About 2/3 of the initial complement of transplants were lost between December 5 and January 5. Mortality during the next 20 days declined, as only about one third of the remaining plants disappeared. A short but violent squall on January 30 destroyed the last of the transplants. Tangling with and abrasion on various parts of the test farm structure were the sole causes of plant mortality.

The polyether antibiotics were first recognized as a separate class with the pubHcation of the structure of monensia ia 1967 (1). Several members of the group have siace found commercial appHcation as anticoccidials ia poultry farming and ia improvement of feed efficiency for mmiaants (see Feeds and FEED additives). 

The open-terrain factor should be used if the release occurs in flat terrain and few structures are nearby, for example, in an isolated tank farm consisting of one or two well-spaced tanks. Otherwise, the partial-confinement yield factor should be used to give reasonably conservative damage estimates. 

Complex structures such as tank farms, tank bottoms and marine installations have complicated attenuation patterns and it is not feasible to use complex equations to determine the effect. This must be determined by a current drain test or by practical experience. For pipelines the attenuation depends on the linear resistance of the pipe, coating resistance, and to some extent the resistivity of the soil. Connections to foreign structures and the method of termination of the line also affect the attenuation (see Section 10.1). 

Before mechanical refrigeration systems were introduced, people cooled their food with ice and snow, found or made on-site or gathered in the mountains. This practice survives today in the Taurus Mountains of Turkey. Ice was stored in icehouses usually partially buried in the ground and lined with straw or sawdust. Remains of these structures survive on many farms in Europe and North America. Ice has long been used for space comfort conditioning. In the early nineteenth century, ice was placed in air ducts to cool and dehumidify warm air blown by fans. 

The predictions for almost all communities in Canada include more violent winter storms, very high intensity rainfalls of short-duration, and extended heat waves with the accompanying increased risk of smog, wildfires, tree parasites, severe thunderstorms and tornadoes. Current structural design, farming,... 

Within plant production, in organic farming, there is space for reducing greenhouse gas emissions per the production unit and an increase in income, while maintaining the current input structure. 

Given the controversy and uncertainties regarding the relative quality and safety of organic foods, and the lack of structured textbooks describing the current state of the art with respect to quality and safety assurance in organic food and farming systems, the Handbook of organic food quality and safety aims to ... 

Predation (e.g. by foxes and birds of prey) may also be a serious cause of mortality in free-range husbandry. Foxes can be kept away with a solid fence, which can be supplemented by an electric fence. Birds of prey are not a big problem for poultry houses that are closed at night and free of holes. However, keeping birds of prey such as the hawks away is not easy, especially for farms surrounded by forest or in a landscape with a lot of trees. In such situations, low structures should be provided as hiding places for the hens.
