Consumer acceptance of Italian or New Zealander lamb meat: an Italian case study
A Central location test was performed to compare heavy Apennine lamb meat to New Zealander lamb meat in order to create a Protected Geographical Indication for lamb meat. Roasted New-Zealander and heavy Apennine lamb legs were tested by 106 consumers according to the following experimental plan: blind phase (B) without any possibility to recognize the meat type tasted, expected phase (E) in which were described the characteristics of the two types of meat without tasting, informed phase (I) in which the tasted meat was recognized in provenience. Results showed in a nine point scale of appreciation for flavour, juiciness and overall pleasure, the highest values in Apennine lamb meat. B test showed the highest value for overall pleasure (P<0.01). Interaction, Italian lamb x Informed test showed the highest values for all the parameters except for overall liking for which Italian lamb x E test showed the highest values. About foreign lamb meat B test showed higher values than I and E test. Information about lamb meat origin showed disconfirmation for tenderness in Italian lamb meat. Foreign lamb meat showed a positive disconfirmation for flavour and overall pleasure, that confirm the better perception by consumers in blind consumption than in the informed one
Multi-time delay, multi-point Linear Stochastic Estimation of a cavity shear layer velocity from wall-pressure measurements
Multi-time-delay Linear Stochastic Estimation (MTD-LSE) technique is thoroughly described, focusing on its fundamental properties and potentialities. In the multi-time-delay ap- proach, the estimate of the temporal evolution of the velocity at a given location in the flow field is obtained from multiple past samples of the unconditional sources. The technique is applied to estimate the velocity in a cavity shear layer flow, based on wall-pressure measurements from multiple sensor
Geophysical methods to support correct water sampling locations for salt dilution gauging
To improve water management design, particularly
in irrigation areas, it is important to evaluate the baseline
state of the water resources, including canal discharge.
Salt dilution gauging is a traditional and well-documented
technique in this respect. The complete mixing of salt used
for dilution gauging is required; this condition is difficult to
test or verify and, if not fulfilled, is the largest source of uncertainty
in the discharge calculation. In this paper, a geophysical
technique (FERT, fast electrical resistivity tomography)
is proposed for imaging the distribution of the salt
plume used for dilution gauging at every point along a sampling
cross section. With this imaging, complete mixing can
be verified. If the mixing is not complete, the image created
by FERT can also provide a possible guidance for selecting
water-sampling locations in the sampling cross section. A
water multi-sampling system prototype aimed to potentially
take into account concentration variability is also proposed
and tested.
The results reported in the paper show that FERT provides
a three-dimensional image of the dissolved salt plume and
that this can potentially help in the selection of water sampling
points
