thirty nine novel 1,2,3,4-tetrahydropyrimidinone (thione)s were subjected to conformational studies. density functional theory at b3lyp/6-31 g* was performed as the computational method of high accuracy. important dihedral angles and bond lengths were investigated and the values obtained were explainable. results of this work confirm a twisted boat tetrahydropyrimidine ring conformation with an...

The surface of a biomaterial interacts with the body fluid upon implantation in the human body. The biocompatibility of a material is strongly influenced by the adsorption of proteins onto the surface. Titanium is frequently used as a biomaterial for implants in orthopedics and cardiovascular devices. Understanding the biocompatibility is very important to improve implants. The surface chemistr...

The Cover Feature illustrates the pathways undergone by ditellurocines from solid state (represented stones) to solution water cascade). Once ditellurocine crystals/stones roll down in cascade, metamorphosis occurs, cubic-like arrangement a caterpillar (less stable chair conformation) then lying butterfly (transition state) and flying (more boat conformation).

The objective of this study was to explore the effect dam body conformations on birth traits including stillbirth, dystocia, gestation length and weight Chinese Holstein calves provide a reference for improving cow reproductive performance. We collected phenotype data 20 conformation cows analyzed impact trait linear scores calf weight. feet angle, set rear legs, fore udder attachment height da...
