description: Protoplasmic streaming in plant cells is directly visible in the cases of \textit{Chara corallina} and \textit{Nitella flexilis}, and this streaming is understood to play a role in the transport of biological materials. For this reason, related studies have focused on molecular transportation from a fluid mechanics viewpoint. However, the experimentally observed distribution of the velocity along the flow direction $x$, which exhibits two peaks at $V_x\!=\!0$ and at a finite $V_x(\not=\!0)$, remains to be studied. In this paper, we numerically study whether this behavior of the flow field can be simulated by a 2D stochastic Navier-Stokes (NS) equation for Couette flow, in which random Brownian force is assumed. We present the first numerical evidence that these peaks are reproduced by the stochastic NS equation, which implies that the Brownian motion of the fluid particles plays an essential role in the emergence of these peaks in the velocity distribution. We also find that the position of the peak at $V_x(\not=\!0)$ moves with the variation in the strength $D$ of the random Brownian force, which also changes depending on physical parameters such as the kinematic viscosity, boundary velocity and diameter of the plant cells.

description: More than 50 years ago, in 1969, police raided a gay bar in New York’s Greenwich Village, sparking a series of demonstrations, protests, and formal organizing that continues in various forms to this day. The event wasn’t the first time police had raided a gay bar but it became a turning point that increased the visibility of LGBTQ Americans and highlighted their lack of equal rights. Change for a more equitable America came slowly and in unexpected places, such as in Bunceton, Missouri, population 353. It was here where Americans elected in 1980 the country's first openly gay mayor, Gene Ulrich, a person who defied small-town America's expectations regarding sexuality, religion, business, politics, and civic engagement.

description: Lime oil, as a by-product of lime processing, has a variety of food and industrial uses. Mexico is currently the world’s leading producer of lime oil, and has an interest in possible expansion of the industry. The primary market is the U.S., with lesser potential in the EU based on past trends. Expansion of this industry, if feasible, would increase producer revenue and add jobs in lime processing and allied and secondary sectors of the economy, spurring economic development in affected rural areas of Mexico. Juice for human consumption and pulp for animal feed are also products of lime processing but are fraught with commodity characteristics. Lime oil, on the other hand, is an ingredient in differentiated food and cosmetic products and appears to be associated with fairly stable prices over time even in the face of competition from Brazil and Peru. This study determines the economic feasibility and potential extent of expanding lime-oil production in Mexico.

description: Millions of pounds of fresh fruits, vegetables, cut flowers, herbs, and other agricultural and food products enter the United States via commercial shipments from other countries every year. Although these items appear harmless, there could be hidden threats in that baggage and in those truckloads, trainloads, and containers of fresh and processed food items that could seriously threaten U.S. agriculture, its natural resources, and its economy (U.S. Customs and Border Protection 2007). Food imports play a major role in the success and competitiveness of various agribusiness firms in the United States. For example, food imports generate income, employment, output, and taxes and provide consumers with lower-priced products than those produced or purchased in the domestic markets. Food imports also provide consumers with a larger variety of products that normally would not be available to them, or that would be available in limited quantities and at higher than normal prices. Consequently, without food imports many U.S. food processing and manufacturing firms would be forced to reduce plant capacity, re-locate food processing and manufacturing facilities, or close plants altogether (Rosson 2000). Thus it is important that food imports that do not comply with U.S. standards be targeted, detected, and intercepted, thereby preventing the entry of those potential threats before they have the chance to do any harm to the U.S food system and its infrastructure.

description: In multi-stage press hardening, the product properties are determined by the thermo-mechanical history during the sequence of heat treatment and forming steps. To measure these properties and finally to control them by feedback, two soft sensors are developed in this work. The press hardening of 22MnB5 sheet material in a progressive die, where the material is first rapidly austenitized, then pre-cooled, stretch-formed, and finally die bent, serves as the framework for the development of these sensors. To provide feedback on the temporal and spatial temperature distribution, a soft sensor based on a model derived from the Dynamic mode decomposition (DMD) is presented. The model is extended to a parametric DMD and combined with a Kalman filter to estimate the temperature (-distribution) as a function of all process-relevant control variables. The soft sensor can estimate the temperature distribution based on local thermocouple measurements with an error of less than 10 °C during the process-relevant time steps. For the online prediction of the final microstructure, an artificial neural network (ANN)-based microstructure soft sensor is developed. As part of this, a transferable framework for deriving input parameters for the ANN based on the process route in multi-stage press hardening is presented, along with a method for developing a training database using a 1-element model implemented with LS-Dyna and utilizing the material model Mat248 (PHS_BMW). The developed ANN-based microstructure soft sensor can predict the final microstructure for specific regions of the formed and hardened sheet in a time span of far less than 1 s with a maximum deviation of a phase fraction of 1.8 % to a reference simulation.

description: We reinterpret the Scherk-Schwarz (SS) boundary condition for SU(2)_R in a compactified five-dimensional (5D) Poincare supergravity in terms of the twisted SU(2)_U gauge fixing in 5D conformal supergravity. In such translation, only the compensator hypermultiplet is relevant to the SS twist, and various properties of the SS mechanism can be easily understood. Especially, we show the correspondence between the SS twist and constant superpotentials within our framework.

description: Documentary representations of queer life in the United States have historically been absent or context poor, especially prior to the onset of the AIDS crisis in the 1980s. Noted photographer Tom Bianchi bucked this trend and offered an alternative view of gay life in the 1970s and 1980s through his 2013 photo book, Fire Island Pines: Polaroids, 1975–1983. The work provides a much-needed window into gay life during this period where cameras were regarded as threats, and scant documentary-style depictions exist. Through a content analysis and in-depth interview informed by feminist theory, this study explores the politics of belonging and offers insight to practitioners interested in providing nuanced depictions of marginalized groups.

description: As part of the global economy, agriculture and agribusiness of the State of Idaho have been significantly affected by the structural changes taking place in the food-supply chain. Constantly changing consumer preferences, new technologies, and globalization represent both challenges and opportunities for the food-supply-chain participants. The very diverse agriculture of Idaho provides a favorable market environment for agricultural producers and food companies to become involved in various food-manufacturing activities. This paper focuses on the quantitative evaluation of the economic performance of food-manufacturing industries in Idaho, using U.S. Economic Census data for 1997 and 2002. The results have implications for the strategic decision-making of the food-supply-chain participants and government authorities.

description: The Steer-by-Wire (SbW) system is a key technology for highly automated driving. For automated lateral vehicle guidance, the precise position control of the SbW Front Axle Actuator is an essential prerequisite. This contribution presents the modeling, control design, nominal performance, and stability analysis as well as the robustness analysis of the position control for the SbW Front Axle Actuator. Based on a nonlinear model of the plant a simplified linear system model is derived. This model yields the basis for the design of a Two-Degrees of Freedom Linear Quadratic Gaussian Control (2DOF LQG control), which allows an independent design of the command and the disturbance response. Besides an evaluation of the nominal control behavior, μ-analysis is applied to assess the robustness of performance and stability. Finally, real vehicle tests for different driving maneuvers are presented to verify simulation results.
description: Die Steer-by-Wire (SbW) Lenkung ist eine Schlüsseltechnologie für hochautomatisiertes Fahren. Für die automatisierte Fahrzeugquerführung ist dabei eine präzise Positionsregelung des SbW Vorderachsaktuators wesentliche Voraussetzung. Dieser Beitrag beschreibt die Modellbildung, Reglersynthese, Analyse der nominalen Regelgüte und Stabilität sowie die Robustheitsanalyse einer Positionsregelung für den SbW Vorderachsaktuator. Ausgehend von einem nichtlinearen Modell der Regelstrecke wird ein vereinfachtes lineares Systemmodell entwickelt. Dieses bildet die Grundlage für den Entwurf einer Zwei-Freiheitsgrade Linear Quadratisch Gaußschen Positionsregelung (2DOF LQG Regelung), welche es ermöglicht, das Führungs- und das Störverhalten unabhängig voneinander einzustellen. Neben der Evaluation der nominalen Regelgüte erfolgt eine μ-Analyse, um die Robustheit der Regelgüte und Stabilität zu bewerten. Abschließend werden reale Fahrversuche mit verschiedenen Fahrmanövern vorgestellt, um die Ergebnisse aus der Simulation zu verifizieren.

description: We present first results of our search for high-redshift galaxies in deep CCD mosaic images. As a pilot study for a larger survey, very deep images of the Chandra Deep Field South (CDFS), taken withWFI@MPG/ESO2.2m, are used to select large samples of 1070 U-band and 565 B-band dropouts with the Lyman-break method. The data of these Lyman-break galaxies are made public as an electronic table. These objects are good candidates for galaxies at z~3 and z~4 which is supported by their photometric redshifts. The distributions of apparent magnitudes and the clustering properties of the two populations are analysed, and they show good agreement to earlier studies. We see no evolution in the comoving clustering scale length from z~3 to z~4. The techniques presented here will be applied to a much larger sample of U-dropouts from the whole survey in near future.

Edens d’acclimatation : l’utopie positiviste chez Honoré de Balzac et Émile Zola
Creators: name: Narayana, Valérie Catherine
Publisher: name: University of British Columbia
Year: 2009

description: My dissertation deals with Utopian writing in Honore de Balzac's "Le Medecin de campagne" (1833) and Emile Zola's "Travail (1901). From a theoretical point of view, I argue that while it might seem contradictory for Realist or Naturalist authors to be writing Utopias, this type of fiction, with its highly axiomatized discourse and its will to grasp material norms, is in fact compatible with these authors' scientific and documentary aspirations. I suggest that prior to the refutation of positivism by logicians of science in the mid-1900s, the idea of separating «physics» from «metaphysics» haunted scientific and social thinking. The quest for this demarcation informs all attempts to characterize society in what I call positivist utopianism. In the case of Balzac, "Le Medecin de campagne" attempts to carry out a logical demonstration of the benefits associated with agrarian reforms achieved in a rural community on the eve of Louis Philippe's constitutional monarchy. Though the discourse on the village's economic and social rebirth is delivered in a largely deductive fashion, the premises - religious or liberal – of this axiomatisation are never made clear. In Zola's "Travail", the elaboration of the fictional community takes a different form. Here, the premise of social perfectibility is given, held to, and demonstrated quite consistently, save for a few problematic but meaningful exceptions. Indeed, the novel's predictability is such that the work's artistic merit came under fire at the time of its publication. By positioning the work in its historical context, I suggest that the very simplicity of its stance is highly polemic. Written in light of the Dreyfus affair and of Emile Poincare's scientific popularizing, the novel can be read as an exploration of the woes and freedom of trying to write "scientifically" while acknowledging that mere convention governs truth. I conclude that "Le Medecin de campagne" and "Travail", appearing at pivotal historical moments in post-Revolutionary France, herald social as well as scientific modernity. They yield a problematic representation of the social object whose existence in language and material reality both enables the Utopian project and frustrates it.

description: In haemoglobin (consisting of four globular myoglobin-like subunits), the change from the low-spin (LS) hexacoordinated haem to the high spin (HS) pentacoordinated domed form upon ligand detachment and the reverse process upon ligand binding, represent the transition states that ultimately drive the respiratory function. Visible-ultraviolet light has long been used to mimic the ligand release from the haem by photodissociation, while its recombination was monitored using time-resolved infrared to ultraviolet spectroscopic tools. However, these are neither element- nor spin-sensitive. Here we investigate the transition state in the case of Myoglobin-NO (MbNO) using femtosecond Fe Kalpha and Kbeta non-resonant X-ray emission spectroscopy (XES) at an X-ray free-electron laser upon photolysis of the Fe-NO bond. We find that the photoinduced change from the LS (S = 1/2) MbNO to the HS (S = 2) deoxy-myoglobin (deoxyMb) haem occurs in ca. 800 fs, and that it proceeds via an intermediate (S = 1) spin state. The XES observables also show that upon NO recombination to deoxyMb, the return to the planar MbNO ground state is an electronic relaxation from HS to LS taking place in ca. 30 ps. Thus, the entire ligand dissociation-recombination cycle in MbNO is a spin cross-over followed by a reverse spin cross-over process.

description: Over the last decade consumers’ health consciousness is becoming an important factor driving the agrofood market. Healthier food products have entered the global markets with force in the past years and rapidly gained market share. Consequently, the food industry has reacted to this trend by developing a growing variety of new products with health-related claims and images, including organic and functional foods that are selected by consumers for their health-promoting properties. Currently, the healthy foods and drinks market is performing well, in terms of innovation and market penetration; healthy foods in Europe have a turnover of € 5.7 billion. Different researches conclude that a better understanding of consumers' perception of healthy foods and its determinants are key success factors for market orientation and development and for successfully negotiating market opportunities. The research proposes a survey of 300 Italian consumers in order to understand attitudes towards healthy foods, with particular reference to organic and functional products, through the implementation of a cluster analysis. The main aim of this paper is to derive indications that may contribute to better strategic and tactical marketing decisions. The findings of this study are also important for government bodies interested in designing public health programs.

description: A majority of Americans distrust the news media due to concerns over comprehensiveness, accuracy, and fairness. Since many interactions between journalists and their subjects last only minutes and can be published within seconds, if not live, research is needed to explore how journalists' understandings of their subjects' narratives evolve over time and how much time is necessary to avoid surface-level coverage. Also, since people are now exposed to more image-based rather than text-based messages, additional research is necessary to explore how the verbal narratives spoken by subjects compare to their nonverbal narratives as captured by news photographers in visual form. Through a longitudinal, interview-based approach, a photojournalist working on a 30-plus-day picture story was interviewed weekly for six weeks over the course of his project to track perceptions of how his subjects' verbal narratives changed. At the conclusion of the project, the photojournalist's subjects were also interviewed to explore how their verbal and nonverbal narratives compared. Informed by literature in role theory, narrative, and visual journalism, the findings explore how news media narratives can be more nuanced and how people shape their visual and verbal narratives consciously and unconsciously. Additional findings suggest that comprehensiveness, accuracy, and fairness are intimately related to interaction duration and that visual narratives can highlight role conformity and conflict in ways not possible through verbal narratives alone.

A symplectic Sp(3,R)$\supset$U(3) dynamical symmetry is identified in ab initio predictions, from a no-core configuration interaction approach, and found to provide a qualitative understanding of the spectrum of 7Be. Low-lying states form an Elliott SU(3) spectrum, while an Sp(3,R) excitation gives rise to an excited rotational band with strong quadrupole connections to the ground state band.

description: We have obtained microscopic evidence of the influence of domain wall stray fields on the nanosecond magnetization switching in magnetic trilayer systems. The nucleation barrier initiating the magnetic switching of the soft magnetic Fe20Ni80 layer in magnetic tunnel junction-like FeNi/Al2O3/Co trilayers is considerably lowered by stray fields generated by domain walls present in the hard magnetic Co layer. This internal bias field can significantly increase the local switching speed of the soft layer. The effect is visualized using nanosecond time- and layer-resolved magnetic domain imaging and confirmed by micromagnetic simulations.

description: In view of the importance of the nonperturbative resolved contributions for the overall uncertainties of the two inclusive penguin decays $\bar B \to X_s γ$ and $\bar B \to X_{s,d} \ell^+\ell^-$ we reanalyse these contributions using new estimates of moments of the subleading shape functions and of other input parameters. Within a systematic approach we find a significant reduction of the nonperturbative uncertainties in the inclusive decay $\bar B \to X_{s,d} \ell^+\ell^-$, but a much less pronounced reduction in the inclusive decay $\bar B \to X_s γ$ compared to a recent analysis on the resolved contributions to the inclusive decay $\bar B \to X_s γ$. We identify the reasons for this discrepancy.

description: A Gyöngyösi Kistérségben végzett felmérés tapasztalatai azt mutatták, hogy élénkült a kistérség földpiaca. A földbérleti díjak és árak egyaránt emelkedő tendenciát mutattak, szélsőséges ingadozások mellett. A vizsgált időszakban ér-tékesítettek termőföldet hektáronként 80 ezer forintért és 4,5 millió forintért is. Egyszerre van jelen a földtől való mindenáron való szabadulás és a vétel szándé-ka. A jövőre nézve a földár és a haszonbérleti díj növekedése várható, de ez az EU átlag alatt alakul hosszabb távon is. A föld birtoklása – helyzetétől függően – a jövőben kimagasló hozamot biztosíthat, és várhatóan meghaladja a lekötött bankbetétek hozamát, sőt esetenként extraprofit is elérhető. A termelőeszközök közül ma már csak a földingatlan és a munkaerő alulértékelt Magyarországon. Ezért – véleményünk szerint – a földingatlan kínálkozik utolsó befektetési lehetőségként extraprofit eléréséhez. - The evaluation conducted in the Gyöngyös small region shows that the small region’s land market is picking up. Land rental fees and land prices both show a rising tendency, coupled with extreme fluctuations. In the period under examination, agricultural land was sold for 80,000 forints per hectare, as well as for 4.5 million forints/ha. Both the desire to be rid of land and the intention to purchase exists simultaneously. In the future, both land prices and tenancy fees can be expected to rise, while remaining below the EU average even in the longer-term. Land ownership – depending on location – can guarantee high returns in the future, probably exceeding the returns on fixed bank deposits; in fact, in some cases it can produce extra profit. In Hungary, only land and labour are currently undervalued as tools of production. Therefore, in our opinion, land offers the final investment opportunity for achieving extra profit. It can be stated, based on the investigations conducted in the Gyöngyös small region, that the following have all played a part in the measured growth of land prices and rents: sector profitability; simultaneous supply and demand; fragmented estate structures; the high ratio of common tenancies; the ban on land purchase by capital rich foreign buyers and by national partnerships; significant land left fallow; the aims of land purchase and its later utilisation; advantageous locations; longer rental contracts; the appearance of regionally based government subsidies and their annual growth; the “life annuity for land” programme; and the land rental fee utilised by the National Land Fund (NFA).

description: The photo-production of $ϕ$ mesons from Li, C, Al, and Cu at forward angles has been measured at $E_gamma$=1.5--2.4 GeV. The number of events for incoherent phi photo-production is found to have a target mass number dependence of $A^{0.72\pm 0.07}$ in the kinematical region of $|t|\le 0.6$ ${\rm GeV}^2/c^2$. The total cross section of the $ϕ$-nucleon interaction, $σ_{ϕN}$, has been estimated as $35^{+17}_{-11}$ mb using the $A$-dependence of the $ϕ$ photo-production yield and a Glauber-type multiple scattering theory. This value is much larger than $σ_{ϕN}$ in free space, suggesting that the $ϕ$ properties might change in the nuclear medium.

description: Social media is increasingly being used to support people living with HIV (PLWH). Existing research has not examined the use of images on social media. This study explored the benefits and challenges of using visual social media to support health among ethnically/racially diverse middle-aged adults with HIV in a major midwestern city. This qualitative study utilized posters created from a parent photovoice project to explore participants’ (N = 15) use of social media, interest in viewing posters via social media, and interest in creating their own photo stories for social media. Benefits for social media use included connecting with other PLWH, education, and sharing empowering messages. Challenges were limited technical ability, dislike of/inappropriate use of social media, and concerns for anonymity. Our findings suggest that PLWH want to see photo stories of others living with HIV and that the benefit of viewers creating and sharing their own stories on social media is worth exploring.

description: This paper describes farmer’s exposures to risks at the individual farm level and develops a model representing the decisions of an individual risk averse farmer facing variability in both prices and yields. A set of stylised risk market instruments is represented. The model is calibrated using farm level data from Germany. Monte-Carlo simulations of the random variables are run, and the corresponding optimal responses are obtained. The main focus of this paper is the interactions between government payments and the farmers’ use of risk market instruments in terms of the potential crowding out of such instruments and impacts on farm return and welfare. Unlike other studies this paper models farming response to payments in terms of production and the use of risk market instruments that are endogenous. Single farm payment mitigates farmer’s efforts to reduce farming risk by the potential crowding out of substitutive strategies. Optimal policy crucially depends on the government objective, for instance risk reduction versus farmers’ welfare.

description: We study the convergence rate of the Circumcentered-Reflection Method (CRM) for solving the convex feasibility problem and compare it with the Method of Alternating Projections (MAP). Under an error bound assumption, we prove that both methods converge linearly, with asymptotic constants depending on a parameter of the error bound, and that the one derived for CRM is strictly better than the one for MAP. Next, we analyze two classes of fairly generic examples. In the first one, the angle between the convex sets approaches zero near the intersection, so that the MAP sequence converges sublinearly, but CRM still enjoys linear convergence. In the second class of examples, the angle between the sets does not vanish and MAP exhibits its standard behavior, i.e., it converges linearly, yet, perhaps surprisingly, CRM attains superlinear convergence.
title: Investigation into the therapeutic potential of a clinically compliant amniotic fluid-derived stem cell conditioned media

description: Necrotising enterocolitis (NEC) is a devastating disease that can affect pre-term infants and if survived can lead to long term intestinal damage. Currently a variety of antibiotics and in extreme cases surgery is required to manage the disease. However, no treatment exists that attenuates the widespread cell death and suppresses the innate pro-inflammatory response whilst promoting regeneration in the intestine thus reducing long term damage and the need for surgery. The discovery of stem cells, in particular multipotent stem cells (MSCs) has shown them to have potent regenerative therapeutic properties. In particular, C-kit+ foetal derived MSCs from amniotic fluid (amniotic fluid stem cells - AFSCs) when introduced into a rat model of NEC increased the survival of animals affected whilst also promoting the repair of damaged epithelial layers. Nevertheless, the ability of stem cells to promote regeneration was independent of transplanted cell engraftment. This led to a paradigm shift in which it was proposed that regeneration was via the secretion of factors acting in a paracrine manner with target cells. This was proven by the introduction of stem cell conditioned media (CM), which mimicked the beneficial effect seen when whole MSCs were introduced. However, much of the MSC CM is produced from non-stressed MSCs. Stressing MSCs has been shown to increase the secretion of paracrine factors and the extracellular vesicles that contain them. Creation of an AFSC CM (AF-CM) under conditions of stress using a protocol created by industrial partners was therefore hypothesised to produce a more potent AF-CM beneficial for regeneration and in particular for the treatment of NEC. Here we characterise the AF-CM under conditions of stress but also in a clinically compliant manner. The AF-CM was characterised for protein and RNA content, which elucidated to a multitude of proteins present but interestingly showed that the majority of RNA present was miRNA. In vitro investigation into AF-CM treatment also showed significant improvements in cellular proliferation and migration capacity whilst protecting from senescence. Furthermore, I showed that AF-CM treatment accelerated the regeneration of skeletal muscle fibres following an established mouse model of acute cardiotoxin damage in vivo, of which could be partly attributed to increased blood vasculature.

description: We study the decay rate and the CP violating asymmetry of the exclusive B-> pi ell+ ell- and B-> rho ell+ ell- decays in the case where one of the final leptons is polarized. We calculate the contributions coming from the individual polarization states in order to identify a so-called wrong sign decay, which is a decay with a given polarization, whose width and CP asymmetry are smaller as compared to the unpolarized one. The results are presented for electron and tau leptons. We observe that in particular decay channels, one can identify a wrong sign decay which is more sensitive to new physics beyond the Standard Model.

description: A tanulmány bemutatja a hazai gabona keresletében bekövetkezett vertikális és horizontális átrendeződést és annak hatásait. A kérdőíves megkeresés és a mélyinterjúkból született válaszokat felhasználva, klaszteranalízis segítségével lehetővé vált a felvásárlói oldalon álló szereplők tipizálása, továbbá az áralku döntéseik modellezése. Megállapítható, hogy a gabonapiacon elsősorban a nagy kereskedelmi cégek és holdingok az árvezetők, ami méretükkel, tároló kapacitá-saikkal, logisztikai adottságaikkal és stratégiájukkal magyarázható. A feldolgo-zók (malom, takarmánykeverő, vetőmagos cégek), az integrátorok, kiskereskedők és egyéb cégek árelfogadók a gabonapiacon. Az intervenciós árszint a keresleti oldalon álló szereplők áralkuit, gabonapiaci stratégiáját jelentősen befolyásolja, így a jövőbeni átalakulások egyik generálója lehet. A szerkezeti változásokat az SPS rendszerre való áttérés és a bioetanol-gyártó üzemek megjelenésével párosuló erős gabonakereslet is tovább formálhatja. - The study introduces the vertical and horizontal restructuring that has taken place in domestic grain demand, and its effects. Using the responses to our questionnaire and deep interviews, it was possible with cluster analysis to typify the actors on the purchase side and to model their price deal decisions. It can be stated that large commercial companies and holding groups are primarily the price leaders on the grain market, which can be explained by their size, storage capacity, logistical facility and strategy. The processors (mill, fodder mixer, seed-corn companies), integrators, small retailers and other companies are price-acceptors on the grain market. The intervention price level significantly influences the price deals and grain market strategies of the actors on the demand side, thereby being one of the possible instigators of their future transformation. Structural changes can be further shaped by conversion to the SPS system and strong grain demand coupled with the appearance of bioethanol producing factories.

description: We investigate the clustering properties of galaxies in the recently completed ELAIS-S1 redshift survey through their spatial two point autocorrelation function. We used a sub-sample of the ELAIS-S1 catalog covering approximately 4 deg^2 and consisting of 148 objects selected at 15 micron with a flux >0.5 mJy and redshift z<0.5. We detected a positive signal in the correlation function that, in the range of separations 1-10 h mpc is well approximated by a power law with a slope gamma = 1.4 and a correlation length s =5.4 h mpc. This result is in good agreement with the redshift-space correlation function measured in more local samples of mid infrared selected galaxies like the IRAS PSC$z$ redshift survey. This suggests a lack of significant clustering evolution of infrared selected objects out to $z=0.5$ that is further confirmed by the consistency found between the correlation functions measured in a local (z<0.2) and a distant (0.2

description: Since the insertion area in the middle ear or in the sinus cavity is very narrow, the mobility of the endoscope is reduced to a rotation around a virtual point and a translation for the insertion of the camera. This article first presents the anatomy of these regions obtained from 3D scanning and then a mechanism based on the architecture of the agile eye coupled to a double parallelogram to create an RCM. This mechanism coupled with a positioning mechanism is used to handle an endoscope. This tool is used in parallel to the surgeon to allow him to have better rendering of the medium ear than the use of Binocular scope. The mechanism offers a wide working space without singularity whose borders are fixed by joint limits. This feature allows ergonomic positioning of the patient's head on the bed as well as for the surgeon and allows other applications such as sinus surgery.
