Letter - Ian Green to Sean O'Sullivan, July 1977

A correspondence between Ian Green and Sean O'Sullivan from July 1977. The first letter is from 4 July 1977 from Sean O'Sullivan, titled "The Nation's Business". He requests a discussion about "Caucus morale". O'Sullivan requests that Joe Clark individually acknowledge members of the party and say "a few words about how proud he is of the men and women who form the P.C. Caucus, and how well they represent the country--moreover, how well they are prepared to help form the next Government." A response from Ian Green (Legislative Assistant) is positive and he forwards the memo to Jodi White, Director of Communications.

An investigation of ethylene inhibition of growth in etiolated Avena sativa coleoptiles /

Growth rates of etiolated Avena sativa coleoptiles in pH 7.0 buffered medium are stimulated in a synergistic manner by IAA and 320 ~l/l carbon dioxide. The suggestion that carbon dioxide stimulated growth involves dark fixation is supported by the ability of 1 mM malate to replace carbon dioxide, with neither factor able to stimulate growth in the presence of the other (Bown, Dymock and Aung, 1974). The regulation of Avena coleoptile growth by ethylene has been investigated in the light of this data and the well documented antagonism between carbon dioxide and ethylene in the regulation of developmental processes. The influence of various permutations of ethylene, IAA, carbon dioxide and malate on the rates of growth, l4c-bicarbonate incorporation, l4C-bicarbonate fixation, and malate decarboxylation have been investigated. In the presence of 320 ~l/l carbon dioxide, 10.8 ~l/l ethylene inhibited growth both in the absence and presence of 20 ~M IAA with inhibition times, of 8-10 and 12-13 minutes respectively. In contrast ethylene inhibition of growth was not significant in the absence of growth stimulation by CO2 or 1 mM malate, and the normal growth increases in response to CO2 and malate were blocked by the simultaneous application of ethylene. The rates of incorporation and dark fixation of l4C-bicerbonate were not measurably. influenced by ethylene, IAA or malate, either prior to or during the changes in growth ,ates induced by these agents. The data does not support the hypothesis that ethylene inhibition of growth results from an inhibition of dark fixation, but suggests that ethylene may inhibit a process which is subsequent to fixation.

Hydraulic and fluvial geomorphological models for a bedrock channel reach of the Twenty Mile Creek /

Bedrock channels have been considered challenging geomorphic settings for the application of numerical models. Bedrock fluvial systems exhibit boundaries that are typically less mobile than alluvial systems, yet they are still dynamic systems with a high degree of spatial and temporal variability. To understand the variability of fluvial systems, numerical models have been developed to quantify flow magnitudes and patterns as the driving force for geomorphic change. Two types of numerical model were assessed for their efficacy in examining the bedrock channel system consisting of a high gradient portion of the Twenty Mile Creek in the Niagara Region of Ontario, Canada. A one-dimensional (1-D) flow model that utilizes energy equations, HEC RAS, was used to determine velocity distributions through the study reach for the mean annual flood (MAF), the 100-year return flood and the 1,000-year return flood. A two-dimensional (2-D) flow model that makes use of Navier-Stokes equations, RMA2, was created with the same objectives. The 2-D modeling effort was not successful due to the spatial complexity of the system (high slope and high variance). The successful 1 -D model runs were further extended using very high resolution geospatial interpolations inherent to the HEC RAS extension, HEC geoRAS. The modeled velocity data then formed the basis for the creation of a geomorphological analysis that focused upon large particles (boulders) and the forces needed to mobilize them. Several existing boulders were examined by collecting detailed measurements to derive three-dimensional physical models for the application of fluid and solid mechanics to predict movement in the study reach. An imaginary unit cuboid (1 metre by 1 metre by 1 metre) boulder was also envisioned to determine the general propensity for the movement of such a boulder through the bedrock system. The efforts and findings of this study provide a standardized means for the assessment of large particle movement in a bedrock fluvial system. Further efforts may expand upon this standardization by modeling differing boulder configurations (platy boulders, etc.) at a high level of resolution.

Force potentiation in the MDX mouse

Large forces are the primary mechanism of injury in muscular dystrophy, and muscular dystrophy is especially damaging to type IIB muscle fibers. It was hypothesized that post-tetanic potentiation (PTP) would be down-regulated to prevent damage in Xlinked muscular dystrophy (mdx) mice since PTP increases force and PTP effects are greatest in IIB fibers. PTP experiments were performed on the extensor digitorum longus (EDL) of 50 day old mdx (YM) and C57BL/10 (YC) mice and 10 month old mdx (OM) and C57B1710 (OC) mice. Twitch and tetanic forces were lower in mdx than controls and lower in younger than older mice. Contrary to the hypothesis, PTP was higher in both mdx groups compared to controls. OM potentiated more than any other condition (OM: 29.8%, OC: 23.2%, YM: 21.9%, YC: 17.2%). In accordance with literature PTP increased in the older groups. To explain PTP changes, fiber typing and Western blots for myosin light chain kinase (MLCK) were performed. YM and YC had similar fiber type profiles (2% I, 58% IIX/D and 40% IIB). In accordance with literature but contrary to expected conditions for elevated PTP, OM had a slower fiber type profile (1.7% I, 69% IIX/D and 29% IIB) than OC (0.4% I, 61% IIX/D and 38% IIB). No differences were found in MLCK expression. It seems that PTP is up-regulated to maintain muscle function rather than being down-regulated to prevent muscle damage. Ca""^ transient and myosin phosphorylation measurements would be beneficial in explaining increased PTP seen in this study.

A comparison of life satisfaction, job satisfaction, and happiness using demographic variables

This study examined the interrelationships among life satisfaction, job satisfaction, and happiness and the selected demographic variables of income, age, marital status, education, sex, job tenure, job title, type of school, and location of employment. Survey data were collected from 1,993 elementary, high school, and community college teachers in the southern Ontario area, representing ten public school boards, three Roman Catholic school boards and three community colleges. Several theories were utilized in developing thirteen hypotheses and eleven experimental hypotheses. A thorough review of the literature (to January, 1980) was undertaken and major conclusions noted. Hoppock's (1935) Job Satisfaction Measure, Gurin, Veroff, and Feld's (1960) Happiness Scale, and Converse and Robinson's (1965) Life Satisfaction Scale were used as the instrument. Chi-square analysis was employed as the statistical method. Indicative of the findings: the level of education taught was significantly related to all three organizational variables, sex was unrelated to life satisfaction though positively related to job satisfaction, and income was found not to be related to either happiness or life satisfaction. A minority of findings were contrary to hypothesized relationships. Specifically, age was found to be unrelated to any of the three organizational variables, and educational achievement was not significantly related to happiness. A model was developed to illustrate the interrelationships of the organizational and demographic variables. This model was designed specifically to reflect teacher attitudes, though it may have reasonable application for other relatively homogeneous groups of employees such as nurses, engineers, or social workers.

An investigation into the oxidation of organic sulphides, organic selenides and simple hydrocarbons by Mortierella isabellina NRRL 1757

The work presented in this thesis is divided into three separate sections 4!> Each' 'section is involved wi th a different problem, however all three are involved with a microbial oxidation of a substrate~ A series of 'aryl substituted phenyl a.nd be,nzyl methyl sulphides were oxidized to the corre~pondi~g sulphoxides by 'Mo:rtierellai's'a'b'e'llina NRR.L17'S7 @ For this enzymic Qxidation, based on 180 labeled experiments, the oxygen atom is derived fr'orn the atmosphere and not from water. By way of an u~.traviolet analysis, the rates of oxidation, in terms of sulphox~ de appearance, were obtained and correlated with the Hatnmett p s~grna constants for the phenyl methyl sulphide series. A value of -0.67 was obtained and, is interpreted in terms of a mechanism of oxidation that involves an electrophilic attack on the sulphide sulphur by an enzymic ironoxygen activated complex and the conversion of the resulti!lg sulphur cation to sulphoxide. A series of alkyl phenyl selen~des have been incubated with the fu~gi, Aspergillus niger ATCC9l42, Aspergillus fO'etidus NRRL 337, MIIJisabellina NF.RLl757 and'He'lminth'osparium sp'ecies NRRL 4671 @l These fu?gi have been reported to be capable of carrying out the efficient oxidation of sulphide to sulphoxide, but in no case was there any evidence to supp'ort the occurrence of a microbialox,idation.
