A third order conservative reconstruction, in the context of finite volume schemes for hyperbolic conservation laws, is constructed based on logarithmic functions. This logarithmic method reconstructs without the use of a limiter, any preprocessing of input data, special treatments for local extrema, or shock solutions. Also the method is local in the sense that data from only the nearest neighbor

Fluence-response relationships for the enhancement of ultraweak luminescence by UV radiation were determined in leaves of Brassica napus L. (cv. Ceres) when either the adaxial or abaxial leaf surface was exposed to monochromatic radiation (270–340 nm). Action spectra for both leaf surfaces were constructed from the fluence-response curves at the fluence required to obtain a doubling of the ultrawe

Transient-state kinetic experiments and analyses have been performed to examine the validity of hitherto unchallenged evidence proposed to be indicative of a channelled transfer of triose phosphates from aldolase to glyceraldehyde-3-phosphate dehydrogenase and glycerol-3-phosphate dehydrogenase. The results lend no support to such proposals, but show that the kinetic behaviour of the examined aldo

The homogenization of the Maxwell equations at fixed frequency is addressed in this paper. The bulk (homogenized) electric and magnetic properties of a material with a periodic microstructure are found from the solution of a local problem on the unit cell by suitable averages. The material can be anisotropic and satisfies a coercivity condition. The exciting field is generated by an incident field

Several principal aspects and components of an advanced catalytic exhaust after-treatment system for NO, reduction on a heavy-duty diesel truck engine have been systematically examined and evaluated. The after-treatment system consists of de-NO, catalysts, injection of a reducing agent (diesel fuel), and computer programs to model the engine and catalysts in real time. These models are combined wi

Hemicraniectomy in patients with malignant middle cerebral artery (mMCA) infarct may be life-saving. The long-term prognosis is unknown. Patients with mMCA infarct treated with hemicraniectomy between 1998 and 2002 at three hospitals were included. The criterion for surgical intervention was if the patients deteriorated from awake to being responding to painful stimuli only. All patients were foll

Several recent international publications (e.g. Platzack 1996, 2001; Håkansson, Pienemann & Sayehli 2002; Pienemann 1998; Pienemann & Håkansson 1999) have claimed that learners take the same developmental route in the acquisition of syntax of a second or foreign language, irrespective of their first language (L1). Targetlike verb placement in a Germanic V2 language like German, Dutch or Sw

Popular Abstract in Swedish Den rättighetslagstiftning som presenterades i handikapputredningens slutbetänkande (SOU 1991:46), Lagen om stöd och service till vissa funktionshindrade, LSS, visade att samhällets välfärd i ett etiskt perspektiv är något som angår alla. Kravet på samhällssolidaritet innebär enligt utredningen att samhällets insatser måste utformas i enlighet med kvalitetskrav som syftThe legislation on rights that was presented in the final report of the commission of inquiry into handicap (SOU 1991:46), the Act concerning Support and Service for Persons with Certain Functional Impairments, showed that, from an ethical point of view, society´s welfare is something that concerns everyone. The demand for social solidarity, according to the inquiry, meant that public measures mus
