REE, Uranium (U) and Thorium (Th) contents in Betula pendula leaf growing around Komsomolsk gold concentration plant tailing (Kemerovo region, Western Siberia, Russia)

The article deals with the research findings of peculiarities of REE, Uranium and Thorium distribution in the territory surrounding the tailing of former Komsomolsk gold concentration plant according to the data from Betula pendula leaf testing. In the leaf element composition the slight deficiency of MREE and substantial excess of HREE are presented. In the nearest impacted area around the tailing, La, Yb, U and Th content, and Th/U ratio are lower than in the distant buffer area. It is shown, that value of Th/U ratio and REE can be an indicator for geochemical transformations of technogenic landscapes in mining districts. The results of the research can be used for biomonitoring of the territory around the tailing

Kvinners erfaringer med abortnemnder

Denne rapporten presenterer resultatene fra en amfunnsvitenskapelig studie om kvinners erfaringer med abortnemnder. Rapporten bygger på 13 dybdeintervju med kvinner som hadde erfaring med å søke om og gjennomleve andretrimesterabort innenfor et abortnemndsystem. Kvinnene hadde fått sine abortbegjæringer behandlet i nemnd ved åtte ulike sykehus i hele landet. Studien undersøkte kvinnenes helhetlige prosess med å søke andretrimesterabort innen rammene av et abortnemndsystem, opplevelser knyttet til selve møtet med nemnden og kvinnenes erfaringer knyttet til nemndenes myndighet til å fatte beslutning om deres liv samtidig som de skal ivareta kvinnenes rett til informasjon og veiledning. Kvinnene fortalte sine historier fra de oppdaget svangerskapet til tiden etter at abortfødsel var overstått. Analysen som presenteres i denne rapporten fokuserer på temaene 1) Forventninger og forberedelser til nemndsmøtet, 2) Å møte abortnemnden og 3) Tidsrammer og oppfølging. Studien viser at tiden før selve nemndsmøtet preges av varierende forkunnskaper og ulik og mangelfull informasjon til kvinnene om plikter og rettigheter ved nemndsbehandling. Muligheten for å få avslag preget kvinnene i forkant av nemndsmøtet, og gjorde kvinnenes beslutningsprosess vanskeligere. Videre viser studien at abortnemndene organiseres svært ulikt fra sykehus til sykehus. Noen kvinner opplevde at nemnden ga råd og støtte utover det å avklare om aborten oppfylte lovens kriterier. Mens noen opplevde nemndsmøtet som både belastende og meningsløst, opplevde andre det som en støtte. Metaforer som «eksamen» eller «avhør» ble brukt til å beskrive noen av kvinnenes møte med nemnden. Kvinner som hadde søkt om å få avslutte et ønsket svangerskap var frustrert over at partner ikke hadde plass som part i nemndsystemet. Tidsaspektet formet kvinnenes opplevelser med nemndsbehandling. For noen var det å vente på nemnden en belastning. For andre gjorde lovens grenser for svangerskapets avslutning at vanskelige avgjørelser måtte tas på kort tid. Kvinnene hadde et stort behov for støtte og oppfølging etter abortfødsel, og i dag er det ikke noe system som sikrer dette. Abortnemndene utgjør bare én del av et større system som aktiveres når en kvinne søker en andretrimesterabort. Kvinnenes erfaringer med abortnemndsystemet preges av skjevheten i makt mellom dem selv og nemnden. Denne skjevheten begrenser rommet for tvil og muligheten for en god og opplysende dialog. Noen kvinner opplever at møtet med nemnd gir dem større kontroll over egen situasjon. Slik det fungerer i dag favoriserer nemndsystemet ressurssterke kvinner og kan bidra til å ytterligere marginalisere sårbare kvinner. Uklarhet og ulik praksis knyttet til abortnemndens oppgave utover det å fatte et vedtak om andretrimesterabort, skaper risiko for at viktig informasjon ikke formidles. Dette svekker kvinners rett til å ikke delta i nemndsmøte samt hennes mulighet til å handle på bakgrunn av riktig informasjon. Dagens system tar i liten grad høyde for at de fleste andrestrimesteraborter er avbrudd av ønskede svangerskap. For kvinner som opplever dette virker abortnemdsystemet fremmedgjørende og lite forståelsesfullt. Dette kan gjøre den vanskelige tiden etter en gjennomført abort ekstra krevende. Dagens helsesystem sikrer ikke god oppfølging til kvinnene som gjennomgår en andretrimesterabort. Tiden etter en gjennomført abortfødsel er den mest sårbare for kvinnene som har vært gjennom abortnemndsystemet. Det er grunn til å stille spørsmål til ressursbruken knyttet til nemndsmøtene i kontrast til få ressurser til oppfølgingstjenester

Memories of being injured and patients' care trajectory after physical trauma

<p>Abstract</p> <p>Background</p> <p>The purpose of this study was to acquire a deeper understanding of patients' memories of being injured and the trajectory of care before, during and after their Intensive Care Unit (ICU) stay.</p> <p>Methods</p> <p>Interviews were conducted with eighteen informants who after physical trauma had been cared for in the ICU. The interviews were analyzed by using a phenomenological hermeneutical method.</p> <p>Results</p> <p>The memories of injury during the trajectory of care are illustrated in a figure in which the injured informants have memories from five scenes; the scene of the accident, emergency unit, ICU, nursing ward and of coming home. Twelve subthemes were abstracted and four themes emerged; a surrealistic world, an injured body, care, and gratitude for life. After the accident, a "surrealistic world" appeared along with bad memories of being in a floating existence where plans had to be changed. This world was unfamiliar, sometimes including delusional and fragmentary memories from the ICU, and it was experienced as uncontrollable. They felt connected to an "injured body", experiencing bad memories from the ICU of being injured, from the nursing ward of simply enduring and of being in a No Man's Land when coming home; their lives had become limited. At the same time they were "connected to care" with good memories of receiving attention from others at the scene of the accident, being taken cared of at the emergency unit and cared for in the ICU. This care made them realise that people are responsible for each other, and they felt comforted but also vulnerable. Finally, they experienced "gratitude for life". This included good memories of being loved together with support from their families at the ICU, wanting to win life back at the nursing ward and acceptance when returning home. The support from their families made them realise that they fit in just as they are.</p> <p>Conclusion</p> <p>When bad memories of a surrealistic world and of being injured are balanced by good ones of care and love with a gratitude for life, there are more possibilities to move on despite an uncertain future following the injury.</p

Cancer worry among Norwegian male BRCA1/2 mutation carriers

This qualitative study explored the experiences of Norwegian men after being identified as BRCA 1/2 mutation-positive. Only limited knowledge is available on this topic; therefore, the aim of this study was to gain a deeper insight from the men’s own perspectives. Data were collected from in-depth interviews with 15 men and seven of their partners. The participants described fear of cancer development, and two main narrative patterns were identified: fear for their own health, including fear of developing cancer, and negative feelings about responsibility for others’ health. The men expressed fear of developing cancer themselves and described a need for genetic risk information. They were also deeply concerned about how the mutation might affect their children and other relatives. There is a need for guidelines concerning genetic risk information and follow-up programs for male BRCA 1/2 mutation carriers. This study adds valuable contextual insights into their experiences of living with fear of cancer

Interaction with potential donors' families: The professionals' community of concern—a phenomenological study

The aim of this paper was to explore the health professionals' experiences and gain a deeper understanding of interaction with families of critically ill or traumatized patients with severe brain injuries. The methodological approach was qualitative and phenomenological. Data were collected through participant observation and in-depth interviews with nurses, physicians, and chaplains working in two ICUs in a Norwegian university hospital. A thematic analysis was used for analyzing data. Two main themes emerged from analysis: Patient oriented even when present and Family oriented even when absent. Each main theme is divided into two sub-themes. The themes appeared as phases in an interaction process. In the two first phases the interaction may be characterized as Alternating between being absent and present and Following up and withholding information and in the two last phases as Turning point and changing focus and Partly present when waiting for death. The findings are in the discussion illuminated by the phenomenological concept of concern. Concern is visible as care, and the distinction in care between “leaps in” and “leaps ahead” and “ready-to-hand” and “unready-to-hand” are topics in the discussion. Because of the complexity of caring for both patient and family, the situation demands efforts to relieve nurses in particular, during the most demanding phases of the process

Large-scale unit commitment under uncertainty: an updated literature survey

The Unit Commitment problem in energy management aims at finding the optimal production schedule of a set of generation units, while meeting various system-wide constraints. It has always been a large-scale, non-convex, difficult problem, especially in view of the fact that, due to operational requirements, it has to be solved in an unreasonably small time for its size. Recently, growing renewable energy shares have strongly increased the level of uncertainty in the system, making the (ideal) Unit Commitment model a large-scale, non-convex and uncertain (stochastic, robust, chance-constrained) program. We provide a survey of the literature on methods for the Uncertain Unit Commitment problem, in all its variants. We start with a review of the main contributions on solution methods for the deterministic versions of the problem, focussing on those based on mathematical programming techniques that are more relevant for the uncertain versions of the problem. We then present and categorize the approaches to the latter, while providing entry points to the relevant literature on optimization under uncertainty. This is an updated version of the paper "Large-scale Unit Commitment under uncertainty: a literature survey" that appeared in 4OR 13(2), 115--171 (2015); this version has over 170 more citations, most of which appeared in the last three years, proving how fast the literature on uncertain Unit Commitment evolves, and therefore the interest in this subject

Uranium in Municipal Solid Waste Landfill Leachate

ABSTRACT: Landfill leachates and leachate sediments were investigated in order to survey the discharge of uranium (U) from municipal solid waste (MSW) landfills and municipal solid waste incinerator (MSWI) bottom ash landfills. Concentrations of U in the leachates were as high as or higher than concentrations of Cd, a metal more often discussed when considering the environmental effects of landfill leachate. However, the U concentrations in leachate were no greater than levels occurring naturally in water. The U concentrations in leachate sediments were also the same as or lower than those reported in lake sediments around the world. Size charge fractionation of U in freshly sampled leachate showed that the metal was present mainly as either non-labile dissolved complexes or free anions, which have intermediate to high mobility and eco-toxicity. This is in contrast to other heavy metals, such as Cd, which are generally particulate bound in leachate. However, based on all the results of the investigations, it was concluded that leaching of U is not of major concern in MSW and MSWI bottom ash landfills
