Comfort, W.W. and J. van Mill, Some topological groups with, and some without, proper dense subgroups, Topology and its Applications 41 (1991) 3-15. Continuing earlier investigations into the question cf the existence of a proper dense subgroup of a given topological group, the authors obtain some positive and some negative results, as follows: (a) Every non-degenerate connected Abelian group c...
متن کاملThe rope
We are aware that all information published by each issue of this journal needs the squeeze and sweat of thousands of people. On one end of the rope, researchers and higher education institutions work hard to produce science to the highest degree of excellence. On the other end, reviewers silently filter manuscripts, thus improving the quality and accuracy of information that has been approved....
متن کاملUnstable Surface Improves Quadriceps:Hamstring Co-contraction for Anterior Cruciate Ligament Injury Prevention Strategies
BACKGROUND Increasing quadriceps:hamstring muscular co-contraction at the knee may reduce the risk of anterior cruciate ligament (ACL) injury. The purpose of this investigation was to examine muscle activation in the quadriceps and hamstrings and peak kinematics of the knee, hip, and trunk when performing a single-leg drop (SLD) on to a Bosu ball (unstable surface) compared with on to the floor...
متن کاملModeling Rope Reliability
In this paper we attempt to model the reliability of a steel rope that is susceptible to breakage during its operation. Each individual strand of the rope is modeled using a counting process for breakages and the associated process describing new breakages. The decision to replace the rope is based on the maximum number of breakages in the strands along a given length. Using a stochastic simula...
