Also provided are methods of preparation of the oil in silicone and the oil in silicone/water in silicone dual emulsions, compositions that employ these emulsions, and methods of using the compositions to repel insects from skin and protect skin from exposure to the sun.

Disclosed is a hybrid wind-solar energy device comprising: a) a wind-capture assembly comprising: i) one or more wind sails evenly distributed circumferentially around a central axis thereof; and ii) a solar-energy capture means on an outer surface of the wind-capture assembly; and c) a turbine assembly comprising an anchoring base, an electrical generator and an output shaft; the wind-capture assembly rotatably mounted on the output shaft and coupled thereto; the hybrid wind-solar energy device configured to convert energy harnessed by the wind capture assembly to electrical energy, wherein: interaction of the one or more wind sails with wind induces rotation of the wind-capture assembly and turbine assembly around the central axis; and the outer surface of the wind capture assembly is directly exposed to sunlight throughout daylight hours.

A degradable plastic film for use as an agricultural mulch film comprises two longitudinal bands each adjacent to a respective longitudinal edge of the film, and a middle section between the bands. The bands and middle section contain degradants. In use, the bands along the edges of the mulch film are buried in the soil and the middle section is exposed to sunlight. By reason of different degradants in the bands and middle section respectively, or different levels of the same degradants, the entire film degrades by the time of the next cycle of cultivation. The film is produced by means of extrusion from two extruders through one circular die which has a die opening with one segment which receives resin with one degradant and another segment which receives resin with a second degradant. The extruded cylindrical film is blown and then slit longitudinally.

The invention relates to a bamboo rhizome cultivating method, which belongs to the technical field of bamboo forest cultivation. According to the invention, the bamboo rhizome cultivating method comprises the following steps of: (1) piling up ridge troughs: selecting a field with hard ground as a cultivating land and arranging ridge troughs on the cultivating land; (2) selecting and digging mother bamboos: shoveling the mother bamboos along the peripheral edges of the mother bamboos so as to form soil balls with the mother bamboos; (3) planting the mother bamboos: arranging the selected and dug mother bamboos in the ridge troughs and adding soils to the ridge troughs so as to pile up the ridge troughs; (4) inducing bamboo rhizomes: after growths of the bamboo rhizomes are recovered, covering 8-12 cm soils in furrows formed in a space between the adjacent ridge troughs, keeping the soils in a wet state, and inducing new bamboo rhizomes growing from the mother bamboos to grow into the furrows; and (5) treating and collecting the bamboo rhizomes: exposing the new bamboo rhizomes to sunlight so as to treat the bamboo rhizomes, and then collecting aged new bamboo rhizomes. The bamboo rhizome obtained by the bamboo rhizome cultivating method provided by the invention has the advantages of high yield, large toughness and long service life.

The invention discloses a novel photothermal salt sun-drying accelerating method. The novel photothermal salt sun-drying accelerating method comprises the following steps of enabling a pumping deviceto inject the seawater into a salt tank; enabling one end of a hydrophilic material to extend into the seawater of the salt tank, and be in full contact with the seawater; enabling the other end of the hydrophilic material to be in full contact with an optical absorbing material, and exposing the optical absorbing material under the sun; injecting a heat insulation material between the optical absorbing material and the seawater; adjusting the contact area between the hydrophilic material and the seawater, and the hydrophility or width or thickness of a hydrophilic device, so as to control thewater absorbing rate of the hydrophilic material; drying the salt crystal at the bottom part of the salt tank under the sun. The invention also discloses a novel photothermal salt sun-drying accelerating device. The novel photothermal salt sun-drying accelerating method has the advantages that the salt-making seawater can be quickly evaporated, the salt sun-drying cycle is greatly shortened, andthe production efficiency of the salt sun-drying process is obviously improved.

A method for treating a region of skin. An amount of at least one photolabile compound or a compound converted into a photolabile compound when present in the skin is applied to the region of skin. The photolabile compound generates a biologically active agent when in the skin and the skin exposed to sunlight. The applied compound is allowed to penetrate into the skin; and the region of skin is exposed to sunlight so as to generate the biologically active agent in the skin.

The invention relates to a fishing-light integrated pond circulating water aquaculture system, comprising a culture unit, a water purification unit, a photovoltaic power generation device and a water pushing device for promoting the flow of a water body. The water outlet of the aquaculture unit is connected with the water inlet of the water purification unit, The water outlet of the water purification unit is communicated with the water inlet of the breeding unit, and the water pushing device is arranged in the water purification unit; the photovoltaic power generation device includes a plurality of photovoltaic panels, an inverter connected to the photovoltaic panels, and a device connected to the inverter. The electric device and the power distribution device supply power to the water pushing device, and the photovoltaic panel is arranged above the water purification unit. By combining photovoltaic power generation with an engineered circulating aquaculture system, the invention improves the utilization rate of the water surface of the pond, thereby improving the breeding efficiency of the farmers; by only setting the photovoltaic panels in the water purification unit, and exposing the breeding unit to the sun, electricity is generated. At the same time, it will not affect the productivity of the pond and ensure the breeding efficiency.

A covering component for protecting outer surfaces of buildings from atmospheric agents comprises a metal sheet (7), an insulating mass (8) arranged below said sheet (7), and heat exchanging means (7–9, 11, 12) comprising at least a passage channel (7B), the latter being an integral part of the component and being designed to be part of a solar energy heating system for a heat conveying fluid.
