title: Analysis of the long-term effects of groundwater extraction on the water balance in part of the Urucuia Aquifer System in Bahia - Brazil

description: Abstract In agricultural regions where there is insufficient rainwater for cultivation, understanding the dynamics of surface water and groundwater is critical to assess the impact of increased well pumping on the water balance. The western region of the state of Bahia-Brazil, the largest area of agribusiness in the state, has experienced progressive occupation since the 1980s, resulting in pressure on water resources - mainly after the introduction of irrigation - and conflicts among water users. This study analyzed the effects of groundwater extraction by wells in a portion of the Urucuia Aquifer System. The methodology used was the simulation of groundwater flow in steady-state for three scenarios: i) without withdrawal of water by pumping wells; (ii) with current withdrawal rates; and (iii) with 60% additional extraction. After defining well production rates from field surveys (4.6 m3 s-1) and modeling of the aquifer base geometry (maximum thickness of 535 m), the steady-state models with and without pumping show that, in the long term, groundwater storage decreases by 2 km3 (0.8 m on average in the aquifer) without interference in the regional flow direction. The mass balance shows that the base flow of the main rivers is reduced by approximately 6% after current groundwater extraction and an additional 2.5% after additional extraction. The results point to a greater impact on surface water caused by a reduction in groundwater storage and related river base flow. This indicates the importance of maintaining and expanding the groundwater-level monitoring network.

title: Values of University Students Portugal/Brazil: socio-political dimension

description: ABSTRACT: This study assesses the socio-political values of colleges students (n = 605) Portugal/Brazil, employing a questionnaire on socio-political dimension Values. The results revealed significate differences about fundamental values. We find indifference/scepticism in Portuguese and Brazilian students practice, essentially with regard to the causes of social inequalities. In Brazil are connect from bad luck, laziness and inactivity and in Portugal a short instruction distinguish. This research empowers the implementation of programmes of education for citizenship in academic context.

title: Emerging Contaminants in Trans-American Waters

description: Abstract Industrial development has made new products available to people to make their lives easier. Items such as food, cleaning, personal care and health products, among others, are processed, sold and consumed daily by all age groups. These products include in their formulation inorganic and organic chemicals with the purpose of improving or increasing some of their properties, making them more attractive to the consumer. These substances are strictly controlled during production so that the final product may be safely consumed. In most cases, the constituents of commercial products end up in wastewater, where they are not controlled. These uncontrolled pollutants of differing chemical natures are known as “Emerging Contaminants” (ECs). Research worldwide has found ECs in various environmental matrices, especially water. To understand this problem, four fundamental aspects must be addressed: 1) the analytical methods for its determination; 2) the occurrence in environmental matrices; 3) the treatments for the removal of ECs in wastewater and drinking water plants; and 4) the risks to health and the environment. This document reviews these four aspects with regard to 14 ECs commonly found in the studies around the world and addresses the state of these ECs in trans-American waters.

title: Methodological and Analytical Dimensions of University Extension

description: ABSTRACT: The aim of this article is to present and discuss a methodological proposal to research university extension. This proposal was withdrawn from a historical and conceptual study about the conceptions and practices of extension. A series of methodological dimensions were removed: one who extends; to whom it is intended; what activities materialize it; what kind of knowledge is extended and what are the objectives of this process; because the extension is made; impacts of extension activity; how activities are legitimized; contextual and historical insertion; and the debate about the university’s social function and commitment.

title: Processes of Afrobetization and Literacy of (Re)Existences in the Education of Young and Adult

description: ABSTRACT: The paper discusses the themes of education and teaching-learning processes throughout life, taking as a cutout, racial relations in the contexts of Youth and Adult Education (EJA) in Brazil, considering what determines Law 10,639/03. This is an exploratory-descriptive study, with a mixed approach that associates the analysis of indicators, bibliographic research and the document al., as well as data from two experiences in the EJA. The results reveal that the EJA because it is constituted mainly by blacks and blacks, can be understood as an affirmative action, which seeks to correct distortions and repair historical injustices. It points out as a pedagogical proposal for teaching and meaningful learning the association between afrobetization and literacies of (re) existences.

title: School Management in Feira de Santana: analysis of official texts

description: ASBTRACT: In the 21st century, the need for regulation of the manager’s role is incorporated into the discourse of school management. The documental research carried out included the analysis of official documents from Feira de Santana - Bahia, Brazil between 1990 and 2015, applying the Policy Cycle as the methodological approach. The results showed that the predominant management model emerges from the interrelationships between school, local authorities, national context and production of official documents. The election of principals, in order to provide the management function, revealed evidence for the understanding of the democratic management model in Feira de Santana, influenced by the participation of both teaching movements and the local population.

title: Intermediate Representations in the Learning of Combinatorial Situations

description: ABSTRACT: The article analyses identification, conversion and treatment of registers in combinatorial situations. Two studies were carried out: 1) identification of conversions and 2) with intermediate representations between registers in natural language and in numerical expression. Hypotheses of greater difficulties in the combination situation and in the conversion to numerical expression were confirmed. Intermediate representations (tree of possibilities or systematized listing) for the teaching of Combinatorics were indicated, however, working with trees resulted in better performance - because they have more congruence with numerical expressions. It is recommended, therefore, the intermediation of representations in the identification, conversion and treatment of combinatorial situations.

title: Comparison of two esters estradiol as inductors on ovulation follicular diameter and pregnancy rate of dairy cattle subject to program of FTAI

description: SUMMARY This study aimed to evaluate the effect of using two estradiol esters, on the diameter of the ovulatory follicle (DFOL), and pregnancy rates of dairy cows submitted to FTAI program. Therefore, 94 females crossbred Dutch-Gir were subjected to the following hormone protocol started on a random day D0, by insertion of an intravaginal device of progesterone (P4) associated to 2.0 mg of estradiol benzoate (EB) intramuscular (im). In D8, the devices were removed and 500 µg of sodium cloprostenol – prostaglandin – F2α was administered and 300 IU of equine chorionic gonadotropin (eCG) i.m. At this time the animals were divided in two groups: 50 cows were allocated to EC group and received 1 mg of estradiol cypionate i.m., while the other 44 received 1.0 mg of EB i.m. 24 hours after removal of the devices (D9), being called the BE Group. At D10, inseminations were carried out, and prior to each IA procedure were performed trans rectal ultrasonography to measure the DFOL. Pregnancy diagnosis was performed 55 days after the FTAI. There was no significant difference between measurement of DFOL found for the BE and CE groups being, respectively, 11.45 ± 2.34 and 10.71 ± 2,43mm. The BE group also showed a 34.10% pregnancy rate, similar to the EC group which was 40.00%. It is concluded that CE can replace the BE in TAI protocol in dairy cows, representing an alternative to simplify the FTAI protocol.

title: Model for assessment of teaching-service integration in Teaching Service Units in Primary Care

description: ABSTRACT This research aimed to develop a model for evaluating the effectiveness of the teaching-service integration in Primary Health Care. The model was based on literature, consult with the actors involved in the integration (management, service community and education) and consensus techniques with discussion of experts for validation. The theoretical-logical model was built with support in health and education legislation. The proposed evaluative matrix is composed of four dimensions and ten indicators. Posteriorly, the proposed model will be used to verify its applicability, the need for adjustment and the possibility of replication in different contexts.

title: Effects of drying and storage conditions on the stability of TSH in blood spots

description: ABSTRACT Objective To evaluate the influence of sample drying and storage temperature on TSH stability in neonatal screening. Subjects and methods Blood samples from 29 adult volunteers as a surrogate for neonatal blood (10 with normal TSH, 9 with overt hypothyroid and 10 with subclinical hypothyroidism) were spotted on filter paper and dried at 22°C or 35°C for 3 hours. The samples were then stored at 22°C, -4°C, or -20°C, and TSH measurements were performed at day 0 (D0), D7, D30, D60, D180, and D360 of storage. Results The drying temperature did not interfere with TSH measurement on D0. TSH values remained stable up to D30 when stored at 22°C and were stable up to D60 when stored in a refrigerator or freezer. Samples stored at 22°C had a greater decrease in TSH values than samples stored in a refrigerator or a freezer. Conclusions Freezer storage is not advantageous compared to storage in the refrigerator. At the end of one year, if confirmation of the initial result is required, a reduction of TSH concentrations should be taken into account.

title: Evaluation of oral conditions in patients with neurodegenerative diseases treated in geriatric centers

description: ABSTRACT Objective: To compare the general clinical conditions and oral alterations, and also evaluate the prosthesis, in subjects diagnosed with Alzheimer's disease (AD) or Parkinson's disease (PD), attended at two geriatric centers in the city of Fortaleza - Ceará. Methods: 70 patients were analyzed (between 57 to 91 years) with AD and PD, through evaluation of neurological medical records and oral clinical examination. Variables as sex, age, race, comorbidities, oral manifestations and prosthetic conditions were observed. A total of 20 elderly patients without neurological disease consisted the control group (CG). Fisher's exact test and Kruskal-Wallis were used as statistical analysis. Results: In both groups, blood hypertension was the most frequent comorbidity. As for the oral examination in the group with AD, it was observed that 54.2% had periodontal disease, 34.2% caries. Similar results were found in PD patients (31.4%; 22.8% - respectively). However, no difference was observed between the groups, as the systemic and oral manifestations in both geriatric centers (p&gt; 0.05). Was identified more than half of the subjects (57.7%) using dentures, and 86.5% of these had become maladaptive, with some kind of defect. There was statistical difference in the presence of associated oral pathology, denture stomatitis, between dementia and control group (p = 0.0213). Conclusion: Elderly patients with AD and PD have poor oral health, as well as those without neurodegenerative diseases. However, have more defects and disorders associated with the use of removable dentures.
