The EU-TecNet monitoring network uses customized three-dimensional extensometers to record transient deformations across individual faults. This paper presents the first results from two newly established monitoring points in the Balkan Mountains in Bulgaria. The data from Saeva Dupka, recorded across an EEN-WWS striking fault, show sinistral strike-slip along the fault and subsidence of the southern block. Much of the subsidence occurred around the time of the distal MW = 5.6 Pernik Earthquake. An important transient deformation event, which began in autumn 2012, was reflected by significant compression and following extension, across the monitored fault. The data from Bacho Kiro, recorded across a NE–SW striking fault, show sinistral strike-slip along the fault and subsidence of the north-western block. The same important deformation event was reflected by changes in the strike-slip, dip-slip, and horizontal opening/closing trends. These results have been compared to data from other monitoring points in the Western Carpathians, External Dinarides, and Tian Shan. Many of the sites show evidence of simultaneous displacement anomalies and this observation is interpreted as a reflection of the plate-wide propagation of a tectonic pressure pulse towards the end of 2012.
Feature Selection Using Particle Swarm Optimization in Text Categorization
Authors: Aghdam Mehdi Hosseinzadeh , Heidari Setareh
Published: October 2015

Feature selection is the main step in classification systems, a procedure that selects a subset from original features. Feature selection is one of major challenges in text categorization. The high dimensionality of feature space increases the complexity of text categorization process, because it plays a key role in this process. This paper presents a novel feature selection method based on particle swarm optimization to improve the performance of text categorization. Particle swarm optimization inspired by social behavior of fish schooling or bird flocking. The complexity of the proposed method is very low due to application of a simple classifier. The performance of the proposed method is compared with performance of other methods on the Reuters-21578 data set. Experimental results display the superiority of the proposed method.

Authors: Wang Guocheng , Zhang Shiguo
Published: October 2015

One of the most important advantage of ABM (Agent-Based Modeling) used in social and economic calculation simulation is that the critical behavioral characteristics of the micro agents can be deeply depicted by the approach. Why, what and how real behavior(s) should be incorporated into ABM and is it appropriate and effective to use ABM with HSCA collaboration and micro-macro link features for complex economy/finance analysis? Through deepening behavioral analysis and using computational experimental methods incorporating HS (Human Subject) into CA (Computational Agent), which is extended ABM, based on the theory of behavioral finance and complexity science as well, we constructed a micro-macro integrated model with the key behavioral characteristics of investors as an experimental platform to cognize the conduction mechanism of complex capital market and typical phenomena in this paper, and illustrated briefly applied cases including the internal relations between impulsive behavior and the fluctuation of stock’s, the asymmetric cognitive bias and volatility cluster, deflective peak and fat-tail of China stock market.

Authors: Rebba Bhargavi , Ramanaiah N.
Published: October 2015

The results of an experimental investigation of the mechanical properties of boron carbide (B4C) and molybdenum disulphide (MoS2) reinforced aluminium alloy (AA2024) hybrid composite samples, processed by stir casting process are reported in this paper. Based on the previous studies, it was concluded that for 4% of weight of the B4C powders reinforced in AA2024 metal matrix have better mechanical properties like tensile strength and hardness than the base alloy. Also the 4% of MoS2 reinforced in AA2024 metal matrix exhibited good mechanical properties than the matrix metal. Hence an attempt has been made to further improve the properties of the composite using both B4C and MoS2 as reinforcement particles in the AA2024 matrix. in the present study hybrid composite specimen were developed varying the weight% of B4C and MoS2, viz., 1%+3%, 2%+2%, 3%+1% B4C and MoS2 respectively in the AA2024 matrix. The prepared samples were subjected to a series of mechanical tests like tensile and hardness tests. Further, SEM & XRD analyses were performed on the prepared samples to study the microstructure and to ensure the proper dispersion of the reinforced particles in the metal matrix.
Comparative Study for Buckling Resistance of Steel Sheets Provided with Stiffeners Used in Bridge Structures
Authors: Daraban Marian
Published: October 2015

The subject discussed in this paper is based on an experimental bridge model which was built to study the pre-critical and post-critical buckling behaviour of steel webs of box girders provided with longitudinal and transversal stiffeners. The article presents a comparison between the experimental results and the numerical ones for buckling resistance of stiffened steel webs. For this purpose two types of analysis will be carried out: an analysis to establish the values and eigenvectors of buckling, after which the critical factor for the first mode of buckling will be obtained, and then a geometrical and physical nonlinear analysis will be performed.
Global Ductility of Dual Steel Frames with Replaceable Dissipative Shear Walls
Authors: Neagu Calin , Dinu Florea , Dubina Dan
Published: October 2015

The paper presents the results of a numerical program that was used to investigate the seismic performance of dual steel frames with dissipative shear walls. Nonlinear static and dynamic analyses were employed in order to evaluate the global ductility and the q factor for a twelve story building. The influence of the q factor on the estimated level of damage and post-earthquake intervention strategy was investigated. The dynamic analyses were conducted using two groups of accelerograms, selected to match the response spectra of two types of grounds. The numerical models were validated against experimental tests. The results show that q factor values adopted in design influence the level of damage. If re-centering capacity is properly controlled by design, the replacement of damaged walls can minimize the time and cost of intervention, thus supporting disaster resilience of buildings
Case Study on Vulnerability Increase for a Reinforced Concrete Frame Structure
Authors: Olteanu Ioana , Canarache Radu Marian , Budescu Mihai
Published: October 2015

Seismic vulnerability for a structure represents the susceptibility to be affected by an event with a given intensity. The vulnerability of a structure can be influenced by the design methods or by different problems that may appear during the execution process.

This paper shows a case study for the vulnerability increase of a reinforced concrete frame structure in 2 different situations:

a) modification produced due to code changes, meaning P100-2006 respectively P100-2013;

b) modifications produced the structure taking into account the errors which have occurred during the execution process;

For both cases, capacity curves were plotted considering the nonlinear analysis, also called pushover. The numerical simulation was performed in SAP2000 software. These curves were compared with the response spectrum corresponding to the site conditions in order to obtain the performance point. For accurate results, fragility curves were plotted for both considered situations, according to previous research of the authors.

The paper emphasizes the importance of each stage during the execution of a structure. More over the differences in the vulnerability index show the importance on the overall behavior of the structure. Solution to increase strength and safety for the structure are also given at the end of the paper
Reduction of the Mean Hedging Transaction Costs / Redukcija povprečnih transakcijskih stroškov hedging tehnike
Authors: Mastinšek Miklavž
Published: October 2015

Transaction costs of derivative hedging appear in financial markets. This paper considers the problem of delta hedging and the reduction of expected proportional transaction costs. In the literature the expected approximate proportional transaction costs are customarily estimated by the gamma term, usually the largest term of the associated series expansion. However, when options are to expire in a month or few weeks, other terms may become even larger so that more precise estimates are needed. In this paper, different higher-order estimates of proportional transaction costs are analyzed. The problem of the reduction of expected transaction costs is considered. As a result, a suitably adjusted delta is given, for which the expected approximate proportional transaction costs can be reduced. The order of the mean and the variance of the hedging error can be preserved. Several examples are provided.

Published: October 2015

This study investigates the effectiveness of virtual reality (VR) technology in distracting attention from pain. We tested how body engagement related to navigating the virtual environment (VE) influences the intensity of pain. Two different interfaces were used to play the same VE, and a cold pressor test was used for pain stimulation. A mixed design was used for the experiment. Sixty-six undergraduate students participated. One group navigated the game using a rotation sensor, head tracker and foot pedals (Body Movement Interface). Another group navigated only using their hands (Hand Movement Interface). Objective and subjective measures of pain were collected - the amount of time participants kept their hand in a container with cold water, and the participant’s assessment of the pain intensity on a visual analog scale (VAS). Participants also filled in questionnaires designed to measure feelings of presence in VE and emotional attitudes towards the game. We found no significant difference between the two used interfaces in their analgesic efficacy. In both groups during VR distraction, participants showed significantly higher levels of pain endurance than without VR distraction.
Coping with anxiety in patients undergoing hip replacement
Authors: Stecz Patryk , Kocur Józef
Published: October 2015

Our research aim was to answer whether temperament traits could predict the anxiety experienced by osteoarthritis patients before and after arthroplasty; we analyzed if coping styles moderated the relationship between temperament and perioperative anxiety, and examined the fluctuation of perceived stress and anxiety.

In the longitudinal study (N=61, mean age 70.9) we measured temperament traits (EAS-A), coping styles (Brief-COPE) and changes of perceived anxiety (STAI) and stress (PSS-10), before and after arthroplasty.

Anxiety and stress decreased significantly after the surgery. Temperament correlated with the anxiety state. Positive correlates were anger, negative affectivity, and fear while negative correlates included sociability and vigor. Regression analyses indicated the predictors of preoperative anxiety which included vigor and negative affectivity. The regression model for the variation of postsurgical anxiety indicated that negative affectivity explained the variance of this variable (R2=0.57). Moderation analyses confirmed that the temperament and anxiety relationship depended on: active coping, acceptance and planning.

Vulnerable patients with temperamental emotionality and ineffective coping report heightened perioperative anxiety, while effective coping moderates the temperament and anxiety relationship.
Psychometric properties of Self-Perception Profile for Children in a Polish sample
Authors: Gacek Michał , Pilecka Władysława , Fusińska-Korpik Agnieszka
Published: October 2015

The Self-Perception Profile for Children (SPPC) is a measure which allows one to assess children’s self-concept. Our article presents this instrument’s psychometric properties within a Polish sample. In our study we tested 432 elementary school students and 14 form teachers. As validity indicators we used the Teacher’s Rating Scale of Child’s Actual Behavior (TRS) and the average school grade for the previous semester. The Polish version of SPPC yielded good psychometric properties. The instrument’s factorial structure paralleled the structure of the original version. Reliability was high both in terms of internal consistency and test-retest results. Scale validity was confirmed in the correlational analysis. Boys scored higher than girls in the Physical Appearance and Global Self-Worth subscales but lower in the Behavioral Conduct subscale. Younger children scored higher than older children in the Scholastic Competence, Physical Appearance, and Global Self-Worth subscales. Judgments on children’s physical appearance were the best predictor of their global self-worth.

Published: October 2015

Virtual Reality (VR) technology can be applied during pain treatment, acting as an effective distractor from pain stimuli. In our paper we investigate how memory influences experienced intensity of thermal pain stimuli. An experiment (within subject design) was conducted on 35 students from various Wroclaw universities. A cold pressor test was used for pain stimulation. Participants were immersed in customized virtual environments, created for this particular study. The environments differed at the level of memory engagement while playing a game. Pain measures were determined by the length of time participants kept their hands in cold water (pain tolerance), and their pain rating intensity was measured on the VAS scale (pain intensity). Participants were asked to put their hand in a container with cold water and keep it there until the pain became difficult to bear.

In both VR conditions participants kept their hands in the cold water significantly longer than in a non-VR (control) condition. Results of pain intensity measures were in conclusive. We did not find any significant differences in effectiveness in the virtual environments that were used.
Which literary theory tools can a psychologist use for interpreting language communication?
Authors: Kuncewicz Dorota , Sokołowska Ewa , Sobkowicz Jolanta
Published: October 2015

The theory of literature provides tools for interpreting language communication. A psychologist, when interpreting a communication - which is often a latent one - has no other alternative but to employ these tools (with the exception of non-verbal communication). Often, however, this stage of work is defined as “intuitive”, which significantly limits the repeatability of the procedure and thus gives rise to reservations as to its scientific value. Review of certain literary theory devices, along with their possible applications, allows for naming these tools, selecting, and ordering the consecutive stages of communication analysis. In our opinion, such reviewing opens up the possibility for filling this gap in qualitative research analysis with specific tools and specific ways of using these tools in place of intuitiveness.
Processing Fluency and Decision-Making: The Role of Language Structure
Authors: Deckert Mikołaj
Published: October 2015

This paper models conventionalisation of language structure as constitutive of processing fluency. I postulate that the difference in conventionalisation of linguistic forms used for communication significantly influences our reasoning about linguistically-expressed problems. Two studies are reported that tested this hypothesis with the use of variably conventionalised - fluent and disfluent - formulations of problem-solving tasks. Th e findings indicate that even in tasks requiring analytic reasoning, the degree to which the linguistic forms employed to communicate are conventionalised is correlated with the subjects’ performance success rate. On a more general level, this paper seeks to empirically address the nature of links between linguistic form and meaning construction.
It is the Spirit who gives life (John 6:63): Experience and the Formulation of Theology
Authors: Zaprometova Olga
Published: October 2015

This paper was presented at the international conference “Theology of the Holy Spirit: Personal Experience and Charismatic Movements in Contemporary Churches” held in Sibiu (2014). Although the role of the charismatic experience in the history of Christianity is a well-known fact it is still of particular interest for today due to the growth of Pentecostalism and charismatic movements worldwide. By turning to Hildegard of Bingen and to Martin Luther for a better understanding of the “faith of the heart”, this study aims to emphasize faith not just as a matter of understanding God but rather as experiencing the real presence of the Holy One. A particular focus is on clarifying terms and seeking the understanding of one another’s positions on the issue of the Holy Spirit.
The Problem of the Place of the Person of the Holy Spirit in Orthodox Ecclesiology of the 20th Century (on the example of Eucharistic ecclesiology of Nicholas Afanasiev)
Authors: Bobkova Kseniya
Published: October 2015

The question of the place of the Holy Spirit in the Orthodox Ecclesiology is not a new one, but it still remains open. In this article special attention is devoted to the Eucharistic Ecclesiology of Nicholas Afanasiev, in which he has tried to give to the Person of the Holy Spirit an essential place, and to the ecclesiological ideas of George Florovsky, who in his theological constructions has been extreme Christocentric and has avoided to give a special place to the oikonomia of the Spirit. A particular remark is made also about the possibility of using the neo-patristic synthesis in the discussion (with special reference the texts of St. Basil the Great, St. Athanasius of Alexandria and Didymus the Blind).
Towards a Pneumatological-Ecclesiology: Outside the “Two Lungs of the Church”
Authors: T.N. Timothy Lim
Published: October 2015

This paper critiques the framing of the pneumatological underpinning of ecclesiology as an Orthodox-Catholic conversation. The context for the Joint Commission for Orthodox-Catholic dialogue warrants the use of the metaphor “two lungs of the church” by official church leaders, ecclesiologists and theologians to speak of the Spirit’s work in and between both communions. However, I want to call attention to the pneumatological and ecclesiological problems in the use of the image “two lungs of the church.” If the Holy Spirit breathes upon and through the Body of Christ, reading the Spirit’s operation in the church (pneumatological-ecclesiology) cannot ignore, and much less dismiss or absorb (either explicitly or implicitly), the charismas outside of the Roman Catholic Church and Orthodoxy. Protestant denominations, such as Baptists, Brethren, Evangelicals, Presbyterians, Pentecostals and Charismatics are also contexts for studying the Spirit’s work in the churches. The paper concludes by proffering a mapping of recent pneumatological contributions of other Christian denominations and churches to invite theologians to assist in reframing or reconceptualizing a more appropriate anatomic metaphor for the Spirit’s work in and among the churches together.

Corral
Authors: Rusted Brian
Published: October 2015

Released in 1954 by the National Film Board of Canada, Corral was Colin Low's debut as a director. Low later became identified with the landmark Challenge for Change films using documentary film as a catalyst for community organizing. Although local folk knowledge is frequent in discussions of documentaries made by the French branch of the NFB, it has been more common to treat the English projects of NFB as romantic evocations of place. Corral is often the exemplary case. This article uses paradigms of performance and practice to consider the embodied knowledge and traditional skills depicted in Corral. The place that Corral performs is characterized by the popular diffusion of traditional vaquero skills from California mixed with embodied practices of ranching in southwestern Alberta.
Don't Take Your Body to the West
Authors: Kumar Hari Stephen
Published: October 2015

What do the narratives of the West(ern) say about which bodies are celebrated and which bodies are warned away in the West(ern)? And how do such narratives echo globally while reinforcing American patterns of racist violence against nonwhite bodies? In this autoethnographic cultural analysis, I interweave songs and visuals with personal narratives of growing up in the Middle East and with continued incidents of racial violence in America. I seek to show how West(ern) ideologies celebrate a narrow kind of white masculine vigilantism that affords most white people the luxury of seeing themselves nostalgically and sympathetically portrayed as individuals in West(ern) narratives while condemning members of nonwhite races as collectively criminal.
Coordination of Recombination with Meiotic Progression in the Caenorhabditis elegans Germline by KIN-18, a TAO Kinase That Regulates the Timing of MPK-1 Signaling
Authors: Yin Yizhi , Donlevy Sean , Smolikove Sarit
Published: October 2015

Meiosis is a tightly regulated process requiring coordination of diverse events. A conserved ERK/MAPK-signaling cascade plays an essential role in the regulation of meiotic progression. The Thousand And One kinase (TAO) kinase is a MAPK kinase kinase, the meiotic role of which is unknown. We have analyzed the meiotic functions of KIN-18, the homolog of mammalian TAO kinases, in Caenorhabditis elegans. We found that KIN-18 is essential for normal meiotic progression; mutants exhibit accelerated meiotic recombination as detected both by analysis of recombination intermediates and by crossover outcome. In addition, ectopic germ-cell differentiation and enhanced levels of apoptosis were observed in kin-18 mutants. These defects correlate with ectopic activation of MPK-1 that includes premature, missing, and reoccurring MPK-1 activation. Late progression defects in kin-18 mutants are suppressed by inhibiting an upstream activator of MPK-1 signaling, KSR-2. However, the acceleration of recombination events observed in kin-18 mutants is largely MPK-1-independent. Our data suggest that KIN-18 coordinates meiotic progression by modulating the timing of MPK-1 activation and the progression of recombination events. The regulation of the timing of MPK-1 activation ensures the proper timing of apoptosis and is required for the formation of functional oocytes. Meiosis is a conserved process; thus, revealing that KIN-18 is a novel regulator of meiotic progression in C. elegans would help to elucidate TAO kinase’s role in germline development in higher eukaryotes.
Cell Differentiation and Spatial Organization in Yeast Colonies: Role of Cell-Wall Integrity Pathway
Authors: Piccirillo Sarah , Morales Rita , White Melissa G , Smith Keston , Kapros Tamas , Honigberg Saul M
Published: October 2015

Many microbial communities contain organized patterns of cell types, yet relatively little is known about the mechanism or function of this organization. In colonies of the budding yeast Saccharomyces cerevisiae, sporulation occurs in a highly organized pattern, with a top layer of sporulating cells sharply separated from an underlying layer of nonsporulating cells. A mutant screen identified the Mpk1 and Bck1 kinases of the cell-wall integrity (CWI) pathway as specifically required for sporulation in colonies. The CWI pathway was induced as colonies matured, and a target of this pathway, the Rlm1 transcription factor, was activated specifically in the nonsporulating cell layer, here termed feeder cells. Rlm1 stimulates permeabilization of feeder cells and promotes sporulation in an overlying cell layer through a cell-nonautonomous mechanism. The relative fraction of the colony apportioned to feeder cells depends on nutrient environment, potentially buffering sexual reproduction against suboptimal environments.

To contribute to the knowledge of beetles (Coleoptera) of the mountainous region of Morocco, Talassemtane National Park (Western Rif, Chefchaouen district, Morocco) was surveyed. This is an exceptional protected area of the Mediterranean Intercontinental Biosphere Reserve (RIBM). The inventory was made using different traps combined with active searching periodically during 2013 and 2014. Among numerous species belonging to various families, the darkling beetles (Tenebrionidae) represent one of the major groups, in terms of diversity and heritage value. Thirty five species were identified, two species are new records to Morocco, and two other species, which were hitherto only known by the type specimens, have been rediscovered.
Anticoagulation for Atrial Fibrillation in End-stage Kidney Disease
Authors: Lee Gavin , Johnson David W
Published: October 2015

Atrial fibrillation (AF) is the most common arrhythmia in the general population and it has been found to have a higher prevalence in end-stage kidney disease (ESKD). It is associated with a higher risk of stroke and mortality compared to those without AF.  Patients with ESKD have generally been excluded from randomized controlled trials (RCTs) evaluating the efficacy of anticoagulation in reduction of stroke risk. Current observational evidence for anticoagulation for AF in the ESKD population has yielded conflicting results, but in aggregate favours a lack of benefit in stroke risk reduction with an increase in bleeding risk. There are also reports that warfarin use in ESKD patients on dialysis is associated with greater International Normalised Ratio (INR) variability and increased risk of vascular calcification and calciphylaxis (uraemic calcific arteriolopathy). RCTs are required to assess the net clinical benefit of anticoagulation in this group.
Dialogues between social and natural sciences: contribution to the debate on socio-environmental conflicts
Authors: Milanez Bruno
Published: October 2015

ABSTRACT In this article, I argue that attempting to solve real problems is a possible approach to bring social and natural sciences together, and suggest that - as Environmental Impact Assessment necessarily brings together social and environmental issues - this debate is a strong candidate for such a task. The argument is based on a general discussion about the possibilities and limitations of Environmental Impact Assessments, the social-environmental impacts of mining activities and three case studies. The analysis of the cases indicates possibilities and limitations of the dialogue between scientists from various areas - and of the collaboration with social movements and affected communities - in avoiding negative impacts of mining projects and, eventually, increasing their sustainability.

Published: October 2015

AbstractIntroduction Physical exercise is indicated to reduce the incidence of musculoskeletal symptoms in teachers.Objective To evaluate the effects of muscular endurance training on muscle strength and musculoskeletal symptoms related to the lower limbs of public elementary school teachers.Materials and methods Thirty-one female teachers were divided into two groups: control (CG, n = 15) and muscular endurance training (TG, n = 16). The training consisted of two sets of 15 repetitions of exercises for quadriceps and hamstring muscle groups, twice a week, for 7 weeks, which were conducted with 50% of 10 repetition maximum(10RM) (first to fourth week) and 60% of 10 RM (fifth to seventh week). Musculoskeletal symptoms (Nordic Musculoskeletal Questionnaire), isometric peak torque (Load cell) and muscle strength (10RM) were assessed before and after intervention. ANOVA for repeated measures and Tukey post hoc were used to analyse strength and peak torque of quadriceps and hamstrings and Chi-square goodness-of-fit test were used to analyse the frequency of occurrence of osteomuscular symptoms.Results The highest incidence of symptoms was found in the lumbar region in both groups. Training caused increased muscle strength of the quadriceps and hamstrings, but there were no significant differences in either the peak torque in the quadriceps and hamstrings or in the reduction of musculoskeletal symptoms.Conclusion The exercise program performed in this study increased the dynamic strength in the TG in relation to the CG, but did not alter the incidence of symptoms in the lumbar region and lower limbs in neither of the groups. Thus, results suggest that the duration of intervention may not have been enough to increase peak torque and decrease musculoskeletal symptoms.

Published: October 2015

AbstractIntroduction The epidemiological profile is considered a sensitive indicator of living conditions and the disease process. The musculoskeletal disorders are the most common causes of pain and can lead to disability or restriction of daily activities. These disorders take the name of RCT/OWRD when they are associated with work activities and may be associated with risk conditions at work.Objectives To describe the epidemiological profile of supermarket workers with musculoskeletal disorders under treatment at a physiotherapy clinic in the city of Porto Alegre, Brazil.Methods This was a cross-sectional, observational study which used retrospective data collected from 360 records of patients treated from January 2010 to December 2011 in a physiotherapy clinic that provides health services for a supermarket chain.Results There was a predominance of females (73.9%), aged 30–39 years (35.1%); 63.0% reported being single and 73.4% lived in Porto Alegre. The most commonly reported occupation was cashier (31.2%). The main reasons for referral to physiotherapy treatment were low back pain (21.4%), neck pain (19.7%), pain (16.1%), subacromial bursitis (13.9%) and back pain (12.2%). Among the signs and symptoms 95.8% of the sample reported pain in chronic phase.Conclusion The prevalence of musculoskeletal pain was high in this group. The presence of pain can disable the worker for daily activities and physiotherapy becomes the therapeutic procedure of choice for their rehabilitation.

Resumo O trabalho se dedica ao estudo das governanças das transações adotadas pelas distribuidoras de combustíveis no Estado de São Paulo com os postos revendedores varejistas. A partir da desregulamentação do mercado, formas plurais foram permitidas e têm sido recorrentes no mercado. Neste artigo, argumenta-se que as formas plurais encontradas são transitórias, mas que isso não se dá em razão de aumento da eficiência e redução de custos de transação, mas sim pela forma plural ter se tornado um passo estratégico fundamental para alcançar parceiros comerciais e promover maior crescimento da firma. Ademais, argumenta-se que o ambiente institucional apresentou influência significativa na coordenação das formas plurais, interferindo diretamente na estabilidade destas.

Com respeito ao peso, as 16 espécies podem ser divididas em quatro grupos:55 até 110g: Tuit huetii, Pyrrhura picta, Brotogeris chrysopterus, Pyrrhura rhodogaster, Aratinga weddellii.140 até 300g: Aratinga leucophthalmus, Pionopsitta barrabandi, Pionus menstruus, Deroptyus accipitrinus.360 até 600g: Ara severa, Ara manilata, Amazona ochrocephala, Amazona farinosa.950 até 1350g: Ara ararauna, Ara macao, Ara chloroptera.As estratégias alimentares variam dentro de cada grupo de peso: Ara manilata é especialista puro, Tuit huetti, Brotogeris chrysopterus, Pionopsitta barrabandi, Ara severa e Ara ararauna são especialistas parciais. Os especialistas parciais têm bicos relativamente compridos e estreitos. Com respeito às proporções do bico, Brotogerischrysopterus é mais especializado do que Tuit huetii no mesmo grupo de peso.As espécies muito próximas morfologicamente, como Ara chloroptera e Ara macao ou Pyrruhura rhodogaster e Pyrrhura picta, podem ser reconhecidas principalmente pelo modo com que exploram o habitat. Ara chloroptera se encontra nas estratos superiores da floresta, junto às copas de árvores muito altas, com maior freqüência do que Ara macao. Pyrrhura rhodogaster visita mais freqüentemente matas densas e vegetação secundária do que Pyrrhura picta. Diferenças sazonais de abundância e épocas diferentes de reprodução separam as duas espécies de Amazona. Amazona ochrocephala é mais comum e inclusive cria os seus filhotes na época seca, enquanto que Amazona farinosa reproduz e se torna mais comum na época chuvosa.
Vocalizations of primary forest frog species in the Central Amazon.

Published: October 2015

The calls of 18 species of Amazonian forest frogs were recorded in 3 localities: the Tapajos National Park near Itaituba, the Reserva Ducke near Manaus, and the INPA-WWF reserves near Manaus. Structural and time parameters and sonographs of these calls including previously undescribed vocalization by 10 species are presented. Unlike open habitat species, several forest frong species characteriscally demonstrated one on more of the following temporal parameters: very low call rates, sporadic intervals, infrequent nights of calling and synchronized chorusing. It is hypothesized that predation has influenced the evolution of vocal behaviour in Amazonian forest frogs.

RESUMOA espécie Dicksonia sellowiana, conhecida popularmente como xaxim, é uma samambaia natural do continente americano e encontrada no Brasil na Mata Atlântica. Em 2001 foi inserida na lista do IBAMA como espécie ameaçada de extinção em decorrência da exploração para a confecção de vasos para a jardinagem. O presente trabalho descreve o potencial antioxidante lipídico (TBARS e Sistema β-caroteno/ácido linoleico) do extrato bruto e frações obtidos através de aparato de Soxhlet de frondes de Dicksonia sellowiana, além da atividade citotóxica e hemolítica in vitro. Pelo método TBARS, todas as amostras testadas apresentaram atividade, destacando a fração acetato de etila e extrato bruto cuja atividade foi comparável ao padrão ácido ascórbico. No sistema β-caroteno/ácido linoleico, a fração acetato de etila e extrato bruto apresentaram inibição da oxidação do ácido linoleico, destaque para a fração acetato de etila que não se diferenciou estatisticamente do padrão BHT. Na avaliação da toxicidade preliminar, não fora observado atividade citotóxica e hemolítica do extrato bruto e frações nos modelos testados. Os resultados demonstram o potencial antioxidante da espécie vegetal nos modelos de inibição da oxidação lipídica sem apresentar toxicidade.
Retórica e estudos do discurso
Authors: Teixeira Lucia
Published: October 2015

RESUMOO objetivo deste artigo é discutir as articulações retórica/discurso, tendo como centro das reflexões o livro Figuras de retórica do semioticista José Luiz Fiorin. A obra examina a contribuição da retórica clássica aos estudos do discurso e resgata, para ressignificá-la, a noção de ornamento, que relegou a retórica a um simples estudo de figuras. Apresenta estas últimas como operações enunciativas que intensificam o sentido de algum elemento do discurso, o que acaba por lhes restituir sua dimensão argumentativa. O artigo incorpora, à sua própria argumentação, figuras de linguagem e recursos retóricos explicados pelo autor no livro.

ABSTRACTWhite clover is tolerant to many herbicides, making difficult a chemical control of this species during soybean crop establishments. The objective of this research was to select herbicides applied postemergence to control white clover in soybean and know the effects of this control on soybean yield. Seven herbicides were assessed, applied postemergence, with or without sequential application of glyphosate, and two control treatments (no control and total control of white clover). Glyphosate (with two sequential applications), fomesafen (with a sequential application of glyphosate), chlorimuron-ethyl and lactofen have shown a satisfactory control of white clover (above 80%). The lower control efficiency has resulted in lower production of soybeans.

Background: Inguinal hernia repair is the most common procedure in general surgery and 80,000 operations are performed annually in Great Britain, 100,000 in France and 700,000 in the US. Given its high frequency has a major impact, both in the medical and economic aspects. Aim: Analyze the immediate postoperative complications comparing mesh versus non mesh hernioplasty. Method: Randomized control trial, with the enrollment of 263 patients underwent surgery for inguinal hernia randomized by randomization table. Treatment (mesh, Lichtenstein or without mesh, Bassini technique) was assigned using sequentially numbered opaque envelopes having fulfilled the inclusion criteria. The variables analyzed were: postoperative pain, seroma, hematoma, infection, return to normal activities and recurrence. Results: The mean age was 55.5 years, 88% patients were male and 12% female. The pain was higher in patients operated with mesh. Conclusions: The inguinal hernia repair mesh group had less immediate postoperative complications and significantly earlier return to work than hernioplasty without mesh, this being one of the most important conclusions.

Authors: ROCHA Naruna Pereira , FORTES Renata Costa
Published: October 2015

Background: Early detection of changes in nutritional status is important for a better approach to the surgical patient. There are several nutritional measures in clinical practice, but there is not a complete method for determining the nutritional status, so, health professionals should only choose the best method to use. Aim: To evaluate the total lymphocyte count and albumin as predictors of identification of nutritional risk in surgical patients. Methods: Prospective longitudinal study was conducted with 69 patients undergoing surgery of the gastrointestinal tract. The assessment of nutritional status was evaluated by objective methods (anthropometry and biochemical tests) and subjective methods (subjective global assessment). Results: All parameters used in the nutritional assessment detected a high prevalence of malnutrition, with the exception of BMI which detected only 7.2% (n=5). The albumin (p=0.01), the total lymphocytes count (p=0.02), the percentage of adequacy of skinfolds (p<0.002) and the subjective global assessment (p<0.001) proved to be useful as predictors of risk of postoperative complications, since the smaller the values of albumin and lymphocyte count and higher the score the subjective global assessment were higher risks of surgical complications. Conclusions: A high prevalence of malnutrition was found, except for BMI. The use of albumin and total lymphocyte count were good predictor for the risk of postoperative complications and when used with other methods of assessing the nutritional status, such as the subjective global assessment and the percentage of adequacy of skinfolds, can be useful for identification of nutritional risk and postoperative complications.

Background : Obesity and type 2 diabetes mellitus are associated to inflammatory state, which can be set off by the adipose tissue, once it is a metabolically active organ that can cause a chronic mild inflammatory state. Aim : To evaluate the correlation between preoperative C-reactive protein and postoperative complications risk in obese patients (grades II and III) after Roux-en-Y gastric bypass, with and without type 2 diabetes mellitus. Methods : Between 2008 and 2013 were analysed 209 patients (107 with diabetes), presenting body mass index >40 kg/m2or >35 kg/m2with comorbidities. During the postoperative period, two groups were evaluated: with and without complications. Preoperative ultra-sensitive C-reactive protein was measured by immunonephelometry method. Results : Complications occurred in seven patients (pulmonary thromboembolism, fistula, two cases of suture leak, pancreatitis, evisceration and upper digestive hemorrhage). No statistical significance was found regarding lipid profile and C-reactive protein between patients with and without type 2 diabetes mellitus. When compared to each other, both groups (with and without complications) presented with statistical significance regarding C-reactive protein level (7,2 mg/dl vs 3,7 mg/dl, p=0,016) and had similar weight loss percentage after 3, 6 and 12 months follow-up. Conclusions : Preoperative C-reactive protein serum level was higher in the group which presented complications after Roux-en-Y gastric bypass when compared to the group without postoperative complications.
