description: Existing research based on labels, risks and benefits, and cultural differences has focused on consumers’ preferences for genetically modified (GM) food products. Limited attention has been paid to the attitudes toward the source who developed the biotechnology. Because there may be trust issues associated with large multinational firms that are often involved in the development of biotechnology, it remains an unexplored question whether consumers consider who produces the technology when forming opinions about food produced with biotechnology. This study investigates consumers’ attitude toward the source of biotechnology using a choice experiment with GM oranges. The study involved participants from three major orange-consuming countries (United States, Germany, and Spain). Results reveal that participants from all three countries were less willing to pay for GM oranges where the technology originated from multinational agribusiness corporations, compared to public universities and small companies. Further examining the effect of consumers’ perceptions, we found consumers’ perception of corporate distrust and environmental concern negatively influence their attitude toward the source of biotechnology, but their technology acceptance positively affects the attitude. By understanding consumers’ attitudes about the source of biotechnology and factors that may improve the consumer reactions, communication, and promotion of new biotechnology food products to improve acceptance from existing and potential consumers are discussed.

description: For any branching process, we demonstrate that the typical total number $r_{\rm mp}(ντ)$ of events triggered over all generations within any sufficiently large time window $τ$ exhibits, at criticality, a super-linear dependence $r_{\rm mp}(ντ) \sim (ντ)^γ$ (with $γ>1$) on the total number $ντ$ of the immigrants arriving at the Poisson rate $ν$. In branching processes in which immigrants (or sources) are characterized by fertilities distributed according to an asymptotic power law tail with tail exponent $1 < γ\leqslant 2$, the exponent of the super-linear law for $r_{\rm mp}(ντ)$ is identical to the exponent $γ$ of the distribution of fertilities. For $γ>2$ and for standard branching processes without power law distribution of fertilities, $r_{\rm mp}(ντ) \sim (ντ)^2$. This novel scaling law replaces and tames the divergence $ντ/(1-n)$ of the mean total number ${\bar R}_t(τ)$ of events, as the branching ratio (defined as the average number of triggered events of first generation per source) tends to 1. The derivation uses the formalism of generating probability functions. The corresponding prediction is confirmed by numerical calculations and an heuristic derivation enlightens its underlying mechanism. We also show that ${\bar R}_t(τ)$ is always linear in $ντ$ even at criticality ($n=1$). Our results thus illustrate the fundamental difference between the mean total number, which is controlled by a few extremely rare realizations, and the typical behavior represented by $r_{\rm mp}(ντ)$.

description: We have calculated continuum limit step scaling functions of bilinear and four-fermion operators renormalized in a Rome-Southampton scheme using various smearing prescriptions for the gauge field. Also, for the first time, we have calculated non-perturbative anomalous dimensions of operators renormalized in a Rome-Southampton scheme. The effect of such smearing first enters connected fermionic correlation functions via radiative corrections. We use off-shell renormalisation as a probe, and observe that the upper edge of the Rome-Southampton window is reduced by link smearing. This can be interpreted as arising due to the fermions decoupling from the high momentum gluons and we observe that the running of operators with the scale at large lattice momenta shows enhanced lattice artefacts. We find that the effect is greater for HEX smearing than for Stout smearing, but that in both cases additional care must be taken when using off-shell renormalisation with smeared gauge fields compared to thin link simulations.

A small value estimate for Ga x Gm
Creators: name: Roy, Damien
Publisher: name: arXiv
Year: 2013
Subjects: subject: Number Theory (math.NT)
subject: FOS: Mathematics

description: A small value estimate is a statement providing necessary conditions for the existence of certain sequences of non-zero polynomials with integer coefficients taking small values at points of an algebraic group. Such statements are desirable for applications to transcendental number theory to analyze the outcome of the construction of an auxiliary function. In this paper, we present a result of this type for the product Ga x Gm whose underlying group of complex points is C x C*. It shows that if a certain sequence of non-zero polynomials in Z[X,Y] take small values at a point (xi,eta) together with their first derivatives with respect to the invariant derivation of the group, then both xi and eta are algebraic over Q. The precise statement involves growth conditions on the degree and norm of these polynomials as well as on the absolute values of their derivatives. It improves on a direct application of Philippon's criterion for algebraic independence and compares favorably with constructions coming from Dirichlet's box principle.

description: Quasistatic simple shearing flow of random monodisperse soap froth is investigated by analyzing Surface Evolver simulations of spatially periodic foams. Elastic-plastic behavior is caused by irreversible topological rearrangements (T1s) that occur when Plateau's laws are violated; the first T1s occur at the elastic limit and at large strains frequent cascades of T1s, composed of one or more individual T1s, sustain the yield-stress plateau. The stress and shape anisotropy of individual cells is quantified by $Q$, a scalar measure derived from the interface tensor that gauges each cell's contribution to the global stress. During each T1 cascade, the connected set of cells with decreasing $Q$, called the \textit{stress release domain}, is network-like and highly non-local. Geometrically, the network-like nature of the stress release domains is corroborated through morphological analysis using the Euler characteristic. The stress release domain is distinctly different from the set of cells that change topology during a T1 cascade. Our results highlight the unique rheological behavior of foams, where complex large-scale cooperative rearrangements of foam cells are observed as a consequence of distinctly local events.

description: The Smart models for Aquifer Management research programme aims to explore the utility and implications of using simple numerical models for decision support applications. This report details a case study example of the application of complex numerical groundwater model as a tool of assessing the effectiveness of land-use resource management scenarios. The case study focuses on the lower Ruamāhanga catchment, Greater Wellington, NZ (Ruamāhanga South). Scenarios relate to nitrate loading change related to distributed change in land-use. The effectiveness of scenarios is assessed relative to desired ecological and societal outcomes related to predicted water quality (nitrate concentrations) in surface- and ground-water. An essential component of the demonstrated use of the numerical model for decision support is the application of probabilistic uncertainty analysis. We use ensemble based calibration and uncertainty analysis techniques (iterative ensemble smoother, iES) to quantify probabilistic uncertainty for a highly parametrised numerical model. iES allows the conditioning of the parameter uncertainty through assimilation of system observation date and propagation of conditioned (posterior) parameter uncertainty through to model predictions. Comparison of prior and posterior parameter uncertainty provides insights into the influence of system observations in conditioning of model parameters, and therefore the ability of data assimilation to reduce predictive uncertainty. Analysis of prediction uncertainty provides a probabilistic description of the likely effectiveness of land-use change in leading to improvement in water quality in the region. Comparison of prior and posterior prediction distributions relative to desired management decision thresholds highlights value (or otherwise) of model calibration efforts in improving the predictive utility of the model.

description: The Smart models for Aquifer Management research programme aims to explore the utility and implications of using simple numerical models for decision support applications. This report details a case study example of the application of a complex numerical groundwater model as a tool of assessing the effectiveness of land- and water-use scenarios. The case study focuses on the upper Ruamāhanga catchment, Greater Wellington, NZ (Ruamāhanga North). The effect of land- and water-use scenarios are assessed relative to desired surface and ground water quality and surface water flow outcomes. Scenarios relate to water abstraction and nitrate loading changes related to distributed changes in land-use. Core to the demonstrated use of the numerical model for decision support is the application of probabilistic uncertainty analysis. Prior parameter uncertainty derived from expert knowledge and upstream modelling efforts is propagated to simulated outputs (predictions). Parameters are conditioned through the assimilation of observation data in a truncated calibration exercise which also informs an estimation of the posterior parameter uncertainty. Through comparing the prior and posterior parameter uncertainties we highlight the apparent capacity of the observation data to inform model parameters. Propagating parameter uncertainties to predictions we explore the value of the complex regional model and the merit of model calibration in decision support modelling. (auth)

description: The visceral stimuli from the digestive tract are transmitted via afferent nerves through the spinal cord to the brain, where they are felt as pain. The overreaction observed in the brain of irritable bowel syndrome (IBS) patients may be due to increased peripheral sensitivity to stimuli from the gastrointestinal tract. Although the exact pathway is uncertain, attenuation of visceral hypersensitivity is still of interest in treating IBS. It has been shown that stress stimulates the sympathetic nervous system while inhibiting the vagus nerve (VN). In addition, stress factors lead to dysbiosis and chronic low-grade inflammation of the intestinal mucosa, which can lead to lower gastrointestinal visceral hypersensitivity. Therefore, an important goal in the treatment of IBS is the normalization of the intestinal microflora. An interesting option seems to be nutraceuticals, including Terminalia chebula, which has antibacterial and antimicrobial activity against various pathogenic Gram-positive and Gram-negative bacteria. Additionally, short-term transcutaneous vagus nerve stimulation can reduce the stress-induced increase in intestinal permeability, thereby reducing inflammation. The conducted studies also indicate a relationship between the stimulation of the vagus nerve (VN) and the activation of neuromodulatory networks in the central nervous system. Therefore, it seems reasonable to conclude that a two-way action through stimulating the VN and using nutraceuticals may become an effective therapy in treating IBS.

description: Sequence alignment data is often ordered by coordinate (id of the reference sequence plus position on the sequence where the fragment was mapped) when stored in BAM files, as this simplifies the extraction of variants between the mapped data and the reference or of variants within the mapped data. In this order paired reads are usually separated in the file, which complicates some other applications like duplicate marking or conversion to the FastQ format which require to access the full information of the pairs. In this paper we introduce biobambam, an API for efficient BAM file reading supporting the efficient collation of alignments by read name without performing a complete resorting of the input file and some tools based on this API performing tasks like marking duplicate reads and conversion to the FastQ format. In comparison with previous approaches to problems involving the collation of alignments by read name like the BAM to FastQ or duplication marking utilities in the Picard suite the approach of biobambam can often perform an equivalent task more efficiently in terms of the required main memory and run-time.

description: The non-relativistic three-body Schrödinger equation of the heteronuclear molecular ion HD$^+$ is solved in perimetric coordinates using the Lagrange-mesh method. Energies and wave functions of the four lowest vibrational bound or quasibound states $v=0-3$ are calculated for total orbital momenta from 0 to 47. Energies are given with an accuracy from about 12 digits for the lowest vibrational level to at least 9 digits for the third vibrational excited level. With a simple calculation using the corresponding wave functions, accurate dipole transition probabilities per time unit between those levels are given over the whole $v=0-3$ rotational bands. Results are presented with six significant figures.

title: Variation of relative complementizers in Yucatecan Spanish: A comparison of monolingual and bilingual speakers
Creators: name: Auhagen, Christopher Patrick
name: Uth, Melanie
Publisher: name: Universität Potsdam
Year: 2023
Subjects: subject: 400 Sprache

description: The starting point of this article is the occurrence of determiner-less and bare que relative complementizers like (en) que, ‘(in) that’, instead of (en) el que, ‘(in) which’, in Yucatecan Spanish (southeast Mexico). While reference grammars treat complementizers with a determiner as the standard option, previous diachronic research has shown that determiner-less complementizers actually predate relative complementizers with a determiner. Additionally, Yucatecan Spanish has been in long-standing contact with Yucatec Maya. Relative complementation in Yucatec Maya differs from that in Spanish (at least) in that the non-complex complementizer tu’ux (‘where’) is generally the only option for locative complementation. The paper explores monolingual and bilingual data from Yucatecan Spanish to discuss the question whether the determiner-less and bare que relative complementizers in our data constitute a historic remnant or a dialectal recast, possibly (but not necessarily) due to language contact. Although our pilot study may not answer these far-reaching questions, it does reveal two separate, but intertwined developments: (i) a generally increased rate of bare que relative complementation, across both monolingual speakers of Spanish and Spanish Maya bilinguals, compared to other Spanish varieties, and (ii) a preference for donde at the cost of other locative complementizer constructions in the bilingual group. Our analysis thus reveals intriguing differences between the complementizer preferences of monolingual and bilingual speakers, suggesting that different variational patterns caused by different (socio-)linguistic factors can co-develop in parallel in one and the [same] region.

description: We develop a statistical physics theory for solid-solid phase transitions in which a metamaterial undergoes longitudinal contraction in response to increase in external tension. Such transitions, which are forbidden in thermodynamic equilibrium, have recently been shown to be possible during the decay of metastable, super-strained states. We present a first-principles model to predict these transitions and validate it using molecular dynamics simulations. Aside from its immediate mechanical implications, our theory points to a wealth of analogous inverted responses, such as inverted susceptibility or heat-capacity transitions, allowed when considering realistic scales.

Compression Instabilities of Tissues with Localized Strain Softening

description: The stress-strain relationship of biological soft tissues affected by Marfan's syndrome is believed to be non-convex. More specifically, Haughton and Merodio recently proposed a strain-energy density leading to localized strain softening, in order to model the unusual mechanical behavior of these isotropic, incompressible tissues. Here we investigate how this choice of strain energy affects the results of some instabilities studies, such as those concerned with the compression of infinite and semi-infinite solids, slabs, and cylinders, or with the bending of blocks, and draw comparisons with known results established previously for the case of a classical neo-Hookean solid. We find that the localized strain softening effect leads to early instability only when instability occurs at severe compression ratios for neo-Hookean solids, as is the case for bulk, surface, and bending instabilities.

description: We present spectroscopic observations acquired with FLAMES and XSHOOTER at the Very Large Telescope for a sample of 15 Blue Straggler Stars (BSSs) in the globular cluster (GC) M30. The targets have been selected to sample the two BSS sequences discovered, with 7 BSSs along the blue sequence and 8 along the red one. No difference in the kinematical properties of the two groups of BSSs has been found. In particular, almost all the observed BSSs have projected rotational velocity lower than ~30 km/s, with only one (blue) fast rotating BSS (>90 km/s), identified as a W UMa binary. This rotational velocity distribution is similar to those obtained in 47 Tucanae and NGC 6397, while M4 remains the only GC studied so far harboring a large fraction of fast rotating BSSs. All stars hotter than ~7800 K (regardless of the parent BSS sequence) show iron abundances larger than those measured from normal cluster stars, with a clearcut trend with the effective temperature. This behaviour suggests that particle trasport mechanisms driven by radiative levitation occur in the photosphere of these stars, as already observed for the BSSs in NGC 6397. Finally, 4 BSSs belonging to the red sequence (not affected by radiative levitation) show a strong depletion of [O/Fe], with respect to the abundance measured in Red Giant Branch and Horizontal Branch stars. This O-depletion is compatible with the chemical signature expected in BSSs formed by mass transfer processes in binary systems, in agreement with the mechanism proposed for the formation of BSSs in the red sequence.

description: By initiative of the SAPEA consortium, the Scientific Advice Mechanism will be delivering scientific policy advice on Transforming the Future of Ageing in Europe (the TFA report), to address the following question: what policies at the EU level could support the Member States in achieving inclusive, fair and sustainable systems of health and social care and promote the taking up of innovation for ageing societies? Based on the current international and European policy context, the available scientific evidence, and the expertise of an international and interdisciplinary working group, SAPEA will deliver a state-of-the-art Evidence Review Report (ERR) and provide science-based policy options. The final report is expected by summer 2019 and may inform the Commission’s policymaking in the field. A scoping paper was adopted on 27th April 2018 which summarises the areas that should be covered. A key milestone on the way to preparing the ERR and policy options was a one day expert workshop which took place on 07 December 2018 in Brussels, and brought together the SAPEA Working Group members and other experts with applied knowledge and experience - from industry, civil society, specialised agencies, etc. The aim of this workshop was to discuss and review the key findings of the TFA report, and to identify points to prioritise in the Scientific Opinion. The workshop participants discussed the draft report in terms of the feasibility and practical applicability of the recommendations made to transform the future of ageing. In total, there were 37 participants at the workshop with 15 external experts invited and selected based on their applied knowledge and experience in this field. The experts were provided with some guiding questions and the draft report in advance of the workshop to familiarise themselves with the content. They were asked to address questions that are raised in the draft report and areas of disagreement, relevant points that may have been omitted, and any inaccuracies that require correction and provide evidence which may have been missed in the literature presented. According to the rules of the meeting, this report is prepared in an anonymous and nonattributed style.

description: The possibility that extraterrestrial intelligences (ETIs) could be hostile to humanity has been raised as a reason to avoid even trying to contact ETIs. However, there is a distinct shortage of analytical discussion about the risks of an attack, perhaps because of an implicit premise that we cannot analyze the decision making of an alien civilization. This paper argues that we can draw some inferences from the history of the Cold War and nuclear deterrence in order to show that at least some attack scenarios are likely to be exaggerated. In particular, it would seem to be unlikely that the humanity would be attacked simply because it might, some time in the future, present a threat to the ETI. Even if communication proves to be difficult, rational decision-makers should avoid unprovoked attacks, because their success would be very difficult to assure. In general, it seems believable that interstellar conflicts between civilizations would remain rare. The findings advise caution for proposed interstellar missions, however, as starfaring capability itself might be seen as a threat. On the other hand, attempting to contact ETIs seems to be a relatively low-risk strategy: paranoid ETIs must also consider the possibility that the messages are a deception designed to lure out hostile civilizations and preemptively destroy them.

Αρχικά, παρουσιάζονται διάφορες πηγές ΑΠΕ και αναλύεται η λειτουργία των ανεμογεννητριών για την λύση των περιβαλλοντικών και ενεργειακών προβλημάτων.
Στην συνέχεια, θα πραγματοποιηθεί μία ανασκόπηση σε παρόμοιες εργασίες της βιβλιογραφίας στις οποίες αναλύεται και σχολιάζεται η ανάπτυξη μαθηματικών μοντέλων, η μεθοδολογία διαστασιολόγησης, καθώς και τα χαρακτηριστικά αποτελέσματα τους (διαστασιολόγηση αιολικών πάρκων, φωτοβολταικών σταθμών καθώς και υβριδικών συστημάτων ανεμογεννητριών-φωτοβολταικών).
Στη συνέχεια για την υλοποίηση του υπολογιστικού τμήματος της εργασίας παρουσιάζεται το μαθηματικό μοντέλο προσδιορισμού ισχύος των ανεμογεννητριών, που συγκρίνεται με τις εργοστασιακές τιμές της κάθε ανεμογεννήτριας (εξακρίβωση μοντέλου). Ακόμα, αναπτύσσεται ένας αλγόριθμος βελτιστοποίησης με στόχο τον προσδιορισμό του μεγέθους του αιολικού πάρκου ανάλογως με την ενεργειακή ζήτηση.
Στο κύριο μέρος της εργασίας πραγματοποιείται η βελτιστοποίηση για τρία διαφορετικά ενεργειακά προφίλ: ένα σπίτι, ένα σούπερ μάρκετ και ένα νοσοκομείο. Οι ανεμογεννήτριες που θα χρησιμοποιηθούν για την μελέτη είναι της τάξης των 600W, 800W, 1000W, 1500W και 2000W. Παρατηρήθηκε όμως, ότι αυτές οι ανεμογεννήτριες απαιτούν υψηλό αριθμό για να παρέχουν τα κατάλληλα ποσά ενέργειας στο σούπερ μάρκετ και στο νοσοκομείο οπότε αξιολογήθηκαν και ανεμογεννήτριες 0.5 ΜW,1 ΜW και 2.3 ΜW.

description: Current document reports on the development and validation of advanced practical models for describing force measuring devices used for the measurement of static, continuous forces in part A as well as dynamic forces in part B of the report. In the force measurement applications, the sensitivity curve of the force measuring devices determined in the calibration gives the traceability to national standards. The measurement uncertainty in an application is mainly affected by the sensitivity stability, the influence of temperature and other parasitic components. To capture these effects an advanced model for static and continuous forces was developed in part A which describes these influences especially in respect of their contribution to the measurement uncertainty. In contrast to the static calibration procedure, the dynamic calibration of the sensor has been always challenging because of several reasons such as the sophisticated nature of dynamic measurement, insufficient structural equipment, and parasitic effects which yield higher measurement uncertainty in comparison to static measurements and therefore inappropriate characterization of the force transducers. To close this knowledge gap in the dynamic calibration, the advanced model for dynamic forces was developed in part B. To consider the dynamic properties of force measuring devices the frequency dependency of the sensitivity and the influence of parasitic influences from temperature of the force measuring devices was considered and described. The target uncertainty is 1 % for up to 100 Hz and the target uncertainty is 2 % for higher frequency range from 100 Hz up to 1000 Hz.

description: This work presents accurate {\it ab initio} investigations of various spectroscopic properties of a few Li-like ions in presence of a plasma environment within the Debye screening potential. The coupled-cluster theory in the relativistic framework has been employed to compute ionization potentials, excitation energies, electric dipole oscillator strengths, and electric quadrupole transition probabilities of Li-like C$^{3+}$, N$^{4+}$, and O$^{5+}$ ions. The unretarded Breit interaction has been implemented to increase the accuracy of the calculations. The effects of ion density and temperature on the ionization potentials, excitation energies, electric dipole oscillator strengths, and electric quadrupole transition probabilities have been investigated in the plasma environment. It is found that the plasma screening leads to a sharp decrease in the ionization potential as the screening strength increases. With increasing strength, the oscillator strengths associated with 2$s ^{2}S_{1/2}$$\rightarrow2 p ^{2}P_{1/2, 3/2}$ transitions increase, whereas the transition probabilities associated with 3$d ^2D_{3/2, 5/2}$$\rightarrow2 s ^2S_{1/2}$ transitions decrease.

Publisher: name: Zenodo

description: The first essential step towards the production of a Scientific Opinion by the Group of Chief Scientific Advisors of the Commission’s Scientific Advice Mechanism (SAM) was the drafting of an evidence review report. This report is prepared by an international working group of the Science Advice for Policy by European Academies (SAPEA) consortium in response to a request from the European Commission for a rapid evidence review to inform the deliberations of itsGroup of Chief Scientific Advisors. Among other things, the Group has been asked to consider whether the current dual system for approval and authorisation of plant protection products (PPPs) in the EU could be rendered more effective, efficient and transparent, and if so, how this could be achieved. The SAPEA working group was asked to focus on methods and procedures for assessing potential harmful effects on human health from the use of plant protection products, and to report both on the current scientific state-of-the-art, and on the potential for future developments. Which methodology of arbitration could be used to solve issues arising from diverging assessments by different competent authorities based on the same science, or on a different assessment of uncertainties? To which extent would full alignment of risk assessment procedures solve the problem of different risk acceptance by different authorities? Seven independent working group experts reviewed the scientific evidence on the questions asked in the scoping paper.

description: The semantic Web service community develops efforts to bring semantics to Web service descriptions and allow automatic discovery and composition. However, there is no widespread adoption of such descriptions yet, because semantically defining Web services is highly complicated and costly. As a result, production Web services still rely on syntactic descriptions, key-word based discovery and predefined compositions. Hence, more advanced research on syntactic Web services is still ongoing. In this work we build syntactic composition Web services networks with three well known similarity metrics, namely Levenshtein, Jaro and Jaro-Winkler. We perform a comparative study on the metrics performance by studying the topological properties of networks built from a test collection of real-world descriptions. It appears Jaro-Winkler finds more appropriate similarities and can be used at higher thresholds. For lower thresholds, the Jaro metric would be preferable because it detect less irrelevant relationships.

description: The Berkeley Open Infrastructure for Network Computing (BOINC) is an open source client-server middleware system created to allow projects with large computational requirements, usually set in the scientific domain, to utilize a technically unlimited number of volunteer machines distributed over large physical distances. However various problems exist deploying applications over these heterogeneous machines using BOINC: applications must be ported to each machine architecture type, the project server must be trusted to supply authentic applications, applications that do not regularly checkpoint may lose execution progress upon volunteer machine termination and applications that have dependencies may find it difficult to run under BOINC. To solve such problems we introduce virtual BOINC, or V-BOINC, where virtual machines are used to run computations on volunteer machines. Application developers can then compile their applications on a single architecture, checkpointing issues are solved through virtualization API's and many security concerns are addressed via the virtual machine's sandbox environment. In this paper we focus on outlining a unique approach on how virtualization can be introduced into BOINC and demonstrate that V-BOINC offers acceptable computational performance when compared to regular BOINC. Finally we show that applications with dependencies can easily run under V-BOINC in turn increasing the computational potential volunteer computing offers to the general public and project developers.

description: Consumers are becoming increasingly concerned about the sustainability of their purchases. The coffee industry has been a leader in developing initiatives that promote the adoption of sustainable practices along the value chain. Labels on coffee packages that denote sustainable attributes are intended to inform the consumer and encourage sustainable consumption. The main objective of this study was to analyze consumers’ knowledge of, and preference for sustainable labels (Fairtrade, Organic USDA, Rain Forest Alliance, and 4C) on coffee in Honduras, a developing low-income and high-quality coffee exporting country. The study also evaluated the consumer’s visual attention to sustainable coffee labels. Data were collected using a questionnaire (including a choice experiment) from a sample of 450 consumers, as well as eye-tracking technology (a subsample of 65 consumers). Although Honduran coffee consumers have low levels of familiarity and knowledge about sustainable labels, they are willing to pay premiums for coffee with these labels (10% to 27% relative to average prices). Consumers pay more attention to the Organic USDA label, which is also the label with the highest willingness to pay value. Overall, the study’s results indicate that there is a domestic market for coffee produced sustainably in Honduras.
Photophoretic separation of metals and silicates: the formation of Mercury like planets and metal depletion in chondrites

description: Mercury's high uncompressed mass density suggests that the planet is largely composed of iron, either bound within metal (mainly Fe-Ni), or iron sulfide. Recent results from the MESSENGER mission to Mercury imply a low temperature history of the planet which questions the standard formation models of impact mantle stripping or evaporation to explain the high metal content. Like Mercury, the two smallest extrasolar rocky planets with mass and size determination, CoRoT-7b and Kepler-10b, were found to be of high density. As they orbit close to their host stars this indicates that iron rich inner planets might not be a nuisance of the solar system but be part of a general scheme of planet formation. From undifferentiated chondrites it is also known that the metal to silicate ratio is highly variable which must be ascribed to pre-planetary fractionation processes. Due to this fractionation most chondritic parent bodies - most of them originated in the asteroid belt - are depleted in iron relative to average solar system abundances. The astrophysical processes leading to metal silicate fractionation in the solar nebula are essentially unknown. Here, we consider photophoretic forces. As these forces particularly act on irradiated solids, they might play a significant role for the composition of planetesimals forming at the inner edge of protoplanetary discs. Photophoresis can separate high thermal conductivity materials (iron) from lower thermal conductivity solids (silicate). We suggest that the silicates are preferentially pushed into the optical thick disk. Subsequent planetesimal formation at the edge moving outwards leads to metal rich planetesimals close to the star and metal depleted planetesimals further out in the nebula.
