Dairy cow were inseminated with routine semen and sexing semen separated by flow cytometry in this experiment and the results showed that the pregnant rates of the treatment group (sexing semen) and the control group (routine semen) were 54.81%(74/135) and 60.61% (40/66) respectively,and there was no significant difference between them (P＞0.05).
Experimental results indicate that SnO2 structure,crystallization are obviously influenced by behaviors of doped Al2O3 and can decrease crystallization temperature of SnO2,and the composites of Al2O3/SnO2 possess considerable infrared absorption at 400～1 000 cm-1.
Its common tendency is to think that the theoretical construction of translation should be aimed at the transcendental inquiries of "translation of translation",stressing the split of translation theory from the phenomena translation so as to approach the "truth-value" and establish an everlasting fulcrum for translation study.
Equal dimension GM(1,1)? polynomial fitting are all applied for the prediction for the total amount of coal in this paper. The results show that equal dimension GM(1,1) is applicable and its precision is better than the traditional method of polynomial fitting and ordinary GM(1,1).
The location of CT(myelography),EMG,Clinical signs and Operation that are completely same is 56.6%,the location of EMG,clinical signs,operation that are completely same is 60.6%,and the three item aren't completely same is 39.4%.
Newcastle vanished vaccine was produced from hatching eggs of three different maternal antibody,the average ratio of defunct embryo was 7.49% in maternal antibody of 1～3 log2,hematic coagulating rate was 1:1 024,EID50/(0.1mL) was 108.97,its effect was better than that of high maternal antibody.
According to the statistical test,all of these three kinds of models fitted the experimental data quite well,and statistical analysis showed that the linear model was the best,whether the remnant food in stomach was expressed by wet weight or dry weight. When the remnant food in stomach was expressed by wet weight,the model was Y=92.93-3.33 t(R2=0.94,P<0.001);
The purpose of this note is to prove, as Lusztig stated, that the Euler characteristic of the variety of Iwahori subalgebras containing a certain nil-elliptic elementnt istcl wherel is the rank of the associated finite type Lie algebra.
In the present paper we study the remaing nontrivial case, that of a negative central charge-N.
In this note we present a very simple method of proving that some hyperbolic manifoldsM have finite sheeted covers with positive first Betti number.
In all these cases we actually show that Γ=π1(M) has a finite index subgroup which is mapped onto a nonabelian free group.
In the case of 4-dimensional anticommutative algebras a construction is given that links the associated cubic surface and the 27 lines on it with the structure of subalgebras of the algebra.
