Different structural destinations: comparing reactions of [CuBr2(3-Brpy)2] crystals with HBr and HCl gas
2011
Reaction of green crystalline solid trans-[CuBr2(3-Brpy)2] 1 (3-Brpy = 3-bromopyridine) with HBr (aq) vapour yields brown crystalline salt (3-BrpyH)2[CuBr4] 2 with quantitative conversion. Notably 2 adopts a different crystal structure to the three mutually isostructural compounds (3-XpyH)2[CuCl4] (X = Cl, Br) and (3-BrpyH)2[CuBr2Cl2] which result from reaction with HCl. Crystalline product 2 has been characterised by X-ray powder diffraction and its conversion back to 1 at 370–400 K has been followed in situ by synchrotron X-ray powder diffraction. Crystalline 1 and 2 are further notable for the presence of intermolecular C–Br⋯Br–Cu halogen bonds and (only in the case of 2) N–H⋯Br–Cu hydro…
Multispectral autoflourescence detection of skin neoplasia using steady-state techniques
2019
In the current study were used excitation-emission matrices (EEMs) and synchronous fluorescence spectroscopy (SFS) steady-state techniques in a broad spectral regions (excitation at 220-500 nm and emission at 280-850 nm) to achieve the whole set of endogenous fluorophores, existed in normal and neoplastic cutaneous tissues. Several types of benign, dysplastic and malignant types of skin lesions were investigated ex vivo using both EEM and SFS modalities, namely the basal cell papilloma and carcinoma, pigmented nevi, dysplastic nevi, squamous cell carcinoma and malignant melanoma. Histological analysis was used as a “gold standard” for evaluation of clinical diagnosis of the lesions investig…
Characterization of oriented protein-ceramic and protein-polymer-composites for cartilage tissue engineering using synchrotron μ-CT
2007
Abstract In this paper we report on the synthesis of three different gelatine based scaffold materials for the reconstruction of articular cartilage defects. The first scaffold design is based on an unmodified, oriented gelatine network, while the second design further comprises an attached inorganic hydroxyapatite layer and the third design includes poly(l-lactide) microspheres as a model material for future drug-release applications. All three scaffold designs were characterized and imaged using synchrotron μ-CT, obtaining a complete volumetric reconstruction of a previously defined sample region. Furthermore, two unmodified scaffolds were cultivated for one week with porcine chondrocytes…
Nonverbal synchrony in couple therapy linked to clients’ well-being and the therapeutic alliance
2021
Nonverbal synchrony between individuals has a robust relation to the positive aspects of relationships. In psychotherapy, where talking is the cure, nonverbal synchrony has been related to a positive outcome of therapy and to a stronger therapeutic alliance between therapist and client in dyadic settings. Only a few studies have focused on nonverbal synchrony in multi-actor therapy conversations. Here, we studied the synchrony of head and body movements in couple therapy, with four participants present (spouses and two therapists). We analyzed more than 2000min of couple therapy videos from 11 couple therapy cases using Motion Energy Analysis and a Surrogate Synchrony (SUSY), a procedure us…
Multiscale variation in drought controlled historical forest fire activity in the boreal forests of eastern Fennoscandia
2017
Forest fires are a key disturbance in boreal forests, and characteristics of fire regimes are among the most important factors explaining the variation in forest structure and species composition. The occurrence of fire is connected with climate, but earlier, mostly local-scale studies in the northern European boreal forests have provided little insight into fire-climate relationship before the modern fire suppression period. Here, we compiled annually resolved fire history, temperature, and precipitation reconstructions from eastern Fennoscandia from the mid-16th century to the end of the 19th century, a period of strong human influence on fires. We used synchrony of fires over the network…
Reproducibility of Rolandic beta rhythm modulation in MEG and EEG
2022
The Rolandic beta rhythm, at ∼20 Hz, is generated in the somatosensory and motor cortices and is modulated by motor activity and sensory stimuli, causing a short lasting suppression that is followed by a rebound of the beta rhythm. The rebound reflects inhibitory changes in the primary sensorimotor (SMI) cortex, and thus it has been used as a biomarker to follow the recovery of patients with acute stroke. The longitudinal stability of beta rhythm modulation is a prerequisite for its use in long-term follow-ups. We quantified the reproducibility of beta rhythm modulation in healthy subjects in a 1-year-longitudinal study both for MEG and EEG at T0, 1 month (T1-month, n = 8) and 1 year (T1-ye…
Group synchronization of coordinated movements in a cross-cultural choir workshop
2009
Group synchronisation in choir performance was studied using motion capture. The choir consisted of South-African experts and Finnish novices. 4+4 participants’ movements were recorded during a performance of a traditional song and choreography. The aim of the study was to: 1) describe possible differences in movement implementation between the two groups; 2) investigate synchronicity between all participants and within and between each of the two groups; 3) visualise the dynamics of interpersonal influence. Preliminary results indicate that simple indicators such as cumulative distance and position as a function of time reveal differences in implementation of choreography between the group…
Neuere Fragestellungen in der Sprachinseldialektologie
2018
Language islands are the source of many interesting materials in the field of research on language contacts concerning longer time periods in diachronic and synchronous approaches. They are particularly valuable for the research on minority languages and their existence among the majority speaking another language. Wilamowice and Schönwald municipalities represent German language islands in Silesia that date back to the colonization in the Middle Ages. Their research makes it possible not only to analyze their relations with reference to another German dialects but also to capture a wider development mechanisms of language extinction processes as well as the forms of their integration with …
Ladinia dolomitica
2020
Scopo di questo contributo è offrire una panoramica sull’area che viene usualmente definita “Ladinia dolomitica” e sulla varietà linguistica che vi viene tradizionalmente parlata, il ladino. L'articolo descrive brevemente la storia dell'area e dello sviluppo del ladino, e in seguito descrive le caratteristiche fonologiche, morfologiche, sintattiche e lessicali principali del ladino, che lo distinguono dalle vicine varietà italoromanze. In seguito si illustrano le peculiarità linguistiche dei singoli dialetti ladini, che sono parlati ognuno in una valle diversa delle Dolomiti. L'articolo è fortemente innovativo e originale, perché permette di ascoltare i file audio che esemplificano i tratti…
