February 22, 1756, exactly 250 years ago, died one of Linnaeus’ apostles, the Swede Pehr Löfling, at the missions of San Antonio de Caroní, Venezuela. He was buried under an orange tree, just 27 years old. Sent by Linnaeus to participate in a Spanish border expedition, led by José de Iturriaga, he had the task to explore the flora and fauna of the New World. After spending more than two years in S
In the present work we study the 1s2s2p3 6S(o) --> 1s2s2p(2)3s6P(e) and 1s2s2p3 6S(o) --> 1s2s2p(2)3d6P(e) transitions energies and probabilities in the boron isoelectronic sequence, including B I, C II, N III, O IV, F V, Mg IX and Al IX. Extending the calculations to Be-, we also confirm the bound character of the excited 1s2s2p3 6S(o) state and predict the electron affinity EA = 1.29783eV for Be
Informed product choices are,a prerequisite for the greening of consumption. Nordic consumers are subject to an ever-growing amount of product-related environmental information that is available in a number of formats. The degree to which they use information is disputed. This paper reviews Nordic research on consumer perceptions, understanding and use of product-related environmental information.
The most economical way to convert truck and bus DI-diesel engines to natural gas operation is to replace the injector with a spark plug and modify the combustion chamber in the piston crown for spark ignition operation. The modification of the piston crown should give a geometry well suited for spark ignition operation with the original swirling inlet port. Ten different geometries were tried on
The expression and activities of constitutive nitric oxide synthase (cNOS) and inducible nitric oxide synthase (iNOS) in relation to insulin and glucagon secretory mechanisms were investigated in islets isolated from rats subjected to total parenteral nutrition (TPN) for 10 d. TPN is known to result in significantly increased levels of plasma lipids during the infusion time. In comparison with isl
Popular Abstract in Swedish Kvinnor mot krig. Aktioner och nätverk för fred 1914-1940. Syftet med avhandlingen är att undersöka varför och på vilket sätt kvinnor skapade fredsaktioner under första världskriget och mellankrigstiden. Jag har studerat hur kvinnor mobiliserades, hur aktionerna genomfördes, vilket motstånd som väcktes och vad som hände efteråt. Utgångspunkten är kollektiva aktioner, soThe aim of this dissertation is to investigate how and why women established peace actions during World War I and the period between the wars. I have examined how women were mobilized, how the actions were carried out, what kind of opposition was awakened, and what happened afterwards. My startingpoint is collective actions based on individual standpoints and temporary mobilizations. Organizations
A 20-l packed-bed reactor filled with foamed glass beads was tested for the treatment of acetonitrile HPLC wastes. Aeration was provided by recirculating a portion of the reactor liquid phase through an aeration tank, where the dissolved oxygen concentration was kept at 6 mg/l. At a feeding rate of 0.77 g acetonitrile l–1 reactor day–1, 99% of the acetonitrile was removed; and 86% of the nitrogen
The angle dependence of the scattered light from pairs and one-dimensional arrays of nanowires was studied. The intensity of the scattered light varied distinctly during rotation of the structure. The results could be theoretically modeled by treating a pair of nanowires as a double slit and an array of nanowires as a grating. The correspondence between theory and experimental results conclusively
The Photosystem II multisubunit protein complex can be extracted from thylakoid membranes with non-ionic detergents and subjected to various spectroscopical and biochemical investigations. This paper shows that after extraction with dodecyl-beta-D-maltoside, several Photosystem II complexes could be resolved by isoelectric focusing. Structurally, the various Photosystem II complexes differed from
We report measurements with the quartz crystal microbalance with dissipation monitoring (QCM-D) technique, with focus on how the shear oscillation amplitude of the sensor surface influences biorecognition binding events. Technically, this is made as reported recently ( M. Edvardsson, M. Rodahl, B. Kasemo, F. Hook, Anal. Chem., 2005, 77( 15), 4918-4926) by operating the QCM in dual frequency mode;
The aim of the present study was to evaluate the effects on muscle stretchability, joint flexibility, muscle strength and endurance in construction workers of a 3-month period of a 10-min morning warming-up exercise (MWU), performed at the building site every working day. Thirty construction workers participated in the program. Seventeen construction workers at other building sites served as contr
In this article, different approaches to the field of urban ecology are distinguished. The focus lies on the approach characterized by looking at the city as an ecological system, since this view has given rise to the most fruitful discussion from a social geographical perspective. Further, references are made to four studies of applied urban ecology with short summaries of the most important conc
The polyamines putrescine, spermidine, and spermine are organic cations that are required for cell growth and differentiation. Ornithine decarboxylase (ODC), the first and rate-limiting enzyme in the polyamine biosynthetic pathway, catalyzes the conversion of ornithine to putrescine. As the polyamine biosynthetic pathway is essential for the growth and survival of Leishmania donovani, the causativ
