Den växande efterfrågan på hållbara förpackningslösningar har ökat fokus på återvinningsbarhet av plastkomponenter, inklusive plastlock. Graphic Packaging International (GPI) syftar till att göra sina förpackningar mer återvinningsbara. Vissa av deras kunder är dock ännu inte redo att byta från plast till papper. En lovande möjlighet är att göra plastlocket helt avtagbart, vilket möjliggör enklareThe growing demand for sustainable packaging solutions has increased the focus on recyclability of plastic components, including plastic lids. Graphic Packaging International (GPI) aims to make their packaging more recyclable. However, some of their customers are still not ready to switch from plastic to paper yet. One promising opportunity is to make the plastic lid fully removable, allowing easi

This study provides a simulation-based comparison of two energy storage alternatives, lithium-ion battery storage and a timer controlled domestic hot water (DHW) tank, within a Swedish residential context. The timer strategy explores the use of low-cost thermal storage to reduce electricity costs, especially in light of changing photovoltaic (PV) incentives. Different scenarios are modelled to com

Bakgrund. Industrierna utsätts för allt större press att anpassa sig till de håll- barhetsregler som införs. Detta tvingar industrierna att utmana de traditionella tillverkningsprocesser och hitta sätt att göra dem mer hållbara. I de traditionella industrierna används mycket kylvätska, som har stor inverkan på både den miljön och den sociala hållbarheten. Två produktionsmetoder uppvisar betydande Background. Industries are facing increasing pressure to adapt to sustainability regulations being put in place. This forces industries to rethink traditional manufac- turing operations and find ways to make them more sustainable. In the traditional industries there are a lot of coolants being used, these have a big impact on both the environment sustainability as well as social sustainability. Tw

In order for Software Configuration Management (SCM) tools to provide good traceability links there is usually a great deal of manual effort required. The result is that data becomes unreliable, inconsistent and in many cases nonexistent. The main focus in previous research in this area has been to make general tools which can provide traceability between any type of configuration artifact in any

Predicting live birth after the first IVF/ICSI treatment is challenging, as many factors may interact to affect IVF/ICSI outcomes. Adenomyosis is one factor that impacts live birth rates. Machine learning algorithms have been shown valuable for detecting complex dependencies and predicting outcomes in different clinical settings. We aimed to develop a prediction model for live birth after IVF/ICSI

Salinity gradient energy (SGE) can play an important role in the energy transition from fossil-based sources to renewable sources. Its potential is estimated to be around 625 TWh·a-1 corresponding to 3% of global electricity consumption [1]. SGE sources are most abundant in the estuaries where rivers meet seawater. However, it is also available in different forms such as brackish water, brine etc

The mufti-layer dynamic soil chemistry SAFE model was used to study the dynamics of recovery in the F1 catchment at Lake Gardsjon, Sweden. The influence of (F) sulphate adsorption, and (2) changes in marine deposition, oil model predictions of recovery was studied. Sulphate adsorption/desorption in SAFE is modeled by all isotherm in which sulphate adsorption is dependent oil both the sulphate conc

This paper suggests an infrastructure perspective, as suggested by Star and Bowker (2006), as an analytical framework for studying the research evaluation landscape. An infrastructure is suggested to be understood, not as a concrete technology, but as a system of contextual factors including ‘Actors/Stakeholders’, ‘Technical systems’, and ‘Evaluation practices’. How the framework can be operationa

The visual systems of many animals, particularly those active during the day, are optimized for high spatial acuity. However, at night, when photons are sparse and the visual signal competes with increased noise levels, fine spatial resolution cannot be sustained and is traded-off for the greater sensitivity required to see in dim light. High spatial acuity demands detectors and successive visual

The WHO has ranked environmental hazardous exposures in the living and working environment among the top risk factors for chronic disease mortality. Worldwide, about 40 million people die each year from noncommunicable diseases (NCDs) including cancer, diabetes, and chronic cardiovascular, neurological and lung diseases. The exposure to ambient pollution in the living and working environment is ex

The thesis concerns glycosyl transfer with use of b-glycosidases, most of them from hyperthermophilic organisms. Both optimisation of the reaction conditions and protein engineering in terms of site-directed mutagenesis were used to improve b-glycosidase-catalysed reactions. The first part of the work deals with conversion of lactose into valuable products such as galacto-oligosaccharides (GOS) an

Popular Abstract in Swedish De perifera nervstammarna i extremiteterna förmedlar signaler, dels till muskler, dels från känselkroppar som är belägna i bl a huden. Nervstammarna kan av olika orsaker utsättas för skador orsakade av vassa eller skärande föremål eller av olika typer av slitvåld. Nervskador ger ett mycket stort handikapp för den enskilde patienten som förlorar muskelfunktion och känselNerve injuries have a profound impact on individuals, suffering for the patients and induce cost for society. When dealing with severe nerve injuries that create a gap between nerve segments or when the injury is at the brachial plexus level, the clinical alternatives are limited. The brachial plexus model and its branches in the forelimb was evaluated as an experimental model for studies of nerve

BACKGROUND AND PURPOSE: Radiotherapy treatment planning algorithms continue to develop and current planning systems typically offer simpler, but faster, algorithms, which may be 2, 2.5 or 3D in modelling scatter, but which do not model electron transport (type a) and more accurate algorithms which aim to be fully 3D, i.e. which model 3D scatter and also model electron transport (type b). A range o

One major problem in global governance is the specification of decision-making rules for international and regional organisations to coordinate the states of the world. Various organisations use different decision-making rules, and the properties of these rules may be compared systematically in terms of the power index approach. The power index solution concept of N-person games may be employed to
