Near-infrared emissive bacteriochlorin-diketopyrrolopyrrole triads: Synthesis and photophysical properties
2019
International audience; The synthesis of unprecedented energy transfer triads containing a near-infrared (NIR) emissive bacteriochlorin subunit and two diketopyrrolopyrrole (DPP) moieties linked to each other via ethynyl or zero-carbon spacers is presented. Their optical and fluorescence properties were determined in CHCl3 and toluene. These photophysical measurements highlight the ability of DPP scaffold to act as an effective energy donor, which once excited in the range 450-550 nm resulting nearly exclusively NIR emission of hydroporphyrin (ETE > 96%). Since DPP dyes are valuable structurally tunable fluorophores that may be used in the construction of high-performance multicomponent pho…
A magically nice guy: Parasocial relationships with Harry Potter across different cultures
2011
This study explored parasocial relationships (PSRs) with Harry Potter that readers from different cultures have developed. An overall sample of 2551 Potter fans from Germany (individualistic culture) and Mexico (collectivistic culture) completed an online questionnaire assessing their parasocial relationship with the character. Fans from the collectivistic culture rated Potter’s sociability higher than fans from the individualistic culture. For fans from both cultures, social attraction turned out as most important determinant of PSRs with Potter, while homophily ranked lowest. Overall, PSRs and fandom turned out to be quite similar across cultures, with some differences in character perce…
The microbiology of Lascaux Cave.
2010
Lascaux Cave (Montignac, France) contains paintings from the Upper Paleolithic period. Shortly after its discovery in 1940, the cave was seriously disturbed by major destructive interventions. In 1963, the cave was closed due to algal growth on the walls. In 2001, the ceiling, walls and sediments were colonized by the fungus Fusarium solani. Later, black stains, probably of fungal origin, appeared on the walls. Biocide treatments, including quaternary ammonium derivatives, were extensively applied for a few years, and have been in use again since January 2008. The microbial communities in Lascaux Cave were shown to be composed of human-pathogenic bacteria and entomopathogenic fungi, the for…

Darbā kalibrēta vienkārša, kvantitatīva metode entomopatogēno nematožu Steinernema feltiae (Filipiev, 1934) sastopamības novērtēšanai izmantojot Galleria mellonella (Linnaeus, 1758) kāpurus kā ēsmu. G. mellonella ēsmas tests tika kalibrēts divu dažāda vecuma sterilizētas kokosa šķiedras substrātā, kur tika konstatēta būtiska korelācija starp S. feltiae indivīdu blīvumu un G. mellonella mirstību 48h laikā gan svaigā (p<0.01, r=0.86, n=25), gan trīs gadus lietotajā (p<0.01, r=0.85, n=25) substrātā. Piecu nedēļu laikā dažāda vecuma rožu stādījumos ievāktos paraugos reģistrētas atšķirības pētījumā iesaistīto taksonu sastāvā, konstatēta S. feltiae telpiskās izplatības heterogenitāte, ilgstoša sa…
Relaciones de parentesco en las nuevas familias: disociación entre maternidad/paternidad biológica, genética y social
2015
Se describen y analizan las relaciones de parentesco en las familias monoparentales, homoparentales, tardías o de edad avanzada, con embarazos múltiples, reconstituidas, adoptivas y las que recurren a las técnicas de reproducción asistida. En estas familias se puede producir una disociación entre relaciones conyugales y relaciones filiales; entre sexualidad y reproducción; entre pareja conyugal, pareja parental y pareja progenitora; y la creación de lazos de filiación independientemente de tener una relación de pareja. Asimismo, frente a la biparentalidad y heteroparentalidad, se pueden establecer relaciones de monoparentalidad, homoparentalidad, coparentalidad y pluriparentalidad. Estas fa…
"She's straight, you delusional cunt!" : a study on bullying and homophobia in online fandoms
2016
Tämä kandidaatintutkielma käsittelee seksuaalisten vähemmistöjen syrjintää ja nettikiusaamisen esiintymistä internet-faniyhteisöissä. Edelliset tutkimukset kertovat nettikiusaamisen olevan haitallista ja vaikuttavan uhrien mielenterveyteen – usein jopa enemmän kuin kasvotusten tapahtuva kiusaaminen. Tutkielmaa varten tehty nettikysely suunnattiin “femslash”-faniryhmille. Näiden ryhmien median kulutukseen kuuluvat esimerkiksi tv-ohjelmien naishahmojen väliset (romanttiset) suhteet ja näistä suhteista puhuminen sekä eri materiaalien (kuten kuvien, videoiden ja fanifiktion) luominen ryhmien henkilöiden kesken. Kyselyn perusteella oli tarkoitus saada selville, miten yleistä näiden ryhmien kokem…
Determination of promethazine hydrochloride with bromophenol blue by a turbidimetric method and flow injection analysis
1992
Abstract A flow injection analysis procedure for the turbidimetric determination of promethazine is proposed. The sample solution is injected directly into the carrier reagent stream, which is composed of 1.16 × 10 −3 M bromophenol blue at pH 1.20. The calibration graph is linear over the range 25–197 ppm of promethazine. The influence of some foreign substances was also investigated. The method is applied to promethazine determination in a pharmaceutical formulation.
3,6-Bis(2-arylethenyl)-1,2,4,5-tetrazine - Synthese, Fl�ssigkristallinit�t und Photochemie
1995
3,6-Bis(2-arylethenyl)-1,2,4,5-tetrazines - Synthesis, LC Properties and Photochemistry The (E,E)-3,6-Bis(2-arylethenyl)-1,2,4,5-tetrazines 8 were prepared in a synthetic sequence starting with aromatic aldehydes 1 and cinnamic acids 2, respectively (Scheme 1). The rod-like conjugated molecules represent calamitic mesogens as well as extended chromophores. Hence, we investigated the formation of liquid crystals, achieved by the introduction of long flexible side chains, and the photochemical behaviour that is characterized by the fragmentation of the central ring (Scheme 3).
Partial purification and initial characterization of phytochrome from the mossAtrichum undulatum P. Beauv. grown in the light.
1988
The extraction and partial purification of phytochrome from light-grownAtrichum undulatum P. Beauv., a chlorophyllous moss, is described. Polyethyleneimine and salt fractionation followed by hydroxyapatite and Affi-gel-blue chromatography were used to separate phytochrome from chlorophyll, and to purify the pigment. All steps were performed in the presence of Triton X-100 which improved the yield by a factor of about three. The protein has a molecular weight some-what larger than that ofAvena phytochrome (124 kDa), as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and immunoblot analysis. It cross-reacts with a monoclonal antibody against phytochrome from etiolated …
