Exploring the sources and mechanisms of cognitive errors in medical diagnosis with associative memory models
Authors: Pomi Andrés
Published: November 2017

Background:

One of the central challenges of third millennium medicine is the abatement of medical errors. Among the most frequent and hardiest causes of misdiagnosis are cognitive errors produced by faulty medical reasoning. These errors have been analyzed from the perspectives of cognitive psychology and empirical medical studies. We introduce a neurocognitive model of medical diagnosis to address this issue.

Methods:

We construct a connectionist model based on the associative nature of human memory to explore the non-analytical, pattern-recognition mode of diagnosis. A context-dependent matrix memory associates signs and symptoms with their corresponding diseases. The weights of these associations depend on the frequencies of occurrence of each disease and on the different combinations of signs and symptoms of each presentation of that disease. The system receives signs and symptoms and by a second input, the degree of diagnostic uncertainty. Its output is a probabilistic map on the set of possible diseases.

Results:

The model reproduces different kinds of well-known cognitive errors in diagnosis. Errors in the model come from two sources. One, dependent on the knowledge stored in memory, varies with the accumulated experience of the physician and explains age-dependent errors and effects such as epidemiological masking. The other is independent of experience and explains contextual effects such as anchoring.

Conclusions:

Our results strongly suggest that cognitive biases are inevitable consequences of associative storage and recall. We found that this model provides valuable insight into the mechanisms of cognitive error and we hope it will prove useful in medical education.
U-Pb geochronology, Sr-Nd geochemistry, petrogenesis and tectonic setting of Gandab volcanic rocks, northeastern Iran

Published: November 2017

This paper addresses U-Pb geochronology, Sr-Nd geochemistry, petrogenesis and tectonic setting in the Gandab volcanic rocks. The Gandab volcanic rocks belong to the Sabzevar zone magmatic arc (northeastern Iran). Petrographically, all the studied volcanic rocks indicate porphyritic textures with phenocrysts of plagioclase, K-feldespar, hornblende, pyroxene, and magnetite which are embedded in a fine to medium grained groundmass. As well, amygdaloidal, and poikilitic textures are seen in some rocks. The standard chemical classifications show that the studied rocks are basaltic trachy andesite, trachy andesite, trachyte, and trachy dacite. Major elements reveal that the studied samples are metaluminous and their alumina saturation index varies from 0.71 to 1.02. The chondrite-normalized rare earth element and mantle-normalized trace element patterns show enrichment in light rare earth elements (LREE) relative to heavy rare earth elements (HREE) and in large ion lithophile elements (LILE) relative to high field strength elements (HFSE). As well they show a slightly negative Eu anomaly (Eu/Eu* = 0.72 – 0.97). The whole-rock geochemistry of the studied rocks suggests that they are related to each other by fractional crystallization. LA-MC-ICP-MS U-Pb analyses in zircon grains from two volcanic rock samples (GCH-119 and GCH-171) gave ages ranging of 5.47 ± 0.22 Ma to 2.44 ± 0.79 Ma, which corresponds to the Pliocene period. In four samples analysed for Sr and Nd isotopes 87Sr/86Sr ratios range from 0.704082 to 0.705931 and εNd values vary between +3.34 and +5. These values could be regarded to as representing mantle derived magmas. Taking into account the comparing rare earth element (REE) patterns, an origin of the parental magmas in enriched lithospheric mantle is suggested. Finally, it is concluded that Pliocene Gandab volcanic rocks are related to the post-collision environment that followed the Neo-Tethys subduction.
Absolute chronology of the Zedmar culture: Re-thinking radiocarbon dates
Authors: Kozicka Magdalena
Published: November 2017

The Zedmar culture is linked with the subneolithic circle of the South-Eastern Baltic region. So far, excavations have been carried out only on seven archaeological sites. Nonetheless, there are quite a lot of radiocarbon measurements. Most of them refer to the stratigraphic contexts. This allows to integrate all of the data into statistical models. With these, it is possible to query some statements about the Zedmar culture origin and its duration. At least as long as placing the Zedmar culture into an absolute timescale may offer any solution to those issues.

The idea that radiocarbon dates could provide solutions or even final answers to some arguable questions in prehistorical studies was dropped, as soon as it became clear that in the whole approach the key role is played by calibration methods and the general variability of sampled material.

However – thanks to including Bayesian analysis, a better understanding of dated materials and more complex examination of received results – it has been asserted again.

Published: November 2017

In this study, a simulation analysis of 40-Gb/s long-haul (120 km) dense wavelength-division multiplexer system (DWDM) of 32 channels with 50 GHz spacing is conducted for duobinary return-to-zero modulation formats. Pre- and post-dispersion compensation schemes utilizing dispersion compensating fiber (DCF) and fiber Bragg grating (FBG) are analyzed to compare these schemes at high bit rate. Quality factor (Q) and bit error rate (BER) values are used to measure the response of the system as a function of input power for both compensation schemes. The pre-FBG scheme shows a better performance in terms of Q-factor that reached 11.5 at 0 dBm input signal power.

Tracking Sustainable Development in Politically Violent Zones: Need for Framework and Cognizance-Kashmir in Context
Authors: Aabid Mohmad , Farooq Aadil
Published: November 2017

As a conceptual framework, Sustainable Development (SD) intends to improve current Well-Being, while preserving or maintaining the basis for future Well-Being (Solow, 1991). In order to measure Sustainable Development various indicators were chosen, among which health has been considered as an important indicator. As a result, we see a huge focus on health in Sustainable Development frameworks. But, the emphasis of frameworks has been only on the physical and epidemiological factors affecting the health. In contrary, in context of a highly political turmoil zone, it is the psychological well-being that is severely affected. This component of health i.e., psychological well-being is neglected to find a significant place in Sustainable Development frameworks. Since, these frameworks are crucial for national level policy making and it is likely that policies formulated on such frameworks may not replicate the same successful results in every context (such as in Armed Conflict). With such understanding in the background, this paper will show the need to focus on mental health in armed conflict situations in Sustainable Development frameworks. This paper will attempt to show how ignoring mental health in armed conflict situations impede development. The need to develop a holistic framework which focuses on mental health in Armed Conflict situations will be highlighted in context of Kashmir.
Air pollution engineering
Authors: Maduna Karolina , Tomašić Vesna
Published: November 2017

Air pollution is an environmental and a social problem which leads to a multitude of adverse effects on human health and standard of human life, state of the ecosystems and global change of climate. Air pollutants are emitted from natural, but mostly from anthropogenic sources and may be transported over long distances. Some air pollutants are extremely stable in the atmosphere and may accumulate in the environment and in the food chain, affecting human beings, animals and natural biodiversity. Obviously, air pollution is a complex problem that poses multiple challenges in terms of management and abatements of the pollutants emission. Effective approach to the problems of air pollution requires a good understanding of the sources that cause it, knowledge of air quality status and future trends as well as its impact on humans and ecosystems. This chapter deals with the complexities of the air pollution and presents an overview of different technical processes and equipment for air pollution control, as well as basic principles of their work. The problems of air protection as well as protection of other ecosystems can be solved only by the coordinated endeavors of various scientific and engineering disciplines, such as chemistry, physics, biology, medicine, chemical engineering and social sciences. The most important engineering contribution is mostly focused on development, design and operation of equipment for the abatement of harmful emissions into environment.
Synthesis meets theory: Past, present and future of rational chemistry
Authors: Fianchini Mauro
Published: November 2017

Chemical synthesis has its roots in the empirical approach of alchemy. Nonetheless, the birth of the scientific method, the technical and technological advances (exploiting revolutionary discoveries in physics) and the improved management and sharing of growing databases greatly contributed to the evolution of chemistry from an esoteric ground into a mature scientific discipline during these last 400 years. Furthermore, thanks to the evolution of computational resources, platforms and media in the last 40 years, theoretical chemistry has added to the puzzle the final missing tile in the process of “rationalizing” chemistry. The use of mathematical models of chemical properties, behaviors and reactivities is nowadays ubiquitous in literature. Theoretical chemistry has been successful in the difficult task of complementing and explaining synthetic results and providing rigorous insights when these are otherwise unattainable by experiment. The first part of this review walks the reader through a concise historical overview on the evolution of the “model” in chemistry. Salient milestones have been highlighted and briefly discussed. The second part focuses more on the general description of recent state-of-the-art computational techniques currently used worldwide by chemists to produce synergistic models between theory and experiment. Each section is complemented by key-examples taken from the literature that illustrate the application of the technique discussed therein.

Published: November 2017

A new method for constructing the multi-modal impacts on the immune systemin the chronic phase of viral infection, based on mathematical models formulated with delay-differential equations is proposed. The so called, optimal disturbances, widely used in the aerodynamic stability theory for mathematical models without delays are constructed for perturbing the steady states of the dynamical system for maximizing the perturbation-induced response. The concept of optimal disturbances is generalized on the systems with delayed argument. An algorithm for computing the optimal disturbances is developed for such systems. The elaborated computational technology is tested on a system of four nonlinear delay-differential equations which represents the model of experimental infection in mice caused by lymphocytic choriomeningitis virus. The steady-state perturbations resulting in a maximum responsewere computed with the proposed algorithm for two types of steady states characterized by a low and a high levels of viral load. The possibility of correction of the infection dynamics and the restoration of virus-specific lymphocyte functioning of the immune system by perturbing the steady states is demonstrated.
Mechanical model of the left ventricle of the heart approximated by axisymmetric geometry
Authors: Syomin Fyodor A. , Tsaturyan Andrey K.
Published: November 2017

An axisymmetric model is suggested to simulate mechanical performance of the left ventricle of the heart. Cardiac muscle is treated as incompressible anisotropic material with active tension directed along muscle fibres. This tension depends on kinetic variables that characterize interaction of contractile proteins and regulation of muscle contraction by calcium ions. For numerical simulation of heartbeats the finite element method was implemented. The model reproduces well changes in ventricle geometry between systole and diastole, ejection fraction, pulse wave of ventricular and arterial pressure typical for normal human heart. The model also reproduces well the dependence of the stroke volume on end-diastolic and arterial pressures (the Frank–Starling law of the heart and Anrep effect). The results demonstrate that our model of cardiac muscle can be successfully applied to multiscale 3D simulation of the heart.
Code Calculations for Local Stability of Shaft Guides
Authors: Fiołek Przemysław , Jakubowski Jacek , Tomczak Kamil
Published: November 2017

Steel structures for a conveyance guiding system are subjected to prolonged, intense corrosion during their operation leading to a considerable loss of material and structure capacity reduction. Shaft guides are made of closed profiles welded from hot-rolled channel sections. These profiles are categorized as class 1 cross-sections according to Eurocode 3, which means that they are resistant to local instability upon bending [1]. With an increase in the corrosion loss of the guides, the inertia moment of the cross-section is reduced. The resistance of profiles to local buckling is also reduced. However, calculations for local stability in guides upon bending are not required by the local Polish regulations on the operation of conveyance in shafts [2]. The question is whether this constitutes a shortcoming and risk for safe operation. Calculations according to steel construction standards [1] supported by numerical simulation were used to evaluate shaft steelwork guides resistance to buckling and their sensitivity to corrosion loss. It was shown that the guides of corrosion loss of 52–63%, depending on profile size, are prone to local buckling.

Published: November 2017

The aim of this paper is to analyze the role of the state audit in strengthening the accountability in managing the public funds. Appropriate and effective use of public funds ensures a healthy economic and financial management, as well as transparency, which leads towards a positive development of the society as a whole. We evaluated the operation of the state audit in Macedonia by analyzing the regularity audit performed on five state institutions from 2010 to 2014 and we compared the results with the state audits in two neighboring countries. Our findings suggest weaknesses in the use of public money by the institutions covered by this analysis and in the operation of the State Audit Office. The research will help in increasing the public awareness about the necessity of responsible management in the public sector.

2max) performances according to different training program intervention design with 8-week duration in prepubescent children through a multiple linear regression models. Two hundred forty-five healthy prepubescent children (aged 10.9 ± 0.5 years) were randomly assigned to a specific training program (strength training only—S; aerobic training only—A; intrasession aerobic and strength training—AS; intrasession strength and aerobic training—SA; or concurrent training performed in different sessions—CT) or a control group (no training regimen—C). It was possible to develop indirect predictive models for each training method, by including each variable pretraining, body fat percentage and body mass index. The models provided explained 82% of variance in the V̇o
2max, 98% in the 1 kg ball-throw, 96% in the 3 kg ball-throw, 92% in the countermovement jump, 93% in the standing long jump and 98% in the 20 m sprint performances. This novel approach to training evaluation and control aims to provide a tool to allow professionals to calculate changes with a high confidence level (CI 95%), to control gains and to choose the best training methodology to apply according to the defined purposes. The results of this study could be a great support to teachers, coaches, and professionals providing important tools to improve the efficacy and individualization of training.

Gibson, C, Hindle, C, McLay-Cooke, R, Slater, J, Brown, R, Smith, B, Baker, D, Healey, P, and Black, K. Body image among elite rugby union players. J Strength Cond Res 33(8): 2217–2222, 2019—There is limited information on the risk of eating disorders (EDs) and body image of elite male athletes. However, research studies suggest that there are some athletes who have poor body image and they may be at increased risk of developing EDs. Therefore, the current study investigated risk of EDs, body image, and the relationship with age, in elite rugby union players during their preseason training period. This cross-sectional study was undertaken at the start of the preseason among elite rugby union players in New Zealand. Twenty-six professional rugby union players completed a 49-item questionnaire on body image and disordered eating. A “body image score” was calculated from questionnaire subscales including “drive for thinness,” “bulimia,” and “body dissatisfaction,” with total scores above 20 indicative of poor body image. Body image scores varied from 8 to 39 out of a possible 0–100. Disordered eating behaviors were reported, including binge eating at least once a week (15%, n = 4/26), pathogenic weight control use (4%, n = 1/26), and avoidance of certain foods (77%, n = 20/26). There was a statistically significant inverse association between the bulimia subscale and age (p = 0.034). At the start of the preseason training period, many elite rugby union players experience disturbances in body image. The prevalence of disordered eating behaviors is of concern, and needs to be minimized due to the negative impact on health and performance. A focus on assessment and education of younger male rugby players may be required to reduce disordered eating patterns.

Toselli, S and Campa, F. Anthropometry and functional movement patterns in elite male volleyball players of different competitive levels. J Strength Cond Res 32(9): 2601–2611, 2018—The aim of this study was to establish specific profiles for anthropometry and functional movement parameters and identify which characteristics can be modified by training to achieve a better quality of movement in elite male volleyball players competing at the Italian National League (Super Lega = 39, aged 25.6 ± 4.7 years and A2 = 30, aged 26.2 ± 5.3 years). Another aim was to value functional movement patterns in relation to morphological traits, with special focus on differences by division and playing positions. Statistical significance was set at p ≤ 0.05. According to discriminant analysis, the differences between players of the 2 Divisions were primarily due to nonmodifiable parameters (humerus width, height, and bicrestiliac width) and modifiable parameters (contracted arm circumference and muscle area of upper arm). Our results highlighted differences according to playing positions. Middle hitters and opposites were taller, heavier and generally showed wide dimensions in contracted arm circumference, upper limb length widths, and handgrip strength than the players of the other roles. Percentage of fat mass was low in players of all roles, such as endomorph somatotype component. Ectomorphic component was maximal in middle hitters, whereas mesomorphic component was maximal in liberos. The players of the 2 Divisions did not show differences in the movement patterns, even if approximately 33% of them showed a dysfunctional movement, with a prevalence of asymmetric movements in the shoulder mobility test. Multiple regression showed that, in volleyball players, an optimal flexibility and mobility was closely related to anthropometric characters with particular emphasis on body fat.

Published: November 2017

This article presented the detailed energy and exergy analysis performed on 4 different configurations of solar photovoltaic thermal collectors under Chennai climatic conditions. A comparative performance study of all the four different configurations was performed considering two mass flow rates of air as 0.00847 and 0.01130 kg/s. The parameters such as PV temperature, inlet and outlet air flow temperatures in the cooling channels, solar radiation, and ambient temperature were analyzed and studied in detail. It was found that the collector performance enhanced with increase in air velocity with further increase in heat transfer coefficient between the absorber surface and air. The experimental results obtained from the present work and the experimental performances of previously published results are found to be in good agreement. The electrical efficiency was from 9.8 to 12.9 % for 0.00847 kg/s and from 10.3 to 13.9 % for mass flow rate of air 0.0113 kg/s. The maximum thermal efficiency lies between 4.3 and 12.4 % for the mass flow rate of air 0.00847 kg/s and from 6.5 to 15.9 % for mass flow rate of air 0.01130 kg/s, respectively. Similarly, the maximum exergy efficiency ranges from 11.2 to 38.6 % for mass flow rate of air 0.00847 kg/s, and it varies between 18.4 and 49.4 % for mass flow rate of air 0.01130 kg/s.
Who Is My Successor? Creating a Mentor–Protégé Selection and Evaluation Model Based on the Views of Mentors
Authors: Lin C.-T. , Chang T.-T.
Published: November 2017

The aim of this study is to understand the critical criteria that chefs employ in the process of selecting their protégés, and to create a mentor–protégé selection model. This study was conducted using qualitative and quantitative methods—in-depth interviews and a cause–effect model, and the Decision-Making, Trial, and Evaluation Laboratory (DEMATEL). The DEMATEL technique simplifies and visualizes the relationships among decision-making criteria. Participants in the qualitative approach were 36 senior chefs, and the quantitative approach was focused on 18 chefs who had an average of 25 years of tenure. This study successfully built a mentor–protégé selection model and implemented an influential network relation map (INRM) for solving the interdependence and feedback of criteria of practical problems. This study determined four core criteria and 14 sub-criteria for protégé selection; the results show that personal traits are the most important criteria and mutually affect interaction in the workplace, personal feelings of chefs, and character. The findings indicate that the evaluation results are valuable, and the results provide guidance for the chefs who wish to cultivate successors efficiently from the cause–effect criteria and further enhance their effectiveness and efficiency in the kitchen; it is a contribution to the mentor–protégé selection in the workplace.

Published: November 2017

In Drosophila, mature sperm are transferred from males to females during copulation, stored in the sperm storage organs of females, and then utilized for fertilization. Here, we report a gene named sheepish (shps) of Drosophila melanogaster that is essential for sperm storage in females. shps mutant males, although producing morphologically normal and motile sperm that are effectively transferred to females, produce very few offspring. Direct counts of sperm indicated that the primary defect was correlated to failure of shps sperm to migrate into the female sperm storage organs. Increased sperm motion parameters were seen in the control after transfer to females, whereas sperm from shps males have characteristics of the motion parameters different from the control. The few sperm that occasionally entered the female sperm storage organs showed no obvious defects in fertilization and early embryo development. The female postmating responses after copulation with shps males appeared normal, at least with respect to conformational changes of uterus, mating plug formation, and female remating rates. The shps gene encodes a protein with homology to amine oxidases, including as observed in mammals, with a transmembrane region at the C-terminal end. The shps mutation was characterized by a nonsense replacement in the third exon of CG13611, and shps was rescued by transformants of the wild-type copy of CG13611. Thus, shps may define a new class of gene responsible for sperm storage.

Istállóskő revisited: the osseous artefacts from the lower layer
Authors: Markó András
Published: November 2017

The Istállóskő cave is one of the classical Palaeolithic sites in Hungary, generally regarded as the only important Aurignacian locality in Hungary with two discrete culture bearing layers. The lower unit, characterised by the presence of split based points played a key role in several theories on the appearance of the Upper Palaeolithic in Europe, while in the upper layer some Mladeč or Olschewa type points were found.

In this paper the author reviews the antler and ivory artefacts found in the lower layer stored in the Hungarian National Museum. The reconstruction of assemblage formation was rather complicated, but the high number of fragments, the occurrence of typical macrofracture patterns and the rejuvenated implements shed light to the human behaviour. Finally a few pieces with sufficient preservation allow us to point some details to the operational chain of the osseous tool production.

All these aspects of the assemblage were determined by the topographic location of the cave, lying at a large relative height by the end of a long and deep valley, determining the nature of the human occupation of this locality. This raises the question of the comparability of the assemblages with other collections.

Published: November 2017

The following study deals with a looted metal sheet artefact probably originating from the Balkan region. Our main goal is to give a preliminary technological characterization of the object by the aid of four different analytical methods (macro- and microscopic observations, Neutron and X-ray Radiography, X-ray Fluorescence Spectroscopy). Using these different techniques together allowed us to characterize this complex metal sheet object more precisely than it would have been possible by traditional archaeological methods. According to our results, it seems that the technological characters of the artefact (e.g. the manufacturing technology, decorations, repair marks) are very similar to the metal sheet cauldrons of the Late Bronze Age and Early Iron Age.
Samian deposit (cache) from Papkeszi (Veszprém county, Hungary)
Authors: Gabler Dénes , Mráv Zsolt
Published: November 2017

A collector handed over to the Hungarian National Museum 15 items of samian ware which he had discovered on the outskirts of Papkeszi. All of the vessels were plain ware: Drag.33 cups or Drag.18/31 platters. 12 pieces bear stamps, with exception one they were all made by the workshops of Lezoux in the Antonine period. Their accordance as a set is evidenced by the graffiti naming Verus on 8 pieces.

The cache of Papkeszi and its closest paralell in space and time the one of Gorsium indicate that they were both purposely hidden deposits. Cache from the same era are also known from Noricum and Pannonia. Deposits from Gorsium and Aquincum can be related to the Marcomannic–Sarmatian attacks of AD 178–179 which among others resulted in the destruction of the earth-timber fort of Celamantia.

Based on samian and brooches the Roman settlement of Papkeszi was inhabited from the Flavian Age. Although its inhabitants might have hidden a cache of terra sigillata as a significant treasure, the Marcomannic–Sarmatian wars (AD 166–180) did not cause any considerable interruption in the occupation of the settlement.
Uncertainty in the estimation of hysteresis of soil–water characteristic curve
Authors: Zhai Qian , Rahardjo Harianto , Satyanaga Alfrendo
Published: November 2017

The soil–water characteristic curve (SWCC) contains key information on unsaturated soil properties and is reported to be hysteretic (i.e. the amount of water at a given suction during the wetting process is less than that during the drying process). In this paper, an equation for quantifying the hysteresis of SWCC due to the ‘ink bottle’ effect is derived. The derived equation shows the uncertainty in the estimated wetting SWCC. In this paper, an equation for quantifying the hysteresis of SWCC due to the ‘ink-bottle’ effect is derived. The derived equation shows the uncertainty in the estimated wetting SWCC. In addition, an equation for estimating the hysteresis of SWCC due to the entrapped air is also proposed. The uncertainty of the entrapped air volume for the compacted mixture of sand and kaolin is analysed using the statistical method. The uncertainty of the entrapped air volume is incorporated into the proposed equation for estimation of the wetting SWCC. Consequently, the equations for estimation of the wetting SWCC due to the ink bottle effect and the entrapped air are proposed and the uncertainty of the estimated wetting SWCC is also presented. The proposed equation is then verified using experimental data measured in this study and published data from literature. The uncertainty in the estimated wetting SWCC (or the hysteresis of SWCC) agrees with the data obtained from the experiments conducted in this study.

Authors: Kitchen Amanda , Benn Jeremy , Kirby Andrew , Jenkins Owen
Published: November 2017

Ciria has published River Weirs: Design, Maintenance, Modification and Removal to replace the Environment Agency's River Weirs Good Practice Guide of 2003. Although the previous guide was comprehensive, many lessons have been learned on the safety and operation of weirs since its publication. The water framework directive has also increased the emphasis on weir removal, lowering or modification to restore fish passage and natural geomorphological processes. In addition, interest in green energy has increased the use of weirs for hydropower generation. The new guide is aimed at all those with an interest in weirs and is freely available online. This briefing describes the functions of weirs and typical construction, potential impacts on safety and the environment, and what can be done to address shortfalls in performance. Finally, it highlights the need to raise awareness of the potential impacts of weirs among professionals and those responsible for weirs.

We report the results of an effort to measure the contribution of copyright-based industries to the South African economy. Following the methodology of the World Intellectual Property Organization, we identify the copyright industry’s contribution to GDP, employment, imports and exports in South Africa for the period 1970–2009. It was estimated that the sector contributed 4.1% to GDP – more than the contributions of other sectors such as agriculture and food, beverages and tobacco. Because of this quantified importance of the copyright-based industries, we recommend that relevant South African policy authorities and policymakers should monitor and publicise regularly the performance of the copyright-based industries as well as promote programmes for their development and growth.

Significance: 

Copyright-based industries have the potential to play an important role in job creation and economic growth.
Our findings suggest that policymakers should design and promote the implementation of future policies and strategies related to these sectors.

The early diagnosis of metastatic pulmonary calcification is beneficial, as some patients may develop restrictive changes in respiratory function or in some cases lethal acute respiratory distress. The aim of the study was to evaluate whether scanning with “mTc DPD might be useful in early diagnosis of pulmonary calcification in setting of chronic renal failure and hemodialysis and if presence of pulmonary calcification is associated with an abnormality in respiratory parameters. Forty-two patients with end-stage renal disease, who were treated by regular haemodialysis, were investigated. Twenty five (59.5%) out of forty two patients had increased lung uptake of 99mTc DPD at whole body scintigraphy-grade 2 group. These patients were on dialysis 149±26 months compared with 57±16 months in 17 patients with a normal lung uptake of 99mTc DPD at whole body scintigraphygrade 1 group (p<0.01). In grade 2 group 22 patients (88%) had significantly lower (p<0.01) parameters of spirometry (FEF25-75, FEF75 FEF50, FEF25) compared to predicted values while in grade 1 group the parameters were significantly lower in only six patients (35.3%). There was statistically insignificant difference between these two groups regarding parathyroid hormone level (p>0.05). These observations confirm previous findings that scintigraphy with 99mTc DPD may be efficious in early diagnosis of pulmonary calcification in hemodialised patients as well as the fact that spirometry is useful in patients with confirmed pulmonary calcifications.

El traslado del coro de la iglesia de San Julián y Santa Basilisa de Samos
Authors: López Salas Estefanía
Published: November 2017

En julio de 1967 tenía lugar el desmantelamiento y traslado del coro del templo del monasterio de San Julián de Samos (Lugo-España) de su posición original, en el primer y segundo tramos de la nave central, a la cabecera, provocando un cambio significativo en su organización espacial interior y en su arquitectura que perdura hoy en día. Entender las razones que justificaron esta actuación, conocer la imagen del espacio original perdido y analizar los proyectos diseñados para afrontar la reforma y sus consecuencias son los tres objetivos del trabajo que aquí presentamos.

Resumo: ao final de 1950 e na década de 1960, surgiram as primeiras discussões para a formação de um mercado de hortigranjeiro devido a existência de atividade fragmentada e informal que vinha causando problemas urbanísticos no Brasil. Objetivou-se contextualizar a criação da Central de Abastecimento de Goiás, inaugurada em 1975, seu papel e diretrizes para implantação dos espaços físicos. Realizou-se pesquisa descritiva em manuais operacionais das CEASAS do Brasil; documentos internos da CEASA-GO, artigos da época do Sistema Nacional de Centrais de Abastecimento (SINAC) pelo Ministério da Agricultura, Pecuária e Abastecimento em conjunto com a Companhia Nacional de Abastecimento (CONAB) e a Superintendência de Programas Institucionais e Sociais de Abastecimento (SUPAD) entre os anos de 1976 a 2008. Os resultados demonstram que a CEASA-GO tem um papel fundamental no comércio atacadista de hortigranjeiros, não só no Estado de Goiás, mas em todo Cerrado Brasileiro.Palavras-chave: Ceasa.

Carbon nanotubes are widely employed as catalyst supports and electrode materials. In our earlier studies, capacitance characteristics of carbon nanotubes (CNTs) and nitrogen-doped carbon nanotubes (N-CNTs) were measured. Voltammetric curves obtained for nitrogen-doped nanotubes in an acid electrolyte showed pseudocapacitance peaks that were caused by electrochemical processes involving nitrogen-containing functional groups. In this study, measurements were made in a two-electrode cell of a supercapacitor with a hydrophilic polypropylene PORP-A1 film serving as a separator in alkaline (6 M KOH solution) and acid (1 M H2SO4 solution) electrolytes using a PARSTAT 4000 potentiostat/galvanostat. A technique was developed to estimate the contribution of electrical double layer (EDL) by subtracting pseudocapacitance from total capacitance of a cell using the Origin 9 software. The contribution of EDL and pseudocapacitance to the capacitance of supercapacitor cells was estimated. The highest capacitance of an electrode material equal to 97.2 F/g (including the EDL capacitance of 65 F/g) was reached for nanotubes doped with 8.5% of nitrogen in an acid electrolyte at a potential scanning rate of 10 mV/s.

Combustion of hydroxylammonium nitrate (95 wt.% HAN) ‒ water solution in presence of high specific surface area activated carbons is investigated in a constant-pressure bomb within the pressure range of 1‒6 MPa. The linear burning rate increased for the system of HAN admixed with activated carbons compared to those of the HAN alone. Moreover, the thermal decomposition of HAN (95 wt.%) ‒ water solution spiked with activated carbons was assessed by DTA – TG method. In the presence of activated carbons, the ability to trigger the decomposition at a lower temperature (86 °C vs 185 °C) was observed. The volatile products formed in the course of thermal decomposition of HAN, spiked with activated carbons were characterized by electron ionization mass spectrometry analysis. Primary products of HAN decomposition: m/z = 33 (NH2OH) and m/z = 63 (HNO3), which are further responsible for the formation of secondary products such as N2O, NO, HNO2, NO2, O2 etc. Significant reduction of NOx emissions during thermal decomposition of HAN (95 wt.%) ‒ water solution was observed (ca. 30%) in presence of activated carbons.

Clay minerals, especially montmorillonite, as well as bentonite minerals with a high content of montmorillonite, have the highest ability to adsorb various organic compounds. In the East Kazakhstan region, the Manyrak deposit has huge deposits of “pink” bentonite clay (BC) with 70% of montmorillonite, extensively studied back in the 70-80-s. Now it is successfully useful in the organo-polymer composition as a mineral filler of polymer composite materials (PCM) and finds the application as domestic sorbents for the group extraction of non-ferrous ions in the purification of industrial sewage and drinking water. This article presents the results of research of creating polymer-clay composite materials based on domestic bentonite clay with improved sorption characteristics. The polymeric matrix of the composites consists of acrylates ‒ polyacrylic and polymethacrylic acids (PAA and PMAA). BC-PAA and BC-PMAA gels were obtained by radical polymerization “in situ” using the intercalation method (and wi

thout it). Preliminary intercalation forms more homogeneous and interconnected composite gels. An increase in the content of the clay component and the cross-linking agent in the starting mixture results in a higher cross-linking rate and compaction of the composite gels. The behavior of the swelling of gels under the influence of temperature, pH, ionic strength indicates their polyelectrolyte character with dominant hydrogen bonds and partial hydrophobic interactions (the latter is improved in the case of BC-PMAA). The preparation of composite gels based on local BC and PAA and PMAA expands the range of composite materials and can be used as sorbents for wastewater treatment.
Bioética, educación física y deporte: crítica a las epistemes que escinden al hombre y al saber

Las Epistemes que escinden al hombre en cuerpo y alma, a los saberes, y los valores, promueven actividades de Educación Física y Deporte, que comprometen las expectativas Beneficiencia, No Maleficiencia, Autonomía y Justicia, que se sugieren en la Bioética. Revertir esta situación, favorecida por el status quo capitalista neoliberal globalizado, implica la asunción de enfoques epistemológicos de la corporalidad humana y su actividad motriz, en sus dimensiones sociales, culturales, etnico-raciales, de género, políticas, y ética. El trabajo aborda de forma crítica la concepción médico-biológica cartesiana de la Educación Física y del Deporte y las tensiones existentes entre bioética, educación física y actividad deportiva.
Peões: Lula e a Nostalgia da Classe Operária
Authors: Soler Marina Jorge
Published: November 2017

Consuelo Lins, no livro O Documentário de Eduardo Coutinho, considera Peões (Eduardo Coutinho, 2004) seu filme mais melancólico (Lins, 2004: 185). O próprio documentarista, no encarte do DVD de Peões, ao ser questionado se seu filme é melancólico, responde: “Existe ali, claramente, um tempo que terminou (...). Mas eu não tinha a intenção de fazer um filme melancólico”. Efetivamente, penso que Coutinho está correto: seu filme, ao contrário do que considera Lins, não é melancólico. Não há uma idéia de tristeza pelo tempo que terminou ou de uma falta de entusiasmo que surgiria pela lembrança do passado. Peões é, na verdade, um filme nostálgico, no sentido de que nos passa antes a sensação da saudade do tempo que terminou do que de tristeza ou desânimo em relação a este.
