People with type 2 Diabetes have an elevated risk for developing cardiovascular disease (CVD) for which dyslipidemia is the major contributor. Diabetic patients have characteristic pattern of dyslipidemia with decreased level of high density lipoprotein cholesterol (HDL-C) and elevated triglycerides (TG) level. However, in diabetes mellitus, low density lipoprotein cholesterol (LDL-C) which is used as one of the markers for the risk of CVD, is underestimated so in such cases the levels of non-High density lipoprotein cholesterol (non-HDL-C) can be a stronger predictor of CVD as it strongly correlates with atherogenic lipoproteins. Therefore, an attempt has been made to evaluate the level of non-HDL-C as a newer marker for the risk of cardiovascular disease and to fi nd out the pattern of dyslipidemia in diabetes mellitus. The present study comprised of 82 type 2 Diabetic cases and 81 non-diabetic controls. Among the diabetics, the majority of the subjects (61.0%) were HDL-C dyslipidemic. However, among the controls, the maximum numbers of individuals (40.7%) were TG dyslipidemic. Diabetics have signifi cantly elevated ratio of total cholesterol to high density lipoprotein cholesterol (TC/HDL-C) and the signifi cant increased levels of non-high density lipoprotein cholesterol (non-HDL-C) compared to controls which can be used as markers of dyslipidemia and can also be used to predict the risk of cardiovascular disease in type 2 Diabetes Mellitus.
Development and Validation of a Rapid and Reliable Method for TPMT Genotyping using real-time PCR
(2012)
Education is widely seen as an important means of addressing both national and international problems, such as political or religious extremism, poverty, and hunger. However, if developing countries are to become societies that can compete properly with Western industrialized countries, not only is a fundamental shift in thinking with regard to the value of education and more/better provision of teaching required, but strong support from other countries is needed as well. This article explores questions such as whether Western policymakers can avoid a repetition of some of the failures of the past few decades in terms of providing foreign aid; how educators and providers of educational scenarios and learning contents can foster and manage the creation of a worldwide knowledge society; and in particular, if the provision of open educational resources (OER) can realistically overcome the educational gap and foster educational justice.
Malware is responsible for massive economic damage. Being the preferred tool for digital crime, botnets are becoming increasingly sophisticated, using more and more resilient, distributed infrastructures based on peer-to-peer (P2P) protocols. On the other side, current investigation techniques for malware and botnets on a technical level are time-consuming and highly complex. Fraunhofer FKIE is addressing this problem, researching new ways of intelligent process automation and information management for malware analysis in order to minimize the time needed to investigate these threats.
Today’s computer systems face a vast array of severe threats that are posed by automated attacks performed by malicious software as well as manual attacks by individual humans. These attacks not only differ in their technical implementation but may also be location-dependent. Consequentially, it is necessary to join the information from heterogeneous and distributed attack sensors in order to acquire comprehensive information on current ongoing cyber attacks.
Handlungsspielräume zur Gestaltung nachhaltiger Mobilität werden unzulänglich genutzt. Wissenschaftliche Erkenntnisse aus Gesundheit, Umwelt und Verkehr finden zögerlich Eingang in Verkehrspolitik. Konkurrenz der Ministerien für Wirtschaft, Verkehr, Umwelt und Gesundheit hindert an der Wahrnehmung der Wertschöpfung nachhaltiger Mobilität. Bemühungen um eine Entlastung der Innenstädte sind von effizienter Prävention weit entfernt, externe Kosten werden ignoriert. Biokraftstoffpflanzungen (mit Raubbau an Regenwäldern) erhöhen die Emissionen der industrialisierten Landwirtschaft und ruinieren Wasserressourcen. Diese Verschiebung in andere klimagasrelevante Produktionsbereiche verschlimmert die globalen CO2-Bilanzen. Wenige Einzelfälle sind verkehrs-ökologisch am Verursacherprinzip orientiert (z. B. in Österreich). Die WHO stellt Wissen bereit, unerwünschte Effekte vermeidbar zu machen. Über vermeidbare Gesundheitsfolgekosten (Atemwegserkrankungen, Übergewicht) liegt zwar genügend Material vor. Transdisziplinäre Betrachtungen der Wertschöpfung werden aber als nicht umsetzbar abqualifiziert.
Auf dem Weg zur Promotion: Zur Benachteiligung von Fachhochschul-Absolventinnen und -Absolventen
(2012)
Das Team aus Sascha Czornohus, Katrin Dobersalske, Fabian Heuel und Nina Petrow bearbeitet mit seinem „Aufsatz Auf dem Weg zur Promotion: Strukturelle Benachteiligung von Fachhochschul-Absolventinnen und -Absolventen“ ein hochschulpolitisch brisantes und daher sensibles Thema, das die Hochschulpolitik inzwischen in offener Auseinandersetzung beschäftigt. Seit die Forschung unstreitig zu den Aufgaben der Fachhochschulen zählt, Promotion zu den Berufungsvoraussetzungen an ihnen gehört und alle Professoren an Universitäten ausgebildet wurden, wurde die Forderung nach Promotionszugängen für die Master-Absolventen der Fachhochschulen immer lauter. Teillösungen wurden gefunden, aber die Debatte wird breiter und umfasst inzwischen (auf dem Hintergrund der Profil- und Schwerpunktbildung mit sehr unterschiedlichem Ausbau der Fächer) die Frage, ob überhaupt ganzen Hochschulen das Promotionsrecht verliehen werden sollte oder von Fachbereich zu Fachbereich verschieden – auch bei Universitäten. Die Überzeugung, dass die Verteilung des Promotionsrechts in Deutschland überprüft werden sollte, breitet sich aus. Das HSW ist an der breiteren Diskussion dieses Themas interessiert.
The criteria for assessing the quality of rubber materials are the polymer or copolymer composition and the additives. These additives include plasticizers, extender oils, carbon black, inorganic fillers, antioxidants, heat and light stabilizers, processing aids, cross-linking agents, accelerators, retarders, adhesives, pigments, smoke and flame retardants, and others. Determination of additives in polymers or copolymers generally requires the extraction of these substances from the matrix as a first step, which can be challenging, and the subsequent analysis of the extracted additives by gas chromatography (GC), GC–mass spectrometry (MS), high performance liquid chromatography (HPLC), HPLC–MS, capillary electrophoresis, thin-layer chromatography, and other analytical techniques. In the present work, nitrile rubber materials were studied using direct analytical flash pyrolysis hyphenated to GC and electrospray ionization MS in both scan and selected ion monitoring modes to demonstrate that this technique is a good tool to identify the organic additives in nitrile rubber.
In a research project funded by the German Research Foundation, meteorologists, data publication experts, and computer scientists optimised the publication process of meteorological data and developed software that supports metadata review. The project group placed particular emphasis on scientific and technical quality assurance of primary data and metadata. At the end, the software automatically registers a Digital Object Identifier at DataCite. The software has been successfully integrated into the infrastructure of the World Data Center for Climate, but a key was to make the results applicable to data publication processes in other sciences as well.
Jede Führungskraft hat ein bestimmtes Menschenbild, das ihre Arbeit und den Umgang mit den Mitarbeitern prägt. Diese Menschenbilder sind auch einem historischen Wandel unterworfen. Denn im Lauf der Jahrzehnte haben sich unsere Vorstellungen vom Menschen als Mitarbeiter grundlegend gewandelt. Welche Konsequenzen dieser Wandel für die Mitarbeiterführung hat, untersucht der folgende Artikel.
The relative contributions of radial and laminar optic flow to the perception of linear self-motion
(2012)
When illusory self-motion is induced in a stationary observer by optic flow, the perceived distance traveled is generally overestimated relative to the distance of a remembered target (Redlick, Harris, & Jenkin, 2001): subjects feel they have gone further than the simulated distance and indicate that they have arrived at a target's previously seen location too early. In this article we assess how the radial and laminar components of translational optic flow contribute to the perceived distance traveled. Subjects monocularly viewed a target presented in a virtual hallway wallpapered with stripes that periodically changed color to prevent tracking. The target was then extinguished and the visible area of the hallway shrunk to an oval region 40° (h) × 24° (v). Subjects either continued to look centrally or shifted their gaze eccentrically, thus varying the relative amounts of radial and laminar flow visible. They were then presented with visual motion compatible with moving down the hallway toward the target and pressed a button when they perceived that they had reached the target's remembered position. Data were modeled by the output of a leaky spatial integrator (Lappe, Jenkin, & Harris, 2007). The sensory gain varied systematically with viewing eccentricity while the leak constant was independent of viewing eccentricity. Results were modeled as the linear sum of separate mechanisms sensitive to radial and laminar optic flow. Results are compatible with independent channels for processing the radial and laminar flow components of optic flow that add linearly to produce large but predictable errors in perceived distance traveled.
