Part of this work was financially supported by the Italian Ministry of University and Research with the research Grant PRIN 20…
Influence of calcium on the effects of okadaic acid and its interaction with caffeine and theophylline in rat myometrium.
1994
The effects of okadaic acid (OA), a monocarboxylic acid produced by marine dinoflagellates belonging to the genera Dinophysis and Prorocentrum, and their interactions with theophylline and caffeine were studied on the rat-isolated uterus in a calcium-containing medium and a calcium-free medium in the presence of 10−3 M EGTA. Okadaic acid (5 × 10−6 to 5 × 10−5 M) induced a concentration-dependent contraction of the rat-isolated uterus corresponding, with 5 × 10−5M, to 142.3±6.1% (n = 7) of the contraction induced by oxytocin 10−6 M. The time to peak tension was inversely proportional to the maximum effect produced. The contraction was not sustained and was followed by a concentration-depende…

Tēžu krājumā apvienotas LU Latviešu valodas institūta rīkotās akadēmiķa Jāņa Endzelīna (1873–1961) 149. dzimšanas dienas atcerei veltītās starptautiskās zinātniskās konferences tēzes, kuras iesnieguši 36 konferences dalībnieki no Latvijas, Lietuvas un Polijas. Akadēmiķa atceres konferences tiek rīkotas jau kopš 1963. gada. 2022. gada 22.–23. februāra konference “Valodas reģionālie varianti” tika veltīta dialektoloģijai. Konferences tēžu krājums ietver pētījumus par dialektiem, izloksnēm un valodas paveidiem – valodu, ko runā pagastos, novados un plašākos reģionos. The collection of abstracts comprises 33 summaries of papers presented in the International Scientific Conference „Regional Vari…

Bio materials with reclaimed asphalt: from lab mixes properties to non-damaged full scale monitoring and mechanical simulation
2019
Three innovative environmentally friendly pavement materials, designed with 50% of Reclaimed Asphalt and three different biomaterials (2 bio-additivated bitumens and 1 bio-binder), were produced in an industrial plant. These mixes were tested in lab and also at full scale using an Accelerated Pavement Test facility. The asphalt mix viscoelastic properties were measured in lab and their intrinsic viscoelastic response were simulated. These rheological models are used to simulate the pavement mechanical response using both elastic and viscoelastic multilayer codes. Hence, full scale measurement performed during the full scale test at an early stage (without damages) can be compared with these…
