Proso millet (Panicum miliaceum L.) is well-adapted for the Central Great Plains and could be planted in a winter wheat (Triticum aestivum L.)-millet-fallow rotation, resulting in two crops in 3 yr. To determine the most suitable tillage system for proso millet production within this rotation, seven tillage management systems were evaluated over a 6-yr period (1972-1977). The research was condu...

Reading Roma Correu is a surprise and gift, it allows us to resume the thread of an interrupted correspondence, reconciles instigates recover reinvent our role as actors on that great theater landscape. The vision four authors intertwines here, giving scene we have not been able tread. As generous letter, recomposes dialogue warmly inviting re-encounter with city, which fills void current abili...

This paper presents a method for animating and rendering an interactive natural scenery in real-time. It improves the prairie model of [11] by enabling the on-the-fly generation of blades of grass, at three different levels of detail, from user-specified density maps. A new animation function, the tread on grass, is defined to allow virtual objects or characters to crush the grass. The resultin...

Falls near the bottom of a flight of stairs have resulted from an illusion that the person was stepping off onto the bottom landing when the person was still two treads or more above the landing. The illusion is caused by poor lighting and design defects built into the stairway. The poor lighting may be attributed to a building code that allows inadequate lighting near the bottom of external st...

The paper introduces mathematical models of a skid steered mobile platform for robotics. The platform consists of a rectangular steel construction with four wheels. Two banks of two drive wheels on each side are linked to two DC electrical motors via chain on sprocket drive and gearing. The two drive assemblies for the left and right banks are identical but they operate independently to steer t...

The use of retention gifts in clinical trials has been controversial, with some ethicists maintaining that such gifts represent undue inducement to the trial participants. A study was conducted at TREAD Research, a site-managed organisation based at Tygerberg Hospital, in which 302 participants completed a questionnaire that focused on their opinion with regard to such gifts. The results sugges...

It has been observed that denoising of ECG is done in stationary condition i.e. when the patient under scanner is lying on bed or in rest condition. This is very common case and the noise added in this condition can be removed by many different methodologies like FFT, wavelet, ICA etc. However, when the ECG is monitored in dynamic condition e.g., on tread mill testing, the noise inserted due to...
