The automobile with a combustion engine forms a fundamental part of our transport system and will retain this importance in the years to come. The development of even more efficient engines is therefore an important field of research. In the field of gasoline engines, charge stratification by means of multiple injection offers particular potential for this. The aim of this work is to investigate the internal engine processes with a focus on identifying possible causes of cycle-to-cycle fluctuations. For this...

The energy conversion in combustion engines plays an important role both for the flow of goods and for individual transport. From the point of view of the scarcity of raw materials and the constant growth in population, a detailed understanding of the physical relationships is necessary in order to be able to carry out this conversion process with optimal efficiency and thus efficient use of resources. The aim of this work is to gain a deeper understanding of the internal...

The combustion of hydrocarbons in a gas turbine will form the basis for aircraft propulsion for the foreseeable future. In order to minimize the environmental impact of this technology, novel combustion processes must be developed and loss processes within the gas turbine combustion chamber optimized. Current research areas relate to lean premixed combustion and the optimization of the cooling air requirement of the effusion-cooled combustion chamber wall. The aim of this work is to set up a gas turbine combustor...

How should learning objects be selected so that they can develop the human ability that is necessary to actively help shape the life and work environment of the students? This thesis presents a model that can be used to make better use of the degrees of freedom that were transferred to teachers in the vocational education system through the introduction of the learning fields, and would thus encourage further curricular interventions and discussions. Details Title: Fields of learning as a...

"Together we are changing the rules of pornography." This is what the burgeoning (queer) feminist porn scene promises. But according to what rules does pornography work? And to what extent are new porn makers trying to break with the usual norms and forms of representation? On the one hand, pornography stands for female objectification, male-dominated pleasure images and gender stigmatization. On the other hand, it stands for sexual self-empowerment, sex positivism and the expression of one's own sexuality independent of...

In her work, the author first presented the essentials of the theory, empiricism and method of Maria Montessori and Emmi Pikler. In the practical part, she shows how these methods are used today, based on observations in a crèche and an interview with a kindergarten teacher. The work is therefore interesting for educators, but also for parents who have children in institutions that work according to Montessori and/or Pikler. In the final part, the connection is made between the theory...

The international interdependence of markets and economic relations presents the operating companies with new tasks and additional challenges. However, in intercultural economic conflicts that arise in the area of ​​tension between global integration and cultural identity, the tried-and-tested negotiation patterns and mechanisms of conflict resolution in the respective home culture quickly reach their limits. Time-consuming and costly court proceedings usually only lead to the formal clarification of legal claims by the parties involved, but are unsuitable for creating the basis...

The role of Islam in Indonesia's recent political and civil society history has been the subject of controversial discussions for years. Since the overthrow of Suharto in 1998, and in the course of the democratization process that began thereafter, militant Islam in particular has increasingly attracted the attention of world public opinion, in addition to the large number of newly emerging Islamic-influenced parties. Klaus Behnam Shad's work is dedicated to the question of how the highly complicated relationship between domestic...

Buyer power is playing an increasing role in the competition policy discussion, especially against the background of an ever more concentrated food retail trade. Current case law as well as proceedings and investigations by the Federal Cartel Office have recently brought the topic into the focus of science.The present study comes to the conclusion that buyer power manifests itself in the form of bilateral bargaining power and provides the legal practitioner with criteria for their existence. In addition, she examines...

The use of mobile devices and the sale of mobile applications/applications (apps) continue to increase rapidly. It is expected that smartphones will soon replace computers and laptops as the most used end device. These trends result in new challenges for companies across all industries, which put great pressure on them. The only way companies can withstand this pressure and stay competitive is to develop their own mobile strategy and ensure that strategy is aligned with overall corporate strategy. On the...

The outstanding importance of phosphorus (P) in all living cells makes it an essential nutrient. Its pivotal use as a fertilizer and the finiteness as a natural resource lead to a new episode of historic importance: A possible upcoming phosphate crisis. In this book an overview of the role of phosphorus as a nutrient and as a fertilizer as well as the underlying soil dynamics is given. The flows of phosphorus in Austria are shown by using the method of...
