Abstract:
A part of the pyrazolo[1,5-a]pyridines as novel P13K
inhibitors. To build the quantitative structure activity
relationships (QSAR) between the molecular structures
and the inhibitory activities of 16 compounds, and to
further discuss the structural factors that influence
activity of compounds. The topological, constitutional,
geometrical, electrostatic and quantum-chemical
descriptors of 16 compounds were calculated by CODESSA,
and these descriptors were preselected with the
heuristic method (HM). As a result, the five descriptor
linear model was developed to describe the relationship. |

Abstract:
It collects environmental pollution, environmental
governance index data of green logistics development
evaluation index system in Beijing. It gets the
qualitative index data by questionnaire. According
the principle of comparability，it standardizes data.
Establish index evaluation grade using fuzzy
comprehensive evaluation method. The objective of
this study is to prepare data for the further study
of green Logistics comprehensive evaluation.

Abstract:Two
ultra cool different ions are considered as a unique
quantum mechanical system in a harmonic trap. The
properties of the system are investigated as a model of
laser Cooling fluorescence mass analysis. The energy
flow between the sample molecular ion and the atomic
probe ion through the Coulomb interaction is analyzed as
a process of Ferni resonant interaction of different
states of the system. Using first order perturbation
theory the translational energy efficiency between laser
cooling atomic ion and the sample molecular ion is
given, accordingly, signal strength distribution of mass
spectra relative to mass number of sample molecular ions
is discussed. |

Abstract:The
quarterly data of 2006-2013 premium income and GDP is
used in the paper, using the ADF test and cointegration
test and Granger causality test on the relationship
between the development of insurance and economic growth
in China by empirical analysis and test of the two. The
results show that in the sample interval, China
insurance development is the Granger cause of economic
growth, while promoting economic growth on the
development of insurance is not obvious. |
