Mode I interlaminar fracture toughness of thin-ply laminates with CNT webs at the crack interface
2019
Abstract Pristine and functionalized carbon nanotube (CNT) webs were introduced at the interlaminar region of two different thin-ply carbon fibre reinforced polymer systems (NTPT 402 prepreg, and TeXtreme/SE84LV). The Mode I interlaminar fracture toughness (ILFT) for the NTPT 402 material was substantially lower. In contrast when SE84LV resin was used, the resistance curves were virtually unchanged and with no depreciation in the steady state value of the ILFT. This demonstrates that a careful choice of the resin is essential to permit the embedding of CNT webs in thin-ply laminates without compromising structural performance and opens a new way towards the development of multifunctional th…
Simulated eutrophication and browning alters zooplankton nutritional quality and determines juvenile fish growth and survival
2018
Source at https://doi.org/10.1002/ece3.3832. The first few months of life is the most vulnerable period for fish and their optimal hatching time with zooplankton prey is favored by natural selection. Traditionally, however, prey abundance (i.e., zooplankton density) has been considered important, whereas prey nutritional composition has been largely neglected in natural settings. High‐quality zooplankton, rich in both essential amino acids (EAAs) and fatty acids (FAs), are required as starting prey to initiate development and fast juvenile growth. Prey quality is dependent on environmental conditions, and, for example, eutrophication and browning are two major factors defining primary produ…
Jautājumu veidi uzņēmumu mājas lapās
2018
Uzņēmumiem mājaslapas ir nozīmīgs komunikācijas kanāls, kas klientiem ļauj uzzināt nepieciešamo informāciju visā mājaslapā vai ‘Biežāk uzdotie jautājumi’ un ‘Palīdzība’ sadaļās, kur atrodamas atbildes uz dažādiem jautājumiem. Pētījuma mērķis bija veikt jautājumu analīzi un salīdzināt to lietojumu mazumtirdzniecības un banku mājaslapās. Izpētes procesā tika pielietota diskursa analīze. Rezultāti norāda, ka banku mājaslapas satur vairāk jautājumu nekā mazumtirdzniecības mājaslapas, tomēr noteikta veida jautājumi – wh-/how jautājumi, plašais modālo palīgdarbības vārdu can un will, kā arī tagadnes laika lietojums jautājumu formēšanā bija līdzīgas valodu iezīmes abu sfēru mājaslapās.

Corporate online presence : a study of eight Finnish exporting companies' corporate websites
2012
Yritykset käyttävät verkkosivujaan tuotteiden ja palveluiden markkinoinnin ohella myös yrityksen mainostamiseen ja verkkoidentiteetin luomiseen. Verkkoidentiteetti heijastaa kielen ja visuaalisen ilmeen kautta yrityksen identiteettiä sekä tavoiteltua yrityskuvaa. Tutkimuksen tavoitteena oli selvittää kriittisen diskurssianalyysin avulla millä tavalla suomalaiset vientiyritykset ilmentävät verkkoidentiteettiään sekä kielellisesti että visuaalisesti yritysprofiileissaan. Yritysprofiilit rakentuvat yritystarinoista, joiden tehtävänä on esitellä keskeisiä asioita yrityksestä ja samalla rakentaa tietynlaista kuvaa yrityksestä. Verkkoidentiteetin lisäksi tarkoituksena oli selvittää onko yritystar…

Marine food web perspective to fisheries‐induced evolution
2021
Abstract Fisheries exploitation can cause genetic changes in heritable traits of targeted stocks. The direction of selective pressure forced by harvest acts typically in reverse to natural selection and selects for explicit life histories, usually for younger and smaller spawners with deprived spawning potential. While the consequences that such selection might have on the population dynamics of a single species are well emphasized, we are just beginning to perceive the variety and severity of its propagating effects within the entire marine food webs and ecosystems. Here, we highlight the potential pathways in which fisheries‐induced evolution, driven by size‐selective fishing, might reson…
A New Method to Reconstruct Quantitative Food Webs and Nutrient Flows from Isotope Tracer Addition Experiments
2020
Understanding how nutrients flow through food webs is central in ecosystem ecology. Tracer addition experiments are powerful tools to reconstruct nutrient flows by adding an isotopically enriched element into an ecosystem and tracking its fate through time. Historically, the design and analysis of tracer studies have varied widely, ranging from descriptive studies to modeling approaches of varying complexity. Increasingly, isotope tracer data are being used to compare ecosystems and analyze experimental manipulations. Currently, a formal statistical framework for analyzing such experiments is lacking, making it impossible to calculate the estimation errors associated with the model fit, the…

Lowered nutritional quality of prey decrease the growth and biomolecule content of rainbow trout fry
2022
Diet quality is crucial for the development of offspring. Here, we examined how the nutritional quality of prey affects somatic growth and the lipid, carbohydrate, protein, amino acid, and polyunsaturated fatty acid content of rainbow trout (Oncorhynchus mykiss) fry using a three-trophic-level experimental setup. Diets differed especially in their content of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are physiologically essential polyunsaturated fatty acids for a fish fry. Trout were fed with an artificial diet (fish feed, DHA-rich), marine zooplankton diet (krill/Mysis, DHA-rich), or freshwater zooplankton diet (Daphnia, Cladocera, DHA-deficient). The Daphnia were gr…
