Cover crops can improve soil health by maintaining organic carbon (SOC) and nitrogen (N) contents, yet their dynamics in relation to crop yield a semi-arid cropping system are poorly understood. The main objective of this study was evaluate the response diverse winter cover species mixture on SOC N fractions relationship with sorghum (Sorghum bicolor L. Moench) wheat (Triticum aestivum L.)–sorg...

In recent years, compatibilism has been the target of two powerful challenges. According to the consequence argument, if everything we do and think is a consequence of factors beyond our control (past events and the laws of nature), and the consequences of what is beyond our control are themselves beyond our control, then no one has control over what they do or think and no one is responsible f...

and more intelligent than women but, strangely, it is the fate of each man to become the willing slave of some woman, without knowing how this takes place. The book is full of generalizations, most of them inaccurate. Feminine and masculine roles are sharply divided. Long hair, colourful clothes, toilet aids, and artistic interests are presented as a denial of masculinity: the feminine mind is ...

A new computational framework for the simulation of turbulent flow through complex objects and along irregular boundaries is presented. This is motivated by the application of metal foams in compact heat-transfer devices, or as catalyst substrates in process-engineering. The flow-consequences of such complicated objects are incorporated by adding explicit multiscale forcing to the Navier–Stokes...

We study information aggregation with a biased election organizer who recruits voters at some cost. Voters are symmetric ex-ante and prefer policy a in state A and policy b in state B, but the organizer prefers policy a regardless of the state. Each recruited voter observes a private signal that is imperfectly informative about the unknown state, but does not learn the size of the electorate. I...

Direct seeded canola (Brassica napus L.) has become increasingly popular in China’s key canola-producing regions. The studies on the K response of direct-seeded performance are limited. This research aimed to investigate utilization efficiency and canopy radiation interception rate direct winter at various application rates. Two seasons field trials were done with five levels (0, 75, 150, 225...

ABSTRACT Eight different 3-year cropping systems, consisting of soybean-canola, soybean-barley, sweet corn-canola, sweet corn-soybean, green bean-sweet corn, canola-sweet corn, barley-clover, and continuous potato (non-rotation control) followed by potato as the third crop in all systems, were established in replicated field plots with two rotation entry points in Presque Isle, ME, in 1998. Cro...

This study identifies and analyzes factors influencing canola plantation development in Tabriz and Marand Counties. The Censored Model was used to analyze cross-sectional data collected from 372 farmers using a questionnaire. Due to the weakness of the Tobit Model in separating factors affecting the adoption decision of farmers and factors affecting the rate of adoption, the Heckman Model was e...
