| 1 | Experimental evaluation and simulation of volumetric shrinkage and warpage on polymeric composite reinforced with short natural fibers显示文摘聚合天赋增强纤维合成被挤出和注射塑造过程开发。与 Guadua angustifolia Kunth 的短自然纤维增强的高密度的聚乙烯的收缩和 warpage 被试验性的大小和计算机模拟分析。Autodesk Moldflow?并且固体工作?被采用在不同配置模仿注射部分的容量的收缩和 warpage:在收缩和聚合物的 warpage 行为上增强的 0 wt.% , 20 wt.% , 30 wt.% 和 40 wt.% 合成。变得明显在注射部分的容量的收缩和 warpage 上增强的限制效果。结果显示天赋的那容量的收缩合成与纤维增加被减少直到 58% ,而 warpage 显示出减小,与主要纤维内容形成 79% ~ 86% 。这些结果建议改进聚合自然增强纤维的 composites 的集会性质是自然纤维的高度有益的使用。 | Jonnathan D.

| 7 | Has global deforestation accelerated due to the COVID-19 pandemic?显示文摘As the COVID-19 pandemic unfolded,questions arose as to whether the pandemic would amplify or pacify tropical deforestation.Early reports warned of increased deforestation rates;however,these studies were limited to a few months in 2020 or to selected regions.To better understand how the pandemic infl uenced tropical deforestation globally,this study used historical deforestation data(2004–2019)from the Terra-i pantropical land cover change monitoring system to project expected deforestation trends for 2020,which were used to determine whether observed deforestation deviated from expected trajectories after the fi rst COVID-19 cases were reported.Time series analyses were conducted at the regional level for the Americas,Africa and Asia and at the country level for Brazil,Colombia,Peru,the Democratic Republic of Congo and Indonesia.Our results suggest that the pandemic did not alter the course of deforestation trends in some countries(e.g.,Brazil,Indonesia),while it did in others(e.g.,Peru).We posit the importance of monitoring the long-term eff ects of the pandemic on deforestation trends as countries prioritize economic recovery in the aftermath of the pandemic. | Jonnathan Céspedes Janelle M.Sylvester Lisset Pérez-Marulanda Paula Paz-Garcia Louis Reymondin Mehran Khodadadi Jhon J.Tello Augusto Castro-Nunez | 2023 | Journal of Forestry Research2023，34，4： | 0 |
