The paper deals with the problem of a huge gap between knowledge creation and impact on economy, which is relevant for Russia. A possible solution can be found by improving tools to support commercialization research results growth R&D-intensive companies. set such seen as favorable mechanism turn into innovation. main idea article, based system approach, puts adoption strategic decisions b...
The restriction-modification system is a toxin-antitoxin mechanism of bacterial cells to resist phage attacks. High efficiency comes at a price of high maintenance costs: (1) a host cell dies whenever it loses restriction-modification genes and (2) whenever a plasmid with restriction-modification genes enters a naïve cell, modification enzyme (methylase) has to be expressed prior to the synthes...
This paper presents design modification to the existing standard wheelchair by incorporating an improved propulsion system and also braking and tilting systems that allow its full control with only one hand. The proposed design has the propulsion system with a chain drive powered through a four-bar linkage driven by the main handle. The desired direction of motion is obtained by moving the leve...
The rational design of better electrocatalysts for the oxidation C1–C2 organic molecules requires detailed knowledge their mechanism. Pt single crystals are powerful tools to study, in a simple way, surface structure effect on different reaction pathways. Here, mechanism these is compared so that gained with simpler transferred analysis more complex ones. goal strategies platinum electrodes imp...
