The invention relates to a sunflower seed, comprising a sunflower oil having an increased stearic acid content as compared to wild type seeds, obtainable by treating parent seeds with a mutagenic agent during a period of time and in a concentration sufficient to induce one or more mutations in the genetic trait involved in stearic acid biosynthesis resulting in an increased production of stearic acid, germinating the treated seeds and culturing progeny plants therefrom, collecting and analyzing progeny seeds, selecting seeds that have acquired the desirable genetic trait and optionally repeating the cycle of germination, culturing and collection of seeds. Preferably the seeds comprise an oil having a stearic acid content of between 19.1 and 35% by weight related to the total amount of fatty acids in the oil, and are obtainable by treating the parent seeds with an alkylating agent, such as ethyl methane sulfonate in water, or with sodium azide in water. The invention further relates to sunflower oil obtainable by extracting the sunflower seeds, to a method for preparing sunflower seeds having an increased stearic acid content as compared to wild type seeds, a method for preparing a sunflower oil having an increased stearic acid content sunflower plants produced from the seeds and the use of the sunflower oil in various products.
摘要:
Structures (1, 21, 41, 71, 161) of electrochemical cells and electrochemical cell components employ a switch-like article (10, 26, 48, 63, 65, 68, 76, 166) comprised of an electrically conducting material that becomes nonconductive or semiconductive outside of a discrete voltage window. Said switch-like article serves as a reversible, self-regulating electrochemical switch at boundary voltages, thereby protecting the cell against over-charge and or over-discharge, and can be employed in a variety of configurations to provide self-regulating cell architectures. Cell assemblies that include said switch-like articles may themselves serve an auxiliary function as switches for other cells placed in series or parallel, and for external circuits.

The invention relates to a novel microalga species and to the use thereof for animal and/or human consumption and in the production of carotenoids. A novel strain of Scenedesmus has been isolated at the Las Palmerillas experimental station, Cajamar, identified as microorganisms that had not been previously registered by the University of Gottinghem and deposited within the Culture Collection of Alagae and Protozoa (CCAP) as Scenedesmus almeriensis. The novel strain, which can be used for animal and/or human consumption, produces large quantities of carotenoids, particularly lutein and beta-carotene. Scenedesmus almeriensis grows adequately in a wide range of temperatures from 10° C. to 40° C. at a pH of between 7 and 9.5 and can tolerate high concentrations of copper, up to 1 mg/L. The microalgal strain is grown in a 4000 L photobioreactor, into which the culture is inserted mechanically, and produces less than 4 mg of lutein per gram of dry material. Said strain is suitable for the production of carotenoids that can be used in the treatment of ocular macular disorders.

The invention relates to plant seeds that contain an oil having an oleic acid content of more than 40 wt % and a stearic acid content of more than 12 wt % based on the total fatty acid content of said oil, and wherein a maximum of 10 wt % of the fatty acid groups in the sn-2 position of the TAG molecules constituting the oil are saturated fatty acid groups. The invention also relates to plants that can be grown from the seeds, oil that can be extracted from the seeds, and to methods for obtaining the seeds, plants and oil.

An energy storage system (10) including a first energy storage device (12), such as a secondary or rechargeable battery, and a second energy storage device (14), such as an electrochemical capacitor. The electrochemical capacitor provides intermittent energy bursts to satisfy the power requires of, for example, pulsed power communication devices. Such devices typically require power pulses in excess of those which conventional battery cells can easily provide for numerous cycles. The system (10) further includes circuitry (16) for coupling the capacitor (14) to a load in response to changes in the battery (12).

This invention advances the related state-of-the-art by eliminating the physical EO window used by electro-optical imaging infrared seekers for tactical missiles and high-altitude endo-atmospheric interceptors, widely employed in integrated defense systems. This invention increases the probability of intercepting exo-atmospheric ballistic warheads by exo-atmospheric interceptors, and eliminates the existing altitude “gap” of interception, as well as the geographical limitations posed by the mesospheric Noctilucent Clouds. The problem of protecting an imaging EO sensor from aeroheating is solved in this invention by a special purpose device which is enabled immediately after the nose cone ejection event. The role of said device is to augment the sensor fixed sunshade and cavity lengths in the forward direction, and by doing so, the resulting new cavity enables the optimal injection of an optically inert gas into the new extended cavity in front of the sensor, thus effectively blocking the entry of the compressed hot air into the sensor cavity, while simultaneously avoiding any adverse effects of inducing flow instabilities in the flow as well as the disturbance of the injected gas flow on sensor structures. Having a greater length for the hot gas to penetrate, eliminates also the penetration of suspended particles in oncoming air stream.
