  • What is a Spectrometer?

    The characteristics of a white LED light differs greatly, when compared to a yellow CFL. Without any special tools, one can see that the LED emits a clear white color, while the CFL generates yellow light. Going one step further, using a spectrometer, one will be able to “dissect” the light sources and see that they are composed of other colors in the visible light spectrum, such as ...

  • Research on the economic consequences of the health effects of air pollution in the UK: its methodological, meta-analytical and innovative aspects

    Epidemiological research has identified that there exists a correlation between days of high air pollution and the timing of death for large numbers of individuals. Before economic values can be attached to these impacts, however, greater information is required on the extent of life lost and the socio-economic characteristics of those at greatest risk. It may be more fruitful to base willingness ...

  • SPADE-2: The Soil Profile Analytical Database For Europe

    1. The European Soil Database – ESDB – (version 1.0) has been developed over the last two decades through the efforts of the European Soil Bureau Network. 2. The database has four main components: the 1:1,000,000 Soil Geographical Database of Europe (SGDBE v. 3.2.8.0), the European Soil Profile Analytical database, SPADE-1 (v. 2.1.0.0), the European Pedo-Transfer Rules database (v. 2.0), The ...


  • Ultra-trace arsenic speciation at Columbia Analytical

    Ultra-trace speciation of arsenic and other metals is performed using a variety of techniques tailored to the specific combination of species, matrix, and detection limits required. Currently, two analytical systems are applied: Ion Chromatography-Inductively Coupled Mass Spectrometry (IC-ICP-MS) and Hydride Generation-Cryogenic Gas Chromatography-Flame Atomic Absorption Spectrometry ...


  • Analytical Testing for Corexit Dispersants Used in the Gulf Spill

    The analysis of various sample matrices (seawater, sediment, tissue) to determine concentrations of Corexit dispersants used in the Gulf spill requires the use of one or more of the components in the dispersant as a tracer. The primary active ingredient (i.e. the primary surfactant) in the Corexit products is Dioctyl Sulfosuccinate Sodium Salt (DOSS). The other primary ingredients function as ...


  • The research on the measurement of corporate technology capability

    There is a consensus among scholars supporting the notion that firms that receive technology transfer need a certain level of technological capability to transfer technology effectively from external sources. However, technology capability has many different dimensions and is difficult to measure. Thus, there is no complete set of indicators that can measure the degree of technology capability in ...

  • Research on dynamic characteristics of the cylinder block

    The dynamic characteristics of the cylinder block directly influence the vibration and noise of the internal combustion engine (ICE). Modal analysis of the cylinder block is very helpful for its system identification and performance improvement. This paper refers to a basic study on the experimental and analytical methods for the reduction of resonant vibration in each vibration mode on three ...
