EX MACHINA: THE LOCKHEED F-104G STARFIGHTER, THE FEDERAL REPUBLIC OF GERMANY, AND THE EUROPEAN MILITARY AVIATION SECTOR 1955-1975

This dissertation articulates the Federal Republic of Germany’s critical role in establishing and sustaining the modern multinational European aviation sector. It demonstrates how Bonn employed its 1959 acquisition of the Lockheed F-104G Starfighter combat aircraft to take advantage of the Eisenhower administration’s efforts to reduce the US military presence in Europe and achieve strategic goals of military, political, and economic primacy within NATO through multinational cooperation and consortium building. In fostering the European Starfighter consortiums and their successors, West Germany embraced a leadership role that saw it build one of NATO’s largest air forces and become a primary political and economic driver of the continent’s multinational military-aviation projects. This dissertation is predicated on intensive archival research conducted in Germany, Belgium, and the United States. This work employs economic, political, and military historical lenses of analysis to argue that the Starfighter’s legacy represents a long-term success that allowed the Federal Republic to leverage a role of normalized leadership within a decade of joining NATO, boost its moribund aviation sector, and take a leading role in contemporary multinational aviation concerns such as the Panavia Tornado, Eurofighter Typhoon, and Airbus Space and Defense.Histor

Manufacturing and properties of biobased thermoplastic composites from poly(lactid acid) and hazelnut shell wastes

This is the peer reviewed version of the following article: Balart, J.F., Garcia-Sanoguera, David, Balart, Rafael, Boronat, Teodomiro, Sanchez-Nacher, Lourdes. (2018). Manufacturing and properties of biobased thermoplastic composites from poly(lactid acid) and hazelnut shell wastes.Polymer Composites, 39, 3, 848-857. DOI: 10.1002/pc.24007 , which has been published in final form at [Link to final article using the DOI]. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving.[EN] Poly(lactic acid), PLA-based green composites were obtained with hazelnut shell flour (HSF) derived from the food industry thus leading to fully biodegradable materials with attracting properties. The hazelnut shell flour content varied in the 10-40wt% range. An increase in the degree of crystallinity with increasing HSF was detected, mainly due to the nucleating effect of lignocellulosic particles. The thermodimensional stability was noticeably improved with increasing HSF amount as evidenced by a remarkable decrease in the coefficient of thermal-linear expansion. Increasing HSF leads to stiffer materials as HSF particles act as interlock points that restrict polymer chain motion. Addition of hazelnut shell flour as filler in PLA-based green composites leads to fully biodegradable composites with balanced mechanical and thermal properties. Furthermore, it gives a solution to upgrade wastes from the hazelnut industry and contributes to lower the cost of PLA-based materials. POLYM. COMPOS., 39:848-857, 2018.

Processing and characterization of high environmental efficiency composites based on PLA and hazelnut shell flour (HSF) with biobased plasticizers derived from epoxidized linseed oil (ELO)

[EN] Different amounts of epoxidized linseed oil (ELO) have been added to poly(lactic acid)-PLA composites with hazelnut shell flour (HSF) to provide a plasticizing effect and improve the low intrinsic ductile properties of PLA/HSF composites. Mechanical, thermal, thermo-mechanical and dynamic mechanical properties have been studied in terms of the weight percentage ELO. Mechanical resistant properties in both tensile and flexural tests decrease with wt.% ELO while a remarkable increase with wt.% ELO is obtained. These results reveal a clear plasticization effect of ELO but, in addition, internal structure of PLA/HSF/ELO composites shows good PLA-HSF (matrix-particle) interactions so that indicating that ELO also provides a coupling effect between PLA matrix and HSF filler. ELO addition leads to a decrease in storage modulus (G ) obtained by dynamic mechanical thermal analysis (DMTA) in torsion mode thus giving clear evidence of the plasticization effect of ELO. Overall, the use of ELO in PLA/HSF composites is an attracting way to improve the low intrinsic fragility of these green composites; furthermore, ELO provides an improvement on thermal stability and a coupling effect between the polymer matrix and the surrounding lignocellulosic filler.This research was supported by the Ministry of Economy and Competitiveness - MINECO, Grant Number: MAT2014-59242-C2-1-R.

Sexual behavior of street children

Introduction. Street children and youth are at risk of getting engaged in different behaviors including risky sexual behavior, which adversely affects their development and health. The aim of this study was to examine sexual behavior of street children and youth, and the risks and consequences associated with sexual behavior. Material and Methods. A pilot study was conducted on a sample of 50 users of the Drop-in Centre for Street Children in Novi Sad, from 10 to 19 years of age. The study was conducted by a psychologist through structured interviews, with prior consent of the adolescent and parent. Results. Among the respondents who were sexually active, 41.2% had had the first sexual intercourse by the age of 12, their median age at that time being 14 years, while the age at the time of the first sexual intercourse is 16 years in the general population of Serbia. The majority of sexually active adolescents had several partners, one male adolescent had sex with a person of the same sex, and one was paid for sex. Very few respondents used a condom. Among 15 male sexually active respondents, three (ages 11, 12 and 14) were forced to have unwanted sexual intercourse, and a quarter of adolescents (three boys and one girl) were forced to do something unwanted during sex. Conclusion. Despite a small and unrepresentative sample, the results of this study indicate serious problems and significant risks associated with sexual behavior of children and young people who live and work in streets. This pilot study suggests that it is necessary to conduct new research on sexual behavior of street children and youth on a representative sample and with appropriate methodology. The results of a new study should be used to plan and carry out appropriate preventive measures regarding sexual behavior of street children.</jats:p

The Effect of Different Musical Tempos on Post-Exercise Recovery

An article that appeared in JASS, issue 2014Whether you choose to cruise to an electronic mix on a 5k run or head bob to classic rock in preparation for a lift on bench press, it is evident that listening to music while exercising has become a popular trend. Understanding the physiological effects created by music could reveal underlying reasons for this music-exercise integration. The purpose of this study is to determine whether fast and slow tempo music has an impact on post-exercise recovery rate. Twenty-eight healthy, 20-25 year old subjects participated by biking on a stationary bicycle until they reached a heart rate value that is twice their resting heart rate. Post-exercise recovery rate was determined based on data gathered on heart rate, breathing rate, and blood pressure for five minutes without music. This process was then repeated for each participant with the addition of either fast or slow tempo music during the post-exercise recovery time. The conclusion of this study revealed that fast tempo music caused a slower post-exercise recovery rate in terms of significant heart rate and breathing rate data. However, slow tempo music did not have a significant impact on postexercise recovery for heart rate and breathing rate. Blood pressure rate during post-exercise recovery also revealed no significance for neither slow tempo or fast tempo music
