Sensory and physical quality characteristics of shoulder and leg ham, kassler chops, back and belly bacon derived from South African indigenous Kolbroek (KB), African (AFR) and commercial Landrace X Large White (LR X LW) pig breeds were compared. The chemical quality characteristics were only determined on the ham, kassler chops and bacon derived from the two South African indigenous pig breeds...

A hue descriptor based on Logvinenko’s illuminantinvariant object colour atlas [1] is tested in terms of how well it maps hues to the hue names found in Moroney’s Colour Thesaurus [2] [3] and how well it maps hues of Munsell papers to their corresponding Munsell hue designator. Called the KSM hue descriptor, it correlates hue with the central wavelength of a Gaussian-shaped reflectance function...

This study evaluated the use of visible and near-infrared (VISNIR) spectroscopy to predict lean color stability in pork loin chops. Spectra were collected immediately after and approximately 1 h after rib removal on 1,208 loins. Loins were aged for 14 d before a 2.54-cm chop was placed in simulated retail display. Spectra were collected on aged loins immediately after removal from the vacuum pa...

Alfisols in USA taxonomy are “deciduous forest” soils having an argillic horizon with a base saturation the control section greater than 35%. geographically extensive and support productive agriculture deciduous forest ecosystems. Understanding Alfisol genesis, including presence intensity of dominant soil processes, facilitates best management practices that provide stewardship for these resou...

The problem of gamut mapping is of interest in achieving an optimum color reproduction whenever a translation from one device (source) to another device (destination) is requested and the source gamut differs from destination gamut. For printing applications, if the ICC profile specifications are used, gamut mapping is applied to build the color tables that characterize the printing device. Wit...

PURPOSE This study aimed to quantify the shift of colorimetric values in the Ishihara pseudoisochromatic test with aging of the plates. METHODS Three sets of Ishihara pseudoisochromatic plates with different published dates (printed in 1971, 1983 and 2001) were tested. Positions matching 32 dots with 13 colors were chosen from each set and the colorimetric values with the CIELAB and HSB/HLS c...

global warming is claimed to be the cause of climate change, which is often held responsible for water shortage.  let geopedology represents the complex process of soil formation, out of which much can be learnt about paleoecology; soil formation being a dynamic interaction between the atmosphere, biosphere, lithosphere, and the hydrosphere. in a multidisciplinary sustainability-oriented study ...

Three experiments evaluated whether the apparent reflexivity effect reported by Sweeney and Urcuioli (2010) for pigeons might, in fact, be transitivity. In Experiment 1, pigeons learned symmetrically reinforced hue-form (A-B) and form-hue (B-A) successive matching. Those also trained on form-form (B-B) matching responded more to hue comparisons that matched their preceding samples on subsequent...

Using 24 observers with normal color vision, perceived shifts in hue were determined for a yellow-red, green, and blue-green at intermittencies of 5, 10, and 20 cps. The hue shift for yellow-red was consistent with the hue shift exhibited by a deuteranomalous observer while the hue shift for green and blue-green was consistent with that exhibited by a protanomalous observer.
