A grip portion has a shape that conforms to a shape of the trekking staff and can include a strand of cord-like material. A light emitting device can be selectably controlled to emit either a constant light or a flashing light.

The present invention describes chemical protective enclosure comprising a waterproof outer surface comprising an impermeable portion and an air diffusive portion, and further comprising a chemically adsorptive material substantially adjacent the air diffusive portion, wherein there is sufficient diffusion of breathable air into the chemical protective enclosure to sustain life.

A device for holding objects that are attractive to the senses of animals, including a device for protecting a live catnip plant for use by a cat, the device in one form having a protective enclosure defining an interior to receive the object, such as the plant and plant supporting medium, the cage including a plurality of bars spaced apart to prevent or restrict access to the interior and direct contact with the object while allowing liquid, air, and light to pass through the bars to sustain the plant life and allowing the plant to grow through the bars to the exterior of the device for access by the cat. A watering cap in a top of the cage distributes water to the plant inside the enclosure. A cat toy, scratching surface, or platform or combination thereof may be incorporated into or associated with the enclosure.

The invention discloses a crucian carp feed capable of preventing and treating a branchia hyperemia disease and a preparation method of the crucian carp feed, and belongs to the technical field of preparation of the crucian carp feed. The crucian carp feed is prepared from the following main raw materials of trash fish powder, corn protein powder, soybean flour, rice bran, yellow rapeseed meal, wheat bran powder, bentonite, radix isatidis, croton fruits, heartleaf houttuynia herbs, garlic, pumpkin seeds, chinaberry bark, common andrographis herbs, common cnidium fruits, radix sophorae flavescentis, Chinese galls, macleaya cordata, akebia stems, cyrtomium rhizomes, dioscorea zingiberensis, trehalose, propolis and calcium dihydrogen phosphate. According to the crucian carp feed disclosed by the invention, the bentonite is added, so that the production efficiency of a granulator can be effectively improved; Chinese herbal medicine substances having effects of resisting bacteria and killing insects and a natural antibacterial agent are added, so that pathogenic bacteria and pests of the branchia hyperemia disease can be effectively prevented and treated; effective components in Chinese herbal medicine substances are extracted by an ethanol backwashing method, so that the extraction rate is high. The crucian carp feed disclosed by the invention is rich in nutrition, can be used for effectively preventing and treating the branchia hyperemia disease of crucian carps and reducing the breeding risk of the crucian carps, and is worth popularization and application.

The invention discloses a placental tissue preservation liquid and a preparation method thereof. The placental tissue preservation liquid includes glucose injection, a serum replacement, gentamicin, amphotericin, trehalose and heparin lithium. The preparation method of the placental tissue preservation liquid includes adding the serum replacement, gentamicin, amphotericin B, magnesium ascorbyl phosphate hydrate, trehalose and heparin lithium into the glucose injection, wherein final concentrations of the ingredients are 0.5-2%, 800 U / mL, 15-30 ug / mL, 0.25-0.5 mg / mL, 0.6-3 mg / mL, and 20-40 U / mL. The placental tissue preservation liquid has clear composition and balanced nutrition, has no evident toxic and side effects on cells, can well maintain activity of in-vitro placental cells, and iseffective in preventing contamination of exogenous microorganisms introduced in the acquisition and transport steps.

The present invention the manufacture of a membrane for gas and liquid separations in which a polymer layer is applied directly to a tricot fabric instead of the conventional cloth or glass or metal substrate.

An improved vehicle fuel system enables mixing of natural gas and a liquid fuel upstream of a combustion cylinder. According to some embodiments the system includes: a gas pressure vessel and associated gas pressurisation system to deliver natural gas at a desired pressure; a liquid fuel storage vessel and associated reservoir pump to deliver liquid fuel at a desired pressure; a mixing system configured to receive and mix the liquid fuel from the liquid fuel storage vessel and natural gas from the gas pressure vessel to produce a homogeneous fluid fuel mixture; and a common rail system connecting the mixing system to an engine that consumes the homogeneous fluid fuel.

The invention belongs to the field of cell biology and relates to a method and reagent for the separation and culture of neurons. The method and the reagent are used for solving problems in the prior art, the current in-vitro hippocampal neuron separation and culture methods are improved, and the problem that the proliferation and activity of cortex nerve cells during primary culture can not be maintained is solved. According to the method and the reagent, a relatively mature in-vitro cortex nerve cell culture method is established, the number of obtained nerve cells is sufficient, the growth status is relatively good, and a large number of high-activity cortex nerve cells can be separated from mammalian hippocampal tissue, so that the requirements for the primary culture of the cortex nerve cells are met, and the demands on experiments of cell biology during neuroscience research can be met.

The invention discloses a novel nutrient bakery food capable of replacing dinner, which is characterized by comprising the following components in percentage by weight: 20 to 40 percent of flour, 6 to 28 percent of isolated soy protein powder, 6 to 30 percent of fuctooligosaccharides, 6 to 30 percent of sorbitol, 0.6 to 1.2 percent of soda, and 5 to 20 percent of fermented cream. The novel nutrient bakery food can provide protein nutrients needed by daily body metabolism, and is easy to be digested and absorbed by human body and can balance dietary pattern; and by using fructooligosaccharides and sorbitol instead of sugar and grease highly-contained in the bakery food, the novel nutrient bakery food has low energy and sweetness, moderate texture, softness and crispness, and good quality, taste and chewiness. Moreover, the novel nutrient bakery food is convenient, nutrient, sanitary, economic and instant, not only solves the problem that certain people suffer nutritional deficiencies due to having no time to eat, but also eliminates the worry about obesity of people.

The invention discloses a whitening and freckle-removing cosmetic containing negundo chastetree fruit stem cells.
