Characterization andmetals fractionation of street dust samples fromTehran, Iran
No full textFifty street dust samples were collected from Southern and Eastern parts of Tehran, the capital of Iran. Samples were collected during summer under dry and stable weather conditions. Total concentrations of copper (Cu), cadmium (Cd), lead (Pb), chromium (Cr), nickel (Ni), zinc (Zn), iron (Fe), manganese (Mn) and lithium (Li) were determined. Ten samples were then selected for characterization, metals fractionation and single stage extraction studies. X-ray diffraction (XRD) and X-ray fluorescence (XRF) were utilized to study the crystalline forms of metals and chemical compositions. In addition, sequential and single extraction
procedures were used to determine the concentrations of six heavy metals (i.e. Cu, Cd, Pb, Cr, Ni and Zn), and also the mobility and bioavailability of elements. The risk assessment code (RAC) and IPOLLwere employed for the risk assessment and pollution intensity of metals, respectively. Results showed that the single extraction procedure could be used to estimate the total concentrations of most metals as an appropriate alternative for total digestion. The mobility and potential availability of metals in Tehran street dust followed the order of Cd > Zn > Pb > Cu > Ni > Cr. The risk assessment code results showed high risk for Pb, Cd and Zn and low medium risk for Ni, Cr and Cu, and correlated positively with IPOLL result
Pioneer Highway; new paintings by Tim Croucher
Get PDFThe stretch from the Square, down Pioneer Highway, past Jackeytown Road, Karere Lagoon and out to Foxton, measured the centre of my early childhood. As I grew, my area expanded to include Shannon, Feilding, the Whirokino Trestle and river bank, the Pohongina Valley, and up to the Desert Road and Taupo. And, of course, to Wellington.
Between the late 1800s and 1940s, flax milling was a big industry in much of the area around Tiakitahuna. A substantial flax mill was located at the Opiki Bridge. We’d often drive across its creaking boards… it’s still a fascinating place to visit because of the spectre of its towers and the ragged wires that invite climbing.
Flax growing and milling altered the swampy landscape, enflamed tensions between Māori and colonials, encouraged the formation of trade unions, and polluted the Manawatū River.
Visiting Manawatū and Rangitikei now, I like that it’s all shifted and changed to accommodate current needs and amusements. The reminders are still there, but there are carparks, boat ramps, racetracks and ‘light no fires’ signs.
This exhibition comprises a suite of paintings that mingle historical, pastoral, and imaginary situations; it is a tender and playful reflection on a set of unglamorous yet peculiar locations and the identities that link to them
Supervision of student photographic work for the second exhibition of - A walk in the park - poster exhibition - Hamilton Central Library, May-June 2015.
No full textThis exhibition is the second showing of the initial ‘A walk in the park’ exhibition. This new work poster exhibition is a collected of selected photographs presented as posters that support local stories. It is a multimedia project that showcases some of Hamilton's numerous open spaces in words and images. It is a collaboration between Wintec School of Media Arts and the Hamilton City Council

Glicentin-related pancreatic polypeptide inhibits glucose-stimulated insulin secretion from the isolated pancreas of adult male rats.
No full textSeveral peptides derived from the glucagon gene Gcg, for example glucagon and glucagon-like peptide 1 (GLP-1), act as major regulators of fuel metabolism. GLP-1 is an incretin which has given rise to two new classes of anti-diabetic agents, the GLP-1 agonists and the DPP4 inhibitors. Glucagon is another potent Gcg-derived glucoregulatory hormone whose main regulatory role is to increase glucose output from the liver. Peptides derived from Gcg are thus of major interest in the regulation of intermediary metabolism, the pathogenesis of diseases such as type-2 diabetes and obesity, and their therapeutic management. Glicentin-related pancreatic polypeptide (GRPP) is a further, 30 amino-acid Gcg-derived peptide identified in human, mouse, rat and pig. A closely-related peptide, GRPP-like peptide (GRPP-LP) has also been identified in rat islets. The potential glucoregulatory functions of these peptides are largely unknown. We synthesized rat GRPP (rGRPP) and rat GRPP-LP (rGRPP-LP) and determined their actions in the liver and pancreas of adult male rats by employing isolated-perfused organ preparations. Rat GRPP and rGRPP-LP did not affect glucose output from the liver but both elicited potent inhibition of glucose-stimulated insulin secretion from the rat pancreas. This action is unlikely to be mediated by glucagon or GLP-1 receptors as rGRPP and rGRPP-LP did not stimulate cyclic adenosine monophosphate (cAMP) production from the glucagon or GLP-1 receptors, nor did they antagonize glucagon- or GLP-1-stimulated cAMP-production at either receptor. GRPP and GRPP-LP may be novel regulators of insulin secretion, acting through an as-yet undefined receptor
Positioning the self reflexively in qualitative research interviews
No full textThis presentation critically examines my experience of interviewing registered nurses who related stories about caring for their own dying family members at home and in hospital. In this research I came to understand that interviewing participants who had experienced loss similar to my own, created moments when I empathised with them as colleagues and women. In the interviews I found myself engaging with them in ways that were protective as I became focused on their vulnerability. As a nurse, I also brought a professional gaze that was concerned with the normative requirements of conduct for registered health professionals, albeit it representations of conduct within personal relationships. When participants gave detailed accounts of struggles with medicine management and requests for help to die, I realised that my responses were leading them away from sensitive topics

Get PDFNew Zealand Taxation 2015 Principles, Cases and Questions
No full textNew Zealand Taxation has been used in all New Zealand Universities and most Technical Institutes throughout New Zealand since 2004. Originally written by Clinton Alley, Andrew Maples, and John Veal, this book now has 27 chapters covering all aspects of taxation in New Zealand. It is designed to elucidate the most complex and problematic law written in New Zealand, and to build a framework on which the different taxation concepts can be understood. Rather than simply restating the law, it explains taxation policies and procedures and critically evaluates taxation regimes as well as providing cases, review questions, references and further reading lists. It is a comprehensive, research based book, written by academics and professionals with life time experiences of taxation
