That particles are of less than 100nm in diameter called nano particles (NPS) and there are in the world naturally like volcanic activity. In the present investigation a new mixed halomercurate nano particle compound was synthesised and characterized. Triphenylphosphonium trichloromercorate (II) [P(C6H5)3H]+[HgCl3]- nanoparticle was synthesi -zed by using triphenylphosphonium chloride reaction ...
The vast majority of work in machine vision emphasizes the representation of perceived objects and events: it is these internal representations that incorporate thèknowledge' in knowledge-based vision or form thèmodels' in model-based vision. In this paper, we discuss simple machine vision systems developed by artiicial evolution rather than traditional engineering design techniques, and note t...
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
â âshodanâ is a multifunctional verb in persian language. this paper deals with six different functions of âshodanâ based on a purely formal approach. these functions are as follows: liking verb, light verb in some compound predicates, auxiliary verb, helping verb in passive voice, modal verb, and simple verb. the interface between lexicon and syntax, and the ways to show this relations...

a simple highly versatile and efficient sonochemical synthesis of 1,2,4,5-tetrasubstituted and 2,4,5-trisubstituted imidazoles is achieved by condensation of 1,2-dicarbonyl compound, aldehyde, ammonium acetate and primary amine using antimony trichloride immobilized on silica gel (sio2-osbcl2) as a catalyst in ethanol at moderate temperature. operational simplicity, practicability and applicabi...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
secondary flow investigation could be regarded as an important issue in open channel flow, in spite of its lower quantity compared to the base flow in the water course. it should be given special consideration because of the influence on some hydraulic factors in open channel, specifically in compound channels. in compound channels' due to the difference in the flow velocity of the main ch...
