Abstract: The present invention relates to a method for culturing microalgae, including: (a) immersing a photobioreactor including a culture container through which a culture solution but not microalgae passes into environmental water; and (b) supplying additional environmental water into the culture container. Through the present invention, it is expected that microalgae can be economically and efficiently mass cultured.

Abstract: A strut type suspension system of a vehicle has the advantages of reducing a diameter of a stabilizer bar and improving a braking stability by disposing the stabilizer bar and a steering gear box at a front side. The suspension system includes a stabilizer bar and a steering gear box is fixed on a sub frame, wherein the stabilizer bar is disposed at a middle front portion between an upper panel and a lower panel forming the sub frame.

Abstract: An upper arm for a vehicle suspension includes a main plate and a subsidiary plate. The main plate includes a first bush fitting at a first end of the main plate, configured to be attached to a wheel knuckle; second and third bush fittings, spaced apart from each other at a second end of the main plate and configured to be attached to a vehicle body; and two walls at first and second sides of the main plate. The main plate and the walls define an open cross-section along a substantial portion of the main plate. The subsidiary plate is attached to the second end of the main plate. The main plate, the walls, and the subsidiary plate define a closed cross-section at the second end of the main plate.

Abstract: A lower arm of a vehicle suspension includes a base defining: a knuckle assembly configured for a knuckle and ball joints to be coupled thereto, a front assembly configured to be coupled to a front side of a vehicle body, and a rear assembly configured to be coupled to a rear side of the vehicle body. The knuckle assembly, the front assembly, and the rear assembly define a plane. The front assembly includes a pipe member coupled to the base. A first cross-section of the base is defined by a first center part that curves below the plane defined by the assemblies, a first wall portion extending downward from the first center part, and an end portion extending inward from the first wall portion.
