In these notes, we will be mainly focussing on the proof of the so-called ASM-DPP conjecture of Mills, Robbins and Rumsey [22] which relates refined enumerations of Alternating Sign Matrices (ASM) and Descending Plane Partitions (DPP). ASMs were introduced by Mills, Robbins and Rumsey [24] in their study of Dodgsons condensation algorithm for the evaluation of determinants. DPPs were introduced...
this research was undertaken to evaluate and determine the risk of gas fluids and leakage of persian gulf star refinery on the environment in bandar abbas. through collection and compilation of research findings, we attempted to identify and work on factors leading to environmental risks. the risk factors were identified by hazop team and the risk score was calculated by multiplying the probabi...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
in this research work, we report a simple method called reflux condensation method for synthesizing co3o4 nanoparticles using cheap chemicals such as, cobalt acetate (precursor salt), sodium monododecyl sulphate - sds (surfactant) and n, n - dimethylformamide - dmf (solvent). the prepared materials were heat treated at 200, 400, 600 and 800 oc for each 2 h to get phase pure product. the calcine...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
In this paper we will present a new method to calculate determinants of square matrices. The method is based on the Chio-Dodgson's condensation formula and our approach automatically affects in reducing the order of determinants by two. Also, using the Chio's condensation method we present an inductive proof of Dodgson's determinantal identity.

AIMS To present background, principles, and procedures for a strategy for qualitative analysis called systematic text condensation and discuss this approach compared with related strategies. METHODS Giorgi's psychological phenomenological analysis is the point of departure and inspiration for systematic text condensation. The basic elements of Giorgi's method and the elaboration of these in s...
