description: Born in 1987, the National Pig Producers Association (N.P.P.A.) today is a registered cooperative. This paper gives an idea of the evolution of the growth of this association through four main activities which are: feed sales, production, technical advice, and branch meetings. These activities are exclusively oriented towards production for the local market. This paper also explains how the N.P.P.A. could develop with the help of the Training, Research, Extension and Development Unit of the Ministry of Agriculture (TREDU). TREDU's involvement has been so heavy that it may have to learn now how to free itself from that situation. Pig production can be profitable in Dominica provided the pig producers follow a set of technical recommendations. But this production remains risky if done otherwise in the Dominican conditions. ----- La Dominique a principalement ba:ié son développement sur la production bananière qui represente en moyene 70ï. des recettes d'exportations chaque année. Nous savons aujourd'hui que "les trois soeurs" (Del Monte, United Brandt, Castle & Cook) sont capables de produire des bananes de qualité~ un coOt tierce des bananes de la Caraibe. Elles possèdent donc un moyen de pression colossal puisq' elles peuvent facilement diminuer leurs prix. Il est donc plus que probable qu'une diminution du prix de la banane voit le jour dans les années qui viennent. La diversification agricole représente alors un enjeu considerable puisqu' il s'agit de la sécurité du producteur. Cet article prés en tE, d'abord comment s'est opéré la croissance et l'organizatlon du groupe de producteur de porc en coopérative nationale avec pour objectif de couv·rir le marche local en viande porc. Puis cet article s'attache à analyser les problèmes majeurs d'ordre sociaux et economiques recontrés.

description: Genus Megacanthopora Moore, 1929
 Neorhombopora Shishova, 1964: 55.
 TYPE SPECIES. — Megacanthopora fallacis Moore, 1929 by monotypy. Graham Formation (Pennsylvanian); Texas, USA.
DIAGNOSIS. — Branched colonies with wide exozone (one-third to two-third of the branch radius). Autozooecia with oval apertures and irregularly thickened walls in the exozone, diverging at angles of 45° from the axis, intersecting the colony surface at angles of 80- 90°. Longitudinal arrangement of autozooecia irregular. Diaphragms complete, rare, occurring only in the exozone. Metazooecia rare to common. Acanthostyles uncommon. Aktinotostyles abundant, generally closely spaced, arising in the exozone. Autozooecial walls laminated, containing mural spines.
OCCURRENCE. —Lower Carboniferous – Upper Permian; worldwide.
COMPARISON
 Megacanthopora Moore, 1929 differs from Rhombopora Meek, 1872 in having abundant metazooecia.
REMARKS
 Astrova (1978), Dunaeva (1973), and Gorjunova (1985, 1996) assigned this genus to the Stenoporidae (Trepostomida). Blake (1983: 579-580) placed it in the Rhomboporidae (Rhabdomesina, Cryptostomata), and put the genus Neorhombopora Shishova, 1964 to the genus Megacanthopora Moore, 1929, because the type species Rhombopora crassa Ulrich, 1884 possesses acanthostyles.

description: Symmetric edge polytopes $\mathcal{A}_G$ of type A are lattice polytopes arising from the root system $A_n$ and finite simple graphs $G$. There is a connection between $\mathcal{A}_G$ and the Kuramoto synchronization model in physics. In particular, the normalized volume of $\mathcal {A}_G$ plays a central role. In the present paper, we focus on a particular class of graphs. In fact, for any cactus graph $G$, we give a formula for the $h^*$-polynomial of $\mathcal{A}_{\widehat{G}}$ by using matching generating polynomials, where $\widehat{G}$ is the suspension of $G$. This gives also a formula for the normalized volume of $\mathcal{A}_{\widehat{G}}$. Moreover, via the chemical graph theory, we show that for any cactus graph $G$, the $h^*$-polynomial of $\mathcal{A}_{\widehat{G}}$ is real-rooted. Finally, we extend the discussion to symmetric edge polytopes of type $B$, which are lattice polytopes arising from the root system $B_n$ and finite simple graphs.

description: Strongly-correlated two-dimensional electrons in coupled semiconductor bilayers display remarkable broken symmetry many-body states under accessible and controllable experimental conditions. In the cases of continuous quantum phase transitions soft collective modes drive the transformations that link distinct ground states of the electron double layers. In this paper we consider results showing that resonant inelastic light scattering methods detect soft collective modes of the double layers and probe their evolution with temperature and magnetic field. The light scattering experiments offer venues of research of fundamental interactions and continuous quantum phase transitions in low-dimensional electron liquids.

description: Given a system of equations in a "random" finitely generated subgroup of the braid group, we show how to find a small ordered list of elements in the subgroup, which contains a solution to the equations with a significant probability. Moreover, with a significant probability, the solution will be the first in the list. This gives a probabilistic solution to: The conjugacy problem, the group membership problem, the shortest representation of an element, and other combinatorial group-theoretic problems in random subgroups of the braid group. We use a memory-based extension of the standard length-based approach, which in principle can be applied to any group admitting an efficient, reasonably behaving length function.

description: The Resource Assessment Branch of the Department of Water Land and Biodiversity Conservation (DWLBC) is currently undertaking the ‘Northern Adelaide Plains Prescribed Wells Area Well Investigation Project’ for the Northern Adelaide and Barossa Catchment Water Management Board (NABCWMB). This report provides an overview of the issues, results to date and future directions for the project. Stage 1 of the Leaky Wells Project is designed to audit and compile an accurate list of licensed irrigation wells within the Northern Adelaide Plains (NAP) Prescribed Wells Area (PWA). Of these licensed wells pumped salinity samples were to be collected by the licence holder and submitted for analysis. From a review of these wells and recorded salinity information all wells determined to be contaminating the major production aquifers were to be identified, investigated and remedial action undertaken. Stage 2 of the Leaky Wells Project aimed to assess the condition of the 2868 abandoned and disused wells throughout the NAP. As mentioned in the Administrative Agreement, it was expected that this phase of the project would be the most intensive, requiring considerable field investigations to determine the locations and current condition of these wells.

description: We present lattice QCD results for masses and magnetic polarizabilities of light and strange pseudoscalar mesons, chiral condensates, decay constants of neutral pion, and neutral kaon in the presence of background magnetic fields with $eB$ ranging up to around 3.35 GeV$^2$ ($\sim70~M_π^2$) in the vacuum. The computations were carried out in (2+1)-flavor QCD mostly on $32^3 \times 96$ lattices using the highly improved staggered quark action with $M_π \approx $ 220 MeV at zero temperature. We find that the masses of neutral pseudoscalar mesons monotonously decrease as the magnetic field strength grows and then saturate at a nonzero value, while there exists a nonmonotonous behavior of charged pion and kaon masses in the magnetic field. We observe a $qB$ scaling of the up and down quark flavor components of neutral pion mass, neutral pion decay constant as well as the quark chiral condensates at 0.05 $\lesssim eB\lesssim$ 3.35 GeV$^2$. We show that the correction to the Gell-Mann-Oakes-Renner relation involving the neutral pion is less than 6% and the correction for the relation involving neutral kaon is less than 30% at $eB\lesssim$ 3.35 GeV$^2$. We also derive the Ward-Takahashi identities for QCD in the magnetic field in the continuum formulation including the relation between integrated neutral pseudoscalar meson correlators and chiral condensates.

description: In many tropical regions, cassava is a major food source, especially for subsistence farmers. It is high in carbohydrates and very productive in semi-arid regions and poor, acid soils. Production of cassava has consistently increased in recent years, but post-harvest deterioration continues as a major obstacle to its greater commercialization. Over 40 introduced and local cultivars were planted at Isabela, Puerto Rico, to determine post-harvest losses as influenced by fungicide treatment, cultivar, and storage time. Root deterioration was rated at four and 16 days after harvest using the CIAT scale. Hydrogen cyanide (HCN} content was determined at harvest; and dry matter content and culinary quality were measured at harvest and on the two-post harvest dates. Before storage, roots were either not treated or submerged in 4,000 ppm thiabendazole in aqueous solution. Some of the introduced cultivars showed superior storage and culinary qualities compared to the Puerto Rican commercial cultivars evaluated. Resistant cultivars and fungicide treatment were highly effective in delaying post-harvest deterioration. When treated with fungicide, 10 cultivars had maintained less that 5% root deterioration at 16 days after harvest. Pl 12903 had outstanding culinary quality even after 16 days' storage. Only Brava and Pl 9608 contained dangerously high levels of HCN, exceeding 115 ppm.
Allelopathic influence of tall hedge mustard (Sisymbrium loeselii L.) and spotted knapweed (Centaurea maculosa Lam.) on arbuscular mycorrhizal fungi
Creators: name: Bainard, Luke D.
Publisher: name: University of British Columbia

description: Many exotic weeds interfere with other species by releasing allelochemicals into the environment that have a negative effect on their growth and distribution. Allelochemicals can have a direct influence on plant growth and/or indirect influence by disrupting interactions between plants and soil organisms, such as arbuscular mycorrhizal (AM) fungi. The goal of this research was to explore the allelopathic influences of the exotic weeds tall hedge mustard (Sisymbrium loeselii L.) and spotted knapweed (Centaurea maculosa Lam.). The allelopathic potential of tall hedge mustard was assessed using aqueous root and shoot extracts in seed germination and seedling growth bioassays. Aqueous tall hedge mustard root and shoot extracts strongly inhibited germination and growth of bluebunch wheatgrass, Idaho fescue, and spotted knapweed. Glucosinolate (GSL) analysis of tall hedge mustard tissues revealed the presence of two major GSLs (isopropyl GSL and sec-butyl GSL) and four indolylic GSLs. The degradation products of the two major GSLs (isopropyl isothiocyanate [ITC] and sec-butyl ITC) were identified in tall hedge mustard aqueous root and shoot extracts. Commercially available isopropyl ITC and sec-butyl ITC inhibited seed germination and seedling growth, suggesting their role in the allelopathic influence of tall hedge mustard. Tall hedge mustard aqueous extracts and ITCs incorporated into an agar medium inhibited Glomus intraradices Shenck & Smith spore germination and hyphal growth. Tall hedge mustard aqueous extracts strongly inhibited spore germination and hyphal growth of G. intraradices. Isopropyl ITC and sec-butyl ITC inhibited spore germination and hyphal growth, with the former exhibiting a stronger effect. Tall hedge mustard infestations were also found to reduce the A M inoculum potential of soil. The A M colonization and total biomass was reduced in bluebunch wheatgrass and spotted knapweed plants growing in tall hedge mustard infested compared to noninfested soil. Spotted knapweed is known to produce two major allelochemicals, (±)-catechin and cnicin. Both allelochemicals inhibited Glomus intraradices spore germination, and cnicin also inhibited the hyphal growth, suggesting that these allelochemicals may be involved in the inhibitory effect spotted knapweed has on A M fungi. Results of this study show that tall hedge mustard and spotted knapweed both produce allelochemicals that have the potential to directly and/or indirectly inhibit the growth of neighboring species and their A M fungal associates.

description: We examine the nucleosynthesis products that are produced in the outflow from rapidly accreting disks. We find that the type of element synthesis varies dramatically with the degree of neutrino trapping in the disk and therefore the accretion rate of the disk. Disks with relatively high accretion rates such as 10 M_solar/s can produce very neutron rich nuclei that are found in the r process. Disks with more moderate accretion rates can produce copious amounts of Nickel as well as the light elements such as Lithium and Boron. Disks with lower accretion rates such as 0.1 M_solar/s produce large amounts of Nickel as well as some unusual nuclei such as Ti-49, Sc-45, Zn-64, and Mo-92. This wide array of potential nucleosynthesis products is due to the varying influence of electron neutrinos and antineutrinos emitted from the disk on the neutron-to-proton ratio in the outflow. We use a parameterization for the outflow and discuss our results in terms of entropy and outflow acceleration.

description: The standard Murashige and Skoog (1962) culture medium was proven effective for initiation of meristem in cultures of cocoyam (tannia; Xanthosoma sagittifolium cv. Rabess) but was found not to be so useful for plantlet regeneration. However, when cultures at 6-8 weeks old were transferred to an amended medium /with the exclusion of benzylaminopurine (BAP)/ calli formation was high along with organogenesis, resulting in extensive shoot and root development. Plantlet regeneration from meristems was achieved within 16-20 weeks. There was no significant variation in plant morphology of plantlets regenerated using this two-step production system.

description: Understanding the spectrum of noise acting on a qubit can yield valuable information about its environment, and crucially underpins the optimization of dynamical decoupling protocols that can mitigate such noise. However, extracting accurate noise spectra from typical time-dynamics measurements on qubits is intractable using standard methods. Here, we propose to address this challenge using deep learning algorithms, leveraging the remarkable progress made in the field of image recognition, natural language processing, and more recently, structured data. We demonstrate a neural network based methodology that allows for extraction of the noise spectrum associated with any qubit surrounded by an arbitrary bath, with significantly greater accuracy than the current methods of choice. The technique requires only a two-pulse echo decay curve as input data and can further be extended either for constructing customized optimal dynamical decoupling protocols or for obtaining critical qubit attributes such as its proximity to the sample surface. Our results can be applied to a wide range of qubit platforms, and provide a framework for improving qubit performance with applications not only in quantum computing and nanoscale sensing but also in material characterization techniques such as magnetic resonance.

description: We study the evolution of the network properties of a populated network embedded in a genotype space characterised by either a low or a high number of potential links, with particular emphasis on the connectivity and clustering. Evolution produces two distinct types of network. When a specific genotype is only able to influence a few other genotypes, the ecology consists of separate non-interacting clusters in genotype space. When different types may influence a large number of other sites, the network becomes one large interconnected cluster. The distribution of interaction strengths -- but not the number of connections -- changes significantly with time. We find that the species abundance is only realistic for a high level of species connectivity. This suggests that real ecosystems form one interconnected whole in which selection leads to stronger interactions between the different types. Analogies with niche and neutral theory are also considered.

description: The paleosols of the Last Interglacial are presented in many loess sequences of the European temperate zone by soils with Argic horizon, that are considered to be the pedological response to the bioclimatic conditions of that period. We studied micromorphological, physical/chemical (bulk chemical composition, texture and dithionite-extractable iron) and mineralogical characteristics of two profiles – an Eemian Luvisol in Upper Austria (Oberlaab) and a Mikulino Albeluvisol in Central Russia (Alexandrov Quarry near Kursk) to compare them with recent analogous soils and to make further paleoecological and chronological inferences. Both profiles showed a set of characteristics indicative for weathering of primary minerals, clay transformation illuviation and surface redoximorphic (stagnic) processes. Paleosols demonstrate more advanced development than the Holocene analogues manifested however in different pedogenetic characteristics. The Eemian Luvisol in Upper Austria is characterized by stronger clay illuviation manifested in higher clay content and abundance of illuvial clay pedofeatures in the Bt horizon. Mikulino Albeluvisol in Central Russia is more strongly affected by eluvial and stagnic processes evidenced by deeper and more intensive accumulation of bleached silty material and clay depletion. We suppose that the properties of parent material are responsible for these differences. Russian Albeluvisol is formed on the Dnepr loess poor in weatherable minerals and having limited capacity for buffering acidity and clay formation. The higher development status of the Last Interglacial paleosols compared to the Holocene soils having however same type pedogenesis implies longer soil formation period, that agree with some of the paleobotanical proxies and could include besides MIS 5e part of MIS 5d; the warmer and moister paleoclimate during MIS 5e could also account for more advanced paleosol development Several phases of clay illuviation interrupted by frost structuring and deformation are detected in the Eemian Bt horizon in Upper Austria. It suppose even longer development that could extend to the Early Würmian interstadials (late substages of MIS5).

Evolution of the Structure Factors in Pure SU(N) Lattice Gauge Theory and Effective Spin Models

description: We consider model A dynamics for a quench from the disordered into the ordered phase of SU(3) lattice gauge theory and the analogue 3d 3-state Potts model. For the gauge model this corresponds to a rapid heating from the confined to the deconfined phase. The exponential growth factors of low-lying structure function modes are numerically calculated. The linear theory of spinodal decomposition is used to determine the critical modes. This allows for the Debye screening mass estimation in an effective phenomenological model. The quench leads to competing vacuum domains, which make the equilibration of the QCD vacuum after the heating non-trivial. The influence of such domains on the gluonic energy density is studied.

description: We have studied the superconducting-insulating phase transition in a disordered two-dimensional Josephson junction array, using quantum Monte Carlo techniques. We consider disorder in both the capacitive energies and in the values of the offset charges. The calculated phase diagram shows that the lobe structure of the phase diagram disappears for sufficiently strong disorder in the offset charge. Our results agree quite well with previous calculations carried out using a mean-field approximation.

The effects of American scientific communities and industry on US chemical & biological weapons policy
Creators: name: Winzoski, Karen Jane
Publisher: name: University of British Columbia
Year: 2011

description: This thesis examines the effects that scientific communities and domestic industry have had on US chemical and biological weapons policy over the last forty years, and in particular their influence in the successful ratification of the Chemical Weapons Convention (CWC) in 1997, and the US rejection of the proposed verification protocol for the Biological Weapons Convention (BWC) in 2001. To explore the interaction of scientific communities, industry and government, scientific and industrial publications from 1965 to 2006 were systematically researched, and interviews were conducted with individuals from academia, industry and government who were directly involved with the formulation of US chemical and biological weapons policy. This thesis concludes that scientists have at times exerted considerable influence over US chemical weapons policy. Furthermore, concerted efforts in support of chemical disarmament on the part of the US chemical industry made a tremendous contribution towards the success of the CWC. It also concludes that even though the microbiology community had a significant impact on US biological weapons policy in the 1960s, the biotech revolution split the microbiology community into two competing factions, and decreased the influence of scientists who continued to lobby for arms control. Furthermore, this study finds that although the pharmaceutical and biotech industry is frequently blamed for the failure of the BWC verification protocol, in reality it played a minor role in this decision. Several of this study's findings have implications for International Relations theories that examine how and why arms control regimes emerge, in particular the epistemic communities and Military-Industrial Complex literatures. Consistent with Matthew Evangelista's analysis of the effects of international epistemic communities on Soviet nuclear policy, this study demonstrates that scientists are most influential when they develop personal relationships with high-ranking policymakers, particularly the head of state. Perhaps this study's most original theoretical finding is that although corporations involved with defence are invariably assumed to be motivated solely by their own financial interests, even by non-rationalist theories, these industries can pursue more enlightened ends. Thus, this study opens a door for International Relations scholars to think of defence industry interests as politically interesting.

description: Scott Creek Catchment is the first of a number of catchments that will be used as case studies to investigate the sustainability of groundwater resources in the Mount Lofty Ranges over the next 45 years. This report provides a collation of background information for the Scott Creek Catchment including geological, hydrological, meteorological and surface water quality data. Site selection criteria, drilling methods, construction details and lithological logs are presented for the first phase of drilling in this catchment. A total of nine wells (one completed in the Quaternary alluvium and eight in the fractured Woolshed Flat Shale) were drilled at strategic locations on either side of Scott Creek upstream of the weir at Scott Bottom. These wells will be used for a variety of hydraulic and hydrochemical tests to define the local hydrogeology in terms of streamaquifer interactions and groundwater recharge and flow rates.

Fragility and compressibility at the glass transition

description: Isothermal compressibilities and Brillouin sound velocities from the literature allow to separate the compressibility at the glass transition into a high-frequency vibrational and a low-frequency relaxational part. Their ratio shows the linear fragility relation discovered by x-ray Brillouin scattering [1], though the data bend away from the line at higher fragilities. Using the concept of constrained degrees of freedom, one can show that the vibrational part follows the fragility-independent Lindemann criterion; the fragility dependence seems to stem from the relaxational part. The physical meaning of this finding is discussed. [1] T. Scopigno, G. Ruocco, F. Sette and G. Monaco, Science 302, 849 (2003)

description: The influence of calcite, dolomite, pyrite and vaterite on the kinetics of uranium (U) release from a natural rock under relevant i.e. field conditions has been investigated. The time dependence of the U release has been studied in two different experimental procedures (open and closed systems) at laboratory temperature (21 ± 2 ʿC). Performing batch experiments in tap water, the U release efficiency of a natural U-bearing rock was characterised in the presence of varying amounts of three different carbonate bearing minerals for experimental durations of up to 782 days. Another experiment was conducted for a period of 14 days in the presence of a pyrite mineral. The results demonstrate that the presence of carbonate minerals does not have any significant influence on U release in closed systems where the U concentration at saturation was ca. 54 mg/L. In contrast, in open systems, the U concentration was ca. 8 mg/L at saturation and the effects of all additives both on kinetics and saturation concentration of U were apparent.

description: Precise predictions are provided for the production of a $\mathrm{Z}$-boson and a $\mathrm{b}$-jet in hadron-hadron collisions within the framework of perturbative QCD, at $\mathcal{O}(α_s^3)$. To obtain these predictions we perform the first calculation of a hadronic scattering process involving the direct production of a flavoured-jet at next-to-next-to-leading order accuracy in massless QCD, and extend techniques to also account for the impact of finite heavy-quark mass effects. The predictions are compared to CMS data obtained in $\mathrm{pp}$ collisions at a centre-of-mass energy of $8~\mathrm{TeV}$, which are the most precise data from Run I of the LHC for this process, where a good description of the data is achieved. To allow this comparison we have performed an unfolding of the data, which overcomes the long-standing issue that the experimental and theoretical definitions of jet flavour are incompatible.

description: This paper is based on research with two groups of novice and expert teachers with and without TEFL Certificate (Standard Licensed and Alternatively Licensed) in contexts with prescribed methodology. It considers discord and tensions between teachers’ preformed beliefs, prior experiences and conceptions of teaching with the contextual obligations and teaching practices which may result in cognitive dissonance. In addition, it attempts to understand how teachers’ dispositions as indicated through teaching practices could affect them with various professional profiles such as expertise and teaching licensure. Associated with this, the article also studies how awareness and experience of dissonance in different teachers may be reflective of a ‘change provoking disequilibrium’ which may affect and shift their cognition and quality of their teaching. Cognitive Dissonance questionnaire (DARQ), class observation, and semi-structured interviews are used to help explain to what extent teachers experience and respond to dissonance during their field experiences and professional development.
Thermodynamic uncertainty relation for time-dependent driving

Year: 2020
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: Thermodynamic uncertainty relations yield a lower bound on entropy production in terms of the mean and fluctuations of a current. We derive their general form for systems under arbitrary time-dependent driving from arbitrary initial states and extend these relations beyond currents to state variables. The quality of the bound is discussed for various types of observables for an interacting pair of colloidal particles in a moving laser trap and for the dynamical unfolding of a small protein. Since the input for evaluating these bounds does not require specific knowledge of the system or its coupling to the time-dependent control, they should become widely applicable tools for thermodynamic inference in time-dependently driven systems.

description: The crystal structure and phonon dynamics of pentacene is computed with the Quasi Harmonic Lattice Dynamics (QHLD) method, based on atom-atom potential. We show that two crystalline phases of pentacene exist, rather similar in thermodynamic stability and in molecular density. The two phases can be easily distinguished by Raman spectroscopy in the 10-100 cm-1 spectral region. We have not found any temperature induced phase transition, whereas a sluggish phase change to the denser phase is induced by pressure. The bandwidths of the two phases are slightly different. The charge carrier coupling to low-frequency phonons is calculated.

description: The first stars in the Universe, the so-called Population III stars, form in small dark matter minihaloes with virial temperatures $T_{\rm vir} < 10^{4}$~K. Cooling in these minihaloes is dominated by molecular hydrogen (H$_{2}$), and so Population III star formation is only possible in those minihaloes that form enough H$_{2}$ to cool on a short timescale. As H$_{2}$ cooling is more effective in more massive minihaloes, there is therefore a critical halo mass scale $M_{\rm min}$ above which Population III star formation first becomes possible. Two important processes can alter this minimum mass scale: streaming of baryons relative to the dark matter and the photodissociation of H$_{2}$ by a high redshift Lyman-Werner (LW) background. In this paper, we present results from a set of high resolution cosmological simulations that examine the impact of these processes on $M_{\rm min}$ and on $M_{\rm ave}$ (the average minihalo mass for star formation), both individually and in combination. We show that streaming has a bigger impact on $M_{\rm min}$ than the LW background, but also that both effects are additive. We also provide fitting functions quantifying the dependence of $M_{\rm ave}$ and $M_{\rm min}$ on the streaming velocity and the strength of the LW background.
