Diergeneesmiddelen in aquacultuur

De Nederlandse visteelt heeft nog niet de beschikking over toegestane diergeneesmiddelen, terwijl de noodzaak om bepaalde middelen te gebruiken in de praktijk bestaat. Deze middelen zijn met name: flumequine, mebendazole, oxolinezuur, oxytetracycline, praziquantel en trimethosulfmix. Wat op dit moment niet duidelijk is is de farmacokinetiek van deze middelen voor de vissoorten die in Nederland gekweekt worden. Deze informatie is van belang om te voorkomen dat residuen van de geneesmiddelen in voor consumptie bestemde visproducten terecht komen. Om meer inzicht te krijgen in bestaande farmacokinetische data voor de meest gebruikte middelen is een literatuuronderzoek uitgevoerd

Environmental Levels and Trends of 1,2-dichloroethane, vinyl chloride and chloroform in water, sediment and biota for the European and Arctic regions: literature study

Data on concentrations of chloroform, 1,2-dichloroethane and vinyl chloride in European and Arctic waters, sediments and biota were collected from scientific literature and monitoring programmes for the period 1980–2005 and are presented in this report

Gebromeerde vlamvertrager gehaltes en DR-CALUX respons in sediment en zwevende stof van de Noordzeekustzone

In het kader van het RIKZ project ‘Lakmoes’ wordt de waterkwaliteit van de Waddenzee aan de hand van chemische parameters onderzocht. Omdat de ‘nieuwe milieuvervuilers’, de gebromeerde vlamvertragers al eerder zijn aangetoond in dit gebied [Zegers e.a. 2003], is het belangrijk om inzicht te krijgen in de verspreiding en gehaltes van deze verbindingen

Het bepalen van hexabroomcyclododecaan op tomaten (vruchten en planten)

De tomatenplanten van HBCD-trays bevatten twee keer zoveel HBCD als tomatenplanten van HBCD-vrije trays (resp. 2,0 en 2,6 ug/kg t.o.v. 1,2 en 0,9 ug/kg). In alle tomatenvruchtenmonsters waren de HBCD gehaltes zeer laag

Branching Fractions for D0 -> K+K- and D0 -> pi+pi-, and a Search for CP Violation in D0 Decays

Using the large hadroproduced charm sample collected in experiment E791 at Fermilab, we have measured ratios of branching fractions for the two-body singly-Cabibbo-suppressed charged decays of the D0: (D0 -> KK)/(D0 -> Kpi) = 0.109 +- 0.003 +- 0.003, (D0 -> pipi)/(D0 -> Kpi) = 0.040 +- 0.002 +- 0.003, and (D0 -> KK)/(D0 -> pipi) = 2.75 +- 0.15 +- 0.16. We have looked for differences in the decay rates of D0 and D0bar to the CP eigenstates K+K- and pi+pi-, and have measured the CP asymmetry parameters A_CP(K+K-) = -0.010 +- 0.049 +- 0.012 and A_CP(pi+pi-) = -0.049 +- 0.078 +- 0.030, both consistent with zero.Comment: 10 Postscript pages, including 2 figures.

The Williams Scale of Attitude toward Paganism: development and application among British Pagans

This article builds on the tradition of attitudinal measures of religiosity established by Leslie Francis and colleagues with the Francis Scale of Attitude toward Christianity (and reflected in the Sahin-Francis Scale of Attitude toward Islam, the Katz-Francis Scale of Attitude toward Judaism, and the Santosh-Francis Scale of Attitude toward Hinduism) by introducing a new measure to assess the attitudinal disposition of Pagans. A battery of items was completed by 75 members of a Pagan Summer Camp. These items were reduced to produce a 21-item scale that measured aspects of Paganism concerned with: the God/Goddess, worshipping, prayer, and coven. The scale recorded an alpha coefficient of 0.93. Construct validity of the Williams Scale of Attitude toward Paganism was demonstrated by the clear association with measures of participation in private rituals

Search for Rare and Forbidden Dilepton Decays of the D+, Ds, and D0 Charmed Mesons

We report the results of a search for flavor-changing neutral current, lepton-flavor violating, and lepton-number violating decays of D+, Ds, and D0 mesons (and their antiparticles) into modes containing muons and electrons. Using data from Fermilab charm hadroproduction experiment E791, we examine the pi,l,l and K,l,l decay modes of D+ and Ds and the l+l- decay modes of D0. No evidence for any of these decays is found. Therefore, we present branching-fraction upper limits at 90% confidence level for the 24 decay modes examined. Eight of these modes have no previously reported limits, and fourteen are reported with significant improvements over previously published results.Comment: 12 pages, 3 figures, LaTeX, elsart.cls, epsf.sty, amsmath.sty Submitted to Physics Letters
