Entre la fin du régime français et l’adoption de l’Acte constitutionnel par le Parlement de Londres en 1791, le rapport que la noblesse canadienne entretient avec le système judiciaire civil de la colonie change de façon majeure. Les Canadiens doivent s’adapter au nouveau système mis en place par l’administration britannique de la colonie. En Nouvelle-France, les nobles présentaient leurs différends juridiques civils devant le Tribunal royal, régi par la Coutume de Paris ; à partir de la Cession (1763), ce sont officiellement les lois britanniques qui s’appliquent jusqu’au retour des lois civiles françaises en 1774. Après quelques adaptations, la Cour des Plaidoyers communs devient la cour de prédilection des Canadiens, et par conséquent, de l’ancienne élite militaire. Le système judiciaire constitue un élément important de l’étude de l’évolution de la colonie, car l’attitude de la caste élitaire face aux tribunaux est un indicateur de sa capacité d’adaptation et de son degré d’implication dans la vie sociale.

A violência sempre foi um fenómeno inerente à vida humana, por isso abordá-la no passado implica o conhecimento das variáveis que a condicionam. Nesta dissertação quisemos comprovar que são os factores sociais (género, estado civil), económicos (ocupações) e culturais (códigos morais vigentes)os que mais condicionam as práticas violentas na região em estudo. Por outro lado, procurámos perceber se a acção do Estado, com uma crescente influência no quotidiano dos indivíduos, fruto de uma forma própria de governar durante a segunda metade do século, condicionaram as práticas de violência, nomeadamente através de alterações legislativas, organização judiciale práticas de vigilância. Quisemos ainda compreender se alguns factores conjunturais, como altas de preços, sublevações populares, maiores fluxos migratórios e crescimento demográfico, são determinantes para a evolução quantitativa e qualitativa da violência. Para isso, baseámo-nos num corpo documental constituído, maioritariamente, por escrituras de perdão de parte (pela ausência de processos judiciais para o período em estudo), legislação, correspondência da Intendência Geral da Polícia e do Ministério do Reino, além de outros fundos de origem municipal.

O repertório português para instrumentos de tecla da segunda metade do século XVIII encontra-se disperso em bibliotecas e arquivos, em Portugal e no estrangeiro, essencialmente sob a forma de manuscrito. Neste repertório, a sonata emerge como um género musical de grande importância. De facto, as duas coleções de sonatas publicadas na época constituem as únicas obras para instrumentos de tecla impressas em Portugal durante todo esse século. O objetivo deste trabalho é realizar um inventário do repertório português composto para instrumentos de tecla durante o período acima descrito, focando a respectiva descrição formal e as características composicionais das sonatas em geral, e na produção de cada compositor português em particular, bem como as suas biografias e perfis. De forma a estudar a sonata portuguesa e o seu desenvolvimento no período compreendido entre 1750–1807, foi realizado um levantamento das obras portuguesas existentes para instrumentos de tecla deste período. Este levantamento foi acompanhado por pesquisas biográficas sobre cada compositor e por uma abordagem analítica baseada na Teoria da Sonata de James Hepokoski e Warren Darcy. A divisão deste período em dois subperíodos demonstra variações significativas na evolução da sonata portuguesa. O estudo deste repertório demonstra que a sonata é o género musical predominante e define o modelo da sonata portuguesa deste período, para além de caracterizar o desenvolvimento da sonata em Portugal em paralelo com o desenvolvimento deste género musical em Itália e Espanha; ABSTRACT: The Sonata Genre in Portugal: Contributions for the Study of the Portuguese Keyboard Repertory from 1750 to 1807 The extant Portuguese repertory of the second half of the eighteenth century for keyboard instruments is dispersed in libraries and archives, in Portugal and abroad, mainly in manuscript form. In that repertory, the sonata emerges as a genre of great importance. Indeed, the two collections of sonatas published at the time are the only works for keyboard instruments printed in Portugal throughout the entire century. The aim of the present work is to make an inventory of the Portuguese repertory written for keyboard instruments during the above-mentioned period, with a focus on its formal description and the compositional characteristics of the sonatas in general and in the production of each Portuguese composer in particular, in addition to the biographies and profiles of the latter. In order to study the Portuguese sonata and its development in the period comprised between 1750–1807, a survey of the existing Portuguese works for keyboard instruments from that period was done. This survey was followed by a research on the biography of each composer and an analytic approach based on the Sonata Theory by James Hepokoski and Warren Darcy. Dividing this period in two sub periods showed significant variations on the evolution of the Portuguese sonata. The study of this repertory shows that the sonata is the predominant musical genre within it and identifies the Portuguese sonata model of this period, besides characterizing the development of the sonata in Portugal in parallel with the development of the same genre in Italy and Spain.

O presente estudo trata da prática política nos diferentes espaços das monarquias ibéricas na primeira metade do século XVIII. Tendo como objecto de análise principal a correspondência de quatro municípios seleccionados como observatórios (Évora, Córdova, Ouro Preto e Quito), pretende-se conhecer com maior detalhe as variações desta mesma prática em função dos contextos. Partindo da ideia de que o modelo político-administrativo implementado na América seria, na essência, decalcado do peninsular, procura-se aqui entender as mutações resultantes desta transferência. Ao longo deste trabalho defender-se-á a ideia de que, apesar das semelhanças entre o aparelho burocrático metropolitano e americano, a prática política nos territórios extra-europeus revestia-se de um conjunto de especificidades que a diferenciavam de forma clara. Neste sentido, argumenta-se que estas mutações condicionavam igualmente quais seriam os interlocutores das coroas nas diferentes regiões. Ou seja, que uma mesma instância teria, nos territórios ultramarinos e peninsulares, graus de participação nos processos de negociação e articulação política consideravelmente diferentes, algo que de que os municípios são um bom exemplo. Para o efeito serão comparados aspectos como os ritmos da comunicação; o relevo de cada instância na comunicação com a coroa; o perfil dos indivíduos que, nos diferentes territórios, ocupavam os ofícios da malha administrativa; as dinâmicas de especialização de competências ou de concentração de funções num mesmo cargo; a conflitualidade institucional e a existência de iniciativas políticas de cariz supramunicipal; Abstract: This study deals with the political practice in different areas of the Iberian monarchies in the first half of the eighteenth century. The main object of study is the correspondence of four selected municipalities (Évora, Cordoba, Ouro Preto and Quito), and it aims to know in greater detail the variations of this same practice on different contexts. Starting from the idea that the political and administrative model implemented in America would, in essence, be modeled on the peninsular, the intent is to understand the changes resulting from this transfer. Throughout this work we will argue that, despite the similarities between the metropolitan and American bureaucracy, political practice in non-European territories possessed a set of characteristics that were very specific. In this sense, it is argued that these mutations would also determine which would be the interlocutors of the crowns in different regions. That is, if the same instance would, in the overseas and peninsular territories, have different levels of participation in the negotiation and in the political articulation processes, something that municipalities are a good example of. For this purpose, aspects such as the rhythms of communication; the importance of each instance in the correspondence with the crown; the profile of the individuals who, in different territories, occupied the offices of the administrative network; the dynamics of specialization or concentration of functions in the same position; the institutional conflicts and the existence of supramunicipal initiatives will be compared.

Introducción En este trabajo presentamos una reconstitución de  las estadísticas parroquiales de bautizos, entierros y matrimonios en el periodo 1750-1900. A nadie escapa el interés múltiple de estas series y en particular su importancia para los estudios demográficos.  Los archivos parroquiales son una fuente insustituible para el conocimiento de los fenómenos  vitales antes de que  el Estado asumiera el registro y compilación estadística de esos datos. En Costa Rica, ellos ocurrieron entre 1883 y 1888, con la creación de la Dirección General de Estadística y Censos, la secularización de los cementerios, y la organización del Registro Civil. Por eso mismo también, el estudio concluye en 1900. El inicio en 1750 se justifica por la conservación y calidad de los registros parroquiales. Lo que existe antes de esos años es apenas fragmentario.

β-Carotene, zeaxanthin, lutein, β-cryptoxanthin, and lycopene are liposoluble pigments widely distributed in vegetables and fruits and, after ingestion, these compounds are usually detected in human blood plasma. In this study, we evaluated their potential to inhibit hemolysis of human erythrocytes, as mediated by the toxicity of peroxyl radicals (ROO•). Thus, 2,2'-azobis (2-methylpropionamidine) dihydrochloride (AAPH) was used as ROO• generator and the hemolysis assay was carried out in experimental conditions optimized by response surface methodology, and successfully adapted to microplate assay. The optimized conditions were verified at 30 × 10(6) cells/mL, 17 mM of AAPH for 3 h, at which 48 ± 5% of hemolysis was achieved in freshly isolated erythrocytes. Among the tested carotenoids, lycopene (IC(50) = 0.24 ± 0.05 μM) was the most efficient to prevent the hemolysis, followed by β-carotene (0.32 ± 0.02 μM), lutein (0.38 ± 0.02 μM), and zeaxanthin (0.43 ± 0.02 μM). These carotenoids were at least 5 times more effective than quercetin, trolox, and ascorbic acid (positive controls). β-Cryptoxanthin did not present any erythroprotective effect, but rather induced a hemolytic effect at the highest tested concentration (3 μM). These results suggest that selected carotenoids may have potential to act as important erythroprotective agents by preventing ROO•-induced toxicity in human erythrocytes.

The South Atlantic Magnetic Anomaly (SAMA) is one of the most outstanding anomalies of the geomagnetic field. The SAMA secular variation was obtained and compared to the evolution of other anomalies using spherical harmonic field models for the 1590-2005 period. An analysis of data from four South American observatories shows how this large scale anomaly affected their measurements. Since SAMA is a low total field anomaly, the field was separated into its nondipolar, quadrupolar and octupolar parts. The time evolution of the non-dipole/total, quadrupolar/total and octupolar/total field ratios yielded increasingly high values for the South Atlantic since 1750. The SAMA evolution is compared to the evolution of other large scale surface geomagnetic features like the North and the South Pole and the Siberia High, and this comparison shows the intensity equilibrium between these anomalies in both hemispheres. The analysis of non-dipole fields in historical period suggests that SAMA is governed by (i) quadrupolar field for drift, and (ii) quadrupolar and octupolar fields for intensity and area of influence. Furthermore, our study reinforces the possibility that SAMA may be related to reverse fluxes in the outer core under the South Atlantic region.

Context. The luminous material in clusters of galaxies exists in two forms: the visible galaxies and the X-ray emitting intra-cluster medium. The hot intra-cluster gas is the major observed baryonic component of clusters, about six times more massive than the stellar component. The mass contained within visible galaxies is approximately 3% of the dynamical mass. Aims. Our aim was to analyze both baryonic components, combining X-ray and optical data of a sample of five galaxy clusters (Abell 496, 1689, 2050, 2631 and 2667), within the redshift range 0.03 < z < 0.3. We determined the contribution of stars in galaxies and the intra-cluster medium to the total baryon budget. Methods. We used public XMM-Newton data to determine the gas mass and to obtain the X-ray substructures. Using the optical counterparts from SDSS or CFHT we determined the stellar contribution. Results. We examine the relative contribution of galaxies, intra-cluster light and intra-cluster medium to baryon budget in clusters through the stellar-to-gas mass ratio, estimated with recent data. We find that the stellar-to-gas mass ratio within r(500) (the radius within which the mean cluster density exceeds the critical density by a factor of 500), is anti-correlated with the ICM temperature, which range from 24% to 6% while the temperature ranges from 4.0 to 8.3 keV. This indicates that less massive cold clusters are more prolific star forming environments than massive hot clusters.

It has been demonstrated that laser induced breakdown spectrometry (LIBS) can be used as an alternative method for the determination of macro (P, K. Ca, Mg) and micronutrients (B, Fe, Cu, Mn, Zn) in pellets of plant materials. However, information is required regarding the sample preparation for plant analysis by LIBS. In this work, methods involving cryogenic grinding and planetary ball milling were evaluated for leaves comminution before pellets preparation. The particle sizes were associated to chemical sample properties such as fiber and cellulose contents, as well as to pellets porosity and density. The pellets were ablated at 30 different sites by applying 25 laser pulses per site (Nd:YAG@1064 nm, 5 ns, 10 Hz, 25J cm(-2)). The plasma emission collected by lenses was directed through an optical fiber towards a high resolution echelle spectrometer equipped with an ICCD. Delay time and integration time gate were fixed at 2.0 and 4.5 mu s, respectively. Experiments carried out with pellets of sugarcane, orange tree and soy leaves showed a significant effect of the plant species for choosing the most appropriate grinding conditions. By using ball milling with agate materials, 20 min grinding for orange tree and soy, and 60 min for sugarcane leaves led to particle size distributions generally lower than 75 mu m. Cryogenic grinding yielded similar particle size distributions after 10 min for orange tree, 20 min for soy and 30 min for sugarcane leaves. There was up to 50% emission signal enhancement on LIBS measurements for most elements by improving particle size distribution and consequently the pellet porosity. (C) 2011 Elsevier B.V.

The objective of this study was to evaluate the sensory stability of ultra-high temperature (UHT) milk subjected to different heat treatments and stored at room temperature in white high density polyethylene bottles (HDPE) pigmented with titanium dioxide. Two lots of 300 units each were processed, respectively, at 135 and 141 degrees C/10 s using indirect heating and subsequently aseptically filled in an ISO class 7 clean room. These experimental lots were evaluated for appearance, aroma, flavor, and overall appreciation and compared to samples of commercial UHT milk purchased from local commercial stores. The time-temperature combinations investigated did not affect either the acceptability or the shelf life of the milk. Despite the limited light barrier properties of HDPE bottles, the product contained in the package tested exhibited good stability, with a shelf life ranging from 4 to 11 wk. Within this time period, the acceptability of the experimental lots was similar to that of the commercial products. The results achieved in this study contribute to turn the low-cost UHT system investigated into a technically viable option for small-size dairy processing plants.

Frozen samples of mechanically deboned chicken meat (MDCM) with skin were irradiated with gamma radiation doses of 0.0 kGy (control) and 3 kGy at 2 different radiation dose rates: 0.32 kGy/h (3 kGy) and 4.04 kGy/h (3 kGy). Batches of irradiated and control samples were evaluated during 11 d of refrigerated (2 +/- 1 degrees C) storage for the following parameters: total psychrotrophic bacteria count, thiobarbituric acid reactive substances (TBARS), evaluation of objective color (L*, a*, and b*) and a sensory evaluation (irradiated odor, oxidized odor, pink and brown colors). No statistical difference (P > 0.05) was found amongst the TBARS values obtained for the MDCM samples irradiated with dose rates of 0.32 and 4.04 kGy/h. There was a significant increase (P < 0.05) in the psychrotrophic bacterial count as from the 7th day of refrigerated storage, for the MDCM samples irradiated at the dose rate of 4.04 kGy/h. With respect to the attribute of oxidized odor, the samples irradiated with a dose rate of 0.32 kGy/h showed a stronger intensity and were significantly different (P < 0.05) from the sample irradiated with a dose rate of 4.04 kGy/h on days 0 and 2 of refrigerated storage. Irradiation with a dose rate of 4.04 kGy/h (3 kGy) was shown to be the best condition for the processing of MDCM according to the evaluation of all the variables, under the conditions of this study. Practical Application The results obtained for the application of different dose rates of ionizing radiation to mechanically deboned chicken meat will provide the food industry with information concerning the definition of the best processing conditions to maximize the sensory and food quality.

Desserts made with soy cream, which are oil-in-water emulsions, are widely consumed by lactose-intolerant individuals in Brazil. In this regard, this study aimed at using response surface methodology (RSM) to optimize the sensory attributes of a soy-based emulsion over a range of pink guava juice (GJ: 22% to 32%) and soy protein (SP: 1% to 3%). WHC and backscattering were analyzed after 72 h of storage at 7 degrees C. Furthermore, a rating test was performed to determine the degree of liking of color, taste, creaminess, appearance, and overall acceptability. The data showed that the samples were stable against gravity and storage. The models developed by RSM adequately described the creaminess, taste, and appearance of the emulsions. The response surface of the desirability function was used successfully in the optimization of the sensory properties of dairy-free emulsions, suggesting that a product with 30.35% GJ and 3% SP was the best combination of these components. The optimized sample presented suitable sensory properties, in addition to being a source of dietary fiber, iron, copper, and ascorbic acid.
