Study on Gelatination and Micellization of Amphiphilic Copolymers;

This simple and general process is environment-friendly, and the products obtained are amphiphilic and dispersible well in most of the polar and nonpolar solvents.

In this paper, a series of PEG macroinitiators were prepared by the reaction between monodisperse PEG and 2-bromoisobutyryl bromide, and the synthesis of the ABA-type amphiphilic triblock copolymers with the photo-sensitive property (PFM (1)C-b-PEG-b-PFM (1)C) via atom transfer radical polymerization with CuCl/N, N, N′, N″, N″-pentamethyldiethylenetriamine (PMDETA) complex as the cat.

Especially parents have primary effect in children s sports participancy.

Study on Nutritional Quality Traits of Carrot Hybrids in Relation to their Parental Varieties;

The paper reviews parental influence on children s motivation of sport participation from three aspects: 1) parents behavior; 2) parents emotion and attitude; 3) parents belief in sports.

The influence of hydrophilic segment chain length of the polyethylene (PEG) on contact angle,water-vapor permeability,water-absorbing capacity and mechanical properties of polyurethane film was investigated.

The synthesis of the polyester-polyol poly-segment copolymers was studied , and a copolymer was synthesized and theoretically evaluated for its co-crystalline and hydrophilic segments and its structural characteristics by the modern analytic means such as IR, GPC and DSC.

Effect of Disproportional Expression of the Aberrant and Correct Kappa Chain Transcripts on Antibody Secretion of Sp2/0 Derived-CEA and AFP Hybridomas and Expression of Cloned Anti-CEA ScFv-streptavidin Fusion Protein;

To obtain the anti-transferrin receptor scFv and streptavidin(SA) recombinant fusion proteins which were high-efficiently and solubly expressed in E.

Objective To study the purification,refolding and bioactivity of streptavidin-tagged human tumor necrosis factor-α(SA-TNF-α) bi-functional fusion protein.
