An auto-switch for multisampling of a wire beam electrode corrosion monitoring system

An auto-switch device has been designed, constructed, and tested for multisensor corrosion measurements. The auto-switch is able to connect/disconnect the selected wire beam electrode and/or electrode pairs under computer control. A computer controlled analog switch-array consisting of 100 inputs has been used as an essential part of the switch bank. The switch-bank is an essential component of a corrosion-monitoring instrument that is expected to find wide application in industry. The performance of the switch-bank is discussed and its effect on the signals is illustrated.

Narrative inquiry and auto-ethnography: Interpretive approaches to research

Hermeneutic phenomenology informed two qualitative methodologies used in my doctoral research: narrative case studies and auto-ethnography. Through these methodologies I investigated the phenomenon of place and identity in visual artistic practice. Four narrative case studies of four artists were developed using experience-focused narrative inquiry and thematic analysis. Auto-ethnography was used to investigate the phenomenon of place and identity within my own practice as visual artist. This involved analysis of my artworks that encompassed place and identity and writing from different contexts of my past. Rather than relying on memory recall. This became textural writing in the phenomenon rather than describing what I already knew. This enabled me to challenge conventional ways of telling my story (big stories) and produced “small stories” from which new insights could be interpreted. The insights gained from my auto-ethnography in turn assisted me to encourage story telling to find the small stories of my artist participants.

Auto-amputation of the tongue associated with flupenthixol induced extrapyramidal symptoms.

We report a case of tongue auto-amputation in a mentally retarded patient after a flupenthixol injection. Four days after flupenthixol administration, the patient developed orolingual dyskinetic movements involving mainly tongue biting and protrusion. Self-mutilation in this case may be secondary to flupenthixol induced acute atypical orolingual dyskinesia in the face of mental retardation.
