The composition of a peatland plant community has considerable effect on a range of ecosystem functions. Peatland plant community structure is predicted to change under future climate change, making the quantification of the direction and magnitude of this change a research priority. We subjected intact, replicated vegetated poor fen peat monoliths to elevated temperatures, increased atmospheri...

The aim of the present study was to describe a large cohort of fenfluramine-associated pulmonary arterial hypertension (fen-PAH) and its possible prognostic markers. The records of all patients with a diagnosis of fen-PAH evaluated at the present authors' centre from 1986-2004 were retrospectively studied. Baseline clinical and haemodynamic data were collected, as well as survival times. The me...

The vast occurrence of mine drainage worldwide, documented in descriptive studies, presents a staggering challenge for remediation. Any tool that can move beyond descriptive study and helps to evaluate options for remediation in a way that maximizes improvements to the water quality of streams and minimizes cost of remediation could save valuable resources and time. A reactive solute transport ...

Grasslands established on drained peat soils are regarded as negligible methane (CH4 ) sources; however, they can still exhibit considerable soil CH4 dynamics. We investigated archaeal community composition in two different fen peat soils and one bog peat soil under permanent grassland in Denmark. We used terminal restriction fragment length polymorphism (T-RFLP) fingerprinting and clone librar...

We carried out two studies to test the hypothesis that altered central serotonergic function, as assessed by lower prolactin (PRL) response to fenfluramine (D-FEN), is more closely associated with suicidal behavior than a particular psychiatric diagnosis. A D-FEN test was performed in 85 major depressed inpatients, 33 schizophrenic inpatients, and 18 healthy controls. We showed that PRL respons...

We describe five demonstration programs for displaying variants of effects reported in the vision literature. The demonstrations use a windowed workstation environment, the X Window System Version 11. The performance of the window system is analyzed in terms of our implementation experience and suggestions are made for future window system architectures based on that experience. The visual effe...

Covid-19 salgını, uzaktan eğitimi zorunlu hale getirmiştir. Bu eğitim yaklaşımında; bilgisayar, tablet, akıllı telefon ve televizyon gibi teknolojik ürünler oldukça fazla kullanılmaktadır. teknolojilerin yanında son dönemlerde öğrenme ortamlarında; simülasyonlar, animasyonlar, hologram, artırılmış sanal gerçeklik öğretim teknolojilerinin kullanıldığı görülmektedir. teknolojilerden özellikle hol...

Removal of flap DNA intermediates in DNA replication and repair by flap endonuclease-1 (FEN-1) is essential for mammalian genome integrity. Divalent metal ions, Mg(2+) or Mn(2+), are required for the active center of FEN-1 nucleases. However, it remains unclear as to how Mg(2+) stimulates enzymatic activity. In the present study, we systemically characterize the interaction between Mg(2+) and m...
