Lead has traditionally been added to brass alloys to achieve high machinability, but the exact mechanisms at work are still debated. Lead-free brass alternatives could be developed if these mechanisms were better understood. Accordingly, machinability characteristics were investigated for two brass alloys with similar mechanical properties and phase composition, but with very different machining c
There are many ways to acquire and process diffusion MRI (dMRI) data for group studies, but it is unknown which maximizes the sensitivity to white matter (WM) pathology. Inspired by this question, we analyzed data acquired for diffusion tensor imaging (DTI) and diffusion kurtosis imaging (DKI) at 3T (3T-DTI and 3T-DKI) and DTI at 7T in patients with systemic lupus erythematosus (SLE) and healthy c
This paper explores the idea of the entrepreneurial university and how it differs in diverse regional and institutional settings. From the analysis of university engagement in a regional economic development programme in fifteen city-regions in England (UK), this study identifies three roles that entrepreneurial universities play in regional economic development as growth supporter, steerer, and d
Lebanon, a multi-confessional country with an established consociational democracy, is facing the threat of slipping into state failure as it grapples with its soaring political and economic crisis. The country’s governing system has come under increased and perhaps unprecedented scrutiny since the outbreak of popular protests in 2019 as many accuse an oligarchic political and sectarian elite of s
In recent decades, tech-companies such as Amazon, Google, Facebook, and Apple have grown exponentially, and it can be tempting for cities to try to attract these powerful corporations. This paper explores a particular aspect of this development, namely, how cities brand themselves to win the favor of a single big business. We draw on institutional isomorphism and a case study of North American cit
The share of couples where the wife out-earns the husband is increasing in manycountries. In this paper, I investigate how this income dynamic affects mental health.Using data on all Swedish couples who married in 2001, I show that mental health ispositively associated with own and spousal income. However, it is negatively linked tothe wife’s relative income. Crossing the threshold where the wife
We consider the Gibbs measure on the configurations of N particles on R+ with one fixed particle at one end at 0. The potential includes pair-wise Coulomb interactions between any particle and its 2K neighbors. Only when K = 1, the model is within the rank-one operators, and it was treated previously. Here, for the case K ≥ 2, exponentially fast convergence of density distribution for the spacings
Background: While the efficacy and safety of the contraceptive copper intrauterine device (IUD) have been affirmed, alongside its importance for the prevention of unintended pregnancies, some studies have pointed to negative attitudes toward the device. In recent years, social media communication about it has included claims about systemic side effects, unsubstantiated by medical authorities. Rese
Objective: Arterial stiffness is independently associated with orthostatic hypotension (OH) in older individuals. The relationship between orthostatic blood pressure (BP) and arterial stiffness has not been thoroughly examined in the younger population. To investigate the relationship between orthostatic BP adaptations, central aortic hemodynamics, and arterial stiffness in the general population
This chapter explores the desk as a material object as well as its sym- bolic representations in social work from a professional perspective. As we will demonstrate, different and sometimes incompatible meanings and functions associated with the desk reflect current tensions and profession- al dilemmas: On the one hand, ever since the emergence of the social work profession, the desk has symbolize
Risk management has reduced vulnerability to floods and droughts globally1,2, yet their impacts are still increasing3. An improved understanding of the causes of changing impacts is therefore needed, but has been hampered by a lack of empirical data4,5. On the basis of a global dataset of 45 pairs of events that occurred within the same area, we show that risk management generally reduces the impa
The understanding of patients under the age of 60 with hip fractures have been influenced by preconceptions that fractures are due to high-energy trauma and the risk of osteoporosis is low. The patients’ perspectives have seldomly been presented and the surgical results were insufficiently described. This thesis project was developed in response to the relative lack of research on this patient gro
BACKGROUND: Two studies that examined the interaction between HLA-DRB1 and smoking in Parkinson's disease (PD) yielded findings in opposite directions.OBJECTIVE: To perform a large-scale independent replication of the HLA-DRB1 × smoking interaction.METHODS: We genotyped 182 single nucleotide polymorphism (SNPs) associated with smoking initiation in 12 424 cases and 9480 controls to perform a Mende
We used isozyme markers to obtain an estimate of multiple paternity (mating of females with multiple males) in the unisexual, haploid leafy liverwort Porella platyphylloidea. From a sample of 119 plants, 15 (12.6%) were non-sex-expressing, 16 (13.4%) were females without sporophytes, 38 (31.9%) were males, and 50 (42.0%) were females bearing sporophytes. Thus, 87.4% of all plants expressed sex, an
It is well-documented that there is an intergenerational transmission of divorce from parents to their children. This paper investigates how this transmission is affected by grandparents’ divorce. Using individual-level longitudinal data on marriages and divorces in Sweden, 1905–2015, I show grandparents’ divorce matters for their grandchildren’s divorce risks, even when parents remain married.
