Articles and films are provided from ethylene-based polymers made using a metallocene catalyst system. Biaxial orientation dramatically improves clarity, stiffness, dart drop impact, puncture resistance, and shrink. Tensile strength at yield and ultimate tensile are also improved. Film stiffness, as measured by secant modulus, is increased by 300 % over an unoriented film of the same ethylene poly...

A maximum value of each block after orthogonal transformation is detected, and an output word length after orthogonal transformation is controlled in accordance with the maximum value thus detected. In addition, a plurality of tables each having a plurality of quantizers combinedly used are prepared and a table is selected in accordance with the maximum value of each block, thereby selecting the o...

A method of mapping areas of a slide includes the steps of selectively illuminating the slide from a first light source oriented generally obliquely to the surface of the slide, obtaining a first image of the slide illuminated by the first light source, selectively illuminated the slide from a second light source providing generally scattered light, obtaining an image of said second image illumina...

A process for the catalyzed isomerization of a Z-isomer of a vitamin A compound or of a mixture of several of such isomers into a mixture of the corresponding all-E- and 13-Z-isomers of this vitamin A compound comprises using nitrogen monoxide or a gas mixture containing nitrogen monoxide as the isomerization catalyst. Moreover, the isomerization process is conveniently effected in a polar or apol...

Treatment plant consists of a large annular tank (8), e.g. 10-18 m in diameter and 5-8 m high, containing between 4000 and 18000 m<3> of liquid. The tank has \-2 aeration zones (9) which alternate with anoxia zones (10), with the aeration zones containing perforated aeration tubes (11) and supports (12). The supports are shaped to limit their disturbance to the flow of liquid in the tank, which is...

Production of recombinant adenovirus (A) comprises: (a) introducing viral DNA into a culture of packaging cells, and (b) harvesting (A) produced after their release into the supernatant.
