Close Range Tracking of an Uncooperative Target in a Sequence of Photonic Mixer Device (PMD) Images
Authors: Klionovska Ksenia , Ventura Jacopo , Benninghoff Heike , Huber Felix
Published: January 2018

This paper presents a pose estimation routine for tracking attitude and position of an uncooperative tumbling spacecraft during close range rendezvous. The key innovation is the usage of a Photonic Mixer Device (PMD) sensor for the first time during space proximity for tracking the pose of the uncooperative target. This sensor requires lower power consumption and higher resolution if compared with existing flash Light Identification Detection and Ranging (LiDAR) sensors. In addition, the PMD sensor provides two different measurements at the same time: depth information (point cloud) and amplitude of the reflected signal, which generates a grayscale image. In this paper, a hybrid model-based navigation technique that employs both measurements is proposed. The principal pose estimation technique is the iterative closed point algorithm with reverse calibration, which relies on the depth image. The second technique is an image processing pipeline that generates a set of 2D-to-3D feature correspondences between amplitude image and spacecraft model followed by the Efficient Perspective-n-Points (EPnP) algorithm for pose estimation. In this way, we gain a redundant estimation of the target’s current state in real-time without hardware redundancy. The proposed navigation methodology is tested in the German Aerospace Center (DLR)’s European Proximity Operations Simulator. The hybrid navigation technique shows the capability to ensure robust pose estimation of an uncooperative tumbling target under severe illumination conditions. In fact, the EPnP-based technique allows to overcome the limitations of the primary technique when harsh illumination conditions arise.

Clan in Transition: Societal Changes of Villages in China from the Perspective of Water Pollution
Authors: Huang Qidong , Xu Jiajun , Wei Yongping
Published: January 2018

Societal relations in rural areas have entered into a new stage of adjustment over the past decade. However, the adjustment, which might bring about profound societal changes in countryside as well as in China as a whole, have not been paid much attention and very few studies have been conducted from the perspective of ecological resource crises. We use the case of a village as an example to show how water pollution, as one of the contributory factors, possibly affect the transition of clans and societal changes in Chinese villages. Through observation and interviews, we find that there is an apparent rise of “New Clanism” within clans, which gradually abandons the tradition of supremacy of clan interests and places family or individual interests at top priority. We also find that clan boundaries get increasingly obscure since the integrity of clans is undermined by the rise of new interest groups across clans, but the boundaries remain relatively clear due to the consistency (albeit incomplete) of clan interests. Some new clan élites and representatives of new interest groups get involved in village governance, which indicates that their goals have shifted from natural resources to social or political capital. The significance of our findings is that they provide not only a unique perspective for the interaction between society and resources, but also some new ideas for the future study of rural China at the environment-social interface.
Assessment of Soil Organic Carbon Storage in Vegetable Farms Using Different Farming Practices in the Kanto Region of Japan
Authors: Matsuura Eri , Komatsuzaki Masakazu , Hashimi Rahmatullah
Published: January 2018

Agricultural fields can store substantial amounts of atmospheric carbon in the soil. In 2011, the Environmentally Friendly Farming Direct Payment Program (EFFDPP) began as a way to promote sustainable agriculture, but the approved methods for receiving the subsidy are limited to the use of manure and cover crops. For evaluating other options for the EFFDPP, we calculated soil carbon inputs and CO2 emissions in four nature farming (NF) systems for comparisons with conventional farming (CF) and environmentally friendly farming (EF) systems. In 2015, we collected data on farm management from interviews and conducted a field experiment for NF. According to the calculations using a modified Roth C model, the ability for soil carbon sequestration predicted over the next 20 years is the highest in a no-till NF system with grass mulching. CO2 emission per ha for CF was 4.8 tCO2/ha, which was eight times higher than that for NF. However, the highest CO2 emission per kg of crop was noted in NF with no grass mulching due to very low yield. The total CO2 emission for CF was similar to that for EF. The NF systems were beneficial in reducing CO2 emission, but a combination of other approaches is required for satisfying EFFDPP criteria.
The Effects of External Relations Network on Low-Carbon Technology Innovation: Based on the Study of Knowledge Absorptive Capacity
Authors: Jiang Yuguo , Chun Weide , Yang Ye
Published: January 2018

Low-carbon technology innovations (LTI) have attracted wide attention due to their effects on reducing carbon emissions, and improving LTI behavior is a kind of beneficial measures on carbon emissions control in enterprise. The current research explores the determinants that affect LTI behavioral intention, and an integrative model of external relations network (ERN) on LTI, incorporated with knowledge absorptive capacity (KAC), is used. An effective sample of 380 staffs who worked in industrial enterprise of China was collected, which empirical results reveal the correlation between KAC and LTI, ERN and LTI, and the role of KAC. Hence, this paper discusses the implications for integrative model based on KAC and provides suggestions for improving the ability of LTI, and argues that LTI is not isolated, and it needs to be realized by the combination of ERN and KAC, thus, there should be paying more call for greater attention to ERN and KAC, rather than purely focusing on resource utilization.
Evaluating the Joint Toxicity of Two Benzophenone-Type UV Filters on the Green Alga Chlamydomonas reinhardtii with Response Surface Methodology
Authors: Mao Feijian , He Yiliang , Gin Karina
Published: January 2018

The widespread occurrence of benzophenone-type ultraviolet (UV) filter has raised the public concerns over the ecotoxicological effects of these chemicals. The present study assessed the joint toxicity of two representative benzophenones, benzophenone-1 (BP-1) and benzophenone-3 (BP-3), on the green alga Chlamydomonas reinhardtii using response surface methodologies (RSM). Specific growth rate and photosynthetic pigments were used as endpoints to evaluate the toxic effects. Generally, exposure to the combined BP-1 and BP-3 negatively affected cell growth and pigments production, with higher inhibitions at higher exposure concentrations. The simultaneous reduction in growth rate and pigments contents indicated that BP-1 and BP-3 regulated the growth of the tested alga by affecting the photosynthesis process. Results also showed that second order polynomial regression models fitted well with experimental results for all endpoints. The obtained regression models further indicated that the effects of the combination stemmed significantly from the linear concentration of BP-1 and BP-3. The overall results demonstrated that RSM could be a useful tool in ecotoxicological studies.

Removal of Hardness from Water Samples by a Carbonation Process with a Closed Pressure Reactor
Authors: Ahn Min , Chilakala Ramakrishna , Han Choon , Thenepalli Thriveni
Published: January 2018

One of the undesirable characteristics of some ground and natural water sources is hardness. Hard water can cause many problems around the world, including increased scaling on water pipes, boilers, atopic eczema and odd-tasting drinking water. Hardness in natural water is caused by dissolved minerals, mainly calcium and magnesium compounds. According to the Water Quality Association (WQA) and the United States Geological Survey (USGS), hard water is classified based on the Ca2+ and Mg2+ ion concentration in waters, as follows: 0–60 ppm as soft; 61–120 ppm as moderately hard; 121–180 ppm as hard and more than 180 ppm as very hard water. Most water utilities consider a hardness level between 50 and 150 ppm of CaCO3 as publicly acceptable. The present study investigated the effects of a carbonation process on the removal of hardness in different water samples. Currently, a wide variety of hardness removal technologies are available. Among those conventional methods, carbonation is an inexpensive process which can be used for the removal of Ca2+ and Mg2+ ions from hard water. This study measured the hardness levels of 17 different water samples using the ethylene diamine tetra acetic acid (EDTA) method. Among these, Seoul outdoor swimming pool water (140 ppm) samples showed high concentrations of Ca2+ and Mg2+ ions. The hardness of the different water samples was reduced by 40–85% by a carbonation process with a closed pressure reactor for a 5 min reaction time.

The Trojan Color Conundrum
Authors: Jewitt David
Published: January 2018

The Trojan asteroids of Jupiter and Neptune are likely to have been captured from original heliocentric orbits in the dynamically excited (“hot”) population of the Kuiper Belt. However, it has long been known that the optical color distributions of the Jovian Trojans and the hot population are not alike. This difference has been reconciled with the capture hypothesis by assuming that the Trojans were resurfaced (for example, by sublimation of near-surface volatiles) upon inward migration from the Kuiper Belt (where blackbody temperatures are ∼40 K) to Jupiter’s orbit (∼125 K). Here, we examine the optical color distribution of the Neptunian Trojans using a combination of new optical photometry and published data. We find a color distribution that is statistically indistinguishable from that of the Jovian Trojans but unlike any sub-population in the Kuiper Belt. This result is puzzling, because the Neptunian Trojans are very cold (blackbody temperature ∼50 K) and a thermal process acting to modify the surface colors at Neptune’s distance would also affect the Kuiper Belt objects beyond, where the temperatures are nearly identical. The distinctive color distributions of the Jovian and Neptunian Trojans thus present us with a conundrum: they are very similar to each other, suggesting either capture from a common source or surface modification by a common process. However, the color distributions differ from any plausible common source population, and there is no known modifying process that could operate equally at both Jupiter and Neptune.
Optical Precursors to Black Hole X-Ray Binary Outbursts: An Evolving Synchrotron Jet Spectrum in Swift J1357.2–0933

Published: January 2018

We present six years of optical monitoring of the black hole (BH) candidate X-ray binary Swift J1357.2–0933, during and since its discovery outburst in 2011. On these long timescales, the quiescent light curve is dominated by high amplitude, short-term (seconds–days) variability spanning ∼2 mag, with an increasing trend of the mean flux from 2012 to 2017 that is steeper than in any other X-ray binary found to date (0.17 mag yr−1). We detected the initial optical rise of the 2017 outburst of Swift J1357.2–0933, and we report that the outburst began between 2017 April 1 and 6. Such a steep optical flux rise preceding an outburst is expected according to disk instability models, but the high amplitude variability in quiescence is not. Previous studies have shown that the quiescent spectral, polarimetric, and rapid variability properties of Swift J1357.2–0933 are consistent with synchrotron emission from a weak compact jet. We find that a variable optical/infrared spectrum is responsible for the brightening: a steep, red spectrum before and soon after the 2011 outburst evolves to a brighter, flatter spectrum since 2013. The evolving spectrum appears to be due to the jet spectral break shifting from the infrared in 2012 to the optical in 2013, then back to the infrared by 2016–2017 while the optical remains relatively bright. Swift J1357.2–0933 is a valuable source to study BH jet physics at very low accretion rates and is possibly the only quiescent source in which the optical jet properties can be regularly monitored.

Introduction: Staphylococcus pseudintermedius is coagulase-positive species of the Staphylococcus intermedius group. It is an opportunistic pathogen that can cause infection in various parts of the body and has a zoonotic potential. Although studies on the pathogenicity and epidemiology of S. pseudintermedius are limited, it is known that this bacterium has several virulence factors, including toxins. These toxins can be classified into three main groups: pyrogenic toxins with superantigenic properties such as toxic shock syndrome toxin and staphylococcal enterotoxins, exfoliative toxins, and cytotoxins  such as hemolysins and leukocidins.

Methodology: In this study, the occurrence of eight toxin genes (sea, sec, tst, SIET, EXI, LuK F-I, Luk S-I, and hlg ƴ) was examined by PCR in 58 isolates of S. pseudintermedius from four domestic animal species.

Results: All S. pseudintermedius isolates had at least one of the eight toxin genes. The predominant toxin genes were Luk S-I (95%), Luk F-I (91%), and EXI (91%), and the least prevalent gene was hlg ƴ (5%). Significant association (p = 0.0175) was found between the occurrence patterns of genes hlg ƴ and Luk F-I.

Conclusions: The frequent occurrence of these genes in S. pseudintermedius obtained from diseased animals indicates that these toxins may play an important role in the pathogenesis of infection among domestic animals.
Smoking increases the risk of surgical site infection after hydrocelectomy in adults: a retrospective cohort study in Brazil
Authors: Da Costa Thiago Silva , De Medeiros Paulo José , Salles Mauro José Costa
Published: January 2018

Introduction: Surgical site infection (SSI) following hydrocelectomy is relatively uncommon, but it is one of the main post-operative problems. We aimed to describe the prevalence of SSI following hydrocelectomy among adult patients, and to assess predisposing risk factors for infection. Methodology: This retrospective cohort study was carried out at a university hospital and included hydrocelectomies performed between January 2007 and December 2014. Diagnosis of SSI was performed according to the Center for Diseases Control (CDC) guidelines. Multivariable logistic regression analysis was used to identify independent risk factors. Results: A total of 196 patients were included in the analysis. Overall, 30 patients were diagnosed with SSI (15.3%) and of these, 63.3% (19/30) were classified as having superficial SSI, while 36.7% (11/30) had deep SSI. The main signs and symptoms of infection were the presence of surgical wound secretion (70%) and inflammatory superficial signs such as hyperemia, edema and pain (60%). Among the 53 patients presenting chronic smoking habits, 26.4% (14⁄53) developed SSI, which was associated with a higher risk for SSI (odds ratio [OR] = 2.84, 95% confidence interval [CI] = 1.27 to 6.35, p < 0.01) in the univariate analysis. In the adjusted multivariable analysis, smoking habits were also statistically associated with SSI after hydrocelectomy (odds ratio [OR] = 2.84, 95% confidence interval [CI] = 1.30 to 6.24, p = 0.01). No pre-, intra-, or post-operative variable analyzed showed an independent association to SSI following hydrocelectomy. Conclusions: Smoking was the only independent modifiable risk factor for SSI in the multivariate analysis.
Pourquoi les émeutiers s’en prennent-ils aux services publics ?

Published: January 2018

Résumé À chaque émeute urbaine que la France connaît depuis maintenant près de quatre décennies, les symboles de l’État et les équipements collectifs semblent concentrer la colère d’une partie de la jeunesse des quartiers concernés. Cette situation suscite d’autant plus d’interrogations que des moyens significatifs ont été consacrés à la rénovation des banlieues françaises dans le cadre de la politique de la ville, en particulier depuis le début des années 2000. Cet article apporte des éléments de réponses à ce paradoxe apparent, en montrant que le besoin de participation et de reconnaissance des habitants reste peu pris en compte par les pouvoirs publics et explique largement le ressentiment d’une frange de la population.
Recherches et dispositifs transculturels dans l’œuvre de Jean Claude Rouchy
Authors: Le Roy Jaak
Published: January 2018

Jean Claude Rouchy nous a permis dans la consistance de son approche groupale de penser des cadres et dispositifs adéquats dans des contextes de recherches et de soins avec des personnes des personnes dont les origines, la langue et l’appartenance culturelle nous sont étrangères et non familières. Les concepts des groupes d’appartenances primaires et secondaires, ainsi que des incorporats culturels, développés au cours d’actions-recherches transculturelles européennes, seront présentés. Pour Rouchy et les associations qu’il a co-fondées, le groupe est le cadre privilégié pour aborder les dimensions psychiques culturelles. Pour chaque intervention ou recherche, un dispositif interculturel groupal particulier doit être mis en œuvre. Ces dispositifs permettent l’émergence et l’analyse des processus culturels qui fondent les processus d’identification des personnes et des groupes. Ils rendent aussi possible de mieux prendre en charge des patients qui ont des origines culturelles et langagières différentes et des patients avec des histoires de migration et de trauma, et en général de traiter la souffrance psychique qui est liée aux changements brusques, perte ou non-transmission des références socioculturelles.
Silence collectif et bruissement de groupe à propos de crypte et d’incorporats culturels
Authors: Lecourt Édith
Published: January 2018

Cet article propose des illustrations cliniques des concepts de crypte et d’incorporats culturels développés par Jean Claude Rouchy. Ce sont des chocs culturels avec la Chine et le Japon (incorporats culturels sonores), d’une part, les indices d’un trou de mémoire collectif masqué par une légende généalogique glorieuse, d’autre part. Des incorporats culturels sonores y sont présentés sous la forme du « tapis sonore » (à partir d’une situation de musicothérapie analytique de groupe) et de « bruissement de groupe », c’est-à-dire la façon dont un groupe habite l’espace sonore. Il est montré que ces deux notions correspondent à deux données des incorporats culturels.
Influence of annealing and optical aging on optical and structural properties of ZnO thin films obtained by SILAR method
Authors: Duman Çağlar , Güney Harun
Published: January 2018

In this study, zinc oxide (ZnO) thin films are deposited on fluorine doped tin oxide (FTO) substrates by using a successive ionic layer adsorption and reaction (SILAR) method. One of the samples is not annealed and others are annealed at 200, 400 and 600 °C, and all the samples are aged under ultraviolet (UV) light for 19 h.
These samples are used to investigate the effect of annealing and aging on the properties of ZnO. Structural properties of the ZnO thin films are examined with scanning electron microscopy (SEM) and X-ray diffraction (XRD). Photoluminescence, transmittance and absorption measurements are used to observe the optical properties of the films. In the literature, there is no study investigating the effect of aging on ZnO thin films deposited with the SILAR method, hence this study fills the gap in the literature.
Autos de fe celebrados por el tribunal del Santo Oficio en Teruel (1485-1487)
Authors: Sánchez Moya Manuel , Motis Dolader Miguel Ángel
Published: January 2018

A lo largo de los tres breves pero intensos años de trayectoria como tribunal inquisitorial (1485-87), los magistrados Juan de Çolivera y Martín Navarro convocaron trece autos de fe, implicando a unas ochenta personas, y afectando a un elevado porcentaje de la población adulta de la ciudad. La mayoría pertenece a la segunda generación de conversos, descendientes de los bautizados con motivo de la Disputa de Tortosa (1412-13). Celebrados en la Plaza Mayor o en la iglesia de Santa María, y aunque todavía no se ha consolidado un protocolo definitivo, presentan una cuidada dramaturgia, donde se combina la pedagogía del miedo, la demonización de la herejía y la estructura mental y de poder. Dadas las adversas condiciones políticas en las que se implantó, sus sentencias fueron muy severas, siendo condenados a la pena de muerte un 82% de los procesados, frente a un 39% que se registra en el tribunal de Zaragoza.
«Quando Dio deciderà di redimere Israele»: vera e falsa Redenzione nel pensiero di Isaac Orobio de Castro
Authors: Silvera Myriam
Published: January 2018

El presente artículo examina algunos aspectos, nunca antes estudiados, del pensamiento mesiánico de Isaac Orobio de Castro y destaca la profunda influencia que Maimónides, por un lado, y su polémica anticristiana, por otro, ejercen en el tratamiento de esta materia. A modo de ejemplo, se sigue la objeción del autor a la tesis de que el regreso a Jerusalén bajo Ciro y la Construcción del Segundo Santuario hubieran representado la definitiva realización de las esperanzas hebraicas de bienestar temporal, tesis que liquidaba para siempre una espera orientada hacia el futuro. Eso mismo había sostenido Jerónimo de Santa Fe en Tortosa y eso mismo sostenía todavía Philipp Van Limborch, contemporáneo interlocutor de Orobio. Respondiendo a esta “falsa” redención, Orobio precisa las características y los tiempos de la verdadera «esperança» del pueblo hebreo.

Published: January 2018

O objetivo foi conhecer a atuação dos profissionais de Estratégia Saúde da Família frente ao trabalhador rural exposto aos agrotóxicos. Foi adotado o delineamento qualitativo, descritivo. O estudo foi realizado com 15 profissionais de saúde de três Estratégias Saúde da Família. Os dados foram produzidos por meio de entrevista semiestruturada e submetidos à análise temática de conteúdo. Identificou-se que a atuação dos profissionais se restringia ao atendimento de problemas agudos dos usuários. O cuidado aos trabalhadores rurais era baseado na atenção curativista, com ênfase no alívio de sinais e sintomas de intoxicação. No âmbito preventivo, não se estabelecia fluxo de atendimento, não havendo ações planejadas e direcionadas à educação e sensibilização dos trabalhadores rurais em relação à exposição aos agrotóxicos. É possível concluir que a ruralidade não foi fator considerado no planejamento das ações nas Estratégias Saúde da Família. Para renovação da prática sugere-se a educação permanente, por meio da qual os profissionais de saúde possam se instrumentalizar teoricamente, para uma prática mais efetiva.

Authors: Barros Fernanda , Carvalho Carlos Henrique de
Published: January 2018

Este texto tem como objetivo compreender a relação entre os exames preparatórios e o título de Bacharel em Ciências e Letras conferido ao aluno do ensino secundário. A relação entre os exames, o título e o ensino secundário estiveram desde 1854 até 1910 relacionadas na legislação de forma a garantir o ingresso do estudante no ensino superior. Neste texto, denomina-se este processo de racionalização, já que o objetivo primordial do secundário, desde a sua criação, a partir do Ato Adicional de 1834, seria garantir a formação do jovem brasileiro e a sua consequente preparação para o ensino superior. A forma de organização do ensino secundário nesse período permite perceber como os exames e a titulação destinavam aos alunos do secundário a garantia de um futuro, tanto no ensino superior quanto no serviço público. Utilizando a documentação sobre os exames como escopo para análise, balizada por autores que analisam a educação brasileira, conclui-se que o ensino secundário brasileiro, tanto no Império como nas primeiras décadas da República, fora instrumento de organização de um grupo de jovens que ocupariam os cargos públicos e/ou as profissões liberais com formação bacharelesca no ensino superior.

Published: January 2018

International Maritime Organization (IMO) has revised MARPOL Annex VI to accelerate the reduction of exhaust emission. MARPOL already reduce the maximum sulfur content to 0.1% inside emission control area (ECA) since January 2015. To fulfill that requirement, the ship operator should switch the fuel to marine gas oil (MGO) before entering ECA. The change-over operation could induce several potential problems because of many differences between two fuel’s properties. The potential problems can be avoided by considering both fuel specification, fuel and sulfur concentration, as well as temperature gradient of mixed fuel using Ubbelohde diagram.
Stress Analysis of the Thin Coating of the Trapeziometacarpal Replacement
Authors: Svojanovský Tomáš , Fuis Vladimír
Published: January 2018

The paper reviews stress and deformation analysis of the thin coating. The coating covers a surface of a contact component of the trapeziometacarpal joint replacement which serves as a surgical treatment of a hand joint disease called rhizarthrosis. Motivation for this study consists mainly in the fact of occasional damage of some parts of the replacement in practice [2]. It emerged that the thin coating breaks in the location of contact which opens an effort to explore stress states of such a location depending on various input parameters. Better awareness of detailed contact conditions could lead to improvement of the replacement design and, thus, prevention from necessary reoperation.

Published: January 2018

Adsorption of anionic dyes Congo Red (CR) on HDTMA surfactant-modified zeolite A has been studied. The zeolite A, which is synthesized from coal fly ash, was modified with surfactant hexdeciltrimethylammonium bromide (HDTMA-Br) as much as 200% cation exchange capacity (CEC) of the zeolite. The effect of pH, contact time and initial concentration on the CR adsorption has been evaluated.The adsorption was carried out in a batch reactor at various pH, contact time and initial concentration on the given temperature. The amount CR adsorption varies as a function of pH, contact time and initial concentration of solution. Adsorption model of Langmuir and Freundlich from empirical data is used for this experiment. The Langmuir isotherm is more suitable for this adsorption. The experimental data fulfilled pseudo second-order kinetic models. The surfactant-modified zeolite A is more effective than zeolite A without modified on the adsorption of CR in aqueous solution.

Published: January 2018

With the building integrated photovoltaic commonly using in residential and commercial buildings, fire researches about this new renewable energy system are still insufficient. Electrical failure may bring local fever at the backside of the module. In order to investigate fire potential in this situation, bench-scale experiments based on the cone calorimeter are conducted with different external heat flux from 20 to 45kWm-2 at intervals of 5 kWm-2. This paper focuses on the thermal properties and combustion behaviors of copper–indium–gallium–diselenide (CIGS) thin-film solar module, and also discusses the gas toxicity.

Published: January 2018

Palmtop tensile and fatigue testing machines were developed in-house for small and thin specimens that were fabricated by the LIGA process. The dimensions of the specimens were selected in accordance with the international standard IEC62047-3, and were 10 micrometers in thickness, 20 micrometers in width, and 500 micrometers in parallel length. Since the loading mechanism and methods of measuring the load and displacement were specially designed, the stiffness of the specimen is quite low compared to that of the conventional large-size specimens. The mechanical properties of electroformed Ni2Pd8 and Ni4Pd6 alloys were studied with these developed testing machines and excellent values of tensile and fatigue strengths of 2.7 GPa and 1.8 GPa, respectively were obtained in the case of the Ni4Pd6 alloy.

Published: January 2018

The present research aimed to develop natural rubber (NR) hybrid composites reinforced with calcium carbonate/carbon black (CC/CB) and calcium carbonate/silica (CC/SC). The influence of CC/CB and CC/SC with various filler ratios (120/0, 90/5, 60/10, 30/15 and 0/20) on cure characteristics and mechanical properties of the vulcanizates was investigated and their reinforcing efficiency was compared. It has been found that incorporation of CB in the hybrid filler decreases the scorch time and cure time but increases crosslink density, whereas the incorporation of silica showed cure retardation. As CB or SC content increases, stiffness, tensile strength and tear strength increase, while elongation at break and compression set decrease. Scanning electron microscopy studies also reveal poor filler dispersion and poor adhesion between filler particles and matrix in the vulcanizates with increasing in CC content in a weight filler ratio which causes inferior mechanical properties. Incorporation of CB or SC content enhanced the mechanical properties of the vulcanizates, where CC/CB hybrid system exhibited higher reinforcing efficiency compared with CC/SC hybrid system.

Published: January 2018

This research mainly is focused on automation of Unified Modeling Language (UML) diagrams from the analyzed requirement text using Natural Language Processing (NLP). The looks and styles of software engineering have been completely changed in the recent times. Presently, software engineering follows the rules of Object Oriented design patterns. All phases of software engineering are deviating from the conventions and new paradigms are more popular these days. Same is the case with Software analysis process which uses Unified Modeling Language to map and model the user requirements. Analysis is the key process of building modern information system applications and base for the robust and vigorous software application’s design and development. Nowadays everybody needs a quick and reliable service. It was necessary to have some sort of quick, accurate and intelligent software for generating UML based documentations to save time and budget of both the user and system analyst
The International Day of Light - May 16th
Authors: Dorosz Dominik
Published: January 2018

During 39th session of UNESCO General Conference which held on 7 November 2017 the date May 16th was proclaimed as International Day of Light (IDL). This decision was made after the success of the International Year of Light (IYL) celebrated in 2015. It confirmed that raising awareness of the social role of photonics is crucial for further development. Based on the rich experience of IYL 2015 ("more than 13,000 activities took place in 147 countries to reach an estimated 100 million people"), the most important goals are to be followed by the IDL, including: raising social awareness, education, showing the influence of photonics on culture and art, promoting foreign cooperation and the important role of conducting basic research. As a result, it will lead to the creation of new solutions based on photonic technology, which has resulted in increased energy efficiency and improved quality of our life.
Residents' Insights and Ideas about Screen-Sharing in Primary Care Clinics
Authors: Fletcher Kathlyn , Asan Onur , Tyszka Jeanne
Published: January 2018

Background Previous studies described attending physicians' perceptions of the benefits and downsides of having the electronic health record (EHR) in the room during a clinical encounter. The perspective of residents has received little attention.

Objective The goal of this project was to solicit internal medicine residents' perception of EHR use in primary care clinic visits. In this report, we focus on residents' perception of screen-sharing.

Methods We conducted qualitative, semistructured interviews of internal medicine residents. Interviews were audiorecorded, transcribed, and anonymized. Using a deductive approach to data analysis, we coded the transcripts to identify themes of interest.

Results We included 21 residents. We identified eight themes related to screen-sharing. We identified opportunities, facilitators and barriers, and outcomes related to screen-sharing. We conceptualized the outcomes, facilitators, and barriers as falling into four categories: structural, patient based, physician based, and interactional.

Conclusion Wider dissemination and adoption of curricula designed to teach residents how to incorporate EHR into the clinical encounter is needed. In addition, our study demonstrates the need to focus this training, at least in part, on screen-sharing and management of sensitive information disclosure.
Automated Screening of Emergency Department Notes for Drug-Associated Bleeding Adverse Events Occurring in Older Adults

Published: January 2018

Objective To conduct research to show the value of text mining for automatically identifying suspected bleeding adverse drug events (ADEs) in the emergency department (ED).

Methods A corpus of ED admission notes was manually annotated for bleeding ADEs. The notes were taken for patients ≥ 65 years of age who had an ICD-9 code for bleeding, the presence of hemoglobin value ≤ 8 g/dL, or were transfused > 2 units of packed red blood cells. This training corpus was used to develop bleeding ADE algorithms using Random Forest and Classification and Regression Tree (CART). A completely separate set of notes was annotated and used to test the classification performance of the final models using the area under the ROC curve (AUROC).

Results The best performing CART resulted in an AUROC on the training set of 0.882. The model's AUROC on the test set was 0.827. At a sensitivity of 0.679, the model had a specificity of 0.908 and a positive predictive value (PPV) of 0.814. It had a relatively simple and intuitive structure consisting of 13 decision nodes and 14 leaf nodes. Decision path probabilities ranged from 0.041 to 1.0. The AUROC for the best performing Random Forest method on the training set was 0.917. On the test set, the model's AUROC was 0.859. At a sensitivity of 0.274, the model had a specificity of 0.986 and a PPV of 0.92.

Conclusion Both models accurately identify bleeding ADEs using the presence or absence of certain clinical concepts in ED admission notes for older adult patients. The CART model is particularly noteworthy because it does not require significant technical overhead to implement. Future work should seek to replicate the results on a larger test set pulled from another institution.

Extension agents across the nation will need to facilitate difficult conversations with the public if genetic modification (GM) science is used to combat citrus greening disease. This study used the innovation characteristics described by Rogers to explore if using GM science as a solution to citrus greening had diffused amongst US residents. An online survey was completed by 1,051 respondents across the US. Respondents were then classified into geographic regions. Demographic differences amongst respondents from the regions were identified; however, respondents from all regions had neutral perceptions of GM science’s compatibility, trialability, complexity, and observability. All regions aside from the West agreed there was a relative advantage to using GM science; the West neither agreed nor disagreed. The Midwest was the only region with half of respondents agreeing they would consume GM citrus. All diffusion characteristics aside from observability were predictors of GM citrus consumption, and when accounting for diffusion characteristics, the Midwest was less likely to consume GM products when compared to the Northeast. Recommendations are offered for how extension agents can develop educational programming tailored to the needs of their regions to aid consumers in making educated decisions about GM citrus in the future.
