Various public databases provide Arabidopsis gene information via the internet. It is useful to abstract information obtained from such databases. We have developed the KAGIANA tool, which allows a user to retrieve summary information obtained from selective databases and to access pages for a gene of interest in those databases. The tool is based on Microsoft Excel and provides several macro p...
asmari formation was deposited in the foreland zagros basin (southwest iran). in this research, biostratigraphy related to the asmari formation in north of khorram abad, robat namaki section, is discussed. in the studied stratigraphic section, the asmari formation overlies the shahbazan formation and underlies gachsaran formation and consists of cream to gray medium to thick limestone and marl....
Background Plant tissue culture is a biotechnology particularly relevant to plant genetic transformation. The ability of in vitro regeneration is one of the requirements for the production of usable plants in breeding programs [1]. As each genotype has a specific regeneration potential, several protocols have been developed with the aim of developing methodologies that can speed up the germinat...
Features for a new application in pattern recognition are presented. The objects to be classiied are coccoliths (marine microfos-sils). Since the objects diier both in their outline and in their internal structure the features developed take into consideration both kinds of variability. The features concerning the internal structure are computed on the grey-value images produced by a scanning e...
During the past decade, Environmental and Field Emission Scanning Electron Microscopes have been used at the NASA/Marshall Space Flight Center to investigate freshly fractured interior surfaces of a large number of different types of meteorites. Large, complex, microfossils with clearly recognizable biological affmities have been found embedded in several carbonaceous meteorites. Similar forms ...
Initially, Raman spectroscopy was a specialized technique used by vibrational spectroscopists; however, due to rapid advancements in instrumentation and imaging techniques over the last few decades, Raman spectrometers are widely available at many institutions, allowing Raman spectroscopy to become a widespread analytical tool in mineralogy and other geological sciences. Hyperspectral imaging, ...
Der Beitrag stellt auf Basis einer ersten empirischen Untersuchung den Status Quo des Geschäftsprozessmanagements (GPM) in der kommunalen Wirtschaftsförderung dar. Obwohl GPM in der öffentlichen Verwaltung ein Instrument von wachsender Bedeutung darstellt, wurde der Bereich kommunaler Selbstverwaltung hierzu bislang wissenschaftlich nicht evaluiert. Die vorliegende qualitative Voruntersuchung b...
