Das factum "konzil" in rechshistorischer sicht
El Concilio ecumenzco se considera la expresiĂłn
del Episcopado universal. Por otra
parte, si se pregunta a qué responde la existencia
de este Ăłrgano del gobierno central,
la respuesta salta a la vista: a la colegialidad
episcopal. Cabe, sin embargo, esta pregunta:
¿puede el Concilio ecuménico asentarse
también -nunca sólo- sobre el principio
de participaciĂłn? En otras palabras:
¿puede abrirse el Concilio ecuménico no sólo
a los obispos (lĂnea de jerarquĂa) sino
también a representantes del pueblo cristiano
· como tal? El Prof. P[¥jchl analiza algunos
hechos histĂłricos que pueden servir

Water footprint analysis for the assessment of milk production in Brandenburg (Germany)
The working group "Adaptation to Climate Change" at the Leibniz-Institute for Agricultural Engineering Potsdam-Bornim (ATB) is introduced. This group calculates the water footprint for agricultural processes and farms, distinguished into green water footprint, blue water footprint, and dilution water footprint.
The green and blue water demand of a dairy farm plays a pivotal role in the regional water balance. Considering already existing and forthcoming climate change effects there is a need to determine the water cycle in the field and in housing for process chain optimisation for the adaptation to an expected increasing water scarcity. Resulting investments to boost water productivity and to improve water use efficiency in milk production are two pathways to adapt to climate change effects.
In this paper the calculation of blue water demand for dairy farming in Brandenburg (Germany) is presented. The water used for feeding, milk processing, and servicing of cows over the time period of ten years was assessed in our study. The preliminary results of the calculation of the direct blue water footprint shows a decreasing water demand in the dairy production from the year 1999 with 5.98Ă109 L/yr to a water demand of 5.00Ă109 L/yr in the year 2008 in Brandenburg because of decreasing animal numbers and an improved average milk yield per cow. Improved feeding practices and shifted breeding to greater-volume producing Holstein-Friesian cow allow the production of milk in a more water sustainable way. The mean blue water consumption for the production of 1 kg milk in the time period between 1999 to 2008 was 3.94±0.29 L.
The main part of the consumed water seems to stem from indirect used green water for the production of feed for the cows
EU Agro Biogas Project
EU-AGRO-BIOGAS is a European Biogas initiative to improve the yield of agricultural biogas plants in Europe, to optimise biogas technology and processes and to improve the efficiency in all parts of the production chain from feedstock to biogas utilisation. Leading European research institutions and universities are cooperating with key industry partners in order to work towards a sustainable Europe. Fourteen partners from eight European countries are involved. EU-AGRO-BIOGAS aims at the development and optimisation of the entire value chain â to range from the production of raw materials, the production and refining of biogas to the utilisation of heat and electricity
A co-registration investigation of inter-word spacing and parafoveal preview: Eye movements and fixation-related potentials
Participantsâ eye movements (EMs) and EEG signal were simultaneously recorded to examine foveal and parafoveal processing during sentence reading. All the words in the sentence were manipulated for inter-word spacing (intact spaces vs. spaces replaced by a random letter) and parafoveal preview (identical preview vs. random letter string preview). We observed disruption for unspaced text and invalid preview conditions in both EMs and fixation-related potentials (FRPs). Unspaced and invalid preview conditions received longer reading times than spaced and valid preview conditions. In addition, the FRP data showed that unspaced previews disrupted reading in earlier time windows of analysis, compared to string preview conditions. Moreover, the effect of parafoveal preview was greater for spaced relative to unspaced conditions, in both EMs and FRPs. These findings replicate well-established preview effects, provide novel insight into the neural correlates of reading with and without inter-word spacing and suggest that spatial selection precedes lexical processing
