The properties of iron (Fe) complexes and compounds in the environment influence several central processes, e.g., iron uptake, adsorption/desorption of contaminants and nutrients, and redox transformations, as well as the fate of of natural organic matter (NOM). It is thus important to characterize Fe species in environmental samples. Synchrotron-based extended X-ray absorption fine structure (EXA
High-spin states in (120)Te were populated in the reaction (80)Se((48)Ca, alpha 4n)(120)Te at a beam energy of 207 MeV and gamma-ray coincidences were measured using the Gammasphere spectrometer. The previously known level scheme is extended to higher spin and new interband transitions and side-feeding branches are established. Five highly deformed rotational bands, extending up to almost I = 50,
We have studied the (0001) surface termination of Rh2O3 on a Rh(111) single crystal using a combination of high resolution core level spectroscopy, low energy electron diffraction, scanning tunneling microscopy and density functional theory. By exposing the Rh(111) to atomic oxygen we are able to grow Rh2O3 layers exposing the (0001) surface. The experiments support the theoretical predictions sta
Reaction of tri(2-furyl) phosphine (PFu(3)) with [Re-2(CO)(10) (n)(NCMe)(n)] (n = 1, 2) at 40 degrees C gave the substituted complexes [Re-2(CO)(10) (n)(PFu(3))(n)] (1 and 2), the phosphines occupying axial position in all cases. Heating [Re-2(CO)(10)] and PFu(3) in refluxing xylene also gives 1 and 2 together with four phosphido-bridged complexes; [Re-2(CO)(8) (n)(PFu(3))(n)(mu-PFu(2))(mu-H)] (n
This paper presents two class-C CMOS VCOs with a dynamic bias of the core transistors, which maximizes the oscillation amplitude without compromising the robustness of the oscillation start-up, thereby breaking the most severe trade-off in the original class-C topology. An analysis of several different oscillators, starting with the common class-B architecture and arriving to the proposed class-C
Tubes form the basic structure of several organs like lungs, kidneys, glandular organs like the pancreas, mammary and salivary glands. Tube formation involves a series of dynamic and interdependent cellular processes, including cytoskeletal reorganization, assembly of intercellular junctional complexes, and cell polarization. Understanding how cells polarize and coordinate tubulogenesis during org
Den här artikeln för fram digitaliseringen och konsekvenserna av Internet som ett studieobjekt med inneboende möjligheter för metodutveckling inom rättssociologi och den bredare rättsvetenskapen – vilket i sin tur adresserar en teoretisk potential. Artikeln lyfter fram tre aspekter som det argumenteras för är av särskild vikt att adressera: 1.) de stora datamängdernas och mätbarhetens metodologisk
Studies of non-model species are important for understanding the molecular processes underpinning phenotypic variation under natural ecological conditions. The common buzzard (Buteo buteo; Aves: Accipitriformes) is a widespread and common Eurasian raptor with three distinct plumage morphs that differ in several fitness-related traits, including parasite infestation. To provide a genomic resource f
The world supply and turnover of copper was modelled using simple empirical estimates and a COPPER systems dynamics model developed for this study. The model combines mining, trade markets, price mechanisms, population dynamics, use in society and waste as well as recycling, into a whole world system. The degree of sustainability and resource time horizon was estimated using four different methods
Breast cancer exhibits significant molecular, pathological, and clinical heterogeneity. Current clinicopathological evaluation is imperfect for predicting outcome, which results in overtreatment for many patients, and for others, leads to death from recurrent disease. Therefore, additional criteria are needed to better personalize care and maximize treatment effectiveness and survival.

I såväl media som inom myndigheter och organisationer har det under de senaste åren i allt högre grad uppmärksammats att migrerande arbetskraft inom jordbruket/den gröna näringen eventuellt används på ett sätt som kan strida mot arbetsrättsliga och sociala regleringar.Avsikten med föreliggande studie är framförallt att sammanställa den forskning som finns avseende olika arbetslivs- och arbetsmiljö
The literature data on the region at about 55-60 at.% Cu in the Cu-In phase diagram is somewhat confusing. With Cu10In7 and Cu11In9, two intermetallic compounds have been reported whose structures are alike and both are reported to be stable over a similar temperature range. Here, we show that Cu10In7 can be synthesized and characterized in agreement with the study by Piao and Lidin. Moreover, the
We study the induced subgraph isomorphism problem and the general subgraph isomorphism problem for small pattern graphs. We present a new general method for detecting induced subgraphs of a host graph isomorphic to a fixed pattern graph by reduction to polynomial testing for nonidentity with zero over a field of finite characteristic. It yields new upper time bounds for several pattern graphs on f
Organotypic spinal cord slices from neonatal mammals could be a powerful model for evaluation of cell survival but also cell death mechanisms. The aim of this study was to establish an in vitro model for investigating cell survival and mechanism involved in cell death in neonatal spinal cord slices. The spinal cord was sliced and incubated into culture medium. The MTT assay was carried out to asse
Background: Food consumption is one of the most important drivers of environmental pressures. Adoption of healthy diets is suggested to be an option for less environmentally intensive food habits and improved public health. In particular, changes in meat consumption are believed to bring potential benefits. Objective: To quantify the impact of changes in meat consumption on the dietary contributio
In this paper, we address the problem of locating a target using multiple-input multiple-output (MIMO) radar with widely separated antennas. Through linearizing the bistatic range measurements, which correspond to the sum of transmitter-to-target and target-to-receiver distances, a quadratically constrained quadratic program (QCQP) for target localization is formulated. The solution of the QCQP is
In this work, we demonstrate how a lateral motion of a supported lipid bilayer (SLB) and its constituents can be created without relying on self-spreading forces. The force driving the SLB is instead a viscous shear force arising from a pressure-driven bulk flow acting on the SLB that is formed on a glass wall inside a microfluidic channel. In contrast to self-spreading bilayers, this method allow
Background: We found marked improvement of glycemic control and several cardiovascular risk factors in patients with type 2 diabetes given advice to follow a Paleolithic diet, as compared to a diabetes diet. We now report findings on subjective ratings of satiety at meal times and participants' other experiences of the two diets from the same study. Methods: In a randomized cross-over study, 13 pa
