It takes time to see the menu from the body: an experiment on stable isotope composition in freshwater crayfishes

2015

For many applications and ecological studies in which wild individuals are brought to laboratory it would be essential to know accurately how fast novel diet is reflected in composition of different tissues. To study the effects of two different diets on the stable isotope composition of freshwater crayfish muscle and hemolymph, we conducted a three month experiment on noble crayfish (Astacus astacus) and signal crayfish (Pacifastacus leniusculus) by feeding them sweet corn (Zea mays) or Baltic herring (Clupea harengus membras) as novel food. During the experiment, the crayfish were given 0.4 g of selected food daily and the amount consumed was recorded. The samples for the stable isotope a…

SOME EXAMPLES RELATED TO A CLASS OF FUNCTIONALS WITHOUT GLOBAL MINIMA

Abstract: In this paper, we provide six examples which show the sharpness of the assumptions of a recent deep result of Ricceri about a class of functionals without global minima.

Neural Classification of Compost Maturity by Means of the Self-Organising Feature Map Artificial Neural Network and Learning Vector Quantization Algo…

2019

Self-Organising Feature Map (SOFM) neural models and the Learning Vector Quantization (LVQ) algorithm were used to produce a classifier identifying the quality classes of compost, according to the degree of its maturation within a period of time recorded in digital images. Digital images of compost at different stages of maturation were taken in a laboratory. They were used to generate an SOFM neural topological map with centres of concentration of the classified cases. The radial neurons on the map were adequately labelled to represent five suggested quality classes describing the degree of maturation of the composted organic matter. This enabled the creation of a neural separator classify…

Diurnal Cycle Relationships between Passive Fluorescence, PRI and NPQ of Vegetation in a Controlled Stress Experiment

2017

In order to estimate vegetation photosynthesis from remote sensing observations; some critical parameters need to be quantified. From all absorbed light; the plant needs to release any excess that is not used for photosynthesis; by non-photochemical quenching; by fluorescence emission and unregulated thermal dissipation. Non-photochemical quenching (NPQ) processes are controlled photoprotective mechanisms which; once activated; strongly control the dynamics of photochemical efficiency. With illumination conditions increasing and decreasing during a diurnal cycle; photoprotection mechanisms needs to change accordingly. The goal of this work is to quantify dynamic NPQ; measured from active fl…

Direct Visualization of Molecule Deprotonation on an Insulating Surface

2012

Elucidating molecular-scale details of basic reaction steps on surfaces is decisive for a fundamental understanding of molecular reactivity within many fields, including catalysis and on-surface synthesis. Here, the deprotonation of 2,5-dihydroxybenzoic acid (DHBA) deposited onto calcite (101;4) held at room temperature is followed in situ by noncontact atomic force microscopy. After deposition, the molecules form two coexisting phases, a transient striped phase and a stable dense phase. A detailed analysis of high-resolution noncontact atomic force microscopy images indicates the transient striped phase being a bulk-like phase, which requires hydrogen bonds between the carboxylic acid moie…

Nuorten aikuisten tyypin 1 diabeetikoiden diabetes-spesifi elämänlaatu ja liikunta

2015

Tyypin 1 diabeetikoiden määrä kasvaa kansallisesti sekä kansainvälisesti. Sairauteen liittyy kysymyksiä varsinkin hoidon jatkuvaan ylläpitoon liittyen ja diabeetikoiden elämänlaadun on todettu olevan huonompaa verrattuna verrokkiväestöön. Liikunta aiheuttaa myös oman erityispiirteensä hoidon toimivuuteen. Tämän tutkimuksen tarkoituksena oli sekä kvantitatiivisesti, että kvalitatiivisesti selvittää sairaus-spesifiä elämänlaatua tyypin 1 diabeetikoiden osalta. Lisäksi tarkoituksena oli verrata fyysisen aktiivisuuden tasoa elämänlaatumittareihin sekä hoitotasapainoon. Tähän tutkimukseen kehitettiin kyselylomake ja aineisto (N=99; mediaani-ikä 22 v; 60.6% naisia) kerättiin yhteistyössä diabetes…

Efficiency of Daphnia magna in removal of green microalgae cultivated in Nordic recirculating aquaculture system wastewater

2020

The increase of global aquaculture production has boosted the development of recirculating aquaculture systems not only because they reduce water use but also provide opportunities for waste management and the use of released nutrients. The dissolved nutrients can be efficiently removed from recirculating aquaculture system wastewater by microalgae, and microalgae can be harvested from the wastewater with low costs by zooplankton such as Daphnia. The purpose of this study was to evaluate the feasibility of using microalgae and Daphnia for bioremediation of recirculating aquaculture system wastewater in Nordic conditions. We evaluated the growth and filtration efficiency of the waterflea Dap…

Laura Ruohosen näytelmä Sotaturistit pasifistisena satiirina

2019

Artikkelissani tutkin Laura Ruohosen Sotaturistit-näytelmää (2008) satiirin viitekehyksessä. Satiirille on tyypillistä selkeä kohde, johon kritiikki tai aggressio kohdistuu, sekä humoristinen ja leikittelevä käsittely ja muoto. Näytelmän historiallinen konteksti liittyy Krimin sotaan (1854–1856), ja sen keskiössä on ruotsalainen turistiryhmä, joka matkaa laivalla sotatapahtumien perässä. Sotaturistien perusjuoni on synkkä, mutta näytelmään syntyy komiikkaa etenkin kärjistettyjen henkilöhahmojen, koomisten tilanteiden ja hulvattoman dialogin välityksellä. Näytelmä alkaa huumorin sävyttämänä, mutta pikkuhiljaa sävyt synkkenevät, ja väkivalta alkaa kohdentua näytelmän keskeisiin henkilöihin. N…
