During recent years, landslide incidence has been increased in different areas with different reasons like change in land use and road introduction. It is necessary to research and survey that’s creation factors and identity sensitive areas to prohibit of probable damages. For this reason, This study were carried out in Northern of Tehran watershed with about 42.14 km2 area. In order to landsli...
Based on the existing study of online comment on the short text paradigm and the golden section method as introduced, an improved method that calculates the short text distance based on the Golden section method is hereby proposed. The new method considers the text distance as the combination between the semantic distance and the form distance on the basis of the importance weight and the prefe...
introduction: ordered subset expectation maximization (osem), is an effective iterative method for spect image reconstruction. the aim of this study is the evaluation of the role of system matrix in osem image reconstruction method using four different physical beam radiation models with three detection configurations. methods: spect was done with an arc of 180 degree in 32 projections after i...
the aim of this study preparation of the predicted soil maps by using kriging and inverse distance weighting methods in east rangeland of semnan. sampling was done within each unit of sampling parallel transects and 1 vertical transect with 750m length. soil samples were taken from 0-20 cm in starting and ending points of each transect. there were used kriging and inverse distance weighting met...
Solid waste is an integral part of human life, generation of various quantities and qualities of which is one of the greatest environmental problems of the current era. Application of modern tools and technology to find the right place for recycling, where the volume of recyclable materials can be reduced, seems vital for reusing the recoverable materials contained in normal waste and their rec...
in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...
abstract objectives gradual increase length and complexity of utterance (gilcu) therapy method is a form of operant conditioning. this type of treatment is very precise and controlled that is done in 54 steps in 3 speech situations consisted of monologue, reading and conversation. this study aimed to examine the effects of gilcu treatment method on reduction of speech dysfluency of school-age...
phototherapy is a conventional method of lowering serum bilirubin in newborn jaundice. we evaluated the short distance in relation to conventional long distance phototherapy between the light-source and the skin surface. healthy jaundiced neonates undergoing phototherapy were randomized into two groups. the distance between the light-source and the newborn's skin was 20 and 40 centimeters (g20;...
background and objectives: in continuous medical learning programs, selection of appropriate learning methods is important for streaming individuals by learning process. the goal of this study is to compare in-presence learning method with distance learning method and explore their effect on the knowledge of health workers (practical nurses) in terms of reduced expenses. methods: the study is...
