Three cooking methods, namely boiling, steaming, and stir-frying for 5 to 10 min, were used to evaluate the effect on nutrient
components, free amino acids, l-ascorbic acid, total phenolic contents, and antioxidant capacities of bamboo shoots (Phyllostachys praecox). Results showed that boiling and stir-frying had a great effect on the nutrient components and they decreased the contents
of protein, soluble sugar, and ash, and caused a great loss in the total free amino acids (decreased by 38.35% and 34.86%,
respectively). Significant differences (P<0.05) in free amino acids were observed in the samples cooked by different methods. Stir-fried bamboo shoots had a high fat
content which increased by 528.57% because of the addition of edible oil. After boiling, the L-ascorbic acid and total phenolic
contents were significantly reduced, while steaming increased total phenolic content by 3.98% and stir-frying well-preserved
L-ascorbic acid (78.87% of its previous content). Results of the antioxidative property study showed that stir-frying could
increase antioxidant capacities of bamboo shoots. It is concluded that stir-frying is more suitable for bamboo shoots because
it could obtain the maximum retention of antioxidant capacities. 相似文献

本文以法学视角,尤其是国际法视角,通过研读规则文本的方式,对足球规则的演进进行分析,并且揭示一些目前体育法领域关注的问题:体育法(lex sportiva)确实存在,包含了公法部分(国际公约、国家立法)和私法部分(体育规则);体育规则(Laws of the game)是体育法的核心,包括国家、地区以及全球范围内各级体育主管部门的章程与条例;项目规则是体育法的另一个重要核心,作者以足球为例,论证了为什么项目规则也是法的问题。 相似文献

OBJECTIVE: The goals of this current project were to expand and elaborate on the results of Varia, Abidin, and Dass' (1996) study to better understand what historical parenting factors may contribute in creating a "Minimizing" perception of childhood psychological abuse. A second objective included examining the association between perceptual styles and adult ratings of adult relationship satisfaction. METHOD: Ninety individuals from a non-clinical adult sample completed self-report questionnaires regarding psychological maltreatment and adult relationship satisfaction. Three groups were created and compared using analysis of variance. The groups were (I) "Non-Abused," consistent reporters of no abuse; (II) "Acknowledgers," consistent reporters of abuse; and (III) "Minimizers," reporters of abuse, but do not label themselves as having been abused. RESULTS: Results indicated a continuum effect with the Non-Abused individuals reporting the highest level of maternal warmth and affection, the Acknowledgers reporting the lowest, with the Minimizers in the middle. The Non-Abused group reported the healthiest adjustment in terms of adult relationship satisfaction. While Minimizers and Acknowledgers reported similar levels of psychologically abusive experiences, Acknowledgers reported more difficulties with adult relationships. CONCLUSIONS: This study highlights the importance of studying Minimizers, a group which describes abusive events but minimizes the meaning and scope of these experiences. The relatively higher levels of maternal care which the Minimizers reported is hypothesized to be associated with their perceptions that they were not abused and acted as a protective factor associated with better quality adult relationships. The varying degrees of nurturance and care in the early family environment of abused individuals is speculated to be associated with distinct perceptual styles. 相似文献

在速度滑冰中,成绩与运动员每次蹬冰所产生的功量和蹬冰的频率乘积有关。运动员每次蹬冰所做的功取决于与滑行方向垂直的蹬冰力的分力。通过对三个受过训练的速滑运动员测试,测定他们在不同速度时的蹬冰力。结果表明;在不同的速度时,最大的蹬冰力与平均蹬冰力并不改变。而且速度越大,蹬冰时间越短。由此可见,速滑运动员并不是通过改变蹬冰力的大小,而是通过改变蹬冰时间来调节速度。蹬冰力——时间曲线的图形形状取决于蹬冰技术,并且直道滑行与弯道滑行的曲线形状也有区别。速度滑冰的成绩与运动员用于克服空气和冰面摩擦阻力的外功P。密切相关(Ingen Schenau)。外功P。等于每次蹬冰 相似文献
