This tropical cyclone weakening system involves, firstly, injecting cold water drawn from depths of at least 200 meters into the surface of seas and oceans, and secondly, injecting this water beneath a layer of sargassum seaweed to limit the warming of this deep water. This system operates primarily in areas of the North Atlantic where both the major cyclone tracks and sargassum beds are located. The aim is also to capture the sargassum at sea so that it no longer washes ashore. Furthermore, the system allows for continuous electricity production through its ocean thermal energy conversion (OTEC) plants and includes a sargassum collection system to utilize the harvested sargassum.

A C-terminal truncated alginate lyase and its application. This invention belongs to the fields of bioengineering, genetic engineering, and enzyme engineering, and relates to a C-terminal truncated alginate lyase TY2 designed with molecular docking assistance, its encoding gene, recombinant vector, strain, and its application in the preparation of low-polymerization degree alginate oligosaccharides. Using wild-type MhAly6 as the parent, the truncation boundary was determined through structural prediction and molecular docking. A portion of the linker peptide was retained, and the C-terminal GH28 family domain was deleted to obtain the truncated form TY2. TY2 has approximately twice the specific activity of the wild-type enzyme, and even higher residual activity after incubation at 45°C for 1 hour, achieving a synergistic improvement in catalytic activity and thermal stability. + The relative enzyme activity reached 4.3 times that of the control group, which can degrade pretreated Sargassum powder. The product is mainly ΔDP2–ΔDP4 low-polymerization brown algae oligosaccharides, which are suitable for related enzymatic degradation and oligosaccharide preparation.

To provide an expression inhibitor of a nerve elongation factor. Another object of the present invention is to provide an itching inhibitor and a skin / scalp cosmetic containing an expression inhibitor of a nerve elongation factor.SOLUTION: As a result of intensive studies to solve the above problems, the present inventors have found that the expression of NGF can be suppressed by a combination of a specific seaweed-derived component and a specific mushroom component or a specific natto component, an excellent effect of suppressing itching can be obtained, and an effect of improving skin and scalp conditions by suppressing NGF expression can be obtained, thereby completing the present invention. That is, the present invention provides an agent for suppressing the expression of a neural elongation factor, comprising (i) an ingredient extracted from a marine alga belonging to the family Sargassum or the family Alaria crassifolia, and (ii) at least one ingredient selected from (A) an ingredient cultured or extracted from a mushroom belonging to the family Agaricales and (ii) an ingredient extracted from natto. The present invention also provides an itching inhibitor and a skin / scalp cosmetic containing the expression inhibitor of the nerve elongation factor.SELECTED DRAWING: None

The invention relates to the related technical field of ocean engineering, in particular to a sea area floating bed structure for gulfweed cultivation, which comprises a floating bed, one side surface of the floating bed is provided with a connecting hole, and the inner side surface of the connecting hole is fixedly connected with a connecting column. According to the sea area floating bed structure for gulfweed cultivation, the pull ropes made of polypropylene can swing along with the spring pieces, concentrated stress is converted into dispersed flexible stress, the situation that a clamping part is abraded due to rigid friction is avoided, the circular holes and the pull ropes are designed in a size matched mode, deviation of the pull ropes is limited, space is reserved for movement of the pull ropes, and the service life of the pull ropes is prolonged. The spring piece is made of 316 stainless steel, sealing protection of double sealing rings is matched, invasion of seawater and sediment can be effectively blocked, stable operation of the elastic adjusting function is ensured, transverse storm impact and longitudinal tide traction can be effectively eliminated by means of the stretching and compression deformation capacity of the spring piece, and the buffering effect is improved. And the floating bed group can still keep a complete structure under continuous stormy waves.

A module for retrofitting a vessel for collecting floating biomass has a telescopic beam that spans the width of the vessel and connects to the aft ends of booms resting on the gunwale. The telescopic beam extends beyond both gunwales, allowing external net supports to be attached to it. The nets are secured and held open by net forks. The nets are at least partially submerged and fill with sargassum as the vessel moves forward. Longitudinal drag forces are resisted by chains connecting the booms to the bow. Torsion around the telescopic beam is resisted by prestressed straps that pass under the vessel and over the aft ends of the booms, extending forward to minimize strap tension and reaction force against the gunwale.The horizontal moments in the outer portions of the telescopic beam are absorbed by the inner portion of the telescopic beam.

The useful solution refers to a process for producing instant seasoning from fermented Sargassum quinhonense seaweed. This process involves treating the seaweed with soda, then fermenting it with a mixture of Lactobacillus plantarum, Lactobacillus pentosus, and Lactobacillus farciminis bacteria. The resulting mixture is then combined with spices and dried. This dried fermented Sargassum seaweed product is then mixed with food additives to create an instant seasoning. The instant seasoning produced using this solution has a distinctive flavor and can be used directly with rice as a supplementary food, or sprinkled directly onto rice.
