Problems in the identity of "Crioceras" barremense Kilian, 1895 (Ancyloceratida, Late Barremian), and their proposed resolution
2010
17 pages; The study of "Crioceras" barremense KILIAN was undertaken as a part of the revision of the Hemihoplitidae. This species was considered "classic" and has been used as the index of an Upper Barremian subzone; this usage raises a number of problems. The type specimen from Tyrol was a fragment described and illustrated by UHLIG as Crioceras sp. ind. aff. roemeri. This specimen could not be retrieved, and a topotype could not be collected. Our study revealed that there is both a biostratigraphic hiatus and important differences between conceptions of this species: (1) that ascribed UHLIG's type specimen (Upper Barremian, Tyrol), (2) KILIAN's concept of the specimen he found and named "…
Pseudoshasticrioceras bersaci nov. sp. (Ammonoidea, Gassendiceratinae), and new ammonite biohorizon for the Upper Barremian of southeastern France
2009
International audience; Research in the Feraudianus Subzone of the Sartousiana Zone of the Barremian stage led to the discovery of a new species of Pseudoshasticrioceras: P. bersaci nov. sp. Its study provides evidence concerning the developments of the latest Gassendiceratinae BERT et alii, 2006, and the relationship between the genus Pseudoshasticrioceras DELANOY, 1998, and Gassendiceras BERT et alii, 2006. In particular, this new species is derived from Pseudoshasticrioceras magnini (DELANOY, 1992) by a minor revision in the processes of ontogenesis (retardation of ornamentation - neoteny). However, the evolution towards Pseudoshasticrioceras autrani DELANOY, 1998, implies a "failure" in…
Aroma Volatility from Aqueous Sucrose Solutions at Low and Subzero Temperatures
2004
International audience; The gas-liquid partition coefficients of ethyl acetate and ethyl hexanoate have been measured in water and aqueous sucrose solutions from 25 to -10 degrees C by dynamic headspace. Experiments were carried out on sucrose solutions at temperatures where no ice formation was possible. Results showed that when sucrose concentration increased, aroma volatility increased except for ethyl hexanoate and in the highest sucrose concentration solution (57.5%). A quasi-linear temperature decrease on aroma volatility was observed in sucrose solutions from 25 to around 4 and 0 degrees C. Then, from 0 to -10 degrees C, aroma volatility did not decrease: ethyl acetate volatility rem…

Vidēji lielo upju padziļināšanas ietekme uz makrofītu audžu sastopamību un izplatību
2016
Šobrīd Latvijā notiek meliorācijas sistēmu atjaunošana un rekonstrukcija, piesaistot Eiropas Savienības projektu finansējumu. Pie meliorācijas sistēmām pieskaitāmas arī upes. Viens no meliorācijas veidiem ir upju padziļināšana. Svarīgi noskaidrot, kā ūdensaugi reaģē uz padziļināšanas darbiem un cik ilgi jūtamas padziļināšanas sekas. Lai noteiktu, vai padziļināšanai ir būtiska ietekme uz ūdensaugu sastopamību, apsekotas četras upes, kas meliorācijas darbu rezultātā ir padziļinātas. Pētījumā apsekota Abzes, Aviekstes, Lobes un Misas upes 2015. gada septembrī. Katrā upē izvēlēti posmi, pamatojoties uz informāciju par upju meliorācijas darbiem no VSIA "Zemkopības ministrijas nekustamie īpašumi"…

Šī promocijas darba mērķis ir izpētīt, kā uzņēmumiem būtu jānosaka darbības joma, jāizstrādā un sekmīgi jāīsteno piegādes ķēdes vadība, lai sasniegtu augstu konkurētspēju, kā arī, kādi kritiski faktori nosaka to, lai piegādes ķēdes vadība nodrošinātu konkurētspēju. Parametri PĶV ietekmes novērtēšanai tika noteikti, balstoties literatūras un esošo pētījumu, kā arī situācijas izpētes analīzē, kuras rezultāti apkopoti visaptverošā konceptuālā modelī, kas sasaista īpašības, kas raksturīgas orientācijai uz klientu, piegādes ķēdes vadības briedumam (stratēģisks skatījums uz piegādes ķēdes vadību un operatīvs skatījums uz piegādes ķēdes vadību), līderībai un piegādes ķēdes rezultativitātei (to rak…
The Implementation of the Model of Innovative Economy and Principles of Cooperation for Sustainable Development in Latvia
2011
The theme of the Master Paper: The Implementation of the Model of Innovative Economy and Principles of Cooperation for Sustainable Development in Latvia. The aim of the Master Paper is to study and analyze the development of principles of innovative economy and cooperation in Europe and Latvia, to perform the analyses of the socio-economic situation, to mark the future perspectives for economic development in Latvia. The main problems of cooperation were studied based on the available information and theory. The alternative way of Latvia for possible sustainable development was marked by studying the experience of developed countries in implementing the principles of innovative economy. The…
