The fabrication of high quality graphene has become the main interest in current chemical vapour deposition (CVD) method due to the scalability for mass production of graphene-based electronic devices. The quality of graphene is determined by defect density, number of layers and properties changed such as electron mobility, transparency and conductivity as compared to the pristine graphene. Here, we did a study on the effects of reaction conditions such as methane, CH4 concentration and deposition time towards the quality of graphene produced. We found that by lowering both CH4 concentration down to 20% and deposition time to 5 min, a better quality graphene was produced with higher I2D/IG ratio of 0.82 compared to other reaction condition. Through the analysis, we concluded that there are two important parameters to be controlled to obtain high quality graphene.
Psychotherapeutic management of a potential spirit medium (shaman) in a modern University Hospital setting in Malaysia is described. Magical thinking, projection and spirit possession (trance state) occur during management. Discussion of management was based on what Heinz Wolff described as the psychotherapist's functions of (1) psychodynamic understanding; (2) the therapeutic function; and (3) the developmental function. This patient did not conform to the general criteria of a suitable patient for psychotherapy. But her willingness to engage in therapy contributed to a satisfactory outcome. The therapist's growth in cross-cultural therapeutic encounter seems to be prominent.
Distress and psychiatric morbidity in cancer patients are associated with poorer outcomes including mortality. In this study, we examined the prevalence of psychiatric morbidity and its association with cancer survival over time.
Hypokalemia is not an isolated disease but an associated finding in a number of different diseases. It is also a commonly neglected condition among patients with acute acetaminophen overdose.
