Dispersion occurs in the characteristics of the transistors. The effective ingredient can be used in combination with a vector andor metabolite that is specific to the malignant cells. The trailing buoy is held in a release frame, the anchor is lowered to a desired height above a seabed, then the release mechanism is shifted and the anchor is permitted to free fall and penetrate into the seabed. The thermocouple connectors are already organized within the adapter so that each thermocouple is plugged into its proper location on the data logger. The integration time dynamic control apparatus may measure a motion of a depth image acquired from the depth camera, may determine whether the measured motion is greater than or equal to a reference value set in advance, and may control the integration time of the depth camera based on a result of the determination, thereby improving the accuracy of the depth image.
