The Synthesis of Planar Four-Bar Linkage for Mixed Motion and Function Generation.

The synthesis of four-bar linkage has been extensively researched, but for a long time, the problem of motion generation, path generation, and function generation have been studied separately, and their integration has not drawn much attention. This paper presents a numerical synthesis procedure for four-bar linkage that combines motion generation and function generation. The procedure is divided into two categories which are named as dependent combination and independent combination.

Magnetic hardening of Nd-Ce-Fe-B films with high Ce concentration.

Partial substitution of Ce in Nd-Fe-B magnets is a feasible way to cope with the crisis of Nd and Dy in Nd-Fe-B production and reduce the cost of Nd-Fe-B magnets. In the present paper, the Nd-Ce-Fe-B films with high performance have been successfully fabricated by using an ultra-high vacuum (UHV) magnetron sputtering system. High magnetic performance with a ceorcivity of 13.

Synthesis of fluorescent and low cytotoxicity phenol formaldehyde resin (PFR)@Ag composites for cell imaging and antibacterial activity.

Ag nanoparticles (NPs) were loaded onto the surface of phenol formaldehyde resin (PFR) NPs without any reducing agent. The as-synthesized PFR@Ag composites have low cytotoxicity, which makes them promising antibacterial agents. Furthermore, the good fluorescence of PFR could be used for cell imaging.

[Identification of major components of Xingsusan decoction by HPLC-HR-TOF/MS].

Objective: The major components of Xingsusan decoction were studied by HPLC-HR-TOF-MS.

Methods: A Welchrom- C18 column (4.6 mm x 250 mm, 5 μm) was used at a flow rate of 1.

[Postoperative complications of advanced schistosomiasis portal hypertension].

The data of 72 cases of advanced schistosomiasis portal hypertension patients who received surgical treatment were retrospectively analyzed in the Fifth People's Hospital of Changde City from January, 1999 to January, 2011. Postoperative complications occurred in 17 cases, and the rate was 23.6%, including intra-abdominal bleeding in 2 cases, postoperative infection in 5 cases, recent upper gastrointestinal bleeding in 3 cases, massive ascites in 2 cases, persistent fever in 3 cases, and unusual increase of platelets and portal vein thrombosis in 2 cases.

Crystallographic structure at 1.6-A resolution of the human adenovirus proteinase in a covalent complex with its 11-amino-acid peptide cofactor: insights on a new fold.

The crystal structure of the human adenovirus proteinase (AVP), a cysteine proteinase covalently bound to its 11-amino-acid peptide cofactor pVIc, has been solved to 1.6-A resolution with a crystallographic R-factor of 0.136, R(free)=0.

Correlated alternative side chain conformations in the RNA-recognition motif of heterogeneous nuclear ribonucleoprotein A1.

The RNA-recognition motif (RRM) is a common and evolutionarily conserved RNA-binding module. Crystallographic and solution structural studies have shown that RRMs adopt a compact alpha/beta structure, in which four antiparallel beta-strands form the major RNA-binding surface. Conserved aromatic residues in the RRM are located on the surface of the beta-sheet and are important for RNA binding.
