Large areas of Iran are under the influence of wind erosion thus it is important that we recognize three zones ofremoval, transportation and deposition. The deposition zone is very important due to more damages and tangibleeffects. In this study we try to obtain a comprehensive idea to Persian desert with use of laboratory facilities, remotesensing, GIS and field surveying. We survey 28 ergs in...

Beyond critique of current maturity models, the research literature has neglected to supply empirical evidence of the value Knowledge Management (KM) holds for organizations. Specifically, not much is known regarding KM in developing economies. The majority of studies, in common with other emergent business philosophies, are for the most part focused on large organizations of developed economie...

This study was conducted for palynological investigation of recent deposits from east Isfahan in order to reconstruct past environmental conditions of this region. Segzi area is located in 30 km east Isfahan and Rangideh area is 65 km in south east Isfahan. In these areas it was seen, in depth of soil profile, dark layers containing organic matters. Soil samples were taken from five points and ...

Futures studies is a value knowledge and has a two-way communication with the worldview, ideology and culture of nations. Humanities is one of the factors that influence the field of futures studies. Hence the human sciences itself could be the subject of future studies. In this study, we have tried to discuss the role of future studies in knowledge management in the field of humanities. Theref...

The development of the south polar Chasma Australe re-entrant has been discussed for several years and a variety of theories including eolian, aquatic, subglacial and tectonic mechanisms have been proposed for its formation. Morphological observations and studies of recent imagery support the idea of successive headward erosion and removal of volatile–rich sub–surface material combined with col...

Background: Recent studies have shown an increasing incidence of antibiotic resistance in dacryocystitis. Management diseases may include determining microbial agents and choosing appropriate antibiotics for treatment. Objectives: This study aimed to present the best treatments To this end, specimens' microbiology susceptibility were examined patients with dacryocystitis laboratory Kashan Unive...

BACKGROUND The Australian redclaw crayfish (Cherax quadricarinatus, von Martens), is native to Australasia, but has been widely translocated around the world due to aquaculture and aquarium trade. Mostly as a result of escape from aquaculture facilities, this species has established extralimital populations in Australia and alien populations in Europe, Asia, Central America and Africa. In South...

Up to date, three gravity models for the Andean section at 32° south latitude have been published. Two of them did not have seismic reflection/refraction data to constrain the subsurface geometry. The other one included seismic data to fit thicknesses and determined density contrasts using velocity-density curves. Furthermore, all previous models assumed a homogeneous mantle. In this paper a ne...
