Abstract:

Corruption, as a nontraditional form of crime, occurred when power is abused to gain certain favours for individuals or parties at the expense of the rest. Siemens Aktiengesellscahft (Siemens AG) bribery case is the biggest company corruption revealed in history, in which the company had been convicted guilty for giving bribes to governments in many countries, from developing to developed countries. In Iraq, Siemens AG was proved guilty for giving bribes to Saddam Hussein regime during its involvement in United Nation Oil for Food Programme (UN-OFFP) in 2000-2002. This research is conducted to understand causing factors of such action by employing qualitative data for further analysis. Research finding shows that corruption in UN-OFFP involving three institutions: Siemens AS, Saddam Hussein regime, and UN, was occurred due to pragmatism in pursuing economic motive which encouraged by accommodative culture and enabled by weak law enforcement.

Abstract:

This case describes how Siemens Power Corporation, a Richland, Washington, USA-based manufacturer of nuclear fuel assemblies, came to adopt and implement SAP's R/3 application suite, the world's leading enterprise resource planning (ERP) package. The case introduces the reader to the type of decision making related to an ERP adoption and implementation and provides some interesting examples of factors which may influence actual decisions and outcomes. Among other things, the case touches on the following issues: the relationship between restructuring (re-engineering) and software adoption and implementation, the choice of package software, the pros and cons of alternative implementation approaches (‘big bang’ versus ‘phased'), the selection of hardware and the value of consultants. By January 1999 Siemens Power Corporation's (SPC's) restructuring project was more than 2 years under way. To SPC's top management's great relief, the company had made major progress ever since SPC's German parent Siemens AG hired a consulting team to help SPC get back on its path towards profitability. In particular, the largest and riskiest of its individual restructuring subprojects – SPC's SAP R/3 implementation – seemed on the way to becoming a success.

Abstract:

Abstract BACKGROUND: Fully equipped high-end digital subtraction angiography (DSA) within the operating room (OR) environment has emerged as a new trend in the fields of neurosurgery and vascular surgery. OBJECTIVE: To describe initial clinical experience with a robotic DSA system in the hybrid OR. METHODS: A newly designed robotic DSA system (Artis zeego; Siemens AG, Forchheim, Germany) was installed in the hybrid OR. The system consists of a multiaxis robotic C arm and surgical OR table. In addition to conventional neuroendovascular procedures, the system was used as an intraoperative imaging tool for various neurosurgical procedures such as aneurysm clipping and spine instrumentation. RESULTS: Five hundred one neurosurgical procedures were successfully conducted in the hybrid OR with the robotic DSA. During surgical procedures such as aneurysm clipping and arteriovenous fistula treatment, intraoperative 2-/3-dimensional angiography and C-arm-based computed tomographic images (DynaCT) were easily performed without moving the OR table. Newly developed virtual navigation software (syngo iGuide; Siemens AG) can be used in frameless navigation and in access to deep-seated intracranial lesions or needle placement. CONCLUSION: This newly developed robotic DSA system provides safe and precise treatment in the fields of endovascular treatment and neurosurgery.

Abstract:

Abstract. Ziel dieses Beitrages ist es, den Entwicklungspfad Paderborns vom Zentrum eines ländlichen Wirtschaftsraums zum IT-Cluster zu analysieren. Dieser Entwicklungspfad wurde massgeblich von der Nixdorf AG bestimmt, die sich in den 1970er und 1980er Jahren zum grössten Arbeitgeber und fokalen Unternehmen Paderborns entwickelte. Dabei gestaltete das Unternehmen aktiv das institutionelle Umfeld seines Standorts, etwa durch die Finanzierung von Forschungs- und Bildungseinrichtungen. Im Jahr 1989 kam es nach der Übernahme der Nixdorf AG durch die Siemens AG zu einschneidenden Veränderungen für den Wirtschaftsstandort Paderborn: Unternehmensbereiche wurden verkleinert oder geschlossen, mehrere Tausend Arbeitsplätze gingen verloren.Trotzdem kam es nicht zum Bruch mit dem bisherigen Entwicklungspfad, da zur gleichen Zeit eine Vielzahl von IT-Unternehmen gegründet wurde. Die Ergebnisse einer Befragung von 103 IT-Unternehmen deuten darauf hin, dass die durch die Nixdorf AG gestalteten institutionellen Rahmenbedingungen und vor allem der IT-Schwerpunkt der Universität die Gründung der neuen Unternehmen förderten, während die direkte Bedeutung von Ausgründungen aus der Nixdorf AG gering war.

Abstract:

Contemporary discussions in the comparative political economy of innovation revolve specifically around the question of globalization's impact on the observable diversity of innovation patterns, institutionally grounded comparative advantages of firms and countries as well as their evolution over time. The paper develops the concept of “contingent institutional adaptation” to trace institutional evolution at the firm level. It advances the idea that contingent adaptation can cause institutional hybridization, an evolutionary path defined by change and continuity, thereby offering a more nuanced concept of institutional evolution over time. In a historic single-case study the paper investigates the German Siemens AG and its efforts to remain on the cutting-edge of major information and communication technologies in two time periods (1847–1914; 1989–2013), both marked by institutional adaptations resulting in hybridization. Ultimately, institutional hybridization led to Siemens’ retreat from all information and communication technology sectors.

Abstract:

Legal proceedings against Siemens AG arising from allegations of bribery were concluded on 15 December 2008 in Munich, Germany, as well as in Washington, DC. The Siemens case has been the largest of its kind. It has changed the compliance landscape and has brought criminal law out of its dark corner and to the attention of the corporate community. Board directors and other managers have painfully become aware that noncompliance with criminal law may not only threaten the existence of a company, but also may lead directly to personal criminal liability. The subject of compliance has also raised the attention of legal advisors and accountants that naturally must recommend the “best standard,” especially if the sensitive subject of corruption is concerned. Last but not least, prosecutors now have a deeper inside knowledge of corruption structures than ever before. Thus, compliance standards tend to rise expeditiously even without regulators taking any action. Siemens thereby smartly has lifted compliance to the “cornerstone” of its business and generally - in particular when it comes to anti-corruption programs -presents its improved and expanded compliance organization as a leading example.

Abstract:

Abstract Para-aortic malignant lymphoma invading the thoracic aorta can cause aortic rupture. Thoracic endovascular aortic repair (TEVAR) is a good option to treat aortic rupture associated with para-aortic malignancies. It is essential to detect the exact tumour location during TEVAR; however, it is often difficult to confirm the location with conventional 2-dimensional fluoroscopic or angiographic images. We describe successful TEVAR using syngo DynaCT (Siemens AG, Forchheim, Germany) in a 64-year-old man with para-aortic malignant lymphoma invading the descending aorta.

Abstract:

HIV prevalence in Oman is low (<5 %); however, 45 % of the population are expatriates, including a portion originating from countries with high HIV prevalence (>5 %). HIV screening is performed at regional public health laboratories as part of a medical fitness programme for residency applicants. We conducted a retrospective evaluation of indeterminate serology results from 11 females of African origin, aged 21–43 years. Serology testing for HIV was conducted according to the national Oman algorithm: fourth-generation immunoassays (Bio-Rad GS HIV Combo Ag/Ab EIA, Siemens Enzygnost HIV Integral 4, Abbott ARCHITECT HIV Ag/Ab Combo, Roche Elecsys HIV Combi PT, bioMérieux VIDAS HIV DUO QUICK), confirmatory assays (Geenius HIV 1/2 Confirmatory, INNO-LIA HIV I/II Score) and PCR testing. Confirmatory testing to resolve indeterminate results was conducted with available samples for five patients using a combination of immunoassays, confirmatory assays, PCR/PERT and pro-viral DNA levels, at three external laboratories; Roche Diagnostics (Germany), Swiss National Laboratory (Switzerland) and Barts Health NHS Trust (UK). Nineteen serum, 15 plasma and two whole-blood samples were analysed. Nine of ten patients analysed on Bio-Rad and Siemens immunoassays were highly reactive; seven were highly reactive on the Abbott assay. Eight of nine patients tested with the Roche assay were negative. Three of four patients tested on the bioMérieux assay were negative. Five patients underwent confirmatory testing at external laboratories; all were negative by HIV-RNA or pro-viral DNA testing. In conclusion, HIV-RNA and pro-viral DNA testing is recommended for HIV screening of individuals from high-prevalence regions coming to low-prevalence regions.

Abstract:

A feasibility trial was carried out in four European centers to test the safety and efficacy of stabilized insulin (HOE 21GH) in twenty remote-controlled infusion pumps (Siemens AG) implanted in twenty type I diabetic patients. Fifteen had been implanted with intraperitoneal and five with the intravenous access route. Total observation time was 18.2 patient years. A total of 36,077 self blood glucose measurements were collected from the patients. Of these 62.9% were in the acceptable range of 70–160 mg/dl. Symptomatic hypoglycemias were rare and reported in a frequency of 2.6 per patient months; of these 0.22 per patient year required medical attention. The median of HbA1c was in the upper normal range or slightly above. Three pumps had to be explanted prematurely because of surgical and technical problems. Although some technical and clinical problems were still observed, the study shows the successful clinical use of implanted, remote-controlled dosing devices and the special insulin preparation stabilized with polyethylene-polypropylene-glycol (Hoechst AG).

DOI: 10.17323/1811-038X-2018-27-4-129-140 Corruption has been broadly discussed in the academic literature for several decades, yet there are few studies dedicated to addressing this topic in the classroom. This paper aims to fill this research gap by providing an example of a seminar on corruption and informal practices in Russia, given for international students at one Western European university. The aim of the seminar was to study the phenomenon of corruption from different perspectives, using different teaching techniques and materials, in order to encourage students to conduct their own analyses and reflections on real-life situations. Drawing on the structure of the seminar, this article provides a brief overview of the historical perspective of corruption in Russia, then summarizes the approach and teaching methods used in the seminar, including presentations, group work, discussions and homework. Finally, the authors provide a detailed overview of the learning materials used. They conclude that an interdisciplinary approach involving numerous literary works, films and case studies is particularly suitable for understanding the concept of “corruption” and “informality” in their respective cultural contexts and for preparing students to face this issue in their (future) professional lives.

Abstract:

When medically intractable epilepsy is multifocal or focal but poorly localized, neuromodulation can be useful therapy. One such technique is deep brain stimulation (DBS) targeting the anterior nucleus of the thalamus (ANT). Unfortunately, the ANT is difficult to visualize in standard MRI sequences and its indirect targeting is difficult because of thalamic variability and atrophy in patients with epilepsy. The following study describes the novel use of the fast gray matter acquisition T1 inversion recovery (FGATIR) MRI sequence to delineate the mammillothalamic tract for direct targeting of the ANT through visualizing the termination of the mammillothalamic tract in the ANT.The day prior to surgery in a 19-year-old, right-handed woman with a 5-year history of epilepsy, MRI was performed on a 3-T Siemens Prisma scanner (Siemens AG, Healthcare Sector) using a 64-channel head and neck coil. As part of the imaging protocol, noncontrast magnetization-prepared rapid gradient echo (MP-RAGE) and diffusion tensor imaging (DTI) sequences were obtained for targeting purposes. The ANT was directly targeted using the FGATIR sequence, and bilateral Medtronic 3389 leads were placed. At the last follow-up (2 months), the patient reported an approximate 75% decrease in seizure frequency, as well as a decrease in seizure severity.

Abstract:

Three-dimensional finite element analysis is one of the best ways to assess stress and strain distributions in complex bone structures. However, accuracy in the results may be achieved only when accurate input information is given. A semi-automated method to generate a finite element (FE) model using data retrieved from computed tomography (CT) was developed. Due to its complex and irregular shape, the glenoid part of a left embalmed scapula bone was chosen as working material. CT data were retrieved using a standard clinical CT scanner (Siemens Somatom Plus 2, Siemens AG, Germany). This was done to produce a method that could later be utilized to generate a patient-specific FE model. Different methods of converting Hounsfield unit (HU) values to apparent densities and subsequently to Young's moduli were tested. All the models obtained were loaded using three-dimensional loading conditions taken from literature, corresponding to an arm abduction of 90°. Additional models with different amounts of elements were generated to verify convergence. Direct comparison between the models showed that the best method to convert HU values directly to apparent densities was to use different equations for cancellous and cortical bone. In this study, a reliable method of determining both geometrical data and bone properties from patient CT scans for the semi-automated generation of an FE model is presented.

Abstract:

This article reviews the copper cables in Detroit Edison’s Frisbie Station to be retrofit in mid-2000 with high-temperature superconductor (HTS) cables to support a major urban redevelopment project in downtown Detroit. American Superconductor’s partner, Pirelli, is participating in this project. The three HTS cables, weighing 250 pounds, will carry 100 megawatts of power, a job that nine copper cables, with a total weight of 18,000 pounds, are doing. In Germany, Siemens AG has invested hundreds of millions of dollars into researching HTS, because the capability can bring improvements across the German conglomerate’s businesses, from power to transportation to electronic devices. The principal commercial US players are American Superconductor, 3M, and Intermagnetics General. Each has organized efforts to develop commercial processes for manufacturing HTS tape based on coated conductors.

Abstract:

Objective Contrast-enhanced cone-beam computed tomography (CBCT) imaging is commonly used for evaluating neurovascular stents and their relationship to the parent artery or vascular pathologies such as arteriovenous malformations (AVMs) and dural arteriovenous fistulas (dAVFs) in the context of surrounding anatomical structures. The purpose of this study was to understand the effects of varying concentrations of contrast medium used in CBCT imaging for optimal visualization of various endovascular devices and anatomical pathologies. Methods Thirty-five patients with various neurovascular pathologies were included in the study. Contrast-enhanced CBCT images (20 s DR, Siemens syngo DynaCT, Siemens AG, Forchheim, Germany) were acquired in all cases, with varying dilutions of contrast medium, from 1% to 30%. The injection rate was kept constant at 3 cc/sec with an X-ray delay of two sec, and a total volume of 66 cc of diluted contrast was administered. Results from visual and quantitative analysis were reported. Results Ten percent dilution of contrast medium resulted in the best image differentiation between flow-diverter devices and the parent artery. Concentrations as low as 2.5% contrast medium also resulted in identifying AVMs in the context of the surrounding brain parenchyma, whereas 20% to 30% dilution provided the best visualization of residual AVMs with prior Onyx embolization and dAVFs in the presence of bony structures. Conclusions Simultaneous visualization of brain parenchyma, bony structures, devices, and pathological anatomy using contrast-enhanced CBCT imaging is feasible with appropriate doses of iodinated contrast, and should be tailored to the individual case based on the goals of CBCT.

Abstract:

Superconducting cryo-electron microscope (SCM) has been mainly applied to the biological field, due to the advantages such as reduction of radiation damage and the possibility of a perfectly contamination-free environment. From the material science view point, microstructural characterization at liquid helium temperature is an attractive technique. In this presentation, some topics concerning the low temperature physics of ceramics will be discussed on the basis of the data obtained using high resolution SCM.The principle of the superconducting lens (SCL) was first described by the Dietrich Group of Siemens AG, West Germany in 1966, following this by fitting a SCL as the objective lens of a 200kV electron microscope, a new type of electron microscope, the JEM-2000SCM, was developed by JEOL LTD, Japan. A detailed cross-sectional diagram of the SCL is shown in Fig.1. A spherical aberration coefficient of 1.2mm was obtained.

Abstract:

Zusammenfassung Das Ziel dieser Arbeit bestand in der Entwicklung eines langwelligen Strahlungsthermometers zur berührungslosen Messung von Oberflächentemperaturen in stationären Gasturbinen während des Betriebs der Turbinen innerhalb des EU-geförderten Projektes „Sensors Towards Advanced Monitoring and Control of Gas Turbine Engines (Acronym STARGATE)“. Im Rahmen der Arbeit wurden die infrarot-optischen Eigenschaften der Wärmedämmschichten und der vorhandenen Brenngase am ZAE Bayern bei hohen Temperaturen bis 1600 K und Drücken bis 13 bar bestimmt. Mit Hilfe dieser experimentellen Charakterisierungen konnte ein geeigneter Spektralbereich um 10 μm für das langwellige Strahlungsthermometer identifiziert werden. Entsprechend dieser Erkenntnisse wurde zunächst ein Laboraufbau mit geeigneten optischen Bauteilen (Filter, IR-Wellenleiter, etc.) realisiert und verifiziert. Anschließend wurde ein Prototyp für Messungen in Gasturbinen während des Betriebs der Turbinen entwickelt und in einem Turbinenteststand der Firma Siemens AG in Berlin erfolgreich getestet. Abschließend wurde eine Unsicherheitsanalyse durchgeführt, die eine erweiterte Messunsicherheit der gemessenen Temperaturen von etwa ± 30 K ergab.

Abstract:

Debates over whether transnational and international legal institutions are fair, effective, or legitimate responses to corruption of local public officials have an important empirical dimension. We use case studies to examine whether foreign legal institutions serve as fair, effective, and legitimate complements to local anticorruption institutions. We refer to this set of claims as the “institutional complementarity theory.” The first case study centers on proceedings concerning bribes paid by subsidiaries of Siemens AG, a German company, to obtain and retain a contract to provide national identity cards for the Argentine government. The second case study examines events stemming from overbilling in the construction of a courthouse in Brazil. Analysis of these cases suggests that the institutional complementary theory is credible. At the same time, the findings suggest that local institutions have greater potential, and foreign institutions have more limited potential, than the theory assumes.

Abstract:

Faster development of innovative machine tools, shorter processing times, improved surface quality of workpieces, higher machine productivity – these are just a few of the wishes and demands of machine manufacturers and end-users. Time-to-market is decisive; in some industries, six months too late on the market can already be decisive in losing the race for market leadership. The key to success lies in virtual techniques. These are an extremely cost-effective way to increase productivity in all phases of the machine tools life cycle. Siemens AG, the leading provider for control and drive technology, sees itself as a partner for the whole machine tool industry and offers four phases of simulation support which cover the entire life cycle of a machine: Mechatronic Support for simulation for machine development, Machine Simulator for supporting commissioning, Virtual Production for the optimization of production and, finally, Virtual NC Kernel (VNCK) for the testing of NC part programs at the end-user.

Abstract:

Abstract Background Three-dimensional mapping systems and the use of ultra-low dose radiation protocols have supported minimization of radiation dose during left atrial ablation procedures. By using optimal shielding, scattered radiation reaching the operator can be further reduced. This prospective study was designed to determine the remaining operator radiation exposure during left atrial catheter ablations using real-time dosimetry. Methods Radiation dose was recorded using real-time digital dosimetry badges outside the lead apron during 201 consecutive left atrial fibrillation ablation procedures. All procedures were performed using the same X‑ray system (Siemens Healthineers Artis dBc; Siemens Healthcare AG, Erlangen, Germany) programmed with ultra-low dose radiation settings including a low frame rate (two frames per second), maximum copper filtration, and an optimized detector dose. To reduce scattered radiation to the operators, table-suspended lead curtains, ceiling-suspended leaded plastic shields, and radiation-absorbing shields on the patient were positioned in an overlapping configuration. Results The 201 procedures included 139 (69%) pulmonary vein isolations (PVI) (20 cryoballoon ablations, 119 radiofrequency ablations, with 35 cases receiving additional ablation of the cavotricuspid isthmus) and 62 (31%) PVI plus further left atrial substrate ablation. Mean radiation dose measured as dose area product for all procedures was 128.09 ± 187.87 cGy ∙ cm2 with a mean fluoroscopy duration of 9.4 ± 8.7 min. Real-time dosimetry showed very low average operator doses of 0.52 ± 0.10 µSv. A subanalysis of 51 (25%) procedures showed that the radiation burden for the operator was highest during pulmonary vein angiography. Conclusion The use of ultra-low dose radiation protocols in combination with optimized shielding results in extremely low scattered radiation reaching the operator.

Abstract:

In this study, the movable flame hardening process of 12Cr steel for a uniform hardness and desirable residual stress have been investigated. For this, the temperature cycles have been controlled accurately as a function of the three processing variables, the flame intensity If, the scanning velocity Vs and the initial flame holding time th, where the standard surface temperature Ts,max was maintained at 960oC. The optimized conditions were Vs=0.68mm/s and th=67sec for the C3H8:O2=5:20 l/min, Vs=0.80mm/s and th=56sec for the C3H8:O2=6:24 l/min, Vs=1.01 mm/s and th=48sec for the C3H8:O2=7:28l/min, and Vs=1.15 mm/s and th=39sec for the C3H8:O2=8:32l/min. The optimally flame-hardened surface exhibited uniform distributions of the hardness and residual compressive stress over the treated area with moderate levels of 470~490HV0.2 in hardness and -300~-450MPa in residual stress, which were acceptable on the basis of the acceptance criteria of Siemens AG-KWU and GE Power Generation Engineering.
