- The purpose of this paper is to discuss how to design entrepreneurial mindsets in different academic cultures and its motives with focus on engineering and management education. Empirical data are collected from, Sweden, Ukraine and India in a ten-year period from 1998-2009. The theoretical framework is based on an integrated view of innovation, design and entrepreneurship sciences. Our findings are that it is quite possible to open up more traditional or narrow mindsets of engineering and management to more broad and multi-scientific approaches, relevant in our complex world. An entrepreneurial mindset has close links to innovation and is characterized by relentless pursuit of opportunities, thinking different, intuitive and executive, is risk-taking and eliminates pre-existing routines. It focuses more on technology and business creation than on state-of-the art technology and business administration. In this approach the culture and climate in an organization and the eco-system around the universities also can be changed to high-light creativity, design and innovation. We have learnt that a strong, open and visionary leadership is necessary in such a challenging work.

- Cereals accumulate starch in the endosperm as their major energy reserve in the grain. In most cereals the embryo, scutellum, and aleurone layer are high in oil, but these tissues constitute a very small part of the total seed weight. However, in oat (Avena sativa L.) most of the oil in kernels is deposited in the same endosperm cells that accumulate starch. Thus oat endosperm is a desirable model system to study the metabolic switches responsible for carbon partitioning between oil and starch synthesis. A prerequisite for such investigations is the development of an experimental system for oat that allows for metabolic flux analysis using stable and radioactive isotope labelling. An in vitro liquid culture system, developed for detached oat panicles and optimized to mimic kernel composition during different developmental stages in planta, is presented here. This system was subsequently used in analyses of carbon partitioning between lipids and carbohydrates by the administration of C-14-labelled sucrose to two cultivars having different amounts of kernel oil. The data presented in this study clearly show that a higher amount of oil in the high-oil cultivar compared with the medium-oil cultivar was due to a higher proportion of carbon partitioning into oil during seed filling, predominantly at the earlier stages of kernel development.

- While the effects of elevated atmospheric CO2 level on starch and sugar metabolism have been extensively studied in different plants, the effect on plant lipid metabolism concerns only a few studies and none of these are on the model plant Arabidopsis thaliana. This study of the lipid composition in seeds and leaves of A. thaliana is therefore of interest when trying to predict how the future environment will change the conditions for plant lipid metabolism and oil crop productivity. Total leaf lipid concentration on a dry weight basis, starch excluded, was 15% lower at elevated CO2 compared to ambient. The fatty acid profile of total leaf lipids showed large diurnal variations, oleic acid increased 2-fold during the first 9 h of illumination and decreased correspondingly during night as expected of the light dependence of de novo fatty acid synthesis. Elevated CO2 did not induce any large differences in this diurnal pattern. However, elevated CO2 induced a 24% lower ratio trans Δ3hexadecenoic acid to palmitic acid in phosphatidyl glycerol. With good nutrient supply, growth at elevated CO2 did not affect either single seed weight, total seed mass, oil yield, or fatty acid profile of seeds significantly. This study shows that elevated atmospheric CO2 cause changes in leaf lipid metabolism in the plant A. thaliana, however, no large differences in seed lipids can be observed.

- Few studies regarding the effects of elevated atmospheric CO2 concentrations on plant lipid metabolism have been carried out. Here, the effects of elevated CO2 concentration on lipid composition in mature seeds and in leaves during the diurnal cycle of Arabidopsis thaliana were investigated. Plants were grown in controlled climate chambers at elevated (800 ppm) and ambient CO2 concentrations. Lipids were extracted and characterized using thin layer chromatography (TLC) and gas liquid chromatography. The fatty acid profile of total leaf lipids showed large diurnal variations. However, the elevated CO2 concentration did not induce any significant differences in the diurnal pattern compared with the ambient concentration. The major chloroplast lipids monogalactosyldiacylglycerol (MGDG) and phosphatidylglycerol (PG) were decreased at elevated CO2 in favour of phosphatidylcholine (PC) and phosphatidylethanolamine (PE). Elevated CO2 produced a 25% lower ratio of 16:1trans to 16:0 in PG compared with the ambient concentration. With good nutrient supply, growth at elevated CO2 did not significantly affect single seed weight, total seed mass, oil yield per seed, or the fatty acid profile of the seeds. This study has shown that elevated CO2 induced changes in leaf lipid composition in A. thaliana, whereas seed lipids were unaffected.
