Drinking water is an important source for trace elements intake into human body. Thus, the drinking water quality has a great impact on people's health and longevity. This study aims to study the relationship between drinking water quality and human health and longevity. A longevity county Mayang in Hunan province, China was chosen as the study area. The drinking water and hair of local centenarians ...

The fuel life cycle involves different phases of extraction/refinery (well to tank: WtT), transport (tank to propeller: TtP), and storage where each of these processes can add a specific amount of emissions to the overall LCCA inventory. During the extraction or operation of machinery on the raw material, the released amount of GHG components is undergoing a change in the generated emissions per ...

Dry covers can be applied above tailings to reduce and prevent formation of acid mine drainage and leaching of contaminants. Efficiency of covers is affected by different parameters, of which temperature change under climate change context is one. Here, a laboratory column leaching experiment was performed under four temperatures, 5, 10, 14, and 18 °C on unoxidized tailings from Ballangen, Norway. ...

In this study, the effect of temperature on the leaching of Cr, Cu, Fe, Ni and Zn from oxidized tailings, Ballangen deposit, Norway, was investigated by a laboratory batch leaching experiment. The leaching was conducted at four different temperatures 5°C, 10°C, 15°C and 20°C and 2 precipitation rates of 8 mm/week and 20 mm/week. The leachates from six leaching cycles were collected, and the concentra- ...

Due to the lack of sheltered area, Norwegian fish farms are expanding to more exposed and remote sites. The severe environmental conditions in exposed sites can increase the risk of structural failure during aquaculture operations. In the present study, the program FhSim is employed to conduct time-domain simulations to investigate structural responses of a single-cage and 1 × 4 multi-cage fish farm ...

Økt interesse for ferdsel i skredfarlig terreng gjennom ski- og brettkjøring, har økt risikoen for snøskredulykker. Skredvarslingen Varsom er en av de viktigste verktøyene man har i dag til å skaffe informasjon om vær- og snøforhold, planlegge tryggere turer og forhindre menneskelige feil. Dette fordrer effektiv risikokommunikasjon og riktige forutsetninger for å oppfatte den kommuniserte risikoen. ...

If disaster strikes, people who are nearby will very often contribute in the emergency response. Emergency responders will have to interact with unorganized volunteers. However, research on unorganized volunteers in emergencies has paid little attention on how to best utilize the average citizen. To contribute to better understanding of the interaction between actors present in emergencies we need ...

Debris flows are a mountain slope hazard relatively well studied in densely populated mountainous regions, while few investigations have been done in Arctic permafrost regions. In order to get a better understanding of the processes involved in such an envi-ronment, this work focused on debris flow hazards in the mountains close to Longyear-byen and Svea on Svalbard, Norway, situated at 78°N. A ...

Organisatorisk resiliens er et fagområde med stor akademisk interesse, dog er det fortsatt stor usikkerhet og lite konsensus om hva resiliens er og hvordan det er sammensatt. Det mangler empirisk forskning og et felles analytisk rammeverk til hvordan organisasjoner kan utvikle resiliens. Denne oppgaven er mitt bidrag til fagfeltet, hvor jeg går i dybden på hvordan utvalgte kommuner kan bygge en ...

Film fixed resistor is a basic unit in the electronic devices. As it is less frequently failed than other units such as capacitor, the reliability and robustness of it are less concerned both in the academics and in the industries. This paper investigates the endurance of the carbon film fixed resistor. The resistance shift and life of it under the escalated voltage stress level are the aim. A PCB ...
