Biomass production and oil productivity in microalgae culture are the most important key factors for algal biodiesel production. However, proper culture condition for the biomass production of microalgae is different from that for the oil production of microalgae. A study on the biomass production of Tetraselmis suecica using various light intensities and(More)
This paper presents micropositioning system using feedback of multiple magnification images from CCD cameras mounted on an optical microscope. In order to guarantee of the accurate micropositioning to micro assembly system, high precise sensors are required. But many kinds of sensors, which are used in macro world, have insufficient resolution and size. The(More)
To represent complex structure, graph data is widely used in diverse applications. Among various techniques to extract meaningful information in graph data, graph clustering is an important task for the discovery of an underlying graph structure. However, the volume of graph data becomes large and increases fast recently as well as traditional clustering(More)
PURPOSE The purpose of this study was to evaluate the quadriceps and hamstring muscle strength and hamstring-to-quadriceps (HQ) ratio, as well as the relationships of these parameters with dynamic balance, in patients with anterior cruciate ligament (ACL) rupture. MATERIALS AND METHODS We compared 25 patients diagnosed with chronic unilateral ACL tears(More)
PURPOSE This study was designed to compare the preoperative strengths and endurances of the quadriceps and hamstring muscles in patients with anterior cruciate ligament (ACL) versus posterior cruciate ligament (PCL) tears. METHODS Quadriceps and hamstring muscle strength and endurance were compared between 20 prospectively enrolled patients with isolated(More)
