in this study, bis(salicylaldehyde)-4-methyl-1,2-phenylenediimine (bsmp) as a schiff base ligand of n2o2-type and its mn and fe complex as m-bsmp catalyst were synthesized and characterized by uv-vis, ir spectroscopy and elemental analysis. the efficiency of fe- and mn-bsmp catalysts was evaluated in the oxidative decarboxylation of arylacetic acids with tetra-butylammonium periodate (n-bu4nio4...

introduction: the aim of this study was to evaluate the effect of bridge orientation in casting machine on castability and quality of base metal castings. methods: three groups of patterns with different direction and lengths in casting machine were casted and then studied qualitatively and quantitatively using mean and standard deviation in table of frequency. results: larger nodules and poros...

abstract background: invasive fungal infection is an opportunistic infection caused commonly by mucoraccae and aspergillus. it mostly occurs in patients with underlying disease. since it has a high mortality and morbidity rate, considering a treatment strategy seems necessary.   objective: since there has not been a clear protocol for treating these patients, we decided to establish a protocol ...

there are many occasions where the base of a robotic manipulator is attached to a moving platform, such as on a moving ship, terrain or space shuttle. in this paper a dynamic model of a robotic manipulator mounted on a moving base is derived using both newton-euler and lagrange-euler methods. the presented models are simulated for a mitsubishi pa10-6ce robotic manipulator characteristics mounte...

Acid-base interactions have found numerous applications in research dealing with adsorption of molecules of liquids on the surfaces of solids. The main focus of this research is to estimate the thermodynamic work of adhesion, determine mechanism of interactions, analyze the morphology of interfaces and various surface coatings, develop surface modifiers, study the aggregation of macromolecular ...

A base-monotone region with a base is a subset of the cells in a pixel grid such that if a cell is contained in the region then so are the ones on a shortest path from the cell to the base. The problem of decomposing a pixel grid into disjoint base-monotone regions was first studied in the context of image segmentation. It is known that for a given pixel grid and base-lines, one can compute in ...
