Provided are an oleaginous microorganism disruption process using a supersonic disperser and a method for producing bio-oil using the same. The method for producing bio-oil according to the present invention induces a cell disruption of oleaginous microorganisms without a separate drying process, thereby providing a method for continuously producing bio-oil in an economical and simple manner. In addition, the method of the present invention induces a cell disruption of oleaginous microorganisms without a heating process, thereby producing bio-oil without a change in physical properties due to the heat.

Provided herein are microalgae of a Thraustochytrid and a method for preparing bio-oil using the same, and more particularly,sp. LA3 (KCTC12685BP) having bio-oil producibility, and a method of preparing bio-oil, particularly bio-oil having a content of omega-3 unsaturated fatty acids of 30% by weight or more based on total fatty acids, characterized by culturing the microalgae. The microalgaesp. LA3 (KCTC12685BP) described herein has a rapid sugar consumption rate when being cultured using glucose as a carbon source, has a high oil content, allows cells to be cultured at a high concentration, and allows oil to be obtained in high productivity and a high yield, and thus, may produce bio-oil more economically and environmentally friendly.

The present disclosure relates to an apparatus for curing spinal stenosis which is an abnormal narrowing of the spinal canal between spinous processes, more particularly, to an apparatus of fixing spinous processes which can prevent the narrowing or widening of the spinal canal between spinous processes along the motion of the spine so as to enhance spinal stabilization. The apparatus of fixing the spinous processes includes a spacer having at least predetermined portion inserted between spinous processes of two neighboring vertebrae to support the spinous processes so as to prevent narrowing of the spinous processes which is generated by spinal bending; and a clip provided to cover an outer surface of the spinous processes of the two neighboring vertebrae to prevent widening of a distance between the spinous processes generated by the spinal bending.

Apparatus of fixing spinous processes

Disclosed is a method of manufacturing high-quality naphthenic base oil by subjecting, as a feedstock, light cycle oil (LCO) and slurry oil (SLO) obtained through fluidized catalytic cracking (FCC) to hydrotreating and dewaxing.

Process for manufacturing naphthenic base oils from effluences of fluidized catalytic cracking unit

A method of manufacturing high-quality naphthenic base oils comprising a high aromatic content and a large amount of impurities with a boiling point higher than that of gasoline. High-quality naphthenic base oil may be manufactured from light cycle oil (LCO) and slurry oil (SLO), which are inexpensive, and have a high aromatic content, a large amount of impurities, and which are effluents of a fluidized catalytic cracking (FCC) unit. The method also relates to the pretreatment process of a feedstock, where the amounts of impurities (sulfur, nitrogen, polynuclear aromatic compounds and various metals components) in the feedstock are reduced.

Process for manufacturing high quality naphthenic base oils

The present invention relates to cosmetic compositions containing at least one polyethoxylated vitamin E species, which may be prepared by reacting a vitamin E with ethylene oxide, and exhibit an excellent cell protecting activity in the living body. The cosmetic compositions in the form of a skin-care, hair-care, lip-care and make-up cosmetic composition, which contain at least one polyethoxylated vitamin E species in an amount of 0.01 to 50% by weight, provide a protection against harmful oxygen species, show a moisture retention ability, and increase the tensile strength of hair, and substantivity and durability of the cosmetic compositions, when applied to the skin or hair.

Cosmetic compositions containing a polyethoxylated vitamin E

A hair color rinse composition that simultaneously dyes and conditions hair which comprises a tinctorial amount of one or more acidic dyes, from about 0.01 to 0.5 parts by weight based on the total weight of the composition of one or more halogenated fluorescein dyes and from about 1.0 to 20.0 parts by weight based on the total weight of the composition of a disodium dimethicone copolyol sulfosuccinate is disclosed.

Hair color rinse composition containing haloginated fluorescein dyes

A process for preparing a transparent cosmetic material having a moisturizing effect in which lactic acid and casein hydrolysate formation are carried out simultaneously in skim milk by lactic acid bacteria and proteases and, subsequently, sterilization of the lactic acid bacteria and inactivation of the proteolytic enzyme are carried out simultaneously.
