Diverse and complex interactions as well as multi-actor systems characterise resource use and re- source policy. This makes system analysis a relevant tool to orient resource policy towards the long term. Analysing such complex systems requires systemic thinking, consideration of causal loops as well as time-lags and delays in system responses.In the SimRess project, system analysis encompassed pa
Physiological adaptation through acclimation is one way to cope with temperature changes. Biochemical studies on acclimation responses in ectotherms have so far mainly investigated consequences of short-term acclimation at the adult stage and focussed on adaptive responses. Here, we assessed the consequences of rearing Drosophila melanogaster at low (12°C), benign (25°C) and high (31°C) temperatur
It is well known that nonirradiated cells can exhibit radiation damage (bystander effect), and recent findings have shown that nonirradiated cells may help protect irradiated cells (rescue effect). These findings call into question the traditional view of radiation response: cells cannot be envisioned as isolated units. Here, we investigated traditional colony formation assays to determine if they
The "habitat heterogeneity hypothesis" predicts positive effects of structural complexity on species coexistence. Increasing habitat heterogeneity can change the diversity (number of species, abundances) and the functional roles of communities. The latter, however, is not well understood as species and individuals may respond very differently and dynamically to a changing environment. Here, we exp
C.W. Mills suggests that having sociological imagination entails having ability to both distinguish between and connect personal troubles and public issues. This has been a guiding principle for much sociology in the last fifty years, but is never simple and continues to challenge the discipline. Especially the increasing number of sociologists engaging in endeavours to explain, understand, and im
Most of the world's poor live in developing markets and face unmet needs in core areas such as education, health, energy, sanitation and financial services. This offers businesses a vast opportunity for growth as these economies emerge from low-income to middle-income status. Social businesses in particular address a social need while generating profits typically reinvested into the business itsel
We present two new data structures for computing values of an n-variate polynomial P of degree at most d over a finite field of q elements. Assuming that d divides q-1, our first data structure relies on (d+1)n+2 tabulated values of P to produce the value of P at any of the qn points using O(nqd2) arithmetic operations in the finite field. Assuming that s divides d and d/s divides q-1, our second
Objective. To assess lung cancer risk in systemic lupus erythematosus (SLE), relative to demographics, drug exposures, smoking, and disease activity. Methods.We analyzed data from 14 SLE cohorts. We calculated adjusted HR estimates for lung cancer in SLE, relative to demographics, smoking, time-dependent medication exposures, and cumulative disease activity [mean adjusted SLE Disease Activity Inde
Harmonic periods have wide applicability in industrial real-time systems. Rate monotonic (RM) is able to schedule task sets with harmonic periods up to 100% utilization. Also, if there is no release jitter and execution time variation, RM and EDF generate the same schedule for each instance of a task. As a result, all instances of a task are interfered by the same amount of workload. This property
3D-macroporous chitosan-based scaffolds (cryogels) were produced via growth of metal-polymer coordinated complexes and electrostatic interactions between oppositely charged groups of chitosan and metal ions under subzero temperatures. A mechanism of reduction of noble metal complexes inside the cryogel walls by glutaraldehyde is proposed, which produces discrete and dispersed noble metal nanoparti
Thrombospondin 4 (TSP-4) expression is induced in the heart and vasculature under pathological conditions, including myocardial infarction, myocardial pressure overload, and hypertension. TSP-4 is linked to remodelling processes, where it may affect extracellular matrix protein organization. In previous work, we studied the role of TSP-4 in small arteries during hypertension using Ang II-treated T
One of the central issues in ecology is the identification of processes affecting the population structure and dynamics of species with complex life cycles. In such species, variation in both the number of larvae that enter a population and their phenotype are important drivers of survival and growth after metamorphosis. Larval experience can have strong effects on key postmetamorphic traits, but
Transient hepatic arterial occlusion causes necrosis in solid hepatic tumors in the rat, but regrowth of tumor cells and capillaries takes place from the tumor periphery. It was therefore considered of interest to combine this treatment with the angiogenesis inhibitor TNP-470 (therapeutic model). Wistar rats with a dimethylhydrazine-induced adenocarcinoma implanted into the liver received one of t
Idiopathic Addison's disease develops as a consequence of autoimmune destruction of steroid-producing cells in the adrenal gland. A major autoantigen is 21-hydroxylase (21OH; P450c21), which is involved in the biosynthesis of cortisol and aldosterone in the adrenal cortex. We selected a number of functionally important 21OH amino acid substitutions, found in patients with congenital adrenal hyperp
For ∼50 years mixtures of cobalt(II) and manganese(II) acetates with sodium bromide or hydrobromic acid in acetic acid have been used as catalysts for the homogeneous aerobic oxidation of alkylaromatic compounds. They are known to be stable mixtures. While characterizing this mixture via EXAFS, it was thus surprising to observe an unexpected change in the color of the reaction mixture from deep bl
Available studies on visual field disturbances in diabetic retinopathy have shown conflicting results, obtained with different and often non-comparable techniques. We have studied visual fields at different stages of diabetic retinopathy with modern sensitive computerized technique taking precautions to limit disturbing effects of random field variation and lack of perimetric experience. Sixty-thr
□ Total hip arthroplasty (THA) registers are established in several countries to collect data aiming to improve the results after THA. Monitoring of adverse outcomes after THA has focused mainly on revision surgery, but patientreported outcomes have also been investigated. □ Several surgery-related factors influencing the survival of the THA have been thoroughly investigated and have changed clini
The brain tissue has only a limited capacity for generating new neurons. Therefore, to treat neurological diseases, there is a need of other cell sources for brain repair. Different sources of cells have been subject of intense research over the years, including cells from primary tissue, stem cell-derived cells and reprogrammed cells. As an alternative, direct reprogramming of resident brain cell
Purpose: Children’s results on school-related achievements tests, such as aspects of math, reading and writing, have been shown to decline following a lengthy summer vacation. Few studies have investigated whether this also applies to vocabulary skills. The purpose of this study is to investigate how lexical organization and retrieval, assessed by a semantic verbal fluency (SVF) task, develops dur
Public transport is an important part of the transition to a more sustainable future. The increasingly market-oriented public transport companies today market themselves with a wealth of messages in multiple channels such as direct mail, websites and apps. This communication is part of the influence that the (potential) traveler is exposed to, yet little research and testing is carried out in orde
