Abstract:

In one embodiment, a gas-sensing probe for use in a combustor includes an elongated support member, a housing, a gas sensor and sensor wires. The housing is attached to an end of the support member, and the gas sensor is rigidly supported within the housing. In another embodiment, a gas-sensing probe for use in a combustor includes an elongated support member, a housing, and a gas sensor. The housing is removably attached to an end of the support member, and the gas sensor is disposed within the housing so that the gas sensor and housing are removable from the distal end of the support member as a unit. In another embodiment, a gas-sensing probe comprises an elongated support member, a gas sensor, and a calibration tube. The elongated support member has a proximal end and a distal end, and supports the gas sensor at the distal end thereof. The calibration tube extends along a length of the support member, and has a first opening near the proximal end of the support member and a second opening, in fluid communication with the first opening, near the distal end of the support member and the gas sensor.

Abstract:

A method for regeneration of sunflower plants via shoot induction from cotyledon explants prepared from non-germinated sunflower embryos is described. Several methods for preparing explants by dissection of mature and immature fully-formed embryos are provided. Explants are prepared to insure that substantially all of the induced shoots derive from single cotyledon cells. Appropriately prepared explants are cultured on a shoot induction medium containing a combination of BA and NAA. Induced shoots are rooted and the resulting plantlets are grown into mature sunflower plants. This regeneration method is efficient, rapid and employs a convenient explant source, sunflower seed. This regeneration method is particularly useful in combination with methods for introduction of foreign DNA into sunflower cells and tissue.
