Most Relevant Explanation (MRE) is a method for nding multivariate explanations for given evidence in Bayesian networks [12]. This paper studies the theoretical properties of MRE and develops an algorithm for nding multiple top MRE solutions. Our study shows that MRE relies on an implicit soft relevance measure in automatically identifying the most relevant target variables and pruning less rel...

The amount of petroleum hydrocarbon and heavy metals in the sediment of the Persian Gulf’s shore, at 8 selected stations were determined and showed the maximum of 143.6 and 58.6 mg/kg sediment, respectively, both maximum amounts were related to Emam Hassan zone which is located at 50 kilometers to west Boushehr port. Bioremediation of contaminated sediment were studied in slurry and solid-state...

background: the traditional cyclone has been developed for the removal of airborne silica particles from local exhaust ventilation (lev). the objective of this research was to evaluate the effects of velocity and particles load on efficiency of cyclone in the stone crushing units at azendarian area. methods: after the designing and installing the traditional cyclone, downstream and upstream sam...

PURPOSE To determine the correlation in abdominal aortic stiffness obtained using magnetic resonance elastography (MRE) (μ(MRE)) and MRI-based pulse wave velocity (PWV) shear stiffness (μ(PWV)) estimates in normal volunteers of varying age, and also to determine the correlation between μ(MRE) and μ(PWV). MATERIALS AND METHODS In vivo aortic MRE and MRI were performed on 21 healthy volunteers ...

PURPOSE To demonstrate the feasibility of 1D MR elastography (MRE) to rapidly assess skeletal muscle stiffness in vivo. MATERIALS AND METHODS Shear waves were induced in the vastus medialis muscle (VM) using a pneumatic driver at 90 Hz and 2D MRE data were collected. Spatially selective excitations were used to produce 1D projections of MRE data oriented along the direction of propagating wav...

Magnetic resonance enterography (MRE) is fast becoming the first-line radiological investigation to evaluate the small bowel in patients with Crohn's disease. It can demonstrate both mural and extramural complications. The lack of ionizing radiation, together with high-contrast resolution, multiplanar capability and cine-imaging make it an attractive imaging modality in such patients who need p...

co-precipitation procedure was applied in order to obtain different kinds of magnetic nanoadsobents for the removal of pb(ii) and cu(ii) toxic metal ions from wastewater samples. prepared nanoadsorbents were characterized by fourier transform infrared spectroscopy (ft-ir), x-ray diffractometer (xrd), scanning electron microscopy (sem) and thermogravimetric analysis (tga). the average sizes of t...

background: heavy metals have been recognized as harmful environmental pollutant known to produce highly toxic effects on different organs and systems of both humans and animals. the aim of this paper is to evaluate the adsorption potential of chitosan for the removal of pb(ii), fe(ii) and cu(ii) ions from aqueous solutions. methods: this study was conducted in laboratory scale. in this paper c...
