growing tendency for urbanization and rapid development of the cities has resulted in urban neighborhoods obstructing the access of each other to the natural sources e.g. solar energy, natural ventilation. sunlight as the main part of input energy in urban energy balance equation and natural lighting is of vital importance. this paper attempts to achieve an optimum morphology for residential bl...

despite the close relationship between collective memory and urban structure, as the relationship between what is hidden and what is visible, rapid changes throughout the city have caused a disconnection between integrated memories and landscape cohesion. as a context for memories, the historical urban landscape proves valuable. the present research seeks to identify elements and signs in urban...

India is highly vulnerable to natural disasters and climate extremes, which have significant consequences to the urban population. In fact, natural disasters are triggered by natural hazards, but its impact on a certain population depends mostly on human factors. In India what makes the urban population more vulnerable are the high population density; [...] the poor living conditions; and the u...

We investigated how such homogenization influences ant communities. We monitored ant species richness and abundance in natural, semi-natural, urban, and agricultural habitats for one year, along an u...

alkaline waste spoils [4]). Some argue that the increase in hard surfaces in cities represents a replication of many of the key features of natural habitat templates [7] found in unproductive rocky areas [5,8,9]. Urban habitats probably provide a continuum of selective novelty, from remnant natural habitats or anthropogenic analogs of other habitats to wholly novel environments. Such research c...

intra-city natural structures have always had a key role in creating sustainable urban greenspaces. adapting to natural features and relating the intra-city greenspaces to such natural structures as river-valleys, hillsides, lakes and forests, guarantee the endurance, sustainability and longevity of the natural quality of city. this paper looks at intra-city natural structures which have underg...

Vitamin A status in a sample of pregnant and lactating women living in several representative regions of Congo was assessed and compared between August and September 2004. This survey was conducted using a randomized two-stage cluster-sampling method with stratification on 90 clusters, each consisting of at least 15 women. Vitamin A status was determined in a total of 1,054 individuals, using t...

BACKGROUND Raising awareness of women on danger signs of pregnancy, childbirth and the postpartum period is crucial for safe motherhood. In Ethiopia, a country where maternal morbidity and mortality is high little is known about knowledge level of pregnant women on obstetric danger signs. The objective of this study was to assess pregnant women's knowledge about obstetric danger signs in Aleta ...
