Characterization and Molecular Analysis of University of Arkansas Peach, Prunus persica (L.) Batsch, Flesh Types and Development of a Post-Harvest Evaluation Protocol for Arkansas Peach and Nectarine Genotypes
… pH, TA, skin and flesh characteristics, flavor, firmness, mealiness, juiciness, and browning were evaluated. Differences were found between the non-melting, slow-melting, and melting-flesh types and storage length for skin variables, firmness, and juiciness. Interactions among genotypes, …

Factors Affecting the Textural Properties of Pork
… differentiate products of varying quality. Pork firmness was correlated to a variety of traits (P < 0.05). Firmness had the strongest relationship to pH (r = 0.44; P < 0.05). Stepwise prediction equation included pH, L*, and marbling score, but only explained 33% of the variation in firmness. …

Identification of grapevine Pectate Lyase genes altering Berry Texture during ripening
… indicator of fruit freshness, for producers, the firmness is a critical trait influencing resistance to pathogen invasion and postharvest spoilage. Firm berries resist mechanical damage during transportation and storage, enhancing fruit quality and shelf life. Producers frequently apply plant …

Cognitive apprenticeship in architecture education: using a scaffolding tool to support conceptual design
… Vitruvian guiding principles of architecture: 'Firmness', 'Commodity' and 'Delight'. The study revealed that the intended use of the Cogs to cover aspects of Firmness and Commodity only resulted in the over-scaffolding of Firmness and the under-scaffolding of Delight. The students' resulting …

Effects of Light Availability and Canopy Position on Peach Fruit Quality
… the relationship between ground color and flesh firmness. Light levels were manipulated by use of shade cloth, reflective mulch, and aluminum foil. 'Norman' trees, with a randomly chosen half of the canopy covered with 73% shade cloth, had fruit with lower levels of red color, soluble solids …

Microwave appliance performance as affected by container geometry and material
… performance, as measured by evenness of cooking, firmness, and moisture content were compared. Three food items were heated in round, tube, loaf, and square containers made of clear glass, amber glass, thermoset polyester, and polysulfone. Unflavored gelatin, custard, and cakes were prepared three …
