The present invention discloses a resin composition containing 26-70 weight% of thermoplastic polyester resin, 10-30 weight% of polyester elastomer, and 20-44 weight% of vinylidene chloride resin and a biaxially stretched heat shrinkable film having cold resistance and oxygen gas barrier property comprising said resin composition, and further a biaxially stretched heat shrinkable laminated film ha...

It has now been found that relatively short peptides such as tripeptide glycyl-prolyl-glycine are able to effectively inhibit HIV infection of cells and syncytia formation between HIV infected and non-infected cells. The peptides are suitable for therapy of patients infected with HIV and in prevention of HIV infection.

A method of making a gas-permeable liquid-impermeable membrane includes the steps of perforating a film of linear low density polyethylene (or other suitable polyolefin) in such a way as to yield an array of holes each having an average diameter of approximately 350 , and then solution coating the needle d film with a porous polyurethane material having pores of a pore size of 1 to . Such a film...

The invention relates to a mobile two-section slope conveyor for transporting excavated material or the overburden in an opencast pit. The conveyor according to the invention consists of a conveyor (16) fastened on a bridge (12) and a second conveyor (15) fastened on the transfer machine. The bridge (12) is supported on the one hand on a crawler-mounted travel gear (13) and on the other hand on ...

2090119 9203581 PCTABS00011 A process for enhancing fluidization in a fluidized bed reactor chamber (18). In a preferred embodiment, molybdenum oxide (12) is reduced to molybdenum metal in the fluidized bed (30). An oxidant (52) is introduced into the fluidized bed (30) during the reducing process in order to substantially prevent or reverse the agglomeration of reduced particles (42).

In a laser beam delivery system for a surgical laser beam, steering and scanning of the laser beam along the target (20) in transverse (X and Y) directions is accomplished in a mechanically simple and fast-responding manner. Closely adjacent to the objective lens assembly (24) of the delivery system is a pair of prisms (12, 14), i:e. Risley prism Ar Herschel prism; positioned on the axis (16) of ...
