Zoonotic potential of Giardia duodenalis and Cryptosporidium spp. and prevalence of intestinal parasites in young dogs from different populations on Prince Edward Island, Canada
No full textThe prevalence of Giardia duodenalis, Cryptosporidium spp. and other intestinal parasites was determined in dogs <1 year old from Prince Edward Island, Canada. Fecal samples were collected from the local animal shelter (n=62), private veterinary clinics (n=78) and a pet store (n=69). Intestinal parasites isolated included G. duodenalis, Cryptosporidium spp., Toxocara canis, Isospora spp. and Uncinaria stenocephala. To estimate the zoonotic risk associated with these infections, genotypes of G. duodenalis and Cryptosporidium spp. were determined using 16S rRNA and Hsp70 gene sequencing, respectively. Dogs from the pet store had the highest prevalence of intestinal parasites (78%, 95% CI: 68-88%), followed by the private veterinary clinics (49%, 95% CI: 37-60%), and the local animal shelter (34%, 95% CI: 22-46%). The majority G. duodenalis belonged to host-adapted assemblages D (47%, 95% CI: 31-64%) and C (26%, 95% CI: 13-43%), respectively. Zoonotic assemblages A and B were isolated alone or in mixed infections from 16% (95% CI: 6-31%) of G. duodenalis-positive dogs. All Cryptosporidium spp. were the host-adapted C. canis. While host-adapted, non-zoonotic G. duodenalis genotypes were more common, the presence of G. duodenalis assemblages A and B, T. canis, and U. stenocephala suggests that these dogs may present a zoonotic risk. The zoonotic risk from Cryptosporidium-infected dogs was minimal.Fabienne D. Uehlinger, Spencer J. Greenwood, J. Trenton McClure, Gary Conboy, Ryan O’Handley, Herman W. Barkem

Rendell, Chem. Phys. Lett. 177. 491 (1991)Author Institution: Institute for Astrophysics and Planetary Sciences, Ibaraki University; Institute for Astrophysics and Planetary Sciences, Nobeyama Radio ObservatoryThe transition dipole moments for the fundamental bands of HNC were obtained from analyses of Herman-Wallis effect on the absorption intensities. All the fundamental bands were measured using a Fourier transform infrared spectrometer (Bruker IFS 120HR) at Nobeyama Radio Observatory. A glow discharge in a mixture of ( mTorr), , and Ar( mTorr) was used for production of HNC The spectra were recorded with resolution of and the absorption path length was 24 m. The experimentally determined first order Herman-Wallis coefficients for the and bands, combined with the relative value of the transition dipole moments for the and bands derived from the relative intensity measurements, yielded the following values for the transition dipole moments (in Debye), using the expressions for Herman-Wallis coefficients given by . These values are considerably larger than the corresponding values for and are in reasonable agreement with {ab initio}
Mass capture and anesthesia of Australian bridled nailtail wallabies (Onychogalea fraenata) with the use of medetomidine and ketamine
No full textWe anesthetized 301 bridled nailtail wallabies (Onychogalea fraenata), captured within Scotia Sanctuary, New South Wales, Australia over four nights in October 2009 to perform health assessments before their release into a predator-proof exclosure. We tested two anesthetic dose-rate combinations, protocol 1 (0.08 mg/kg medetomidine-4.5 mg/kg ketamine), and protocol 2 (0.1 mg/kg medetomidine-5 mg/kg ketamine), each given intramuscularly. Median time from injection to recumbency for protocol 1 was 10 min (1-27 min) and for protocol 2 was 12 min (2-28) (P = 0.12). Five animals died during the induction with protocol 2; none died with protocol 1 (P = 0.06). Physiologic parameters were recorded during recumbency, with no significant abnormalities with protocol 1. Protocol 1 was an effective, efficient regime to anesthetize large numbers of bridled nailtail wallabies under field conditions.Wayne S. J. Boardman, Charles G.

Of the first and second row diatomic hydrides, ab initio calculations predict SH to exhibit the largest H.W. effect. Indeed, our spectra confirm a very large effect, and we present here an attempt at a quantitative analysis of the Herman-Wallis intensity perturbation in SH

Reading acts of narrative appropriation: four instances of fraudulent memoir
No full textPhDThis thesis examines acts of narrative appropriation, the telling of purportedly‘authentic’ life stories by those for whom the stories are not theirs to tell. This
misuse or subversion of genre - the discipline of historical writing and the category
of autobiography - becomes a means for cultural, social and political dissimulation,
and the analysis focuses both on the act: the event, trespass, or ‘theft’ of another’s
life story, and on the cultural meaning that this event reveals. These narrative acts
are approached theoretically through discussions of what it means to be an author, a
reader, and through the consideration of literary and social genre, category and form.
In exploring identities at particular risk of appropriation, this thesis shows how
fraudulent appropriated narratives affect our reading of the world, and in turn
influence our perception of already marginalized social groups. My primary
examples include prostitution ‘narratives’, Native North American ‘memoir,’ and
fraudulent Holocaust survivor ‘testimony,’ with each text providing decoded
evidence of ‘genre-bending’ exhibiting a social and political intent. These works
seek to be read as authentic personal narratives, as autobiography, and that is how
they have been presented to the reader. However, they are imposters – fictional tales
desiring the elevated status of historical authenticity and willing to bend the rules
and contracts of genre to achieve their end. Here the appearance of authenticity is
achieved through the use of cultural and social ‘myth,’ or perceptions of cultural
identity, and as such its fraudulent construction is first and foremost a social act,
with a social and economic motivation. As this thesis concludes, these texts are
most successful when their own political and social ideologies echo and confirm that
of the readership; when their subjects, the fraudulent ‘I’ at the center of the text is
also a performative elaboration of cultural belief
