Item Estudo computacional das reações SN2 e E2: efeito do impedimento estérico do substrato e nucleófilo(2017) Carvalho Júnior, Jailson Alves de; Souza, Túlio Ricardo Couto de Lima; http://lattes.cnpq.br/8553398552801408; http://lattes.cnpq.br/5851976775229056Reactions SN2 and E2 are typical reactions of organic chemistry and there are a multitude of reactions in this segment, these are presented as fundamental in the synthesis, both in industry and in nature. And based on these utilities, we will show here the influence of some variables such as substrate, nucleophile and solvent will favor one of the two reactions, although they occur simultaneously, but with predominance of one over the other in all cases. Thus, in the present work two theoretical computational methods were developed with the aid of the GAUSSIAN 5.0.8 programfor the kinetic and thermodynamic study of these reactions, as well as the ideal conditions for their occurrence. In the first part of the study, there was a relative comparison between the two reactions at the semiempirical level AM1 and PM6, in the two methods the E2 reactions did not have expected behavior for the primary alkyl halides, whereas SN2 in the AM1 method also caused anomalous results, but In the PM6 method was presented as expected. Thus the study of the E2 reactions was terminated. The second part of the study was focused only on the SN2 reactions, in which several experiments were performed with different electrophiles and nucleophiles simulating an implicit methanol solvate medium (IEFPCM) at semiempirical PM6 level. The results were optimistic and corresponded to the expectations of the study, where factors such as steric effects on the electrophile, nucleophile and reactive medium had positive influences on the final result, following a tendency of reactivity imposed by experimental analyzes.Item Produção de frango de corte industrial(2018) Sousa, Álvaro Amaral; Holanda, Marco Aurélio Carneiro de; http://lattes.cnpq.br/9825474552364226Item A pronúncia das vogais médias pretônicas em Serra Talhada – Pernambuco(2018) Souza, Ivonete de; Sedrins, Adeilson Pinheiro; http://lattes.cnpq.br/7619692078072334The present work entitled The pronunciation of the pre-vowel middle vowels in Serra Talhada-Pernambuco, arose due to the lack of studies concerning this subject in the city of Serra Talhada. In this way, it intends to characterize the Serra-talhadense dialect within the Brazilian linguistic scenario. The main objective of this work is to record the linguistic variation of the region with emphasis on the vowels performed in the pretextual position, / e/ and / o /, from the perspective of the Theory of Variation, based on the speech of 12 informants (six females and six males) varying the age group between 15 and 25 years, residents and natural of the municipality of Serra Talhada, Pernambuco. The corpus used in the study comprised 20 words that presented the context of the research (words with previous and posterior average vowels in a pre-position). From these words, 240 occurrences of the variants [ɛ,e, i, ͻ,o] were verified. The results obtained showed that the medium-low vowels [ɛ,ͻ] are the most active, in the Serra-talhadense community.Item Desempenho de codornas europeias em produção alimentadas com farelo de gérmen de milho(2018) Sousa, Álvaro Amaral; Holanda, Marco Aurélio Carneiro de; http://lattes.cnpq.br/9825474552364226The objective of this study was to evaluate the substitution of maize by corn germ meal in diets for european laying quails. A total of 120 female quail of the 107 - day - old European pedigree, distributed in a completely randomized design with three treatments and eight replicates per treatment were housed in 24 metal cages representing an experimental plot with 5 birds per plot. The parameters evaluated were: number of eggs per bird housed, egg weight, laying rate, mean daily feed intake and feed conversion per egg mass in two production cycles, each of 28 days of egg collection. In the first laying cycle, no statistical differences were observed for the number of eggs per bird housed, posture rate and average daily feed consumption, however, there was an increase in egg weight and improvement in feed conversion. In the second production cycle, no statistical differences were observed for the number of eggs per bird housed and consumption of daily ration, but egg weight, egg laying rate and feed conversion improvement were observed. It was concluded that the substitution of maize by corn germ meal in diets for European quails up to 100% increases the production rate and egg weight and improves the feed conversion rate of the birds.Item Eficiência do uso da água e nutrientes da palma forrageira sob diferentes regimes hídricos e sistemas de plantio(2018) Assís, Méry Cristina de Sá; Silva, Thieres George Freire da; http://lattes.cnpq.br/0213450385240546; http://lattes.cnpq.br/6998116555134928Forage cactus is a crop widely used in Brazilian semi-arid region animal production systems, since it presents great adaptation to this region. Thus, the objective of this work was to analyze water efficiency and nutrient use of forage cactus submitted to different water regimes and planting systems. The experiment was carried out in Serra Talhada - PE, from 11/2014 to 11/2015, with "Orelha de Elefante Mexicana" clone forage cactus and cv. SF-15 forage sorghum distributed in randomized blocks, with 4 replications, in a 5x4 factorial arrangement, with five water blades (0%, 25%, 50%, 75% and 100% of reference evapotranspiration - ETo) and four planting systems (exclusive forage cactus, exclusive sorghum, forage cactus-sorghum consortium and palm with cover. The crops productivity was obtained at harvest time and then, efficiency indicators of water use were calculated relating crop productivity in water blade systems, and nutrient use efficiency, relating nutrient productivity to water blades. There was no interaction between water slide and water and nutrient efficiency planting systems use for N, P, K, B, Mn, Zn and Na, however it was observed that higher efficiency of water use at water blades occurred in dry or irrigated condition based on ETo 25% and between the systems, exclusive forage cactus has lower efficiency. In relation to nutrients when influenced by slides under lowest water conditions (dryland and ETo 25%) highest efficiencies are obtained, and when it comes to planting system exclusive forage cactus has the lowest efficiency. There was interaction between water blade and planting system for nutrient utilization Ca, Mg, S, Cu and Fe, being observed a greater influence of the planting system than of water blade system. Considering the water use efficiently based on dry matter, even when there was no interaction between planting systems and water blades, forage cactus planting, forage cactus intercropped with sorghum and forage cactus with cover systems are more efficient than exclusive forage cactus since forage cactus should not be fed to animals as an exclusive diet, the forage cactus-sorghum consortium becomes an efficient alternative to overcome this limitation. The application of 208.3 mm of complementary water distributed regularly during greatest deficit period promotes an increase in forage cactus green matter yield and green and dry sorghum matter. It is indicated its use mainly in forage cactus- sorghum system, since the sorghum has less water use efficiency. Mulching use, consortium with sorghum, as well as complementary irrigation with 208.3 mm in forage cactus cultivation Opuntia stricta (Haw.) Haw., are efficient strategies to promote forage production improvements. The Mulching use promotes greater extraction of nutrients by forage cactus, as well as promotes increased productivity.Item “Maria eu observei nas palavras que mandastes dizer na carta que tu ainda duvidas do meu amor, mas você não tem razão de assim se expressar”: a variação dos pronomes pessoais Tu e Você em cartas de amor rurais do sertão pernambucano(2018) Lima, Tallys Júlio Souza; Ataíde, Cleber Alves de; http://lattes.cnpq.br/4301066659702331; http://lattes.cnpq.br/6686116967696807This work aims to present the results of research on the variation of the use of TU ~ VOCÊ in the syntactic position of subject in letters of love produced in the 50s and 70s by two nonillustrious couples from a rural community of the semiarid of the Pernambuco State. In order to analyze the alternation of the treatment forms, we consider the theoretical-methodological contribution of Historical and Variationist Sociolinguistics, aiming to verify the performance of the following factors: category of fulfillment of the filled and unfilled subject and the agreement paradigm between the syntactic elements Subject -Verb (SV). In the quantitative analysis, we were able to indicate: the productivity of the treatment form VOCÊ/TU (LOPES AND CAVALCANTE, 2011), used as a strategy of referring the second person of the discourse. We also identified the preference of executing the pronoun VOCÊ in a filled category, in the two decades observed, some peculiarities in the use of the traditional pronoun TU and the gradual increase of use of the innovative form (VOCÊ) over the years. Considering the agreement paradigm, we can see that, in the remaining documentation for the analyzed period, signs of the current subsystem of treatment used in the state of Pernambuco have been already present: TU/VOCÊ use with average agreement level (SCHERRE et al., 2009; 2015 and 2018).Item Comparação de diferentes diluidores para o resfriamento de sêmen de carneiros deslanados criados no Sertão pernambucano(2018) Souza, Nathaly Cristina de Menezes Sá; Martins, Jorge André Matias; http://lattes.cnpq.br/9617318260953422; http://lattes.cnpq.br/7212758908210077Among the biotechniques applied to sheep reproduction, artificial insemination (AI) promotes greater impact on productive efficiency, due to its applicability and practicality, besides accelerating the genetic gain in the herd and controlling sanity more efficiently. The use of chilled semen may become viable to the producer since the material used and the procedures are more accessible, making possible the transport of genetic material between properties. For this purpose, semen extenders aim to improve the conservation of spermatozoa by making longer their viability outside the reproductive tract. Thus, the objective of the present study was to evaluate the technical viability of 4 extenders for the cooling of semen of rams raised in the backwoods of Pernambuco. Nine rams were subjected to semen collection and analysis, of which only 6 presented good semen traits for cooling. Ejaculates were divided into equal fractions and diluted with physiological saline, sucrose, skim milk and tris-egg yolk media, obtaining 30 million sperm/dose for each extender. The diluted samples were chilled in a refrigerator at 5 °C for 4 hours when they were then packed in ice-containing thermal boxes for transportation to the UAST chemistry laboratory. All samples were evaluated for motility, vigor and sperm morphology after 24, 48 and 72 hours of cooling. The tris-egg yolk extender was the only one able to keep sperm motile for at least 72 hours, but with motility and vigor appropriate for insemination for up to 48 hours. Moreover, such extender did not alter the sperm morphology, presenting good sperm preservation. One can conclude that the tris-egg yolk extender is technically feasible for the use and diffusion of artificial insemination in sheep raised in the backlands ofPernambuco.Item O espaço do visível e do invisível na obra “Ensaio sobre a cegueira”(2018) Barbosa, Jéssica Andrade Guabiraba; Cavalcante, Valquíria Maria de Moura; Pereira, Kleyton Ricardo Wanderley; http://lattes.cnpq.br/8902091363038170; http://lattes.cnpq.br/1979728174658046; http://lattes.cnpq.br/0952255686046703The main object of study of this work is to analyze the visible and invisible spaces as a fundamental piece of transformation of the characters within José Saramago's work on blindness (1995), since the characters change throughout the narrative. It is also intended to work the space category, as well as philosophical theories about space, in order to report the spaces that the narrative addresses. In this way we use from the reading of Luis Alberto Brandão in his work "The theory of literary space", where he presents the theories that were chosen for the study of the work. With "The poetics of the space -Gaston Bachelard" and "Microfisicalof the power" of Foucault.Item Redes neurais artificiais aplicadas à previsão de surtos de leptospirose(2018) Dantas, Elias Ferraz; Pires, Glauber Magalhães; http://lattes.cnpq.br/1159581534108735; http://lattes.cnpq.br/7510731560745063Leptospirosis is a disease of global occurrence, especially in tropical regions with high rainfall incidence and in places with poor sanitary conditions. It is a disease considered neglected, underestimated and difficult to diagnose because it presents symptoms common to other diseases, besides having a high lethality rate when reaching serious levels. In Brazil, its treatment has a high hospital cost and the disease has a high incidence in large urban centers. In the state of Pernambuco, Recife, it stands out from the other cities for having significantly larger numbers of records of Leptospirosis infections, this worrying data extols the need to support epidemiological surveillance in the fight against the disease. The objective of this work is to analyze the feasibility of using Artificial Neural Networks applied to the forecast of Time Series to perform early identification of the number of cases of Leptospirosis in the city of Recife / Pernambuco in order to demonstrate the possibility of using the technique for forecasting outbreaks as an additional means of information to contribute to the planning of health prevention actions, minimizing the social and economic impact caused by the disease.Item Informe City: plataforma para informar e gerenciar problemas de infraestrutura urbana(2018) Albuquerque, Natan de Souza; D’Emery, Richarlyson Alves; Pires, Glauber Magalhães; http://lattes.cnpq.br/1159581534108735; http://lattes.cnpq.br/3553920177544450; http://lattes.cnpq.br/6942586955274004Introduction:In recent years there has been a significant increase in popular participationin public administration due to the use of information technology and the development ofcommunication mechanisms between population and government. These technologies appliedin public management gave rise to e-government. With the emergence of new devices suchas smartphones and the increasing increase of its users, it allowed the emergence of a newapproach to participatory public administration, which became known as mobile government.Among the focuses of urban management are urban infrastructure services, with their technicalnature characterized by systems and technical subsystems. These systems are subject to theappearance of problems that can compromise its operation, it is the responsibility of the municipalgovernment to solve them in the environments of the cities. The main difficulty of the governmentin this process is to identify the emergence of these problems. One approach to minimizing thischallenge is to stimulate society so that it can help in this process by reporting the problemsencountered because they are part of their day-to-day lives. This approach has been used formany years, but through limited means such as telephone exchanges and forms, which hinder theprocess for both parties.Objective:The objective of this work was to develop a software platformthat facilitates the process of dissemination, monitoring and control of urban infrastructureproblems. Method: It was based on steps common to software development processes, suchas: requirements gathering, use case planning, modeling of system components using UnifiedModeling Language, implementation, and validation tests. The platform was developed in theclient-server architecture, through a Web service in the architectural form Representational StateTransfer (REST) and two client applications. The Web service was developed using the Goprogramming language and MongoDB as the database. The first client application was used tomanage the problems reported on the platform. It was developed to be a single-page application,using the TypeScript language with the Angular framework 6, used the GoogleMaps JavaScriptAPI v3 and was styled with the CSS Bootstrap framework. The second client application wasdeveloped in the TypeScript language using the Ionic and PhoneGap frameworks, and wasdesigned to run on the Andoid, iOS and Window Phone platforms. This application made useof the GoogleMaps JavaScript API v3. At the end of the development, the applications weretested. The Web service was validated through unit testing, white box and load performance test,black box, using the latter the Vegeta tool. The two client applications were tested by functionaltest based on use cases and test cases. After running these tests the applications were validatedbecause they met your requirements.Conclusion:After the development and validation ofthe systems, it was verified that they met the requirements and objectives raised in this work.In this way, a software platform has been developed that facilitates the population to reportproblems through their smartphones and that provides the government with a tool to managethese problems.Item Quantificação, identificaçãoe bioprospecção de fungos cultiváveis, de solo em recuperação, no semiárido Pernambucano(2018) Silva, Maiara Adriano da; Siqueira, Virgínia Medeiros de; Costa, Cynthia Maria Carneiro; http://lattes.cnpq.br/9859547718446795; http://lattes.cnpq.br/5524459744893735; http://lattes.cnpq.br/6266469936903681Oil microbial communities suffer interference from biotic and abiotic factors, and in the case of semi-arid, these communities are subject to low water availability, high temperatures andhigh incidence of solar radiation. These conditions require high adaptation of these organisms, which may represent an important source of metabolites of interest to biotechnology. In this way, this work aimed at the study of the dynamics of the fungal community of soil in recovery of the semi -arid Pernambucano collected in the Conservation Unit State Park Mata da Pimenteira, in the municipality of Serra Talhada -PE. In order to do so, the soils were collected in two seasonal periods (one in the rainy season and two in the dry season) and the isolation and quantification of total fungi and thermophilic, osmotic and halophilic fungi were carried out.Antimicrobial and enzymatic activity tests of these fungi were also carried out. In collection 1 (rainy season) the highest quantification was obtained with 2.3 x 10⁷ CFU / mL of mesophilic fungi; from the same collection it was possible to isolate all groups. In collections 2 and 3 (drought period), the highest quantification was 7.33 x 10⁶ and 5.0 x 10⁶ CFU / mL of osmotic and mesophilic fungi, respectively. There was no isolation of halophilic fungi in samples 2 and 3. Of the 22 isolates selected and submitted to the test of antimicrobial activity, the isolate 11 (Fusarium sp.) With a halo of 8.33 mm in diameter was distinguished from Bacillus subtilis. Eighteen of the twenty fungi tested showed enzymatic activity with degradation of at least one tested substrate. These results allow establishinga correlation between the characteristics of the soils and the areas where they were collected, with the microbial populations found, besides valuing the biotechnological diversity and potential of the isolated microorganisms.Item A variação no uso das preposições A, EM e PARA com verbos do tipo IR e CHEGAR: um estudo de dados de fala do sertão pernambucano(2018) Gonçalo, Maria Janete Silva; Brito, Dorothy Bezerra Silva de; http://lattes.cnpq.br/1796648943044087; http://lattes.cnpq.br/0084515999402541The present work has the main objective to investigate the use of prepositions in and out of IR-type movement verbs and to arrive in the language spoken in the pernambucan hinterland, in order to provide a descriptive-explanatory framework on the use and variation of these items in the analyzed communities, under the theoretical-methodological perspective of Theory of Linguistic Variation (LABOV, 1972) and the generalized theory of thematic roles. We analyze, therefore, contexts of variation between the prepositions a, in and for, in order to verify how the dynamics of the variation occurs and what factors could favor the use of one preposition to the detriment of another. For that, a corpus was analyzed with speech data from informants from the cities of Afogados da Ingazeira, Triunfo and Serra Talhada, all located in the hinterlands of Pernambuco. This paper presents a description of a panorama in which it becomes perceptible how variable the use of the prepositions in question is. For this, a total of 136 occurrences of the prepositions were selected in contexts where the linguistic variation between these prepositions is possible. The analysis of the data was made considering the following dependent linguistic variables: nature of the subject (+ animated) and [-animated]; verbal type: GO and GET; (Locative and Meta) and the semantic features of SP that were classified as [+permanent] and [-permanent] and [+defined] and [-defined]; was also considered the variable extralinguistic schooling (fundamental, middle and higher level). Considering these factors (dependent and independent), the GOLDVARB-X computer program was used to quantitatively analyze data that point to the fact that the preposition is more recurrent in speech contexts, as well as (+defined) andMeta [-defined] are determinants for the process of linguistic variation between the prepositions A, EM and PARA in the hinterlands of Pernambuco. The analysis was developed based on theoretical assumptions and methodological addressed by Labov (1972), Cançado (2003), Cançado (2016) Tarallo (1986), Farias (2005), Ribeiro (1996) and Ramos (1989).Item Condições operacionais de estruturas hídricas destinadas ao armazenamento de água no Vale do Rio Pajeú(2018) Rocha, Ana Karlla Penna; Barros Júnior, Genival; http://lattes.cnpq.br/4379675294862211; http://lattes.cnpq.br/9119539861018560One of the problems related to water resources in Brazil, beyond the unconscious use of the water and overused by population, it’s your irregular geographical distribuition, so that only 3% of these resources are located in the Norteast, region that owns 27,3% of the population of the country and is characterized by high annual evaporations and low precipitation rates, which are even smaller in the Semiaridregion.In this context, one of the most important rivers of the state of Pernambuco and that constitutes the greater hydrographic basin is the Pajeú, which is born in the city of Brejinho -PE and flowsinto the Itaparica dam, with a river mouth located between the cities of Floresta and Itacuruba. Because it’s an intermittent river, one of the main initiatives of the public power to increase the water supply over time has been and continues to be the construction of large hydraulic works such as dams, whose purpose it’s to store water for supplying the cities and for the cultivation of land and animal breeding. Along the Pajeú River there are 30 reservoirs with a capacity of more than 1 million m³ of water, and the Serrinha dam has the highest storage potential with 311 million m³. Due to the lack of information on the current state of these water structures, the present work proposed to raise, between august and december of the 2018, the state of conservation and the operating dynamics of sixof the main water bodies of the Pajeú River and its tributaries.Therefore were done surveys in locoof the structural and operational aspectsof this dams, as well as approaches were taken with the managers of eachone.It was found that most of the structures shows a worrying derelictionscenario, with Brotas and Jazigo dams being the most serious cases and Saco I, which has the best condition among all of them, however all can be classified as high associated potential harm and high category therefore, prone to disruption if they remain without the short-term contemplation of a preventive management and maintenance plan.Item Acompanhamento das atividades da empresa Agroceres Multimix Nutrição Animal, em Patrocínio - MG(2018) Oliveira, José Weliton Sá; Silva, Fabiana Maria da; http://lattes.cnpq.br/3782949109950763; http://lattes.cnpq.br/8330283936607107Item Análise de satisfação do consumidor da feira agroecológica (FAST) e da feira livre de Serra Talhada(2018) Souza, Cintya Mikaelly Pereira Gaia; Rocha Júnior, Cláudio Jorge Gomes da; http://lattes.cnpq.br/5767471085192721; http://lattes.cnpq.br/3531454440394612The human being seeks to always choose the best product or service in the course of life. Therefore, only making a quality item available is no longer sufficient. Consumers want to have their expectations surpassed. The present work is about a research whose main objective was to measure the degree of consumer satisfaction of the AgroecologicalFair and the Free Fair of the city of Serra Talhada, in order to identify criteria that lead to satisfaction, to describe their expectations according to with the reality evaluating from the point of view of the same the quality of the products. Data collection was done through the application of forms and the Net Promoter Score to analyze and quantify customer satisfaction. Among all the criteria evaluated the worst variable analyzed by the consumers of the Agroecological Fair was the price and this result is due to not all information from the buyers, and the Free Fair was the hygiene of the place that is due to the size of the fair and the lack of awareness of those who attend and those who try to maintain the order of the place. Through this study the level of consumer satisfaction was obtained on the products of the fairs analyzed in order to make a significant contribution to the improvement of the infrastructure and the socioeconomic conditions of the farmers and merchants and to help in the conquest of new consumers.Item Diferenciais salariais no Brasil: até onde a aglomeração explica?(2018) Pereira, Jefferson Doglas da Silva; Silva, Adelson Santos da; http://lattes.cnpq.br/8375292876575677; http://lattes.cnpq.br/7315367991475568The main porpose of this study was to identify the contribution of the worker, firm and region's effects, focusing on the density of employment as a measure of agglomeration, on the wage differential in the Brazilian regions in the period from 2010 to 2014. The analysis was made in panel , from RAIS data, which allows the monitoring of the individual over time. Initially, mincerian equations applied to OLS models were estimated, with analysis focused on fixed effects results. Afterwards, the analysis was extended to a model involving variables interaction, to verify the explanatory potential of agglomerations. Finally, the regression method was applied by instrumental variables in order to eliminate the possible endogeneity of the employment density. The results indicated that there is a wage differential, although small attributed to the density of employment, according to the literature. It has been found that education, the sector which the worker is inserted, and the size of the firm have a strong influence on wage differentials, especially higher level individuals, those working in industry and those working in larger firms. In addition, the interactions showed strong effects on wages. Finally, it is concluded that the density of employment, characteristics of individuals, firms and region, separately and through interactions, contribute to the existence of wage differentials.Item Análise do polimorfismo do gene da leptina e do gene receptor de leptina em reprodutores caprinos e ovinos da Estação de Agricultura Irrigada de Parnamirim - PE(2018) Lima Neto, João Fernandes; Lima, Ana Patrícia Souza de; http://lattes.cnpq.br/8694403879765114; http://lattes.cnpq.br/4615637220928056Item Efeito de densidades de estocagem na disponibilidade de alimento natural em berçário de camarão Litopenaeus vannamei (Boone, 1931) cultivado com tecnologia de biofloco(2018) Santos, Jorge Luiz da Silva; Silva, Ugo Lima; http://lattes.cnpq.br/1858876631961029; http://lattes.cnpq.br/3650685131155739The objective of this work was to determine the main components of planktonic food in the nursery of shrimp L. vannameiwith biofloc technology. The experiment was carried out for 28 days and a randomized design with three post-larval storage densities, D2: 2 PLs. L-1, D4: 4 PLs. L-1and D6: 6 PLs.L-1, with four replicates each, using molasses as carbon source, in the C: N ratio of 15: 1. Samples were collected weekly, with 2 liters of water in each tank, which were filtered with plankton net and concentrated in 250 mL. The qualitative and quantitative study of plankton with 1 mL sub-samples for zooplankton was carried out in the Sedgwick-Rafter chamber (ind.L-1). The phytoplankton was evaluated in slides and coverslips (nº cells.mL-1) analyzing 0,1 mL, bothunder light microscope. The temperature values remained close to 22 ° C, below the ideal temperature for L. vannameicultivation, since the appropriate range for this species is between 26 to 33ºC, but the dissolved oxygen was in the ideal conditions for its culture, which should be above 4.0 mg.L-1and during the experiment remained above 8 mg.L-1. The development of shrimp did not show any difference between the treatments, for the final weight variable, since the survival, the D2treatment obtained the highest survival (> 72%) and the production in D6was higher than in the other treatments (2.98 Pls.L-1). The zooplankton community in the nursery tanks was represented by 23 genera, distributed among the groups Rotifera, Protozoa, Nematoda, Platelmintos and Cladocera. The Protozoa group presented the most diversification, regardless of the treatment, and also presented the highest abundance (> 66%). The main genera of Protozoa were Aspidisca, Euplotesand Trinema, and the phytoplankton community was composed of 16 genera, distributed in the classes Chlorophyceae, Bacillariophyta, Cyanophyceaeand Dinophyceae, the dominant class was Bacillariophyta(> 41%), with the genera Naviculaand Cyclotella. The density of 4 PL.L-1gave the highest density of zooplankton, but for the phytoplankton the density of 6 PLs.L-1was the one with the highest amount.Item Efeito de fontes de carbono no berçário de camarão Litopenaeus vannamei (Boone, 1931) cultivado com tecnologia de biofloco no semiárido pernambucano(2018) Silva, Joyce Carla Carvalho da; Silva, Ugo Lima; http://lattes.cnpq.br/1858876631961029; http://lattes.cnpq.br/5764032184191409The objective of this work was to evaluate the cultivation of Litopenaeus vannamei shrimp during the nursery phase in a biofloque system and zero water exchange using molasses, wheat, cassava and sugar sources. The experiment was conducted at the Laboratory of Experimentation of Aquatic Organisms, Serra Talhada, PE, Brazil. The shrimp nursery was held during 45 days of cultivation. A total of 20 circular polyethylene tanks with an area of 0.05107 m2, supplied with 15 L were used, with no water renewal and constant aeration using radial compressor (120 W) and porous stones. It was adopted a completely randomized design with 5 treatments and 4 replicates, by adding four carbon sources: molasses (ME), sugar (AC), manioc starch (FM), wheat flour (FT) and a treatment control (CT) without the application of carbon sources.The carbon sources were applied daily in the treatments (ME, AC, FE and TR) in a ratio carbon (C) and nitrogen (N): 15: 1. L. vannamei post-larvae with a mean weight of 0.2 g were populated with 8 animals per culture tanks at a density of 156.6 shrimp / m2. The shrimp were fed daily at a frequency of 3 times daily with a commercial feed containing 40% crude protein. During the period of the experiment, the physicochemical variables of the water were monitored: temperature (° C), dissolved oxygen (mg / L), electrical conductivity (mS / cm), salinity (g / L),potential oxy-reduction (mV), total dissolved solids (mg / L), and Hydrogenion potential.The use of carbon sources did not influence the mean values of the physico-chemical variables of water quality, being satisfactory to the good development of the prawn larvae. At the end of the cultivation, the zootechnical performance with respect to survival, final biomass and feed conversion factor presented significantly better values with the use of cassava and wheat flour as carbon sources.Item Desenvolvimento de um objeto de aprendizagem para ensino da língua portuguesa(2018) Aquino, Thiago Rodrigo de; Almeida, Isledna Rodrigues de; http://lattes.cnpq.br/8142534647575696Introduction: According to the Program for International Student Assessment (PISA), a program developed by the Organization for Economic Cooperation and Development (OECD), Brazil ranks 59th in the world education ranking. Through a study carried out byPISA in 2015, the students had low performance, with an average of 407 points, where the ideal score would be 698. Another worrying factor is that according to the Ministry of Education (MEC), students finish elementary school unable to read and write properly. According to the Basic Education Development Index (IDEB), the level of learning in the sixth to ninth grade has not improved sufficiently, over the years this level has been decreasing. The Federal Government has invested in education, where it distributed more than 600 thousand tablets in all public schools in Brazil, with the idea of modernizing, and preparing students for the future. This is a small laptop computer, which already comes with software to prepare the student for the National High School Examination (ENEM), these tablets are also used as a support material for classes by teachers and students. In view of these problems, government investments, and the students' access to this technology, has the proposal of developing a Learning Object (OA), seeking to improve teaching and evaluation method, providing greater student interest and automation of the teachers' work.Objective: this work aims to build a Learning Object, in the form of a game, in order to motivate and help the students of the sixth year in learning the Portuguese language. Methodology: in the development of the tool followed a five-step process that occurred in a sequential manner: 1. Determine the subject to be treated in OA; 2. Raise system requirements; 3. Define the proposed system architecture; 4. Develop OA and 5. Validate OA.Results: The learning object was validated with fifteen students at the Cônego Torres school in Serra Talhada -PE. The OA contributed to the students' learning, as they were more interested in learning using the tool and were able to improve their knowledge. The initial median of the students was 7.0 before they used the OA, median calculated on top of each student's grades. After using the OA, the median of the students increasedto 9.0 with a positive result, improving students' learning.Conclusion: it was concluded that expectations were met, both for the students and the teachers who were satisfied, because the tool had a huge contribution in the students' learning, the students were motivated more to learn through the game,and the same complemented the teaching work. Students learned the content easily. OAs are still poorly used in schools, but we conclude that they can be present in the student's daily life, serving as a complement to the subjects studied in the classroom.
