The present invention relates to oil gel compositions that include at least one non-aromatic ester oil and an anionic block copolymer of a mono alkenyl arene and a conjugated diene. The bone fixation body has a porous structure that includes a location at which the porous structure extends throughout the bone fixation body and through a center of the bone fixation body in a cross-sectional view of the bone fixation body. The size, number and arrangement of the perforations is selected such that ample airflow is provided and audibility of intake noise is minimized in conjunction with the corresponding tubes of the sound attenuation chamber. According to the comparison result, information indicating whether a previous reverse packet has been successfully received and power control information for controlling power of a reverse link is inserted and transmitted in at least one of a Medium Access Control channel and an OFDM symbol. Similar second control and generation units are also provided mutatis mutandis. The equation based solution of the melt curve is then used to determine the first derivative and peak height.
