The relation of the yield stress of high-pressure anvils to the pressure attained at yielding and the ultimate attainable pressure

Journal of Applied Physics, 1979
Using a sensitive microprofilometer, the onset of yielding in the anvils of a supported opposed anvil device can readily be determined. If the pressure at which yielding occurs is measured, the yield stress of the anvil material can be obtained. This is illustrated for 3% cobalt cemented tungsten carbide. The reverse is also true and can be used as the

Rice yields in Nepal: Is the 4-tons per hectare yield goal attainable?

Journal of Asian Economics, 1993
Abstract In recent years, rice production in Nepal has not kept pace with the population growth. As a result, the government of Nepal has called for a rice yield goal of 4-tons per hectare. This is about double the current average yield for the country.

Attainment of the Theoretical Yield of Carbon from Biomass

Industrial & Engineering Chemistry Research, 2000
Previous work has shown that very high yields of charcoal are obtained when pyrolysis of the biomass feedstock is conducted at elevated pressure in a closed vessel, wherein the pyrolytic vapors are held captive and in contact with the solid products of pyrolysis.

Attainable yield and soil texture as drivers of maize response to nitrogen: A synthesis analysis for Argentina

Field Crops Research, 2021
Abstract The most widely used approach for prescribing fertilizer nitrogen (N) recommendations in maize (Zea Mays L.) in Argentina is based on the relationship between grain yield and the available N (kg N ha−1), calculated as the sum of pre-plant soil NO3--N at 0−60 cm depth (PPNT) plus fertilizer N (Nf).

Attainable CO2 Emission of Ware Potatoes Under High Yield Conditions in Southern Chile

American Journal of Potato Research, 2015
The objective of the analysis was to calculate the attainable CO2 emissions associated with the production of one ton of potatoes in a high yield environment in southern Chile. Two field experiments were performed. The first field experiment used an optimal sowing date while the second experiment used a late sowing date.

Bridging the attainable yield gaps of watermelon through nitrogen and phosphorus nutrients management in North-West Ethiopia

Journal of Plant Nutrition, 2021
Optimum fertilizer is essential for obtaining high yields of watermelon. This three location study was conducted to investigate the effect of nitrogen and phosphorus (NP) fertilizer on the growth a...

Attainable yield achieved for plastic film-mulched maize in response to nitrogen deficit

European Journal of Agronomy, 2014
a b s t r a c t Nitrogen (N) stress limits the yields of maize (Zea mays L.) that have been plastic film-mulched in northwest China. Using the tested Hybrid-Maize simulation model, which was combined with field experiments using four levels of N fertilisers (0, 100, 250 and 400 kg N ha −1 ), we aimed to understand the variability of the attainable ...

Using a simulation model to assess potential and attainable sugar cane yield in Mauritius

Field Crops Research, 2000
Abstract The Mauritian sugar cane ( Saccharum spp.) industry is characterised by high climatic variability both from year-to-year and across agro-climatic zones. There is a need to assess yield variation with a view to facilitate crop management as well as investment decision-making, such as irrigation schemes. The aim of this study is to assess the
