Abstract: Provided herein is a road stud used to recognize the central line or lanes of a road. The road stud is configured in the form of a screw to be securely fixed to and buried in a road. The road stud includes a self generator to light up an illuminating element all the time irrespective of the existence and absence of sunshine or illumination, humidity and temperature sensors for sensing the condition of the road to emit different color lights in response to various conditions of the road, and a communication unit for transmitting/receiving information about the condition of the road to/from cars. The road stud has strong shock-resistance and smoothly emit light irrespective of existence or absence of external power supply or the quantity of sunshine.

Abstract: Disclosed herein is a method for separating and purifying .alpha.-linolenic acid (ALA) from ALA-containing fatty acid mixtures by using a column chromatography, comprises the steps of:packing a column with silver nitrate(AgNO.sub.3)-impregnated silica gel as a stationary phase;passing the ALA-containing fatty acid mixtures through the column to adsorb the fatty acids to the stationary phase in the form of Ag.sup.+ -complexes;eluting the fatty acids with acetone-hexane mixtures; andcollecting the fractions containing ALA having a purity of more than 95%.
