ABSTRACTUterine leiomyomas are benign soft-tissues tumors that arise from uterine smooth muscle tissue. Etiopathogenesis of leiomyomas is not well understood. We aimed to examine whether antioxidant enzyme activities and lipid hydroperoxides level in patients with leiomyoma are influenced by changes in sex hormones and gonadotropins (estradiol (E2), progesterone, FSH, and LH) during menstrual cycle and in postmenopause. The material consisted of blood and uterine tissue specimens. Hormone concentrations were determined and assays for superoxide dismutase, catalase, glutathione peroxidase and glutathione reductase activities and lipid hydroperoxides concentration were performed. In blood of examined women, a significant difference in catalase, glutathione peroxidase and glutathione reductase activity was recorded among the phases. There was also a positive correlation between the estradiol/progesterone concentration and the catalase activity. Progesterone negatively correlated with lipid hydroperoxides level. In myoma tissue, we recorded a phase-related difference in lipid hydroperoxides level and activities of superoxide dismutase, glutathione peroxidase activities, and glutathione reductase. Negative correlation was observed between FSH and glutathione peroxidase. The results suggest that antioxidant status in patients with uterine leiomyoma is influenced by the changes in sex hormones during the menstrual cycle and in postmenopause, indicating a role of the observed relationship in the leiomyoma etiology.

Objective To estimate the clinical and demographics aspects that may contribute to cognitive impairment and psychiatric symptoms in Parkinson’s disease (PD). Method All patients answered a structured standardized clinical questionnaire. Two movement disorders specialists performed the following scale: Unified Parkinson’s disease rating score (UPDRS), the modified Hoehn and Yahr staging, Schwab and England Scale, SCOPA cognition (SCOPA-COG), SCOPA-Psychiatric complications (SCOPA-PC) and Non-Motor Symptoms Scale (NMSS). We built a generalized linear model to assess predictors for the SCOPA-COG and SCOPA-PC scores. Results Almost 37% of our patients were demented as per SCOPA-COG scores. Level of education and the UPDRS-Subscale III were predictors of cognitive impairment. Higher scores in domain 3 of NMSS and male gender were associated with psychiatric complications as assessed per the SCOPA-PC. Conclusion Level of education and disease severity are predictors of dementia in PD. Psychiatric complications are more commonly observed in men.
O papel da burocracia de nível de rua na implementação e (re)formulação da Política Nacional de Humanização dos serviços de saúde de Porto Alegre (RS)

Resumo Este artigo analisa a implementação da Política Nacional de Humanização nas unidades básicas de saúde de Porto Alegre. Para isso, foi utilizada a abordagem de análise baseada na interação que enfatiza o processo de influência mútua entre o plano da política pública e as características dos espaços locais de implementação. Assim, situa o olhar nos contextos de atuação das burocracias de nível de rua, ressaltando o papel exercido por sua discricionariedade. A pesquisa foi qualitativa com a utilização de dados primários e secundários. Averiguou-se que os implementadores, diante da falta de treinamento nos marcos da política, da percepção de carência de recursos e do baixo grau de apoio, forjaram um entendimento peculiar dos objetivos e das estratégias da política. Eles criaram uma visão do que seria humanizar os serviços, inspirada pela estrutura normativa e ajustada às preferências e necessidades locais.

ABSTRACT Objective The objective of this study was to evaluate the long-term effects of a Brazilian smoking cessation support program and the factors that are associated with its success. Methods A longitudinal study was conducted from 2012 to 2014 with 84 patients enrolled in smoking cessation support groups in a Primary Care Center from a poor community in Rio de Janeiro (Brazil). Support was provided according to Brazilian Tobacco Control Program and consisted of cognitive behavioral therapy in addition to nicotine replacement therapy. Logistic regression and the Cox proportional hazard models were used in the analysis. Results There was an increase of 34%, 48% and 97% in the chances of patients stop smoking for at least six months, 12 months and 24 months, respectively, for each new session that the patient participated. Patients that attended three or more meetings had a 79% lower risk of returning to smoking than those who went to less than three meetings. Conclusions Although not all patients who were enrolled in the program could be contacted for the study, our results indicate that about 40% of patients are able to stay smoke-free for at least three months due to the smoking cessation program, but less than 20% are able to remain smoke-free for two years. Initiatives to improve adherence to cognitive behavioral therapy meetings according to the specificity of the population may increase the effectiveness of the program.

Published: March 2017

RESUMO Os Tabuleiros Costeiros são áreas com relevo aplainado cortadas por vales, que apresentam predominantemente Argissolos Amarelos e Latossolos Amarelos. Contrastando com essa paisagem, existem depressões circulares conhecidas por lagoas, que imprimem nova dinâmica na formação dos solos, em razão da presença intermitente de água ao longo do ano. Os solos dessas áreas ainda são pouco conhecidos, o que implica na possibilidade de uso e manejo inapropriado. Objetivou-se descrever morfologicamente, caracterizar física e quimicamente e classificar os solos existentes em duas dessas áreas de lagoas, visando obter informações para subsidiar um manejo mais adequado. Constatou-se a presença de solos classificados como Organossolo Háplico Sáprico sódico, Gleissolo Háplico Sódico vertissólico (dois perfis), Gleissolo Háplico Sódico típico, Gleissolo Sálico Sódico vertissólico, Planossolo Háplico Eutrófico solódico e Vertissolo Hidromórfico Sódico salino. Esses solos apresentaram cores acinzentadas, típicas do hidromorfismo intermitente observado nas áreas, textura predominantemente mais fina, chegando às classes texturais argilosa e muito argilosa, e estrutura predominantemente maciça, aspectos que prenunciam baixa aeração, o que, juntamente com a alta porcentagem de saturação por sódio, indicam grandes limitações físicas e químicas. Esses aspectos recomendam seu uso como áreas de preservação permanente.

Polímeros Molecularmente Impressos (MIPs) são polímeros sintéticos que apresentam alta seletividade a uma molécula de interesse. O objetivo deste trabalho foi a síntese e caracterização de MIPs para aplicação na extração em fase sólida (SPE), visando a determinação de fenilalanina. Os MIPs foram sintetizados a partir do MAA, fenilalanina, EGDMA, AIBN, em clorofórmio. Também foi sintetizado o polímero não-impresso (NIP), para controle da seletividade dos MIPs. A dessorção da fenilalanina foi realizada em extrator Soxhlet. Os MIPs e NIP foram caracterizados pelas técnicas de análise: FTIR, UV-Vis, MEV, DSC e TG. O MIP apresentou maior capacidade adsortiva à fenilalanina do que o NIP, com uma taxa média de adsorção de 55% comparada a 11% para o NIP. Por MEV o MIP apresentou superfície mais porosa, importante característica para aplicação em SPE. Os estudos realizados mostraram que o MIP sintetizado apresentou grande potencial para aplicação em técnica de SPE.

ABSTRACT CONTEXT AND OBJECTIVE: Post-thoracotomy pain is a severe and intense pain caused by trauma to ribs, muscles and peripheral nerves. The current study aimed to compare subpleural analgesia (SPA) with thoracic epidural analgesia (TEA) in patients undergoing thoracotomy. DESIGN AND SETTING: Randomized study at Ankara Numune Education and Research Hospital, in Turkey. METHODS: Thirty patients presenting American Society of Anesthesiologists physical status I-III were scheduled for elective diagnostic thoracotomy. The patients were randomized to receive either patient-controlled SPA or patient-controlled TEA for post-thoracotomy pain control over a 24-hour period. The two groups received a mixture of 3 µg/ml fentanyl along with 0.05% bupivacaine solution through a patient-controlled analgesia pump. Rescue analgesia was administered intravenously, consisting of 100 mg tramadol in both groups. A visual analogue scale was used to assess pain at rest and during coughing over the course of 24 hours postoperatively. RESULTS: In the SPA group, all the patients required rescue analgesia, and five patients (33%) required rescue analgesia in the TEA group (P < 0.05). Patients who received subpleural analgesia exhibited higher visual analogue scores at rest and on coughing than patients who received thoracic epidural analgesia. None of the patients had any side-effects postoperatively, such as hypotension or respiratory depression. CONCLUSION: Thoracic epidural analgesia is superior to subpleural analgesia for relieving post-thoracotomy pain. We suggest that studies on effective drug dosages for providing subpleural analgesia are necessary.
Can microcystins affect zooplankton structure community in tropical eutrophic reservoirs?

Published: March 2017

Abstract The aim of our study was to assess whether cyanotoxins (microcystins) can affect the composition of the zooplankton community, leading to domination of microzooplankton forms (protozoans and rotifers). Temporal variations in concentrations of microcystins and zooplankton biomass were analyzed in three eutrophic reservoirs in the semi-arid northeast region of Brazil. The concentration of microcystins in water proved to be correlated with the cyanobacterial biovolume, indicating the contributions from colonial forms such as Microcystis in the production of cyanotoxins. At the community level, the total biomass of zooplankton was not correlated with the concentration of microcystin (r2 = 0.00; P > 0.001), but in a population-level analysis, the biomass of rotifers and cladocerans showed a weak positive correlation. Cyclopoid copepods, which are considered to be relatively inefficient in ingesting cyanobacteria, were negatively correlated (r2 = – 0.01; P > 0.01) with the concentration of cyanotoxins. Surprisingly, the biomass of calanoid copepods was positively correlated with the microcystin concentration (r2 = 0.44; P > 0.001). The results indicate that allelopathic control mechanisms (negative effects of microcystin on zooplankton biomass) do not seem to substantially affect the composition of mesozooplankton, which showed a constant and high biomass compared to the microzooplankton (rotifers). These results may be important to better understand the trophic interactions between zooplankton and cyanobacteria and the potential effects of allelopathic compounds on zooplankton.

Published: March 2017

In autumn 2011 in cyprinid farms located in Iasi on the Jijia river, several infections with bacterial strains and macroscopical external cysts on the skin were diagnosedwhich developed as a result of the stress induced by biotic and abiotic factors. On the examination of the cyst contents the presence of numerous spores was observed, mostly of the Dermocystidium spgenusThe samples were taken from the common carp (Cyprinus carpio) and crucian carp (Carassius auratus gibelio)species from the fish farm as well as from the Jijia River. 35 fish were examined, all of them showing cysts, fragmentation of their dorsal fin and congestion of the gills. Histological examination of the skin showed a field of multiple dermal cysts with round light eosinophilic formations (14-16µm) containing a central refractable body similar to that reported for Dermocystidium sp.Gills samples were taken from the affected areas for the SEM examination with the purpose of evaluating not only aspects of normal morphology, but also aspects of some modifications of the affected areas as well as the presence of the etiologically incriminated bacteria Pseudomonas fluorescens. The isolates were identified through phenotypic methods. All the strains that showed mobility and oxidase-positivity were tested using API 20 NE strip. Consequently, they were taxonomically grouped into the species Pseudomonas fluorescens.The scanning electron microscope (SEM) was used for the first time in the characterization of the bacterial lesions produced by Pseudomonasstrains on Cyprinus carpioand Carassius auratus gibeliogills. The diagnosis of septicemia with conditional pathogen species of Pseudomonas fluorescens was correlated with the results of the physico-chemical investigations of water and the data concerning the breeding conditions of the investigated livestock.

SUMMARY Introduction: To assess dietary habits, nutritional status and food frequency in children and adolescents with Down syndrome (DS) and congenital heart disease (CHD). Additionally, we attempted to compare body mass index (BMI) classifications according to the World Health Organization (WHO) curves and curves developed for individuals with DS. Method: Cross-sectional study including individuals with DS and CHD treated at a referral center for cardiology, aged 2 to 18 years. Weight, height, BMI, total energy and food frequency were measured. Nutritional status was assessed using BMI for age and gender, using curves for evaluation of patients with DS and those set by the WHO. Results: 68 subjects with DS and CHD were evaluated. Atrioventricular septal defect (AVSD) was the most common heart disease (52.9%). There were differences in BMI classification between the curves proposed for patients with DS and those proposed by the WHO. There was an association between consumption of vitamin E and polyunsaturated fatty acids. Conclusion: Results showed that individuals with DS are mostly considered normal weight for age, when evaluated using specific curves for DS. Reviews on specific curves for DS would be the recommended practice for health professionals so as to avoid precipitated diagnosis of overweight and/or obesity in this population.

RESUMO

Dentre os diversos fatores que influenciam as perdas de água por evaporação e arraste (PEA) destaca-se o vento. Sendo assim, os objetivos deste trabalho foram: i) determinar os valores de PEA decorrentes de onze avaliações de um sistema de irrigação do tipo pivô central; ii) gerar um modelo para estimativa de PEA a partir de variáveis explicativas; iii) avaliar modelos de predição disponíveis na literatura para estimar PEA a partir de ensaios de campo. Os ensaios foram realizados ao longo de um vão de 48 m, situado entre a quarta e quinta torre de um pivô central de 432,57 m de raio, equipado com sprays de placa oscilante modelo I-Wob. As PEA foram simuladas em função de cinco modelos empíricos propostos na literatura sendo ainda ajustado um modelo específico para a condição estudada. As avaliações de campo em diferentes condições meteorológicas demonstraram que os valores das PEA obtidos com modelos existentes na literatura apresentaram índices de adequabilidade insatisfatórios para as condições estudadas porém o modelo de PEA ajustado apresentou menores erros quando comparado aos modelos existentes, podendo ser utilizado para condições operacionais e climáticas semelhantes às observadas neste estudo.

SUMMARYMajor mineral, major element and minor element compositions are documented for a suite of drill core sediment samples representing a ~350m profile through the Solimões Formation sediments (Western Amazonia). Major element compositions are quantified using a chemical index of alteration (CIA) in order to asses the degree of weathering. Significant variations in CIA values throughout the profile, as well as abrupt changes between overlying, suggest that during the generation and deposition of thes sediments there were rapid changes in the ambient tectonic setting.

O araçá-boi (Eugenia stipitata McVaugh ssp. sororia McVaugh, Myrtaceae) é uma frutífera nativa da Amazônia Ocidental com potencial para a indústria de sucos e flavorizantes. Embora pouco plantada na Amazônia brasileira devido a sua acidez, é frequentemente cultivada na Amazônia peruana. O conhecimento de sua fenologia pode ajudar no planejamento do manejo do plantio e da comercialização dos frutos. A fenologia de dez plantas, crescendo num latossolo amarelo degradado, foi observada durante cinco anos. O araçá-boi geralmente floresceu e frutificou três vezes ao longo do ano e sempre teve pelo menos um pico de floração forte durante a estação seca (julho a setembro) e um pico de frutificação mais acentuado na estação chuvosa (janeiro a março). A floração é um evento complexo e demorado que pode durar de dois a três meses, embora o período entre o aparecimento do botão floral até a antese do flor é curto (~15 dias) e o período entre a antese e a maturação dos frutos dura 50 a 60 dias. As regressões múltiplas usadas para determinar o efeito das variáveis climáticas na floração e frutificação não apresentaram altos coeficientes de determinação, embora os modelos tenham sido significantes, provavelmente porque o araçá-boi floresce várias vezes durante o ano e ainda não se sabe qual o estímulo mais importante para iniciar o processo. O vingamento dos frutos variou de menos de 5% a aproximadamente 15%. O peso médio dos frutos avaliados em janeiro de 1988 foi 135 g, com 77% de polpa. Ao longo do período, estimou-se que as dez plantas produziram cm média 1000 frutos/ano, com uma mediana de 890 frutos/ano. Os insetos visitantes eram principalmente abelhas, especialmente Apis mellifera, Eulaema mocsaryi e Ptilotrigona lurida.

Published: March 2017

ABSTRACT In animal farming, an automatic and precise control of environmental conditions needs information from variables derived from the animals themselves, i.e. they act as biosensors. Rectal temperature (RT) and respiratory rate (RR) are good indicators of thermoregulation in pigs. Since there is a growing concern on animal welfare, the search for alternatives to measure RT has become even more necessary. This research aimed to identify the most adequate body surface areas, on nursery-phase pigs, to take temperature measurements that best represent the correlation of RT and RR. The main experiment was carried out in a climate chamber with five 30-day-old littermate female Landrace x Large White piglets. Temperature conditions inside chamber were varied from 14 °C up to 35.5 °C. The measurements were taken each 30 minutes, over six different skin regions, using a temperature data logger Thermochron iButton® - DS1921G (Tb) and an infrared thermometer (Ti). As shown by the results, the tympanic region is the best one for RT and RR monitoring using an infrared thermometer (TiF). In contrast, when using temperature sensors, the ear (TbE) is preferred to be used for RT predictions and the loin region (TbC) for RR.

Published: March 2017

The aim of this study was to investigate the skills and deficiencies of senior university students enrolled in a mathematics education program with the concepts of symmetry and rotation of geometric figures. The study was conducted with 32 prospective teachers in the Department of Education at a public university located in Western Turkey. This descriptive study was designed with a case study. A structured interview technique was used for data collection. A measurement tool consisting of 12 drawing problems testing symmetry (5 problems) and rotation (7 problems) ability was used in the study. Descriptive statistical methods were used for data analysis. The drawings were analyzed individually, and the students' mistakes and deficiencies were categorized. According to the results of the study, prospective elementary mathematics teachers did not have difficulty in drawing the symmetry of an object or in determining the symmetry axis. However, while they could rotate the figure when a rotation axis was provided, they failed to rotate it in the absence of an axis. In addition, prospective elementary mathematics teachers generally failed to find the center of the given rotated figures. The results of the present study were consistent with results in the literature.

RESUMO Este estudo analisa a preceptoria na perspectiva de médicos em um serviço de emergência e urgência de um hospital de ensino em Goiânia (GO). Teve abordagem qualitativa e participação de 15 médicos no período de janeiro a março de 2013, por meio de entrevista semiestruturada. Na análise dos dados foi utilizada a técnica de análise temática de conteúdo. Constatou-se que os médicos entrevistados consideraram a preceptoria fundamental para o processo ensino-aprendizagem e que ser preceptor significa transmitir conhecimentos e se responsabilizar pela formação profissional. As discussões de casos clínicos e cirúrgicos foram as atividades de preceptoria mais citadas. Os entrevistados relataram que a preceptoria contribuiu para o preceptor continuar aprendendo. Destacaram como facilidades o bom relacionamento com a equipe multiprofissional, o interesse do estudante e a boa formação teórica; como dificuldades, falta de infraestrutura e de tempo, pouca comunicação entre docentes e preceptores, e ausência de capacitação para a preceptoria. Concluiu-se, na perspectiva dos médicos, que a preceptoria contribuiu para a formação dos futuros profissionais e que os preceptores enfrentaram muitas dificuldades no exercício dessa função, razão pela qual sugeriram melhorias na infraestrutura, nas condições de trabalho e em capacitação.

Published: March 2017

Background The involvement of the peripheral nervous system in children with celiac disease is particularly rare. Objective The aim of this study was to assess the need for neurophysiological testing in celiac disease patients without neurological symptoms in order to detect early subclinical neuropathy and its possible correlations with clinical and demographic characteristics. Methods Two hundred and twenty consecutive children with celiac disease were screened for neurological symptoms and signs, and those without symptoms or signs were included. Also, patients with comorbidities associated with peripheral neuropathy or a history of neurological disease were excluded. The remaining 167 asymptomatic patients as well as 100 control cases were tested electro-physiologically for peripheral nervous system diseases. Motor nerve conduction studies, including F-waves, were performed for the median, ulnar, peroneal, and tibial nerves, and sensory nerve conduction studies were performed for the median, ulnar, and sural nerves with H reflex of the soleus muscle unilaterally. All studies were carried out using surface recording electrodes. Normative values established in our laboratory were used. Results Evidence for subclinical neuropathy was not determined with electrophysiological studies in any of the participants. Conclusion In this highly selective celiac disease group without any signs, symptoms as well as the predisposing factors for polyneuropathy, we did not determine any cases with neuropathy. With these results we can conclude that in asymptomatic cases with celiac disease electrophysiological studies are not necessary. However, larger studies with the electrophysiological studies performed at different stages of disease at follow-ups are warranted.

Objective To identify the association between perineal trauma and pain in 473 primiparous women. Method Cross-sectional study in which pain was measured by the numerical pain scale (0 to 10 - 0 being no pain and 10 maximal pain). Results The prevalence and mean intensity of pain were 33.0% and 4.7 points (standard deviation = 2.0) in the numeric scale, respectively. Episiotomy represented the most frequent trauma (46.7%). The occurrence and intensity of the pain were associated with perineal trauma and postpartum time. Having perineal trauma tripled the chance of pain. Each hour elapsed following the birth reduced the chance of pain by 4.8%. Conclusion Primiparous women are subject to a high frequency of perineal trauma, with episiotomy being the most prominent. Perineal pain affects approximately one-third of primiparous women and is associated with the postpartum time and perineal traumas.

The objective of this work was to assess the genetic diversity and population structure of wheat genotypes, to detect significant and stable genetic associations, as well as to evaluate the efficiency of statistical models to identify chromosome regions responsible for the expression of spike-related traits. Eight important spike characteristics were measured during five growing seasons in Serbia. A set of 30 microsatellite markers positioned near important agronomic loci was used to evaluate genetic diversity, resulting in a total of 349 alleles. The marker-trait associations were analyzed using the general linear and mixed linear models. The results obtained for number of allelic variants per locus (11.5), average polymorphic information content value (0.68), and average gene diversity (0.722) showed that the exceptional level of polymorphism in the genotypes is the main requirement for association studies. The population structure estimated by model-based clustering distributed the genotypes into six subpopulations according to log probability of data. Significant and stable associations were detected on chromosomes 1B, 2A, 2B, 2D, and 6D, which explained from 4.7 to 40.7% of total phenotypic variations. The general linear model identified a significantly larger number of marker-trait associations (192) than the mixed linear model (76). The mixed linear model identified nine markers associated to six traits.

Abstract This study aims to analyze the contradictions between anthropological and teleological aspects of evaluation and human rights in educational policies for basic education in Brazil. The study focuses on the contradictions by analyzing policy documents related to the two themes. The results suggest the ways that contradictions in the anthropological and teleological perspectives assumed by these policies obstruct provision of basic education that includes social quality. Basic educational evaluation policies are aimed at regulation, seeking to produce indices that normalize and homogenize the subjects of education, legitimizing identities. On the other hand, human rights educational policies aim to emancipate subjects by considering the diversity that characterizes and organizes them, enabling the creation of resistance and project identities that can operate from a counter-hegemonic perspective.

ABSTRACT Experimental autoimmune uveitis is an organ-specific T-cell mediated autoimmune disease characterized by inflammation and consequent destruction of the neural retina and adjacent tissues. Inflammation in experimental autoimmune uveitis may be induced in rodents by immunization with retinal antigens, such as interphotoreceptor retinoid-binding protein. We present a review of experimental studies that correlate primary immunobiological functions with this chronic disease and the possible use of molecules for the treatment of autoimmune uveitis.

A 23-year-old male with a history of bone marrow transplant for acute myeloid leukemia. He presented a large mass in the right inguinal region 5 years ago. Upon physical examination, right-sided cryptorchidism was observed. The tumor markers alpha-fetoprotein and beta-HCG were within normalcy range and lactate dehydrogenase was raised. Computed tomography of the abdomen and pelvis revealed right testicular mass in contiguity with the inguinal canal to the ipsilateral retroperitoneum, associated with right hydronephrosis. Due to the risk of germ-cell tumor in undescended testicle, the patient underwent radical right orchiectomy. The pathological examination showed recurrence of acute myeloid leukemia in the testis. He was referred to oncology for adjuvant therapy. Our literature review found no similar cases described.

The aim of this study was to examine the relationships among physical fitness of professional Bosnian basketball players (n = 38) and shooting accuracy during one basketball season. A related, secondary aim was to examine relationships between basketball shooting assessments and competitive shooting accuracy during game play. Physical fitness components included: muscular endurance and aerobic endurance, lower and upper-body power, speed, agility, anaerobic capacity and anaerobic power. The specific basketball shooting accuracy was assessed by stationary and dynamic shooting assessments. Competitive shooting accuracy was represented by data collected during one basketball season for each player (free throw, field goal, and three-point %). Results of the regression analyses showed that there were significant positive relationships among shooting assessments and competitive shooting accuracy during game play. The relationship was stronger when the dynamic shooting tests were applied compared to the stationary tests. However, few or weak relationships existed among physical fitness components and competitive shooting accuracy. Only the power tests showed to be good predictors for shooting over longer distances. The findings support the inclusion of the dynamic basketball shooting accuracy tests in regular basketball assessment procedures as a valuable testing instrument.

Abstract Aim Mining activities generate countless environmental impacts, including heavy-metal contamination, sorting and increased turbidity. In aquatic ecosystems these impacts can drastically affect the initial links of the food chain, such as zooplankton. Methods To evaluate how the different mining activities can influence the structure and functional diversity of zooplankton, we investigated the geochemical characteristics of the water and sediment in two small impoundments impacted by different mining activities (kaolin and iron extraction). We also explored zooplankton composition, species diversity and functional diversity (feeding guilds taxa). Results As expected, the water and the sediment of both of the reservoirs showed high concentrations of trace elements, particularly Al, Ba, Fe, Mg, Mn, Sr and Zn. Zooplankton biomass and diversity were markedly reduced (< 12 μg.DW.L-1 and H’ < 1.5, respectively), and negatively correlated with turbidity and total suspended solids. Small microphages dominated the trophic composition of zooplankton, and an alternation of trophic guilds was not observed, since the dynamics of raptorial organisms was essentially linked to the temporal fluctuation of a single species of rotifer (Polyarthra cf. dolichoptera). Conclusions In addition to changes in the aquatic habitat and zooplankton composition, the functional niches were also affected by the mining impacts. The use of the functional diversity analysis can emerge as a valuable approach to understand how zooplankton communities respond to drastic environmental changes.
Cement dispersion performance of superplasticisers in the presence of clay and interaction between superplasticisers and clay

Published: March 2017

A study of superplasticisers (SPs), including polyethylene oxide-free type polycarboxylate superplasticisers (PCEs), a conventional PCE and a polycondensate, was carried out to research their cement dispersion behaviour and interactional behaviour with clay. It was found that the cement dispersion performance of SPs in the presence of clay is dependent on both the cement dispersing capability and clay sensitivity. The sensitivity of superplasticisers to the presence of clay was investigated systematically through a study of water and SP adsorption (surface and interlayer) on the clay. It was found that clay sensitivity is dependent on the clay adsorption of both water and the SP. The behaviours of cations (surface and interlayer) of clay interacting with different SPs were also investigated and the interactional mechanism between SPs and clay was clarified. This work will aid further understanding of the effects of clay in concrete and help in the design of SPs with enhanced clay tolerance.
Municipal incinerated bottom ash use as a cement component in concrete

Published: March 2017

The characteristics of municipal incinerated bottom ash (MIBA) and its potential use as a cementitious component in concrete applications are examined through an analysis and evaluation of global experimental data. As raw feed in cement clinker production, MIBA can be incorporated at minor contents without compromising performance. To avoid damaging hydrogen gas expansive reactions arising due to the metallic aluminium in the ash, treatment of MIBA is required for use as cement components in cement, mortar and concrete. As such, thermal and chemical treatments, as well as tailored slow and wet grinding treatments, have been effective in improving performance. The hydrogen gas expansion associated with MIBA can beneficially contribute towards the lightweight properties required for aerated concrete, with the ash serving as an alternative to aerating agents and also contributing to strength development. Initial work on controlled low-strength materials has highlighted MIBA as a potential cement replacement material that can meet the low-strength requirements.
Between History and Passion: The Legitimacy of Social Clubs in the Province of Buenos Aires (2001–2007)
Authors: Casagrande Agustín Elías
Published: March 2017

In the last few decades the concept of self-regulation accompanied the process of dismantling the welfare state. In this context, in central countries—Europe and North America—the importance given to private regulations versus public action increased, thus requiring new mechanisms of legitimacy. To this end, appeals to the principles of economy and technical efficiency to legitimate private regulations have been made by several researchers. However, these principles acquired a negative view in Argentina because they were used to use to legitimate processes that led to various crises, especially taking into consideration the neo-liberal experience of the 1990s. Against this historical background, this paper seeks to show a particular case of legitimizing the self-regulation of non-state organizations (social clubs) by using classic topoi, which had been historically used to legitimize state action. In order to do so, this text focuses on the analysis of “Luna de Avellaneda” Act of 2007, by which the government of Buenos Aires sought to legitimize the self-regulation of clubs appealing to the classical values of democracy, participation, and solidarity. For this, the historical experience of the Argentinean political community will be observed from the perspective of the history of these clubs, thus recovering the social function they played in the diverse political and economic crises.
