description: A new compound Mn0.9Co0.1Al2O4 nanowires were synthesized by thermal method. The resulting powder samples were characterized by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD). We found that a set of phase transformation occurred during the process. Eventually, five phases including three spinal phases, the corundum (á-Al2O3) and MnO were formed at 1100 °C.As dominant morphology, the cubic galaxite nanowires were identified by X-ray analysis. Moreover, X-ray analysis showed that Mn3O4 and Co3O4 nanoparticles were formed in tetragonal and cubic symmetry respectively. The SEM image revealed that a dominate morphology of product has cubic nanowires shape with an average diameter in range 38–43 nm. Furthermore, we observed that influence of temperature was very important in the nanowire formation process. Electrochemical hydrogen evolution reaction (HER) of synthetic composite was evaluated and the over potential of HER was calculated about 110 mV with low Tafel slope equal to 42 mV dec−1, which was comparable with amounts reported transition metal dichalcogenides with satisfying durability.

description: The transfer matrix of the general integrable open XXZ quantum spin chain obeys certain functional relations at roots of unity. By exploiting these functional relations, we determine the Bethe Ansatz solution for the transfer matrix eigenvalues for the special cases that all but one of the boundary parameters are zero, and the bulk anisotropy parameter is η= iπ/3, iπ/5 ,... In an Addendum, these results are extended to the cases that any two of the boundary parameters {α_-, α_+,β_-, β_+} are arbitrary and the remaining boundary parameters are either ηor i π/2.

description: In February 1962 the Council of the Australian Agricultural Economics Society appointed a sub-committee to report on the present state of farm financial statistics in Australia and to recommend desirable improvements. The aims in calling for this report were twofold: (a) Members of the Society have long felt the need for more comprehensive economic information about Australian agriculture. The adverse movement of prices of farm products in Australia during the last decade has increased the urgency to obtain such data. (b) In view of the possible reorganisation of various statistical series, it was felt that the Society - whose members are major users of farm financial statistics - should outline its views on desirable improvements in this field. The Society's concern in this matter is not the result of any decline in the quantity of data published by the various statistical agencies, but is due rather to the rapid growth in the demand for more comprehensive coverage and increased accuracy.

description: Game theory - aptly described as the scientific approach to poker, business, women and war - has proved to be no cure-all for the conflict situations studied by agricultural economists. Like Marshall, it has had its day. Still, just as in general economics, game theory has provided an alternative framework for the study of a variety of agricultural problems. This paper aims to review these studies. As background, a brief resume of the more important economic theories of decision making in risky situations will first be given, followed by an outline of the pertinent aspects of game theory. Agricultural applications are then considered. A general appraisal - pro and con, past and future - completes the review.

description: Lead sulfide quantum dots (PbS QDs) were decorated onto a graphene surface in a semi-core-shell structure using supercritical ethanol. The temperature of ethanol played significant role in controlling size and agglomeration of QDs as well as the extent of reduction of graphene. Average size of the QDs was estimated by transmission electron microscopy to be around 3.96 nm and by quantum models to be about 4.34 nm. PbS QDs prepared at 330 °C were of high purity, and the yield was 99%. Instrumental and chemical analyses demonstrated formation of a strong bond between PbS QDs and graphene, through a Pb-O-C bridge. UV and photoluminescence measurements along with theoretical considerations revealed that integration of PbS QDs with graphene results in efficient separation of the electron-hole, thus enhancing photo → electric energy conversion. This outcome was further evidenced by comparison of performance of PbS/G in a solar cell, with the performance of pristine PbS QDs.
Cadherin-mediated differentiation and fusion of human trophoblastic cells in vitro

description: The placenta supports fetal growth and development during pregnancy. A key step in human placentation involves the terminal differentiation and fusion of villous cytotrophoblasts to form the multinucleated syncytial trophoblast. To date, the cellular mechanism(s) that mediate this developmental process remain poorly characterized. We have determined that the expression of the calcium-dependent cell adhesion molecule, known as cadherin-11, increases during the terminal differentiation and fusion of villous cytotrophoblasts isolated from the human term placenta, BeWo choriocarcinoma cells cultured in the presence of cyclic AMP, and primary cultures of human extravillous cytotrophoblasts treated with transforming growth factor-β1. These observations led us to hypothesize that cadherin-11 mediates the formation of multinucleated syncytium from mononucleate trophoblastic cells in vitro. As cadherin function is regulated by interactions with the cytoplasmic proteins, known as the catenins, we first examined α-, β-, γ-catenin, and p120ctn expression in primary cultures of human villous cytotrophoblasts. The terminal differentiation and fusion of these trophoblastic cells was associated with a reduction in the expression of these four catenin subtypes. In contrast, α-, β-, γ-catenin, and p120ctn were maintained in non-fusing JEG-3 choriocarcinoma cells. These four catenin subtypes were subsequently immunolocalized to the mononucleate cells but not the multinucleated syncytium present in these trophoblastic cell cultures and the villous cytotrophoblasts of the human placenta. To better define the role(s) of cadherin-11 in the terminal differentiation and fusion of human trophoblastic cells in vitro, we examined the effects of ectopic cadherin- 11 expression on the morphological differentiation of non-fusing JEG-3 cells. Cadherin-11 expression in mononucleate JEG-3 cells promoted the terminal differentiation and fusion of these cells with time in culture. In contrast, a reduction in cadherin-11 expression was capable of inhibiting the formation of multinucleated syncytium in primary cultures of human villous cytotrophoblasts. Collectively, these studies demonstrate a critical role for cadherin-11 in the terminal differentiation and fusion of human mononucleate trophoblastic cells in vitro. These observations further our understanding of the adhesive mechanisms operative during the formation and organization of the human placenta and provide insight into the cell biology of cadherin-11.

description: We prove that multidimensional diffusions in random environment have a limiting velocity which takes at most two different values. Further, in the two-dimensional case we show that for any direction, the probability to escape to infinity in this direction equals either zero or one. Combined with our results on the limiting velocity, this implies a strong law of large numbers in two dimensions.

description: A novel insight into the effect of Pt decoration on electrochemical and photoelectrochemical behavior of TiO2 nanotube arrays (TNA) was developed in this study. TNA samples were prepared via a two-step anodization of a titanium foil and decorated with Pt by a facile photodeposition method. The formation of metallic Pt were confirmed by X-ray photoelectron spectroscopy (XPS). On the basis of our calculations, the localized states and surface states induced by Pt deposition into the bandgap of titania nanotubes, play a dominant role in trapping/detrapping charge carriers and electron transfer to electrolyte. In Pt/TNAs the appropriate electrical connection between Pt nanoparticles and TNA induces sufficiently shallow traps in the vicinity of conduction band edge of TNA which creates a fast lane for electrons toward semiconductor/electrolyte interface and decreases the density of deep trap levels compared to the pristine TNA. However, there is an optimum amount for deposited Pt. Higher amount of optimum Pt can impose the monoenergetic deep trap levels which act as recombination centers.

description: It has previously been shown that ${}^{14}$N NMR spectra can be reliably obtained through indirect detection via HMQC experiments. This method exploits the transfer of coherence between single- (SQ) or double-quantum (DQ) ${}^{14}$N coherences, and SQ coherences of a suitable spin-1/2 'spy' nucleus, e.g., ${}^1$H. It must be noted that SQ-SQ methods require a carefully optimized setup to minimize the broadening related to the first-order quadrupole interaction (i.e., an extremely well-adjusted magic angle and a highly stable spinning speed), whereas DQ-SQ ones do not. In this work, the efficiencies of four ${}^{14}$N excitation schemes (DANTE, XiX, Hard Pulse (HP), and Selective Long Pulse (SLP)) are compared using J-HMQC based numerical simulations and either SQ-SQ or DQ-SQ ${}^1$H-{${}^{14}$N} D-HMQC experiments on L-histidine HCl and N-acetyl-L-valine at 18.8 T and 62.5 kHz MAS. The results demonstrate that both DANTE and SLP provide a more efficient 14N excitation profile than XiX and HP. Furthermore, it is shown that the SLP scheme: (i) is efficient over a large range of quadrupole interaction, (ii) is highly robust to offset and rf-pulse length and amplitude, and (iii) is very simple to set up. These factors make SLP ideally suited to widespread, non-specialist use in solid-state NMR analyses of nitrogen-containing materials.
U.S. WOOL POLICY AND ITS EFFECTS ON APPAREL WOOL IMPORTS

description: The United States occupies a rather unique position in the world wool trade - besides being one of the world's largest apparel wool producers, she also needs to supplement her requirements by sizeable imports from wool surplus countries. However, wool imports into the U.S. have a strong competitive advantage over domestic wools, not only price-wise but also on account of their uniformity and generally better preparation. For this reason the ability of the wool exporting countries to enlarge very substantially their markets in the U.S. by displacing some domestic wools is largely dependent on the American policy of sheltering and fostering the domestic wool industry. For decades, the traditional means of achieving this has been by levying specific tariff duties of varying height on fine apparel wools which proved to be a potential threat to finer Territory (i.e. domestic) grades. Non-competitive carpet wools, on the other hand, imported mainly from Argentina and Uruguay, have been exempt from duty. More recently, with the aim of stimulating wool production to a level compatible with the strategic raw material needs of the U.S., an incentive subsidy program administered by the U.S. Secretary of Agriculture has been superimposed on the existing tariff structure. It is the purpose of this paper to discuss the rationale of the new wool program against the background of the traditional American wool policy, and at a later stage, to explore its implications for American apparel wool imports in general and from Australia in particular.

description: We investigate the Zeeman-field-driven quantum phase transitions between singlet spin liquids and algebraically ordered O(2) nematic spin liquids of spin-one bosons in one-dimensional optical lattices. We find that the critical behavior is characterized by condensation of hardcore bosons instead of ideal magnons in high dimensional lattices. Critical exponents are strongly renormalized by hardcore interactions and critical states are equivalent to the free Fermion model up to the Friedal oscillations. We also find that the algebraically ordered nematic spin liquids close to critical points are fully characterized by the Luttinger liquid dynamics with Luttinger liquid parameters magnetically tunable. The Bethe Ansatz solution has been applied to determine the critical magnetization and nematic correlations.

description: Nickel nanoparticles arrays, growth into hydrogenated amorphous carbon, were prepared by means of RF-plasma enhanced chemical vapor deposition and RF-sputtering co-deposition from acetylene and a nickel target. The resulting nanocomposite films were characterized by X-ray diffraction and atomic force microscopy, and their magnetic responses and magnetoresistance behavior were investigated as a function of the exciting magnetic field and the Ni nanoparticles content, which was conveniently controlled by adjusting the deposition time. These physical properties were explained by a combination of hopping and tunneling effects.

For some black hole parameters we found pure imaginary frequencies. Increasing of the scalar field mass does not cause the imaginary part to vanish, it reaches some minimum and then increases, thus in the case under consideration the infinitely long living modes (quasi-resonances) do not appear.

description: Changes are occurring in the world grain trade that are impacting the spatial distribution of grain flows. Important amongst these are developments in ethanol production in the United States, soybean production in Brazil, and increased imports of soybeans for China. This article develops a spatial optimization model based on a longer-term competitive equilibrium to make projections in the world grain trade and shipments from individual ports to the year 2025. Results indicate that world trade should increase by about 47%, with the fastest growth occurring in imports to China and Pakistan. Japan and the EU, traditionally large markets, have the slowest growth. Most of the increases are expected in soybeans (49%), followed by corn (26%), and most of the U.S. export growth is expected through the U.S. Gulf.

description: Determining surface topography of different tissues of the molar tooth with novel analytical methods has opened new horizons in dental surface measurements which characterize tooth surface quality in dentistry. Studying surface topological measurements and comparing surface morphology of hard tissue of the molar tooth are the ultimate goals of the present study. Ten molar teeth have been chosen for investigating their surface characteristics through image processing techniques. The power spectral density (PSD) and fast Fourier transform algorithms of every molar tooth containing enamel, dentin, and cementum have determined that the characterization of surface profiles is possible. As can be seen, PSD along with fractal dimensions leads to good results for teeth surface topography. Moreover, PSD angular plot assures appropriate description of surface.

description: SHADES is a new, major, extragalactic sub-mm survey currently being undertaken with SCUBA on the JCMT. The aim of this survey is to map 0.5 square degrees of sky at a depth sufficient to provide the first, major (~300 source), unbiased sample of bright (S(850) > 8 mJy) sub-mm sources. Combined with extensive multi-frequency supporting observations already in hand, we aim to measure the redshift distribution, clustering and AGN content of the sub-mm population. Currently 40% complete, the survey is due to run until early 2006. Here I provide some early example results which demonstrate the potential power of our combined data set, and highlight a series of forthcoming papers which will present results based on the current interim sample of ~130 850-micron sources detected within the Lockman Hole and SXDF SHADES survey fields.

description: This study analyzed the effects that the use of crop insurance products and marketing alternatives had on the gross revenue per acre for an individual farm in Cass County. Crop insurance products and marketing strategies were analyzed individually to determine if they were effective in minimizing down side risk, and combined to determine if integration created synergies. A whole farm scenario analysis was run that included integrated strategies that implemented the same insurance coverage and marketing alternatives for each crop. Several general conclusions can be drawn for situations similar to the representative farm. When analyzed at the individual crop level, the use of crop insurance at the 65 percent level minimizes down side risk in wheat and corn, but not significantly in soybeans. Marketing alternatives generally increase the up side potential of gross revenue per acre, while doing little to minimize the down side risk. The integration of crop insurance products and marketing alternatives create a synergy at the lower levels of value at risk, where the down side risk is located. However, the use of integrated strategies does not increase the chances of achieving a cash flow breakeven gross revenue per acre over the base strategy, which did not include insurance or marketing alternatives. The breakeven level is not reached until the 70 percent level, which means that 7 out of 10 years, the farm will not cash flow. Output from the Bullock and AgRisk models are similar. This study may be used as a guide for producers and analysts in studying risk management strategies. To assist in the individual decision making process, further study will need to be done with yield data and budgets for the individual farm.

description: Abstract: Further to traditional corrosion monitoring techniques for rated deteriorations, nowadays modern electrochemical monitoring methods are promising for the control of non-rated damage mechanisms. Considering carbon steel as the most commonly used alloy in the oil and gas industry, there are special grades under NACE MR0175 standard which are immune to sour corrosion. However, according to the industry reports, their immunity can be terminated by upset conditions or on site repairs. This issue will impose either a high operational risk or exorbitant maintenance and inspection costs. Hence, in this paper, a new monitoring technology framework is discussed to lessen a catastrophic failure risk for carbon steel under wet H2S corrosion. In this regard, the application of a developed hybridized ZnO-graphene micro-electrode (ZnOG) with a mix band gap of 1.17 eV is studied. Under hydrogen sulfide attack and when ZnOG hybrids are excited by UV illumination, their photo-electrochemical responses are analyzed. ZnOG hybrids emanate informative impedance signals in a response to the formation of ZnO(1 – x)Sx nano-crystals.

description: We discuss the properties of layered Anderson/Kondo lattices with metallic electrons confined in 2D xy planes and local spins in insulating layers forming chains in z direction. Each spin in this model possesses its own 2D Kondo cloud, so that the Nozieres' exhaustion problem does not occur. The excitation spectrum of the model is gapless both in charge and spin sectors. The disordered phases and possible experimental realizations of the model are briefly discussed.

description: Business and community leaders frequently question the population level necessary to provide adequate sales volume for a particular type of business. This study examines population levels associated with specified numbers of 16 business types in North Dakota towns between 200 and 10,000 population in 2000. The data used to identify the presence of particular types of businesses in a given community were records of sales and use tax permit holders by Standard Industrial Classification (SIC) group from the North Dakota State Tax Department. Threshold populations for the 16 business types were estimated using ordinary least squares (OLS) regression analysis. The resulting estimates indicate that the populations required to support various business types vary substantially. Businesses with relatively low population requirements included eating and drinking places. Department stores and variety stores had the highest population thresholds among the businesses studied. When the threshold estimates were compared with similar estimates for 1988, the threshold population to support one business had decreased for four business types (eating places, drinking places, farm supply, and drug stores), while for the other 12, the threshold populations had increased.

description: Cooling methods and particle slowers as well as accelerators are basic tools for fundamental research and applications in different fields and systems. We put forward a generic mechanism to scale the momentum of a particle, regardless of its initial position and momentum, by means of a transient harmonic potential. The design of the time-dependent frequency makes use of a linear invariant and inverse techniques drawn from ''shortcuts to adiabaticity''. The timing of the process may be decided beforehand and its influence on the system evolution and final features is analyzed. We address quantum systems but the protocols found are also valid for classical particles. Similar processes are possible as well for position scaling.

description: Teaching efficiency is investigated for the nine departments in the College of Agriculture, Food Systems, and Natural Resources at North Dakota State University. Using Data Envelopment Analysis, departments are compared to their College peers in converting teaching faculty and teaching funds into three teaching outputs: student credit hours generated, undergraduate majors, and graduate students. Most departments are efficient in the technical conversion of inputs to outputs under variable returns to scale. Scale effects are evident, indicating some departments consistently extract higher average productivity from inputs in servicing undergraduate majors, graduate students, and in generating student credit hours.
From Big Bang to Asymptotic de Sitter: Complete Cosmologies in a Quantum Gravity Framework

description: Using the Einstein-Hilbert approximation of asymptotically safe quantum gravity we present a consistent renormalization group based framework for the inclusion of quantum gravitational effects into the cosmological field equations. Relating the renormalization group scale to cosmological time via a dynamical cutoff identification this framework applies to all stages of the cosmological evolution. The very early universe is found to contain a period of ``oscillatory inflation'' with an infinite sequence of time intervals during which the expansion alternates between acceleration and deceleration. For asymptotically late times we identify a mechanism which prevents the universe from leaving the domain of validity of the Einstein-Hilbert approximation and obtain a classical de Sitter era.

description: Wheat protein is one of the most important specifications used in domestic and import purchase contracts. It is used as a proxy for functional quality that is important in domestic markets and to importers. Large differences exist in functional characteristics amongst wheat that vary by protein level and class. The purpose of this paper is to analyze the demand for wheat protein across importing countries and through time. A choice based econometric model is specified and estimated using a pooled data set of wheat shipments. Results indicate that there have been shifts over time, purchase probabilities are highly price elastic and vary across importing regions. In addition, income, traded goods, urbanization, females in the work force, and domestic wheat production all impact purchase probabilities. Finally, wet gluten content and extraction rates have significant impacts on purchase probabilities.
The azimuthal anisotropy of electrons from heavy flavor decays in sqrt(s_NN) = 200 GeV Au-Au collisions by PHENIX

description: The transverse momentum dependence of the azimuthal anisotropy parameter v_{2}, the second harmonic of the azimuthal distribution, for electrons at mid-rapidity (|eta|<0.35) has been measured with the PHENIX detector in Au+Au collisions at sqrt(s_NN) = 200 GeV with respect to the reaction plane defined at high rapidities (|eta|=3-4). From the result we have calculated non-photonic electron v_{2}, which is expected to reflect the heavy-flavor azimuthal anisotropy, by subtracting v_{2} of electrons from other sources such as photon conversions, Dalitz decay etc.

description: As an important aspect of today’s efforts to reduce greenhouse gas emissions, the energy demand of passenger cars is a subject of research. Different drivetrain concepts like plug-in hybrid electric vehicles (PHEV) and battery electric vehicles (BEV) are introduced into the market in addition to conventional internal combustion engine vehicles (ICEV) to address this issue. However, the consumption highly depends on individual usage profiles and external operating conditions, especially when considering secondary energy demands like heating, ventilation and air conditioning (HVAC). The approach presented in this work aims to estimate vehicle consumptions based on real world driving profiles and weather data under consideration of secondary demands. For this purpose, a primary and a secondary consumption model are developed that interact with each other to estimate realistic vehicle consumptions for different drivetrain concepts. The models are parametrized by referring to state of the art contributions and the results are made plausible by comparison to literature. The sensitivities of the consumptions are then analysed as a function of trip distance and ambient temperature to assess the influence of the operating conditions on the consumption. The results show that especially in the case of the BEV and PHEV, the trip distance and the ambient temperature are a first-order influencing factor on the total vehicle energy demand. Thus, it is not sufficient to evaluate new vehicle concepts solely on one-dimensional driving cycles to assess their energy demand. Instead, the external conditions must be taken into account for a proper assessment of the vehicle’s real world consumption.

description: The presented study is aimed at analyzing the surface texture of amorphous hydrogenated carbon layers containing nickel nanoparticles (Ni-NPs@a-C:H) within their structure, which were deposited by Radio Frequency (RF) sputtering and RF-Plasma Enhanced Chemical Vapor Deposition (RF-PECVD) methods on glass substrates. Prepared films were then used as research material following their annealing at two different temperatures of 250 °C and 350 °C in an inert argon atmosphere. Series of height samples were taken with the help of atomic force microscopy (AFM) operating in a non-contact mode and examined in order to determine their fractal characteristics. Raw AFM data were first plane-fitted to remove the surface bow exhibiting the so-called residual surface, and then numerically processed to calculate the Areal Autocorrelation Function (AACF), which was later used to compute the Structure Function (SF). The log–log plots of the latter served for calculation of fractal properties of surfaces under investigation, including fractal dimension D, and pseudo-topothesy K. The analysis of 3-D surface texture helps to understand their essential characteristics and their implications as well as graphical models and their implementation in computer simulation.
