Ricardo Piglia, autor de relatos policiais. Uma leitura comparada de Plata Quemada (1997) e Blanco Nocturno (2010)
Authors: Silva Michelly Cristina Da 
Published: November 2018

O presente artigo visa comparar dois romances de Ricardo Piglia, a saber, Plata Quemada (1997) e Blanco Nocturno (2010). As duas histórias representam as incursões novelescas do autor pelo mundo dos romances policiais. Em outra ocasião, em um ensaio crítico intitulado “Sobre el género policial”, Piglia apresentou duas divisões dentro do gênero, situando-as cronologicamente e destacando suas diferenças: o romance de “enigma” ou analítico, por um lado, e o hard-boiled ou policial duro, de outro. Interessa-nos aqui indicar nos dois livros do autor elementos do relato policial citados pelo mesmo, observando como os dois romances, no tocante à narrativa, se assemelham e se distanciam.
Jörn Rüsen e sua contribuição para a didática da história
Authors: Schmidt Maria Auxiliadora 
Published: November 2018

A partir do recorte acerca da obra de Jörn Rüsen no que se refere à sua teoria da aprendizagem histórica, se propõe analisar as contribuições para a pesquisa e para a educação histórica. De um lado, a apropriação destas contribuições, tendo como referência e fundamentação a teoria da História, é algo a ser acolhido e anunciam um novo paradigma para a relação entre aprendizagem e ensino de História, o que se propõe a realizar na primeira parte deste trabalho. De outro, a partir destes pressupostos, foram tomadas como objeto de análise investigações que vem sendo realizadas no Brasil, na área do ensino de História, que têm como referência teórica o pensamento ruseniano. Resultados destas pesquisas, ainda que parciais, indicam várias questões a serem levadas em consideração, no que se refere à aprendizagem das crianças e jovens, seja em ambiente escolar ou outros ambientes de aprendizagem. Ademais, suscitam novas questões de investigação, que também serão apontadas neste trabalho.
As pedras e as cores. Transfigurações do nigredo e jornada circular em Evocações, de Cruz e Sousa
Authors: Araujo Manuella Miki Souza 
Published: November 2018

Ao se valer do princípio alquímico de transfiguração, o poeta Cruz e Sousa conjuga as polaridades da arte e da vida, do criador e da criatura, dos desertos da África e do gélido Polo Norte, sintetizados em imagens derivadas da colorida opala. Em sua tentativa de transfigurar-se, é por meio desse princípio que se articula também a viagem interior do sujeito na obra Evocações, bem como a transição das formas do poema em prosa e da prosa poética, ali cambiantes como as cores do crepúsculo. O presente estudo centra a sua análise no poema em prosa de abertura, denominado “Iniciado”, em especial em seu primeiro parágrafo, que serve de prelúdio cifrado para a totalidade do difuso enredo, desdobrado ao longo dos variados 33 textos que compõem o livro em questão. Neste primeiro parágrafo, o eu poético transgride a rigorosa sequência de transformações da Grande Obra, quando desloca a etapa final do rubedo para o começo, e tenta desviar da fase primordial do nigredo, ocultada no desfecho de sua operação estética. Esse movimento de inversão é análogo àquele do poeta viajante, que foge de sua primeira natureza, identificada à mãe negra, mas acaba por confrontá-la nos textos derradeiros de Evocações
On the Nonlinearity of Winter Northern Hemisphere Atmospheric Variability
Authors: Hannachi A. , Iqbal W. 
Published: November 2018

AbstractNonlinearity in the Northern Hemisphere’s wintertime atmospheric flow is investigated from both an intermediate-complexity model of the extratropics and reanalyses. A long simulation is obtained using a three-level quasigeostrophic model on the sphere. Kernel empirical orthogonal functions (EOFs), which help delineate complex structures, are used along with the local flow tendencies. Two fixed points are obtained, which are associated with strong bimodality in two-dimensional kernel principal component (PC) space, consistent with conceptual low-order dynamics. The regimes reflect zonal and blocked flows. The analysis is then extended to ERA-40 and JRA-55 using daily sea level pressure (SLP) and geopotential heights in the stratosphere (20 hPa) and troposphere (500 hPa). In the stratosphere, trimodality is obtained, representing disturbed, displaced, and undisturbed states of the winter polar vortex. In the troposphere, the probability density functions (PDFs), for both fields, within the two-dimensional (2D) kernel EOF space are strongly bimodal. The modes correspond broadly to opposite phases of the Arctic Oscillation with a signature of the negative North Atlantic Oscillation (NAO). Over the North Atlantic–European sector, a trimodal PDF is also obtained with two strong and one weak modes. The strong modes are associated, respectively, with the north (or +NAO) and south (or −NAO) positions of the eddy-driven jet stream. The third weak mode is interpreted as a transition path between the two positions. A climate change signal is also observed in the troposphere of the winter hemisphere, resulting in an increase (a decrease) in the frequency of the polar high (low), consistent with an increase of zonal flow frequency.
A Theory for the Seasonal Predictability Barrier: Threshold, Timing, and Intensity
Authors: Liu Zhengyu , Jin Yishuai , Rong Xinyao 
Published: November 2018

AbstractA theory is developed in a stochastic climate model for understanding the general features of the seasonal predictability barrier (PB), which is characterized by a band of maximum decline in autocorrelation function phase-locked to a particular season. Our theory determines the forcing threshold, timing, and intensity of the seasonal PB as a function of the damping rate and seasonal forcing. A seasonal PB is found to be an intrinsic feature of a stochastic climate system forced by either seasonal growth rate or seasonal noise forcing. A PB is generated when the seasonal forcing, relative to the damping rate, exceeds a modest threshold. Once generated, all the PBs occur in the same calendar month, forming a seasonal PB. The PB season is determined by the decline of the seasonal forcing as well as the delayed response associated with damping. As such, for a realistic weak damping, the PB season is locked close to the minimum SST variance under the seasonal growth-rate forcing, but after the minimum SST variance under the seasonal noise forcing. The intensity of the PB is determined mainly by the amplitude of the seasonal forcing. The theory is able to explain the general features of the seasonal PB of the observed SST variability over the world. In the tropics, a seasonal PB is generated mainly by a strong seasonal growth rate, whereas in the extratropics a seasonal PB is generated mainly by a strong seasonal noise forcing. Our theory provides a general framework for the understanding of the seasonal PB of climate variability.
Testing the Influence of Recent Weather on Perceptions of Personal Experience with Climate Change and Extreme Weather in New York State
Authors: Fownes Jennifer R. , Allred Shorna B. 
Published: November 2018

Abstract
The general public’s perceptions of climate change may be shaped by local climate impacts through the mechanism of experiential processing. Although climate change is a long-term global trend, individuals personally experience it as weather from moment to moment. This study assesses how New York State adults’ overall perceptions of their personal experiences with the effects of climate change and extreme weather (surveyed in early 2014) are related to recent weather conditions. This research is unique in that it examines multiple types of weather: temperature and precipitation, over 1 day or 1 week, quantified both as relative and nonrelative measures. Respondents’ perceptions that they had personally experienced climate change or extreme weather significantly increased with warmer relative (percentage of normal) minimum temperatures on the day of the study. Maximum temperatures and total precipitation levels were not significant predictors of perceptions of personal experience, either on the day of the study or over the preceding week. Experiential processing had a smaller effect on perceptions than motivated reasoning, the influence of preexisting ideas. Respondents who believed that climate change was happening agreed more that they had personally experienced it or extreme weather, and this effect increased for individuals who thought that climate change was anthropogenic, as opposed to naturally caused. Of the sociodemographic factors assessed here, political party, gender, and region were significant predictors, while age and education were not.

Published: November 2018

Purpose: A popular method for enhancing medication management within a patient-centered medical home (PCMH) is the physician–pharmacist collaborative management (PPCM) model. To improve efficiency of health-care delivery within 4 federally qualified health centers (FQHCs), the PPCM model was implemented through coordinated physician–pharmacist covisits. Objective: To evaluate the impact of physician–pharmacist covisits on clinical outcomes among patients with uncontrolled diabetes. Methodology: This was a retrospective multicenter cohort study including adults (≥18 years old) with uncontrolled type 1 or type 2 diabetes (hemoglobin A1c [HbA1c] ≥ 8 %) who had at least one covisit between January 1, 2013, and October 1, 2016. The primary clinical metric was mean change in HbA1c from baseline to follow-up. Secondary outcomes included adherence to select American Diabetes Association (ADA) Standards of Medical Care. Results: A total of 106 patients were included in this analysis. Patients who were managed in the PPCM model experienced a significant decrease in mean change in HbA1c from baseline to follow-up (−1.75 [2.63], P < .001). There was no significant difference in the proportion of patients receiving recommended vaccinations or cardiovascular (CV) risk reduction medications. Conclusion: The results suggest that physician–pharmacist covisits may improve glucose control in patients with uncontrolled diabetes.
Death attitudes and truth disclosure: A survey of family caregivers of elders with terminal cancer in China
Authors: Tang Yong 
Published: November 2018

Background: Although family caregivers play an important role in end-of-life care decisions, few studies have examined the communication between family caregivers and patients at the end of life. Objective: The objective was to describe family caregivers’ attitudes toward death, hospice, and truth disclosure. Research design: A quantitative method was used, and a closed-ended survey of 140 family caregivers was conducted in China. The subjects included 140 primary family caregivers of elders with terminal cancer enrolled at a hospice center from April to August 2017. Participants: 140 primary family caregivers of elders with terminal cancer participated the study. Research Context: A high proportion of cancer patients continue to receive inadequate information about their illness. Family caregivers’ inhibitions about disclosing information to cancer patients have not yet been the objects of research in China. Ethical considerations: This study was reported to and approved by the Regional Ethics Committee in Shenzhen, China. Findings: A questionnaire survey collected information on family caregivers’ background information, emotional state, personal needs, death attitudes, and truth-disclosure opinions. The results revealed that family caregivers’ death attitudes and truth-disclosure opinions played an important role in the process of caring for elders with terminal cancer. Discussion: By adopting a quantitative method, the author revealed not only the general patterns of family caregivers’ attitudes toward cancer diagnosis disclosure but also the reasons for their actions and the practices of family disclosure. Conclusion: The findings suggested that ineffective communication concerning end-of-life issues resulted from family caregivers’ lack of discussion and difficulty in hearing the news. Future studies should examine strategies for optimal communication between family caregivers and patients, especially with regard to breaking the bad news. Professional training in breaking bad news is important and is associated with self-reported truth-disclosure practices among family caregivers.

Introduction This study explores a novel smartphone application for postoperative care following carpal tunnel release (CTR). We hypothesized that a software-based ‘virtual visit’ for CTR could be safe, effective and convenient for the patient. Methods Our group developed the software application utilized in this study. Interactive steps with video instructions enabled patients to complete dressing and suture removal, capture a wound photo, answer a question about median nerve symptoms and capture a video of finger range of motion. Adult patients undergoing endoscopic or open CTR were enrolled. Prior to their scheduled postoperative visit, patients received and completed the module using their smartphone. Agreement between findings of the virtual visit and the corresponding in-person clinical visit was assessed using kappa values. Results Twenty-two patients were contacted regarding study enrolment and 17 patients were enrolled (ages 23–63, mean 48.2, 6M, 11F). Of 16 patients who participated, all completed dressing removal. Ten of 16 patients removed their sutures successfully. Fourteen patients captured a clinically adequate wound photo and 15 patients answered a question about median nerve symptoms. Fourteen patients captured a range of motion video. Software assessments of surgical wounds, nerve symptoms and physical exams agreed strongly with clinical assessments. Discussion Most patients were able to respond to a question about their symptoms, provide clinical assessment of their wound via a photo and record a video of their range of motion. Suture removal was the most difficult task. More investigation is needed to determine which patients can reliably remove their sutures.
Multipass Beta Filtration Testing for the 21st Century
Authors: Eleftherakis John G. , Khalil Abraham 
Published: November 2018

The current ISO 4572 Multipass Filter Test Procedure has not been substantially revised since its approval as an ISO document in 1981. However, proposed revisions will likely be adopted shortly which will have far-reaching impact in liquid multipass filter testing and for virtually all industrial applications. These revisions include the adoption of a new test dust to replace the discontinued AC Fine Test Dust (ACFTD), a revised particle counter calibration procedure using National Institute of Standards & Technology (NIST) traceable calibration fluid, a new on-line particle counter, sample delivery and dilution system validation procedure, and a new reporting format. These changes result in a new definition for assessing and rating filter performance. This paper discusses these changes in detail and the resulting impact on the filtration industry. For example, the most significant revision pertains to use of a revised ISO 4402 standard for calibration of liquid particle counters. Until now, particle counter calibration fluid containing ACFTD was used to calibrate particle counters. This test dust is no longer manufactured due, in part, to the inability of the manufacturer to produce a consistent particle distribution of ACFTD from one batch to another. This inconsistency in the test dust, and also in much of the calibration fluid containing the test dust, created a great challenge for labs to correlate particle count results and filter test data. The revised ISO 4402 calibration standard will require the use of a new NIST Standard Reference Material (SRM) calibration fluid using a new test dust called ISO Medium dust, which has virtually replaced ACFTD. This new test dust and the calibration fluid containing it is much more consistent and reliable, allowing for better correlation of results. The analysis conducted by NIST to certify the calibration fluid as a SRM found what before was defined as a 2 micron particle was actually a 4.6 micron particle and what was defined as a 15 micron particle was actually a 13.6 micron particle. This finding will redefine liquid filter performance information based on particle counts to the effect that, in general, fine filters will appear less efficient than previously reported and coarse filters will appear more efficient. While other revisions to ISO 4572 will have less impact, they are presented. Filter test engineers, filter users and manufacturers, and filter sales personnel will benefit by educating themselves now on the impact of these revisions in order to best serve the filtration industry and filter users.
Effects of Fiber Denier, Fiber Cross-Sectional Shape and Fabric Density on Acoustical Behavior of Vertically Lapped Nonwoven Fabrics
Authors: Tascan Mevlut , Vaughn Edward A. 
Published: November 2018

Acoustical insulation and absorption properties of nonwoven fabrics depend on fiber geometry and fiber arrangement within the fabric structure. The different structures of the fibers result in different total surface areas of nonwoven fabrics. Nonwoven fabrics such as vertically lapped fabrics are ideal materials for use as acoustical insulation products, because they have high total surface. Vertically lapped nonwoven technology consists of carding, perpendicular layering of the carded webs, and through-air bonding using synthetic binder fibers. The surface area of the fabric is directly related to the denier and cross-sectional shape of the fibers in the fabric. Smaller deniers yield more fibers per unit weight of the material, higher total fiber surface area, and greater possibilities for a sound wave to interact with the fibers in the fabric structure. The research in the literature uses two methods for measuring acoustical properties of fabric materials: the impedance tube and reverberation room method. Small test samples are in the impedance tube method and sound absorption coefficient is determined at each frequency. Large reverberation rooms and large test samples are used for the reverberation room method. A direct comparative acoustical properties measurement device that was designed and fabricated at Clemson University School of Materials Science & Engineering was used to measure acoustical insulation in this research. This paper provides a description of the measurement devices and acoustical measurement data for vertically lapped nonwoven fabrics made from three different polyester fiber shape and two denier levels.
Microwave Radiations for Heat-Setting of Polyester Fibers
Authors: Bhat Narendra Vinayak , Kale Manik J. , Ajit V. Gore 
Published: November 2018

The use of radio and microwave frequency is gaining importance for industrial applications such as heating, drying, and other processing. The most important advantage of using microwave is that it is non-contact or localized heating and the heat is produced within the material. This can be much more effective than indirect heating where the heat propagation is by heat conduction through the material. We have been investigating the influence of microwave radiation on different fibers for the last few years. In the present investigation we used microwave frequency of 2450 MHz to investigate its effect on polyester fibers. The polyester fibers were heat set in air as well as a liquid, which acted as a lossy substances. The liquid was chosen on the basis of earlier experiments, which showed the maximum effect. A comparative study was also carried out using conventional heating in silicone oil. Using the method of X-ray Diffraction (XRD) we calculated the changes in % crystallinity and orientation. It was found that as the time of treatment under microwave radiation increased from 15 sec. to 120 sec. the order factor was found to increase from 0.32 to 0.71. The crystalline orientation as determined from the azimuthal scan was also found to increase. Such structural changes can be highly beneficial for the processing of fabric in industry. The microwave radiation process is fast, reliable and energy saving.

Published: November 2018

The influence of polypropylene fibers has been studied in different proportioning and fiber length to improve the performance characteristics of the lightweight cement composites. Fibers used in two different lengths (6mm and 12mm) and fiber proportions (0.15% and 0.35%) by cement weight in the mixture design. Hardened concrete properties such as: 7- and 28-day compressive strength, splitting tensile strength, flexural strength, water absorption, and shrinkage were evaluated. Fiber addition was seen to enhance the physical and mechanical properties of lightweight concrete. Compared to unreinforced LWC, polypropylene (PP) reinforced LWC with fiber proportioning 0.35% and 12 mm fiber length, caused 30.1% increase in the flexural strength and 27% increase in the splitting tensile strength. Increased fiber availability in the LWC matrix, in addition to the ability of longer PP fibers to bridge on the micro cracks, are suggested as the reasons for the enhancement in mechanical properties.

Authors: Jerkovic Ivona , Pallarés Josep Maria , Ardanuy Monica , Capdevila Xavier 
Published: November 2018

The weight of textile components in automobiles is expected to rise to 35 kg by 2020, and the average lifetime of a vehicle is about 12 years. Car seats are the most important part of the interior decoration, and polyester is the most widely used material in car seat covering. Abrasion resistance tests are used to quantify the duration of car seat upholstery in normal usage, and this is one of the most important requirements. Several testing methods, standards, and car producer specifications have been developed to define the abrasion resistance of specified materials, and pre-tests have been taken to identify parameters for this research. The objective of this study was to compare three abrasion tests with different abrasive elements using car seat upholstery structures. Comparison among abrasion testers and abrasive papers shows statistically significant differences. The relationship between weight loss and abrasion cycles can be modelled by regression equations.
