Abstract: A fuel tank includes a canister and a fuel control valve arranged in an expanding room. The canister has two guiding pipes communicated respectively with an entrance of an engine and environment. The fuel control valve is communicated with the expanding room. A double-lane valve is arranged between the canister and the fuel control valve. The double-lane valve has an entrance communicated with the fuel control valve, an exit communicated with the canister, a first valve and a second valve arranged between the entrance and the exit. The second valve withstands a spring and is arranged on the first valve. The first valve can detect an expending press produced by volatilized fuel gas to control whether the fuel gas enter into the entrance of the engine. The second valve can detects a vacuum press of the fuel tank to control whether air enter into the fuel tank.

Abstract: A first electrophoretic medium comprises an electrically charged particle suspended in a suspending fluid, the particle having a polymeric shell having repeating units derived from at least one monomer the homopolymer of which is incompatible with the suspending fluid. A second, similar electrophoretic medium comprises a suspending fluid, and first and second types of electrically charged particle suspended in the suspending fluid, the two types of particle having differing optical characteristics but both having polymeric shells. The polymeric shells are arranged such that homoaggregation of the two types of particles is thermodynamically favored over heteroaggregation.

Abstract: Methods of increasing the amount of polyunsaturated fatty acids (PUFAs) in the total lipid fraction and in the oil fraction of PUFA-producing, oleaginous eukaryotes, accomplished by modifying the activity of peroxisome biogenesis factor (Pex) proteins. Disruptions of a chromosomal Pex3 gene, Pex10p gene or Pex16p gene in a PUFA-producing, oleaginous eukaryotic strain resulted in an increased amount of PUFAs, as a percent of total fatty acids and as a percent of dry cell weight, in the total lipid fraction and in the oil fraction of the strain, as compared to the parental strain whose native Pex protein was not disrupted.

Abstract: A process of in vivo labeling and identifying recombinantly produced peptides or proteins within an unpermeabilized prokaryotic host cell. Recombinant prokaryotic cells expressing a fusion peptide comprising at least one tetracysteine tag were labeled in vivo using a biarsenical labeling reagent. A fluorescent activated cell sorter was used to identify and select subpopulations of fluorescent cells wherein the amount of fusion peptide in the cell was proportional to the amount of fluorescence detected.

Abstract: A material useful as a substitute component for a modified single phase system is selected. The substitute component exhibits a sigma profile that produces a selected property of the modified single phase system having a predetermined desired value. The substitute component is determined by the steps of: mutating the sigma profile of a component of an initial system; computing the value of a selected property of a modified system containing a candidate substitute component having the mutated sigma profile; comparing the value of the selected property of the modified system to the predetermined desired value; accepting or discarding the mutation based upon a predetermined acceptance standard; and repeating the steps for either a predetermined number of times or until the value of the selected property of the modified system meets the predetermined desired value.
