We analyze the appearance of bound states in a Landau-type system for a neutral particle (atom/molecule) with induced electric dipole momentum, in the presence of a configuration of crossed electric and magnetic fields of the following scalars potential: one which is proportional to the radial distance and the other which is a Coulomb-type. Next, we consider this system under rotational effects and we determined the allowed energy levels. In the search for analytical solutions for the Schro¨dinger equation we show that the energy states of a Landau system for an atom with an induced electric dipole moment subject to potential confiners depend on the parameters that characterize both electric and magnetic fields, besides they also depend on the potential and on the numbers quantum {n,l} of the system. Moreover, the levels found in this investigation are different from the Landau levels presented in reference: C. Furtado, J. R. Nascimento, e L. R. Ribeiro (2006) [1]. And for the case where we treat the system in a rotating frame, we find the spectrum with the characterizing parameters for the lectromagnetic field, with the quantum numbers {n,l} besides its uniform angular speed of rotation. Furthermore, we observe that it is possible to recover the quantization of Landau subject to the potential confiners if we take the limit at when the angular velocity disappears.

Prenatal care, with regard to women's health, is one of the most important strategies in promoting the health of the pregnant woman to identify and intervene according to the risk assessment. In order for health care to respond adequately to women's needs, it is essential to evaluate public health services, with emphasis on Primary Care, the responsibility to coordinate care and to be the main gateway to user to the Unified Health System (SUS). In view of this, the National Program for Improving Access and Quality of Primary Care (PMAQ-AB) has been highlighted as a strategy for evaluating AB. The purpose of this study is to evaluate prenatal and puerperal care, based on the first and second cycle of PMAQ-AB. This is a descriptive, cross-sectional and quantitative approach. The sample was composed of population bases, whose sample units are 17,202 basic health units for the first cycle; 29,778 basic health units for the second cycle of PMAQ-AB, throughout Brazil. Statistical software SPSS version 20.0 was used for the analysis of the data for both descriptive and inferential statistics. These results were presented in graphs and tables constructed with the aid of the Office Excel 2010 program. The results were presented in two articles format, first dealt with descriptive analysis and analysis based on the statistical model. The first article aimed to describe the characteristics of prenatal and puerperal care performed by EqESF in cycle I and cycle II, listing the main fragilities and potentialities when comparing the regions with each other; the second one had the objective of describing the characteristics of prenatal and puerperal care performed by EqESF in cycle I and cycle.

The economic losses determined by neonatal diarrhea to the economic exploitation of animals leads both directly and indirectly to an increase in the costs of breeding. Due to the lack of studies, the etiology of neonatal diarrhea in caprine herds of the northeast region of Brazil is systematically and generally conferred to helminthes. The importance of bacteria, protozoa and mainly viruses in the etiology of the episodes of neonatal diarrhea in caprine and ovine cattle is not yet properly characterized. The aim of this project was to evaluate the presence of enteropathogens involved in occurrences of diarrhea in herds of caprine in the state of Paraíba. The methodology consisted of visits to the caprine herds of mesoregions of the state of Paraíba. Was collected two hundred twenty diarrheal stool samples from caprine up to 90 days of age. The samples were submitted to rotavirus identification by ss-PAGE. The isolated strains were submitted to biochemical tests to confirm bacterial species, followed by the determination of serogroups and genotypic groups, as well the phylogenetic analyses. The samples were also submitted to antimicrobial susceptibility testing. Each one of the samples were negative to rotavirus. Isolates were identified to E. coli, S. typhi, Shigella sonnei and Enterobacter classified phylogenetically in (9/39), D (19/39), B1 (7/39) and A (4/29). The virulence factors founded were K99 (04/39) and Stx (02/39). There were no positives isolates for K88, Sta,StbP and LT. To the antimicrobial susceptibility testing, the isolates were sensitive to Chloramphenicol, streptomycin, Amoxicillin and Ciprofloxacin, all of them being resistant to Lincomycin, Vancomycin and penicillin. The results showed that the samples derived from caprine from the state of Paraíba showed E. coli belonging to phylogenetic group B2 (9-23,07%) and D (19 –48,71%), and a high incidence of resistance against tested antibiotics.

What is the effect of leaders in the discipline of legislative propositions in the Chamber of Deputies? The internal rules in the Chamber of Deputies allow Brazilian parliamentarians a series of opportunities to modify propositions in transit in the House. Initiatives can be presented individually or collectively, either to suppress, replace or modify specific items of the original text. The objective of this study is to verify if the profile of the leaders of the 53rd and 54th legislatures have an effect on the vote of the teams in appreciation of items highlighted for separate voting (DVS). The hypothesis is that the credibility of the leader has a positive and significant effect on the maintenance of the items. To test this hypothesis will be used descriptive and inferential statistics.

After 17 years of approval of Law nº 10.216/2001, and even with Brazil's binding to the Convention on the Rights of Persons with Disabilities and the subsequent publication of the Brazilian Inclusion Law, the capacity of people in mental suffering for crimes continues to be disregarded, and the treatment of them, as a rule, is intended for hospitalization in judicial asylums. Another aggravating factor: there is no forecast of maximum temporal limitation and its release is conditional, giving room for the perpetuation of the enclosure, with the breaking of family ties and institutionalization, and for the attachment of the person who may be disinterned in this system. In view of the invisibility and the abandonment of this population, the elements of the Psychiatric Reform and the trajectory of the anti-asylum movement are persecuted in order to analyze the process of deinstitutionalization of the security measures, focusing on the cases of people who remain in the Penitenciária de Psiquiatria Forense do Estado da Paraíba (PPF/PB) with a desinterned verdict pronouncement. As methods of data collection, we initiate with documentary research, participant observation in PPF/PB, and then semi-structured interviews. For the interpretation of the material collected, qualitative analysis and content analysis are used, with the definition of the following analytical categories: institutionalization processes in the PPF/PB, Psychiatric Reform and deinstitutionalization of security measures. With the empirical research, it is verified that this system diffuses over the life of the people submitted to the security measure, which compromises the process of deinstitutionalization and produces a relation of institutional dependence. When investigating the professionals' perceptions, remains clear the distinct notions about the category of deinstitutionalization and the maintenance of a relationship of guardianship and prejudice with those subject to security measures. It is concluded that this system works against the Psychiatric Reform in its antimanicomial perspective, in view of being anchored in the notions of dangerousness and incomputability, which turns difficult to guarantee rights such as freedom, access to law and justice. Thus, it is urgent to consider the capacity of these people and transform the way the state, professionals and society relate to madness.

Several researches have been conducted with the aim of analyzing the phenomenon of the palatalization in Brasilian Portuguese (PB), of which we can highlight the Carvalho (2000), Brescancini (2002) Callou, Leite & Moraes (2002), Hora (2003), Silva (2004), Macedo (2004), Brandão (2008), Monteiro (2009), among others. However studies on the palatalization of coronal fricative in the acquisition of English as L2 are rather scarce. That said this study aims to identify the palatalization in the production of /S/ post-vocalic in the context /S/t realized by paraibanos speakers of English as L2. Specifically, we propose to identify the process of the palatalization in the interlanguage (IL) of English learners as L2, what are the factors which favor or not the application of the rule, and if there are no linguistics agents promoting palatalization. This study is based on Sociolinguistics Variationist formulated by Labov (2008 [1972]) and the theoretical basis of the Acquisition of L2 (SELINKER, 1992; ELLIS, 2003 [1994]; BAYLE, 2007). The Sociolinguistics and Acquisition of L2 interface has emerged as a new field of linguistic studies. In order to study the relationship between social context and the learning of a L2, the union of these two fields wants to explain how extralinguistic factors may interfere in using a new code. Some studies (BAYLEY, 2005; LUCENA & ALVES, 2009; CAGLIARI, 2010; LIMA, 2012) have been realized in this perspective. The corpus of this research is consisted by 18 paraibanos informants belonging to the basic, intermediate, and advanced levels. To collect speech data it was recorded the reading of eighteen sentences and two texts in English. The collected material was quantitatively analysed through the computer program GOLDVARB X (SANKOFF; TAGLIAMONTE; SMITH, 2005). The independent variables observed were level of proficiency, explicit phonological awareness, tonicity, preceding phonological context, and type of instrument. The statistical analysis performed showed, in increasing order of significance, that the variables level of proficiency in language, tonicity and preceding context were those more relevant to the implementation of palatalization.

Some studies have been conducted with the aim to analyze the acquisition process of English voiceless interdental fricative /θ/ by Brazilian speakers. Among them, we can highlight the study of Reis, 2006; Peleias, 2009; Ramos & Delatorre, 2011; Schadech & Silveira, 2013; Moreira, 2015, among others. However, few studies talk about phonological awareness development, a less recurrent approach in teaching English as L2 in regular schools in Brazil, in order to acquire the phenomenon. This way, the present study aims to analyze the production of English voiceless interdental fricative /θ/ by Brazilian speakers who received two different teaching approaches. On the one hand, students who, as in the most cases, did not obtain guidance to the phonological aspects of the target language, on the other hand, students who received instruction on the main phonetic-phonological aspects of the language, in its different levels, both in the segment and suprasgment. The study is based on Variationist Sociolinguistics, formulated by Labov (2008 [1972]); in the theoretical contribution of the Acquisition of L2 (JENKINS, 2000; ALVES, 2012) and in the acoustic theory of speech production (BARBOSA & MADUREIRA, 2015; CHIBA & KAJIYAMA, 1941; FANT, 1960)). The interface of L2 Sociolinguistics and Acquisition emerges as a new field of study that aims to analyze the multiple influencing factors in the target linguistic processing, which may be related to linguistic and extralinguistic aspects. The acoustic theory acts as an important tool in this kind of approach, since it does not leave space for possible mistakes of interpretation of the data, favoring a better precision in the analysis. The corpus of this study is consisted by 40 informants, Brazilian students of regular education of the ninth year of Elementary School II. These students constitute two distinct classes of a private school located in the state of Paraiba. To collect the data, ten words containing the English voiceless interdental /θ/ were distributed in three distinct tasks: image reading, text reading and sentence reading. The collected material was treated in PRAAT software version 5.3 (BOERSMA & WEENINK, 2014) and then analyzed quantitatively through GOLDVARB X (SANKOFF; TAGLIAMONTE; SMITH, 2005). The independent variables found were instrument type, phonological context and phonological awareness. The statistical analysis performed did not discard any of the variables analyzed by the program and the results are presented in increasing order of significance.

Marcgrave’s capuchin monkeys or blond capuchin monkeys (Sapajus flavius), Neotropical primate species newly discovered, are distributed in approximately 26 populations located in fragments of Atlantic Forest in the States of Alagoas, Pernambuco and Paraíba. These animals are classified as "critically endangered" and data on the health of these animals are scarce. The aim of this study was to evaluate the sanity of two populations of S. flavius kept in captivity in Paraíba. Research on the occurrence of hemoplasmas, with evaluation of hematologic and biochemical profiles, a survey of enterobacteria present in these two populations and investigate the occurrence of parasites was performed. Nine of 12 animals (75%) had infection 'Candidatus Mycoplasma haemomacaque ', despite the state of health of the animals did not indicate any disease. Regarding enterobacteria, we observed the presence of the genera Salmonella spp. in 87.5% (7/8), Shigella spp. in 12.5% (1/8) and Enterobacter spp. in 12.5% (1/8). Nematodes findings were identified as the species Dipetalonema gracile. Thus, we observe the importance of studies like these to learn more about the health aspects of these animals, helping in the development of management and conservation of this species in captivity projects aiming to release programs.

Violence and constant sexual abuse of homosexuals are common practices in Brazilian prisons. This work is a reflection of the results of the field research carried out at the Penitentiary Chief Justice Flósculo da Nóbrega in João Pessoa, State of Paraíba, on the creation of an exclusive area for the population of gays, bisexuals, transvestites and transsexuals. During the last eleven months of work, analyzes were made of the documents regarding the creation of this area in the State of Paraíba, the ethnography of the prison, the participatory observation with the victims, interviews with managers, employees and all those who were convicted. We identified a lack of documents that prove the official character of the policy and ensure its implementation and permanence. We conduct the ethnography and recognize the rules of coexistence of this new prison environment. Through the observation and narratives of the convicted, we show how experiences and peculiarities of the social effects of the separation of the spaces based on the criteria of sexual orientation, as well as the circumstances and contexts of the implementation of this policy. We understand that the convicted are satisfied with the reduction in physical violence practiced, but they complain about their freedom when compared to others in the same prison institution. We end with the understanding that the policy of segregation instituted decreased the number of physical violence, but it has not minimized stigmatization, nor the fragility in sociability, considering they are prevented from participating in all spaces to others. Thus, some choose to think that the LGBT area should continue, and others ignore and long for non-permanence of the space, since they prefer to give up security to have their freedom suppressed.

Cancer designate a group of heterogeneous genetic diseases characterized by uncontrolled cell proliferation. Problems in regard to effectiveness, safety as well as development of resistance to treatment foment the need for researches on new molecules with antitumor potential. Hydantoin derivatives are known to present biological activities such as antitumor and antinociceptive ones. This paper aimed at investigating the toxicity, antitumor, antinociceptive and antiinflammatory activities of the hydantoin derivative 3,5-diphenyl-imidazolidine - 2,4 – dione (IM-15). IM-15 did not induce hemolysis to the concentration of 2000 µg/mL, which suggested low toxicity in erythrocytes. In the pre-clinical acute toxicity trial, the IM-15 (300 or 2000 mg/kg, i.p.) induced a depressant effect on the Central Nervous System (CNS) and its LD50 (lethal dose 50%) was estimated at around 1000 mg/kg. The hydantoin derivative (12,5; 25 and 50 mg/kg, i.p.) reduced (p<0,001) all parameters (tumor volume and mass, and cell feasibility) in Ehrlich's ascitic carcinoma model, which characterizes its antitumor potential. It was observed that IM-15 did not interfere in the distribution of cells during the cell cycle. However, data showed that IM-15 reduced the peritumor vascular microvessel (p<0,05), cytokine levels IL4, TNFα, IFN-y, and chemokine CCl-2 (p<0,001). This suggests that the antitumor potential of such imidazolidine derivative involves the immune response modulation in connection to the control of cell proliferation, apoptosis and angiogenesis. Furthermore, the results suggest the angiogenesis reduction that was observed post-treatment with IM-15 is associated with the reduction of CCL2, TNF-α and IL-4, cytokines known as proangiogenic. Toxicological analysis indicate that the nine day treatment with the hydantoin derivative did not induce alterations in the biochemical and hematological parameters upon this study. In respect of the micronucleus trial, IM-15 (50 mg/kg, i.p.) did not induce the increase of the amount of micronucleated erythrocytes, thus, indicating low genotoxicity. IM-15 (50 mg/kg, i.p.) revealed antinociceptive activity in the hot plate, abdominal contortion and formalin trials, in which the last one had a stronger effect on the second phase, suggesting action in the inflammatory pain. It was shown that the mechanism of action involves neither the opioid's nor the GABAergic's pathways. Although, it does involve nitric oxide participation in the first phase of the formalin trial. IM-15 induced an antiedematogenic effect, but it did not minimize the peritonitis induced by carrageenan. Therefore, it is possible to infer that the IM-15 shows low toxicity and antitumor, antinociceptive and antiedematogenic activity.

This study was to analyze the relations between contingency factors and the use of management tools within the hotel chain. To reach the proposed objective realized, a descriptive, exploratory and quantitative research. The universe understood all 106 companies listed in the registry of the Municipal Secretariat of Tourism of the city of João Pessoa, of which 98 accepted to participate in this research. Data collection was performed through face-to-face interviews with the manager of the management sector, in July and August 2018. Statistical procedures related to descriptive statistics and Spearman's correlation were performed using the STATISTICA system. The most commonly used traditional management artifacts on budget, budget analysis and traditional costing techniques were obtained as preponderant results. In relation to the modern management tools, the frequency of use of the artifacts on life cycle analysis and just in time for decision making in the long term was emphasized. It has been realized that a managerial artifact used in one organization may not have the same success in another. The investigated companies pointed out as very important the contingency factors related to competence for labor, to customer satisfaction, to invest in technological innovation, to use integral software, to ecommerce as an effective way to sell the lodging and to cherish high quality in the provision of services. When correlating the statistical significance of the relationships between the contingency factors: environment and the use of modern artifacts, there were low correlation indices presenting negatively activity-based costing and competition attitudes. It is also worth noting that in the scope of the companies participating in the research, there was flexibility to change or improve the managerial tools used, without resistance to change, which is a positive point.

The analysis of municipal financial equilibrium is important to identify the capacity of local governments to offer and maintain the continuity of goods and services to society, as well as to anticipate financial tensions, preventing the crisis from settling. In this sense, it seeks to control financial equilibrium and prevent collapse by maintaining sufficient levels of internal resources to meet its current obligations. Thus, this research aimed to identify the determinant factors of the level of internal resources of the Brazilian municipalities in the period from 2007 to 2017. The analysis undertaken was composed by all Brazilian municipalities, being adopted as a research method a linear regression model using fixed-effects panel data. The results indicated that among the determinant factors of the level of internal resources in Brazilian municipalities are the dependence on fiscal transfer, the level of unemployment associated with a high degree of dependent population, the level of indebtedness of the entities in the face of the need to make financial contributions to amortize the contracted debts that negatively have impacted the level of internal resources of the municipalities. In a transversal way, it was evidenced that the indebtedness has a statistical relationship with the economic crisis, which affects more directly the levels of internal resources. Finally, the factors that have a positive influence on the level of internal resources were the population's income, the educational level of the population that produces higher levels of labor force and, consequently, enhances the levels of internal resources through the capacity of the government in obtaining its own revenues. Electoral and crisis periods alone were not statistically significant in the empirical model of the research.

The goats subclinical mastitis causes economic losses due to disposal, spending on therapeutic measures and reducing the quantity and quality of milk and its derivatives. This study aimed to determine the incidence, etiology of subclinical mastitis and identify coagulase negative Staphylococcus (CNS) by PCR and identify the presence of ECN methicillin resistant or biofilm production beyond, note the risk factors associated with infection. In this study, 372 samples of goat milk fresh from 186 animals from 10 dairy farms in the state of Paraiba, were evaluated by testing the screened mug, California Mastitis Test (CMT) and bacteriological examination. After the results of the microbiological, the 24 milk samples showed that Staphylococcus coagulase negative were sent to the molecular biology laboratory of the Embrapa Coastal Tablelands for DNA extraction directly from milk. The fragments containing the genes of interest were amplified from genomic DNA isolated strains by PCR using primers specific for the amplification of genes in study. In the test the screened mug and CMT, 3.22% and 43.90% of the samples were positive, respectively. In bacteriological examination, 19.35% for the number of glands and 38.70% of the goats were positive and the most common pathogen among pure alone or in combination was coagulase negative Staphylococcus (28.25%). Make frequent cleaning the premises, isolate sick animals, have milking parlor hygiene and ceilings before milking were the biggest risks associated with infection of the mammary gland of goats. Based on this study can further the study of the etiology of subclinical mastitis goat, allowing perform extractions directly from milk samples and presenting different types of bacteria.

Staphylococcus aureus is a major pathogen in veterinary medicine and the increasing emergence of strains resistant to different classes of antimicrobial agents elevates the need for accurate identification and monitoring of this bacterial species. This study aimed to initially evaluate the accuracy of PCR for nuc, femA and coa genes for identification of S. aureus obtained from different animal species samples. A total of 71 Staphylococcus spp. isolates were analyzed through the MALDI-TOF and were identified 12 different species. Among Staphylococcus aureus (34) the femA, nuc and coa genes were identified in 30, 26 and 16 isolates respectively. Although the specificity of the PCR for all markers tested was 100%, the sensitivity was found 88.2%, 76.5% and 46.5% for femA, nuc and coa markers, respectively. The sensitivity was 100% when used the femA and nuc markers simultaneously. The results confirm the PCR technique as a accurate for S. aureus identification and suggests the simultaneous use of femA and nuc primers. Later aimed to evaluate the antimicrobial resistance patterns and genotypic relationship between S. aureus cultured from nasal cavities of healthy horses from two geographically distant states of Brazil (Paraíba and Rio Grande do Sul). A total of 123 Staphylococcus spp. analyzed initially, 21 isolates were identified as Staphylococcus aureus by biochemical tests and PCR using species-specific markers (nuc, femA and coa). The results showed four different resistance patterns. Multidrug resistance was observed in 10 S. aureus isolates. Although none S. aureus has been found harboring mecA gene, 6 methicillin-resistant isolates were found, indicating the presence of methicillin-resistant Staphylococcus aureus (MRSA). Genotyping by Rep-PCR showed that the isolates were not grouped by geographical origin, and indicate an enormous diversity of Staphylococcus aureus strains colonizing healthy horses in Brazil.

The present work of dissertation is the result of a research that had as its central theme the contributions of popular knowledge regarding the dimension of spirituality, in a process of teacher training in the perspective of popular education. This research work arises from the concerns experienced in the process of formation of educators in the Tecelendo Extension Program at the Universidade Federal do Recôncavo da Bahia, of which I am a part since the year 2009. Treat the contributions of spirituality in the training of teachers is a big challenge. However, the contributions of popular education in Brazil bring us to an important debate regarding the dimension of spirituality in the processes of teacher training. In this sense, we developed a qualitative research with a focus on research participant. The instruments used were: 1) semi-structured interviews with 15 teachers and educators of Tecelendo; 2) participant observation of teacher training activities developed by the program; 3) analysis of documents of Tecelendo. The research revealed that the spirituality is present in the formation of educators Tecelendo from popular knowledge and of mysticism involved for them, moreover, it was possible to perceive its contribution in the process of transformation and emancipation of the educators and teachers included in the program. The theoretical reference of this work is based on studies of: Paulo Freire (1996 and 2014), João Francisco de Souza (2007), Eymard Vasconcellos (2009), Ferdinando Röhr (2013), Fritjot Capra (2014); Leonardo Boff (2006, 2008) and Frei Betto (2008). The contributions of this research work go on extension of the dialog between Popular Education and spirituality in teacher training, as well as with a probable elements for reflection and improvement of methodologies in Tecelendo Extension Program.

This doctoral thesis linked to the area of the History of Education aimed to analyze the pedagogical press of Paraiba as a space of action and teacher training in favor of the construction of pedagogical renewal ideas between 1919-1942. Our main historical sources were the Bulletin of the Society of Primary Teachers of Paraiba (1919), the newspaper O Educador (1921-1922) and the Magazine of Teaching (1932-1942). We started from the understanding that the pedagogical press was the stage used by teachers to give legitimacy and scientific theories to their ideas, seeking a space of their own performance and, at the same time, training for other subjects. It was a necessary material support for the educational renovation project. Its pages included pedagogical ideas, teaching methods, instructions, communiques, guidelines, lesson plans, lectures, photographs and graphic resources, which fostered the discussion of the knowledge that aimed to form the faculty, especially the primary school. This type of printing was an instrument of political action of the intellectual teachers who used their networks of sociability, as well as strategies and tactics to print and to make representations (ALONSO 2002, CERTEAU, 1990, CHARTIER, 1990, SIRINELLI, 2003). The proposal was clear: it was necessary to establish a renovated school in Paraiba. Laws, associations, pedagogical weeks, bulletins, newspapers and magazines fostered the changes and were analyzed in this research from the encounter between the "old" and the "new", the "traditional" and the "modern". There was no ready formula to call the educational renewal of the period, and everyone, even participants in the same group, thought differently. We can say, then, that there were several versions of the new schools defended, because the ideas were not static. On the contrary, they were in motion. Being aware of these nuances was one of our intentions. In the midst of their advice and instruction, these subjects created an intellectual field and under the sign of the new, the teachers acted and formed their professional colleagues in the pedagogical press.

The cattle is the main host for Rhipicephalus (Boophilus) microplus, is an important ectoparasite of wide propagation in tropical and subtropical regions of the world. The manipulation of acaricide chemicals is the main available method at controlling the ticks, whose main disadvantage includes increasing parasite resistance to the active principle and the possibility of the presence of residues in animal products and environmental damage. Turnera subulata Sm. popularly known as chanana is an annual herb grown in sandy soils and slopes common in Northern and Northeast of Brazil. The chanana was tested as a dry extract and also associated with a chemical acaricide. Tests were conducted in dry ticks on absorbent paper and were wet after the dry extract immersion. Homogeneous groups of triplicates were separated, containing 10 ticks, obtaining decreasing concentrations of 50%, 25%, 12.5%, 6.38% of dry extract respectively, association with the pyrethroid and distilled water as negative control. The biocarrapaticidogramas variables were evaluated according to reproductive efficiency (RE), and product efficiency (PE) according to the equations presented by Drummond et al. (1973). Throughout this study, there was no death of engorged ticks at any concentration of the treated groups. There was effectiveness of the product on the hatching of eggs of females with dry extract of Turnera subulata Sm., however, the percentage presented in all concentrations are low for the control of infestation by ticks, we suggest that the combination extract to other plant that posseses active ingredients acaricide. The interactive effect of the dry extract chanana with pyrethroid did not present acceptable efficiency according to what is stated by the Ministry of Agriculture, probably a result of the indiscriminate use of the active principle of the pyrethroid class that generated a parasite resistance.

La participación de los adultos en las instituciones de enseñanza superior ha despertado cada vez más interés tanto de investigadores, bien de la sociedad en general, haciéndola una temática pertinente a las sociedades globalizadas (Oliveira, 2007; Pereira, 2009; Pombo, 2010; Ferreira et al., 2012; Gonçalves, 2014). En este sentido, el conocimiento de las motivaciones que impulsaron a los estudiantes adultos a ingresar en la universidad (Vassoler, 2013; Quintas et al., 2014; Losada, 2015) y de las expectativas que les motivan a concluir el curso superior (Lavoura, 2011; Costa et al., 2013; Bisinoto et al., 2016) pueden contribuir a mejorar la estrategia institucional. Con el objetivo de conocer y analizar la participación de los adultos en la Universidad Federal de Paraíba / Campus I, así como las motivaciones y expectativas de ese público que ingresó en los cursos de graduación presenciales de la UFPB / Campus I con edad igual o superior a 30 años, aplicamos un cuestionario, que contenía dos escalas de tipo rating, con 194 estudiantes adultos. Los datos fueron tabulados en el programa SPSS y fueron analizados por medio de estadística descriptiva (univariada y bivariada). Después de analizados, los datos revelaron que la profundización de los conocimientos (M=4,73) es el principal factor motivacional y, que desarrollarse intelectualmente (M=4,53) se constituye en su principal expectativa. Al correlacionar los tipos de motivación con los tipos de expectativa identificamos que existe una correlación altamente positiva entre la motivación extrínseca y la expectativa profesional (r=0,80). Mientras que entre la motivación intrínseca y la expectativa personal existe una correlación positiva moderada (r=0,47). Estos resultados responden a nuestro problema de investigación, siendo la búsqueda por la profundización de los conocimientos la principal motivación que impulsaron a los estudiantes adultos a ingresar en la universidad y el deseo de desarrollarse intelectualmente les motivan a concluir el curso superior. Por lo tanto, inferimos que las principales motivaciones y expectativas de los estudiantes adultos son orden personal (intelectual).

This study aimed to evaluate effect of three different rearing systems: traditional system- TS; intensive feedlot system without concentrated – IFSWC and intensive feedlot system to concentrate- IFSTC on animal performance, carcass characteristics and meat quality of dairy goats kids. The experiment was conducted simultaneously in two properties located in the semiarid region of the state of Paraíba, Brazil, with different management systems offspring. Thirty newborns goat kids, no castrated with initial weight of 3.35 kg ± 0.65 kg crossbreed Parda Alpina x undefined breed (SPRD), distributed in a completely randomized design with three treatments and ten were used repetitions. During the experimental period, the animals were subjected to semi - intensive management with their mothers in breastfeeding and supplementation with concentrated feed and forage cactus. In both intensive systems , the kids were separated from their mothers, artificially fed cow's milk to the limit of 1.5 l/day and supplemented with hay Tifton. In both systems, the animals were slaughtered when they reached 12 kg liveweight. It was observed that the goats had lower IFSWC undergoing confinement period (67.2 days ), with a lower unit cost of production (R$ 172.81) and better carcass traits (fat thickness and finish) the than the others. Moreover,the meat obtained from animals raised in IFSWC showed paler color, more pronounced and with high dietary indicators of meat quality ( higher content of linoleic acid and higher PUFA:SFA and lower w6 : w3 ) aroma, which qualifies for high-quality beef markets.

The species Crataeva tapia L. is recommended for reforestation programs in degraded areas, however, the control of pathogens in their seeds should be studied with greater emphasis, since the pathogens make it difficult to germinate. In this sense, the search for alternative methods to control pathogens in seeds that do not affect the environment is gaining worldwide attention. Among these methods are alternative treatments, such as essential oils. The objective of this research was to evaluate the efficiency of peppermint oil Mentha arvensis L. on fungal microflora and viability of C. tapia seeds, in order to establish the control of pathogens and, consequently, to contribute for the preservation and conservation of these forest species, without damage to the environment. The seeds were collected in the cities of Cuité de Mamanguape, Umbuzeiro, Remígio, Esperança and Sousa, all in the state of Paraíba. The seeds were submitted to sanity and germination tests. The evaluation of the incidence of fungi was made from the visualization of these by means of the incubation method in paper blotter-test. 100 seeds per treatment were used in the sanity test, being distributed in ten replicates of ten seeds. Seeds treated with peppermint oil were immersed in 1 mL for five minutes, then incubated in Petri dishes. In the germination test, 100 seeds were used, four replicates of 25 seeds per treatment, distributed in paper towel with the rolls incubated in the germination chamber at a temperature between 20-30°C. The experimental design was a completely randomized 2x10 factorial design. In the seeds of C. tapia the fungi Aspergillus sp., Aspergillus niger, Botryodiplodia sp., Botrytis sp., Colletotrichum sp., Cladosporium sp., Fusarium sp., Monilia sp., Periconia sp., Penicillium sp. and Rhizopus sp. Therefore, the use of essential oils in fungal management in C. tapia seeds appears as a promising alternative.
