OBJECTIVE To evaluate the effect of humidification on the odour, acceptability, and stuffiness of indoor air. METHODS In a six period cross over trial at the Pasila Office Center, Helsinki, the air of two wings of the building in turn were ventilated with air of 30%-40% humidity. A third wing served as a non-humidified control area. The quality of indoor air was assessed weekly by a panel con...

Norms, primarily of theoretical interest, of the successive overrelaxation method, with a relaxation parameter other than the optimum one, are studied. New results on this subject are presented and compared with those of Wachspress [8].

Several authors have treated kinetic effects associated with the ion-acoustic soliton; e.g., Ott and Sudan investigated linear electron Landau damping and Karpman and Lotko have looked at damping due to ion reflection. Here an O'Neil-type frozen wave calculation that includes effects associated with electron orbits in a soliton is presented. This calculation differs from previous ones in that t...

Step-asynchronous successive overrelaxation updates the values contained in a single vector using the usual Gauß–Seidel-like weighted rule, but arbitrarily mixing old and new values, the only constraint being temporal coherence— you cannot use a value before it has been computed. We show that given a nonnegative real matrix A, a σ ≥ ρ(A) and a vector w > 0 such that Aw ≤ σw, every iteration of ...

The public archives containing protein information in the form of NMR chemical shift data at the BioMagResBank (BMRB) and of 3D structure coordinates at the Protein Data Bank are continuously expanding. The quality of the data contained in these archives, however, varies. The main issue for chemical shift values is that they are determined relative to a reference frequency. When this reference ...

Technological progress has led to electronic exchanges attracting a major part of transaction volume for standardized stocks. In the field of derivatives and bonds, electronic exchanges failed to prosper and so called over-the-counter (OTC) trading is predominant: possibly because multi-attribute assets are hard to trade in structured two-sided markets. The present paper aims at alleviating thi...

As the chapters in this volume demonstrate, like other nascent medical technologies ovarian tissue cryopreservation (OTC) raises no earth-shatteringly new moral questions. Rather, it poses old moral questions in new ways, thus shedding light not only on our old answers but also on our old methods of reaching them. My task here is to point out the ways in which OTC forces us to embrace important...

Physical layer features of Ethernet from the first realization towards the 100 Gb Ethernet (100 GbE) development have been considered. Comparisons of these features are made according to the standardized data rates. Feasible physical layer options are then discussed for high data rates.

In order to satisfy the increasing demand of wireless broadband multimedia services, much attention has been paid to the 60 GHz band where as much as 5 GHz of spectrum has been reserved. However, in the indoor environment, the propagation of signals at this millimeter wave band is strongly hindered by walls, people and their movement, furniture, etc. As a result, a mobile user might experience ...

Methods The junior physicians on call interviewed all patients admitted to the medical admission unit at Sydvestjysk Sygehus in Esbjerg on the use of OTC-drugs, using a modified chart template designed for the purpose. All adult patients aged 15 and older admitted over a two week period in August 2012 were included. The patients were asked about the drugs taken, dosage, indication and effect. O...
