This paper analyses the conditions for which the results of eddy currents computation in thin regions modelled by surface regions are concordant with those obtained using volume finite elements. The concepts of geometrically thin or thick region, electromagnetically thin or thick region, 2D or 3D problem, transverse or longitudinal flux problem are used to characterise the limits of the surface model. The computation of eddy currents in sheets heated in transverse flux inductors and of the eddy current losses in metallic casing of an induction furnace highlights the surface finite element applicability.

Analysis and development of a high efficiency, induction heated chemical reactor, medium frequency supplied (1,000‐2,000 Hz), able to be equipped with efficient cooling circuits.

The numerical investigations of the technical solutions proposed in this paper are based on 3D finite element models that are experimentally validated.

Solutions to increase the transparency of the cooling envelope of the reactor tank with respect to magnetic field. The positions of envelope regions characterized by high values of power losses are experimentally confirmed by infrared temperature measurements.

The numerical analysis and the experimental investigations, show the possibility to implement efficient cooling circuits in chemical reactors without affecting the performances of the induction heating process. By designing properly the metallic envelope of the tank the global efficiencies of the chemical reactors increase at around 90 percent with reduced impact on the working environment and with low costs.

This paper proposes an innovative chemical reactor medium frequency induction heated with efficient cooling circuits and with high global efficiency, higher than the actual induction heated chemical reactors.

Shortly before the Second World War, a woman who had never accepted her orphan status, Gabrielle Bonheur Chanel, nicknamed ‘Little Coco’ by her father and known as ‘Coco’ to her relatives, became the first women in history to build a world-class industrial empire. By 1935, Coco, a fashion designer and industry captain, was employing more than 4,000 workers and had sold more than 28,000 dresses, tailored jackets and women's suits. Born into a poor family and raised in an orphanage, she enjoyed an intense social life in Paris in the 1920s, rubbing shoulders with artists, creators and the rising stars of her time.

Thanks to her entrepreneurial skills, she was able to innovate in her methods and in her trendsetting approach to fashion design and promotion. Coco Chanel was committed and creative, had the soul of an entrepreneur and went on to become a world leader in a brand new sector combining fashion, accessories and perfumes that she would help shape. By the end of her life, she had redefined French elegance and revolutionized the way people dressed.

The purpose of this article is expository in the main; critical to a lesser degree. It will attempt to show how Karl Marx, enraged by the imperfections and inhumanity of the capitalist society, “fought” for its supersession by the communist society on which he dwelt so fondly, that society which would emerge from the womb of a dying capitalism. It asks such questions as these: Is it possible to create the truly human society envisaged by Marx? Is perfection of man and society a mere will‐o'‐the‐wisp? A brief analysis, therefore, of the imperfections of capitalism is undertaken for the purpose of revealing the evils which Marx sought to eliminate by revolution of the most violent sort. In this sense, the nature of man under capitalism is analysed. Marx found the breed wanting, in a word, dehumanised. An attempt is, therefore, made to discuss the new man of Marxism, man's own creation, and the traits of that new man, one freed at last from the alienating effects of private property, division of labour, money, and religion. Another question that springs to mind is this: how does Marx propose to transcend alienation?

The purpose of this paper is to discuss the transforming effect of pursuing person centered ethnography using contemporary reflexive methods and a cultural traditions model on a researcher in late life. It attempts to show the usefulness of life history research as a lens through which to examine the complex ways people age. It adds to literature dealing with ethnographic studies of aging women and demonstrates personal narrative as a way to convey information. Lastly it demonstrates the value of studies pursued by researchers in old age, and illuminates aspects of ethnographic work when women interview women.

Using a journey format, the paper uses personal narrative as a way to achieve its goals. The personal account is complemented by noting other ethnographic studies that have contributed to age studies literature, and it draws attention to the value of reflexivity in good ethnographic work as proposed by anthropologists Barbara Myerhoff and John Caughey.

The paper points toward research institutions who study aging valuing ethnographic findings and making use of researchers in old age to engage in ethnographic studies. It points to the possibility that elders engaged in such research may strengthen their sense of self and empower them as they make a contribution to age studies.

This paper deals with the transformative power of engaging in reflexive life history research, especially as it is done by an ethnographer in late life. This freeing from customary cultural ways of thinking may be as beneficial to the researcher as life review or reminiscence. This should be explored further.

The paper points to the idea, implicit not explicit, that an elder who engages in reflexive life history research that involves doing a self-ethnography, can benefit in ways similar to having engaged in life review or reminiscence. This is original.

I Die Zukunft — ein dominierendes Betrachtungsobjekt unserer Gegenwart. Ich bin vorerst zum Titel und damit zum Gegenstand dieser Abhandlung einige Erklärungen schuldig.

Alain Bouchard was born in 1949. He bought his first convenience store in 1978, when he was almost 30 years old. By then, he already had nearly 10 years of experience in the sector. He had already been involved in the start-up of more than 200 convenience stores. He understood that if he was to transform his newly acquired store into a chain and build something big, he needed to set up a team of people with complementary skills to help him make acquisitions.

In 2023, there are roughly 15,000 convenience stores operating under the Circle K/Ingo/Couche-Tard banners, employing 130,000 people in more than 30 countries. Annual sales are more than US$60 billion. Alain Bouchard officially retired from his position as President and CEO in 2014 and became Founder and Executive Chairman of the Board. He continues to be a major shareholder. He is still actively involved in strategic orientations and in identifying potential acquisitions. He has become a ‘Chief Culture Officer’ involved in executive leadership mentoring. He has never stopped communicating the importance of innovative, creative and intrapreneurial behaviour at all levels of the enterprise.

This case study presents Alain Bouchard, the man and the entrepreneur. It shows how he learned and mastered the craft of starting, acquiring, managing and developing convenience stores. It looks at how he encouraged the people around him to act as facilitators and intrapreneurs. It describes his values, how he works and learned to live with risk.

Der Tourismus kann nur dort gedeihen, wo das Recht auf seine ungestörte Ausübung anerkannt wird. Das unbedingte Korrelat, nämlich die Pflicht, ein solches Recht umweltfreundlich, menschfreudig und vor allem gemässigt auszuben, ist davon nicht wegzudenken.
