Studies involving mutants of the gene SPATULA indicate that it promotes the growth of carpel margins and of pollen tract tissues derived from them. We show that it encodes a new member of the basic-helix-loop-helix family of transcription factors. SPATULA is expressed in marginal and pollen tract tissues throughout their development confirming its role in regulating their growth. It is also exp...

To help understand the process of carpel morphogenesis, the roles of three carpel development genes have been partitioned genetically. Mutants of CRABS CLAW cause the gynoecium to develop into a wider but shorter structure, and the two carpels are unfused at the apex. Mutants of a second gene, SPATULA, show reduced growth of the style, stigma, and septum, and the transmitting tract is absent. D...

Angled polyurethane fiber arrays are modified by adding soft spherical and spatula shaped tips via dipping. These fibers are characterized for adhesion and friction and compared with unmodified fibers and flat material samples. Sphere and spatula tip fiber samples demonstrate increased adhesion, with 10 and 23 times the maximum adhesion of the unmodified fiber sample, respectively. The sphere a...

THE instrument shown in Fig. 1 (a) and (b) is a spatula in two sizes, one smaller for children and the other larger for adults, curved to conform with the forward convexity of the tarsal plate in the upper eyelid; the upper edge of the spatula is rounded and curved to be accommodated in the superior fornix. That part of the spatula which projects below the upper lid margin, after its insertion ...

BACKGROUND the absence or delay of the swallowing reflex is considered a significant sign of dysphagia. Therefore, the therapy traditionally applied to these cases consists in increasing the intra-oral input through cold touches (0 or 00 larynx mirror) on the inferior portion of the inferior third of the palatoglossus arch. AIM to identify in healthy young individuals which oropharyngeal regi...

This study evaluates how different culinary spatula (turning shovel) designs affect cooking performance during stir-frying. A straight-handled spatula (0°) and three bent-handled spatulas (15°, 30° and 45°) were evaluated across two handle length levels (25 cm and 30 cm). The criterion measures included food-frying efficiency, work posture and subjective rating of perceived discomfort. In a lab...
