Tidskriftsartikel (refereegranskat)abstract
- Presents some theoretical principles and empirical evidence relating to the new Swedish production systems for final assembly of motor vehicles. Contends that in these production systems it is possible simultaneously to enhance efficiency and quality of working life. Briefly sketches three production forms as they apply to the final assembly of automobiles and discusses the societal environments in which these different forms of production have evolved. It focuses on Volvo Uddevalla plant as one of the main examples so far of a reflective production system for final assembly of automobiles. Amplifies the analysis of different production flow patterns for final assembly and in particular addresses the issue of semi‐parallel mechanistic production flow and parallel organic production flow as alternatives to serial flow on a conventional line assembly. A comment: This publication is authored together with e.g. senior research competencies (1) within vocational learning and training as well as (2) within time-geography with whom Engström have had long time cooperation procedures. But also personal at our department/research group (Mats Johansson) well as our knowledgeable contact person (Bertil Johansson) within Volvo contributed (he has really helped us out for decades and was responsible for the continuous contacts with Volvo in most any matter).

Reflektiv produktion – Industriell verksamhet i förnyelse
- 1992
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- This book, a sort of summarization of the authors' insights and experiences regarding group work as well as alternatives to assembly line work from their own scientific perspective, which was made available in 1992. That is, in the (very specific) period of time (or turbulence) while the assembly plants in Uddevalla and Kalmar were closed down (the former assembly plant was closed down first, while the other was shut down approximate a year later). This book has been published by Volvo (AB Volvo Media, ISBN-number: 91 9761 604). It has been published by Arbetslivsutveckling with the editors Lars Cambert and Glenn Carlsson at this department. Moreover, the content has been validated by a number of Volvo experts and discussed at a seminary (among other things, each of these experts had to provide written comments to the two editors etc.). A comment: This publication is authored together with e.g. senior research competencies (1) within vocational learning and training as well as (2) within time-geography with whom Engström have had long time cooperation procedures. But also personal at our department/research group (Mats Johansson) well as our knowledgeable contact person (Bertil Johansson) within Volvo contributed.

Small intestinal differentiation in human colon carcinoma HT29 cells has distinct effects on the lateral diffusion of lipids (ganglioside GM1) and proteins (HLA Class 1, HLA Class 2, and neoplastic epithelial antigens) in the apical cell membrane

Tidskriftsartikel (refereegranskat)abstract
- We have studied the effect of maturation to small intestinal-like epithelial cells of the human colonic calcinoma cell line HT29 on the lateral mobility of different representative membrane components (lipid, proteins), as assessed with fluorescence recovery after photobleaching (FRAP). Maturation was induced in vitro in the HT29 cells by replacing glucose (Glu) with galactose (Gal) in the growth medium (DMEM) during a 21-day period. Scanning electron microscopy revealed an increased number of microvilli in the apical cell membrane, and enzyme analyses (alkaline phosphatase, aminopeptidase) in combination with aqueous countercurrent distribution, indicated that maturation was induced with DMEM-Gal. In comparison to control cells grown in DMEM-Glu medium, the more small intestinal-like cells grown in DMEM-Gal displayed no alteration of the lateral mobility of either cholera toxin (B subuni)-labelled ganglioside GM1 (diffusion coefficient, D [x 108] = 0.8–0.9 cm2s−1; mobile fraction, R = 50-60%) or antibody-stained Class 2 histocompatibility (HLA-DR) antigen (D [x 109] = 2 cm2s−1; R = 60–70%). However, antibody-labelled β2-microglobulin of HLA Class 1 antigen displayed increased mobility in HT29-Gal cells; D was × 1.4 and R × 1.8 larger in the HT29-Gal cells. By contrast, the mobility of a neoplastic antigen was reduced; D and R were × 0.60 and × 0.69 of the values seen in HT29-Glu cells. It is thus concluded that DMEM-Gal-induced differentiation in confluent HT29 cells is accompanied by specific rather than general effects on the lateral mobil-ity of different membrane components.
