STUDIES ON THE CLASTOGENIC POTENTIALITIES OF VIOLA ODORATA IN ALLIUM ROOT MERISTEM

Decoction of Viola odorata,an Indian medicinalplant (varnacular ’Banafshah’),is used asan expectorant.Studies were intended to knowthe effect of this decoction on dividing cellsas well as its potentialities in counteractingcytotoxicity of known chemicals,The

生物复合材料用亚麻/PLA预形纱的制备与优化

由可再生资源生产的生物复合材料是合成纤维增强塑料复合材料的潜在替代品,其中的可再生资源由天然纤维增强生物聚合物组成。对用于生物复合材料的亚麻/PLA预形纱的研发进行了论述。采用Box-Behnken试验设计和响应面分析法研究了纺纱工艺参数对纱线拉伸强度的影响。根据转杯纺工艺参数所得的表达式可用于预测纱线的拉伸强度,且预测结果与试验结果基本保持一致。
