Nundalia

description: Genus Nundalia n. gen.
Type species: Nundalia secreta n. sp.
Description. Shell small, conical, whorls convex, with growth lines only; peristome slightly to moderately thickened, non-umbilicate but umbilical chink present. Operculum thin, yellowish, subpyriform, paucispiral with last whorl large, nucleus acentric; inner surface with 2 or 3 reduced pegs near nucleus. Radula with central teeth having numerous cusps, median cusp narrow, sharp, about same length as adjacent cusps; lateral margins wide; innermost basal cusps rather narrow, sharp; basal tongue narrow, U-shaped. Male with prostate gland ovoid, with more than half in pallial roof. Pallial vas deferens simple to slightly undulating. Penis simple, of even thickness until distal end where it tapers to short papilla; glands and processes absent. Female with coiled oviduct with short, anteriorly-pointing arch. Bursa copulatrix short, behind albumen gland. Oviduct narrow, ventral channel simple, with slightly expanded vestibule and terminal slit-like opening. Albumen gland with about anterior third in pallial roof; without associated cowl or gutter.
Distribution. The type species is from swampy head waters of streams on the Great Dividing Range in the vicinity of Nundle, inland from Port Macquarie, lower North Coast, New South Wales.
Contained species. None previously described, one new species described below.
Etymology. Named for the town of Nundle, New South Wales. Gender feminine.
Remarks. This genus differs from other members of the Jardinella group in having an operculum with reduced pegs. These are much more developed than the rudimentary protuberances seen in some other members of the group. The radula is distinctive in having numerous sharp cusps on the central and lateral teeth. The bursa is short and subtriangular, with the bursal duct opening mid ventrally, a feature shared with Conondalia but not seen in other members of the Jardinella group.
No other species in this group are known from the general area in which it occurs, although it has not been well surveyed and other species may well be located in the future in streams along the Great Dividing Range of northern New South Wales.

description: Several recent IFPRI studies have measured the effects of public spending on growth and poverty reduction in selected Asian countries using pooled time-series and cross-region data. However, many African countries lack such data. Using Tanzania as a test case, this study demonstrates how household survey data can be used to assess the impacts of public investments on growth and poverty. A two step procedure is used. First, household survey data are used to link household welfare measures to human capital and household access to infrastructure and technology, while controlling for other community and household characteristics. The second step links household human capital and access to infrastructure and technology to past public investments in these factors. As in the Asian studies, the growth effects (measured as per capita income) of investments in agricultural research, roads, and education are found to be large. But unlike Asia, no clear distinction emerges between the measured impacts for high and low potential areas. In many high potential areas, returns to investments are still high and there is no sign of any diminishing marginal returns. This suggests that there has been insufficient public investment in all kinds of regions. Nevertheless, the results show that there is opportunity to improve on the growth and poverty impacts of total public investment through better regional targeting of specific types of investment. For example, additional investments in rural education have attractive growth and poverty impacts in all regions, whereas additional investments in roads and agricultural research are better spent in the central and southern regions of the country.

description: We propose a sophisticated framework for high-energy hadronic collisions, wherein different QCD physics processes are interleaved in a common sequence of falling transverse-momentum values. Thereby phase-space competition is introduced between multiple parton-parton interactions and initial-state radiation. As a first step we develop new transverse-momentum-ordered showers for initial- and final-state radiation, which should be of use also beyond the scope of the current article. These showers are then applied in the context of multiple interactions, and a few tests of the new model are presented. The article concludes with an outlook on further aspects, such as the possibility of a shower branching giving partons participating in two different interactions.

description: The effect of a strong magnetic field on the dominant neutrino emissivity in strange stars is investigated. In ultra strong magnetic field, there exists an enhanced neutrino emission because the charged particles are confined to the lowest Landau level. The results show that the neutrino emissivity is proportional to $T^5$ instead of conventional $T^6$, which implies more rapid cooling behavior in magnetars than usual stars

description: The opportunity cost of water in the irrigation industry is a contentious issue at present because of the commitment made by the State and Commonwealth governments to get water out of the irrigation industry for environmental flows. The estimated value of the opportunity cost will affect farmers' claims for compensation. Variation in the opportunity cost over space and the functioning of the spatial market will determine whether the efficiency costs of a simple across the board reduction in rights can be mitigated by trade or whether strategic buy back of water is required. The extent of variation in the opportunity cost of water according to seasonal conditions will affect the cost of flow policies that impact on the reliability of rights. To date, most economic advice on this opportunity cost of water has centred on gross margin analysis of the main irrigation uses of water and the compensation of these industries across space compared to the quantity of rights held. However, there has been a large volume of trade on temporary water markets in recent years and there is potential for using this data to better understand some of the characteristics of water demand and the market for water. This paper presents a preliminary analysis of market data from the last 5 years of trade on the Northern Victorian water exchange. The nature of bidding behaviours and spatial and temporal variations in water prices is illustrated, and the impact of water allocations and seasonal conditions on water prices is estimated.

The gas temperature in the surface layers of protoplanetary disks

description: Models for the structure of protoplanetary disks have so far been based on the assumption that the gas and the dust temperature are equal. The gas temperature, an essential ingredient in the equations of hydrostatic equilibrium of the disk, is then determined from a continuum radiative transfer calculation, in which the continuum opacity is provided by the dust. It has been long debated whether this assumption still holds in the surface layers of the disk, where the dust infrared emission features are produced. In this paper we compute the temperature of the gas in the surface layers of the disk in a self-consistent manner. The gas temperature is determined from a heating-cooling balance equation in which processes such as photoelectric heating, dissociative heating, dust-gas thermal heat exchange and line cooling are included. The abundances of the dominant cooling species such as CO, C, C+ and O are determined from a chemical network based on the atomic species H, He, C, O, S, Mg, Si, Fe (Kamp & Bertoldi 2000). The underlying disk models to our calculations are the models of Dullemond, van Zadelhoff & Natta (2002). We find that in general the dust and gas temperature are equal to withing 10% for A_V >~ 0.1, which is above the location of the `super-heated surface layer' in which the dust emission features are produced (e.g. Chiang & Goldreich 1997). High above the disk surface the gas temperature exceeds the dust temperature and can can become -- in the presence of polycyclic aromatic hydrocarbons -- as high as 600 K at a radius of 100 AU. This is a region where CO has fully dissociated, but a significant fraction of hydrogen is still in molecular form. The densities are still high enough for non-negligible H_2 emission to be produced.....(see paper for full abstract)

description: It is notoriously difficult to assess the economic value of research aimed at improving research capacity, particularly in enhancing human capital. In this paper, a framework is developed and an analysis is undertaken of the value of training for scientists in wheat rust resistance in India. The value of the training is assessed through marginal analysis of the improvement in the level of disease resistence flowing from the increased capacity. On that basis, the value of programs to build human capacity through training or further education can be estimated. While such estimates need to be highly qualified, they provide a basis for quantifying the value of R&D capacity building.

Estimating wood physical properties by using microwave measurements
Creators: name: Orhan, Fatos Bahar
Publisher: name: University of British Columbia
Year: 2009

description: Wood is a natural material with a wide range of physical properties. For effective use of the material resource, it is important to be able to make reliable non-destructive measurements of material properties. Of particular interest here are grain angle, moisture content and density of wood. These are important for process control and for wood strength estimation. Microwaves provide an effective method for measuring wood properties. The measurements are non-contact, high speed and safe. Their data content is also very rich, with a total of eight independent measurements at each point. Thus, there is good opportunity for reliable material property evaluation and for data consistency checking. The microwave system described here measures the attenuation and phase change of a microwave beam as it propagates through wood specimens. It makes these measurements for both parallel and perpendicular polarizations. In this study, microwave measurements are made on 76 hemlock and 150 Douglas fir pieces. The collected data are used to estimate the wood grain angle, moisture content and density. For estimations, linear models whose coefficients are calculated by applying least-squares method are constructed. Also, since temperature has a significant influence on electrical properties, the temperature is taken into account as a variable in the formulations. A significant species dependence was observed in the results, with different moisture and wood density sensitivities for hemlock and Douglas fir. In general, the results from hemlock were superior to those from Douglas fir. For hemlock and Douglas fir respectively, 3 3 the standard error of estimation (SEE) of wet density was 4kg/m3 and l0kg/m3 (moisture density range = 40-120 kg/m3 ). For dry wood density, the SEE was 40 and 65 kg/m3 (dry wood density range = 300-650 kg/m3). For moisture content, the SEE was 1.0% and 2.0% (moisture content range = 6-30%). For grain angles, the SEE was 0.9 and 2.5 degrees (grain angle range = 0-180°). All these results indicate that the microwave method has substantial practical potential as a method for estimating wood moisture density, moisture content and grain angle.

description: We study meron quasiparticle excitations in the ν= 1 quantum Hall bilayer. Considering the well known single meron state, we introduce its effective form, valid in the longdistance limit. That enables us to propose two (and more) meron states in the same limit. Further, establishing a plasma analogy of the (111) ground state, we find the impurities that play the role of merons and derive meron charge distributions. Using the introduced meron constructions in generalized (mixed) ground states and corresponding plasmas for arbitrary distance between the layers, we calculate the interaction between the construction implied impurities. We also find a correspondence between the impurity interactions and meron interactions. This suggests a possible explanation of the deconfinement of the merons recently observed in the experiments.

description: This article investigates the impact of agronomic, environmental, and price information on the management decision of nitrogen fertilizer. Because excessive nitrogen originating from agricultural production activities can cause environmental degradation, understanding how information influences the nutrient application decision on the field is important for developing strategies for nitrogen load mitigation. I investigate the value farmers place on information about N management they receive from several sources. In particular, I evaluate how farmers use information from soil N-tests to make decisions about the rate of N to apply to the field. My results show that soil N-testing can be an effective management practices for reducing excess N applications. I find farmers who use a soil test reduce their use of commercial N by up to 14 lbs/ac relative to non-testers. I also find new evidence that rising fertilizer prices encourage farmers to manage N more carefully. I estimate a price elasticity of demand of between -0.6 and -1.29. I also show prices play a role in other forms of N management behavior, including application method and timing.
Development and testing of an aerodynamic marine propeller test facility : an investigation into making boats fly
Creators: name: Davis, Karl Richard
Publisher: name: University of British Columbia
Year: 2009

description: Current techniques for performance testing marine propellers involve the use of extremely expensive facilities such as towing tanks or cavitation tunnels. These methods are also limited as to the maximum propeller size they can test. If it were possible to perform such testing in a more commonly available wind tunnel, marine propeller testing and research could be carried out more widely and upon larger propellers. A device for testing marine propeller performance in a wind tunnel has been designed, built and commissioned. The device features a marine propeller that is 24 inches in diameter that can be spun at up to 3000rpm. Instrumentation for measuring the propeller's thrust, torque, rotational speed and the wind tunnel free stream velocity are integral features of the device. Dimensional analysis was applied to ensure the applicability and validity of the results determined in air to the hydrodynamic case. A series of tests were performed with the equipment to investigate the repeatability of the results, the effect of varying Reynolds number, and to evaluate the device as a comparative tool. The repeatability was found to vary with test conditions. For the preferred test speed of 1500rpm, a repeatability of 1.3% was achieved at peak efficiency. The Reynolds number investigation showed that as the Reynolds number increased, the Reynolds number dependence of the results was reduced. The goal, however, of finding a test speed which exhibited Reynolds number independence was not achieved. The comparative performance test involved testing two identically specified propellers. Subtle differences in the performance characteristics of the two propellers were observed.

description: A carbon tax would penalize carbon intensive fuels like gasoline and shift fuel consumption to less carbon intensive alternatives like biofuels. Since biofuel production competes for land with agriculture, a carbon tax could raise land rents, divert land towards fuel production, and raise agricultural prices. This paper analyzes the welfare effect of a carbon tax on fuel with gasoline and biofuel as available fuel choices, in the presence of a labor tax and biofuel subsidy. The second-best optimal carbon tax is also quantified. Findings show that when biofuels is part of the fuel mix, the carbon tax has a commodity price effect which arises from tax-induced changes in land rent. The commodity price effect could exacerbate or attenuate the tax interaction effect caused by higher fuel prices, depending on the elasticity of substitution between gasoline and biofuel, the price elasticity of miles demand, and the relative emissions intensity of gasoline and biofuel. Numerical results show that the commodity price effect affects the value of the second-best optimal carbon tax, and that the effect is greater if the elasticity of substitution between gasoline and biofuel is high, miles is more price inelastic, and the GHG intensity of biofuel is lower compared to gasoline. In addition the existence of a fixed biofuel subsidy leads to a greater divergence between the value of the second-best optimal carbon tax with or without biofuels. A carbon tax policy decreases GHG emissions and increases welfare, in contrast to a biofuel subsidy, which also decreases GHG emissions but at a net welfare loss.

description: We investigate the failure characteristics of complex networks within the framework of the fiber bundle model subject to the local load sharing rule in which the load of the broken fiber is transferred only to its neighbor fibers. Although the load sharing is strictly local, it is found that the critical behavior belongs to the universality class of the global load sharing where the load is transferred equally to all fibers in the system. From the numerical simulations and the analytical approach applied to the microscopic behavior, it is revealed that the emergence of a single dominant hub cluster of broken fibers causes the global load sharing effect in the failure process.

description: Corn ethanol produced in the US and sugarcane ethanol produced in Brazil are the world’s leading sources of biofuel. Current US biofuel policies create both incentives and constraints for the import of ethanol from Brazil, and together with the competitiveness and greenhouse gas intensity of sugarcane ethanol compared to corn ethanol will determine the extent of these imports. This study analyzes the supply-side determinants of this competitiveness and compares the greenhouse gas intensity of corn ethanol and sugarcane ethanol delivered to US ports. We find that while the cost of sugarcane ethanol production in Brazil is lower than that of corn ethanol in the US, the inclusion of transportation costs for the former and co-product credits for the latter changes their relative competitiveness. We also find that the relative cost of ethanol in the US and Brazil is highly sensitive to the prevailing exchange rate and prices of feedstocks. At an exchange rate of US$1 = R$2.15 the cost of corn ethanol is 15% lower than the delivered cost of sugarcane ethanol at a US port. Sugarcane ethanol has lower GHG emissions than corn ethanol but a price of over $113 per ton of CO2 is needed to affect competitiveness.

The different cases are studied and the corresponding potentials are reconstructed. The exact solutions are obtained, which show a similar behaviour to the single scalar field model. For one of the cases analyzed in the paper, the so-called adiabatic field also constant rolls while entropy perturbations become null, while the second case may lead to non-adiabatic perturbations. Both cases can fit well the Planck data by assuming the appropriate values for the free parameters of the models.

We find that this star is hydrogen-rich with Teff ~ 10 500 K, log g ~ 5.9, and, following evolutionary models, has a mass of ~ 0.17 solar masses. Independent analysis of radial velocity and TESS photometric time series reveals an orbital period of ~ 9.5 h. Its high velocity amplitude (K ~ 144 km/s) produces a measurable Doppler beaming effect in the TESS light curve with an amplitude of 1 mmag. The unseen companion is most likely a faint white dwarf. J0500-0930 belongs to a class of post-common envelope systems that will most likely merge through unstable mass transfer and in specific circumstances lead to Type Ia supernova explosions.

description: The phenomenon of quartet condensation in the ground state of an isovector pairing Hamiltonian for an even-even $N=Z$ system is investigated. For this purpose we follow the evolution of the ground state from an unperturbed regime up to a strongly interacting one in a formalism of collective pairs. These pairs are those resulting from the diagonalization of the pairing Hamiltonian in a space of two particles coupled to isospin $T=1$. The ground state is found to rapidly evolve from a product of distinct $T=0$ quartets, each one formed by two of the above pairs, to a condensate of identical quartets built only with the pair corresponding to the lowest energy. This finding establishes a link between the complicated structure of the exact ground state and the simple approximation scheme of the Quartet Condensation Model. The mechanism at the basis of this quartet condensation turns out to be the same which is responsible for the development of a pair condensate in the ground state of a like-particle pairing Hamiltonian.

description: This paper presents an overview of current and upcoming trade related regulations of genetically modified (GM) food, and analyzes their effects on trade, consumers, and producers. Using a three-country analytical model of welfare and political interests, the study assesses the economic effects and motivation behind the adoption of import approval regulations, information requirements for GM commodity shipments, and GM food marketing policies. The results of the analysis show that in a non-GM producing country, trade-related regulations will benefit producers, but not necessarily consumers. Thus, while consumers may play a role in supporting import approval regulations, producers’ support is likely to be instrumental to the adoption of all other types of regulations. Outside pressure groups will play the role of swing voters in cases where consumers and producers do not agree, such as on mandatory labeling of GM food, information requirements, or potentially to support GM-free private standards.

description: The relativistic treatment of spin is a fundamental subject which has an old history. In various physical contexts it is necessary to separate the relativistic total angular momentum into an orbital and spin contribution. However, such decomposition is affected by ambiguities since one can always redefine the orbital and spin part through the so-called pseudo-gauge transformations. We analyze this problem in detail by discussing the most common choices of energy-momentum and spin tensors with an emphasis on their physical implications, and study the spin vector which is a pseudo-gauge invariant operator. We review the angular momentum decomposition as a crucial ingredient for the formulation of relativistic spin hydrodynamics and quantum kinetic theory with a focus on relativistic nuclear collisions, where spin physics has recently attracted significant attention. Furthermore, we point out the connection between pseudo-gauge transformations and the different definitions of the relativistic center of mass. Finally, we consider the Einstein-Cartan theory, an extension of conventional general relativity, which allows for a natural definition of the spin tensor.

Self-dual Einstein spaces and the general heavenly equation. Eigenfunctions as coordinates

description: Eigenfunctions are shown to constitute privileged coordinates of self-dual Einstein spaces with the underlying governing equation being revealed as the general heavenly equation. The formalism developed here may be used to link algorithmically a variety of known heavenly equations. In particular, the classical connection between Plebanski's first and second heavenly equations is retrieved and interpreted in terms of eigenfunctions. In addition, connections with travelling wave reductions of the recently introduced TED equation which constitutes a 4+4-dimensional integrable generalisation of the general heavenly equation are found. These are obtained by means of (partial) Legendre transformations. As a particular application, we prove that a large class of self-dual Einstein spaces governed by a compatible system of dispersionless Hirota equations is genuinely four-dimensional in that the (generic) metrics do not admit any (proper or non-proper) conformal Killing vectors. This generalises the known link between a particular class of self-dual Einstein spaces and the dispersionless Hirota equation encoding three-dimensional Einstein-Weyl geometries.
Nature and Origin of Unusual Properties in Chemically Exfoliated 2D MoS_2

description: MoS_2 in its two-dimensional (2D) form is known to exhibit many fundamentally interesting and technologically important properties. One of the most popular routes to form extensive amount of such 2D samples is the chemical exfoliation route. However, the nature and origin of the specific polymorph of MoS_2 primarily responsible for such spectacular properties has remained controversial with claims of both T and T' phases as well as metallic and semiconducting natures. We show that a comprehensive scrutiny of the available literature data of Raman spectra from such samples allow little scope for such ambiguities, providing overwhelming evidence for the formation of the T' phase as the dominant metastable state in all such samples. We also explain that this small band-gap T' phase may attain substantial conductivity due to thermal and chemical doping of charge-carriers, explaining the contradictory claims of metallic and semiconducting nature of such samples, thereby attaining a consistent view of all reports available so far.

description: Following a short review of the major trends that characterize the globalization process at the economic, political-ideological and socio-cultural levels, this article takes a look at the rationality of agricultural cooperatives and reflects on the effects of globalization. Understanding globalization as a dialectical process, my reflection will draw on the effects of globalization on cooperatives, in particular agricultural ones. I am referring to the threats, challenges and opportunities brought about by globalization. This means evaluating the threats and opportunities that result essentially from increased competition, trade liberalization and changes in the role of the Nation-sates. The article ends with some conclusive remarks.

description: This paper discusses how the current institutional framework and market competition affect the strategies of Latin American agricultural cooperative's businesses. Faced with the trend of organizational isomorphism, it is important to deepen our understanding of the values and principles of cooperatives, incorporating them into competitive strategies, relying on cooperation, trust and loyalty as coordinating forces of economic activities and as sources of competitive difference in the agricultural system.

description: Agricultural cooperatives in Brazil, as in other countries, develop through vertical integration in order to promote industrialization of the agricultural product and to aggregate the value of agricultural commodities. The vertical integration strategy was a predominant business planning adopted by Brazilian agricultural cooperatives in the 1980s. It was responsible for greater assets in cooperatives, larger agro industrial plants, and higher debt structure. Nowadays, it is possible to observe new agro industrial cooperative organizations in Brazil called "Virtual Cooperatives." These virtual organizations do not possess significant assets or industrial plants, but represent a network that has a particular business strategy in the markets. In order to discuss virtual cooperatives, this paper describes the agricultural cooperatives in Brazil, the globalization process, and the institutional environment that has given rise to virtual cooperatives. The paper also describes the nature of a virtual cooperative, and the advantages and disadvantages when these organizations are compared to traditional agro industrial cooperatives. Two different virtual cooperatives cases studies are presented.
Properties of Molecular Gas in Massive Low Surface Brightness Galaxies, Including New 12CO Observations of Three Malin 1 `Cousins'

description: To date, the only low surface brightness (LSB) galaxies which have been detected in CO are the Massive LSB (MLSB) galaxies. In 2003, O'Neil, Schinnerer, & Hofner hypothesized that is the prominent bulge component in MLSB galaxies, not present in less massive low surface brightness galaxies, which gives rise to the detectable quantities of CO gas. To test this hypothesis, we have used the IRAM 30m telescope to obtain three new, deep CO J(1-0) and J(2-1) observations of MLSB galaxies. Two of the three galaxies observed were detected in CO - one in the J(1-0) line and the other in both the J(1-0) and J(2-1) lines, bringing the total number of MLSB galaxies with CO detections to 5, out of a total of 9 MLSB galaxies observed at CO to date. The third object had no detection to 2 mK at CO J(1-0). Comparing all MLSB galaxy CO results with surveys of high surface brightness galaxies, we find the MLSB galaxies' MH2 and MH2/MHI values fall within the ranges typically found for high surface brightness objects, albeit at the low end of the distribution, with the two MLSB galaxies detected at CO in this survey having the highest MH2/MHI values yet measured for any LSB system, by factors of 2-3.

description: We have discovered a 300kpc-wide giant Lya nebula centered on the massive galaxy group RO-1001 at z=2.91 in the COSMOS field. Keck Cosmic Web Imager observations reveal three cold gas filaments converging into the center of the potential well of its ~4x10^13Msun dark matter halo, hosting 1200Msun/yr of star formation as probed by ALMA and NOEMA observations. The nebula morphological and kinematics properties and the prevalence of blueshifted components in the Lya spectra are consistent with a scenario of gas accretion. The upper limits on AGN activity and overall energetics favor gravity as the primary Lya powering source and infall as the main source of gas flows to the system. Although interpretational difficulties remain, with outflows and likely also photoionization with ensuing recombination still playing a role, this finding provides arguably an ideal environment to quantitatively test models of cold gas accretion and galaxy feeding inside an actively star-forming massive halo at high redshift.

description: We briefly review the status of the application of carbon nanotubes (CNTs) for future interconnects and present results concerning possible integration schemes. Growth of single nanotubes at lithographically defined locations (vias) has been achieved which is a prerequisite for the use of CNTs as future interconnects. For the 20 nm node, a current density of 5 10^8 A/cm^2 and a resistance of 7.8 kOhm could be achieved for a single multi-walled CNT vertical interconnect.
