Identification of carbonaceous geosorbents for PAHs by organic petrography in river floodplain soils.
2007
Organic petrographic analysis was applied to provide direct information on carbonaceous geosorbents for PAHs in river floodplain soils. The anthropogenic OM group (primarily coal and coal-derived particles) displayed large volume amounts for all the soil samples. Distinct PAH concentrations with similar PAH distribution patterns were determined in grain size and density fractions for each sample. Two-ring PAHs had stronger correlation to organic carbon (OC) than black carbon (BC) contents, while heavier PAHs showed correlation to BC, rather than OC. In this study, we combined grain size and density separation, PAH determinations, TOC and BC measurements, and organic petrographic identificat…
Occurrence of coal and coal-derived particle-bound polycyclic aromatic hydrocarbons (PAHs) in a river floodplain soil.
2006
A PAH contaminated river floodplain soil was separated according to grain size and density. Coal and coal-derived particles from coal mining, coal industry and coal transportation activities were identified by organic petrographic analysis in our samples. Distinct concentrations of PAHs were found in different grain size and density fractions, however, similar distribution patterns of PAHs indicated similar sources. In addition, although light fractions had the mass fraction by weight of less than 5%, they contributed almost 75% of the total PAHs in the soil. PAH concentrations of all sub fractions showed positive correlation with their TOC contents. Altogether, coal and coal-derived partic…
Comparison of the Phytotoxkit microbiotest and chemical variables for toxicity evaluation of sediments
2006
The main objective of the research was to evaluate the suitability of the Phytotoxkit microbiotest as a tool for hazard assessment of sediments. The concentrations of oil derivatives, polycyclic aromatic hydrocarbons (PAHs), and heavy metals (Cd, Cr, Cu, Hg, Ni, Pb, and Zn) were determined in sediment samples collected from the urban canal in Opole (Poland), in order to obtain a general insight of the level of sediment contamination. Phytotoxicity of sediments was estimated on the basis of seed germination and root elongation measurements, combined into an overall germination index (Gl). The results revealed spatial and vertical differentiation in sediment contamination. A good correlation …
On the Relationship Between “Education” and “Critical Thinking”
2019
In view of recent international efforts to identify and measure the ability “critical thinking,” this paper attempts to trace and reconstruct the core meaning of this concept in the light of its conceptual history in the German terminology of educational philosophy and research. In doing so, it becomes evident that it is necessary to clarify the relationship between “critical thinking” and “education,” both understood as terms designating a mental state. In German as well as in English educational research, it seems to be the prevailing view that “critical thinking” is a partial meaning, a facet, of “education” (in the sense of “being well educated”). The German language, however, different…
Love, joy and necessity - A phenomenological study of food and meals in adolescents and young adults with cancer receiving high-emetogenic chemothera…
2021
Abstract Purpose This study explored how the phenomenon of meals appeared in the interrelationship between adolescents and young adults (AYAs) receiving high-emetogenic chemotherapy, their next of kin and health professionals in the clinical setting. Method Data were collected by 140 h of participant observation conducted to gain insights into the nature of how meals appeared in the interrelationship between 12 AYAs (age 15–29 years), their next-of-kin and health professionals. The AYAs were patients with oncological and haematological diseases recruited from three university hospital departments. Data analysis was guided by van Manen's hermeneutic-phenomenological approach. Results The ess…
HEALTH AND PHYSICAL FUNCTIONING AS DETERMINANTS OF PURPOSE IN LIFE IN OLD AGE
2018
AbstractPurpose in life reflects the feeling of having goals and meaning in life. Higher purpose in life has been shown to predict better health outcomes in old age and even buffer against mortality. However, it is not known how current health and functional status reflect on the possibilities of older people to live a meaningful life. Therefore, this study aimed to explore associations of health and physical functioning with purpose in life. The participants were 273 community-dwelling 75-year-old men and women from the AGNES study. Purpose in life was assessed with the subscale of the Scales of Psychological well-being (range 7–42). Current health situation and walking ability were self-r…
Chance and Causality in Ageing and Longevity
2019
Longevity is not a matter of genes. This is the message that appeared last year in all the newspapers of the world, according to a study due to a joint venture between the statisticians of Ancestry and Calico Life Sciences that has dissected the genealogical trees of 400 million individuals, tracing back generations, and including dates of birth, death, places, and family ties. The genes would have little to do with longevity: in a percentage perhaps even less than 10% [1]. However, this extensive study has analysed the influence of genetics in terms of lifespan, but not in terms of longevity. Longevity may be defined in relative and absolute terms [2]. Longevity, indeed, may be considered …
Espiritualidad en atención paliativa: Evidencias sobre la intervención con counselling
2015
ResumenLas necesidades espirituales, cuando son elaboradas de forma efectiva, ayudarán a la persona al final de la vida a encontrar significado, mantener la esperanza y aceptar la muerte. El counselling es una de las terapias más utilizadas para mejorar estas necesidades. El objetivo del presente trabajo es ofrecer evidencia sobre la eficacia de esta terapia para la mejora de la espiritualidad de los pacientes atendidos en diversos dispositivos de salud. Para conseguirlo, se llevó a cabo una intervención de tres semanas en 131 pacientes de atención domiciliaria y hospitalizados. Tenían una edad media de 70.61 años (DT = 11.17). El 51.1% eran hombres. Se evaluó la espiritualidad de los pacie…
Self-care and anticipated transition into retirement and later life in a Nordic welfare context
2011
Olle Söderhamn1–3, Anne Skisland1,2, Margaretha Herrman31Department of Health and Nursing Sciences, Faculty of Health and Sport Sciences, University of Agder, Grimstad and Kristiansand, Norway; 2Centre for Caring Research – Southern Norway, Grimstad, Norway; 3Department of Nursing, Health and Culture, University West, Trollhättan, SwedenAbstract: Few studies have appeared in the health care literature on the meaning of transition into retirement and later life. However, this predictable-involuntary transition may influence personal health and well-being, and studying it from a self-care perspective could be useful. The aim of this study was to illuminat…
Being old and living alone in urban areas: the meaning of self-care and health on the perception of life situation and identity
2013
- Published article -cc-by-nc Background: Living alone in urban areas when getting old is an important and necessary field for research as the growth of the urban population worldwide increases, and due to the fact that people live longer. How older people manage their self-care and health, and how this might influence their identity and life situation may be very important to understand when planning for a new, upcoming older generation. The aim of this study was to elucidate the meaning of self-care and health for the perception of life situation and identity among single-living older individuals in urban areas in southern Norway. Methods: A phenomenological–hermeneutic approach inspired …
