The beneficial effects on meat quality of adding vitamin E to diets have been extensively studied in cattle and lamb. However, how supplemental vit E affects the performance and meat quality of 'Tan' sheep has not been reported. Thirtyfive male lambs of 'Tan' sheep (20-30 d after weaning) with similar body weight were randomly divided into five groups of seven each to receive a basal diet plus five levels of vit E supplementation: 0 (control group, CG), 20, 100, 200, and 2000 IU d-1 lamb-1. The results showed: 1) no differences were observed in animal growth performance between CG and vit E treated groups (VG) (P > 0.05); 2) vit E supplementation levels over 200 IU d-1 lamb-1 dramatically suppressed subcutaneous fat deposition and similarly that above 100 IU d-1 lamb-1 considerably reduced drip loss and pH 24 h of Longissimus dorsi (LD) muscle in VG lambs compared to those of CG (P < 0.01), but with no significant effect on other carcass characteristics (P > 0.05); 3) although vit E supplementation generally did not affect the fatty acid composition of intramuscular lipids in LD muscle, the percentage of n-6 polyunsaturated fatty acids (PUFA) and the ratio of n-6/n-3 PUFA were significantly enhanced (P < 0.05) and an increasing tendency (P < 0.1) for both total PUFA proportion and the ratio of PUFA/saturated fatty acids (SFA) was also observed in 'Tan' sheep lambs treated with vit E. In conclusion, vit E supplementation of male 'Tan' sheep lambs did not influence growth performance, significantly reduced subcutaneous fat deposition, drip loss, pH 24 h and tended to improve fatty acid profile of LD muscle.

Two 3-nitro-phthalate dianions bridge two water-coordinated 2,2′-bipyridine-chelated CuII atoms about a center of inversion to generate the title dinuclear compound, [Cu2(C8H 3NO6)2(C10H8N 2)2(H2O)2]·2H2O. The geometry of the CuII atom is a distorted square pyramid. Adjacent mol-ecules are linked through the coordinated and solvent water mol-ecules to form a linear ribbon running along the a axis of the monoclinic unit cell. Source

The shift easily occurs in the mold making and mold assembling during the production of high-chrome cast ball of ball mill by stack casting, which make rejection rate and defective rate higher. To guarantee the upper and lower mold centering, reduce the shift quantity farthest, and eliminate the rejection and defective rate, effective measures that make mold centering were put forward. The high costs of machining were reduced in the design of processing technology. The measures were successfully applied to the whole manufacture of tool equipment production of stack casting process for high-chrome cast ball. ©, 2015, Chinese Mechanical Engineering Society.

In order to develop a method for rapid detection of total potassium content in leaf of maize, electrical impedance measuring method was used to collect the electrical impedance parameter of the leaf tissue juice under different potassium levels, and the relationship between impedance value and total potassium content of the leaf were investigated. Using stepwise regression method to choose the sensitive frequency for the total potassium content, every regression model included two sensitive frequencies based on which the linear regression equation was the best with the correlation coefficient of 0.83 at least and root mean squared error of 0.16 at most for four growth periods respectively. Therefore, it was demonstrated that impedance value could be a predictor for maize leaf potassium content. Electrical impedance measuring technology could be an available method for potassium fertilizer recommendation in crop. Source

Message verification is important for information security, and the hash-based algorithm is a kind of implementation method. In this paper, we propose a circuit implementation scheme to realize message verification, which is based on SHA1, called HMAC-SHA1. In our scheme, the MD5 circuit module is reusable such that the circuit size is reduced and the processing speed is improved. Finally, we use VeriIogHDL to picture the circuit structure and implant it into FPGA to do experiments. © 2016 IEEE. Source
