water deficit is one of the most common constraints to crop productivity in the world and iran. in order to study effect of drought stress on morphologic traits, yield and yield components of 34 hybrids of corn, an experiment was carried out based of complete randomized block design with three replication under f.c. irrigation and drought stress in khorasan razavi agricultural research and natu...

Using the StarTrack binary population synthesis code we investigate the properties of population of compact object binaries. Taking into account the selection effects we calculate the expected properties of the observed binaries.We analyze possible constraints on the stellar evolution models and find that an observed sample of about one hundred mergers will yield strong constraints on the binar...

almost half of agricultural lands in iran are saline and it is one of the most important constraints in cultivated lands. wheat is the most important crop in saline lands in rotation of golestan province. since saline soils amelioration is so expensive, achievement of genotypes with tolerant and high yield potential is essential. 22 genotypes of selective wheat of recent experiments with three ...

Mulberry (Morus spp.) is a perennial tree cultivated for its foliage to rear the domesticated silkworm, Bombyx mori L. Mulberry has improved through conventional breeding in general aims to improve the quantity and quality of leaf yield, which have direct bearing on silk productivity. Leaf senescence is one of the major constraints, which restricts the quantity of quality leaf availability for ...

The Sikkim Mandarin (Citrus reticulata) is one of the most important fruit crops for ages. valleys Tista and Rangeet rivers their tributaries adjoining Darjeeling district West Bengal offer an ideal Himalayan climate cultivation Mandarin. Analysis shows that during 2020-21 produced 26.65 MT mandarin from 13.26 thousand hectares land with a productivity 2.01MT /ha. It was seen there had been inc...

The problem of finding a next best viewpoint for 3D modeling or scene mapping has been explored in computer vision over the last decade. This paper tackles a similar problem, but with different characteristics, and proposes a method for dynamic best viewpoint recovery of a target point while avoiding possible occlusions. Since the environment can change, the method has to iteratively find the n...
