Seawater intrusion has been aggravated due to anthropogenic reasons, such as sea level rise and over abstraction of groundwater, which is spoiling the groundwater sustainability. This study focused on a negative hydraulic barrier using a barrier well as a countermeasure. Two lab-scale experiments and a numerical analysis with a 2-D solute transport model were conducted to examine an optimal locati
Every day about 1 trillion new blood cells are formed, of which the majority are red blood cells. This depends on a small number of hematopoietic stem cells that are able to both self-renew to maintain the stem cell pool, and to mature into all types of mature blood cells. Anemia is associated with aging, chronic infections and cancer, and significantly impacts quality of life and survival. It is

Uncoupling protein 2 (UCP2) is a protein, located in the inner mitochondrial membrane, which dissipates the proton gradient of this membrane and uncouples respiration from oxidative phosphorylation. We found, by in situ hybridisation, UCP2 mRNA to be located in the proliferating zone of the mucous neck cells in the fundus part of the rat stomach. We also found that UCP2 expression in fundus was si
The argument in this paper is that Hobbes’ theory of freedom in Leviathan allows for four ways of being free to act – corporal freedom by nature, freedom from obligation by nature, the freedom to disobey, and the freedom of no-rule – each corresponding to a particular absence, some of which make sense only in the civil state. Contrary to what some have claimed, this complexity does not commit Hobb
Free energy perturbations have been performed on two blue copper proteins, plastocyanin and nitrite reductase. By changing the copper coordination geometry, force constants, and charges, we have estimated the maximum energy with which the proteins may distort the copper coordination sphere. By comparing this energy with the quantum chemical energy cost for the same perturbation on the isolated cop
Radiotherapy is commonly used for cancer treatment, given to approximately half of all cancer patients in Sweden. Despite its widespread usage, there is currently no non-invasive and reliable imaging method that can identify regions of radiation resistance. These regions may be identified by hypoxia, given that radiobiological research has demonstrated a significant correlation between oxygen leve
Generation of good non-repeatable and non-predictable random number sequences is of increasing importance, both in security applications and in simulations. A novel, compact system is presented in which a secure random number is generated by sampling a chaotic system and using this bitstream as the input to a pseudo-random generator. An optional hash function can be used on the seed in order to de

Tema 2022 De senaste åren har en rad initiativ* tagits för att lyfta fram hållbarhet som ett flerdimensionellt koncept, som omfattar både miljömässiga, sociala och ekonomiska dimensioner. Syftet har ofta varit att integrera de tre hållbarhetsdimensionerna i ett enhetligt system och omvandla miljömässiga värden till siffror. På så vis har man velat göra det möjligt att integrera naturen och de värd

Superconducting devices, based on the Cooper pairing of electrons, play an important role in existing and emergent technologies, ranging from radiation detectors1,2 to quantum computers3. Their performance is limited by spurious quasiparticle excitations formed from broken Cooper pairs4–12. Efforts to achieve ultra-low quasiparticle densities have reached time-averaged numbers of excitations on th
Free space optics is an interesting alternative for telemetry with medical implants, due to the high data bandwidths available at optical frequencies. Especially implanted brain-computer interfaces gives rise to large data sets that needs to be transmitted transcutaneous. In this paper we show that it is possible to establish such a link at near-IR wavelengths using a modulated reflector in the im
In this study, a method was developed for determination of the free concentration of 4-isobutylacetophenone, a toxic degradation product of ibuprofen, in river and sewage water samples from Sweden. Sample preparation and analysis were performed by a hollow-fibre microporous membrane liquid-liquid extraction (HF-MMLLE) set-up and gas chromatography-mass spectrometry (GC-MS), respectively. In this n
High flux extreme ultraviolet (XUV) sources like the free electron laser (FEL) in Hamburg (FLASH) offer the possibility of diffractive imaging of small objects. Irrespective of whether the diffraction is based on the detection of photons or photoelectrons, it is required that the measurement is done in the reference frame of the molecule meaning that, for a sample of several molecules, it is neces
We recently described a method to compute accurate quantum mechanical free energies [Rod, T. H.; Ryde, U. Phys. Rev. Lett. 2005, 94, `138302]. The method, which we term quantum mechanical thermodynamic cycle perturbation (QTCP), employs a molecular mechanics force field to sample phase space and, subsequently, a thermodynamic cycle to estimate QM/MM free energy changes. Here, we discuss the method
(H2O)(N) clusters generated in a supersonic expansion source with N similar to 1000 were core ionized by synchrotron radiation, giving rise to core-level photoelectron and Auger electron spectra (AES), free from charging effects. The AES is interpreted as being intermediate between the molecular and solid water spectra showing broadened bands as well as a significant shoulder at high kinetic energ
