Over the past several years many issues have come to light that have highlighted the need for improved ventilation in multi unit residential buildings (MURB's). High-rise buildings, for example, are all too often connected with poor indoor air quality. When looking at this issue from the perspective of urbanism and the trend to increasing the density of our urban centres, there is a dramatic ne...

In this letter, it is shown that dark energy is contributed by riccion (a particle concept for physical aspect of the Ricci scalar curvature) in a natural way without any input in the theory for it. In contrast to other models, where an idea for dark energy is introduced in the beginning of the theory, here it emerges from the gravitational sector spontaneously. Interestingly, it is found that ...

Aerodynamic testing of low-rise structures is fraught with difficulties that can be the cause of large measurement errors, resulting in the underestimation of aerodynamic pressures by a factor of as much as two. The errors are primarily attributable to the inadequate knowledge and simulation of wind flows affecting low-rise buildings, especially residential homes in suburban environments. A typ...

The complexation of an arene to a chromium tricarbonyl unit changes its chemical behavior, giving rise to unprecedented transformations. The electron-withdrawing effect of the unit allows efficient nucleophilic attack (S(N)Ar and dearomatization reactions), stabilizes negative charges in benzylic positions and activates C(Ar)-halogen bonds for cross-coupling reactions. In addition, the Cr(CO)(3...

Living in a residential high-rise is now becoming a lifestyle trend among the urban professional community in Malaysia. As opposed to a landed property, in a residential high-rise, residents must set up a Management Corporation (MC) to regulate and manage all the amenities provided by the developer, as stipulated in the Strata Title Act of 1985. To a certain extent, the idea seems to work succe...
