脂肪含量与煮制条件对鹅肝酱物理特性的影响

鹅肝酱是一种源于法国的著名美食,由于饲养与鹅种的差异,我国普通鹅肝与法国鹅肥肝在营养成分上存在差别,导致鹅肝酱的口感和风味降低。实验利用皖西白鹅鹅肝为主要原料,通过质构仪检测不同脂肪添加量和煮制条件下的鹅肝酱的硬度、咀嚼性、弹性、粘着性。最终结合两者的结果,得出利用本土鹅种的普通鹅肝加工生产鹅肝酱时,按质量比2∶1添加猪肥膘肉,同时以85℃煮制3.5h可得到鹅肝酱最佳物理特性。该研究对促进我国本土鹅产业发展有一定的参考价值。     

影响啤酒感官评定的因素探讨

啤酒是世界上产量最大、酒精含量最低、营养较为丰富的酒种.啤酒的质量指标包括感官指标、理化指标、卫生指标.尽管有许多理化评价指标,但远远不能全面评价其外观特征、口感及风味特性.在评价啤酒质量时,感官评价仍然占有很重要的位置.本文探讨了影响啤酒感官评定的诸多因素,减少了主观因素与客观因素对评定员的影响,提高感官评定的准确性.

快速诊断小鹅瘟PCR方法的优化建立

为建立快速诊断小鹅瘟的PCR方法,根据已发表的GPV主要结构蛋白VP3基因序列,经多序列比对和Oligo6．0软件分析设计特异性PCR引物。以微量法提取病鹅肝组织DNA,优化PCR反应引物退火温度、循环次数和鉴定其特异性,并与酚氯仿法和煮沸法进行同步对比研究。结果显示,建立的PCR检测方法能够特异性检测病鹅肝组织中GPV的核酸,其扩增片段大小为343bp,最佳退火温度为58℃,最佳循环次数为35次。微量法提取的病毒核酸PCR检测灵敏度分别是酚氯仿法的50倍和煮沸法的2500倍。该PCR检测方法不与鹅副黏病毒、禽流感病毒、传染性支气管炎病毒、鸭瘟病毒以及健康鹅肝组织发生交叉反应。本研究建立的GPVPCR检测方法能够快速诊断小鹅瘟。

融合多元感官，感受音乐之美——浅议“多感官体验”在小学音乐课堂中的运用

在所有的艺术门类中,音乐是最为抽象的,其具有非语义、非视觉性的特点,以音响为载体来传达情感。音乐课堂上学生的音乐体验主要以听觉为主,动觉切入,视觉为辅,在多元感官融合中感受音乐。本文旨在对"多感官体验"做出解释,阐述"多感官体验"在世界三大教学法中的体现,以及论述其在小学音乐课堂中的运用。

What is the current level of knowledge and confidence of mainstream school SENCOs in sensory integration theory and using sensory strategies within education?

The aims of the study were: to identify the number of SENCOs who have received specific training on sensory integration. To determine the understanding of the eight senses and sensory integration theory and sensory strategies. Determine any common gaps in knowledge or misconceptions. Fifty-five surveys were completed. 40% of respondents had received training on sensory processing. There was a significant chi-squared correlation between those that had received training and those that stated they did not know or made guesses about what the vestibular and proprioceptive senses are important for. There was a correlation between those that had received training and those that had good knowledge of the signs of sensory hyper-responsivity. There was no statistical significance of increased knowledge on sensory hypo-responsivity between those who had and had not received training. SENCOs who rated their school as being sensory-friendly had a greater understanding of what sensory integration is important for. Pertinently, those who rated their school as being ‘sensory-friendly’ (45.5%) were 8.5 times more likely to know sensory integration is needed for self-regulation. A number of recommendations are made including the need for greater collaboration between therapists and teachers to increase understanding of sensory integration and the impact of this on a child's education and wellbeing at school. Sensory strategy programmes are to be written with teaching staff and not given by the therapist in an ‘expert’ role. Sensory integration awareness training, including why and how to utilise sensory strategies, is to be encompassed in the SENCO national qualification.     

Current conceptions of literacy – insights from work with children and older learners with sensory needs

There have been many efforts to conceptualise literacy, both in terms of its essence and component parts, but it has proved difficult to define. This paper considers work that is undertaken with children and older learners with sensory needs in order to promote the early stages of literacy. Recent government initiatives aimed at fostering literacy development have caused teachers of children with sensory needs to re-examine their practice. The paper discusses early literacy as part of children's attempts to communicate and describes children with sensory needs engaging in a range of activities that are termed 'literacy' by those working with them. By taking into account these activities, the authors endeavour to throw light on the broader questions around concepts of literacy.
