The influence of the painting process on a biocompostable waste is studied. Disintegration degree (D %) of a 100% biocompostable plastic made from potato almidon is calculated for both painted and non -painted samples. Solid matrix is also characterized by means of a laboratory scaled composting process following UNE-EN norms [2, 3]. It can be concluded that painting has a negative influence on...

Biotin-binding proteins (BBPs), such as avidin and streptavidin, represent potent insect control compounds which could be delivered via transgenic plants. The effects of BBPs on some pasture pests were determined. Black field cricket nymphs (Teleogryllus commodus) had significantly reduced growth and survival when fed on lettuce leaves painted with purified avidin. Adult clover root weevils (Si...

The present experiment was designed to examine the roles of painted linear perspective cues, and the convexity bias that are known to influence human observers' perception of three-dimensional (3D) objects and scenes. Reverse-perspective stimuli were used to elicit a depth-inversion illusion, in which far points on the stimulus appear to be closer than near points and vice versa, with a 2 (Type...

In damselflies, sexual colour dimorphism is commonly explained as a consequence of selection on traits that increase male attractiveness to females. However, while many species in the damselfly family Coenagrionidae (Insecta: Odonata) are sexually dimorphic, the males do not engage in displays, and male competition for mates resembles a "scramble". An alternative explanation for the sexual diff...

Schizophrenia patients are less susceptible to depth inversion illusions (DIIs) in which concave faces appear as convex, but what stimulus attributes generate this effect and how does it vary with clinical state? To address these issues, we had 30 schizophrenia patients and 25 well-matched healthy controls make convexity judgments on physically concave faces and scenes. Patients were selectivel...

Large, bold marks are painted or incised on the handles or bases of thirty-seven pictorial vases. These same kinds of marks and same patterns of marking are found on non-pictorial Mycenaean pottery. In general, marks on Mycenaean pottery are rare and the circum­ stances of their use are not yet fully understood. It is clear that they are associated with Cyprus, and it is most likely that they a...
