This paper investigates the function of windcatchers in dry regions in Middle East and compares them in different fields in two areas including Yazd-Iran, and Egypt. The study examines windcatchers in these areas in terms of cooling system and forms, with different plans, forms, constituent components and decorations.Reassessment of windcatchers in these areas can shed light on these difference...

the proposal of geomorphologic matters in relation to tourism is one of interdisciplinary research approaches that has been considered in recent years. in this manner, geomorphological sites are defined as geomorphological landforms and processes that have acquired a scenic/aesthetic, scientific, cultural/historical and/or a social/economic value due to human perception of geological, geomorpho...

We have used transmission electron microscopy (TEM) to observe the morphologies of ferrite nanoparticles synthesized using a radio frequency plasma torch. These nanoparticles were faceted, having cuboctahedral polygonal growth forms with exclusively the {111} and {100} type faces. A model for the critical nucleus shapes and the growth forms of small cuboctahedral particles is proposed consideri...

How do toddlers learn the names of geometric forms? Past work suggests that preschoolers have fragmentary knowledge and that defining properties are not understood until well into elementary school. The current study investigates when children first begin to understand shape names and how they apply those labels to unusual instances. We tested 25- and 30-month-old children's (N = 30 each) under...

Piroxicam has two different crystalline forms (known as needle and cubic forms), that they are different in physicochemical properties such as biological solubility. In the current research, using Taguchi experimental design approach the influences of five operating variables on formation of the piroxicam polymorph shapes in recrystallization were studied. The variables include type of solvent,...

The recent technological progress contributes to a huge increase of 3D models available in digital forms. Numerous applications were developed to deal with this amount of information, especially for 3D shape retrieval. One of the main issues is to break the semantic gap between shapes desired by users and shapes returned by retrieval methods. In this paper, we propose an algorithm to address th...

The Méma is a semi-arid region in central Mali with a rich archaeological heritage indicating the former existence of large urban settlements. The archaeological data suggest millennia of occupation history of the Méma preceding relatively sudden abandonment by the 14th or 15th century AD. Population numbers have remained low since then and today’s human presence in the area is sparse and large...

In-situ weathered bedrock, saprolite, is locally found in Scandinavia, where it is commonly thought to represent pre-Pleistocene weathering possibly associated with landscape formation. The age of weathering, however, remains loosely constrained, which has an impact on existing geological and landscape evolution models and morphotectonic correlations. Here we provide new geochronological eviden...

A variety of predictive models is currently used to map the spatial distribution of earth surface processes and landforms. In this study, we tested statistical consensus methods in order to improve the predictive accuracy of geomorphological models. The distributions of 12 geomorphological formations were recorded at a resolution of 25ha in a sub-arctic landscape in northern Finland. Nine envir...
