Phenolic compounds and abscisic acid as potential markers for the floral origin of two Polish unifloral honeys

2012

The phenolic profiles of Polish honey samples from heather (Calluna vulgaris L.) and buckwheat (Fagopyrum esculentum L.) were determined. The phenolic components were isolated from honey samples using Amberlite-XAD-2 as a solid-phase extraction sorbent. For the determination of the composition of the honey extracts HPLC with photodiode array detector was applied. Identification and quantification of phenolics was performed by comparison of their retention times and UV spectra with those of standard solutions of pure reference substances and by using those references as external standards. From among 20 commercially available standards over 15 of them were identified as present in all analys…

Chemometrics as a Tool of Origin Determination of Polish Monofloral and Multifloral Honeys

2014

The aim of this study was to evaluate the application of chemometrics studies to determine the botanical origin of Polish monofloral honeys using NMR spectroscopy. Aqueous extracts of six kinds of honeys, namely, heather (Calluna vulgaris L.), buckwheat (Fagopyrum esculentum L), lime (Tilia L), rape (Brassica napus L. var. napus), acacia (Acacia Mill.), and multifloral ones, were analyzed. Multivariate chemometric data analysis was performed using principal component analysis (PCA) and orthogonal partial least-squares discriminant analysis (OPLS-DA). Chemometric analysis supported by pollen analysis revealed the incorrect classification of acacia honeys by the producers. Characteristic moti…

Diurnal Variation of Non-Arboreal Pollen in the Air in Finland

1981

Abstract This study was carried out in Jyvaskyla and Turku, in central and southern Finland, with Burkard spore traps. The average diurnal variation of all non-arboreal pollen types found in sufficient quantities is presented. A high concentration of Artemisia pollen lasting 4–8 hours was found mainly in the morning. The highest concentrations of Brassicaceae, Calluna, Cyperaceae and Rosaceae occurred during the daylight hours, often with no definite peaks. The peak occurrence of Chenopodiaceae, Compositae and Plantago pollen was around 12.00 and of Rumex from 06.00 to 10.00. The diurnal variation of Poaceae pollen varies considerably depending on the species flowering at the time. Peaks oc…

From the Strait of Gibraltar to northern Europe: Pleistocene refugia and biogeographic history of heather (Calluna vulgaris, Ericaceae)

2021

Abstract Calluna vulgaris (Ericaceae) is the most widespread and prevalent woody species of the European dry heathland, from the African side of the Strait of Gibraltar to northern Europe. However, previous biogeographic analyses of this species have ignored the western Mediterranean region, despite its preponderant role as a major glacial refugium for European biota. Here, we explore the existence of further Pleistocene glacial refugia for C. vulgaris in the Iberian Peninsula and the Strait of Gibraltar area and provide new insights into the post-glacial colonization of Europe by this emblematic heathland species. We carried out phylogeographical analyses of C. vulgaris samples from 44 loc…

Programa Lluna: talleres de sexo y consumo más seguro en el medio penitenciario (1995-2001)

2002

En el trabajo se expone someramente un programa educativo para la prevención del VIH/Sida consistente en una oferta anual de talleres sobre sexo y consumo de drogas que ha ido evolucionando con buenos resultados y en donde, se basan distintos grupos de autoayuda según características de practica sexual parejas, hombres/mujeres solos. hetero/homosexuales). En este programa intervienen distintos colaboradores profesionales. voluntarios. y los mediadores surgidos y formados en el mismo medio penitenciario, estos últimos de probada eficacia. Los cambios de actitudes en las relaciones humanas y las medidas profilácticas básicas, son la base del mismo. Se exponen los contenidos de los talleres, t…

Noticing-prefaced recoveries of the interactional space in a video-mediated business meeting

2020

Drawing on conversation analysis and authentic data from a video-mediated multiparty meeting, this study investigates the sequential and temporal organisation of recoveries of the interactional space. It focuses on moments in which either an auditory or a visual barrier emerges, and the participants orient to these troubles through intensified bodily-visual displays: embodied noticings. The analysis illustrates noticing-prefaced recoveries of the interactional space as procedural and multimodal accomplishments that require close attentiveness to the co-participants’ verbal and visual conduct and to the contingencies of the meeting. The study highlights not only the affordances of video-medi…

Oppilaiden kaikupuheen tehtävät kielellisesti epäsymmetrisissä luokkahuonekeskusteluissa

2017

Repeating the words of the conversational partners gives the persons with restricted communicative abilities a possibility for taking an active part in and exerting some control in the conversational interaction. Earlier research has approached the repeats with two different viewpoints: they have been considered either as problematic and meaningless echolalia, or as motivated communication meaningful for speakers themselves. This paper examines the functions for which students with special needs use repetition in their interaction with teachers and the ways in which teachers treat these echolalic responses in classroom talk. The research data consists of the video-recordings of lessons in o…

Density functional theory description of random Cu-Au alloys

2019

Density functional alloy theory is used to accurately describe the three core effects controlling the thermodynamics of random Cu-Au alloys. These three core effects are exchange correlation (XC), local lattice relaxations (LLRs), and short-range order (SRO). Within the real-space grid-based projector augmented-wave (GPAW) method based on density functional theory (DFT), we adopt the quasinonuniform XC approximation (QNA), and take into account the LLR and the SRO effects. Our approach allows us to study the importance of all three core effects in a unified way within one DFT code. The results demonstrate the importance of the LLR term and show that going from the classical gradient level a…

Multimodal accomplishment of alignment and affiliation in the local space of distant meetings

2017

Technology-mediated (i.e. distant) meetings are complex settings that involve distributed participation frameworks and the coordination of actions in multiple interactional spaces. This paper examines how problems with hearing, speaking, or understanding in the overall meeting space enable the negotiation of alignment and affiliation by co-present participants in the same local meeting space. Conversation analysis is used to investigate the local accomplishment of alignment and affiliation achieved through the sequential and temporal organization of verbal, embodied, and material resources of interaction in three types of situations: during technological trouble, silences, and disagreements…
