An exact treatment of the van der Waals interaction between two spherical dielectric bodies possessing purely classical degrees of freedom is presented. The spheres are described by multipole expansions of their fluctuating charge distributions, and the correlation between the fluctuations are taken into account using classical electrostatics and statistical mechanics. The presented approach avoid

The European Position Paper on Rhinosinusitis and Nasal Polyps 2012 is the update of similar evidence based position papers published in 2005 and 2007. The document contains chapters on definitions and classification, we now also propose definitions for 'difficult to treat' rhinosinusitis, control of disease and better definitions for rhinosinusitis in children. More emphasis is placed on the diag

Studies of the spin and parity quantum numbers of the Higgs boson are presented, based on protonproton collision data collected by the ATLAS experiment at the LHC. The Standard Model spin-parity J(P) = 0(+) hypothesis is compared with alternative hypotheses using the Higgs boson decays H -> gamma gamma, H -> ZZ* -> 4l and H -> WW* -> l nu l nu, as well as the combination of these channels. The ana

The MAX IV pro-injector will have one thermionic and one photocathode S-band RF gun, where the former will be used for ring injections. During ring injections, the bunches leaving the pre-injector have a structure that consists of ten 10 ns bunch trains, each containing three bunches. A chopper system consisting of two striplines and an adjustable aperture is used, where the desired bunch structur

Bör filmarkiv främst tillvarata eller förevisa sina samlingar? Noggrant bevara och katalogisera eller visa och sprida dem? Henri Langlois, grundaren av Cinémathèque Français menade att om film aldrig visas, utan endast förvaras i metallburkar, kommer den att sluta som skosmörja. Den digitala utvecklingen förefaller givit honom rätt; bred tillgänglighet till filmens historia är allra viktigast på e

The binuclear title complex, [Zn2(C33H33N6O)(CH3COO2)(CH3OH)](ClO4)2, was synthesized by the reaction between 2,6-bis-({[bis-(pyridin-2-yl)meth-yl]amino}-meth-yl)-4-methyl-phenol (H-BPMP), Zn(OAc)2 and NaClO4. The two Zn(II) ions are bridged by the phenolate O atom of the octadentate ligand and the acetate group. An additional methanol ligand is terminally coordinated to one of the Zn(II) ions, re

By the end of 2020, all EU member states need to ensure that all newly constructed buildings consume ` nearly zero' energy and that their energy needs are produced locally as much as possible and with renewable sources; a concept called nearly Zero Energy Buildings (ZEB). At the same time, more and more people live in cities, where the access to local renewable energy sources -wind and solar-is li

The effects of color reconnection (CR) at e(+) e(-) colliders are revisited, with focus on recently developed CR models. The new models are compared with the LEP2 measurements for e(+) e(-) -> W+W- -> q(1)(q) over bar (2)q(3)(q) over bar4 and found to lie within their limits. Prospects for constraints from new high- luminosity e(+) e(-) colliders are discussed. The novel arena of CR in Higgs decay

This paper describes an analysis of the angular distribution of W -> e nu and W -> mu nu decays, using data from pp collisions at root s = 7 TeV recorded with the ATLAS detector at the LHC in 2010, corresponding to an integrated luminosity of about 35 pb(-1). Using the decay lepton transverse momentum and the missing transverse momentum, the W decay angular distribution projected onto the transver

Two new solvates were prepared in the system Cu(I) I using a solvolysis reaction. The structures for both of them were solved by X-ray crystallography, showing that they constitute two modifications of the same compound with the net formula [Cu4I6](P(C6H5)(4))(2)center dot 2OC(CH3)(2). Both types of crystals show vivid fluorescence when exposed to UV light. The formation of the first modification

In the large majority of product development projects, computer-based design analyses are performed to assess the feasibility of potential technical solutions. As a first step to bring about a deeper understanding of the interactions between the engineering design and the design analysis activities, a survey has been performed in industry. The results of the survey cover: the use of design analysi

Popular Abstract in Swedish Bränslecellen uppfanns redan 1838, det kommersiella genombrottet dröjde till 2007, den framtida potentialen är mycket lovande Domedagsprofetior angående växthuseffektens betydelse för livet på jorden når oss via media allt oftare. Bränsleceller är mycket lovande för ett framtida miljövänligt samhälle. Hög energieffektivitet och inga utsläpp av koldioxid, kväveoxider elFuel cells are electrochemical devices that directly transform chemical energy into electricity. They are promising for future energy systems, since they are energy efficient, able to use renewable fuels and, when hydrogen is used as fuel, there are no direct emissions of greenhouse gases. Various improvements are made during the recent years, however the technology is still in the early phases of

During the Mesoproterozoic, central Fennoscandia and Laurentia (Greenland) were characterized by a weakly extensional stress regime, as evident from episodic rapakivi granites, dolerite dykes, continental rift intrusives, sandstone basins and continental flood basalts. Along the southwestern active margin of Fennoscandia, the 1.64-1.52 Ga Gothian and 1.52-1.48 Ga Tele-markian accretionary events r

Chronic inflammation and oxidative stress might be considered the key mechanisms of aging. Insulin resistance (IR) is a phenomenon related to inflammatory and oxidative stress. We tested the hypothesis that IR may be associated with cellular senescence, as measured by leukocyte telomere length (LTL), and arterial stiffness (core feature of arterial aging), as measured by carotid-femoral pulse wave

This review covers automatic control of continuous aeration systems in municipal wastewater treatment plants. The review focuses on published research in the 21st century and describes research into various methods to decide and control the dissolved oxygen (DO) concentration and to control the aerobic volume with special focus on plants with nitrogen removal. Important aspects of control system i

Mapping coastal inlets and their catchment areas is essential for management of the coastal zone. The coastal inlets are important channels of exchange of nutrients, water and sediment between the land and sea. They are also important elements of the coastal hydrological system and play a vital role in controlling the water flow into the sea during floods. Blocking of the coastal inlets is one of

This paper explores how regulatory relationships in the global audit arena are being affected by the current financial crisis. Key policy initiatives and debates are analyzed, along with Institutional interactions, in particular between the International Federation of Accountants (IFAC), international regulators and the large audit firms. The events are placed in the context of the new internation

A major barrier for cancer immunotherapy is the presence of suppressive cell populations in patients with cancer, such as myeloid-derived suppressor cells (MDSC) and tumor-associated macrophages (TAM), which contribute to the immunosuppressive microenvironment that promotes tumor growth and metastasis. Tasquinimod is a novel antitumor agent that is currently at an advanced stage of clinical develo
