Estimating Seasonal And Diurnal Variations In Influent Wastewater Characteristics For Optimization Of Activated Sludge System In A Northern Community, Ameet John Pinto

Engineering

Influent characterization experiments were carried out at the wastewater treatment facility in Fairbanks, Alaska. These experiments were carried out to trace the diurnal and seasonal variations in the influent flow and organic loading rates. A considerable difference in the wastewater flow and organic loading rates was -seen on a seasonal as well as a diurnal basis. The project hypothesized that better understanding of broad influent diurnal and seasonal variations in a wastewater-treatment facility can help optimize control strategies. Based on the observed variations, oxygen production and supply was analyzed as an avenue for optimization in the high purity oxygen activated …

The Genome Of A Saxitoxin-Producing Cyanobacterium, Andrew Lee Krohn

Chemistry and Biochemistry

Saxitoxin, the causative agent of paralytic shellfish poisoning, is produced by dinoflagellates and cyanobacteria, the latter being a far simpler organism at the genomic level. In order to establish a baseline for future research into saxitoxin biosynthesis, we sought to determine the genomic complexity of the saxitoxin-producing cyanobacterium, Anabaena circinalis strain ACBU02, relative to the published genome of its non-toxic analogue, Anabaena sp. PCC 7120. Total conservation of genomic organization was represented in less than 10 percent of end-sequenced DNA clones from restriction digestion libraries. Ninety percent of sequences contained highly homologous regions indicating a high degree of conservation among …

Heavy Metal Tissue Distributions In Southwestern Alaskan Waterfowl: Total Mercury Assays From Muscle, Brain, And Bone, Roger F. Rothschild

Chemistry and Biochemistry

Food containing mercury has been identified as a possible health risk. Total mercury (THg), which is inorganic (Hg²), and methylmercury (MeHg) species, has been found in the arctic food web. In Alaska, birds are an important seasonal component of the diet, but have not been studied extensively and characterized for the presence of mercury. Birds are good subjects for examination because they feed at different trophic levels, can be long-lived, and are both abundant and widely distributed. Not only can birds monitor local Alaskan food webs, but, if they are migratory, can be used to compare exposure in different regions. …

Src-Dependent Tyrosine Phosphorylation At The Tips Of Growth Cone Filopodia Promotes Extension, Estuardo Robles, Stephanie Woo, Timothy M. Gomez

Neuroscience: Faculty Publications

Extracellular cues guide axon outgrowth by activating intracellular signaling cascades that control the growth cone cytoskeleton. However, the spatial and temporal coordination of signaling intermediates remains essentially unknown. Live imaging of tyrosine phosphorylation in growth cones revealed dynamic phospho-tyrosine (PY) signals in filopodia that directly correlate with filopodial behavior. Local PY signals are generated at distal tips of filopodia during extension and are lost during retraction. Active Src family kinases localize to the tips of filopodia, and Src activity regulates both filopodial dynamics and local PY signaling. Positive guidance cues stimulate filopodial motility by locally increasing tyrosine phosphorylation in a …

Dux, Rick Barent, Jayanta Sinha, Mark Gouthro, Todd Swanson, Ardis Barthuli, Mehmet İnan, John T. Ross, Leonard A. Smith, Theresa J. Smith, Robert Webb, Bonnie Loveless, Ian Henderson, Michael M. Meagher

Papers in Biochemical Engineering

A recombinant C-terminus heavy chain fragment from Botulinum neurotoxin serotype E (BoNT/E) is proposed as a vaccine against the serotype E neurotoxin. This fragment, rBoNTE(Hc), was produced intracellular in Pichia pastoris GS115 by a three-step fermentation process, i.e., glycerol batch phase and a glycerol fed-batch phase to achieve high cell densities, followed by a methanol fed-batch induction phase. The rBoNTE(Hc) protein was purified from the soluble fraction of cell lysates using three ion-exchange chromatography steps (SP Sepharose Fast Flow, Q Sepharose Fast Flow, Sp Sepharose High Performance) and polished with a hydrophobic charge induction chromatography step (MEP HyperCel). Method development …

Trophic Relationships In An Arctic Marine Foodweb And Implications For Trace Element Dynamics, Larissa-A Dehn

Biological Sciences

Tissues of subsistence-harvested Arctic marine and terrestrial mammals and potential prey species were analyzed for isotopes of carbon and nitrogen and selected trace elements describing contaminant pathways in the food web. Feeding habits of ice seals were characterized using stable isotopes and gastric contents analysis. Bearded seals (Erignathus barbatus) relied on the benthic food chain. Zooplankton and fishes were significant prey for ringed seals (Phoca hispida), while fishes were the principal prey in spotted seals (Phoca largha). Gastric prey composition and isotope ratios varied with age and sex. Effects of age, trophic level, and prey prevalence on trace element concentrations …

A Case/Control Analysis And Comparison Of Indoor Air Quality In Alaskan Homes, Satish Dinakaran

Engineering

Indoor Air Quality (IAQ) parameters such as CO, CO₂, relative humidity, temperature, radon, particulate matter, formaldehyde, benzene, toluene, hexane, Total Volatile Organic Compounds (TVOC) and microbial matter were monitored before and after remediation in 36 low-income homes in Alaska (Hooper Bay and Fairbanks). The objective was to see if there was any improvement in IAQ with remediation. Hooper Bay homes had significantly higher levels of CO₂ and relative humidity compared to Fairbanks homes both before and after remediation. There was a general reduction in CO₂ with remediation, although it was not statistically significant. When IAQ in two moderate-income homes in …

Assessment Of Formation Damage From Drilling Fluids Dynamic Filtration In Gas Hydrate Reservoirs Of The North Slope Of Alaska, Prasad B. Kerkar

Engineering

Gas hydrates in the Alaska North Slope, with a potential of 590 TCF gas-in-place near existing infrastructures of Prudhoe Bay, Kuparuk River and Milne Point Units, have sparked interest among unconventional energy experts. Drilling through gas hydrates has always been critical as a source of heat into the formation, leading to dissociation of hydrates. Moreover, the recent drive toward open hole completions and highly deviated or horizontal wells have emphasized the need for evaluation of drilling or completion fluids suitability from a perspective of formation damage. A significant decrease in well productivity near the well-bore can occur due to the …

Changes In Embryonic Development, Hatching, And Zoeae Of Snow Crab With Variation In Incubation Temperature, Joel Benjamin Webb

Fisheries

The effect of incubation temperature on duration of embryonic development and morphology, weight and energetic content of post-hatch zoeae was described for snow crab, Chionoecetes opilio, from the eastern Bering Sea held at -1, 0, 1, 3, and 6° C in the laboratory from collection to hatch. The mean incubation time increased with decreasing temperature by 32% (113 d) between 6 and -1° C. Extrusion success of females at 6° C was lower versus 0 or 3° C, but the duration of hatching did not vary significantly with incubation temperature. A one-year cycle of embryo incubation was observed, indicating that …

Monitoring Stress Hormones In Rehabilitated And Captive Otariids, Lisa Petrauskas

Marine Biology

Cortisol and corticosterone are the primary mammalian stress hormones released in response to a perceived stressor. Cortisol is rapidly metabolized in the blood, while corticosterone is the dominant product in fecal material. Radioimmunoassay procedures to measure fecal corticosterone and serum cortisol in California sea lions were validated, and adrenal response to surgical and non-surgical procedures was assessed. Other objectives included seasonal and behavioral variability in fecal corticosterone concentrations in captive Steller sea lions, as well as adrenal response to various stressors of a rehabilitated Steller sea lion. There was a significant (P ... 0.05) adrenal response for rehabilitated California sea …

Metabolic Hormone Levels And Immunocompetence Of Neonatal Harbor Seals (Phoca Vitulina) In Rehabilitation Settings Compared To Wild Harbor Seal Pups, Danielle Renee O'Neil

Marine Biology

Health of harbor seal pups in rehabilitation and in the wild were compared using two metabolic hormones (cortisol and total thyroxine, TT4), two cellular immunity components (lymphocytes and eosinophils) and morphometric measurements. Neonatal harbor seals in two rehabilitation facilities were compared to wild harbor seal pups. Permanently captive harbor seals housed at the Alaska SeaLife Center were also studied. High levels of cortisol at weaning suggest changes in the stress response may be due to diet adjustments in pups during rehabilitation. The lower cortisol concentrations post-weaning suggest that pups in rehabilitation had overcome the challenge of pre-weaning diet, handling or …
