The application of mass spectrometry to steroids has been extensively developed since its inception in 1956. Detailed studies based on pure steroids and their isotope labelled analogues have established the major pathways of fragmentation under electron impact. The resulting correlations have been of great value in the analytical characterization of steroids and their metabolites. The combination of mass spectrometry with gas chromatography is particularly powerful: the latter technique reduces the complexity of samples, and provides independent characterization by virtue of retention regularities. These features are essential for distinguishing many stereoisomeric or otherwise closely related steroids. Modifications of functional groups can augment the utility of mass spectrometry in qualitative and quantitative analysis. Derivatives may be chosen to alter fragmentation modes, or to produce informative shifts in ion masses within an essentially unchanged fragmentation pattern. Enhancement of molecular ion abundance is usually achievable with derivatives, or by means of milder ionization techniques such as chemical ionization.

Attitudes towards tax compliance (willingness to comply) Indonesian society is still low. Required an innovative tax dissemination to increase it. The purpose of this study was to determine whether the tax dissemination based on Fogg Behavioral Model (FBM) approach may increase wiliingness to comply. The FBM based tax dissemination asserts that for a person to perform a target behavior, which is a willingness to comply, he or she must be sufficiently motivated, have the ability to perform the behavior, and be trigerred, to perform the behavior. This research is a combination of qualitative and quantitative analysis of statistical data results of the questionnaire, interviews, and observations of the respondent and the experimental process of dissemination. The method used in this study is a quasi experimental with patterns of nonequivalent control group (pretest-post which is not equivalent). Based on the results of data analysis, interviews and observations of the respondent and the experiment, this research showed that theFBMbasedtaxdissemination hasapositiveimpactto willingnesstocomplyofthetaxpayers.
