Baugrubenböschungen mit etwas über 5 m Höhe im ungestörten Untergrund
Authors: Gödecke Jörg‐Henrik , Gödecke Heinz‐Joachim 
Published: May 2009

AbstractBei Baugrubenböschungen werden aus Platz‐ und Kostengründen die in den jeweiligen Böden möglichen Böschungsneigungswinkel ausgenutzt. Dazu gibt DIN 4124 für verschiedene Bodenarten und für bis zu 5 m hohe Baugrubenböschungen Grenzwerte für die Böschungsneigungen an, die in Regelfällen ohne weitergehende Standsicherheitsuntersuchungen nicht überschritten werden dürfen. Bei Überschreitung der Grenzwerte wie generell bei Baugrubenböschungen über 5 m Höhe sind nähere Standsicherheitsuntersuchungen nach DIN 4084 durchzuführen. Diese können zu geringeren Böschungsneigungen mit einem entsprechend erhöhten seitlichen Platzbedarf dann insbesondere führen, wenn nicht die während der Bauzeit günstigen Einflüsse ausgeschöpft werden wie die befristet ausnutzbare Kohäsion aus Feinkornanteilen und kohäsiven Verkittungen. Im Folgenden werden für Baugrubenböschungen mit etwas über 5 m Höhe für Standardfälle Grenzwerte zur Bestimmung der Böschungsneigung und des seitlichen Platzbedarfes hergeleitet. Mit zunehmender Böschungshöhe gehen die Grenzwerte gleitend in die zulässigen Böschungsneigungen über, die sich aus näheren Standsicherheitsberechnungen nach DIN 4084 ergeben. Zur rechnerischen Ermittlung der Grenzwerte wird deren Funktionsbeschreibung für allgemeine Bodenverhältnisse hergeleitet und für die häufiger auftretenden Fälle einer Baugrube in einem Kies und in einem Schluff graphisch ausgewertet.Sloped excavation walls slightly exceeding 5m height in undisturbed subsoil.For lack of space and in order to limit the costs, sloped excavation walls typically are designed by applying the maximum achievable slope angle of the soil. For different type of soil and for slope heights of up to 5 m, the German Standard DIN 4124 for this purpose provides limit values for the slope angles, which as a rule without further stability analysis should not be exceeded. Steeper inclinations exceeding these limit values as well as slope heights above 5 m then generally do require corresponding stability analysis according to DIN 4084, which could lead both to smaller slope angles and to an increased place requirement respectively, especially if favourable influences during the construction period as for example the short‐term usable cohesion‐effect resulting from a fines content and cohesive cementation would not be utilized. For standard cases in the following therefore also for slope heights slightly exceeding 5 m such appropriate limit values for determination of the maximum slope angle and the corresponding minimum place requirement will be developed. With increasing height, these limit values then will pass continuously into the admissible slope angles as resulting from related stability analysis according to DIN 4084. For the calculative determination of the limit values a mathematical function for generalized subsoil conditions will be examined and finally graphically charted for a standard situation of an excavation pit in gravel and silt.
Autobahnbrücken mit mangelhaften Schutzplanken – Zur Gefahr von Lkw‐Durchbrüchen
Authors: Gülich Hans‐A. 
Published: May 2009

AbstractSchutzeinrichtungen am Rand von Autobahnbrücken sollen Durchbruch und Absturz von Fahrzeugen verhindern. Die Zielsetzung ist ehemals durch Unfälle auf Talbrücken der Sauerlandlinie verdeutlicht und durch den folgenreichen Unfall auf der Wiehltalbrücke verschärft worden. Eine erneute Häufung von Lkw‐Durchbrüchen verweist auf unzureichende Richtlinien und untaugliche Absturzsicherungen. Das Unfallgeschehen der letzten Jahre zwingt zu Sorgfalt bei der Anwendung von Schutzeinrichtungen, Regelungen und Prüfverfahren. Nicht zuletzt auf Autobahnbrücken müssen die Randbedingungen der Verkehrssituation entsprechen.Highway bridges with inadequate guardrails – breakthroughs of trucks in sight.Safety devices at the borders of highway bridges are to prevent vehicles from breakthrough and crash. By accidents on viaducts of Sauerland‐route the objective has been demonstrated formerly and it was intensified by the momentous accident on Wiehltal viaduct in 2004. A recent amount of trucks breaking through guardrails is indicating insufficient guidelines as well as inadequate devices against plunge. The occurrence of accidents during last years forces careful application of safety devices, guidelines, and methods of testing. Not least on highway bridges conditions at the borders must correspond with the traffic situation.
Investigation of Tailoring Modifications in Pradimicin Biosynthesis
Authors: Zhan Jixun , Qiao Kangjian , Tang Yi 
Published: May 2009

AbstractDecorating pradimicin: Three tailoring enzymes in the pradimicin biosynthetic pathway have been investigated. PdmN and PdmJ were identified as a D‐amino acid ligase and a C‐5 P450 hydroxylase, respectively, whereas PdmW was deduced to be the C‐6 P450 hydroxylase.magnified image
Transradial approach for stenting of vertebrobasilar stenosis: A Feasibility Study
Authors: Patel Tejas , Shah Sanjay , Malhotra Hemant , Radadia Rajnikant , Shah Leena , Shah Sudhir 
Published: May 2009

AbstractBackground: Endovascular intervention of vertebrobasilar stenosis is a relatively new but alternative modality of management, supported by very few studies and case reports. Femoral approach has been used in all. The purpose of present study is to evaluate feasibility of the radial artery as an alternative approach for vertebral artery stenting (VAS) and basilar artery stenting (BAS). Methods: Forty‐seven patients (mean age 70 ± 5, 38 male) underwent VAS and BAS. VAS was offered in 42 and BAS was offered in five patients. All the patients were symptomatic having stenosis greater than 75%. The target vertebral artery (VA) was cannulated using a 6Fr Internal Mammary Artery (IMA) guide catheter using ipsilateral radial approach. 0.014″ floppy tip coronary guide wire was advanced and parked across the culprit stenosis. Pre dilation was done using a 2 × 12 mm2 or a 2.5 × 12 mm2 PTCA catheter and balloon mounted 2.5 × 13 mm2 or 3 × 13 mm2 bare metal stent was deployed using 8–10 atm pressure for all chronic lesions. For acute occlusions, the procedure was divided in two stages. In first stage, the lesion was dilated using PTCA catheter (1.5 × 12 mm2) at 4–6 atm pressure just to establish the distal flow. After 24 hr, the patient was brought back and the culprit lesion was stented using 8–10 atm pressure. The procedure was staged to prevent hyperperfusion brain injury. Results: VAS was successful in 42/42 (100%) patients. BAS was successful in five out of five (100%) patients. However, three patients had transient periprocedural stroke which recovered completely within 6 hr and one patient developed intracerebral hemorrhage (ICH) who died after 24 hr. Hyper perfusion brain injury was the cause for ICH. Conclusion: VAS and BAS using the transradial approach appear to be safe, technically feasible, and reproducible. Technical ease of cannulation of vertebral artery with IMA guide catheter using ipsilateral transradial approach should make it more convenient when compared with femoral approach.© 2009 Wiley‐Liss, Inc.
