Abstract: The invention belongs to the field of biotechnology, in particular, relates to peptide fragment, monoclonal antibody, colloidal gold test strip and detection method thereof used for detection of stichopus oligopeptide. Sequences of the peptide fragments are KIVPGVPD and GRDGDQGPV. After identification, the peptides KIVPGVPD and GRDGDQGPV are newly discovered oligopeptides, which are exclusive peptide fragments of Stichopus oligopeptide.

Abstract: A papermaking process includes, firstly, providing carboxylated cellulosic fibers with a carboxyl group content being in the range from 0.06 to 1.5 mmol/g. Then the carboxylated cellulosic fibers are employed to prepare mixing pulp including filler particles, wherein the content of the carboxylated cellulosic fibers in the mixing pulp is in the range from 40% to 100% by dry fiber weight of the mixing pulp. After that, paper is made employing the mixing pulp.

Abstract: A process for making pulp includes providing plant fiber raw material. The plant fiber raw material can be wood fiber or gramineae plant fiber. The plat fiber raw material is cooked to make a pulp. A TEMPO catalytic oxidation system is added to the pulp to oxidize the pulp fiber. The oxidized pulp fiber is then bleached.

Abstract: A modified filler composition used in papermaking is provided. The modified filler composition contains nanofibrillated cellulose having a carboxyl content of about 0.05 to about 1.5 mmol/g, and filler having positive charge.

Abstract: An illuminated bucket is a double-layered or walled carrier, with LED light, or other illuminated source, established between the layered inner and outer walls for the formed carrier. The circuitry for the LED lights includes a battery, and may further include a flasher that allows for blinking of the lights.

Abstract: An illuminated candy or other merchandise bucket or carrier is provided for use by children on Halloween, or other holidays. The structure of the bucket is a double-layered or walled carrier, with LED light, or other illuminated source, established between the layered inner and outer walls for the formed carrier. The carrier may look like a lantern from the outside, with a bucket structure upon its inside, so as to add to the convenience of its conveyance. When it is used at night, it provides a clear path illuminated for the child so as to avoid any accident or injury. Furthermore, the parent or others, such as a driver, will be able to see the lighted carrier, so as to avoid any accident.
