Abstract: the objective of this study was to analyze the social factors of the daily life that most influence the food habits of obese individuals, using a qualitative approach. participants were 11 obese patients attended at the nutrition clinics of a public hospital in the city of jo？o pessoa, paraíba, brazil. semi-structured and recorded interviews were held for content analysis. it was observed that the categories that stood out in the interviews were negative self-image, discrimination, anxiety and guilt feeling. when becoming obese, individuals create a negative self-image that causes anxiety and depression, among other factors, which may lead them to a guilt feeling, reinforced by social discrimination that instead of helping them losing weight, seems to encourage them to eat more.

Abstract: purpose: to identify the nomenclature for reporting cervical cytological diagnoses used by laboratories which render services to the brazilian unified health system (sus) and which participate in external quality monitoring (meq). to evaluate the information acquired from gynecologists of the sus regarding the various diagnostic classifications that they receive in the cervical cytology diagnostic reports. methods: we evaluated 94 cytology reports issued by laboratories which participate in the meq in the state of s？o paulo, brazil, and 126 questionnaires applied to gynecologists who work for the sus. results: out of the 94 laboratories, 81 (86.2%) use one diagnostic classification: 79 (97.6%) use the brazilian nomenclature for cytological reports (nblc), 1 (1.2%) uses the papanicolaou classification and 1 (1.2%) uses the richart diagnostic classification. of the 13 (13.8%) laboratories that use more than one classification, 5 use 2 types and 8 use 3 to 4 types, with 9 including the papanicolau diagnostic classification. the study showed that 52 (55.3%) laboratories presented more than one descriptive diagnosis in the same report. out of the 126 gynecologists who filled out a questionnaire evaluating the cytopathology reports, 78 (61.9 %) stated that they received laboratory reports with only one diagnostic classification, 48 (38.1%) received reports with more than one classification and 2 received reports with all 4 classifications. among the 93 (73.8%) gynecologists who prefer only one classification, 56 (60.2%) claimed that the nblc contributes to clinical practice, 13 (14.0%) opted for the richart classification, 8 (8.6%) for the reagan classification and 16 (17.2%) for the papanicolaou classification. out of 33 (26.2%) gynecologists who prefer more than one classification, 5 opted for the 4 classifications. conclusions: these data suggest that there is still resistance on the part of pathologists about using the official nomenclature in cytology reports for sus

Abstract: this study had the purpose of testing the validity of an indirect method to assess zygosity in twin studies in the portuguese population. the sample included 96 twins (45 monozygotic and dizygotic twin groups), of both sexes, from 6 to 12 yrs old, and their biological mothers, summing 141 subjects. two methods were used to determine zygosity: (1) indirectly, through peeters et al. (1998) questionnaire filled out by the mothers; (2) directly, through blood sampling of each twin member, and their dna was analysed in the laboratory. proportion of correct classification of twins as monozygotic or dizygotic through peeters et al. (1998) questionnaire was 97,8%. the qui-square test was highly significant (c2=41.053, p<0.0001), and it was reinforced by mcnemar test (p<0.0001). the results allow us to conclude that peeters et al. (1998) questionnaire shows transcultural validity to assess zygosity in twin studies in the portuguese population.

Abstract: In this paper we present combinatorial interpretations and polynomials generalizations for sequences including the Fibonacci numbers, the Pell numbers and the Jacobsthal numbers in terms of partitions. It is important to mention that results of this nature were given by Santos and Ivkovic in two papers published on the Fibonacci Quarterly, Polynomial generalizations of the Pell sequence and the Fibonacci sequence [1] and Fibonacci Numbers and Partitions [2] , and one, by Santos, on Discrete Mathematics, On the Combinatorics of Polynomial generalizations of Rogers-Ramanujan Type Identities [3]. By these results one can see that from the q-series identities important combinatorial information can be obtained by a careful study of the two variable function introduced by Andrews in Combinatorics and Ramanujan's lost notebook [4].

Abstract: Commercial multi-walled carbon nanotubes (CNT) were functionalized by oxidation with HNO3, to introduce oxygen-containing surface groups, and by thermal treatments at different temperatures for their selective removal. The obtained samples were characterized by adsorption of N2 at -196°C, temperature-programmed desorption and determination of pH at the point of zero charge. CNT/poly(vinylidene fluoride) composites were prepared using the above CNT samples, with different filler fractions up to 1 wt%. It was found that oxidation reduced composite conductivity for a given concentration, shifted the percolation threshold to higher concentrations, and had no significant effect in the dielectric response.

Abstract: objective: the objective of this study was to evaluate the impact of a diet supplemented with a bran-based cereal mixture on the nutritional status of preschool children presenting nutritional risk. methods: this was a two-month double-blinded study with a longitudinal follow up using 135 children with ages ranging from one to six years old and divided into three groups: intervention 1 (gi1=48), intervention 2 (gi2 n=45) and control (cg n=42), receiving 5g and 10g of the multi-mixture and placebo, respectively. the nutritional situation of the children in the study was evaluated before and after supplementation. results: no significant differences were observed in the weight/age, height/age and weight/height indicators at the base line (p=0.251 p=0.248 and p=0.399 respectively) between the groups studied. after intervention, the difference between the groups in the prevalence of anthropometrical deficit was also not significant (p=0.100 p=0.435 and p=0.210 respectively) and a comparison of the averages before and after intervention revealed no differences (p>0.05 using the kruskall - wallis and analysis of variance statistical methods). conclusion: in the specific case of the bran-based mixture, the impact of the small amounts of supplement ingested did not warrant expecting alterations in the recovery of children presenting nutritional risk, since these supplements contain only small amounts of calories and macro and micronutrients.
