Taralli is a bakery snack food, typical of the south of Italy, that has currently become very popular worldwide as a savory snack or bread substitute. However, few studies have focused on its physical and sensory characteristics. The present work aims to select sensory and instrumental information that is able to characterize Taralli with similar formulation and size. For sensory characterization purposes, conventional profiling was applied on samples from different producers. All samples were also subjected to physical analysis of appearance and textural proprieties. Three samples of the set, differing only in storage time, were evaluated to assess changes in sensory characteristics during this period and a discrimination test (triangle test) was also applied for this purpose. The test results confirmed that the sensory analysis allowed a description of the entire range of characteristics resulting from stimulation of senses by physicochemical properties of the food. This methodology was effective in evaluating the quality characteristics and identify differences between Taralli samples during different storage times. Instrumental tests were also applied to assess food quality. The results revealed that a combined approach allowed obtaining more information about the product characteristics and definition of quality standards. This study also suggests the use of physical parameters obtained by simple and rapid instrumental tools can support sensory analysis, especially for evaluations that are fatiguing, when decisions made with the sensory data are critical or to provide objective reference standards that are suitable for training purposes.

In the future hadron facility FAIR, the HESR ring will supply antiprotons in the momentum range 1.5-15 GeV c as projectiles to study charm, strangeness and a wide range of other Physics topics. For all these reactions it will be necessary to use internal targets and in particular, for the production of systems with double strangeness, a solid 12C target will be used. Inserting a solid target inside an antiproton ring creates two main problems: a large background on the detectors due to the overwhelming amount of annihilations and a strong depletion of the beam due to all the hadronic and Coulomb interactions of the antiprotons with the 12C nuclei. The width of the target plays a crucial role in minimizing these unwanted effects. Two wire-shaped prototypes have been already realized, starting from a thin diamond disk. The wire shape has been obtained by using a femto-edge laser. One prototype has been submitted to irradiation by protons of 1.5 MeV and to simultaneous Back-Scattering control to test the impurity level, the 12C density, the radiation hardness and possible phase modifications during irradiation. Both the prototypes have been submitted to Micro-Raman spectroscopy in order to scan the carbon phases along the width. The results show performances which satisfy the experimental requirements.

Mobility coupling effects due to remote Coulomb scattering (RCS) are demonstrated for the first time in FD-SOI CMOS devices subjected to front and back interface electrical degradation. The evolution with stress time of the front and back threshold voltages as well as of the low field mobility values has been obtained. The front and back interface mobility degradations were then correlated to the stress induced interfacial charge variations for each stressed interface. This enabled the clear demonstration of the existence of mobility coupling effects between the front and back interface by RCS through the silicon film.

The main physico-chemical modifications during the cooking process of laboratory-made biscuits were monitored at different cooking times (0, 2, 4, 6, 8, 10, 12 min). Moisture content, surface colours and textures were measured. In addition the evolution of the flavour release was performed by means of an electronic nose equipped with 10 metal-oxide sensors. Multivariate statistical analyses were performed to distinguish samples as a function of their physico- chemical characteristics. The electronic nose permitted differentiation between raw, under cooked, wellcooked and over cooked products. Similar and complementary information was obtained considering both electronic nose data and traditional physico-chemical cooking indexes. The obtained results showed that it could be feasible to monitor the changes in the biscuit's aroma and cooking level directly during the process by using an electronic nose with a simplified gas sensor array, as well as allowing the optimization of the technological parameters. --Key words: biscuit, colour, cooking process, electronic nose, texture--

An innovative technique to access the nuclear matrix elements entering the expression of the life time of the double beta decay by relevant cross sections measurements of double charge exchange reactions is proposed. A key aspect of the project is the use of the MAGNEX large acceptance magnetic spectrometer, for the detection of the ejectiles, and of the LNS K800 Superconducting Cyclotron (CS), for the acceleration of the required high resolution and low emittance heavyion beams, already in operation at INFN Laboratory Nazionali del Sud in Catania (Italy).

A new 'ratio' method for effective channel length and threshold voltage extraction in MOS transistors is proposed. The method, which relies on the same function as that used in the well known shift and ratio procedure, enables the effective channel length and threshold voltage difference to be extracted from simple linear regression applied to a short versus long channel correlation plot of the function Y(V sub(g) = I sub(d) square root g sub(m) (I sub(d ) being the drain current and g sub(m) the transconductance). This method has successfully been applied to 0.184). 1 mu m CMOS technologies.

In order to fulfill the goal of producing higher rates of doubly strange hyperons, the P̄ANDA collaboration will use the antiproton ring HESR at the future facility FAIR. The low energy hyperon production by an antiproton beam requires to insert a solid target inside the ring. Unwanted side effects of such an insertion are the overwhelming amount of annihilations, which would make the detectors blind, and the fast depletion of the bunch, which circulates inside the ring. The choice of the target material impacts the hyperon production yield: Carbon turned out to provide enough initial hyperon deceleration and keep secondary interactions below a tolerable level. The use of a very thin Diamond target, together with beam steering techniques, seems to be a satisfactory solution to the above problems and will be described hereafter.
