Methods and systems are disclosed for the hydrolysis of mixed biomass. To make such a guide easier to handle, easier to store and easier to install, the guide is designed in multiple parts, a first guide part being provided with a central lock device and designed as a locking means for a second guide part which is equipped with a locking stop. A second series of spit-wipe operations is then performed. Whereby, the intensity of the resulting vibration is reduced. The method of cementing may comprise introducing a cement composition comprising a hydraulic cement, nano-clay, and water into a subterranean formation. The first and second electronic components are moved in directions, in which a first point and a second point approach each other, and along the first and second Y axes by an approximated distance between the first and second points.
