Hyper-Production: A New Metric of Multifunctionality
Authors: Brouder Patrick , Karlsson Svante , Lundmark Linda
Published: October 2015

Multifunctionality has emerged as the dominant framework for understanding rural socioeconomic landscapes. The central claim of multifunctionality - that rural regions need to be understood as being made up of more than just traditional uses - has led to the incorporation of new rural activities into regional development plans, e.g., tourism. In some places, such post-productive activity is perceived to be slowly replacing productive uses of the land, e.g., agriculture/forestry. However, there is limited empirical evidence to support such claims. Drawing on previous research and data from the Swedish countryside this paper shows that, even as the number of persons employed within traditional activities decreases, the economic output per areal unit and per labour hour is increasing over time and traditional uses still occupy the majority of rural space. Hyper-production is introduced as a new metric for understanding multifunctional regions going forward. The complementary union of economic mainstays, such as agriculture, and newer activities with more quality-of-life benefits, such as tourism, is highlighted in terms of economic diversification, job creation and local social capital development, while the conflict-prone intersection of these two modes is also acknowledged. Understanding hyper-production as a key metric of multifunctionality is thus argued as integral to planning and developing resilient rural regions now and for the future.
Comparison of Mechanical Properties ofFiber-Reinforced Sand under Triaxial Compressionand Direct Shear
Authors: Noorzad Reza , Zarinkolaei Seyed Taher Ghoreyshi
Published: October 2015

This research investigates the behavior of sandreinforced with polypropylene fiber. To do this, 40 directshear tests and 40 triaxial tests were performed on thecoastal beaches of Babolsar, a city in the North of Iran. Theeffect of parameters such as fiber content, length of fiberand normal or confining pressure on the behavior of Babolsarsand have been studied. In this study, four various fibercontents (0, 0.25, 0.5 and 1 percent), three different lengthsof fiber (6, 12 and 18 mm) and four normal or confiningpressures (50, 100, 200 and 400 kPa) have been employed.The test results show that fiber inclusion has a significanteffect on the behavior of sand. In both direct shear and triaxialtests, the addition of fibers improved shear strengthparameters (C, '), increased peak shear strength and axialstrain at failure, and also limited the amount of post-peakreduction in shear resistance. The comparison of the testresults revealed that due to better fiber orientation towardthe direction of principal tensile strain in triaxial test ascompared to direct shear tests, the fiber efficiency and itseffect on soil behavior is much more significant in triaxialspecimens.
Geochemistry of amphibolites and related graphitic gneisses from the Suchý and Malá Magura Mountains (central Western Carpathians) – evidence for relics of the Variscan ophiolite complex
Authors: Ivan Peter , Méres Štefan
Published: October 2015

Three small bodies of amphibolites and associated graphitic gneisses from the Suchý and Malá Magura Mountains (Tatric Megaunit, central Western Carpathians) have been studied by petrographic and geochemical methods. Isolated, fault-bounded bodies first hundreds of meters in size are located in the complex of the Early Paleozoic paragneisses and migmatites intruded by the Lower Carboniferous granitoid rocks. Amphibolites (locally actinolite schists) were formed from effusive basalts, dolerites or isotropic gabbros hydrothermally altered and veined before the regional metamorphic transformation. Distribution of the trace elements relatively immobile during the metamorphic alteration (HFSE, REE, Cr, V, Sc) is similar to E-MORB type in the Malá Magura Mountain or to N-MORB/E-MORB types in the Suchý Mountain. Graphitic gneisses to metacherts are rich in silica (up to 88 wt. %) and Ctot, poor in other major element contents and display negative Ce-anomaly, enrichment in HREE, V, Cr and U. They were probably originally deposited as non-carbonate and silica-rich deep-sea sediments in anoxic conditions. The oceanic provenance of amphibolites and related graphitic gneisses clearly indicates their oceanic crust affinity and identity with the uppermost part of the ophiolite sequence. Ophiolite bodies from the Suchý and Malá Magura Mountains are supposed to be relic fault blocks identical with the Upper Devonian Pernek Group which represents a Variscan ophiolite nappe preserved to large extent in the Malé Karpaty Mountains located in the Tatric Megaunit further to the southwest. All these ophiolite relics are vestiges of the original ophiolite suture created by oceanic closure in the Lower Carboniferous.
Design and Testing of the Strain Transducer for Measuring Deformations of Pipelines Operating in the Mining-deformable Ground Environment
Authors: Gawedzki Waclaw , Tarnowski Jerzy
Published: October 2015

Design and laboratory test results of the strain transducer intended for monitoring and assessing stress states of pipelines sited in mining areas are presented in this paper. This transducer allows measuring strains of pipelines subjected to external forces - being the mining operations effect. Pipeline strains can have a direct influence on a tightness loss and penetration of the transported fluid into the environment. The original strain gauge transducer was proposed for performing measurements of strains. It allows measuring circumferential strains and determining the value and direction of the main longitudinal strain. This strain is determined on the basis of measuring component longitudinal strains originating from axial forces and the resultant bending moment. The main purpose of investigations was the experimental verification of the possibility of applying the strain transducer for measuring strains of polyethylene pipelines. The obtained results of the transducer subjected to influences of tensile and compression forces are presented and tests of relaxation properties of polyethylene are performed.
Novel Method for Sizing Metallic Bottom Crack Depth Using Multi-frequency Alternating Current Potential Drop Technique
Authors: Li Yuting , Gan Fangji , Wan Zhengjun , Liao Junbi , Li Wenqiang
Published: October 2015

Potential drop techniques are of two types: the direct current potential drop (DCPD) technique and alternating current potential drop (ACPD) technique, and both of them are used in nondestructive testing. ACPD, as a kind of valid method in sizing metal cracks, has been applied to evaluate metal structures. However, our review of most available approaches revealed that some improvements can be done in measuring depth of metal bottom crack by means of ACPD, such as accuracy and sensitivity of shallow crack. This paper studied a novel method which utilized the slope of voltage ratio-frequency curve to solve bottom crack depth by using a simple mathematic equation based on finite element analysis. It is found that voltage ratio varies linearly with frequency in the range of 5-15 Hz; this range is slightly higher than the equivalent frequency and lower than semi-permeable frequency. Simulation and experiment show that the novel method can measure the bottom crack depth accurately.

Model for Determining the Stability of Retail Deposits with Higher Outflow Rates / Model za izračun stabilnosti vlog na drobno z višjo stopnjo odliva
Authors: Murks Bašič Aleksandra
Published: October 2015

Retail deposits are treated as one of the cheapest and most stable funding sources for banks, especially for those with high volumes of retail deposits. A bank defines three main categories of retail deposits that are subject to different outflow rates for the purpose of liquidity coverage requirements in reporting and compliance. The outflow rates for the first two main groups are 5% and 10% respectively, but for the third main group the bank calculates its own outflow rates. We analyzed the latter in this paper. Each bank should assign retail deposits to one of the three categories based on the number and type of predetermined risk factors. Risk factors are divided into two groups according to the degree of risk. The paper first describes the legislative framework, followed by the method of calculating higher outflow rates for retail deposits according to the historical movements and the expected volatility assessment in the situation of stress conditions. At the end of the paper, we briefly provide the future treatment of retail deposits with higher outflow rates.
Adolescent personalities and their self-acceptance within complete families, incomplete families and reconstructed families
Authors: Walęcka-Matyja Katarzyna
Published: October 2015

At the time of this work I had been concentrating on how the family gave shape to adolescent personalities and how adolescents would, as a consequence, accept themselves.

The purpose of this present study is to determine the differences in personality range and levels of self-acceptance among groups of women and men from complete, incomplete and reconstructed families. The study included a group of 314 adolescents, from the administrative region of Lódź. The following test methods were used: the Survey and standardised Inventory of Personality NEO - FFI by P.T. Costa and R. McCrae as adapted by B. Zawadzki, J. Strelau, P. Szczepaniak and M. Śliwińska; and the Scale of Interpersonal Attitude (SUI) as adapted by J. M. Stanik.

As a result of statistical analyses, it turned out that the dimension of personality the Openness to Experience had indeed diversified the examined adolescent groups. Statistically significant differences were also observed at the self-acceptance level between the study groups.
Internal relationship patterns in borderline and neurotic personality organization: An analysis of self-narratives
Authors: Soroko Emilia
Published: October 2015

The main goals of this study are 1) to explore whether internal relationship patterns are related to personality organization, and 2) to recognize the role that selected relationship patterns play in diagnosing personality organization levels. Internal relationship patterns were assessed according to the core conflictual relationship theme (CCRT) - about wishes (WS), responses from others (RO), and responses of the self (RS) - as identified from participants’ self-narratives about important relationships. Significant differences in the frequencies of patterns were found among participants with borderline personality organization (BPO), neurotic personality organization (NPO), and integrated personality (IPO). For example, the majority of negative RS responses were detected in the BPO sample. The study supports the thesis that relationship patterns might be related to personality organization, and that object representation complexity may be a good predictor of integrated personality organization.
The nestling – waiting for adulthood?
Authors: Bartosz Bogna , Lewandowska Agata , Antczak Iga
Published: October 2015

Our article deals with the problem of ‘nestlings’ - young adults who postpone the moment of entering adulthood. A brief review of data and research results indicates that delays in undertaking developmental tasks typical of adulthood refer to a professional job, starting a family or a relationship, and gaining independence (not only financially). We discuss cultural, economic and psychological contexts of nestling, and attempt to answer the question whether waiting for adulthood is a global problem or a problem specific to only certain countries or just to Poland. It seems necessary to undertake research on this phenomenon. Nestling ought to be explored not only from the adult child’ perspective but from the parental perspective as well.

Use of Internet and its Addictive risk among Polish students – comparative analysis over a seven-year period
Authors: Dembińska Aleksandra , Ochnik Dominika
Published: October 2015

Our study reveals the psychosocial changes occurring in Polish students on the Internet in the last seven years. The study comprised two stages (2005 and 2012). The analyses indicated that while the Internet’s intense use has lowered, the factors facilitating Internet risk addiction have become more pronounced. Such risk factors are: the manner of using the Internet (entertainment, pornography); relationships in the cyber community; and time spent online (the more time spent, the greater the risk of addiction). The lower the self-esteem the higher the risk of addiction. However, the percentage of people with Internet addiction symptoms has remained static.
Generic and Specific Numeral Classifier Input and its Relation to Children’s Classifier and Number Learning
Authors: Atagi Natsuki , Sandhofer Catherine M.
Published: October 2015

In Japanese, numeral classifiers-or measure words-co-occur with numbers in counting phrases. Th e present study characterized parent numeral classifier use and its relation to children’s classifier acquisition and number learning. Twenty-four Japanese-speaking parents and their two- to six-year-old children viewed and talked about two wordless picture books about counting to each other. Children also participated in a Counting task and Give-N task. Results revealed (1) parents’ classifier use changed in relation to children’s age and classifier use, and (2) parents’ increased use of specific classifiers was uniquely associated with children’s number understanding. These results suggest that aspects of children’s language and numerical development are related to parents’ language input, demonstrating the importance of examining the relation between language and cognition in a developmental context.
Pneumatology and Politics: The role of the Holy Spirit in the articulation of an Orthodox political theology
Authors: Asproulis Nikolaos
Published: October 2015

In this paper an attempt is made to discuss the importance of the Holy Spirit in the development of an Orthodox political theology, by bringing into critical dialogue the recent contributions of two of the most known Orthodox theologians of the young generation, namely A. Papanikolaou and P. Kalaitzidis. It is commonly recognized that the Holy Spirit is closely related both to the very “constitution of the whole Church” in virtue of the Eucharistic event, as well as to the everyday charismatic lives of individual Christians due to the various forms or stages of ascetism. In this respect a careful comparative examination of these two important works, would highlight some invaluable elements (Eucharistic perspective, eschatological orientation, historical commitment, ethical action, open and critical dialogue with modernity etc.) toward a formulation of a comprehensive and urgently necessary political theology. This sort of political theology should have inevitable implications for the Christian perception of the communal and the individual ecclesial life. This “theo-political” program proposed by the two thinkers and founded on a robust Pneumatology, could be perfectly included, following the apostolic kerygma and the patristic ethos, into a new way of doing (Orthodox) Christian theology, that takes as its starting point the grammar of the self-Revelation of God in the ongoing history of salvation (“Church and World Dogmatics”).
An attempt to define the charismata in the main Christian traditions
Authors: Ştefănică Dragoș
Published: October 2015

The aim of the present article is to analyse the way in which the main Christian traditions define the charismata, or the gifts of the Holy Spirit. As we shall see, the definitions provided by the Catholic, the Eastern Orthodox or the Reformed Theologies are very broad, while in Pentecostal theology charismata have a rather technical meaning. Finally, we will observe that a good clarification of the concepts in question could help the development of the interfaith theological dialogue, from the pneumatological point of view.
The Importance of Small Change
Authors: Langin Katie
Published: October 2015

While conducting research on Santa Cruz Island off the coast of California, Langin found differences in the beaks of a single species of bird, the endemic island scrub-jay. Though they lived in neighboring habitats, the size and shape of the birds’ beaks change depending on the types of flora available to them. The discovery is one of several recent examples of microgeographic divergence that point to greater biodiversity than biologists had come to expect.
Seeing Evolution
Authors: Linhart Yan
Published: October 2015

California is an excellent setting to observe evolution in action. Tough, flavorless tomatoes bred for supermarkets provide an example of rapid human-induced evolutionary change in a crop plant, while many California landscapes exert specific ecological pressures that have shaped their resident species for millennia. These settings include the Central Valley, the Sierra Nevada, and archipelagoes of habitat islands. A better understanding of evolution in California is necessary to inform the management of our agricultural ecosystems and conservation of our natural landscapes and the species that depend on them, many of which face uncertain futures because of human activities and climate change.
The Origins of Big Science
Authors: Hiltzik Michael
Published: October 2015

Ernest Lawrence’s invention of the cyclotron in Berkeley more than eighty years ago did more than introduce a uniquely efficient and effective atom-smasher to the world of high-energy physics; it launched the paradigm of capital-intensive, large-team research known as “Big Science.” The paradigm’s offspring include the Manhattan Project, the moon landings, the Human Genome Project, and research into climate change. But it raises questions about the influence of money on basic research and how society should weigh competing demands for resources among practical social needs and the quest for fundamental knowledge of our natural world.

Unexpected features and mechanism of heterodimer formation of a herpesvirus nuclear egress complex

Published: October 2015

Herpesvirus nucleocapsids escape from the nucleus in a process orchestrated by a highly conserved, viral nuclear egress complex. In human cytomegalovirus, the complex consists of two proteins, UL50 and UL53. We solved structures of versions of UL53 and the complex by X‐ray crystallography. The UL53 structures, determined at 1.93 and 3.0 Å resolution, contained unexpected features including a Bergerat fold resembling that found in certain nucleotide‐binding proteins, and a Cys3His zinc finger. Substitutions of zinc‐coordinating residues decreased UL50–UL53 co‐localization in transfected cells, and, when incorporated into the HCMV genome, ablated viral replication. The structure of the complex, determined at 2.47 Å resolution, revealed a mechanism of heterodimerization in which UL50 clamps onto helices of UL53 like a vise. Substitutions of particular residues on the interaction interface disrupted UL50–UL53 co‐localization in transfected cells and abolished virus production. The structures and the identification of contacts can be harnessed toward the rational design of novel and highly specific antiviral drugs and will aid in the detailed understanding of nuclear egress.
A Gene Regulatory Program in Human Breast Cancer
Authors: Li Renhua , Campos John , Iida Joji
Published: October 2015

Molecular heterogeneity in human breast cancer has challenged diagnosis, prognosis, and clinical treatment. It is well known that molecular subtypes of breast tumors are associated with significant differences in prognosis and survival. Assuming that the differences are attributed to subtype-specific pathways, we then suspect that there might be gene regulatory mechanisms that modulate the behavior of the pathways and their interactions. In this study, we proposed an integrated methodology, including machine learning and information theory, to explore the mechanisms. Using existing data from three large cohorts of human breast cancer populations, we have identified an ensemble of 16 master regulator genes (or MR16) that can discriminate breast tumor samples into four major subtypes. Evidence from gene expression across the three cohorts has consistently indicated that the MR16 can be divided into two groups that demonstrate subtype-specific gene expression patterns. For example, group 1 MRs, including ESR1, FOXA1, and GATA3, are overexpressed in luminal A and luminal B subtypes, but lowly expressed in HER2-enriched and basal-like subtypes. In contrast, group 2 MRs, including FOXM1, EZH2, MYBL2, and ZNF695, display an opposite pattern. Furthermore, evidence from mutual information modeling has congruently indicated that the two groups of MRs either up- or down-regulate cancer driver-related genes in opposite directions. Furthermore, integration of somatic mutations with pathway changes leads to identification of canonical genomic alternations in a subtype-specific fashion. Taken together, these studies have implicated a gene regulatory program for breast tumor progression.
Escape from Mitotic Arrest: An Unexpected Connection Between Microtubule Dynamics and Epigenetic Regulation of Centromeric Chromatin in Schizosaccharomyces pombe
Authors: George Anuja A , Walworth Nancy C
Published: October 2015

Accurate chromosome segregation is necessary to ensure genomic integrity. Segregation depends on the proper functioning of the centromere, kinetochore, and mitotic spindle microtubules and is monitored by the spindle assembly checkpoint (SAC). In the fission yeast Schizosaccharomyces pombe, defects in Dis1, a microtubule-associated protein that influences microtubule dynamics, lead to mitotic arrest as a result of an active SAC and consequent failure to grow at low temperature. In a mutant dis1 background (dis1-288), loss of function of Msc1, a fission yeast homolog of the KDM5 family of proteins, suppresses the growth defect and promotes normal mitosis. Genetic analysis implicates a histone deacetylase (HDAC)–linked pathway in suppression because HDAC mutants clr6-1, clr3∆, and sir2∆, though not hos2∆, also promote normal mitosis in the dis1-288 mutant. Suppression of the dis phenotype through loss of msc1 function requires the spindle checkpoint protein Mad2 and is limited by the presence of the heterochromatin-associated HP1 protein homolog Swi6. We speculate that alterations in histone acetylation promote a centromeric chromatin environment that compensates for compromised dis1 function by allowing for successful kinetochore-microtubule interactions that can satisfy the SAC. In cells arrested in mitosis by mutation of dis1, loss of function of epigenetic determinants such as Msc1 or specific HDACs can promote cell survival. Because the KDM5 family of proteins has been implicated in human cancers, an appreciation of the potential role of this family of proteins in chromosome segregation is warranted.

Published: October 2015

ABSTRACT This article presents a comparative study among people with cerebral palsy and healthy controls, of various ages, using a Brain-computer Interface (BCI) device. The research is qualitative in its approach. Researchers worked with Observational Case Studies. People with cerebral palsy and healthy controls were evaluated in Portugal and in Brazil. The study aimed to develop a study for product evaluation in order to perceive whether people with cerebral palsy could interact with the computer and compare whether their performance is similar to that of healthy controls when using the Brain-computer Interface. Ultimately, it was found that there are no significant differences between people with cerebral palsy in the two countries, as well as between populations without cerebral palsy (healthy controls).
Olfaction in the fruit-eating bats Artibeus lituratus and Carollia perspicillata: an experimental analysis
Authors: Parolin Lays C. , Mikich Sandra B. , Bianconi Gledson V.
Published: October 2015

ABSTRACT Studies suggest that frugivorous bats search and select fruit mainly by olfaction so that they can be attracted by smell alone. The aim of this study was to evaluate, in captivity, the behavioural response (number of foraging attempts) of Artibeus lituratus and Carollia perspicillata offered essential oils extracted from ripe fruit of Ficus insipida (Moraceae) and Piper hispidum (Piperaceae) as well as intact fruit wrapped in gauze to attract bats with reduced visual stimuli. Based on previous reports, we hypothesized that A.lituratus would exhibit preference for Ficus fruits/oil while C. perspicillata would prefer Piper fruit/oil. Four arrangements of these attractants were tested in triplicate: P. hispidum fruit vs. F. insipida fruit, P.hispidum oil vs. F. insipida oil, P. hispidum oil vs. F. insipida fruit and P. hispidum fruit vs. F. insipida oil. As expected, in all tests, A. lituratus showed the highest number of foraging attempts in F. insipida while C. perspicillata in those of P. hispidum. Based on the number of foraging attempts both species exhibited a positive response to their favorite fruit genera, though the differences were not always statistically significant. The results confirm the importance of smell in fruit choice by these species.
Coral-based climate records from tropical South Atlantic: 2009/2010 ENSO event in C and O isotopes from Porites corals (Rocas Atoll, Brazil)

Published: October 2015

ABSTRACT Coral skeletons contain records of past environmental conditions due to their long life span and well calibrated geochemical signatures. C and O isotope records of corals are especially interesting, because they can highlight multidecadal variability of local climate conditions beyond the instrumental record, with high fidelity and sub-annual resolution. Although, in order to get an optimal geochemical signal in coral skeleton, sampling strategies must be followed. Here we report one of the first coral-based isotopic record from the Equatorial South Atlantic from two colonies of Porites astreoides from the Rocas Atoll (offshore Brazil), a new location for climate reconstruction. We present time series of isotopic variation from profiles along the corallite valley of one colony and the apex of the corallite fan of the other colony. Significant differences in the isotopic values between the two colonies are observed, yet both record the 2009/2010 El Niño event - a period of widespread coral bleaching - as anomalously negative δ18O values (up to −1 permil). δ13C is found to be measurably affected by the El Niño event in one colony, by more positive values (+0.39 ‰), and together with a bloom of endolithic algae, may indicate physiological alteration of this colony. Our findings indicate that corals from the Rocas Atoll can be used for monitoring climate oscillations in the tropical South Atlantic Ocean.

AbstractIntroduction Central instability is associated with insufficient endurance and strength of the stabilizer muscles, and it can lead to muscle imbalance and injuries.Objective Relate side bridge performance with the presence of injuries in amateur soccer athletes.Materials and methods A cross-sectional study with a sample of 188 male athletes, aged between 11 and 17 years. To identify the injuries, a questionnaire developed by researchers was applied and the players’ clinical records were reviewed. The time of the side bridge test was used to identify muscle imbalance. For statistical analysis, the following tests were used: chi-square test; Pearson’s chi-square test; Fisher’s exact test; Yates’s correction for continuity; two-way ANOVA; one-way ANOVA; and t-test. The significance level (α) of 5% was adopted.Results Injuries were reported by 59.6% of the athletes: sprain (31.3%); muscle strain (28.6%) and fracture; luxation and subluxation (19.6%) were the most frequently reported injuries. Athletes that reported any injury corresponded to 73.2% of the sample. The presence of injuries was not associated with muscle imbalance (p = 0.565), as it prevailed in athletes with both balance (64%) and imbalance (58%). Injury type and prevalence were not significant when compared with the presence of imbalance (p > 0.05).Final considerations No significant relation between muscle imbalance and injury was observed in the studied sample.

Published: October 2015

AbstractIntroduction The health locus of control is defined as the perception of individuals in relation to whom they believe to be responsible for their health condition, including low back pain.Objective To identify whether individuals suffering from chronic low back pain in active physical therapy treatment believe they are responsible for their own condition.Material and methods Cross-sectional study involving 28 patients under active physical therapy treatment for non-specific chronic low back pain. Sociodemographic data and low back characteristics — including disability and pain severity — were collected. The Multidimensional Health Locus of Control (MHLC) scale was used to assess the health locus of control.Results Participants undergoing active low back pain treatment presented a mean (SD) of 26 points (11.40) in a 0–100 point scale for disability and 6.39 points (2.24) on a 0–10 scale for pain. In relation to the health locus of control, the means (SD) for internal, external and chance subscales were, respectively: 29.32 (3.98), 24.75 (3.58), and 13.71 (6.67). 82.1% of the participants presented higher rates for internal locus of control.Conclusion Patients undergoing active treatment for chronic low back pain believe they are responsible for their own condition. Further longitudinal studies may determine whether active treatments affect the beliefs of low back pain patients.

Published: October 2015

AbstractIntroduction Prevention of occupational diseases depends on the identification of risk factors, which can be complemented by the functional assessment of workers.Objective The aim of this study was to develop a postural and ergonomic assessment tool for the analysis of subjects’ sitting posture at the computer workstation.Materials and methods This is a quantitative, descriptive, observational, cross-sectional study. Eighty-two employees in the administrative sector of FIERGS were invited to participate in the study. The mean age was 32.8 ± 7.7 years. The IAPE (Instrumento de Avaliação Postural Ergonômica [Postural and Ergonomic Assessment Tool]) development and administration process was performed in four stages: 1) observation of the most commonly adopted postures by employees in the workplace; 2) development of the first version of the IAPE; 3) content validation by two ergonomics experts and content validity index (CVI) calculation; 4) inter-evaluator reproducibility assessment. Reproducibility was assessed by Wilcoxon test and intraclass correlation coefficient (ICC) (p < 0.05).Results The results obtained from the calculation of the CVI showed that the IAPE possesses a high degree of content validity (CVI = 1). Inter-evaluator reproducibility assessment showed no differences between evaluators (p < 0.05) and ICC values above 0.80 (p < 0.05). This shows an adequate inter-evaluator reproducibility of the tool.Conclusion Based on the results of the IAPE development process, it can be concluded that the tool has content validity and adequate inter-evaluator reproducibility. This tool can aid in the development of occupational disease prevention and health promotion strategies.

AbstractObjective To verify the behavior of anthropometric, cardiovascular and functional variables as indicators of health-related physical fitness in university professors and perform a comparison of these variables between sexes.Materials and methods We conducted an observational epidemiological cross-sectional study in 145 professors (45.86 ± 9.7 years), 103 men (71.03%), which were evaluated by measuring heart rate (HR) and systolic (SBP) and diastolic (DBP) pressure at rest, body weight, height, body mass index (BMI), body fat percentage (BF%), handgrip strength (HGS), flexibility and cardiorespiratory fitness (CRF). We proceeded to the descriptive analysis, Student t-test for comparison between sexes and multiple regression analysis to verify the association between the variables analyzed. It was adopted a significance level of p < 0.05.Results The sex affected all variables. Women had better levels of BMI, flexibility, SBP and DBP. The BF% and CRF were associated with SBP and BMI in both sexes.Conclusion The behavior of anthropometric, cardiovascular and functional variables indicated unsatisfactory values for flexibility, HGS and BMI, with the worst levels among men. Furthermore, the variables that showed better association with HRPF were BF% and CRF.

ResumoIntroduçãoO hipoclorito de sódio é a substância química auxiliar do tratamento endodôntico mais utilizada devido à sua ação antimicrobiana e à sua capacidade de dissolver matéria orgânica.ObjetivoO objetivo do presente estudo foi comparar a velocidade de dissolução de fragmentos de tecido pulpar bovino em diferentes concentrações de hipoclorito de sódio.Material e métodoFragmentos de tecido pulpar bovino, com peso determinado, foram imersos em 20 mL de hipoclorito de sódio, em frascos de Becker colocados em uma incubadora/agitadora. Foram testadas as concentrações de 1%, 2,5% e 5%, com pH 11, a 36°C. As amostras foram avaliadas visualmente durante a agitação, com auxílio de lupa, até sua completa dissolução. A velocidade de dissolução de cada fragmento foi determinada em miligramas por minuto e a velocidade média de cada grupo, analisada pelos métodos estatísticos de Kruskal-Wallis e Dunn's Multiple.ResultadoHouve diferença estatisticamente significante entre a concentração de 1%, que apresentou a menor velocidade, e as demais.ConclusãoA velocidade de dissolução do hipoclorito de sódio, nas concentrações testadas, se torna mais rápida com o aumento da concentração.

ResumoIntroduçãoAgentes promotores de ligações cruzadas têm sido investigados como inibidores da atividade enzimática da dentina, o que favoreceria a longevidade das restaurações adesivas.ObjetivoAvaliar o efeito do tratamento da dentina com proantocianidina (PA), em curtos períodos de tempo, na inibição da atividade de MMPs in situ.Material e métodoQuarenta espécimes de dentina (1×1×6 mm) foram obtidos de molares hígidos e divididos em quatro grupos (n=10). Os espécimes foram condicionados com ácido fosfórico por 15 s, seguido de lavagem em água deionizada. A dentina condicionada foi tratada com: água, 5% PA por 5 s, 15 s ou 30 s. A atividade de MMP foi analisada colorimetricamente (SensoLyte®) e os dados de absorbância (412 nm) foram submetidos aos testes de ANOVA e Tukey (α=0,05).ResultadoTodos os períodos de tratamento foram capazes de reduzir a atividade de MMPs, sendo que os melhores resultados foram observados para a dentina tratada com PA por 15 s (63,1% redução) e 30 s (70,2%). O tratamento por 5 s foi capaz de inibir 39,9% das MMPs.ConclusãoA aplicação de PA sobre a dentina condicionada foi capaz de reduzir a atividade de MMPs mesmo em períodos de tempo extremamente curtos, como 5 s. No entanto, melhores resultados foram obtidos com os maiores períodos de tratamento.

AbstractIntroductionThe increase in prison populations is a phenomenon which is systematically rising throughout the world, leading to overcrowding of prisons, which has direct consequences on the health conditions of the individuals.ObjectiveTo explore the relationship among oral health, the life path and the perception of subjects in a vulnerability context.Material and methodThis is a qualitative study, developed with inmates in a State Penitentiary. To obtain and process the data, individual interviews and the Thematic Content Analysis technique were used.ResultThe interviewees showed limited perception of the process of oral health and disease fostered by the experiences of relatives and by knowledge acquired in the street or from the media. The life path in prison seemed to have little influence on this understanding. However, the prison experience influenced the oral condition of the inmates by facilitating access to dental service, oral hygiene materials and the improvement in their health knowledge and habits. The oral health results presented were, generally, in agreement with so-called common sense and with studies developed in socially similar populations.ConclusionThus, considering the limitations imposed by the way data were collected, in prison and in a vulnerability context; a non-harmful influence on the condition studied regarding the oral health of inmates is suggested.

Em uma população de maxixe (Cucumis anguria. L.), representada por 64 progênies, foram esitimados alguns parâmetros, genéticos referentes à produção. A variância genética entre famílias (σp2) foi superior à variância ambiental (σp2), exceto pana peso médio de frutos. As herdabilidades (coeficiente de herdabilidade) baseadas em médias de famílias h2 foram estimadas em 79, 38%, 33,17% e. 71,00% respectivamente paro número pese e produção de frutos por planta. Os ganhos esperados com a seleção de 5% das melhores progênies, em relação à população original foi na ordem de 4,033%; 5,066% e 41,613%.0 estudo de correlações genotípicas e fenotípicas detectou valores altos e positivos para. número X produção e peso X produção. A seleção de plantas através do caráter, número de frutos ou frutos de maior peso deverá ser eficiente em melhorar a pnodução.

Foram analisadas e comparadas neste trabalho, quanto às qualidades físico-químicas, amostras de água de 29 (vinte e nove) afluentes do rio Negro, A maioria das águas e muito pobre em sais dissolvidos, e por outro lado bastante ácida, sendo observado que. as substâncias coloridas exercem influencia sobre algum parâmetros químicos isto bem demonstrado pelos resultados de coeficiente, de correlação a 5%. Os rios da margem esquerda provenientes das, montanhas localizadas ao norte são mais férteis em substâncias nutritivas minerais. Já os da margem direita, que em sua maioria nascem em terras alagadiças e em campinas, são considerados extremamente pobres. De um modo geral, são as condições físico-químicas e biológicas que influenciam os resultados de nitrogênio. Discute-se também a hipótese da fertilização de pequenas áreas inundáveis que atualmente estão de formando no baixo rio Negro, bem como o aparecimento de macrófitas aquáticas.
Aspectos biológicos de peixes amazônicos. III. Anatomia microscópica do esôfago, estômago e cecos pilóricos de Semaprochilodus insignis (characiformes : Prochilodontidae)
Authors: Chaves Paulo de Tarso da Cunha , Vazzoler Celso
Published: October 2015

Foi descrita a constituição histológica do esófago, estômago e cecos pilóricos de Semaprochilodus insignis, um Characiforma de expressiva ocorrência na Amazônia central, onde é usualmente conhecido como "jaraqui escama-grossa". As camadas epitelial e muscular mostraram-se bastante variáveis de órgão para órgão, e mesmo em diferentes segmentos de um único órgão. O epitélio do esôfago é inicialmente estratificado pavimentoso e finalmente simples mucoso. O estômago compõe-se de uma porção descendente, revestida por glândulas gástricas, e uma ascendente, não-glandular. A camada muscular nestes dois órgãos sofre substituição gradual da estriada para a lisa, bem como a orientação dos feixes. Os cecos pilóricos, pequenos e numerosos, não apresentam nem componentes glandulares, nem absortivos. Por fim, é sugerido um mecanismo geral para a digestão, considerando o hábito alimentar dessa espécie.

Durante um período de treze meses, de março de 1979 a março de 1980, excursões semanais foram realizadas ao Janauacá, um complexo de, l.agos de várzea da Amazônia Central. Miltrezentos e trinta e cinco peixesde cinco ordens, dezenove famílias e. oitenta espécies foram examinados, visando a determinar os índices naturais de infestação por crustáceos da subclasse Branchiura. Dos peixes examinados 11% estavam parasitados e apresentaram uma média de cinco crustáceos por peixe. Os maiores índices de infestação ocorreram nos Siluroides, 29% de prevalência e 18,5 de intensidade de infestação, seguidos pelos Characoides com 8,4% e 2,5. Os Perciformes apresentaram o terceiro maior índi.ce, 7,4% de. prevalência e 2,0 de intensidade de infestação. Os menores índices ocorreram nos Osteoglossiformes, 3,0% e 5,0 e nos Clupeiformes com 4,0% e 1,0. Durante o período de coletas, dezoito espécies de peixes não ocorreram parasitadas por branquiuras. Catorze espécies de branquiuros foram coletados no lago Janauacá. Alguns aspectos taxionómicos , biogeográficos e econômicos dos peixes são abordados
