A molten metal level measuring device in a continuous molten metal level measuring device uses temperature compensation. The device includes a cylindrical bobbin, a liquid level measuring unit helically wound around an outer surface of the bobbin, a circular inner cylinder in which the bobbin and the liquid level measuring part are located and which seals the bobbin and the liquid level measuring part from the outside and has the same axial direction as the bobbin, and a cylindrical protective tube in which the inner cylinder is located and which has the same axial direction as the bobbin and has one open end. Thermocouples extend axially in the space between the inner cylinder and the protective tube, and a control unit controls the liquid level measuring part to measure a liquid level of the molten metal based on the temperatures measured by the thermocouples.

An apparatus and method for monitoring a flow of liquid in a pipe are provided. The apparatus may include a temperature sensor attached to a pipe of a heat exchanger system to measure a temperature of the pipe, and a controller to determine whether a liquid is present in the pipe, based on a change in the measured temperature.

Disclosed herein is a decay heat removal system, including: a decay heat exchanger that absorbs decay heat generated by a nuclear reactor; a heat pipe heat exchanger that receives the decay heat from the decay heat exchanger through a sodium loop for heat removal and then discharges the decay heat to the outside; and a sodium-air heat exchanger that is connected to the heat pipe heat exchanger through the sodium loop and discharges the decay heat transferred thereto through the sodium loop to the outside. According to the decay heat removal system, a heat removal capability can be realized by the heat pipe heat exchanger at such a high temperature at which the safety of a nuclear reactor is under threat, and a cooling effect can be obtained through the sodium-air heat exchanger at a temperature lower than that temperature.

High protein content feed or synthetic steroides are used to elevate the efficiency of feed and promote pig growth. However, the steroids are not metabolized quickly but remain in the body for a long time and may have a detrimental influence on humans. The invention relates to a method for the production of porcine growth hormone which improves the growth of pigs and the efficiency of feed using a synthetic gene in yeast cells. It has been found that porcine growth hormone may be produced economically and in bulk in yeast by gene manipulation technology.

High protein content feed or hormonal steroids have been added to fish feed in order to elevate the efficiency of the feed. However, the steroids remain in the fish and may be detrimental to those who eat the fish. The invention relates to a method for the production of salmon growth hormone, which enhances the efficiency of the feed without the above side effects, using a synthetic gene in yeast or E. coli. It has been found that salmon growth hormone may be produced economically and in bulk in yeast or E. coli by gene manipulation technology.
