Influence of Steel Plate Roughness on the Frictional Properties of Cereal Kernels
Authors: Kaliniewicz Zdzisław , Żuk Zbigniew , Krzysiak Zbigniew
Published: February 2018

The aim of this study was to determine the correlation between the external friction angle of cereal kernels and the roughness of a steel friction plate. The experiment was performed on the kernels of five principal cereals: wheat, rye, barley, oats and triticale. Flat seed units composed of three spaced kernels joined by adhesive tape were analyzed in each experimental variant. The external friction angle of flat seed units was determined on 9 steel friction plates with different roughness. Measurements were performed in 3 replications with a photosensor device which registered the external friction angle of cereal kernels. On friction plates with surface roughness Ra=0.36 to Ra=6.72, the average values of the angle of external friction ranged from 17.56° in rye kernels to 34.01° in oat kernels. The greatest similarities in the angle of external friction were observed between wheat and triticale kernels, whereas the greatest differences were noted between barley and oat kernels and between barley and triticale kernels. Friction plates made of ST3S steel should be characterized by the lowest surface roughness to minimize energy consumption during grain processing. The optimal surface roughness of steel friction plates was determined at Ra=0.9.

Momordica balsamina is considered as a miracle herb used in African traditional medicine due to its tremendous medicinal and nutritional properties. In this present study we evaluated the antioxidant and antimicrobial activities of the methanol extract of Momordica balsamina (MEMB). Phytochemical screening followed by thin layer chromatography and spectrophotometrydone to measure the radical scavenging activity of 2,2-diphenyl-l-picrylhydrazyl (DPPH). Total phenolic content and total antioxidant activity of MEMB was determined. Zones of inhibition, minimum inhibitory (MIC) and minimum bactericidal concentrations (MBC) were measured by agar diffusion and liquid broth dilution assays to assess the antimicrobial activities of MEMB. Phytochemicals isolated were flavonoids, tannins, coumarins, terpenoids and phenols. The antioxidant potential and antimicrobial activity of MEMB can be attributed to the total phenolic content and other bioactive phytochemicals.MEMB showed antimicrobicidal activity more against Gram positive than Gram negative organisms. S.agalactiae,S.aureus (ATCC 25923) and L.monocytogenes were more susceptible than Proteus mirabilis, E.coli, K.pneumoniae, P.aeruginosa or S. typhimurium. MEMB also showed antifungal activity against C.albicans species though at a higher concentration[MIC - 0.938mg/ml and MBC-1.875mg/ml]. MEMB can therefore be considered as a potential medication in the management of infectious diseases.

Authors: Roberts Megan C. , Murphy Taylor , Moss Jennifer L. , Wheldon Christopher W. , Psek Wayne
Published: February 2018

Objectives. To examine how combinations of state policies, rather than single policies, are related to uptake of human papillomavirus (HPV) vaccine.

Methods. Using publicly available records and the literature, we characterized policies for each US state and Washington, DC, in 2015 (n = 51), including (1) Medicaid expansion, (2) policies permitting HPV vaccination in pharmacies, (3) school-entry requirements, (4) classroom sex education mandates, and (5) parental education mandates. Using qualitative comparative analysis, we identified which existing combinations of these policies were necessary and sufficient for high HPV vaccine initiation among adolescents, with National Immunization Survey-Teen data.

Results. No single policy was necessary or sufficient for high HPV vaccine uptake; however, 1 set of policies had consistently high HPV vaccine uptake: adoption of all policies except parental education mandates (girls: consistency = 1.00, coverage = 0.07; boys: consistency = 0.99, coverage = 0.08).

Conclusions. We identified a set of polices related to high HPV vaccine uptake. Future studies should examine how these policies and others, individually and in combination, are associated with HPV vaccine uptake.

Public Health Implications. This study provides insight into what sets of policies are consistently related to high HPV vaccine uptake.
Disparities in Distribution of Particulate Matter Emission Sources by Race and Poverty Status

Published: February 2018

Objectives. To quantify nationwide disparities in the location of particulate matter (PM)-emitting facilities by the characteristics of the surrounding residential population and to illustrate various spatial scales at which to consider such disparities.

Methods. We assigned facilities emitting PM in the 2011 National Emissions Inventory to nearby block groups across the 2009 to 2013 American Community Survey population. We calculated the burden from these emissions for racial/ethnic groups and by poverty status. We quantified disparities nationally and for each state and county in the country.

Results. For PM of 2.5 micrometers in diameter or less, those in poverty had 1.35 times higher burden than did the overall population, and non-Whites had 1.28 times higher burden. Blacks, specifically, had 1.54 times higher burden than did the overall population. These patterns were relatively unaffected by sensitivity analyses, and disparities held not only nationally but within most states and counties as well.

Conclusions. Disparities in burden from PM-emitting facilities exist at multiple geographic scales. Disparities for Blacks are more pronounced than are disparities on the basis of poverty status. Strictly socioeconomic considerations may be insufficient to reduce PM burdens equitably across populations.

En la actualidad los docentes universitarios tienen el reto de enseñar a la conocida como “generación Y”, alumnos nacidos entre los años 1980 y 2000, los cuales no han conocido el mundo sin internet o teléfono móvil. Esto por supuesto implica que el acercamiento al conocimiento, y por tanto los modos de aprendizaje, son completamente diferentes a los de generaciones anteriores. Esto unido a la implementación de las nuevas titulaciones acordes con el proceso de convergencia europea y el sistema de créditos ECTS, y siguiendo los desafíos de la enseñanza contemplados en el Espacio Europeo de Educación Superior (EEES), hace inevitable la implementación de nuevas formas de comunicación entre los alumnos y los profesores en el ámbito Universitario. Aunque en este aspecto la mayoría de las Universidades cuentan ya con diferentes herramientas de e-Learning, su uso e implementación en algunas ocasiones puede resultar insuficiente. En este escenario, por el contrario, son muchas las posibilidades que ofrecen las redes sociales y su extenso uso entre el alumnado, quien accede generalmente con mucha frecuencia a sus perfiles y grupos, proporcionando una comunicación rápida, fácil y flexible. En el presente proyecto de innovación docente hemos combinado el uso de un grupo de Facebook con los recursos tradicionales en la docencia relativa a la asignatura de Inmunología, usando esta red social como herramienta de apoyo para compartir materiales e información. Todo ello buscando un nuevo ambiente de comunicación más directo entre alumnos y profesorado, sin por supuesto tener que sustituir las vías de comunicación formales como el correo electrónico y Moodle. Esto nos ha permitido evaluar su uso, participación y satisfacción entre el alumnado que ha participado en el proyecto.

La redacción de textos académicos en inglés está íntimamente relacionada con la competencia lingüística que el alumnado universitario ha de desarrollar (B1 como requisito lingüístico mínimo previo a su graduación) y que, de manera lógica, está encadenada a la mejora de su empleabilidad (tanto a niveles nacionales como internacionales), de sus competencias comunicativas en segunda lengua y, por supuesto, la posibilidad de que los resultados de su trabajo académico trasciendan fronteras. El proyecto que aquí se presenta surge como evolución de un proyecto de innovación docente anterior, aprobado e implementado en la UCO (“La tutoría piramidal como estrategia para el diseño y desarrollo del trabajo final de grado en educación”, 2015-2-6011), y cuyo resultado ha permitido identificar la necesidad que con esta propuesta pretendemos cubrir. El objetivo final de este proyecto es enseñar al alumnado universitario a redactar sus TFG en inglés, al tiempo que el profesorado también participa en los seminarios, en los que se abordan también técnicas que faciliten la corrección de estos trabajos que se redactan en una lengua no materna o principal. La metodología se basa en seminarios participativos, así como en la elaboración de recursos, en los que alumnado (tutores y tutorizados) y profesorado (tutores y tutorizados) colaborarán para la consecución final del objetivo: la redacción y corrección de TFG, principalmente en lengua inglesa. Entre estos recursos, destacamos el diseño y la elaboración de minivídeos docentes modulares con la participación del profesorado implicado en el proyecto, así como del alumnado mentor, para explicar los aspectos clave de la elaboración de un TFG.

Published: February 2018

Drought is one of the most important factors contributing to crop yield loss. To develop drought‐tolerant maize (Zea mays L.) varieties, it is important to explore the genetic mechanism and genes involved. In this study, we identified 69 quantitative trait loci (QTLs) for plant height, ear height, anthesis‐silking interval, ear weight, cob weight, 100‐kernel weight, and ear length in two F2:3 populations in both drought‐stressed and unstressed conditions. These QTLs explained 4.0 to 17.2% of phenotypic variation in a single watering condition. Approximately 52 of the 69 QTLs were identified under water‐stressed conditions. Moreover, 21 stable QTLs were validated in one or two F2:3 populations under multiple water‐stressed conditions. Remarkably, bin 4.09 (umc2287–umc2011) had two stable QTLs for ear height and anthesis‐silking interval; bin 1.07_1.08 (bnlg1025–mmc0041) identified three stable QTLs for ear, cob, and 100‐kernel weights; bin 4.08_4.09 (umc2041–umc2287) validated four stable QTLs for ear weight, cob weight, 100‐kernel weight, and ear length; and bin 9.04_9.06 (umc1120–umc2134) mapped three stable QTLs for ear weight, cob weight, and ear length that were consistent with phenotypic correlations among traits, supporting pleiotropy of QTLs and playing important roles in conferring growth and yield advantages under drought stress. Additionally, we identified 36 meta‐QTLs across 26 populations under 52 well‐watered and 38 water‐stressed conditions using a meta‐analysis, and we predicted 39 candidate genes in the corresponding meta‐QTL intervals. These results provide valuable information for further mapping quantitative traits and revealing the genetic basis of drought tolerance.
Compatibility of the State Aid Recovery Order with the General Principles of EU Law
Authors: Rzotkiewicz Marek
Published: February 2018

According to the Article 16.1 of Regulation 2015/1589 the Commission shall not require recovery of the aid if this would be contrary to a general principle of EU law. The potential existence of such a contradiction can be then of un utmost significance to a Member State and aid beneficiaries. However, notwithstanding its significance, the notion of a general principle of EU law has not been defined in the EU legislation, has been derived from the case law of the Court of Justice. The current paper strives to analyze different sorts of general principles of the EU law and their impact on the recovery obligation, especially as such an obligation differs between particular principles. Some of those principles have no significance at all on the existence of the recovery order, while others can, and sometimes even should, bar the Commission from ordering a Member State to recover an aid.
Let us be judged by our actions. Oversight Mechanisms of Policing in Comparative Outline
Authors: Wentkowska Aleksandra
Published: February 2018

The oversight of police conduct is a fundamental governance issue and relates to concerns about democratisation and the building of a civil society. The subject of this paper is to outline the general mechanism of the oversight of police. The establishment of oversight institutions over the police is undoubtedly a key element in democratic policing. Another aim is to explain the development of the idea of resident oversight of the police, which offers some organizational examples that have been developed in some countries around the world. Examples from the UK, India and the USA revealed that oversight mechanisms vary from one country to another in terms of establishment and sustainability. The paper submits the reasons for the independent investigation of police complaints and for restoring confidence in the complaints system and in policing.

Some years ago at the MIDK2013 Conference [16] we presented a concept regarding the use of a new generation of computer programming novice languages (in fact, an environment, called ‘block languages’). We showed how we imagine the use of this kind of language for different ages and at different levels of education. Now we would like to present the results of our projects related to this concept and our psychological and pedagogical experiences. Furthermore we would like to present further tools to develop end-user programming skills from primary school to higher education.
Use and effects of patient online access to medical records in general practice through a personal health record in the Netherlands. A protocol for a mixed methods study. (Preprint)
Authors: Vreugdenhil Maria Margaretha Tjitske , Kool Rudolf Bertijn , van Boven C , Assendelft WJJ , Kremer J.A.M
Published: February 2018

BACKGROUND

In the Dutch healthcare system general practitioners have a central position and include in their electronic health records information from all healthcare providers who are involved with their patients. Online access to the summary record in general practice through a personal health record may increase patients’ insight into their conditions and help them to be involved in their care.

OBJECTIVE

We describe the protocol that we will use to investigate utilisation and effects on patient involvement experienced by patients and general practice staff of patient online access to the summary of their medical record in general practice through a personal health record.

METHODS

A multi-level mixed methods study in which the personal health record and online access to the summary record will be offered for six months to a random sample of 500 polypharmacy patients, 500 parents of under-fours and 500 adults who do not belong to the former two groups. At patient level a controlled before- and-after study will be conducted using surveys and concurrently qualitative data will be collected from focus groups, think-aloud observations and semi-structured interviews. At general practice staff level focus groups will be conducted at baseline and Q-methodology inquiry at the end of the study period.
Main outcomes at patient level are barriers and facilitators for using the personal health record and summary record and changes in taking an active role in decision-making and management of care and medication adherence. Outcomes at general practice staff level are attitudes before and opinions after implementation of the intervention. Comparisons of patient characteristics and changes in outcomes related to patient involvement over the study period will be made between users and non-users of the intervention using chi-square tests and t-tests. Thematic content analysis of qualitative data will be done and the results will be used to interpret quantitative findings.

RESULTS

Results are expected to be published in 2019.

CONCLUSIONS

We expect that the findings of this study will be useful healthcare providers and healthcare organizations that consider introducing personal health records and online access to records or recently have done so.

European Railroad Deregulation. Does it work?
Authors: Gallardo Luis Macias , Izquierdo Gregorio Escalera
Published: February 2018

We analyzed the performance of the European railway public system over the period 2004 to 2014 in which the sector was subject to a substantial restructuring process and implementation of numerous deregulation and liberalization measures with the aim to revitalize the railway. This paper estimates simultaneously a model of stochastic production frontier and a model of technical inefficiency for 16 countries. The results show technological progress and improve on technical efficiency, but it is also noted the important cuts in inputs. The network heterogeneity shows that railroad systems with down network density and high percentage of electrified network are more efficiency. Likewise, we have analyzed the impact of subsidies and reforms implemented on railways efficiency. Maintenance subsidies improve efficiency due to reductions of incidents on the rail network, let more efficient and reliable service. While, operating subsidies have a negative effect because improve inefficient behavior. By the other hand, reforms have not had the expected results. We find that vertical separation is not necessary to achieve efficiency gains. The opening passenger market seems to lead to a greater efficiency gain, but freight market shows negative results although this result can be influenced by unfavorable economic context.
DUGDALE-MAUGIS ADHESIVE NORMAL CONTACT OF AXISYMMETRIC POWER-LAW GRADED ELASTIC BODIES
Authors: Willert Emanuel
Published: February 2018

A closed-form general analytic solution is presented for the adhesive normal contact of convex axisymmetric power-law graded elastic bodies using a Dugdale-Maugis model for the adhesive stress. The case of spherical contacting bodies is studied in detail. The known JKR- and DMT-limits can be derived from the general solution, whereas the transition between both can be captured introducing a generalized Tabor parameter depending on the material grading. The influence of the Tabor parameter and the material grading is studied.
ADHESIVE WEAR: GENERALIZED RABINOWICZ’ CRITERIA
Authors: Popov Valentin L.
Published: February 2018

In a recent paper in Nature Communications, Aghababaei, Warner and Molinari [5] used quasi-molecular simulations to confirm the criterion for formation of debris, proposed in 1958 by Rabinowicz [4]. The work of Aghababaei, Warner and Molinari improves our understanding of adhesive wear but at the same time puts many new questions. The present paper is devoted to the discussion of possible generalizations of the Rabinowicz-Molinari criterion and its application to a variety of systems differing by the interactions in the interface and by the material properties (elastic and elastoplastic) and structure (homogeneous and layered systems). A generalization of the Rabinowicz-Molinari criterion for systems with arbitrary complex contact configuration is suggested which does not use the notion of "asperity".
FRACTURE MECHANICS SIMPLE CALCULATIONS TO EXPLAIN SMALL REDUCTION OF THE REAL CONTACT AREA UNDER SHEAR
Authors: Ciavarella Michele
Published: February 2018

In a very recent paper, Sahli and coauthors [12] (R. Sahli et al., 2018, “Evolution of real contact area under shear”, PNAS, 115(3), pp. 471-476) studied the contact area evolution for macroscopic smooth spheres under shear load in presence of adhesion. It was found that contact area AA reduces quadratically with respect to shear load T, i.e. A=A0-alphaAT2, where A0 is the contact area with no shearing, and alphaA is the "area reduction parameter" found to be approximately proportional to A0-3/2 across 4 orders of magnitude of A0. In this note we focus on the smooth sphere/plane contact because we believe that the case of a rough contact requires separate investigations, and we use a known model of fracture mechanics, which contains a fitting parameter b which governs the interplay between fractures modes, in order to find very good agreement between the data and the analytical predictions, developing relatively simple equations. The interaction with modes is limited.
THE “SPORT” OF ROUGH CONTACTS AND THE FRACTAL PARADOX IN WEAR LAWS
Authors: Ciavarella Michele , Papangelo Antonio
Published: February 2018

In a recent paper in Science, namely, “The Contact Sport of Rough Surfaces”, Carpick summarizes recent efforts in a “contact challenge” to predict in detail an elastic contact between the mathematically defined fractal rough surfaces under (very little) adhesion. He also suggests the next steps that are needed to “fulfill da Vinci’s dream of understanding what causes friction”. However, this is disappointing as friction has been studied since the times of Leonardo and in 500 years, no predictive model has emerged, nor any significant improvement from rough contact models. Similarly, a very large effort we have spent on the “sport” of studying rough surfaces has not made us any closer to being able to predict the coefficient of proportionality between wear loss and friction dissipation which was already observed by Reye in 1860. Recent nice simulations by Aghababaei, Warner and Molinari have confirmed the criterion for the formation of debris of a single particle, proposed in 1958 by Rabinowicz, as well as Reye’s assumption for the proportionality with frictional loss, which is very close to Archard anyway. More recent investigations under variable loads suggest that Reye’s assumption is probably much more general than Archard’s law. The attempts to obtain exact coefficients with rough surfaces models are very far from predictive, essentially because for fractals most authors fail to recognize that resolution-dependence of the contact area makes the models very ill-defined. We also suggest that in the models of wear, rough contacts should be considered “plastic” and “adhesive” and introduce a new length scale in the problem.
Quantum Horn's lemma, finite heat baths, and the third law of thermodynamics
Authors: Scharlau Jakob , Mueller Markus P.
Published: February 2018

Interactions of quantum systems with their environment play a crucial role in resource-theoretic approaches to thermodynamics in the microscopic regime. Here, we analyze the possible state transitions in the presence of "small" heat baths of bounded dimension and energy. We show that for operations on quantum systems with fully degenerate Hamiltonian (noisy operations), all possible state transitions can be realized exactly with a bath that is of the same size as the system or smaller, which proves a quantum version of Horn's lemma as conjectured by Bengtsson and Zyczkowski. On the other hand, if the system's Hamiltonian is not fully degenerate (thermal operations), we show that some possible transitions can only be performed with a heat bath that is unbounded in size and energy, which is an instance of the third law of thermodynamics. In both cases, we prove that quantum operations yield an advantage over classical ones for any given finite heat bath, by allowing a larger and more physically realistic set of state transitions.

A critical reflection on eportfolio as a teaching tool
Authors: Lewis Lyn
Published: February 2018

Eportfolios are used in early childhood, primary, secondary and higher education settings in New Zealand. While it is common practice to use the tool functions for the storage and presentation of learning, the use of eportfolio as a pedagogy is less well established. This article focuses on the author’s use of the Mahara eportfolio with primary students in an initial teacher education programme. Four critical reflective lenses are used to explore eportfolio in three learning activities: developing metacognitive skills through standards-based activities; journalling for attitudinal awareness; and expressing learning through visual narrative in an eposter. An argument is made for a shift in focus from eportfolio as a tool, towards its pedagogical capabilities. While the context of practice is higher education, the eportfolio pedagogies can be transferred to early childhood, primary or secondary contexts.
A Māori crisis in science education
Authors: Stewart Georgina Marjorie
Published: February 2018

This article is written for teachers in Aotearoa New Zealand schools who teach science to Year 7-10 students or as part of a primary classroom programme under NZC (the New Zealand Curriculum). What can teachers do about inequity in science education for Māori students? Clear understanding of this complex issue is required, so this article offers a synopsis of the Māori science curriculum debate. Written from my perspective as an insider-researcher interested in this topic for many years, this article engages with important comments about Māori-medium science education made by Sir Peter Gluckman in a major report on science education (2011), and an earlier challenge by Graham Hingangaroa Smith (1995) about the ‘Māori crisis’ in science education. The article lists and discusses options for teachers, including the potential of ‘bilingual science’ both as a useful practical approach for any classroom teacher, and as a way of navigating the current theoretical impasse or ‘crisis’ in Māori science education.
Makerspace in Education - Disruptive Technology or Just Another Passing Fad?
Authors: Gilbert Jane
Published: February 2018

Makerspaces are now common in schools. This idea, which originated outside education, is being advocated as a way to improve student engagement in learning and/or to foster creativity and/or innovation. It is also linked with “future-focused” education and is seen by some as a potentially disruptive force for good in education. This paper evaluates these claims. It looks at the origins of the makerspace concept and at how and why it was taken up by educationists. Via an exploration of the ideas about knowledge, learning and education assumed by its proponents, it assesses makerspace’s general educative potential and its likely contribution to the development of future-focused education. It concludes that the makerspace idea could be usefully disruptive in terms of education’s future development, but that this is unlikely without system-wide cognitive change.
Informal, Non-formal, and Formal Networking: Ensuring Autonomy and Flexibility for Special Needs Coordinators
Authors: Kearney Alison Claire
Published: February 2018

The importance of the Special Needs Coordinator (SENCO) in facilitating inclusive and equitable education is well supported in the literature with many countries formalising the role through legislation and policy. New Zealand however, while adopting the role of SENCO, has not formalised this role, meaning that those in SENCO positions in New Zealand experience high levels of flexibility and autonomy. This paper reports on a study of New Zealand SENCO, highlighting their day-to-day workings. A model of networked SENCO expertise is presented that reinforces SENCO autonomy and flexibility while also facilitating their needs for collaboration, sharing of practice and ongoing professional learning.
ENGINEERING METHODS FOR PREDICTING THE RESIDUAL RESOURCE OF THE EQUIPMENT
Authors: Ravin Alexander Aleksandrovich , Khrutsky Oleg Valentinovich
Published: February 2018

One of the most important indicators of reliability of technical objects is their durability. Probabilistic and statistical methods used for group assessment of service life of marine equipment at the stage of its design are unsuitable for individual assessment of a residual resource during operation due to the great values of coefficients of the resource variation and significant discrepancies between the proposed and actual operation models. Improving the reliability of estimates can be achieved by controlling the actual operation and monitoring of diagnostic parameters which characterize degradation of the actual technical state of equipment. The article considers on specific examples the features of predictive extrapolation of time-series observations over diagnostic parameter and application of forecasting method based on the actual history of operational loadings. It is stated that the extrapolation method, in spite of such advantages as using a minimum number of controlled parameters and versatility, has a number of shortcomings that reduce its effectiveness in the evaluation of residual resource of multi-mode objects. To extend the use of extrapolative forecasting there have been proposed special methods of adjusting time series using the Euler method, linear and nonlinear regression models and the estimation approach of residual resource, which provides a preliminary study of physico-chemical deterioration of technical condition of equipment and subsequent measurement of the equivalent hours of the resource using results of the check operation and the hypotheses of linear summation of damage.
PARALLEL OPERATION OF DIESEL GENERATOR SETS OF CONSTANT AND VARIABLE SPEED
Authors: Kobyakov Dmitry Sergeevich , Burda Evgeniy Mordcovich , Daryenkov Andrey Borisovich , Tarpanov Ilya Aleksandrovich , Khvatov Oleg Stanislavovich
Published: February 2018

The paper focuses on the operation of the ship's single power station with a common link of direct current and a diesel generator of variable speed are considered. It is shown that the operation of a diesel generator set at a constant (nominal) rotational speed, but variable load is characterized by a nonoptimal (overrated) specific fuel consumption. At the same time, forced regulation of the internal combustion engine rotation speed in accordance with the electric load of the generator make it possible to provide energy-efficient mode of generating electricity. One way to improve the energy performance of the ship single power station is to convert one of the parallel operating diesel generators into a variable speed mode. In this case, the load between the parallel operating diesel generators is distributed in proportion to their rotation frequencies, regardless of the individual loading of the propulsion motors. To stabilize voltage of the diesel generators operating in the variable speed mode, a power semiconductor converter is used. Functional scheme and mathematical simulation model of the ship single power station, graphs of transient processes with load changes in the channel of electric propulsion system of the vessel are presented.
The Experimenting Society

Donald Campbell wrote eloquently about the need to evaluate social reforms and lamented the lack of solid evaluation research to guide these reforms (1973).  He suggested that social reforms be thought of as experiments, and society’s focus be on important problems rather than single solutions to these problems.  Campbell’s vision of an experimenting society, in which reforms are evaluated and new approaches to social problems are developed based on evaluation outcomes has yet to be realized. DOI:10.2458/azu_jmmss_v5i2_davis
Elevated serum uric acid affects myocardial reperfusion and infarct size in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention

Aims

Elevated serum uric acid (eSUA) was associated with unfavorable outcome in patients with ST-segment elevation myocardial infarction (STEMI). However, the effect of eSUA on myocardial reperfusion injury and infarct size has been poorly investigated. Our aim was to correlate eSUA with infarct size, infarct size shrinkage, myocardial reperfusion grade and long-term mortality in STEMI patients undergoing primary percutaneous coronary intervention.

Methods

We performed a post-hoc patients-level analysis of two randomized controlled trials, testing strategies for myocardial ischemia/reperfusion injury protection. Each patient underwent acute (3–5 days) and follow-up (4–6 months) cardiac magnetic resonance. Infarct size and infarct size shrinkage were outcomes of interest. We assessed T2-weighted edema, myocardial blush grade (MBG), corrected Thrombolysis in myocardial infarction Frame Count, ST-segment resolution and long-term all-cause mortality.

Results

A total of 101 (86.1% anterior) STEMI patients were included; eSUA was found in 16 (15.8%) patients. Infarct size was larger in eSUA compared with non-eSUA patients (42.3 ± 22 vs. 29.1 ± 15 ml, P = 0.008). After adjusting for covariates, infarct size was 10.3 ml (95% confidence interval 1.2–19.3 ml, P = 0.001) larger in eSUA. Among patients with anterior myocardial infarction the difference in delayed enhancement between groups was maintained (respectively, 42.3 ± 22.4 vs. 29.9 ± 15.4 ml, P = 0.015). Infarct size shrinkage was similar between the groups. Compared with non-eSUA, eSUA patients had larger T2-weighted edema (53.8 vs. 41.2 ml, P = 0.031) and less favorable MBG (MBG < 2: 44.4 vs. 13.6%, P = 0.045). Corrected Thrombolysis in myocardial infarction Frame Count and ST-segment resolution did not significantly differ between the groups. At a median follow-up of 7.3 years, all-cause mortality was higher in the eSUA group (18.8 vs. 2.4%, P = 0.028).

Published: February 2018

Melihat dan menikmati sebuah film pada hakekatnya sama dengan membaca suatu teks dan konteks, yang di dalamnya mengandung suatu makna yang disampaikan melalui simbol atau metafora yang digunakan oleh sang kreator dan tertampil dalam jalinan cerita film tersebut. Demikian pula yang berusaha diungkapkan dalam film serial animasi Vatalla, dimana di dalamnya disematkan simbol-simbol mengenai isu nasionalisme, persatuan dan kesatuan bangsa yang dewasa ini sedang menghadapi beragam tantangan. Usaha tersebut terlihat secara jelas dari pembuatan desain karakter lima tokoh utama film serial animasi Vatalla yang mengadopsi unsur- unsur visual yang ada pada beragam motif etnik daerah di Indonesia. Desain karakter tokoh utama tersebut tampil dengan keragaman motif etnik yang disematkan pada pakaian dan asesoris yang mereka gunakan. Selain itu, kelima tokoh utama tersebut dirancang mempunyai ciri-ciri fisik yang cukup kontras berlainan satu sama lain untuk menunjukkan perbedaan suku dan ras di antara mereka (representasi dari beragam suku dan ras yang hidup di wilayah Negara Kesatuan Republik Indonesia). Dengan demikian desain karakter tokoh utama film serial animasi Vatalla ini memang diarahkan untuk selaras dengan konsep kebhinnekaan, dimana bangsa Indonesia - semenjak kemerdekaannya dan sampai saat ini di usianya yang ke-71 tahun - telah final merumuskan konsep mengenai nasionalisme tersebut dalam semboyan dasar negara Pancasila, yaitu Bhinneka Tunggal Ika.

La teoría de la disciplina formal y la lógica mental (En)
Authors: López-Astorga Miguel
Published: February 2018

La teoría de la disciplina formal sostiene que el estudio de las matemáticas desarrolla las habilidades lógicas de los individuos. Attridge e Inglis realizaron un experimento con el fin de comprobar si esta teoría es correcta o no. Su conclusión fue que sus resultados mostraban que, si bien las matemáticas pueden, efectivamente, mejorar las capacidades lógicas, es necesario asumir la interpretación defectuosa del condicional. Sin embargo, López-Astorga contraargumentó que eran posibles otras interpretaciones de sus resultados, que tales resultados no prueban que la interpretación material del condicional no es válida y que la teoría de los modelos mentales también los puede explicar. En este trabajo, comento los problemas vinculados a las otras interpretaciones posibles propuestas por López-Astorga y trato de mostrar que la mejor opción para la interpretación de los resultados de Attridge e Inglis es asumir la teoría de la lógica mental.
Modelos y representación en el estructuralismo empirista de Bas vanFraassen
Authors: Borge Bruno
Published: February 2018

El problema de cómo un modelo teórico —i.e., una entidad matemática—puede representar algo en la naturaleza es central para el EstructuralismoEmpirista (EE) de van Fraassen. Su solución consiste en identificar unelemento indexical presente en toda aserción de la forma “X representa aY”. El presente trabajo pretende mostrar que: (a) dicho problema no es unobstáculo para el realismo más de lo que lo es para el EE; (b) la soluciónde van Fraassen deja al defensor del EE ante un dilema fatal: o bien nopuede dar cuenta de algunos de los supuestos más básicos de su posición,o bien debe conceder demasiado al realismo.
La crítica marxiana de la dialéctica hegeliana. De la reproducción ideal de un proceso ideal a la reproducción ideal de un proceso real.
Authors: Caligaris Gastón , Starosta Guido
Published: February 2018

El presente trabajo examina la conexión entre el método dialéctico utilizadopor Hegel y el utilizado por Marx a la luz de los debates marxistas recientes.Se sostiene que ni el contenido ni la forma del método utilizado por Hegelpueden ser apropiados acríticamente para el desarrollo de la críticamarxiana de la economía política. Más específicamente, se sostiene queen la obra de Hegel puede encontrarse un ‘núcleo racional’ dado por eldescubrimiento de la forma más simple de auto-movimiento que tiene lo real.Sin embargo, asimismo se sostiene que por tomarse como punto de partidauna forma del puro pensar descubierta mediante un acto de abstracciónabsoluto, dicho ‘núcleo racional’ queda expuesto bajo una ‘envolturamística’ y, por tanto, en relación de exterioridad respecto del movimientode lo concreto real.
