Pesticide-handling practices of smallholder coffee farmers in Eastern Jamaica
(Kassel University Press, 2013)
Pesticide use among smallholder coffee producers in Jamaica has been associated with significant occupational health effects. Research on pesticide handling practices, however, has been scarce, especially in eastern Jamaica. This explorative study aims at filling this gap and provides a first basis to develop effective interventions to promote a safer pesticide use. A random sample of 81 coffee farmers was surveyed. The majority of farmers reported to suffer from at least one health symptom associated with pesticide ...

Cassava root peel as a replacement for maize in diets for growing pigs: effects on energy and nutrient digestibility, performance and carcass characteristics
(Kassel University Press, 2013)
Two experiments were conducted to evaluate cassava root peel (CRP) as diet component for fattening pigs. In the first experiment, ten male pigs were used to investigate the nutrient digestibility and the nutritive value of CRP as replacement for maize in the diet at 0 %, 30 %, 40 %, 50 % and 60 %, while supplementing free amino acids (fAA). During two experimental periods, faeces were quantitatively collected and analysed for chemical composition. In the second experiment, 40 pigs received the same diets as in ...

Spatial and harvesting influence on growth, yield, quality and economic potential of Kalmegh (Andrographis paniculata Wall Ex. Nees)
(Kassel University Press, 2013)
Andrographis paniculata, commonly known as Kalmegh, is used both in Ayurvedic and Unani system of medicines because of its immunological, antibacterial and hepatoprotective properties. This study was carried out to investigate the influence of four harvesting times (120,135,150 days after planting and at seed maturity) and four planting distances (30×15, 30×10, 20×15 and 20×10 cm) on growth, dry herbage biomass, seed yield and quality traits of Andrographis paniculata at CCS Haryana Agricultural University, Hisar, ...

Determination of the silvo-melliferous regions of Benin: a nationwide categorisation of the land based on melliferous plants suitable for timber production
(Kassel University Press, 2015-10-07)
Perennial plants are the main pollen and nectar sources for bees in the tropical areas where most of the annual flora are burned in dry seasons. Therefore perennial plants constitute the most reliable bio materials for determining and evaluating the beekeeping regions of the Republic of Benin. A silvo-melliferous region (S-MR) is a geographical area characterised by a particular set of homogenous melliferous plants that can produce timber. Using both the prevailing climatic and the agro-ecological conditions six S-MRs ...

How do consumers perceive organic food from different geographic origins? Evidence from Hong Kong and Shanghai
(Kassel University Press, 2015-05-21)
The objective of this paper is to understand how Chinese consumers perceive certified organic food, especially the differences between locally and nationally produced organic food compared to food produced overseas. In 2012, a consumer survey was conducted at supermarkets in Hong Kong and Shanghai (N=245). Participants were asked for their perception on four different food origins: locally produced organic food, organic food from China, imported organic food, and locally produced conventional food. Consumers in Hong ...

The Koundoum sheep breed in Niger: morpho-biometric study and description of the production system
(Kassel University Press, 2015-05-21)
The diffusion of highly productive breeds across developing countries goes along with a neglect of indigenous breeds, which are well suited to their environment but often show low yields. Thus, in Niger, the flock of Koundoum sheep are rapidly decreasing. The Koundoum is one of the few wool sheep breeds of Africa and shows important adaptive feature to its native environment, i.e. the humid pastures on the banks of the Niger River. To characterise the breed and to understand its production context, a survey has been ...

The prediction of seasonal and inter-annual climate variations and their impacts on the water resources in the eastern seaboard of Thailand
(2015-04-27)
The research of this thesis dissertation covers developments and applications of short-and long-term climate predictions. The short-term prediction emphasizes monthly and seasonal climate, i.e. forecasting from up to the next month over a season to up to a year or so. The long-term predictions pertain to the analysis of inter-annual- and decadal climate variations over the whole 21st century. These two climate prediction methods are validated and applied in the study area, namely, Khlong Yai (KY) water basin located ...

Zum Querkrafttragverhalten von UHPC-Balken mit kombinierter Bewehrung aus Stahlfasern und Stabstahl
(Kassel Univ. Press, 2015)
Ultrahochfester Beton besitzt aufgrund seiner Zusammensetzung eine sehr hohe Druckfestigkeit von 150 bis über 200 N/mm² und eine außergewöhnlich hohe Dichtigkeit. Damit werden Anwendungen in stark belasteten Bereichen und mit hohen Anforderungen an die Dauerhaftigkeit des Materials ermöglicht. Gleichzeitig zeigt ultrahochfester Beton bei Erreichen seiner Festigkeit ein sehr sprödes Verhalten. Zur Verhinderung eines explosionsartigen Versagens werden einer UHPC-Mischung Fasern zugegeben oder wird eine Umschnürung mit ...

Versuche zum Biegetragverhalten von UHPC mit kombinierter Bewehrung
(2011-12-16)
Das Biegetragverhalten von ultrahochfestem Beton (UHPC) mit einer kombinierten Bewehrung aus Stabstahl und Stahlfasern wurde im Rahmen des DFG-Schwerpunktprogramms 1182 untersucht. Dieser Forschungsbericht stellt die durchgeführten experimentellen Untersuchungen dar. Das Versuchsprogramm umfasste Referenzversuche zur Ermittlung der Materialparameter, Verbundversuche an Stabstahl und Stahlfasern, zentrische Zugversuche des faserbewehrten UHPC sowie Vier-Punkt-Biegeversuche an kombiniert bewehrten UHPC-Balken. ...
