Differences in the Density of Fungiform Papillae and Composition of Saliva in Patients With Taste Disorders Compared to Healthy Controls
2017
International audience; This study investigated the relation of the fungiform taste papillae density and saliva composition with the taste perception of patients suffering from diagnosed taste disorders. For this purpose, 81 patients and 40 healthy subjects were included. Taste was measured by means of regional and whole mouth chemosensory tests, and electrogustometry. Olfaction was assessed using the Sniffin Sticks. Fungiform papillae were quantified using the "Denver Papillae Protocol for Objective Analysis of Fungiform Papillae". In addition, salivary parameters [flow rate, total proteins, catalase, total anti-oxidative capacity (TAC), carbonic anhydrase VI (caVI), and pH] were determine…

Support for Conference Proceedings by ERAF Project "Support for the international cooperation projects and other international cooperation activities in research and technology at the University of Latvia" No. 2010/0202/2DP/2.1.1.2.0/10/APIA/VIAA/013
I TRE GIOIELLI DELLA PEDAGOGIA BUDDHISTA. BUDDHA, DHARMA E SANGHA
2020
This paper presents Buddhism as a paideia where the personal education takes place through the so-called three jewels: the Buddha, the Dharma and the Sangha, or the Master, the Way of Truth and the Spiritual Community. These are three refuges where the disciple carries out an interior search that, contrary to belief, does not happen in solitude but with the careful guidance of a Master and with the spiritual companions of the community. Finally, it’s affermed the great relevance of a millenary religion that today offers practices of interiority education to cultivate spiritual qualities such as wisdom, generosity, patience, love and compassion to build a new humanity.
Employment Protection Reform and Unemployment Inequality in a Matching Model (Reforme De La Protection De L'Emploi Et Inegalites Face Au Chomage Dans…
2007
This paper studies the impact of an unemployment protection legislation reform - a substitution between an experience rated tax and firing costs - on the level and structure of unemployment by skills. In this purpose, we consider a matching model which incorporates endogenous reservation products for job creation and job destruction, labor demand derives from a free entry condition and the tax rate aimed at financing unemployment benefits results from a balanced budget constraint. In this setting, it is shown that the introduction of the experience rated tax may improve the performance of the labor marekt; the drawbacks of such a reform depend on the degree of substitution between tradition…
Filling carbon nanotubes with magnetic particles
2013
Magnetic carbon nanotube composites were obtained by filling carbon nanotubes with paramagnetic iron oxide particles. Measurements indicate that these functionalized nanotubes are superparamagnetic at room temperature. Details about the production and characterization of these materials are described along with the experimental procedures employed. These magnetic carbon nanotubes have the potential to be used in a wide range of applications, in particular, the production of nanofluids, which can be controlled by appropriate magnetic fields.
Electrical conductance of carbon nanotubes with misaligned ends
2013
During a manufacturing process, when a straight carbon nanotube is placed on a substrate, e.g., production of transistors, its two ends are often misaligned. In this study, we investigate the effects of multiwall carbon nanotubes’ (MWCNTs) outer diameter and chirality on the change in conductance due to misalignment of the two ends. The length of the studied MWCNTs was 120 nm, while the diameters ranged between 4 and 7 nm. A mixed finite element-tight-binding approach was carefully designed to realize reduction in computational time by orders of magnitude in calculating the deformation-induced changes in the electrical transport properties of the nanotubes. Numerical results suggest that ar…
Carbon nanotubes under electron irradiation: Stability of the tubes and their action as pipes for atom transport
2005
The production and migration of carbon interstitials in carbon nanotubes under electron irradiation is studied experimentally and theoretically. It is shown that the threshold for displacing carbon atoms and the defect production rate strongly depend on the diameter of the nanotubes. Multiwalled nanotubes shrink by a loss of atoms and by diffusion of interstitials through the inner hollow in the axial direction. Thus, experimental evidence is given that nanotubes can act as nanoscale pipes for the transport of atoms.
Graphene, Fullerenes, Carbon Nanotubes: Electronic Subsystem
2017
This chapter introduces the reader to the analysis of the structural and electronic system properties of various carbon allotropes (CNT, graphene) and several molecular derivatives. The genesis of the electronic system formation is investigated in detail. Non-regular defected nanocarbon systems are considered for possible applications in different fields, including energy storage; chemical, biochemical and electrochemical sensing; water purification; and catalysis.
Assessing Radiation Hardness of SIC MOS Structures
2018
It is widely known that devices based on wide gap semiconductors show potential benefits in terms of saving mass, increasing power densities compared with standard Silicon ones [1]. The higher operating temperatures these components can withstand can also reduce the power budget currently used for cooling down power electronics. These factors are critical in space applications where, for example SiC devices are very promising. However, in this field reliability is a paramount requirement, and radiation conditions can compromise the usage of these new technologies.
Power allocation in multi-channel cognitive radio networks with channel assembling
2011
Accepted version of a paper in the book: 2011 IEEE 12th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC). Published version available from the IEEE:http://dx.doi.org/10.1109/SPAWC.2011.5990485 Consider power allocation for Secondary User (SU) packet transmissions over multiple channels with variable Primary User (PU) arrival rates in cognitive radio networks. Two problems are studied in this paper: The first one is to minimize the collision probability with PUs and the second one is to maximize the data rate while keeping the collision probability bounded. It is shown that the optimal solution for the first problem is to allocate all power onto the bes…
