Observing Long Colour Flux Tubes in SU(2) Lattice Gauge Theory

We present results of a high statistics study of the chromo field distribution between static quarks in SU(2) gauge theory on lattices of volumes 16^4, 32^4, and 48^3*64, with physical extent ranging from 1.3 fm up to 2.7 fm at beta=2.5, beta=2.635, and beta=2.74. We establish string formation over physical distances as large as 2 fm. The results are tested against Michael's sum rules. A detailed investigation of the transverse action and energy flux tube profiles is provided. As a by-product, we obtain the static lattice potential in unpreceded accuracy.Comment: 66 pages, 29 figures, uuencoded latex file with epsfigures (450 K), supplementary full colour figures are available via ftp, CERN-TH.7413/94 (extended version

Temporal, Situational and Interactional Features of Women’s Violent Conflicts

This article examines contextual and situational influences on the processural development of women\u27s violent conflicts. Through close analysis of 3 women\u27s accounts of their disputes and associated violent behaviours, we provide a rich description of how such events evolved over time and how the interviewees managed this process. Drawing upon both criminological and feminist theories, our analysis highlights existing gaps in the literature, providing an exploratory discussion of the interaction of gender with situational elements and the production of assaultive events

Matter degrees of freedom and string breaking in Abelian projected quenched SU(2) QCD

In the Abelian projection the Yang--Mills theory contains Abelian gauge fields (diagonal degrees of freedom) and the Abelian matter fields (off-diagonal degrees) described by a complicated action. The matter fields are essential for the breaking of the adjoint string. We obtain numerically the effective action of the Abelian gauge and the Abelian matter fields in quenched SU(2) QCD and show that the Abelian matter fields provide an essential contribution to the total action even in the infrared region. We also observe the breaking of an Abelian analog of the adjoint string using Abelian operators. We show that the adjoint string tension is dominated by the Abelian and the monopole contributions similarly to the case of the fundamental particles. We conclude that the adjoint string breaking can successfully be described in the Abelian projection formalism.Comment: 16 pages, 10 figures, 2 table

Effect of Fungicidal Seed Treatments on Common Root Rot of Spring Wheat and Barley

Common root rot of hard red spring wheat, durum and barley concurs throughout the Spring regions of the Great Plains in the USA and Canada. Cochliobiolus Sativas is fungus that primarily produces root rot. Crop losses were determined to be 10% in barley and 5% in spring wheat with losses up to 30% in some fields in some years. Crop rotation and plantings of resistant cultivars up to this point were the major disease management tools. Farmers found growing non-cereal crops to be unprofitable. Also, due to many agronomic and quality factors, many farmers continued to plant susceptible crops.Protectant fungicide formulations have ben long applied to cereal seed to prevent seed decay, damping-off and seedling blight and some seed-bore diseases such as 'smuts'. Cochliobolus Salivas may cause a seed-borne infection known as 'black point'. Older treatments hadn't been successful in reducing the soil-borne phase of common root rot in adult crops. When controlled, crop yields did not increase. This article discusses a systematic treatment of fungicides on root rot control' of spring wheat and barley in North Dakota. The Triadimenol and Difenconazole treatments produced the most promising returns on reducing CRR and increasing crop yields
