Item Construção de redes neurais para a predição do preço de ativos da Bolsa de Valores(0202-04-27) Silva, Bruno Leonardo de Oliveira; Paiva Júnior, Sérgio de Sá Leitão; http://lattes.cnpq.br/7706717198580424A bolsa de valores se apresenta como uma alternativa de investimento para aqueles que buscam maior rentabilidade, mas em troca desse alta rentabilidade existe uma alta volatilidade, que para muitos investidores acaba resultando em operações negativas. Para contornar esses problemas, os investidores que se arriscam nesse mercado buscam métodos para analisar e até mesmo prever as movimentações de ativos. Um desses métodos é análise técnica que busca prever o movimento do ativo baseado em eventos anteriores. O objetivo desse trabalho é apresentar uma rede neural capaz de prever o preço de ativos da bolsa de valores, para aumentar a consistência em operações positivas. Para tanto, foi desenvolvida uma Rede Neural utilizando os dados de ativos da bolsa de valores, visando o sucesso da operações com a obtenção de resultados mais confiáveis. Os resultados do trabalho deixam claro que o modelo desenvolvido possui um ótimo desempenho, quando comparado com o método de análise técnica. Isso se comprova com os resultados das métricas de avaliação usadas para essa rede neural, como também as simulações de investimento com dados de diferentes ativos da bolsa de valores.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 A pronúncia do R retroflexo do inglês por alunos de uma escola de idiomas em Serra Talhada-PE(2018) Pereira, Alana Santos; Santos, Renata Lívia de Araújo; http://lattes.cnpq.br/7009377945244623; http://lattes.cnpq.br/0849895202690132his research aims to analyze the pronunciationofEnglish Language retroflex in the speech of students of a language school located in Serra Talhada-PE.For that, we use as theoretical and methodological support the assumptions of Variationist Sociolinguistics, which seeks to explain the language in use, as well as its relation with society, in order to analyze the social factors that act on the phenomenon, in the studied community of speech.In the same way, we turn to Phonetics and Phonology, in a Structuralist perspective, with the intention of describing the studied phone, as well as the linguistic factors that can act on it.Assuming that there is variation in the speech of individuals belonging to the same linguistic community, and that this variation extends to the process of learning a foreign language, we select some factors, linguistic and extralinguistic, raising hypotheses that such factors may cause a variation in pronunciationof the retroflex, namely: theposition of the phone in the word, the level of proficiency of the learner and the level of monitoring in the reading of the material used in the data collection.Thus, we recorded the speech of 10 informants enrolled in the selected school language for the research –being 5 of the basic level II and 5 of the advanced level –and proposed the reading of the following material for the collection of data that composed the present study: listof words, list of images and a text containing words that presented the retroflex, in order to ascertain our initial hypothesis that the advanced level would present greater proficiency than the basic level in the pronunciation of the phone.Finally, we performed the corpus analysis, concluding that there is variation inthe English Language learners' speech, confirming that students at the advanced level demonstrate greater proficiency in the retroflex articulation than the students at the basic level, and proving that there are both linguistic factors and factorsextralinguistics favoringvariation, such as the replacement of the retroflex/I/by the tepe by the aspirate/r/, in addition to the erasure of the phone.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 A integração comercial do Paraguai a partir do MERCOSUL e seus efeitos sobre as relações comerciais brasilo-paraguaias(2018) Carvalho, Ivyan Larissa Barros de; Freitas, Priscila Michelle Rodrigues; http://lattes.cnpq.br/3255381700202901; http://lattes.cnpq.br/5149985985448159Commercial opening of the 1990s, allows countries a greater flow of foreign capital in the economies in the countries of the world. The formation of Mercosur in 1991 was important to promote the economic development of its member countries, which allowed Paraguay greater gains in trade. However, the commercial relations established between Paraguay and Brazil are approaching from the Mercosur, but it is perceived that the commercial relationship between both narrowed from 2012, with the increase of Brazilian foreign investment in Paraguayan territory. In this sense, in order to assess the impact of trade integration, the index of creation and trade diversion for the refrigeration, cement, plastics, textiles, footwear and auto parts sectors for the period from 1997 to 2016 was calculated. results found in the survey showed that despite the Mercosur tariff reductions allowing an average increase in imports by 30%, the analysis showed that the tariff reductionsallowed a substantial increase in imports of plastics, textiles and auto parts.Item Uma análise dos níveis de ocorrência da transferência linguística na fala de estudantes de espanhol do Programa Ganhe o Mundo no interior de Pernambuco(2018) Sousa, Antonio Leandro de Melo; Dugnani, Bruna Lopes Fernandes; http://lattes.cnpq.br/6132618542893464This paper proposes to collect cases of the process of linguistic transfer and to verify in what levels they occur when students are evaluated through oral test during the learning of an additional language, the Spanish language.For theoretical basis, the assumptions of authors such as Bechara (2009), Brandão (2003), Brown (2000), González (1994), Ortíz Alvarez (2002) and Silva (2004).Methodologically, an oral test was recorded. The research environment, the Spanish course of the Program Win the World of a school in the interior of Pernambuco, was chosen considering that in this course the objective is to prepare students for an exchange, which makes the need to develop something crucial. The oral test was applied to 6 different students, each test with an average duration of 10 minutes, all carried out on the same day. After the recording, a transcription of the audios was carried out in an ethnographic proposal to observe the processes of transference in the corpus of inadequacies found in the students' speeches. The main criterion for selection of this corpus was the spontaneity of speech discarding speech data considered to be non-spontaneous; finally, a phonetic transcription was performed, only from the first part of the oral test and only from the students' answers, in order to obtain data at phonetic-phonological level.From this analysis, transference occurred at morphosyntactic, lexical-semantic andphonetic-phonological level.All students presented transfer cases in their speech. There was a transferof tenses with similar structure, similar words and sounds that are similar in Portuguese and Spanish.Item Convergência Condicional da Renda dos Estados Brasileiros: uma análise a luz do modelo de Solow com capital humano(2018) Souza, Ana Cledia Ferreira de; Lima, Sergiany da Silva; http://lattes.cnpq.br/5314745114599013; http://lattes.cnpq.br/0739821604017578In view of the marked inequality that exists in Brazil and the improvement in the macroeconomic environment after the 2000s, this study has as main objective to analyze the hypothesis of per capita income convergence of the Brazilian states in the period from 2006 to 2014. For that, this study was performed based on the production functions of the simple and increased Solow growth models using the theory of absolute and conditional convergence. The analysis was based on the data extracted from RAIS, IPEADATA, National Treasury Secretariat. The method of estimation of results was the multiple linear regression with panel data. The empirical results are consistent with the literature on economic growth, so that investment and human capital positively affect per capita GDP growth. The depreciation parameter (n + g + d) shows a negative relationship with economic growth, as discussed in theory. The empirical analysis indicates that there is presence of both absolute convergence and conditional convergence, however, the convergence velocity increases from 0.06 in the absolute convergence model to 0.13 in the conditional convergence model with human capital. This demonstrates the effect of human capital on the productive potential of Brazilian states in the long-run equilibrium. The results indicate that the public policies carried out during the period of the research had positive effects to reduce intrestadual disparities.Item Manejo produtivo e reprodutivo de suínos criados em sistema confinado intensivo(2018) Lima, Adiel Vieira de; Holanda, Mônica Calixto Ribeiro de; http://lattes.cnpq.br/4373630020897826; http://lattes.cnpq.br/3278533468345906Item 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 Variação fonológica em libras: uma análise comparativa entre sinais regionais de Pernambuco e Cear(2018) Bomfim, Gessica Maria da Silva; Santos, Renata Lívia de Araújo; Araújo, Aline Cássia Silva; http://lattes.cnpq.br/8745882722493795; http://lattes.cnpq.br/7009377945244623; http://lattes.cnpq.br/2464061790022526Linguistic variation is a natural language phenomenon. These variations range from the field of morphology, syntax, lexicon to the phonetic/phonological level, which is the focus of this work. Linguistic variation also exists because languages tend to be conditioned by linguistic and extralinguistic factors that end up greatly influencing speech, which is heterogeneous in nature. As the variation is inherent in all languages, it could not be different in BSL, even if it is a visuospatial language. This, in its turn, has its own structure, independent of the Portuguese Language. In this context, the following research deals with the phonological variation in BSL with a focus on regionalism. The objective is to make a comparative analysis between signals performed in the states of Pernambuco and Ceará. For that, 15 signs were collected and analyzed from Dicionário da Língua de Sinais do Brasil -A Libras em suas Mãos(CAPOVILLA et al., 2017). The analysis was performed on the basis of the Parameters (STOKE, 1960) Handshape (CM), Location (AP) and Movement (M), which is within the phonetic/phonological field of BSL, as well as in the theoretical considerations of Gesser (2009) and Quadros (2004), in addition to the theoretical assumptions of Variationist Sociolinguistics (LABOV, 2008 [1972]). The method used in this research was a bibliographical survey. Due to time and space, it was not possible to work with the language in its use, however, we judgedour work valid, since the objective of presenting the variation in BSL was reached, since it was possible to perceive in the results the variation in some of the observed parameters.Item O processo de tradução para dublagem: um estudo sobre Harry Potter e a pedra filosofal(2018) Silva, Tamires Ferreira dos Santos; Cavalcanti, Larissa de Pinho; http://lattes.cnpq.br/7660087236639667; http://lattes.cnpq.br/7636558218839687Does the audiovisual production we see in our native language produces the same intentions as the original version? It is from this questioning that this research will be developed: a study of translation for dubbing based on the movie Harry Potter and the Philosopher’s Stone. Aiming to investigate the mechanism used in the translation of Harry Potter and the Philosopher’s Stone, specifically, this paper analyzes the main changes from original to target language in the translation for dubbing, considering the lines from the movie in their relation to the audiovisual of scenes and whether changes of lexical-syntactical as well as semantic nature would produce different effects of meaning for the viewer. This study focuses on the various theories that revolve around the theme: translation as a process, equivalence, domestication, foreignization, transdaptation and adaptation and investigates them in speech data – from the original English and the dubbed Portuguese lines – from the movie. It was necessary to watch the movie in its two versions (original version with audio in English) and the dubbed (with audio in Portuguese) using the product released by Warner Brothers for domestic consumption on DVD. After the selection of 41 translation examples for he dubbing, due to space and the time of analysis, we restrict corpus to 12 examples, which focus on more than one dimension of translation strategies. The development of the research put it beyond the studies of translation, because in addition to translating, dubbing requires the translation to fit the movement of the character’ lips, the length of each line and the text volume. As for the textual findings, lexical and syntactical changes according to register, culture and the use of Portuguese by the target audience, which showed very little preference for translations closer to the original language. Be it to feed the curiosity of people interested in the subject, or to highlight the study of translation and translation for dubbing, this work can help clarifying issues concerning the translation process for dubbing.Item Vida útil de linguiças elaboradas com carne de bagre marinho (Sciades herzbergii) mantidas sob congelamento(2018) Anjos, Bruno Wesley Silva dos; Oliveira Filho, Paulo Roberto Campagnoli de; http://lattes.cnpq.br/8043850276929205; http://lattes.cnpq.br/7475919343582175Nowadays, the fishing industry has grown considerably, both by the increase of consumer demand and by the technological innovations. However, it is necessary to follow these innovations with the improvement in quality inspection and processing programs. The objective of the study was to evaluate the shelf-life, through physical-chemical, microbiological and sensorial analyzes of sausages elaborated with sea bream (Sciades herzbergii) stored under freezing (-20 ± 2ºC) for up to 4 months. The sausages presented increase (p <0.05) in lipid oxidation from 0.5 to 1.1 mg malonaldehyde / kg in up to 3 months and volatile nitrogen bases from 12.2 to 16.5 mg / 100g in up to 4 months storage. The water retention capacity of the frozen sausages did not change (p> 0.05), presenting an average of 85.0 ± 0.9%. The pH of the sausages decreased (p <0.05) from 6.4 to 6.0 after 2 months of freezing, presenting a slight increase after this period. The values of instrumental color L *, a * and b * decreased (p <0.05) from 62.1 to 56.4; 8.0 to 4.8; 10.2 to 7.2 after 4 months of storage, respectively. The frozen catfish meat sausages (-20 ° C) were <2 log CFU / g of thermotolerant coliforms (E. coli) and were absent in Salmonella sp during up to 4 months of storage. In the sensory evaluation, the color, odor, texture, flavor and overall acceptance received a grade equivalent to "moderately liked", with an acceptable rate of over 82%. It can be observed, therefore, that fresh type sausages made with sea catfish meat show little variation during 4 months of storage under freezing, being able to be a product with high potential of manufacture in commercial scale, thus adding value to a species of fish of low commercial value of the Brazilian coast.Item Probabilidade de ocorrência da inicialização do consumo de cigarro combinado ao consumo prévio de álcool na população brasileira(2018) Lima, Bianca Catharina de Vasconcelos Goís; Santos, Loraine Menêses dos; http://lattes.cnpq.br/4166590770317390; http://lattes.cnpq.br/8223270064800976Current evidence in the literature indicates that the initial consumption of alcohol can lead to a later use of cigarettes by cultural, psychological, emotional and social factors. Therefore, the objective of this study was to analyze the probability of initiation of cigarette consumption, once the consumption of alcohol in the Brazilian adult population, according to gender, age, race, region and income, has started.As specific objectives, it sought to verify the proportionality of risks between alcohol and cigarette consumption concomitantly; to identify which individuals initialized cigarette consumption after the initial consumption ofalcoholic beverages; analyze the time taken for its concomitant use and the factors that led to such behavior and to verify the incidence of the combined consumption of the substances mentioned above by gender. As a methodological procedure, used secondary data from a questionnaire obtained by the National Health Survey (PNS) for the year 2013. The sample is made up of 9,717 individuals, aged over 17 years, of both sexes, living in all Brazilian regions, who initialized the consumption of alcoholic beverages and who consume or can later consume cigarettes. The data were analyzed using the following survival analysis tests: Irtest, Schoenfeld, Cox-Snell and Kaplan-Meier, which identified the proportionality of the risks of the event in question and the possible risk factors (gender, race, age group, income level and region). The data obtained demonstrated that the probability of initiation to cigarette consumption due to alcohol consumption is 0.88 times higher for men than for women; white individuals, aged 18 to 28 years and the southern region of the country presented a higher probability of initiating cigarette smoking, given the previous use of alcohol. In addition, the income variable presented a direct relation with the initiation of cigarette consumption. Regarding the mean time of initiation to the concomitant use of the substances, it was found that the older an individual, the less likely the initiation of cigarette consumption, due to the consumption of alcoholic beverages. This outcome raises the possibility of intervention by Brazilian public policies that postpone consumption, through tax increases for the sale of such substances; prohibition of advertising campaigns related to alcohol and cigarettes; prohibition of advertising campaigns related to alcohol and cigarettes; in addition to the process of raising awareness among young people and women (due to the increase in their consumption over the years) through educational programs that highlight the consequences that the consumption of thetwo substances can cause.Item Descrição do beneficiamento da lagosta vermelha (panulirus meripurpuratus, Giraldes & Smith, 2016) e lagosta cabo verde (panulirus laevicauda, Latreille, 1817) na empresa Qualimar Pescados(2018) Silva, Amanda Lécia de Lima; Ferreira, Juliana dos Santos; http://lattes.cnpq.br/6621907859216486; http://lattes.cnpq.br/9302460741060257He expansion of the food products market has meant that every opportunity for innovation and acceptance, companies, industries and other types of trade develop technologies to offer the consumer a variety at the moment of supply. A benefited product is associated with several other processes of great importance, ranging from the legislation for fishing, to the packaging of fish on board and quality standards to the consumer market. This work presents the various stages that lobsters pass before they reach the processing stage, approaching information from biology, reproduction, closed period, onboard care, product quality in the company, export and others.

However this culture is still detrimental to the loss of 10% of production due to the attack of insect-pests and use of synthetic chemical pesticides. In the present work the effect of the oil of Pequi (Caryocar brasiliense Camb.) As natural defensive, was studied on the dry rot (Callosobruchus maculatus) in Beanscowpea both acquired in the city of Princess Isabelle, Sertão of Paraíba. The methodology is very simple and can be reproduced in a domestic environment, because there is no need for the use of toxic substances, the oil of pequi used in cooking and alternative medicine. For the experiment it was used only of plastic containers, account drops and domestic balance, all low cost and commercially accessible. Concentration of 0.0 mg to 167.0 mg of oil per 20g of beans were analyzed and as a result was estimated the average lethal concentration (LC50) = 98.24 by means of linear regression. The good results presented here revealed that Pequi oil can be an economically viable and affordable alternative to the management of the rot in stored beancowpea beans.Item 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 Qualidade da água e reuso em experimentos aquícolas com tecnologia de biofloco(2018) Coêlho, Aureni Pereira; Silva, Ugo Lima; http://lattes.cnpq.br/1858876631961029; http://lattes.cnpq.br/8354389878126055The present study evaluated the reuse of water in four different experiments, where the first and second experiments were carried out with tilapia culture and third and fourth experiment with marine shrimp, respectively, with biofloc technology (BFT) in the raising and fattening stages of tilapia of the Nile (Oreochromis niloticus). Nursery and juvenile shrimp production (Litopenaeus vannamei). Water collection and analysis were carried outat the Laboratory of Experimentation with Aquatic Organisms at the facilities of the Federal Rural University of Pernambuco at the Serra Talhada Academic Unit in Serra Talhada, PE, Brazil. In the experiments with Nile tilapia were used 4 circular tanks ofglass fiber with capacity of 1000L with useful volume of 800L. In the experiments with marine shrimp, 4 circular polyethylene tanks with a capacity of 20L and a useful volume of 15L were used. Water quality was analyzed based on temperature, dissolved oxygen, pH, and salinity. For the water analysis, total ammonia, nitrite, nitrate, alkalinity and total suspended solids were also monitored. The data were statistically analyzed at a significance level of 5%. All the physical-chemical variables presented significant difference after their reuse, with the exception of ammonia. The reuse of the water presented chemical modifications throughout its uses. However, it can be concluded that it is possible to re-use it in other crops with very small replenishments, provided that there is adequate monitoring and management throughout the crop so that the physicochemical and biological variables of the water remain in line with that recommended for the species.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.Item Extratos da algarobeira como alternativa de controle do pulgão preto do feijoeiro Aphis craccivora(2018) Vieira, Domingos Sávio Marques de Menezes; Evangelista Júnior, Walter Santos; http://lattes.cnpq.br/6728342264331935; http://lattes.cnpq.br/7384301568742851The extracts of plants are recommended in family agriculture, characterized by small and medium producers, mainly related to the organic production. One way of obtaining compounds or plant substances is through the isolation of active principles or specific chemical group with insecticidal action, among them the alkaloids. The Prosopis juliflora algarobeira presents several substances with insecticidal and antifungal properties. Thus, the objective of this research was to evaluate the insecticidal effect of the alcoholic and aqueous extracts of algarobeira leaves on the black aphid of the common bean Aphis craccivora (Hemiptera: Aphididae). The experiment was carried out in the UAST experimental area. Statistical analyzes were performed by analysis of variance, using the Tukey test with significance level at 5% probability, using the Sisvar 5.6 (2011) computational package. It was observed that the dosages of FAT (100, 50, 25 and 10 mL / L) did not present significant toxicity, where there was no mortality of A. craccivora. Using the aqueous extract of the algaroba, a mortality ranging from 5.94% and 30.12% of the black aphid was observed. It is concluded that the algaroba extract presented low efficiency on the mortality of A. craccivora.Item Manejo sanitário e controle leiteiro de ovelhas mestiças Lacaune e Santa Inês na EMBRAPA Semiárido(2018) Souza, Nathaly Cristina de Menezes Sá; Martins, Jorge André Matias; http://lattes.cnpq.br/9617318260953422; http://lattes.cnpq.br/7212758908210077
