Abstract: The wheat Rht gene and homologues from other species including rice and maize (the D8 gene), useful for modification of growth and/or development characteristics of plants. Transgenic plants and methods and means for their production.

Abstract: The GAI gene of Arabidopsis thaliana has been cloned, along with mutant and homologue gene sequences. Expression of such genes a plants affects characteristics in the plants including growth. GAI expression inhibits growth of plants, which inhibition is antagonized by gibberellin (GA). Expression of gai mutants confers a dwarf phenotype which is GA-insensitive. Manipulation of expression of GAI and gai genes in plants results in tall or dwarfed plants. Dwarf plants are useful in particular for reduction in crop losses resulting from lodging.

Abstract: This invention relates to the genetic control of growth and/or development of plants and the cloning and expression of genes involved therein. More particularly, the invention relates to the cloning and expression of the GAI gene of Arabidopsis thaliana, and use of the gene in plants.

Abstract: A small modular portable flooded bed scrubber suitable for installation in confined areas is disclosed. The scrubber may be formed in a plurality of modular units, such as two or three units, and requires of minimum of accessory devices. The scrubber effluent can be removed by gravity. The pressure drop across the scrubber is low and the air velocity is sufficiently low that fan stalling and ambient noise are greatly reduced. A collector structure collects water droplets and prevents bypass of air and droplets around the entrainment module and prevents leakage at the joinery of the modules.

Abstract: A scrubber filter used, for example, in connection with a flooded bed scrubber system, characterized as a series of nylon or plastic brushes arranged, in rows, within a frame and overlaid with mesh, where the filter is disposed, during use, in a tilted relationship, i.e. tilts forward in the direction of oncoming contaminated air. In an alternative approach, the filter may be oriented angularly in a lateral direction with respect to such contaminated air. In any event, the density of the brushes at the tilted/angled position serves for the effective capture of micron particles, where larger particles are lodged, and subsequently displaced, on and from the aforesaid mesh.

Abstract: A noise-suppressing air intake for a ventilation fan comprising a base having at least one sidewall and an open top and a cap positioned over the base with a portion of the cap being aligned with a portion of the base, and another portion of the cap overlapping a portion of the sidewall of the base to define a downwardly-facing, shielded air inlet therebetween. An air outlet is located in the aligned portions of the cap and base.
