In this paper, 1-lump solution and 2-lump of a (2 + 1)-dimensional Sawada-Kotera-like equation are obtained by means the Hirota’s bilinear method long wave limit method. The propagation orbits, velocities collisions among waves analyzed. By setting parameter values, dynamic characteristics solutions shown in 3D density plots. These conclusions enrich dynamical theory higher-dimensional nonlinea...

Cis-Diamminedichloroplatinum II (CDDP) has been recognized as one of the most active drugs against malignant tumours including ovarian cancer. However, CDDP is a toxic drug causing emesis, renal failure, hearing loss, neuropathy and anaemia. In view of these toxicities many investigators have attempted to develop new platinum analogues which retain anti-tumour activity with less toxicity. Among...

Let Pt and C` denote a path on t vertices and a cycle on ` vertices, respectively. In this paper we study the k-coloring problem for (Pt, C`)-free graphs. Maffray and Morel, and Bruce, Hoang and Sawada, have proved that 3-colorability of P5-free graphs has a finite forbidden induced subgraphs characterization, while Hoang, Moore, Recoskie, Sawada, and Vatshelle have shown that k-colorability of...

Abstract In this paper, the KdV-Sawada-Kotera-Ramani(KdVSKR) equation in various dimensions are studied. The bilinear form of (1+1)-dimensional and (2+1)-dimensional KdVSKR obtained by independent transformation. Based on Hirota method, we constructed new interaction solutions studying unknown nonlinear differential equations for corresponding parameters. Three dimensional plots, density plots ...

Phospholipidosis (PLD) is characterized by an intracellular accumulation of phospholipids in lysosomes and the concurrent development of concentric lamellar bodies. Recently, H. Sawada et al. (2005, Toxicol. Sci. 83, 282-292) identified 17 genes as potential biomarkers of PLD in HepG2 cells. The present study was undertaken to determine if this set of genes measured by quantitative PCR could be...
