The dynamical stability and evolution of disc galaxies with different disc thickness as well as various fraction and concentration of stellar counter-rotation is investigated with self-consistent numerical simulations. In particular, systems of nested, counter-rotating, stable bars are presented. As for the direct case, the nuclear secondary bar rotates faster than the primary bar. Contrary to ...

The optimal track allocation problem (OPTRA), also known as the train routing problem or the train timetabling problem, is to find, in a given railway network, a conflict-free set of train routes of maximum value. We propose a novel integer programming formulation for this problem that is based on additional ‘configuration’ variables. Its LP-relaxation can be solved in polynomial time. These re...

In Korea, smoke-free regulations have been gradually implemented in bars based on venue size. Smoking bans were implemented in 2013 for bars ≥150 m², in 2014 for bars ≥100 m², and in 2015 for bars of all sizes. The purpose of this study was to determine indoor fine particle (PM2.5) concentrations in bars before and after implementation of the smoke-free policies based on venue size. Indoor PM2....

This study investigated whether a stacked bar’s vertical arrangement or single-object properties underlie its accuracy for proportion judgments. We hypothesized that observers would be less accurate when stacked bars were separated than when they formed a single object, according to the object-based theory of attention (Duncan, 1984). Thirty participants judged proportions with three different ...

The utilization of unbounded external reinforcing bars is one of the strengthening methods used after loading stage and before failure. The method has been used in different forms to strengthen members of reinforced concrete structures. To investigate the effect of utilization of post-tensioned reinforcing bars in this method of strengthening, a number of reinforced concrete beams was tested. S...

OBJECTIVE To test whether standard information for patients using Crunchie and Aero chocolate bars to explain bone health and risk of fracture is robust. DESIGN Observational study. SETTING Domestic kitchen in rural west Wales. PARTICIPANTS 10 Crunchie bars and 10 Aero bars. MAIN OUTCOME MEASURE Fracture after falls from varying heights. RESULTS Both Crunchie and Aero bars exhibited t...

snacks play a major role to supply nutritional needs of the armed forces in different operating conditions, because they are considered as a replacement for carbohydrate reserves in muscles after physical activity. the purpose of this study was to formulate and test long-lasting energizing snacks for military on different operations. 6 cereal bars were prepared containing formulations sesame se...
