    Methods of applying ammonium phosphate fertilizer in a continuous wheat rotation in southwest Saskatchewan

    Get PDF
    Non-Peer ReviewedA field experiment was conducted in the Brown Soil Zone comparing three methods of fertilizer placement: deep banding, side banding, and with the seed, using ammonium phosphate fertilizer in a zero-till continuous wheat rotation. Placement with the seed was found to produce the highest yield and had the lowest cost of production

    Thickness-dependent thermal properties of amorphous insulating thin films measured by photoreflectance microscopy

    In this work, we report on the measurement of the thermal conductivity of thin insulating films of SiO2 obtained by thermal oxidation, and Al2O3 grown by atomic layer deposition (ALD), both on Si wafers. We used photoreflectance microscopy to determine the thermal properties of the films as a function of thickness in the 2 nm to 1000 nm range. The effective thermal conductivity of the Al2O3 layer is shown to decrease with thickness down to 70% for the thinnest layers. The data were analyzed upon considering that the change in the effective thermal conductivity corresponds to an intrinsic thermal conductivity associated to an additional interfacial thermal resistance. The intrinsic conductivity and interfacial thermal resistance of SiO2 were found to be equal to 0.95 W/m·K and 5.1 × 10− 9 m2K/W respectively; those of Al2O3 were found to be 1.56 W/m·K and 4.3 × 10− 9 m2K/W

    Measurements of Protein-Protein Interactions by Size Exclusion Chromatography

    A method is presented for determining second virial coefficients B_2 of protein solutions from retention time measurements in size exclusion chromatography (SEC). We determine B_2 by analyzing the concentration dependance of the chromatographic partition coefficient. We show the ability of this method to track the evolution of B_2 from positive to negative values in lysozyme and bovine serum albumin solutions. Our SEC results agree quantitatively with data obtained by light scattering.Comment: 18 pages including 1 table and 5 figure

    Zero-minimum tillage seeding and fertilizer placement techniques for zero-tillage

    Non-Peer ReviewedPreliminary results from the field evaluation of zero and minimum tillage seeding machines, as well as fertilizer placement techniques for zero-tillage are presented. Narrow hoe opener (Noble 2000), conventional double-disc (Haybuster 1206), as well as two modified double-disc press drills have been compared for their seeding performance and effects on crop yields in a continuous zero-till wheat test. Further, an air-seeder, a discer and a conventional hoe press-drill have been field evaluated both on cultivated fallow and stubble situations. Deep banding and side banding (approximately 2.5 cm from seed) of fertilizer using both disc and hoe press-drills have been compared to seed-placed fertilizer application

    Optimal classical-communication-assisted local model of n-qubit Greenberger-Horne-Zeilinger correlations

    We present a model, motivated by the criterion of reality put forward by Einstein, Podolsky, and Rosen and supplemented by classical communication, which correctly reproduces the quantum-mechanical predictions for measurements of all products of Pauli operators on an n-qubit GHZ state (or ``cat state''). The n-2 bits employed by our model are shown to be optimal for the allowed set of measurements, demonstrating that the required communication overhead scales linearly with n. We formulate a connection between the generation of the local values utilized by our model and the stabilizer formalism, which leads us to conjecture that a generalization of this method will shed light on the content of the Gottesman-Knill theorem.Comment: New version - expanded and revised to address referee comment
