Information on the effect of long-term management on soil nutrients and chemical properties is scanty. We examined the 30-year effect of tillage frequency and cropping sequence combination on dryland soil Olsen-P, K, Ca, Mg, Na, SO4-S, and Zn concentrations, pH, electrical conductivity (EC), and cation exchange capacity (CEC) at the 0-120 cm depth and annualized crop yield in the northern Great...

We describe the locomotion dynamics of a biomimetic robot and compare them with those of its exemplar: the cockroach. The robot is a small (0.275kg) hexapod created using a layered manufacturing technique that allows us to tailor the compliance and damping of the limbs to achieve passive stabilization similar to that observed in insects. The robot runs at over 3 body-lengths per second (55 cm/s...

The paper tests for the backward linkage hypothesis of multinational firms in developing host economies. The empirical case is the Polish food industry expected to be a highly relevant European case as the largest magnet of ‘developing-oriented’ FDI over the last decade. Combining the case study, descriptive and econometric evidence suggests that backward linkage creation has failed in terms of...

White matter hyperintensities (WMH) are commonly observed in elderly people and may have the most profound effect on executive functions, including working memory. Surprisingly, the Digit Span backward, a frequently employed working memory task, reveals no association with WMH. In the present study, it was investigated whether more detailed analyses of WMH variables and study sample selection a...

In this study, we have designed and implemented a system that supports learners to use backward chaining to solve proof problems about the congruence of two triangles. In addition, we have carried out an evaluation experiment in a public junior high school to measure the learning effect of the system. As a result of hypothesis tests, for students with good pretest scores, the effect of the syst...

this study was undertaken to investigate the effect of long-term reduced tillage on grain yield, grain quality, and weed infestation of spring wheat. the experimental variables were three tillage systems: (a) conventional tillage (ct): shallow ploughing (10-12 cm) and harrowing after harvest of the previous crop, ploughing (25-30 cm) in the autumn; (b) reduced tillage (rt): only a cultivator (1...

This paper addresses a previous claim (Brysbaert & Praet, 1992) that the use of prelexical phonology in visual word recognition is optional in the Dutch language. One backward masking experiment and two masked priming experiments are reported. The experimental task was perceptual identification. Pseudohomophones, graphemic controls, and unrelated controls of the target words were used as masks ...

In this study, it is theorized that party websites play a distinctive role in two regards: (i) they function as a pluralistic civic forum by facilitating the voice of oppositional challengers and increasing the visibility of minor and fringe parties, so that attentive citizens can learn more about the range of electoral choices; (ii) in addition, party websites function as a channel for politic...
