La mémoire collective et le paysage urbain tatoués des vestiges du passé: La corderie du quartier St-sauveur

Cette recherche vise, dans un premier temps, à colliger les informations existantes sur l’histoire de la corderie du quartier Saint-Sauveur qui passa au feu en 1866 dans un seul document tout en le bonifiant des nouveaux éléments trouvés. Puis, dans un deuxième temps, élaborer diverses activités artistiques thématiques inspirées de son histoire afin de réaliser une œuvre collective grâce à la participation d’aînés fréquentant le Centre de jour du Centre d’hébergement Notre-Dame-de-Lourdes, centre directement situé sur le site où la corderie avait été construite. Enfin, la recherche vise aussi à découvrir quelles sont les retombées pour ces aînés impliqués dans le processus de création. La recherche s’inscrit dans une perspective herméneutique puisque la question de signification et de sens en est le cœur. Que ce soit selon l’approche de Heidegger, de Gadamer, de Dilthey, de Ricœur ou celle de Grondin, chacune des avenues que ces auteurs proposent sont des pistes de compréhension. Les notions de textile, de trace, de mémoire et d’histoire contribuent aussi à éclairer et à analyser les réponses au questionnement qui sous-tend cette recherche. Les résultats obtenus permettent d’en connaître davantage sur le développement de la partie sud-est du quartier Saint-Sauveur au XIXe siècle, développement étroitement relié à la construction de navires à voiles, vaste industrie qui participa à l’essor de la ville de Québec à la même époque. Les résultats permettent aussi de comprendre ce que les thèmes inspirés de l’histoire de la corderie représentent pour les aînés participant à la création et aident également à découvrir ce que les participants ont pu retirer d’une telle expérience et ce, pour l’ensemble du processus. Mots clés : Corderie – quartier Saint-Sauveur – herméneutique – aîné – œuvre collective – textile.

Les stratégies d’exploitation de l’archipel côtier du Labrador : une étude de cas du 18e siècle au site d’Ikkeghasarsuk

La fin du 18e siècle était une période dynamique au Labrador. À cette époque, le phénomène climatique nommé le Petit Âge glaciaire affectait grandement l’étendue de la banquise côtière. L’arrivée des missionnaires et des objets européens enclencha une réorganisation des rôles sociaux chez les Inuits. L’établissement hivernal d’Ikkeghasarsuk, connu sous le code Borden HdCg-23 et le nom de site officiel Koliktalik-6, est composé principalement de deux maisons semi-souterraines construites avant 1776 sur un site dorsétien. La présente étude explore les stratégies d’occupation du territoire par l’analyse des restes fauniques de ces deux maisons. Les espèces de phoques chassées et leurs niches écologiques indiquent que les occupants du site exploitaient surtout les phoques présents dans les eaux libres de glace à l’automne, les phoques annelés au sina l’hiver et les phoques annelés sur la banquise côtière au printemps. Le site d’Ikkeghasarsuk, placé sur une île dénudée et balayée par le vent, aurait permis d’avoir un accès privilégié aux ressources marines diverses, peu importe les conditions climatiques.

La poésie à l’école secondaire québécoise (1963-2016) - Une histoire à travers les textes

Afin de comprendre et d’expliquer le malaise actuel vis-à-vis de l’enseignement de la poésie au secondaire, la thèse remonte à la publication du Rapport Parent (1963-1966), document fondateur de l’école québécoise moderne, et à la création du ministère de l’Éducation du Québec (1964) pour suivre, à travers les documents, l’histoire de l’enseignement de la poésie au secondaire au cours des 50 dernières années. Cette période se divise en trois grandes étapes : une révolution en éducation marquée par la publication du Rapport Parent et de deux programmes; le retour aux sources amorcé par L’école québécoise qui verra deux programmes et deux séries de manuels scolaires; la réforme articulée autour de L’école, tout un programme dont les programmes et les manuels sont actuellement en vigueur. C’est à travers ces trois types de documents (documents d’orientation, programmes d’enseignement et manuels scolaires) que je retracerai le parcours de l’enseignement de la poésie à l’école secondaire avec comme toile de fond les grands courants qui ont marqué l’éducation et l’enseignement du français au Québec depuis les années 1960. L’enseignement de la poésie ne peut se détacher du contexte dans lequel il se fait. Ce contexte comprend diverses facettes qui lui sont internes et d’autres qui lui sont externes. Les facettes externes dans ce travail sont la vision de la culture et de l’enseignement ainsi que la place faite à la littérature et à la poésie. L’idée de culture a beaucoup évolué depuis 50 ans. Le Rapport Parent abandonne la vision traditionnelle de la culture au profit d’une vision plus large qui englobe l’ensemble des activités humaines. Nuancée et actualisée, cette vision large de la culture restera la référence. La littérature qui détenait une place importante dans la culture traditionnelle perd ainsi de l’influence. Sa place et son importance, malgré les discours qui la valorisent, vont diminuer jusqu’à ne devenir qu’un adjuvant à l’enseignement de la technique de la langue et des types de textes. L’évolution de l’enseignement transformera la classe traditionnelle bien ordonnée sous l’autorité du maitre en lieu qui doit permettre à l’élève de construire ses connaissances. Les éléments reliés directement à l’enseignement de la poésie comprennent les programmes, les manuels, l’enseignement de la lecture et de l’écriture et le travail du professeur et de l’élève. Les programmes subiront d’importantes modifications. Le programme-cadre de 1969 marque la fin des programmes à visées littéraires. Le seul vrai but des programmes depuis, c’est de parfaire l’apprentissage technique de la langue. Le programme de 1980 marque l’abandon des genres littéraires comme base de l’enseignement des textes au profit de la notion de discours. Comme le discours poétique n’y apparait pas, la poésie peine à se trouver une place. Les programmes de 1995 et de la réforme optent pour les types de textes plutôt que les discours, mais la poésie n’entre pas dans cette typologie. La place de la poésie en lecture et en écriture est variable selon les époques. Sur un même pied que les autres types de textes dans le programme-cadre, elle apparait seulement en lecture dans le programme de 1980. Les programmes subséquents lui redonneront une place en écriture. Depuis 1980, elle reste un genre marginal qui souvent ne sert qu’à illustrer des notions utiles aux discours ou types de textes utilisés par le programme. La relation professeur/élève s’est considérablement modifiée au cours de cette période. De maitre, le professeur est devenu guide et médiateur. L’élève évolue en sens inverse : de passif récepteur de la connaissance, il devient responsable de construire ses connaissances. Le professeur, compte tenu du peu de place qu’occupe la poésie dans les programmes et du fait qu’elle ne fait pas partie de la typologie des textes adoptée par ceux-ci, ne peut compter que sur ses connaissances pour en assurer un enseignement valable. Les manuels accompagnent les programmes sauf pour le programme-cadre. Depuis 1980, les manuels de français ont une visée autoéducative parce qu’ils s’adressent directement à l’étudiant. Ils se présentent comme des préparations de cours que l’élève n’a qu’à suivre pour acquérir les connaissances au programme. La place de la poésie en lecture et en écriture y est variable selon les époques et les manuels.

Xanten-Vetera - Analyse et caractérisation du processus de colonisation et de romanisation d’une région frontalière en Germanie inférieure

Ce mémoire analyse le processus de romanisation et de colonisation de Xanten-Vetera, une région frontalière de l’Empire romain située en basse Rhénanie dans la province romaine de Germania inferior. À l’intérieur d’un cadre temporel inclus entre les conquêtes de Jules César et le milieu du second siècle apr. J.-C., l’étude cherche à comprendre et à restituer la présence militaire ainsi que le développement des peuplades civiles sur place, du fait des transferts de population et de l’immigration gallo-romaine. Le processus de romanisation est analysé en tenant compte des réalités ethnographiques, sociales et culturelles et selon les théories les plus actuelles de la recherche moderne sur ce sujet. Comme il s’agit d’une agglomération située sur une voie fluviale en périphérie de l’Empire, le concept de « frontière » y est évalué afin d’estimer si Xanten-Vetera constituait une zone de convergence ou de divergence par rapport à l’espace rhénan. Dans un deuxième temps, cette recherche analyse le contexte militaire et social durant lequel l’empereur Trajan prit la décision d’octroyer le statut de colonie à ce territoire qui devint la Colonia Ulpia Traiana. Cette démarche qui se veut régionale souligne la nature particulière de l’histoire de Xanten-Vetera sous le Haut Empire ; les migrations et les tragédies à l’intérieur de cet espace géographique ont façonné un endroit au destin unique en Germanie et dans l’Empire romain. Enfin, ce travail fournit un exemple pertinent de l’évolution des motivations qui ont guidé les politiques coloniales sous les Julio-Claudiens, les Flaviens et les Antonins et suggère l’essor des groupes de pression non militaires dans ce contexte.

Validação e estimativa da incerteza de método para análise de licopeno e 46;-caroteno em polpa de tomate por cromatografia líquida de alta eficiência

A method to quantify lycopene and 46;-carotene in freeze dried tomato pulp by high performance liquid chromatography (HLPC) was validated according to the criteria of selectivity, sensitivity, precision and accuracy, and uncertainty estimation of measurement was determined with data obtained in the validation. The validated method presented is selective in terms of analysis, and it had a good precision and accuracy. Detection limit for lycopene and 46;-carotene was 4.2 and 0.23 mg 100 g-1, respectively. The estimation of expanded uncertainty (K = 2) for lycopene was 104 ± 21 mg 100 g-1 and for 46;-carotene was 6.4 ± 1.5 mg 100 g-1.

Áreas de vulnerabilidade para co-infecção HIV-aids/TB em Ribeirão Preto, SP

OBJETIVO: Identificar áreas de vulnerabilidade para os casos novos de co-infecção HIV/tuberculose (TB). MÉTODOS: Estudo descritivo ecológico realizado por meio do georreferenciamento dos casos novos de HIV/TB notificados em Ribeirão Preto, SP, em 2006. Os dados foram obtidos do sistema de informação estadual paulista de notificação de TB. Os casos novos de co-infecção HIV/TB foram analisados conforme características sociodemográficas e clínicas e, posteriormente, georreferenciados na base cartográfica do município segundo endereço residencial. Os setores do município foram categorizados em três níveis socioeconômicos: inferior, intermediário e superior, com base na análise de componentes principais das variáveis do censo demográfico de 2000 (renda, instrução e percentagem de domicílios com cinco ou mais moradores). Foi calculada a incidência da co-infecção HIV/TB para cada nível socioeconômico. RESULTADOS: A co-infecção HIV/TB acometeu mais adultos do sexo masculino em idade economicamente ativa e a forma pulmonar da TB foi a mais comum. A distribuição espacial mostrou que as incidências nas áreas com níveis socioeconômicos intermediários e inferiores (8,3 e 11,5 casos por 100 mil habitantes, respectivamente) foram superiores àquela (4,8 casos por 100 mil habitantes) de nível socioeconômico superior. CONCLUSÕES: A taxa de incidência de co-infecção HIV/TB analisada por níveis socioeconômicos mostrou padraÞo espacial de distribuiçaÞo não homogêneo e apresentou valores mais altos em áreas de maior vulnerabilidade social. O estudo diagnosticou aìreas geograìficas prioritaìrias para o controle da co-infecção e a tecnologia do sistema de informação geográfica pode ser empregada no planejamento das ações em saúde pelos gestores municipais.

Mutagenic activity removal of selected disperse dye by photoeletrocatalytic treatment

The degradation of black dye commercial product (BDCP) composed of C.I. Disperse Blue 373, C.I. Disperse Orange 37, C.I. Disperse Violet 93 dyes was investigated by photoelectrocatalysis process. The dyes have shown high mutagenic activity with Salmonella strain YG1041 and TA98 with and without S9. Samples of BCPD dye submitted to conventional chlorination and photoelectrocatalytic oxidation were compared monitoring its products by HPLC using a diode array detector, spectrophotometry UV-vis, TOC removal, and mutagenicity potency. The photoelectrocatalytic method operating with Ti/TiO(2) as anode at +1.0 V and UV illumination presented fast oxidation of test solutions containing 10 mg L(-1) of dye in 0.1 mol L(-1) NaCl pH 4.0 leading to 100% of discoloration, 67% of mineralization, and negative response to all tested Salmonella strains. The formation of Cl(aEuro cent), CL(2) (aEuro cent) on photoelectrocatalytic medium improved the efficiency of the method in relation to conventional chlorination method that promoted 100% of discoloration, but only 8% of TOC removal and more mutagenic product.

Non-N-methyl-d-aspartate glutamate receptors in the lateral hypothalamus modulate cardiac baroreflex responses in conscious rats

P>In the present study, we investigated the effects of inhibition of the lateral hypothalamus (LH) neurotransmission with bilateral microinjection of CoCl(2), a non-selective blocker of neurotransmission, on modulation of cardiac baroreflex responses in conscious rats as well as the involvement of LH glutamatergic neurotransmission in this modulation. Reflex bradycardiac and tachycardiac responses to blood pressure increases (following i.v. infusion of phenylephrine) or decreases (following i.v. infusion of sodium nitroprusside) were investigated in conscious male Wistar rats. Responses were evaluated before and after microinjection of 1 nmol/100 nL CoCl(2), 2 nmol/100 nL 1,2,3,4-tetrahydro-6-nitro-2,3-dioxobenzoquinoxaline-7-sulphonamide (NBQX; a selective non-N-methyl-d-aspartate (NMDA) glutamate receptor antagonist) or different doses (2, 4 or 8 nmol/100 nL) of the selective NMDA glutamate receptor antagonist LY235959. Microinjection of CoCl(2) into the LH had no effect on the tachycardiac baroreflex response, but did evoke a decrease in the reflex bradycardia caused by increases in blood pressure. Microinjection of NBQX into the LH had a similar effect on reflex bradycardia as CoCl(2), but had no effect on the tachycardiac response. Microinjection of increasing doses of LY235959 into the LH had no effect on the cardiac baroreflex response. In conclusion, the data suggest that the LH has a tonic facilitatory influence on the parasympathetic component of the baroreflex. The results also indicate that this facilitatory influence is mediated by local LH glutamatergic neurotransmission through non-NMDA glutamatergic receptors.

Cardiovascular responses to different stages of restorative dental treatment unaffected by local anaesthetic type

Background: The aim of this study was to evaluate the cardiovascular effects of maxillary infiltration using 2% lidocaine with 1: 100 000 adrenaline, 4% articaine with 1: 200 000 adrenaline, and 4% articaine with 1: 100 000 adrenaline in different stages during restorative dental procedures. Methods: Twenty healthy patients randomly received 1.8 mL of the three local anaesthetics. Systolic blood pressure, average blood pressure, diastolic blood pressure, and heart rate were evaluated by the oscillometric and photoplethysmograph methods in seven stages during the appointment. Results: Statistical analysis by ANOVA and Tukey tests of cardiovascular parameters did not show significant differences between the anaesthetic associations. There were significant differences for the parameters among different clinical stages. Conclusions: The variation of cardiovascular parameters was similar for lidocaine and articaine with both adrenaline concentrations and showed no advantage of one drug over the other. Cardiovascular parameters were influenced by the stages of the dental procedures, which showed the effect of anxiety during restorative dental treatment.

Six-month evaluation of adhesives interface created by a hydrophobic adhesive to acid-etched ethanol-wet bonded dentine with simplified dehydration protocols

Objectives: To evaluate the efficacy of simplified dehydration protocols, in the absence of tubular occlusion, on bond strength and interfacial nanoleakage of a hydrophobic experimental adhesive blend to acid-etched, ethanol-dehydrated dentine immediately and after 6 months. Methods: Molars were randomly assigned to 6 treatment groups (n = 5). Under pulpal pressure simulation, dentine crowns were acid-etched with 35% H(3)PO(4) and rinsed with water. Adper Scotchbond Multi-Purpose was used for the control group. The remaining groups had their dentine surface dehydrated with ethanol solutions: group 1 = 50%, 70%, 80%, 95% and 3 x 100%, 30 s for each application; group 2 the same ethanol sequence with 15 s for each solution; groups 3, 4 and 5 used 100% ethanol only, applied in seven, three or one 30 s step, respectively. After dehydration, a primer (50% BisGMA + TEGDMA, 50% ethanol) was used, followed by the neat comonomer adhesive application. Resin composite build-ups were then prepared using an incremental technique. Specimens were stored for 24 h, sectioned into beams and stressed to failure after 24 h or after 6 months of artificial ageing. Interfacial silver leakage evaluation was performed for both storage periods (n = 5 per subgroup). Results: Group 1 showed higher bond strengths at 24 h or after 6 months of ageing (45.6 +/- 5.9(a)/43.1 +/- 3.2(a) MPa) and lower silver impregnation. Bond strength results were statistically similar to control group (41.2 +/- 3.3(ab)/38.3 +/- 4.0(ab) MPa), group 2 (40.0 +/- 3.1(ab)/38.6 +/- 3.2(ab) MPa), and group 3 at 24 h (35.5 +/- 4.3(ab) MPa). Groups 4 (34.6 +/- 5.7(bc)/25.9 +/- 4.1(c) MPa) and 5 (24.7 +/- 4.9(c)/18.2 +/- 4.2(c) MPa) resulted in lower bond strengths, extensive interfacial nanoleakage and more prominent reductions (up to 25%) in bond strengths after 6 months of ageing. Conclusions: Simplified dehydration protocols using one or three 100% ethanol applications should be avoided for the ethanol-wet bonding technique in the absence of tubular occlusion, as they showed decreased bond strength, more severe nanoleakage and reduced bond stability over time.

The Effect of Different Fluoride Concentrations and pH of Dentifrices on Plaque and Nail Fluoride Levels in Young Children

To evaluate the influence of dentifrice pH and fluoride (F) concentration on F uptake by plaque and nails, two sets of 5-to 6-year-old children were randomly allocated into four groups, according to the type of dentifrice they had been using for 1 year: (1) experimental liquid dentifrice (ELD), 1,100 ppm F, pH 7.0; (2) ELD, 1,100 ppm F, pH 4.5; (3) ELD, 550 ppm F, pH 4.5, and (4) commercial toothpaste, 1,100 ppm F, pH 7.0. In one set of children, nails were clipped. In the second, plaque samples were collected 1 h after the last use of dentifrice. F concentration in plaque and nails was analyzed. Plaque F concentration was significantly lower in group 4 than in groups 1-3. Nail F concentration was significantly higher in group 4, and significantly lower in group 3, than in group 1 or 2. Plaque F uptake was influenced significantly by dentifrice consistency and nonsignificantly by pH and F concentration. Reduction of dentifrice pH did not affect nail F concentration.

Aspectos epidemiológicos da tuberculose em menores de 15 anos no Município de São Paulo, Brasil, 1984

Foram estudados todos os casos de tuberculose, referentes a 1984, envolvendo população residente no Município de São Paulo, SP, Brasil, na faixa etária de menores de 15 anos, cujo diagnóstico foi notificado ao Centro de Informações da Saúde da Secretaria de Estado da Saúde (SP). Foram analisados os prontuários em cada instituição que fez a notificação e realizadas entrevistas com os médicos responsáveis pelos casos. A incidência foi de 21,4/100.000 nos menores de 15 anos, a maior ocorrendo no grupo etário de menores de 5 anos (31,8/100.000 habitantes). Foram encontradas grandes diferenças entre os coeficientes correspondentes às diversas regiões do Município. A forma de tuberculose mais freqüente foi a pulmonar (83,1%-17,8/100.000) enquanto que a extrapulmonar foi de 12,2% (2,5/100.000) e a pulmonar associada a outras localizações extrapulmonares, de 4,7% (1,0/100.000 habitantes). Foram encontrados 46 casos com BK + correspondendo a 37,7% dos exames realizados, em material de origem pulmonar, e 16 casos com BK + (53,3% dos exames realizados), em material extrapulmonar. O coeficiente de incidência de casos com baciloscopia positiva de escarro foi de 0,9/100.000, sendo maior na idade de 10 a 14 anos (2,8/100.000).

Incidence rate and spatio-temporal clustering of type 1 diabetes in Santiago, Chile, from 1997 to 1998

OBJECTIVE: To estimate the incidence rate of type 1 diabetes in the urban area of Santiago, Chile, from March 21, 1997 to March 20, 1998, and to assess the spatio-temporal clustering of cases during that period. METHODS: All sixty-one incident cases were located temporally (day of diagnosis) and spatially (place of residence) in the area of study. Knox's method was used to assess spatio-temporal clustering of incident cases. RESULTS: The overall incidence rate of type 1 diabetes was 4.11 cases per 100,000 children aged less than 15 years per year (95% confidence interval: 3.06--5.14). The incidence rate seems to have increased since the last estimate of the incidence calculated for the years 1986--1992 in the metropolitan region of Santiago. Different combinations of space-time intervals have been evaluated to assess spatio-temporal clustering. The smallest p-value was found for the combination of critical distances of 750 meters and 60 days (uncorrected p-value = 0.048). CONCLUSIONS: Although these are preliminary results regarding space-time clustering in Santiago, exploratory analysis of the data method would suggest a possible aggregation of incident cases in space-time coordinates.

Multiple skin neoplasms in subjects under 40 years of age in Goiania, Brazil

OBJECTIVE To describe the trend for malignant skin neoplasms in subjects under 40 years of age in a region with high ultraviolet radiation indices.METHODS A descriptive epidemiological study on melanoma and nonmelanoma skin cancers that was conducted in Goiania, Midwest Brazil, with 1,688 people under 40 years of age, between 1988 and 2009. Cases were obtained fromRegistro de Câncer de Base Populacional de Goiânia(Goiania’s Population-Based Cancer File). Frequency, trends, and incidence of cases with single and multiple lesions were analyzed; transplants and genetic skin diseases were found in cases with multiple lesions.RESULTS Over the period, 1,995 skin cancer cases were observed to found, of which 1,524 (90.3%) cases had single lesions and 164 (9.7%) had multiple lesions. Regarding single lesions, incidence on men was observed to have risen from 2.4 to 3.1/100,000 inhabitants; it differed significantly for women, shifting from 2.3 to 5.3/100,000 (Annual percentage change – [APC] 3.0%, p = 0.006). Regarding multiple lesions, incidence on men was observed to have risen from 0.30 to 0.98/100,000 inhabitants; for women, it rose from 0.43 to 1.16/100,000 (APC 8.6%, p = 0.003). Genetic skin diseases or transplants were found to have been correlated with 10.0% of cases with multiple lesions – an average of 5.1 lesions per patient. The average was 2.5 in cases without that correlation.CONCLUSIONS Skin cancer on women under 40 years of age has been observed to be increasing for both cases with single and multiple lesions. It is not unusual to find multiple tumors in young people – in most cases, they are not associated with genetic skin diseases or transplants. It is necessary to avoid excessive exposure to ultraviolet radiation from childhood.
