Strain-balanced InAs/InAs(sub 1-x)Sb(sub x) type-II superlattices (SLs) on GaSb substrates with 0.27 /= x /= 0.33 were grown by molecular beam epitaxy and demonstrated photoluminescence (PL) up to 11.1 micro m. The calculated SL bandgap energies agree with the PL peaks to within 5 meV for long-wavelength infrared samples (9.5, 9.9, and 11.1 micro m) and to within 9meV for a mid-wavelength infrared sample (5.9 micro m). X-ray diffraction measurements reveal average SL mismatches of less than 0.2%, and the PL full-width-at-half-maximums increase with the mismatch, confirming the importance of strain-balancing for material quality., Published in the Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures, v30 n2 article ID 02B107-1, Mar/Apr 2012.

Ein über 12 Jahre brütend kontrolliertes Steinkauz-Weibchen zeigte eine hohe Brutortstreue und Partnertreue über drei Jahre. In 11 Brutjahren legte es 49 Eier, aus denen 36 Nestlinge das Beringungsalter (10.-14. Lebenstag) erreichten. Ab dem Alter von 10 Jahren wurden durchschnittlich 0,8 Eier pro Jahr weniger gelegt. Von den 36 Nachkommen siedelten sich 2 Weibchen und 1 Männchen selbst wieder in der untersuchten Population an. Bis zum Alter von 9 Jahren lässt sich ein deutlicher Zusammenhang zwischen Bestandsdichte der Feldmaus als Hauptbeute und dem Termin des Legebeginns feststellen., A female of the little owl has been observed breeding over 12 years in a Southwestern German study area. The bird showed a high degree of nest site fidelity and a partner fidelity over three years. During 11 breeding periods the female incubated 49 eggs with a breeding success of 36 nestlings which reached the age of ringing (day of life 10 - 14). From the age of 10 years onwards average clutch size was reduced by 0.8 eggs per year. Out of 36 offspring two females and one male were recruited to the same studied population. Up to an age of 9 years a clear relationship persists between density of the main prey, the field vole Microtus arvalis and the date of the first egg.

This research in support of the Air Force Research Laboratory Materials and Manufacturing Directorate was conducted at Wright-Patterson AFB, Ohio from 27 February 2007 through 22 July 2007. The task of the project focused on photoluminescence (PL) experiments on various semiconducting samples grown with Molecular Beam Epitaxy (MBE) at MLPS. Quantum structures and quantum dots composed of InAs, GaAs, and GaSb have been investigated. The structures are potential candidates for highly sensitive infrared (IR) detectors and the knowledge of their optical performance such as PL is of considerable importance for the AF and the community in general., Original report contains color.

During this era in which budget shortfalls are commonplace, it is necessary for program sponsors to have an effective means of estimating and justifying their budgets. Program sponsors rely on cost analysts to complete and defend these detailed budget estimates. The Operation and Support (O&S) portion of a missile system's life cycle accounts for approximately 78%¹ of the total program's costs. Thus establishing a structured means of estimating a missile system's O&S cost will greatly aid cost analysts. Through use of the Operation and Support Cost AnalyzeR (OSCAR) System, cost analysts and program sponsors will be provided with defendable budgets. The OSCAR system consists of an OSCAR database², OSCAR model³, and methodology on how to maintain the OSCAR system. The design and development of the OSCAR system including the OSCAR model and OSCAR database was completed by Rosemarie Bolha as part of the Project Report submitted to the Faculty of the Virginia Polytechnic Institute and State University. The OSCAR database consists of Cost Estimating Relationships (CERs) for all of the O&S sub-elements. The majority of the CERs were statistically derived from the data collected from numerous missile systems. This database is used to support and supplement the detailed analyses completed by the OSCAR model. The OSCAR model predicts any missile system's O&S cost. The OSCAR model provides budget estimates and supporting information quickly and reliably. The OSCAR model is designed with the capability to predict costs for two or three levels of maintenance, calculate a missile's recertification schedule based on a variety of system-in-service-times, and provide the user with both a detailed and a summarized Logistics Requirement Funding Plan‘ report. By incorporating state-of-the-art system engineering concepts, the OSCAR system is designed with considerations for user friendliness, fulfillment of end users needs, and flexibility. One such concept is a six step analytical appr
