background: induced abortion is not only a serious threat for women’s health, but also a controversial topic for its ethical and moral problems. we aimed to evaluate the relationship between neutralization techniques and attempting to commit abortion in married women with unintended pregnancy. methods: after in-depth interviews with some women who had attempted abortion, neutralization themes w...

an adaptive input-output linearization method for general nonlinear systems is developed without using states of the system. another key feature of this structure is the fact that, it does not need model of the system. in this scheme, neurolinearizer has few weights, so it is practical in adaptive situations.  online training of neurolinearizer is compared to model predictive recurrent training...

background and aims: canine distemper (cd) is a deadly infectious disease of canidae family. cd is a multi-systemic viral disease and is specified by wide range of clinical symptoms. the manifestations are not always indicative of cd, therefore a laboratory confirmation is necessary for suspected cases. materials and methods: different clinical specimens of 19 cd suspected unvaccinated dogs wer...

In pH reactors, determination and control of pH is a common problem concerning chemical-based industrial processes due to the non-linearity observed in the titration curve. We introduced a modified multiregional fuzzybased control system to overcome the complexity of precise control of pH. In order to compensate for the experimental inaccuracies in measurements of pH in-situ values; an observer...

The reaction of bacteriophage T4 with l-fluoro-2,4-dinitrobenzene resulted in a covalent binding of 2,4-dinitrophenyl (D N P) determinants to the phage. From the kinetics of inactivation re­ flecting the coupling process it is concluded that attachment of more than one D N P group to the critical site(s) of the phage is required for inactivation (multi-hit reaction). Contrary to this the neutra...

In this paper, a new architecture combining dynamic neural units and fuzzy logic approaches is proposed for a complex chemical process modeling. Such processes need a particular care where the designer constructs the neural network, the fuzzy and the fuzzy neural network models which are very useful in black box modeling. The proposed architecture is specified to the pH chemical reactor due to ...
