The aging process affects many systems of the human body, including: autonomic nervous system, which can be assessed by heart rate variability (HRV); cellular structures, such as telomere length; and mechanisms of regulation of the inflammatory process, which can be evaluated by inflammatory markers such as high-sensitivity C-reactive protein (hsCRP). The combined analysis of these variables enables the study of the aging process in a multidimensional way. Additionally, the effects of hormone replacement therapy (HRT) on HRV are contradictory. In this way, we conducted the study I, which aimed to investigate the effects of HRT on HRV in healthy postmenopausal women. Two groups were evaluated: Group 1 (G1): 20 women who did not use HRT (60 ± 5.89 years) and group 2 (G2): 20 women undergoing HRT (59 ± 5.70 years). The electrocardiogram was recorded in supine position for 10 min. Spectral analysis included low and high frequency in absolute (LF and HF) and normalized (LFnu and HFnu) units. LF/HF ratio was also calculated. Symbolic analysis (0V%, 1V%, 2LV% e 2UV%), Shannon and conditional entropy were calculated. LF, LFnu and LF/HF ratio were higher, whereas HFnu was lower in G2 than in G1. Correlations between complexity indices and HFnu were significant and positive only in G1. We conclude that women undergoing HRT had higher cardiac sympathetic modulation and reduced cardiac vagal modulation compared to women not using HRT. Moreover, the expected positive relationship between cardiac vagal modulation and HRV complexity was found only in the group not undergoing HRT, indicating that vagal modulation in women under therapy drop below a minimum value necessary to the association to become apparent, suggesting an unfavorable cardiac autonomic modulation in spite of HRT. Considering the findings of the study I, we chose to adopt the use of the therapy as an exclusion criterion for the study II. Thus, the study II aimed to examine the aging effect on heart rate variability in supine and standing, on serum hsCRP and leukocyte telomere length, as well as to verify the age at which the changes caused by aging process are accentuated. One hundred and ten volunteers were divided into five groups according to age: G21-30 years, G31-40 years, G41-50 years, G51-60 years, and G61-70 years. Venous blood samples were collected for measurements of serum hsCRP and telomere length. ECG signals were recorded in rest supine and standing (15 min in each posture). HRV was assessed by spectral analysis in low and high frequencies in absolute (LF e HF) and normalized (LFnu e HFnu) units; symbolic analysis (0V%, 1V%, 2LV% e 2UV%); Shannon entropy; and complexity index (CI) and normalized CI (NCI) from conditional entropy. The main results were: 1) HF and 2UV% reduction (vagal modulation) in G51-60, and 0V% increase (sympathetic modulation) and NCI reduction (complexity) in G61-70, in supine; 2) less efficient response to postural change from supine to standing with advancing age; 3) hsCRP increase in G51-60; 4) telomere shortening in G61-70; 5) in supine, HRV indices showed stronger relationship with the principal component of most relevance from the multivariate principal component analysis, compared to hsCRP and telomere length. Considering that HRV indices in supine had a stronger association with the aging process, we can conclude that the decrease in cardiac vagal modulation may have influenced the increase in serum hsCRP (although normal values), in G51-60, since this effect is described by the cholinergic anti-inflammatory pathway. Decreased cardiac vagal modulation and increased hsCRP may have contributed to the telomere shortening identified in the following decade (G61-70). In this way, we must consider the importance of preventive actions prior to the onset of aging effects, particularly in the 41-50 age range, in an attempt to attenuate the natural effects of senescence.

The objective of this study was to analyze the structure, composition, trophic ecology and food items shared by the fish fauna in the stream Beija -Flor, located in Jataí Ecological Station ( 21 ⁰ 36'32 .8 " S 47 ⁰ 48'0 .54 " W ), besides characterizing the trophic ecology of the species Hemigrammus marginatus, one of the most abundant in the Beija-Flor stream. The samples of fish were collected monthly from August 2011 to July 2012, using gill nets, trawl nets and baited traps in five sampling stations distributed along the Beija-Flor stream. The fish were fixed in 10% formalin in the field and in the laboratory were identified and subjected to biometric measurements. The stomachs were weighed and transferred to 70% alcohol and stomach contents were examined under a stereomicroscope to the lowest possible taxonomic level. Forty four fish species belonging to 33 genera, 16 families and 5 orders were collected. Most species were accidental ( 43.18 % ), followed by constant species ( 38.64 % ) and accessory (18.18 % ). The diet of 30 species was analyzed. The main dietary habit was insectivorous, followed by omnivorous habits, herbivorous, piscivorous and detritivore. The dietary overlap was high in several species during periods of dry and flood. Hemigrammus marginatus was classified as an insectivore. Food items of autochthonous origin of the orders Ephemeroptera and Trichoptera were more important during the dry season, while the items of allochthonous origin of the order Hymenoptera, were more important in the rainy season. The increase in the quantity and variety of food items during the flooding causes some species of fish to become more generalist and share food resources. Hemigrammus marginatus, Astyanax altiparanae, Metynnis maculatus, Serrapinnus notomelas and Oligosarcus pintoi, have complex of interactions with the food items and can be considered key species for stream Beija- Flor. The results showed that the stream Beija-Flor is a preserved, with high species diversity by being located within the Jataí Ecological Station, but is highly threatened by being surrounded by sugar cane plantations.

The purpose of this dissertation is investigating changes on the immunized portfolios by the analytic method of principal components analysis from an inversion movement of the term structure of interest rates. In 2012, the one year yield curve had short term's interest rate higher than long term's interest rate, featuring a decrescent profile behavior. In December 2012, the structure shape changed and became firstly flat to become, later, a positively sloped curve. The method of immunization with analysis of principal component uses a structure by retroactive term for the calculation of the facts towards the greatest variance. In this dissertation we verify that the use of a decrescent historic of the structure on term for the calculation of the components did not present inconsistencies in the immunization of the portfolio in the period that the structure on term was becoming itself crescent.

This study analyzes the microclimate effects caused by a water body in São José do Rio Preto city, which is located at an Altitute Tropical Climate region in the São Paulo State, Brazil. The main hypothesis stems from the conjunction among the air masses action in the region combined with the evaporative cooling by the water body in the built environment. The study methodology is based on the physical characterization of different environments that make up the urban environment, in determining procedures of gathering data field, in the analysis of macro and meso climatic characteristics of the region, in the treatment of microclimate data by mapping information and the formulation of guide lines for urban space occupation. The monitoring field data campaigns used meteorological measurements at fixed points to record the behavior of temperature, humidity, solar radiation, evapotranspiration, the wind speed and direction in the urban area, both in the rural environment, in the bank of the dam, in the inner city and in the suburbs. Climate general information of the region were collected by Automatic Weather Station of CIIAGRO Center for Integrated Agricultural Weather Information and the CETESB Station Environmental Company of São Paulo State - which were crossed with the data and the satellite images of INPE-CPTEC Prediction Center of Weather and Climate Research. After the field campaigns, climatic data and physical characteristics of the urban environment were processed using geostatistical methods for mapping the microclimate behavior of the studied urban areas. We concluded that the wind action over the water mass may influence the immediate surroundings, reaching approximately 1.000m depending of the topographical characteristics, of the urban occupation and the atmospheric conditions. Humidification of urban air through the water body can reduce the daily temperature peaks at approximately 3°C, however, the significant difference found in the rates of temperature and humidity in the urban canopy layer clarifies that the 9 km² of the water surface are insufficient to influence the farthest outlying areas of the dam under any climatic conditions. The low penetration of humidified air masses suggests that urban space should favor the passive action of evaporative cooling to cause microclimatic effects to mitigate the temperature amplitude in low vegetated areas and in a highly waterproofed city.

And the world at full speed, with its re-engineering and mass production, would bring hope to men. It was possible to believe in the prosperity of technique as a compensation for the gap imposed by the Second World War. In a blend of sepia and black and white, reminder of a bygone cinema, the screen is filled as progress, speed and the principle of quantitative values are announced. Industries and factories, cars and trams, dynamism and rush, skyscrapers and neon: here is the synthesis of the universe portraited in the beginning of The sheltering sky (1990), by Bernardo Bertolucci. As colours invade the screen, through a sequence of shots, as they indicate new happenings, the essence of all that excess was made as though it was pulled away with tweezers: Port, Kit and Tunner would lead, starting from that diegetic instant, not only their own peculiarities, but also the universalization they fitted in. Thus, in the face on the mentioned anticipating elements of a leading image for the awake senses of the spectators, we seek to analyze Bertolucci s film in the meanderings of its own historical contextualization in which the characters are inserted, since they would be sharp representation of a recent second post-war, and they saw their own rebuilding in the progress of technique and therefore, through this idealization, they walked forward searching for the compensation of intrinsic gaps. But it is clear that the characters behaviour will not be restricted to the 50s but rather on the contrary, once in earlier circunstances the individuals can be seen in the look for a path, a way out from their loneliness or any other aspect concerning the sense of their existence. In the same way, nowadays , by the means of a visible technology serving a market in constant renovation, anchors reshaped in new disguises are evident, remoulding the idea of new , are evident, and these are constantly committed to the compensation of an existencial void, of a crossing in the quest for a hold for the individual. So, starting from the very genesis of the film precursor tracks common to the creative progress, of which there are no certainties, but intuition, deduction sensitive to the heterogeneous remittance of art, the route narrated in each segment of the film will be establishing itself gradually, always by the light of a methodology fit to outline each character by their own action in order to insert them in the categories given by the diegesis itself, such as travellers, tourist and those who would be in the simultaneity of those determinations, which we can name passengers all of this indicating different manners of seeing the world. Alongside whit those classifications, it is sought to establish the very path of the aesthetic element through the trails of those individuals, first in a fleeting principle, that is, easily falling in forgetfulness, through the linkage of a time in synchrony with the past of tradition, with the present of its fulfillments and with the future pointing at wherever there may be a look of reception. Thus, between the ephemerity of things and the firmness of senses, between men s trends in the front of their supposed arts and of the perennial building of the individual mirroring himself in the immortality of the artistic object, this analysis of the film The sheltering sky begins.

A math model was applied to describe the removal of particulate matter in lawn canal built in real scale. For this purpose different initial concentrations (Co) of particulate matter were investigated, as following: 65; 131; 196; 262 and 327 mg/L. The investigated rains, containing suspended solids, were discharged on the channel which has 100 m in length and slope of 2 %. Measurements were made of particulate material through the analysis of turbidity and total suspended solids (TSS) in 26 locations along the length of the channel. The experimental data were fit to the model using nonlinear regression parameter (kd) and (C*), which correspond to the decay kinetics constant and minimum limiting values the curve removal, respectively. Fractions removed and mathematical adjustment were assessed and performed for each isolated event and also for the result set. On average, the magnitude of the relative error ranged from 0.83% to 5.11%, with the highest average value obtained for the lowest concentration of particulate matter (65 mg L- 1). Regarding the values obtained for the decay constants (kd ), which represent the frequency of removal of particulate matter, it is noted that the same trends to a minimum value for the higher initial concentrations of particles (Co) . This fact indicates that the higher the initial concentration of particulate matter (Co), the greater the extent of travel required for its removal, with a maximum observed at around 80 m, for concentrations above 196 mg.L-1.

The production of sugar, ethanol and electricity from sugar cane necessarily involves harvesting and transportation of raw materials, which are expensive and complex operations and have significant influence on the quality of the industrial raw material. The literature reports several optimization approaches related to the planning of planting, harvesting and transporting of sugarcane, however the scheduling of harvesting fronts is underexplored. This thesis intends to contribute to the state-of-art of this important issue in the context of the Brazilian agribusiness. Optimization approaches to support scheduling decisions of harvesting fronts considering the balance of harvesting and transportation capacities, as well as good agronomic management are proposed. The approaches are inspired by the representation of the problem as a lot sizing and scheduling model with parallel machines and sequence-dependent setup costs and times, a modelling technique well studied in the production planning and control literature. Three variants of this formulation, based on mathematical programming models, were developed and tested in two real case studies of medium size sugar mills. Heuristic methods based on aggregation procedures and mathematical programming have also been studied and developed to solve large scaled problems found in practice. Among the three variants studied, one presented the best solution quality within the expected execution time. Important scenario analysis were done indicating that the schedule s fulfilment provides reduction of harvesting and transporting complexity to the following season, which can generate significant saves in the cases studied. Besides that, comparing the proposed scheduling method with one of the sector s practice, it can be generated also significant cost reduction in the cases studied. The results were analyzed according to a validation methodology (descriptive facet of tetraedrum) well known in the literature.

A community can be defined purely as a group of individuals in a certain area? Since the beginning of ecology as a science, many authors have proposed theories to explain the structure of plant communities and therefore the spatial variation. However, although the accumulated knowledge has advanced to challenge the theories with each other, we have not reached many consensus within the community ecology. Likewise it has not been an easy task to establish physical or functional boundaries between the plant communities in the field, has also not been easy to establish boundaries between theories, approaches and influences of diferents areas of science, such as the biogeografia and evolution. Although some researchers have been working on attempts to establish an integrated theory was not only achieved little success and earned the antipathy of many trends or incited passions in scientific circles. On the one hand, the structure of the plant community may be the result of chance that accumulates over time and space, or by environmental heterogeneity due to specific ecological adaptations of different species. On the other hand, the gradient study indicates recognition of closed communities separated by transitional areas whose influence among communities, such highly dynamic areas, regulate their diversity, as endemic center would be essential for management and maintenance actions. Thus, the thresholds may reflect discontinuities on many different levels, but all kinds of limits can help to draw the line where there is success or failure in the prevalence of survival, growth and reproduction, sufficient to prevent the extinction of a species. In this context, the objective of this work is especially to propose a new old way to look at the structure of plant communities, trying to recognize the principles of the proposed theories from the scale of influence on spatial variation in community composition. Still, considering the current context of environmental changes caused by human activities, we will evaluate the effect of artificial transitions in the structure and diversity of communities. Furthermore, given the important contribution of ecotonal areas as endemic centers, we evaluate the contribution of the occurrence of threatened species in these areas for the Brazilian ecosystems conservation status. In this analysis, greater focus was given to the Cerrado, as the Brazilian Phytogeographic Domain presenting transition areas with almost all other ecosystems, with the exception of Pampa. Our results indicated a greater heterogeneity among the grasslands than in the savanna, but in thin scales both guard similarity close to 1, with a higher similarity between samples than expected by chance. This allows us to consider that the fine-scale continuum theory applies to structuring of communities and its spatial variation. In a coarser scale, communities vary as of continuum, in which the case studied in Itirapina Ecological Station, the continuum is represented by the part of Coutinho's gradient ("Grassland – Savanna - Forest") as Grassland-Forest. However, within a mosaic of ecotones and homogeneous types of vegetation, we find gradients nested with the refinement of the scale. In this case, the influence of the scale in approaches to the structuring of the Cerrado communities could be related to fractals, from the recognition of repeated linked units. Considering the intense fragmentation of the Cerrado vegetation, the invasibility of the communities and the biodiversity loss by invasive alien species, it is necessary to carefully evaluate the effect of artificial transitions in the structure of plant communities and establish 3 effective measures of management of invasive grasses for the focus of established invasion. Still, one must consider the ecosystem conservation status are significantly influenced by the heterogeneity that should be considered in priority actions for conservation.

Aquaculture is an activity of great importance in food production, but fish survival in post- larval stages represents a big challenge. Artemia sp. is successfully used as live food, but is expensive and one of the alternatives to reduce costs is to use native species, such as natural zooplankton and fairy shrimp Dendrocephalus brasiliensis, phylogenetically close to A. salina. This study examined how changes in nutritional conditions affect the algae Ankistrodesmus gracilis, and the biochemical composition of D. brasiliensis, Artemia sp. and Daphnia magna. Moreover, we studied how different combinations of food affect the biochemical composition of Atlantic cod (Gadus morhua). The results showed that the availability of phosphorus and copper alter the biochemical composition of algae and affect the production of chlorophyll, growth rates and resistance to metal; D. brasiliensis showed good results in terms of the content of carbohydrates and protein, and a change in the lipid composition according to sex and stage of development of animals; cod showed better results when feed on wild zooplankton added to the cultivated and enriched organisms (rotifers and Artemia) in tanks. Based on these results, we conclude that the environment and nutrient availability in the case of microalgae, affects the biochemical composition and ability to handle contaminants. The biochemical composition of zooplankton can affect higher trophic levels, affecting both the biochemical composition. For these reasons, it is important to know the optimal cultivation conditions in order to achieve the best results in each trophic level.

With about 1.000 species and 23 genera occurring in Brazil, Myrtaceae is one of the most important families in floristic surveys, mainly in Cerrado and Atlantic Forest areas. The National Forest of Ipanema is occupied mostly by Atlantic Forest and small areas of Cerrado; it is also possible to observe signs of human exploration in the past in the area. The main objective of this work is to improve the knowledge of Myrtaceae in the National Forest of Ipanema. For this, field trips were made between September 2012 and March 2013 and the collections of the following herbaria were analyzed: CCTS, ESA, IAC, SP, SPSF, UEC. After data analysis 23 species of Myrtaceae and 6 genera were found: Eugenia (10 species), Myrcia (4 species), Psidium (4 species), Campomanesia (3 species), Calyptranthes (1 species) and Plinia (1 species). Descriptions, illustrations, maps of geographical distribution and keys of identification of the species were prepared. After data analyzis C. neriiflora was identified in the IUCN red list of threatened species as vulnerable risk, by the other side, Psidium guajava occurs at high frequency, as it is an invasive species, it could endanger the local biodiversity. All the collected specimens were deposited in CCTS collection.

The present work consists in a study concerning the ressignifications in the narratives of Racionais MC s group of rap about the daily life of the urban peripheries in the city of São Paulo, during the years 1990 to 2000. These ressignifications about the peripheral dayafter- day would be in three aspects: religious a narrative composition of the rappers using the moral and ethical Christian notions, reviving a biblical narrative, more specifically of Livro Êxodo, and Livro Gênesis and the Jesus Christ, thus presenting a relevance of the peripheral pentecostal universe; politic the rap s subversive and critical bias, arising from the American black leaders discourse such as Malcolm X s, the Brazilian re-democratization process with political participation of the popular classes, and the hip-hop as political, cultural and artistic critic movement to the injustices and social inequalities in the urban peripheries engendered by capitalism and racism; and esthetic-musical through the notion of sample, audible clipping of a music or environment sounds (for example a car exhaust s noise), that composed with other musical elements would constitute the sonority while rap s expressivity constitutive elements, using mainly the black aesthetic-musical genres such as: funk, disco, gospel, soul, samba and pagode. Based on the albums Sobrevivendo no inferno [Surviving in Hell] (1997), and Nada como um dia após outro dia [Nothing as One Day after Another Day] (2002), I shall present their songs as narratives that hybridize political, religious and esthetic-musical elements, thus, establishing a Gospel according to Racionais MC s.

The intense urbanization generated from twentieth century and the emergence of large urban centers brought about a considerable change in the use and occupation of land ; this became very waterproof resulting in increased runoff . Problems resulting from the growth of this flow we mention floods , climate change , interference in the hydrological cycle and water balance . This problem , with the passage of time has been improving sustainable urban drainage analyzing the control flow that has to be done at source infiltration , percolation and storage . The importance of this work is to know the compensatory techniques so that they can be applied in the UFSCAR campus - São Carlos - SP . This study aimed to design, build , monitor and model a plan of infiltration, built in real scale, for stormwater management of the building with an area of 3001.3 m². The funds came from Project MCT / FINEP / Action Cross Environmental and Housing 07 /2009 Drainage - MAPLU2 - . Stormwater Management Urban 2 The soil characterization was performed considering their fitness levels , grain size, permeability, degree of compaction and profile this soil.

Vehicle fleets are an important component in several applications, moving materials and people. Examples include material handling in warehouses, factories and port terminals, people transportation as in taxi fleets and emergency services, such as medical assistance, fire-fighters and police. Fleet operation is crucial for these applications: it can mean loss of money and commercial partners in case of industry, os loss of lives in case of emergency services. Controlling the fleet to achieve efficient levels of performance is a difficult problem, though, and becomes even harder as the fleet grows. Research in the area has been linking vehicle fleet operation to Multi-Agent Systems, because vehicle fleets are naturally distributed and Multi-agent System is a convenient abstraction to cope with distributed Artificial Intelligence problems. Therefore, it is proposed a Multi-Agent System to control vehicle fleets, focusing on material handling application in warehouses. The proposed system has three types of agents: Vehicle Agent, Loading Point Agent and Storage Point Agent. Agents interact amongst themselves through messages, trying to efficiently realize the material handling in a warehouse. System implementation is done through a simulation of a warehouse operation, built on top of MASON multi-agent system simulation platform. Task assignment strategies is also an important problem, therefore four strategies are shown and tested using the simulation: CNET, Fuzzy, DynCNET and FiTA. To enable comparison among these strategies, a Genetic Algorithm is employed to systematically search good parameters for each strategy. The proposed system, as well as the simulation, are offered as a framework for development of other vehicle fleets controlling multi-agent systems and/or task assignment strategies.

The analyses of the relative condition factor in fish community and of the benthic macroinvertebrates communities structure were used as a tool for assessing the influence of disturbances and water quality in the tropical streams of the upper portion of Monjolinho River basin, São Carlos, SP, Brazil. The condition factor revealed different responses of the fish species regarding the organic pollution effect. Astyanax cf paranae was found to be a sensitive species, Phalloceros harpagos to be tolerant, and Poecilia reticulate to be resistant. The analysis of the benthic macroinvertebrate community structure showed that these populations are affected by the loss of environmental quality, resulting in great differences in species diversity, with the absence of groups considered sensitive to pollution and dominance of resistant groups. In this portion of the Monjolinho River basin it was possible to identify streams with high environmental integrity as the Espraiado stream, up to strongly polluted streams as the Belvedere stream.

The effect of using the non-preferred hand on manual preference and motor performance was assessed in two experiments. Experiment 1 investigated the short-term effect of lateralized experience on manual preference and motor performance in infants reaching. Four- and seven-month-olds were induced to use the non-preferred hand through reaching for toys contralaterally to the preferred hand. Reassessment of manual preference in reaching at the central position revealed that infants used the nonpreferred hand more frequently. That behavior was similar between both age groups. Kinematic analysis of reaching did not indicate variations coherent with shift of manual preference. Experiment 2 tested the effect of practice with the non-preferred hand on manual preference and intermanual asymmetries of performance, comparing children and adults. Different tasks requiring reaching and manipulation were practiced. Manual preference was assessed through reaching toward cards at different positions on the right and left of the participant, and inserting the card into a slot. Results showed that use of the nonpreferred hand increased after practice in both age groups. There was no effect of practice on intermanual asymmetries of performance. Results indicate that manual preference is flexible and modulated by immediate lateralized experiences.

Since 1998 it has increased the number of Community Development Banks, there are currently more than 100 operating in the country. They are a recent phenomenon and there are few studies on the cumulative impacts of this initiative in its service territory. In addition is relevant to quote the coordination and community mobilization, promotion of social currency, cultural activities, environment, health and education. These banks work with credit services, most of the time with productive credit lines and consumption, some banks proffer housing credit for renovation, expansion and even production of new housing with the self technical advice. This dissertation will examine in particular the relationship of housing production through the housing microfinance promoting by Banco Bem, Vitória -ES, and the development of its territory, with the guiding hypothesis that the Community Development Banks, in particular the Banco Bem, promote Territorial Development with its housing microcredit and free technical advice to the self, allowing housing improvements, fostering trade in materials and services in the chain of housing production and through community organization and mobilization due to the Local Development Forum. Thus is an initiative more suited to the reality of substandard clusters and potential guideline / model for Public Policy Housing in these territories. In this context, the research aims to examine the relationship between the Housing Credit via Community Development Bank, housing production, technical advice for self, Territorial Development and its dialogues with the Public Policy.

Though urban form affects the thermal environment, there are only a few legal tools that include the thermal issue in the city planning and urban design. This research established a link between urban form and thermal environment, by considering urban indexes such as the occupation coefficient, the floor space index and the vegetation cover index, to characterize the land use and occupation. For this purpose, the study area was an urban fraction of the Brazilian city of São Carlos, in State of São Paulo. Several points of the study area were taken as references for thermal measurements, while others regional data of the climate were registered by the meteorological station situated in the city skirts. The data were collected in periods representing dry weather of winter months. The measurements allowed the validation of a computational model applied for microclimatic simulation of the urban area - the ENVI-met. The best situation performed by the model was determined by comparison of real and simulated data. This process allowed data extraction by simulation of the whole area and the development of thermal maps, considering the real urban situation, a scenario of densification and a scenario of green areas. The results pointed out that the rise of the occupation coefficient causes a slight elevation of the air temperature. Even more significant tendencies were also assessed by the development of a multiple regression model, revealing the potential of the floor space index, the urban green cover and their association with the wind speed.

The Performance Measurement System (PMS) are one of the essential tools to withstand the demands of information at all levels within an organization, and also is an important means of measuring the effectiveness of their business strategy. However, due to several peculiarities present in Small and Medium Enterprises (SME), this tool is not always implemented and used in full. Given the above, this work aims to identify constraints that make it difficult the implementation and use of a PMS in SMEs. For this, a literature search and also a survey research was conducted, covering a unit of analysis of 21 industries in the metal-mechanical sector. This research was conducted in the region of Limeira, an important industrial center, located within the São Paulo state. As a result, it was found that SMEs face many difficulties in implementing PMS and this phenomenon is due to the fact that SMEs have characteristics that differ from large companies. Factors such as lack of resources, excessive informality, lack of a strategic long-term vision and lack of knowledge of this tool have been identified as existing in most of the surveyed companies. These factors added the characteristics of business, become serious constraints to the development and use of this tool.

In trawling a significant portion of the captured fauna has no commercial value and is returned to the sea, causing biological and ecological changes, with impacts on the food chain, modifying processes of energy transfer in the ecosystem. Studies on the feeding habits of demersal fish provide basic information for understanding species trophic relations. Thus, this work aimed the undestandment of the feeding habits of the most abundant fish present in the bycatch of the Xiphopenaeus kroyeri artisanal fisheries of the coast of Santa Catarina, through the analysis of stomach contents, describing patterns of similarity, overlap and trophic structure. Sampling took place seasonally, from November 2009 to August 2010, in Balneario Barra do Sul, Porto Belo and Penha. Whaling vessels from the artisanal shrimping fleet were used for trawling. After sorting the specimens, they were frozen until the completion of biometrics and stomach content analysis. Information obtained through analysis of stomach contents were quantified via the Kawakami-Vazzoler feeding index, combining the frequency of occurrence and the relative volume of the items. Species of Sciaenidae family were the most abundant. Ctenosciaena gracilicirrhus, Cynoscion jamaicensis, Larimus breviceps, Menticirrhus americanus, Stellifer brasiliensis and S. rastrifer were classified as crab eaters, while Isopisthus parvipinnis crab eater/piscivore, Micropogonias furnieri as annelid eater/crab eater and Paralonchurus brasiliensis as annelid eater, however species were found to have very similar diets, altering the intake of certain items between seasons and locations. According Morisita overlap index, 9 cases of overlap were observed in Balneario Barra do Sul, 9 in Penha and 20 in Porto Belo. The bipartite foodwebs showed generality in the intake of food, with most species carrying multiple trophic interactions. Once the Sciaenidade family is the most abundant and diverse in the sea-bob-shrimp bycatch, iv its removal seems to directly influence the ecosystem processes in the region, with most species performing a wide range of interactions. Therefore their removal will gradually change the stability of benthic community.
