Planning of modifications of existing wind farms by adding or replacing turbines makes new demands on wind farm modelling. Emphasis shifts from the calculation of the mean efficiency of the farm to that of individual turbines. Additionally, modelling has to deal with different turbine types and hub heights combined in one farm. Full scale measurements at two wind farms in Northern Germany provi...

We explored observed risk factors and drivers of infection possibly associated with African swine fever (ASF) epidemiology in Uganda. Representative sub-populations of pig farms and statistics were used in a case-control model. Indiscriminate disposal of pig viscera and waste materials after slaughter, including on open refuse dumps, farm-gate buyers collecting pigs and pig products from within...

Increasing population growth and decreasing land ratio made it difficult for rural people of Bangladesh to maintain their livelihood. Especially the small-scale farmers find it trickier using their scarce resources. One House One Farm approach(OHOF) is designed to utilize the house and farm resources of the small- scale farmers to improve their livelihood. The focus of the study was to determin...

The technique of the processor farm has become very widely used for paral-lelising applications, often being mentioned without reference to any source. The goal of this work has been to put together a complete and rigorous understanding of what the technique can be used for and what is needed in order to arrive at an eeciently farmed application. This paper consists of these two parts. We have ...

This contribution is based on the personal experiences of the author as a typical crop farmer in Holland in 1925-1991, as a researcher at the Dutch Institute of Agricultural Engineering (19541964), and as the Director of that Institute in the period 1964-1983. In essence, the 20th century developments in mechanized agriculture are considered from a historical perspective. The future of farm mec...

In order to assess the extent of genotype by environment interactions (G×E) and environmental sensitivity in sheep farm systems, environmental factors must be identified and quantified, after which the relationship with the traits(s) of interest can be investigated. The objectives of this study were to develop a farm environment (FE) scale, using a canonical correlation analysis, which could th...

The New Generation Cooperatives: Case Studies are made possible with support from the Illi-nois Council on Food and Agricultural Research (C-FAR) and the Illinois Institute for Rural Affairs (IIRA). A collection of ten case studies with an introduction is available from IIRA in print and on the IIRA web page. Quoting from these materials for noncommercial purposes is permitted provided proper c...

As modern society grows more reliant on wind energy, wind farm deployments will become increasingly attractive targets for malicious entities. The geographic scale of wind farms, remoteness of assets, flat logical control networks and insecure control protocols expose wind farms to myriad threats. This paper attempts to clarify the gaps in the understanding of wind farm threats and their implic...

Decreasing enteric methane (CH4) emissions from ruminants without altering animal production is desirable both as a strategy to reduce global greenhouse gas (GHG) emissions and as a means of improving feed conversion efficiency. The aim of this paper is to provide an update on a selection of proved and potential strategies to mitigate enteric CH4 production by ruminants. Various biotechnologies...

The increasing popularity of urban agriculture as a method of localizing food systems has created a mounting need to address soil pollution in urban farms. Lead is an especially pervasive pollutant in urban soils with a number of detrimental health effects. Phytoremediation, the use of plants to extract or degrade pollutants, has shown promise for cleaning up leadcontaminated soils, yet its pot...
