B and T lymphocytes are affected in lysosomal disorders--an immunoelectron microscopic study.
1991
Circulating lymphocytes of four patients with mucopolysaccharidoses II and IIIA, four patients with juvenile neuronal ceroid-lipofuscinosis, one patient each with glycogenosis type II, infantile neuronal ceroid-lipofuscinosis, and Gaucher disease were classified by immunoelectron microscopy as B or T lymphocytes. Disease-specific lysosomal inclusions as well as non-specific lysosomal organelles, especially Gall bodies were identified in B and T lymphocytes. These non-quantitative studies indicate that both B and T lymphocytes participate in the lysosomal storage process.
LE SOVRASTRUTTURE STRADALI IN CONGLOMERATO BITUMINOSO. RECENTI INNOVAZIONI PER LA TUTELA AMBIENTALE.
2008
L’attuale patrimonio stradale Italiano è costituito da 6.500 Km di Autostrade, 46.500 Km di strade Statali, 115.222 Km di strade provinciali e da 312.149 Km di strade comunali extraurbane, per un totale di 480.804 Km; a tale valore, va sommato lo sviluppo della viabilità urbana, non facilmente determinabile. Nel corso degli ultimi trenta anni, si è assistito all’incremento del traffico di veicoli pesanti che, unitamente alla diffusa tendenza di viaggiare in sovraccarico, determina il rapido deterioramento delle pavimentazioni stradali, soprattutto per accumulo di deformazioni permanenti; le conseguenti attività manutentive, ordinarie e straordinarie, necessarie per ripristinarne la funziona…
Sviluppo di un mezzo di prova in laboratorio per la valutazione della resistenza meccanica degli strati superficiali
2009
Gli Autori presentano i risultati di uno studiomirato alla messa a punto di un nuovo metodo di prova per la valutazione in laboratorio della resistenza agli sforzi tangenziali dei conglomerati bituminosi destinati a costituire strati d’usura. Alla base di un tale sviluppo prototipale, vi è la considerazione dellameccanica del contatto pneumatico-pavimentazione, al fine di riprodurre nel modo più realistico possibile l’effetto della sollecitazione tangenziale generata in corrispondenza di punti singolari, dato che proprio per questi punti è più difficile riprodurre in laboratorio la degradazione superficiale cui sono soggetti.
Aggregati artificiali dal riciclaggio di imballaggi PET
2016
In questo contributo si espongono le caratteristiche fisiche, le prestazioni meccaniche e il processo produttivo di aggregati leggeri di polietilentereftalto denominati alPET, ricavati principalmente dal riciclaggio di imballaggi per bevande. Attraverso l'analisi delle loro proprietà, si evidenzia la possibilità d'impiegare questi aggregati per la produzione di conglomerati bituminosi e cementizi destinati a componenti strutturali portanti dei viadotti stradali.
Apuvälineet ja teknologia osana fysioterapian ja fysioterapeutin ydinosaamista
2017
Aiempi tutkimustieto osoittaa, että fysioterapiaa ja apuvälineitä, terveys- ja hyvinvointiteknologiaa tai etäteknologiaa yhdistävää tutkimustietoa on vähän. Tarvitaan lisää tietoa apuvälineiden, teknologian ja etäteknologian käytöstä fysioterapiassa, niiden yhteydestä fysioterapian ydinosaamiseen sekä siitä, mitkä tekijät vaikuttavat niiden käyttöön fysioterapiassa. Tämän pro gradu -tutkielman tarkoituksena oli selvittää, miten suomalaisten fysioterapeuttien yksilölliset ja työhön liittyvät taustatekijät vaikuttavat apuvälineiden, terveys- ja hyvinvointiteknologian sekä etäteknologian käyttöön fysioterapian ydinosaamisalueilla. Lisäksi työn tarkoituksena oli selvittää, miten suomalaiset fys…
Search for Cosmic Neutrino Point Sources with Four Year Data of the ANTARES Telescope
2012
In this paper, a time-integrated search for point sources of cosmic neutrinos is presented using the data collected from 2007 to 2010 by the ANTARES neutrino telescope. No statistically significant signal has been found and upper limits on the neutrino flux have been obtained. Assuming an E ¿2 n; spectrum, these flux limits are at 1-10 ¿10¿8 GeV cm¿2 s¿1 for declinations ranging from ¿90° to 40°. Limits for specific models of RX J1713.7¿3946 and Vela X, which include information on the source morphology and spectrum, are also given.
Probing the origin of ultra-high-energy cosmic rays with neutrinos in the EeV energy range using the Pierre Auger Observatory
2019
Neutrinos with energies above 1017 eV are detectable with the Surface Detector Array of the Pierre Auger Observatory. The identification is efficiently performed for neutrinos of all flavors interacting in the atmosphere at large zenith angles, as well as for Earth-skimming τ neutrinos with nearly tangential trajectories relative to the Earth. No neutrino candidates were found in ∼ 14.7 years of data taken up to 31 August 2018. This leads to restrictive upper bounds on their flux. The 90% C.L. single-flavor limit to the diffuse flux of ultra-high-energy neutrinos with an Eν -2 spectrum in the energy range 1.0 × 1017 eV -2.5 × 1019 eV is E2 dNν/dEν < 4.4 × 10-9 GeV cm-2 s-1 sr-1, placing str…
Limits on point-like sources of ultra-high-energy neutrinos with the Pierre Auger Observatory
2019
With the Surface Detector array (SD) of the Pierre Auger Observatory we can detect neutrinos with energy between 1017 eV and 1020 eV from point-like sources across the sky, from close to the Southern Celestial Pole up to 60 in declination, with peak sensitivities at declinations around ∼-53 and ∼+55, and an unmatched sensitivity for arrival directions in the Northern hemisphere. A search has been performed for highly-inclined air showers induced by neutrinos of all flavours with no candidate events found in data taken between 1 Jan 2004 and 31 Aug 2018. Upper limits on the neutrino flux from point-like steady sources have been derived as a function of source declination. An unrivaled sensit…
Search for heavy neutrinos with the T2K near detector ND280
2019
This paper reports on the search for heavy neutrinos with masses in the range 140<MN<493 MeV/c2 using the off-axis near detector ND280 of the T2K experiment. These particles can be produced from kaon decays in the standard neutrino beam and then subsequently decay in ND280. The decay modes under consideration are N→ℓ±απ∓ and N→ℓ+αℓ−β(−)ν(α,β=e,μ). A search for such events has been made using the Time Projection Chambers of ND280, where the background has been reduced to less than two events in the current dataset in all channels. No excess has been observed in the signal region. A combined Bayesian statistical approach has been applied to extract upper limits on the mixing elements of heav…
CARCINOSARCOMA ARISING IN A DERMOID CYST OF OVARY: A CASE REPORT
2005
BACKGROUND: Transformation of a cystic benign teratoma of the ovary into a "carcinosarcoma" has very rarely been reported and its histogenetic origin is still debated. CASE PRESENTATION: A case of carcinosarcoma arising from a dermoid cyst is reported. The tumor showed cystic areas delimited by normal squamous epithelium, with transitional areas through dysplastic epithelium to "in situ" and infiltrating squamous cell carcinoma (SCC). The sarcomatous component showed compact tissue composed of round cells concentrically arranged around small vessels, spindle, and pleomorphic cells with a high nuclear-cytoplasmic ratio. Positive staining for vimentin, alpha smooth muscle actin and CD10, as w…
