Carbon dynamics in highly heterotrophic subarctic thaw ponds

2015

Abstract. Global warming has accelerated the formation of permafrost thaw ponds in several subarctic and arctic regions. These ponds are net heterotrophic as evidenced by their greenhouse gas (GHG) supersaturation levels (CO2 and CH4), and generally receive large terrestrial carbon inputs from the thawing and eroding permafrost. We measured seasonal and vertical variations in the concentration and type of dissolved organic matter (DOM) in five subarctic thaw (thermokarst) ponds in northern Quebec, and explored how environmental gradients influenced heterotrophic and phototrophic biomass and productivity. Late winter DOM had low aromaticity indicating reduced inputs of terrestrial carbon, wh…

Metabolic plasticity of mixotrophic algae is key for their persistence in browning environments

2022

Light availability is the main regulator of primary production, shaping photosynthetic communities and their production of ecologically important biomolecules. In freshwater ecosystems, increasing dissolved organic carbon concentrations, commonly known as browning, leads to lower light availability and the proliferation of mixotrophic phytoplankton. Here, a mixotrophic algal species (Cryptomonas sp.) was grown under five increasing dissolved organic carbon concentrations to uncover the plastic responses behind the success of mixotrophs in browning environments and their effect in the availability of nutritionally important biomolecules. In addition to the browning treatments, phototrophic, …

Designing a graphics processing unit accelerated petaflop capable lattice Boltzmann solver: Read aligned data layouts and asynchronous communication

2017

The lattice Boltzmann method is a well-established numerical approach for complex fluid flow simulations. Recently, general-purpose graphics processing units (GPUs) have become available as high-performance computing resources at large scale. We report on designing and implementing a lattice Boltzmann solver for multi-GPU systems that achieves 1.79 PFLOPS performance on 16,384 GPUs. To achieve this performance, we introduce a GPU compatible version of the so-called bundle data layout and eliminate the halo sites in order to improve data access alignment. Furthermore, we make use of the possibility to overlap data transfer between the host central processing unit and the device GPU with comp…

4-5 gadīgu bērnu pašapziņas attīstības sekmēšana lomu rotaļā

2019

Darba autore - Agnese Kronberga. Bakalaura darba temats ir “ 4-5 gadīgu bērnu pašapziņas attīstības sekmēšana lomu rotaļā”. Pētījuma temata aktualitāti noteica gan moderno tehnoloģiju attīstība, pieprasot jebkuru cilvēku pielāgoties un adaptēties jaunā vidē, situācijā un informācijas plūsmā, gan 2018. gadā apstiprināto izglītības vadlīniju minētais mērķis- zinātkārs, radošs un dzīvespriecīgs bērns, un šo abu iepriekšminēto faktoru īstenošanai, autoresprāt, noteicoša iezīme ir pašapzinīga personība. Pētījuma mērķis ir teorētiski un praktiski pētīt 4-5 gadu vecu bērnu pašapziņas attīstības un pilnveides iespējas lomu rotaļās. Darbs sastāv no 2 nodaļām un 8 apakšnodaļām. Bakalaura darba pirmaj…

What does the translator do when she takes a moment? : scriptlog-aided analysis of long pauses and dictionary use in a translation process

2010

Käännösprosessin tutkiminen on viime vuosina siirtynyt yhä enemmän lopputekstin tutkimisesta itse prosessin eri osien ja piirteiden tutkimukseen. Tauot ovat yksi tämän prosessin eniten tutkituista piirteistä, mutta tähän asti tutkimukset ovat keskittyneet lähinnä kahden tai maksimissaan viiden sekunnin pituisten taukojen analysointiin. Tämän tutkielman tavoitteena on selvittää, millaista informaatiota käännösprosessin kulusta ja sisällöstä sekä sen kääntäjäkohtaisuudesta saadaan ottamalla tutkimuskohteeksi aiempia tutkimuksia pidemmät tauot sekä sanakirjojen käyttö käännösprosessin aikana. Tämän tutkielman aineisto kerättiin hyödyntämällä tietokoneohjelmaa nimeltä Scriptlog, joka tallentaa …

A new methodology to estimate deformation of longitudinal safety barriers

2013

The correct sizing of storage areas in the port areas is aimed to optimizing the management of intermodal transport and to ensure efficiency and functionality to the entire port system. In this paper is proposed a simulation model for design the port storage areas taking into account many parameters like: the service time, the randomness of the arrivals process, the storage capacity in terms of TEU that can be stored (and handled) in the unit of time. The capacity of the terminal warehouse is determined by the interrelation between fixed and static parameters in the short period which are: i) the extension of the storage area; ii) the height of the overlapping batteries of container (define…
