Betrugsmaschen werden wohl nie aussterben. Immer wieder wachsen neue Opfer nach, die unwissend, leichtgläubig oder schnell einzuschüchtern sind. Privatleute und Unternehmer werden dabei gleichermaßen Opfer von geschickten "Vertragsabschlusskonstruktionen", bei deren Durchsetzung zuweilen auch Juristen beteiligt sind. Dieser Beitrag befasst sich mit aktuellen Entwicklungen und Entscheidungen im deutschen Recht zu eben diesen Fällen.
Durch eine stetige Preissteigerung der fossilen Energieträger werden auch im Bereich der mobilen Arbeitsmaschinen neben einer hohen Zuverlässig u.a. Forderungen nach steigenden Gesamtwirkungsgraden, mit der hierdurch einhergehenden Energieeffizienz, forciert. Auch bei mobilen Arbeitsmaschinen ist der häufig eingeschränkt zur Verfügung stehende Bauraum für Traktionsantriebe eine Herausforderung. Ziel dieser Veröffentlichung ist ein allgemeingültiger Vergleich verschiedener elektrischer Antriebsarten als Traktionsantrieb für mobile Arbeitsmaschinen.
Die Kommunikationstechnik für die Zählerfernauslesung (Smart Metering) und für die Energieerzeugungs- und -verteilnetze (Smart Grid) hat das Potenzial, zu einer der ersten hoch skalierten M2M-Anwendungen zu werden. In den vergangenen Jahren konnten zwei vielversprechende Entwicklungen im Umfeld der drahtlosen Kommunikation für die Smart-Grid-Kommunikation vorbereitet werden, die das Marktgeschehen über Deutschland und über die Versorgungstechnik hinaus beeinflussen könnten. Neben der Spezifikation der OMS-Gruppe ist die Erarbeitung eines Schutzprofils (Protection Profile, PP) sowie einer Technischen Richtlinie (TR) für die Kommunikationseinheit eines intelligenten Messsystems (Smart Meter Gateway) durch das Bundesamt für Sicherheit in der Informationstechnik (BSI) zu nennen. Diese greifen, wie der Beitrag beschreibt, den Stand der Technik auf und geben praxisorientierte Umsetzungen vor.
The increased complexity and dynamics of the business environment and the problems of a young organization are treated extensively in the literature [Bleicher 2002, p. 34; Malik 1996, p. 86; Ulrich/Probst 1990, p. 23ff; Gomez 1999, p. 65]. This complexity is the core of the leadership role in a company [Malik 1996, p. 184]. STÜTTGEN (1999, p. 8) states in this regard: "A satisfactory answer to the question, according to which patterns complex social systems are to be designed to meet the proliferating environmental complexity facing an adequate intrinsic complexity of the company can be, in this context, a critical success factor for management." How can young SMEs solve strategic problems with service engineering in their companies?
A 2002 study on corporate planning of the top German companies measured by turnover found that of the surveyed large companies, 80 percent have carried out strategic planning and 90 percent have operational planning in place [Link/Orbán 2002, pp. 11]. The human and material costs of designing and implementing the strategic planning can be very high. Many SMEs do not have the necessary capacities to do this. To obtain a comprehensive overview, this chapter examines the existing studies and findings for young SMEs. Many of the studies reviewed and the following publications relate to SMEs as defined by the EU. This analysis also includes established SMEs and medium-sized enterprises.

A variety of different additive manufacturing processes have been available for the last three decades. Some of these technologies are very energy-intensive, e.g. laser technology and the manufacture of metal powder. In many areas, the detailed investigation of the energy and material consumption of these new manufacturing methods is still in the beginning. This paper investigates energy and material consumption using 3D colour printing (3DP) as an example. The specific energy required for the layering can be determined from this. This then forms the basis for a comparison of the specific energy consumption with other generative (e.g. Fused Layer Modelling—FLM) and also conventional production processes (e.g. milling and grinding). Thus process selection is facilitated by introducing the specific energy for layering. In addition several variables, in which resource consumption can be reduced are also investigated and compared. For example the influence of the geometry or the positioning of the 3D-printed part in the design space on the consumption are investigated. But also the measuring of different batch sizes is compared. Using the results found, the use of 3D printing can initially be optimized so that less energy, resources and manufacturing time are required.
Zielvereinbarungen sollen SMART formuliert werden, um die Leistungsbereitschaft von Mitarbeitern optimal zu fördern - so wird es zumindest in der praxisorientierten betriebswirtschaftlichen Literatur propagiert. Ob Zielvereinbarungen, die spezifisch, messbar, erreichbar, relevant für das Unternehmen und zeitlich terminiert sind, wirklich eine höhere Leistungsbereitschaft zur Folge haben, wird im Folgenden auf Basis einer empirischen Untersuchung überprüft.

Gas adsorption studies of CO2 and N2 in spatially aligned double-walled carbon nanotube arrays
(2013)
Gas adsorption studies (CO2 and N2) over a wide pressure range on vertically, highly aligned dense double-walled carbon nanotube arrays of high purity and high specific surface area are reported. At high pressures, the adsorption capacity of these materials was found to be comparable to those of metal organic frameworks and mesoporous molecular sieves. These highly aligned CNT arrays were chemically modified by treating with oxygen plasma and structurally modified by decreasing the diameter of individual carbon nanotubes. Oxygen plasma treatment led to grafting of a large number of C–O functional groups onto the CNT surface, which further increased the gas adsorption capacity. It was found that gas adsorption is dependent on tube diameter and increases with decrease of the individual CNT diameter in the CNT bundles. As results of our studies we have found that at lower pressure regimes, plasma functionalized carbon nanotubes exhibit better adsorption characteristics whereas at higher pressures, lower diameter carbon nanotube structures exhibited better gas adsorption characteristics.

Various Rapid Prototyping methods have been available for the production of physical architectural models for a few years. This paper highlights in particular the advantages of 3D printing for the production of detailed architectural models. In addition, the current challenges for the creation and transfer of data are explained. Furthermore, new methods are being developed in order to improve both the technical and economic boundary conditions for the application of 3DP. This makes the production of models with very detailed interior rooms possible. The internal details are made visible by dividing the complex overall model into individual models connected by means of an innovative plug-in system. Finally, two case studies are shown in which the developed methods are applied in order to implement detailed architectural models. Additional information about manufacturing time and costs of the architectural models in the two case studies is given.
