La stima immobiliare su larga scala: l’analisi multilevel.
2007
La sistematica dei segmenti del mercato immobiliare comprende segmenti i cui immobili presentano una contiguità spaziale e possono identificarsi nell’isolato, nel quartiere, nell’area lottizzata, nella strada e segmenti i cui immobili sono dislocati nel territorio senza una continuità spaziale. Nel mercato immobiliare, la differenziazione della funzione di stima per segmenti, quartieri, ambiti di mercato o strade, è essenziale per l’interpretazione dei prezzi marginali delle caratteristiche. La stima del valore immobiliare è effettuata tenendo conto della struttura gerarchica dei dati. L’analisi multilevel permette di determinare rette di regressione diverse per i diversi ambiti di mercato.
Reduced CD27−IgD− B Cells in Blood and Raised CD27−IgD− B Cells in Gut-Associated Lymphoid Tissue in Inflammatory Bowel Disease
2019
The intestinal mucosa in inflammatory bowel disease (IBD) contains increased frequencies of lymphocytes and a disproportionate increase in plasma cells secreting immunoglobulin (Ig)G relative to other isotypes compared to healthy controls. Despite consistent evidence of B lineage cells in the mucosa in IBD, little is known of B cell recruitment to the gut in IBD. Here we analyzed B cells in blood of patients with Crohn's disease (CD) and ulcerative colitis (UC) with a range of disease activities. We analyzed the frequencies of known B cell subsets in blood and observed a consistent reduction in the proportion of CD27−IgD− B cells expressing all Ig isotypes in the blood in IBD (independent o…
Breakdown of the isobaric multiplet mass equation (IMME) at A=33, T=3/2
2000
Mass measurements on 3 3 , 3 4 , 4 2 , 4 3 Ar were performed using the Penning trap mass spectrometer ISOLTRAP and a newly constructed linear Paul trap. This arrangement allowed us, for the first time, to extend Penning trap mass measurements to nuclides with half-lives below one second ( 33 Ar : T 1 / 2 = 174 ms ). A mass accuracy of about 10 − 7 ( δ m ≈ 4 keV ) was achieved for all investigated nuclides. The isobaric multiplet mass equation was checked for the A = 33 , T = 3 / 2 quartet and found to be inconsistent with the generally accepted quadratic form. peerReviewed
Precision 71Ga – 71Ge mass-difference measurement
2016
The 71Ga(νe, e−) 71Ge reaction Q value has been measured with the JYFLTRAP mass spectrometer at the IGISOL facility of the University of Jyv¨askyl¨a to Q = 232.443(93) keV. This value agrees with previous measurements, though it features a much higher accuracy. The Q value is being discussed in the context of the solar neutrino capture rate in 71Ga. peerReviewed

A Review of Biosensors for Non-Invasive Diabetes Monitoring and Screening in Human Exhaled Breath
2019
Exhaled breath acetone has been identified as a diabetes biomarker for non-invasive diagnosis. Its detection using biosensors features has many advantages over the conventional means. This paper reviews the recent literature on the detection of exhaled breath acetone and acetone vapor of diabetic interest. The biosensors have been classified based on their transduction methods. The performance characteristics of the biosensors have been explored for comparison. The future trends are also highlighted.

Mass spectrometry coupled to chromatography systems and cultural heritage: a case study on the content of an ancient jar
2009
In this chapter an introduction to mass spectrometry will be given, with particular reference to mass spectrometry coupled to chromatography systems. Further some mass spectrometry applications in the field of cultural heritage will be briefly reported and discussed. Finally a experimental investigation on the content of an ancient jar will be reported. Together with experimental details a description of the techniques adopted, results obtained and forthcoming experiments will be also given.
