Estimation of the efficiency of road construction machines in the design [PDF]

E3S Web of Conferences
The reasons for the decrease in the efficiency of road construction machines are fluctuations in speed and load, deviations of which from the optimal value in terms of efficiency and causes an increase in energy losses and a decrease in efficiency.

Delivery of DNA‐encoded vaccines and proteins in mice using cutaneous suction‐mediated transfection

FEBS Open Bio, EarlyView.
Cutaneous suction‐mediated transfection in mice for delivery of DNA‐encoded vaccines and proteins. A critical limitation of DNA vaccines and other therapeutics is transfection in vivo to produce the encoded antigens or therapeutic proteins. Cutaneous suction‐based methods have demonstrated effectiveness in many animal models and have been successfully ...
