title: Evaluation of the Use of Fly Ash as a Low Cost Technology for Phosphorus Removal in Wastewater Treatment

description: Abstract “Pozzolan” is a slag from the burning of coal in power plants which has the potential to assist as a low-cost adsorbent for wastewater treatment. The excess of Phosphorus (P) in the environment can promote chemical pollution and harm ecosystems, especially water. It is therefore necessary to implement inexpensive techniques and processes for the efficient treatment of water and wastewater. In this context, this study evaluated the use of the pozzolanic fly ash material for P removal from wastewater for the development of low-cost treatment technologies for environmental restoration and remediation of water resources. The treatment systems were developed in batch configuration. The removal tests from a synthetic sample with a known concentration of P reached a maximum of 30% removal in concentration, even varying the pH and performing different treatments of the pozzolanic material. This low removal efficiency of Phosphorus led to a comparative test between different lots of pozzolan in order to verify if the results obtained were characteristic of the material itself or of the lot obtained. Also the P adsorption isotherms were constructed with the two lots achieving adsorption capacities from 0.87 mg g-1 to 74 mg g-1. This difference indicates that the low P removal efficiency in the preliminary tests is due to the characteristics of the substrate of the first lot. Tests on a real effluent using the pozzolan from the second sample lot indicated a 99% efficiency of P removal, with an initial concentration of Phosphorus in the effluent of 5.5 mg L-1.

title: Substernal goiter and laryngopharyngeal reflux

description: ABSTRACT Objective This study aims to compare the prevalence of laryngopharyngeal reflux signs between two groups of patients undergoing thyroidectomy for voluminous goiter: substernal goiters and voluminous cervical goiter without thoracic extension. Subjects and methods A retrospective case-control study was performed with data retrieved of the charts of the patients submitted to thyroidectomies occurred at a tertiary care center (Head and Neck Surgery Department, University of São Paulo Medical School) between 2010 and 2014. The selected thyroidectomies were allocated in two groups for study: patients with substernal goiters and patients with voluminous cervical goiter without thoracic extension. Cervical goiters were selected by ultrasonography mensuration. Clinical criterion was used to define substernal goiter. Results The average thyroid volume in patients with substernal goiter was significantly greater than the average volume in patients with only cervical goiter (p &lt; 0.001). The prevalence of signs of reflux laryngitis at laryngoscopy was significantly greater in substernal goiter patients (p = 0.036). Moreover, substernal goiter was considered as the unique independent variable for high reflux laryngitis signs at laryngoscopy (OR = 2.75; CI95%: 1.05-7.20; p = 0.039) when compared to only cervical goiter patients. Conclusion This study shows a significant association between substernal goiters and signs of laryngopharyngeal reflux at preoperative laryngoscopy. Therefore, when compared with voluminous cervical goiters, the substernal goiters increase the chance of reflux laryngitis signs in patients.

title: Correlation between parameters of self-monitoring of blood glucose and the perception of health-related quality of life in patients with type 1 diabetes mellitus

description: ABSTRACT Objective The aim of this study was to evaluate how different parameters of short-term glycemic control would correlate with the perception of health-related quality of life (HRQoL) in patients with type 1 diabetes mellitus (T1D). Subjects and methods A total of 50 T1D patients aged 18 to 50 years were evaluated with the questionnaires Problem Areas in Diabetes (PAID) scale and Diabetes Quality of Life (DQOL) measure after 30 days of self-monitoring of blood glucose (SMBG). Glycemic control was evaluated using glycated hemoglobin (HbA1c), mean glucose levels (MGL) in the prior month’s data from SMBG (Accu-Check 360o), number of hypoglycemic episodes (&lt; 70 mg/dL and &lt; 50 mg/dL), and glycemic variability (GV). Results PAID correlated positively with MGL (r = 0.52; p &lt; 0.001) and HbA1c (r = 0.36; p &lt; 0.0097), but not with GV (r = 0.17; p = 0.23) or number of hypoglycemic episodes (r = 0.15; p = 0.17 for glucose &lt; 70 mg/dL and r = 0.02; p = 0.85 for glucose &lt; 50 mg/dL). After multiple linear regression, only MGL remained independently related to PAID scores. DQOL scores had a positive correlation with MGL (r = 0.45; p = 0.001), but not with HbA1c (r = 0.23; p = 0.09), GV (r = 0.20; p = 0.16), or number of hypoglycemic episodes (r = 0.06 p = 0.68). Conclusion In T1D patients, MGL, but not HbA1c or number hypoglycemic episodes, was the glycemic control parameter that best correlated with short-term perception of HRQoL.

title: Altitude and soils determines abrupt variation of vegetation in altitudinal gradient in Atlantic Rain Forest

description: Abstract The variation of vegetation in altitudinal gradients is usually conditioned by the thermal gradient. We hypothesized that the vegetation structure varies abruptly as a result of very distinct environments whose formation is not only related to altitude and climate. We selected three areas in the Morro do Baú, in Ilhota municipality, Southern Brazil. In each, we allocated 50 plots of 100 m2 (Area 1 - 340 m a.s.l., Area 2 - 540 m a.s.l. and Area 3 - 810 m a.s.l.). We measured all individuals with DBH ≥ 4,77 cm. We elaborated a Venn diagram and compare areas using rarefaction curves. We applied DCA and NMDS ordination to identify the degree of vegetation variation. Because of its strong distinction, we compared Area 3 with part of the data from IFFSC. The vegetation structure varies abruptly between Areas 1/2 and 3, the latter being a true cloud forest determined by the joint effects of altitude, climate, soils and geomorphology. Regionally, however, the similarities are not greater with other cloud forests, but with areas near and of approximately the same altitude.

title: Literacies in Portuguese and English in Brazilian Higher Education: Landmarks and Perspectives

description: Abstract This project aims at contributing to the project called Initiatives of reading and writing in Higher Education (ILEES) in Latin America, whose objective was to identify and describe the initiatives of teaching and research in reading and writing in higher education in Brazil. In this article, we aim at covering the second stage of the research by identifying the writing centers and analyzing the interviews with the researchers mostly cited as references or those considered responsible for gathering research groups and/or literacy projects in different state and federal universities in the country. For our analyses, we use Bronckart's (2008) and Bulea's (2010) methodological framework in order to recognize, in the interviews, the themes (thematic organization segment - SOT) and how the interviewees (E) develop such themes in their discourse through the thematic treatment segments (STT). The results show five writing centers regarding academic reading and writing in the national context. The interviews emphasize theoretical frameworks towards literacy and recognize the lack of initiatives in different Brazilian universities and, regarding sustainability, enlargement, strengthening and recognition are urgent needs, according to our interviewees.

title: The use of information technology and communication (ICT) for the South American immigrants in Argentina and the shaping of transnational social networks

description: Abstract The use of ICT implies a turning point for traditional migration processes because enable the uprooted migrant become a connected migrant. The ICT, especially the Internet, creates a lush universe of possibilities of connection and communication with the countries of origin, with the diaspora and with the community of arrival amending the construction of migrant subjectivity and form and transnational social networks. In this article, we plan to see the relevance of ICT, beyond the conception of tools and cultural artifacts of the public sphere, as devices that migrants turn to build as a referential space, which supports the conservation of regulars links, social networks at origin and mitigate or reconfigure the nostalgia of the absence and return. Through conducting interviews and questionnaires, We intend to study the means and technologies often used by individuals of these groups to communicate with their social networks of origen, the causes of their choice, their frequently uses and the subjects that arouse them their interest when resorting to these technological devices.

title: Nutritional divergence of peels pods of lima bean genotypes for ruminants feeding

description: AbstractThis research aimed to evaluate the nutritional divergence of twenty-five genotypes of peel pods of lima bean for ruminant feeding, based on chemical composition as well as fermentation and in situ degradation kinetic characteristics. The chemical constituents were considered discriminatory variables in the first analysis, while the parameters of rumen degradation kinetics and effective degradability (ED 2%h-1) of dry matter were considered in the second analysis. Was adopted the cluster analysis according to the Tocher optimization approach, considering the average Euclidian distance matrix of characters to evaluate the dissimilarity among the genotypes. It was verified the formation of seven heterogeneous groups, highlighting the acid detergent fiber (ADF) and crude protein (CP) as most impactful variables for grouping in the first analysis, contributing with 41.7 and 29.3%, respectively, while in the second analysis, the soluble fraction degradation rate accounted for 38.7 and 28.0%, respectively. The chemical constituents CP and ADF and the kinetic parameters of ruminal degradation soluble fraction (fraction a), degradation rate (c) and potentially degradable fraction (fraction b) of the DM, are efficient to identify the nutritional divergence of pod shells lima bean genotypes based on multivariate analysis. Considering the parameters adopted to form a pool by Tocher´s method, the lima bean genotype 123, present efficient effective degradation and degradation rate compatible with the tropical forage, and better nutritive value and forage potential than pod shells of the other lima bean genotypes.

title: Analysis of prototypical narratives produced by aphasic individuals and cognitively healthy subjects

description: Aphasia can globally or selectively affect comprehension and production of verbal and written language. Discourse analysis can aid language assessment and diagnosis. Objective: [1] To explore narratives that produce a number of valid indicators for diagnosing aphasia in speakers of Brazilian Portuguese. [2] To analyze the macrostructural aspects of the discourse of normal individuals. [3] To analyze the macrostructural aspects of the discourse of aphasic individuals. Methods: The macrostructural aspects of three narratives produced by aphasic individuals and cognitively healthy subjects were analyzed. Results: A total of 30 volunteers were examined comprising 10 aphasic individuals (AG) and 20 healthy controls (CG). The CG included 5 males. The CG had a mean age of 38.9 years (SD=15.61) and mean schooling of 13 years (SD=2.67) whereas the AG had a mean age of 51.7 years (SD=17.3) and mean schooling of 9.1 years (SD=3.69). Participants were asked to narrate three fairy tales as a basis for analyzing the macrostructure of discourse. Comparison of the three narratives revealed no statistically significant difference in number of propositions produced by the groups. A significant negative correlation was found between age and number of propositions produced. Also, statistically significant differences were observed in the number of propositions produced by the individuals in the CG and the AG for the three tales. Conclusion: It was concluded that the three tales are applicable for discourse assessment, containing a similar number of propositions and differentiating aphasic individuals and cognitively healthy subjects based on analysis of the macrostructure of discourse.

title: Growth of corn plants in soil containing tannery sludge vermicompost and irrigated with sewage wastewater

description: This study evaluated the parameters of the growth of corn plants (Zea mays L.) grown in pots containing soil plus tannery sludge vermicompost and irrigated with household wastewater. The arrangement of treatments consisted of a factorial 2x6 (two types of irrigation and six fertilization treatments) in a completely randomized design (CRD) with five repetitions. The height of the plants and the diameter of the stems were evaluated bi-weekly. The results indicated that both the wastewater and the tannery sludge vermicompost are good sources of nutrients for the plants, promoting their growth. We conclude, therefore, that wastewater from households and tannery sludge vermicompost can be considered an agricultural waste of interest for the corn crop.

title: Cognitive performance and engagement in physical, social and intellectual activities in older adults: The FIBRA study

description: Cognitive decline in aging can negatively impact quality of life in the elderly. However, studies have shown that elderly engaged in advanced activities of daily living (AADLs) can maintain or enhance global cognitive function or specific domains. Objective: To investigate the relationship between engagement in AADLs and domains of cognition in elderly from seven different locations in Brazil. Methods: A cross-sectional study involving 2,549 elderly without cognitive deficits suggestive of dementia was conducted. Data were collected on sociodemographic characteristics, health status, the Mini-Mental State Exam (MMSE) by subdomain (orientation, memory, attention/calculus, language and constructional praxis), and engagement in AADL grouped under physical, social and intellectual activities. Results: Multivariate linear regression analysis revealed an association, albeit modest, between intellectual AADLs and the domains orientation, attention/calculus, language and constructional praxis (R2=0.005, 0.008, 0.021, and 0.021 respectively). Social AADLs were correlated with memory (R2=0.002) and language (R2=0.004) domains. No association was found between physical AADLs and MMSE domains. Schooling and family income were the sociodemographic variables exhibiting the strongest relationship with cognitive domains. Conclusion: The study found associations between intellectual and social AADLs with higher cognitive performance, suggesting that active aging can provide opportunities to attenuate cognitive decline in aging.
