做情绪的主人——谈教师情感发展训练

情绪就象空气,无论我们做什么,学什么,想什么,都伴随着情绪。情绪高昂时,会使人精神焕发,欢快愉悦,感觉生活充满阳光。情绪低落时,又会让人垂头丧气,提不起精神,感觉生活缺乏希望。对于情绪的掌控,关键在于如何进行调节和利用。作为经常要面对学生、家长的教师,如何才能对情感加以优化,更好地控制情绪呢？     

从建安风骨到盛唐气象的重要拐点——论陈子昂对建安文学的传播接受

陈子昂从理论、创作与为人三个方面肯定和接受建安文学，发掘了建安文学别于且高于六朝文学的价值，将建安文学提升到革除文弊与重振文风的重要地位，他通过自己的努力与影响力，使建安文学得到广泛认可与传播，成为影响盛唐文学发展的主流力量。陈子昂之后，建安文学被奉为正宗，对盛唐气象之形成功莫大焉。     

Stem cells in microfluidics

Microfluidic techniques have been recently developed for cell-based assays. In microfluidic systems, the objective is for these microenvironments to mimic in vivo surroundings. With advantageous characteristics such as optical transparency and the capability for automating protocols, different types of cells can be cultured, screened, and monitored in real time to systematically investigate their morphology and functions under well-controlled microenvironments in response to various stimuli. Recently, the study of stem cells using microfluidic platforms has attracted considerable interest. Even though stem cells have been studied extensively using bench-top systems, an understanding of their behavior in in vivo-like microenvironments which stimulate cell proliferation and differentiation is still lacking. In this paper, recent cell studies using microfluidic systems are first introduced. The various miniature systems for cell culture, sorting and isolation, and stimulation are then systematically reviewed. The main focus of this review is on papers published in recent years studying stem cells by using microfluidic technology. This review aims to provide experts in microfluidics an overview of various microfluidic systems for stem cell research.
