Facile Synthesis of Ternary Alloy of CdSe1-xSx Quantum Dots with Tunable Absorption and Emission of Visible Light
Authors: Wageh S. , Al-Ghamdi Ahmed , Jilani Asim , Iqbal Javed
Published: November 2018

The synthesis of alloyed semiconductor quantum dots has produced structures that have distinct properties in comparison with both their bulk counterparts and their parent binary semiconductor quantum dots. In this work, the quantum confined structures of a ternary alloy of CdSe1−xSx were synthesized by one-pot synthesis method in an aqueous medium at a low temperature and capped with 3-mercaptopropoionic acid. Structures of the synthesized quantum dots were investigated by energy dispersive X-ray, X-ray diffraction, X-ray photoelectron spectroscopy, and high-resolution transmission electron microscopy. The obtained quantum dots had modified cubic structures as proven by X-ray diffraction and selected area electron diffraction. The optical properties of the synthesized quantum dots were characterized by optical absorption, photoluminescence, and color analysis. Optical absorption investigation revealed a widening of the band gap of CdSe1−xSx with increasing S content. This widening increased for the samples suspended in water relative to the samples measured in powder form due to the difference in the environment of the two cases. The size determined from the optical absorption measurements was found to be compatible with the sizes obtained from the X-ray diffraction with the value of bowing parameter around 1, which indicated a graded diffusion of sulfur. It was also ascertained that the emission of different compositions covered the most visible range with a small full width at half maximum. The x and y values of the chromaticity coordinates decreased with increasing sulfur content of up to 15%, while the z value increased.
Growth Condition-Oriented Defect Engineering for Changes in Au–ZnO Contact Behavior from Schottky to Ohmic and Vice Versa
Authors: Rana Abu ul Hassan Sarwar , Kim Hyun-Seok
Published: November 2018

ZnO has the built-in characteristics of both ionic and covalent compound semiconductors, which makes the metal–ZnO carrier transport mechanism quite intricate. The growth mechanism-centric change in ZnO defect density and carrier concentration also makes the contact formation and behavior unpredictable. This study investigates the uncertainty in Au–ZnO contact behavior for application-oriented research and the development on ZnO nanostructures. Herein, we explain the phenomenon for how Au–ZnO contact could be rectifying or non-rectifying. Growth method-dependent defect engineering was exploited to explain the change in Schottky barrier heights at the Au–ZnO interface, and the change in device characteristics from Schottky to Ohmic and vice versa. The ZnO nanorods were fabricated via aqueous chemical growth (ACG) and microwave-assisted growth (MAG) methods. For further investigations, one ACG sample was doped with Ga, and another was subjected to oxygen plasma treatment (OPT). The ACG and Ga-doped ACG samples showed a quasi-Ohmic and Ohmic behavior, respectively, because of a high surface and subsurface level donor defect-centric Schottky barrier pinning at the Au–ZnO interface. However, the ACG-OPT and MAG samples showed a more pronounced Schottky contact because of the presence of low defect-centric carrier concentration via MAG, and the removal of the surface accumulation layer via the OPT process.

Published: November 2018

Aluminum alloys cannot be used in aggressive corrosion environments application. In this paper, three different surface coating technologies were used to coat the 6082-T6 aluminum alloy to increase the corrosion resistance, namely Plasma Electrolytic Oxidation (PEO), Plasma Spray Ceramic (PSC) and Hard Anodizing (HA). The cross-sectional microstructure analysis revealed that HA coating was less uniform compared to other coatings. PEO coating was well adhered to the substrate despite the thinnest layer among all three coatings, while the PSC coating has an additional loose layer between the coat and the substrate. X-ray diffraction (XRD) analysis revealed crystalline alumina phases in PEO and PSC coatings while no phase was detected in HA other than an aluminum element. A series of electrochemistry experiments were used to evaluate the corrosion performances of these three types of coatings. Generally, all three-coated aluminum showed better corrosion performances. PEO coating has no charge transfer under all Inductive Coupled Plasma (ICP) tests, while small amounts of Al3+ were released for both HA and PSC coatings at 80 °C. The PEO coating showed the lowest corrosion current density followed by HA and then PSC coatings. The impedance resistance decreased as the immersion time increased, which indicated that this is due to the degradation and deterioration of the protective coatings. The results indicate that the PEO coating can offer the most effective protection to the aluminum substrate as it has the highest enhancement factor under electrochemistry tests compared to the other two coatings.
Intensification of Reactive Distillation for TAME Synthesis Based on the Analysis of Multiple Steady-State Conditions
Authors: Yamaki Takehiro , Matsuda Keigo , Na-Ranong Duangkamol , Matsumoto Hideyuki
Published: November 2018

Our previous study reported that operation in multiple steady states contributes to an improvement in reaction conversion, making it possible to reduce the energy consumption of the reactive distillation process for tert-amyl methyl ether (TAME) synthesis. This study clarified the factors responsible for an improvement in the reaction conversion for operation in the multiple steady states of the reactive distillation column used in TAME synthesis. The column profiles for those conditions, in which multiple steady states existed and those in which they did not exist, were compared. The vapor and liquid flow rates with the multiple steady states were larger than those when the multiple steady states did not exist. The effect of the duty of the intermediate condenser, which was introduced at the top of the reactive section, on the liquid flow rate for a reflux ratio of 1 was examined. The amount of TAME production increased from 55.2 to 72.1 kmol/h when the intermediate condenser was operated at 0 to −5 MW. Furthermore, the effect of the intermediate reboiler duty on the reaction performance was evaluated. The results revealed that the liquid and vapor flow rates influenced the reaction and separation performances, respectively.

Authors: Alvira José Ignacio , Hita Idoia , Rodríguez Elena , Arandes José M. , Castaño Pedro
Published: November 2018

Establishing a reaction network is of uttermost importance in complex catalytic processes such as fluid catalytic cracking (FCC). This step is the seed for a faithful reactor modeling and the subsequent catalyst re-design, process optimization or prediction. In this work, a dataset of 104 uncorrelated experiments, with 64 variables, was obtained in an FCC simulator using six types of feedstock (vacuum gasoil, polyethylene pyrolysis waxes, scrap tire pyrolysis oil, dissolved polyethylene and blends of the previous), 36 possible sets of conditions (varying contact time, temperature and catalyst/oil ratio) and three industrial catalysts. Principal component analysis (PCA) was applied over the dataset, showing that the main components are associated with feed composition (27.41% variance), operational conditions (19.09%) and catalyst properties (12.72%). The variables of each component were correlated with the indexes and yields of the products: conversion, octane number, aromatics, olefins (propylene) or coke, among others. Then, a data-driven reaction network was proposed for the cracking of waste feeds based on the previously obtained correlations.
Developing Adequate Communication of Waste Footprints of Products for a Circular Economy—A Stakeholder Consultation
Authors: Laurenti Rafael , Martin Michael , Stenmarck Åsa
Published: November 2018

Relatively few consumers are conscious of the waste generated in the course of producing the goods that they consume, although most are aware of the amount of waste they dispose of. This article reports on a small-scale survey (N = 28) among stakeholders aimed at developing adequate communication of preconsumer waste footprints of consumer goods in the context of the circular economy. Life cycle assessment (LCA) practitioners and consumers assessed five methodological details of an approach for calculating and communicating a product waste footprint (PWF). Most of the respondents expressed that the guidelines described in the proposed PWF methodology are good enough for the purposes of differentiating waste and byproducts, and defining which material flow shall be accounted for. Some LCA practitioners declared that the proposed streamlined method may not be adequate for conveying the environmental significance of waste types. The respondents also expressed that the PWF concept would be primarily useful and/or needed for consumers and government, and in the contexts of improving environmental awareness of consumers, environmental policy making, visualizing waste flows in a circular economy, and improving resource efficiency in industry, and less useful/needed in a business-to-business context. The PWF has been successfully used by diverse stakeholder groups in Sweden mostly to promote sustainable production and consumption across society. A notable example is the ‘invisible waste’ (#invisiblewaste) campaign of the Swedish Waste Management Association (Avfall Sverige). The concerns of the LCA experts have therefore not held true. The symbolic power and parsimony of the PWF concept appears to be effective in sensitizing consumers towards waste issues so that circular economy strategies beyond recycling are possible to be fully realized.
Motion Planning and Reactive Control Algorithms for Object Manipulation in Uncertain Conditions
Authors: Costanzo Marco , De Maria Giuseppe , Lettera Gaetano , Natale Ciro , Pirozzi Salvatore
Published: November 2018

This work proposes the application of several smart strategies for object manipulation tasks. A real-time flexible motion planning method was developed to be adapted to typical in-store logistics scenarios. The solution combines and optimizes some state-of-the-art techniques to solve object recognition and localization problems with a new hybrid pipeline. The algorithm guarantees good robustness and accuracy for object detection through depth images. A standard planner plans collision-free trajectories throughout the whole task while a proposed reactive motion control is active. Distributed proximity sensors were adopted to locally modify the planned trajectory when unexpected or misplaced obstacles intervene in the scene. To implement a robust grasping phase, a novel slipping control algorithm was used. It dynamically computes the grasp force by adapting it to the actual object physical properties so as to prevent slipping. Experimental results carried out in a typical supermarket scenario demonstrate the effectiveness of the presented methods.
Discrimination Algorithm and Procedure of Snow Depth and Sea Ice Thickness Determination Using Measurements of the Vertical Ice Temperature Profile by the Ice-Tethered Buoys
Authors: Zuo Guangyu , Dou Yinke , Lei Ruibo
Published: November 2018

Snow depth and sea ice thickness in the Polar Regions are significant indicators of climate change and have been measured over several decades by ice-tethered buoys. However, sea ice temperature profiles measured by ice-tethered buoys are rarely used to infer snow depth and sea ice thickness owing to the lack of automatic discrimination algorithms, restricting the use of the data for sea ice thermodynamics studies. In this study, snow depth and sea ice thickness were retrieved through the measurements of sea ice temperature profiles using discrimination algorithms of the change point and the maximum likelihood detection methods. The data measured by 50 ice-tethered buoys were used to evaluate the accuracy of the results determined by the algorithm. Influences on the seasonal sea ice thermodynamic state, vertical interval of temperature sensors on the buoys, and initial ice thickness on the estimation errors were also evaluated. The performance of the discrimination algorithm for the data from the Arctic and Antarctic regions was also compared. There were no identifiable differences between the estimation errors from the Arctic and Antarctica. Increases in both the interval of the temperature sensors and the initial ice thickness enlarged the error for the estimation of ice thickness. A procedure developed in this study strengthens the potential application of measurements from the ice-tethered buoys only with the measurements of the vertical temperature profile of the layer of snow-covered ice, but not the measurements of ice basal and surface positions using acoustic sounding.
Challenges in Determining the Size Distribution of Nanoparticles in Consumer Products by Asymmetric Flow Field-Flow Fractionation Coupled to Inductively Coupled Plasma-Mass Spectrometry: The Example of Al2O3, TiO2, and SiO2 Nanoparticles in Toothpaste
Authors: Correia Manuel , Uusimäki Toni , Philippe Allan , Loeschner Katrin
Published: November 2018

According to the current European regulation on cosmetics, any ingredient present as a nanomaterial should be indicated in the ingredient list. There is a need for analytical methods capable of determining the size of the relevant ingredients and thus assessing if these are nanomaterials or not. An analytical method based on asymmetric flow field-flow fractionation (AF4) and inductively coupled plasma-mass spectrometry (ICP-MS) was developed to determine the size of particles present in a commercial toothpaste. Multi-angle light scattering (MALS) was used for on-line size determination. The number-based particle size distributions (PSDs) of the particles were retrieved upon mathematical conversion of the mass-based PSDs recovered from the AF4-ICP-MS fractograms. AF4-ICP-MS allowed to separate and detect Al2O3 and TiO2 particles in the toothpaste and to retrieve a correct TiO2 number-based PSD. The potential presence of particles in the lower size range of the Al2O3 mass-based PSD had a strong impact on sizing and nanomaterial classification upon conversion. AF4 coupled with ICP-MS and MALS was found to be a powerful approach for characterization of different particles in a multiple-particle system such as toothpaste. Confirmation of particle size by a secondary method such as single particle ICP-MS or hydrodynamic chromatography was crucial.
An Analysis of the Effects of Climate Change Policy, Stakeholder Pressure, and Corporate Carbon Management on Carbon Efficiency on the Korean Petrochemical Industry
Authors: Lee Soo-Hyun , Lee Su-Yol
Published: November 2018

Climate change is a challenging issue for government and society as well as in business circles; it has the potential to transform the competitive business environment entirely. This study analyzed the carbon efficiency of petrochemical companies subject to the Target Management System, a Korean carbon policy. The results of data envelopment analysis of 20 Korean petrochemical companies over three years yield some interesting findings. First, companies showed a wide range of carbon efficiency ranging from 0.05 (the least efficient) to 1.00 (the most efficient). Second, because this gap is so wide, the effect of the TMS carbon policy was not apparent. Third, pressure from media and financial investors facilitates carbon efficiency. Fourth, firms’ efforts toward low-carbon product/technology development also improve carbon efficiency. This study provides some implications for managers and policy-makers who wish to foster firms’ competitiveness and reduce greenhouse gas emissions at the same time.

Authors: Wang Kaiyong , Zhang Pengyan , Pang Bo
Published: November 2018

The progressive development of the agricultural production system is the foundation for promoting the rapid and efficient growth of the regional economy. In this study, the irrigation benefit allocation coefficient for the agricultural irrigation system of Henan Province from 1999 to 2014 was comprehensively investigated on the basis of the theory of emergy analysis. The process and mechanism of the variation coefficient were explored using ArcGIS 10.1 (Environmental System Research Institute, Redlands, USA) and SPSS 21.0 software (IBM, Chicago, USA), and the results were shown spatially. From the analysis and results, the emergy investment and yield in the Henan agricultural production system were found to continuously increase with annual increases of 2.26% and 4.22%, respectively. However, the irrigation benefit allocation coefficient of Henan showed a continuous downward trend with a total decrease of 0.026 due to precipitation. The irrigation benefit allocation coefficient fluctuated owing to the combined influence of multiple restraining factors, among which chemical fertilizers and pesticides played the dominant role. Therefore, comprehensive application of multiple emergy investment methods was critical for boosting emergy yield.
Human Activities Recognition Based on Neuro-Fuzzy Finite State Machine
Authors: Mohmed Gadelhag , Lotfi Ahmad , Pourabdollah Amir
Published: November 2018

Human activity recognition and modelling comprise an area of research interest that has been tackled by many researchers. The application of different machine learning techniques including regression analysis, deep learning neural networks, and fuzzy rule-based models has already been investigated. In this paper, a novel method based on Fuzzy Finite State Machine (FFSM) integrated with the learning capabilities of Neural Networks (NNs) is proposed to represent human activities in an intelligent environment. The proposed approach, called Neuro-Fuzzy Finite State Machine (N-FFSM), is able to learn the parameters of a rule-based fuzzy system, which processes the numerical input/output data gathered from the sensors and/or human experts’ knowledge. Generating fuzzy rules that represent the transition between states leads to assigning a degree of transition from one state to another. Experimental results are presented to demonstrate the effectiveness of the proposed method. The model is tested and evaluated using a dataset collected from a real home environment. The results show the effectiveness of using this method for modelling the activities of daily living based on ambient sensory datasets. The performance of the proposed method is compared with the standard NNs and FFSM techniques.
Chlorotoxin—A Multimodal Imaging Platform for Targeting Glioma Tumors
Authors: Cohen Gadi , Burks Scott R. , Frank Joseph A.
Published: November 2018

Chlorotoxin (CTX) is a 36-amino-acid disulfide-containing peptide derived from the venom of the scorpion Leiurus quinquestriatus. CTX alters physiology in numerous ways. It interacts with voltage gated chloride channels, Annexin-2, and matrix metalloproteinase-2 (MMP-2). CTX-based bioconjugates have been widely subjected to phase I/II clinical trials and have shown substantial promise. Many studies have demonstrated that CTX preferentially binds to neuroectodermal tumors, such as glioblastoma, without cross-reactivity to normal brain cells. With its ability to penetrate the blood-brain-barrier (BBB) and its tyrosine residue allows covalent conjugation with functional moieties, CTX is an attractive platform to explore development of diagnostic and therapeutic agents for gliomas. In this review, we outline CTX structure and its molecular targets, summarize molecular variations of CTX developed for glioma imaging, and discuss future trends and perspectives for CTX conjugates as a theranostic agent.
International Media and Tourism Industry as the Facilitators of Socialist Legacy Heritagization in the CEE Region
Authors: Čamprag Nebojša
Published: November 2018

After the fall of state socialism in Central and Eastern Europe (CEE), the socialist legacy became a matter of contested discourses, coming from the new national governments. However, with the recently awakening nostalgia for socialism and growing international interest for the socialist pasts, the approaches to its legacies began gradually to change. In this paper, the focus is on some recent international trends with regards to the socialist heritage for evaluating the share of their influences in the process of de-contestation occurring at the local/national levels. There are two processes standing in juxtaposition to be observed; on the one hand, official nation branding distances the state from socialist pasts to emphasize, often contrasting, post-socialist national identity. On the other hand, the development of communist heritage tourism attempts to reconsider and appropriate socialist legacies in the national frameworks for identity construction. Using the examples from Hungary, Romania, and the former Yugoslavia, the author demonstrates the role of international media and the tourism industry for meeting the objectives of economic development while maintaining post-socialist national identity senses, but also their potentials in reconsiderations of the contested history chapters.

Formation temperature and chemistry of brine inclusions in euhedral quartz crystals from Permian salt in the Danish Trough
Authors: Fabricius Johs.
Published: November 2018

Classic microthermometry has been carried out on fluid inclusions in euhedral quartz from the Batum saltdome in the dome area of N.Jutland, Denmark. The salt studied is of Zechstein 1 and 2 age. The fluid inclusions are either isolated regular inclusions or populations of irregular thin inclusions on an internal crystal face. The inclusions are either fluid-gas inclusions or inclusions also containing a solid phase of NaCl.

The salinity and the CaCl2:MgCl2 ratio have been measured using phase diagrams of the system (CaCl2 + MgCl2)-NaCl-H2O, the Ca:Mg ratios 3:1, 1:1 and 1:3. The salinity determined is from c.35 weight % to more than 45 weight % and the Ca:Mg ratio from 3:1 to 1:4.

The homogenization temperatures of 231 fluid-gas inclusions give a mean Th=98.1 °C indicating a formation of the quartz crystals late in Zechstein 3. The formation temperatures (115 °C-180 °C) and pressures (15 MPa-90 MPa) have been measured/calculated on 14 quartz crystals indicating an individual crystallization in the period Early Triassic-Early Jurassic times. The calculated Rayleigh numbers indicate conditions of thermal convection in Late Triassic-Early Jurassic times. Both the Zechstein 1 salt and the Zechstein 2 salt were sedimented under uniform conditions.

Authors: Soeroso Noni Novisari , Tanjung Muhammad Faiz , Afiani Dina , Pradana Andika , Tarigan Setia Putra , Wahyuni Arlinda Sari
Published: November 2018

BACKGROUND: Serum Procalcitonin (PCT) is a biomarker that is frequently used to diagnose an infection. In some cases of thoracic malignancy, procalcitonin level appears to increase. However, the role of procalcitonin to diagnose malignancy is not certain yet, and the causes have not been known.
AIM: This study aimed to investigate procalcitonin levels in non-small cell lung cancer patients.
METHODS: This was an observational study with a cross-sectional design. All lung cancer patients did not diagnose based on cytology/histopathology results with no evidence nor were signs and symptoms of infection recruited through consecutive sampling. The subtypes of lung cancer include adenocarcinoma, squamous cell carcinoma, and large cell carcinoma, staged III and IV. The procalcitonin levels were analysed from blood using immunofluorescent assay. Data were then analysed with the Chi-Square test by Epi Info™ 7 programs in which p-value < 0.05 was considered statistically significant.
RESULTS: A total of 68 lung cancer patients fulfilled the criteria of this study, 55 men (80.9%) and 13 women (19.1%). The highest percentage of cytology/histopathology type found was adenocarcinoma (80.9%), and 60.3% of those were diagnosed in stage IV. An increased procalcitonin level (greater than 0.01 ng/mL) occurred in 80.9% of Non-Small Cell Lung Cancer (NSCLC) patients. It appears that the higher the stage of lung cancer, the lower procalcitonin levels would be, although it was not statistically significant. There was no association between lung cancer subtype with procalcitonin levels.
CONCLUSION: An increased level of procalcitonin may be an indication not only for infection but also for Non-Small Cell Lung Cancer.
Rocky Road Ahead Of Nursing Presence in the Oncology Care Unit: A Qualitative Study
Authors: Mojarad Fereshteh Araghian , Jouybari Leila , Sanagoo Akram
Published: November 2018

BACKGROUND: Cancer patients need not only well-planned treatment, but also comprehensive nursing care provided with compassion, competence, and conscience. Nursing presence is an essential part of the care process in all nursing interventions.
AIM: This study aimed to identify the barriers to the nursing presence in oncology care units.
MATERIALS AND METHODS: A qualitative content analysis study was carried out with the participation of 27 nurses who were chosen by purposive sampling. The data collection instruments were semi-structured interviews and observation. The interviews were recorded and transcribed, and then coded and analysed by the Graneheim and Lundman’s content analysis methodology. The criteria proposed by Guba and Lincoln were used to ensure the validity of the research.
RESULTS: From the data analysis, the researchers were able to obtain a primary theme labelled “Rocky road ahead of nursing presence” and two subthemes labelled “Difficult and stressful work environment” and “Dysfunctional rules and regulations” with several subcategories including “exposure to violence”, “shortage of nursing staff”, “inattention to the needs of nurses”, “organizational unfairness”, “excessive paperwork”, and “need for detailed documentation”.
CONCLUSION: There are numerous challenges ahead of achieving satisfactory nursing presence and quality care in the oncology care units. The findings highlight the key role of organisational conditions in the nursing presence and the dire need to pay further attention to the motivational factors.
Allergic Contact Dermatitis, Angioneurotic Edema and Conjunctivitis in a Patient with Autoimmune Thrombocytopenia – A Clinical Case
Authors: Dermendzhiev Svetlan , Ivanovska Mariya Vlado , Dermendzhiev Tihomir
Published: November 2018

Allergic contact dermatitis (ACD) is common in clinical practice, but the etiology of this disease is quite varied. A leading pathogenetic mechanism is cell-mediated immunity. The combinations of ACD with other allergic and systemic autoimmune diseases are relatively rare, but these conditions are undoubtedly a professional challenge for practitioners. We present a case of ACD combined with other immune-allergic conditions. Etiology and pathogenesis in these cases are not well understood.

Authors: Andova Valentina , Georgievska-Ismail Ljubica , Srbinovska Elizabeta , Janeska Biljana
Published: November 2018

BACKGROUND: Coronary artery disease (CAD) is the leading cause of mortality and morbidity in patients with diabetes (DM).
AIM: Тhe aim of our study was to analyse the ability of pharmacological SE to risk stratify patients with DM using qualitative and quantitative assessment of LV function.
METHODS: We prospectively assessed 105 consecutive patients (58.7 ± 9.5 y, 39 male) with known or suspected CAD who underwent dipyridamole or dobutamine SE.
RESULTS: Change of systolic LV function at maximal SE was less pronounced in patients with DM, while parameters of the diastolic function and its change with stress were almost insignificant. WMSI in comparison to GLS% didn’t make a difference in SE outcome regarding DM presence. WMSI was almost unchanged at maximal stress in diabetic patients. Conversely, GLS% showed significant worsening at maximal stress in diabetic patients. However, only WMSI at maximal stress along with DM presence appeared as independent predictors of the presence of new and worsening CAD during SE. Longitudinal strain assessed using speckle tracking during pharmacological stress echocardiography was superior to conventional echocardiography expressed by wall motion analysis in making a difference regarding DM presence.
CONCLUSION: We confirmed the usefulness of stress echocardiography using qualitative and/or quantitative parameters in the detection of CAD in patients with DM.

Published: November 2018

BACKGROUND: Hyperglycemia is common in acute stroke patients. Hyperglycemia can induce the production of reactive oxygen species, causing increased activity of matrix metalloproteinase-9 (MMP-9).
AIM: This study aimed to determine an association between the increased levels of MMP-9 and the incidence of hyperglycemia in acute ischemic stroke patients.
METHODS: This is a case-control study. Acute ischemic stroke patients admitted to the Stroke Unit of a reference hospital in Yogyakarta, Indonesia was divided into the hyperglycemic and non-hyperglycemic group. Demographic and clinical characteristics of each subject were recorded, and blood levels of MMP-9 were measured. Seventy-one patients were recruited, 40 subjects in the hyperglycemic group and 31 subjects in the non-hyperglycemic group.
RESULTS: The median levels of blood MMP-9 level in the hyperglycemic and non-hyperglycemic group were 974.37 and 748.48 ng/mL, respectively, and the difference was statistically not significant (95% CI, 191.24-2849.53; p = 0.07). When the calculated cut-off point of 600.99 ng/mL was used, the proportion of patients with higher MMP-9 levels was significantly more in the hyperglycemic group compared with the ones in the non-hyperglycemic group (82.5% and 54.8%, respectively; OR = 3.88; p = 0.011).
CONCLUSION: We concluded that the proportion of patients with MMP-9 level >600.99 ng/mL was significantly higher in acute ischemic stroke patients with hyperglycemia.ng/mL was significantly higher in acute ischemic stroke patients with hyperglycemia.

Published: November 2018

BACKGROUND: Due to the prevalence of shoulder injuries among athletes and other people and the prevalence of radiography for these injuries, there are still no valid criteria for indication of doing shoulder radiography.
AIM: This study aimed to examine the relationship between some signs and clinical examinations of the shoulder with shoulder bone injuries and the need for radiography.
METHODS: This is a cross-sectional study. All patients aged 18-70 years who referred to the emergency ward of Imam Reza and Hasheminejad Hospital in the year 2014 due to blunt trauma and had criteria for entering the study and lacking exclusion criteria were included in the study process. Data on clinical symptoms, radiographic results, and final diagnosis were extracted from the patients' records through a questionnaire and analysed statistically.
RESULTS: There was a significant relationship between the clinical signs of patients Existence of ecchymosis in the shoulder fractures with glenoid and humerus fractures (p = 0.029, p = 0.004 respectively). There was also a significant relationship between clavicle fracture and limitation in shoulder rotation and abduction (p = 0.000 and p = 0.001 respectively). Other clinical symptoms did not show any significant relationship with radiographs indicative of the problem requiring specific treatment.
CONCLUSION: Although it is possible to define critters based on clinical symptoms that reduce the need for unnecessary radiographs that the does not reliably help inpatient treatment, but finding these critters to indicate the performance of the graphs in shoulder injuries requires further studies with the higher population and more clinical variables.

Filosofía política e ideología: ¿Una relación difícil o complementaria?
Authors: Freeden Michael
Published: November 2018

Este trabajo examina la relación entre los campos de la filosofía moral y política y el estudio de las ideologías. Comienza por abordar una serie de reservas que los filósofos tienen usualmente sobre el estatuto científico de la investigación sobre ideologías. Procede a continuación a destacar el estilo singular de la investigación filosófica: su continuidad sin ruptura entre el estudio de la filosofía y los argumentos que examina, que contrasta con el lenguaje profesional del estudio de las ideologías, claramente diferenciado del lenguaje de los ideólogos. El trabajo presenta a continuación una perspectiva conceptual para el estudio de las ideologías, que complementa las contribuciones de la filosofía moral y política. Finalmente defiende que la filosofía moral y política y los estudios sobre ideologías pueden compartir de un modo fructífero métodos y visiones.
Práctica del intelectual más allá del saber: Lyotard, Foucault, Blanchot
Authors: Quintana Domínguez Idoia
Published: November 2018

En el presente artículo abordamos diferentes interpretaciones críticas de la figura y la labor del intelectual. Partimos del análisis de Lyotard sobre el declive de los parámetros universalistas y la consiguiente desaparición de la figura del intelectual clásico. A continuación, analizamos la descripción que realizan Foucault y Blanchot de esta figura, de la que defienden su vigencia. Estos dos autores exploran la labor del intelectual desde una perspectiva diferente a la de los discursos prescriptivos, universalistas y liberadores que durante cierto tiempo la caracterizaron. Proponiendo de este modo un notable desplazamiento en el modo de comprender el compromiso intelectual, ambos apuestan por la afirmación de unas prácticas sin anticipación teórica programática, que exigirán una exposición y alteración del sujeto, donde el saber ya no será salvaguarda, fundamento ni orientación.
Igualdad natural como la base objetiva de los juicios morales: una consideración sobre los sentimientos irregulares del Espectador Imparcial
Authors: Ledesma Albornoz Álvaro
Published: November 2018

En su obra The Theory of Moral Sentiments Adam Smith bien advierte que existen ciertas ocasiones en las cuales hasta el más imparcial de los espectadores siente una ‘irregularidad del sentimiento’ al juzgar el valor moral de una acción. Un ejemplo de esta irregularidad puede hallarse en los casos donde, por influencia del azar, la consecuencia de la acción no se sigue directamente del diseño del agente (humano). En el presente artículo se abordará esta problemática para, a través de ella, fundamentar la siguiente tesis: el reconocimiento de la igualdad natural entre todos los agentes morales es el punto objetivo que debe fundar todo juicio moral. Una vez mostrado ello, una pregunta digna de abordaje surgirá: ¿Por qué el inocente, aquel que no es injusto pero es causa material del daño fáctico, siente una especie de remordimiento frente al acto y de cierta forma se siente “culpable”?
Tiempo Histórico. Una promesa de aceleración
Authors: Torres Felipe
Published: November 2018

El presente escrito es un intento por mostrar algunos rasgos característicos de la figura “tiempo histórico” y su vínculo con la idea de una aceleración de la historia desde su origen. El término tiempo histórico, utilizado como concepto fundamentalmente desde el siglo XVIII en adelante, corresponde a una manera de entender el mundo contemporáneo como el momento en que tiene lugar una cronología del tiempo y, junto a ello, la aparición de la historia. Diferentes esquemas temporales dan cuenta de este tránsito; entre ellos el paso de una sincronía a una diacronía, el cambio de la iteralidad al acontecimiento, la circularidad a la linealidad. En lo que sigue proponemos observar algunas de las implicancias y formas de articulación de un tiempo histórico y la aceleración de la sociedad en la medida que ambos se perciben como elementos interdependientes.
Acumulación originaria y capitalismo neoliberal. Una posible lectura del Chile post-golpe
Authors: Fagioli Andrea
Published: November 2018

El artículo se propone pensar el «capitalismo neoliberal» a la luz de la noción marxiana de «acumulación originaria» e intenta verificar el marco teórico construido en la historia contemporánea de Chile. La primera parte es una exploración del debate actual sobre la noción de acumulación originaria. La segunda parte caracteriza al capitalismo neoliberal como una forma de nueva acumulación originaria, de la cual podemos identificar un polo objetivo, que llamamos neoliberalismo como desposesión, y un polo subjetivo, que enmarcamos en lo que llamamos neoliberalismo como tecnología (o neoliberalismo biopolítico). En la tercera parte tomamos la historia del Chile post-Golpe, para hacer emerger la función fundadora de la violencia en el capitalismo neoliberal.
Barth on election and the Canons of Dort
Authors: Dreyer Wim A.
Published: November 2018

After the Second World War, a renewed interest in the doctrine of election became evident. Several influential and leading theologians published monographs on divine election. One reason for this was the publication of the second part of volume two of Karl Barth’s Kirchliche Dogmatik during 1942. Barth regarded the doctrine of election as the heart of the gospel. Fifty years after Barth’s death and in the year in which reformed churches all over the world commemorate the Synod of Dort (1618–1619), this contribution reflects on Barth’s revisionist understanding of election and his critique of the Canons of Dort.

Il successo di EGA presso gli studiosi italiani
Authors: Cardone Vito
Published: November 2018

Da molti anni sono convinto che EGA sia la migliore rivista di rappresentazione dell’architettura – se non addirittura di tutte quelle che si interessano di rappresentazione grafica – e non ne faccio mistero. È ovvio che non tutti condividono e qualcuno si arrabbia quando lo affermo, ma si tratta di opinione meditata, suffragata da dati inoppugnabili, svincolati dal mio personale rapporto con la rivista e i colleghi che la curano.
“El servicio tiende la ropa y canta”. Los planos de Francisco Mitjans: los personajes y las notas al margen
Authors: Alcalde Sebastián Miguel Ángel , Solaguren-Beascoa De Corral Félix
Published: November 2018

El particular grafismo que Francesc Mitjans utilizó en sus planos, sobre todo en lo que a edificación residencial se refiere, y en particular las ilustraciones y anotaciones al margen de los mismos, nos acercan a la personalidad y profesionalidad de este arquitecto, que logró ir más allá de la presión especulativa y capitalista de la arquitectura residencial de su tiempo para lograr ejemplos de obra construida de sobresaliente calidad que aún hoy alcanzan el raro privilegio de poder llamarse “casas” en lugar de “edificios de vivienda”.
Sobre lo interior y lo exterior al arte y la arquitectura: punto de partida para una teoría analítica contemporánea
Authors: Ampliato Briones Antonio Luis
Published: November 2018

Este artículo plantea la necesidad de reflexionar sobre el interior y el exterior del arte y la arquitectura como principios opuestos para la construcción de una teoría analítica de la creación artística y arquitectónica contemporánea. La producción teórica del siglo XX parece haber dudado con frecuencia entre un paradigma perceptivo y un paradigma creativo, con una delimitación a veces imprecisa entre ambos. Sólo el segundo respondería a los principios que dieron sentido a la gran revolución artística y arquitectónica contemporánea. El contenido propuesto se estructura en cuatro apartados con los que se intenta transmitir una breve síntesis de las distintas posiciones que, en torno a estos dos paradigmas, se han dado a lo largo del siglo XX.

A ausente presença do corpo
Authors: Santa Everton Vinícius de
Published: November 2018

O comportamento dos sujeitos envolvidos e imersos nos ambientes virtuais configuram novos paradigmas diante das ferramentas digitais e dos textos literários no meio virtual. Nesse sentido, é importante compreender como essa relação transforma as percepções de mundo dos sujeitos envolvidos nesse ambiente de possibilidades múltiplas chamado ciberespaço e que vem construindo uma relação sujeito-máquina. Proponho discutir aqui algumas relações entre a cultura do “eu” e sobre as relações interpessoais mediadas pelos ambientes virtuais e pelas máquinas. A ideia aqui tratada é a de que caminhamos para uma configuração de relações desterritorializadas e hipercorporais que vão além do sujeito-eu do plano físico.
"Por um feminismo que queima cuecas": um estudo semiolinguístico da crítica teatral digital
Authors: Chaves Mariana Pinter , Paiva Vanessa Maia Barbosa de , Resende Priscila Natany
Published: November 2018

Este trabalho tem o objetivo de analisar o contrato comunicacional de uma crítica teatral digital. Para tanto, partimos de postulações da Teoria Semiolinguística, principalmente das noções de sujeitos da linguagem e estratégias enunciativas presentes em Charaudeau (2001 [1984], 2005 [1983] e 2015 [1983; 1992]). O texto conta ainda com pensadores sobre a crítica teatral, tais como Garcia (2004) e Small (2015), bem como de teóricos que refletem sobre as modificações comunicacionais advindas das novas tecnologias, como Lévy (1999) e Castells (2000). Por meio da análise apreendida foi possível constatar que os sujeitos produzem atos de linguagem operando no nicho dos profissionais do teatro e da escrita crítica, do público teatral e de estudiosos ou interessados dessas duas áreas. A conclusão é de que o sujeito comunicante do corpus em estudo se apresenta como gatewatcher (BRUNS, 2003) e como uma enunciadora compreendida como uma crítica teatral ignorante (SMALL, 2015), por comunicar para todo tipo de público.
Métricas Rosianas (1929-1967)
Authors: Cúrcio Verônica Ribas
Published: November 2018

Neste artigo vamos apresentar brevemente alguns resultados oriundos de um estudo de estatística textual aplicado sobre a obra literária completa de João Guimarães Rosa, sabemos que há as epístolas de Rosa, mas essas não foram utilizadas por não possuírem caráter originalmente literário. Grosso modo, vale dizer que dois campos foram amplamente explorados: o primeiro campo retrata as características gerais e específicas do próprio vocabulário empregado por Guimarães Rosa e o segundo compara os resultados obtidos com três teses da crítica literária rosiana que retratam questões intrigantes sobre o vocabulário de Rosa e suas manifestações ao longo da vida produtiva literária do autor mineiro.

Ideias preliminares sobre as noções de controle e intencionalidade em ambientes complexos de performance
Authors: Costa Rogério Luiz Moraes
Published: November 2018

Neste artigo abordo a questão do controle e da intencionalidade em performances puramente musicais ou que envolvam outras linguagens artísticas e novas tecnologias. Parto de considerações preliminares sobre o assunto relacionando-o aos contextos em que a performance se baseia na interpretação de obras escritas e aos contextos em que a mesma ocorre através da improvisação onde o conceito de obra não é tão relevante. Em seguida relaciono os mesmos temas aos ambientes de improvisação idiomática e às práticas de improvisação livre. Com relação a este aspecto, discorro sobre a questão das memórias coletivas e individuais que condicionam os ambientes de performance, relacionando-a aos conceitos de conhecimento de base e referente. Posteriormente, defino a noção de ambiente complexo de performance como sendo aquele em que vários componentes heterogêneos (inclusive componentes digitais) interagem. Finalizo o texto discutindo de forma preliminar, estes temas através de exemplos de ambientes complexos de performance.
