Nine cases of metachronous multiple primary cancers;

Metachronous Metastases of Colorectal Cancer

RESULTS:There were 16 cases with synchronous BPBC (sBPBC) and 38 cases with metachronous BPBC (mBPBC).

Species diversity under effects of temporal heterogeneity of habitat destruction;

Mountain ecosystems in arid and semiarid regions are frequently characterized by significant spatial self-organization,and temporal heterogeneity of soil moisture maybe an important driver factor in the vegetation pattern formation and maintenance.

The new accounting rules regulate that the income tax accounting treatment should use the balance sheet debt law,establish the proper separation of accounting profit and taxable income,and define the concept of temporary differences, which are more integrated,more canonical and more suitable for the modern accounting theory and rules compared to the old ones.

It introduces the concept of temporary differences to measure differences.

It also introduces the concept of tax base to measure temporary differences.

Based on the observation datum of typical field,experiment study on the spatial and temporal variability of infiltration have been performed on a surface irrigation field during the growing period of winter wheat,the distribution characteristic of spatial and temporal variability of infiltration parameters were described,and the correlation between different parameters were analyzed.

The spatial and temporal variability of soil moisture under mulched drip irrigation of cotton fields can provide guideline for the soil moisture monitoring program.
