Influence of abiotic environmental factors on Pelargonium graveolens growth
2018
Ekstrakty pozyskiwane z roślin były używane, zwłaszcza w medycynie naturalnej, już od czasów antycznych. Przeprowadzono wiele badań, które dowodzą różnokierunkowych właściwości olejków eterycznych. Ten pozyskiwany z Pelargonium graveolens jest jedną z najbardziej cenionych substancji dla różnych gałęzi przemysłu, takich jak: kosmetyczna, mydlarska, perfumeryjna, aromaterapeutyczna, spożywcza czy medyczna. P. graveolens należy do rodziny Geraniaceae i zawiera około 280 gatunków różniących się morfologią i wyglądem zewnętrznym. Bylina ta jest krzewem sięgającym 1,3 m wysokości i ok. 1 m szerokości. Jest rodzima dla regionu Cape w południowej Afryce, natomiast została rozpowszechniona na więks…

Educational attainment and permanence in NEET situation among youth
2018
Using the French Labour Force Survey, this paper analyses the individual and institutional effects on the transitions into and out of NEET status before and after the crisis. In particular, we question whether the profiles or the labour market transition patterns of young people have changed since the economic crisis. The econometric results indicate that the NEET risks vary according to age, sex, educational level and social origins. They also show that the transition out of NEET status is more related to the educational attainment, after 2008. Conversely, the lack of human capital and social capital increases the retention of youth in NEET situations.
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…
Inference of proto-neutron star properties from gravitational-wave data in core-collapse supernovae
2021
The eventual detection of gravitational waves from core-collapse supernovae (CCSN) will help improve our current understanding of the explosion mechanism of massive stars. The stochastic nature of the late post-bounce gravitational wave signal due to the non-linear dynamics of the matter involved and the large number of degrees of freedom of the phenomenon make the source parameter inference problem very challenging. In this paper we take a step towards that goal and present a parameter estimation approach which is based on the gravitational waves associated with oscillations of proto-neutron stars (PNS). Numerical simulations of CCSN have shown that buoyancy-driven g-modes are responsible …
Bērnu un jauniešu nometņu iekšējā pārvaldības sistēma
2019
Kvalifikācijas darba „Bērnu un jauniešu nometņu iekšējā pārvaldības sistēma” mērķis ir aprakstīt darba autores vadītu nometņu un to dalībnieku pārvaldības sistēmu, kas ļautu ērti pārvaldīt dalībnieku pieteikšanos nometnēm, dalībnieku informāciju un informāciju par notikušajām un paredzētajām nometnēm. Sistēmas galvenais nolūks ir automatizēt dalībnieku pieteikšanos nometnēm un tādējādi būtiski atvieglojot un samazinot laika patēriņu nometnes organizēšanai. Sistēma ļautu nometnes darbiniekiem – organizatoriem pārvaldīt informāciju par nometnēm, to dalībniekiem un atbalstītājiem. Nometņu dalībnieki varētu apskatīt aktuālāko informāciju, pieteikties paredzētajām nometnēm un arī atteikties no d…
Evidence of energy and nutrient transfer from invasive pink salmon (Oncorhynchus gorbuscha) spawners to juvenile Atlantic salmon (Salmo salar) and br…
2021
Recent large influxes of non‐native Pacific pink salmon (Oncorhynchus gorbuscha) to North European rivers have raised concern over their potential negative impacts on native salmonids and recipient ecosystems. The eggs and carcasses of semelparous pink salmon may provide a significant nutrient and energy subsidy to native biota, but this phenomenon has not been widely documented outside the species' native distribution. We analysed the stomach contents and stable isotope values (δ15N and δ13C) in muscle and liver tissues of juvenile Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) to determine whether these native salmonids utilise marine‐derived nutrients and energy provided by…
La spada penale trafigge i rave party. Osservazioni attorno al nuovo reato di “Invasione di terreni o edifici per raduni pericolosi” (art. 434 bis c.…
2022
Il contributo analizza i profili critici della norma "anti rave party" introdotta con il Decreto Legge n. 162/2022 e ne valuta le possibili modifiche, alla luce della proposta di emendamento di recente presentata dall'Esecutivo con l'obiettivo di "normalizzare" la disposizione.
Benthic‐pelagic coupling and trophic relationships in northern Baltic Sea food webs
2020
Understanding marine ecosystem structure and functioning is crucial in supporting sustainable management of natural resources and monitoring the health of marine ecosystems. The current study utilized stable isotope (SI) mixing models and trophic position models to examine energy flow, trophic relationships, and benthic‐pelagic coupling between food web components. Roughly 1900 samples from different trophic levels in the food web, collected during 2001–2010 from four northern and central sub‐basins of the Baltic Sea, were analyzed for SI ratios of carbon and nitrogen. Trophic structure of the food webs among the sub‐basins was consistent, but there were differences between the proportions …
Ceļojumu naratīvu lingvistiskā analīze
2021
Ceļojumu literatūra ir informatīva un izklaidējoša, tomēr pētnieki kā Lisle, Tompsons, Azaraija u.c. uzskata to arī par ideoloģiski piesātinātu. Pētījuma mērķis bija noteikt, vai izvēlētajam tekstuālajam materiālam no C. Tompsona ceļojumu memuāra ir ideoloģizēta teksta pazīmes. Empīriskā analīze tika veikta, balstoties uz piecām diskursīvām stratēģijām, kas ir nosaukšanas, apgalvošanas, argumentācijas, perspektivizācijas, pastiprināšanas vai mīkstināšanas stratēģijas, galveno uzmanību pievēršot tādam lingvistiskam materiālam kā lietvārdi, īpašības vārdi un darbības vārdi, kurus visbiežāk izmanto, lai ideoloģizētu stāstītās situācijas un notikumus. Pētījuma dati liecina, ka izmantotās lingvi…
