抓人性化管理 构筑和谐企业

人性化管理是基于人性特征而实施管理的一种模式,其本质是尊重人的本性、满足人的需求、激励人的热情、调动人的积极性和发挥人的创造性,实现组织和组织成员的共同发展。改革开放以来,人性化管理的思想和方法逐步被轮胎企业管理者所重视,并且不断实施人性化管理。人性化管理逐渐成为轮胎企业培育核心竞争力最为重要的管理模式之一。     

芦荟对嗜酸乳杆菌酸乳发酵性能的影响

选择嗜酸乳杆菌、嗜热链球菌为发酵菌种 ,研究芦荟全叶汁对酸乳发酵过程中的滴定酸度、pH值、黏度及感官性状等的影响。试验发现 ,芦荟的添加对嗜酸乳杆菌和嗜热链球菌的生长影响不大 ,但影响酸乳的凝固性、pH值、黏度 ,进而影响品质等。试验结果表明 ,当芦荟添加量为 10 %左右时 ,成熟后的酸乳中La可达 10 9,产品的品质最佳。     

Reducing the Influence of the Thermally Induced Reactions on the Determination of Aroma-Active Compounds in Soy Sauce Using SDE and GC-MS/O

A method based on simultaneous distillation extraction (SDE) coupled with gas chromatography–mass spectrometry/olfactometry (GC-MS/O) was developed for the analysis of volatile profiles in soy sauce. Its optimum operating conditions were as follows: 100 mL soy sauce plus 100 mL saturated brine; 2 h extraction using 50 mL dichloromethane. Eighty-eight volatile compounds were identified. Of these, 26 aroma-active compounds were detected by GC-O including 3-(methylthio)propanal, 2-methoxy-4-vinylphenol, 2-methoxyphenol, 2-methylbutanoic acid, 2,3-butanedione, phenylacetaldehyde, 2-ethyl-6-methylpyrazine, 3-methylbutanal, 2-methylbutanal, 3-methyl-1-butanol, and 2-methyl-1-butanol (which occurred at a high odor intensity in both high-salt liquid-state fermentation soy sauce (HLFSS) and low-salt solid-state fermentation soy sauce (LSFSS). SDE analysis of the odorless soy sauce indicated 12 volatiles (mainly Strecker aldehydes and α-dicarbonyl compounds). Thus, the proportions of these compounds (1.94–54.07 %) shown in previous GC-MS results could result from thermal degradation of non-volatile compounds in soy sauce. Especially, the contribution of 3-methylbutanal, 2-methylbutanal, phenylacetaldehyde, 3-(methylthio)propanal, and 2,3-butanedione to the aroma of soy sauce could be overestimated by conventional SDE-GC-O. With a full consideration of such limitations, this study will improve the application of SDE on aroma analysis of complex food matrix.     

Dieulafoy病致消化道大出血的介入治疗

目的探讨介入治疗Dieulafoy病所致的消化道大出血的效果及应用价值。方法１０例Dieulafoy病所致急性消化道大出血患者常规行腹腔动脉和胃左动脉造影,发现有胃左动脉出血征象和（或）血管异常者８例,６例使用明胶海绵栓塞,２例血管瘤样扩张者使用明胶海绵＋弹簧钢圈栓塞;另２例无明显出血征象者中１例给予垂体后叶素灌注,另１例未予介入治疗。结果本组病例术中均无严重并发症。栓塞的８例患者中,１例明胶海绵栓塞术后第３天再呕血,后行外科手术治疗,其余７例均未再出血;１例垂体后叶素灌注患者１周后症状消失出院。结论介入疗法安全、快捷、见效快,是急诊处理Dieulafoy病所致消化道大出血较为理想的治疗手段。

马尾松CTMP过氧化氢-TAED活化体系的漂白性能研究

本实验以马尾松CTMP为原料进行了H2O2与TAED组成的活化体系漂白性能的研究。研究结果表明,H2O2-TAED活化体系漂白反应可在较低温度和较短时间内完成,适宜的漂白温度为55℃,漂白时间为60min;当过氧化氢用量为6%时,浆料白度增值可达24.0%ISO;此漂白体系可使漂后浆的抗张指数、撕裂指数和耐破指数分别提高34%、28%和20%。     

Identification and characterization of novel promoters for recombinant protein production in yeast Pichia pastoris

Pichia pastoris expression system has been widely used in recombinant protein production. So far the majority of heterologous proteins are expressed by methanol inducible promoter P_AOX1 and constitutive promoter P_GAP. The use of other promoters is rather limited. Here we selected 16 potentially efficient and regulatory promoter candidates based on the RNA‐seq and RNA folding free energy ΔG data. GFP and recombinant amylase were inserted after these promoters to reveal their strength and efficiency under different carbon sources and culture scales. Two novel promoters were successfully identified and could possibly be applied in recombinant protein expression: the methanol‐inducible promoter P₀₅₄₇ and the constitutive promoter P₀₄₇₂.
