Evaluating soil strength by geophysical methods using P-waves was undertaken in this study to assess the effects of changed binder ratios on stabilization and compression characteristics. The materials included dredged sediments collected in the seabed of Timrå region, north Sweden. The Portland cement (Basement CEM II/A-V, SS EN 197-1) and ground granulated blast furnace slag (GGBFS) were used as

Light-level geolocators were used to record the annual migration cycles of black terns Chlidonias niger (9 individuals, 11 journeys) and common terns Sterna hirundo (7 individuals, 11 journeys) breeding in southernmost Sweden. The black terns used two different non-breeding (Oct–Mar) regions along the Atlantic coast of Africa, either north of the equator between Senegal and Liberia (3 individuals)

Change in Japanese foreign and security policy has long been characterized as “incremental”. However, Japan’s response to Russia’s 2022 invasion of Ukraine provides an opportunity to reconsider this paradigm. In the aftermath of the 2014 annexation of Crimea, then-Prime Minister Abe Shinzō chose not to put Crimea on the agenda, prioritizing instead relations with Russia. However, Prime Minister Ki

Transient concurrent flame spread over solid surfaces involves multiple interacting physical processes, where simplified modelling with effective parameter identification is still challenging. This study presents a modelling framework that combines scaling-based formulation with Bayesian parameter inference to quantitatively capture the transient behaviors of concurrent flame spread. Experimental

Lateglacial and Holocene summer sea-surface temperature (SST) variability in the northern North Atlantic was reconstructed based on diatom records from two sediment cores from the North Icelandic shelf. The temperature changes are discussed in relation to palaeoceanographic circulation patterns and past climatic changes. Modern diatom data from surface sediments from around Iceland and Southeast a

Public diplomacy (PD) scholars tend to consider two main principals: the country or agent that conducts PD (Actor A), and target groups in the host country in which PD is conducted (Actor B). The field currently lacks theories of how communications between Actors A and B can be disrupted by a third party, such as a group of motivated trolls, an organised advocacy group, or a hostile country and it

Ti3C2Tx MXene (or "MXene" for simplicity) has gained noteworthy attention for its metal-like electrical conductivity and high electrochemical capacitance-a unique blend of properties attractive toward a wide range of applications such as energy storage, healthcare monitoring, and electromagnetic interference shielding. However, processing MXene architectures using conventional methods often deals

The prospect of being able to efficiently inject large plasmids in insulin-producing beta cells is very attractive for diabetes research. However, conventional transfection methods suffer from high cytotoxicity or low transfection efficiency, which negatively affect their outcome. In contrast, nanostraw electroporation is a gentle method that can provide a high transfection efficiency while mainta

Denna uppsats kallad ”Medier i medierna” är författad av Mathias Kristiansson Hemmel och Josefin Seiz vid Institutionen för kommunikation och medier, Lunds universitet. I februari 2012 publicerades en artikel i Svenska Dagbladet som vi särskilt uppmärksammade. Artikeln var en del av en reportageserie och handlade om ett andligt medium som livnär sig på att coacha och vägleda människor som känner s

Dose calculations for treatment planning of photon beam radiotherapy require a model of the beam to drive the dose calculation models. The beam shaping process involves scattering and filtering that yield radiation components which vary with collimator settings. The necessity to model these components has motivated the development of multisource beam models. We describe and evaluate clinical photo

Popular Abstract in Swedish Värmebehandling (termoterapi) av tumör baseras på kunskap om den celldödande effekten av värme. Den har begränsats av svårigheten att kontrollera temperaturutbredningen så att en selektiv och tillräcklig effekt erhålls, och detta gäller särskilt djupt belägna tumörer. Interstitiell laser termoterapi (ILT) med Nd:YAG laser är en ny behandlingsform, som ger de tekniska föInterstitial laser thermotherapy (ILT) is a method well suited for selective local destruction of malignant tumours. In the present work, a laser thermotherapy system based on feedback temperature control of energy delivery (through computerised feedback system) was developed. Temperature control was excellent in experiments without carbonization and with preserved light penetration, whereas tempe

In aqueous solutions hydrophobically modified polyethylene glycol (HM-PEG) forms a transient polymer network held together by intermolecular hydrophobic associations. In the present investigation we have used NMR-diffusometry to study how the addition of methylated alpha-cyclodextrin (M-alpha-CD) influences the polymer network. The addit on of M-alpha-CD resulted in an increased mean self-diffusio

Telemedicine is becoming a reality as a result of improvements in technology and telecommunications. The task of the otolaryngological part of the pilot international telemedicine Litmed project was devoted to the establishment of telemedicine training and demonstration facilities in cooperation between the Departments of Otolaryngology of the Kaunas University of Medicine (Lithuania) and the Lund

Scatter correction in SPECT is important for improving image quality, boundary detection and the quantification of activity in different regions. This paper presents a comparison of four scatter correction methods, three using more than one energy window and one convolution-subtraction correction method using spatial variant scatter line-spread functions. METHODS: The comparison is based on Monte

Fabrication and characterisation of buried metal contacts in compound semiconductors are demonstrated. The contacts have been investigated due to their usage both as gates in transistors and as active or passive elements in novel devices. A detailed description of the processing conditions for fabrication of nm-sized W-structures in a lift-off process is given. These structures have been embedded

Popular Abstract in Swedish Många av dagens biotekniska processer syftar till att framställa protein. Det är proteinets användningsområde som är avgörande för vilka renhetskrav som ställs på produkten. I vissa fall måste proteinet vara helt fritt från föroreningar för att inte åstadkomma oönskade effekter. Vaccinframställning är ett exempel på en sådan tillämpning. För andra ändamål, t ex vid framTwo polymers, alginate and Eudragit S-100 were used as reversibly soluble-insoluble ligand carriers for the selective isolation of enzymes and lectins respectively. These two polymers have the inherent property of being precipitated under well defined conditions. Alginate was made insoluble by the addition of Ca2+ ions, and Eudragit S-100 by a pH shift. The polymers were modified with affinity lig

For some time, directional antennas have been considered to solve connectivity and interference issues in wireless networks. Several scenarios have been presented and often the conclusions drawn are positive, showing increase in capacity. However, to date there has been no effort to assess a holistic picture of the benefit/cost tradeoff and previous work mainly concerns either link scheduling or a

Most state-of-the-art natural gas fired combined cycle (NGCC) plants are triple-pressure reheat cycles with efficiencies close to 60 percent. However, with carbon capture and storage, the efficiency will be penalized by almost 10 percent units. To limit the energy consumption for a carbon capture NGCC plant, exhaust gas recirculation (EGR) is necessary. Utilizing EGR increases the CO2 content in t

Integrated cross-sectoral impact assessments facilitate a comprehensive understanding of interdependencies and potential synergies, conflicts, and trade-offs between sectors under changing conditions. This paper presents a sensitivity analysis of a European integrated assessment model, the CLIMSAVE integrated assessment platform (IAP). The IAP incorporates important cross-sectoral linkages between
