The present study investigated the impact of planting spacing on tomato crop growth, water productivity, and fruit quality under different regimes. Thus, a field experiment was conducted using randomized complete block design in factorial arrangement treatments. plants were grown at three patterns: 30 cm row-to-row spacing, 60 90 which marked as (G1), (G2), (G3), respectively. For each pattern,...

The concept of the D-brane probe provides the link between gauge theory and geometry. It has proven to be one of the most important ideas among recent developments in string theory, shedding new light on strong coupling gauge theory dualities, providing a physical interpretation of previously obscure algebraic-geometric constructions, and resulting in examples of the AdS/CFT correspondence with...

The equations of motion of the massless sector of the two dimensional string theory, obtained by compactifying the heterotic string theory on an eight dimensional torus, is known to have an affine o(8, 24) symmetry algebra generating an O(8, 24) loop group. In this paper we study how various known discrete Sand T duality symmetries of the theory are embedded in this loop group. This allows us t...

Brassinosteroid as one of steroid hormones has an integral role in controlling plants physiological process especially in response to biological and non-biological stress. This research has been done in Damghan Islamic Azad University Greenhouse. The influence of four concentrations of plant growth regulator -24, homobrassinolide with concentration of 0,10-10, 10-8,10-6 molar on null seedlings ...

In this paper, we prove that the connectivity and the edge connectivity of the lexicographic product of two graphs G1 and G2 are equal to κ1v2 and min{λ1v 2 2 , δ2 +δ1v2}, respectively, where δi, κi, λi and vi denote the minimum degree, the connectivity, the edge-connectivity and the number of vertices of Gi, respectively. We also obtain that the edge-connectivity of the direct product of K2 an...

DNA polymerase alpha-primase is known to be phosphorylated in human and yeast cells in a cell cycle-dependent manner on the p180 and p68 subunits. Here we show that phosphorylation of purified human DNA polymerase alpha-primase by purified cyclin A/cdk2 in vitro reduced its ability to initiate simian virus 40 (SV40) DNA replication in vitro, while phosphorylation by cyclin E/cdk2 stimulated its...

for two given graphs g1 and g2, the ramseynumber r(g1,g2) is the smallest integer n such that for anygraph g of order n, either $g$ contains g1 or the complementof g contains g2. let tn denote a tree of order n andwm a wheel of order m+1. to the best of our knowledge, only r(tn,wm) with small wheels are known.in this paper, we show that r(tn,wm)=3n-2 for odd m with n>756m^{10}.

We classify biharmonic and harmonic homomorphisms f:(G,g1)⟶(G,g2) where G is a connected simply three-dimensional unimodular Lie group g1 g2 are left invariant Riemannian metrics.

Due to their unique properties, Anticancer dendrimer-based drugs have been displaying promising results in both in vitro and in vivo in the treatment of cancerous cells, as compared to the traditional polymers. In this report, two conjugates (G1+Pt and G2+Pt) of cisplatin [cis-diaminedichloroplatinum; (CDDP)] with two generations (G1, G2) of a biocompatible anionic dendrimer were prepared in an...

We motivate and summarize our analysis of hep-th/0610276 in which we consider D7-brane probe embeddings in the Polchinski-Strassler background with N = 2 supersymmetry. The corresponding dual gauge theory is given by the N = 2 theory with fundamental matter. Based on a talk given by C. Sieg at the RTN Workshop 2006, Napoli. ∗[email protected], [email protected], [email protected], [email protected]...
