Structural and compositional changes during UHT fouling removal—Possible mechanisms of the cleaning process

Ultra-high temperature (UHT) treatment of milk forms a deposit or fouling in the processing equipment that is mineral-based with an enclosed protein network. This study addresses the fundamental mechanisms that control the removal of this deposit. For this purpose, the structural and compositional changes during the cleaning process have been studied. The structure analysis was performed with scan

Kinetics of carbon and nitrogen assimilation by heterotrophic microorganisms during wastewater treatment

The present study highlights microbial assimilation of carbon (glucose) and nitrogen (NH3–N) from wastewater using heterotrophic bioconversion process. Experiments were conducted to study the role of heterotrophic microbes towards removal of carbon and nitrogen at varying initial concentrations of carbon (COD, 533 to 1600 mg/l) and nitrogen (NH3–N, 73 to 249 mg/l) keeping the initial biomass of mi

Hybridization, sex-specific genomic architecture and local adaptation

While gene flow can reduce the potential for local adaptation, hybridization may conversely provide genetic variation that increases the potential for local adaptation. Hybridization may also affect adaptation through altering sexual dimorphism and sexual conflict, but this remains largely unstudied. Here, we discuss how hybridization may affect sexual dimorphism and conflict due to differential e

Issues on transparency, accountability and control in hybrid organisations : The case of enterprises owned by local government

Our purpose is to critically discuss the quality of governability and scrutiny of, as well as insight in, enterprises owned by local government. Our analysis is empirically grounded in an in-depth case study of one of Sweden’s 10 largest municipalities. The ambition is to highlight troublesome areas and danger zones when it comes to public owning of corporations. We have consulted diverse types of

Botulinum and tetanus neurotoxins

Botulinum neurotoxins (BoNTs) and tetanus neurotoxin (TeNT) are the most potent toxins known and cause botulism and tetanus, respectively. BoNTs are also widely utilized as therapeutic toxins. They contain three functional domains responsible for receptor-binding, membrane translocation, and proteolytic cleavage of host proteins required for synaptic vesicle exocytosis. These toxins also have dist

Oxidative Cleavage of Cellobiose by Lytic Polysaccharide Monooxygenase (LPMO)-Inspired Copper Complexes

The potentially tridentate ligand bis[(1-methyl-2-benzimidazolyl)ethyl]amine (2BB) was employed to prepare copper complexes [(2BB)CuI]OTf and [(2BB)CuII(H2O)2](OTf)2 as bioinspired models of lytic polysaccharide copper-dependent monooxygenase (LPMO) enzymes. Solid-state characterization of [(2BB)CuI]OTf revealed a Cu(I) center with a T-shaped coordination environment and metric parameters in the r

Femtosecond x-ray diffraction reveals a liquid–liquid phase transition in phase-change materials

In phase-change memory devices, a material is cycled between glassy and crystalline states. The highly temperature-dependent kinetics of its crystallization process enables application in memory technology, but the transition has not been resolved on an atomic scale. Using femtosecond x-ray diffraction and ab initio computer simulations, we determined the time-dependent pair-correlation function o

Public procurement of reconditioned furniture and the potential transition to product service systems solutions

The transition to a circular economy requires the development of new business models. However, ‘circular’ businesses face a number of barriers when competing in the current ‘linear’ economy, and may require the support of public policies. Public procurement may be applied for this purpose, as it can support emerging markets for reconditioned and remanufactured products. Public procurement can also

Method for producing cyclic carbonates

Linear or cyclic carbonates as potential monomers for isocyanate-free polyurethanes and polycarbonates were prepared from polyols and dialkylcarbonatesor diphenyl carbonates. This invention was developed to produce linear or cyclic carbonates with or without using catalysts. Polyol compounds were reacted with carbonates such as dimethylcarbonate and diethylcarbonate to produce thecorresponding lin

”Så har Malmö lyckats få ner våldsbrottsligheten”

Under de senaste tre åren har Malmö haft 26 dödsskjutningar. Men efter att polisen börjat sätta hårt mot hårt med ett effektivt spanings­arbete, punktmarkering av tongivande kriminella, samverkan med andra myndigheter och en satsning på avhopparverksamheten har våldet med skjutvapen minskat betydligt, skriver kriminolog Ardavan Khoshnood.Over the past three years, Malmö has witnessed 26 homicides by firearm. Only after that the police responded with vigorous countermeasures like a more effective surveillance, marking high offending and leading criminals, collaboration with other authorities and a massive investment in the defector's program. Ardavan Khoshnood, Criminologist, writes that these measurements have contributed to a sig

Family caregivers and decision-making for older people with dementia

This article addresses the dilemmas concerning legislation, individual autonomy and the reality of everyday life for people coping with dementia. We describe and analyse decision-making in relation to older people with dementia in Sweden, within the area of social work regulated by the Social Services Act and the Parental Act. Swedish legislation is based on the individual’s autonomy and capacity

The effect of two types of maximal voluntary contraction and two electrode positions in field recordings of forearm extensor muscle activity during hotel room cleaning

Purpose. This study aimed to investigate the effects of using hand grip or resisted wrist extension as the reference contraction, and two electrode positions, on field recordings of forearm extensor muscle activity. Materials and methods. Right forearm extensor muscle activity was recorded using two electrode pairs (over the most prominent part (position 2) and proximal to that (position 1)) durin

An upbringing with substance-abusing parents : Experiences of parentification and dysfunctional communication

Aim: To increase understanding of the consequences of growing up with substance-abusing parents, including how this can influence the experience of becoming a parent. Methods: In-depth interviews were conducted with 19 parents who had participated in an Infant and Toddler Psychiatry Unit intervention programme and who had experienced substance-abusing parents in their family of origin. Directed qu
