This paper describes how four European navies have been able to work together for over twenty years in order to support their marine Tyne, Olympus and Spey gas turbines, used for surface ship propulsion, through two internationally agreed Memoranda of Understanding (MOUs). It shows how the MOUs came into existence, what their main aims are, how they are organised and how MOU business is conducted to achieve these aims. The final part of the paper discusses the merits of the existing MOUs and presents an insight into how they, and other MOUs currently under discussion, may develop in the future.

The future of medicine belongs to immunology and alergology. I tried to not be too wide in description, but on the other hand to mention the most important concepts of alergology to make access to these diseases more understandable, logical and more useful for our patients, that without complex pathophysiology and mechanism of immune reaction,we gain some basic insight into immunological principles. The name allergy to medicine was introduced by Pirquet in 1906, and is of Greek origin (allos-other + ergon-act; different reaction), essentially representing the reaction of an organism to a substance that has already been in contact with it, and manifested as a specific response thatmanifests as either a heightened reaction, a hypersensitivity, or as a reduced reaction immunity. Synonyms for hypersensitivity are: altered reactivity, reaction, hypersensitivity. The word sensitization comes from the Latin (sensibilitas, atis, f.), which means sensibility,sensitivity, and has retained that meaning in medical vocabulary, while in immunology and allergology this term implies the creation of hypersensitivity to an antigen. Antigen comes from the Greek words, anti-anti + genos-genus, the opposite, anti-substance substance that causes the body to produce antibodies.

In 2015, the UK government published the National Strategic Defence and Security Review (SDSR) 2015, which laid out their vision for the future roles and structure of the UK Armed Forces. SDSR 2015 envisaged making broader use of the Armed Forces to support missions other than warfighting. One element of this would be to increase the scale and scope of defence engagement (DE) activities that the UK conducts overseas. DE activities traditionally involve the use of personnel and assets to help prevent conflict, build stability and gain influence with partner nations as part of a short-term training teams. This paper aimed to give an overview of the Specialist Infantry Group and its role in UK DE. It will explore the reasons why the SDSR 2015 recommended their formation as well as an insight into future tasks.

Variable Power

Gas turbines have been accepted in naval surface ship applications, and considerable effort has been made to improve their fuel consumption, particularly at part-load operation. This is an important parameter for shipboard engines because both propulsion and electrical-generator engines spend most of their lives operating at off-design power. An effective way to improve part-load efficiency of recuperated gas turbines is by using a variable power turbine nozzle. This paper discusses the successful use of variable power turbine nozzles in several applications in a family of engines developed for vehicular, industrial, and marine use. These engines incorporate a variable power turbine nozzle and primary surface recuperator to yield specific fuel consumption that rivals that of medium speed diesels. The paper concentrates on the experience with the variable nozzle, tracing its derivation from an existing fixed vane nozzle and its use across a wide range of engine sizes and applications. Emphasis is placed on its potential in marine propulsion and auxiliary gas turbines.

Purpose – This article aims to provide insight into the future of financial markets and regulation in order to define what would be the best strategy for Europe. Design/methodology/approach – First the authors define the potential changes in financial markets and then the tools available for the regulator to tame them. Finally, they build five scenarios according to the main evolutions observed on the financial markets and on the tools used by the regulator to modify these trends. Findings – Among the five scenarios defined, two present highly unstable features since the regulator refuses to choose between financial opening and independently determining how to regulate finance in order to preserve financial stability. Three of them achieve financial stability. However, they are more or less efficient or feasible. In terms of market efficiency, the multi-polar scenario is the best and the fragmentation scenario is the worst, since gains of integration depend on the size of the new capital market. Regarding sovereignty of regulation, fragmentation is the best scenario and the multi-polar scenario is the worst, because it necessitates coordination at the global level which implies moving further away from respective national preferences. However, the more realistic option seems to be the regionalisation scenario: this level of coordination seems much more realistic than the global one; the market should be of sufficient size to enjoy substantial benefits of integration. Nevertheless, the “European government” might gradually increase the degree of financial integration outside Europe in line with the degree of cooperation with the rest of the world. Originality/value – Foresight studies on financial markets and regulation are quite rare. This may be explained by the difficulty to forecast what will be their evolution in the coming decades, not least because finance is fundamentally unstable. This paper provides a framework to consider what could be the best strategy of regulators in such an unstable environment.

Over Time

The growing need to increase the competitiveness of industrial systems continuously requires a reduction of maintenance costs, without compromising safe plant operation. Therefore, forecasting the future behavior of a system allows planning maintenance actions and saving costs, because unexpected stops can be avoided. In this paper, four different methodologies are applied to predict gas turbine behavior over time: Linear and Non Linear Regression, One Parameter Double Exponential Smoothing, Baesyan Forecasting Method and Kalman Filter. The four methodologies are used to provide a prediction of the time when a performance limit will be exceeded in the future, as a function of the current trend of the considered parameter. The application considers different scenarios which may be representative of the trend over time of some significant parameters for gas turbines. Moreover, the Baesyan Forecasting Method, which allows the detection of discontinuities in time series, is also tested for predicting system behavior after two consecutive trends. The results presented in this paper aim to select the most suitable methodology that allows both trending and forecasting as a function of data trend over time, in order to predict time evolution of gas turbine characteristic parameters and to provide an estimate of the occurrence of a failure.

As one location boasting high broadband speeds, infrastructure, strong techno-nationalist policy and some of the early examples of so-called ‘digital natives’, South Korea has been seen as the model for the future of online culture. However, beyond these images of techno-fantasies is a technoculture that is marred by an increasing ambivalence towards online media. Specifically through user-created content (UCC), researchers can gain insight into some of the paradoxes emerging around online creativity, community and politics. Drawing on fieldwork conducted between 2009 and 2011, this article considers what UCC means in Korea and how this reflects the particularities of Korea's technoculture.

Ethical Stance

In this essay James Corby questions the dominant future-oriented nature of the ethical turn of theory and philosophy in the final decades of the twentieth century and its aesthetic influence. Focusing in particular upon the ethical position of Jacques Derrida, Corby argues that the desire to avoid the closure of the contemporary and to preserve the possibility of difference by cultivating a radical attentiveness to that which is ‘to come’ often risks a too complete disengagement from the present, leading to an empty and ineffectual ethical stance that actually preserves the contemporary situation that it seeks to open up. Corby makes a case for this theoretical investment in the possibility of a non-contemporary (typically futural) rupture as being understood as forming part of a far-reaching romantic tradition. In opposition to this tradition he sketches a post-romantic alternative that would understand difference as an immanent, rather than imminent, matter. He argues that this should be considered congruent with a countertextual impulse oriented not towards a revelatory futurity, but, rather, towards the possible displacements, dislocations, and transformations already inherent in the contemporary. The final part of the essay develops this idea, positioning countertextuality as the articulation of alternative contemporaries. In this regard, the literature of the future is not ‘to come’, it is already here. The challenge is to recognise it as such, and this means being prepared to modify and change the conceptual apparatus that guides us in our thinking of literature and the arts.

The main goal of this paper is to provide a descriptive analytical overview of the existing evolution of the Slovenian parliamentary arena since its transition to democracy and independence. The paper is divided into two main parts: (1) an overview of a normative insight into the parliamentary and party system, and (2) an analytical assessment of the structure of the parliamentary arena as it is reflected in electoral and parties’ choices and policy preferences. A look at the contemporary democratic parliamentary arena in Slovenia shows that it, in itself, has been quite stable, while, on the contrary, its main integral parts – political parties – have gradually become less stable and less predictable, especially in the second decade of democracy, which can potentially influence the future stability of parliamentary arena, too.

Insight Into

In 1976, Hans Penth, pioneering scholar of Lanna, published a catalogue of over three hundred Buddha statues bearing inscriptions and dating from the fifteenth through twentieth centuries found in central Chiang Mai monasteries. This invaluable record is here analyzed in depth as a whole for the first time. It provides further insight into the relationship between Buddha images and donors. Statues were often sponsored through collaboration, reflecting the image’s role in materializing sociokarmic groupings seen as extending through the future. Donor resolutions reflect the significance of producing Buddha statues for Buddhism’s future prosperity as well as for donors’ individual spiritual and material aspirations. Images are often described by material and size, reflecting the relation between financial donation and merit generated. Also, refurbishments to statues indicate how they were never seen as finished, nor their appearance seen as sacrosanct; a statue is a palimpsest of its interactions with devotees through time.
