The goal of this article is to give a Lefschetz type decomposition for the cd-index of a complete fan. To a complete simplicial fan one can associate a toric variety X, the even Betti numbers hi of X and the numbers gi = hi − hi−1. If the fan is projective, then non-negativity of gi follows from the Lefschetz decomposition of the cohomology. In the case of a nonsimplicial complete fan, one can ...

The sensitivity of MXT mouse mammary tumors to ovarian hormones was assessed by the following parameters: growth in vivo; presence or absence of estrogen receptors and progesterone receptors; and histological differentiation. A spontaneous evolution from hormone sensitivity (HS) to hormone independence (HI) was observed when the tumors underwent monthly transplantation onto intact recipient mic...

This experiment was conducted at Debre Zeit and Akaki during 2004-2005 cropping season on F2-derived F4 bulk families of three crosses, viz, DZ-01-974 x DZ-01-2786, DZ-01-974 x DZ-Cr-37 and Alba x Kaye Murri. To estimate the correlations and path coefficients between yield and yield components, 63 F4 families were taken randomly from each of the three crosses. The 189 F4 families, five parents ...

yield, harvest index and morphological characters of 13 spring cultivars of rapeseed were evaluated in 2007 growing season at agriculture and natural resources research station of torogh, mashhad. these cultivars were from three rapeseed species belonged to brassica napus, brassica rapa and brassica juncea. experimental design was randomized compelet block with four replication. result showed t...

OBJECTIVES The evaluation of hypoxia index (HI) in the prediction of abnormal fetal heart rate at delivery in uncomplicated pregnancies. MATERIAL AND METHODS The study group included 148 pregnant patients at term (69 patients with and 79 without brain sparing effect). The value of C/U ratio and HI was determined. Next, its value in predicting abnormal fetal heart rate during labor was evaluat...

introduction grain legumes are considered as the second source of human nutrition after cereals and play an important role in community food supply, sustainable agriculture and economic profitability. among grain legumes, common bean has the most consumption in the world compared with others. however there are always some constraints in common bean production and drought is most important facto...

the present study aimed at investigating the effect of different levels of nitrogen on yield and yield components of bread and durum wheat. to this end the experiment was conducted in 2010-2011 in south west of iran as split plots based on randomized complete block design with three replications. main plot included four levels of nitrogen 60, 120, 180, 240 kg.ha-1 and the sub plot included four...
