La práctica de la cita en Alberto Ginastera
Authors: Sottile Antonieta
Published: November 2016

La cita de materiales del folklore constituye una  característica principal del nacionalismo musi- cal en general y de la obra nacionalista de Gi- nastera en particular. Sin embargo, la práctica  de la cita musical en Ginastera no se limita al  folklore sino que se extiende a otras dos fuen- tes: a la música de la tradición culta europea y  a la propia obra anterior de Ginastera. En este  artículo nos proponemos examinar el uso rele- vante que Ginastera hace de estos tres tipos de  cita, la folklórica, la «erudita» y la autocita a lo  largo de toda su producción, atravesando sus  diferentes períodos. La cita «erudita» aparece  muy presente en la obra de Ginastera a partir  del  Cuarteto de cuerdas n° 2  (1958), mientras  que la cita del folklore marca evidentemente el  primer estilo de Ginastera («nacionalismo ob- jetivo», 1935-1947), pero también es signifi- cativa en su estilo final, después de 1973. En  cuanto a la referencia de Ginastera a su pro- pia obra anterior, ésta se presenta como una  característica constante de la escritura de Gi- nastera, como una búsqueda de coherencia y  de economía en su personal estilo. Esta prác- tica de la cita, abierta a tres fuentes diferen- tes, apela a la competencia del oyente, quien  se ve guiado, por medio de los títulos y referen- cias provistos por Ginastera, hacia una recep- ción más completa de la obra.
Kallikrein-related peptidase 6 exacerbates disease in an autoimmune model of multiple sclerosis
Authors: Yoon Hyesook , Scarisbrick Isobel A.
Published: November 2016

Kallikrein-related peptidase 6 (Klk6) is elevated in the serum of multiple sclerosis (MS) patients and is hypothesized to participate in inflammatory and neuropathogenic aspects of the disease. To test this hypothesis, we investigated the impact of systemic administration of recombinant Klk6 on the development and progression of MOG35-55-induced experimental autoimmune encephalomyelitis (EAE). First, we determined that Klk6 expression is elevated in the spinal cord of mice with EAE at the peak of clinical disease and in immune cells upon priming with the disease-initiating peptide in vitro. Systemic administration of recombinant Klk6 to mice during the priming phase of disease resulted in an exacerbation of clinical symptoms, including earlier onset of disease and higher levels of spinal cord inflammation and pathology. Treatment of MOG35-55-primed immune cells with Klk6 in culture enhanced expression of pro-inflammatory cytokines, interferon-γ, tumor necrosis factor, and interleukin-17, while reducing anti-inflammatory cytokines interleukin-4 and interleukin-5. Together these findings provide evidence that elevations in systemic Klk6 can bias the immune system towards pro-inflammatory responses capable of exacerbating the development of neuroinflammation and paralytic neurological deficits. We suggest that Klk6 represents an important target for conditions in which pro-inflammatory responses play a critical role in disease development, including MS.

A necessary condition for the Smith equivalence of G-modules and its sufficiency
Authors: Morimoto Masaharu
Published: November 2016

Let G be a finite group. In this paper we give a new necessary condition for two real G-modules to be Smith equivalent if G has a normal Sylow 2-subgroup. We show that the condition is also sufficient under certain hypotheses. By results on the Smith equivalence obtained in this paper, the primary Smith sets are not subgroups of the real representation rings for various Oliver groups with normal Sylow 2-subgroups.
«Majestätische sittliche Gebäude». La critique de Nietzsche à la doctrine morale kantienne
Authors: Marton Scarlett
Published: November 2016

Cette étude se propose de jeter de la lumière sur la critique que Nietzsche adresse à la manière dont Kant institue sa doctrine morale. Prenant comme point de départ l’analyse des conceptions de la philosophie et du rôle que joue l’entreprise critique dans l’œuvre des deux philosophes, nous comptons examiner, tout d’abord, les divergences qui sont à la base de leurs procédés. Nous comptons ensuite évaluer dans quelle mesure Nietzsche comprend la résolution kantienne de la troisième antinomie de la «Dialectique Transcendantale» de la Critique de la raison pure. Nous espérons, enfin, élucider le but de la démarche nietzschéenne.
„Wachs in den Ohren“. Nietzsches Deutung der philosophischen Furcht vor der Musik in der Moderne
Authors: Branco Maria João Mayer
Published: November 2016

Im Beitrag soll der Sinn des Ausdrucks „Musik des Lebens“ in FW 372 geklärt werden. Die These Ist, dass Nietzsches Bezug von Musik und Philosophie in diesem Aphorismus nicht nur metaphorisch gemeint Ist und dass die Welse, in der moderne Philosophen mit Musik als Kunst umgehen, Konsequenzen für die moderne Konzeption des philosophischen Denkens hat. Mit Hilfe eines Vergleichs von FW 372 mit MA1217 legt der Beitrag erstens dar, dass Nietzsche eine Parallele zieht zwi­schen dem, was er den Prozess der Entsinnlichung nennt, der moderne Philosophen und moderne Musikhörer(innen) Jeweils ergriffen hat, und zweitens, dass Nietzsche diesen Prozess als gefährlich und bedrohlich sowohl für die Fähigkeit zu denken als auch für die Fähigkeit zu empfinden und Musik zu hören betrachtet.
Recording of high efficiency volume Bragg gratings in a photopolymer using diffraction from very weak pre-recorded gratings
Authors: Bade Dennis , Naydenova Izabela , Toal Vincent , Martin Suzanne
Published: November 2016

A two-step method of writing high diffraction efficiency holographic gratings in photopolymer using just one writing beam during the second step is discussed. The technique is based on the use of weak gratings (<1%) recorded during a first step which during the second step are illuminated with a single beam to form strong highly efficient holographic gratings. The weak grating provides a second interfering beam by diffracting a small portion of the illuminating light. Although effects such as beam pumping and twowave mixing arewell known in dynamic re-writable recording media such as photorefractives, the ability to write with one beam, or ‘pump’ gratings is not usually observed in photopolymer materials. Other methods of recording with a single beam have been reported, especially for data storage, but they use compact optical systems, polarization effects or lenticular devices to produce the required second beam. In this method, the second beam is produced within the photopolymer medium. Earlierwork by the authors reported increases in efficiency of weak photopolymer gratings illuminated by a single exposure beam, and more recently evidence was presented that diffraction at the weak pre-recorded grating was responsible for this effect. Here we demonstrate a strong dependence of the diffraction efficiency on grating thickness and show that the method allows the writing of high diffraction efficiency gratings in adverse conditions using a single beam. The possibility of angular multiplexing is also demonstrated. The technique may find application in writing information using pre-recorded weak holographic gratings and, potentially, in other data storage applications. In this paper it is shown that multiple new gratings can be writtenwhich are angularly separated and distinct from the pre-written grating and it is also possible to choose one grating from among a number of pre-written gratings and selectively amplify it without amplifying the others.
Refractory hypoglycemia in a patient with functional adrenal cortical carcinoma
Authors: Marchetti Katia Regina , Pereira Maria Adelaide Albergaria , Lichtenstein Arnaldo , Paiva Edison Ferreira
Published: November 2016

Adrenacarcinomas are rare, and hypoglycemic syndrome resulting from the secretion of insulin-like growth factor II (IGF-II) by these tumors have been described infrequently. This study describes the case of a young woman with severe persistent hypoglycemia and a large adrenal tumor and discusses the physiopathological mechanisms involved in hypoglycemia. The case is described as a 21-year-old woman who presented with 8 months of general symptoms and, in the preceding 3 months, with episodes of mental confusion and visual blurring secondary to hypoglycemia. A functional assessment of the adrenal cortex revealed ACTH-independent hypercortisolism and hyperandrogenism. Hypoglycemia, hypoinsulinemia, low C-peptide and no ketones were also detected. An evaluation of the GH–IGF axis revealed GH blockade (0.03; reference: up to 4.4 ng/mL), greatly reduced IGF-I levels (9.0 ng/mL; reference: 180–780 ng/mL), slightly reduced IGF-II levels (197 ng/mL; reference: 267–616 ng/mL) and an elevated IGF-II/IGF-I ratio (21.9; reference: ~3). CT scan revealed a large expansive mass in the right adrenal gland and pulmonary and liver metastases. During hospitalization, the patient experienced frequent difficult-to-control hypoglycemia and hypokalemia episodes. Octreotide was ineffective in controlling hypoglycemia. Due to unresectability, chemotherapy was tried, but after 3 months, the patient’s condition worsened and progressed to death. In conclusion, our patient presented with a functional adrenal cortical carcinoma, with hyperandrogenism associated with hypoinsulinemic hypoglycemia and blockage of the GH–IGF-I axis. Patient’s data suggested a diagnosis of hypoglycemia induced by an IGF-II or a large IGF-II-producing tumor (low levels of GH, greatly decreased IGF-I, slightly decreased IGF-II and an elevated IGF-II/IGF-I ratio).

Learning points:

Hypoglycemyndrome resulting from the secretion of insulin-like growth factor II (IGF-II) by adrenal tumors is a rare condition.

Hypoinsulinemic hypoglycemia associated with hyperandrogenism and blockage of the GH–IGF-I axis suggests hypoglycemia induced by an IGF-II or a large IGF-II-producing tumor.

Hypoglycemia in cases of NICTH should be treated with glucocorticoids, glucagon, somatostatin analogs and hGH.
LIBERALIZMO FILOSOFIJOS PARADOKSAI
Authors: Jokubaitis Alvydas
Published: November 2016

Straipsnyje siekiama įrodyti, kad po Johno Rawlso Politinio liberalizmo pasirodymo būtina naujai pažvelgti į liberalizmo filosofijos tapatumą. Liberalai neturi savarankiškos moralės ir politikos filosofijos. Jų filosofinis tapatumas grindžiamas ne pozityvia doktrina, bet oponentų kritika. Norint suprasti liberalizmo filosofiją, reikia išsiaiškinti jos santykį su neliberaliomis doktrinomis. Liberalų moralės ir politikos filosofija priklauso nuo neliberalių pažiūrų kritikos. Liberalizmo filosofija susiduria su neįveikiamais paradoksais: 1) politinis liberalizmas sulygina liberalus ir neliberalus, taip neleisdamas užtikrinti liberalizmo politinės filosofijos išskirtinumo, 2) iš liberalų pripažįstamo moralinio individualizmo nebūtinai seka liberalizmo moralės filosofija, 3) liberalų moralės filosofija pasižymi esminiais trūkumais, kuriuos įmanoma įveikti tik remiantis neliberaliomis moralės filosofijomis, 4) savo idėjinį tapatumą liberalai gali užtikrinti tik pasitelkdami ideologiją, o ne filosofiją. Tai, kas vadinama liberalizmo filosofija, yra pilietinės religijos variantas.
HEIDEGGERIO TECHNIKOS SAMPRATOS UŽUOMAZGOS ANKSTYVOSIOSE SENOVĖS GRAIKŲ INTERPRETACIJOSE
Authors: Mickevičius Tomas Nemunas
Published: November 2016

Straipsnyje parodoma ankstyvųjų Martino Heideggerio senovės graikų filosofijos interpretacijų svarba jo vėlesnei moderniosios technikos sampratai. Parodoma, pirma, kaip ankstyvųjų senovės graikų tekstų interpretacijose iškylanti pagamintos būties (Hergestelltsein) samprata su joje glūdinčiu pamatiniu graikų ontologijos orientyru į pastovią esamybę atsispindi vėlesniuose moderniosios techninės būties atverties apmąstymuose, tarpstančiuose po machinacijos (Machenschaft) ir vėliau – sąstato (Gestell) vardais. Antra, parodoma vieno iš pamatinių gaminančios Dasein veiklos (herstellende Verhalten) struktūrinių elementų – priežastingumo sampratos – svarba vėlgi vėlyvajai moderniosios technikos kaip būties atverties  interpretacijai. Ir trečia, parodoma, kaip ankstyvoji aristotelinės tέχνη kaip tiesos (ἀλήθεια) ar buvimo tiesoje (ἀληθεύειν) būdo samprata atsispindi moderniosios technikos kaip būties atverties būdo sampratoje.
PRIEVARTA KAIP MODERNYBĖS SĄLYGA: F. T. MARINETTI IR G. SIMMELIO ATVEJIS
Authors: Milerius Nerijus
Published: November 2016

Straipsnyje nagrinėjamas bendrosios kinematografinės prievartos sąlygos. Analizuojant šią problematiką, prievartos mene klausimas įprastai traktuojamas kaip klausimas apie meno autonomiją. Vis dėlto tokia prievartos statuso traktuotė yra ribota, nes ji ignoruoja faktą, kad modernybėje prievarta yra suvokiama ne vien kaip estetinis, bet ir kaip socialinis fenomenas. Siekiant išskleisti prievartos statuso modernybėje specifiką, interpretuojami du pavyzdžiai – Marinetti futurizmo manifestas ir Simmelio karo koncepcija. Marinetti postuluoja greitį, technologiją ir prievartą kaip sociumo pertvarkymo įrankius. Futurizmo manifeste aukštinamas ir karas kaip totalios prievartos forma. Prasidėjus Pirmajam pasauliniam karui, pats Marinetti įsitraukia į karo veiksmus, bet neišplėtoja nuoseklesnės karo koncepcijos. Tačiau tai, ko neįvykdė Marinetti, realizavo vokiečių sociologas Simmelis. Dar iki karo aprašęs sociumo krizę kaip atbukimo būseną, prasidėjus karui Simmelis ėmė jį traktuoti kaip atbukimo būklės įveikos viltį ir sociumo atsinaujinimo galimybę. Taigi, nepaisant Marinetti ir Simmelio nuostatų skirtumų, abu suteikia prievartai ir karui rezistencines ar net mesianistines prasmes. Straipsnyje argumentuojama, kad rezistencinė ir mesianistinė prievartos traktuotė yra neatskiriama nuo modernybės diskurso. Vis dėlto konstatuojama, kad tokia prievartos interpretacija neišvengiamai transformuojama post-industrinės visuomenės ir postmodernybės sąlygomis.

Los monstruos en la narrativa de Quiroga
Authors: Alvarado Vega Óscar G.
Published: November 2016

Los monstruos en Quiroga son producto de la febril creación de un escritor que construye, en el devenir de sus personajes, sometidos a un entorno que los asfixia, un mundo de desencanto, de derrota, de dolor, de muerte, de sufrimiento, de sed, de angustia. Leer la narrativa de Quiroga es encontrar a esos monstruos metafóricos que signan la vida difícil e ingrata en ocasiones de cada uno de ellos en ese mundo que los contiene, los limita y les recuerda, a cada instante, su propia pequeñez.

Conceptualizing Spirituality and Religion for Mental Health Practice: Perspectives of Consumers with Serious Mental Illness
Authors: Starnino Vincent R.
Published: November 2016

Studies show that a high percentage of people with serious mental illness (SMI) draw upon spirituality and religion, resulting in a call for practitioners to incorporate these as part of recovery-related services. A challenge is that there are differing definitions of spirituality and religion presented in the literature which could lead to confusion in practice settings. A qualitative study was conducted with 18 participants with SMI. Findings reveal that there are important nuances, and much overlap, related to how people with psychiatric disabilities define and conceptualize spirituality and religion. Three major conceptualizations of spirituality and religion are presented. Insights from this study are relevant to practitioners interested in incorporating spirituality as part of recovery-oriented practice.
Do We Really Know how Many Are Homeless?: An Analysis of the Point-In-Time Homelessness Count
Authors: Schneider Monika , Brisson Daniel , Burnes Donald
Published: November 2016

The Point-In-Time (PIT) count is currently the leading source of data on those experiencing homelessness in the United States. However, the PIT has been criticized for its lack of reliability, validity, and ability to capture an accurate numerical count of the homeless population. Additionally, many argue that annually a nontrivial amount of resources is spent on the PIT, yet the product from this count does not provide adequate information to address the issue of homelessness on a local, state, or national level. Findings from this comparative case study approach confirm that the cross-site methodology is inconsistent, and therefore the PIT yields inconsistent results. Implications and recommendations for local, state, and national service providers and policymakers are provided.
Microclimatology and ecophysiology of the urban vegetation of a city with tropical climate modified by altitude in Mexico
Authors: Barradas Víctor L. , Ruiz-Cordova Juan Pablo , Esperó-Rodríguez Manuel
Published: November 2016

Background. The urban area continues growing, and in most cases, the planning of green areas does not include in the species selection their physiological characteristics, which determine plant survival.

Question/Hypothesis. Stomatal conductance (gS) is a key variable that provides information on how the environment affects a plant physiology. Therefore it is important to inquire how gS is affected in an urban site.

Studied species/Data description. Data of environmental variables (photosynthetically active radiation, PAR; air temperature, T A; vapor pressure deficit, VPD ), leaf water potential, ?; and gS were collected in four species Ficus retusa , Fraxinus uhdei, Ligustrum lucidum and Quercus rugosa .

Study site and years of study. Two sites, in the center and in the rural area, were selected in Puebla, Mexico, during the wet and dry seasons (2012-2013).

Methods. Environmental variables, gS and ? were measured with a diffusion porometer and a pressure bomb through the day every two hours in apparently healthy leaves. Also an experiment under greenhouse conditions was performed.

Results. Maximum values of PAR, T A  and VPD were registered in the city center in the dry season, whereas maximum gS and ? were found in the rural area in the wet season. ? and gS were significantly higher in F. retusa followed by F. uhdei, whereas the lower values were observed in L. lucidum and Q. rugosa . All variables affected gS for all species.

Conclusions. The results demonstrate that it is possible to recommend Ficus retusa and Fraxinus uhdei as suitable species to ameliorate the urban environment.
Percepção e Elasticidade de Preço para Embalagens Sustentáveis de Alimentos
Authors: Kohmann Laura Moura , Medeiros Janine Fleith de , Vidor Gabriel , Ribeiro José Luis Duarte
Published: November 2016

As embalagens, principalmente de alimentos, representam grande parte dos resíduos sólidos gerados. Nesse sentido, o presente artigo buscou verificar, através de pesquisa descritiva, a intenção de compra de alimentos com embalagens sustentáveis, seja essa sustentabilidade obtida através de embalagens biodegradáveis, de reciclagem ou da aplicação da logística reversa. Resultados preliminares indicam que essa tendência é particularmente acentuada no caso de mulheres jovens e com nível elevado de escolaridade. A intenção de compra diminuiu em todos os grupos quando o alimento com embalagem sustentável apresentava custo acima do preço de mercado, revelando que a tolerância a acréscimos no preço é, em média, de 10%. O investimento de empresas em sustentabilidade, portanto, causa impactos positivos na decisão de compra do consumidor, principalmente nos que estão abaixo dos 50 anos.
Culture Economy for Economic Development: Assesments on Cultural Heritage in Turkey
Authors: Keser Hilal Yıldırır
Published: November 2016

Cultural economics can be grouped under four main headings: cultural heritage, arts, media (film, radio, television, music, journalism, and publishing) and creative services (design, advertising, new media, architecture, and software). These cultural goods and services that constitute the cultural economy interact with other industries. This interaction has an impact on the development process by creating added value for the economy through the multiplier effect. The cultural industries that are also referred to as creative industries tend to have a significant economic impact, mainly in terms of providing employment and increasing exports. In contrast, tourism, textiles, jewellery, toys, and many other suppliers ensure the development of these industries by creating indirect economic impacts. In this context, firstly cultural economics and its scope will be discussed, and its relationship with economic development will be explained. Next, referring to examples of tangible and intangible cultural heritage, the impact of cultural economics on the economic development of Turkey will be explored, specifically with regards to the Cappadocia region.

The present study aims to investigate whether the psychometric results proposed by (Sanjuan, Perez, & Bermúdez, 2000) for general selfefficacy scale replicate. The total sample was of 282 subjects; 142 women and 140 men, college students from the city of La Paz Baja California Sur Mexico, with an mean age of 20.3 years (SD = 1.6) for women and 20.9 years (SD = 1.6) for men. The factorial structure of the questionnaire was analyzed by confirmatory factor analysis. The analysis shows a feasible and appropriate factor structure. The structure of a one factor, based on statistical and substantive criteria, has shown adequate fit indicators of reliability and validity. In addition, the factor obtained a Cronbach´s alpha coefficient of .914. Future research should replicate these findings in larger samples.
Servqual Model as Performance Evaluation Instrument for Small and Medium Sized Enterprises (SME): Evidence From Customers in Nigeria
Authors: Obioma,H Onyeaghala,
Published: November 2016

It is the intention of this study to ascertain if SERVQUAL model can serve as an instrument for measuring performance of small and medium scale enterprises in Nigeria. The study adopted the Kano model as the theoretical framework. Empirical works on service quality and customer satisfaction were reviewed. Survey research design was adopted and conducted with the use of structured questionnaire designed in a 5 point likert scale format ranging from strongly agree, agree, strongly disagree, disagree and undecided. Twelve (12) small and medium scale enterprises operating in six geo-political zones of Nigeria were judgmentally selected, from where a sample of 60 was drawn using Taro Yamane formula. The questionnaire was validated and its reliability established. Data presentation and analysis was carried out using tables and simple percentages. Chi-square statistic; a nonparametric technique was employed in the test of the three hypotheses formulated to guide the study. This led to rejection of the three null hypotheses indicating that: Service quality dimensions has relationship with performance of small and medium scale enterprises; tangibility, reliability, responsiveness, assurance and empathy services can be used to measure performance of small and medium scale enterprises. This justifies that SERVQUAL dimensions; tangibility, reliability, responsiveness, assurance and empathy are indicators of customer satisfaction, implying that they can be employed as performance evaluation tools for small and medium scale enterprises. It is recommended that small and medium scale enterprises should direct their operations in line with SERVQUAL dimensions, if they want to achieve customer satisfaction and business performance.

Sentidos (tra)vestidos: a individuação e a constituição do sujeito travesti pelo Estado
Authors: Pereira Lidia Noronha , Silva Telma Domingues da
Published: November 2016

Filiados ao campo teórico da Análise de Discurso, procuramos discutir nesse trabalho como o sujeito travesti é significado e individuado pelo Estado no Brasil. Portanto, analisamos dois cartazes confeccionados e distribuídos pelo Ministério da Saúde, que compõem a campanha de combate à AIDS. Nosso objetivo foi compreender como o sujeito travesti é discursivamente inscrito em tais cartazes, de circulação nacional e pública, marcados por um gesto administrativo. Os logotipos de esferas de governo que compõem os cartazes demarcam um território, ou seja, um espaço histórico, simbólico e geograficamente institucionalizado. Além disso, nessa posição do Estado, o sujeito travesti é significado de uma certa maneira, uma vez que é convocado por esta campanha também de uma certa maneira. A fim de prosseguirmos com essa análise, foi considerado o corpo do sujeito travesti enquanto forma material (Orlandi, 2012), reconhecendo a sua inscrição no simbólico e que esta inscrição é sustentada pelos discursos específicos. De acordo com nosso ponto de vista, não poderíamos lidar com os cartazes como se eles meramente representaram imagens impressas em formato cartaz. Ao contrário, a nossa análise permitiu apontar efeitos de sentido produzidos para o corpo travesti por um gesto interpretativo, e que esses efeitos significam processos de identificação do sujeito travesti. Há, além disso, os resultados dessa análise que apontam para a necessidade de romper o “já-dito” em relação ao sujeito travesti.

Linhas, redes e filamentos: no fio do discurso da cidade
Authors: Dias Cristiane
Published: November 2016

Esse artigo tem como objetivo mostrar, a partir do modo como os dispositivos tecnológicos estão incorporados à cidade, como as formas de circulação ou interdição à mobilidade, ressignificam o espaço urbano e aquilo que lhe é próprio: os sujeitos e os movimentos. Como a conectividade passa a ter papel fundamental na forma de organização social dos sujeitos. Forma de organização que tema colaboratividade como característica. Essas questões permeiam a escrita desse artigo sob a perspectiva teórica e analítica da Análise de Discurso, que considera o confronto entre o simbólico e o político.
« Tu sais que tu viens de [Ville] quand… » : Communauté urbaine en ligne
Authors: Goudet Laura Gabrielle
Published: November 2016

Dans cet article, je propose de montrer le rapport entre le discours sur des communautés virtuelles et le discours sur la ville, dans un corpus Facebook de pages dont le titre comporte le patron itératif « tu sais que tu viens de [x] quand ». Ces pages s’insèrent dans une représentation numériquée de la ville. Le symbolisme urbain passe par les illustrations, qui représentent des éléments identitaires forts, et les chartes des pages incitent les utilisateurs à participer. Les discours sont mélioratifs, et la fierté côtoie la nostalgie des membres qui n’y habitent plus. Les récits urbains génèrent la collaboration entre les abonnés. La ville s’insère dans sa culture régionale, grâce aux langues régionales. La nourriture locale devient une passerelle d’évocation d’expériences communes.
Cidade e tecnologia: corpo e afeto no laço geossocial
Authors: Barbai Marcos Aurélio
Published: November 2016

O objetivo deste artigo é o de refletir sobre os processos de significação e o laço social amoroso no mundo contemporâneo. Para isto, escolhi como material de análise os perfis de alguns usuários do aplicativo para smartphones Scruff, que se propõe como uma rede social de encontros amorosos para homens gays. Interessa-me, no trabalho com este aplicativo, pensar a entrada no sujeito na ordem de um discurso que pressupõe a sua enunciação. Trabalho com a hipótese de que o laço amoroso em tempos de aplicativo de celular, através da ferramenta dageolocalização, produz uma sincronia entre corpo e presença subjetiva. Denomino esta sincronia através do conceito de georefêrencia, o ato que entrelaça corpo, presença, conexão na busca do bom objeto amoroso.
Um corpo em jogo: discurso, imersão e tecnologia

Com o objetivo de pôr em discussão os processos de significação na contemporaneidade, que se constituem afetados pela tecnologia e que incidem sobre a formação social, produzindo efeitos de sentido e de sujeito, proponho apresentar uma reflexão sobre a relação entre corpo, imagem e tecnologia, com base nos pressupostos da Análise de Discurso, e em face dos conceitos de imersão, interatividade e imagem de síntese (ROBIN, 2003; PARENTE, 1993). Busco compreender de que maneira o corpo, enquanto materialidade específica do sujeito (ORLANDI, 2012), está investido em um processo discursivo que pressupõe a relação com a tecnologia e o espaço. Tomo como lugar de observação o universo dos jogos eletrônicos, e analiso como determinadas relações sociais se significam e são significadas aí, a partir do modo como memória e imaginário social se confrontam e atuam nas discursividades desse universo.
Empirical Prediction of Turnovers in NFL Football
Authors: Bock Joel
Published: November 2016

Turnovers in the National Football League (NFL) occur whenever a team loses possession of the ball due to a fumble, or an interception. Turnovers disrupt momentum of the offensive team, and represent lost opportunities to advance downfield and score. Teams with a positive differential turnover margin in a given game win $70\%$ of the time. Turnovers are statistically rare events, occurring apparently randomly. These characteristics make them difficult to predict. This investigation advances the hypothesis that turnovers are predictable in NFL football. Machine learning models are developed to learn the concept: At any point within a football game, what is the likelihood that a turnover will be observed on the next play from scrimmage? Results presented suggest evidence to support the working hypothesis. Under certain conditions, both fumbles and interceptions can be anticipated at low false discovery rates (less than $15\%$). This approach may be useful to inform in-game strategies to mitigate the negative consequences of turnovers by an offensive team, or to maximize their probability by a defensive squad.

Molding technology is widely used to manufacture optical components because of its high efficiency. Along with the quick development of miniaturization in industry, the detrimental effects of previously negligible burrs and defects on mold surfaces have become significant to the performance of components, so these problems should be minimized. In this study, a laser assisted micromachining method was developed to solve this problem during the fabrication of periodic microstructures on a molding material of electroless nickel-phosphorus (NiP) plating. The transient temperature distributions of the workpiece under laser irradiation and the change in the maximum shear stress during the laser assisted micromachining process were simulated to set appropriate experimental conditions. Then, periodic micropyramid structures were fabricated by both conventional cutting and the laser assisted cutting processes. Results show that defects largely decreased on machined structures with the assistance of laser irradiation. The decrease in specific cutting force and the change of chips’ morphology were also utilized to analyze the reasons for this improvement.

This article illustrates an advanced approach in force measurement standards. It gives a spot on the design, manufacturing and evaluation for a prototype of force transducer with multi-capacity. This prototype has three adjustable capacities (5kN, 10kN and 15kN) and works on compression mode. The introduced design offers a comparative load cell looking forward to replace three force transducers with the same capacities (5kN, 10kN and 15kN) which are commercially available. Experimental results reveal satisfactory agreements with that calculated with analytical method and results simulated using finite element techniques. The detailed metrological characteristics of this multi-capacity load cell will be published later.
Anterior Cervical Discectomy and Fusion

Anterior cervical discectomy and fusion can be performed for a variety of pathologies but is most commonly used for the treatment of cervical radiculopathy or myelopathy. The procedure involves an anterior decompression of the disc space followed by interbody grafting and fusion. Supplemental anterior plating is commonly performed, and in certain circumstances, posterior instrumentation may provide additional fixation.

The procedure includes the following steps: (1) The use of an anterior approach to the cervical spine, most commonly the Smith-Robinson approach medial to the sternocleidomastoid muscle and the carotid sheath. (2) Confirmation of the proper spinal level. (3) Elevation of the longus colli muscle, which acts as a cuff for the placement of retractors. (4) Removal of the involved disc and decompression of the spinal cord and nerve roots. This is facilitated by disc space distraction, most commonly via distraction pins. Osteophytes along the floor of the spinal canal impinging on the spinal cord are removed with a burr. Soft disc and anular material are also removed, usually with curets and rongeurs. Uncovertebral osteophyte resection and foraminotomies are completed to decompress the exiting nerve roots. (5) Carpentry and decortication of the end plates in preparation for fusion. (6) Sizing of the disc space followed by insertion of an interbody graft. (7) Anterior fixation, most commonly via application of a plate-and-screw construct. (8) Hemostasis and closure.
Upstream Opportunities in North Africa Depend on Advanced Technical Knowledge

Conference review - The SPE North Africa Technical Conference and Exhibition

The SPE North Africa Technical Conference and Exhibition held in Cairo in September highlighted the upstream sector with a focus on Egypt and the opportunities offered in the region, despite its economic hardships and geopolitical risks.

Delivering the keynote speech on behalf of the petroleum minister, Sherif Ismail, who was appointed as Egypt’s prime minister one week before the event, Sherif Sousa said that North Africa offers many opportunities in the upstream sector. Sousa is the first undersecretary of gas affairs at Egypt’s Petroleum and Mineral Resources Ministry.

“There are as many opportunities today as there ever were, but they are different and lie in more harsh environments requiring advanced technologies and greater investments. A clear example is the recent Zohr discovery achieved by Eni,” he said. “Zohr is the largest gas discovery ever made in Egypt and in the Mediterranean Sea.”

The region is also facing rising costs. “Exploration and production [E&P] costs in different regions are escalating dramatically, putting more pressure on upstream activities, where existing and future oil and gas opportunities cannot be explored without applying state-of-the-art-technologies,” he said.

Innovation is required for tapping the region’s vast resources. “We can also expect further innovations to reduce the escalating costs of exploration and production, unlock additional resources, and increase supplies,” Sousa said.

Ahmed El-Banbi, program chairman and a professor at Cairo University, said that the oil price downturn may not continue for a long time, and the industry will emerge for the better and more efficient. “We have done this before, and we will do it again. So, get ready for the industry when it bounces back,” he said.

Osama El-Bakly, chairman of Agiba Petroleum, said that soaring domestic consumption has led Egyptian General Petroleum Corp. (EGPC) to speed up its development plans. He spoke on behalf of Tarek El Molla, conference chairman and the chief executive officer (CEO) of EGPC.
Optimized Design of Autonomous Inflow-Control Devices for Gas and Water Coning

Published: November 2016

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 173203, “Optimized Design of Autonomous Inflow-Control Devices for Gas and Water Coning,” by Terry W. Stone, Terje Moen, David A. Edwards, Alexander Shadchnev, and Kashif Rashid, Schlumberger, and Geir Frode Kvilaas and Kjell Christoffersen, Det Norske Oljeselskap, prepared for the 2015 SPE Reservoir Simulation Symposium, Houston, 23–25 February. The paper has not been peer reviewed.

Several designs for autonomous inflow-control devices (AICDs) are available. One forces inflowing fluids to enter gates, depending on inertial and viscous forces of the various fluids. Another is an autonomous valve in the shape of a free-floating disk that restricts the flow rate of low-viscosity fluids and is primarily used to choke gas and water inflow. Recently, a device with water-swellable rubber inside the nozzle has been proposed, but it is not yet commercially available. The comparative properties and abilities of these designs are the focus of this paper.

Well Model, Reservoir Simulator, and Optimizer

The well model used in this work is part of a next-generation parallel commercial reservoir simulator and features a flexible multisegmented well topology, enhanced robustness for difficult problems, and extensive well-model options. It forms part of a scalable parallel commercial reservoir simulator.

Optimizations carried out in this work used an optimizer developed to alleviate the computational cost in an optimization study where simulation-based objective functions are expensive to evaluate. When compared with several other commonly used optimizers, it was demonstrated that this optimizer outperformed others significantly.

Modeling Inflow-Control Devices (ICDs)

Various ICD designs include those with nozzle orifices, tubes, and helices. Unlike ICDs, AICDs may or may not have moving parts but they can change or modify their state in response to inflow. Design of the AICD determines the particular unwanted fluids that are delayed. There are a number of types available commercially, including a floating flapper, an oil- selector valve, an autonomous inflow-control valve, the rate-controlled-production (RCP) valve, and a fluidic diode valve. Another design recently proposed is based on inclusion of water-swellable rubber within the nozzle, but this is not yet commercially available. Both ICDs and AICDs are often deployed in a compartment whose edges are sealed with a packer, and are placed in the tubing wall between an annulus and main production stream.
A Study of Wettability-Alteration Methods With Nanomaterials Application

Published: November 2016

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 173884, “A Review Study of Wettability-Alteration Methods With Regard to Nanomaterials Application,” by Milad Jokari Sheshdeh, Technical University of Clausthal, prepared for the 2015 SPE Bergen One Day Seminar, Bergen, Norway, 22 April. The paper has not been peer reviewed.

The use of nanomaterials for alteration of wettability is a method that has grown in prominence after the development of techniques for synthesizing nanosized particles in the late 1980s. In this paper, after a review of the fundamentals of wettability alteration, a discussion of nanomaterials used for wettability alteration is provided. Among these nanomaterials, nanoparticles of silica and polysilicone indicate better results in terms of efficiency on incremental oil recovery in waterflooding.

Introduction

Wettability is the tendency of a fluid to spread over a specific surface and is relative to other existent fluids in that system and is defined by the contact angle of a droplet of the fluid and the surface. It is a result of adhesion forces between the fluid and the minerals of the rock. The wettability of a rock ranges from strongly water-wet to strongly oil-wet and is a result of brine/oil/rock interactions in a reservoir. There are different types of rocks on the basis of these interactions and wettabilities:

If no, or equal, tendency is shown from oil or brine to spread over the surface of the rock, the system is said to have neutral wettability or intermediate wettability.

Because different mineralogies coexist in an oil reservoir, different wettabilities are also expected. If this variety in the reservoir is not negligible, then, in different parts of the reservoir, different chemical interactions between fluids and rocks are observed and, consequently, some areas of the reservoir indicate strongly water-wet behavior whereas some other areas indicate strongly oil-wet behavior. This heterogeneous wettability behavior is known as fractional wettability.

In some cases, the smaller pores are occupied by water and can be considered water-wet, while larger pores are captured by oil. This type of wettability distribution is known as mixed wettability, in which the residual oil saturation is low because the oil is displaced more easily from larger pores.

The solid/fluid and fluid/fluid surface energies are governed by the chemical compositions of the fluid and rock. In other words, the mineralogy of a rock and chemical properties of the fluid influence the relative adhesive tensions and, consequently, wettability.

The most common methods for wettability measurements, discussed in detail in the complete paper, include the following:

Amott wettability index

US Bureau of Mines (USBM) wettability index

Combined Amott-USBM wettability test

Contact-angle methods
