title: Morphological characteristics and proportion of leaf blade tissues of elephant grass clones under sheep grazing

description: Abstract: The objective of this work was to characterize morphologically elephant grass (Pennisetum purpureum) genotypes and to estimate their proportions of leaf blade tissues under grazing. Two tall varieties (Elephant B and IRI-381) and three short ones (Mott, Taiwan A-146 2.37, and Taiwan A-146 2.114) were evaluated under intermittent sheep grazing as to the following morphological characteristics: plant height, internode length, and leaf blade/culm ratio. Moreover, the proportions of the following leaf blade tissues were estimated: sclerenchyma, adaxial and abaxial epidermis, bulliform cells, vascular bundles, phloem, vascular sheath, xylem, and mesophyll. The short varieties were 28.6% shorter than the tall ones and showed higher leaf blade/culm ratio; Mott and Taiwan A-146 2.114 had the shortest internodes of 3.9 and 4.7 cm, respectively, over ten grazing cycles. The clones differed regarding their proportions of leaf blade tissues, except for abaxial epidermis, phloem, and xylem. The differences in morphological characteristics indicate that the short clones Mott and Taiwan A-146 2.114 are better adapted to sheep grazing, and, therefore, may be recommended for the improvement of pastures.

title: Fluoridation of public water supply: bioethical, legal and political approach

description: Abstract This article aims to analyze the bioethical aspects and legal and political issues of water fluoridation, creating a discussion based on established studies and new research, in order to contribute to an ethical and impartial perspective on the subject. A bibliographic review study was performed, based on a survey of specialized literature on “fluoridation”, “bioethics” and “fluoride poisoning”. Water fluoridation is an important public health measure for the prevention of dental caries, and its efficacy has been demonstrated in several studies. As it is mandatory under Brazilian law, bioethical dilemmas arise due to the absence of individual choice on whether to consume or not consume fluoridated water. There appears to be no solution to this moral dilemma, as even if the measure were free from any risk, its compulsory application would still violate the principle of autonomy.

title: Physico-chemical technologies for nitrogen removal from wastewaters: a review

description: The paper examines the main physico-chemical processes for nitrogen removal from wastewaters, considering both those that have been long known and still widely applied at the industrial scale, and those that are still at the research level. Special attention is paid to the latest technological developments, as well as to operational problems and fields of application. The processes considered are briefly summarized as follows: ammonia air and steam stripping; ammonia vacuum distillation; ammonia precipitation as struvite; ammonia and nitrate removal by selected ion exchange; breakpoint chlorination; chloramine removal by selected activated carbon; ammonia adsorption on charcoal; chemical reduction of nitrate; advanced oxidation processes to convert ammonia and organic-N into nitrogen gas or nitrate. Special attention is given to advanced oxidation processes, as great research efforts are currently addressed to their implementation. These specifically include ozonation, peroxon oxidation, catalytic wet air oxidation, photo-catalytic oxidation and electrochemical oxidation.

title: Learning to read and its implications on memory and cognition

description: Abstract Can learning to read change the information process and expand the storage capacity of the human brain? The purpose of this article is to review and to discuss models of memory (working memory, short term and long term memory) in their relation to language, as well as the possible cognitive changes prompted by literacy. By reviewing models of memory and executive functions, we aim at identifying questions that have promoted theoretical evolution, as well as the matching and disagreement in the concepts available in the area. Differences in knowledge processing and storage in literates and illiterates are highlighted, taking into account behavioural and brain imaging data. The data suggest that literacy alters the way in which linguistic knowledge is stored and processed by bursting the refinement of the visual and auditory perceptual systems, necessary to the grapheme-phoneme association.

title: Scenes of a Mathematics class: territory and gender relations in Youth and Adult Education

description: Abstract This article proposes the incorporation of two categories of analysis – gender and territory – to the reflection on mathematical practices carried out by students of the Youth and Adult Education (in Portuguese, Educação de Pessoas Jovens e Adultas, EJA). The theoretical framework establishes a dialogue between the fields of Mathematics Education, Geography and Gender Studies to analyze the empirical material produced through the observation of mathematics classes and interviews with recyclable materials collectors, aged between 18 and 69, who participated in an EJA project in an Association. The text exposes the tensions between the desire for uniformity of the mathematical practices of the school territory and the heterogeneity of these practices in the territories of the house and of the work. The abdication of the understanding of the symbolic, the economic and the political marks of these territories, determines the silencing of other mathematical practices in the school context, increasing the inequality of gender relations.

title: Association between HPV infection and prostate cancer in a Mexican population

description: Abstract The aim of this study was to evaluate the association between prostate cancer (PCa) and Human papillomavirus (HPV) infection in the Mexican population. We studied 356 paraffin-embedded tissues from unrelated Mexican men with PCa or benign prostatic hyperplasia (BPH), with the latter serving as control. HPV detection was performed by polymerase chain reaction (PCR) using universal primers, and viral genotypes were detected using sequencing or multiplex PCR. Light microscopy analyses enabled the identification of koilocytes in samples subsequently analyzed for HPV detection by in situ PCR and for p16-INK4A expression by immunohistochemistry. The results showed that high risk- (HR) HPVs were detected in 37/189 (19.6%) PCa specimens compared to 16/167 (9.6%) of BHP specimens (odds ratio 2.3; 95% CI= 1.2 to 4.3; p=0.01). These data suggest HR-HPV may play a role in PCa. HPV 52 and 58 were the most frequent genotypes (33 and 17%, respectively) detected in the population studied. Koilocytes were detected in all in situ PCR-HPV-positive samples, representing a pathognomonic feature of infection, and we observed the overexpression of p16-INK4A in HPV-positive samples compared to HPV-negative samples, indirectly suggesting the presence of HR-HPV E7 oncoprotein. These results suggest that HPV infection plays an important role in prostate cancer development.

title: HEART RATE AND PERCEIVED EXERTION RESPONSES TO PROTOCOL INCREMENTAL SPEED DYNAMOMETRY FOR WHEELCHAIRS

description: ABSTRACT To check the cardiac and perceptual responses an incremental protocol on the wheelchair dynamometer, eight volunteers were intentionally selected and evaluated in an experimental session using a compact dynamometer for wheelchairs. A standard wheelchair was used by all participants. After familiarization period, there was a progressive protocol, increasing rate of 5% per minute. Heart rate (HR) and rating of perceived exertion (RPE, 6-20) were measured at the end of every minute. HR on stage 8 was higher compared to the stages 1 and 2. The RPE differed in the first 5 stages. There was a high correlation between FP and FC (r = 0.93; p = 0.0006), and between HR and RPE (r = 0.98; p &lt;0.0001). It was concluded that the equipment has specificity for evaluation of kinetic and kinematic variables of the movement in wheelchairs at the expense of cardiac variables.
