Evaluating Microfossil Content Of Dental Calculus From Brazilian Sambaquis, Verônica Wesolowski, Sheila Maria Ferraz Mendonça De Souza, Karl Reinhard, Gregório Ceccantini

Karl Reinhard Publications

To date, limited numbers of dental calculus samples have been analyzed by researchers in diverse parts of the world. The combined analyses of these have provided some general guidelines for the analysis of calculus that is non-destructive to archaeological teeth. There is still a need for a quantitative study of large numbers of calculus samples to establish protocols, assess the level of contamination, evaluate the quantity of microfossils in dental calculus, and to compare analysis results with the literature concerning the biology of calculus formation. We analyzed dental calculus from 53 teeth from four Brazilian sambaquis. Sambaquis are the shellmounds …

A Review Of Existing And Potential New World And Australasian Vertebrate Pesticides With A Rationale For Linking Use Patterns To Registration Requirements, Charles T. Eason, Kathleen A. Fagerstone, John D. Eisemann, Simon Humphrys, Jeanette R. O’Hare, Steven J. Lapidge

United States Department of Agriculture Wildlife Services: Staff Publications

Registration is a necessarily sophisticated evaluation process applied to vertebrate pesticide products. Although conducted to minimize any potential impacts upon public health, the environment and food production, the all-encompassing process of registration can stifle innovation. Vertebrate pesticides are rarely used to control pest animals in food crops. In contrast to agrochemicals, relatively small amounts of vertebrate pesticides are used (50.1%), usually in solid or paste baits, and generally by discrete application methods rather than by broad-scale spray applications. We present a hierarchy or sliding scale of typical data requirements relative to application techniques, to help clarify an evolving science-based approach …

Legitimate Authority, Following Orders, And Wars Of Questionable Justice, David Lefkowitz

Philosophy Faculty Publications

In this article, the author discusses philosophy teacher David Estlund's belief that subjects of a state with a morally justified claim to political authority have a duty to obey its legal commands to wage a particular war, even if they believe that the state has made a mistake in its reasons for waging the war. The author argues that Estlund's theory also allows for individuals to assess the justice of the wars they fight. He also argues that Estlund's view also holds that individual combatants should not be held accountable for any injustice of a war that the state believes …

Antenna Development For Radio Frequency Hyperthermia Applications, Sergio Curto

Doctoral

This thesis deals with the design steps, development and validation of an applicator for radio frequency hyperthermia cancer therapy. An applicator design to enhance targeted energy coupling is a key enabler for preferential temperature increments in tumour regions. A single-element, near-field approach requires a miniaturised solution, that addresses ergonomic needs and is tolerant to patient anatomy. The antenna war-field rriodality and the high-dielectric patient loading introduce significant analytical and computational resource challenges. The antenna input impedance has to be sufficiently insensitive to in-band resonant cletuning and the fields in the tissue can he targeted to selected areas in the patient. …

Bioaugmentation For Improved Recovery Of Anaerobic Digesters After Toxicant Exposure, Anne Schauer-Gimenez, Daniel Zitomer, James Maki, Craig Struble

Biological Sciences Faculty Research and Publications

Bioaugmentation was investigated as a method to decrease the recovery period of anaerobic digesters exposed to a transient toxic event. Two sets of laboratory-scale digesters (SRT = 10 days, OLR = 2 g COD/L-day), started with inoculum from a digester stabilizing synthetic municipal wastewater solids (MW) and synthetic industrial wastewater (WW), respectively, were transiently exposed to the model toxicant, oxygen. Bioaugmented digesters received 1.2 g VSS/L-day of an H₂-utilizing culture for which the archaeal community was analyzed. Soon after oxygen exposure, the bioaugmented digesters produced 25–60% more methane than non-bioaugmented controls (p < 0.05). One set of digesters produced lingering high propionate concentrations, and bioaugmentation resulted in significantly shorter recovery periods. The second set of digesters did not display lingering propionate, and bioaugmented digesters recovered at the same time as non-bioaugmented controls. The difference in the effect of bioaugmentation on recovery may be due to differences between microbial communities of the digester inocula originally employed. In conclusion, bioaugmentation with an H₂-utilizing culture is a …

Stevent: Spatio-Temporal Event Model For Social Network Discovery, Hady W. Lauw, Ee Peng Lim, Hwee Hwa Pang, Teck-Tim Tan

Research Collection School Of Computing and Information Systems

Spatio-temporal data concerning the movement of individuals over space and time contains latent information on the associations among these individuals. Sources of spatio-temporal data include usage logs of mobile and Internet technologies. This article defines a spatio-temporal event by the co-occurrences among individuals that indicate potential associations among them. Each spatio-temporal event is assigned a weight based on the precision and uniqueness of the event. By aggregating the weights of events relating two individuals, we can determine the strength of association between them. We conduct extensive experimentation to investigate both the efficacy of the proposed model as well as the …

Publications

Purpose. This study investigated the effects of simulated visual impairment on nighttime driving performance and pedestrian recognition under real-road conditions.

Methods. Closed road nighttime driving performance was measured for 20 young visually normal participants (M = 27.5 +- 6.1 years) under three visual conditions: normal vision, simulated cataracts, and refractive blur that were incorporated in modified goggles. The visual acuity levels for the cataract and blur conditions were matched for each participant. Driving measures included sign recognition, avoidance of low contrast road hazards, time to complete the course, and lane keeping. Pedestrian recognition was measured for pedestrians wearing either black …

Prediction Of Cognitive Sequelae And Ecological Validity In Critically-Ill Adult Patients, Fu Lye Woon

Theses and Dissertations

Survivors of critical illness have a high prevalence of long-term cognitive and psychiatric morbidity and poor quality of life years after hospital discharge. Data are lacking regarding whether cognitive screening tests predict which critically ill patients may be at risk to develop long-term cognitive sequelae and whether cognitive sequelae predict the patients everyday functioning. This study sought to determine whether cognitive screening tests, including the Mini-Mental State Examination (MMSE) and Mini-Cog, predict long-term cognitive sequelae and everyday functioning in survivors of critical illness 6-month post-hospital discharge. A second purpose was to investigate whether cognitive sequelae are associated with poor everyday …

Lidar Remote Sensing Variables Predict Breeding Habitat Of A Neotropical Migrant Bird, Scott J. Goetz, Daniel Steinberg, Matthew G. G. Betts, Richard T. Holmes

Dartmouth Scholarship

A topic of recurring interest in ecological research is the degree to which vegetation structure influences the distribution and abundance of species. Here we test the applicability of remote sensing, particularly novel use of waveform lidar measurements, for quantifying the habitat heterogeneity of a contiguous northern hardwoods forest in the northeastern United States. We apply these results to predict the breeding habitat quality, an indicator of reproductive output of a well-studied Neotropical migrant songbird, the Black-throated Blue Warbler (Dendroica caerulescens). We found that using canopy vertical structure metrics provided unique information for models of habitat quality and spatial patterns of …

Lesbian Mothers & Gay Fathers: Overt And Subconscious Homophobic Biases Concerning Parental Fitness, Jude Hall

Dalhousie Journal of Legal Studies

Disputes in family law, particularly in child custody and access cases, often involve emotionally charged parties. These parties, when pitted against one other in an adversarial system, often seek to discredit, impugn or malign the opposing party in an effort to influence an outcome in their favour. The judiciary, as the triers of fact and arbiters in these cases, must consider the often widely divergent positions of each party, and apply an impartial analysis and judgment that considers the best interests of the children at the centre of these disputes. Despite the presumption of judicial impartiality, it is reasonable to …

Vaccine-Related Injuries: Why Canada Needs To Adopt A No-Fault Compensation Scheme In Light Of The New H1n1 Vaccine, Erin Fowler

Dalhousie Journal of Legal Studies

On June 11, 2009, the World Health Organization (“WHO”) declared the H1N1 influenza a pandemic. H1N1 is a strain of the influenza virus that, in the past, usually only affected pigs. In the spring of 2009, it emerged in people in North America. This is a new strain of influenza, and because humans have little to no natural immunity to this virus, it can cause serious and widespread illness. As of November 1, 2009, there were more than 440 000 laboratory-confirmed worldwide cases of pandemic influenza H1N1 and over 6000 deaths reported to WHO. In late October, the H1N1 vaccine …

In Situ Development Of Western Prairie Fringed Orchid Seeds, Protocorms, And Seedlings In Grazed And Non-Grazed Prairie Habitat, Bonnie Warner Alexander, Donald Kirby, Mario Biondini, Edward Dekeyser

The Prairie Naturalist

In 1989, the U.S. Fish and Wildlife Service listed the western prairie fringed orchid (Platanthera praeclara) as threatened. Although this orchid has been monitored for years, there is little scientific documentation of its biology, ecology, and phenology, nor the impacts of management activities on its populations. Our objectives were to document seed germination and seedling production rates after one year in situ, and compare seed germination in grazed and non-grazed prairie habitat in the Sheyenne National Grassland (SNG) in southeastern North Dakota. Of 18,717 planted seeds, we recovered 1,561 swollen embryos, 94 protocorms, and 51 seedlings. We documented no difference …

Ring-Necked Pheasant Nest Parasitism Of Sharp-Tailed Grouse Nests In Southwest North Dakota, Benjamin A. Geaumont, Kevin K. Sedivec, Christopher S. Schauer

The Prairie Naturalist

Numerous investigators have reported observations of ring-necked pheasant (RNP; Phasianus colchicus) eggs in nests of other gamebirds and waterfowl species (Errington and Hamerstrom 1938, Westemeier et al. 1998, Hagen et al. 2002, Krakauer and Kimball 2009). Previously recorded hosts include wild turkey (Meleagris gallopavo; Schmutz 1988), northern bobwhite (Colinus virginianus; Westemeier et al. 1989), greater prairie-chickens (Tyrnpanuchus cupido; Westemeier et al. 1998), and lesser prairie-chickens (T. pallidicinctus; Hagen et al. 2002). The reported occurrence of nest parasitism during these studies has generally been low with the highest reported occurrences found in …

Early Winter Feeding On Elm Bark By Eastern Fox Squirrels Near The Western Range Terminus, Dessa K. Montgomery, Raymond S. Matlack

The Prairie Naturalist

Fox squirrels (Sciurus niger) feed on >30 different types of food across their extensive range ~Korschgen 1981) including tree buds, flowers, fruits, seeds, and, on occasion, bark. For a large portion of the year, fox squirrels rely heavily on tree seeds (Koprowski 1991). For three consecutive years (2007-2009), we observed fox squirrels feeding on bark of elm trees ( Ulmus sp.) on the campus of West Texas A&M University, Canyon, Texas. Squirrels began feeding on bark in late November shortly after leaves had fallen off the trees and continued almost daily throughout the winter. In late February, when …
