Volcanic gas emissions and degassing dynamics at Ubinas and Sabancaya volcanoes; implications for the volatile budget of the central volcanic zone
2017
Abstract Emission of volcanic gas is thought to be the dominant process by which volatiles transit from the deep earth to the atmosphere. Volcanic gas emissions, remain poorly constrained, and volcanoes of Peru are entirely absent from the current global dataset. In Peru, Sabancaya and Ubinas volcanoes are by far the largest sources of volcanic gas. Here, we report the first measurements of the compositions and fluxes of volcanic gases emitted from these volcanoes. The measurements were acquired in November 2015. We determined an average SO 2 flux of 15.3 ± 2.3 kg s − 1 (1325-ton day − 1 ) at Sabancaya and of 11.4 ± 3.9 kg s − 1 (988-ton day − 1 ) at Ubinas using scanning ultraviolet spectr…
Z-score and P-score for bankruptcy fraud detection: a case of the construction sector in Latvia
2019
To protect investment and ensure repayment of payables, recent studies have focused on identifying the relationships between company bankruptcy and internal fraud. The P-score model that is based on the most popular Altman Z-score model has been developed to indicate the manipulation of financial statements. Purpose of the study is to determinate the accuracy and the feasibility of P-score and Z-score models to detect fraudulent bankruptcy in regional conditions, based on reports of the Latvian construction companies that failed due to fraud, and during the verification of other known data. Research methodology is based on the background studies of P-score testifying, applying this approach…
Redox tuning and species distribution in Maya Blue-type materials: a reassessment.
2013
Maya Blue-type specimens prepared from indigo (1 wt %) plus kaolinite, montmorillonite, palygorskite, sepiolite, and silicalite are studied. Liquid chromatography with diode array detection, ultra-performance liquid chromatography coupled with mass spectrometry, and pyrolysis-silylation gas chromatography-mass spectrometry analyses of the extracts from these specimens combined with spectral and solid-state voltammetry, electrochemical impedance spectroscopy, and scanning electrochemical microscopy techniques provide evidence for the presence of a significant amount of dehydroindigo and isatin accompanying indigo and other minority organic compounds in all samples. Solid-state electrochemist…

Lisätty todellisuus matkapuhelinsovelluksissa
2010
Peura, Kimmo Tapio Lisätty todellisuus matkapuhelinsovelluksissa Jyväskylä: Jyväskylän yliopisto, 2010. 30s. Kandidaatintutkielma Tässä tutkielmassa käsitellään lisättyä todellisuutta ja sen sovelluksia matkapuhelimissa. Ensin esittelen, mitä lisätty todellisuus on ja miten se liittyy virtuaalitodellisuuteen. Tämän jälkeen kerron matkapuhelimesta lisätyn todellisuuden laitealustana. Lopuksi esittelen kolme matkapuhelinsovellusta, Layarin, Sekai Cameran ja Toozlan, joissa hyödynnetään lisättyä todellisuutta. Lisätty todellisuus toteutetaan yleensä käyttämällä läpinäkyviä näyttöjä tai monitoripohjaisia näyttöjä. Läpinäkyvät näytöt ovat usein päässä kannettavia näyttöjä ja niiden avulla voi t…
Chemical constituents of the volatile oil of Murraya koenigii leaves
2004
Abstract The chemical composition of the volatile oil of the fresh leaves of Murraya koenigii growing wild in Dehra Dun was analyzed by gas chromatography-mass spectrometry. Thirty-four compounds consisting of 97.4% of the oil were identified. The major constituents identified were α-pinene (51.7%), sabinene (10.5%), β-pinene (9.8%), β-caryophyllene (5.5%), limonene (5.4%), bornyl acetate (1.8%), terpinen-4-ol (1.3%), γ-terpinene (1.2%) and α-humulene (1.2%).

L’eros che non c’è. Meraviglie e contraddizioni dell’amore
2020
Nonostante sia fra le più logore e abusate, la parola ‘amore’ continua ad accendere il nostro entusiasmo, perché lascia intravedere una bellezza di cui non riusciamo a fare a meno e che, al tempo stesso, sembra sfuggirci continuamente. Cosa c’è dietro le promesse, spesso non mantenute, di questo formidabile sentimento? Perché l’amore resiste a ogni delusione, e siamo sempre tutti pronti a investire ancora sulle sue lusinghe? Si tratta di un intrattenimento ludico (Lucrezio), di una dipendenza patologica (Marco Aurelio), della più pericolosa delle illusioni umane (Schopenhauer) o della chiave segreta della vita (Platone)? Prendendo spunto dal vissuto quotidiano e spaziando dalla mitologia gr…
Hirayama disease: Nosological classification and neuroimaging clues for diagnosis
2022
Hirayama disease (HD) is a rare, benign, and nonprogressive motor neuron disease (MND) affecting the upper limbs. It usually presents with weakness and amyotrophy in a single upper extremity with an insidious onset between adolescence and the third decade of life. Since its description in 1959, HD has been known under several names and eponyms in Europe and in Asian countries probably due to its heterogeneous clinical features. Thus, the unclear nosological classification makes challenging the differential diagnosis between HD and other neuromuscular conditions, such as MNDs. However, apart from the nosological difficulties and the lack of evidence-based guideline for diagnosis, the neuroim…
Cardicola aurata sp. n. (Digenea: Sanguinicolidae) from Mediterranean Sparus aurata L. (Teleostei: Sparidae) and its unexpected phylogenetic relation…
2008
A new sanguinicolid trematode, Cardicola aurata sp. n., is described from gilthead seabream Sparus aurata L., from off the Spanish Mediterranean coast. The morphology of C. aurata sp. n. generally agrees with the diagnosis of the genus, however, in contrast to all other reported Cardicola spp. the male pore is located sub-medially at the posterior end of the body instead of sinistrally before the posterior end of the body. Based on a comparison of the morphology as well as partial 28S and ITS2 rDNA sequence data from the present species with that from closely related species, it was decided to emend the diagnosis of Cardicola rather than create a new genus, as the aberrant position of the m…
