Biodegradation rate is an important index to evaluate the environmental risk of chemicals, which is usually determined by measuring oxygen consumption through respirometer in a biodegradation test. However, atmospheric pressure variations affect reactor oxygen concentration and oxygen volume recorded by respirometer in biodegradation test, and the parameters of reactor volume and test material amo
Herein we report an efficient hydrosilylation strategy to selectively defunctionalize biomass-derived levulinic acid into value-added chemicals such as pentane-1,4-diol, pentan-2-ol, 2-MTHF and C5 hydrocarbons by using cost-effective silanes and the commercially available catalyst B(C6F5)3 at room temperature. All reactions work well in chlorinated solvents but, as a greener alternative, most reac
The Sixth Assessment Report (AR6) of the Intergovernmental Panel on Climate Change represents the state of knowledge of anthropogenic disruption to the climate system, its diverse ecosystem and societal impacts, and the imperative for and challenges of mitigation and adaptation responses. It is foundational for global climate policymaking. This paper examines the place of tourism in AR6 and review
Pulmonary arterial hypertension (PAH) is a progressive disease with no cure. Healthcare resource utilization (HCRU; hospitalization, outpatient visits, and drug utilization) before diagnosis and productivity loss (sick leave and disability pension) before and after PAH diagnosis are not well known. By linking several Swedish national databases, this study have estimated the societal costs in a nat
Human fetal hemoglobin (HbF) is an attractive starting protein for developing an effective agent for oxygen therapeutics applications. This requires that HbF can be produced in heterologous systems at high levels and in a homogeneous form. The introduction of negative charges on the surface of the α-chain in HbF can enhance the recombinant production yield of a functional protein in Escherichia co
A long-standing question is what invariant subsets can be shared by two maps acting on the same space. A similar question stands for invariant measures. A particular interesting case are expanding Markov maps of the circle. If the two involved maps are commuting the answer is almost complete. However very little is known in the non-commutative case. A first step is to analyse the structure of the
Aim: Our aim was to investigate in a large population-based cohort study whether increased arterial stiffness and subclinical atherosclerosis in the coronary arteries differ at different stages of dysglycaemia. Methods: Data were obtained from SCAPIS, a population-based cohort of participants 50–64 years. The study population of 9379 participants was categorised according to glycaemic status: norm
Background: The SYNAPSE study (NCT03085797) demonstrated that mepolizumab decreased nasal polyp (NP) size and nasal obstruction in patients with chronic rhinosinusitis with NP (CRSwNP). Methods: SYNAPSE, a randomized, double-blind study, included patients with recurrent, refractory, severe CRSwNP, eligible for repeated surgery despite receiving standard of care (SoC). Patients received 4-weekly me
Metal-semiconductor nanoparticle heterostructures are exciting materials for photocatalytic applications. Phase and facet engineering are critical for designing highly efficient catalysts. Therefore, understanding processes occurring during the nanostructure synthesis is crucial to gain control over properties such as the surface and interface facets’ orientations, morphology, and crystal structur
This study examines how multiple blockholder structures affect family firm performance. Building on arguments from both principal–principal agency and familiness perspectives, we suggest that asymmetrical distribution of voting power among family and nonfamily blockholders hurts firm performance. Further, we suggest that the larger the number of blockholder types, the stronger the negative effect
The connection between neuroscience, popular media and lay perceptions of the brain involves the framing of complex scientific processes and results through familiar cultural narratives and metaphors. Such narratives are often built on the premise that neuroscience, with the help of powerful new technologies, will finally solve the mysteries of brain and mind, consciousness and morality. At the sa
Driven by the increasing demands on data rate from applications, the wireless communication standard has for decades been evolving approximately at a pace of one generation per ten years. Following this trend, the ambitious plan to replace the current cellular mobile network standard (4G) with the next generation standard (5G) is going through the standardization phase and is getting close to its
The emulsion stabilization functionality of surfactants and biopolymers can be replaced by solid particles adsorbed at the interface, where they create a category of emulsions known as Pickering emulsions. Recently, health and environmental concerns have led to new market demand for natural, biodegradable and renewable sources of ingredients. Starch granules meet these ingredient requirements and
Eye movements during regular reading, thorough reading, skimming, and spell checking of single pages of text were measured, to investigate how high-level reading tasks elicited by instructions affect reading behavior. Word frequency and word length effects were found. All results were compared to regular reading. Thorough reading involved longer total reading times and more rereading, and resulted
Even though architecture often might be conceived of as timeless, there has always been different ways of dealing with time in architectural discourse and practice. Since the early 20th century the temporal activities that goes on in and between buildings has, for example, been addressed by concepts such as function, flexibility and program. Architecture is of inevitable importance in our everyday
The quantification and characterization of circulating immune cells provide key indicators of human health and disease. To identify the relative effects of environmental and genetic factors on variation in the parameters of innate and adaptive immune cells in homeostatic conditions, we combined standardized flow cytometry of blood leukocytes and genome-wide DNA genotyping of 1,000 healthy, unrelat
In the last few years many detector technologies for thermal neutron detection have been developed in order to face the shortage of 3He, which is now much less available and more expensive. Moreover the 3He-based detectors can not fulfil the requirements in performance, e.g. the spatial resolution and the counting rate capability needed for the new instruments. The Boron-10-based gaseous detectors
This paper investigates the usability of a cost model to assess sustainable production. The aim is to develop an established cost model to also take sustainability into consideration and hence evaluate sustainable production on the shop floor. To facilitate the analyse literature have been studied to find indicators for sustainable production. The indicators have then been mapped together with parThis paper investigates the usability of a cost model to assess sustainable production.
