High pressure treatment of Swiss cheese slurries (I): Inactivation of selected microorganisms after treatment and during accelerated ripening

Cheese slurries, made from fresh Swiss cheese curd, were treated at 345 or 550 MPa for 10 or 30 minutes in an isostatic press at 25°C. The slurries were ripened at 30 °C for 0,3 and 5 days. The growths of coliforms, yeasts and molds, starter bacteria (Lactococci andStreptococci), non-starter lactic acid bacteria (Lactobacilli), and presumptive coagulase-positiveStaphylococcus were determined. An electronic nose was used to evaluate aroma development of the cheese slurries. Commercial Swiss cheeses with different ages were used as aroma references. The degree of inactivation of organisms was found to be a function of pressure intensity, exposure time, type of organism, and cheese slurry pH. In general, slurries treated at a higher pressure and with a longer exposure time showed a greater reduction in numbers and had less out-growth of organisms during ripening.Coliforms, yeasts and molds were completely inactivated at the pressures and time used. Starter bacteria appeared to be more resistant to being inactivated by high pressure treatment and had a greater out-growth rate thanLactobacilli andStaphylococci. Based on canonical analysis, nineteen samples for each batch were assigned to three groups. In general, higher intensity of pressure or longer exposure time caused less aroma development in the cheese slurries. When the cheese curd was incubated overnight prior to making the cheese slurries, stronger slurries with stronger aroma were observed. This study provided an explanation of the relative importance of relationships among high pressure treatment, starter bacteria, and aroma development during accelerated ripening.

如何有效实施绩效管理

如果你是一名企业高层管理或HR经理，作为绩效管理制度的策划和组织，是否有一天发现，公司例行的绩效考评不再像最初实施时那样起作用了，你感到考评流于形式，考评制度开始像过冬的青蛙一样进入休眠或半休眠状态，你会问自己，公司耗费资源进行绩效管理还有必要吗？如果不必要，用什么方法来衡量员工的工作成果和技能？如果必要，又如何让公司的绩效管理制度结束休眠而充满活力呢？如果你还不能很好地回答这些问题，就有必要重新加深对绩效管理工作的认识，克服和纠正低效的绩效管理行为，让你的绩效管理更加有效，不断焕发事业和组织的生命力。     

Solvent effects on infrared spectra of 2-Methyl-4,5-dimethoxy-3-oxo-2H-pyridizine: Part 2. Binary solvent systems

This research on the solvent effects of 2-methyl-4,5-dimethoxy-3-oxo-2H-pyridizine (MDOP) in binary solvent systems on the infrared spectra for MDOP in n-hexane/CHCl₃ mixture solvents showed that there were three forms of carbonyl stretching vibration band [ν(C=O)] of MPOP as the mole fraction of CHCl₃ in the binary solvents changes. In pure n-hexane solvent, the ν(C=O) of MDOP appeared at a relatively high wavenumber. With CHCl₃ added, the ν(C=O) shifted to lower wavenumbers. Two new bands were observed over a certain range of mixture solvent compositions. The origin of the bands was discussed in the terms of two kinds of hydrogen bond together with their individual dependence on mixture composition. Comparisons were drawn for the solvent sensitivities of ν(C=O) for propanone. Project supported by the Analysis and Measurement Foundation of Zhejiang Province, China.     

“璈”“云璈”的释义问题

权威辞书对"璈""云璈"的释义存在模糊、矛盾之处,这些问题也影响到了具体的注释活动。现有研究成果以及新的书证表明"璈""云璈"存在两个义项,一个是作为弦乐器,一个是作为打击乐器。当下具体注释活动中出现的问题,要求我们必须充分重视词义的历时分界。针对"璈""云璈"的个案研究,对辞书编纂工作也具有一定的参考价值。

多元智力理论视野下的课堂教学公平

霍华德·加德纳的多元智力理论,打破了传统的智力理论对个人发展的狭隘认识,为我们提供了一种新的个人发展模式,使我们能够从一个全新的角度来理解学生的发展;审视我们对学生的评价;为课堂教学的公平性提供了强有力的理论基础。     

我国高等学校师生关系的特点及治理

师生关系是高等学校中最基本的人际关系.当前我国高等学校师生关系赖以存在的基础和环境正在发生着深刻的变革.当前我国高等学校师生关系呈现的特征,既有其内在的规定性,又有其"时代特点"和"文化特色".高等学校师生关系具有复杂性、多维性、情境性和发展性特点.建立健全师生关系治理体系,统筹协调推进师生关系建设,加强师生关系问题的源头治理,抓住关键环节培育适应时代发展要求的新型高等学校师生关系,已经成为我国高等教育实现高质量发展的迫切需要.
