on the A. tamarense/catenella/fundyense "species complex," a group of morphotypically-similar organisms found in many regions of the world. Two distinct SsrRNA genes, termed the "A gene" and the "B …

Chemical Intimacies and Toxic Publics
In this dissertation, I detail how capitalism has turned pollution into a generally accepted form of violence perpetuated in the name of economic health. Complete with a corps of risk managers and environmental consultants, neoliberal capitalism has fashioned pollution into a universal standard …

Academic Libraries and Toxic Leadership
<p>Toxic leadership has yet to be officially recognized as an area of inquiry in the field of library and information studies. Indeed, the literature on academic libraries is only now beginning to address the topic. None of this should be surprising because leadership, in general, continues to be …

Molecular mechanisms of cadmium toxic
… diseases. However, despite the known toxicity of this metal, there is inconclusive evidence about its mechanism(s) of action in the cells. The present study was therefore undertaken with the aim of defining the role of oxidative stress, intracellular Ca²⁺ alteration via phospholipase …

Toxic urbanism : hearth, heimatlosigkeit, home
In an increasingly toxic world where the average person's body contains 29/35 of the toxins listed on the restricted and hazardous substance list, toxicity is unavoidable. This thesis asks how toxins can re-imagined to become active agents in design. Through the negotiation between hard and soft …

Toxic Gas Sensing on Nanoporous Carbons
<p>Activated carbons, either synthetic, developed in our laboratory, or commercial, were prepared or further modified, in order to introduce specific heteroatoms such as oxygen, nitrogen and sulfur to their matrices. Chips coated with thin layers of the carbon samples were used for the sensing of …

The competitive dynamics of toxic and non-toxic ribotypes of the harmful dinoflagellate Alexandrium tamarense in Scottish waters
… co-occurring in some locations. Shellfish toxicity events may have been in decline in recent years, possibly<br/>due to increasing presence of the benign Group III ribotypes. This thesis investigated the interactions between these two A. tamarense ribotypes. To study these morphologically …

Dye sensitized photooxidation of toxic organic wastewaters
Use of dye sensitized photooxidation is potentially a low cost means of degrading many of the hazardous compounds found in wastewaters. This study investigated the use of methylene blue as a sensitizer to degrade ortho-, meta-, and para-cresol, carbofuran and acrylonitrile. Significant reductions …

Phylogeny and biogeography of the toxic dinoflagellate Alexandrium
… A. universa and A. toxipotens contain all toxic strains, while A. mediterra, A. tamarensis and A. tasmanense contain only non-toxic isolates. Within the minutum group, A. lusitanicum and A. angustitabulatum were also not distinct species based on morphology and phylogeny while A. insuetum …

Fluorescence Detectors for Proteins and Toxic Heavy Metals
<p>An inexpensive detector for proteins is described. The detection technique was based on two-photon excitation intrinsic protein fluorescence using a visible 532 nm diode-pumped nano laser as the excitation source. Proteins that exhibit intrinsic fluorescence must contain at least one tryptophan, …

Kinetic processes and plasma remediation of toxic gases
Regulations on the allowable emissions of toxic gases have resulted in increasing industrial interest in the development of energy efficient methods for remediation. In this work we computationally study the application of Dielectric Barrier Discharges to the remediation of perchloroethylene …

Functional genomics of a non-toxic Alexandrium lusitanicum culture
Paralytic shellfish poisoning (PSP) is a human intoxication associated with the consumption of shellfish contaminated with a family of neurotoxins called saxitoxins. Many species in the dinoflagellate genus Alexandrium have been shown to produce these toxins. Here I report the first case of a …
