description: Microalgae are said to have huge potential as a renewable resource for biofuels. To reduce the impact produced by conventional sources of energy, sustainable sources become more and more important. However, in order to operate an algae production site profitable, more applications of algal biomass should be taken into account. One of the biggest environmental contributions most of us could make is by far much less communicated than biofuels: human nutrition. This is especially true regarding the amount of meat, which is produced and connected to the environmental damage that goes hand in hand with it. The production of food can also be an interesting topic for microalgae. Some claim that algae can solve several challenges at the same time: oil for human nutrition (and therefore of high value, e.g. omega-3 fatty acids) and oil of low value, e.g. for biofuels. The rest of the algae cell wall could be used as animal food, e.g. fish food. Is this possible in a sustainable and economic way, and can algae help to solve some of the world-s main challenges ahead? This Master Thesis should help to find the answer. The major objective is to explain which production technologies combined with suitable algae strains can be used for different applications: biofuels, human nutrition supplements, cosmetics, and animal food. Therefore, this master thesis will show the possibilities and requirements of symbiotic production possibilities of algal biomass, in order to make algae biofuels commercially feasible.

subject: F30

description: This article considers first the early history of the Australian money market. A serious market first began to emerge in the 1950s, catalysed by stock and share brokers. However it was not until 1959 that lender-of-last-resort facilities became available to ensure market liquidity for official market makers. Over recent years the greatest growth has been in the unofficial sectors. The article reviews the role and nature of participants and the instruments traded and asks whether the demise of the official market makers is imminent. JEL: F30

description: In this paper, we have studied the effect of doping of ZnO and MgO nanoparticles (NPs) in 4-(trans-4-n-hexylcyclo-hexyl) isothiocyanatobenzoate. A thorough comparison of dielectric properties, optoelectronic properties, and calorimetric phase transition properties has been done for MgO and ZnO NP doped LC. We prepare their homogenous mixture of MgO and ZnO NPs in toluene and transfer into cells made of glass and Indium Tin-Oxide (ITO) coated glass. The observed microstructures in the hybrid system can be classified into three main categories: grain like structures formed by aggregation of smaller size MgO nanoparticles while liquid crystal molecules anchor over the surfaces of nanoparticles, the grtu grain-like structures further integrate to form inorganic polymeric type of honeycomb-like mesostructures in presence of glass surface, and flower-like clusters of MgO nanoparticles on ITO surface. The smaller size nanoparticles can maintain the energy balance by allowing the anchoring of liquid crystal molecules over their surfaces whereas the larger size nanoparticles cannot compromise or maintain the energy balance with the liquid crystal molecules and are separated out to nucleate and form bigger size nanoaggregate or clusters. The energy preference of the substrate and nanoparticle's surface to liquid crystal molecules plays an important role in the formation of different types of hierarchical nano- and microstructures. We account the reasons for the formation of nano and micro scale hierarchical structures on the basis of the competition between the forces: NP-NP, LC-LC, NP-LC, Glass/ITO-NP, and Glass/ITO-LC interactions. We observed a considerable change in the dielectric properties, transition temperature, bandgap, and other parameters of LC molecules when MgO NPs are doped, but a minor change occurs when ZnO NPs are doped in LC.

description: We report a new scheme to create weakly bound Cs$_2$ molecules from an atomic Bose-Einstein condensate. The method is based on switching the magnetic field to a narrow Feshbach resonance and yields a high atom-molecule conversion efficiency of more than 30%, a factor of three higher than obtained with conventional magnetic-field ramps. The Cs$_2$ molecules are created in a single $g$-wave rotational quantum state. The observed dependence of the conversion efficiency on the magnetic field and atom density shows scattering processes beyond two-body coupling to occur in the vicinity of the Feshbach resonance.

Vulnerability of marine fishes to fishing : from global overview to the northern South China Sea
Creators: name: Cheung, Wai Lung
Publisher: name: University of British Columbia
Year: 2011

description: Fishing has become a major conservation threat to marine fishes. Effective conservation of threatened species requires timely conservation risk assessment and formulation of socio-economically viable policies. A fuzzy logic expert system is developed to predict the intrinsic vulnerability and depletion risk of marine fishes to fishing. Firstly, the expert system predicts intrinsic vulnerability (i.e., fishes' inherent ability to withstand fishing mortality) from simple parameters of life history and ecology. Secondly, the system predicts the relative depletion risk of marine fishes from their intrinsic vulnerability and exploitation status inferred from catch time-series. These methods reveal the increasing dominance in global catches by fishes with low intrinsic vulnerability, particularly those in coral reefs. The opposite trend is observed in seamounts where species are highly vulnerable to fishing and are increasingly being exploited and serially depleted in recent years. Moreover, risk of population depletion increased greatly from the 1970s to 2000s. Among all extant marine fishes, 10 to 20% are predicted to have high depletion risk. In the northern South China Sea (NSCS), relative abundance of 15 out of the 17 studied taxa declines by over 70% in 15 years. The rate of decline is con-elated with the intrinsic vulnerability of the taxa. Using the Ecopath with Ecosim modelling approach, the structures of the NSCS ecosystem in the 1970s and 2000s are reconstructed and compared. The models show that the NSCS ecosystem has chanced from being demersal-dominated to pelagic-dominated, with a large decline in overall biomass and decrease in ecosystem maturity. Primary production is largely utilized by the fisheries compared to some 30 years ago when primary production was mainly utilized by marine fauna. The model is able to emulate the changes of observed relative abundance of commercial taxa. Using Ecosim, trade-off between conservation status (indicated by a depletion index) and economic benefits is identified as convex-shaped. The 2000s ecosystem appears sub-optimal ecologically and economically, thus improvement in conservation and economic benefits can be achieved simultaneously. However, the resulting social problems due to loss of fishing-related jobs need to be addressed first. Thus, developing viable alternative livelihoods for fishers is a priority to meet conservation and economic objectives.

A global analysis of the sustainability of marine aquaculture
Creators: name: Trujillo, Pablo
Publisher: name: University of British Columbia
Year: 2011

description: Following a review of the history and main characteristics of mariculture, a global assessment of its sustainability over the 10 year period from 1994 to 2003 was performed, which suggests that sustainability is low. The assessment is based on 13 indicators covering ecological, economic and social aspects of the industry and involving 60 countries and 86 species. The suite of indicators were based on a set of criteria meant to be independent of areas, species and time, so that they have wide application and will be applicable for years to come. The indicators used in the analyses proved to be effective in differentiating levels of sustainability between countries and species and provided a benchmark on which to gauge progress within the industry in the coming decades. A single mariculture sustainability index (MSI), ranging between 1 and 10, was derived by combining the 13 indicators weighted by production to analyze differences between countries and species, and to compare the MSI with other indicators such as the environmental sustainability index (ESI) and the human development index (HDI). The highest ranking countries for sustainable mariculture are Germany, the Netherlands, Spain, Japan and South Korea. In these countries, the common factor is farming (1) native species, (2) low trophic level species, (3) under non-intensive conditions, (4) for domestic consumption. The lowest ranking countries were Guatemala, Cambodia, Bangladesh, Honduras and Myanmar. The common factor in these countries is the culture of (1) non-native species, (2) higher trophic level species, (3) farmed intensively, and (4) destined for export, often to countries ranking high for mariculture sustainability. The highest ranking species on the sustainability scale were mollusks, specifically bivalves, i.e., blue mussels and cupped oysters. For finfish, the highest ranking taxa were Atlantic halibut, Spotted wolfish and European eel. The lowest ranking species belonged to the crustacean groups, specifically prawns and shrimp. Many of the most valuable groups such as shrimp and salmon were among the lowest scoring species in both developing and developed countries. The global average MSI score was 5.1 based on 361 cases. Based on this analyses, it is suggested that the industry is at the cross-roads of sustainability. There are a number of options for the industry to ensure it is sustainable over the long-term, including the implementation of best management practices, economic incentives and consumer awareness, expressed as a willingness to pay higher prices for sustainability. The results of this study provide the framework, indicators and baseline data on which to assess the sustainability of mariculture at global and regional levels, as well as across species. The MSI developed in this study can be used to generate globally, robust rankings of countries and taxa in terms of their sustainability.
title: Connecting children with their family of origin : a study of contact arrangements for fostered children in Malta
Creators: name: Galea-Seychell, Olivia
Publisher: name: The Open University
Year: 2011

description: Maintaining links with the family of origin is significant to children's welfare. This thesis studies contact arrangements between children in foster care and their family of origin. Contact with birth parents, siblings and the extended family is explored. A survey of social work case files is carried out. The survey of 136 fostered children reports that children live in long term care. Same sibling placement is uncommon. Children are most frequently in contact with siblings, followed by contact with the mother. Contact with the father is associated negatively with educational attainment, whilst contact with the mother is associated with emotional/behavioural concerns. As a result of the survey's findings, this thesis develops an intensive study of contact. Twenty two children residing in foster care and their 21 foster carers are interviewed. Pictorial vignettes and visual spatial techniques are administered to children. Through these techniques children's views, experiences and wishes of contact are reported. A questionnaire and an interview are also administered to foster carers. Children view contact favourably with siblings and the extended family. Negative emotions are found when contact with parents is discussed. Most children have face-to-face contact with siblings. They also wish to have more contact with siblings. Contact with the extended family such as grandparents is non-threatening. Foster carers hold ambivalent views about contact. Whilst promoting contact, they show reluctance towards children's contact with parents and the extended family. The study reports that both children and foster carers are involved, by practitioners, in contact issues. Moreover, contact is identified as significant to children's identity development. A practice model of contact is discussed in the conclusion of this thesis.

description: One tradition in international economics explains international trade as a phenomenon caused by differing national comparative advantages arising from different states of development. This approach leads to the conclusion that under a catching-up hypothesis the amount of trade might be expected to diminish over time. The authors analyse trade between Sweden and the United States, emphasising the R&D component of trade. They conclude that specialisation has occurred in the R&D intensity of goods being traded and that this has increased the scope for trade. JEL: F10

Double-Chooz: a search for Theta13
Creators: name: Lasserre, Th.
Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: The Double-Chooz experiment goal is to search for a non-vanishing value of the Theta13 neutrino mixing angle. This is the last step to accomplish prior moving towards a new era of precision measurements in the lepton sector. The current best constraint on the third mixing angle comes from the CHOOZ reactor neutrino experiment $\sin(2θ_{13})^{2}<0.2$ (90% C.L., $Δm_{atm}^{2}=2.0$ eV$^{2}$). Double-Chooz will explore the range of $\sin(2θ_{13})^{2}$ from 0.2 to 0.03-0.02, within three years of data taking. The improvement of the CHOOZ result requires an increase in the statistics, a reduction of the systematic error below one percent, and a careful control of the backgrounds. Therefore, Double-Chooz will use two identical detectors, one at 150 m and another at 1.05 km distance from the Chooz nuclear cores. In addition, we will to use the near detector as a ``state of the art'' prototype to investigate the potential of neutrinos for monitoring the civil nuclear power plants. The plan is to start operation with two detectors in 2008, and to reach a sensitivity sin$^{2}$$(2θ_{13})$ of 0.05 in 2009, and 0.03-0.02 in 2011.

description: The MacCulloch field lies in Block 15/24b in the Central North Sea. The field has been on production since 1997. The primary reservoir is Lower Palaeocene turbidite sandstones of the Upper Balmoral Sandstone unit in the Lower Palaeocene Lista Formation. It is connected to a large aquifer in the underlying Lower Balmoral Sandstone unit. The field is made up of a number of individual turbidite flows predominantly characterised by clean, high porosity and permeability, high net/gross sandstones. These discrete depositional units can be distinguished on the seismic data and examination of the time-lapse response of these units shows that they have acted as a primary control on the depletion of the field. The objective of the core display is to show differences between individual massive reservoir sand units from different flow episodes and illustrate some of the more minor reservoir facies encountered in possible overbank deposits or margins to individual flow packages.
Effect of out-of-plane acoustic phonons on the thermal transport properties of graphene

Year: 2024
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: The lattice thermal conductivity of graphene is evaluated using a microscopic model that takes into account the lattice's discrete nature and the phonon dispersion relation within the Brillouin zone. The Boltzmann transport equation is solved iteratively within the framework of three-phonon interactions without taking into account the four-phonon scattering process. The Umklapp and normal collisions are treated rigorously, thereby avoiding relaxation-time and long-wavelength approximations. The mechanisms of the failures of these approximations in predicting the thermal transport properties are discussed. Evaluation of the thermal conductivity is performed at different temperatures and frequencies and in different crystallite sizes. Reasonably good agreement with the experimental data is obtained. The calculation reveals a critical role of out-of-plane acoustic phonons in determining the thermal conductivity. The out-of-plane acoustic phonons contribute greatly and the longitudinal and transverse acoustic phonons make small contributions over a wide range of temperatures and frequencies. The out-of-plane acoustic phonons dominate the thermal conductivity due to their high density of states and restrictions governing the anharmonic phonon scattering. The selection rule severely restricts the phase space for out-of-plane phonon scattering due to reflection symmetry. The optical phonon contribution cannot be neglected at higher temperatures. Both Umklapp and normal processes must be taken into account in order to predict the phonon transport properties accurately.

Polaron formation as origin of unconventional isotope effects in cuprate superconductors

Year: 2004
Subjects: subject: Superconductivity (cond-mat.supr-con)

description: Various unconventional isotope effects have been reported in high-temperature superconducting copper oxides which are beyond the scheme of BCS theory. Their origin is investigated within polaron theory which leads to a renormalization of the single particle energies and introduces a level shift here. It is found that the exponential squeezing of the second nearest neighbour hopping integral carries the correct isotope effect on the superconducting transition temperature Tc, as well as the one on the penetration depth. The average superconducting gap is predicted to have an isotope effect comparable to the one on the penetration depth. The results imply that the coupling of the electronic degrees of freedom to the Jahn-Teller Q2-type mode is the origin of these isotope effects.

description: Some economists suggest that macroeconomic theory is incomplete because it has neglected to construct a model of instability. The author contends that a theory of depression must provide information on an economy's ability to resist depressions most of the time, and yet have an innate capacity to slide either slowly or rapidly into them periodically; the role of financial crisis and the ability of the economy to revive must also be explained. The author builds a model that exhibits these capacities and suggests that flight from the dollar may present a great threat to world economic stability. JEL: E17, G01

description: We address the properties of continuous-time quantum walks with Hamiltonians of the form $\mathcal{H}= L + λL^2$, being $L$ the Laplacian matrix of the underlying graph and being the perturbation $λL^2$ motivated by its potential use to introduce next-nearest-neighbor hopping. We consider cycle, complete, and star graphs because paradigmatic models with low/high connectivity and/or symmetry. First, we investigate the dynamics of an initially localized walker. Then, we devote attention to estimating the perturbation parameter $λ$ using only a snapshot of the walker dynamics. Our analysis shows that a walker on a cycle graph is spreading ballistically independently of the perturbation, whereas on complete and star graphs one observes perturbation-dependent revivals and strong localization phenomena. Concerning the estimation of the perturbation, we determine the walker preparations and the simple graphs that maximize the Quantum Fisher Information. We also assess the performance of position measurement, which turns out to be optimal, or nearly optimal, in several situations of interest. Besides fundamental interest, our study may find applications in designing enhanced algorithms on graphs.

description: Temperature measurements of dielectric permittivity are performed for nonstoichiometric ferroelectric lead germanate Pb$_{4.95}$Ge$_3$O$_{11}$ and multiferroic solid solution [N(C$_2$H$_5$)$_4$]$_2$CoClBr$_3$. Unlike the heat capacity data, the analysis of the dielectric permittivity of ferroics is usually performed at the assumption that the dielectric "background" is negligible compared with its critical part. In this work we quantitatively interpret the dielectric properties of the single crystals mentioned above and the appropriate literature data for multiferroic Sr$_2$IrO$_4$ crystals, using generalized Curie-Weiss formulas that combine corrections due to a nonlinear temperature-dependent dielectric background, a modified critical index of electric susceptibility, and a diffuse character of phase transition. We argue that taking account of the temperature dependent dielectric background can improve notably the quantitative analysis of PTs for a number of classes of the ferroic materials.

description: The topcolor-assisted technicolor (TC2) theory predicts tree-level flavor-changing neutral-current (FCNC) top quark Yukawa couplings with top-pions. Such FCNC interactions will induce like-sign top quark pair productions at CERN Large Hadron Collider (LHC). While these rare productions are far below the observable level in the Standard Model and other popular new physics models such as the Minimal Supersymmetric Model, we find that in a sound part of parameter space the TC2 model can enhance the production cross sections to several tens of fb and thus may be observable at the LHC due to rather low backgrounds. Searching for these productions at the LHC will serve as an excellent probe for the TC2 model.

Sedimentary evolution of the Lower Clair Group, Devonian, west of Shetland: climate and sediment supply controls on fluvial, aeolian and lacustrine deposition
Creators: name: G.J. NICHOLS
Publisher: name: Geological Society of London

Subjects: subject: Geology

description: Sandstone units in the Devonian Lower Clair Group vary from (a) thick, wellsorted, medium sands deposited by aeolian processes, to (b) amalgamated fluvial channel deposits of coarser sand, to (c) thin sheets of fine sand deposited in floodplain or shallow lake settings. The six lithostratigraphic subdivisions (units I to VI) of the group are differentiated by changes in the predominance of fluvial, aeolian and lacustrine facies which are in turn controlled by sediment supply and climate. During periods of high sediment supply and relatively humid climate (Units II, IV and V), fluvial conditions dominated in the form of sandy to pebbly fluvial distributary systems on the alluvial plain. The sand body characteristics vary from stacked, coarse channel fills deposited by high energy braided rivers (Unit II) to decimetre sand sheets interpreted as the deposits of poorly channelised flow at the margins of the terminal fan (Unit V). At times of relative aridity, the fluvial system retreated and aeolian reworking resulted in extensive sheets of well-sorted sands deposited as dunes or more commonly on sand-flats (Unit III). Periods of wetter climate and reduced clastic input resulted in lacustrine facies fed by rivers which formed lake deltas which were coarse, fan deltas (Unit I) of fine-grained deltas (Unit VI). The Devonian Clair Basin is an example of deposition in a basin of internal drainage which was predominantly controlled by climatic and sediment supply variations: a predictive model for sand body character and distribution can be developed using an understanding of these controls on the depositional systems.

The main part of the paper assesses the economic effect for the different power plant owners participating in the Virtual Power Plant. The economic assessment with regards to different promotion strategies will be done on the basis of energyPRO simulations for the Virtual Power Plant in combination with a Vanadium Redox-Flow-battery. The battery will be defined according to the technical requirements for the different promotion strategies especially for participating on the balancing market for offering Tertiary Control Reserve. The findings show that participation on the balancing market for trading Tertiary Control Reserve for the Virtual Power Plant isn't economic viable so far due to high costs of storage systems and the relatively low revenues on the balancing energy market. Also the necessary cost reductions will be defined for the Redox-Flow battery according to the Net present value calculation over the life time. In addition estimations for the participation on other parts of the balancing market will be given.

description: The molecular dynamics simulations were used to obtain the radius of gyration of real ring polymer chains with different topological structures consisting of 360 monomers. We focus on the entropic force which is exerted by a dilute solution of ring polymer chains of different topological structures with the excluded volume interaction (EVI) in a good solvent on the confining parallel walls of a slit geometry. We consider mixed boundary conditions of one repulsive wall and the other one at the adsorption threshold. The obtained molecular dynamics simulation results for a wide slit region demonstrate a qualitative agreement with previous analytical results for ideal ring polymers. These results could lead to interesting potential applications in materials engineering and improve understanding of some biological processes suggested in the paper. Additionally, they could be applied in micro- and nano-electromechanical devices (MEMS and NEMS) in order to reduce the static friction.

description: We investigate the influence of the momentum cutoff function on the field-dependent nonperturbative renormalization group flows for the three-dimensional Ising model, up to the second order of the derivative expansion. We show that, even when dealing with the full functional dependence of the renormalization functions, the accuracy of the critical exponents can be simply optimized, through the principle of minimal sensitivity, which yields $ν= 0.628$ and $η= 0.044$.

description: The development of methods of seismic imaging beneath basalt is still hindered by a lack of knowledge about the elastic properties of basaltic sequences and the degree of three-dimensional heterogeneity. The SeiFaBa project (2002- 2005) is funded by the Sindri Group as part of the programmes for licensees within the Faroese area and will address these issues. The first year included drilling of a new 700-m deep well, Glyvursnes-1, near Tórshavn with full core, reaming of the existing 660 m deep Vestmanna-1 well farther north, and the acquisition of a wide range of wireline logs in both wells. The two wells represent almost half of the exposed lava sequence and are central to a number of co-ordinated experiments. These are targeted at creating firm data-derived models for seismic wave propagation through basalt by combining detailed analysis at core, log and seismic scales. After initial tests in 2002 the main part of the seismic programme was carried out June to September 2003. The work was centred on Glyvursnes-1 and included both VSP, offset-VSP and surface seismic experiments. Detailed studies of well logs and core material from the above and other wells have been initiated. The aim is to better understand the sonic response of basalt lavas in terms of physical and compositional properties and thus also seismic signatures of flood basalt successions.
Comptonization in the vicinity of black hole horizon

description: Using a Monte Carlo method, we derive spectra arising from Comptonization taking place close to a Kerr black hole. We consider a model consisting of a hot thermal corona Comptonizing seed photons emitted by a cold accretion disc. We find that general relativistic effects are crucial for the emerging spectra in models which involve significant contribution of radiation produced in the black hole ergosphere. Due to this contribution, spectra of hard X-ray emission produced in the vicinity of a rapidly rotating black hole strongly depend on the inclination of the line of sight, with larger inclinations corresponding to harder spectra. Remarkably, such anisotropy could be responsible for properties of the X-ray spectra of Seyfert galaxies, which appear to be intrinsically harder in type 2 objects than in type 1, as reported recently.

description: Selected sections from four RSG consortium boreholes are displayed. These serve to highlight some of the key stratigraphic units and contacts along the eastern margin of the Rockall Basin. The cores were acquired using the MV Bucentaur in 1999 in a bid to constrain the stratigraphic evolution of the basin by coring Mesozoic and Tertiary stratigraphy tied via high resolution site survey seismic grids to regional industry seismic lines. Borehole 11/20-sb01 on the Erris High cored the flanks of a Palaeogene (?), shallow water tuff cone, and two core sections illustrate the volcaniclastic facies and evidence for post-eruption injection of the cone by soft carbonate sediment. Borehole 16/28-sb01 was drilled on the slopes north of the Porcupine High, and selected cored sections illustrate the basalt in which the hole terminated (a flow or a sill?), overlain by a thin Maastrichtian or older sandy grainstone. This is truncated by a subtle but significant unconformity, above which a deepening upward Eocene section is preserved. Borehole 83/20-sb01 on the western flank of the Porcupine High above the Bróna Basin reached the Jurassic, which is here overlain by a diverse Cretaceous section recording an upward evolution from shallow to deeper water ('brownsand' to 'greensand' to chalkey marl). A major phosphatised and Mn-impregnated surface cuts into the Cretaceous (the C30 surface?) and is onlapped by Miocene slope sediments. Borehole 83/24-sb02 lies SW of 83/20-sb01 deeper on the slope. It also cored a Cretaceous section (here the 'brownsand' unit) siting unconformably on an older Jurassic and/or Carboniferous interval. At this site, the Cretaceous is overlain by Eocene pelagic carbonates that were removed by erosion up dip.

Australian Research Data Commons

description: This is the co-design framework for designing the HASS and Indigenous Research Data Commons, an initative of the Australian Research Data Commons (ARDC).

In collaboration with Indigenous Australians, the research community, industry and government, the Humanities, Arts and Social Sciences and Indigenous Research Data Commons (HASS and Indigenous RDC) is harnessing research data to enhance Australian social and cultural wellbeing, and help Australia understand and preserve our culture, history and heritage.

Investment in the HASS and Indigenous RDC will be made based on opportunities identified in partnership with stakeholders in the humanities, arts, social sciences and Indigenous research communities, and the broader groups who contribute to and benefit from that research. We will seek to develop infrastructure that creates the greatest impact for research and researchers by co-designing that infrastructure with the people who will benefit from it.

Our consultation and co-design processes are based on established methods such as the TACSI Co-Design Framework. Development of our co-investment activities will follow the steps of:

Problem Identification 

Project Shaping

Project Planning

Endorsement.

The way that each step is implemented will vary depending on the scale, complexity and timeline of the activity.

Are bank’s speculative profits at the expense of traders?

description: Banks extract large profits through speculative trading on the foreign exchange markets and some authors have argued that banks are the winners and that the traders of goods and services are the losers in this game of foreign exchange dealing. The author argues that banks earn a return through providing a service of smoothing exchange rates over time and that this represents a benefit to international traders in other markets. It is argued that the banks' speculative trade raises economic efficiency in the real economy by reducing the volatility of exchange rates. JEL: F31, G21

Constraints on a mixed inflaton and curvaton scenario for the generation of the curvature perturbation

description: We consider a supersymmetric grand unified model which naturally solves the strong CP and mu problems via a Peccei-Quinn symmetry and leads to the standard realization of hybrid inflation. We show that the Peccei-Quinn field of this model can act as curvaton. In contrast to the standard curvaton hypothesis, both the inflaton and the curvaton contribute to the total curvature perturbation. The model predicts an isocurvature perturbation too which has mixed correlation with the adiabatic one. The cold dark matter of the universe is mostly constituted by axions plus a small amount of lightest sparticles. The predictions of the model are confronted with the Wilkinson microwave anisotropy probe and other cosmic microwave background radiation data. We analyze two representative choices of parameters and derive bounds on the curvaton contribution to the adiabatic perturbation. We find that, for the choice which provides the best fitting of the data, the curvaton contribution to the adiabatic amplitude must be smaller than about 67% (at 95% confidence level). The best-fit power spectra are dominated by the adiabatic part of the inflaton contribution. We use Bayesian model comparison to show that this choice of parameters is disfavored with respect to the pure inflaton scale-invariant case with odds of 50 to 1. For the second choice of parameters, the adiabatic mode is dominated by the curvaton, but this choice is strongly disfavored relative to the pure inflaton scale-invariant case (with odds of 10^7 to 1). We conclude that in the present framework the perturbations must be dominated by the adiabatic component from the inflaton.
