1Intelligent geospatial maritime risk analytics using the Discrete Global Grid System显示文摘Each year,accidents involving ships result in significant loss of life,environmental pollution and economic losses.The promotion of navigation safety through risk reduction requires methods to assess the spatial distribution of the relative likelihood of occurrence.Yet,such methods necessitate the integration of large volumes of heterogenous datasets which are not well suited to traditional data structures.This paper proposes the use of the Discrete Global Grid System(DGGS)as an efficient and advantageous structure to integrate vessel traffic,metocean,bathymetric,infrastructure and other relevant maritime datasets to predict the occurrence of ship groundings.Massive and heterogenous datasets are well suited for machine learning algorithms and this paper develops a spatial maritime risk model based on a DGGS utilising such an approach.A Random Forest algorithm is developed to predict the frequency and spatial distribution of groundings while achieving an R2 of 0.55 and a mean squared error of 0.002.The resulting risk maps are useful for decision-makers in planning the allocation of mitigation measures,targeted to regions with the highest risk.Further work is identified to expand the applications and insights which could be achieved through establishing a DGGS as a global maritime spatial data structure.Andrew Rawson Zoheir Sabeur Mario Brito 2022Big Earth Data2022,6,3:3

3Integrating species and successional classes for wood production in a mixed forest restoration system in a neotropical region显示文摘As forests in neotropical regions,particularly in developing countries,are devastated,interventions to restore biodiversity and its ecological functions are needed.Rural producers have thus been encouraged to grow trees for wood production as an economic activity.The objective of this study was to quantify the increment of wood density of four forest species from different successional classes of a mixed system of restoration in a neotropical forest in Brazil.Tree discs were sampled at breast height and analyzed radially by X-ray densitometry to obtain apparent density and basic density.Three trees each of a species from the pioneer,early and late secondary successional stages and of the dominant species in the climax community.The radial profiles indicated increasing density from the pith to bark of trunks,except for some variations due to wood defects and growth.Average density was 0.576 g cm^(-3),0.655 g cm^(-3),0.706 g cm^(-3)and 0.775 g cm^(-3),respectively,for Peltophorum dubium,Schinus terebinthifolius,Cariniana estrellensis and Hymenaea courbaril.Radial profiles indicated higher amplitudes in the apparent densities for slow-growing species.X-ray densitometry generated parameters such as minimum,average and maximum densities,and radial density variations.These parameters are important for understanding the ecological functional role of successional classes of the Atlantic Forest from the Neotropical region.Ananias Francisco Dias Junior Ana Lucia Martins Sodero Pincelli Ana Paula Camara da Silva Alison Moreira da Silva Natalia Dias de Souza Mario Tommasiello Filho Jose Otavio Brito 2021Journal of Forestry Research2021,32,6:1
4A multi-integrated approach on toxicity effects of engineered TiO2 nanoparticles显示文摘设计 nanoparticles 的新性质在有机体和生态系统上在安全,命运,行为和这些粒子的生物学的效果上为新知识驾驶需要。钛二氧化物 nanoparticles 为大量应用广泛地被使用了,例如,自我清洗的表面涂层,太阳能电池,水处理代理人,热门 sunscreens。在这种情形以内,增加的环境暴露能被期望,但是 nanoparticles 的 ecotoxicological 评估上的数据仍然是少见的。这个工作的主要目的是在几个有机体的 TiO 2 nanoparticles 的效果的评估,盖住不同营养的层次,用一组水的试金。也用组织学的脊椎动物模型有机体纸巾和 ultrastructural 观察和压力酶活动是的鱼学习了。TiO 2 nanoparticles (Aeroxide?P25 ) ,锐钛矿(65%) 的二篇阶段作文和有一个平均粒子的金红石(35%) 缩放 27.6Ana PICADO Susana M.
