We have used approximately 40 fs pulses from a Ti:sapphire laser to investigate the ultrafast energy transfer and relaxation dynamics in the light-harvesting pigment-proteins of photosynthetic purple bacteria. Our results reveal two new features, not earlier observed in light-harvesting pigments: (1) ultrafast relaxation characterized by a time constant of approximately 20 fs, which we interpret a
Archived radar data has various applications, though it is often underutilised. Nevertheless, this information has the possibility to aid in the development of accurate and relevant climate adaptation tools, inform climate-resilient urban development strategies, and numerous other personal and societal applications. Our work in the RadClim Baltic Sea Region (BSR) project established the potential
The Euro50 is a proposed 50m extremely large telescope for optical and infrared wavelengths. To study and predict the performance of the complete telescope system, an integrated model combining the structural model of the telescope, optics models, the control systems and the adaptive optics has been established. Wind and atmospheric disturbances are also included in the model. The model is written
We sought to evaluate the experiences and knowledge of health care providers in Sweden regarding female genital cutting (FGC) as a health issue. Questionnaires (n = 2,707) were sent to providers in four major cities in Sweden and evaluated by means of descriptive statistics. Twenty-eight percent (n = 769/2,707) responded, of whom 60% had seen such patients. Seven providers, including 2 pediatricia
Sustainable groundwater resources management in arid areas requires early and immediate action to prevent further negative impacts on these resources. The persistent decline in the quantity and quality of groundwater in many countries has been leading to severe challenges in the present and future. In this research, the factors affecting groundwater salinization in a coastal aquifer were evaluated
Many iterative optimization algorithms involve compositions of special cases of Lipschitz continuous operators, namely firmly nonexpansive, averaged, and nonexpansive operators. The structure and properties of the compositions are of particular importance in the proofs of convergence of such algorithms. In this paper, we systematically study the compositions of further special cases of Lipschitz c

Background: Integration of second-generation (2G) bioethanol production with existing first-generation (1G) production may facilitate commercial production of ethanol from cellulosic material. Since 2G hydrolysates have a low sugar concentration and 1G streams often have to be diluted prior to fermentation, mixing of streams is beneficial. Improved ethanol concentrations in the 2G production proce
Synucleinopathies, characterized by intracellular aggregation of α-synuclein protein, share a number of features in pathology and disease progression. However, the vulnerable cell population differs significantly between the disorders, despite being caused by the same protein. While the vulnerability of dopamine cells in the substantia nigra to α-synuclein over-expression, and its link to Parkinso
The Wilms tumor gene (WT1) encodes a zinc-finger containing transcription factor present in primitive hematopoietic progenitor cells. WT1 is also highly expressed in most cases of acute myeloid leukemia. Moreover, WT1 can interfere with induced differentiation of leukemic cell lines. These data suggest a function of WT1 in the maintenance of a primitive phenotype and a role in leukemogenesis by in
My purpose in this article is to make a contribution to what the legal philosopher H.L.A. Hart (1907-1992) has to say about providing a sociological understanding of law and to apply Hart's theory in relation to a specific area of law. The specific legal area consists of the violation compensation that victims of crime can obtain from the Crime Victim Compensation and Support Authority in Sweden.
High-profile bribery scandals that involve powerful people and large sums of money are often the object of general indignation and legal action. When it comes to bribery of the everyday kind, however, it is far less obvious which gifts should be seen as bribes, be it in a moral or legal sense. Legal cases of this kind almost always include voices that strive to refute accusations of bribery. This

Tidigare forskning har visat att patienter inom psykiatrin är föremål för kränkande behandling och oetiskt bemötande från personalen, där stigmatisering av psykisk sjukdom ses som en bidragande faktor. Föreliggande studie ämnade att undersöka bemötandebrister inom den svenska vuxenpsykiatrin. Syftet var att identifiera riskfaktorer för kränkande behandling och olika former av oetiskt bemötande av
The design of technologies, built environments, products, or services can result in inequalities, exclusion, and discrimination, possibly because designers–often unintentionally–reproduce social norms through their designs. This strongly relates to engineering and design educations, preparing future professionals and contributing to sustainable societies. The aim of this paper is to introduce and
