The purpose of this paper is to create and test an idea management sequence framework to reinvent or redefine the value proposition. Idea management with sequencing activities must be considered as a systematic managerial process and should not be confused with the occasional result of an individual with a design thinking mindset. This paper suggests a new approach-a systematic, 4-step idea management sequence to redefine or reinvent value proposition in a business model, which was validated through an action-based research method involving 20 managers from practice by applying the proposed framework.

We report experimental results for the changes in conductivity of single-wall carbon nanotube bundles when irradiated by (60)Co γ-rays in various environments. In the current study the samples investigated were irradiated in hermetic cells, either evacuated (0.1 Pa) or filled with hydrogen or deuterium at atmospheric pressure.

Homogeneous nanostructured Si3N4-TiN composite powder was obtained by nitration of a TiSi2 powder precursor in a nitrogen flow. Mechanoactivation of titanium disilicide increases the nitration rate and reduces the temperature of formation of the Si3N4 and TiN. The properties of hot pressing (HP) and spark plasma sintering (SPS) of the nanostructured Si3N4-TiN composite with Y2O3 and Al2O3 additives have been studied.

We followed 70 patients, aged 1 to 11 years: 30 children had primary celiac enzymopathy (CE), the other had secondary fermentopathy represented by the celiac syndrome in 20 subjects and by the disaccharidase insufficiency syndrome (DIS) in another 30 subjects. Distinct disorders were registered in the liver and hepatobiliary system in children with enzymopathy variations of the small intestine (ESI). Despite a general identity of the clinical signs observed in ESI, the ultrasound signs of the fat hepatosis were more often the case in the celiac disease rather than in the celiac syndrome.
