L- and M-Shell X-Ray Production Cross Sections of Neodymium Gadolinium, Holmium, Ytterbium, Gold and Lead by 25-MeV Carbon and 32-MeV Oxygen Ions

Andrews, Mike C., 1949- 08 1900 (has links)
L- and M-shell x-ray production cross sections have been measured for thin solid targets of neodymium, gadolinium, holmium, ytterbium, gold, and lead by 25 MeV 12/6C^q+ (q=4,5,6) and by 32 MeV 16/8O^q+ (q=5,7,8). The cross sections were determined from measurements made with thin targets (< 2.5 μg/cm2). For projectiles with one or two K-shell vacancies, the target x-ray production cross sections were found to be enhanced over those for projectiles without a K-shell vacancy. The sum of direct ionization to the continuum (DI) plus electron capture (EC) to the L, M, N... shells and EC to the K-shell of the projectile have been extracted from the data. The results are compared to the predictions of first Born theories, i.e., plane wave Born approximation for DI and Oppenheimer-Brinkman-Kramers formula of Nikolaev for EC and to the ECPSSR approach that accounts for Energy loss and Coulomb deflection of the projectile as well as for Relativistic and Perturbed Stationary States of inner shell electrons.

Fitness Dependent Dispersal in Intraguild Predation Communities

Ryan, Daniel P 22 July 2011 (has links)
A model of a three species intraguild predation community is proposed. The model is realized as a system of cross-diffusion equations which allow the intraguild prey species to adjust its motility based on local resource and intraguild predator densities. Solutions to the cross-diffusion system are shown to exist globally in time and the existence of a global attractor is proved. Abstract permanence theory is used to study conditions for coexistence in the ecological community. The case where the intraguild prey disperses randomly is compared to the case where the intraguild prey disperses conditionally on local ecological fitness and it is shown that the ability of the intraguild prey to persist in the ecological community is enhanced if the intraguild prey utilizes a movement strategy of avoiding areas with negative fitness. A finite element scheme is used to numerically simulate solutions to the system and confirm the analytical results.

The Study of The Pressure Dependence of Foreign Gas on the Fluorescence of Nitric Oxide

Lai, Chin-Min 31 July 2001 (has links)
The photoabsorption cross sections of NO have been measured in the wavelength range 150~200nm, and the cross sections deviation from Beer-Lambert law due to the insufficient resolution of light source is discussed qualitatively. From the steady state approximation of quenching reactions, the pressure dependence of foreign gas on the ratio of absorption intensity to the fluorescence intensity is derived. Furthermore, the non-Stern-Volmer behaviors of the C2£S(n=0) state of NO were discussed by assuming the non-predissociated (J<9/2) and the predissociated (J>9/2) rotational levels following different quenching mechanisms.

Modeling cross-classified data with and without the crossed factors' random effects' interaction

Wallace, Myriam Lopez 08 September 2015 (has links)
The present study investigated estimation of the variance of the cross-classified factors’ random effects’ interaction for cross-classified data structures. Results for two different three-level cross-classified random effects model (CCREM) were compared: Model 1 included the estimation of this variance component and Model 2 assumed the value of this variance component was zero and did not estimate it. The second model is the model most commonly assumed by researchers utilizing a CCREM to estimate cross-classified data structures. These two models were first applied to a real world data set. Parameter estimates for both estimating models were compared. The results for this analysis served as a guide to provide generating parameter values for the Monte Carlo simulation that followed. The Monte Carlo simulation was conducted to compare the two estimating models under several manipulated conditions and assess their impact on parameter recovery. The manipulated conditions included: classroom sample size, the structure of the cross-classification, the intra-unit correlation coefficient (IUCC), and the cross-classified factors’ variance component values. Relative parameter and standard error bias were calculated for fixed effect coefficient estimates, random effects’ variance components, and the associated standard errors for both. When Model 1 was used to estimate the simulated data, no substantial bias was found for any of the parameter estimates or their associated standard errors. Further, no substantial bias was found for conditions with the smallest average within-cell sample size (4 students). When Model 2 was used to estimate the simulated data, substantial bias occurred for the level-1 and level-2 variance components. Several of the manipulated conditions in the study impacted the magnitude of the bias for these variance estimates. Given that level-1 and level-2 variance components can often be used to inform researchers’ decisions about factors of interest, like classroom effects, assessment of possible bias in these estimates is important. The results are discussed, followed by implications and recommendations for applied researchers who are using a CCREM to estimate cross-classified data structures. / text

Swedish management in a cross-cultural perspective : A qualitative study of how Swedish managers adapt their management to foreign cultures.

Melin, Rebecka, Emma, Rutholm January 2015 (has links)
The purpose of this thesis is to analyze and study how Swedish managers manage cross-cultural differences and how their management style is adapted to foreign cultures. This thesis could contribute to getting a deeper understanding of how Swedish management is adapted to foreign cultures. The empirical material in this study has been collected through qualitative interviews with four different Swedish managers with experience of managing abroad. The theoretical framework is based on the concepts cultural dimensions, management and cross-cultural adaptation which also are the three concepts in our conceptual framework. The conceptual framework is present in the interview template, the empirical chapter and the analysis to provide the thesis with a clear line of argument. The empirical chapter describes how the Swedish managers have dealt with the challenges of working in a foreign culture and how they have adapted their management to another culture.In the analysis the empirical material is analyzed with the help of the theoretical framework. In the analysis the effect of cultural dimensions is discussed in relations to Swedish management and which challenges a Swedish manager encounter when managing abroad. The conclusion indicates that Swedish managers seem to adapt their management style to the extent that they have to be more clear and strict in their management and they have to make a lot more decisions. It seems to be a linkage between to what extent Swedish mangers have to adapt their management style to the local culture and what kind of management position they have.
