[NiFe] hydrogenases catalyse the reaction H2 <-> 2H(+) + 2e(-). Several states of the enzyme have been observed by spectroscopic methods. Among these, the two most oxidized states, called the unready Ni-A and Ni-SU states, have been especially intriguing, because they take a much longer time to activate than the corresponding ready Ni-B and Ni-SI states. It has recently been suggested that the unr
The design of port complexes is a process that requires considering geographical and economic features of the territory. It is necessary to aggregate the characteristics of coastal landscapes, seascapes, artificial elements, dangerous objects, etc. The experience of implementing such projects (for example, in Sabetta) suggests that all participants in the design process need highly precise geograp
Introduction: Due to the high cost and complexity, the oral glucose tolerance test is not adopted as the screening method for identifying diabetes patients, which leads to the misdiagnosis of patients with isolated post-challenge hyperglycemia (IPH), that is., patients with normal fasting plasma glucose (<7.0 mmoL/L) and abnormal 2-h postprandial blood glucose (≥11.1 mmoL/L). We aimed to develop a
Background Providing high quality nursing care for patients with malignancies is complex and driven by many factors. Many of the associations between nursing care quality, trust, health status and individualized care remain obscure. Objective To empirically test a model of association linking hospitalized cancer patients’ health status, nursing care quality, perceived individuality in care and tru
Gross primary production (GPP) of the vegetation is the largest carbon exchange process of the global carbon cycle. Currently, within satellite-based remote sensing, GPP is generally modelled using linear light use efficiency models where GPP is related to photosynthetically active radiation absorbed by the green vegetation (APAR). These models work well on moderate to low spatiotemporal averaging
Background: A wrist-worn wearable device for acquiring limb and chest ECG leads (wECG) may constitute a promising approach to detection of acute myocardial infarction (AMI). However, it remains to be demonstrated whether the information conveyed by the wECG is sufficient for AMI detection. Objective: To explore explainable machine learning models for detecting AMI using the wECG. Methods: Two type
This report examines the possibilities of decarbonising operation & maintenance vessels for a prospective floating offshore wind power park at the Utsira Nord site in Norway, through self-sufficient energy carrier production utilizing power-to-X-solutions. Possible alternative fuels are identified as compressed hydrogen, batteries, liquid hydrogen, ammonia, methanol, and biofuels, out of which
Global warming and climate change is getting a serious issue and a great environmental threat that affects many aspects of life and our ways of living on this planet. The negative effects of climate change are endangering our communities, health and economy. Global warming can be considered as a main reason for sea rising levels, extreme heat which is responsible for many forests’ fires, severe dr
Selective catalytic oxidation (SCO) of ammonia is a interesting field of research and is becoming increasingly more popular due to ammonias role as a hydrogen carrier for ammonia based hydrogen production. With the rise of ammonia based hydrogen, focus now lies on finding cheap and efficient ways to remove unreacted ammonia from the final gas stream. This to be done, without burning or destroying
On this page you can read about the Faculty’s quality assurance work and about European, national and internal regulations, policies and recommendations that regulate higher education institutions and that are the starting point for the Faculty’s quality assurance processes in third cycle (doctoral level) education.The Faculty of Medicine is working systematically to maintain and develop quality i
- when does what happen? The purpose of your time here at the Pufendorf IAS is to give you the space to explore the research problems which you described in your Theme or ASG application. As you know, we don’t expect deliverables, specific research output, but we do ask that you keep certain things in mind at specific times during your Pufendorf-year. AugustTheme: What day of the week would suit y

Boreal forests and peatlands are globally significant carbon stores but they are threatened by rising air temperatures and changes in precipitation regimes and the frequency of natural disturbances. Predicting how the boreal biome will respond to climate change depends on being able to accurately model and upscale the greenhouse gas fluxes between these ecosystems and the atmosphere. This thesis f
AbstractNitrogenase is the only enzyme that can convert the inert nitrogen molecule to ammonia, so that it can be used for biomass production and in biosynthetic pathways. It contains a complicated acitve site, composed of eight metal ions, nine sulfur ions and one carbide ion (the FeMo cluster). Although it has been thoroughly studied with crystallographic, biochemical, kinetic, spectroscopic and
Introduction Common complications after surgical procedures include surgical site infection, wound rupture and incisional hernia. Wound healing can be influenced by the technique for abdominal access and closure. A Suture-Length to Wound-Length (SL/WLr) ratio ≥ 4 is advised to achieve a high-quality wound closure. This thesis describes the background and clinical realities of abdominal wall relat
Risk and safety assessment for fieldwork and excursions The employer/coordinator of the fieldwork has to make a risk assessment for all fieldwork in accordance with the law of Systematic Work Environment Management (In Swedish “SAM”), and it has to be documented. This document applies mainly to fieldworkers at CEC and to fieldwork within Sweden, and considers the most common risks. Other risks may
Background: Soils contain the largest stock of organic carbon (C) in terrestrial ecosystems and changes in soil C stocks may significantly affect atmospheric CO2. A significant part of soil C is present in cultivated soils that occupy about 35 % of the global land surface. Agricultural intensification has led to practices that may decrease soil organic carbon (SOC), and agricultural management has
