Isomeric oligosaccharides and isomeric glycopeptides are sometimes difficult to separate on normal-phase (NP) and reversed-phase (RP) columns. A zwitterionic type of hydrophilic-interaction chromatography column with sulfobetaine groups (called ZIC-HILIC column) was first applied to the separation of 2-aminopyridine derivatized (PA) N-glycans and tryptic peptides of human serum immunoglobulin G...

the synthesis of heat integrated multi-component distillation systems is complex due to its huge search space for structural combination and optimization computation. to provide a systematic approach and tools for the synthesis design of distillation systems, a new method for modeling heat integrated columns is presented, and the operating cost objective function is minimized by improved harmon...

Concrete filled tube (CFT) columns have been used as primary axial load-carrying members in high-rise building especially in seismic zones. The structural member has become popular as it has a number of distinct advantages over an equivalent steel, reinforced concrete, or steel-reinforce concrete structural member. This paper is intended to presents numerical modeling of elliptical concrete-fil...

As part of a project to harvest semi-structured data from web tables, we describe an approach to extract an abstract representation of the column-header categories based on a context-free grammar for linear strings. The column-header structure is generally an XY-tessellation. The grammar provides a compact representation of infinitely many structural variations possible within column headers. B...

An Actinomycete, strain K-128, which was isolated from soil, formed a transfer product when the strain was cultured in a medium containing both stevioside and curdlan. The transfer product in culture broth was separated by DIAION HP-20 column and TOYOPEARL HW-40F column chromatographies. From structural studies, the transfer product was identified as C13-O-beta-6(2)-beta-glucosylsophorosyl-C19-...

In this paper, experimental testing and numerical analysis were used to investigate the effect of tube thickness on the face bending for concrete filled hollow sections connected to other structural members using Extended Hollobolts. Six samples were tested experimentally by applying pull-out load on the bolts. These samples were designed to fail by column face bending. The main variable in all...

Atomic contact potentials are derived by statistical analysis of atomic surface contact areas versus atom type in a database of non-homologous protein structures. The atomic environment is characterized by the surface area accessible to solvent and the surface of contacts with polar and non-polar atoms. Four types of atoms are considered, namely neutral polar atoms from protein backbones and fr...

The person’s way of thinking has a limit. There is a possibility that the better design pattern exists outside of their own ideas. In recent years, complicated structural analysis became possible by performance improvement of computer. The free structure forms which are not constrained by columns and girders became possible. The purpose of this study is the construction of the idea support syst...
