A Heat Transfer Model to Predict Temperature Distribution in Stored Wheat

open access: yesJournal of Agricultural and Marine Sciences, 2000
The combined convective and conductive heat transfer model which previously developed by Abbouda er al. (1992) was applied in this study to simulate the temperatures of wheat grain during storage process using input data of initial grain temperatures ...

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

open access: yesAdvanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Neues Regressionsmodell mit einer Dummy-Variablen und geometrischen Zinkenparametern zur Vorhersage der horizontalen Kräfte einzelner Zinken

open access: yesLandtechnik, 2016
This paper discusses three different equations of a regression model to predict the horizontal force for single tines. Four standard single chisel plow tines were used (heavy duty, double heart, double heart with wings and duck-foot).

Mapping adaptation of barley to droughted environments [PDF]

open access: yes, 2008
Identifying barley genomic regions influencing the response of yield and its components to water deficits will aid in our understanding of the genetics of drought tolerance and the development of more drought tolerant cultivars. We assembled a population
