Japanese macaques (Macaca fuscata) exhibit a suite of stone handling behaviours (SHB, e.g. rolling, pounding, etc.) that lack an obvious instrumental function. As SHBs appear to be socially transmitted, previous research has focused on evolutionary theories of tool use and cumulative culture. It has been assumed that SHBs in general represent a form of solitary play whose function is to hone and m

Moraxella catarrhalisis a human respiratory pathogen that causes acute otitis media in children and is associated with exacerbations in patients suffering from chronic obstructive pulmonary disease (COPD). The first step inM. catarrhaliscolonization is adherence to the mucosa, epithelial cells, and extracellular matrix (ECM). The objective of this study was to evaluate the role ofM. catarrhalisint

A 3D model at microscale by the lattice Boltzmann method (LBM) is proposed for part of an anode of a solid oxide fuel cell (SOFC) to analyze the interaction between the transport and reaction processes and structural parameters. The equations of charge, momentum, heat and mass transport are simulated in the model. The modeling geometry is created with randomly placed spheres to resemble the part o

State-of-the-art laser frequency stabilization is limited by miniscule length changes caused by thermal noise. In this work, a cavity-length-insensitive frequency stabilization scheme is implemented using strong dispersion in a 21 mm long cavity with a europium-ion-doped spacer of yttrium orthosilicate. A number of limiting factors for slow light laser stabilization are evaluated, including the in

Recent research provides new perspectives on large-scale Early Holocene human interaction within Eurasia, based on ancient DNA or lithic technology. But the extent of regional human mobility is not well known. In this study, we combined two different approaches to investigate regional mobility and social networks in southern Scandinavia. We analyzed strontium isotopes in human teeth and regional l

Atomic layer deposited (ALD) TiO2 thin films have a wide range of applications in photonics which are, however, limited by the chemical instability of the amorphous as-deposited TiO2. Post-deposition annealing is required for improving the performance by inducing phase transitions and oxide defects. ALD precursor traces remaining in the TiO2 film affect the thermally-induced processes but the unde

It is a common strategy to predict oncogenes by differential analysis between somatic mutations and background mutations. Most previous methods only utilize mutations in the cancer population to model its background mutation, which have an obvious bias. A recent method, DiffMut, improves this issue by conducting differential mutational analysis with both mutations in the cancer population and the

BACKGROUND AND OBJECTIVES: Stroke genetic research has made substantial progress in the past decade. Its recovery application, however, remains behind, in part due to its reliance on the modified Rankin Scale (mRS) score as a measure of poststroke outcome. The mRS does not map well to biological processes because numerous psychosocial factors drive much of what the mRS captures. Second, the mRS co

We investigate the impact of a galaxy’s merger history on its system of satellites using the new VINTERGATAN-GM suite of zoom-in hydrodynamical simulations of Milky Way-mass systems. The suite simulates five realizations of the same halo with targeted ‘genetic modifications’ of a z ≈ 2 merger, but resulting in the same halo mass at z = 0. We find that differences in the satellite stellar mass func

A small wind power plant connected to the grid has been modeled in Modelica/ Dymola and controlled using external controllers written in C++. The small wind power plant consists of three wind power units with a nominal power of 3kW and one grid connection interconnected with an internal DCgrid. All the controls needed for control and optimization for the operation of the individual parts in the pl

Under våren 2013 har en hydrogeologisk kartering gjorts av grundvattenmagasinet Hultan i Sjöbo kommun, södra Skåne. Projektet har utförts på uppdrag av Sveriges geologiska undersökning som en del i arbetet med ett av Sveriges miljömål; Grundvatten av god kvalitet. Undersökningen har innefattat brunnsinventering av enskilda brunnar i området, provtagning och analys av grundvattnet i två mätpunkter,During spring 2013 mapping of the ground water has been done in Hultan in Sjöbo municipality, south Scania. The project is an assignment from Geological Survey of Sweden as a part of the work with one of Sweden´s environmental quality objectives; Groundwater of good quality. The study has included inventory of private wells in the area, a collection of samples and analysis thereof of the groundwat

Popular science Mauritania and Senegal are two countries located at the border of West Africa. Their urban population is increasing significantly since the last decades because of rural immigration and natural growth of urban population. Using GIS and remote sensing techniques, the rate of urbanized area is estimated for two coastal cities of Mauritania (Nouadhibou and Nouakchott) and for three co

Populärvetenskaplig sammanfattning Arsenik finns överallt i naturen och släpps även ut genom industrier. Det är ett klassiskt gift som färgat historien, men som även använts inom medicin. Arsenik är det enda kemiska cancerogena ämne som ger hudcancer vid förtäring. Det har även använts inom industrin under en lång tid, och deponering av arsenikhaltigt material kommer att orsaka stora miljöproblem.Arsenic is present everywhere in the world. It is found in the bedrock and is discharged by industries. Differents forms of arsenic varies in toxicity, the inorganic form is much more toxic then the organic form. The inorganic form is most common in drinking water and groundwater, meanwhile the inorganic form can occasionally be found in reasonable large quantities in fish and seafood. Today milli

The aim of this study was to research how school counselors work and how they interpret and implement the existing guidelines from Skolverket and Socialstyrelsen. The study is also aimed to investigate what circumstances are influential for the school counselors' ability to implement the guidelines. The method of semi-structured interviews was chosen to allow us to investigate how school couns

Denna uppsats analyserar hur synen på straffets ändamål kommer till ut- tryck i Straffreformutredningen (SOU 2025:66 En straffreform). Syftet är att undersöka vilka straffteoretiska principer som får störst genomslag i utred- ningen och dess tillhörande direktiv, samt vad denna riktning reflekterar för grundläggande föreställningar om straffets funktion. Särskilt fokus ligger på hur straff, i synnThis thesis analyses how the purpose of punishment is articulated in ”Straff- reformutredningen”(the report for the proposed criminal law reform in Swe- den, SOU 2025:66). The aim is to examine which penal theories gain the greatest influence in the report and what this direction reflects in terms of underlying conceptions of the purpose of punishment. Particular attention is paid to how punishmen
