Farm tractor skidding is one of the common methods of timber extraction in Turkey. However, the absence of an optimal skidding plan covering the entire production area can result in time loss and negative environmental impacts. In this study, the timber extraction by farm tractors was analyzed, and a new skid trail pattern design was developed using Linear Programming (LP) and Geographical Info...

The northern Gulf of Aqaba is an oligotrophic water body hosting valuable coral reefs. In the Gulf, phytoplankton dynamics are driven by an annual cycle of stratification and mixing. Superimposed on that fairly regular pattern was the establishment of a shallow-water fish-farm initiative that increased gradually until its activity was terminated in June 2008. Nutrient, water temperature, irradi...

Events of the 1990s seem to have given the small farm a new lease on life. Organic agriculture offers a means of producing considerable profitability on very small areas even if many small farmers are of necessity only part-time farmers. Opportunities off the farm, however, have enabled owners of small parcels to farm them profitably, or at least sustainably. Urban agriculture is now a respecte...

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...

Quantifying the likely effects of offshore wind farms on wildlife is fundamental before permission for development can be granted by any Determining Authority. The effects on marine top predators from displacement from important habitat are key concerns during offshore wind farm construction and operation. In this respect, we present evidence for no significant displacement from a UK offshore w...

BACKGROUND Pre-weaning diarrhea in mink, also known as "sticky kits", is a syndrome and outbreaks occur every year on commercial mink farms in all mink producing countries. Morbidity and mortality can be considerable on a farm with huge economic consequences for the farmer as well as compromised welfare for the mink kits. Although efforts have been taken to identify etiologic agents involved in...

Brucellosis, a zoonotic disease particularly affecting goats, emerged in Thailand in 2003, resulting in both an occupational hazard for goat keepers and livestock officers, and production losses. Farm management practices have been identified as risk factors associated with Brucella sero-positivity in many studies. Our finding in this study should be considered in order to strengthen the system...
