Abstract: Pregnancy-associated glycoproteins (PAGs) are structurally related to the pepsins, thought to be restricted to the hoofed (ungulate) mammals and characterized by being expressed specifically in the outer epithelial cell layer (chorion/trophectoderm) of the placenta. By cloning expressed genes from ovine and bovine placental cDNA libraries, the inventors estimate that cattle, sheep, and most probably all ruminant Artiodactyla, possess possibly 100 or more PAG genes, many of which are placentally expressed. The PAGs are highly diverse in sequence, with regions of hypervariability confined largely to surface-exposed loops. Selected PAG that are products of the iOnvasive binucleate cells, expressed highly in early pregnancy at the time of trophoblast invasion and expressed weakly, if at all, in late gestation are useful in the early diagnosis of pregnancy. In a preferred embodiment, the invention relates to immunoassays for detecting these PAGs.

Abstract: A method of crystallizing amorphous silicon on a glass substrate relies on deliberately heating the glass substrate above its strain point during processing, making low temperature glasses, such as soda lime glasses, ideal for such use. Since the glass is plastic above this temperature while the silicon remains elastic, the glass is forced to conform to the shape defined by the silicon once this temperature is exceeded. This process relaxes any stresses which might otherwise be created in the glass or film, as long as the glass temperature is above the strain point. As the glass temperature is reduced back below the strain point, the glass becomes progressively more rigid and stresses will begin to build up in the film and glass. When cooled slowly, the stress in the film and the glass can be controlled by appropriate selection of a thermal expansion coefficient of the glass relative to that of silicon, particularly those with linear expansion coefficients in the range 4-10 ppm/° C.

Abstract: A thin film silicon solar cell is provided on a glass substrate, the glass having a textured surface, including larger scale surface features and smaller scale surface features. Over the surface is deposited a thin barrier layer which also serves as an anti-reflection coating. The barrier layer may be a silicon nitride layer for example and will be 70 nm±20% in order to best achieve its anti-reflection function. Over the barrier layer is formed an essentially conformal silicon film having a thickness which is less than the dimensions of the larger scale features of the glass surface and of a similar dimension to the smaller scale features of the glass surface.

Abstract: A method of making contacts on solar cells is disclosed. The front surface (41) of a substrate (11) is coated with a dielectric or surface masking layer or layers (12) that contains dopants of the opposite polarity to those used in the surface of the substrate material (11). The dielectric layers or layers (12) not only acts as a diffusion source for forming the emitter for the underlying substrate (11) when heat treated, but also acts as a metallization mask during the subsequent electroless plating with solutions such as nickel and copper. The mask may be formed by laser scribing (14) which melts the layer or layers (12), thereby more heavily doping and exposing zones (15) where metallization is required.

Abstract: Described herein is a method for reject analysis for use in any process where rejects occur. The method comprises using the application of multivariate statistical process control techniques, and allows the rejects from a process to be controlled in a simple and effective manner by deriving the T2 statistic for a series of variables or classification categories that impact reject performance characteristics. The calculated T2 value is compared with a standard value for the particular system. If the value exceeds the critical value , it suggests that there has been a significant change in the typical reject rate compared with the expected situation and therefore appropriate action can be taken to identify the cause of the change and procedures can be put in place to correct the problems, that is, to return the reject rate to the expected position.
