Abstract: The present invention relates to a viability-retaining method of selecting corn embryos having a desired trait, said method comprising extracting embryos, removing associated non-embryogenic tissue or DNA from the exterior of the embryo; and extracting DNA directly from the embryo. The invention surprisingly shows that germinating embryos sampled directly for their DNA content are capable of continuing the germination process to form normal seedlings.

Abstract: This invention relates to systems and process for isolating DNA from biological materials such as seeds while retaining a viable seed for further use. The seed from which the DNA is isolated remains viable and is used or discarded based on the DNA analysis of the seed soak solution. The seed soak solution can have substantially all of the confounding maternal DNA from the seed eliminated from the seed soak solutions by employing intact seed pretreatments. This method is particularly useful for maize seed.

Abstract: The invention relates to a method for operating a glow plug with running engine, with the engine having a crankshaft and at least one cylinder. An effective voltage is generated from a vehicle electrical system voltage, with the effective voltage being applied to the glow plug. A plurality of measurement values of the combustion chamber pressure prevalent in the cylinder is measured during each working cycle of the cylinder, with the angular position of the crankshaft being determined for each individual measurement value. A characteristic value of the combustion process is determined from the evolution of the combustion chamber pressure measured in relation to the angular position of the crankshaft, and the determined characteristic value is compared with a setpoint value, and the effective voltage is set to a minimum value required for reaching the setpoint value.

Abstract: Process for operating a flame starting unit for an internal combustion engine, especially a diesel engine with flame glow plug (1), which is located in an air intake channel of the internal combustion engine and which is supplied with fuel via a fuel line (5). The fuel supply of flame glow plug (1) is metered depending on the respective operating phase of the internal combustion engine by there being valve (2) for controlling the amount of fuel in fuel line (5) for supplying flame glow plug (1), this valve being made especially as a clocked solenoid valve which is controlled via clock signals that have a frequency and/or length which are varied depending on which of a plurality of operating phases of the internal combustion engine is occurring.

Abstract: A rod-type flame glow plug, with a glow tube (5), an inner pole (7), a coil combination having at least one control and glow coil (4) located in series with an ignition coil (3.2) in the glow tube (5), the ignition coil (3.2) being located at the tip of glow tube (5), making in contact with the glow tube, avoids problems associated with nonuniform centering of the coils in the glow tube by the coil combination being located predominantly within a tubular component (1) made of a heat-resistant material. The inner surface of the tubular component (1) adjoins the coil combination, and the outer surface of the tubular component (1) adjoining the inner surface of glow plug (5).
