Forage Plants at the Highmore Sub-Station, 1906

The season of 1906 at the Highmore Experiment Station was one of considerable rainfall. The precipitation for the year amounted to about twenty-five inches which is but a trifle under that of 1905. This precipitation, however, was not the greatest in the same months of the year as that in 1905. In 1906 considerable rain fell during the months of May and August, with but very little during the months of June and July. In 1905 the fall was very uniform and heavy during the months of May, June and July. Both seasons were favorable to the production of large crops of both corn and forage. The scant rainfall during the month of July and early part of August in 1906 was very noticeable in its effect upon crops and probably materially lessened the yield of some kinds. The rain on the 9th of August came just in time to save many of the crops which would otherwise have suffered. (See table 1.) The work of the Highmore Experiment Station, in all lines, is very encouraging. It may be that this condition is due to the excessive rainfall of the last two years, but it appears to the writer that this is not wholly the case. The work seems to be so well in hand that it is doubtful if any dry spell such as has been experienced in years past can materially check: the progress of the work. Plant-breeding work is being extended so as to cover many of the crops which seem to show adaptability to the region. Alfalfa, millet, sorghum and corn are receiving their due share of attention, and some work is also being done with annual leguminous plants and grasses. The work with all of the crops has been very satisfactory

Forage Plants and Cereals at the Highmore Sub-Station for 1904-5

The State Agricultural Experiment Station at Highmore, Hyde County, South Dakota, has been in operation for seven years of the location in testing and developing drouth [sic] resistant crops. Hyde County is fairly representative of a large portion of the state from the James River west, which is not well represented by the Brookings Station. The primary purpose of the Highmore Station was to test and develop grasses and forage crops, as it was supposed that this region would be largely a grass country instead of a farming country. Later developments have shown it desirable and in fact necessary to enlarge somewhat upon the work as it was first planned. Co-operative work with the United States Department of Agriculture in the testing of varieties of cereals has been carried on for three years. The report of this work as given by Mr. John S. Cole forms the latter part of this bulletin. The experimental farm at Highmore consists of 117 acres of land. The character of the soil and the lay of the land is somewhat poorer than the average in Hyde County. This, however, is not a disadvantage, for on this account no one can consider the records from the Highmore Station as coming from an unusually good piece of land and, therefore, unreliable for general comparisons

Report of Investigations at The Highmore Station for 1903

The work of testing grasses and other forage plants at Highmore during the season of 1903 was carried on by Mr. Sylvester Balz under the direction of Professor De Alton Saunders. The following report of the work has been prepared from the data furnished by Mr. Balz at the close of the season\u27s work. Professor Saunders severed his connection with the South Dakota Agricultural College in October, 1903. There being more land at the station than necessary to carry on the tests of forage plants, a part of it was used by Professor Chilcott and if Mr.Cole in testing macaroni wheats and other grains in co-operation with the United States Department of Agriculture. Their report forms the latter part of this bulletin

Preliminary Experiments with Vapor Treatments for Prevention of Stinking Smut of Wheat

The stinking smut of wheat is a disease so common as to be very familiar to the farmers of South Dakota. Its presence can be easily detected by the characteristic smutted kernels in the threshed grain and by the disagreeable odor. So much has been written upon the details of the growth of the parasite which causes the disease that the facts with not be taken up or discussed in this bulletin. . . . In view of these facts the writer in the winter of 1903-04 began a series of experiments to secure a treatment for smut which would not necessitate the wetting of the seed grain. The experiments were begun before any search of the literature upon the subject was made to determine whether similar experiments had been conducted previous to this time. Later upon investigati.ng the literature it was found that various botanists had conducted experiments with this object in view but in no case had these progressed beyond the first stages of experimentation. Some of the experiments recorded here are therefore to a certain extent a repetition of the experiments of others. It was also discovered that a powder commercially known as “Ozonet gas powder had been offered for sale to be mixed with seed grain for the prevention of smut

Ab initio Quantum and ab initio Molecular Dynamics of the Dissociative Adsorption of Hydrogen on Pd(100)

The dissociative adsorption of hydrogen on Pd(100) has been studied by ab initio quantum dynamics and ab initio molecular dynamics calculations. Treating all hydrogen degrees of freedom as dynamical coordinates implies a high dimensionality and requires statistical averages over thousands of trajectories. An efficient and accurate treatment of such extensive statistics is achieved in two steps: In a first step we evaluate the ab initio potential energy surface (PES) and determine an analytical representation. Then, in an independent second step dynamical calculations are performed on the analytical representation of the PES. Thus the dissociation dynamics is investigated without any crucial assumption except for the Born-Oppenheimer approximation which is anyhow employed when density-functional theory calculations are performed. The ab initio molecular dynamics is compared to detailed quantum dynamical calculations on exactly the same ab initio PES. The occurence of quantum oscillations in the sticking probability as a function of kinetic energy is addressed. They turn out to be very sensitive to the symmetry of the initial conditions. At low kinetic energies sticking is dominated by the steering effect which is illustrated using classical trajectories. The steering effects depends on the kinetic energy, but not on the mass of the molecules. Zero-point effects lead to strong differences between quantum and classical calculations of the sticking probability. The dependence of the sticking probability on the angle of incidence is analysed; it is found to be in good agreement with experimental data. The results show that the determination of the potential energy surface combined with high-dimensional dynamical calculations, in which all relevant degrees of freedon are taken into account, leads to a detailed understanding of the dissociation dynamics of hydrogen at a transition metal surface.Comment: 15 pages, 9 figures, subm. to Phys.

Patient-reported treatment toxicity and adverse events in Black and White women receiving chemotherapy for early breast cancer

Purpose: It is not known whether chemotherapy-related symptom experiences differ between Black and White women with early breast cancer (Stage I–III) receiving current chemotherapy regimens and, in turn, influences dose delay, dose reduction, early treatment discontinuation, or hospitalization. Methods: Patients self-reported their race and provided symptom reports for 17 major side effects throughout chemotherapy. Toxicity and adverse events were analyzed separately for anthracycline and non-anthracycline regimens. Fisher’s exact tests and two-sample t-tests compared baseline patient characteristics. Modified Poisson regression estimated relative risks of moderate, severe, or very severe (MSVS) symptom severity, and chemotherapy-related adverse events.Please check and confirm that the authors and their respective affiliations have been correctly identified and amend if necessary.no changes Results: In 294 patients accrued between 2014 and 2020, mean age was 58 (SD13) and 23% were Black. For anthracycline-based regimens, the only significant difference in MSVS symptoms was in lymphedema (41% Black vs 20% White, p =.04) after controlling for axillary surgery. For non-anthracycline regimens, the only significant difference was MSVS peripheral neuropathy (41% Blacks vs. 23% White) after controlling for taxane type (p =.05) and diabetes (p =.05). For all other symptoms, severity scores were similar. Dose reduction differed significantly for non-anthracycline regimens (49% Black vs. 25% White, p =.01), but not for anthracycline regimens or in dose delay, early treatment discontinuation, or hospitalization for either regimen. Conclusion: Except for lymphedema and peripheral neuropathy, Black and White patients reported similar symptom severity during adjuvant chemotherapy. Dose reductions in Black patients were more common for non-anthracycline regimens. In this sample, there were minimal differences in patient-reported symptoms and other adverse outcomes in Black versus White patients

Search for displaced vertices arising from decays of new heavy particles in 7 TeV pp collisions at ATLAS

We present the results of a search for new, heavy particles that decay at a significant distance from their production point into a final state containing charged hadrons in association with a high-momentum muon. The search is conducted in a pp-collision data sample with a center-of-mass energy of 7 TeV and an integrated luminosity of 33 pb^-1 collected in 2010 by the ATLAS detector operating at the Large Hadron Collider. Production of such particles is expected in various scenarios of physics beyond the standard model. We observe no signal and place limits on the production cross-section of supersymmetric particles in an R-parity-violating scenario as a function of the neutralino lifetime. Limits are presented for different squark and neutralino masses, enabling extension of the limits to a variety of other models.Comment: 8 pages plus author list (20 pages total), 8 figures, 1 table, final version to appear in Physics Letters

Measurement of the polarisation of W bosons produced with large transverse momentum in pp collisions at sqrt(s) = 7 TeV with the ATLAS experiment

This paper describes an analysis of the angular distribution of W->enu and W->munu decays, using data from pp collisions at sqrt(s) = 7 TeV recorded with the ATLAS detector at the LHC in 2010, corresponding to an integrated luminosity of about 35 pb^-1. Using the decay lepton transverse momentum and the missing transverse energy, the W decay angular distribution projected onto the transverse plane is obtained and analysed in terms of helicity fractions f0, fL and fR over two ranges of W transverse momentum (ptw): 35 < ptw < 50 GeV and ptw > 50 GeV. Good agreement is found with theoretical predictions. For ptw > 50 GeV, the values of f0 and fL-fR, averaged over charge and lepton flavour, are measured to be : f0 = 0.127 +/- 0.030 +/- 0.108 and fL-fR = 0.252 +/- 0.017 +/- 0.030, where the first uncertainties are statistical, and the second include all systematic effects.Comment: 19 pages plus author list (34 pages total), 9 figures, 11 tables, revised author list, matches European Journal of Physics C versio

Observation of a new chi_b state in radiative transitions to Upsilon(1S) and Upsilon(2S) at ATLAS

The chi_b(nP) quarkonium states are produced in proton-proton collisions at the Large Hadron Collider (LHC) at sqrt(s) = 7 TeV and recorded by the ATLAS detector. Using a data sample corresponding to an integrated luminosity of 4.4 fb^-1, these states are reconstructed through their radiative decays to Upsilon(1S,2S) with Upsilon->mu+mu-. In addition to the mass peaks corresponding to the decay modes chi_b(1P,2P)->Upsilon(1S)gamma, a new structure centered at a mass of 10.530+/-0.005 (stat.)+/-0.009 (syst.) GeV is also observed, in both the Upsilon(1S)gamma and Upsilon(2S)gamma decay modes. This is interpreted as the chi_b(3P) system.Comment: 5 pages plus author list (18 pages total), 2 figures, 1 table, corrected author list, matches final version in Physical Review Letter

Measurement of the inclusive isolated prompt photon cross-section in pp collisions at sqrt(s)= 7 TeV using 35 pb-1 of ATLAS data

A measurement of the differential cross-section for the inclusive production of isolated prompt photons in pp collisions at a center-of-mass energy sqrt(s) = 7 TeV is presented. The measurement covers the pseudorapidity ranges |eta|<1.37 and 1.52<=|eta|<2.37 in the transverse energy range 45<=E_T<400GeV. The results are based on an integrated luminosity of 35 pb-1, collected with the ATLAS detector at the LHC. The yields of the signal photons are measured using a data-driven technique, based on the observed distribution of the hadronic energy in a narrow cone around the photon candidate and the photon selection criteria. The results are compared with next-to-leading order perturbative QCD calculations and found to be in good agreement over four orders of magnitude in cross-section.Comment: 7 pages plus author list (18 pages total), 2 figures, 4 tables, final version published in Physics Letters
