The experiment was conducted to determine optimum plant spacing and suitable variety as well identify the interaction effect of varieties Intra-row on yield sorghum. having a factorial arrangement three (Geremew, Lalo farmer’s local variety) intra-row levels (10 cm, 15 cm 20 cm) laid out in randomized complete block design (RCBD) with replications. According current results, were significantly ...

Typically, low-pressure sprayers are used to uniformly apply pre- and post-emergent herbicides to control weeds in crop rows. An innovative machine for weed control in inter-row and intra-row areas, with a unique combination of inter-row cultivation tooling and intra-row band spraying for six rows and an electro-hydraulic side-shift frame controlled by a GPS system, was developed and evaluated....

BACKGROUND AND PURPOSE For the localization of spinal dural arteriovenous fistulas, it is not determined whether dynamic contrast-enhanced MRA is more reliable than multidetector CTA. The aim of this study was to compare the agreement between intra-arterial DSA, dynamic contrast-enhanced MRA at 3T, and 64-row multidetector CTA for the localization of spinal dural arteriovenous fistulas. MATER...

This study attempts to optimize the arc-shaped coned disk affecting uniformity of earlier designed fertilizer apparatus (FA), in particular, for application rice–oil rotation region middle and lower reaches Yangtze River, China. Based on theoretical analysis, a circular with curvature gradual decline (GD) from top bottom was designed, equation cone determined. The EDEM discrete element software...

High performance storage layer is vital for allowing interactive ad hoc SQL analytics (OLAP style) over Big Data. The paper makes a case for leveraging flash in the Big Data stack to speed up queries. State-ofthe-art Big Data layouts and algorithms are optimized for hard disks (i.e., sequential access is emphasized over random access) and result in suboptimal performance on flash given its dras...

The objective of this research is the replacement of hand weeding in organic farming by a device working autonomously at field level. The autonomous weeding robot was designed using a structured design approach, giving a good overview of the total design. A vehicle was developed with a diesel engine, hydraulic transmission, four-wheel drive and four-wheel steering. The available power and the s...
