Experiments on manganese(II)- and nickel(II)-catalyzed oxidation of sulfur(IV) by oxygen in aqueous solution at pH 4.5 afford a direct measurement of the loss of sulfur(IV) during the oxidation in the natural pH-range of most atmospheric aqueous systems.Manganese(II)- and nickel(II)-catalyzed oxidation of sulfur(IV) by oxygen in aqueous solution at pH 4.5 has been studied, as a model for oxidation of sulfur(IV) to sulfuric acid at the natural pH of the droplets in most atmospheric aqueous systems.

K2 [Pd(NO3)4] has been prepared and its crystal structure determined by use of a CAD-4 diffractometer with monochromatic Mo Kα radiation. The space group is P21/c with Z = 4; a= 7.940(2); b = 15.469(4); c = 9.453(2) Å; β = 91.10(3)°. The refinement converged to R = 0.023. The structure contains discrete complexes of [Pd(NO3)4]2− with pseudo symmetry C4. Pd coordinates four oxygen from different unK2[Pd(NO3)4] has been prepared and its crystal structure determined by use of a CAD-4 diffractometer with monochromatic Mo Kα radiation.

The global methane (CH4) budget is becoming an increasingly important component for managing realistic pathways to mitigate climate change. This relevance, due to a shorter atmospheric lifetime and a stronger warming potential than carbon dioxide, is challenged by the still unexplained changes of atmospheric CH4 over the past decade. Emissions and concentrations of CH4 are continuing to increase,

The BRAHMS collaboration has measured transverse momentum spectra of pions, kaons, protons, and antiprotons at rapidities 0 and 3 for Cu+Cu collisions at sNN=200 GeV. As the collisions become more central the collective radial flow increases while the temperature of kinetic freeze-out decreases. The temperature is lower and the radial flow weaker at forward rapidity. Pion and kaon yields with tran

The professional profiles of the Auditors-General have gained scarce attention in scholarly work. Yet, these profiles may have major consequences for the choices that are made at the Supreme Audit Institution (SAI), for example in terms of audit approaches. This article builds on the case of the Swedish National Audit Office (SNAO). In Sweden, there is no public list of qualifications for the appo

Despite multiple attempts to infer the higher-level phylogenetic relationships of skipper butterflies (Family Hesperiidae), uncertainties in the deep clade relationships persist. The most recent phylogenetic analysis included fewer than 30% of known genera and data from three gene markers. Here we reconstruct the higher-level relationships with a rich sampling of ten nuclear and mitochondrial mark

Background: Eosinophils are innate immune cells present in the intestine during steady state conditions. An intestinal eosinophilia is a hallmark of many infections and an accumulation of eosinophils is also observed in the intestine during inflammatory disorders. Classically the function of eosinophils has been associated with tissue destruction, due to the release of cytotoxic granule contents.

The growing complexity of digital signal processing applications make a compelling case the use of high-level design and synthesis methodologies for the implementation on programmable logic devices and embedded processors. Past research has shown that, for complex systems, raising the level of abstraction of design stages does not necessarily come at a penalty in terms of performance or resource r

Action Plan B3 of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) focuses on the integrated care of chronic diseases. Area 5 (Care Pathways) was initiated using chronic respiratory diseases as a model. The chronic respiratory disease action plan includes (1) AIRWAYS integrated care pathways (ICPs), (2) the joint initiative between the Reference site MACVIA-LR (Contre

This case study of development in a technical university situates distributed leadership in higher education in an organizational perspective. Analysis of documentation from development programs and interviews with 10 faculty members showed that leadership practices were related to different institutional logics prominent in four key activities in this specific university: education, research, for

The changes in life-style with increased access of food and reduced physical activity have resulted in the global epidemic of obesity. Consequently, individuals with type 2 diabetes and cardiovascular disease have also escalated. A central organ in the development of diabetes is the pancreas, and more specifically the pancreatic beta cells within the islets of Langerhans. Beta cells have been assi
