Combustion behavior of kraft black liquor droplets from hot water pretreated hardwood and softwood chips

2016

This paper describes the combustion behavior of birch and spruce kraft black liquors obtained from an integrated forest biorefinery concept in which a hot water extraction of chips was performed before pulping. This pretreatment, aiming mainly at the recovery of various hemicellulose-derived materials, increased the concentrations of lignin and hydroxy acids in black liquors, compared with those in the reference black liquors without any process modification. On the other hand, the pretreatment decreased the concentrations of volatile acids and other organics (extractives and hemicellulose residues). Because of these characteristic changes, the total burning times (pyrolysis time plus char …

Mustialan maanviljelysopiston rakennettu ympäristö vuosina 1838-1920

2011

Tutkielmani käsittelee Suomen ensimmäisen käytännöllis-tietopuolisen maanviljelysoppilaitoksen rakennettua ympäristöä. Mustialan maanviljelysopisto perustettiin 1830-luvulla Suomen Talousseuran toimesta Tammelaan Kanta-Hämeeseen. Ensimmäiset oppilaat aloittivat opistossa opiskelun vuonna 1840. Vielä nykyäänkin Mustialassa voi opiskella maaseutuelinkeinojen koulutusohjelmassa. Nykyisin yli 50 rakennusta käsittävästä kokonaisuudesta rajaan tutkielmani käsittämään tiiviin rakennusryhmän, joka käsittää opisto- ja maatilapihan sekä navettapihan rakennukset. Näiden pihaneliöiden rakentumista seuraan vuosien 1838–1920 välisenä aikana. Tarkastelen Mustialan maanviljelysopistoa asettamalla sen kultt…

Qualità della didattica universitaria e sviluppo della capacità decisionale. Il modello ADVP per garantire i passaggi da L-19 a LM-85bis.

2020

Il presente contributo intende offrire una riflessione sulle competenze attese individuate attraverso la formulazione dei descrittori di Dublino dei CdS in Scienze dell’Educazione (L-19) e Scienze della Formazione Primaria (LM-85bis) istituiti presso l’Ateneo di Palermo e nello stesso tempo proporre un modello per lo sviluppo della maturità professional e necessaria a garantire scelte consapevoli, mature e responsabili. L’analisi condotta ci ha permesso, in una seconda fase di individuare gli obiettivi formativi finali scelti seguendo il modello proposto dalle Linee Guida dell ’Anvur, e di scegliere il modello dell’Activaction du Developpement Vocationnel et Personnel quale strumento per lo…

How relevant are local climate zones and urban climate zones for urban climate research? Dijon (France) as a case study.

2018

17 pages; International audience; Several typologies of urban surface properties have been proposed, in recent years, for urban heat island studies and climate modeling. Some were specifically developed for cities and urban climate issues, like the Urban Climate Zones, and the more recent Local Climate Zones. The initial objective of this paper is to evaluate the capacity of these two typologies to identify thermal environments in and around cities, and to determine which typology best captures the daily spatio-temporal patterns of surface and urban canopy heat islands. To simulate urban climate with a model, LULC data based on a given typology are required. To avoid circularity, we combine…

Infrequent promoter methylation of the MGMT gene in liver metastases from uveal melanoma.

2008

Uveal melanoma is associated with a high mortality rate once metastases occur, with over >90% of metastatic patients dying within less than 1 year from metastases to the liver. The intraarterial hepatic (iah) administration of the alkylating agent fotemustine holds some promise with response rates of 36% and median survival of 15 months. Here, we investigated whether the DNA-repair-protein MGMT may be involved in the variability of response to fotemustine and temozolomide in uveal melanoma. Epigenetic inactivation of MGMT has been demonstrated to be a predictive marker for benefit from alkylating agent therapy in glioblastoma. We found a methylated MGMT promoter in 6% of liver metastases fr…

Combustion properties of spruce black liquor droplets : Sulfur-free pulping and influence of hot-water pretreatment

2016

Hot-water pretreatment of lignocellulosics prior to sulfur-free alkaline pulping is an interesting approach for recovering value-added carbohydrate- and lignin-derived materials. This paper investigated the chemical composition variations and combustion properties of the black liquors (BLs) from three different cooking processes: two sulfur-free soda-anthraquinone (soda-AQ) and oxygen-alkali (O2-NaOH) cooks and kraft cook, before and after hot-water pretreatment of the spruce sawdust. Relatively less aliphatic acids but more lignin were present in the BLs after hot-water pretreatment as cooking time prolonged. In general, the burning time decreased as follows: soda-AQ BL > O2-NaOH BL ≅ kraf…

Wine-making with protection of must against oxidation in a warm, semi-arid terroir

2016

In order to defend varietal aromas from oxidation before alcoholic fermentation, two musts were prepared from white grapes pre-cooled and added with ascorbic acid and solid CO2 (trial ACO2) or SO2 (trial BSO2). Experiments were performed with grapes of a white grape variety indigenous to western Sicily, the wines from which, obtained by vinification of musts protected from oxidation and poor in copper, as previously proven, have aroma descriptors ascribed to passion fruit and grapefruit skin. The smaller content in flavanols in the ACO2 trial, demonstrated that the use of solid CO2, instead of SO2, reduced the extraction of such polyphenols from grape solids. The higher content in hydroxyci…

Etude d'une microflore levurienne champenoise

1982

<p style="text-align: justify;">Pendant quatre années consécutives, on a suivi en Champagne, l'évolution de la microflore levurienne depuis la baie de raisin jusqu'au vin clair. Les résultats montrent une influence sensible sur la microflore, d'une part de certains traitements phytosanitaires et d'autre part des opérations liées à la vendange et au traitement des moûts. Grâce à un milieu de culture électif spécial, les auteurs ont amélioré la séparation des colonies de <em>S. cerevisiae</em> et de <em>S. bayanus</em>.</p><p style="text-align: justify;">+++</p><p style="text-align: justify;">For four consecutive years the evolution of yea…

Telpu tekstiliju tradīcija Ziemeļlatgalē 20.gs.20.- 80.gados

2017

Maģistra darbā „Telpu tekstiliju tradīcija Ziemeļlatgalē 20. gs.20. – 80. gados” aplūkota telpu tekstiliju darināšanas, rotāšanas un lietošanas tradīcija Latgales ziemeļos. Pamatojoties uz intervijām ar teicējiem, autores privātkolekcijā esošajiem rokdarbu tehniskajiem zīmējumiem jeb musturiem, telpu tekstiliju paraugiem no kultūrvēstures muzeja „Vēršukalns” un teicēju privātā krājuma un teorētisko literatūru, pētījumā atspoguļota tradīcijas pastāvība un attīstība. Darbā secināts, ka tradīcijas attīstībā liela loma ir tradīcijas nesēja personībai un vēsturiskajiem apstākļiem. Tradīcijas saglabāšanā 20. gs. nozīmīgi bijuši rokdarbu tehniskie zīmējumi, kas līdzīgi rokrakstu literatūrai izplat…
