Abstract: seasonal and nyctemeral variations of the phytoplankton and hydrological parameters were studied at a fixed station (00o46'37.2"s-046o43'24.5"w) situated in canela island (bragan?a-pará) in september and december, 2004 and in march and june, 2005. subsurface water samples were taken for qualitative and quantitative phytoplankton studies and to determine chlorophyll a concentrations. simultaneously physical and chemical parameters were measured: salinity, temperature, ph, dissolved oxygen and percent of oxygen saturation. a total of 64 taxa belonging to cyanophyta (one taxon), bacillariophyta (54 taxa) and dinophyta (nine taxa) were identified. chlorophyll a concentrations ranged from 4.67 mg m-3 (dry season), to 5.44 mg m-3 (rainy season) and follow phytoplankton densities, which were higher during the rainy period (mean values of 1,870 x 103 cell l-1). phytoflagellates quantitatively dominated the local phytoplanktonic community followed by diatoms. dimeregramma minor and skeletonema sp. were abundant and very frequent species over the studied period. resuspension processes originated by the strong winds and waves in the surf zone favored the dominance of d. minor during the dry period. in the rainy period, high rainfall, moderate winds as well as the influence of estuarine waters from tapera?u and caeté propitiated the decrease of salinity and the development of other phytoplankton species.

Abstract: seasonal and nyctemeral variations of the microphytoplankton were studied at a fixed station (00o46'37.2''s-046o43'24.5''w) on canela island (north brazil) in september and december/2004 (dry season) and in march and june/2005 (rainy season). samples for qualitative phytoplankton studies were obtained by filtering 400 l of surface water in the surf zone of the island through plankton nets (65 μm mesh size). field work was carried out during spring tides and samples were collected every 3 hours during a 24-hour period. the collected material was fixed in neutral formaldehyde at 4%. simultaneously, salinity of the water surface was also measured. salinity showed significant variation throughout the study period, ranging from 26.1 (june/2005) to 39.0 (december/2004), characterizing the environment as euhaline-polyhaline. a total of 130 taxa were identified, belonging to cyanophyta (two taxa), bacillariophyta (115 taxa) and dinophyta (13 taxa). diatoms were the dominant group of microphytoplankton at canela island. asterionellopsis glacialis, dimeregramma minor, skeletonema sp. and thalassiosira subtilis were the most frequent and abundant taxa. high salinities favored the occurrence of polyhalobous neritic marine species. resuspension processes caused by wind and wave surf zone were responsible for exchange between planktonic and ticoplanktonic populations, including species such as dimeregramma minor, triceratium biquadratum and t. pentacrinus which represented new occurrences for the amazon coast.

Abstract: intraseasonal oscillations are factors controlling the interannual variability of tropical rainfall. the knowledge of how numerical models reproduce its variability is important to better understand their roles and support operations of weather and climate. this paper investigates the sensitivity of a downscaling dynamic precipitation model in predicting the intraseasonal oscillations observed in the northern sector of northeast brazil (snneb - 45°w-37ow and 2os-12°s) during the period from 1974 to 2000. the results showed that rainfall was simulated on snneb explained more than 70% of the variability of rainfall observed in the quarter february to april in this region. statistical of averages, standard deviations and percent this quarter, in this region in years of climatic contrasts in the oceans pacific and atlantic tropical were also well captured by the precipitation simulated by downscaling. spectral analysis with the use of wavelets showed that dynamic downscaling has the potential to reproduce observed spectral peaks of precipitation in snneb scales up to 8 days and the scales between 64 and 128 days for the period january 1 to june 30.

Abstract: historically, educational counseling is one of the activities carried out by pedagogues. this professional goes by varied denominations and performs equally varied activities in different schools and in the different states of brazil. such diversity deprives pedagogues of the characteristics and the true dimension of their professional tasks and creates a conflict with the various roles played by different education professionals. this paper maps the presence of pedagogues in brazilian public schools and discusses the specificity of the educational counselor's work critically. it also shows the need of pedagogues in all brazilian schools.

Sabrina da Costa Silva Andrade, Eliane Teixeira Mársico, Ronoel Luiz de Oliveira Godoy, Sidney Pacheco, Robson Maia Franco, Sérgio Borges Mano, Carlos Adam Conte-Junior
Food and Nutrition Sciences (FNS) , 2014, DOI: 10.4236/fns.2014.511114
Abstract: The present study was conducted aiming at establishing chemical quality parameters to assess ice stored mullet (0 ± 1) through the evaluation of nucleotide (adenosine monophosphate [AMP], inosine [HxR] and hypoxanthine [Hx]) degradation, biogenic amine (histamine [HI], putrescine [PU], cadaverine [CA] and tyramine [TI]) quantification and mesophilic and psychrotrophic bacteria count monitoring. The microbial load of 7 log CFU·g1 established as maximum acceptable limit was attained after the 20th day of ice storage. IMP concentration declined during the storage period to levels below the detection limit. HxR content increased only up to time T3 and then declined. Hx level increased during all the storage period. CA and HI content increase was not observed, on the other hand, PU and TI contents significantly increased (p < 0.05) at time T5. We concluded that IMP and Hx concentrations can be adequate parameters to assess mullet quality under the study conditions. HxR proved to be adequate to evaluate the freshness of mullet in the first days of storage while the amines, PU and TI, can be used to assess loss of quality. Mullet obtained in conditions similar to those of the present study and maintained at 0 ± 1can be consumed up to the 20th storage day.

Creative Education (CE) , 2017, DOI: 10.4236/ce.2017.86069
Abstract: This work is a due to a case study conducted in three schools, two public elementary and high school and in a Educational Cooperative, in two medium-sized cities of Sao Paulo, Brazil, and of our actions in the field of didactics. It aimed to understand the importance of participation of pupils and students in Student’s Unions, for discussion agenda of motivation on gender issues, citizenship and didactics. It was developed along the lines of a qualitative research, by observing the meetings, the electoral process and the actions they undertake in schools, interviews with its members, in addition to analyzing the various school plans. The literature on the subject shows that the student movements were predominantly university movements and that the students, especially high school students, always have been seen as a threat to educational institutions, and rarely as subjects, men in women in formation, required for projects of school and to citizenship. In general, the student participation bothered and was curtailed by educational administrators even in times when legislation and educational policies encouraged. It was observed that there is interest on the part of students to participate, whether boys or girls. Meetings are moments of dialogue among all without distinction of sex. The election campaign, from the preparation of the work proposals to the presentation of it to set off the two school communities, constitutes it like important moments of learning and incorporation of a democratic culture. In schools, most members of the Unions was composed of young men; however, it was found that there has been a growing interest in girls of assuming the presidency of this organiza-tion. In the educational cooperative, at the time of the survey, although there were school director’s interests for the creation of the Union, it was not possible to achieve necessary motivation not even students for the creation of the or-ganization. The depositions showed that political participation through the Student’s Unions constitutes an important element for democratic learning, for participation in school projects, centrally at all stages of the political pedagogi-cal project, and exercise of the citizenship for both sexes.

Tania Antonelli Marcelino Brabo, Rosane Michelli de Castro, José Carlos Miguel
Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.617194
Abstract: In this article, we present some notes on three distinct themes, but whose understanding requires an interdisciplinary analysis considering presenting aspects that intertwine and feature dependent ways from each other. Thus, the introduction presents the world of work aspects in our society, seeking to situate the important participation of all its processes, including women, through training processes of the production of knowledge on education. Then, we present a reflection on the work of women, double work shift and the division of labor between the sexes. Finally, we discuss some historical aspects about the woman in the teacher profession in Brazil.
