This theoretical study reports on the impact of perceived indoor air quality for productivity loss in air-conditioned office buildings. A new derivation of productivity calculation model based on pollution loads and contaminant removal effectiveness is applied and the effect of the improved ventilation efficiency on productivity is estimated. The findings show that the proportion dissatisfied i...

We review the construction of regular p-brane solutions of M-theory and string theory with less than maximal supersymmetry whose transverse spaces have metrics with special holonomy, and where additional fluxes allow brane resolutions via transgression terms. We summarize the properties of resolved M2-branes and fractional D2-branes, whose transverse spaces are Ricci flat eight-dimensional and ...

Primary MgCl2.3.3EtOH adduct (PCT1) was prepared by melt quenching method and then submitted into a programmed thermal dealcoholation project using a fluidized bed reactor. During thermal dealcoholation program, different MgCl2.nEtOH support samples with n= 3.0, 2.7, 2.4, and 2.1 were selected and named as PCT2 to PCT5, respectively. Structural analysis of the support samples showed a significa...

the urban open space is the context in which the human activities and behavior takes place and the socio-cultural relations of people happen in it. public spaces are places responding to the daily needs and public life in cities. these spaces throughout time and based on the socio-cultural and economic conditions would transform. urban spaces also are places for various activities. in a simple ...

based on a gender equity perspective and within a pluralistic civil society, women should have equal rights for presence in and use of urban open spaces. despite this, various factors decrease their presence including inappropriate design of space, as well as socio-cultural obstacles. since women’s major place of presence and activity has traditionally been in or near home, neighborhood open sp...

Cities worldwide are urgently moving towards a more resilient and sustainable future. On this quest, national, regional, local governments apply combination of socio-spatial tools that regenerate transform the city’s leftover spaces. There is an abundance community gardens, cultural centers, large-scale urban developments that, through programmed activities, reactivate underused The bearers pro...
