Desde hace muchos años, los jardineros han usado
el compost para mejorar la tierra. Hoy en día también
es una manera importante de reducir la cantidad de
basura que se quema o se añade a los vertederos
públicos. Los desperdicios de jardín y cocina
constituyen hasta el 20 por ciento...
Pacific Northwest vegetable and fruit growers always have faced changing markets. To many growers, these changes have seemed faster than usual in recent years, fueled by shifting consumer preferences, increasing production costs, and new market logistics. The number of processing plants in the region continues to decline. Typically, plant closures...
The spreadsheet has become a common technology tool and is now a predominant form of end-user programming. Some of the same features that make spreadsheets excellent tools for ad-hoc development can introduce errors into the final product. Although a variety of research has been performed investigating methods to detect errors...
In developed country markets, the consideration of consumer wants has not been prominent hitherto in aquaculture production decisions. Like capture fisheries aquaculture has been product driven. This supply-side focus reflects an emphasis upon technical solutions to the production and capacity problems of high unit value (HUV) species culture. Whilst this...
As the various mechanisms of fisheries resources management have matured, fishermen increasingly have responded by devising and developing different forms of collective representation. Within the European Union (EU), Producer's organisation (POs) provide a voluntary organisational structure which has evolved since its inception in the 1970s. During the intervening period, POs...
With heightened media attention on the poor state of world fish stocks and the environmental impacts of aquaculture production methods, both governments and seafood industries are keen to demonstrate support for improved management measures. This paper includes results from a DFID funded project concerned with seafood certification, ecolabelling and developing...
Hydrogen sulfide and related sulfur compounds produced internally by yeast during fermentation are considered highly undesirable if they are excreted and exceed threshold concentrations in the finished wine, as they cause an unpleasant "reduced character". The threshold for hydrogen sulfide is on the order of parts per billion and that...
The objectives of this research project are to understand tannin and anthocyanin changes during berry development in Pinot noir fruit and wines. Specifically, the objectives of this research project are:
· Determine the effect of berry development on the composition of tannins in cv. Pinot noir berries
· Determine the...
Because of wild salmon's importance as a commercial fishery in North America, many questions and concerns have been raised around the issue of farmed versus wild salmon in recent years. Concerns have been related to the impact of the tremendous growth in farmed salmon production on the markets for wild...
A time history of the calibration coefficients for channels 1 and 2 of the Advanced Very High Resolution Radiometer (AVHRR) on the NOAA-12 and NOAA-15 spacecraft is presented. The history is based on reflectances observed for the interior zones of the Antarctic and Greenland ice sheets previously obtained with the...
