Przemysłowe zastosowanie pelargoniowego olejku eterycznego

2018

Od wielu lat ekstrakty roślinne, w tym olejki eteryczne wykorzystywane były nie tylko ze względu na ich walory zapachowe, ale także lecznicze. Mogą być one pozyskiwane z różnych części roślin, co wpływa na skład jakościowy pozyskanego olejku i wydajność wyjściowego materiału. Badania zawarte w tej pracy skupiają się na roślinach z rodzaju Pelargonium, obejmujący około 250 gatunków, a który jest bardzo ceniony ze względu na zawartość olejku eterycznego, wykorzystywanego w wielu gałęziach przemysłu, m.in. perfumerii, przemyśle kosmetycznym (m.in. mydła czy kremy) spożywczym czy farmaceutycznym. Pierwszym celem pracy było przedstawienie mnogości zastosowań pelargoniowego olejku, a także jego d…

Działanie pelargoniowego olejku eterycznego na Bacillus spp.

2018

Pelargonia pachnąca (Pelargonium graveolens) jest aromatycznym krzewem posiadającym jasnozielone, owłosione, miękkie w dotyku, karbowane liście i małe, różowe kwiaty. Należy do rodzaju Pelargonium (Geraniaceae) i liczy ponad 250 gatunków. Olejek eteryczny pozyskiwany z pelargonii jest bardzo ceniony nie tylko przez przemysł perfumeryjny czy aromaterapię, ale także przez przemysł spożywczy, kosmetyczny jak i farmację. Roczną produkcję olejku szacuje się na 300 ton. Liczne badania wskazują na jego silne właściwości przeciwbakteryjne, przeciwwirusowe, przeciwbólowe czy przeciwzapalne. Celem przeprowadzonych badań było określenie aktywności olejku pelargoniowego wobec Bacillus spp. Zebrano jedn…

A Complete, Exact and Efficient Implementation for Computing the Edge-Adjacency Graph of an Arrangement of Quadrics

2011

International audience; We present a complete, exact and efficient implementation to compute the edge-adjacency graph of an arrangement of quadrics, i.e. surfaces of algebraic degree 2. This is a major step towards the computation of the full 3D arrangement. We enhanced an implementation for an exact parameterization of the intersection curves of two quadrics, such that we can compute the exact parameter value for intersection points and from that the edge-adjacency graph of the arrangement. Our implementation is complete in the sense that it can handle all kinds of inputs including all degenerate ones, i.e. singularities or tangential intersection points. It is exact in that it always comp…

Seeing Gravity: Gait Adaptations to Visual and Physical Inclines – A Virtual Reality Study

2020

Using advanced virtual reality technology, we demonstrate that exposure to virtual inclinations visually simulating inclined walking induces gait modulations in a manner consistent with expected gravitational forces (i.e., acting upon a free body), suggesting vision-based perception of gravity. The force of gravity critically impacts the regulation of our movements. However, how humans perceive and incorporate gravity into locomotion is not well understood. In this study, we introduce a novel paradigm for exposing humans to incongruent sensory information under conditions constrained by distinct gravitational effects, facilitating analysis of the consistency of human locomotion with expecte…

"Suu on syömistä varten" : lasten ja aikuisten kohtaamisia ryhmäperhepäiväkodin ruokailutilanteissa

2006

Marjo Metsomäki tutki väitöskirjassaan lapsen ja aikuisen välisiä sekä lasten keskinäisiä valta- ja neuvottelusuhteita ryhmäperhepäiväkodin ruokailutilanteissa. Tutkimus osoitti ruokailutilanteiden olevan monimuotoisia, tilannesidonnaisia, vaihtuvia ja jatkuvasti liikkeessä olevia kohtaamistilanteita. Tulokset kiteytyivät kolmeen erilaiseen lapsen ja aikuisen väliseen kohtaamistyyppiin.Suhteemme ruokaan ja syömiseen muovautuvat vähitellen. Aikuiset vaikuttavat keskeisesti siihen, millaisen suhteen lapset luovat ruokaan, syömiseen ja ruumiiseensa ylipäänsä. Päivähoidon ruokailutilanteet ovat siten keskeisellä sijalla, kun mietitään sitä, miten voitaisiin vaikuttaa lasten syömiskäytäntöihin j…

Analysis of the traditional approaches for astronauts’ personal hygiene in outer space

2016

Various approaches adopted in the years for astronauts' personal hygiene in microgravity conditions are revisited and analysed in this paper. For each approach, benefits, critical aspects of sanitation and comfort, along with the possibility of recycling the amount of used water, are discussed and evaluated.

Empirical Verification of the Relationship Between Personality Traits and EFL Attainments

2023

Although the study of personality is one of the major themes in psychology, its role in the second language acquisition (SLA) process has not been unanimously acknowledged. The overall scarcity and obscurity of research outcomes can be attributed to methodological problems and lack of firm grounding in the vast field of personality theories. Moreover, it appears that personality may not exact an easily observable, direct effect on L2 behaviours and success. This paper is an attempt to broaden the understanding of the role of personality in the SLA field. Its main aim is to establish the predictive value of the personality dimensions (Neuroticism, Extraversion, Openness to experience, Agreea…

Paths from socioemotional behavior in middle childhood to personality in middle adulthood.

2012

Continuity in individual differences from socioemotional behavior in middle childhood to personality characteristics in middle adulthood was examined on the assumption that they share certain temperament-related elements. Socioemotional characteristics were measured using teacher ratings at ages 8 (N = 369; 53% males) and 14 (95% of the initial sample). Personality was assessed at age 42 (63% of the initial sample; 50% males) using a shortened version of the NEO Personality Inventory (NEO-PI); the Karolinska Scales of Personality (KSP); and the Adult Temperament Questionnaire (ATQ). Three models were tested using structural equation modeling. The results confirmed paths (a) from behavioral …
