An experiment was conducted to determine the differences in body weight (BW), feed intake (FI) and some egg production traits of two strains of layer chickens (Isa Brown and Nera Black) and correlate the relationships between the tested traits. The study commenced when the layers were 26 weeks old and a total of 200 (100 of each strain) were used. Sixty fresh eggs (30 from each strain) were col...

Commercial corn breeding and trait integration have changed modern corn production. In recent years, technology advances for control of insects, weeds, and diseases have improved corn yield levels significantly. Conventional breeding continues to be the foundation of new inbreds (parent lines) for hybrid development. Another method of inbred development is called doubled haploids. This methodol...

56 ground motions of the bedrock and surface are selected from 28 stiff sites ( site class I and site classⅡ) of the KiK-net station．The peak acceleration, response spectra and shear strain of actual hard sites are calculated by using SHAKE2000 and LSSRLI-1. The similarities and differences between SHAKE2000 and LSSRLI-1 and their differences from measured records are analyzed. It provides a ba...
