Fusarins G1/G2 (1/2) and G3/G4 (3/4), two sets of interesting examples of diastereoisomers with substantially identical NMR data, were discovered from natural products. The reason was discussed and the generally applicable determinant conditions were proposed. The minimum interval for stereoclusters to be entirely segregated was also discussed.

We prove that, for every n-vertex graph G, the treewidth of G plus the treewidth of the complement of G is at least n − 2. This bound is tight. © 2012 Gwenaël Joret and David R. Wood. Published by Elsevier Ltd. All rights reserved. Nordhaus–Gaddum-type theorems establish bounds on f (G) + f (G) for some graph parameter f , where G is the complement of a graph G. The literature has numerous exam...

LetG = (V,E) be a graph with a fixed orientation and let A be an abelian group. Let F (G,A) denote the set of all functions from E(G) to A. The graph G is A-connected if for any function f̄ ∈ F (G,A), there exists an A-flow f such that f(e) 6= f̄(e) for any e ∈ E(G). The graph G is A-colorable if for any function f ∈ F (G,A), there exists a function c : V (G) → A such that for any arc e = (u, v) ...

Apart from strengthening crew protective capability gunfire, the hull obliquity in a light armoured vehicle (LAV) affects its weight and comfortable occupancy. Thus, it requires critical design analysis for obliqued hull. The study aims to present optimal of an structure ensure occupancy along with minimum attainable higher protection gunfire. Three geometric models (G1, G2, G3) were investigat...

purpose: the aim of this study was to test the in vitro sensitivity of lymphocytes of patients with head and neck cancer against gamma irradiation and also to find out if the frequencies of chromosomal aberrations correlate with side effects of radiotherapy. patients and methods : peripheral blood of 101 patients with head and neck cancer was collected before the onset of radiotherapy, cultured...

introduction: an effective vaccine against hcv infection is not available. the non-structural protein 3 (ns3) of the virus as an important immunogenic candidate has been utilized in various modules. nanostructured polymers have been recently used for efficient vaccine and drug delivery. the aim of the current study was the synthesis of rns3-g2 conjugate and preliminary evaluation of its immunog...

Objective(s) Two new adjuvants from natural animal lipids (G2) and bacterial polysaccharide extracts (PC) were previously prepared by our group and showed a reduction in tracheal responsiveness. The aim of this study was to evaluate the preventive effect of recently introduced natural products (G2 and PC) on the development of asthma. Materials and Methods Asthma was induced using a standard...

The moduli space of complex structures on a compact Riemann surface of genus 1 or ≥ 2 can be identified with the deformation space of Riemannian metrics of constant curvature 0 or −1, while the latter definition natually gives rise to the Weil-Peterson metric. Let M be a compact manifold of domension 7 with an integrable G2 structure, i.e., a differential 3-form φ that satisfies dφ = 0, and d ∗...
