Повний текст джерелаThe aim of the thesis is to identify the influence of various factors on blood indices and breathing function of the Black sea dolphins (Tursiops truncatus ponticus) that are kept in dolphinariums and also to do analysis of the reasons of dolphins’ diseases and death. The goals of the thesis: 1. Determine the physiological morphological and biochemical parameters of the dolphins’ blood with regard to their age and sex. 2. Determine the influence of the size of the pools on the respiratory rate of dolphin females and calves during the postnatal period. 3. Analyze the diseases affecting dolphins and the frequency of their occurance. 4. Study morphological and biochemical changes in dolphins blood parameters with regard to the diseases. 5. Identify the causes of death through pathological, anatomical, histopathological and microbiological examinations. The research has broadened the scientific knowledge about the Black sea dolphins’ (Tursiops truncatus ponticus) physiological characteristics and pathological conditions. It has been found out that the size of a pool has influence over the Black sea dolphin females and calves' respiratory rate as well as behaviour. Bearing in mind that there are genetic differences among other Tursiops truncatus dolphins, in the current research healthy Black sea afalins’ blood physiological morphological and biochemical parameters have been identified with regard to their age and sex. It is the first time in Lithuania when the frequencies of... [to full text]

Повний текст джерелаIn this research was developed tool, which helps to determine, which morphological mark attributes are important when solving problem of morphological ambiguity in Lithuanian language. Morphological ambiguity problem is solved, when one word is matched with one morphological mark. Research uses corpus, which contains over than 1.200.000 words. Morphological marks in the corpus were assigned by expert and list of all possible morphological marks was generated with other utility. There was developed and applied Viterbi algorithm to solve morphological ambiguity problem, which finds the most expected path of part of speeches by created bigram or trigram speech models. Testing was implemented using cross validation with 10 folds. There was achieved these results: • 90,10% – accuracy, which shows if morphological mark was correctly match with ambiguous word; • 96,39% – total accuracy, which calculated when included non-ambiguous words.

Повний текст джерелаLa tesi di dottorato presentata è stata concepita nell’ambito di un più ampio progetto che comprende molteplici studi tra loro intrinsecamente correlati. L’obiettivo principale del lavoro consiste nella descrizione delle basi teoriche, sviluppo nonchè applicazione pratica nel campo della diagnostica per immagine e chirurgia di un nuovo protocollo 3D utilizzato per la misurazione di angoli nel femore del cane. Lo scopo successivo è stato quello di descrivere il valore traslazionale della procedura analitica qui presentata. Il primo passo dell’intera ricerca è rappresentato dalla validazione della metodologia. Un nuovo algoritmo sviluppato consente, per mezzo di un CAD software di comune utilizzo (Rhinoceros), di eseguire la computazione di angoli in 3D. Il secondo step ha previsto la verifica della ripetibilità e della riproducibilità di tale metodica che è stata comparata con quelle più comuni effettuate con radiografia e Tac. Infine, con l’ultimo studio abbiamo traslato le basi teoriche in applicazione chirurgica andando a creare, per mezzo dell’algoritmo elaborato, delle dime chirurgiche. Questi strumenti intra-operatori sono molto utili durante la chirurgia per le osteotomie correttive in quanto si accoppiano perfettamente nel punto di deformità e consentono di guidare l’osteotomia dell’osso.

Повний текст джерелаThe Itapocú coastal barrier is located in the northern coast of Santa Catarina State, on the domain of Barra Velha and Araquari cities. In its central part the barrier is segmented due to the influence of the Itapocú river mouth. Historical records demonstrate that the barrier experiments frequent overwash events. The barrier and associated environments were mapped for 1938, 1957, 1978, 2005 and 2012 dates. Additionally, three vulnerability indexes to the washover deposits were applied, according to Garcia et al. (2010) – OSR, MOIR and CBO, and the granulometric properties were analyzed for the modern beach-dune system and washover deposits in two cross sections. The morphological analysis showed that the main changes observed were related to inlet migration, before its fixation in 2011, and also to overwash events. The washover deposits showed high frequency of occurrence along the barrier (OSR), with the greater occurring in 1957, reaching 42% of its entire length in the south, and 60% in the north section. This pattern presented a decrease behavior over time, and in 2012 approximately 1% of the barrier length was overwashed in the south section and 19% in the north. The index MOIR, related to historical sediment intrusions of overwash processes, and representing a maximum intrusion was applied in 10m intervals and showed that washover events tend to occur in all years in the ICB, reaching 40m of intrusion. For the last year analyzed, 2012, the CBO index showed 3 situations of maximum intrusion, indicating 100% of barrier breaching vulnerability. In the comparative granulometric study, it was not possible to characterize the environmental deposits based on the granulometric parameters. However, non-discretize pattern can indicate the influence of coastal marine processes (overwash) acting over the eolian deposits.

Resumo: O silício é considerado, para o arroz e a cana-de-açúcar, um elemento de relevada importância, pois, em muitas situações, tem proporcionado maiores tolerâncias a estresses bióticos e abióticos. No entanto, em muitas situações não tem sido constatado efeito positivo do silício, o que pode estar relacionado a fatores genéticos quanto à capacidade em adquirir silício em baixa disponibilidade e/ou utilizar o elemento absorvido com maior eficiência. Os mecanismos de absorção presentes na interface solo-raiz são influenciados por eficiência fisiológica e pela morfologia radicular das plantas, representada pelo comprimento, superfície e diâmetro das raízes. Assim, o presente trabalho teve por objetivo, mediante o acompanhamento da cinética de absorção de Si (Vmax, Km e Cmin), encontrar respostas entre cultivares de cana-de-açúcar e de arroz quanto à capacidade de absorção e utilização do silício, quando submetidas a condições distintas de disponibilidade e carência do elemento, procurando relacioná-las a parâmetros fisiológicos de absorção, parâmetros morfológicos de raízes e eficiência de utilização deste mineral. Foram realizados dois experimentos independentes, um para a cana-de-açúcar e outro para o arroz, em casa de vegetação, na Faculdade de Ciências Agronômicas/UNESP, em Botucatu-SP.

Abstract: Silicon is considered of great importance for sugar cane and rice because it can improve tolerance to biotic and abiotic stress. However, silicon has not shown positive effects in many situations probably due to genetic factors related to capacity of plants to absorb this element in lower availability or/and efficiently use it. Uptake mechanisms found in root-soil interface are influenced by physiological efficiency and aspects of root morphology such as length, surface and diameter. Therefore, this research had the objective of monitoring Si uptake kinetics (Vmax, Km and Cmin) and identifying responses among sugar cane varieties and rice cultivars related to plant capacity of Si uptake and use under distinct conditions of availability and deficiency, associating them to physiological aspects of absorption, root morphology parameters and use efficiency. Two greenhouse experiments were separately carried out for sugar cane and rice in the College of Agricultural Sciences, UNESP, Botucatu-SP, Brazil. The experimental design for each crop was the completely randomized with six replications, analyzed as a factorial that consisted of two rice cultivars (1- high accumulation: 'Caiapó' and 2- low accumulation: 'Maravilha') and sugar cane varieties (1- high accumulation: RB85-5035 and 2- low accumulation: SP81-3250) with distinct silicon accumulation capacity and two silicon levels (sufficient: 1.7 mmol L-1 and insufficient: 0.1 mmol L-1). Kinetic parameters (Vmax, Km and Cmin), root morphology aspects (length, diameter and surface), dry matter, silicon accumulation and level in shoot and root, uptake efficiency, use efficiency and root/shoot ratio were evaluated for sugar cane and rice. Data was submitted to variance analysis and means were compared by the LSD test at a probability level of 5%. The higher silicon concentration in the nutrient solution did not increase neither sugar... (Complete abstract click electronic access below)

Повний текст джерелаBiomedical imaging represents an important topic in the field of diagnosis and clinical research. Image analysis and processing software also helps to automatically identify what might not be apparent to the human eye. The technological development and the use of different imaging modalities create more challenges, as the need to analyse a significant volume of images so that high quality information can be produced for disease diagnosis, treatment and monitoring, in clinical structures as well as at home. All the measurement systems routinely used in clinical environment require to be put in di-rect contact with the subject, which in some cases can be uncomfortable or even non-suited for long monitoring. On the other hand, in some cases contact could alter shape or composition of the samples under study, and state-of-the-art techniques could require a lot of time and provide very low resolution. This doctoral thesis presents a series of new experimental applications of the image analysis and processing in the biomedical field. The aim was to develop and validate new method-ologies, based on image analysis, for non contact measurement of quantities of different nature. The study is focused on the extraction of morphological characteristics of cell ag-gregates to assess of the regeneration processes in infarcted hearts, the design of a non con-tact methodology to measure mechanical properties of rabbit patellar tendons subjected to tensile tests, the development of new methods for the monitoring of physiological parame-ters (heart and respiration rate, chest volume variations) through the use of image acquisi-tion systems, as Kinect™ device and a digital camera. The experimental setups, designed in this work, were validated, showing high correlation respect to the reference methods. Imaging systems, although so different in many aspects, have demonstrated to be suitable for the respective tasks, confirming the feasibility of the imaging approach in the biomedical field.

The last phase of seedling production, the hardening is a technique used in nurseries which aims to expose the seedlings to more severe conditions than those submitted in the growth phase, in order to prepare them for the field. Based on the above, the aim of the present study was to evaluate the effect of the application of ethylene and bending stem in two native forest species (at different times) Cordia trichotoma and Guazuma ulmifolia. The treatments consisted in the application of stem pushups 0, 10, 20 and 40 daily crunches and sprays (0 to 4) with ethylene in a factorial design in two native species. Thus, this study was subdivided into three parts. In the first part were evaluated morphological parameters of the seedlings and their survival. The variables were height of the aerial part of the plant, stem diameter, number of leaves, SPAD index and dry mass of seedlings. In the second part, we evaluated the concentration of soluble carbohydrates in leaves, cell damage through the loss of root electrolytes and the lignin content in stems of both species. In the third part evaluated the concentration of macronutrients N, P, K, Ca and Mg. The evaluated morphological parameters was found that the G.ulmifolia species decreased in the increase in height of more than 60% and 35% in diameter collect when subjected to bending stem compared to control seedlings. The most significant results occurred with 20 pushups shoot. C. trichotoma a significant decrease in the increase in height, and the application of these factors together decreased the survival of the species. In physiological parameters G. ulmifolia species showed a linear reduction in the lignin content and increased loss of electrolytes root (REL) when subjected to bending. The concentration of carbohydrates increased by 55% when combined with stem bending factors and spraying with ethylene. The species C. trichotoma there was a reduction in the concentration of lignin, REL and carbohydrates (with the application of stem crunches and spraying with ethylene). Concerning macronutrients, it was found to be reduced to N concentration (13.2%) and P (20%) in G. ulmifolia stems, while K increased with up to 23 ethylene flexing when applied. The concentration of Ca and Mg showed an increase with 26 pushups shoot. Since the application ethylene concentration decreased by 21.6% and 14% for calcium and magnesium G. ulmifolia respectively. The species C. trichotoma revealed a linear increase in the concentration of N in stems of seedlings mechanically stimulated and sprayed with ethylene. In roots, the increase was 45% flexed 10 times a day with ethylene seedlings application. The calcium content was reduced in the stems and roots when compared to control seedlings in both treatments stem and ethylene flexing C. trichotoma. The magnesium concentration was high in no spray seedlings with ethylene until stem 25 flexing while plants sprayed linearly reduced Mg concentration is increased as the stem flexing in said species
A última fase da produção de mudas, a rustificação, é uma técnica adotada em viveiros que visa expor as mudas a condições mais severas que aquelas submetidas na fase de crescimento, com o objetivo de prepará-las para o campo. Com base no exposto, objetivou-se no presente trabalho avaliar, o efeito da aplicação de etileno e flexão caulinar em duas espécies florestais nativas (em épocas distintas) Cordia trichotoma e Guazuma ulmifolia. Os tratamentos consistiram na aplicação de flexões caulinares de 0, 10, 20 e 40 flexões diárias e pulverizações (0 e 4) com etileno em esquema fatorial em duas espécies florestais nativas. Assim, subdividiu-se este trabalho em três partes. Na primeira parte, avaliaram-se parâmetros morfológicos das mudas e sua sobrevivência. As variáveis analisadas foram: altura da parte aérea do vegetal, diâmetro de colo, número de folhas, índice SPAD e massa seca das mudas. Na segunda parte, avaliou-se a concentração de carboidratos solúveis totais em folhas, o dano celular através da perda de eletrólitos radiculares e a concentração de lignina em caules de ambas as espécies. Na terceira parte, avaliou-se a concentração dos macronutrientes N, P, K, Ca e Mg. Nos parâmetros morfológicos avaliados constatou-se que a espécie G.ulmifolia apresentou redução no incremento em altura superior a 60 % e 35 % no diâmetro de coleto quando submetida à flexão caulinar comparado a mudas controle. Os resultados mais expressivos ocorreram com 20 flexões caulinares. Em C. trichotoma ocorreu uma diminuição significativa no incremento em altura, e a aplicação destes fatores em conjunto diminuiu a sobrevivência da espécie. Nos parâmetros fisiológicos a espécie G. ulmifolia apresentou uma redução linear na concentração de lignina e aumento na perda de eletrólitos radiculares (PER) quando submetida a flexões. A concentração de carboidratos aumentou em 55% quando associado a fatores flexão caulinar e pulverização com etileno. Na espécie C. trichotoma houve redução na concentração de lignina, PER e carboidratos (com a aplicação de flexões caulinares e pulverizações com etileno). Quanto aos macronutrientes, verificou-se que foi reduzida a concentração de N (13,2 %) e P (20 %) em caules de G. ulmifolia, enquanto o K aumentou com até 23 flexões quando aplicado o etileno. A concentração de Ca e Mg mostrou um acréscimo com 26 flexões caulinares. Já a aplicação de etileno diminuiu a concentração em 21,6 % e 14 % para cálcio e magnésio G. ulmifolia respectivamente. A espécie C. trichotoma revelou um aumento linear na concentração de N em caules em mudas estimuladas mecanicamente e pulverizadas com etileno. Em raízes, esse aumento foi de 45 % em mudas flexionadas 10 vezes ao dia com aplicação de etileno. O teor de cálcio foi reduzido em caules e raízes quando comparadas à mudas controle em ambos os tratamentos com flexões caulinares e etileno em C. trichotoma. A concentração de magnésio foi elevada em mudas sem pulverização com etileno em até 25 flexões caulinares, enquanto, mudas pulverizadas reduziram linearmente a concentração de Mg a medida que se elevaram as flexões caulinares na referida espécie

Повний текст джерелаThis work is devoted to understand the effect of the formulation and more specifically of the precipitated silica on the resistivity of the PE-separators. The PE-separators are designed for the lead-acid batteries. PE-separators are composed of precipitated silica, ultrahigh molecular weight polyethylene (UHMW-PE) and organic oil. The first part of this work was to elaborate PE-separator models at a laboratory scale. Then, the factors impacting the structural and physico-chemicals properties of PE-separators were investigated. These factors are mainly the amounts of oil, precipitated silica, the grade of the precipitated silica, the temperature conditions of crystallization and the device used to elaborate the membrane. The influence of the amounts of oil and precipitated silica on the crystallization of the polyethylene wasthoroughly described showing that the oil helps to increase the final crystallinity of UHMWPE and that the silica plays a role of oil reservoir. Moreover, it was shown that the amount and the grade of precipitated silica have an influence on the wettable part of the porosity of the PE-separators. The coating of the pores by the precipitated silica is responsible of the wettability of the membranes by the electrolyte. Thus, an empirical parameter has been proposed in order to quantify the efficiency of the dispersion and distribution of the precipitated silica in the membrane. The more the membranes are wettable by the electrolyte the more the resistivity of the membranes is decreased.

The potential use of native herbaceous legumes from the Northeast of Brazil as forage are large, among them the genus Stylosanthes spp. is highlighted for its adaptability to the semiarid conditions and for its high nutritive value. This research aimed to identify morphological differences among genotypes and to estimate genetic parameters, also identify characteristics correlated with high production of dry matter with the degree of reliability in the genotypic discrimination above 80% in plants of the Stylosanthes spp. genus. Two trials were made, the first one was developed in the Universidade Federal Rural de Pernambuco (UFRPE), in the experimental field from the Academic Unit of Serra Talhada (UAST). Were used morphological descriptors to help in the identification of the differences among thirteen accessions of Stylosanthes spp. from the germplasm bank from UAST, these were collected in different areas from the semiarid. In the analyses of main components, was verified that plant size (PS), width of the central petiole (WCP), length of spitule attached to the petiole (LEAP), petiole length (PL) were the descriptors that showed more importance in the eigenvectors. The second trial was developed in a greenhouse in the central campus of UFRPE, were used eight accessions of Stylosanthes scabra Vog. collected in the city of Bom Jardim-PE, also was used morphological descriptors, the data were submitted to the analyses of variance, genetics parameters, Pearson’s correlation and repeatability coefficient. Were observed significant difference (P< 0.05) among the accessions for all characters evaluated, except for the plant height (PH). The characteristics showed values for heritability from 62.78 to 97.70, and for repeatability 0.19 to 0.57. The descriptors: growth habit (GH), flowering (FLO), length of spitule attached to the petiole, branching (BCH), stem diameter (SD), number of leaves (NL), demonstrated positive correlation with dry matter production. Were observed genetic differences among the accessions of the Stylosanthes spp. when in field conditions, expressing the existence of the variability among them. To identify the accessions with better dry matter production at greenhouse conditions, the descriptors: growth habit, length of spitule attached to the petiole, stem diameter, number of leaves, length of central petiole, length of lateral foliole (LLF), hairiness of leaf (HL) and petiole length, were effective, requiring no more than five evaluations to predict its real value (R²=0.80).
O potencial forrageiro das leguminosas herbáceas nativas do Nordeste do Brasil é elevado, entre elas destaca-se o gênero Stylosanthes, por sua adaptabilidade às condições semiáridas e por seu elevado valor nutritivo. Este trabalho objetivou identificar divergências morfológicas entre genótipos de Stylosanthes e estimar parâmetros genéticos, bem como identificar caracteres correlacionados com maior produção de matéria seca, com grau de confiabilidade na discriminação genotípica acima de 80%, em plantas do gênero Stylosanthes. Foram realizados dois experimentos. O primeiro foi conduzido na Universidade Federal Rural de Pernambuco (UFRPE), na área experimental da Unidade Acadêmica de Serra Talhada (UAST). Foram utilizados descritores morfológicos para auxiliar na identificação da divergência morfológica entre 13 acessos de Stylosanthes spp. do banco de germoplasma da UAST, oriundos de coletas realizadas em diferentes municípios do semiárido. Na análise de componentes principais, verificou-se que, das variáveis avaliadas, o porte da planta (PT), largura do folíolo central (CFL), comprimento da estípula soldada ao pecíolo (CESP) e o comprimento do pecíolo (CP), foram os descritores que apresentaram maior peso nos autovetores. No segundo experimento, realizado em casa de vegetação na (UFRPE), foram utilizados oito acessos de Stylosanthes scabra Vog. coletados no município de Bom Jardim – PE, também foram utilizados descritores morfológicos, os dados foram submetidos à análise de variância, parâmetros genéticos, correlação de Pearson e coeficiente de repetibilidade. Observou-se que, com exceção do descritor altura (ALT), houve diferença significativa (P< 0,05) entre os acessos, para todos os caracteres estudados. Os caracteres apresentaram herdabilidade entre 0,62 e 0,97 e repetibilidade 0,19 a 0,57. Os descritores hábito de crescimento (HB), florescimento (FLOR), comprimento da estípula na parte soldada ao pecíolo (CESP), ramificações (RM), diâmetro do caule (DC) e número de folhas (NF), apresentaram correlação positiva significativa com a produção de matéria seca. Observou-se divergência genética entre os acessos de Stylosanthes spp em condições de campo, o que mostra a existência de variabilidade entre os acessos. Para identificar os acessos com maior produção de matéria seca, dentre os acessos avaliados em casa de vegetação, os descritores hábito de crescimento (HB), comprimento da estípula na parte soldada ao pecíolo (CESP), diâmetro do caule (DC), número de folhas (NF), comprimento do folíolo central (CFC), comprimento do folíolo lateral (CFL), pilosidade da folha (PLF) e comprimento do pecíolo (CP), foram eficazes, necessitando de, no máximo, cinco avaliações para predizer seu valor real (R²=0,80).

Azedinha (Rumex acetosa L.) has pleased the consumer for its sour taste. Considered an unconventional vegetable, their redemption becomes important to allow notable gains from the nutritional, social, cultural, economic and environmental point of view. The objective was to characterize morphologically copies of azedinha obtained from seeds, determine their sensory characteristics and acceptance, as well as analyze some physicochemical parameters, and determine the absorptions of macro and micronutrients and biometric parameters during 60 days after transplanting (DAT). The experiment was conducted at the Centro de Ciências Agrárias, belonging to the Universidade Federal São Carlos - UFSCar in the city of Araras - SP. Biometric parameters were evaluated (length of the leaf, relative leaf area, fresh and dry weight of shoots) and the macro and micronutrients absorption march from plants collected at 15, 20, 25, 30, 35, 40, 50 and 60 DAT. They evaluated the length, width and length / width ratio of leaf blade; petiole length and width close to the blade; diameter of the stump; the shoot length; length of ochreas; shape of the leaf blade; kind of apex; base form; type of veining and type of margin of the leaf blade; type of ochreas; characterization of the stem; length and diameter (neck) of the root. It also determined the levels of ascorbic acid, phenolic compounds and chlorophyll parameter. For sensory analysis was used the Quantitative Descriptive Analysis (QDA). Sensory analysis of acceptance was conducted with 52 judges, in relation to vii appearance, aroma, flavor, texture and overall impression, as well as purchase intent. The biometric parameters increased over time after transplantation and most markedly after the recommended times for harvest (20 and 35 DAT). The maximum levels of macro and micronutrients accumulated in the shoot, in descending order were as follows: K > N > Mg > P and Fe > Mn > Zn > Cu. The morphological descriptors with greater discriminatory power for azedinha were the types of margin and venation of the leaf blade, the characterization of the stem, the presence of ochrea and shape of the leaf blade, ranging from sagittate the hastate. It also infers that the best harvest time is between 20 and 35 DAT. The average content of ascorbic acid was 10,25 mg 100g-1 sample, total phenolic 291,46 mg of gallic acid 100 g-1 dry weight and chlorophyll parameter was 36,6 SPAD units. As for the quantitative descriptive analysis, the leaves of azedinha framed up closer to dark green; most have arrow or spear shape; smooth; with sharp aroma of grape skin; more acid flavor, such as green blackberries; there was no residual bitterness; they were folding; wrinkle free; soft to chew and thin. Regarding the acceptability test, the notes to the variable color, flavor, texture and overall acceptability were high and most judges would buy this vegetable.
A azedinha (Rumex acetosa L.) tem agradado o consumidor por seu sabor ácido. Considerada hortaliça não convencional, seu resgate se torna importante ao possibilitar ganhos notáveis do ponto de vista nutricional, social, cultural, econômico e ambiental. Objetivou-se caracterizar morfologicamente exemplares de azedinha obtidos de sementes, determinar seus atributos sensoriais e aceitação, bem como analisar alguns parâmetros físico-químicos, e determinar a marcha de absorção de macro e micronutrientes e os parâmetros biométricos durante 60 dias após transplante (DAT). O experimento foi conduzido no Centro de Ciências Agrárias, pertencente à Universidade Federal de São Carlos - UFSCar, no município de Araras – SP. Avaliaram-se os parâmetros biométricos (comprimento da lâmina foliar, área foliar relativa, massas fresca e seca da parte aérea) e a marcha de absorção de macro e micronutrientes de plantas coletadas aos 15, 20, 25, 30, 35, 40, 50 e 60 DAT. Foram avaliados o comprimento, a largura e a relação comprimento/largura das lâminas foliares; comprimento e largura do pecíolo próximo à lâmina; diâmetro da touceira; comprimento da parte aérea; comprimento das ócreas; forma da lâmina foliar; tipo de ápice; forma da base; tipo de nervação e tipo de margem da lâmina foliar; tipo de ócrea; caracterização do caule; comprimento e diâmetro (colo) da raiz. Foram determinados também os teores de ácido ascórbico, fenólicos totais e o parâmetro clorofila. Para a análise sensorial foi utilizada a Análise Descritiva Quantitativa (ADQ). A análise sensorial de v aceitação foi realizada com 52 julgadores, em relação à aparência, aroma, sabor, textura e impressão global, além da intenção de compra. Os parâmetros biométricos aumentaram ao longo do tempo após o transplante e, mais acentuadamente, após o intervalo estimado, pela literatura, para a colheita (20 a 35 DAT). Os teores máximos dos macro e micronutrientes acumulados na parte aérea, em ordem decrescente foram respectivamente: K > N > Mg > P e Fe > Mn > Zn > Cu. Os descritores morfológicos com maior poder discriminatório para a azedinha foram os tipos de margem e nervação da lâmina foliar, a caracterização do caule, a presença de ócrea e a forma da lâmina foliar, que vai de sagitada a hastada. Infere-se também que, para mudas obtidas de sementes, a melhor época de colheita é entre 20 e 35 DAT. O teor médio de ácido ascórbico foi 10,25 mg 100g-1 de amostra, de fenólicos totais foi equivalente a 291,46 mg de ácido gálico 100g-1 de massa seca e o parâmetro clorofila foi de 36,6 unidades SPAD. Quanto à análise descritiva quantitativa, as folhas de azedinha enquadraram-se mais próximas à cor verde escura; a maioria possui formato de seta ou lança; lisas; com acentuado aroma de casca de uva; sabor mais ácido, como o da amora verde; não havia amargo residual; eram dobráveis; sem rugas; macias ao mastigar e finas. Em relação ao teste de aceitabilidade, as notas para as variáveis aparência, sabor, textura e aceitação global foram altas e a maioria dos julgadores comprariam essa hortaliça.

Повний текст джерелаPenicillium nordicum is an important contaminant of cured meat products, representing 10% and 26% of the Penicillium spp. isolated, respectively, from the air or the products in a survey managed in Italy (Battilani et al., 2007). Several P. nordicum cured meat isolates proved to be important producers of ochratoxin A, OTA (Sansom and Frisvad, 2004; Pietri et al., 2006; Battilani et al., 2010). Currently, the appropriate setting of environmental conditions (temperature, relative humidity and air circulation), is the only accepted tool to prevent the uncontrolled growth of P. nordicum inside dry-curing plants through a carefully structured Hazard Analysis Critical Control Point (HACCP) plan (Asefa et al., 2011; Virgili et al., 2012). Even if the HACCP system has been successfully applied in the food industry, there are food safety hazards not carefully considered. This is especially true with regard to mycotoxigenic hazards associated with animal food products. The term “mycotoxigenic hazards” is used by Asefa et al. (2011) to describe pathogenic yeasts and toxic secondary metabolites of toxigenic moulds that contaminate food products and affect food safety. Most HACCP plans in food processing activities, such as the production of cheese and dry-cured meat products, considered mainly bacterial agents (Arvanitoyannis and Mavropoulos, 2000; Barbuti and Parolari, 2002), even if such food products get often contaminated with mycotoxigenic fungi and their metabolites (Spotti et al 1989; Spotti et al., 2001a; Battilani et al 2007). Therefore, it should be crucial to define a HACCP plan specifically focused on the mycotoxigenic hazards. The identification, control and standardization of the surface mycoflora of cured meat products is mandatory to preserve the productions safety and the consumers health. This is the context of the effectiveness and reliability evaluation for the Penicillium spp. identification methods of interesting species for food production. In this context, the research project of this PHD thesis tried to fill some gaps of knowledge with the attempt to limit the mycotoxigenic risk in the cured meat products chain. The following topics were faced: 1. study of the composition and dynamic of fungal microflora present on the surface of cured meat products (salami) and the air of seasoning environments taking into account the influence of some process parameters (starter inoculum, curing temperature, stage of seasoning). 2. development of a MALDI TOF MS method for the identification of Penicilium at species level for future direct screening perspectives of the microflora present on cured meat products. 3. comparison and integration of different techniques, as morphological, molecular and mass spectral analysis, for the identification of Penicillium species in cured meat products. 4. evaluation of selected yeasts, isolated from dry-cured ham surface, to compete with P. nordicum and to inhibit OTA accumulation in the perspective of their use as surface starter biocontrol agents.

Повний текст джерелаThe purpose of this work was to evaluate the development of Enterolobium contortisiliquum (Vell.) Morong seedlings produced with different substrates combined with irrigation water blade. The study was developed in the Tree Nursery of the Department of Forest Sciences at the Federal University of Santa Maria (UFSM-Universidade Federal de Santa Maria). The seeds used were collected from donor trees in the region of Santa Maria (RS). The substrates used were peat-based commercial (CS) and the mixture of the latter with carbonized rice husks (CRH), forming the following treatments: S1 (100% CS), S2 (80% CS + 20% CRH), S3 (60% CS + 40% CRH) and S4 (40% CS + 60% CRH) and the gross blades of daily irrigation water - GB-Gross Blades were 4, 8, 12, 16 and 20 mm.day-1. The design used was randomized blocks (four blocks) in a factorial scheme. The parameters height (H), stem diameter (SD) and H/SD ratio were obtained in a factorial scheme 4x5x4. For the aerial dry mass (ADM), root dry mass (RDM), total dry mass (TDM), ADM/RDM ratio and Dickson Quality Index (DQI), the factorial 4x5 was used respectively for the factors CS and irrigation blade, these parameters were obtained 150 days after sowing. One hundred and twenty days after sowing, the physiological parameters, chlorophyll a, chlorophyll b, total chlorophyll and carotenoids were evaluated and correlated with the morphological ones (H, SD and H/SD), also seen at 120 days. In this analysis we used 4x3 factorial, represented by four substrates and three blades gross daily irrigation (4, 12 and 20 mm.dia-1). The results indicated that the substrate based on peat mixed with 20% carbonized rice husk, when combined with gross irrigation blade of 8 mm.day-1 provides the appropriate seedlings Enterolobium contortisiliquum growth with greater economy of water and substrate. The correlation of morphological and physiological parameters observed in seedlings is low, so H, SD and H/SD may not be used for reference on the contents of chlorophyll. At 120 days after sowing, the height was greater in the 4 and 12 mm.day-1, possibly because 8 mm.day-1 was not used for analysis, while the diameter proved superior at S1 and S2, confirming the response at 150 days. As to the chlorophyll and carotenoid contents, they were larger when the seedlings received smaller amounts of water daily, indicating that the greater water blade compromised the seedling development and 20% of rice husk mixed with peat.
Este trabalho objetivou avaliar o desenvolvimento de mudas de Enterolobium contortisiliquum (Vell.) Morong produzido sob diferentes substratos combinados com lâminas de irrigação. O trabalho foi desenvolvido no Viveiro Florestal, do Departamento de Ciências Florestais, Universidade Federal de Santa Maria (UFSM). Foram utilizadas sementes coletadas de árvores matrizes na região de Santa Maria (RS). Os substratos utilizados foram comercial a base de turfa (SC) e a mistura deste à casca de arroz carbonizada (CAC), constituindo os seguintes tratamentos: S1 (100% SC), S2 (80% SC + 20% CAC), S3 (60% SC + 40% CAC) e S4 (40% SC + 60% CAC) e as lâminas brutas de irrigação diária LB foram de 4, 8, 12, 16 e 20 mm.dia-1. O delineamento utilizado foi blocos casualizados (quatro blocos) em esquema fatorial. Os parâmetros altura (H), diâmetro do coleto (DC) e relação H/DC foram obtidos em esquema fatorial 4x5x4. Para a massa seca aérea (MSA), massa seca radicular (MSR), massa seca total (MST), relação MSA/MSR e Ìndice de Qualidade de Dickson (IQD), utilizou o fatorial 4x5, respectivamente para os fatores SC e lâmina de irrigação, parâmetros que foram obtidos 150 dias após semeadura. Aos 120 dias após semeadura foram avaliados os parâmetros fisiológicos teor de clorofila a, clorofila b, clorofila total e carotenoides, os quais foram correlacionados aos morfológicos (H, DC e H/DC), também observados aos 120 dias. Nesta análise utilizou-se fatorial 4x3, representado pelos 4 substratos e 3 lâminas brutas de irrigação diária (4, 12 e 20 mm.dia-1). Os resultados indicaram que o substrato a base de turfa misturado com 20% de casca de arroz carbonizada, quando combinado com lâmina bruta de irrigação de 8 mm.dia-1 proporciona crescimento adequado às mudas de Enterolobium contortisiliquum, com maior economia de água e substrato. A correlação dos parâmetros morfológicos e fisiológicos observada nas mudas é baixa, assim H, D e H/DC não podem ser utilizados para referenciar sobre os teores de clorofila. Aos 120 dias após semeadura, a altura foi maior nas irrigações de 4 e 12 mm.dia-1, possivelmente, porque 8 mm.dia-1 não foi utilizada na análise, enquanto o diâmetro mostrou-se superior em S1 e S2, confirmando a resposta aos 150 dias. Em relação aos teores de clorofilas e carotenoides, estes foram maiores quando as mudas receberam menores quantidades de água diariamente, indicando que a maior lâmina compromete o desenvolvimento das mudas e com 20% de casca de arroz misturado à turfa.

Повний текст джерелаWhile environment pollution and forest disappearance are constantly increasing physiological functions and biochemical – biophysical reactions of trees are gaining growing significance. Conifers are the most sensitive indicators of pollution of all the kinds of trees; they, using their morphological changes, can signalize about aberrant environmental condition. Žemaitijos National Park was established by Lithuanian Republic Highest Council in 1991 in order to conserve the landscape complexes of national importance and anthropoecosystems, representing the nature and culture distinction of Žemaitija ethnografical district. Besides, one of the main purpose of Žemaitija National Park is to save, arrange and regulate the using of these nature and culture resources. In the 7th decade it was bothered about the conserving the single objects – exposures, trees, mounds, buildings etc., some of them was provided the status of nature or culture monument. According to international methods of forestry monitoring (Manual on Methods <…>, 1994), 408 vulgar firs (Picea abies (L.) H.Karst) have been investigated. The main indices of the 1st level forestry monitoring have been assessed: Kraft rating, perimeter, the condition of treetop, the amount of dead branches, crop, the age of thorn persistence, tree form, the type of lesion, defoliation, 1/3 of defoliation and violation that can be seen visually. The age of thorn persistence, defoliation and 1/3 of defoliation have been chosen as main... [to full text]

Many social and economical changes have occurred within the three recent decades, increased consciousness of the society changes the life style and the need for higher standards of life, they subsequently revealed the necessity of more integrated attitude towards food safety. The structure of production, processing, sales and consumption of agricultural products has changed. Increased exchange of animal products allowed users to get cheaper food and bigger variety thereof, but tracing the path of products from the manufacturer to the end user became more difficult. Today the situation in different sectors of Lithuanian agriculture is changing. As the amount of farms is decreasing, the amount of some of the bred animals is decreasing as well. According to the data from the Department of Statistics, there currently are 105000 farms breeding cattle in Lithuania. In the beginning of 2012, there were 748000 cattle, 9264000 pigs, 9466300 birds, 79000 sheep in our country. The demand for poultry, especially turkey, is increasing the most, the need for sheep meat, goat meat, rabbit meat, game meat is gradually increasing. It is associated with the change of attitude of users towards healthier food. Responsibility for the final product... [to full text]

Повний текст джерелаThe eucalyptus gall wasp (Leptocybe invasa) is a pest that causes serious damage in young plantations and seedlings of eucalypt. However, there is still no method of control to combat this pest. Therefore, there is a challenge to develop plant materials that can offer higher degrees of resistance to this pest. Thus, this study aimed to determine the response of different Eucalyptus clones exposed to the attack of eucalyptus gall wasp. In order to undertake the study clones of eucalyptus were divided in two subgroups: exposed plants and unexposed plants. The results showed that the attack of eucalyptus gall wasp affected growth in height and collar diameter in all clones evaluated in comparison with the average growth of unexposed plants. In terms of absolute values there was a higher effect of parasitism on growth in percentage in the height variable than in collar diameter. Regression curves determined that all clones were susceptible to the attack of eucalyptus gall wasp. The quality of infested plants showed low levels of robustness being adequate to sturdiness quotient. The visual symptoms associated with parasitism were observed in all clones, presenting different average numbers of presence of oviposition symptoms for clone. The development of galls was confirmed in all infested plants, presenting no statistical difference between the values analyzed although the higher number of galls was registered in Eucalyptus urophylla and Eucalyptus urograndis than in Eucalyptus urocam. These results show the pest behavior in response to different commercial plant materials studied. Thus, this study can contribute to determine future methods to control L.invasa.

Повний текст джерелаThis thesis work is a proof of concept. It is the first part of a much larger work where we try to answer the question whether it is possible to set a link between the morphological aspects of the third body particles and the rheological parameters of the contact where they were created. The rheological measurements are almost impossible to obtain without opening the contact itself. Therefore, such a link could be a game changer especially in machine monitoring and failure prediction, which is the long-term goal of this project. In this effort, we evaluate the efficiency of supervised machine learning algorithms in linking back the third body particles with the tests from which they originate. In addition, we assess the ability of the algorithms in predicting the rheological properties of the contact from the morphological descriptors of the wear debris it produced. We held our own tribological tests using a classical pin-disk tribometer. To ensure the production of diverse third body particles, we conduct nine tests organized in three sets. One experimental condition was varied between the tests of a give set. The rheological parameters in this project were calculated directly from the in situ signals recorded during the tribotests. They are are not the usual measures but they are mechanical measurement that describe the flow of the wear debris. Regarding the morphological dataset, we chose five different descriptors to characterize the particles post mortem after the tribological tests were terminated. Those descriptors are calculated through image analysis algorithms of SEM images. Machine learning algorithms had a 40% success rate at learning from in which test each particle was created using only the shape descriptors. However, the results of predicting the rheological parameters from the morphological database were not as promising however they were essential for the future work

Повний текст джерелаThe Handroanthus heptaphyllus (ipê-roxo) species has ecological and commercial importance, being used for various purposes since timber purposes to environmental restoration, and medical purposes. Thus, the present study aimed to evaluate and establish appropriate technical knowledge for the production of forest seeds and seedlings of H. heptaphyllus process. The seeds collected in the municipality of Santa Maria (RS) formed the batch to be studied, this was divided into two portions, one for the experiment 1 and the other 2. In experiment 1, we assessed the degree of humidity - DH ( 4 replicates of 25 seeds ) and electrical conductivity - EC (two quantities of seeds - 25 and 50, and three volumes of distilled water - 25 , 50 and 75 mL). In addition to evaluating different substrates (blotting paper, filter paper, vermiculite, sand, both on and between the arrangements in addition to the scroll), to one with higher germination (G). In experiment 2, seeds were stored for 300 days in three environments (dry and cold room - SSF - 18°C and 49 % Relative Humidity (RH); clammy chamber - CUF - 8°C and 80% RH and, dry chamber and cold - CSF - 7.5ºC and 55% RH). After this period, it was determined DH, EC, G and health. Nursery evaluated the effect of two cartridge volumes (110 and 180 cm³) with four doses of controlled-release fertilizer (CRF), NPK (18-05-09) at doses of 0 (control), 2.5, 5.0 and 7.5 g.L-1. At 180 days after sowing the reviews of height (H), diameter Collectors (DC), H/DC, dry mass and leaf area. In the field underwent seedlings under light intensities of 0 (full sun - PS - control), 18, 50 and 70% shade, evaluated for 360 days checking the survival, H, DC, H/DC, total chlorophyll content, chlorophyll a/chlorophyll b, carotenoid content, initial fluorescence of the chlorophyll maximum photochemical efficiency of photosystem II. The germination of seeds of H. heptaphyllus can be done on sand with initial count (IC) seedlings at 16 and end (EnC) at 19 days after sowing. The storage of seeds of H. heptaphyllus for 300 days can be held in SSF and/or CSF, with the IC and EnC at 9 and 29 days and, at 14 and 23 days, respectively, and this represents an intermediate behavior in relation to desiccation. The CFS was the most suitable for reducing the incidence of pathogens environment. The species is nutritionally demanding responding to high dose of CRF, with a minimum dose of 7.2 g.L-1 to 110 cm³ and 6.1 g.L-1 to 180 cm³, with the potential to respond to doses higher than 7.5 g.L-1. Seedlings to field H. heptaphyllus have high survival and growth suitable for PS, however, not recommended 50 and 70 % shading. There were increased levels of total chlorophyll and carotenoids, and lower chlorophyll a fluorescence. The species in reforestation and restoration of degraded areas, including the PS is recommended.
A espécie Handroanthus heptaphyllus (ipê-roxo) possui importância ecológica e comercial, sendo utilizada em diversos fins desde fins madeireiros até recuperação ambiental, além de fins medicinais. Assim, o presente trabalho teve o objetivo de avaliar e estabelecer técnicas adequadas para o conhecimento do processo de produção de sementes e mudas florestais de H. heptaphyllus. As sementes coletadas no município de Santa Maria (RS)s formaram o lote a ser estudado, esse foi dividido em duas porções, uma destinada ao experimento 1 e outra ao 2. No experimento 1, avaliou-se o grau de umidade GU (4 repetições de 25 sementes) e a condutividade elétrica - CE (duas quantidades de sementes - 25 e 50 e, três volumes de água destilada 25, 50 e 75 mL). Além de avaliar diferentes substratos (papel mata-borrão, papel filtro, vermiculita, areia, ambos nos arranjos sobre e entre, além do rolo de papel), visando um com maior germinação (G). No experimento 2, as sementes foram armazenadas por 300 dias em três ambientes (sala seca e fria SSF 18ºC e 49% de Umidade Relativa (UR); câmara fria e úmida - CUF 8ºC e 80% UR e; câmara seca e fria CSF 7,5ºC e 55% UR). Após esse período, determinou-se o GU, CE, G e sanidade. Em viveiro avaliou-se o efeito de dois volumes de tubete (110 e 180 cm3) com quatro doses de fertilizante de liberação controlada (FLC), NPK (18-05-09), nas doses de 0 (testemunha), 2,5; 5,0 e 7,5 g.L-1. Aos 180 dias após o semeio as avaliações de altura (H), diâmetro coleto (DC), relação H/DC, massas secas e área foliar. No campo submeteu-se as mudas sob intensidades luminosas de 0 (pleno sol PS testemunha), 18, 50 e 70% de sombra, avaliadas durante 360 dias, verificando-se a sobrevivência, H, DC, H/DC, teor de clorofila total, relação clorofila a/clorofila b, teor de carotenoides, fluorescência inicial da clorofila a e eficiência fotoquímica máxima do fotossistema II. O teste de germinação de sementes de H. heptaphyllus pode ser realizado sobre areia, com contagem inicial (PC) de plântulas aos 16 dias após a semeadura e final (UC) aos 19. O armazenamento das sementes de H. heptaphyllus por 300 dias pode ser realizado em SSF e/ou CSF, sendo a PC e UC aos 9 e 29 dias e, aos 14 e 23 dias, respectivamente, sendo que esta apresenta comportamento intermediário em relação ao dessecamento. A CFS foi o ambiente mais adequado para redução da incidência de patógenos. A espécie é exigente nutricionalmente respondendo a elevada dose de FLC, com dose mínima de 7,2 g.L-1 para 110 cm³ e 6,1 g.L-1 para 180 cm³, com potencial para responder a doses superiores a 7,5 g.L-1. Mudas a campo de H. heptaphyllus apresentam sobrevivência elevada e crescimento adequado a PS, porém, não se recomenda 50 e 70% de sombreamento. Houve aumento dos níveis de clorofila total e carotenoides e, menor fluorescência da clorofila a. Recomenda-se a espécie em reflorestamento e recuperação de áreas degradadas, inclusive a PS.

Повний текст джерелаA espécie Cordia trichotoma (Vell.) Arráb. ex Steud. da família Boraginaceae é considerada uma das arbóreas nativas madeireiras prioritárias para plantios florestais na região sul do Brasil, além de ter importância na recuperação ambiental de áreas alteradas. No entanto, apesar da importância desta espécie, não existe na literatura estudos com relação à irrigação e utilização de polímeros hidroretentores na produção de mudas, assim como a influência de níveis de sombreamento e do excesso de umidade do solo no crescimento inicial a campo, com base em variáveis morfofisiológicas. O presente trabalho foi dividido em três capítulos, no Capítulo I objetivou-se definir, com base em variáveis morfofisiológicas, qual lâmina de irrigação é indicada, combinada ou não com doses de polímero hidroretentor adicionadas ao substrato, na produção de mudas de C. trichotoma, visando à redução no consumo de água. As variáveis fisiológicas da fluorescência da clorofila a demonstraram ser importantes para estudos do comportamento do crescimento de mudas em viveiros. Um crescimento adequado das mudas em viveiro foi obtido, com lâminas de irrigação de 4-8-8 mm dia-1, alternadas a cada 60 dias, sendo possível a utilização de uma menor lâmina no início do crescimento, dessa forma reduzindo o consumo de água. A utilização da lâmina de 4 mm dia-1 contínua na produção de mudas é possível, desde que associada com a adição da dose de 3 g L-1 de polímero hidroretentor ao substrato. No Capítulo II foi avaliado o crescimento inicial a campo de mudas de C. trichotoma, sob diferentes níveis de sombreamento, considerando variáveis morfológicas e fisiológicas. A parte aérea das plantas teve o crescimento influenciado negativamente na condição de pleno sol. A espécie responde com muita plasticidade às diferentes intensidades luminosas. Porém, os sombreamentos de 18 e 50% proporcionam maior crescimento e valores fisiológicos favoráveis ao desenvolvimento inicial da espécie. Identificar o efeito do excesso de umidade do solo na sobrevivência e no crescimento inicial de mudas de C. trichotoma, após plantio a campo, com base em características morfofisiológicas foi o objetivo do Capítulo III. O maior teor de microporos e de argila em camadas sucessivas do solo (0 a 20 cm) é indicativo da condição indesejável para a sobrevivência e crescimento inicial de mudas de C. trichotoma. A espécie é intolerante a ambientes com excesso de umidade no solo, não sendo recomendado o plantio em locais planos, com problemas de drenagem.
