BACKGROUND The Lewis (LEW) and Fischer (F344) rat strains appear differentially sensitive to the aversive effects of several used and abused drugs. Naloxone, a mu opioid receptor antagonist that induces aversions in outbred rats but has no abuse potential, was assessed to determine the characteristics of compounds for which the strains differ. METHODS Opioid-naïve male LEW and F344 rats were ...

Component testing indicates that overheating in tropical buildings could be reduced using walls built from upcycled sand-filled plastic bottles, which also reduces building costs and prevents waste polluting the environment. It is not yet known, however, how these bottle-composite influence thermal comfort dwellings in-situ. This study presents world's first in-situ measurement of indoor temper...

The behaviour of bottle cells in normal and microsurgically altered gastrulae and in cultured explants of Xenopus laevis was analysed, using time-lapse micrography, scanning electron microscopy (SEM) and cell tracing with fluorescein dextran amine (FDA). The results shed new light on the function of bottle cells. Bottle cells forming in vivo show a predominantly animal-vegetal apical contractio...

We present a method to utilize the Shadow Volume Algorithm by Crow and Williams without using a stencil buffer. We show that the shadow mask can be generated in the alpha channel or even in the screen buffer, if a hardware-accelerated stencil buffer is not available. In comparison to the original stencil buffer method, a small speed up can be achieved, if the shadow mask is computed in the alph...

Intelligent empty bottle inspection system is an important inspection equipment of empty bottle before filling beer, and it is a blend of machine vision, precision machine and real-time control. They need to cooperate perfectly to achieve the desired effect. In the design of the empty bottle inspection system, one of the key technologies is the bottle bottom detection which affects the speed an...

Problem: The demand of beverages in PET bottles is constantly increasing. In this context, environmental, technological and regulatory aspects set a stronger focus on recycling. Generally, the reuse of recycled material from post-consumer PET bottles in bottle-to-bottle applications is seen as least environmentally harmful. However, closedloop systems are not widely implemented in Europe. Previ...
