ETEM, Environmental Transmission Electron Microscopy är en teknik som ger möjlighet att betrakta reaktioner mellan fasta föreningar, högsmältande vätskor och gaser i realtid, och med atomär upplösning.Ett Hitachi 3300S ETEM har designats och uppförts av nCHREM, the national Center for High Resolution Electron Microscopy vid Lund Universitet. Artikeln beskriver tekniska lösningar i systemet och de A new environmental transmission electron microscope has been installed in Lund in order to investigate the growth of III-V semiconductor nanowires by metal-organic chemical vapour deposition. We report here on the concepts behind the design of the facility and on details of the operation, and we refer to early results to highlight the new information that can be accessed from in situ studies. The

Seaweed cultivation is a large industry worldwide, but production in Europe is small compared to production in Asian countries. In the EU, the motivations for seaweed farming may be seen from two perspectives; one being economic growth through biomass production and the other being the provisioning of ecosystem services such as mitigating eutrophication. In this paper, we assess the economic potenSeaweed cultivation is a large industry worldwide, but production in Europe is small compared to production in Asian countries.

An introduction to the poetry of American poet Carolyn Forché (b. 1950) and Swedish translations of poems from her collection In the Lateness of the World (2020).

Background: To the authors' knowledge, few studies to date have examined long-term neurocognitive outcomes in survivors of childhood soft-tissue sarcoma. Methods: A total of 150 survivors (41% of whom were female with a mean current age of 33 years [SD, 8.9 years] and a time since diagnosis of 24 years [SD, 8.7 years]) and 349 community controls (56% of whom were female with a mean current age of

Purpose: To examine prevalence and predictors of neurocognitive outcomes, social attainment, emotional distress, and health-related quality of life (HRQOL) in long-term survivors of pediatric Wilms tumor (WT). Methods: One hundred fifty-eight WT survivors (59% female; mean [SD] age 33 [9.1] years; time since diagnosis 29 [9.1] years) and 354 community controls (55.6% female; 35 [10.2] years) compl

In the field of church history, this article is a study of the Reformation period on a specific topic, namely, asceticism, from an uncommon perspective. One of the most well-known Reformation treatises, Martin Luther’s On the Freedom of a Christian, is read in conversation with an earlier ascetic wri¬ting, Maximus Confessor’s The Ascetic Life, and then compared to an under¬stu¬died debate from the

Лише останніми роками інтелектуальна історія євгеніки в Східній Європі стала предметом систематичного академічного дослідження. Проте євгенічна думка в міжвоєнній українській радикально-націоналістичній традиції залишається історіографічною terra incognito. Ця стаття — перша спроба дослідження євгеніки й расової антропології в українській націоналістичній думці 1930—1960-х років. Яку роль відіграв

Praktisk epidemiologi för medicin, vård och folkhälsa ger dig nödvändiga redskap för att kunna läsa, förstå och kritiskt granska epidemiologiska forskningsresultat. Den är också skriven för dig som planerar att genomföra ett eget projekt eller bedriva epidemiologisk forskning.Framställningen är problemorienterad: viktiga begrepp och grundläggande metoder introduceras i direkt anslutning till epide

Mounting evidence indicates that the presence of cardiovascular disease (CVD) and risk factors elevates the incidence of cognitive impairment (CI) and dementia. CVD and associated decline in cardiovascular function can impair cerebral blood flow (CBF) regulation, leading to the disruption of oxygen and nutrient supply in the brain where limited intracellular energy storage capacity critically depe

Astrocytes support normal brain function, but may also contribute to neurodegeneration when they become reactive under pathological conditions such as stroke. However, the molecular underpinnings of this context‐dependent interplay between beneficial and detrimental properties in reactive astrogliosis have remained incompletely understood. Therefore, using the RiboTag technique, we immunopurified

NG2 cells, a fourth glial cell type in the adult mammalian central nervous system, produce oligodendrocytes in the healthy nervous tissue, and display wide differentiation potential under pathological conditions, where they could give rise to reactive astrocytes. The factors that control the differentiation of NG2 cells after focal cerebral ischemia (FCI) are largely unknown. Here, we used transge

Alzheimer’s disease (AD) is one of the most serious human, medical, and socioeconomic burdens. Here we tested the hypothesis that a rat model of AD (Samaritan; Taconic Pharmaceuticals, USA) based on the application of amyloid beta42 (Abeta42) and the pro-oxidative substances ferrous sulfate heptahydrate and L-buthionine-(S, R)-sulfoximine, will exhibit cognitive deficits and disruption of the glut
