in order to investigation of sowing date effect on yield of millet species and its impressible from duration of phonological periods and development rate, an experiment was conducted based on complete randomized block design as combine analysis in four replications at eight sowing dates (30 april, 1 jun, 31 may, 4 july, 5 august, 1 september, 2 october and 3 november) and three millet species (...

The early evolution of living birds has been sharply debated, with two disparate interpretations. Molecularclock studies consistently date the emergence of modern bird orders at ,100 million years ago or older, coincidental with major continental breakup. This is supported by some biogeographers who use phylogenetics, accept an ancient evolutionary origin and use historical geology to guide the...

This paper describes the development of a v ision-based finger track ing system for media art; the system utilizes an infrared camera and a Kalman filter to accomplish this finger recognition image processing technology . The system is stable and fast, and is able to recognize not only gestures but also the speeds of gestures. Our work , called the "Narrative Hand", switches movies to show the ...

Environmentally cued plasticity in hatching timing is widespread in animals. As with later life-history switch points, plasticity in hatching timing may have carryover effects that affect subsequent interactions with predators and competitors. Moreover, the strength of such effects of hatching plasticity may be context dependent. We used red-eyed treefrogs, Agalychnis callidryas, to test for la...

introduction lentil (lens culinaris medik.) is an important legume in the mediterranean area. high protein content in lentil seed (about 22-28%) makes it as a good food source for developing countries and low-income people. in the west of iran such as kermanhah province, it is the most important pulse in rainfed systems cultivated traditionally in rotation with wheat and barley. lentil is grown...

to assess required growing degree days (gdd) for phenological stages of four clover species in different planting dates a field experiment was conducted in 2010-11 and 2011-12 cropping seasons in seed and plant improvement institute in karaj, iran. three planting dates (14 september, 28 september and 13 october) and six clover varieties were assigned to main plots and sub-plots, respectively, a...
