And this course’s purpose is just that. Through exploring today’s complex business problems, students will develop a critical thinking attitude while learning how to apply an array of critical thinking skills. Emphasis will be placed on using logical reasoning supported by qualitative and quantitative evidence to identify problems, evaluate alternatives, and justify decisions. It is expected that students will become better listeners, more capable communicators – both in writing and speaking – as well as better at reflecting upon their own thinking. The class is based on the premise that critical thinking and communication skills are best learned through practice. Therefore, repeated writing and speaking exercises will be core components of the class, and students will receive training and practice as well as instructor and peer feedback to help them improve their skills

Reggie Edgerton. Modulation of MHC isoforms in functionally overloaded and exercised rat plantaris fibers. J. Appl. Physiol. 83(1): 280–290, 1997.—The effects of 1 and 10 wk of functional overload (FO) of the rat plantaris with (FOTr) and without daily endurance treadmill training on its myosin heavy chain (MHC) composition were studied. After 1 and 10 wk of FO, plantaris mass was 22 and 56% greater in FO and 37 and 94% greater, respectively, in FOTr rats compared with age-matched controls. At 1 wk, pure type I and pure type IIa MHC fibers were hypertrophied in FO (39 and 44%) and FOTr (70 and 87%) rats. By 10 wk all fiber types comprising >5% of the fibers sampled showed a hypertrophic response in both FO groups. One week of FO increased the percentage of hybrid (containing both type I and type IIa MHC) fibers and of fibers containing embryonic MHC. By 10 wk, the percentage of pure type I MHC fibe...

The amendment, which was adopted and became effective March 30, 1946, allows a direction charging the executor or administrator with a mortgage or other lien on real property devised or descended to be express or by necessary

Good agreement has been found between these theoretical results and the available experimental values, especially for the firm assignments of R(28) A 0 2 and P(33) A 1 2 for SF 6 absorption nearest the CO 2 P(14) and P(18) laser emissions, respectively.

A computational evaluation of altitude profiles of the equilibrium monomeric-dimeric CO2 fractions in the atmosphere of Venus
Thermochimica Acta, 1992

The dimerization equilibrium constant is combined with observed height profiles of temperature and pressure in the atmosphere of Venus in order to derive the equilibrium dimeric mole fraction. In all the three treatments it is found that the mole fraction decreases with increasing height. The decrease is interpreted in terms of competition between temperature and pressure effects. The dimeric mole fraction should be at least 4% at the surface of Venus and, thus, is important in the planning of future observations.
The equilibrium constants of formation of the gas phase species Ar-N2 (T-shape and linear isomer,... more The equilibrium constants of formation of the gas phase species Ar-N2 (T-shape and linear isomer, their equilibrium mixture) are evaluated from recently computed quantumchemical data. It is shown that the isomeric relative stabilities can be interchanged so that the isomers can exhibit comparable concentrations in some temperature regions. The computed overall equilibrium constant is combined with the observed temperature and pressure protiles in Titan's atmosphere and the altitude profile of the heterodimer mole fraction in equilibrium with N, and Ar is estimated. The mole fraction decreases with altitude and close to Titan's surface is found to be 8 X lo-'%.
Selective carrier-mediated cesium transport through polymer inclusion membranes by calix[4]arene-crown-6 carriers from complex aqueous mixtures
Radiochimica Acta, 2002

The PIM matrix consisted of cellulose triacetate and ortho-nitrophenyloctyl ether. Special attention was paid to PIM performance employing complex source-phase mixtures, including simulant solutions of acidic nuclear wastes present at Idaho National Engineering and Environmental Laboratory. PIMs exhibited highly efficient and selective Cs+ transport under competitive conditions. Membranes containing calix-monocrown carrier exhibited slightly less efficient but more selective Cs+ transport than those with calix-biscrown carrier. PIMs with bis(dodecyloxy)calix[4]arene-crown-6 exhibited excellent stability in terms of carrier loss to the aqueous phase. The variation of cesium transport with composition of aqueous phase was adequately described by a diffusion-limited transport model.
Selection rules and electric-dipole transition moments between rotational substates in excited vi... more Selection rules and electric-dipole transition moments between rotational substates in excited vibrational states of 'spherical-top molecules have been derived. The explicit dependence of these moments on rotational and vibrational quantum numbers has been calculated. These results, which are generally applicable, have been used to analyze the concept of a multiple-photon pathway in the nV3 "ladder" of SF 6 . It will be shown that some ladder schemes must have "rung gaps" in their sequence of proposed strongly allowed electric-dipole transitions. There is considerable interest in the mechanism of collisionless multiple-photon dissociation of polyatomic molecules by laser radiation.' In particular, much effort has been expended to understand this process in which SF 6 is irradiated by a CO 2 laser at 10.6 ,m. 2 4 Recent theoretical work 2 ' 3 has emphasized anharmonic splittings in the V3 manifolds based on one of the infrared-active fundamentals of SF 6 . The purpose of this Letter is to derive selection rules and electric-dipole transition moments for certain rotational-vibrational (RV) excited states in spherical-top molecules. These results have been applied to models of multiple-photon pathways in the nv 3 "ladder" of SF 6 .
Measurements of nitrogen-, hydrogen- and helium-broadened widths of methane lines at 9030–9120 cm-1
Journal of Quantitative Spectroscopy and Radiative Transfer, 1985
Pressure-broadened widths of vibration-rotation lines of both 12CH4 and 13CH4 have been measured ... more Pressure-broadened widths of vibration-rotation lines of both 12CH4 and 13CH4 have been measured at very high spectral resolution in the R-branch of the 3ν3 overtone. The broadening gases were N2, H2 and He, as well as a mixture of H2 and He. Results are presented as averages for J-multiplets at ambient temperature. The overall R-branch values for line widths in 12CH4-N2, 12CH4-H2, 12CH4-He, 12CH4-H2+He and 13CH4-H2 are 0.0711 ± 0.0064, 0.0687 ± 0.0030, 0.0429 ± 0.0012, 0.0545 ± 0.0030 and 0.0678 ± 0.0054 cm-1 atm-1, respectively.
Theory of vibration-rotation interactions in spherical top molecules
Journal of Molecular Spectroscopy, 1965
Abstract The possibility of a new overtone band in the infrared absorption spectrum of tetrahedra... more Abstract The possibility of a new overtone band in the infrared absorption spectrum of tetrahedral XY4 molecules is investigated theoretically. This band is associated with the E vibrational part of the first overtone of an infrared active fundamental. The new band is active only through vibration-rotation interactions. Its intensity is very small compared to that of the F2 vibrational part of the same overtone. Formulas for relative intensities and matrix elements of the Hamiltonian are calculated. The selection rules imply a single P, Q, and R branch. The tetrahedral splittings of the vibration-rotation levels are determined by only two parameters: Dt and γ′ 3t ≡ 1 3 (Z 3s + 6Z 3t ) . A possible favorable case for the observation of the band may be CD4 at about 4700 cm−1. With the assumption that γ′3t ⪢ Dt, the tetrahedral splittings and relative intensities are calculated numerically through J = 7 for this case.

The treatments are of an ab initio type with the second and fourth order Møller‐Plesset perturbation techniques and a basis set superposition error evaluation. The computed dimerization equilibrium constant is combined with observed height profiles of temperature and pressure. In six treatments considered it is found that the mole fraction decreases with increasing height. Various approximations suggest the dimeric mole fraction at the Jupiter 1 atm pressure level between 0.04 and 1.06%.
