Arteriogenic Thoracic Outlet Syndrome Presenting as Cervical Radiculopathy
Authors: Todnem Nathan , Kilianski Joseph , Reddy Vamsi , Rahimi Scott
Published: August 2018

Thoracic outlet syndrome (TOS) is an infrequent entity encountered by medical practitioners attributed to compression of the neurovascular structures passing through the thoracic outlet. Here, we report the presentation of a young adult who was referred for workup of cervical radiculopathy and was planned to undergo an anterior cervical discectomy and fusion. A dynamic cerebral angiogram was performed and confirmed the diagnosis of arteriogenic TOS. The etiology, presentation, and diagnostic workup of TOS are briefly discussed with emphasis placed on maintaining a healthy suspicion in order to differentiate from cervical radiculopathy, make an accurate diagnosis, and avoid inappropriate surgery.

Published: August 2018

Intercooled cycle gas turbine has great potential in improving the output power because of the low energy consumption of high-pressure compressor. In order to more efficiently recovery and utilize the waste heat of the intercooled system, an organic Rankine cycle power generation system is developed to replace the traditional intercooled system in this study. Considering the effects of different kinds of organic working fluids, the thermodynamic performance of organic Rankine cycle power generation system is investigated in detail. On this basis, the sensitivity analyses of some key parameters are conducted to study the operating improvements of organic Rankine cycle power generation system. The results indicate that the integration of organic Rankine cycle and intercooled cycle gas turbine not only can be used for waste heat power generation but also increases the output power and efficiency of intercooled cycle gas turbine by selecting the organic working fluids of n-butane (R600), n-pentane (R601), toluene, and n-heptane. And compared to the others, organic Rankine cycle power generation system with toluene exhibits the best performance. The maximum enhancements of output power and thermal efficiency are 6.08% and 2.14%, respectively. Moreover, it is also concluded that both ambient temperatures and intercooled cycle gas turbine operating conditions are very important factors affecting the operating performances of organic Rankine cycle power generation system.
Acadian hinterland-vergent detachment structures in the southwestern Appalachian Plateau: Implications for the Marcellus Shale gas exploration and production
Authors: Gao Dengliang , Donahoe Thomas , Duan Taizhong , Sullivan Peter
Published: August 2018

Three-dimensional seismic data in southwestern Pennsylvania in the Appalachian Plateau demonstrate that the structural style in the Devonian section is dominated by east-vergent folds and reverse faults, which contrasts with that in the Valley and Ridge Province where west-vergent folds and thrusts dominate. Vertical (cross-stratal) variations in fold curvature and fault throw indicate that the intensity of shortening increases from the Salina (Upper Silurian) to the Onondaga (Middle Devonian) and then decreases from the Onondaga to the Elk (Upper Devonian). Lateral (along-stratal) variations in fold curvature and fault throw indicate that the folds and faults tend to propagate in the cross-strike and along-strike directions. Isochron thickness below the Onondaga increases on the anticlinal, up-thrown side of the faults, whereas isochron thickness above the Onondaga increases to the synclinal, down-thrown side of the faults. In concert with seismic structure and isochron thickness, seismic facies see vertical and lateral variations that are spatially and temporally related to folds and faults. Four years of gas production data from the Middle Devonian Marcellus Shale show that the gas productivity drops near the regional reverse faults, whereas regional drilling patterns from a broader perspective of the Plateau reveal operational gaps near major cross-regional wrench faults. These observations are indicative of the dynamic interplay among hinterland-vergent detachment deformation, syntectonic sedimentation, and shale gas preservation during the Acadian (Middle Devonian–Early Mississippian).
Merchant Energy Trading in a Network
Authors: Nadarajah Selvaprabu , Secomandi Nicola
Published: August 2018

We formulate the merchant trading of energy in a network of storage and transport assets as a Markov decision process with uncertain energy prices, generalizing known models. Because of the intractability of our model, we develop heuristics and both lower and dual (upper) bounds on the optimal policy value estimated within Monte Carlo simulation. We achieve tractability using linear optimization, extending near optimal approximate dynamic programming techniques for the case of a single storage asset, versions of two of which are commercially available. We propose (i) a generalization of a deterministic reoptimization heuristic, (ii) an iterative version of the least squares Monte Carlo approach, and (iii) a perfect information dual bound. We apply our methods to a set of realistic natural gas instances. The combination of our reoptimization heuristic and dual bound emerges as a practical approach to nearly optimally solve our model. Our iterative least squares Monte Carlo heuristic is also close to optimal. Compared to our other heuristic, it exhibits slightly larger optimality gaps and requires some tuning, but is faster to execute in some cases. Our methods could enhance single energy storage asset software and have potential relevance beyond our specific application.

Medienreflexion im Musikvideo
Authors: Rehbach Simon
Published: August 2018

Seit seiner Entstehung setzt sich das Musikvideo mit den Charakteristika anderer Medien auseinander. Aufbauend auf dem Konzept der Medienreflexion untersucht Simon Rehbach die Darstellung des Fernsehens in der Bilderwelt kommerzieller Clips. Er differenziert zum einen verschiedene Strategien der Inszenierung der Television und analysiert zum anderen die Perspektiven, unter denen intermediale Bezugnahmen erfolgen. Die Studie zeigt, dass Inhalte, ästhetische Merkmale und Nutzungs- sowie Wirkungsweisen des Fernsehens auch nach dem Ende der Goldenen Ära von MTV einen zentralen Gegenstand der Reflexion des Musikvideos bilden, während sich die Darstellung des Distributionsmediums mit der zunehmenden Verbreitung von Clips im Internet wandelt.

Die digitale Gegenrevolution
Authors: Nagle Angela
Published: August 2018

Im Internet tobt ein neuer Kulturkampf. Auf der einen Seite steht die Neue Rechte (Alt-Right), die von einst obskuren neoreaktionären und rechtsextremen Bewegungen über nerdige Subkulturen wie 4chan bis hin zu Medienstars wie Milo Yiannopoulos reicht und entschieden zu Donald Trumps Wahlsieg 2016 beigetragen hat. Auf der anderen Seite birgt die therapeutische Sprache von »Triggerwarnungen« und »safe spaces« die Gefahr einer Kultur des öffentlichen Tribunals und des demonstrativen »Gutmenschentums«. Angela Nagle erkundet die kulturelle Genealogie dieser Ästhetiken und Subkulturen und zieht Parallelen zu vergangenen politischen Phänomenen. Ihre emphatische Botschaft: Der permanente cultural turn - die Verlagerung von Politik ins Kulturelle in Form von Kulturkämpfen, die die ganze Gesellschaft spalten - muss aufgehalten werden! Das Buch, im englischsprachigen Original mittlerweile ein Bestseller, wurde vom britischen Guardian zu den Büchern des Jahres 2017 gezählt.
Kontroverse Reproduktion
Authors: Banihaschemi Susan
Published: August 2018

Die Etablierung der Reproduktionsmedizin geht einher mit teils massiven Kontroversen. Denn nicht alles, was technologisch und reproduktionsmedizinisch machbar wäre, ist auch gesellschaftlich vorstellbar und zu legitimieren. So wurde die reproduktionsmedizinische Behandlung mit Spendersamen in der deutschen Ärzteschaft lange als standesunwürdig verhandelt - sie konnte sich nur nach und nach zu einer anerkannten medizinischen Behandlungsform bei Infertilität des Mannes entwickeln. Susan Banihaschemi zeigt in ihrer Diskursanalyse auf, dass die Etablierung der Samenspende von kontroversen Aushandlungs- und Legitimierungsprozessen begleitet war, in denen auch Vorstellungen und Wissen von als natürlich gesetzten Beziehungen und von der Reproduktion der Geschlechter verhandelt werden.

Physical activity and physical fitness as protective factors of adolescent health
Authors: Lukács Andrea , Sasvári Péter , Kiss-Tóth Emőke
Published: August 2018

Objective

This quantitative correlational design study aimed to examine the variation in adolescent health and lifestyle characteristics across self-reported physical activity (PA) and physical fitness (PF) levels.

Methods

Data were collected from 422 students (50.2% males) (16.33 SD = 1.66 y/o) attending a high school. An online questionnaire was used to gather data on the following characteristics: self-reported well-being, overall life satisfaction, depression (including self-harm and suicidal ideation), perceived health status, eating disorders, sleepiness, substance use (alcohol, tobacco and illicit drug use), body mass index, PA participation and PF levels.

Results

Of the participants, 42.4% reported at least 5 days of PA a week for 60 min per day. These high active individuals had significantly better well-being, health status, life satisfaction, PF and consumed fewer alcohol beverages. High PA and better PF inversely correlated with depression.

Conclusions

It seems that high PA and better PF have a positive impact on adolescent perceived health, health-risk behaviors and mental health. Increased levels of PA can play a vital role in the primary care, prevention of health risks and in adolescent health promotion. Accordingly, educational institutions are an excellent setting to promote and provide sport facilities and encourage students to be more physically active.
Natural colloid mobilization and leaching in wettable and water repellent soil under saturated condition
Authors: Sepehrnia Nasrollah , Fishkis Olga , Huwe Bernd , Bachmann Jörg
Published: August 2018

The coupled transport of pollutants that are adsorbed to colloidal particles has always been a major topic for environmental sciences due to many unfavorable effects on soils and groundwater. This laboratory column study was conducted under saturated moisture conditions to compare the hydrophobic character of the suspended and mobilized colloids in the percolates released from a wettable subsoil and a water repellent topsoil. Both soils with different organic matter content were analyzed for wettability changes before and after leaching using sessile drop contact angles as well as water and ethanol sorptivity curves, summarized as repellency index. Hydrophobicity of the effluent suspensions was assessed using the C18 adsorption method. Water repellency level of the repellent soil decreased after leaching but remained on a lower level of water repellency, while, the wettable soil remained wettable. The leached colloids from the repellent soil were predominantly hydrophilic and the percentage of the hydrophobic colloid fraction in the effluent did not systematically changed with time. Total colloid release depended on soil carbon stock but not on soil wettability. Our results suggest that due to the respective character of transported colloids a similar co-transport mechanism for pollutants may occur which does not depend explicitly on soil wettability of the releasing horizon, but could be more affected by total SOM content. Further studies with a wider range of soils are necessary to determine if the dominant hydrophilic character of leached colloids is typical. Due to the mostly hydrophilic colloid character we conclude also that changes in wettability status, i.e. of wettable subsoil horizons due to the leachate, may not necessarily occur very fast, even when the overlaying topsoil is a repellent soil horizon with a high organic matter content.
Electron Work Functions of (H K L)-Surfaces of W, Re, and Cu Crystals
Authors: Surma S.A. , Brona J. , Ciszewski A.
Published: August 2018

Work function (WF) and some physicochemical data for several most prominent crystal planes of three metals of typical structures are calculated within the linear approximation employing the surface dipole and 2D gas models. “Composite” crystal of a homogeneous bulk phase and a thick surface composed of eight (h k l)-oriented facets with different unsaturated bonds is treated as a nine-phase nine-component system with two degrees of freedom. It contains the two-dimensional metal-lattice plasma of free electrons and the immobile atom-core network. For twenty four (h k l) surfaces, the WF and dipole barrier term, chemical and electrostatic potential levels, electron charge densities, surface dipole fields, and other parameters are calculated and tabularized. WF values obtained from the thermodynamics based formula are compared to the ones obtained from the quantum mechanics based formula, which shows good agreement with experiment and also reveals a specific deviation in the case of field emission method for the most packed plane. A set of accurate face dependent data can be of interest to electronics and materials science workers
Field Permeability Tests: Importance of Calibration and Synchronous Monitoring for Barometric Pressure Sensors
Authors: Zhang Lu , Chapuis Robert P. , Marefat Vahid
Published: August 2018

Pressure transducers (PTs) and an atmospheric pressure transducer (APT) were used to register test data during two types of permeability tests, which were performed in 14 wells monitoring a confined aquifer installed in the lab, and a field rising-head test in clay. The constant-head tests were performed using a peristaltic pump and thus functioned as constant flow rate tests until stabilization of the water level in the well riser pipe. The rising-head tests were started by the sudden removal of a slug of water. This article presents, first, the method used to calibrate the transducers to assess their systematic calibration error (offset) values. Then, it quantifies the influence of synchronized monitoring for the (PT-APT) pair on short- and long-term test data, which had never been done before. The results indicate that the pair calibration cannot be neglected and that the synchronized monitoring is important for all tests, except maybe for a short-duration variable-head test. For most tests, however, the barometric fluctuation with time plays a significant role.
Lithium Extraction to Determine Ammonium in the Exchange Complex of Bentonite
Authors: Setz Melissa C. , Benson Craig H. , Bradshaw Sabrina L. , Tian Kuo
Published: August 2018

ASTM D7503, Standard Test Method for Measuring the Exchange Complex and Cation Exchange Capacity of Inorganic Fine-Grained Soils, is used to determine soluble and bound cation concentrations as well as the cation exchange capacity of fine-grained soils used in barrier systems for waste containment, including bentonite in geosynthetic clay liners (GCLs). ASTM D7503 prescribes the use of 1 M ammonium acetate (NH4OAc) as an extraction liquid for bound cations, which masks ammonium (NH4+) that may be in the exchange complex in bentonite in contact with municipal solid waste (MSW) leachate. A 1 M lithium bromide (LiBr) extraction liquid is proposed as an alternative to the 1 M NH4OAc in ASTM D7503 so that NH4+ in the exchange complex can be quantified without interfering with measurement of other bound cations of interest for waste containment. Nearly the same distribution of bound major cations was obtained using the method in ASTM D7503 and the proposed alternative using 1 M LiBr for two bentonites from two new GCLs (not permeated). Using the 1 M LiBr method revealed substantial NH4+ bound to eight bentonites obtained from GCLs that had been permeated with different MSW leachates. The bound NH4+ concentration varied directly with NH4+ concentration in the leachates, and this variance explained a charge imbalance obtained from tests conducted on the bentonites using the standard method in ASTM D7503.

We carried out MIC of the derivatives of 1,2,4-triazole II (4-((5-nitrofuran-2-yl)methyleneamino)-1-propyl-4H-1,2,4-triazolium bromide) and I (N-((5-nitrofuran-2-yl)methylene)-4H-4-amino-1,2,4-triazolidium chloride) against Escherichia coli ATCC 3912/4 and E. coli k88ad, Staphylococcus aureus ATCC 25923 and S. aureus k99, Klebsiella pneumonia k56 and Salmonella typhimurium 144, S. enteritidis. All test cultures were sensitive to compound II at concentrations of 1,25–0,039 μg/ml. Similar MIC (0,039 μg/ml) of compounds II and I were set for E. coli k88a and S. aureus k99 test cultures – 0,156 μg/ml. Only S. aureus ATCC 25923 and K. pneumonia k56 had sensitivity to ceftriaxone (MIC = 0,097 μg/ml). Antiviral activity of Trifuzol (piperidine 2-[5-(furan-2-il)-4-phenil-1,2,4-triazol-3-ilthio]acetate) and avistim (morpholines 3-(4-pyridyl)-1,2,4-triazolil-5-thioacetate) against the chicken infectious bronchitis virus (VIB) strain 4/91 was characterized by a decrease in mortality and pathological changes of chicken embryos (CE) which were induced by the virus. Death of infected CE provoked by the strain 4/91 of VIB in dilution 10–3 occurred at 57.1%. The reduction in the percentage of deaths of CE infected by the virus in dilution 10–3 in the presence of Avistim was 28.6%, and with Trifuzol 14.3%. The use of avistim and Trifuzol compounds reduced VIB infectious activity when it was cultivated in CE, reducing the titre of the virus (strain 4/91) by 3 lg EID 50 cm–3.
The effect of third-generation aromatase inhibitors on aromatase avtivity in visceral adipose tissue
Authors: Lytkin D. V. , Zagayko A. L. , Briukhanova T. O.
Published: August 2018

Pathogenesis and clinical manifestations of metabolic syndrome (and other conditions characterized by the growth of fat mass and decreased adiponectin content) is associated with an imbalance of sex hormones, which develops under the influence of increased aromatase activity in adipose tissue. Drugs of the aromatase inhibitors therapeutic group are able to suppress the course of the aromatase reaction in the central and peripheral organs and tissues. The aim of our study was to establish the relationship between levels of serum adiponectin and adipose tissue aromatase avtivity in Syrian hamsters of different ages and gender with experimental metabolic syndrome and study the effect of aromatase inhibitors on these indicators. Experimental metabolic syndrome in animals was induced by a high-fat and fructose diet. The drugs were administered during the 21-st day in doses of 3.086 (exemestane), 0.309 (letrozole) and 0.126 mg/kg (anastrozole). The aromatase activity of the visceral adipose tissue was determined by the modified kinetic method based on the amount of the reaction product estradiol converted from testosterone. The content of estradiol in adipose tissue homogenate and serum adiponectin levels were measured by the immune enzyme method. The results showed a high inverse correlation between serum adiponectin and adipose tissue aromatase activity in hamsters. Aromatase inhibitors caused a decrease in the adipose tissue aromatase activity and increase in serum adiponectin levels. Letrazol demonstrated the greatest effect, it reduced aromatase activity in adipose tissue by 72–84% and increased serum adiponectin content by 1.6–1.8 times. At the same time, intra-group correlation of the studied parameters was significant. The results show the relationship between adiponectin level and adipose tissue aromatase activity and ability to change these rates by the way of aromatase inhibitors, which may be useful in clinical practice. Third-generation aromatase inhibitors are promising drugs for metabolic syndrome treatment and require further study in clinical trials.

This study is related to the electrochemical oxidation of NaBH4 on Au, Pt, Pd and Ni electrodes by the use of cyclic and square wave voltammetry. The most effective metal for the oxidation of sodium borohydride was found to be Au. Pt and Pd electrodes also showed certain activity while Ni was not effective. The compound was observed to give two consecutive oxidation steps with 6 and 2 electron transfers. The experiments conducted while keeping the potential at −0.8V showed that the resulting compound is adsorbed upon the electrode surface and gradually decrease its catalytic activity.
Four Years of Experience Using Problem-Based Learning as a Platform to Develop Student Teaching Skills: A Preliminary Report
Authors: Lupi Carla , Ward-Peterson Melissa , Castro Christian , Splinter Ansley
Published: August 2018

This article was migrated. The article was marked as recommended. Introduction: A graduating medical student should be competent in both teaching and communication skills. This concept is supported by the Accreditation Council for Graduate Medical Education and the Association of American Medical Colleges. Our study describes how we utilized problem-based learning as a platform for developing student teaching skills and to examine preliminary outcomes. Methods: Since 2013, third-year medical students at Florida International University Herbert Wertheim College of Medicine have participated in a mandatory problem-based learning course in parallel to their clinical rotations. During the course orientation students have been led through interactive sessions on writing learning objectives and methods for effective micro-teaching sessions. During seven subsequent sessions, trained faculty members have assessed and provided narrative comments on students' "Ability to Teach Peers" using an anchored developmental scale rubric. Data from four academic years were available for analysis. The Wilcoxon signed-rank test was used to test differences between the initial and final sessions. Results: At the initial session, 39.0% (n=147) received ratings of "mastering." By the final session, 62.6% (n=236) received ratings of "mastering." Conclusion: Our preliminary work demonstrates that a brief orientation to micro-teaching followed by repeated mandatory practice and feedback within our problem-based learning curriculum may serve to build students' teaching skills.

Published: August 2018

This article was migrated. The article was marked as recommended. Background: Interpreters may offer valuable perspectives on ways clinicians could improve communication skills. Relationship-centered communication (RCC) curricula are based on a framework for promoting effective communication both with patients and within health care teams. Methods: We conducted a 90-minute workshop with certified interpreters at an academically-affiliated safety-net system to solicit feedback to optimize RCC skills trainings for clinicians at a U.S. academically-affiliated safety-net system. We applied an editing analysis style to transcribed quotes to reveal opportunities to optimize RCC skills trainings to improve safety-net care for diverse populations. Results: Twenty-two Spanish-, Cantonese-, Mandarin-, Vietnamese-, and Russian-speaking interpreters participated. Overall, interpreters emphasized the importance of creating a supportive environment for safety-net patients. One Spanish-speaking interpreter added: "When they get up in the morning and go to work, they may get deported. So, that's important to create an atmosphere to help them open up. And they may tell you stuff that's directly pertinent to patient care." Thematic analysis revealed opportunities to tailor and reinforce each RCC stage. On agenda-setting and rapport-building: "We need a little background on the phone, and we don't know how many people are in the room ... Sometimes you're talking to the mom, but the doctor didn't even bother to say it.. [If] we're lost, we're bound to make mistakes." On eliciting the patient's perspective: "Start with this information so they know you're still going to give them your advice: "I'm going to let you know what I think is going on, but what do you think is going on?" On negotiating a shared plan: "[Teachback] is really important. Otherwise it puts an incredible burden on the interpreter ... I'm not sure that the patient really understood." Conclusions: Teaching RCC in partnership with medical interpreters could provide opportunities to deepen clinician RCC skills for more effective patient-interpreter-clinician interactions.

Resumo Analisou-se a qualificação de profissionais da saúde para a atenção às mulheres em situação de violência sexual em duas capitais brasileiras, em estudo qualitativo envolvendo 140 profissionais de diferentes categorias de 18 instituições de saúde em Fortaleza e Rio de Janeiro. Entrevistas semiestruturadas foram realizadas e o material empírico foi analisado segundo a técnica de análise de conteúdo. Lacunas na formação dos profissionais decorrentes da insuficiente abordagem do tema durante a graduação dos cursos da área da saúde foram observadas nos dois municípios. A fragilidade da qualificação profissional para esse tipo de atuação foi reforçada por lacunas nas ações de capacitação. No município do Rio de Janeiro essas ações mostraram-se mais frequentes e contínuas. Importante a inclusão do tema na formação profissional, a ampliação de processos de capacitação e a atualização das equipes de saúde nos serviços.

ABSTRACT Ameloblastoma is a benign, odontogenic tumor that, due to its low rate of incidence, slow growth and local invasiveness, can be treated with a variety of surgical approaches, ranging from conservative to radical procedures. The conventional variant of ameloblastoma, though, is more aggressive and common, presenting a higher rate of recurrence than the unicystic and extraosseous/peripheral types; usually, the treatment of choice for this variant employs more invasive procedures. This report is of a 13-year-old male patient who presented with a swelling on the posterior mandibular region, on the left side of his face. Intraoral examination revealed lingual displacement of teeth 36 and 37. The clinical, radiographic and histopathological analyses confirmed the diagnosis of ameloblastoma (plexiform histological type). The patient was treated with curettage and peripheral osteotomy and a 5-year follow-up examination showed the area to have healed completely, with no evidence of recurrence. Consequently, although the clinical management of ameloblastoma is often based on invasive surgical approaches, large tumors treated with conservative surgery are less aesthetically and functionally impaired, and may demonstrate good prognosis with no recurrence in the 5-year follow-up period, as in the case reported here.

ABSTRACT Objective: This study analyzed the influence of the irrigating solutions ultrasonic activation on the obturator cement penetration into lateral root canals. Methods: Fifty maxillary molars (palatine root) were randomly assigned to 5 experimental groups (Group 1 (EDTA 17% + manual agitation for 5 minutes), Group 2 (EDTA 17% + ultrasonic activation for 15 seconds), Group 3 (NaOCl 1% + Ultrasonic activation for 15 seconds), Group 4 (EDTA 17% + ultrasonic activation for 15 seconds and NaOCl 1% + ultrasonic activation for 15 seconds) and Group 5 (negative control). The lateral root canals were made in the apical and middle third. The obturation occurred in a single session. The radiographic and microscopic analyzes were performed to evaluate the sealant cement penetration degree. Data were analyzed by the Mann-Whitney and Wilcoxon tests. Results: Apical and middle third radiographic analysis showed that Groups 2 and 4 presented better penetration of the sealant cement. In the microscopic analysis, Group 4 presented superior results in relation to the other groups in both thirds. In the apical third, radiographic and microscopic analyzes showed significant differences in the comparisons between Group 4 and Groups 5 (p = 0.019) and 3 (p = 0.023) and between Group 5 and Groups 2 (p = 0.012), 3 (P = 0.038) and 4 (p = 0.019), respectively. Conclusion: It was concluded that the ultrasonic activation of the NaOCl 1% + EDTA 17% irrigation solution provides greater penetration of the endodontic cement in lateral root canals.
Diálogos entre bioética e saúde global: análise de usuários e usos de parques urbanos como indicadores éticos na promoção de bem-estar

Resumo Embora as áreas verdes urbanas levem a benefícios biopsicossociais, a inserção em ambientes estigmatizados pode gerar vulnerabilidades. Este texto objetivou caracterizar os usuários e usos do passeio público de Curitiba por meio de pesquisa quantitativa da percepção e de condutas dos visitantes. Os resultados atestaram que o Parque está atrelado a referenciais emocionais, contudo a identificação de riscos tem conduzido a substituição por parques mais modernos. Famílias ainda frequentam o parque usufruindo dos animais para interação, no entanto essa satisfação as impede de perceber questões éticas. O conflito entre a importância do espaço para o cidadão e as vulnerabilidades sociais e dos animais conclama pela intervenção da bioética ambiental na intermediação do diálogo com a saúde global visando subsidiar o estabelecimento de uma solução consensual e justa para todos.
Vetores em contradição: planejamento da mobilidade urbana, uso do solo e dinâmicas do capitalismo contemporâneo
Authors: Cruz Maurício Feijó , Fonseca Francisco César Pinto da
Published: August 2018

Resumo Este artigo analisa as relações entre as atividades de planejamento urbano no Brasil – em especial da mobilidade urbana e do uso do solo – tensionadas pelas dinâmicas do capitalismo pós-fordista, representando modelo de acumulação ao qual o planejamento governamental tende a se adaptar, embora num processo permanente de embates e contradições. Tendo em vista a Política Nacional de Mobilidade Urbana e o Estatuto da Metrópole, e à luz dos processos de espraiamento territorial dos aglomerados urbanos em escala regional, procura-se compreender perspectivas e diretrizes para que o planejamento da mobilidade urbana e metropolitana, objeto dos Planos Municipais de Mobilidade Urbana e Planos de Desenvolvimento Urbano Integrado, superem abordagens setoriais de transporte alheias à realidade advinda das dinâmicas do capital no espaço urbano.

ABSTRACT Objective: To evaluate the direct costs of transforaminal lumbar interbody fusion (TLIF) and minimally invasive surgery (MIS) or open technique (OPEN). Methods: The present study is descriptive and retrospective. Sixteen patients with degenerative spinal pathology operated on with the TLIF MIS technique and TLIF OPEN were included over a 13-month period. Days of hospital stay, blood loss, surgical time, medical care and costs were compared. Results: The mean number of days of hospital stay was 6.7 ± 4.3 days with TLIF MIS and 11.1 ± 6.5 days with TLIF OPEN. The blood loss was 307 ± 81.6 ml (range 200400 ml) with TLIF MIS and 803 ± 701.3 ml (range 200-1800 ml) with TLIF OPEN. The surgical time was 320 ± 92.6 minutes (range 210-500 minutes) in TLIF MIS and 372 ± 95.2 minutes (280-540 minutes) in TLIF OPEN. Conclusions: The difference in surgical costs and time between the two procedures was not statistically significant. There was less bleeding during the TLIF-MIS surgery, as well as a correlation between shorter days of hospital stay proportional to bleeding and surgical time, which translates into a reduction in the cost of these items. Level of Evidence III; Analysis based on alternatives and limited costs.

Authors: Carniel Bugs Ricardo
Published: August 2018

Los organismos independientes de regulación vienen consolidándose a escala global como actores esenciales para el correcto funcionamiento de los medios audiovsiuales. Además de supervisar el cumplimiento de las normas y sancionar los canales que emiten contenidos que vulneran derechos fundamentales o considerados nocivos a la audiencia, cada vez más reguladores desarrollan reglas positivas, fomentando valores deseados en la programación de la TV. Este artículo analiza el caso francés del Conseil Supérieur de l'Audiovisuel y sus acciones para mejorar la representación de la diversidad social en los contenidos audiovisuales. Los resultados indican que este tipo de regulación puede modificar viejos hábitos de los medios y contribuir a un discurso más equitativo en la televisión.
A pantomima e sua elipse temporal: da antiguidade grega a Deleuze

Published: August 2018

Ainda que o gesto seja, por vezes, problematizado, o é na forma em que busca comunicar e/ou ilustrar. Este artigo apresenta outro ângulo do gesto, priorizando a situação em que ele não seja controlado pela razão. Trata-se da situação expressa pelo conceito de pantomima apresentado por Deleuze, conceito que se respalda em um sentido antigo da palavra ao mesmo tempo em que deste diferencia-se. O artigo relaciona o conceito antigo, encontrado na Grécia antiga, com o criado pelo mencionado autor.
A novela “Lado a Lado” e as narrativas negras sobre o passado, o presente e o futuro do Brasil
Authors: Siani Ana Carolina , Borges Rosangela Ferreira de Carvalho
Published: August 2018

O presente artigo tem como objetivo compreender as potenciais relações entre a telenovela “Lado a Lado” (Rede Globo, 2012) e o ano de 2012, tendo em vista a responsividade da telenovela como enunciado e considerando-a como uma obra de arte que se emprenha de sentidos em sua relação com a dimensão extra-verbal mais ampla (VOLOCHÍNOV [BAKHTIN], 2009; BAKHTIN, 2011; VOLOCHÍNOV, 2013). Assim, em se tratando de uma telenovela de época, ambientada, na maior parte da narrativa em 1910, compreendemos em que medida a trama estabelece pontes com discursos em circulação na sociedade brasileira de 2012; e, sobretudo, ao tratar o racismo e as desigualdades raciais, produz dizeres tanto sobre os prejuízos históricos atuais da população negra brasileira, como também refere-se a uma ordem social futura.
Futuros presentes: a ficção distópica como reflexo do cotidiano
Authors: Souza Juliana , Costantino Fernanda , Ferreira Emmanoel
Published: August 2018

Resumo: O artigo apresenta a distopia enquanto gênero literário como reflexo do cotidiano, em narrativas que, em um primeiro momento, abordam um futuro imaginado. Nas distopias, esse futuro é encarado sempre como pior que o presente, porém, o que esse trabalho busca tencionar é o quanto tais narrativas já apresentam uma descrença com o próprio cotidiano do momento presente de escrita e apresentação da obra. Para tal, buscamos em um primeiro momento conceituar o gênero distópico e, após, trabalhar a noção de cotidiano, a partir dos autores Agnes Heller e Michel de Certeau, relacionando tais conceitos com as obras distópicas Nós, 1984 e Jogos Vorazes.

Abstract: The article presents dystopia as a literary genre and a reflection of everyday life in narratives that, at first, approach an imagined future. In dystopias, this future is always faced as worse than present, but what this study seeks to demonstrate is how these narratives already present a disbelief with everyday life of the present moment of writing and presentation of the story. To achieve this, we first sought to conceptualize the dystopic genre and, afterwards, to work on the notion of everyday life, from the authors Agnes Heller and Michel de Certeau, relating such concepts to the dystopic narratives We, 1984 and Hunger Games.

Resumen: El artículo presenta el género literario de la distopía como reflejo de lo cotidiano, a partir de narrativas que, en un primer momento, abordan un futuro imaginado. En las distopías, ese futuro es encarado siempre como peor que el presente, pero, lo que ese trabajo busca pretender, es mostrar cuanto tales narrativas ya presentan una incredulidad con el propio cotidiano del momento presente de escritura y presentación de la obra. Buscamos, en un primer momento, conceptuar el género distópico y, después, trabajar la noción de cotidiano, a partir de los autores Agnes Heller y Michel de Certeau, relacionando tales conceptos con las obras distópicas Nosotros, 1984 y Los Juegos del Hambre.
