为提高无机填料在牙科复合树脂中的堆积密度,采用八乙烯基多面体低聚倍半硅氧烷(OV-POSS)作为第三级填料,填充双模SiO2填料(SiO2纳米粒子&SiO2纳米团簇)型复合树脂中的空隙。用高分辨率透射电镜(HR-TEM)和动态光散射仪(DLS),研究了OV-POSS的形貌和粒径,并利用UV-vis-NIR分光光度计、万能实验机和MTT比色法,研究了三级填料的组成对复合树脂性能的影响。结果表明:OV-POSS形貌为近球形,粒径为(4.0±2.9)nm;当OV-POSS的添加量≤5wt.%时,复合树脂的性能逐渐得到改善,尤其当OV-POSS的质量分数为5%时,复合树脂的透光率和细胞活性优于商品化纳米团簇型树脂z350 XT,且其弯曲强度(112.3 MPa±5.6 MPa)、弯曲模量(6.6 GPa±0.2 GPa)和压缩强度(217.8 MPa±5.3 MPa)达到最大值,较未添加OV-POSS的树脂分别提高了7.2%、4.8%和5.8%。但是,随着OV-POSS含量增加(≥10wt.%),OV-POSS易聚集且散射更多的光,导致复合树脂性能下降。

The study evaluated the effects of rations incorporating maggot concentrate (CA) as a substitute for fishmeal on growth performance and post-weaning piglet’s production costs. To do this, twenty-four (24) weanlings of large white breed were divided into 3 batches of 8 pigs each for a comparative rationing test in 2 phases. Four (04) experimental rations containing CA, two experimental rations (RI10 and RI5-5) for the 1st phase and two others (RII5 and RII10) for the 2nd phase were tested in comparison with 2 control rations RTI10 and RTII5 for the respective Phases I and II. The results show that in all phases piglet growth was continuous from the beginning to the end of each phase. In Phase I, the ADGs of piglets fed RI5-5 (138.64 g), RI10 (131.28 g) and RTI10 (104.78 g) were homogeneous (p > 0.05). The food production costs of one kg of live weight (FCkgLW) of the RI5-5 (671.39 CFAF) and RI10 (690.57 CFAF) rations were significantly lower than the RTI10 (1083.68 CFAF) ration (p ous (p > 0.05). The FCkgLWs of RII10 (506.73 FCFA), RII5 (583.43 FCFA) and RTII5 (815.53 FCFA) were homogeneous (p > 0.05). The maggot concentrate can be used as a source of animal protein in the feeding of piglets in partial or total substitution for fish. The evaluation of the effects of its use on the quality of carcasses and meat will be necessary.
