On the enhancement of heat transfer in pulsating combustion flows

It has been observed and reported that in pulse combustors of Helmholtz type the heat transfer is two to five times higher than expected. From experiments, where the temperature profile in the tail pipe of a pulse combustor has been measured, we have no indication why the heat transfer should be enhanced. In the tail pipe of a pulse combustor the radial component of the temperature gradient vanish

On a Contingency Framework of Computerized Information Systems

In this paper a conceptual model of the environment of computerized information systems is developed. The purpose of the model is to describe computerized information systems in relation to contextual factors of the organization. It is proposed that the characteristics of a computerized information system can be classified first in terms of data base, reports or processing, and second in terms of

The impossibility of an ethical consumer

The thesis of this article is that the notion of an ethical food consumer is untenable unless it is coupled with a conception of food citizenship. The main arguments delivered against the notion of ethical food consumption are that consumption does not take the operations of moral psychology into account, nor afford means to tackle structural problems inherent in the relation between consumer and

Photoreceptors in experimental retinal cell transplants

Popular Abstract in Swedish Näthinnan (retina) spelar en central roll för vår förmåga att se. Den sitter längst bak i ögat och precis på samma sätt som objektivet i en kamera fokuserar en bild på filmen, fokuserar ögats "objektiv", dvs. hornhinnan och linsen, en bild på näthinnan. Denna bild, bestående av ljus av olika färg och intensitet, omvandlas av näthinnan till elektriska nervsignaler som skThe main objective of this thesis was to investigate the fate of photoreceptor cells when using different strategies for retinal cell transplantation. Comparing transplantation of fragments of embryonic retina with cell suspensions of the same tissue we found that transplantation of fragments of embryonic retina result in mature transplants with a higher degree of cellular organization than transp

The Escalation of Hostilities in Manchuria, 1945-47: A Study of Strategic Realities and Normative Guidelines in Military Conflict in the Context of the Chinese Civil War

This dissertation is a revisionist study of the early stages of the Chinese Civil War with a focus on the conflict in the Manchurian theatre. The military operations in Manchuria during the late 1940s were pivotal to the outcome of the Chinese Civil War, which in turn determined the political landscape of contemporary China. Clarifying the strategies employed by both sides, this study advances bey

Ni ska bli ett gott parti

Om kvinnosynen i Sverige under 1940-50-talen, där den professionella husmodern var ett ideal. Kapitlet handlar om Hushållsskolan på slottet Skarhult i Skåne under denna tid.

The Exchange-Value of Solar Thermal Energy

In Sweden there is a tendency that alternative energy will develop on market premises. In this paper I suggest that the low exergy value of solar thermal energy limits the technique's commodification, i.e. the possibility of having a commercial exchange-value on the market. Anthropologists argue that value of a commodity has to be related to social and cultural aspects of the society where it is s

Computer-Aided Planning of Working and Living Environments for Disabled People

A research program for the development of a method for computer-aided planning of homes and working environments for disabled people has recently started. The method is being tested at rehabilitation centres in realistic planning situations and has obtained positive response from both the disabled persons and the professionals such as occupational therapists. The requirements and features of the c
