Experimental evaluation of shear and compression strength of masonry wall before and after reinforcement: Deep repointing

Masonry presents some inadequacies due to its almost total lack of tensile strength. Typical damage to multiple leaf walls during earthquakes is the loss of bond between the leaves with consequent collapse of the external leaf. Retrofitting or repair of this damage is a very difficult task. In many cases grout injection or wall jacketing fail due to incompatibility with the construction technique of the walls. A complementary technique to the grouting has been proposed by the authors. Experimental results and applications of the technique on site have shown positive characteristics and the results of tests carried out on site show, in some cases, increases in shear strength and stiffness of the masonry walls

EFFECT OF FORMING PRESSURE ON THE REACTIVITY AND MICROSTRUCTURE OF ZIRCON POWDER COMPACTS

Preliminary results of a study on the effects of the forming pressure on the reactivity, sintering and microstructure of very fine natural zircon powder compacts. The effects of compaction pressure on the green densities and sintered densities are also discussed. The relationship between the density and the compaction pressure governs the mechanism that occurs in the consolidation process. The investigation has demonstrated changing the compaction pressure in the range 45-180MPa does not influence the onset temperature of sintering of powdered zircon (1150-1170 °C) but does influence the apparent density of the green compacts and consequently the porosity of the sintered specimens. Low relative density values were obtained in these sintering conditions

Profile of gamma-delta (γδ) T lymphocytes in the peripheral blood of crossbreed dogs during stages of life and implication in aging

Abstract Background: Data on gamma-delta (γδ) T lymphocytes in the peripheral blood of dogs are scant, related only to healthy pure breed dogs and limited to a restricted age range. The aim of the study was to investigate the modulation of the γδ T lymphocyte (TCRγδ+) subpopulation in peripheral blood of crossbreed healthy dogs according to five identified stages of life: Puppy, Junior, Adult, Mature, Senior and to determine its implication in aging. A rigorous method of recruitment was used to minimize the influence of internal or external pressure on the immune response. Twenty-three intact female and twenty-four intact male dogs were enrolled. Blood samples were collected and immunophenotyping of peripheral blood T lymphocytes and γδ T cell subpopulations was performed. Results: The percentage of γδ T cells in peripheral blood lymphocytes was comparable with the value of 2.5% published by Faldyna and co-workers (2001), despite the percentage reported was investigated in less arranged age range groups and coming from four different dog pure breeds, whereas our data were recorded on wider age range groups and coming from crossbreed dogs. Therefore, the γδ T cell percentage (2.5%) is consistent and points out that such value is breed-independent. Statistical analysis highlighted differences in both percentage and absolute γδ T cells according to the stage of life. γδ T cells decreased significantly in the peripheral blood of elder dogs (Senior group) in comparison with previous stages of life (Puppy, Junior, and Adult groups). Differences in γδ T cells are significant and they are reported, for the first time, related to dog aging. Conclusions: The study confirms dogs to be among the animals with a low TCRγδ+ cell profile. A decrease of the TCRγδ+ subpopulation percentage was observed in elder dogs. TCRγδ+ cells of group S were different from those of groups P, J, and A. The differences are reported for the first time in dog aging. Identifying the stage of life when the decrease of γδ T lymphocytes starts can be useful for providing a rationale for drafting a wellness plan trial to support thymus immune functions and mitigate its functional exhaustion

Eventos agudos em saúde mental

Na unidade Agressão e autoagressão você terá a oportunidade de estudar se que a violência, a agressão e a autoagressão são fenômenos refletidos na perspectiva de condições humanas. A patologização desses fenômenos fica evidente quando são promovidas rupturas sociais e quando determinados critérios técnicos são estabelecidos para interpretá-los. O acolhimento, o vínculo, a responsabilidade e a atuação em Rede Intersetorial são premissas para o cuidado nesta especificidade. Na unidade Alterações de comportamento é apresentado as principais alterações destacando-se os estados psicóticos agudos, a ansiedade e a depressão. Esses conceitos se originam de diferentes abordagens teóricas que determinam sua classificação. A organização Mundial da Saúde através do CID 10 é o que prevalece no campo dos diagnósticos descritivos em psiquiatria e saúde mental. O cuidado a pessoa em sofrimento psíquico grave segue a lógica da oferta das ações e serviços através da Rede de Atenção Psicossocial, onde o acolhimento e o Projeto Terapêutico Singular são elementos organizadores desse cuidado. Na unidade que trata de Problemas relacionados ao uso de substâncias psicoativas é abordado os saberes e as práticas relacionados ao uso abusivo de álcool, crack e outras drogas. Assim, foram indicadas as diferentes formas e os modelos de cuidado dos pacientes usuários de substâncias psicoativas, observando-se que apesar de cada uma dessas apresentar sua especificidade, as decisões terapêuticas devem considerar a pessoa que sofre e oportunizar sua participação efetiva na construção de seu projeto terapêutico.1.0UNA-SUSMinistério da Saúd

New "Green" approaches to the synthesis of pyrazole derivatives.

A novel approach to the synthesis of pyrazole derivatives from tosylhydrazones of alpha,beta-unsaturated carbonyl compounds possessing a beta-hydrogen is proposed, exploiting microwave (MW) activation coupled with solvent free reaction conditions. The cycloaddition was studied on three ketones (trans-4-phenyl-3-buten-2-one, beta-ionone and trans-chalcone). The corresponding 3,5-disubstituted-1H-pyrazoles were obtained in high yields and after short reaction times. In order to simplify and point out the green chemistry features of the method, a further improvement was achieved under the same catalytic conditions with a "one pot" synthesis of these heterocyclic compounds, starting directly from their carbonyl precursors via tosylhydrazones generated in situ. For an exhaustive study, the dielectric properties of the solid reaction mixtures were also measured, in order to obtain input data for the numerical simulation of their heating behaviour in the single mode MW cavity which was used for experimental work. In order to supply a valid methodology and tool for measuring the environmental impact, a comparative study between the synthetic route proposed and the classical synthetic route has been carried out

Literatura e cinema as possibilidades metodológicas viáveis como elementos básicos de comparação entre aspectos do contar- contos clássicos- através da Literatura e da Cinematologia.

O artigo busca como objetivo estabelecer procedimentos epistemológicos e metodológicos viáveis como elementos básicos de comparação entre aspectos do contar - contos clássicos - através da Literatura e da Cinematologia. Este concentra-se num estudo bibliográfico com demonstrações e possibilidades por meio dos diálogos dos autores dentre eles as habilidades e competências sobre os aspectos da Literatura e do Cinema. Essa pesquisa delimita-se via alguns diálogos entre autores sobre o que é literatura e o que é o cinema, falando também sobre o que são contos, como são suas personagens e as características representam a configuração dos contos de fadas, sejam como contos maravilhosos e fábulas ou mesmo como o que é o fantástico e o maravilhoso na literatura. Contudo, pode -se dizer que os contos de fadas são narrativas as quais, sempre marcam mudanças no contexto de seus personagens

Use of the international classification of diseases (ICD)-11 method applied to veterinary forensic pathology for coding the cause and manner of death in wildlife

The growth of human population has led, in recent years, to increasingly frequent contacts with the wild animals with which we share the territory, sometimes leading to negative interactions with them. The purpose of the study is to apply the codes contained in the 11th Revision of the International Classification of Diseases (ICD-11) method to investigate the cause and the manner of death, also to entrust the veterinarian with the task of recognizing and describing a suspected animal abuse as a sentinel indicator of violence toward humans and non-humans, thus expanding the concept of “One Health” from a forensic investigation perspective. The subjects recruited are wild mammals submitted for autopsy to the Pathology Unit of the Department of Veterinary Science, University of Parma, Italy, from 2015 to 2018. The manner and the cause of death of 167 wild animals of 16 different species have been investigated. When possible, an on-site inspection where the corpse was found was performed. Injuries were classified according to the on-line 11th Revision of the International Classification of Diseases method. Section 22 (Injury, poisoning or certain other consequences of external causes) was used to record the “immediate cause of death” (cause of death) and Section 23 (External causes of morbidity or mortality) was used to record the “underlying cause of death” (manner of death) for each animal. In most cases, death occurred as a result of road trauma but in some cases, abuse and voluntary killing were investigated. The recognition of non-accidental injuries is particularly important for both the defense in court of animals and for the connection between crimes committed against animals and against humans, known as “The Link”. The use of the ICD-11 method, as a sort of summary of the autopsy report, was confirmed to be of great value for the clarity and simplicity of processing the data collected also by veterinary pathologists. The veterinary pathologists can use this evidence-based method with the aim of creating a national register and therefore, to understand the real extent of the human impact on wildlife and document it in a scientific and statistically usable way

Pliocene Diatom Biomarkers in Sabrina Coast. EAIS Continental Marginal Dynamics

PNRA Tytan project, supported by the National Institute of Oceanography and Applied Geophysics (OGS), focused on the advances and retreats dynamics of the ice sheet and on variations in the glacial regime. Unit 2 focused on Diatom biomarkers and assemblages analysis on sediments of core PC03, collected during the IN2017-V01 cruise on the eastern flank of the Minang-a (or Whale) submarine Canyon. The project aims at reconstructing the depositional environment of the continental margin off the Totten Glacier and diatom data remained a key tools to constrain past ice-sheet dynamics and to forecasting future behaviour in a warming world. Preliminary dataset from diatom biostratigraphic tools allows to refer the base of the core to Pliocene while the upper part of the core records more modern EAIS dynamics, indicative of minor sedimentary evolution steps of the continental margin. Diatom assemblage analyses highlight Eocene-Oligocene reworked material and freshwater diatom inputs in Pliocene sequence, strengthening the debate about ice-sheet and paleoceanographic models, WAIS cyclic collapse and suspected Pliocene EAIS retreat into major subglacial Antarctic basins
