Newly hatched chicks will spontaneously peck at conspicuous objects in their field of view, and soon learn to distinguish between edible food particles and unpleasant tasting objects. To examine whether the selective pecking is based on the ability to memorize shapes, we analyzed pecking behavior of 1- to 2-days-old quail chicks (Coturnix japonica) by using ball- and triangle-shaped beads both ...

The development of sensor pins which can be easily integrated into ball screw drives for preload measurement is described in this paper. The sensor’s base body consists out of a steel pin with a special shaped load region. This complex surface is coated and structured with a sensory thin film system based on a hydrogenated carbon layer. The layer shows an excellent tribological stability combin...

Japanese pine sawyer beetle (Monochamus alternatus) is an economically important pest in coniferous trees. Ophiostoma ips was isolated from the beetle and identified based on analysis of morphological properties and the β-tubulin gene sequence. The fungus easily produced perithecia with a long neck on malt extract agar and its ascospores were rectangular shaped. This is first report of Ophiosto...

effect of fire on phyto-sociology of understorey vegetation in chir pine forests of three different silvological characteristics was compared with pure grassland. 15 grasses, 1 sedge, 5 legumes and 21 non-legumes were recorded in the four study sites. floristic composition gradually increased from june to august and then declined slowly by october in all the plots. maximum number of species was...

afghan pine one of the native tree species in eldar region of azerbaijan republic. fast growing, suited for dry climate condition, increasing wood in unit volume, reason of using eldar pine in reforestation and plantations. at this case study of absheron peninsular of baku, azerbaijan, were taken 14 trees samples of two sites. bbg, baku botanical garden and bmd, baku merdakandendrary, are two c...

In this paper, we introduce a wireless musical interface driven by grasping forces and human motion. The sounds generated by the traditional digital musical instruments are dependent on the physical shape of the musical instruments. The freedom of the musical performance is restricted by its structure. Therefore, the sounds cannot be generated with the body expression like the dance. We develop...

Stable rotor levitation is a challenge for rotational gyroscopes (magnetically suspended gyroscopes (MSG) and electrostatically suspended gyroscopes (ESG)) with a ring- or disk-shaped rotor, which restricts further improvement of gyroscope performance. In addition, complicated pick-up circuits and feedback control electronics propose high requirement on fabrication technology. In the proposed g...

INTRODUCTION 1,ongleaf pine (Pinuspalustris) once dominated the overstory of a wide range of southern plant communities including wet flatwoods and savannas of the Atlantic and Gulf coastal plains to higher, droughty sand deposits such as the fall line sandhills and the central ridge of Florida. It was also the dominant overstory tree on the lower rolling sandhills of lower Mississippi, central...

The Melbourne/Cochlear multiple-electrode extracochlear implant is designed for deaf patients who are unsuited to multiple-electrode intracochlear implantation. The implant consists of a receiver-stimulator package connected via a lead wire assembly to six individual stimulating electrodes. There is a choice of two alternative surgical procedures, both of which are via a combined middle ear app...

We consider the model of Deijfen et al. for the competing growth of two infection types in Rd, based on the Richardson model on Zd. Stochastic ball-shaped infection outbursts transmit the infection type of the center of the ball to all points of the ball that are not yet infected. Relevant parameters of the model are the initial infection configuration, the (typedependent) growth rates and the ...
