the role of endogenous histamine and h1, h2 and h3 central receptors on food intake in broiler chickenswas investigated. for this purpose, a probe was used to manipulate the concentration of endogenoushistamine by intracerebroventricular (icv) injection of thioperamide, an h3 receptor antagonist, and r-α-methylhistamine, an h3 receptor agonist and subsequently the effects of brain histaminergic...

efficient use of natural and biological cycles such as nitrogen fixation by legumes may stimulate yield of non-legumes crops in an intercropped system. in order to evaluate spring barley (h) and annual alfalfa (m) intercropping, a study was conducted in the research field of university of tehran (located in karaj) during 2009-2010 growing season. in this research, a randomized complete block de...

The interactions between H1 and H2, the two polypeptides comprising the human asialoglycoprotein receptor (ASGP-R), were investigated by immunofluorescence and lateral mobility measurements combined with antibody-mediated cross-linking and immobilization. Immunofluorescence microscopy revealed two ASGP-R populations on the cell surface, one homogeneously distributed and the other in micropatche...

Let h1, · · · , hn be positive integers. We study new sums m(h1, · · · , hn) = h1−1 ∑ r1=0 · · · hn−1 ∑ rn=0 min { r1 h1 , · · · , rn hn } and M(h1, · · · , hn) = h1−1 ∑ r1=0 · · · hn−1 ∑ rn=0 max { r1 h1 , · · · , rn hn } , the first of which times h1 · · ·hn is the number of lattice points in a pyramid of dimension n + 1. We show that m(h1, · · · , hn) (h1 − 1) · · · (hn − 1) = 1 + ∑ ∅6 =I⊆{1...

Fundamentals of Wireless Communications Homework 1 Solutions Handout date: April 1, 2014 Problem 1 Identification of LTV Systems 1. Suppose x stably identifiesQ. ForH1, H2 ∈ QwithH1x = H2xwe have 0 = H1x−H2x = (H1 −H2)x sinceH1, H2 are linear operators. Moreover,H1 −H2 ∈ Q. Since x stably identifiesQ, α‖H1 −H2‖H ≤ ‖(H1 −H2)x‖ = 0 with α > 0, which implies thatH1 −H2 = 0, i.e.,H1 = H2. 2. We sta...
