The captive environment can lack opportunities for the expression of a range of natural behaviours (Wemelsfelder, 1997) and can contribute to the establishment of stereotypic or undesirable behaviours. Appropriately enriched environments have been shown to have positive effect on both physiological (Newberry, 1995) and psychological (Roy et al, 2001) welfare and to enhance the range of behaviou...

Abslruct-This paper reports on the initial experimental evaluation of the Reusability-Oriented Parallel programming Environment (ROPE 1, a software component reuse system developed at the University of Texas at Austin. ROPE helps the designer find and understand compo vents by using a new classification method called structured relational classification. ROPE is a part of a development environm...

The importance of renewable energy sources for the electrical power supply has grown rapidly in the past decades. Their often unpredictable nature however poses a threat to the stability of the existing electric grid. Hydroelectric powerplants play an important role in regulating the integration of renewable energy sources into the network by supplying on-demand load balancing as well as primar...

Calf housing often only meets the basic needs of calves, but there is a growing interest in providing enrichments. This study described the behaviour of calves when they were given the opportunity to interact with two commonly available enrichment items. Female and male calves (approximately 11 days old) were pair-housed in 8 identical pens fitted with an automated brush and a hanging rope. Fre...

A 24 year old otherwise healthy male was presented with a chief complaint of giving way in the left knee. MRI reportedcomplete anterior cruciate ligament (ACL) tearing. Arthroscopy showed ACL agenesis, ring-shaped lateral meniscus,and an anomalous thick band extending from the anterior horn of the lateral meniscus to the intercondylar notch of thelateral femoral condyle, which...

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...

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....

Time-dependent resistive magnetohydrodynamic simulations are carried out to study a flux rope eruption caused by magnetic reconnection with implication in coexistent flare-CME (coronal mass ejection) events. An early result obtained in a recent analysis of double catastrophe of a flux rope system is used as the initial condition, in which an isolated flux rope coexists with two current sheets: ...

In this paper we construct a natural geometric structure for the space of shapes of a star-shaped polygon. Roughly speaking we find: The set of similarity classes of marked stars forms a hyperbolic right angle pentagon bundle over the space of external angle sets of inscribed pentagons. The assignment of the shape of its fiber to each angle set forms a hyperbolic plane bundle over the Teichmiil...
