Published: November 2017

O morango é um fruto com rápida perecibilidade, mesmo assim, há poucos trabalhos na literatura a respeito do uso de produtos para aumentar a sua conservação pós-colheita. Assim, o estudo teve o objetivo de avaliar a qualidade e a conservação de frutos de duas cultivares de morango, submetido ao 1-Metilciclopropeno (1-MCP), armazenados sob temperatura refrigerada. Foram avaliadas as cultivares Albion e San Andreas. Os frutos foram colocados em câmaras fechadas e submetidos ao tratamento com 100 nL L-¹ de 1-MCP pelo período de duas horas. Após o período de aplicação, os frutos foram embalados e armazenados sob temperatura de 4º C ± 1ºC e umidade relativa de 90% ± 5% por 24 dias. O delineamento experimental foi inteiramente casualizado com três repetições e oito frutos por parcela, sendo adotado o esquema fatorial 13 x 2 x 2 (13 tempos de avaliação - dias 0; 2; 4; 6; 8; 10; 12; 14; 16; 18; 20; 22 e 24; duas cultivares, Albion e San Andreas; e dois tratamentos, tratados com 1-MCP e controle. Os frutos foram avaliados quanto à firmeza, perda de massa, pH, sólidos solúveis, acidez titulável, ácido ascórbico, antocianinas totais e carotenoides totais. O uso do 1-MCP não foi eficiente em alterar as características de qualidade avaliadas, pois estas evoluíram normalmente, em ambas as cultivares.
Ultrasound-Assisted Enzymatic Synthesis of Poly-ε-Caprolactone: Kinetic Behavior and ReactorDesign

Published: November 2017

Abstract
Lipase-mediated, ultrasound-assisted synthesis of poly-ε-caprolactone was investigated. It was found that ultrasound irradiation helped to improve the rate constant of poly-ε-caprolactone chain propagation (kp) at high initial monomer (ε-caprolactone) concentration. The enhancement of kp ranged from 34% to 46% at 22.5–18.0 M initial monomer concentration, respectively. In a system proned to time-dependent mass-transfer limitation due to polymer chain extension, the acoustic effects could have also allowed the reaction to continue longer compared to non-sonicated process until it became impossible at highly elevated reaction mixture viscosity(>2,000 times increase from initial viscosity). Consequently, it also helped to improve monomer conversion. In a continuous flow polymerization system, a plug flow reactor system is recommended due to its lowest volume for maximum conversion compared to a continuously stirred tank reactor system.
The Right Not to Have Rights: Posted Worker Acquiescence and the European Union Labor Rights Framework
Authors: Lillie Nathan 
Published: November 2017

AbstractThe emergence of the European Union citizenship agenda has mainly taken place along the evolution of mobility rights, with the goal of creating a pan-European labor market. Mobility undermines the nationally embedded notion of industrial citizenship. Industrial citizenship protects workers’ rights and secures their participation in national political systems. The Europeanization of labor markets severs the relationship between state, territory and citizen on which industrial citizenship has been built, undermining worker collectivism and access to representation. This is legitimated in terms of building market-citizenship, i.e., enabling mobile workers as market actors. However, the way mobility is regulated in the EU has the purpose and effect of weakening collective labor institutions, which also undermines workers’ ability to act as autonomous market actors. The same factors which undermine the industrial citizenship of mobile workers also prevent them from being effective free market agents: i.e., they can neither negotiate nor enforce individual contracts effectively in the face of systematic employer fraud and wage theft. The “Arendtian dilemma” of the “right to have rights” — a dilemma that derives from the claim that rights depend on the existence of a political community, which until now is the territorially exclusive nation-state, rather than universal personhood — emerges as industrial citizenship is internationalized. By disembeddeding workers from host-country industrial relations systems, EU regulation provides the social context in which workers’ rights become alienable.
Unionizing Subcontracted Labor
Authors: Shamir Hila 
Published: November 2017

Subcontracting — the practice of using intermediaries to contract workers, whether through temp agencies, manpower agencies, franchise, or other multilayered contracting — is an increasingly popular pattern of employment worldwide. Whether justified from a business perspective or not, subcontracting has dire implications for workers’ rights: it insulates the beneficiary of their labor from direct legal obligations to the workers’ wages and working conditions and drastically reduces their ability to effectively unionize. This Article explores the impact of subcontracting on unionization of subcontracted labor. It argues that labor law in most postindustrial developing economies is structured around the Fordist model of production and employment and therefore provides insufficient protections to workers whose employment arrangements deviate from that model.The Article maps the various hurdles subcontracting poses to unionization. It identifies three main challenges to the basic assumptions that animate traditional labor law: first, that a union has leverage and significant bargaining power vis-à-vis an employer; second, that the union and the employer are repeat players in negotiations, and that accordingly the labor contract is a relational contract in which both parties consider the short and the long term in their calculations; and third, that the bargaining unit represented by the union is relatively easily discernable and relatively stable. The Article argues that subcontracting disrupts all of these assumptions. Accordingly, in order to remain relevant to subcontracted workers, labor law requires adaptations. The Article sketches a preliminary list of existing and potential legal responses to subcontracting that better guarantee subcontracted workers’ rights to unionize. Its main suggestion is to move away from a bilateral towards a multilateral structure of collective agreement bargaining in subcontracting situations. Finally, the Article questions whether law can provide a once-and-for-all solution to the problems posed by subcontracting, and explores the dynamic role of law and unionizing in this context.
In the Time of Plastic Representation
Authors: Warner Kristen J. 
Published: November 2017

To many men and women of color, as well as many white women, meaningful diversity occurs when the actual presence of different-looking bodies appears on screen. For them, this diversity serves as an indicator of progress as well as an aspirational frame for younger generations who are told that the visual signifiers they can identify with carry a great amount of symbolic weight. As a consequence, the degree of diversity became synonymous with the quantity of difference rather than with the dimensionality of those performances. Moreover, a paradoxical condition emerges whereby people of color have become more media savvy yet are still, if not more, reliant on overdetermined and overly reductive notions of so-called “positive” and “negative” representation. Such measures yield a set of dueling consequences: first, that any representation that includes a person of color is automatically a sign of success and progress; second, that such paltry gains generate an easy workaround for the executive suites whereby hiring racially diverse actors becomes an easy substitute for developing new complex characters. The results of such choices can feel—in an affective sense—artificial, or more to the point, like plastic.
Black representation, as it's been understood in a popular sense, has been dominated by the circulation of mediated imagery yielding deleterious effects for the groups depicted. The fear of the effects of such “poor” representation has resulted in a set of binary, nonscientific, underdeveloped metrics—positive and negative—that constitute a nebulous catch-all system wherein the characteristics that define each pole on the spectrum shift depending on the era and the expectations of the audience. What marks a representation as “positive” or “negative”? Responses are often aligned with class (good job, education, community minded), behavior (hypersexual, well-spoken, “woke”), or with characterizations of character that either successfully assimilate into normative culture or fail to do so. However, such a scale oversimplifies the complexities of black identity that require audiences, pop culture critics, and scholars to invest in screen characters through experiencing nuances developed over time and ironically reinforces the stereotypes that operate as industry shorthand. The rationale for solely demanding plastic representation is understandable as a sanity-preserving tactic that can also build esteem and confidence, but it is not nearly enough. Meaningful, resonant diversity is a more difficult, underdeveloped approach that requires all stakeholders to think harder about what on-screen difference looks and feels like. But if representation truly matters, then it is an approach worthy of pursuit.
Death Grips
Authors: Gillespie Michael Boyce 
Published: November 2017

Black death in contemporary cinema requires understanding how film blackness always means provoking new entangled measures of the aesthetic, political, social, and cultural capacities of black visual and expressive culture. As a result, the critical consequence of film blackness always entails issues of affect, narrativity, visual historiography, and genre/modalities. Black death, then, signifies both the violent injustice of African American deaths and the rendering of death in cinema. Three short films by black women filmmakers represent an ever-growing archive of recent works that merit critical attention as they advance cinematic practices that point to new political philosophies and circuits of knowledge related to black death and film form. Taken together as a “cinema in the wake,” the three—Leila Weefur's Dead Nigga BLVD (2015), Frances Bodomo's Everybody Dies! (2016), and A. Sayeeda Clarke's White (2011)—pose a range of formal propositions about black death that include animation, the racial grotesque, and speculative fiction.
With distinct and compelling conceptions of black death, these three short films are deeply located in their contemporary American moment. Thinking with these films involves thinking through performing objects, the racial grotesque, and the futurity of social deletion. Together these films exquisitely suspend, disrupt, and disturb constituting distinct visual historiographies and strategies. As cinema in the wake, these films are stirred by incitements of film form, materiality, temporality, and conceptions of black being. But, more importantly, to think through black death across the formal experimentation and critical capacities of this work is to contend with an enduring urgency, the precarity of black life.
A tetrahidrobiopterin (BH4)-deficientia diagnosztikája és kezelése
Authors: Bókay János 
Published: November 2017

Abstract: Since the initial breaking discovery of Følling that the severe neurological consequences of phenylketonuria could be prevented by use of low phenylalanine (Phe) diet, it has been shortly recognised that defective phenylalanine metabolism may also arise from the deficiency of tetrahydrobiopterin (BH4) cofactor, required for phenylalanine-hydroxylase activity. Furthermore, as BH4 is in Phe metabolism, it is also a cofactor for the activities of tyrosine hydroxylase and tryptophane hydroxylase, enzymes required for the synthesis of catecholamines and serotonin neurotransmitters. Besides hyperphenylalaninemia in patients with tetrahydrobiopterin deficiencies, dopamine and serotonin deficiencies, with different disorders of the central nervous system also develop. Mild form of tetrahydrobiopterin deficiency is rare, most of the patients have severe neurological abnormalities including progressive mental retardation if not treated properly. Early diagnosis and treatment are essential and can improve the clinical course and prognosis. Orv Hetil. 2017; 158(48): 1897–1902.
Tormenta em Mar de Lápides: estética, memória e narração no Monumento aos Judeus Assassinados da Europa
Authors: Velasco Fernando , Melchior Laila 
Published: November 2017

Este artigo traz para a discussão algumas reflexões sobre o “Monumento aos Judeus Assassinados da Europa”, na cidade de Berlim, em perspectiva ético-estética, a partir de uma abordagem multidisciplinar, em que interagem discussões próprias aos campos das artes, da literatura e da história. Para tanto, são propostas relações entre particularidades formais do “Memorial aos Judeus”, em sua presença concreta como monumento, e debates sobre a possibilidade de uma memória de Auschwitz em que se adensam o compromisso ético da lembrança de um passado de morte e o apelo à transformação da vida no presente. Elabora-se, ainda, a possibilidade de uma narração que, no lugar de opor a concretude abstrata do “memorial” como obra de arte ao significado histórico de sua metáfora como cemitério, ganha forma exatamente no encontro entre presença e imagem, entre matéria e memória. À guisa de conclusão, introduz-se, como chave analítica, a figura singular de um narrador que, diante do “Monumento aos Judeus Assassinados da Europa”, é capaz de recolher os rastros de um passado que contém em si mesmo seu futuro, no instante evanescente de um esbarrão entre vida e história.
Celiac Disease or Gluten Sensitivity? A Mini Update Review
Authors: Papandreou Dimitrios 
Published: November 2017

Celiac disease is described when some people have with foods that contain gluten. Gluten is a type of protein. It's found in the grains wheat, barley and rye. It has antigenic properties and usually triggers an immune response. On the other hand, gluten sensitivity or intolerance is a similar condition that causes a person to react to gluten found in the above food items described.Even though the clinical symptoms are similar to both conditions, the pathology, diagnosis and treatment is different, thus it is very important to get the correct diagnosis. The purpose of this mini review is to compare the main aspects of these two conditions.
A New Test for Independence in 2×2 Contingency Tables
Authors: Sulewski Piotr 
Published: November 2017

In statistical literature there exist many tests to reveal the independence of two qualitative variables in two‑way contingency tables (CTs), in particular in 2×2 CTs. In this paper four independence tests were compared. These are: the chi‑square test, being the most popular type of power divergence statistics; the modular test and the d‑square test, which is a modification of the Pearson’s test; the logarithmic minimum test which is a new proposal. Critical values for the tests listed above were determined with the Monte Carlo method. In order to compare the tests, the measure of untruthfulness of H0 was proposed and the power of the tests was calculated.

Borehole Controlled–Source Electromagnetics for Hydrocarbon–Saturation Monitoring in the Bockstedt Oil Field, Onshore Northwest Germany
Authors: Tietze K.. , Ritter O.. , Patzer C.. , Veeken P.. , Verboom B.. 
Published: November 2017

Summary
Production from oil fields requires the monitoring of hydrocarbon saturation in the reservoir. In the Bockstedt oil field there exists a substantial difference in resistivity between an oil-filled (approximately 100–16 Ω·m) and a brine-filled (0.6 Ω·m) reservoir. Controlled-source electromagnetics (CSEM) is chosen to test whether sufficient resistivity differences can be observed by means of surface measurements. The target is a Lower Cretaceous clastic interval at an approximate depth of 1200 m.
Forward modeling demonstrates that the expected resistivity changes at reservoir level cannot be resolved with a survey setup of only surface electrical sources and sensors. Therefore a borehole-to-surface technique has been developed, whereby the metal casing of an abandoned production well serves as an input electrode. CSEM surveys were acquired in 2014 and 2015 as a time-lapse baseline and monitor for both horizontal electric (Ex and Ey) components. A four-transmitter and 25-receiver configuration was deployed for these surveys. Forward modeling indicates that induction effects from metal objects, such as casings of production wells, cannot be ignored in the electromagnetics (EM) modeling. A shallow observation well was drilled in 2015 to make the collection of vertical electric field (Ez) data sets possible. A new downhole sensor was developed for this purpose. Numerical simulations suggest Ez data are more sensitive to the anticipated resistivity changes in the reservoir. Because Ez is two orders of magnitude smaller than the horizontal components, verticality is of great importance to avoid masking the Ez signal by interference from unwanted horizontal components.
Similar acquisition parameters are adopted for 2014 baseline and 2015 monitor surveys to facilitate the comparisons. The repeatability is good, generating comparable response functions. A new, computationally efficient approach considers the effect of the metal casings, and is implemented in the 3D modeling and inversion codes. Preliminary resistivity models obtained from 3D CSEM inversion explain the observed data, and are in agreement with results from a 3D-seismic survey and resistivity logs in the calibration wells. Incorporation of the metal casings in the EM-modeling scheme increases the lateral continuity of inverted resistivity bodies.
In November 2016, a new time-lapse acquisition campaign was undertaken to collect a second Ex/Ey monitor and the first monitor survey for the Ez component.
Volumetric and Viscosity Studies of Gas and Oil from the Santa Maria Valley Field

Published: November 2017

Abstract
Determinations were made of the viscosity of the liquid phase and of the volume of mixtures of gas and liquid samples from the production trap of a well in the Santa Maria Valley field in California. Measurements were made at 100°, 190°, and 250°F. and at pressures up to 5000 lb. per square inch.

Introduction
In recent years a reasonable quantity of experimental data has been accumulated concerning the volumetric behavior and the viscosity of hydrocarbon systems. One of the main objectives for such work is the attempt to predict the properties of naturally occurring hydrocarbon mixtures under the conditions encountered in nature. At the present time the volumetric behavior of homogeneous hydrocarbon mixtures can be predicted with reasonable accuracy within certain ranges of composition over a relatively wide range of temperature and pressure. Heterogeneous systems offer a more difficult problem. The viscosity of both simple and complex hydrocarbon mixtures has been investigated in some detail. Nevertheless, information regarding this property is as yet insufficient to permit dependable forecasts for many cases of practical interest. For this reason a study of the volumetric behavior and the viscosity of the liquid phase of several mixtures of oil and gas from the Santa Maria Valley field was carried out.
