Evidence of Color Coherence Effects in W+jets Events from ppbar Collisions at sqrt(s) = 1.8 TeV

We report the results of a study of color coherence effects in ppbar collisions based on data collected by the D0 detector during the 1994-1995 run of the Fermilab Tevatron Collider, at a center of mass energy sqrt(s) = 1.8 TeV. Initial-to-final state color interference effects are studied by examining particle distribution patterns in events with a W boson and at least one jet. The data are compared to Monte Carlo simulations with different color coherence implementations and to an analytic modified-leading-logarithm perturbative calculation based on the local parton-hadron duality hypothesis.Comment: 13 pages, 6 figures.

A Search for Selectrons and Squarks at HERA

Data from electron-proton collisions at a center-of-mass energy of 300 GeV are used for a search for selectrons and squarks within the framework of the minimal supersymmetric model. The decays of selectrons and squarks into the lightest supersymmetric particle lead to final states with an electron and hadrons accompanied by large missing energy and transverse momentum. No signal is found and new bounds on the existence of these particles are derived. At 95% confidence level the excluded region extends to 65 GeV for selectron and squark masses, and to 40 GeV for the mass of the lightest supersymmetric particle.Comment: 13 pages, latex, 6 Figure

Fixed point theorems using control function in fuzzy metric spaces

The purpose of this paper is to obtain some results on existence of fixed points for contractive mappings in fuzzy metric spaces using control function. We prove our results on fuzzy metric spaces in the sense of George and Veeramani. Our results mainly generalize and extend the result of Grabeic (1988). As an application, a consequence theorem of integral type contraction is given in support of our result

Not AvailableResponse surface modeling approach was applied to optimize the ingredients level for barnyard millet based Nutri-Functional Snack (NFS) food using a D-optimal mixture design. The effect of ingredients level of barnyard millet (50–70%), quality protein maize (20–50%) and flax seed (0–20%) with constant level of skim milk powder (5%) on the physical and functional properties of NFS such as bulk density, colour, expansion ratio,water absorption index, water solubility index, crispiness and sensory were investigated. The regression models that explained the significant effects of different percentages of ingredients level on all the response variables were determined. The developed regression model of all the responses had a coefficient of determination (R2) and adjusted R2 value of higher than 0.9245 and 0.8490, respectively. The optimum conditions for maximum acceptability of NFS food having 70% barnyard millet, 28% quality protein maize and 2% flaxseed.Not Availabl
