Excited with the reaction to the latest product development, a jubilant Keith Dale, Elektralite's International Sales and Marketing Manager said "We had high expectations for the CP20xt because it was designed to surpass the exacting requirements of the US market. We also spent a not insignifi cant amount of time, effort and money to ensure that we delivered the product in a package that exceeded the current standards for build quality and styling". Remarked Norman Wright, Elektralite Vice President "It has been a fantastic Fair for us and well worth the effort. We were able to confi rm the appointment of several new dealers on the strength of our product range and expect to announce more positive news in the very near future".
The diffusion of a binary solvent mixture into cross-linked poly (butadiene) (PBD) was observed using fast scan FT-IR imaging spectroscopy. Spatial correlation of solvent ingress and polymer swelling was established with a temporal resolution of 20 s. Binary solvent mixtures included a good-good solvent pair of benzene-cyclohexane (50/50 wt%) and a good-poor solvent pair of toluene-methanol (50/50 wt%). A set of FT-IR images was collected over time, from which the profiles of solvent ingress and polymer swelling were extracted. The Boltzmann transformation, which explains diffusion phenomena with respect to both time and position simultaneously, was used to obtain a curve, which indicates that benzene and cyclohexane diffuse similarly, but toluene and methanol have different diffusion behavior. The good-good solvent pair (benzene-cyclohexane mixture) ingressed into polymer together, while the good-poor solvent pair (toluene-methanol mixture) showed independent ingression behavior. The good solvent (toluene) aggressively diffused into polymer while the poor solvent (methanol) remained in solution.
Agency theorists argue that organizations typically get little value from using employees and that they should instead use nonemployees operating fully as residual claimants. Yet, even in a context where those theorists would predict virtually no employees—taxicab organizations—they are common. What drives the use of employment relationships in these organizations? The authors show how employment relationships are linked to firm capabilities and strategic opportunities in a sample of taxicab organizations, relying on arguments about the linkage of employment to the internal liquidity of labor, organizational routines, and internal cooperation. The theoretical arguments and findings suggest what organizations gain by having employment relationships and show that integrating the agency theoretic argument with the other theoretical arguments leads toward a resource-based view of strategy and human resources. The authors highlight the importance of embedding arguments on the internal management of human resources in the strategic and competitive context in which organizations operate. Their arguments also have implications for the resource-based approach to strategy in mapping the resource space of human assets in organizations and, within that space, directing attention to how organizations gain sustainable competitive advantage through managing human resources.
FT-Raman spectrometry has advanced significantly through the combination of CW Nd: YAG lasers, high sensitivity near-infrared detectors, and state-of-the-art filter technology. Obtaining fluorescence-free spectra through nearinfrared excitation has now become practical.
Numerical integration of the coupled field-material system equations shows self-focusing when coherent pulses propagate through resonant absorbers. The effect appears to be distinct from self-focusing associated with adiabatic following.

The infrared absorption spectrum of carbon suboxide vapor has been studied under low dispersion in the region from 2μ to 25μ. The vibrational bands observed may be satisfactorily accounted for on the basis of a linear symmetric structure for the carbon suboxide molecule, in agreement with evidence obtained from Raman spectra and from electron diffraction investigations.
THE possibility of using the Raman effect for quantitative analysis depends upon two conditions: (1) The components of the mixture in question should possess distinguishable spectra, a requirement depending on the nature of the molecules. (2) The photographed spectra should be sufficiently intense and the background clear enough to provide good microphotometer measurements. The accompanying account concerns an investigation of these conditions in the case of amino acid solutions.
THE purpose of this letter is to report some measurements of Raman frequencies in solutions of glycine, alanine, tyrosine and cystine, which have been observed as a preliminary to the development of a spectroscopic method of analysis for molecules of this class.
A spectrometer of large aperture employing a reflection grating of the echelette type ruled to concentrate radiation in the region of the 1st order of 90\ensuremath{\mu} has been applied in the spectral range from 60 to 125\ensuremath{\mu}. The resolving power was several times that hitherto obtained in this region. The pure rotation absorption spectra of water vapor and of the gases N${\mathrm{H}}_{3}$ and P${\mathrm{H}}_{3}$ have been investigated. In the case of N${\mathrm{H}}_{3}$ the absorption lines shown as single in the observations of Badger and Cartwright have been found under the higher resolution of the present work to be doublets with a doublet separation of 1.33 ${\mathrm{cm}}^{\ensuremath{-}1}$. Despite the similarity of structure of the molecules P${\mathrm{H}}_{3}$ and N${\mathrm{H}}_{3}$ the pure rotation lines of P${\mathrm{H}}_{3}$ exhibit no trace of a doubling. The frequencies of the P${\mathrm{H}}_{3}$ lines and the mid-frequencies of the N${\mathrm{H}}_{3}$ doublets have been shown to agree very accurately with formulas of the type ${{\ensuremath{\nu}}_{J}}^{J\ensuremath{-}1}=BJ\ensuremath{-}D{J}^{3}$. Determinations of the moments of inertia $A$ of N${\mathrm{H}}_{3}$ and P${\mathrm{H}}_{3}$ have been made and in the case of N${\mathrm{H}}_{3}$ the measurement of the doublet separation has led to a slight revision of the values for the moment of inertia $C$ and for the molecular dimensions obtained by Dennison and Uhlenbeck.
An open arc of 80 amperes between a carbon rod and tin pool has been used as source, and observations have been made using a grating spectrometer and thermopile. The wave-lengths of forty-five new lines of the tin arc spectrum in the region from 1\ensuremath{\mu} to 3\ensuremath{\mu} have been measured, and rough determinations of the relative intensities of the strong lines have been made. Nine energy levels of the $5{s}^{2}5p6p$ configuration have been found, which with the one found by Green and Loring complete the set. Three of the four levels of the $5{s}^{2}5p(^{2}P_{\frac{1}{2}})4f$ set have been found, and the fourth,${3}_{3}$, has been accounted for as lying too close to ${4}_{2}$ for resolution. With the fixing of these levels all the strong infra-red lines have been classified. The finding of the levels $5p(^{2}P_{\frac{1}{2}})4f{4}_{2}$ and $5p(^{2}P_{\frac{1}{2}})5f{4}_{2}$ has made possible a good determination of the absolute term values.
