Joanna E. Wood short stories, 1898-1900

Joanna Ellen Wood (1867-1927) was an acclaimed Canadian author who wrote several novels and short stories. Wood was born in Scotland, but emigrated to Canada with her family in 1869. In 1874 her father purchased a farm overlooking the Niagara River at Queenston. It is believed she was supported by her brother William, who encouraged her writing. She was based in New York City from 1887-1901, using William’s business address there to receive correspondence while she traveled or spent time in Queenston. Around 1906, Wood moved with her mother to Niagara-on-the-Lake, where she joined the Niagara Historical Society. By 1914, she was living in Buffalo, but later spent time at her sisters’ homes. It was at her sister’s home in Detroit where she suffered a stroke and died in 1927. Wood’s literary career was short-lived. She published her first novel, The Untempered Wind , in 1894, and a second novel, Judith Moore …, in 1898. Both novels received critical acclaim, and a third novel, Farden Ha', followed in 1902. Unfortunately the majority of Wood’s numerous and award-winning writings cannot be found. Her career peaked in 1901, when she was the highest paid Canadian fiction writer. For unknown reasons, her career abruptly ceased in 1902, with no further publications or mention made of her in the Canadian Magazine.

Évaluation de l’effet de faux souvenirs en vieillissement normal : validation de scores composites des fonctions temporale médiane et frontale et contribution aux hypothèses théoriques

L’avancement en âge est associé à plusieurs modifications cognitives, dont un déclin des capacités à mémoriser et/ou à rappeler les événements vécus personnellement. Il amène parallèlement une augmentation des faux souvenirs, c.-à-d. le rappel d’événements qui ne se sont pas réellement déroulés. Les faux souvenirs peuvent avoir d’importantes répercussions dans la vie quotidienne des personnes âgées et il importe donc de mieux comprendre ce phénomène en vieillissement normal. Des études ont démontré l’importance de la fonction des lobes temporaux médians (FTM)/mémoire et de la fonction des lobes frontaux (FF)/fonctions exécutives dans l’effet de faux souvenirs. Ainsi, la première étude de la thèse visait à valider en français une version adaptée d’une méthode proposée par Glisky, Polster, & Routhieaux (1995), permettant de mesurer ces fonctions cognitives (Chapitre 2). L’analyse factorielle de cette étude démontre que les scores neuropsychologiques associés à la mémoire se regroupent en un facteur, le facteur FTM/mémoire, alors que ceux associés aux fonctions exécutives se regroupent en un deuxième facteur, le facteur FF/fonctions exécutives. Des analyses « bootstrap » effectuées avec 1 000 ré-échantillons démontrent la stabilité des résultats pour la majorité des scores. La deuxième étude de cette thèse visait à éclairer les mécanismes cognitifs (FTM/mémoire et FF/fonctions exécutives) ainsi que théoriques de l’effet de faux souvenirs accru en vieillissement normal (Chapitre 3). La Théorie des Traces Floues (TTF; Brainerd & Reyna, 1990) propose des explications de l’effet de faux souvenirs pour lesquelles la FTM/mémoire semble davantage importante, alors que celles proposées par la Théorie de l’Activation et du Monitorage (TAM; Roediger, Balota, & Watson, 2001) sont davantage reliées à la FF/fonctions exécutives. Les tests neuropsychologiques mesurant la FTM/mémoire ainsi que ceux mesurant la FF/fonctions exécutives ont été administrés à 52 participants âgés (moyenne de 67,81 ans). Basé sur l’étude de validation précédente, un score composite de la FTM/mémoire et un score composite de la FF/fonctions exécutives ont été calculés pour chaque participant. Ces derniers ont d’abord été séparés en deux sous-groupes, un premier au score FTM/mémoire élevé (n = 29, âge moyen de 67,45 ans) et un deuxième au score FTM/mémoire faible (n = 23, âge moyen de 68,26 ans) en s’assurant de contrôler statistiquement plusieurs variables, dont le score de la FF/fonctions exécutives. Enfin, ces participants ont été séparés en deux sous-groupes, un premier au score FF/fonctions exécutives élevé (n = 26, âge moyen 68,08 ans) et un deuxième au score FF/fonctions exécutives faible (n = 25, âge moyen de 67,36 ans), en contrôlant les variables confondantes, dont le score de la FTM/mémoire. Les proportions de vraie et de fausse mémoire (cibles et leurres associatifs) ont été mesurées à l’aide d’un paradigme Deese-Roediger et McDermott (DRM; Deese, 1959; Roediger & McDermott, 1995), avec rappel et reconnaissance jumelée à une procédure « Je me souviens / Je sais » (Tulving, 1985) chez les 52 participants âgés ainsi que chez 22 jeunes (âge moyen de 24,59 ans), apparié pour les années de scolarité. D’abord, afin de tester l’hypothèse de la TTF (Brainerd & Reyna, 1990), ces proportions ont été comparées entre les jeunes adultes et les deux sous-groupes de personnes âgées catégorisées selon le score de la FTM/mémoire. Ensuite, afin de tester l’hypothèse de la TAM (Roediger et al., 2001), ces proportions ont été comparées entre les jeunes adultes et les deux sous-groupes de personnes âgées catégorisées selon le score de la FF/fonctions exécutives. Il s’agit de la première étude qui compare directement ces hypothèses à travers de nombreuses mesures de vraie et de fausse mémoire. Les résultats démontrent que seule la FTM/mémoire modulait l’effet d’âge en vraie mémoire, et de manière quelque peu indirecte, en fausse mémoire et dans la relation entre la vraie et la fausse remémoration. Ensuite, les résultats démontrent que seule la FF/fonctions exécutives jouerait un rôle dans la fausse reconnaissance des leurres associatifs. Par ailleurs, en des effets d’âge sont présents en faux rappel et fausse remémorations de leurres associatifs, entre les jeunes adultes et les personnes âgées au fonctionnement cognitif élevé, peu importe la fonction cognitive étudiée. Ces résultats suggèrent que des facteurs autres que la FTM/mémoire et la FF/fonctions exécutives doivent être identifiés afin d’expliquer la vulnérabilité des personnes âgées aux faux souvenirs. Les résultats de cette thèse sont discutés à la lumière des hypothèses théoriques et cognitives en faux souvenirs (Chapitre 4).

Conducting Polyaniline Composites as Microwave Absorbers

Conducting polymers are excellent microwave absorbers and they show technological advantage when compared with inorganic electromagnetic absorbing materials, being light weight , easily processable, and the ability of changing the electromagnetic properties with nature and amount of dopants, synthesis conditions, etc. In this paper we report the synthesis, dielectric properties, and expected application of conducting composites based on polyaniline (PAN). Cyclohexanone soluble conducting PAN composites of microwave conductivity 12.5 S/m was synthesized by the in situ polymerization of aniline in the presence of emulsion grade polyvinyl chloride. The dielectric properties of the composites, especially the dielectric loss, conductivity, dielectric heating coefficient , absorption coefficient, and penetration depth, were studied using a HP8510 vector network analyzer. The microwave absorption of the composites were studied at different frequency bands i.e, S, C, and X bands (2-12 GHz). The absorption coefficient was found to be higher than 200 m -' and it can be used for making microwave absorbers in space applications .

Dielectric Behavior of Natural Rubber Composites in Microwave Fields

In this article, we report the preparation of conducting natural rubber (NR) with polyaniline (Pani). NR was made into a conductive material by the compounding of NR with Pani in powder form. NR latex was made into a conductive material by the in situ polymerization of aniline in the presence of NR latex. Different compositions of Pani- NR semi-interpenetrating networks were prepared, and the dielectric properties of all of the samples were determined in microwave frequencies. The cavity perturbation techpique was used for this study. A HP8510 vector network analyzer with a rectangular cavity resonator was used for this study. S bands 2-4 GHz in frequency were used. Thermal studies were also carried out with thermogravimetric analysis and differential scanning calorimetry.

Effect of Different Forms of Poly o-Toluidine /Poly Vinyl Chloride Composites on Dielectric Propertiesin the Microwave Field

In this paper we report the preparation and dielectric properties of poly o-toluidine:poly vinyl chloride composites in pellet and film forms. The composites were prepared using ammonium persulfate initiator and HCl dopant. The characterization is done by TGA and DSC. The dielectric properties including dielectric loss, conductivity, dielectric constant, dielectric heating coefficient, absorption coefficient, and penetration depth were studied in the microwave field. An HP8510 vector network analyzer with rectangular cavity resonator was used for the study. Sbands (2-4 GHz), C band (5-8 GHz), and X band (8-12 GHz) frequencies were used in the microwave field. Comparisons between the pellet and film forms of composites were also included. The result shows that the dielectric properties in the microwave field are dependent on the frequency and on the method of preparation.

Swelling behaviour of isora/natural rubber composites in oils used in automobiles

Natural rubber/isora fibre composites were cured at various temperatures. The solvent swelling characteristics of natural rubber composites containing both untreated and alkali treated fibres were investigated in aromatic and aliphatic solvents like toluene, and n-hexane. The diffusion experiments were conducted by the sorption gravimetric method. The restrictions on elastomer swelling exerted by isora fibre as well as the anisotropy of swelling of the composite have been confirmed by this study. Composite cured at 100°C shows the lowest percentage swelling. The uptake of aromatic solvent is higher than that of aliphatic solvent for the composites cured at all temperatures. The effect of fibre loading on the swelling behaviour of the composite was also investigated in oils like petrol, diesel, lubricating oil etc. The % swelling index and swelling coefficient of the composite were found to decrease with increase in fibre loading. This is due to the increased hindrance exerted by the fibres at higher fibre loadings and also due to the good fibre-rubber interactions. Maximum uptake of solvent was observed with petrol followed by diesel and then lubricating oil. The presence of bonding agent in the composites restrict the swelling considerably due to the strong interfacial adhesion. At a fixed fibre loading, the alkali treated fibre composite showed lower percentage swelling compared to the untreated one.

Mechanical Properties of Short-Isora-Fiber-Reinforced Natural Rubber Composites: Effects of Fiber Length, Orientation, and Loading; Alkali Treatment;and Bonding Agent

A series of short-isora-fiber-reinforced natural rubber composites were prepared by the incorporation of fibers of different lengths (6, 10, and 14 mm) at 15 phr loading and at different concentrations (10, 20, 30, and 40 phr) with a 10 mm fiber length. Mixes were also prepared with 10 mm long fibers treated with a 5% NaOH solution. The vulcanization parameters, processability, and stress-strain properties of these composites were analyzed. Properties such as tensile strength, tear strength, and tensile modulus were found to be at maximum for composites containing longitudinally oriented fibers 10 mm in length. Mixes containing fiber loadings of 30 phr with bonding agent (resorcinol-formaldehyde [RF] resin) showed mechanical properties superior to all other composites. Scanning electron microscopy (SEM) studies were carried out to investigate the fiber surface morphology, fiber pullout, and fiber-rubber interface. SEM studies showed that the bonding between the fiber and rubber was improved with treated fibers and with the use of bonding agent.

Rubber Solution Adhesives for Wood-to-Wood Bonding

Rubber solutions were prepared and used for bonding wood pieces. The effect of the variation of chlorinated natural rubber (CNR) and phenolformaldehyde (PF) resin in the adhesive solutions on lap shear strength was determined. Natural rubber and neoprene-based adhesive solutions were compared for their lap shear strength. The storage stability of the adhesive prepared was determined. The change in lap shear strength before and after being placed in cold water, hot water, acid, and alkali was tested. The bonding character of these adhesives was compared with different commercially available solution adhesives. The room-temperature aging resistance of wood joints was also determined. In all the studies, the adhesive prepared in the laboratory was found to be superior compared to the commercial adhesives.
