The greatly increased performance of both civil and military aircraft since the Second World War has raised problems undreamt of at an earlier period and, from the simple measures originally introduced to improve pilot’s well-being, have sprung the complex installations which are now essential for human survival and comfort and to ensure the proper functioning of vital equipment carried in present day machines.The term “Environmental Control System” is used for convenience to cover collectively the various cabin and equipment bay, pressure, temperature and humidity control systems that are fitted.

This article seeks to demonstrate how Finnish refugee children experienced living in Swedish refugee camps during the Second World War (1939–1945). The study focuses on children’s opinions and experiences reflected through adulthood. The data were collected through retrospective interviews with six adults who experienced wartime as children in Finland and were evacuated to Sweden as refugees. Five of the interviewees were female and one of them was male. The study shows, it was of decisive importance to the refugee children’s well-being to have reliable adults around them during the evacuation and at the camps. The findings demonstrate that careful planning made a significant difference to the children´s adaptations to refugee camp life. The daily routines at the camp, such as regular meals, play time and camp school, reflected life at home and helped the children to continue their lives, even under challenging circumstances.

Abstract We construct long-run sustainability indicators based on changes in Comprehensive Wealth - which we refer to as Genuine Savings (GS) - for Germany over the period 1850-2000. We find that German sustainability indicators are positive for the most part, although they are negative during and after the two World Wars and also the Great Depression. We also test the relationship between these wealth changes and a number of measures of well-being over the long-run: changes in consumption as well as changes in average height and infant mortality rates. We find a positive relationship between GS and our well-being indicators over different time horizons, however, the relationship breaks down during WWII. We also test if the GS/Comprehensive Wealth framework is able to cope with massive disinvestment at the end of the Second World War due to war-related destructions and dismantlement. We find that negative rates of GS were by and large avoided due to the accumulation of technology and growth-friendly institutions. We demonstrate the importance of broader measures of capital, including measures of technological progress, and its role in the process of economic development; and the limits of conventional measures of investment to understand why future German consumption did not collapse.

The forensic investigation of military aircraft crash sites has become in recent times part of mainstream traditional archaeology. Mostly amateur aircraft enthusiasts have undertaken the recovery of military aircraft crash sites without methodically recording the remains. The sites covered in this paper have been approached based on recording the in-situ remains methodically using traditional and scientific methods used in the field of archaeology from fieldwalking, metal detecting and geophysics. The strategy and methodology used in this investigation showed how effective and important it is to recover as much of the remains as possible to place it into a meaningful context in order to understand the reasoning for why these aircraft came to a devasting end by crashing into the ground at great speed. The excavations have involved Operation Nightingale—an MOD based recovery programme that specializes in archaeology. This paper will demonstrate the importance of using such an integrated approach to the recovery of military aircraft crash sites from the Second World War by referring to specific case studies.

For some considerable time, experience has been accumulated on the retardation of military aircraft on landing by means of a brake parachute. A patent for such a device, for example, was granted to Captain, now Colonel, Prospero Freri, in Italy in 1930. The first useful applications were towards the end of the Second World War on gliders and fighter aircraft, but systematic use of this type of decelerator on American aircraft began just before 1950. The first postwar British service aircraft fitted with a brake parachute was the Vulcan, followed closely by the Lightning and the Victor. These three aircraft use brake parachutes to reduce the landing run and also to reduce wear and tear on the aircraft brakes and tyres. The Lightning in particular has been the subject of extensive application of the brake parachute.

Resumen La condición de arquitectura alternativa apunta a procesos individualistasalejados de convencionalismos de contexto. La internacionalización de los postulados modernos condujo a la crítica a eludir en sus análisis construcciones de revitalización de una arquitectura considerada comoexcesivamente identitaria. Este artículo analiza el esfuerzo del arquitectoegipcio Hassan Fathy (1900-1989) por reivindicar, a todas las escalas, lasabiduría de la edificación tradicional durante un periodo coincidente con la modernidad occidental. La escasez de hierro y cemento en Egipto, tras la II Guerra Mundial, fomentó la recuperación de una construcción de bajo coste adaptada a las circunstancias y recursos materiales del lugar. La durabilidad de la arquitectura popular que permanecía conservada desde tiempos remotos, y sobre todo su eficacia en el control climático, fomentó en Fathy el deseo de aprendizaje de métodos y dispositivos tradicionales tanto constructivos como espaciales que fueron reinterpretados con una lectura moderna, desde el ámbito doméstico al urbano, en la morfología y materialización de sus proyectos.AbstractThe “alternative” architectural condition points to individualistic processes that give results far removed from the conventionalisms of context. The internationalization of the modern postulates led the critique to leave constructive procedures in the analyses of revitalization of an architecture considered as excessively identitarian, to one side.This article analyses the effort of the Egyptian architect Hassan Fathy (1900-1989) to defend at all levels, during a period coinciding with Western modernity, the wisdom of traditional inherited edification.The scarcity of iron and cement in Egypt, after the Second World War, boosted the recovery of a low-cost construction adapted to the climatic conditions and the material resources available locally. Popular architecture’s durability, especially its utilitarian aspect, preservedsince ancient times and, in particular, its effectiveness in climate control, inspired in Fathy the desire to learn traditional constructive and spatial devices. The questioning of the figure of the “Muallim”, or Master Mason, which had become a source of inherited knowledge, with regards vernacular constructive systems, added to his own analysis of popular architecture, gave him a knowledge of autochthonous materials and passive  mechanisms of environmental control that were reinterpreted with a modern reading in the materialization of both his domestic and urban projects.

This article examines how Northern Rhodesian ex-servicemen experienced home life after the Second World War, the problems they encountered, and the society into which they were reintegrated. Challenges faced by African veterans made them restless and discontented compared to European ex-servicemen who benefited from entrenched discriminatory racial practices. Using hitherto unexplored materials from the National Archives of Zambia, this article further argues that African ex-servicemen were preoccupied with their immediate personal well-being and not wider societal issues such as nationalism. This stands in contrast to older academic arguments that African ex-servicemen played a vital role in nationalist politics.

The welfare state is a relatively new social phenomenon. Its rudimentary forms appear at the beginning of the 20th century, and it was especially developed immediately after the Second World War. It was created in order to reduce acute social conflicts in societies around the world and to give citizens the minimum conditions for subsistence. From its founding, to this day, the welfare state is at the center of the attention of the professional and general public. This article attempts to define and categorize a state of well-being, but also to consider modern trends that reflect it. Particular attention will be paid to reducing the welfare state and the reasons why it occurs. From the many factors that are often considered in the context of the decline of the welfare state, here we will primarily analyze the demographic, economic and political factors.

Education is life and life is education. Education is very much necessary for making the citizens alert and capable of discharging their duties and responsibilities efficiently and wisely. Education is necessary not only for enabling man to participate in the affairs of the society and the government but also to save mankind from destruction and extinction. Many of us have realised the devastating effects of the second world war. A third such war will result in total extinction of human race. The need of the hour is understanding and international understanding, mutual love and respect for each other’s well being which can be developed through education. In the year 1946, the International Community charged UNESCO with the responsibility of promotion throughout the world due to its vital importance to the individual and social well-being. The United Nations proclaimed universal declaration of human rights. Article 45 of the Indian Constitution says that, the state shall endeavour to provide, “Universal, free and compulsory education to all children upto the age of 14 years within 10 years from the date of adoption of the constitution. The Education Commission (1964-66) holds that education is the powerful instrument which can bring changes in the society.
