| Ziel dieses Projektes war es, eine Charakterisierung des seuchenhygienischen Zustandes von flüssigem Gärgut aus Schweizer Vergärungsanlagen in Relation zu den Ausgangsmaterialien und zu den angewandten Techniken der Vorbehandlung, der anaeroben Vergärung und der Nachbehandlung durchzuführen. Drei Probenahmekampagnen wurden durchgeführt: im Winter 2012-2013, im Frühling 2013 und im Sommer 2013. Dabei wurden repräsentative thermophile und mesophile Vergärungsanlagen detailliert untersucht. Die verschiedenen Ausgangsmaterialien sowie Gärgut in verschiedenen Prozessstufen wurden auf die Leitkeime Salmonellen, Coliforme, E. coli, Enterokokken und teilweise Campylobacter untersucht. Die Inputmaterialien mit dem grössten Erregerbesatz sind Grüngut und... |

| Glutathione peroxidases are selenium-dependent, antioxidant enzymes that catalyse the removal of hydroperoxides using the tripeptide glutathione as reducing substrate. The presence and importance of glutathione peroxidase for the oxidative stability of bovine milk is unclear. We failed to detect any specific activity in bovine milk using careful and comprehensive assay conditions. The apparent activity in milk that has been ascribed previously to glutathione peroxidase was shown to be independent of added hydroperoxide, completely inhibited by >6 mM EDTA, and could not be immunoprecipitated with a specific antiserum against the extracellular form of glutathione peroxidase. These results are incompatible with activity of glutathione peroxidase in bovine... |

| Key Policy Message: - Despite having relatively low population densities, inadequate access to land is one of the major causes of rural poverty in Zambia. - The apparent paradox of inadequate access to land for many rural households in a country of low population density is partially reconciled when taking into account that economically viable arable land requires at least some degree of access to basic services, water, road infrastructure, and markets. The basic public investments to make settlement economically viable have yet been made in many areas of Zambia. - Depending of future land allocation policy, access to good quality land with a market potential may become increasingly beyond the reach of many small-scale farm households, making it more... |

| By heating up carbohydrate-rich food, like cereals and potatoes, Acrylamide (AA), a probably carcinogen food ingredient, will be created due to a reaction of free Asparagine (Asn) and reducing sugar within the Maillard-Reaction. Up to now two opportunities to decrease AA are discussed. Firstly by changing technological food processing steps e.g. receipt modifications and secondly by plant production e.g. finding species and cultivars low in the content of precursors of AA. For cereals, free Asn is the limiting factor for formation of AA. By investigations of conventionally produced wheat-, spelt- and rye samples differences were found in the amount of Asn both in species and cultivars. It was assumed that these differences could also be found in... |

| The aim of this study was to describe actions in family care and use of medicinal plants by women farmers in the south of Rio Grande do Sul, RS, Brazil. This is a qualitative study with a group of 15 women farmers from District of Rincão da Cruz, Pelotas, RS. Data were collected in 2011 and 2012. Participant observations, focus groups, and individual interviews were performed, resulting in two thematic cores. The theoretical reference for this study was based on publications by Geertz and Leininger. Content analysis of discourses was developed in three stages: pre-analysis, analysis, and interpretation of results. These women were shown to have knowledge on medicinal plants and the most prevalent diseases in the region. This knowledge is used in the... |

| Several types of studies can be used to elucidate various aspects of the effect of food on human health. The main categories are: • Epidemiological (observational) studies with humans. These can be prospective, where the diet is recorded and health indicators are moni-tored after the first recording, or retrospective, where people who have a disease are identified and it is then investigated if their diet has been different from those who did not get the same disease. • Intervention studies with animals or humans, where the outcome is differences in indicators of health between groups eating different controlled diets. • In vitro studies, where specific aspects of the mechanisms of the effects of food or food com-ponents are studied in cell cultures,... |

| This paper examines how the fertilizer sector in general, and farmers’ demand for fertilizer in particular, has evolved since the introduction of fertilizer sector reforms in Ethiopia. There is much debate in the agricultural development literature about whether fertilizer use in Africa is constrained primarily by poor input distribution systems, by farmers’ lack of knowledge concerning the benefits and correct use of fertilizer, or by lack of effective demand because the product is simply not profitable enough. This paper looks at each of these issues in an effort to understand the relative importance of the different constraints and how well current policies are addressing the problems. It attempts to identify additional policy measures needed to... |
