in this research performed during 1993-1994, the effluent of behran oil refmery, in south of tehran, which produces different types of industrial oil and greases, was studied and 3 methods of gravity separation, coagulation and flocculation and dissolved air flotation were investigated. in the first phase of the survey, the quality and quantity of the effluent were determined. this showed an av...

Abstract Liposomes are used widely as drug delivery systems in different forms including nanosuspensions, osmotic pumps, infusion pumps and IV injections. Some of these systems (e.g. infusion or osmotic pumps) might stay stagnant for a long time during or before administration, and therefore, might face phase separation. In spite of these, there is no data available about the behavior of lipos...

The response of Baban Tsauni (Nigeria) lead-gold ore to gravity separation methods was investigated in this research work. Value addition to run-off mines is always necessary in order to reduce downstream metal extraction costs. Gravity separation methods (the focus of this work) are the cheapest beneficiation methods. This study applied three gravity separation methods: jigging, multi-gravity ...

the results of batch settling tests (bst) are used to investigate settling behavior of solids suspension, which contribute to sizing thickeners. conventional methods in analyzing bst on the basis of visual and graphical procedures lead to sub-optimally sized and selected thickeners. a computational approach based on quantitative analysis of bst can be beneficial. about 300 settling experiments ...

Detection of subsurface structures by means of gravity method can be used to determine mass distribution and density contrast of rock units. This distribution could be detected by different geophysical methods, especially gravity method. However, gravity techniques have some drawbacks and can't be always successful in distinguishing subsurface structures. Performance of the gravity technique co...

this paper attempts to investigate the capability of the numerical finite element method for the removal of the regional effects from the observed gravity data from the dehnow anticline. from a geological point of view, the dehnow area is a part of the fars sedimentary basin south-east iran. the khamy formation and bangestan group are the oldest geological structures in the area that have outcr...
