Cabinets in Eastern Europe
No full text'Cabinets in Eastern Europe' is a comprehensive study which enables the reader to compare the origins, structure, composition and activities of these cabinets and to draw lessons from this comparison. Each chapter begins with a survey of the evolution of cabinets since the fall of communism at the beginning of the 1990s. The emphasis is then laid on the place of the cabinet in the constitution and on the role of presidents and prime ministers in the formation of life of each cabinet. At a time when most Eastern European countries are candidates for membership in the European Union, this volume provides a comparative presentation of the way in which cabinets have been evolving in Eastern Europe since the end of communism.Cabinets in post-communist East-Central Europe and in the Balkans : introduction / Jean Blondel. -- Part 1.

Rommel the end of a Legend
No full textProduct Description: Field Marshal Erwin Rommel was the most popular soldier of World War II. Under his leadership the German Africa Corps advanced all the way to Egypt. Known as the 'Desert Fox', Rommel was considered invincible. That is the story told in the history books. Ralf Georg Reuth paints a different portrait of Erwin Rommel: a picture of a man, who owed his fame in part to the Nazi propaganda and whose role in the resistance is still unclear. Reuth shows us the image of a soldier who was promoted by Hitler and who continued to stay true to him until the end, when he committed suicide at the behest of his Fuhrer. His personal fate is the mirror image of the German tragedy of that time: 'to have followed the Fuhrer to the end and to believe that one had thereby done one's patriotic duty.
Data: Leaching Potential of Heavy Metals from Road-deposited Sediment and Sorptive Media during Dry Periods in Storm Water Quality Improvement Devices
No full textThis dataset contains results of experiments studying the leaching potential of heavy metals from road-deposited sediment (RDS) and three sorptive media (granular activated lignite, granular ferric hydroxide and zeolite) used in storm water quality improvement devices (SQIDs) to retain heavy metals from road runoff. The contaminated RDS and pre-stressed sorptive media were exposed in quiescent batch leaching tests to three different synthetic road runoffs (SRR, SRR+NaCl, SRR+DOM), thereby the effects of de-icing salts and dissolved organic matter were assessed. Samples were withdrawn after (4), 24, 48 and 168 h. The exerted methods are described comprehensively in the associated publication. This dataset contains following items:1. Metal contents of road-deposited sediment and three pre-stressed sorptive media used in SQIDs2.

"Development and optimization of bibenzimidazole transition metal chromophores for luminescent ion sensing and photocatalysis"
No full textThe recognition and fixation of highly reactive systems by binding within defined spatial geometries is a fundamental principle of the enlivened nature. In the last four decades this biologically tenet was transferred to artificial systems and the yet emergent area of supramolecular chemistry developed to a driving force. The latter defined itself “over and above the molecule”, that is the chemistry of tailored intermolecular interactions. Thereby, not only the interplay of molecules, but also that of characteristic molecule entities – with its inherent features – is defined as “supramolecular”.[1,2]
The stunning development of this research area is inseparably related to the increasing knowledge of preparative methods for the synthesis and characterization of complex host-guest structures.[3] Accessible and comprehensively investigated supramolecular host-compounds of today range from “classic” crown ethers[4] over calixarenes[5] and imines[6–11] to photosensible hosts.[1,12,13] The mentioned compound classes bear a receptor function for second-sphere interaction with substrates, and hence enable the selective coordination of anionic, cationic and neutral guests. These features provide the basis for the development of the research area of artificial molecular recognition.
Especially, transition metal chromophores based on polypyridyl ruthenium(II), osmium(II) or iridium(III) complexes have become fundamental building blocks in numerous molecular optical sensors.[14–18] This is mainly due to the outstanding photophysical properties, i.e. broad light absorption and emission features across the visible regime of the light spectrum. Furthermore, the complexes are featured with long-lived triplet metal-to-ligand charge transfer (3MLCT) states.[14,19–27]
The focal point of this work was the synthesis and characterization of luminescent complex compounds for the usage as supramolecular sensors and for application in the heterogeneous light-induced water reduction. Along these lines, the principal chromophore scaffolds investigated in this thesis are primarily derivatives of bis(2-phenylpyridine) iridium(III) α-diimine and in the second instance bis(2,2’-bipyridine) ruthenium(II) α-diimine.
In the first part of the thesis the iridium(III) model complex of 5,5’,6,6’-tetramethyl-2,2’-bibenzimidazole and its homodinuclear complex bearing a simple unsubstituted bibenzimidazole motif are introduced. The structure-property relations of the iridium(III) bibenzimidazole complex are discussed and compared to related ruthenium(II) complexes. Especially the acid-base chemistry is outstanding with a strongly luminescent character in all protonation states of the complex. This feature is of pivotal importance for this and further studies, as it could provide a spectroscopic tool for direct observation of proton release of these molecules.
Inspired by the special features of the iridium(III) model complex, the interaction of the latter with basic anions was investigated. Hydrogen bond donor features of the iridium(III) complex were experimentally verified and implications for luminescent sensing could be drawn.
In a second step the present supramolecular sensor strategy was optimized using the intermolecular quencher 3,5-dinitrobenzoate (DNBA). Strong H-bond supported ion pair bonding with the electron accepting dinitro-benzoate anion switches the luminescence “off”. The luminescence of the sensor system is switched back “on” when benzoate is replaced by competing H-bonded small anions, therefore leading to enhanced sensitivity of the sensor system. Additionally, to the best of my knowledge, the presented system exceeds all ruthenium(II) biimidazole-type sensors known in literature so far, regarding an increase in luminescence intensity of e.g. 450 % for chloride and as the change in the luminescence intensity can easily be followed with the naked eye.
For ruthenium(II) complexes, pioneering work was performed by Ye and co-workers who presented a number of Ru(II) imidazole-like complexes acting as promising anion sensors, however limited by small selectivity and sensitivity. In order to improve the literature known ruthenium(II) based sensors, sterically demanding substituents were introduced in the ligand framework of the bibenzimidazole. Thereby, the secondary binding site of the complexes are spatially confined which leads to a functional dimming of the emission intensity. Subsequently, the recognition properties towards small anions of the complexes could be directed selectively, accompanied by a significant enhancement in luminescence sensitivity.
In a conclusive project, the heterodinuclear bibenzimidazole bridged iridium(III)/ ruthenium(II) complex Ir-BBI-Ru was synthesized to investigate the synergy effects of the sole chromophore units tested before.
The comprehensive investigation of the basic properties of the complex and its applicability as photosensitizer in the light-induced hydrogen production are presented
DEUTSCHE AFRIKA KORPS: Peranan Field Marshal Erwin Rommel dalam Perang Dunia II di Afrika Utara 1941-1943
No full textLatar belakang penelitian ini dikarenakan ketertarikan penulis akan suasana Perang Dunia II di Afrika Utara yang mempunyai ciri khas tersendiri dibanding pertempuran lainnya yang terjadi selama Perang Dunia II berlangsung. Masalah utama yang dibahas dalam skripsi ini adalah ‘bagaimana peranan Field Marshal Erwin Rommel dalam Perang Dunia II di Afrika Utara?’. Masalah utama ini kemudian dijabarkan kedalam beberapa pernyataan penelitian, yakni (1) bagaimana latar belakang keterlibatan Jerman dalam pertempuran di Afrika Utara 1941-1943?, (2) apa yang melatarbelakangi Jerman menunjuk Field Marshal Erwin Rommel untuk memimpin Deutsche Afrika Korps?, (3) bagaimana proses pertempuran yang dipimpin Field Marshal Erwin Rommel di Afrika Utara 1941-943?, (4) Bagaimana akhir dari pertempuran Jerman pada Perang Dunia II di Afrika Utara 1941-1943? Metode yang digunakan adalah metode historis meliputi pengumpulan sumber, kritik sumber, interpretasi dan historiografi. Untuk memperdalam analisis, peneliti menggunakan pendekatan interdisipliner melalui kajian ilmu sosiologi, militer dan politik dengan menggunakan konsep-konsep seperti peran, status, perang, serta menggunakan teori konflik Lewis A. Coser dan teori geopolitik Karl Haushoffer. Deutsche Afrika Korps dibentuk akibat keterlibatan Jerman dalam pertempuran di Afrika Utara. Keterlibatan Jerman di Afrika Utara disebabkan karena Afrika Utara memiliki arti penting bagi Jerman karena memiliki Terusan Suez dan benteng Gibraltar. Selain itu hubungan Italia-Jerman yang merupakan blok Poros akibat perjanjian Pakta Baja dan Pakta Tripartit membuat Jerman harus terlibat dalam pertempuran. Deutsche Afrika Korps ini dipimpin oleh Field Marshal Erwin Rommel yang dipercayai oleh Hitler karena kepimpinannya dan kepopulerannya dikalangan pasukan Jerman. Rommel memiliki peranan yang sangat penting ketika Jerman membantu Italia di Afrika Utara. Taktik dan strategi Rommel yang jenius membuat Sekutu kewalahan. Strategi yang digunakan diantaranya membuat tank dari kayu untuk mengelabui musuh dan juga memposisikan Flak 88mm dalam bentuk U untuk menjebak tank musuh dalam jebakannya. Proses pertempuran di Afrika Utara ini diawali ketika Rommel mendarat di Tripoli dengan langsung melakukan ofensif mendesak Sekutu menuju perbatasan Libya-Mesir. Selain itu juga Rommel mendapatkan perlawanan dari Sekutu yang melakukan beberapa operasi yang bertujuan untuk memukul mundur Jerman dari Afrika Utara. Operasi tersebut diantaranya operasi Brevity, operasi Battleaxe dan operasi Crusader. Perlawanan Rommel berakhir ketika kekalahan Jerman di El Alamein yang disebabkan faktor kurangnya logistik dan ketidakseimbangan kuantitas pasukan yang dimiliki antara Poros dan Sekutu di El Alamein. Kekalahan Jerman di El Alamein merupakan salah satu turning point bagi Sekutu dalam Perang Dunia II ini dan mengubah arah berlangsungnya perang kedepannya.
The reason of research because author interested with World War II situation in Northern Africa that have characterized be compared another war in World War II. The main problem to discuss in this research is “ How Field Marshal Erwin Rommel role in the World War II in Northern Africa?”. The main problem divided into four research questions, (1) what the purpose Germany includes in battle of Northern Africa 1941-1943?, (2) what the reason Germany choose Field Marshal Erwin Rommel to led Deutsche Afrika Korps?, (3) what is the process that led Field Marshal Erwin Rommel in Northern Africa 1941-1943?, (4) how to end the Germany battle in the World War II in Northern Afrika 1941-1943?. The research uses historic methodology involved Heuristics, source criticism, interpretation, and historiography. To deepen the analysis, researcher uses interdisciplinary approach through the study sociology, military, and politics with concept and theory like role, status, war, conflict theory from Lewis A. Coser, and geopolitical theory from Karl Haushoffer. Deutsche Afrika Korps formed as result of Germany includes in Battle of Northern Africa. Germany involvement in Northern Africa due to Northern Africa has significance for Germany because have Suez Canal and Fort Gibraltar. In addtion, the relation between Germany and Italy who where Axis due to Agreement Steel Pact and Tripartit Pact makes Germany must includes in the battle. Deutsche Afrika Korps is led by Field Marshal Erwin Rommel and believed Hitler because leadership and popularity among the Germany Troops. Rommel has a very important role when Germany helped Italy in Northern Africa. Tactics and strategy genius Rommel make allied overwhelmed. The strategy used them made of wood tanks to trick enemy and Flak 88m in form U to trap enemy tanks. The process battle in Northern Africa begins when Rommel landed in Tripoli and makes offensive to push Allied towards Libya-Egypt border. It also Rommel get resistance from Allied who perform several operations aimed at repelling Germany of Northern Africa. Such operations include Brevity Operation, Battleaxe Operation, and Crusader Operation. Rommel resistance ended when Germany defeat in El Alamein due to lack of logistical factors and troops possessed imbalance quantity between Axis and Allied. The defeat of Germany in El Alamein is one of turning point for Allied in World War and changing the direction of war in the future
“Honorable men”: Robert E. Lee, Erwin Rommel, and the Memory and Forgetting of Defeat and Guilt
No full textIn October 2017, White House Chief of Staff John F. Kelly criticized those who wanted to bring down statues of Confederate General Robert E. Lee, defending him as “an honorable man.” Geraldo Rivera also took part in the heated debate about Confederate monuments: “#RobertELee is a lot like #ErwinRommel a glorious yet failed warrior, untarnished by the sins of his brothers.” With his tweet the Fox News commentator and former talk show host responded to a Twitter post by the economist and columnist Paul Krugman who had asked: “On statues of Robert E. Lee: what would we think if German towns put up statues of Erwin Rommel, also a good general serving a vile cause?” This article looks at the larger debate about the Lost Cause and the history and memory of slavery and the Civil War in a case study focusing on Robert E. Lee, trying to raise some larger questions of memory and forgetting through a comparison with Erwin Rommel. The article analyzes the special places Southern General Robert E. Lee and Feldmarschall Erwin Rommel have occupied in the memories of the American Civil War and World War II, respectively. It will argue that to find something honorable in all the evil of lost wars that were fought for the wrong ends can be regarded as an individual and collective way to deal with pain, guilt, and defeat. Part of this is honoring the soldiers and their sacrifices, focus on famous battles, and celebrate distinguished generals while ignoring and “forgetting” what the real goals of these wars had been. Today, both Rommel and Lee have been pushed off their pedestals, in the case of Lee statues even literally. But the fact that Lee and Rommel have been glorified as honorable, loyal, and patriotic military men also by those who were their opponents/enemies makes this comparison even more interesting, because it cannot be explained by a collective amnesia in order to suppress and forget guilt and crimes. In connection with remembering, the author argues, it is also important to take a closer look at the different functions of “forgetting” that have been described by Aleida Assmann and other scholars, especially at what Assmann calls “complicit” and “constructive” forms of forgetting. Both examples show that these types of forgetting protected perpetrators, helped shape a selective historical narrative, and were also important in new beginnings and reconstruction after a catastrophic defeat

Pseudomonas aeruginosa Type IV pilus and resistance to the antimicrobial properties of surfactant protein-A
No full textThe lung contains numerous innate immune cells and effector proteins. One important component of this immune system is the surfactant protein-A (SP-A), which facilitates microbial clearance by opsonization and membrane permeabilization. Pseudomonas aeruginosa (PA) is a major Gram-negative bacterial pathogen commonly associated with chronic lung infection in cystic fibrosis. In order to resist the antibacterial effects of SP-A, PA expresses various structural and secreted virulence factors. Previously, Wu et al (2003) have shown that Escherichia coli lipopolysaccharides (LPS) are important in resisting SP-A-mediated membrane permeabilization. Zhang et al (2005) performed a comparative signature-tagged mutagenesis screen to identify PA virulence factors needed to resist SP-A-mediated lung clearance, and identified PchA (isochorismate synthase) and PtsP (phosphoenolpyruvate protein phosphotransferase) as important for resisting SP-A-mediated membrane permeability. Zhang et al (2007) further showed that PA flagellum is important for resisting SP-A-mediated membrane permeabilization. Finally, Kuang et al (2011) have shown PA elastase degrades SP-A, allowing an avenue for PA to escape SP-A-mediated opsonization and membrane permeabilization.
In this study, we demonstrated that type IV pilus (Tfp) is important in the resistance of lung clearance both in the presence and absence of SP-A. The Tfp-deficient mutant, ΔpilA, is severely attenuated in an acute pneumonia model of infection in the lungs of wild-type mice that it allows similar bacterial load as PAO1 in the lungs of SP-A-/- mice. The ΔpilA bacteria are more susceptible to SP-A-mediated aggregation and opsonization. In addition, the integrity of the outer membranes of ΔpilA bacteria is compromised, rendering them more susceptible to SP-A-mediated membrane permeabilization. By using Tfp extension and retraction mutants, we demonstrate that the increased susceptibility of ΔpilA to SP-A-mediated opsonization is caused by the total absence of Tfp from PA cells. Finally, we provide evidence that increased expression of an 18 kDa nonpilus adhesin OprH in ΔpilA, may explain why there is an increased susceptibility to SP-A-mediated phagocytosis.
In addition, we also have shown that Tfp glycosylation with O-antigen subunits allows for increased resistance to SP-A. We have also shown the glycosyltransferase mutant, 1244G7, which is deficient in O-antigen, is more susceptible to SP-A-mediated lung clearance and phagocytosis, but not membrane permeability. Finally, we have shown that the increase susceptibility of 1244G7 is associated with exposure of putative mannose residues.Item withdrawn by Mark Zulauf ([email protected]) on 2013-09-23T20:00:12Z
