This paper describes the development of a 3D model of the non-domestic building stock of England and Wales. The model’s purpose is to assess energy use in the stock, and study conservation options. Previous stock models have used data on floor area by activities, and have not represented building geometry. The present model by contrast combines digital maps and property taxation data to build a...

In the early 1980s, nitrogen (N) deposition was first postulated as a cause of N saturation and spruce mortality across the northeastern US. In 1988, a series of high elevation spruce-fir forest N addition plots were established on Mt. Ascutney (southeastern) Vermont to test this hypothesis. The paired plots each received, in addition to ambient N deposition, 15.7 kg N ha-' (low N addition), 31...

We sought to quantitate infarct size using radioactive imaging techniques. Infarcts were created in closed chest dogs. Using a scintillation camera interfaced to a computer, infarct images were made in the anterior, left lateral, LAO, and RAO projections, 48 hours after infarction and 75 to 90 min following the intravenous injection of 15 mCi of Technetium 99m pyrophosphate (Tc-PYP). Images wer...

This paper develops hedging strategies for an electricity distributor in the Nordic electricity market who manages price and volume risk from fixed price agreements on stochastic electricity load. Whereas the distributor trades in the spot market at area prices, the financial contracts used for hedging are settled against the system price. Both the area price and the system price are correlated...

greenhouse structure has an important role in success of greenhouse production. this research was conducted to study problems related to vegetable greenhouse structure in khuzestan province for on year(2011-2012). for this purpose, 21 greenhouses were selected by simple randomized samplang and questionnaires were completed. the results revealed that the major problems in greenhouses vegetable p...

sugar beet is one of the major products in qazvin plain that allocated most of planting areas to itself after wheat, barley and corn. in recent years, restriction on water resources decreased sugar beet planting area in this plain. therefore, in this study, the effects of increase in sugar beet planting area on planting pattern, grower's gross profit, and inputs utilization under water sho...

the study assessed economic of maize production in ogori/magongo local government area of kogi state. to this end, effort was made to examine the socio economic characteristics of the maize farmers, determine the resource use efficiency, problems as well as profitability of maize production in the area. to achieve the objectives of this study 48 maize farmers where randomly selected from 5 ward...

This study assessed the efficacy, safety, and technical feasibility of inducing bone formation in an animal model of maxillary sinus floor augmentation using recombinant human bone morphogenetic protein-2 (rhBMP-2) impregnated on an absorbable collagen sponge (ACS). Bilateral antral maxillary sinus floor elevation procedures were surgically performed in six adult female Alpine-Saanen goats. Bon...

BACKGROUND The quality of the floor is essential to the welfare of piglets as abrasions often are recorded in newborn piglets, and such lesions may lead to lameness. Apart from animal suffering, lameness contributes to losses in form of dead piglets, decreased growth, and increased use of antibiotics and manual labour. METHODS In a herd with three different farrowing systems, 37 litters (390 ...
