Authors: Nascentes Rejane , Azevedo Izabel , Jesus Simone , Neto Francisco , Tibana Sergio , Guimarães Lucas , Portelinha Fernando
Published: January 2022

No Município de Campos de Goytacazes, RJ, Brasil, a vinhaça (ou vinhoto), subproduto da produção de açúcar e álcool, tem sido utilizada nos canaviais para fertirrigar o solo. Entretanto, se por um lado essa prática favorece as lavouras no que diz respeito à qualidade e ao tempo de maturação da cana-de-açúcar, por outro pode causar a contaminação do lençol freático. Como ainda são poucas as informações sobre o po - ten cial contaminante da vinhaça, o objetivo desse trabalho é determinar, em laboratório, os coeficientes de difusão do potássio e do nitrato, presentes em altas concentrações nesse efluente, para avaliar sua mobilidade no solo de uma área de fertirrigação daquele município, tendo em vista as exigências dos órgãos ambientais. O programa experimental incluiu ensaios de caracterização do solo, análises químicas e físico-químicas e en - saios de difusão em amostras reconstituídas. Os valores determinados estão próximos daqueles encontrados na literatura, em solos argilosos.
Dinâmica urbana e riscos geo-ambientais na região metropolitana de Natal, Nordeste do Brasil
Authors: Martins Guttenberg , Filho Manoel , Freire George
Published: January 2022

A Região Metropolitana de Natal (RMN), Nordeste do Brasil, é formada por nove municípios onde habitam 1,25 milhões de pessoas. Nesta afloram terrenos sedimentares de idade cenozóica e quartenária na porção litorânea e rochas gnáissicas pré-cambrianas no interior continental. Na RMN, as reservas hídricas estão constituídas pelas lagoas de médio porte, pelas bacias hidrográficas dos rios Potengi, Ceará-Mirim e Trairí; e pelos recursos hídricos do aquífero dunas-barreiras. Neste trabalho, a expansão da área urbana nas últimas décadas foi analisada com o suporte na variação temporal de imagens LANDSAT e CBERS. Nesta análise observam-se duas tendências principais: a expansão da área urbana no entorno do Rio Potengi e na faixa litorânea. Como decorrência direta desta expansão ocorre dois tipos de riscos geo-ambientais de alta relevância, a depreciação da qualidade dos recursos hídricos subterrâneos e a interferência nos processos de erosão na linha de costa e nos complexos estuarinos.

Published: January 2022

Este estudo apresenta uma proposta metodológica, no âmbito da geo-engenharia, para a avaliação geotécnica e cartografia de estruturas de protecção costeira (esporões) na região de Espinho (NW de Portugal). Foram seguidas as recomendações e a terminologia do manual do uso de rochas em engenharia costeira (CIRIA/CUR, 1991; CIRIA et al., 2007) e a proposta de caracterização/avaliação geológico-geotécnica da ISRM (1978, 1981). Apresenta-se uma proposta de ficha geotécnica aplicada ao reconhecimento e inspecção visual dos blocos do material-rocha da estrutura e, com o recurso a imagens aéreas de alta resolução orto-rectificadas e georreferenciadas. De seguida, realizou-se uma cartografia aplicada de pormenor dos blocos rochosos que deu origem a mapas temáticos do esporão e, assim, permitiram uma avaliação segundo diferentes parâmetros geológico-geotécnicos. Apresentam-se, por fim, algumas sugestões que poderão contribuir para o planeamento de uma obra deste tipo, bem como para a caracterização do estado de conservação da estrutura e da sua evolução.
Melhoramento do desempenho de misturas de solo-cimento com recurso a activadores de baixo custo
Authors: Cruz Maria , Jalali Said
Published: January 2022

Este artigo apresenta os resultados de um trabalho de investigação realizado para avaliar os efeitos da utilização de cimento nos solos residuais graníticos, sob o ponto de vista da capacidade de carga e da durabilidade. Registaram-se as resistências à compressão simples e à tracção por compressão diametral, para avaliação das características mecânicas, enquanto que para a durabilidade, foi avaliada a absorção de água por capilaridade e a perda da resistência à compressão por saturação e devido a ciclos de molhagem- -secagem e de gelo-degelo. Para melhorar o desempenho das misturas de solo-cimento foram estudados os efeitos da utilização de activadores de baixo custo em pequenas percentagens. Os resultados demonstram que a utilização do cimento melhora o desempenho mecânico e a durabilidade dos solos residuais graníticos. Mais ainda, foi observado que alguns dos activadores estudados melhoram significativamente o desempenho mecânico das misturas, tornando-se uma vantajosa alternativa ao aumento do teor em cimento.
Lucubrações sobre modelos de equilíbrio limite de resistência de descontinuidades em maciços rochosos
Authors: Gomes Correia Manuel
Published: January 2022

Revêem-se os modelos de equilíbrio limite de resistência de descontinuidades mais importantes e a sua aplicabilidade às descontinuidades ajustadas e desajustadas. Refere-se o papel da rugosidade, a maneira de a considerar nos modelos e dadas as limitações dos modelos de equilíbrio limite de forças sugere-se um modelo de equilíbrio limite de energias. Estuda-se o efeito das tensões normais médias aplicadas na desconti nuidade (σn). Estudam-se efeitos de escala ligados ao campo de aplicação dos modelos referidos e dão-se razões para o facto de não haver tantos acidentes na vida real como seria de esperar, de cálculos de estabilidade feitos através de descrições tão precárias do fenómeno de deslizamento de descontinuidades, como os modelos de equilíbrio limite.
Confiabilidade de estacas cravadas. Estudo de caso com aplicação da teoria Bayesiana
Authors: Cabral Eduardo , Danziger Bernadete , Pacheco Marcus
Published: January 2022

O engenheiro geotécnico costuma se deparar com várias incertezas. Algumas são inerentes à variabilidade do solo, às condições de carregamento, aos efeitos do tempo, aos processos executivos, aos erros nos ensaios, que influenciam diretamente as estimativas de projeto. Neste trabalho é proposta uma adaptação a estacas em terra de um procedimento concebido para emprego em estacas “offshore”, que trata da atualiza ção da estimativa da resistência durante a cravação, com base em registros de execução. A atualização é feita pela aplicação da análise Bayesiana, assumindo que os parâmetros da distribuição probabilística utilizada se jam variáveis randômicas. A incerteza é modelada por distribuições “a priori” e “a posteriori”. A distribuição “a posteriori” é calculada pela atualização da distribuição “a priori”, utilizando uma função de máxima veros similhança, que contempla os registros de cravação. O procedimento é aplicado a um conjunto de estacas de um extenso estaqueamento executado na Zona Oeste do Rio de Janeiro.

Authors: Santos Ricardo , Laura Laura , Neves Emanuel
Published: January 2022

Neste artigo é efetuado um estudo, com base em ensaios laboratoriais, em que se simula a fase de progressão da erosão tubular em barragens de aterro. Foi utilizado o ensaio de erosão por fuga concentrada materializada através a execução de um furo (Hole Erosion Test - HET), para avaliar a erodibilidade de um solo, proveniente de alteração de maciços xisto-grauváquicos, com potencial para ser aplicado no aterro de barragens de aterro. Foram realizados 24 ensaios HET, em provetes parcialmente saturados, compactados com três energias predefinidas e com diferentes teores em água. Em particular, foi avaliada a influência das condições de compactação na erodibilidade do solo, nomeadamente, na respetiva taxa de erosão e na tensão de corte crítica. Foi observada uma influência relevante do teor em água de compactação na resistência à erosão do solo ensaiado. Foram complementarmente realizados dois ensaios HET, com molhagem prévia do solo na zona do furo, que mostraram a importância da expansibilidade do solo na progressão de erosão tubular.

Authors: Paiva Cláudia , Vendrame Íria
Published: January 2022

O presente trabalho possui como objetivo avaliar a erodibilidade de horizontes residuais perten centes à bacia do rio Una situada no município de Taubaté, no estado de São Paulo, Brasil. Dentre os fatores que contribuem para o surgimento e evolução dos processos erosivos ocasionados pela ação da água das chuvas, destaca-se a erodibilidade do solo que pode ser entendida como a maior ou menor facilidade com que as partículas de solo são desagregadas e posteriormente transportadas. Tal parâmetro é avaliado segundo os critérios da metodologia Miniatura Compactado Tropical (MCT) e pelo ensaio de Inderbitzen para quatro hori zontes residuais coletados. Os resultados mostraram que os procedimentos aplicados e os valores encontrados para o parâmetro erodibilidade são coerentes com os valores apresentados no meio técnico para solos com características e comportamento geomecânico semelhantes às amostras ensaiadas.

Published: January 2022

Uma das principais fontes de contaminação da água subterrânea é causada por vazamentos de combustíveis, contidos nos Sistemas de Armazenamento Subterrâneo de Combustíveis dos postos de revenda. Na presente pesquisa será abordado um estudo de caso sobre contaminação do lençol freático pelo vazamento de derivados de hidrocarbonetos ocorrido na região metropolitana de Belém, Pará (2008). Primeiramente foi aplicado um questionário para levantamento de dados com a comunidade local, com o intuito de verificarmos os fatores que afetaram a vida dos moradores após a contaminação; posteriormente, com um levantamento geofísico realizado nas imediações do posto, na Rua Hélio Pinheiro próximo a rodovia Augusto Montenegro, na cidade de Belém, PA, foram utilizadas as seguintes metodologias: 1) Método geofísico GPR (Radar de Penetração no Solo), na intenção de detectarmos o deslocamento da pluma de contaminação e a presença de uma assinatura eletromagnética distinta. 2) A análise bacteriológica, no total de doze amostras, indicando a presença de benzeno, tolueno, etilbenzeno e xileno confirmando e ratificando a presença de contaminantes e o possível grau de contaminação.
Considerações sobre um modelo de equilíbrio limite de energias de deformação para diáclases
Authors: Gomes Manuel , Carlos Carlos , Pinto Amândio
Published: January 2022

Os modelos de equilíbrio limite de forças para descontinuidades em maciços rochosos têm o grave óbice de não permitirem a integração da amplitude da rugosidade, pois apenas consideram parâmetros adimensionais relacionados com a geometria das asperezas. Ora, para uma caracterização adequada da rugo sidade é essencial considerar também a sua amplitude. Daí a formulação do modelo de equilíbrio limite de energias de deformação para as diáclases que se propõe, pois nos modelos correntes de equilíbrio limite de forças duas diferentes descontinuidades em que a rugosidade tem a mesma inclinação mas diferentes am plitudes, deslizam para a mesma força tangencial, quando na verdade têm diferentes resistências. Apesar de alguns fatores de imprecisão das estimativas das energias de deformação (como o valor da libertação de calor nos processos, plastificações, etc.) não estarem devidamente investigados, as formulações sugeridas mostram pertinência e verosimilhança encorajadoras principalmente para cálculos envolvendo amostras de grande área.
Verified Integration of Differential Equations with Discrete Delay
Authors: Rauh Andreas , Auer Ekaterina
Published: January 2022

Many dynamic system models in population dynamics, physics and control involve temporally delayed state information in such a way that the evolution of future state trajectories depends not only on the current state as the initial condition but also on some previous state. In technical systems, such phenomena result, for example, from mass transport of incompressible fluids through finitely long pipelines, the transport of combustible material such as coal in power plants via conveyor belts, or information processing delays. Under the assumption of continuous dynamics, the corresponding delays can be treated either as constant and fixed, as uncertain but bounded and fixed, or even as state-dependent. In this paper, we restrict the discussion to the first two classes and provide suggestions on how interval-based verified approaches to solving ordinary differential equations can be extended to encompass such delay differential equations. Three close-to-life examples illustrate the theory.
Diagnostic Efficacy of Clinical Diagnosis, Histopathological Diagnosis as Compared to Direct Immunofluorescence in Autoimmune Blistering Diseases - A Study from South Kerala
Authors: Bagde Pranaya Ashwanikumar , Sunny Beena , Mathew Rani
Published: January 2022

BACKGROUND Autoimmune blistering diseases contribute to a significant number of patients attending the dermatology department. As they have a varied presentation, definite clinical diagnosis is not possible always. Histopathology is also inconclusive sometimes. Immunofluorescence studies are now considered to be most valid in diagnosing these problems. Direct immunofluorescence study of perilesional skin will help us to identify the type of immunoreactants and their exact site of location. This may help dermatologist to make accurate and prompt diagnosis. Hence we decided to conduct this study. METHODS We conducted a diagnostic tool evaluation cross sectional study in 34 patients, who attended dermatology outpatient department (OPD) of a major tertiary care centre in South Kerala, with a clinical diagnosis of immunobullous disease. We performed histopathology and direct immunofluorescence (DIF) in all our patients. RESULTS Age group of study population ranged from 31 – 90 years with a definite female preponderance. 32.4 % of our patients had intraepidermal immunobullous diseases while rest had subepidermal disorders. Pemphigus vulgaris was the commonest intraepidermal disease reported, with most patients presenting in fifth and sixth decade. Oral erosions were the presenting symptom in 97.5 % patients. Classical histopathology was seen in all except one, clinicopathological correlation being 87.5 %. Pemphigus erythematosus could be diagnosed only by DIF. Direct immunofluorescence had 100 % negative predictive value (NPV). Among subepidermal immunobullous diseases, bullous pemphigoid was seen in 19 patients with age ranging from 41 - 90 years. Clinical, histopathological and DIF correlation in bullous pemphigoid was 100 %. Clinical diagnosis of lichen planus pemphigoids and bullous systemic lupus erythematosus could be confirmed by histopathology and DIF while linear IgA disease showed features of bullous pemphigoid in DIF. Positive and negative predictive value reached 100 % in the present study. CONCLUSIONS Direct immunofluorescence study is a useful investigation for the correct diagnosis of various immunobullous diseases although histopathology is more relevant in diagnosis of certain subtypes of pemphigus. KEY WORDS Immunobullous Diseases, Direct Immunofluorescence, Histopathology.
A Study of the Functional Outcome of Galeazzi Fractures Treated with Open Reduction and Internal Fixation in Government Medical College Thrissur, Kerala
Authors: Pillai Abhilash , C.V Krishna Kumar
Published: January 2022

BACKGROUND In a Galeazzi fracture, a distal radius shaft fracture is accompanied by a disruption of the distal radio ulnar joint (DRUJ). 3 % of all forearm fractures in children and 7 % of forearm fractures in adults are Galeazzi fractures. These may be due to direct or indirect trauma to the wrist. Mechanism of injury of a Galeazzi fracture is either due to a force applied onto the dorsolateral aspect of the forearm, or a fall on the outstretched hand with the forearm in pronation. In adults, Galeazzi fractures are treated by open reduction and compression plating of the radius and stabilization of the ulna if needed. We designed and carried out this study to find out the influence of the various factors associated with the fracture, its treatment and to find out which of these influenced the outcome. METHODS A prospective study was carried out in the Dept. of Orthopaedics, Government Medical College, Thrissur. All Galeazzi fractures presenting to the Orthopaedics Out Patient or Casualty during the study period were evaluated. RESULTS Post-operative rehabilitation is pivotal for ensuring an excellent functional outcome. Of all the parameters which were taken into account in the study, the only ones which made a difference was the period of immobilization in plaster cast given. Early mobilization yielded better functional result. CONCLUSIONS 25 cases Galeazzi fractures treated by open reduction done in our institution were followed up till union. The results were assessed with reference to the various parameters affecting fracture healing. Of all the factors which were considered, only the timing of removal of plaster and the physiotherapy given made any difference in the final functional result.

VERIFICATION OF THE BEARING CAPACITY OF PILES
Authors: Turček Peter , Súľovská Monika
Published: January 2022

The location of the buses in the basement of the new bus station in Bratislava, supplemented by two further parking floors below, shifted the foundation joint of the new bus station to a depth of approximately 14 m. The maneuvering space for the buses required unusually large distances between the supporting columns. In extreme cases, it was necessary to transfer a vertical load of more than 30,000 kN from the column to the subsoil. Only a relatively thin layer of Quaternary gravel remained between the footing bottom and the Neogene soils. The whole area was designed to be based on deep foundations. As this was a construction of the 3rd geotechnical category, it was necessary to verify the bearing capacity and quality of the piles. The applied test methods (especially the dynamic load tests) confirmed the correct design and implementation of piles.

The state forest existence is expected to provide maximum benefits for the people's prosperity. This study identified the forest state existence through a land tenure structure in Segah District Berau Regency East Kalimantan Province. It also described a portrait of rural development including the condition of infrastructure and community income/expenditure, and identified the influence of state forest existence on rural development. The methods used to analyze the structure of land tenure by overlaying land cover maps and boundaries of area functions in each village, then classifying villages using a matrix of plots based on the percentage of forest and forest area. Analysis of rural development was carried out using scalogram analysis and oneway ANOVA. Meanwhile, the analysis of the influence of state forest existence on rural development was carried out using descriptive analysis and multiple linear regression. The results of this study showed that the land cover of the forest and land tenure of forest area were dominant. This means that the land tenure structure in the administrative area of Segah District was dominated by state forest. Rural development in terms of infrastructure was found in a condition that was quite even lacking of the needs of the rural population, while average household expenditure is above the national average minimum expenditure limit. The state forest existence was indicated to have a role in influencing the development of rural infrastructure and household expenditure, especially in the activity of entering the forest which can reduce the expenditure of primary household needs.

Objective — to study the effectiveness of topical application of standardized fermented papaya gel (SFPG) in the complex therapy of moderate chronic periodontitis developed as an orthodontic treatment complication. Material and Methods — Our study involved 50 patients with periodontitis of a moderate severity developed against the background of a treatment with a fixed orthodontic appliance. Periodontitis has developed as a long-term consequence of the fixed orthodontic appliance. Orthodontic treatment of patients was carried out with metal ligature braces. The patients were divided into two groups: Group 1 with conventional periodontitis treatment supplemented by SFPG applications on the gums for 15 minutes daily during 14 days; Group 2 with conventional treatment alone. The concentration of proinflammatory and anti-inflammatory cytokines in periodontal pockets was determined using solid-phase type of enzyme immunoassay (Vector-Best test system, Russia). The nitrite/nitrate content in the periodontal pocket fluid was determined spectrophotometrically using the Griess reagent kit, following the manufacturer’s instructions (Sigma-Aldrich, USA). Results — Patients receiving SFGP exhibited a reduction in inflammation, manifested in decreased gum bleeding, swelling, hyperemia, and exudate from periodontal pockets. We observed the restoration of the balance of proinflammatory cytokines (IL-1β, IL-6) and anti-inflammatory interleukin (IL-10), and reduction in the nitrite/nitrate content. Conclusion — Clinical effectiveness of the therapy with natural fermented herbal preparations may be associated with its antioxidant and antimicrobial properties.

Authors: Belimova Lyudmila N. , Balyazin Viktor A.
Published: January 2022

Objective: assessing pharmacopuncture effect on pain syndrome and level of anxiety-depressive disorders in patients with chronic tension-type headache (CTTH).
Materials and methods. An open-label controlled trial was conducted on 95 CTTH patients split among two groups by means of adaptive randomization. The comparison group subjects were receiving 35-70 mg/day of amitriptyline and 450 mg/day of tolperisone, while patients of the treatment group were assigned 2-4 courses of pharmacopuncture by the original method. The results were evaluated on the basis of the scores obtained via Visual Analogue Scale (VAS), McGill Pain Questionnaire, Beck Depression Inventory (BDI), and State-Trait Anxiety Inventory (STAI) sensu Ch. Spielberger and Yu. Khanin.
Results. Patients in both clinical groups were inclined to a positive evaluation of received treatment. Based on the results of McGill Pain Questionnaire, we determined both affective and sensory pain descriptors, with a predominance of the latter. Both groups exhibited moderate depressive symptoms according to BDI of the psychological status. Prevalence of trait anxiety over reactive anxiety was determined by STAI. According to VAS, pain intensity after the treatment declined from 5.26±0.87 to 1.7±0.78 points (p<0.05) and from 5.17±0.78 to 1.65±0.79 (p<0.05) in the comparison group versus the treatment group. An improvement of anxiety and depression indicators was detected.
Conclusion. Our results have demonstrated that pharmacopuncture is very promising in treating CTTH patients
Urban Planning, Public Health and Urban Climatology Through History
Authors: Lavtižar Kristjan
Published: January 2022

It is a well-established fact in the profession of climatologists that anthropological procedures in an urban landscape create a region-specific climate. This was followed by the realization that urban planning is an important variable as well. While this is already known, today this issue is often not addressed in practice and does not affect the very process of urban planning, urban design or other disciplines dealing with spatial planning. The article includes an overview of the history of urban planning to try to determine when and in what context of urban climatology and public health have interventions in space been planned in the past. The scope of research includes a review of literary material with addressing some exceptional cases of spatial planning in practice that were characteristic of individual periods in architecture and urbanism. The aim of the study is also to investigate the reasons why the urban planners of the past have used climate studies the process of spatial design. Are there special reasons that led to the emergence of some plans, that we perceive differently or incompletely today, without understanding the important social background? The central part of the paper presents some key conclusions that deal with individual climatological starting points, which are common to the relevant urban theorists and reference projects cited.
Hospital Navigation: Spatial Configuration and Spatial Cognition in University Clinical Center of Kosovo in Prishtina
Authors: Meka Bardha , Ferati Armir
Published: January 2022

The aim if this paper is to analyse the level of ease at which people navigate within the University Clinical Centre of Kosovo in Prishtina (UCCK). In a hospital setting, the objective for the user is to navigate easily and independently to the destination in order to reduce negative impacts on human wellbeing and operational costs. Navigation is important for employees, familiar with the environment and for visitors, unfamiliar with it. However, the paper is focused only on those familiar with the hospital setting – employees. Research has shown that navigation depends on the clarity of the built form’s component arrangements; that there is a high correlation between navigation and spatial configuration. Most of the studies on navigation in hospitals are focused on building scale. This paper is focused on the hospital campus of (UCCK) which belongs to the pavilion typology. As such, it shares many similarities with cities and has far more complex structure than other hospital typologies. So, the questions this paper is trying to answer are: how easy is to navigate within UCCK; what is the relation between spatial cognition and spatial configuration in the hospital setting? To answer, the research is leaning on the cognitive approach designed by K. Lynch based on mental maps and on the configurational approach based on space syntax theory and methodology. The paper reveals that UCCK lacks a clear image and has a low level of intelligibility. The outcome of this research should impact the future master plan of the hospital campus.

The purposes of this study are 1) to identify the environmental literacy of the students and the school community in the green open space 2) to identify the difference between students’ environmental literacy and school community in green open space. The sample consists of 70 students and 40 people from the school community. Measurement of environmental literacy is discussed in 3 domains, namely the domain of knowledge, attitudes towards the environment, and behavior towards the environment. The total number of instruments is 45 items. The reliability value of instruments for knowledge, attitude, and behavior domains are 0.874, 0.927, and 0.965, respectively, and are the high category. Collected data of students and school community were analyzed by using Microsoft Excel and SPSS. The difference in environmental literacy of students and school community in green open space was analyzed by using Mann-Whitney U Test. The environmental literacy value of students and school community are respectively 77.1% and 79.7% and are high category. The analysis on the achievement of environmental literacy scores shows that there are no significant differences in both groups. This concludes that the school community that has good environmental literacy will give a good influence on students’ environmental literacy and knowledge. The last, by knowing the roles of the school community and availability of green open space on achieving environmental literacy of students, all related stakeholders are suggested to upgrade the environmental literacy of the school community and support the availability of green open space in the school area.

Published: January 2022

This article is the result of a two-year-long experiment conducted by the authors. The purpose of the research was to study the natural scientific thinking of foreign students of preparatory departments in the context of integrative processes. The quantitative and qualitative analysis of the regulatory framework governing the educational process at the stage of pre-university training, including syllabi and steering documents of faculties of pre-university training, formed the methodological basis of the research. The modified criteria-focused TEM-11 test was used as a diagnostic tool. The method of expert evaluations ensured the reliability and validity of the research. The study provided evidence of the feasibility of including an integration course in “biophysics” along with biology, physics, and chemistry in the curricula of preparatory departments that prepare foreign students for admission to medical, agricultural, veterinary, and biological faculties. It does not appear reasonable to include an online course in the training system for foreign students who are residents since they already developed the differential-synthetic and synthetic stages of natural scientific thinking while they were learning the trade. It is concluded that the Biophysics integrative online course studied by foreign students of faculties of pre-university training, develops a special type of natural scientific thinking, which will be the basis for framing professional thinking in the future. A total of 374 people took part in the experiment (188 people were included in the experimental group and 186 people became part of the control group). The comparative analysis of the stages of development of natural scientific thinking in the control and experimental groups showed significant progress in the experimental group. After the experiment, the number of respondents at the common empirical stage of development of natural scientific thinking was 11.2 % of the entire sample; the number of respondents at the scientific empirical stage was 32.8 %, at the synthetic differential stage – 44.7 % and at the synthetic stage – 27.6 %.

Perfil mineral de los alimentos importados para mascotas en Costa Rica
Authors: Cedeño-López André , WingChing-Jones Rodolfo
Published: January 2022

Introducción. El contenido mineral de los alimentos para mascotas no siempre está presente en la etiqueta. Es importante conocer esta información para valorar el aporte nutricional del alimento. Objetivo. Determinar el contenido de Ca, P, K, Na, Mg, S, Cu, I, Fe, Mn y Zn en 34 alimentos importados para perros, gatos, conejos, hámsters, peces ornamentales y tortugas, y comparar los resultados con las recomendaciones encontradas en la literatura. Materiales y métodos. Durante los meses de agosto y diciembre del año 2018, se obtuvieron diez muestras de alimentos para perros y gatos, cinco para peces ornamentales, cuatro para tortugas, tres para hámster y dos para conejos. Estas se adquirieron de manera directa en diferentes puntos de venta en la Gran Área Metropolitana, San José, Costa Rica. Las muestras se analizaron en el Centro de Investigación en Nutrición Animal de la Universidad de Costa Rica. Se cuantificaron los minerales Ca, P, K, Mg, S, Cu, I, Fe, Mn, y Zn con base en la metodología recomendada por la Association of Official Analytical Chemists. Se calculó el contenido promedio por grupo de alimento según la especie animal, la desviación estándar, valores máximo y mínimo; se comparó con las recomendaciones nutricionales para minerales encontradas en la literatura. Resultados. Los alimentos estudiados cumplieron, en promedio, con los requerimientos minerales de los animales de compañía. Se observaron desbalances en el contenido de Ca, P y Mg para el caso de alimentos para tortugas, altos contenidos de yodo en alimentos para perros y relaciones desbalanceadas entre minerales. Conclusiones. Se generó una base de datos con valores promedios y su dispersión en once minerales en 34 muestras de alimentos comerciales de siete animales de compañía en Costa Rica. Se observó la poca información sobre límites superiores recomendados y requerimientos en especies como hámster, peces ornamentales o tortugas.
Experimental, Acquisitional and Corpus linguistic Approaches to the Study of Morphonotactics
Authors: Dressler Wolfgang U. , Calderone Basilio , Sommer-Lolei Sabine , Korecky-Kröll Katharina
Published: January 2022

This volume unites six contributions on morphonotactics of consonant clusters and its difference to phonotactics (in a narrow sense). Morphonotactics comprises that part of phonotactics (in the large sense) which is due to interaction with morphology. It deals prototypically with clusters which are due to morphological concatenation as in the word-final consonant cluster in Ger. (er/sie) mach-t '(he/she) make-s', which is morphonotactic vs. its phonotactic homophonous equivalent Macht 'power'. The opening chapter introduces into the area of morphonotactics and into the following five chapters which deal with German or French morphonotactics or both. The first represents the first corpuslinguistic analysis of German morphonotactics based on a large electronic corpus, the second investigates phonetic processing in both languages, the remaining three, equally distributed between both languages, with the impact of (mor)phonotactics on processing and language acquisition. Thus, this volume unites phonological, morphological, phonetic, psycholinguistic, corpuslinguistic and typological perspectives integrated into a series of experimental approaches. The volume publishes selectively results of a bilateral research project funded by the Agence Nationale de la Recherche (ANR) and the Austrian Science Fund (FWF).

Authors: Rego Marcos Lopez , Irigaray Hélio Reis Arthur
Published: January 2022

Resumo O objetivo deste ensaio é analisar a estrutura e a operação da gestão pública no Reino Unido de Portugal, Brasil e Algarves, relacionadas à indústria extrativista de diamantes por meio das obras de Saint-Hilaire, botânico e naturalista francês, que visitou e percorreu o Brasil no século XIX, em viagem realizada em 1817. O autor descreveu aspectos ligados à estrutura organizacional, aos processos da operação de extração de diamantes, aos métodos de gestão pública, de recursos humanos, financeira e contratos no distrito dos diamantes. A análise de seus relatos revelou o alto grau de controle, bem como as condições de trabalho dos escravos e a rígida estratificação social do Brasil Império, com intensa utilização de mão de obra escrava, por meio do que se chamava à época de aluguel. Conclui-se que o autor fez extenso relato da operação, com inestimável contribuição para os estudos dos primórdios do Estado brasileiro.

Authors: Secchi Leonardo , Wink Junior Marcos Vinicio , Moraes Cryslan Jorjan de
Published: January 2022

Resumo O artigo busca analisar o desempenho do financiamento coletivo (crowdfunding) como estratégia de arrecadação de recursos para a campanha eleitoral a deputado federal nas eleições de 2018. Também foi analisada a influência de características socioeconômicas e demográficas dos candidatos associada à decisão de adoção do financiamento coletivo como alternativa arrecadatória na campanha eleitoral. A metodologia utilizada foi a de regressão logística, considerando as seguintes variáveis independentes: valores arrecadados, escolaridade, idade, raça e estado civil do candidato, além de ideologia, tamanho e antiguidade do partido. As variáveis dependentes binárias foram: utilização ou não do crowdfunding e sucesso ou insucesso eleitoral. A fonte de dados foi o repositório de dados eleitorais do Tribunal Superior Eleitoral (TSE), com informações de todos os candidatos a deputado federal, de todos os estados brasileiros, no pleito de 2018. Entre os resultados obtidos, encontra-se que o crowdfunding foi estatisticamente mais usado por candidatos brancos, jovens, de alta escolaridade e da região Sul. Há evidências também de que o crowdfunding seja uma estratégia eleitoral utilizada sobretudo por candidatos de partidos de criação recente, de esquerda, centro-esquerda ou de direita - os de centro e centro-direita tiveram menor utilização -, e daqueles com maior bancada. Por fim, o modelo econométrico aponta um acréscimo médio de 5,55 pontos percentuais na probabilidade de sucesso eleitoral dos candidatos que se valeram do crowdfunding.
