A refueling method for supplying fuel to hydraulic fracturing equipment by installing a main fuel source at a fractionation operation, connecting the main fuel source to hydraulic fracturing equipment to provide downhole fluids to the well, and connecting at least one pressurization unit to the main fuel source. The lamp chamber is formed from a lamp body fixed to a vehicle body and a front cover that covers a front open portion thereof. When the bandgap reference circuit starts, the startup circuit slowly charges a capacitor using the voltage supply when the startup current is flowing. After the tool has been used, the tongue can be pushed out of the opening from outside, with plastic deformation, so that the tool can no longer be connected to the tool holder. The outer arm section extends to the other side of the attachment mechanism for supporting a threshing concave outside the housing when the support arm is attached to the housing. The invention relates in particular to texosomes and dexosomes, and their use for the vectorization and presentation of antigens in vitro or in vivo as well as in methods or compositions for the treatment of cancers and infectious, parasitic or autoimmune diseases in particular.
