Introduction: This study was performed to optimize extraction of lead, copper and zinc from seaweed using pressurized hot water, to investigate the selectivity and extractability of the extraction. Background: Pressurized hot water extraction is an environmentally sustainable method in comparison to more common extraction methods, such as distillation or solvent extraction, used with plant mater
Den här uppsatsen undersöker människors nyhetskonsumtion vid en krissituation i kontrast till vardagslivets nyhetsanvändning med utgångspunkt i jodelhotet mot Lunds universitet. För att få en förståelse för vad som sker med konsumtionen när vardagslivet krackelerar och en kris infinner sig har vi genomfört en kvalitativ publikstudie. För att förklara detta växelspel i konsumtionen har vi tagit sta
Spiders play a key role as predators in a wide range of terrestrial ecosystems. Their community composition is strongly affected by environmental gradients. The latitudinal diversity gradient concept states that diversity and species richness is negatively related to increasing latitude. This has been observed in spiders on a continental scale, but so far was not observed on a regional scale in Eu
China is generally regarded as a country that has successfully achieved rapid economic development and rapid urbanization over the last three decades. But, in the course of this process, spatial inequalities in the country and the rural-urban divide within the city increase. That has led to the consolidation of the country’s dual economic structure. In 2003, the Chinese government implemented the
Fourier transform infrared spectroscopy techniques were used to study the kinetics of gas-phase reactions of three lactones, γ-valerolactone (GVL), 2(5H)-furanone (2(5HF) and 3-methyl-2(5H)-furanone (3M2(5H)F) with Cl atoms, OH radicals and O3 respectively. The experiments were performed in a photochemical reactor at a total pressure of 700 Torr at room temperature (298±2 K). Both relative rate an
Birds endure ecological constraints during winter in temperate regions where critical resources vary significantly between urban and rural sites, influencing survival rate. Warmer temperatures and artificial food sources have led to an increase in urban avian winter abundance whereas birds in colder, rural ecosystems are more reliant on scarce natural food sources but subject to less human disturb
This thesis’ focus will be on the comic book series Locke & Key in a semiotic and an intertextual reading through a psychoanalytical framework. The comic series is described as a “psychological horror” and a main theme running across the six volumes is good versus evil, and a lot of the narrative is helped by magical keys. The keys have specific uses and help both sides gain more power. The ps
The aim of this master thesis project was to investigate the impact on drying kinetics of ultrasound during air drying by a new ultrasonic transducer, on which a patent application has been filed by CSIRO. Convection drying using hot air is currently the conventional method of drying in the industry due to its simplicity and low cost. To increase product quality, freeze drying utilises a vacuum bu
Researchers agree that there exist a close connection between export, foreign direct investment and economic growth, still they do not agree about the causal relationships between them. Latin America has over the last decades faced several economic crises. However, the continent has also been characterised by emerging economies, increased globalisation and trade liberalisation where export, foreig
Background and Research Question Historically, Lindab has largely focused its efforts on the production, but as a part of recent development in company strategy, supply chain management has gained more attention. In this regard, more attention has been given to stock reduction and minimizing total setup times to get a leaner production. Therefore, the company wants to investigate the current produ
This thesis analyses price relations in Malaysian energy and agricultural markets. In partic- ular interactions among prices for biodiesel, palm oil and crude oil were studied. The levels of the series are modeled by a standard vector autoregression set-up in combination with an impulse response analysis. A multivariate GARCH was utilized for identifying possible correlations among the volatilitie
Breast cancer is the most common type of cancer in women and there are different types of breast cancers. Although the survival among breast cancer patients has improved the last decade, there is still a large group of patients with a bad prognosis. In recent years, a new set of immunotherapies called immune checkpoint inhibitors targeting the regulatory receptors in T-cell activation and activity
Vetenskapliga artiklar föreslår att xylan är delvis bundet till proteinerna i dulse. Detta kan leda till minskad tillgänglighet av proteinerna och leda till svårigheter att smälta dessa i tarmen. Denna rapport har för avsikt att hitta och optimera metoder för extraktion av proteiner och metoder för att separera de proteiner och polysackarider som förekommer i dulse. Metoderna som används är hydrol
The research of the thesis was aimed towards investigating the possibility of implementing different control strategies for power electronic converters in a simulation environment. The different control modes were fitted into flexible models that were interconnected in various grid topologies. The software used in order to develop the simulation environment is called Dymola and presently does not
Problemdiskussion: Sektorn för olja och gas är inte särskilt mogen när det gäller kunskapen om försörjningskedjor. Det valda företaget för fallstudien, Maersk Drilling (MD), har problem med ett splittrat IT-landskap och dålig datakvalitet. Det har orsakat problem med ineffektiva och komplexa processer där det krävs onödig kommunikation, parallell inmatning av data, etc. Inom upphandlingar och inkProblem Discussion: The oil and gas sector is not very mature in terms of supply chain management. The chosen case company, Maersk Drilling (MD), has problems with a split IT-landscape with poor data quality. It has caused problems with inefficient and complex processes with much communication required, parallel information and more. Within procurement it translates to problems in spend managemen
This chapter draws on Lefebvre’s Rhythmanalysis and Production of Space as conceptual, political and metaphorical reservoirs to examine the way in which international protection provisions, as enshrined in international human rights law, are challenged and undermined by current EU migration policies of migration deterrence and containment. In the context of socio-spatial practice, Rhythmanalysis f
It is currently unclear how amyloid-β and tau deposition are linked to changes in synaptic function and axonal structure over the course of Alzheimer's disease. Here, we assessed these relationships by measuring presynaptic (synaptosomal-associated protein 25, SNAP25; growth-associated protein 43, GAP43), postsynaptic (neurogranin, NRGN) and axonal (neurofilament light chain) markers in the CSF of
