Mass spectrometry plays a key role in drug metabolite identification, an integral part of drug discovery and development. The development of high-resolution (HR) MS instrumentation with improved accuracy and stability, along with new data processing techniques, has improved the quality and productivity of metabolite identification processes. In this minireview, HR-MS-based targeted and non-targ...

A single series of representative observations indicates that both the productivity and standing crop of phytoplankton in Fanning Lagoon are much greater than reported in the lagoons of other Pacific atolls. Productivity, as measured by the radiocarbon method, averaged 9.29 mg C/m3/hr, while cWorophyll a averaged 0.548 j.!g/liter. Phytoplankton, principally dinoflagellates with some diatoms and...

Field experiment was conducted to investigate the comparison between two types of ridge (panel and disc) using spaces operational parts (90 110 cm) at speeds (4 2.6 km/hr). First stage from this study identify important dimensions local manufactured (ridge panel) with selecting appropriate material throughout series material, mechanical chemical analyses. Second evaluate performance particular ...

A series of 4 experiments were conducted to investigate ideational productivity. Experiments 1, 2, and 3 were carried out under controlled conditions and involved a test of ideational productivity based on producing different interpretations of a diagram. In the first experiment, the pattern of ideational productivity of adult volunteer participants was studied over 30 min of thinking time. Exp...

The productivity change of a decision making unit (DMU) between two time periods can be evaluated by the Malmquist productivity index. In this study, we propose a method to compute the Malmquist productivity index in several time periods (from the first to the last periods) on interval data in data envelopment analysis (DEA). Then, the obtained Malmquist productivity index is compared with Malm...
