Diaquabis(picolinato N-oxide-κ2 O,O′)zinc(II)
In the title compound, [Zn(C6H4NO3)2(H2O)2], the Zn atom is located on a centre of inversion and shows a distorted octahedral coordination geometry. Two aqua ligands occupy the axial positions and four O atoms of the two chelating picolinic acid N-oxide ligands are located in the equatorial plane. Intermolecular hydrogen bonds between aqua ligands and organic ligands link molecules into a two-dimensional arrangement
Ethyl 4-[(4-chlorophenoxy)methyl]-2-(4-nitrophenyl)-1,3-thiazole-5-carboxylate
The title compound, C19H15ClN2O5S, contains two molecules (A and B) in the asymmetric unit. In molecule A, the dihedral angles between the thiazole ring and the pendant chlorobenzene and nitrobenzene rings are 72.14 (15) and 3.03 (15)°, respectively. The corresponding angles for molecule B are 45.56 (16) and 1.51 (14)°, respectively. In the crystal, both molecules form inversion dimers linked by pairs of weak C—H⋯O interactions
3-Bromo-1-(3-chloropyridin-2-yl)-N-(4-ethoxyphenyl)-1H-pyrazole-5-carboxamide
In the title compound, C17H14BrClN4O2, the pyrazole ring is almost coplanar with the benzene ring [dihedral angle = 0.5 (2)°], whereas the pyrazole ring is close to perpendicular to the 3-chloropyridine ring [dihedral angle = 73.7 (2)°]. An intramolecular C—H⋯O hydrogen bond occurs. The dominant interaction in the crystal packing is an N—H⋯N hydrogen bond, which generates a chain along the c axis. Weak intermolecular C—H⋯O and C—H⋯N contacts are also observe

Corrigendum to Acta Cryst. (2010), E66, o2004
Methyl 3-(cyclopropylmethoxy)-4-hydroxybenzoate
In the title compound, C12H14O4, the dihedral angle between the benzene ring and the cyclopropyl ring is 60.3 (4)°. In the crystal structure, molecules are linked by intermolecular O—H⋯O hydrogen bonds into chains running parallel to [101]
IT USAGE BEHAVIOR OF MEDICAL PERSONNEL: AN EMPIRICAL STUDY BASED ON THE THEORY OF PLANNED BEHAVIOR
Digitalization of regional public health information is an irreversible trend in the course of China\u27s social development. This is also one of the key tasks to reform China\u27s medicine and public health system. To learn more about the influence of using information technology for medical personnel and hospital performance, this study reviews in the personal perspective to know more about the sustainable action of using IT in hospitals based on the Theory of Planned Bahavior. We proposed a research model which expanded TPB and tested it based on 278 valid data collected from employees in a large-scale hospital in Anhui Province, East China. The results of study reveal: 1.We verified TPB in the Chinese context and found that attitude and subjective norm not only have a directly influence on behavioral intention, but also can influence the use behavior.2.The habit of using IT of medical personnel has a directly influence on the attitude of using IT, and it also has significant influence on the behavioral intention. Our research model discovered the relationship between subjective factors of IT users’ and their behaviour. The founding of this study not only can provide references regarding the direction of public hospitals reform in China for decision makers of hospitals, but also is very helpful for management teams in hospitals to adopt more rational management measures for better IT use among medical personnel, and better hospital performance
Methyl 3,4-bis(cyclopropylmethoxy)benzoate
The title compound, C16H20O4, was obtained unintentionally as the byproduct of an attempted synthesis of methyl 3-(cyclopropylmethoxy)-4-hydroxybenzoate. In the crystal, the molecules are linked by intermolecular C—H⋯O interactions
Letter Ruling 00-15: The Meaning of "Reasonable Transportation Charges"
The effect of plant population density (PPD) and root-induced leaf cytokinin on the compensatory growth of potted corn seedlings during post-drought rewatering was investigated. The study design comprised four treatments: (1) wetness with low PPD, (2) wetness with high PPD, (3) rewatering with low PPD, and (4) rewatering with high PPD. Results showed that drought stress restrained the growth of corns. By contrast, rewatering enhanced the net photosynthetic rate and growth of corns. During the 8 days of rewatering, compensatory growth during post-drought rewatering occurred in corns with high PPD; however, such compensatory growth did not occur in corns with low PPD. Zeatin riboside concentrations in leaves and xylem saps were significantly higher under rewatering treatment than those under wet treatment. High leaf cytokinin concentration accelerated corn growth. The coefficients of variation and Gini-coefficient of wet treatment were significantly higher than those of rewatering treatment under high PPD, demonstrating that intense intraspecific competition occurred in the wet treatment. Extreme intraspecific competition negatively affected net photosynthetic rate. In brief, the interactions between root-induced leaf cytokinin and weak intraspecific competition promoted the compensatory growth under high PPD
Manipulating Multiple Order Parameters via Oxygen Vacancies: The case of Eu0.5Ba0.5TiO3-{\delta}
Controlling functionalities, such as magnetism or ferroelectricity, by means
of oxygen vacancies (VO) is a key issue for the future development of
transition metal oxides. Progress in this field is currently addressed through
VO variations and their impact on mainly one order parameter. Here we reveal a
new mechanism for tuning both magnetism and ferroelectricity simultaneously by
using VO. Combined experimental and density-functional theory studies of
Eu0.5Ba0.5TiO3-{\delta}, we demonstrate that oxygen vacancies create Ti3+ 3d1
defect states, mediating the ferromagnetic coupling between the localized Eu
4f7 spins, and increase an off-center displacement of Ti ions, enhancing the
ferroelectric Curie temperature. The dual function of Ti sites also promises a
magnetoelectric coupling in the Eu0.5Ba0.5TiO3-{\delta}.Comment: Accepted by Physical Review B, 201
