Viscosimetric investigation of the interaction between sodium dodecylsulfate micelles and a polymer drug carrier
1993
Abstract The viscosities of aqueous sodium dodecyl sulfate solutions with and without α,β-poly( N -hydroxyethyl)- dl -aspartamide (PHEA), at 15, 25 and 35°C are reported. The viscosities of SDS and of PHEA aqueous solutions are discussed in terms of the parameter D [D = ( η η 0 − 1)/φ] describing the non-ideal behavior of SDS micelles and of PHEA macromolecules. The viscosities of SDS plus PHEA aqueous solutions, discussed in terms of the parameter F [ F = η rel ( PHEA ) + η rel ( SDS ) − η rel ( SDS + PHEA )] M , demonstrate the occurrence of interactions between SDS micelles and the PHEA macromolecule. Both D and F are scarcely influenced by temperature variation.

SULT1A1 gene deletion in BRCA2-associated male breast cancer: a link between genes and environmental exposures?
2013
SULT1A1, a member of sulfotransferase superfamily, is a drug and hormone metabolizing enzyme involved in the metabolism of a variety of potential mammary carcinogens of endogenous and exogenous origin. Interestingly, the metabolic activity of SULT1A1 can be affected by varia- tions in gene copy number. Male Breast Cancer (MBC) is a rare disease and less investigated disease compared to female BC (FBC). As in FBC, the concurrent effects of genetic risk factors, particularly BRCA2 mutations, increased exposure to estrogens and environmental carcinogens play a relevant role in MBC. By quantitative real-time PCR with TaqMan probes, we investigated the presence of SULT1A1 gene copy number variat…
A study of the atmospherically important reactions of dimethylsulfide (DMS) with I2 and ICl using infrared matrix isolation spectroscopy and electron…
2012
The reactions of dimethylsulfide (DMS) with molecular iodine (I(2)) and iodine monochloride (ICl) have been studied by infrared matrix isolation spectroscopy by co-condensation of the reagents in an inert gas matrix. Molecular adducts of DMS + I(2) and DMS + ICl have also been prepared using standard synthetic methods. The vapour above each of these adducts trapped in an inert gas matrix gave the same infrared spectrum as that recorded for the corresponding co-condensation reaction. In each case, the infrared spectrum has been interpreted in terms of a van der Waals adduct, DMS : I(2) and DMS : ICl, with the aid of infrared spectra computed for their minimum energy structures at the MP2 lev…
Talsu un Vilkmuižas ezeru nogulumu uzkrāšanās apstākļu izmaiņu raksturs holocēnā
2019
Mainoties klimatam holocēnā, mainās mainās arī nogulumu uzkrāšanās apstākļi, kas ietekmē nogulumu īpašības. Savukārt nogulumos uzkrājušās augu makroatliekas ļauj spriest par veģetācijas rakstura un ezera līmeņa izmaiņām to attīstības gaitā. Maģistra darba mērķis bija noskaidrot kā mainījies nogulumu uzkrāšanās raksturs Vilkmuižas un Talsu ezeru attīstības laikā holocēnā, analizējot šo ezeru nogulumus ar karsēšanas zudumu un augu makroatlieku sastāva noteikšanas metodi. Pētījumā konstatēts, ka abu ezeru holocēna laikā uzkrājušos nogulumu sastāvā ir liels karbonātu īpatsvars, kas pakāpeniski samazinās griezuma augšdaļā, kā arī tajos salīzinājumā ar citiem ezeriem ir ļoti maza ūdensaugu sugu a…
Structural diversity and enzyme activity of volcanic soils at different stages of development and response to experimental disturbance
2008
We investigated the phospholipid fatty acid (PLFA) diversity and enzyme activities in soils from the volcano, Mt. Etna (Sicily). The soils were at sites which have been developing for different periods of time and have formed in volcanic lava of differing ages that have been supplemented with volcanic ejecta from subsequent eruptions. However, the plant communities indicated a marked successional difference between the sites and we have used this as a proxy for developmental stage. We have compared the structural and functional properties of the microbial communities in soils from the two sites and tested experimentally the hypothesis that the more diverse community was more resistant and r…
Bērnības svētku svinēšana Talsu novadā
2021
Bakalaura darbā “Bērnības svētku svinēšana Talsu novadā” pētīta Bērnības svētku gatavošanās un pasākuma norise, iesaistītās personas, viņu atmiņas un šīs tradīcijas nozīme Padomju Savienībā. Mērķis ir noskaidrot, kā notika Bērnības svētku svinēšana, un kāda bija svētku nozīme padomju laikā. Kā teorētiskā bāze izvēlēta pamatotā teorija, simboliskais interakcionisms, rituāla un ideoloģijas idejas. Pētījumā izmantota dokumentu un laikrakstu kontentanalīze, intervijas ar iesaistītajām personām palīdz uzzināt dalībnieku attieksmes un Bērnības svētku norisi. Noskaidrots, ka Bērnības svētki bija ikgadējs pasākums bērniem Padomju Savienībā, kas vienoja sabiedrību, noliedzot tradicionālos reliģiskos…
