Electrostatic charging artefacts in Lorentz electron tomography of MFM tip stray fields

Using the technique of differential phase contrast (DPC) Lorentz electron microscopy, the magnetic stray field distribution from magnetic force microscopy (MFM) tips can be calculated in a plane in front of the tip using tomographic reconstruction techniques. Electrostatic charging of the tip during DPC imaging can significantly distort these field reconstructions. Using a simple point charge model, this paper illustrates the effect of electrostatic charging of the sample on the accuracy of tomographic field reconstructions. A procedure for separating electrostatic and magnetic effects is described, and is demonstrated using experimental tomographic data obtained from a modified MFM tip

Strategies for Successfully Marketing and Stabilizing the Occupancy of Mixed-Income/Mixed-Race Properties: A Case Study of Parkview Terrace in Poway, California

Parkview Terrace was built in 1998 and is a 92-unit mixed-income, mixed-race property in Poway, California. Poway has grown in just 30 years from a rural farming community with a trailer park image to a very desirable community of multi-million dollar homes with a renowned public school system. It is just 15 miles northeast of San Diego.Although Parkview Terrace's initial tenant eligibility is capped at 50 percent of AMI, long resident tenure -- spurred by an exploding real estate market and plentiful employment -- finds 43 percent of households now at or above 60 percent of AMI. The immediate neighborhood, one of the lower income ones in the city, offers an extraordinary mix of modest residential, retail, municipal, recreational and educational opportunities, all within a few blocks

Das Verbot. Ein empirischer Befund aus psychoanalytischer,\ud entwicklungspsychologischer und evolutionstheoretischer Sicht

Die Ergebnisse einer empirischen Studie mit einjährigen Zwillingen und deren Bezugspersonen lassen darauf schließen, daß Verbote individuelles Verhalten direkt und nachhaltig beeinflussen. Das Verbot wird dadurch als wesentliches Element der Sozialisation empirisch belegt. Ziel dieses Artikels ist es, die individuelle und gesellschaftliche Bedeutung des Ver­bots aus psychoanalytischer, entwicklungspsychologischer und evolutions­theoretischer Sicht zu analysieren. Die Verinnerlichung von Verboten als wichtige Grundlage der Ausbildung von Ich und Über-Ich sowie von da­durch gesteuertem sozialen Verhalten, das in wesentlichen Bereichen un­bewußt organisiert ist, wird diskutiert

Education in Nazi Germany

This essay investigates the sweeping educational reforms that the Nazi government implemented to use elementary education to further its political goals. Along with the major laws concerned, it concentrates on several personal accounts of families and students during this era to better understand how these educational reforms affected Germans. Additionally, it analyzes the Hitler Youth and other such recreational organizations that the Nazis created to continue to mold students’ ideologies. It examines the stories of several people who were children in these organizations and what their impressions were of the groups. Finally, it places these Nazi reforms in the context of the post-1945 period of denazification and reconstruction

A pH Dependant Switch in DHP Oxidation Mechanism

Dehaloperoxidase (DHP) is a multifunctional enzyme found in Amphitrite ornata, a sediment-dwelling marine worm. This enzyme possess the structure of a traditional hemoglobin enzyme and serves as the primary oxygen carrier in A. ornata; however, it also possesses peroxidase and peroxygenase capabilities. These secondary oxidative functions provide a remarkable ability for A. ornata to resist the effects of toxic metabolites secreted by other organisms that cohabit its benthic ecosystem. This study will analyze the novel catalytic switching between peroxygenase and peroxidase oxidation mechanisms employed by DHP in response to pH changes
