With an increasing demand on load flexibility in power supply networks, advanced control systems for plants with carbon capture units gain in significance. Minimizing the energy demand for carbon dioxide removal under these circumstances is a major task of such a control strategy. In this work a dynamic model in Modelica of a chemical absorption process run with an aqueous monoethanolamine (MEA) i

The Hollow Rock Shelter site in Western Cape Province, South Africa, was excavated in 1993 and 2008. This study presents new results from a technological analysis of Still Bay points and bifacial flakes from the site. The results show that Still Bay points from the site are standardized tools. The points in the assemblage consist of a complex mixture of whole and fragmented points in all phases of

Vehicle-to-Vehicle (V2V) communication is a challenging but fast growing technology that has potential to enhance traffic safety and efficiency. It can also provide environmental benefits in terms of reduced fuel consumption. The effectiveness and reliability of these applications highly depends on the quality of the V2V communication link, which rely upon the properties of the propagation channel

Riternas förändring i det moderna Sverige inleder ett temanummer i Svensk Teologisk Kvartalskrift där olika forskare vill diskutera hur olika religiösa traditioner genomgår rituell förändring på grund av migration, sekularisering och modernitet i dagens Sverige.

We present multi-epoch high-resolution optical spectroscopy, UV/radio/X-ray imaging, and archival Hubble and Spitzer observations of an intermediate luminosity optical transient recently discovered in the nearby galaxy NGC 300. We find that the transient (NGC 300 OT2008-1) has a peak absolute magnitude of M-bol approximate to -11.8 mag, intermediate between novae and supernovae, and similar to the

The article focuses on lifestyle entrepreneurship, characterised by a balancing work between personal lifestyle motives and economic motives. It builds on a qualitative study of business owners who have realized a life dream of starting a countryside business in the tourism and hospitality industry in Sweden. Through the notion of "balancing work", the analysis focuses on the tension between a per

An algorithm to compute the radiation center of an antenna, using the Spherical wave expansion (SWE) of the far field or the far field directly, is introduced. The method is based on the angular momentum that is uniquely defined for any antenna far field pattern. The radiation center is defined as the phase reference point where the angular momentum is minimized and corresponds to minimizing the p

Despite its long history, the Theory of Characteristic Modes has only been utilized in antenna design for perfect electric conductors. This is due to computational problems associated with dielectrics and magnetic materials. In particular, the symmetric form of the PMCHWT surface formulation for the Method of Moments (MoM) solves for both external (real) and internal (non-real) resonances of a str

Background: Vitamin D is hypothesized to lower the risk of breast cancer by inhibiting cell proliferation via the nuclear vitamin D receptor (VDR). Two common single nucleotide polymorphisms (SNP) in the VDR gene (VDR), rs154441.0 (BsmI), and rs2228570 (FokI), have been inconsistently associated with breast cancer risk. Increased risk has been reported for the FokIff genotype, which encodes a less

Background: Unambiguous interpretation of ordered rating scale response categories requires distinct meanings of category labels. Also, summation of item responses into total scores assumes equal intervals between categories. While studies have identified problems with rating scale response category functioning there is a paucity of empirical studies regarding how respondents interpret response ca

The reactivity of the sigma,pi-furyl complex [Fe-2(CO)(6)(mu-Fu)(mu-PFu(2))] (1) towards PPh3 and a range of bidentate phosphines has been studied and a number of different reaction products have been identified. With PPh3, carbonyl substitution affords [Fe-2(CO)(5)(PPh3)(mu-Fu)(mu-PFu(2))] (2) in which the new phosphine is coordinated to the iron center that is sigma-coordinated by the bridging f

It is suggested that cultivars of wheat (Triticum aestivum L.) with regulated growth and development would be able to produce higher yields under water-limited conditions, which is crucial in future food production. Water use efficiency (WUE) is worthy of exploration in this regard. In this study, the effects of nitrogen fertilizer levels (0, 40 and 80 kg Nha(-1)) and a plant growth retardant (Chl

Aim. The aim of this paper was to evaluate short-term outcome of the use of endoanchors to secure the primary migrated endograft and additional extender cuffs to the aortic wall in patients with previous failed endovascular aortic aneurysm repair. Methods. Consecutive patients who needed proximal repair of a primary failed endograft due to migration (with or without type IA endoleaks) were treated

A search is reported for Higgs boson decay to mu(+)mu(-) using data with an integrated luminosity of 24.8 fb(-1) collected with the ATLAS detector in pp collisions at root s = 7 and 8 TeV at the CERN Large Hadron Collider. The observed dimuon invariant mass distribution is consistent with the Standard Model background-only hypothesis in the 120-150 GeV search range. For a Higgs boson with a mass o
