The paper deals with the research devoted to characteristics of high tech business development in Russia. Companies’ performance indicators have been analyzed with the help of regression analysis and author’s scheme of leadership stability and sustainability assessment. Data provided by Russia’s Fast Growing High-Tech Companies’ National Rating (TechUp) during 2012-2016 were used. The results have revealed that the high tech sector is characterized by high level of uncertainty. Limited number of regions and sectors which form the basis for high tech business have been defined. Relationship between innovation activity’s indicators and export potential is determined.

The expensive nature of currently used materials in the soft robotic industry demands the consideration of alternative materials for fabrication. This work investigates the performance of RTV-2 grade silicone rubber for fabrication of a soft actuator. Initially, a cylindrical actuator is fabricated using this material and its performance is experimentally assessed for different pressures. Further, parametric variations of the effect of wall thickness and inflation pressure are studied by numerical methods. Results show that, both wall thickness and inflation pressure are influential parameters which affect the elongation behaviour of the actuator. Thin (1.5 mm) sectioned actuators produced 76.97% more elongation compared to thick sectioned, but the stress induced is 89.61 % higher. Whereas, the thick sectioned actuator (6 mm) showed a higher load transmitting capability. With change in wall thickness from 1.5 mm to 6 mm, the elongation is reduced by 76.97 %, 38.35 %, 21.05 % and 11.43 % at pressure 100 kPa, 75 kPa, 50 kPa and 25 kPa respectively. The induced stress is also found reduced by 89.61 %, 86.66 %, 84.46 % and 68.68 % at these pressures. The average load carrying capacity of the actuator is found to be directly proportional to its wall thickness and inflation pressure.

Abstract Project 70 and Project 7000 Type 203 stainless steels are alternative materials to AISI Type 303, resulfurized stainless steel having improved machinability. High manganese and copper are substituted for some nickel resulting in a stable austenitic structure having low magnetic permeability. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-505. Producer or source: Carpenter.

Mandated by the Swiss Forestry Agency, a group of internationally recognised experts drew up a sustainability assessment of Swiss forest policy. In this paper, the author, himself a member of the expert panel, presents the main results of this study. The strong protection regime of forests, for instance, is seen as one of the strengths of Swiss forest policy, whereas the lack of economic efficiency as well as the lack of clear policy goals with corresponding evaluation criteria have been identified as areas of concern.

International Experts

A group of international experts evaluated whether the aims and instruments of Swiss forest policy are suitable for the promotion of sustainable forest management based on the pan-European criteria. Approach and main results are presented as well as the method developed for the definition of sustainability indicators as an instrument for the evaluation of sectoral policies and the possibility of a transfer of methods and indicators on an international level.
