description: A continued dominance of traditional retail outlets is observed despite rapid modern retail expansion. To examine this trend in a predominantly agricultural area, a case study of Tagum City is conducted where developments in the retail food industry are presented and the determinants of retail outlet choice for fresh fruits and vegetables are identified. Multinomial and binary logit models were estimated to analyze the responses of 200 consumer-respondents among urban villages in Tagum City from 2011 to 2012. These were supplemented by key informant interviews. The results suggest that there is a potential for further expansion of the modern retail chain in Tagum City despite consumers’ preference for traditional retail outlets. The top retail outlet attributes for fruit and vegetable buyers are convenience of location, price, product quality, and speed of service. These findings have implications on consumer welfare, retail competition, and smallholder farmers.

description: A general class of gauges for open string field theory, for which the gauge fixing condition is given by linear equations with respect to string field, is investigated in detail. This class of gauges includes almost all known ones like Siegel gauge and its various extensions such as a-gauges proposed by the present authors as well as Schnabl gauge and linear b-gauges. A general form of propagators is determined and their common features are analyzed. A consistent procedure for calculating the amplitudes is given. Gauge independence of the on-shell physical amplitudes is explicitly shown.

description: We generalize the notion of and results on maximal proper quadratic modules from commutative unital rings to $\ast$-rings and discuss the relation of this generalization to recent developments in noncommutative real algebraic geometry. The simplest example of a maximal proper quadratic module is the cone of all positive semidefinite complex matrices of a fixed dimension. We show that the support of a maximal proper quadratic module is the symmetric part of a prime $\ast$-ideal, that every maximal proper quadratic module in a Noetherian $\ast$-ring comes from a maximal proper quadratic module in a simple artinian ring with involution and that maximal proper quadratic modules satisfy an intersection theorem. As an application we obtain the following extension of Schm\" udgen's Strict Positivstellensatz for the Weyl algebra: Let $c$ be an element of the Weyl algebra $\mathcal{W}(d)$ which is not negative semidefinite in the Schr\" odinger representation. It is shown that under some conditions there exists an integer $k$ and elements $r_1,...,r_k \in \mathcal{W}(d)$ such that $\sum_{j=1}^k r_j c r_j^\ast$ is a finite sum of hermitian squares. This result is not a proper generalization however because we don't have the bound $k \le d$.

On disc protoplanet interactions in a non-barotropic disc with thermal diffusion

description: We study the disc planet interactions of low-mass protoplanets embedded in a circumstellar disc. We extend the standard theory of planet migration from the usual locally isothermal assumption to include non-barotropic effects, focusing on the validity of linear theory. We compared solutions of the linear equations with results from non-linear hydrodynamic simulations, where in both cases we adopted a background entropy gradient and solved the energy equation. We show that the migration behavior of embedded planets depends critically on the background radial entropy gradient in the disc. The presence of such a gradient not only changes the corotation torque on the planet, but also always guarantees a departure from linear behavior, which gives a singular density response at corotation, in the absence of thermal or viscous diffusion. A negative entropy gradient tends to give rise to positive, non-linear corotation torques apparently produced as material executes horseshoe turns at approximately constant entropy. These torques have no counterpart in linear theory, but can be strong enough to push the planet outwards until saturation starts to occur after a horseshoe libration period. Increased thermal diffusion acts to reduce these non-linear torques, but, at the same time, it can help to prevent their saturation. In combination with a small kinematic viscosity that is able to maintain a smooth density profile the positive torque could be sustained.

description: We report a novel approach to the nanostructuring the In2S3 thin films surface grown by thermal evaporation technique on glass substrates. Our approach is based on using argon inductively coupled plasma sputtering technique with 20-200 eV ion energy. X-ray measurements were performed to confirm the crystallinity and phase composition of the In2S3 films. Morphology and chemical composition of the ﬁlms were studied using scanning electron microscopy and energy dispersive x-ray spectroscopy, respectively. The optical properties were investigated by measuring the optical transmittance and reflection spectra. The formation of indium droplets with sizes 10-300 nm and surface density 8∙108 - 9∙1011 cm-2 on the In2S3 films surface during plasma treatment was described.

description: The vacuum of Yang-Mills theory contains singular stringlike objects identified with center (magnetic) vortices. Percolation of magnetic vortices is known to be responsible for the color confinement in the low-temperature phase of the theory. In our work we study properties of the vortices at finite temperature using lattice simulations of SU(2) gauge theory. We show that magnetic vortices provide a numerically large contribution to thermodynamic quantities of the gluon plasma in Yang-Mills theory. In particular, we observe that in the deconfinement phase at temperatures T_c < T < 3 T_c the magnetic component of the gluon plasma produces a negative (ghostlike) contribution to the anomaly of the energy-momentum tensor. In the confinement phase the vortex contribution is positive. The thermodynamical significance of the magnetic objects allows us to suggest that the quark-gluon plasma may contain a developed network of magnetic flux tubes. The existence of the vortex network may lead to observable effects in the quark-gluon plasma because the chromomagnetic field of the vortices should scatter and drag quarks.

description: A commutative loop is Jordan if it satisfies the identity $x^2 (y x) = (x^2 y) x$. Using an amalgam construction and its generalizations, we prove that a nonassociative Jordan loop of order $n$ exists if and only if $n\geq 6$ and $n\neq 9$. We also consider whether powers of elements in Jordan loops are well-defined, and we construct an infinite family of finite simple nonassociative Jordan loops.

description: This paper aims to demonstrate the important role of cooperatives in the provision and delivery of potable water to a community of households based on evidence from a case study of Talaga Barangay Water Service Cooperative (TBWSC) in Tanauan, Batangas. TBWSC is a water service type of cooperative that successfully provides its members with access to potable water. The case shows how social capital works in addressing a common need. Particularly, it presents the collaborative partnership between the government and the cooperative in implementing a waterworks project. The factors contributing to the success of water service delivery are the felt need of the community to have potable water, access to financial and human resources, presence and commitment of the cooperative and government as collaborating groups, and the participatory approach to organization and management of the cooperative in providing potable water to the community. As a water service cooperative, TBWSC is successful based on its financial performance and achievement of its mission and goals.

description: 36th European Photovoltaic Solar Energy Conference and Exhibition; 522-526
description: The passivation properties of the hydrogenated amorphous silicon oxide (a-SiOx:H) film with the thin thickness applied to the Si-based heterojunction solar cells were investigate. It is confirmed that the ~2nm thickness of the a-SiOx:H film is enough to obtain the satisfactory effective lifetime of excess minority carrier using the structure passivated by the a-SiOx:H/n-type a-Si:H bilayer, although the at least 3nm overlayer of a-Si:H is necessary in the emitter side to probably protect the a-SiOx:H passivation film against the influence of p-layer deposition. The Cody gap estimated from the spectroscopic ellipsometry measurement showed that the optical bandgap of this ~2nm-thick a-SiOx:H film is narrower than that of the bulk state, which was suggested probably to be resulted from the non-steep changes of hydrogen content and from the existence of the partially epitaxial growth and/or nanocrystallized structure film at the a-SiOx:H/c-Si interface by the measurements of high resolution Rutherford backscattering spectrometry and high resolution elastic recoil detection analysis. These high passivation quality and comparably narrow bandgap of the a-SiOx:H film at the thin thickness should be beneficial to obtain high Voc and FF.

description: Transverse momentum spectra of Lambda and K0Short particles are presented for Cu+Cu sqrt(s_NN) = 200 GeV collisions observed at STAR, and compared to Au+Au measurements at the same energy. For both systems, a number of observables are shown to increase at mid-rapidity (|y| < 0.5) with increasing centrality. These are the integrated Lambda and K0Short yields, the integrated Lambda and K0Short yields per participating nucleon, and mid-pT (1 GeV/c -> 4.5 GeV/c) Lambda/KK0Short ratios. The RCP ratio is found to be higher for the Lambda yields at mid-pT compared to the K0Short yields for both the Cu+Cu and Au+Au data. In contrast, when similar numbers of participating nucleons are considered for the Cu+Cu and Au+Au data, an indication of increased bulk strangeness production and a higher mid-pT (1 -> 4.5 GeV/c) Lambda/K0Short ratio are found, for Cu+Cu.

description: High time resolution observations of PSR B0906-49 (or PSR J0908-4913) over a wide range of frequencies have enabled us to determine the geometry and beam shape of the pulsar. We have used the position angle traverse to determine highly-constrained solutions to the rotating vector model which show conclusively that PSR B0906-49 is an orthogonal rotator. The accuracy obtained in measuring the geometry is unprecedented. This may allow tests of high-energy emission models, should the pulsar be detected with GLAST. Although the impact parameter, beta, appears to be frequency dependent, we have shown that this is due to the effect of interstellar scattering. As a result, this pulsar provides some of the strongest evidence yet that the position angle swing is indeed related to a geometrical origin, at least for non-recycled pulsars. We show that the beam structures of the main pulse and interpulse in PSR B0906-49 are remarkably similar. The emission comes from a height of ~230 km and is consistent with originating in a patchy cone located about half way to the last open field lines. The rotation axis and direction of motion of the pulsar appear to be aligned.

description: This paper includes an extended review of Moshe Idel’s Mircea Eliade: From Magic to Myth (New York: Peter Lang, 2014) through a triple analysis of Eliade’s early literary, epistolary, and academic texts. The paper examines Idel’s analysis of some important themes in Eliade’s research, such as his shift from understanding religion as magic to its interpretation as myth; the conception of the camouflage of sacred; the notions of androgyny and restoration; and also young Eliade’s theories of death.

The paper also discusses Idel’s evaluation of Eliade’s programatic misunderstanding of Judaism and Kabbalah, and also of Eliade’s moral and professional abdication regarding the political and religious aspect of the Iron Guard, a Romanian nationalist extremist and anti-Semitic group he was affiliated with in 1930s.

description: We utilized a chemically grown silicon dioxide (SiO2) layer produced by nitric acid oxidation of silicon (NAOS) formed by various passivation techniques to improve the passivation quality of pyramidal textured surfaces of bifacial passivated emitter and rear cells (PERC) for advanced light management. Two types of symmetrical sample structure, phosphorus-diffused samples and non-diffused samples having the same front and rear sides of a cell, respectively, were fabricated. In this study, we focused on the influence of different oxidation temperatures of NAOS to form the SiO2 layer and thermal annealing in situ hydrogenation conditions on the interfacial properties of the samples. As a result, the non-diffused samples that included the NAOS-SiO2 layer were negatively modified, showing reductions in open-circuit voltage (iVoc) with oxidation temperature and thermal annealing ambient. When the NAOSSiO2 layer was formed at boiling temperature, the iVoc values of non-diffused samples showed further losses compared with samples obtained at room temperature, attributed to the lower density of dangling bonds, exhibiting an increase in interface trap density (Dit). In contrast, the phosphorus-diffused samples passivated by NAOS-SiO2 formed at boiling temperature showed a different behavior, having positive effects on iVoc regardless of the thermal annealing ambient. The disparity of passivation behavior (negative or positive effect) may be related to NAOS-SiO2 thickness as well as different doping surface concentrations. The oxidation temperature for SiO2 formation also plays a key role in obtaining a high level of surface passivation through the hydrogenation process, where the recombination processes in the textured surface of silicon involve many other parameters.

description: A previous work establishing a connection between a quark model, with relativistic kinematics and a $Y$-confinement plus one gluon exchange, and the $1/N_c$ expansion mass formula is extended to strange baryons. Both methods predict values for the SU(3)-breaking mass terms which are in good agreement with each other. Strange and nonstrange baryons are shown to exhibit Regge trajectories with an equal slope, but with an intercept depending on the strangeness. Both approaches agree on the value of the slope and of the intercept and on the existence of a single good quantum number labeling the baryons within a given Regge trajectory.

description: Based on first-principles calculations, we study the origin of the large thermopower in Ni-doped LaRhO3 and Mg-doped CuRhO2. We calculate the band structure and construct the maximally localized Wannier functions from which a tight binding Hamiltonian is obtained. The Seebeck coefficient is calculated within the Boltzmann's equation approach using this effective Hamiltonian. For LaRhO3, we find that the Seebeck coefficient remains nearly constant within a large hole concentration range, which is consistent with the experimental observation. For CuRhO2, the overall temperature dependence of the calculated Seebeck coefficient is in excellent agreement with the experiment. The origin of the large thermopower is discussed.

Sustainability and Recycling

description: 36th European Photovoltaic Solar Energy Conference and Exhibition; 1241-1246
description: Silver is one of the most valuable and scarce materials used in photovoltaic manufacturing hence attracts much attention to be recycled when these solar cells enter end-of-life. Here, we demonstrate a novel method for rapid recycling of front silver metallisation from decommissioned silicon photovoltaic devices. The externally applied electric field accelerates the dissolution of silver into the recycling bath and drives the simultaneous deposition of silver on a recycling object. This single-step recycling method can recover more than 75% silver from these retired devices within a short time. Recycled silver has a high purity (> 99%) to be reused in the industry. Furthermore, life cycle assessment results show that this accelerated process has low environmental impacts, because it uses low quantities of chemical and electricity. These impacts can be further decreased by recirculating the chemical and improving the electric current efficiency. The low-impact silver recycling process presented in this paper is very simple and timeefficient thereby has a great potential for commercial PV recycling applications.

description: We study the high density region of QCD within an effective model obtained in the frame of the hopping parameter expansion and choosing Polyakov type of loops as the main dynamical variables representing the fermionic matter. To get a first idea of the phase structure, the model is analyzed in strong coupling expansion and using a mean field approximation. In numerical simulations, the model still shows the so-called sign problem, a difficulty peculiar to non-zero chemical potential, but it permits the development of algorithms which ensure a good overlap of the Monte Carlo ensemble with the true one. We review the main features of the model and present calculations concerning the dependence of various observables on the chemical potential and on the temperature, in particular of the charge density and the diquark susceptibility, which may be used to characterize the various phases expected at high baryonic density. We obtain in this way information about the phase structure of the model and the corresponding phase transitions and cross over regions, which can be considered as hints for the behaviour of non-zero density QCD.

description: In the PV industry, there is still a sustained cost pressure in the entire production chain of PV modules. Incidentally, the demand for ever higher efficiencies is another challenge to the material quality in substrate production on the one hand and cell technology on the other hand. For the production of monocrystalline silicon ingots by the Cz process, this means the demand for an extremely productive technology of crystal pulling systems as well as for cost-saving processes. Based on these considerations, a mobile recharge system was developed that allows for the multipulling technique that is the sequential pulling of several crystals from a single crucible. This mobile feeding system offers the unique possibility to serve several Cz-pullers time delayed, which means less investment. In addition, an active crystal cooling device has been developed, which can be retrofitted and allows a significant increase in the pull speed. The combination of active crystal cooling with multipulling enables a strong reduction in production costs of silicon crystals. Another way to reduce costs is to use larger melt weights (primary loadings) to minimize unproductive crystal growing process times (neck, shoulder, cone phase). When increasing the primary loadings, however, the process stability must be taken into account. This raises the question to what extent large melt volumes with the resulting turbulent convection phenomena can be controlled without the use of magnetic fields to dampen the convection phenomena.

description: Partial shading affects the performance and reliability of thin-film and crystalline-silicon (c-Si) photovoltaic (PV) modules. In this paper, the thin-film and c-Si modules are experimentally benchmarked by introducing various partial shading patterns over the modules. More specifically, experiments are performed using SPISUN 5600 SLP-based test-rig. The benchmarking reveals that thin-film and c-Si technologies behave differently under the same shading patterns. Furthermore, thermographic images are also presented to explore the effect of partial shading on both modules.

description: The ARCH process (R. F. Engle, 1982) constitutes a paradigmatic generator of stochastic time series with time-dependent variance like it appears on a wide broad of systems besides economics in which ARCH was born. Although the ARCH process captures the so-called "volatility clustering" and the asymptotic power-law probability density distribution of the random variable, it is not capable to reproduce further statistical properties of many of these time series such as: the strong persistence of the instantaneous variance characterised by large values of the Hurst exponent (H > 0.8), and asymptotic power-law decay of the absolute values self-correlation function. By means of considering an effective return obtained from a correlation of past returns that has a q-exponential form we are able to fix the limitations of the original model. Moreover, this improvement can be obtained through the correct choice of a sole additional parameter, $q_{m}$. The assessment of its validity and usefulness is made by mimicking daily fluctuations of SP500 financial index.

Inverters and Balance of System Components

description: 36th European Photovoltaic Solar Energy Conference and Exhibition; 1212-1216
description: This work is discussing different electric setups for testing active components connected to the lowvoltage grid. Active components such as grid-connected PV inverters can be tested by means of hardware-only test setups implemented in physical hardware implementation in the laboratory. Alternatively, components such as these can also be described as real-time capable models which may run on a real-time computing machine. With this concept, also the peripheral hardware of the PV inverter can be emulated. Only the control board is existing as a hardware component which is subsequently connected to the real-time simulator via I/O ports carrying input and output signals. With the help of this controller hardware-in-the-loop simulation methodology, the testing of the inverter device is facilitated and results are compared to the hardware-only test setup for the purpose of validation. This work includes the explanation of the different test setups and explains different use cases in which CHIL setups and hardware only setups may be used for the purpose of validated investigations.

description: UVFL is an emerging inspection method which is useful to check the defects in the installed PV modules. The cracks in the PV cells can be seen when the module is under UV exposure, and it is easier than EL for checking the health condition of the PV modules. However the florescence induced by the UV light is too weak that it can only be seen within a short distance. The inspectors need to walk through all PV panels in a PV plant to check the defects, which is time consuming and require huge human resource. Furthermore, the UV light is harmful to human eyes, so the inspection in short distance increases the risk of the inspectors. In this work we developed one set of devices to perform the UVFL inspection with a drone, and it greatly saves the inspection time and effort, and also keeps the inspectors in a safe distance from the UV light. With the inspection tool, a special UVFL mode was found in the field, and the root cause of the phenomenon was determined through the comparison of the module materials.

description: The condition of a solar PV panel can be evaluated by its measured electrical characteristics. The singlediode model parameters extracted from a measured current-voltage curve may indicate the possible presence of degradation. Aging of PV cells is a common source of degradation and manifests itself typically in increased series resistance values, causing a decline in the voltage characteristics of a PV panel. However, the current and voltage characteristics of a PV panel change considerably with changing environmental conditions, especially with changing irradiance and temperature. Accordingly, the single diode model parameter values change along variations in the surrounding environmental conditions, making the comparison of any two distinct current-voltage curves measured in outdoor conditions difficult. This gives a reason for converting the identified single diode model parameters of a measured curve from actual operating conditions to common reference conditions. In this light, we study the relation between the PV panel voltage and series resistance under different environmental conditions. We also investigate the feasibility of parameter reversion back to standard test conditions.

description: We write down M2-branes on the resolved $C_4/Z_4$ orbifold space. The resolved spatial geometry is such that it interpolates between $R^2\times CP_3$ near the branes and $C_4/Z_4$ asymptotically. The near horizon geometry of these branes is a deformation of $AdS_4\times S^7/Z_4$. An interesting aspect is that for $k=4$ Chern-Simons theory coupling becomes vanishing near the IR cutoff leading to spontaneous compactification to type IIA.

Optical colours of AGN in the Extended Chandra Deep Field South: Obscured black holes in early type galaxies

description: We investigate the optical colours of X-ray sources from the Extended Chandra Deep Field South (ECDFS) using photometry from the COMBO-17 survey, aiming to explore AGN - galaxy feedback models. The X-ray sources populate both the ``blue'' and the ``red sequence'' on the colour-magnitude diagram. However, sources in the ``red sequence'' appear systematically more obscured. HST imaging from the GEMS survey demonstrates that the nucleus does not affect significantly the observed colours, and therefore red sources are early-type systems. In the context of AGN feedback models, this means that there is still remaining material after the initial ``blowout''. We argue that this material could not be only left-over from the original merger, but a secondary cold gas supplier (such as minor interactions or self-gravitational instabilities) must also assist.

description: A class of thick branes in the background of sine-Gordon kinks with a scalar potential $V(ϕ)=p(1+\cos\frac{2ϕ}{q})$ was constructed by R. Koley and S. Kar [Classical Quantum Gravity \textbf{22}, 753 (2005)]. In this paper, in the background of the warped geometry, we investigate the issue of localization of spin half fermions on these branes in the presence of two types of scalar-fermion couplings: $η\barΨϕΨ$ and $η\barΨ\sinϕΨ$. By presenting the mass-independent potentials in the corresponding Schrödinger equations, we obtain the lowest Kaluza--Klein (KK) modes and a continuous gapless spectrum of KK states with $m^2>0$ for both types of couplings. For the Yukawa coupling $η\barΨϕΨ$, the effective potential of the right chiral fermions for positive $q$ and $η$ is always positive, hence only the effective potential of the left chiral fermions could trap the corresponding zero mode. This is a well-known conclusion which had been discussed extensively in the literature. However, for the coupling $η\barΨ\sinϕΨ$, the effective potential of the right chiral fermions for positive $q$ and $η$ is no longer always positive. Although the value of the potential at the location of the brane is still positive, it has a series of wells and barriers on each side, which ensures that the right chiral fermion zero mode could be trapped. Thus we may draw the remarkable conclusion: for positive $η$ and $q$, the potentials of both the left and right chiral fermions could trap the corresponding zero modes under certain restrictions.

description: This paper describes the development of and first experiences with 'Design Your Life': a novel method aimed at user-initiated design of technologies supporting young autistic adults in independent living. A conceptual, phenomenological background resulting in four core principles is described. Taking a practice-oriented Research-through-Design approach, three co-design case studies were conducted, in which promising methods from the co-design literature with the lived experiences and practical contexts of autistic young adults and their caregivers is contrasted. This explorative inquiry provided some first insights into several design directions of the Design Your Life-process. In a series of new case studies that shall follow, the Design Your Life-method will be iteratively developed, refined and ultimately validated in practice.

description: The study of complex oxides and oxide heterostructures have dominated the field of experimental and theoretical condensed matter research for the better part of the last few decades. Powerful experimental techniques like molecular beam epitaxy and pulsed laser deposition have made fabrication of oxide heterostructures with atomically sharp interfaces possible, while more and more sophisticated handling of exchange and correlations within first principles methods including density functional theory (DFT) supplemented with Hubbard U corrections and hybrid functionals, and beyond DFT techniques like dynamical mean field theory (DMFT) have made understanding of such correlated oxides and oxide interfaces easier. The emergence of the high mobility two dimensional electron gas with fascinating properties like giant photoconductance, large negative magnetoresistance, superconductivity, ferromagnetism, and the mysterious coexistence of the latter two have indeed caught the attention of condensed matter community at large. Similarly strain tuning of oxides have generated considerable interest particularly after the recent discovery of piezoelectric methods of strain generation. Theoretical understanding and prediction of the possible exotic phases emerging in such complex oxides both under strain and in heterostructures will eventually lead to better design of device applications in this new emerging field of oxide electronics, along with possible discovery of exotic physics in condensed matter systems which may be of wider significance! In this review we briefly look at theoretical studies of novel phenomena in oxides under strain and oxide heterostructures, and try to understand the role of exchange and particularly correlation in giving rise to such exotic electronic states.

description: This paper compares the profitability of swine enterprises according to scale of operation and production system in two major hog-producing towns in Bulacan, Philippines. Results are based on a survey of 145 hog raisers — 71 from the City of San Jose del Monte (CSJDM) and 74 from Santa Maria. The CSJDM enterprises have higher net income per head than the Santa Maria enterprises but the latter have slightly higher profit-to-sales ratio. By scale of operation, medium commercial enterprises are the most profitable in both areas and found to have sold their produce at the highest price. Across production systems, the farrow-to-breeder-finisher in CSJDM registers the highest proportion of profit to sales. This system sells multiple products and its breeder stocks are sold at higher prices. The boar-for-hire production system has the lowest profit-to-sales ratio, which is attributed to the increasing utilization of artificial insemination in CSJDM. In the case of the Santa Maria enterprises, the farrow-to-finish production system registers the highest income on a per head basis; the lowest for the growing-finishing production system. By scale of operation, the internal factors which determine profitability are the number of hogs raised and the utilization of high-quality feeds. By production system, the critical internal factors are the types and prices of animals sold, feeds, and capital for weaners. A favorable enabling environment, including improved incentive system and accessible credit, can help promote commercial and integrated swine enterprises in the study area.
