Europe is struggling to reduce its CO2 emissions and to fulfil commitments made according to Kyoto protocol. At the same time, Europe does not possess enough fossil energy resources to cover its needs and thus consumption of imported fossil fuels is growing, placing threats upon economic stability. In order to combat these challenges, renewable energy sources and biomass in particular are expected
The introduction of new farming technologies, such as high-yielding varieties, has for long been regarded as one of the best strategies to increase agricultural production, and to combat poverty and food-insecurity. Since around 2005, New Rice for Africa (Nerica) is one of the main development strategies for combating such issues in Sierra Leone, and in many other African countries. Africa Rice Ce
Chronic obstructive pulmonary disease (COPD) is a progressive condition characterized by airway remodeling, including emphysema and fibrosis. Proteoglycans and their glycosaminoglycan (GAG) chains are key components of the extracellular matrix and may be altered as the disease advances. This study analyzed lung tissue from COPD patients (GOLD stages II-III and IV), non-COPD smokers, and non-smoker
This special issue addresses questions of how the practices of (welfare) state practitioners and policy makers (trans)form the lives of families. The aim is to illuminate how social policies and educational institutions influence parents’ hope for the wellbeing and future success of their children through new forms of audit culture and policies of early interventions. We i
Quantum information and quantum computing are based on the concept and manipulation of qubits. In this pedagogical Tutorial-written with the aim of assisting self-motivated undergraduate mathematics, physics, and engineering students-transformation of these qubits, especially the Hadamard transformation (H) and the phase shifter transformation (φ), is illustrated. Two-qubit gates and their applica
Renewable hydrogen can be transported using different hydrogen carriers and modes of transport. Each carrier and mode is associated with different drawbacks and benefits relating to – among other factors – storage density and losses. The forthcoming expansion of offshore wind is likely to be coupled with hydrogen production in some way and there are many different ways that this can be done. Th
Epidemiological studies have shown a high prevalence of mental illness among the elderly. Clinical data however indicate both insufficient detection and treatment of illnesses. Suggested barriers to treatment include conceptions that mental health symptoms belong to normal aging and lack of competence among staff in elderly care in detecting mental illness. A Mental Health First Aid (MHFA) trainin
Public transport plays a major role in sustainable development of urban areas. However, transportation and infrastructure have to be efficient and in line with the wishes and demand of passengers. Local people have knowledge and experiences of the quality of services they want. When locals are involved, they include grass-root knowledge about ecology, environment, local livelihood problems and res
BACKGROUND: Female gender is a risk factor for sustaining anterior cruciate ligament (ACL) injury. However, little is known about possible sex differences in patients with ACL injury/reconstruction. PURPOSE: To study sex differences in patient-reported outcomes before and at 1 and 2 years after ACL reconstruction and to present reference values. STUDY DESIGN: Cohort study; Level of evidence, 2. ME
Many microfluidic devices have been developed to separate rare cells, e.g. circulating tumor cells. The collection and analysis of the separated rare cells pose a challenge as it may lead to loss of target cells since extremely small number of cells are usually suspended in a large volume after separation. Here, we present an integrated device that allows acoustophoretic target cell separation and
Context: De novo brain tumors developing after treatment of pituitary/sellar lesions have been reported, but it is unknown whether this is linked to any of the treatment modalities. Objective: To study the occurrence of malignant brain tumors and meningiomas in a large cohort of patients treated for pituitary/sellar lesions, with special emphasis on the role of radiotherapy (RT). Patients and Meth
Narrative is one method of tapping individual and collective memory where human experience is organized into temporally meaningful episodes and where a "point" is often made. In research projects that I have carried out about working life, "body stories" are often spontaneously related in making a "point." These stories exemplify "doing gender"-that is how gendered relations (that revolve around e
Designing a spare part distribution network that fits the company’s strategy and customer requirement is a common problem for many organizations. Due to the advantages and disadvantages of different distribution network designs, it can be difficult to capture all requirements and contextual factors when designing the network. Furthermore, customer requirements and company strategy can change over
In object-oriented programs, the relationship of an object to many objects is usually implemented using indirection through a collection. This is in contrast to a relationship to one object, which is usually implemented directly. However, using collections for relationships to many objects does not only mean that accessing the related objects always requires accessing the collection first, it also
Den additiva tillverkningsprocessen och kvalificeringen av komponenter i metall är komplex och tillverkningsmetoden är inte ännu fullständigt förstådd. Syftet med detta examensarbete är därför att förvärva kunskap om kvalificeringsprocesser kopplade till additiv tillverkning i metall och att utveckla en hållbar kvalificering för additivt tillverkade komponenter hos Alfa Laval. KvalificeringsprocedThe process of additive manufacturing and qualification of components in metal is complex, and the manufacturing method is still not fully understood. Therefore, the purpose of this thesis is to gather knowledge of the qualification procedures connected to additive manufacturing in metal and to develop sustainable qualification for additively manufactured parts at Alfa Laval. The qualification pro
