Abstract:

The short-term impacts of atrazine (herbicide), tributyltin (organometal) and copper on the behaviour of Euglena gracilis Klebs (Euglenophyta) were assessed. First, the ECOTOX automated image analysis system was used, which measured swimming velocity, cell shape, percentage of cells swimming upwards, and randomness of swimming. Next, visual observation by microscopy was used to measure percentage of cell motility and cell shape. Behavioural changes can be used as an indicator of stress in less than 24 h, potentially making them suitable for inclusion in early-warning systems for water quality.

Abstract:

To assess reprotoxicity of pesticides and other xenobiotics, rodents are often used with natural mating and litter size as end-points. However, because a male mouse can produce normal-size litters even with >50% reduced sperm count (Ecotox. Env. Saf. 73, 1092), this model could approve some chemical substances despite their reprotoxic effect. Thus, we aimed to establish a mouse IVF system to evaluate reprotoxicity of xenobiotics, illustrated by 2 pesticides [vinclozolin (vin), chlormequat (ccc)]. Experimental mice were given 2 pesticide doses by mixing into the feed: low (L) or high (H), eq

Abstract:

DairyMod and EcoMod, which are biophysical pasture-simulation models for Australian and New Zealand grazing systems, are described. Each model has a common underlying biophysical structure, with the main differences being in their available management options. The third model in this group is the SGS Pasture Model, which has been previously described, and these models are referred to collectively as ‘the model’. The model includes modules for pasture growth and utilisation by grazing animals, water and nutrient dynamics, animal physiology and production and a range of options for pasture manag

Abstract:

The National Model United Nations claims to be the most realistic simulation of the United Nations in the world. Every year more than 2500 students participate in the NMUN in New York, which partly takes place inside the original UNbuildings. For five days, the students simulate the different bodies of the UN-framework (e.g. Security Council, General Assembly, ECOSOC) by using the original UN-Rules of procedure and negotiating to formulate and pass resolutions on various topics.

Abstract. An Aerosol Time-Of-Flight Mass Spectrometer (ATOFMS) was deployed to investigate the size-resolved chemical composition of single particles at an urban background site in Paris, France, as part of the MEGAPOLI winter campaign in January/February 2010. ATOFMS particle counts were scaled to match coincident Twin Differential Mobility Particle Sizer (TDMPS) data in order to generate hourly size-resolved mass concentrations for the single particle classes observed. The total scaled ATOFMS particle mass concentration in the size range 150–1067 nm was found to agree very well with the sum

Abstract:

This is a Liberian perspective on the unique initiative by the Economic Community of West African States (ECOWAS) to resolve the Liberian conflict by organizing and deploying a Peace Monitoring Group in Liberia. It considers whether ECOWAS’ initiative can become a self-reliant security system that can end a civil war and institutionalize deterrence to subregional inter-state and internal conflicts. Can this self-generated, West African initiative set the stage for democratization? Is the initiative the start of an inter-African cooperative security system? Is the model of Nigerian leadership a
