On 10 September 1751 the Swedish botanist Pehr Osbeck visited the outskirts of Canton. On his way back into the city he was surrounded by a gang of robbers who demanded money from him. When they did not receive any money, they pelted Osbeck with large stones; it was very fortunate that he was not severely injured. One of the questions this paper discusses is what were the laws in China at that tim

Inverted pendulums are very well suited to investigate friction phenomena and friction compensation because the effects of friction are so clearly noticeable. This paper analyses the effect of friction on the Furuta pendulum. It is shown that friction in the arm drive may cause limit cycles. The limit cycles are well predicted by common friction models. It is also shown that the amplitudes of the

In an attempt to shed light on the role of the polyamines, putrescine, spermidine, and spermine in cell cycle progression, polyamine biosynthesis has been analyzed during the cell cycle of Chinese hamster ovary cells, and cell cycle kinetics have been investigated in cells treated with polyamine biosynthesis inhibitors. Cells were synchronized with the mitotic detachment technique, and at various

A new disturbance signal was introduced for the paper machine drying section and its feedforward control was evaluated. Control of the moisture content is conventionally accomplished by adjusting the steam pressure in the cylinders. By adding feedforward to a previously presented mid-ranging control system, the moisture disturbances rejection could be significantly improved.

Popular Abstract in Swedish Andra kapitlet redogör för konsekvenserna av att anta att inte bara huvuden utan också fraser är sonder. Slutsatsen är att det inte finns varken teoretisk eller empirisk anledning att behålla stipulationen att endast huvuden är sonder. I tredje kapitlet redogörs för de strukturella skillnaderna mellan pronomen och reflexiver. Skillnaden är att pronomen och refererande uIn chapter 2, I claim that not only heads, but phrases, too, are probes. I show that there are in fact no theoretical and empirical problems involved if we abandon the stipulation that only heads may probe. In chapter 3, I explore the structure of nominal expressions. The difference we see between reflexives and personal pronouns is argued to be an effect of the syntactic derivation, not of the p

Objective(s): Colombia has the third largest black population in the Americas after Brazil and the USA. In 2005 mortality rate under 5 in Colombia was 21.5 per 1000, with a reduction of 82 per cent between 2005 and 1960. That rate is not in line with rates for Cuba (6.8), Chile (9.1) or Costa Rica (10.4). Here we aim to provide evidence that a further reduction of child mortality relates to the un
