Fixation of soft tissue to bone is performed using a flexible material with a portion having an expanded footprint to provide a cushion or tissue protector between the flexible strand and the tissue to be attached. The lithium secondary battery using the electrolyte for a lithium secondary battery according to the present invention has excellent high-temperature stability, high-temperature capacity recovery rate, low-temperature discharge capacity, and life cycle characteristics. Ca2 dispersed in a wax matrix are used in fracturing operations to break hydrocarbon liquids gelled with salts of alkyl phosphate esters. The legs are sufficiently elongated to provide good balance in their extended position.
