A Monte Carlo procedure is used to demonstrate the dangers of basing (farm) risk programming on only a few states of nature and to study the impact of applying alternative risk programming methods. Two risk programming formulations are considered, namely mean-variance (E,V) programming and utility efficient (UE) programming. For the particular example of a Norwegian mixed livestock and crop far...

BACKGROUND A knowledge based planning tool has been developed and implemented for prostate VMAT radiotherapy plans providing a target average rectum dose value based on previously achievable values for similar rectum/PTV overlap. The purpose of this planning tool is to highlight sub-optimal clinical plans and to improve plan quality and consistency. METHODS A historical cohort of 97 VMAT pros...

This paper proposes a model for strategic maintenance scheduling of offshore wind farms (SMSOWF) in a deregulated power system. The objective of the model is to plan the maintenance schedules in a way to maximize the profit of the offshore wind farm. In addition, some network constraints, such as transmission lines capacity, and wind farm constraints, such as labor working shift, wave height li...

In this article an on-farm monitoring approach on udder health is presented. Monitoring of udder health consists of regular collection and analysis of data and of the regular evaluation of management practices. The ultimate goal is to manage critical control points in udder health management, such as hygiene, body condition, teat ends and treatments, in such a way that results (udder health par...

This paper considers farmers willingness to pay (WTP) to conserve an endangered Irish farmland bird, the Corncrake (Crex crex). An Irish National Farm Survey (NFS) is used to produce individual farm-level WTP estimates for the year 2006. These figures are then aggregated to obtain a total value figure for the farming community of Corncrake conservation in Ireland. We focus on the willingness to...

The ultimate goal for using any recordkeeping system is to help make better management decisions. In particular, farm records should allow the owners to compare their operation to others or itself historically. Secondly, farm records should allow the owners to plan and evaluate proposed projects. For example, if a variety of projects are proposed, each project should be evaluated on how it woul...

In recent, Korea hog farm industry is facing FTA and stock farms are experiencing difficulties through increase in production cost such as raw & subsidiary material cost and energy cost. Although there are many elements that influence the productivity of hog farm, plan and execution of sow culling is very important. In majority of farms, there are many cases of not considering importantly of th...

Geochemical equilibrium speciation modeling was used to determine optimum conditions for precipitation of magnesium ammonium phosphate, or struvite, for the recovery of nutrients from anaerobically digested wastes. Despite a wide range of pH values with the potential to precipitate struvite, the optimum pH was determined to be 9.0. Bench experiments conducted on effluent from an anaerobic seque...

As part of its food security policy, South Korea has been pursuing food selfsufficiency using high tariffs and high administrative prices in key agricultural and food markets. Using a dual approach to trade and trade restrictiveness indices, we analyze the impact of these market distortions on welfare and trade volume. Then, we compute optimum distortions, which minimize the welfare costs of ob...
