Use of Lichen and Moss in Assessment of Forest Contamination with Heavy Metals in Praded and Glacensis Euroregions (Poland and Czech Republic)
2011
The concentrations of selected metals-Cr, Ni, Cu, Zn, Cd, and Pb-were determined in the samples of Hypogymnia physodes lichen and Pleurozium schreberi moss collected in Polish and Czech Euroregions Praded and Glacensis. More specifically, the samples were collected in Bory Stobrawskie, Bory Niemodlińskie, and Kotlina Kłodzka (Poland) and in Jeseniki (Czech Republic). The concentration of metals in the samples was measured using the atomic absorption spectrometry (flame AAS technique and electrothermal atomization AAS technique). The results were used to calculate the comparison factor (CF) that quantifies the difference in concentration of a given bioavailable analyte × accumulated in liche…
Effects of tobacco smoke on indoor air quality: the use of mosses in biomonitoring.
2020
This research was carried out to assess the possibility of using Pleurozium schreberi mosses as bioindicators of atmospheric aerosol pollution in living quarters (kitchen and bedroom), with metals originating from tobacco smoke from various types of cigarettes: conventional cigarettes, e-cigarettes and heated tobacco products. The moss-bag method of active biomonitoring was used. The mosses were exposed in these indoor spaces for three months and, after the exposition period, their analytes – Ni, Cu, Zn, Cd and Pb – were determined using flame atomic absorption spectrometry (F-AAS). Results were interpreted using the relative accumulation factors (RAF), coefficients of variation (CV) and th…
A Paravermal Trans-Cerebellar Approach to the Posterior Fossa Tumor Causes Hypertrophic Olivary Degeneration by Dentate Nucleus Injury
2021
Background: In brain tumor surgery, injury to cerebellar connectivity pathways can induce a neurodegenerative disease called hypertrophic olivary degeneration (HOD), along with a disabling clinical syndrome. In children, cerebellar mutism syndrome (CMS) is another consequence of damage to cerebello&ndash
El management de las conductas socioemocionales. Una aproximación teórica y empírica desde el caso de los agentes de "contact centers"
2020
How is a specific type of emotion-related work conducts formed today? What principles guide these conducts and what effects do they have on those who work? The study of Contact Center agents allows us to understand how a set of personal qualities such as patience and good treatment of others, certain desires and personal impulses or even intimate sensations such as anguish or individual expectations have become managerialized emotions that end up modifying the inner attitudes of these agents. Within this framework, we propose a theoretical approach that integrates the work of Weber, Foucault and Elias, which invites us to reflect on a socio-emotional manner of leading one?s life (Lebensfu?h…

2015
Bakalaura darbs ir veltīts tēmai „Jutekliskās uztveres tematizācija Pētera Handkes stāstā Senviktuāra kalna mācība”. Darba mērķis ir izmeklēt un aplūkot Pētera Handkes jutekliskās uztveres atspoguļojumu stāstā Senviktuāra kalna mācība. Darba uzdevums ir izpētīt rakstnieka Pētera Handkes personību un viņa slaveno tetraloģiju, it īpaši tetraloģijas otro daļu. Darbs ir sadalīts trijās nodaļās. Pirmajā nodaļā tiek apskatīts un visparēji raksturots jēdziens „mūsdienu literatūra”, kā arī tiek apskatīta tā laika politiskā un sabiedriskā situācija Vācijā un Austrijā. Papildus tiek apskatīta mūsdienu rakstnieku paaudze un Pēters Handke tiek prezentēts kā mūsdienu vācu rakstnieku paaudzes populārs pā…
Varieties of agencies during working life changes
2020
The aim of this study is to shed light on the varieties of workers´ agencies in working life change situations, which is an under-researched topic in the literature of workplace learning and in working life studies. The research questions are what kinds of agencies there are to be found when workers encounter changes and how the different kinds of agencies are connected together. The understanding of agency is grounded on the subject-centered socio-cultural approach, whereas the methodological approach is based on applying life-course perspective on research material consisting of 48 working life narratives written by Finnish adults. The narratives are analyzed by abductive content analysis…
Análisis de los deberes del deporte en la universidad: ética cívica, derechos humanos, ética del deporte y fair play
2016
This article analyses the moral duties on the operation of the Sports Departments at Universities. Deontology, from the Greek Deon (duty) and logy (treated), refers to the sphere of duty. This ethical perspective, which is a key precursor from the German philosopher Immanuel Kant, raises the need to assume the duties that must be followed in interaction with others. In this sense the moral duties, as essential components of any code of ethics, guide the management model of Sports Departments at Universities. They have to undertake them in order to achieve its inner goal. Particularly, the article provides a panoramic analysis covering from the broadest to the most specific sources such as c…
On Some Statistical Properties of the Spatio-Temporal Product Density
2021
We present an extension of the non-parametric edge-corrected Ohser-type kernel estimator for the spatio-temporal product density function. We derive the mean and variance of the estimator and give a closed-form approximation for a spatio-temporal Poisson point process. Asymptotic properties of this second-order characteristic are derived, using an approach based on martingale theory. Taking advantage of the convergence to normality, confidence surfaces under the homogeneous Poisson process are built. A simulation study is presented to compare our approximation for the variance with Monte Carlo estimated values. Finally, we apply the resulting estimator and its properties to analyse the spat…
Caffeate and piperidine-3-ol derivatives from the stem bark of Cassia sieberiana
2019
A new caffeate derivative from the ethanol extract of the stem bark of Cassia sieberiana DC. is described herein along with the known secondary metabolites spectaline (2), iso-6-cassine (3), 3-O-methyl-chiro-inositol (4), monobehenin (5), octyl nonadecyloate (6), β-sitosterol (7), stigmasterol (8) and sitosterol 3-O-β-D-glucopyranoside (9). The chemical structures were elucidated by means of various spectroscopic and spectrometric techniques. Extract and isolated compounds were devoid of inhibitory action against the herein selected bacterial strains (MICs > 256 μg/mL) but showed capacities to reduce 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical (EC50 < 3 μg/mL) considerably better than the …
