Leroyer, Dominique. "D'un secret qui n'en serait pas un... : paradoxes communicationnels du "secret maçonnique"". Electronic Thesis or Diss., Bourgogne Franche-Comté, 2023. http://www.theses.fr/2023UBFCH022.
Masonry first appeared in England in 1717, and spread to France in the following years. Three centuries after its birth, it still does not have a stabilised image, so much so that it is traversed by contradictory paradigms of representation.In this mediation, "secrecy" was to become a divisive element of representation, federating the darker imaginations of masonry, the one on which the most hostile and least rational arguments were grafted.However, regular masonry in France, as it was expressed in the eighteenth century, first by the Grande Loge de France, then by the Grand Orient de France, later enriched by other Obediences, was never a secret society.From the outset, like English masonry, French masonry was known and recognisable in its structure, its workings, its writings and its aims. Its detractors have had no choice but to draw on the vast literature available to them to combat it politically and socially, using the media to create a false image of what it is and fabricating the assertion that masonry is inherently secretive.The ambiguity of the word "secret" has allowed this amalgam to take place, insofar as Freemasonry, on another dimension, has claimed the secrecy and esotericism that constitute another facet of it, on a spiritual and maieutic level. Thanks to this ambivalence, masonic secrecy has given rise to an ambiguous representation of masonry, of which it forms the signifying background, because it is always through it, and in relation to it, that the various discourses on masonry are positioned.This discourse on masonic secrecy, from the eighteenth century to the present day, is organised around a double communicational paradox.The first communicational paradox is constituted by the following oxymoron: to state as secret something that is public. This is an oxymoron of the proposition, because what is public, by nature, is not secret; a paradox as a result of the proposition that affirms the existence of a masonic secret despite the factual evidence of its non-existence.Established by the literature of masonic disclosure (1738-1789), we will analyse the discursive mechanisms of this first communicational paradox, which infuses the discourse on Masonry by associating it with secrecy even though it is factually totally accessible and knowable.The second paradox, which builds on the first and develops it further, aims to make masonry essential to this non-existent secret. It originated with the Papal Bulls of CLÉMENT XII and BENOÎT XIV, and above all, in 1798, with the writings of Augustin BARRUEL following the shock of the French Revolution. This essentialisation creates an image of masonry that is far removed from its organisational, ideological and human reality, and on which its opponents are free to attach negative attributes in order to combat it more effectively.The discourse of masonic secrecy, by denying masonry its objective reality, thus becomes the discourse of an environment, social and political, deeply rooted in history, hostile to it, as much for what it is as for what it represents. The discourse on masonic secrecy becomes the place where reactionary interdiscourses crystallise. Since 1789, other discourses have circulated through the anti-masonicism of secrecy, first counter-revolutionary, then anti-republican, anti-semitic and now conspiracy. Paradoxically, dictionaries, first and foremost that of the Académie française, guarantors of the episteme in the social body, were a place where this doxa was propagated.Present for several centuries in many discourses and channels of communication, the masonic secret, as a communicational paradox, is a myth, in the sense that Roland BARTHES understands it, which durably and profoundly structures the representation of freemasonry in Society
Branco, Danielle Paes Machado de Andrade. "O comportamento em campo aberto como modelo para avaliar a recuperação funcional após lesão unilateral dos barris do córtex somatossensorial". Universidade do Estado do Rio de Janeiro, 2011. http://www.bdtd.uerj.br/tde_busca/arquivo.php?codArquivo=3831.
Em roedores, as vibrissas são detectores táteis que desempenham papel importante na exploração espacial do ambiente e na discriminação de texturas. No córtex somatosensorial, os campos receptivos de cada uma das vibrissas estão organizados no hemisfério contralateral em colunas discretas denominadas barris. A lesão unilateral dos barris produz um comportamento assimétrico caracterizado pela redução no uso da vibrissa contralateral à lesão na exploração do ambiente, assimetria esta que diminui progressivamente na medida em que os animais são repetidamente testados. Em ratos, este comportamento, normalmente medido pelo número de vezes que os animais encostam as vibrissas na parede de um campo aberto, tem se mostrado uma ferramenta importante em estudos de plasticidade e recuperação funcional após lesões corticais. Contudo, em camundongos com lesões unilaterais dos barris, o registro dos toques das vibrissas na parede tem levado a resultados contraditórios. Esse trabalho tem por objetivo principal o estabelecimento de um modelo comportamental para avaliação da recuperação funcional após lesões unilaterais dos barris do córtex somatosensorial em camundongos. Para tanto, o sentido dos deslocamentos realizados próximos às quinas do campo aberto foi registrado em camundongos Suíços machos submetidos à criolesão unilateral dos barris foi avaliado em três estudos independentes. No primeiro estudo, demonstramos que no grupo Criolesado houve um predomínio dos deslocamentos em sentido contralateral na primeira vez em que foram testados no campo aberto e este resultado foi independente do fato de na primeira sessão ter sido realizada um ou nove dias após a cirurgia. Além disso, demonstramos que o predomínio de deslocamentos em sentido contralateral foi diminuindo na medida em que os animais eram repetidamente testados no campo aberto. No segundo estudo, demonstramos que os animais do grupo Criolesado que foram previamente submetidos a cinco sessões experimentais no campo aberto não apresentaram, após a cirurgia, diferenças entre os deslocamentos realizados em sentido ipsolateral e contralateral à lesão. Já no terceiro estudo, demonstramos que os animais do grupo Criolesado que não foram previamente testados no campo aberto apresentam um predomínio de deslocamentos em sentido contralateral, mesmo quando o teste foi realizado 48 dias após a lesão unilateral dos barris. Nossos dados sugerem que o sentido dos deslocamentos próximo às quinas do campo aberto pode ser uma ferramenta importante para avaliar a recuperação das lesões unilaterais nos barris do córtex somatosensorial. Além disso, para avaliar a recuperação funcional após a lesão unilateral dos barris do córtex somatossensorial, sem o viés da habituação à situação do teste, os animais devem ser testados apenas uma vez
In rodents, the vibrissae are tactile detectors that have an important role in the spatial exploration of the environment and in texture discrimination. In the somatosensory cortex, the receptive fields of each of the vibrissae are organized into discrete columns, known as barrels, in the contralateral hemisphere. The unilateral lesions of the barrels results in an asymmetric behavior characterized by the reduction in the use of the vibrissae contralateral to the lesion during the exploration of the environment. This asymmetry progressively diminishes as the animal is repeatedly tested in the same environment. In rats, this behavior, usually assessed by the number of times the animals touch the walls of an open field arena with their vibrissae, has been considered a useful tool in studies addressing plasticity and functional recovery after cortical lesions. However, in mice with unilateral lesions of the barrels, the analysis of the number of times that the vibrissae touch the walls have lead to contradictory results. The present work aims to establish a behavioral model for the evaluation of functional recovery after unilateral lesions of the barrel field located in the somatosensory cortex of the mouse. To that end, the direction of movement near the corners of the open field of Swiss male mice subjected to unilateral cryolesion of the barrel was analyzed in three independent studies. In the first study, we demonstrated that the cryolesioned animals displayed a predominance of contralateral movements in the first time that they were tested in the open field and that this result was present whether the animals was first tested one or nine days after the lesion. Furthermore, we demonstrated that the predominance of movements toward the contralateral side of the lesion diminished as the animals were repeatedly tested in the open field. In the second study, we demonstrated that the cryolesioned animals that were, prior to barrel field lesioning, subjected to five sessions in the open field did not display, after lesioning, differences between the number of ipso and contralateral movements. In the third study, we demonstrated that the cryolesioned animals that were not previously tested in the open field displayed a predominance of contralateral movements even if the first test was carried out forty eight days after the unilateral lesion of the barrels. Our data suggest that the analysis of the direction of movement near the corners of the open field can be an important tool in the assessment of functional recovery after unilateral lesions of the barrels located in the somatosensory cortex of mice. Moreover, in order to properly assess functional recovery after unilateral lesion of the barrel field without the confounding factor of habituation, animals must be tested only once

Background: Each year the immigration increases in Sweden, as an effect of that, more individuals from other countries and cultures seek help from the healthcare system. The Swedish law states that healthcare providers have an obligation to give each individual equal care. Because communication is a big part of the meeting between the caregiver and the patient, the language and cultural barriers could lead to a lack of care. This also means that healthcare providers may experience a sense of frustration. Objective: The aim of the study was to elucidate and explore clinical dietitians’ experiences of language and cultural barriers during the meeting with patients with a first language other than Swedish. Method: Based on a qualitative research method six clinical dietitians were interviewed. During the interviews a semi-structured interview guide was used. The interviews were recorded and transcribed verbatim. The data was analyzed withqualitative content analysis. Results: In order to give patients good care the dietitians had to use creative approaches to overcome language and cultural barriers. The interpreter was seen as one of the most important instrument during the meeting with the patient, but an interpreter who did not carry out their work in a good way could affect the meeting negatively. The informants felt that communication difficulties could lead to unsuccessful treatmentwhen the message did not reach the patients. This led to a sense of failure and frustration among the informants. Conclusions: Language and cultural barriers can be an obstacle in order to give the patient the care the dietitian wishes. Despite creative solutions and the use of an interpreter there is a risk that the quality of care does not reach the demands according to the Swedish legislation. In conjunction with increased immigration, procedures and education on language and cultural barriers should be reviewed.

In recent decades, there has been an increase in beer consumption in Brazil and around the world. There are many methodologies and concepts that differentiate styles of beer, are the modifications of the production processes, use of various ingredients fermentations in fermenters of different types of packaging methodologies, wood use in beverage maturation, among others. Parallel to the development of scientific knowledge in microbiology, such as the growing understanding of cellular physiology, the immobilization techniques of brewing yeast and isolation of new strains that provide aromatic characteristics differentiated the beers. The storage of drinks in wooden barrels is widely used since antiquity in the production of drinks. The objective of this research was to evaluate the formation of some aromatic compounds at Ale type beer aging in wooden barrels, taking into account chemical and microbiological aspects such as: maturation of similar analyzing the content of phenolic compounds of low molecular weight determined by chromatography high performance liquid volatile counterparts (aldehydes, esters and higher alcohols) determined by gas chromatography using a flame ionization detector and microbiological properties of beer analyzing cell viability, different culture media for total yeast, bacteria acetic acid, Lactic acid bacteria and growth medium modified to Brettanomyces. The study was conducted in the microbrewery premises of the agribusiness department, food and nutrition Luiz de Queiroz College of Agriculture, Piracicaba (SP). The primary fermentation was conducted at 23° C in tapered cylindrical stainless steel fermenter after cooling to 0° beer was stored in barrels (50 liters) American oak at 25° C for three and five months. After maturation, a new beer (Young Ale) was produced and blended (blend) with the aged beer bottled and stored for analysis. After maturation, a new beer (Young Ale) was produced and mixed ( Blend ) with the beer aged in different proportions : Young beer Ale ; blends of 33 % and 66 % of aged beer; 100 % aged beer, the beers were bottled and stored for a period of three months to the beginning of the chemical, microbiological and sensory analysis. Microbial and chemical chenges accurred that favored increased complexity of the beer after passing through a storage period in oak barrel, and that changes was greater in proportion to the increase beer storage time.

Beer is a very popular alcoholic beverage in the world and the most widely consumed in Brazil. There are many styles of beer in the world that can be produced by changes in the production process, use of various ingredients, maturation using wood barrels and / or addition of wood fragments, and others. Wood maturation can provide aromatic complexity to alcoholic beverages, and the oak wood is widely used. The use of oak in the maturation of beer is the focus of this work. The beers matured at 0 °C for three months in glass bottles of 600 mL, oak barrels and plastic containers with oak cubes at a dose of 3g/L, with three different levels of toasting (light, medium, and high). Beers resulting from the different treatments were analyzed physico-chemically (alcohol content, pH, total acidity, turbidity, total phenolics, color and bitterness), the volatile compounds (aldehydes, esters and higher alcohols) by gas chromatography (FID), the low molecular weight phenolic compounds (gallic acid, 5-hydroxymethylfurfural, furfural, vanillic acid, syringic acid, vanillin, syringaldehyde, coniferaldehyde and sinapaldehyde) by High Performance Liquid Chromatography (HPLC), and sensory. The analysis shows that there were no qualities changes in beer that could be attributed to the storage in contact with oak wood. The volatile compounds had minor changes; the low molecular weight phenolic compounds were those with the greatest increases within three months of maturation. There was no difference in sensory acceptance between beers matured in oak barrel, oak cubes and glass bottles. This work suggests that wood influences sensory beer, but more studies are needed to be able to get a quality product that can satisfy the consumer and is accessible to the industry.
Jonas, Hartman. "Hemicellulose as barrier material". Licentiate thesis, KTH, Fibre and Polymer Technology, 2006. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-3907.
Polysaccharides constitute an important source of raw materials for the packaging industry today. Polysaccharides have good natural barrier properties which are necessary for packaging films. Cellulose is the forerunner among renewable polymers for such applications. Hemicelluloses represent a new interesting breed of barrier materials. We have chosen to work with the hemicellulose O-acetyl-galactoglucomannan (AcGGM). The high water solubility of this particular hemicellulose extracted from process waters is both an advantage and a limiting factor. However, through the right modification, the water sensitivity of AcGGM can be regulated.
This thesis presents four ways to modify AcGGM: (i) benzylation, (ii) plasma surface treatment followed by styrene addition, (iii) vapor-phase (VP) surface grafting with styrene, and (iv) lamination of an unmodified film with a benzylated material. The most important methods of analysis of the films produced include contact angle measurement, dynamic mechanical analysis under moisture scan, and oxygen gas permeability measurement.
It was found that unmodified AcGGM films have low oxygen permeability at intermediate relative humidity (50 % RH) and good dynamic mechanical properties over a wider humidity range. Films of benzylated material (BnGGM) exhibited a decrease in oxygen permeability at lower humidity but showed better tolerance to higher humidities and indicated better dynamic mechanical behavior than AcGGM films. Lamination proved to be the most promising technique of modification, combining the good gas barrier properties of AcGGM films with the moisture-insensitivity of the BnGGM films.

This thesis details the motivation, design, construction, and testing of the Gamma Intensity Monitor (GIM) for the Crystal-Barrel-Experiment at the Universität Bonn. The CB-ELSA collaboration studies the baryon excitation spectrum; resonances are produced by exciting nucleons in a polarized target with a linearly or circularly polarized, GeV-order photon beam. The photoproduced decay states are measured by a variety of detectors covering almost 4[pi] of the solid angle about the target. To measure the total cross section of these reactions, the total flux of photons through the target must be known to high accuracy. As the total cross section for nuclear photoproduction is low, counting the photons unscattered in the target is sufficiently accurate measurement of this quantity{this is the purpose of the Gamma Intensity Monitor. It is the final detector along the beam path and counts all photons that do not react with the target. The major design parameter is that the detector must consistently count GeV order photons at 10 MHz. This is accomplished by allowing the gammas to electronpositron pair produce within Ĉerenkov radiating PbF2 crystals. The Cerenkov light from these highly relativistic lepton pairs is measured with industrial photomultiplier tubes to provide an effective efficiency close to unity. Special bases were built for photomultiplier to ensure stable signal amplication even high count rates. Detailed descriptions of the GIM are provided to ensure that its inner working are completely transparent and to enable efficient operation and maintenance of the detector.

Kjellgren, Henrik. "Barrier properties of greaseproof paper". Licentiate thesis, Karlstad University, Division for Chemistry, 2005. http://urn.kb.se/resolve?urn=urn:nbn:se:kau:diva-1411.
The barrier properties of greaseproof paper are achieved by extensive beating of the fibres. This treatment results in high costs for energy, both as beating energy and drying energy. A full-scale trial has been performed to investigate the role of the pulp with respect to energy demand and the barrier properties of the final papers. The paper made of 100% sulphite pulp with a low degree of beating showed the lowest energy consumption at a given level of barrier properties such as air permeance, grease resistance and water vapour transmission rate.
The papers produced in the full-scale trial have been used as substrates for coating. Greaseproof paper has a closed surface and should therefore be a good base paper for barrier coatings.
Chitosan has been used as a barrier coating because of its good oxygen barrier properties. Moreover, chitosan is a renewable material. Coating trials on a bench-scale showed that greaseproof paper can be upgraded to provide a good oxygen barrier. The oxygen barrier could not be achieved on a pilot-scale using the metered size press technique, because of the low coat weight applied.
The influence of the base paper on the barrier properties of chitosan-coated paper has been investigated. It was found that greaseproof paper is better than a paper with a higher porosity. The coating seemed to stay more on the surface of the greaseproof papers and to form a continuous coating layer with better barrier properties.

Au cours du développement, les molécules de la famille des nétrines contribuent à la morphologénèse des organes en contrôlant la motilité et l'adhérence cellulaire. L'adhérence cellulaire entre les cellules endothéliales est une caractéristique importante de la barrière hémato-encéphalique (BHE), ce qui rend l'endothélium imperméable aux molécules sanguines et aux cellules immunitaires. Pour établir et maintenir cette barrière au cours du développement, à l'âge adulte et au cours de la maladie, les cellules endothéliales du cerveau doivent développer et maintenir ces contacts adhésifs en exprimant des molécules de jonction serrées. Cependant, nous ne savons pas si les molécules de la famille des nétrines influencent l'adhérence cellulaire inter-endothéliale de la BHE. Nous avons donc émis l'hypothèse que les nétrines resserrent la BHE au cours du développement, à l'âge adulte, et la protège au cours de la maladie.Méthodes: Pour valider notre hypothèse, nous avons utilisé des cellules endothéliales primaires dérivées des cerveaux humains adultes ou des cerveaux de souris nouveau-nés déficientes en nétrine-1 et évalué l'effet de la nétrine sur l'adhésion cellulaire endothéliale et inter-perméabilité de la barrière. Nous avons également évalué le potentiel thérapeutique des nétrines a restaurer la barrière et l'infiltration de cellules immunitaires limite dans le système nerveux central (SNC) pendant encéphalomyélite allergique expérimentale, un modèle animal de sclérose en plaques. Résultats: Nos résultats démontrent que les nétrines sont exprimées par les cellules endothéliales du cerveau, exprimes nétrines. Au cours du développement les nétrines aident à assurer l'étanchéité de la BHE. Chez les adultes, ils maintiennent et protègent la barrière adulte en augmentant l'expression des molécules de jonctions serrées, favorisant ainsi l'adhérence inter-endothéliale et diminuant les fuites de protéines à travers la BHE. Dans la pathologie de l'EAE, le rôle des nétrins diffère en fonction de la phase de la maladie. Au cours de la phase aigue, les nétrines atténuent la perte de l'intégrité de la BHE et diminuent l'infiltration des cellules myéloïdes dans le SNC. Ceci retarde l'apparition de la maladie et réduit sa sévérité. Au cours de la phase chronique de l'EAE, les souris traitées avec netrin-1 ont un plus grand nombre des cellules T activées dans leurs SNC et présentent une démarche ataxique ainsi qu'une spasticité des membres. Discussion: Nous concluons que les nétrins améliorent la stabilité de la BHE. Ces résultats suggèrent que les nétrines peuvent être envisagée comme agent thérapeutique dans les maladies neuroinflammatoire. Dans ce cas une approche précoce et à court terme serait probablement plus efficace.

Lyall, Evan Harrison. "Surround Integration During Active Sensation in the Mouse Barrel Cortex". Thesis, University of California, Berkeley, 2019. http://pqdtopen.proquest.com/#viewpdf?dispub=13422798.
Organisms scan their sensors around their environment to build an internal representation of that environment in a process known as active sensation. The integration of information across time and space is critical to providing context as to what is the organism is perceiving. However, the neural circuits that encode and underlie the integration of incoming sensory information have predominantly been studied in the context of passive sensation. Studying these circuits in the context of active sensation is imperative to generating a better understanding of how the brain naturally encodes sensation. This would have profound impacts on understanding the mechanisms of a number of neural disorders, including autism and attention-deficit/hyperactivity disorder, as well as how to improve the acuity of artificial sensation implanted into disabled individuals. To better understand how the mammalian brain encodes and integrates information during active sensation, my collaborators and I developed several novel paradigms to study surround integration in the mouse barrel cortex during active whisking. In Chapter 1 I establish why this is an important problem, and briefly summarize what is already known about sensory coding in the mouse whisker system. In Chapter 2 my collaborators and I probe how mice represent the location of an object within its whisking field, and how the integration of information across surround whiskers affects this representation. In doing so we discover a novel thalamocortical transformation where surround integration in the cortex suppresses activity in layer 4 of the cortex, ultimately generating a smooth map of scanned space in cortical layer 2/3. In Chapter 3 I utilize a novel tactile display to better understand the logic of multi-whisker integration in two cortical layers. In this unpublished work, I show that contrary to the previous literature in anesthetized mice, cortical neurons in awake, whisking mice powerfully summate specific whisker combinations supralinearly, generating a sparse code representing the entire combinatoric space of whisker touch. In Chapter 4, I conclude with some closing thoughts and propose some future lines of inquiry to further this research.
