Agriculture is interrelated with the socio-economic and natural environment and faces increasingly the problem of managing its multiple functions in a sustainable way. Growing emphasis is on adequate policies that can support both agriculture and sustainable development. Integrated Assessment and Modelling (IAM) can provide insight into the potential impacts of policy changes. An increasing number
PURPOSE: EUROCARE collected data from population-based cancer registries in 20 European countries. We used this data to compare childhood cancer survival time trends in Europe. PATIENTS AND METHODS: Survival in 44,129 children diagnosed under the age of 15 years during 1983 to 1994 was analyzed. Sex- and age-adjusted 5-year survival trends for 10 common cancers and for all cancers combined were es
The signal obtained with q-space NMR imaging applied to a confined liquid is directly related to the pore shape in the limit where all molecules have sampled the whole pore. We investigate the diffusion of water across a similar to50 mum thick film formed between planes of glass. The diffusion time t is changed almost three orders of magnitude. For short t, the root-mean-square displacement increa
Improving the product lifetime of consumer electronics can provide significant environmental benefits. However, there is a tendency among both professional users and consumers to change products, like computers and mobile phones regularly, and as a result their lifetimes become increasingly shorter. With the rise of the Circular Economy, new policies to promote longer product lifetimes have emerge
In the present paper, the heat transfer of gravity-driven dense particle flow around five different shapes of tubes is numerically studied using discrete element method (DEM). The velocity vector, particle contact number, particle contact time and heat transfer coefficient of particle flow at different particle zones around the tube are carefully analyzed. The results show that the effect of tube
Mainstream option valuation theory relies implicitly on the assumption that latent states (such as stochastic volatility) and parameters are perfectly known, an assumption that is dubious in many ways. Computing the value of options under the assumption of perfect knowledge will typically introduce bias. Correcting for the bias is straightforward but can be computationally expensive. Fourier-base
The work in this thesis was carried out to highlight important chemical pathways in skeletal mechanisms for the three smallest alcohol fuels (methanol, ethanol and npropanol), two representative fuel alkanes n-heptane and n-decane, and finally the biodiesel surrogates, methyl-decanoate, methyl-5-decenoate, and methyl-9-decenoate. This aim was set up to further the efforts of creating Computational
Several diverse types of UH3-based hydrides can be prepared by hydrogenation of bcc U-based alloys. Pair Distribution Function (PDF) analysis using high-energy X-rays identified that the (UH3)1-xMo x hydrides are nanocrystalline, with the structure motif based mainly on the β-UH3 structure. α-UH3 represents a minority component. On the other hand, PDF of the (UH3)1-xZr x hydrides corresponds well
A new model of color reconnection in the Monte Carlo generator Herwig 7 is presented. It is based on the minimization of a boost-invariant distance of the parton system, where all partons have momentum as well as spacetime position assigned. We test the influence of both types of variables, namely the rapidity span and transverse distance, on the actual need to reconnect the system to better descr
The root-associated habit has evolved on numerous occasions in different fungal lineages, suggesting a strong evolutionary pressure for saprotrophic fungi to switch to symbiotic associations with plants. Species within the ubiquitous, saprotrophic genus Mycena are frequently major components in molecular studies of root-associated fungal communities, suggesting that an evaluation of their trophic
The damping ratio is a key performance measure in systems that can be modelled as networks of masses and springs. We derive a lower bound on this quantity that applies to such networks when the masses are subject to viscous damping. The result allows the size of the damping ratio to be understood as a function of the system parameters. We use this to derive a decentralised criterion which, if sati
In this paper, we determined the optimal flow rate trajectory during the loading phase of a mAb capture column. For this purpose, a multi-objective function was used, consisting of productivity and resin utilization. Several general types of trajectories were considered, and the optimal Pareto points were obtained for all of them. In particular, the presented trajectories include a constant-flow l
Resistance to antibiotics is a major threat to the effectiveness of modern health care. This study examines if pay-for-performance (P4P) to care providers stimulates the appropriate use of antibiotics; in particular, if P4P can induce a substitution away from broad-spectrum antibiotics, which contribute more to the development of resistance, to less resistance-driving types. In the context of Swed
Although there has been a long tradition of public space-related land speculation and development, the recent success of the High Line in New York has highlighted the transformative effect carefully designed and curated public spaces can have on the local economy. By prioritising exchange value over use value, governments and developers are exploiting the production of public spaces as a means for
In the wake of global crises concerning, for example, inequalities, migration, pandemics, and the environment, ethical concerns have come to the fore. In this thematic issue, we are especially interested in the role that the planning, design, and materialities of the built environment can take in relation to ethics, and we present four different openings or themes into urban ethics that we also th
One of the defining features of animals is their ability to navigate their environment. Using behavioral experiments this topic has been under intense investigation for nearly a century. In insects, this work has largely focused on the remarkable homing abilities of ants and bees. More recently, the neural basis of navigation shifted into the focus of attention. Starting with revealing the neurons
Popular Abstract in Swedish Frågan om marknadshandelns karaktär har aktualiserats genom de skandaler inom företagsvärlden som media har lyft fram under senare år. Dagens situation väcker frågor om den handel som förekom i äldre samhällen? Existerade marknadshandel till exempel under vikingatid? Om så var fallet hur uppfattades och hanterades marknadshandel i detta samhälle? Handelns roll för det The view of the exchange and trade that took place during the Viking Age has varied considerably. This variation is obvious from a scrutiny of how one and the same place, Birka, is described by different scholars over a period of a hundred years. Two very polarized pictures of Birka appear: A town with a mostly free market-oriented trade or an emporium with an administered commodity exchange contr
Background: Families living with mental illness can experience added burden and eventually own ill health. National and international guidelines support the development of web based solutions to cost-effectively address health care needs. Mapping patterns of internet use may help tailor interventions to effectively address users' needs. Aim: The study's aim was to explore the contents of relatives
