We have investigated the probing beam transmitance due to the photon-induced anisotropy effect in the bacteriorhodopsin/polymer composite film(bR/PC film) by using the probing-pumping beam method under different laser wavelengths. By using a theoretical simulation, we give the characteristics of the birefringence Δn and the dichroism ΔD for various wavelengths of the probing and the pumping beams.
Partial dehulling increases the energy content and nutrient digestibility of barley in growing pigs

Objective: The hull attached to the barley kernel can be mechanically removed thus reducing the fiber content of the barley. This experiment was carried out to evaluate the effects of partial dehulling on the nutrient digestibility as well as the digestible energy (DE) and metabolizable energy (ME) content of barley in pigs. Methods: Two hulled barley samples (high fiber barley [HF] and low fiber barley [LF]) with either high or low fiber contents were obtained from the Hubei and Jiangsu Provinces of China. A portion of the two barleys was mechanically dehulled (dehulled high fiber barley [DHF] and dehulled low fiber barley [DLF]). Thirty barrows (initial BW = 31.5±3.2 kg) were assigned to one of five diets in a randomized complete block design. The five diets consisted of 96.9% corn, HF, LF, DHF, or DLF supplemented with 3.1% minerals and vitamins. Each diet was fed to six barrows housed in individual metabolism crates for a 10-d acclimation period followed by a 5-day total but separate collection of feces and urine. Results: The daily loss of gross energy (GE) in feces was lower (p<0.01) for pigs fed DHF than for those fed HF. The daily N intake and fecal N loss were lowest (p<0.01) for pigs fed the corn diet. The DE and ME as well as the apparent total tract digestibility (ATTD) of dry matter, GE, organic matter, neutral detergent fiber (NDF) and acid detergent fiber (ADF) of DHF or DLF were higher (p<0.01) than the values in HF and LF, respectively while the values except the ATTD of NDF and ADF in DLF were higher (p<0.01) than the values in DHF and were comparable to corn. Conclusion: The DE and ME contents as well as the ATTD of nutrients in both DHF and DLF barley were improved compared with the HF and LF barley. Moreover, the nutritive value of DLF barley was comparable to the yellow-dent corn used in the study.
Bioremediation of Pb-Contaminated Soil Based on Microbially Induced Calcite Precipitation

To remediate lead (Pb)-contaminated soils, it is proposed that microbially induced calcite precipitation (MICP) would provide the best alternative to other remediation technologies. In this study, Pb bioremediation in soils was investigated using the calcite-precipitating bacterium Kocuria flava. Results indicate that the Pb is primarily associated with the carbonate fraction in bioremediated soil samples. The bioavailability of Pb in contaminated soil was reduced so that the potential stress of Pb was alleviated. This research provides insight into the geochemistry occurring in the MICP-based Pb-remediated soils, which will help in remediation decisions.

The α-gliadins from Crithopsis delileana (Schult) Roshev (2n=2x=14, KK) were investigated by Acid polyacrylamide gel electrophoresis (A-PAGE) analysis. It was indicated that the electrophoresis mobility of gliadins from C.delileana had obvious difference with those from common wheat in α, γand ω region. Using primers designed from published sequences of α-gliadin genes, three α-gliadin genes were isolated from C. delileana, which were designated as gli-ka1,gli-ka2 and gli-ka3, respectively. Two in-frame stop codons were found in the coding sequences of gli-ka3, indicating that gli-ka3 could be a pseudogene. The gli-ka2 was a gliadin with an odd number of cysteines, resulting from a non-synonymous mutation. This change might lead to the interactive behavior of gli-ka2. Three α-gliadin genes of C. delileana had the similar but not identical primary structures to the corresponding gene sequences from other wheat related species. By the alignment of α-gliadin genes from Triticeae,phylogenetic analysis indicated that three α-gliadin genes of C. delileana clustered together with all α-gliadin genes from Ee genome of Lophopyrum elongatum by an interior paralleled branch.
