description: Sunflower research in North Dakota focuses on variety testing. Additional research has been conducted on cost-effective cultural practices, possible use to produce a red dye food colorant, and the estimated economic impact of banning an insecticide. Variety testing has been conducted at most state experiment sites in North Dakota, including, Casselton Agronomy Seed Farm, Carrington Research Extension Center, Langdon, Minot, Williston, Dickinson, and Hettinger Experiment Stations. A comparison of the impact of conventional tillage and no tillage on sunflower in North Dakota has been conducted at Dickinson Experiment Station and USDA-ARS Northern Great Plains Research Laboratory, Mandan. A large number of diseases and pests may infect sunflower. The North Dakota State University Entomology Department and the state experiment stations have ongoing research directed at meeting the problems producers face. The Department of Agricultural Economics and the Department of Food and Nutrition at North Dakota State University have investigated the feasibility of extracting a red food colorant from the hulls of purple-hulled sunflower. The Department of Agricultural Economics has estimated the impacts of banning methyl parathion application on sunflower.

Wigner-Poisson and nonlocal drift-diffusion model equations for semiconductor superlattices

Year: 2005
Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: A Wigner-Poisson kinetic equation describing charge transport in doped semiconductor superlattices is proposed. Electrons are supposed to occupy the lowest miniband, exchange of lateral momentum is ignored and the electron-electron interaction is treated in the Hartree approximation. There are elastic collisions with impurities and inelastic collisions with phonons, imperfections, etc. The latter are described by a modified BGK (Bhatnagar-Gross-Krook) collision model that allows for energy dissipation while yielding charge continuity. In the hyperbolic limit, nonlocal drift-diffusion equations are derived systematically from the kinetic Wigner-Poisson-BGK system by means of the Chapman-Enskog method. The nonlocality of the original quantum kinetic model equations implies that the derived drift-diffusion equations contain spatial averages over one or more superlattice periods. Numerical solutions of the latter equations show self-sustained oscillations of the current through a voltage biased superlattice, in agreement with known experiments.

description: We derive the long-wavelength non-linear sigma model for a two-dimensional Heisenberg system in the presence of the Dzyaloshinskii-Moriya and pseudodipolar interactions. We show that the system is a non-conventional easy-axis antiferromagnet, displaying an anomalous coupling between the magnetic field and the staggered order parameter. Our results are in good agreement with recent experimental data for undoped La2CuO4 compounds.

description: Traditionally, the family farm has always been seen as a cornerstone of the agricultural production system. Given social, economic and political evidence (Calus, 2009), this organisational form might still continue to shape agricultural development. However, important changes in social and economic environment (e.g. industrialisation of agriculture, increased risk level and public vision on agriculture) become threats to the traditional model. A SWOT analysis of the family farms indicates the various intrinsic characteristics that make family farms resilient to changing conditions. Even in a changing economic and social landscape these aspects provide them with building blocks for creating new organisational forms or institutional arrangements. This paper shows these building blocks, and is only, prudentially, indicative for possible new institutional arrangements. Creativity may produce numerous outcomes from building blocks. Land tenure is only one example from past and present to show how institutions can deal with a potential threat, such as the large demand for land as production factor. Similar creativity is needed to the exploding capital demand in agriculture. One of the major challenges will be to provide family farms with low-costing capital. Food security and local community viability is the social price for this low cost supply.

description: We show that in the multi-terminal ballistic devices with intrinsic spin-orbit interaction connected to normal metal contacts there are no equilibrium spin currents present at any given electron energy. Obviously, this statement holds also after the integration over all occupied states. Based on the proof of this fact, a number of scenarios involving nonequilibrium spin currents is identified and further analyzed. In particular, it is shown that an arbitrary two-terminal device cannot polarize transient current. The same is true for the output terminal of an N-terminal device when all N-1 inputs are connected in parallel.

description: Indian agriculture is characterized by the predominance of smallholders. This paper seeks to examine the access of small holders to agriculture credit in the context of financial sector reforms in India in the nineties. It explores the role of institutional and non institutional agencies in extending agriculture credit to the smallholder and the ground realities as revealed by recent data sets. The nineties also saw the unfolding of the largest microfinance programme in the world in India. While this was very successful in bringing micro enterprises under the credit purview, it was unable to cater to the need for agriculture credit. This paper examines the reasons for this and suggests that newer kinds of institutional innovations in the Pilot stage like, Joint Liability Groups, VDC- Farmers Club Model, SHG-Contract Farming Linkage model which seek to overcome the difficulties faced by smallholders in accessing agriculture credit are effective. They need to be upscaled and mainstreamed in order to bring about vibrancy in the rural credit market in India.
Accelerating process development of recombinant protein production in perfusion cultures of Chinese hamster ovary cells
Creators: name: Angepat, Sumitra
Publisher: name: University of British Columbia
Year: 2009

description: Perfusion processes provide high productivity, low product residence times and consistent culture conditions, but require long process development times. It can require a week or more to reach each steady state result for process optimization, slowing process development and causing increased production cost. The objective of this work was to accelerate process development in perfusion cultures. Recombinant CHO cells producing t-PA were used, and the effects of temperature, pH and dissolved oxygen were investigated in pseudo steady state perfusion cultures at ~10 cells/mL. It was found that the t-PA concentration increased over 50% at temperatures lower than 37 °C, with concentrations over 200 mg/L produced at 33 °C. Cell specific t-PA productivity also increased at low temperatures, reaching a maximum at 33 °C. A low DO concentration of 16% air saturation had a detrimental effect on t-PA productivity and concentration compared to 70%, while 100% air saturation had no significant effect. Cell specific t-PA production and titre were also negatively affected by pH values < 6.85. To decrease the time needed to achieve steady state, a method to use non-steady state transient responses was developed to qualitatively predict steady state production performance. The method was tested using 3 day temperature shifts in perfusion cultures scanned down by 2 °C from 37 °C to 31 °C, then scanned up to 37 °C. Transient results showed that higher t-PA concentrations could be predicted at lower temperatures, as pseudo steady state results confirmed. In most cases, transient values on the 3rd day were also in close concordance with pseudo steady state values. To further accelerate process development, transient scanning was applied to small scale, non-instrumented cultures. Similar results were produced, although quantitative t-PA values were 15-30 times lower than in perfusion culture. The method was further refined by investigating 1 day transient shifts in temperature. More variability was observed in the 1 day transient response, suggesting that cells are still adapting to the new environment, but the overall response still qualitatively predicted the pseudo steady state results. By using a 1 day transient scanning method in small scale culture, process development time could be reduced by as much as 90% when compared to steady state evaluation.

description: This paper examines the consequences of the transformations of extension services for small scale farms. It presents the results of investigations embedded in regulation theory, which combine a comparative institutional analysis, statistical data processing (national agricultural census) and direct surveys. We describe the transformations in the EU and show that they make it more difficult for small farms to access extension services and to benefit from “front office” support (i.e. direct advice from extensionists). Finally, we emphasize that due to the modification of the knowledge production regime, these small farms may also suffer new specific adverse effects resulting from the re-organization of the "back-office" R&D activities of these extension services (i.e. knowledge base updating, database building, scientific experiments, etc.).

description: We find hydrodynamic behavior in large simply spinning five-dimensional Anti-de Sitter black holes. These are dual to spinning quantum fluids through the AdS/CFT correspondence constructed from string theory. Due to the spatial anisotropy introduced by the angular momentum in the system, hydrodynamic transport coefficients split into one group longitudinal and another transverse to the angular momentum. Analytic expressions are provided for the two shear viscosities, the longitudinal momentum diffusion coefficient, two speeds of sound, and two sound attenuation coefficients. Known relations between these coefficients are generalized to include dependence on angular momentum. The shear viscosity to entropy density ratio varies between zero and 1/(4$π$) depending on the direction of the shear. These results can be applied to heavy ion collisions, in which the most vortical fluid was reported recently. In passing, we show that large simply spinning five-dimensional Myers-Perry black holes are perturbatively stable for all angular momenta below extremality.

description: The objective of the paper is to find out the position and perspectives of small farms’ production sales with respect to the structure development of subsequent vertical stage. Structure development is evaluated in terms of company’s size, which is defined according to the number of the persons employed. The analysis is based on the assumption that small farms are able to sell their production rather to small than big processors and the question is whether the small processors give stability and certainty for small farms. The paper deals with chosen commodity chains in the Czech Republic. As an example of the variability in the food industry there were chosen two processing sectors that are important processors of diverse commodity sources of production and with different structural characteristics which was mainly affected by divergent development during consolidation process in the Czech Republic. The main methodical approach is based on the share of value added which is as the indicator of performance showing the rate of production factor usage (input) on the final production (output) and on the turnover produced. Furthermore other indicators of financial situation are evaluated by the Spider Analysis of particular size groups of processors.

description: This paper investigates various modes of vertical coordination, with the focus on small farm integration in the Romanian dairy chain. It draws on results from a World Bank study based on semi-structured interviews conducted in spring 2009. The findings indicate that large and prosperous dairy chains fortify their chain efficiency by partner selection and provision of sophisticated assistance to relatively larger farmers. On the contrary, many barriers exist for small and medium-sized dairy chains (processors and farmers). The main factors hampering their potential exploitation are restricted access to inputs markets (capital, know-how) as well as poor quality of input service (agricultural service delivery, veterinary issues). The majority of cow's milk in Romania is still delivered by small farmers who have difficulties fulfilling the requirements of the modern procurement systems. However, small farmers are a relatively heterogeneous group. Hence, different development paths can be expected. In addition to working with retail chains via strengthening horizontal integration, another opportunity for small dairy farmers is to occupy a market niche. Nevertheless, some small farmers will have to leave the dairy market.

description: We derive hamiltionian generators of asymptotic symmetries for general relativity with asymptotic AdS boundary conditions using the ``covariant phase space'' method of Wald et al. We then compare our results with other definitions that have been proposed in the literature. We find that our definition agrees with that proposed by Ashtekar et al, with the spinor definition, and with the background dependent definition of Henneaux and Teitelboim. Our definition disagrees with the one obtained from the ``counterterm subtraction method,'' but the difference is found to consist only of a ``constant offset'' that is determined entirely in terms of the boundary metric. We finally discuss and justify our boundary conditions by a linear perturbation analysis, and we comment on generalizations of our boundary conditions, as well as inclusion of matter fields.

Tidal dissipation in evolving low-mass and solar-type stars with predictions for planetary orbital decay

description: We study tidal dissipation in stars with masses in the range $0.1-1.6 M_\odot$ throughout their evolution, including turbulent effective viscosity acting on equilibrium tides and inertial waves in convection zones, and internal gravity waves in radiation zones. We consider a range of stellar evolutionary models and incorporate the frequency-dependent effective viscosity acting on equilibrium tides based on the latest simulations. We compare the tidal flow and dissipation obtained with the conventional equilibrium tide, which is strictly invalid in convection zones, finding that the latter typically over-predicts the dissipation by a factor of 2-3. Dissipation of inertial waves is computed using a frequency-averaged formalism accounting for realistic stellar structure for the first time, and is the dominant mechanism for binary circularization and synchronization on the main sequence. Dissipation of gravity waves in the radiation zone assumes these waves to be fully damped (e.g.~by wave breaking), and is the dominant mechanism for planetary orbital decay. We calculate the critical planetary mass required for wave breaking as a function of stellar mass and age, and show that this mechanism predicts destruction of many hot Jupiters but probably not Earth-mass planets on the main sequence. We apply our results to compute tidal quality factors following stellar evolution, and tidal evolutionary timescales, for the orbital decay of hot Jupiters, and the spin synchronization and circularization of binary stars. We also provide predictions for shifts in transit arrival times due to tidally-driven orbital decay of hot Jupiters that may be detected with NGTS, TESS or PLATO.

description: The paper investigates the choice between conventional and organic production technologies for individual farmers in Hungarian agriculture. We employ sequential logit model on a cross-section data set of Hungarian farmers for the period 2007. Our estimations reveal that age of farmers has negative, whilst being full time farmers and having more diversified production structure have positive impact on the intention for being organic farmers. Furthermore, it appears that education, being full time farmers and more diversified production structure positively influence the final decision between conventional and organic farming.

The effect of surface properties of Boron Nitride on polymer processability
Creators: name: Rathod, Nimish
Publisher: name: University of British Columbia
Year: 2009

description: In commercial polymer processing operation such as extrusion, film blowing and blow molding, product quality and production rate are limited by the appearance of flow instabilities. This flow instability is manifested as distortions on the extrudate surface (melt fracture), usually observed at high production rates. Fluoropolymers have long been used as processing aids for surface melt fracture treatment of polyolefin extrudates. Recent developments have shown that a small amount of Boron Nitride (BN) powder successfully eliminates surface melt fracture and also delays the onset of gross melt fracture. It is also observed that a combination of BN and Fluoropolymer enhances the performance of the extrusion even further. The main objective of the present work is to estimate surface properties of BN mainly surface energy and adsorption capacity to understand its influence in the performance of different grades of BN as processing aids. Based on this study, it can be concluded that surface energy plays a very important role in deciding the possible interaction between the processing aid, polymer melt and the extruding surface. It is observed that lubricious nature of BN along with an optimum balance of surface energy and polarity makes BN (grades: AS 612 and CTF5) successful in both sharkskin as well as gross melt fracture regions.

Evaluations of model wave functions may be done with analyses of elastic and inelastic scattering from hydrogen. Those require a realistic model of nucleon-nucleus scattering as scattering from hydrogen translates to proton scattering in the inverse kinematics. The Melbourne g-folding model for intermediate energy is presented along with various examples. Implications for existing and future experimental and theoretical work are discussed.

In contrast to the usual situation, kinetic mixing is forbidden by the symmetry and the dark photon interacts with the Standard Model photon only via an axion-like particle acting as a "messenger". Focusing on signatures involving the ordinary photon, our survey of the phenomenology includes limits from cosmological stability, CMB distortions, astrophysical energy loss, light-shining-through-walls experiments, helioscopes and solar X-ray observations.

description: Rural non-farm employment (RNFE) is thought to curtail increases in rural poverty and income inequality. In the Croatian context three key questions arise: (1) Does the uptake of alternative employment actually help to raise the welfare of small family farms? (2) How is the rural income distribution affected by mixed income structures? (3) Will non-farm diversification rather trigger farm exit or inhibit structural change because a large number of tiny farms persist? In this paper we present results on the effect of RNFE on the income structure and inter-household income distribution among Croatian family farms. The analysis draws on a survey of 175 randomly selected family farms in two Croatian regions in 2007. The poorest farm households have little access to land, and – although dependent on farming incomes they cannot live from agriculture alone. The better-off farms receive significantly higher incomes per hectare of land. RNFE affects rural livelihoods positively in two ways: it is the most important income source of middle income farms, and is found to be an important catalyst that helps smoothing income inequality in the rural context.

description: Although Greece is one of the older Member States of the European Union, its agricultural structures have not followed the same evolution compared to those of other Western European countries. In the majority of the latter, the number of farms and farmers has declined subsequently to the modernisation movement, while Greek agriculture has maintained a high number of farms and farmers. The Greek case can be considered as a paradigm between two EU country groups: the old and the new Member States. This paper deals with the reasons leading to this phenomenon: how do Greek farms manage to resist to an increasingly liberalised environment and to the reduction of EU and State financial support? Why do young people go on dealing with agriculture? This is a curious fact given the hostile natural environment, the low productivity and intensification of these farms. Moreover, this paper deals with some other questions relevant to the ways small farms function and contribute to landscape planning, environmental management and sustainable development of rural areas in general. Finally, some scenarios are developed about the future of European agriculture in the context of forthcoming changes that result from the CAP reform and liberalisation.

description: The dynamics of several light filaments (spatial optical solitons) propagating in an optically nonlinear and non-local random medium is investigated using the paradigms of the physics of complexity. Cluster formation is interpreted as a dynamic phase transition. A connection with the random matrices approach for explaining the vibrational spectra of an ensemble of solitons is pointed out. General arguments based on a Brownian dynamics model are validated by the numerical simulation of a stochastic partial differential equation system. The results are also relevant for Bose condensed gases and plasma physics.

description: Associative polymers with sticker-and-spacer architectures undergo phase transitions that combine phase separation and bond percolation. Here, we generalize mean-field models for bond percolation and extract effective sticker interaction strengths from experimental data for specific proteins. We use graph-based Monte Carlo simulations to evaluate effects ignored by mean-field models. These include bond cooperativity defined as changes to strengths of new bonds (physical crosslinks) given the presence of a prior bond. We find that bond cooperativity fundamentally alters phase behavior, especially in sub-stoichiometric regimes for valencies of complementary stickers.

description: We present results from analysis of the observation of the dipping, quasi-periodic bursting LMXB XB 1323-619 made with XMM-Newton in Jan., 2003. A number of absorption lines were discovered in the spectrum, notably at 6.70 and 6.98 keV which we identify with scattering by ions Fe XXV and Fe XXVI. Such features have been seen in other dipping sources, but their origin has not been understood. Curve of growth analysis provided a consistent solution assuming collisional ionization with kT=45 keV, close to the electron temperature we previously determined for the ADC in this source. We thus propose that the absorption lines in the dipping LMXB are produced in the ADC. Spectral evolution in dipping was well-described by the progressive covering model which we have previously shown to give very good explanations of many dipping sources. We discuss the proposal of Boirin et al. (2004b), that spectral evolution in the dipping LMXB may be explained by subjecting the continuum to a highly ionized absorber. This would require a decrease in X-ray intensity by a factor of ~3 in dipping at energies where photoelectric absorption is not effective (40-100 keV) which previous analysis of BeppoSAX data on several sources rules out, e.g. in XB 1323-619, any decrease was less than 10+/-10%. We find a remarkable linear increase in the rate of X-ray bursts with time over the 14-year period since 1989, and a systematic non-linear increase in source luminosity (L). The linear variation of burst rate with L shows that the burst rate is proportional to mass accretion rate, and if continued implies that the gap between bursts will become zero on January 11, 2008. In reality we expect the source to undergo a transition from X-ray bursting to X-ray flaring confirming that flaring is unstable nuclear burning.

description: We develop an effective field theory for lattice models, in which the only non-vanishing diagrams exactly reproduce the topology of the lattice. The Bethe-Peierls approximation appears naturally as the saddle point approximation. The corrections to the saddle-point result can be obtained systematically. We calculate the lowest loop corrections for magnetisation and correlation function.

description: The Facility for Antiproton and Ion Research (FAIR) in Darmstadt will provide unique research opportunities for the investigation of fundamental open questions related to nuclear physics and astrophysics, including the exploration of QCD matter under extreme conditions, which governs the structure and dynamics of cosmic objects and phenomena like neutron stars, supernova explosions, and neutron star mergers. The physics program of the Compressed Baryonic Matter (CBM) experiment is devoted to the production and investigation of dense nuclear matter, with a focus on the high-density equation-of-state (EOS), and signatures for new phases of dense QCD matter. According to the present schedule, the CBM experiment will receive the first beams from the FAIR accelerators in 2025. This article reviews promising observables, outlines the CBM detector system, and presents results of physics performance studies.

A global view on the colliding-wind binary WR 147

description: We present results from a global view on the colliding-wind binary WR 147. We analysed new optical spectra of WR 147 obtained with Gran Telescopio CANARIAS and archive spectra from the Hubble Space Telescope by making use of modern atmosphere models accounting for optically thin clumping. We adopted a grid-modelling approach to derive some basic physical characteristics of both stellar components in WR 147. For the currently accepted distance of 630 pc to WR 147, the values of mass-loss rate derived from modelling its optical spectra are in acceptable correspondence with that from modelling its X-ray emission. However, they give a lower radio flux than observed. A plausible solution for this problem could be if the volume filling factor at large distances from the star (radio-formation region) is smaller than close to the star (optical-formation region). Adopting this, the model can match well both optical and thermal radio emission from WR 147. The global view on the colliding-wind binary WR 147 thus shows that its observational properties in different spectral domains can be explained in a self-consistent physical picture.
