Kennis: van vastleggen naar laten stromen : aanbevelingen voor Lerende netwerken voor natuurbeheerders vanuit Gestalt, Kolb en Immediate-delayed compensation

Doel van het rapport is aanbevelingen te doen om kennisdoorstroming tussen terreinbeheerders onderling en met hun omgeving te verbeteren. Kennisdoorstroming gaat grotendeels onbewust, maar het is wel bewust te faciliteren door aandacht te geven aan drie onderdelen: 1. vastleggen van kennis, 2. tijd en plaats van de bijeenkomsten, 3. openheid om te gaan leren. Bij de laatste is de meeste winst te boeken en deze is te stimuleren door: Het wiel zelf mogen uitvinden om tot kennisontwikkeling te komen (Kolb). Mensen bewust maken van de omgeving waarin ze zich bewegen, waardoor ze voor hun kennisontwikkeling beter gebruik gaan maken van hun omgeving (Gestalt). Mensen vaak en met regelmaat de terugkoppeling geven dat ze dichter bij hun doel komen (Immediate-delayed compensation)

Detection of the tulip breaking virus (TBV) in tulips using optical sensors

The tulip breaking virus (TBV) causes severe economic losses for countries that export tulips such as the Netherlands. Infected plants have to be removed from the field as soon as possible. There is an urgent need for a rapid and objective method of screening. In this study, four proximal optical sensing techniques for the detection of TBV in tulip plants were evaluated and compared with a visual assessment by crop experts as well as with an ELISA (enzyme immunoassay) analysis of the same plants. The optical sensor techniques used were an RGB color camera, a spectrophotometer measuring from 350 to 2500 nm, a spectral imaging camera covering a spectral range from 400 to 900 nm and a chlorophyll fluorescence imaging system that measures the photosynthetic activity. Linear discriminant classification was used to compare the results of these optical techniques and the visual assessment with the ELISA score. The spectral imaging system was the best optical technique and its error was only slightly larger than the visual assessment error. The experimental results appear to be promising, and they have led to further research to develop an autonomous robot for the detection and removal of diseased tulip plants in the open field. The application of this robot system will reduce the amount of insecticides and the considerable pressure on labor for selecting diseased plants by the crop expert. © 2010 The Author(s

Catalysis by alkali and alkaline-earth metal ions in nucleophilic attack of methoxide ion on crown ethers bearing an intra-annular acetoxy group

Rates of reaction of methoxide ion with crown ethers bearing an intra-annular acetoxy group are markedly enhanced by alkali and alkaline-earth metal bromides as a result of much stronger interactions of the metal ions with transition states than with reactants.\ud \ud Rates of reactions of methoxide ion with crown ethers bearing an intra-annular acetoxy group markedly enhanced by alkali and alkaline-earth metal bromides as a result of much stronger interactions of the metal ion with transition state than with reactants

On the use of Kodak CR film for quality assurance of needle loading in I-125 seed prostate brachytherapy

Copyright © 2007 ACPSEM. All rights reserved.The document attached has been archived with permission from the publisher.Low dose rate brachytherapy using implanted I-125 seeds as a monotherapy for prostate cancer is now in use in many hospitals. In contrast to fractionated brachytherapy treatments, where the effect of incorrect positioning of the source in one treatment raction can be diminished by correcting the position in subsequent fractions, the I-125 seed implant is permanent, making correct positioning of the seeds in the prostate essential. The seeds are inserted into the prostate using needles. Correct configuration of seeds in the needles is essential in order to deliver the planned treatment. A comparison of an autoradiograph obtained by exposing film to the seed-loaded needles with the patient treatment plan is a valuable quality assurance tool. However, the time required to sufficiently expose Kodak XOMAT V film, currently used in this department is significant. This technical note presents the use of Kodak CR film for acquisition of the radiograph. The digital radiograph can be acquired significantly faster, has superior signal-to-noise ratio and contrast and has the usual benefits of digital film, e.g. a processing time which is shorter than that required for non-digital film, the possibility of image manipulation, possibility of paper printing and electronic storage.Lotte S.
