Fenoloģiskais fotomonitorings LU Botāniskajā dārzā
2016
Bakalaura darbā izvērtēta digitālo fotogrāfiju izmantošanas efektivitāte un iespējas fenoloģijas pētījumos, Latvijas Universitātes Botāniskā dārza piemērā. Veicot pētījumu, tika izmantoti digitālie fotoattēli no Latvijas Universitātes tīkla kameras datu bāzes, kas uzņemti no 2009. līdz 2014. gadam. Pēc datu atlases, apstrādes un analīzes, tika noteiktas pavasara un rudens fāzes trīs kokiem – parastajai ievai Padus avium, parastajai kļavai Acer platanoides un āra bērzam Betula pendula, kā arī noteiktas ziemas mēnešiem raksturīgās fāzes. Katrai no fāzēm ir noteikts iestāšanās datums, ilgums, raksturota tā attīstība, veikts salīdzinājums starp gadiem. Papildus datu bāzē pieejamajiem materiālie…

Brak sprzeczności planu miejscowego ze studium jako jedna z zasad sporządzania planu miejscowego
2022
Zagadnienie relacji między miejscowym planem zagospodarowania przestrzennego a studium uwarunkowań i kierunków zagospodarowania przestrzennego gminy stanowi przedmiot wieloletnich badań przedstawicieli nauki prawa, a także obszernych wypowiedzi sformułowanych w orzecznictwie. Wymóg, by plan miejscowy nie naruszał ustaleń studium, jest wymogiem ustawowym zawartym w przepisach art. 20 ust. 1 w zw. z art. 9 ust. 4 i art. 15 ust. 1 ustawy o planowaniu i zagospodarowaniu przestrzennym. Okoliczność, że w dalszym ciągu dochodzi do unieważnienia uchwał planistycznych w całości lub w części z powodu sprzeczności ze studium, wskazuje na aktualność tej problematyki oraz potrzebę dalszego popularyzowan…

A 2600-year record of past polycyclic aromatic hydrocarbons (PAHs) deposition at Holzmaar (Eifel, Germany)
2014
Polycyclic aromatic hydrocarbons (PAHs) are a proxy for climate- and human-related historical fire activity which has rarely been used beyond 1800 AD. We explored the concentration and composition patterns of PAHs together with other proxies (charcoal, C, N, S, δ13C, δ15N, and δ34S) in a sediment core of Holzmaar as indicators of variations in climate and anthropogenic activity over the past 2600 years. The concentrations of pyrogenic PAHs remained low (< 500 ng g− 1) from the pre-Roman Iron Age (600 BC) until the first significant increases to ca. 1000–1800 ng g− 1 between 1700 and 1750 AD related to regional iron production. The highest increases in pyrogenic PAH concentrations occurred w…
Variation in Sr uptake in the shell of the freshwater gastropod Bithynia tentaculata from Lake Arreo (northern Spain) and culture experiments
2010
The Sr uptake features in Bithynia tentaculata aragonite shells from monthly collections in Lake Arreo (northern Spain) over a two-year period are compared with those from the same species grown in culture experiments with similar waters under controlled temperature. The shell aragonite of B. tentaculata from Lake Arreo formed in isotopic equilibrium with the lake water. A comparison of the stable oxygen isotope values (δ18O) from the shells and waters allowed the selection of suitable shells for Sr uptake studies. The Sr/Ca molar ratio in B. tentaculata shells (Sr/Cashell) from the lake and from the culture experiments positively correlate with some chemical parameters like conductivity an…
Study of the neutral pion and direct photon production in Au+Au collisions at √sNN = 39-200 GeV
2013
This thesis focuses on the study of the neutral pion and eta production in the Au+Au “low-energy”collisions at √sNN = 39 and 62.4 GeV.The η/π0 ratio was reconstructed in Au+Au minimum bias collisions at √sNN = 62.4 GeV up to pT < 7 GeV/c. The direct photons were reconstructed via the subtraction method using two different PID cuts up to pT < 10 GeV/c in Au+Au minimum bias collisions at √sNN = 62.4 GeV.

Underground investigation of extensive air showers spectra at high energy range of cosmic rays and other research in the Pyhäsalmi mine
2020
Abstract High energy particles reaching the Earth’s atmosphere are known as cosmic rays. As a result of interactions with nuclei of air molecules, cosmic rays induce showers of secondary particles, which can be divided into 3 components: electromagnetic, hadronic and muonic components. The Experiment with Multi Muon Array (EMMA), located at the depth of 75 m in the Pyhäsalmi mine in Finland, investigates the muonic component of the Extensive Air Showers (EAS) to deduce the direction, energy, and the mass of the primary cosmic ray particles. In this paper we give a concise description and methodology used by EMMA followed by a brief review of the C14 experiment. Finally, we review the feasib…
