the present study examined the role of mood state on self – appraisal of problem solving ability. the subjects were 115 female students (ages 13 to 14) who were randomly assigned to three groups (two experimental and one control groups). in order to induce mood states, three films (happy and sad films for the two experimental groups and documentary film for the control group) were used. immedia...

marx,s viewpoint with regard to state had ever been an controversial discussion. he has two important viewpoint about existing state from political sociology viowpiont. one of that state depends of them relative independent from classes. in this article we tried to consider only the first marx,s viowpiont that class dependency on state in it. where is the basis of state, why he belive it depend...

based on the carnahan and starling hard sphere equation of compressibility, an equation of state has been derived. conditions that must be met by all equations of state are applied in order to obtain attractive term or non - ideal compressibility term of the equation. second virial coefficient and acentric factor arc used in the derivation of the equation of state. in this equation, compressibi...

This paper provides a briefdescription ofthe rationale behind steady-state modelling, and ofthe implementation ofthe ECOPATH II software system, a system for straightforward construction, parametrization, and balancing of steady-state trophic models of(aquatic) ecosystems. ECOPATH II is written for MS DOS computers and is available as a public domain software from the ICLARM Software Project. E...

The importance of object state testing is illustrated through a simple example. We show that certain errors in the implementation of object state behavior cannot be readily detected by conventional structural testing, functional testing, and state testing. We describe an object state test model and outline a reverse engineering method for extracting object state behaviors from C++ source code. ...

ph control is a challenging problem due to its highly nonlinear nature. in this paper the performances of two different adaptive global linearizing controllers (glc) are compared. least squares technique has been used for identifying the titration curve. the first controller is a standard glc based on material balances of each species. for implementation of this controller a nonlinear state est...
