Patent DE10 2004 037 519 B4 “Sensor Process and Device for Determining a Physical Value“. A Proof of Concept
(2010-06-11)
At present, a fraction of 0.1 - 0.2% of the patients undergoing surgery become aware during the process. The situation is referred to as anesthesia awareness and is obviously very traumatic for the person experiencing it. The reason for its occurrence is mostly an insufficient dosage of the narcotic Propofol combined with the incapability of the technology monitoring the depth of the patient’s anesthetic state to notice the patient becoming aware.
A solution can be a highly sensitive and selective real time monitoring ...

Master Plan for Renewable Energy based Electricity Generation in The Gambia
(2010-03-17)
The principal objective of this paper is to develop a methodology for the formulation of a master plan for renewable energy based electricity generation in The Gambia, Africa. Such a master plan aims to develop and promote renewable sources of energy as an alternative to conventional forms of energy for generating electricity in the country.
A tailor-made methodology for the preparation of a 20-year renewable energy master plan focussed on electricity generation is proposed in order to be followed and verified ...

The European organic food market - how to increase its transparency?
(2010-12-06)
Der Europäische Markt für ökologische Lebensmittel ist seit den 1990er Jahren stark gewachsen. Begünstigt wurde dies durch die Einführung der EU-Richtlinie 2092/91 zur Zertifizierung ökologischer Produkte und durch die Zahlung von Subventionen an umstellungswillige Landwirte. Diese Maßnahmen führten am Ende der 1990er Jahre für einige ökologische Produkte zu einem Überangebot auf europäischer Ebene. Die Verbrauchernachfrage stieg nicht in gleichem Maße wie das Angebot, und die Notwendigkeit für eine Verbesserung des ...

Veränderungen im Öko-Lebensmittelkonsum in Familien mit Kindern und deren Hintergründe
(2010-02-17)
Im Rahmen der Arbeit wird den Fragen nachgegangen, inwiefern der Konsum von Öko-Lebensmitteln in Familien mit Kindern im zeitlichen Verlauf Veränderungen unterliegt und worin Veränderungen im Öko-Lebensmittelkonsum in Familien mit Kindern begründet sind. Aus den hierzu gewonnenen Erkenntnissen werden Schlussfolgerungen für die Konsumentenforschung und das Marketing von Öko-Produkten gezogen. Theoretische Grundlage stellen der Familienzyklus sowie Forschungsergebnisse zum Konsumentenverhalten in Familien und zum Konsum ...

Shifting cultivation and forest resources in Nagaland, N.-E. India
(2010-06-17)
Die vorliegende Studie befasst sich mit der Ressourcennachhaltigkeit der traditionellen, auf Wanderfeldbau beruhenden Subsistenzwirtschaft in zwei Dörfern (Hongphoy und Minyakshu) in Nagaland im Nordosten Indiens. Hierbei werden die Cerealien Produktion, der Feuerholz Konsum und auch die Folgen der intensivierten Bewirtschaftung (Forstdegradation und Bodenverarmung) im Hinblick auf das Bevölkerungswachstum diskutiert. Während das traditionelle System des Wanderfeldbaus (Jhum) seit Jahrzehnten die Bedürfnisse der ...

On CD-systems of stateless deterministic R-automata with window size one
(2010-04-27)
We study cooperating distributed systems (CD-systems) of restarting automata that are very restricted: they are deterministic, they cannot rewrite, but only delete symbols, they restart immediately after performing a delete operation, they are stateless, and they have a read/write window of size 1 only, that is, these are stateless deterministic R(1)-automata. We study the expressive power of these systems by relating the class of languages that they accept by mode =1 computations to other well-studied language ...

Pharmaceutical consumption and residuals potentially relevant to nutrient cycling in Greater Accra, Ghana
(Kassel University Press, 2010)
Recycling nutrients form sanitary wastes back into agricultural ecosystems offers an option to alleviate soil depletion in regions where the use of mineral fertiliser is limited. Exemplary nutrient and water cycling approaches, including collection, treatment and use of human urine, are established at Valley View University (VVU) in Greater Accra, Ghana.
Concerns have been recently raised in regard to fate and impact of pharmaceutical residues in soils and interlinked environment. To evaluate in how far emerging ...

Learning achievements of farmers during the transition to market-oriented organic agriculture in rural Uganda
(Kassel University Press, 2010)
Organic agriculture requires farmers with the ability to develop profitable agro-enterprises on their own. By drawing on four years of experiences with the Enabling Rural Innovation approach in Uganda, we outline how smallholder farmers transition to organic agriculture and, at the same time, increase their entrepreneurial skills and competences through learning. In order to document this learning we operationalised the Kirkpatrick learning evaluation model, which subsequently informed the collection of qualitative ...

Smallholder group certification in Uganda - Analysis of internal control systems in two organic export companies
(Kassel University Press, 2010)
The organic agricultural sector of Uganda is among the most developed in Africa in terms of its professional institutional network and high growth rates of number of certified farmers and land area. Smallholder farmers are certified organic through contract production for export companies using a group certification scheme (internal control system - ICS). The ICS is a viable and well-accepted tool to certify small-scale producers in developing countries all over the world. Difficulties in certification are still ...
