Analysis of injection molding for computer cooling fans by Taguchi method and grey relational analysis
Authors: Lo Chi-Hung
Published: March 2017

Various factors affect the quality of a plastic product during the injection
molding process. In this study, the quality engineering planning method,
Taguchi Method, and grey relational analysis were used in this study to
determine these factors and the Moldflow Plastics Insight (MPI) was used to
conduct the moldflow analysis. By varying different types of operating
conditions, the results obtained from the experiments were analyzed so as to
verify the influence of each factor on the quality of the final product. The
optimal processing parameters which can reduce the mold tryout time and the
analysis cost were then determined. The plastic impeller of a computer
cooling fan is selected as the case study and the goal is to resolve the
warping problems. The deviations in the shear stress distribution as obtained
by varying the S/N ratio of variance factors during the experiments are in
agreement with the results of analyzing the grey information relational
degrees. The most influential factor is the mold temperature, followed
sequentially by the fill time, fill pressure, and melt temperature.
The influence of user community’s innovative climate on user knowledge sharing willingness

Published: March 2017

This research combines the conception of Innovative Climate and Users
community. At this basis, we construct a model to explain how Innovative
Climate generated from community, supervisors do and users affect users
anthropology knowledge sharing intention. In this way, we construct a SEM and
verify it with 245 samples. The conclusion shows that Innovative Climate has
positive impacts on users knowledge sharing intention, but Innovative Climate
generated from different sources has different impact path. Subjective Norm
has a full mediation effect between Community Support and users anthropology
knowledge sharing intention, Supervisor Support and users anthropology
knowledge sharing intention. Nonetheless, effects between Subjective Norm and
User Support were partial mediated by Innovative Climate.
On the impact of various formulations of the boundary condition within numerical option valuation by DG method
Authors: Hozman Jiří , Tichý Tomás
Published: March 2017

Options, a crucial type of financial instrument, are very challenging as
concerns both, the application and valuation. A key property of (exotic)
options is to provide a tool to manage the market risk coming from everyday
innovations at the market. Due to the complexity of underlying processes
and/or payoff functions valuation via numerical methods is often inevitable.
The flexibility in terms of model assumptions often brings high time costs so
that it can be useful to reduce the space on which the computation is
executed in order to keep both the computation time and calculation error at
acceptable levels. Efficient formulation of the boundary conditions of option
valuation formula is one of such approaches. In this paper we focus on the
impact of Dirichlet, Neumann and transparent boundary conditions when the
valuation formula is discretized by the discontinuous Galerkin method
combined with the implicit Euler scheme for the temporal discretization. The
numerical results are presented using real data of DAX index options.
Extreme return, extreme volatility and investor sentiment
Authors: Gong Xu , Wen Fenghua , He Zhifang , Yang Jia , Yang Xiaoguang , Pan Bin
Published: March 2017

The extreme return and extreme volatility have great influences on the
investor sentiment in stock market. However, few researchers have taken the
phenomenon into consideration. In this paper, we first distinguish the
extreme situations from non-extreme situations. Then we use the ordinary
generalized least squares and quantile regression methods to estimate a
linear regression model by applying the standardized AAII, the return and
volatility of SP 500. The results indicate that, except for extremely
negative return, other return sequences can cause great changes in investor
sentiment, and non-extreme return plays a leading role in affecting the
overall American investor sentiment. Extremely positive (negative) return can
rapidly improve (further reduce) the level of investor sentiment when
investors encounter extremely pessimistic situations. The impact gradually
decreases with improvement of the sentiment until the situation turns
optimistic. In addition, we find that extreme and non-extreme volatility
cannot a_ect the overall investor sentiment.

Authors: Chai Jian , Lu Quan-Ying , Ye Yun-Xiao , Huang Zang-Hong , Lai Kin
Published: March 2017

Chinese economy entered New Normal development stage in 2014. The stock and
increment of traffic infrastructure and transport equipment will be maintain
at a large scale. The continuous increase in the demand of transportation has
brought about the increase of transportation energy consumption and pollution
emission. In this paper, we focus on road transportation energy consumption.
Firstly, analyze the core influence factors of road transportation energy
consumption, and establish a road transportation energy consumption BVAR
model. Secondly, introduce the loss function when establishing BVAR model in
order to explain the asymmetric effect. Therefore, combine the merits of the
loss function and BVAR model, and compare difference in loss when the
regression coefficient is too high or too low under normal-Wishart prior
distribution. The results show that the response of road transportation
energy consumption to total turnover volume (i.e. ZZ) and mileage (i.e. LC)
are observably, the mileage is a caused demand. Contribution rate of road
transportation energy consumption itself is the largest, about 93%, and it
has stock (up-tail) effect. Contribution rate of total turnover volume and
mileage to road transportation energy consumption keep at about 6% and 1%
respectively. There is asymmetric effect between road transportation energy
consumption and its influence factors, Value a will affect the estimated
result. The deviation of estimated values when a > 0 are large than the
estimated values when a < 0.

China?s current vehicle emissions caused by air pollution problems have
become increasingly prominent. How to improve new energy vehicle market
share, and effectively guide the consumer buying behavior become a problem,
which the government and social have to be solved. In this paper, according
to establish the stochastic evolutionary game model between the government
and consumers in the car market, introducing of random factors analysis on
the impact of evolutionary stability ,will obtain the stable strategy of
government and automotive consumers. And on the basis of it, we study the
government support, cost of vehicles, the use of cost, the utility of
automobile use for the ways of evolutionary stability, with case further
illustrates the external disturbance factors on consumer purchase of new
energy vehicles in evolutionary game process stability. Studies show that:
the increasing government subsidy policy, the reducing life cycle costs of
new energy vehicles and the improving effectiveness of new energy vehicles
will lead the model?s evolution to the orientation of consumer purchasing new
energy vehicles.
Correlation analysis of industry sectors in China’s stock markets based on interval data
Authors: Long Wen , Tang Yeran , Cao Dingmu
Published: March 2017

Comparing with single value data, interval data is an important data type
containing more information. This paper focuses on correlation analysis of
interval data and proposes a comprehensive weighted correlation coefficient
which combines both trend and range information of a sequence. Applying the
new approach of interval data correlation coefficient to China?s stock market,
we obtain the empirical value of the weight taking CSI 300 as the
representative. Further, the correlations between industry sectors as well
as the sample stocks within a specific industry sector are analyzed
respectively using this method. The empirical studies suggest that the
correlation coefficient of interval data has improved the results of
traditional correlation coefficient and the temporal fluctuation
characteristics of the sequence are better reflected based on interval data.

Published: March 2017

Insulin resistance is a major health risk, and although exercise clearly improves skeletal muscle insulin sensitivity, the mechanisms are unclear. Here we show that initiation of a euglycemic-hyperinsulinemic clamp 4 h after single-legged exercise in humans increased microvascular perfusion (determined by contrast-enhanced ultrasound) by 65% in the exercised leg and 25% in the rested leg (P < 0.05) and that leg glucose uptake increased 50% more (P < 0.05) in the exercised leg than in the rested leg. Importantly, infusion of the nitric oxide synthase inhibitor l-NG-monomethyl-l-arginine acetate (l-NMMA) into both femoral arteries reversed the insulin-stimulated increase in microvascular perfusion in both legs and abrogated the greater glucose uptake in the exercised compared with the rested leg. Skeletal muscle phosphorylation of TBC1D4 Ser318 and Ser704 and glycogen synthase activity were greater in the exercised leg before insulin and increased similarly in both legs during the clamp, and l-NMMA had no effect on these insulin-stimulated signaling pathways. Therefore, acute exercise increases insulin sensitivity of muscle by a coordinated increase in insulin-stimulated microvascular perfusion and molecular signaling at the level of TBC1D4 and glycogen synthase in muscle. This secures improved glucose delivery on the one hand and increased ability to take up and dispose of the delivered glucose on the other hand.

Introduction

The objective of our study was to present model-based estimates and projections on current and future health and economic impacts of multiple sclerosis (MS) in Canada over a 20-year time horizon (2011–2031).

Methods

Using Statistics Canada’s Population Health Microsimulation Model (POHEM) framework, specifically the population-based longitudinal, microsimulation model named POHEM-Neurological, we identified people with MS from health administrative data sources and derived incidence and mortality rate parameters from a British Columbia population-based cohort for future MS incidence and mortality projections. We also included a utility-based measure (Health Utilities Index Mark 3) reflecting states of functional health to allow projections of health-related quality of life. Finally, we estimated caregiving parameters and health care costs from Canadian national surveys and health administrative data and included them as model parameters to assess the health and economic impact of the neurological conditions.

Results

The number of incident MS cases is expected to rise slightly from 4051 cases in 2011 to 4794 cases per 100 000 population in 2031, and the number of Canadians affected by MS will increase from 98 385 in 2011 to 133 635 in 2031. The total per capita health care cost (excluding out-of-pocket expenses) for adults aged 20 and older in 2011 was about $16 800 for individuals with MS, and approximately $2500 for individuals without a neurological condition. Thus, after accounting for additional expenditures due to MS (excluding out-of-pocket expenses), total annual health sector costs for MS are expected to reach $2.0 billion by 2031. As well, the average out-of-pocket expenditure for people with MS was around $1300 annually throughout the projection period.

Conclusion

MS is associated with a significant economic burden on society, since it usually affects young adults during prime career- and family-building years. Canada has a particularly high prevalence of MS, so research such as the present study is essential to provide a better understanding of the current and future negative impacts of MS on the Canadian population, so that health care system policymakers can best plan how to meet the needs of patients who are affected by MS. These findings also suggest that identifying strategies to prevent MS and more effectively treat the disease are needed to mitigate these future impacts.
Circularly Polarised Hexagonal Patch Antenna With Polygonal Slot for RFID Applications
Authors: K. C Prakash , P. V Vinesh , R Vivek , Ameen Mohammad , K Vasudevan
Published: March 2017

A compact single feed circularly polarized microstrip patch antenna for RFID applications is proposed. Antenna geometry includes a regular hexagon shaped patch with a polygonal slot embedded at the centre. The slot accounts for circular polarization and an area reduction of 22.5 %. It is fabricated on FR4 substrate with dielectric constant 4.4 and size 50 mm x 50 mm x 1.6 mm. The measured results include 10dB impedance bandwidth of 5.5 % at the center frequency of 2.42 GHz, a return loss of 32 dB, minimum axial ratio of 1.82 dB, axial ratio bandwidth of 7.5%, gain of 4.9 dBi with a broadside radiation characteristic for the RHCP antenna. These results are well in tune with the simulated results and the proposed design is suitable for RFID reader antenna applications.
Los fines de un idioma o la "diferencia sexual"
Authors: Berger Anne Emmanuelle
Published: March 2017

En "Los fines de un idioma o la 'diferencia sexual'", se analizan los diferentes usos y significados de la noción de “diferencia sexual” en los mundos francófono y anglófono. La "diferencia sexual" fue elevada al estatus de cuasiconcepto por el psicoanálisis y se convirtió subsecuentemente en uno de los términos clave al reflexionar sobre sexo y género. Al examinar la pluralización de sus usos y la inflexión de sus significados en la teoría de género y la teoría queer en Estados Unidos, la autora resalta su transformación-queer" y reflexiona sobre el cuestionamiento queer contemporáneo del pensamiento feminista. A través del análisis de las interminables diferenciaciones del significado de "diferencia sexual", la autora busca resaltar la heterogeneidad conceptual ?desde su perspectiva, tan irreductible como productiva? del campo teórico de los estudios de género. Se trata asimismo de una forma de interrogar los modos de constitución del eje teórico franco-anglo-americano, que ha dominado el pensamiento feminista en el siglo XX.
El sida en el escenario gay: melodrama didáctico vs locura cáustica. Estudio comparativo: A tu intocable persona de Gonzalo Valdés Medellín y Una visita inoportuna de Copi
Authors: Rousseau Pauline
Published: March 2017

A partir de los años ochenta apareció un tema nuevo en el escenario social y cultural gay: el sida. Tanto las dramáticas consecuencias que la enfermedad tuvo en la comunidad como los discursos discriminadores que provocó fueron temáticas clave de numerosas obras de teatro. Las dos obras que aquí se comparan se centran en esta temática. No obstante, a pesar de ciertas semejanzas, como el cuadro ficcional o los personajes, cada autor configura un sistema de representación que, si bien comprende la lucha contra la discriminación, utiliza técnicas teatrales muy distintas. La risa trágica de Copi y el didacticismo dramático de Valdés Medellín parecen proponer dos formas de resistencia que se inscriben en un contexto histórico y cultural particular, pero que reflejan también metas artísticas y políticas singulares que este artículo se propone estudiar.
Pequeñas conquistas en la adversidad: posibilidades de agencia de mujeres que usan la violencia en Buenos Aires y trabajadoras sexuales en la frontera sur de México
Authors: Beltrán Savenije María Antonieta , Aguirre Laura
Published: March 2017

El presente artículo busca visibilizar las posibilidades de agencia que algunas mujeres tienen incluso cuando viven en limitadas condiciones sociales que restringen sus acciones y que las pueden llevar a sufrir victimización. Con base en dos investigaciones cualitativas: 1) mujeres de barrios populares del conurbano bonaerense que utilizan violencia (2008-2010), y 2) migrantes centroamericanas trabajadoras en el comercio sexual de la frontera sur de México (2011-2013), se muestra su capacidad para tomar decisiones y actuar. Esto se evidencia, en el caso de mujeres que usan violencia, en que saben pelear, defender a otros, impedir que las asalten o forjarse una reputación; en el caso de las migrantes, en mantenerse acompañadas, negociar sus servicios y pagos, huir de las autoridades y trabajar en la calle en lugar de hacerlo en bares.
La belleza es un corsé de acero: Los Pazos de Ulloa y La Desheredada
Authors: Huamán Andía Bethsabé
Published: March 2017

Las novelas del siglo XIX español presentan personajes femeninos atrapados por una demanda de honradez extrema, imposible de cumplir si se trata de una mujer bella. La belleza se entendía como lo opuesto de la virtud y a la virtud se le relacionaba con la obediencia y sumisión al hombre. En el presente artículo, que analiza los personajes femeninos de Los pazos de Ulloa, de Emilia Pardo Bazán, y de La desheredada, de Benito Pérez Galdós, se busca hacer evidentes los mecanismos bajo los cuales la mujer es un objeto de deseo del hombre. Asimismo, se quiere mostrar cómo los demoledores prejuicios bajo los que la mirada masculina la concibe, castran y matan, literal y simbólicamente, sus posibilidades de estar y sobrevivir en la sociedad. Se hará visible cómo, en estos discursos, la única mujer verdaderamente aceptable es la mujer muerta.
Mujeres, hombres y vida familiar en México. Persistencia de la inequidad de género anclada en la desigualdad social
Authors: Rojas Olga Lorena
Published: March 2017

En este trabajo se pretende reflexionar sobre la pertinencia analítica de la encrucijada entre la desigualdad social y el género, para dar cuenta del extenso abanico de posibilidades de las relaciones que establecen hombres y mujeres en la vida familiar en México. Para ello, se tomó en cuenta los resultados de diversas investigaciones, sobre todo de corte cualitativo y desde el campo de las ciencias sociales, que han reportado importantes modificaciones en la organización y el funcionamiento de las familias como resultado de los cambios sociales, demográficos, económicos y culturales experimentados en el país en las últimas décadas. Con este objetivo en mente, se pone a prueba la capacidad explicativa de algunas propuestas teóricas que se han desarrollado sobre las transformaciones en la vida íntima, producto de los cambios sociales y culturales que ha traído consigo la modernidad en las sociedades más desarrolladas.
Iniciación sexual y construcción del deseo en varones con prácticas homoeróticas en el eje cafetero colombiano
Authors: Gallego Montes Gabriel , Giraldo Aguirre Sebastián
Published: March 2017

Este artículo presenta un acercamiento a la iniciación sexual entre varones con prácticas homoeróticas en el Eje Cafetero colombiano. La revisión de literatura evidencia el predominio de una mirada epidemiológica asociada al VIH/SIDA en los estudios sobre sexualidad juvenil. La investigación fue llevada a cabo en el año 2012, a través de una encuesta biográfica a 401 hombres, en las ciudades de Manizales, Pereira, Armenia y Cartago. Los hallazgos detallan la construcción del deseo y la primera experiencia sexual, sus contextos de ocurrencia y una relación entre prácticas sexuales y diferencias de edad con la pareja. Como conclusión puede advertirse que la construcción del deseo y las prácticas sexuales conjugan de manera problemática los campos del homoerotismo y heterosexualidad.
De niñas escolares a madres y esposas: restricciones a la educación femenina en Colombia durante la temprana vida republicana, 1820-1828
Authors: Pita Pico Roger
Published: March 2017

Este artículo intenta abordar los obstáculos del naciente gobierno republicano en implementar un sistema educativo incluyente que cobijara a las mujeres. Escasos fueron los avances en estos años por superar la mentalidad segregacionista y los desfases que en materia educativa habían primado durante el periodo de dominio hispánico. Así entonces, los principios republicanos de igualdad y libertad no se vieron reflejados en la política educativa que resultó afectada por la crisis económica, el déficit fiscal y los estragos causados por las guerras de Independencia. Por consiguiente, las integrantes del género femenino continuaron bajo la influencia de la Iglesia y la moral católica, reiterándoseles su papel de madres y esposas al interior de la familia. Finalmente, ellas vieron cómo se aplazaba el ejercicio pleno de sus derechos como ciudadanas, con lo cual se coartaron sus oportunidades de desarrollo personal, reconocimiento y ascenso socioeconómico.
Del antipatriarcado al feminismo: derivas del ethos militante en un movimiento social de la Argentina (2004-2015)
Authors: Longa Francisco
Published: March 2017

El presente artículo se ocupa de observar el recorrido de la cuestión de género en un movimiento social contemporáneo en Argentina, a partir de las tendencias prefigurativas o pragmáticas que muestran los ethos militantes. Se trabajó para ello con entrevistas en profundidad, observaciones de campo y análisis de los documentos producidos por el Frente Popular Darío Santillán (FPDS). Los resultados de este trabajo permiten corroborar la presencia de un ethos prefigurativo relativo a la cuestión de género en este movimiento, al tiempo que ayudan a relativizar las divisiones tajantes entre los “viejos” y los “nuevos”’ modelos de militancia, encontrando continuidades y rupturas entre ellos. Estos resultados se enmarcan en las conclusiones generales de mi estudio de maestría del año 2013.
Estudo diacrônico da colocação pronominal em complexos verbais na escrita do PB e do PE (séculos XIX e XX)
Authors: Nunes Carla Da Silva
Published: March 2017

Este artigo trata do tema da colocação do clítico “se” em complexos verbais nas amostras brasileira e europeia. Vale-se de corpus da modalidade escrita de editoriais, notícias e anúncios produzidos nos séculos XIX e XX. Com base na sociolinguística laboviana, desenvolve-se o tratamento estatístico dos dados provido pelo Goldvarb-X. Investigam-se, então, as trajetórias dos diferentes tipos de “se”, para se atestar as possíveis semelhanças e diferenças entre as escritas brasileira e europeia. Além disso, verifica-se se o comportamento dos dados reflete a existência de uma regra variável. Assim, analisam-se os possíveis condicionamentos linguísticos favorecedores de cl V1 V2 (se pode fazer), V1-cl V2 (pode-se fazer), V1 cl V2 (pode se fazer) e V1 V2-cl (pode fazer-se). Observa-se que a escrita, por vezes, aproxima as normas, como no contexto de início absoluto de período/oração, em se que recusa a próclise a V1 nas duas amostras, e aos complexos participiais, que não registram dados de ênclise a V2. Os padrões cultos escritos brasileiro e europeu assemelham-se, especificamente, no caso do indeterminador, nos dois séculos em questão. Por outro lado, o uso do reflexivo parece ser a questão central na diferenciação entre as duas normas estudadas. Enquanto os brasileiros parecem vincular suas escolhas aos tipos de “se”, em que o reflexivo tende a figurar adjacente a V2 (inclusive em próclise) e o indeterminador adjacente a V1, os europeus o fazem de forma mais suave e parecem relacionar suas escolhas também à forma do verbo principal e à presença de “proclisador”, especialmente com o indeterminador. A atuação do “proclisador” com o reflexivo é branda também no PE, mesmo assim, um pouco mais efetiva do que no PB. Ao final do século XX, as diferenças evidenciam-se ainda mais quando se registra o aumento da próclise a V2 no Brasil. No PE a variante não é empregada.

Jumping spiders are capable of estimating the distance to their prey relying only on the information from one of their main eyes. Recently, it has been shown that jumping spiders perform this estimation based on image defocus cues. In order to gain insight into the mechanisms involved in this blur-to-distance mapping as performed by the spider and to judge whether inspirations can be drawn from spider vision for depth-from-defocus computer vision algorithms, we constructed a three-dimensional (3D) model of the anterior median eye of the Metaphidippus aeneolus, a well studied species of jumping spider. We were able to study images of the environment as the spider would see them and to measure the performances of a well known depth-from-defocus algorithm on this dataset. We found that the algorithm performs best when using images that are averaged over the considerable thickness of the spider’s receptor layers, thus pointing towards a possible functional role of the receptor thickness for the spider’s depth estimation capabilities.

Published: March 2017

A numerical procedure was performed to simplify the complicated mechanism of an epitaxial thin-film growth process. In this study, three numerical mechanism models are presented for verifying the growth rate of the gallium nitride (GaN) mechanism. The mechanism models were developed through rate of production analysis. All of the results can be compared in one schematic diagram, and the differences among these three mechanisms are pronounced at high temperatures. The simplified reaction mechanisms were then used as input for a two-dimensional computational fluid dynamics code FLUENT, enabling the accurate prediction of growth rates. Validation studies are presented for two types of laboratory-scale reactors (vertical and horizontal). A computational study including thermal and flow field was also performed to investigate the fluid dynamic in those reactors. For each study, the predictions agree acceptably well with the experimental data, indicating the reasonable accuracy of the reaction mechanisms.
Strength of Alkane–Fluid Attraction Determines the Interfacial Orientation of Liquid Alkanes and Their Crystallization through Heterogeneous or Homogeneous Mechanisms
Authors: Qiu Yuqing , Molinero Valeria
Published: March 2017

Alkanes are important building blocks of organics, polymers and biomolecules. The conditions that lead to ordering of alkanes at interfaces, and whether interfacial ordering of the molecules leads to heterogeneous crystal nucleation of alkanes or surface freezing, have not yet been elucidated. Here we use molecular simulations with the united-atom OPLS and PYS alkane models and the mW water model to determine what properties of the surface control the interfacial orientation of alkane molecules, and under which conditions interfacial ordering results in homogeneous or heterogeneous nucleation of alkane crystals, or surface freezing above the melting point. We find that liquid alkanes present a preference towards being perpendicular to the alkane–vapor interface and more parallel to the alkane–water interface. The orientational order in the liquid is short-ranged, decaying over ~1 nm of the surface, and can be reversed by tuning the strength of the attractions between alkane and the molecules in the other fluid. We show that the strength of the alkane–fluid interaction also controls the mechanism of crystallization and the face of the alkane crystal exposed to the fluid: fluids that interact weakly with alkanes promote heterogeneous crystallization and result in crystals in which the alkane molecules orient perpendicular to the interface, while crystallization of alkanes in the presence of fluids, such as water, that interact more strongly with alkanes is homogeneous and results in crystals with the molecules oriented parallel to the interface. We conclude that the orientation of the alkanes at the crystal interfaces mirrors that in the liquid, albeit more pronounced and long-ranged. We show that the sign of the binding free energy of the alkane crystal to the surface, ΔGbind, determines whether the crystal nucleation is homogeneous (ΔGbind ≥ 0) or heterogeneous (ΔGbind < 0). Our analysis indicates that water does not promote heterogeneous crystallization of the alkanes because water stabilizes more the liquid than the crystal phase of the alkane, resulting in ΔGbind > 0. While ΔGbind < 0 suffices to produce heterogeneous nucleation, the condition for surface freezing is more stringent, ΔGbind < −2 γxl, where γxl is the surface tension of the liquid–crystal interface of alkanes. Surface freezing of alkanes is favored by their small value of γxl. Our findings are of relevance to understanding surface freezing in alkanes and to develop strategies for controlling the assembly of chain-like molecules at fluid interfaces.
Thermoeconomic Optimization of an Irreversible Novikov Plant Model under Different Regimes of Performance

Published: March 2017

The so-called Novikov power plant model has been widely used to represent some actual power plants, such as nuclear electric power generators. In the present work, a thermo-economic study of a Novikov power plant model is presented under three different regimes of performance: maximum power (MP), maximum ecological function (ME) and maximum efficient power (EP). In this study, different heat transfer laws are used: The Newton’s law of cooling, the Stefan–Boltzmann radiation law, the Dulong–Petit’s law and another phenomenological heat transfer law. For the thermoeconomic optimization of power plant models, a benefit function defined as the quotient of an objective function and the total economical costs is commonly employed. Usually, the total costs take into account two contributions: a cost related to the investment and another stemming from the fuel consumption. In this work, a new cost associated to the maintenance of the power plant is also considered. With these new total costs, it is shown that under the maximum ecological function regime the plant improves its economic and energetic performance in comparison with the other two regimes. The methodology used in this paper is within the context of finite-time thermodynamics.

Published: March 2017

In this paper, an opposed-piston two-stroke (OP2S) gasoline direct injection (GDI) engine is introduced and its working principles and scavenging process were analyzed. An optimization function was established to optimize the scavenging system parameters, include intake port height, exhaust port height, intake port circumference ratio, the exhaust port circumference ratio and opposed-piston motion phase difference. The effect of the port height on the effective compression ratio and effective expansion ratio were considered, and indicated mean effective pressure (IMEP) was employed as the optimization objective instead of scavenging efficiency. Orthogonal experiments were employed to reduce the calculation work. The effect of the scavenging parameters on delivery ratio, trapping ratio, scavenging efficiency and indicated thermal efficiency were calculated, and the best parameters were also obtained by the optimization function. The results show that IMEP can be used as the optimization objective in the uniflow scavenging system; intake port height is the main factor to the delivery ratio, while exhaust port height is the main to engine trapping ratio, scavenging efficiency and indicated thermal efficiency; exhaust port height is the most important factor to effect the gas exchange process of OP2S-GDI engine.
Inhibition of Listeria monocytogenes on Ready-to-Eat Meats Using Bacteriocin Mixtures Based on Mode-of-Action
Authors: Vijayakumar Paul , Muriana Peter
Published: March 2017

Bacteriocin-producing (Bac+) lactic acid bacteria (LAB) comprising selected strains of Lactobacillus curvatus, Lactococcus lactis, Pediococcus acidilactici, and Enterococcus faecium and thailandicus were examined for inhibition of Listeria monocytogenes during hotdog challenge studies. The Bac+ strains, or their cell-free supernatants (CFS), were grouped according to mode-of-action (MOA) as determined from prior studies. Making a mixture of as many MOAs as possible is a practical way to obtain a potent natural antimicrobial mixture to address L. monocytogenes contamination of RTE meat products (i.e., hotdogs). The heat resistance of the bacteriocins allowed the use of pasteurization to eliminate residual producer cells for use as post-process surface application or their inclusion into hotdog meat emulsion during cooking. The use of Bac+ LAB comprising 3× MOAs directly as co-inoculants on hotdogs was not effective at inhibiting L. monocytogenes. However, the use of multiple MOA Bac+ CFS mixtures in a variety of trials demonstrated the effectiveness of this approach by showing a >2-log decrease of L. monocytogenes in treatment samples and 6–7 log difference vs. controls. These data suggest that surface application of multiple mode-of-action bacteriocin mixtures can provide for an Alternative 2, and possibly Alternative 1, process category as specified by USDA-FSIS for control of L. monocytogenes on RTE meat products.
Phosphoinositides, Major Actors in Membrane Trafficking and Lipid Signaling Pathways
Authors: De Craene Johan-Owen , Bertazzi Dimitri , Bär Séverine , Friant Sylvie
Published: March 2017

Phosphoinositides are lipids involved in the vesicular transport of proteins and lipids between the different compartments of eukaryotic cells. They act by recruiting and/or activating effector proteins and thus are involved in regulating various cellular functions, such as vesicular budding, membrane fusion and cytoskeleton dynamics. Although detected in small concentrations in membranes, their role is essential to cell function, since imbalance in their concentrations is a hallmark of many cancers. Their synthesis involves phosphorylating/dephosphorylating positions D3, D4 and/or D5 of their inositol ring by specific lipid kinases and phosphatases. This process is tightly regulated and specific to the different intracellular membranes. Most enzymes involved in phosphoinositide synthesis are conserved between yeast and human, and their loss of function leads to severe diseases (cancer, myopathy, neuropathy and ciliopathy).
