Rotor–stator mixers (RSMs) are widely used for emulsification and mixing. However, relatively little is known about the relationship between RSM design, hydrodynamics and performance. Previous studies have investigated shaft power draw as a function of design. However, power draw alone is not sufficient to predict efficiency. In order to understand the effect on performance it is important to inve

Although Sweden is a northern country with fairly low outdoor temperatures most of the year, its district cooling (DC) systems are expected to expand. Some actors claim that there is potential for at least a doubling of DC in Sweden. One reason for this is that demand for cooling increases with the increased use of electronics such as computers, resulting in higher indoor temperatures from waste h

Sustainable business model innovation is increasingly viewed as a lever for systems change for sustainability across businesses and industries. Banks hold a unique intermediary role in sustainable development, but also have a difficult position after the 2008 financial crisis. This paper aims to explore business models for sustainability in the service industry, particularly banking. It explores t

Objective: This study aims to evaluate the potential association between periodontitis, the number of teeth and cognitive functions in a cohort of older adults in Sweden. Material and methods: In total, 775 individuals from 60 to 99 years of age were selected for the study. A clinical and radiographic examination was performed. The number of teeth and prevalence of periodontal pockets and bone los

The paper addresses a puzzle about the proportionality requirement on self-defense due to L. Alexander. Indirectly the puzzle is also relevant to the proportionality requirement on punishment, insofar as the right to punish is derived from the right to self-defense. Alexander argues that there is no proportionality requirement on either self-defense or punishment, as long as the aggressor/offender

In this study the dosimetric properties of alumina (Al2O3) substrates found in resistors retrieved from mobile phones were investigated. Measurements of the decline of optically stimulated luminescence (OSL) generated following exposure of these substrates to ionising radiation showed that 16% of the signal could still be detected after 2 years (735 days). Further, the magnitude of the regenerativ

We propose a novel approach to estimation, where a set of estimators of a parameter is combined into a weighted average to produce the final estimator. The weights are chosen to be proportional to the likelihood evaluated at the estimators. We investigate the method for a set of estimators obtained by using the maximum likelihood principle applied to each individual observation. The method can be

Incorporation of membrane proteins and internal reporter systems directly into giant vesicles, during their formation from a hydrogel surface, has emerged as a promising new concept in membrane protein characterization. Here, we provide the detailed protocol for a glucose transporter activity assay based on giant vesicles containing a fluorescent enzyme-linked reporter system internally. This assa

In Sweden, energy-consulting services, here referred to as local energy advising (LEA), have traditionally contributed to improving household energy efficiency. The aim of this article is to analyze the development of this service from the 1970s, when the consultancy came into being, to the present day, through a review of documents and published literature. The analysis enables the understanding

Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related fatalities and is characterized by acute respiratory distress following blood transfusion. Donor antibodies are frequently involved; however, the pathogenesis and protective mechanisms in the recipient are poorly understood, and specific therapies are lacking. Using newly developed murine TRALI models based o

I svenska vägtunnlars trafikutrymme ska det finnas utrymningsbelysningsarmaturer i form av vägledande utrymningsljus. För Trafikverkets vägtunnlar styrs utformningen av innehållet i SS-EN 16276:2013 om utrymningsbelysning i vägtunnlar. I denna standard föreskrivs dock endast en minsta ljusstyrka (motsvarande 1 candela i alla riktningar som de kan ses från en utrymmande person), vilket är ett mycke

Background An increased rate of cell death by apoptosis has been implicated in both diabetes and atherosclerosis. Apoptosis can be induced through activation of the death receptors TNF receptor 1 (TNFR-1), TRAIL receptor 2 (TRAILR-2) and Fas. Soluble forms of these receptors are found in plasma. The objective of this study was to determine if soluble death receptors are markers of receptor-activat
