Design and Implementation of the Earthquake Disaster Loss Assessment System Based on GIS [PDF]
, 2013 新疆地震活动分布广、强度大、频度高、类型全，是我国地震灾害最为严重的地区之一。随着西部大开发战略的实施，我区社会、经济将有更快的发展，城市生命线工程、重大工程、特殊工程及基础设施建设规模将不断扩大，城镇化进程将加快，在这样一个多震的地方，一旦发生破坏性地震，其损失将会加大。因此，在积极发展经济的同时，努力减轻地震灾害带来的人员伤亡和财产损失，把地震对社会的影响控制到最小程度，是地震应急管理工作的重要任务。 在当今科研条件下，人类尚无法控制地震的发生也不能在震前对地震进行准确的预报 ...

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Tungsten is inherently brittle and particularly prone to thermal stress concentration and crack formation during additive manufacturing processes such as laser cladding, which severely limits its engineering applications as a coating material. To address this issue, this study proposes an in situ toughening strategy involving the introduction ...

Risk, Hazards &Crisis in Public Policy, Volume 16, Issue 1, March 2025.ABSTRACT Disaster insurance is gaining prominence as a tool to address climate‐induced loss and damage in developing countries. Despite ongoing efforts to pilot disaster insurance in Malawi, adoption by households remains low. This study examines factors influencing the adoption of disaster insurance in Malawi, a country highly susceptible to climate ...

A practical approach to meeting national obligations for sustainable trade under CITES
Conservation Biology, Volume 38, Issue 5, October 2024.Abstract Reconciling conservation goals with sustainable resource use requires adaptive management strategies. The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) regulates global trade for species listed on Appendix II, partly by requiring member countries (parties) to ensure exports do not damage wild ...
