The efficiency of different types of traps for catching of the Caspian Sea crayfish, Astacus leptodactylus eichwaldi, was investigated from Mar. 2002 to Feb. 2003. Totally 56 traps of four most commonly used types, "Rectangular trap", "Round trap", "Opera house trap" in two colors of "black" and "blue", and "Fathoms plus" only in black...

Tracking objects that are hidden and then moved is a crucial ability related to object permanence, which develops across several stages in early childhood. In spatial rotation tasks, children observe a target object that is hidden in one of two or more containers before the containers are rotated around a fixed axis. Usually, 30-month-olds fail to find the hidden object after it was rotated by ...

background: toxic and hazardous heavy metals like arsenic, lead, mercury, zinc, chromium and iron are found in a variety of personal care products, e.g. lipstick, whitening toothpaste, eyeliner and nail color. the nails absorb the pigments of nail polishes and vaporized or soluble metals can easily pass it. the goal of this survey was to assess whether the different colors of nail polishes comp...

Recently, it has been demonstrated that people associate each of the basic tastes (e.g., sweet, sour, bitter, and salty) with specific colors (e.g., red, green, black, and white). In the present study, we investigated whether pairs of colors (both associated with a particular taste or taste word) would give rise to stronger associations relative to pairs of colors that were associated with diff...

--The possibility of growing sizeable shade trees (1%" and over in caliper) in containers is exciting to both arborists and nurserymen. Advantages include reduction in transplant shock, ease of retail storage, extension of the planting and shipping seasons, and less need for nursery space. However, problems include difficulty in overwintering in northern climates, root girdling, potbound trees,...

Deep planting is recommended in Nordic countries only for normal-sized container seedlings planted on mounds. Its effects smaller-sized are poorly understood. We studied the of depth early field performance small-sized silver birch (Betula pendula Roth) and Scots pine (Pinus sylvestris L.) seedlings. Silver (mean height 16 cm) were to depths 3, 6 8 cm spot mounds May 2016. 9 2, 5 inverted Septe...

On dermoscopy, the amount and location of melanin pigment can be assessed on the basis of its colors, ranging from black, brown to blue-gray. However, accurately recognizing a variety of melanin colors is sometimes difficult because the color of melanin pigment might change according to the character and intensity of lighting, and small melanin particles of different colors might be intermingle...

This paper introduces a new color model, RBW, which can be used as an intuitive user-interface for selecting colors in computer graphics systems. It is based on the red-green, blue-yellow, and white-black color axes. These axes are similar to the axes in opponent color theory, but their semantics are different: in the RBW model, the white-black axis mixes white or black into the color rather th...
