We present an in-depth investigation of laser-induced grating spectroscopy (LIGS) for temperature measurements in practical applications using a narrow-band dye laser with 760 nm wavelength and a pulse duration of 8 ns as the source for the pump beams creating the laser-induced grating. The pump laser wavelength was set to be either resonant with the (Formula presented.) transition from the (Formu

Recently, a 1.83 Å crystallographic structure of nitrogenase was suggested to show N2-derived ligands at three sites in the catalytic FeMo cluster, replacing the three μ2 bridging sulfide ligands (two in one subunit and the third in the other subunit) (Kang et al. in Science 368: 1381–1385, 2020). Naturally, such a structure is sensational, having strong bearings on the reaction mechanism of the e

Svenska Akademiens ordbok (SAOB) är en historisk och samtidsspråklig ordbok som beskriver det svenska språket från 1521 fram till nutid. Projektet har pågått sedan slutet av 1800-talet och närmar sig nu sin fullbordan. När en komplett ordbok från A–Ö är färdig börjar det omfattande arbetet med att uppdatera och revidera ordboksinnehållet. Därmed finns det för första gången på 125 år möjlighet att

There is an urgent need for radical transformations of unsustainable socio-technical systems, such as food, mobility, and housing. These transformations will not take place without new policies and research. In order to achieve these transitions, learning must be a central feature based on thorough evaluations of the actions taken. Evaluations have been conducted and studied for decades, but tradi

Understanding energy transport in metal halide perovskites is essential to effectively guide further optimization of materials and device designs. However, difficulties to disentangle charge carrier diffusion, photon recycling, and photon transport have led to contradicting reports and uncertainty regarding which mechanism dominates. In this study, monocrystalline CsPbBr3 nanowires serve as 1D mod

Precipitation over the Tibetan Plateau (TP) has major societal impacts in South and East Asia, but its spatiotemporal variations are not well understood, mainly because of the sparsely distributed in situ observation sites. With the help of the Global Precipitation Measurement satellite product IMERG and the ERA5 dataset, distinct precipitation seasonality features over the TP were objectively cla

The reaction kinetics of hydrogen-abstraction reactions from methoxymethanol (CH3OCH2OH) by hydrogen (Ḣ) atom, hydroxyl (ȮH), hydroperoxyl (HȮ2), methyl (ĊH3) and methoxyl (CH3Ȯ) radicals, and decomposition of the related hydroxyl-methoxyl-methyl (CH3OĊHOH), hydroxymethoxyl-methyl (ĊH2OCH2OH) and methoxyl-methoxy (CH3OCH2Ȯ) radicals, have been investigated in this study through high-level ab initi

Purpose: The purpose of this study is to investigate the effects of film holes’ arrangements and jet Reynolds number on flow structure and heat transfer characteristics of jet impingement conjugated with film cooling in a semicylinder double wall channel. Design/methodology/approach: Numerical simulations are used in this research. Streamlines on different sections, skin-friction lines, velocity,

Background: Ice hockey players often undergo arthroscopic treatment for femoroacetabular impingement syndrome (FAIS); however, only a few studies have reported postoperative patient-reported outcomes. It has been debated whether player position is related to FAIS. Purpose: To evaluate the change in patient-reported outcome measures (PROMs) in high-level ice hockey players from presurgery to 2 year

We welcome Raymond et al.’s invitation to further discuss the ‘pragmatics’ of relational thinking in sustainability science. We clarify that relational approaches provide distinct theoretical and methodological resources that may be adopted on their own, or used to enrich other approaches, including systems research. We situate Raymond et al.’s characterization of relational thinking in a broader

This research investigated social interactions within small significant networks across a range of higher education settings to determine their role in supporting improvements to assessment. Thirty-four academic staff from three higher education settings (Australia, Canada and Sweden) provided assessment change examples and drew network diagrams to explain their interactions. Significant social in

Alternative reproductive tactics (ARTs) have provided valuable insights into how sexual selection and life history trade-offs can lead to variation within a sex. However, the possibility that tactics may constrain evolution through intralocus tactical conflict (IATC) is rarely considered. In addition, when IATC has been considered, the focus has often been on the genetic correlations between the A

The role of economic freedom in national and sub-national development has been studied extensively in both cross-country and in cross-regional studies and used to explain differences in a wide array of economic outcomes. These findings motivated us to construct an index of economic freedom for the regions of the Russian Federation (EFRF). This paper presents the EFRF index and describes the method

Nationalmuseum öppnades 1866 och var del av ett nationalistiskt färgat och normskapande projekt. Analysen av de som deltog i inköpsnämnds konsekrerande beslut under perioden 1890–1920 kring vilken svensk konst som skulle införlivas i museets samling är licentiatuppsatsens grund.This licentiate study looks at the Nationalmuseum as a consecrating institution within the Swedish field of art between 1890 and 1920.

We are interested in complex electronic structures of various atomic and ionics systems. We use an ab initioapproach, the multiconfigurational Dirac-Hartree-Fock (MCDHF), to compute atomic structures and properties.We contribute in three main ways to the already existent literature: by developing and implementing originalcomputer programs, by investigating possibilities of alternative computationa
