Hoogeboom, P. (author), Koomen, P.J. (author), Snoeij, P. (author), Pouwels, H. (author)The PHARUS project (PHARUS stands for Phased Array Universal SAR) aims for a polarimetric C-band aircraft SAR that will be finalized in 1994. The system will make use of a phased array antenna with solid state amplifiers. The project consists of two phases, a definition phase and a realization phase. The definition phase was intended to increase...conference paper 1992

TNO-Institute of Animal Nutrition and Physiology (author), Schutte, J.B. (author), de Jong, J. (author), van Weerden, E.J. (author), van Baak, M.J. (author)1. Two experiments were conducted to examine the effect of feeding D-xylose and L-arabinose on broiler performance, body composition, caecal length and weight, and liver weight. 2. Graded amounts (25, 50 and 75 g/kg) of D-xylose or L-arabinose were added to either a practical type (Exp. A) or a semi-purified (Exp. B) basal diet. As reference, a...article 1992

(author), van der Mark, F. (author)The influence of environmental and cultural changes was investigated on both anther culture and microspore culture of barley cv. Igri. The highest regeneration frequency for both culture systems was obtained when at least 50% of the microspore population was in the mid-late to late uninucleate stage, when the anthers had been pretreated for 4...article 1992

As reference, D-glucose was included in the experiment. A second experiment was performed to determine the AMEn of D-xylose and L-arabinose. Results of Experiment 1 showed a significant...article 1990

Hoogeboom, P. (author), Koomen, P.J. (author), Otten, M.P.G. (author), Pouwels, H. (author), Snoeij, P. (author)A few years ago three institutes in the Netherlands developed a plan to design and build a polarimetric C-band aircraft SAR system of a novel design, called PHARUS (PHased Array Universal SAR), meant as a replacement for our current digital SLAR system. These institutes are the Physics and Electronics Laboratory TNO in The Hague (prime...conference paper 1989

The study consisted of a social survey and a noise measurement program. It appeared that tramway noise does not contribute to the annoyance of the total noise if tramway annoyance is substantially below road traffic annoyance (one or two points and more on a five-point...article 1988

Hoogeboom, P. (author)In The Netherlands a digltal SLAR system (X-band)is used since many years in the radar remote sensing research. This system supports research Programs in which also other equipment is used, for instance a multiband airborne scatterometer. Based on our experience in radar remote sensing a polarimetric C-band aircraft SAR is designed, to be...article 1988

The colony was built up from 1964 to 1971 by the acquisition of mostly young chimpanzees; thereafter, it was increased by local breeding. The ages at which the animals became reproductive were between 6 and 11 years for the males and between 7 and 15 years for...article 1983

Without water, no one can survive for more than a few days. This vital element covers about, three-quarters of the earth's surface. But 97.4 per cent is salt water in oceans; 1.8 percent is frozen in polar regions. Fresh water, needed by...report 1983
