The circular economy is becoming a globalised phenomenon, but the regional emergence of circular business models differs significantly. By adopting a circular business institutionalisation perspective which bridges theory on institutional work and “ecologies of business models” we study the emergence of circular business models in Japan, a region with recent circular policy and business commitment

In 1735, professor Kilian Stobaeus donated his collections to Lund University laying the foundation for the university’s first museum. The ”Museum Stobaeanum” contained over 3000 natural history, historical and ethnographic objects typical of the cabinets of curiosity. This richly illustrated book is the first comprehensive history of these collections.Eighteen chapters, written by an interdiscip

Lymphocytes from human peripheral blood have been separated by countercurrent distribution in a charged aqueous two-phase system composed of Dextran T 500 and polyethylene glycol 6000 with a cell yield of 59–88% and viability above 90%. A highly reproducible partition pattern was seen with four distinct peaks. Lymphocytes with surface membrane immunoglobulin (SmIg) were located in the first part o

Osteoblasts, osteocytes, and osteoclasts (OCs) are involved in the bone production and resorption, which are crucial in bone homeostasis. OC hyperactivation plays a role in the exaggerated bone resorption of diseases such as osteoporosis, rheumatoid arthritis, and osteolytic tumor metastases. This work stems from the finding that OCs can express B7h (ICOS-Ligand), which is the ligand of the ICOS T

Background: Preterm birth and fetal growth restriction (FGR) are associated with structural and functional kidney changes, increasing long-term risk for chronic kidney disease and hypertension. However, recent studies in preterm children are conflicting, indicating structural changes but normal kidney function. This study therefore assessed kidney structure and function in a cohort of adolescents

Metalloenzymes are proteins that contain one or more metal ions bound to protein. They constitute about one-third of all enzymes known so far and they often perform hard chemical reactions involving small substrates, like H2 and N2. In our research, we focus on those metal ions that are located in the active sites and perform redox reactions, i.e. involving electron transfer. Why enzymes?Metalloenzymes catalyse a wide variety of reactions in nature. In the thesis, I have studied the reaction mechanism of three metalloenzymes, viz. [NiFe] hydrogenase (H2ase), dimethyl sulfoxide reductase (DMSOR) and formate dehydrogenase (FDH), by theoretical methods, namely quantum mechanics (QM), combined quantum mechanical and molecular mechanics (QM/MM), as well as QM/MM thermodynamic cycle per

Title: Perceiving the Mundane Necessity - How Consumers Perceive Pharmacies in an Increasingly Competitive Swedish Market Course: BUSN39 - Degree Project in Global Marketing Authors: David Ingvarsson & Oscar Egard Supervisor: Tommy Shih Purpose: The purpose of our study is to identify and gain an understanding of how consumers perceive pharmacies on the Swedish pharmaceutical market.

De vanligaste kontakterna under vikingatiden ur ett svenskt perspektiv gick österut. Miljontals islamiska mynt flödade in i Skandinavien från Nordafrika, kalifatet och det samanidiska herraväldet i Centralasien. Deras ursprung varierade, och silverströmmens kronologi gör det möjligt att beskriva föränderliga relationer mellan aktörerna. Några välkända artefakter från samma riktning kom till Skandi

Many contemporary work organizations are concerned with how they can influence employees’ intrinsic motivation. Their quest follows a widespread realization that people do not necessarily work harder because of monetary incentives or direct commands. Instead, people’s inner motives, their urge to self-realize and get recognition, are seen as key factors influencing workers’ mindsets and behaviors.

Fluxes of methane, CH4, were measured with the eddy covariance (EC) method at a small boreal lake in Sweden. The mean CH4 flux during the growing season of 2013 was 20.1 nmol m−2 s−1 and the median flux was 16 nmol m−2 s−1 (corresponding to 1.7 mmol m−2 d−1 and 1.4 mmol m−2 d−1). Monthly mean values of CH4 flux measured with the EC method were compared with fluxes measured with floating chambers (

Protein homeostasis in cells, proteostasis, is maintained through several integrated processes and pathways and its dysregulation may mediate pathology in many diseases including Duchenne muscular dystrophy (DMD). Oxidative stress, heat shock proteins, endoplasmic reticulum (ER) stress and its response, i.e. unfolded protein response (UPR), play key roles in proteostasis but their involvement in t

The free energy of interaction between two nanometric clay platelets immersed in an electrolyte solution has been calculated using Monte Carlo simulations as well as direct integration of the configurational integral. Each platelet has been modeled as a collection of charged spheres carrying a unit charge-the face of a platelet contains negative charges, and the edge, positive charges. The calcula

In this project, nanoimprint lithography has been applied to define gold particles on the surface of an InP wafer. For achieving this aim, a dry etching process has been developed to create resist undercut for the lift-off. In order to prepare the required undercuts, RIE parameters were optimized and desired undercuts were made at etch times of 80 s to 120 s. Also, to obtain anisotropy and high et

Background: The demographic shift is fast becoming a global challenge. Populations ageing rapidly is widely seen as one of the most powerful transformative forces affecting society over the next four decades.Due to the demographic challenge in most countries it is important to consider making working life sustainable. It is obvious that the main factor that distinguishes senior workers from other
