The invention relates to an anti-ant large-core-number fiber ribbon cable comprising a cable core and an outer sheath. The cable core includes loose tubes; and fiber ribbons are sleeved inside the loose tubes. The outer sheath is an outer nylon sheath; and a non-metallic reinforcement layer is arranged between the outer sheath and the cable core. According to the anti-ant large-core-number fiber ribbon cable provided by the invention, with the outer nylon sheath, ants can not bite the sheath, so that the damages on the optical cable by ant biting in a pipe at an area with a serious anti problem are prevented, the normal state of the cable is ensured, and the application region of the cable is extended. The cable based on a simple and reasonable structure has advantages of small cable diameter, high fiber density, large fiber capacity, and low duty ratio and can be laid in a pipe conveniently; and the bending performance is good. During branched connection, 4 to 24 fibers can be melted once, so that the construction time is saved and the manpower cost is lowered, and the construction efficiency is improved. On the basis of the full drying type dielectric structure, branched connection is realized conveniently and usage becomes convenient.

Methods, compositions, and systems for steeping, propagation and fermentation, particularly large-scale operations for production of starch and ethanol and fermentation product streams are provided. Addition of mycotoxin mitigating enzymes or microorganisms expressing mycotoxin mitigating enzymes to steeping, propagation, and / or fermentation tanks, and / or to post-fermentation product streams, mitigates mycotoxin levels in fermentation co-products obtained from mycotoxin contaminated feedstocks.

The invention discloses a preparation method of a high-yield camellia oleifera shell pulp. The preparation method of the high-yield camellia oleifera shell pulp specifically comprises the steps of mechanical grinding, pre-impregnation, mechanical disc grinding treatment, washing, defibering and screening. The preparation method prepares the high-yield camellia oleifera shell pulp through a chemical and mechanical method; the prepared high-yield camellia oleifera shell pulp has the advantages of being high in yield, good in pulping performance and drainability and the like and can be applied tothe fields of paper-based packaging, molding and decorating materials and the like, thereby to some extent easing the stress brought about by shortage in papermaking fiber resources. Besides, a largenumber of waste camellia oleifera shells are applied to the fields of pulping and papermaking to achieve efficient and high-value application of agricultural waste.

The invention discloses a cisatracurium besilate content testing method which comprises the following steps: respectively weighing a test substance and a reference substance in a measuring flask, adding hydrochloric acid for dissolving and metering a volume to a scale, shaking up to prepare a corresponding solution, finally, measuring the solution according to an ultraviolet-visible spectrophotometry, measuring absorbance at a place of a maximum adsorption wavelength of 280nm, and calculating the content of cisatracurium besilate according to an anhydrous substance. According to the cisatracurium besilate content testing method, the solution is simply and conveniently prepared, no organic solvent is used, and the pollution to the environment and the harm to a human body are small. The cisatracurium besilate content testing method is higher in testing speed, and the time of testing each batch of products in average only needs 30 min. A place of a maximum adsorption wavelength of 280 nm is selected, so that the testing accuracy is ensured. The cost of a reagent used in a process of checking each batch of samples does not exceed 20 yuan; the testing cost of each batch of samples by adopting a high-performance liquid chromatography method is not less than 200 yuan, so that the cost of enterprises is greatly lowered.
