The invention provides vectors adapted for use in transferring into tissue or cells of an organism genetic material encoding one or more cistrons capable of expressing one or more immunogenic or therapeutic peptides and related methods.

Disclosed are polyolefin films suitable for packaging having Elmendorf values lower than 0.8N in both machine direction and cross direction are obtained from compositions comprising (percentages by weight): A) from 70% to 90% of a polyolefin matrix containing 30% of one or more crystalline propylene homopolymers and/or copolymers having a flexural modulus greater than or equal to 1800 MPa; B) from 10% to 30% of one or more mineral fillers.

A semiconductor device includes a rigid member embedded in a resin package body for supporting thereon outer leads that extend from the resin package body and test pads provided on the outer leads for testing the semiconductor device.

Clothes suitable for sporting wear are manufactured as those clothing an upper part of a body such as a sweatshirt and an undershirt or those clothing a lower part of a body such as a pair of shorts and a pair of training pants. The sleeves of upper part of body clothes have different lengths. The trouser legs of lower part of body clothes have different lengths. This realizes clothes which allow most effective limbs to move more effectively without the wearer having to roll-up a sleeve or a tro...

An inert electrode composition suitable for use in the production of metal by the electrolytic reduction of a metal compound dissolved in a molten salt is disclosed. The composition is formulated from a body containing metals and metal compounds designed to undergo displacement reaction upon sintering to form an interwoven network. The body also contains at least one non-reactive material, e.g., metal compound or metal. The interwoven network contains at least a metal compound and a second mater...

A process is disclosed for the preparation of highly pigmented fibrets, the product produced thereby and paper products containing the highly pigmented fibret. The fibret has a surface area of from 15 to 30 square meters per gram and comprises a polymeric host having an index of refraction of not more than 1.5 containing from 40 to 75 percent by weight of an inorganic light scattering pigment having an index of refraction of from 1.5 to 3.0. The fibrets are found to impart paper opacification to...

The present invention has two photometric circuits, namely photointegrating circuits, one of them is for day light photography and other is for flash photography. Normally the photointegrating circuit for flash photography is retained inoperatable, but when a flash device is mounted on the camera of this invention, the photointegrating circuit for day light photography is made inoperatable and the photointegrating circuit for flash photography is made operatable.

A material suitable for thermosetting includes a collection of hollow particles adhesively mixed with a thermosetting resin in such proportions that the mixture exists in a granular form and may be converted by thermosetting into a fused solid mass having a density not greater than 0.5 grams per cubic centimeter. The particles may be glass microbubbles or phenolic microballoons and the resin may be a hardenable Friedel-Crafts resin. The material according to the invention is more suitable for pa...
