Abstract: The present invention provides infectious recombinant Hepatitis C Viruses (HCV), and vectors, cells and animals comprising the same. The present invention provides methods of producing infectious recombinant HCV, and their use in identifying anti-HCV therapeutic agents, as well as sequences of HCV associated with HCV pathogenesis.

Abstract: The invention concerns a mounting and anti-rotation device (mounting aid) (1) for roller tappets of a valve train of an internal combustion engine in which gas exchange valves are activated by roller tappets. The roller tappets comprising a substantially cylindrical tappet body are retained in receptions (7, 8) of the mounting aid (1) that is made of plastic. With the help of opposing parallel anti-rotation surfaces that are arranged symmetrically to the longitudinal axis of the roller tappet and are disposed on the end of the tappet body that is oriented away from a roller, the roller tappets are guided secured against rotation in the mounting aid during the operation of the internal combustion engine. This is achieved by the fact that the inner profile of the receptions (7, 8) is matched to the outer profile of the roller tappets.

Abstract: The present invention relates to a teosinte crossing barrier trait. Plants containing said trait exhibit the phenotype of cross-incompatiblity. The present invention also relates to new cross-incompatible plants, including inbred, hybrid, haploid, apomictic and/or genetically engineered plants, containing the teosinte crossing barrier trait and exhibiting commercially desirable characteristics.

Abstract: This invention provides the genes for indeterminate gametophyte1 (ig1), mutants of ig1, homologs of ig1, and orthologs of ig1, as well as the proteins encoded by these genes. This invention also provides compositions and methods which utilize these genes and proteins.

Abstract: A detector system that contains two inlet port coupled to a photoionization chamber. One inlet port allows for the introduction of a test sample. The test sample may contain contaminants, drugs, explosive, etc. that are to be detected. The other port allows for the simultaneous introduction of a standard sample. The standard sample can be used to calibrate and/or diagnose the detector system. Simultaneous introduction of the standard sample provides for real time calibration/diagnostics of the detector during detection of trace molecules in the test sample. The photoizonizer ionizes the samples which are then directed into a mass detector for detection of trace molecules. The detector system may also include inlet embodiments that allow for vaporization of liquid samples introduced to a low pressure photoionizer.

Abstract: In an internal combustion engine with a motor block (6) and a longitudinal extending anti-rotation guide (5), which includes receiving recesses situated at apportioned spatial distances, one from the other to receive valve tappets and is affixed in a receiving groove of the motor block (6). The guide (5) is constructed as an injection molded component with a one-piece, molded-on, elastically expanded or deformable clip, which engages in a complementary receiving contour on the motor block (6).

Abstract: Electromagnetic coils having rectilinear cross-section core elements and an armature bar having a rectilinear cross-section are described in a handheld tattoo apparatus. This results in increased vibrational smoothness as sensed by the tattoo artist.

Abstract: The invention is concerned with compositions comprising novel water-dispersible copolymers which contain at least one UVA light-absorbing monomer, one UVB light-absorbing monomer, one hydrophilic monomer, and optionally one hydrophobic monomer component. The UVA light-absorbing monomer absorbs at .lambda.max ultraviolet light in the 320-400 nm range. The UVB light-absorbing monomer absorbs at .lambda.max ultraviolet light in the 290-320 nm range. Because of the R.sub.3 group used in the invention, the copolymers used in the compositions of the invention permit higher loading of UV monomers than previously obtainable.
