Learning from incidents is important for improving safety. Many companies spend a great deal of time and money on such learning procedures. The objectives of this paper are to present some early results from a project aimed at revealing weaknesses in the procedures for learning from incidents and to discuss improvements in these procedures, especially in chemical process industries. The empirical
De stora miljö- och samhällsproblemen kommer inte ensamma. De är sammankopplade på olika sätt. Detta innebär utmaningar men ger också möjligheter att utveckla åtgärder och lösningar. Det gäller både för klimatfrågan och frågan om att motverka förlusten av biologisk mångfald och ekosystem. Kunskapens betydelse för att hantera dessa och andra aspekter är ovärderlig, såväl kring specifika frågeställn
BACKGROUND: Iodine has been suggested to protect against breast cancer, but there are no epidemiologic studies on individual risk. An interesting finding is that in areas where the exposure to both selenium and iodine are high (e.g., Japan), the risk of breast cancer is lower than in areas where selenium is high and iodine low (e.g., United States), or in areas where both are low (e.g., Northern E
The effect of heat treatment on the soluble protein content in oat groats (Kerstin commercial variety) was evaluated using asymmetric flow field-flow fractionation (AF4) in combination with online multiangle light scattering (MALS) and UV detection. The AF4 method was used to separate the monomeric proteins from globulin hexamer and aggregate proteins and beta-glucan polysaccharides in the soluble
We consider continuous review inventory systems with general doubly stochastic Poisson demand. In this specific case the demand rate, experienced by the system, varies as a function of the age of the oldest unit in the system. It is known that the stationary distributions of the ages in such models often have a strikingly simple form. In particular, they exhibit a typical feature of a Poisson proc
In the light of the environmental challenges society is facing it is important thatboth products and their packaging systems are optimised from an environmental perspective. Previous research highlights that environmental optimisation of packaging requires an integrated assessment of product and packaging together.Theory on green packaging development (GPD) is comprehensive and there areexamples o
The opportunity of integrating pervaporation within the concept of waste water treatment to recover organic compounds has been widely recognized. Within this paper a process simulation is developed as a design tool to analyse and optimize the process of hydrophobic pervaporation. In the simulation the mass transfer through the membrane and concentration boundary layer are described using a resista
Currently, no ideal prostate cancer (PCa) diagnostic or prognostic test is available due to the lack of biomarkers with high sensitivity and specificity. There is an unmet medical need to develop combinations of multiple biomarkers which may have higher accuracy in detection of PCa and stratification of aggressive and indolent cancer patients. The aim of this study was to test two biomarker gene p
The society of today is highly dependent on technical infrastructures. Several incidents around the world the last decades have clearly highlighted the major effects technical infrastructure breakdowns have on life, health and economy of society. The vulnerabilities inherent in our technical infrastructures must be addressed in a proactive manner; it is not feasible to wait for major incidents to
Klimatförändringarna gör världen successivt varmare, förändrar nederbördsmönster, höjer havsytenivån, med mera. Klimatet har redan förändrats och i alla fall en viss fortsatt förändring är oundviklig på grund av tidigare och pågående växthusgasutsläpp. Hur stora klimatförändringarna blir på sikt beror i första hand på beslut om och åtgärder för att minska vår klimatpåverkan, det vill säga utsläpp
The need to integrate climate change adaptation (CCA) considerations into disaster risk management (DRM) systems is widely recognised. However, successful integration, and thus the implementation of integrated planning measures, is difficult in practice. To understand and reduce the problems encountered, it is important to investigate systemic challenges. These challenges are rooted in the interac
Sweden’s Art and Music Schools offer courses and activities after the school day. Besides that, Art and Music Schools also work in collaboration with compulsory schools, including training schools and special schools. The investigation report on Art and Music Schools, part of the national policy process, focuses on the ‘after school’ parts of Art and Music Schools, leaving the other parts untouche
We present age- and gender-specific normative bone status data evaluated by quantitative ultrasound (QUS) in the calcaneus with the Lunar Achilles device and compare these estimates with bone mineral content (BMC) and bone mineral density (BMD) estimated by dual X-ray absorptiometry (DXA). Included were a sample of 518 population-based collected Swedish girls and 558 boys aged 6-19 years. QUS meas
For better or worse work plays a major role in both the psychological and thephysical well-being in peoples’ lives. Work can be a source of meaning, joy and self fulfilment, or a cause of distress and illness. This holds true even in wealthy parts ofthe world with a long tradition of research and governmental actions to achieve a goodworking environments. For example, in Sweden an average of 35 pe
