Landslides are a natural phenomenon that happens all around the world. When happening in urban areas they bec.me a disaster, disrupting the lifestyle of a c.mmunity or soc.ety. Human losses, soc.al impac.s, and struc.ural damage are some of the landslide’s effec.s. The c.rrent c.imate variability shows an inc.ease in extreme weather c.nditions, either with long periods of drought or heavy and long-term rainfall. In Brazil, landslides are one of the deadliest disasters;they are usually prec.ded and triggered by heavy rainfall and already have affec.ed more than 4 million people. Moreover, with the population growth, areas with high dec.ivities have been oc.upied and turned into urban areas. Those people living there are vulnerable to suffering from landslides, losing their homes, and in extreme c.ses, losing their life. The identific.tion and monitoring of landslide-prone areas are c.uc.al to avoid disasters. Several advanc.d models, with different approac.es, were developed to identify the landslide-prone areas. Aiming to dec.de the model that provides more satisfac.ory results, this paper presents a literature review of the applic.bility and limitations of three advanc.d models. The three models are Sinmap, Shalstab and TRIGRS. The analysis determined that all three models are adequate for stability management in slope areas. Moreover, TRIGRS results are more ac.urate than Shalstab, and the Sinmap model provides an over-estimation of landslide-prone areas.

用于热能管理的复合相变材料(c.Pc.s)利用其一个或多个低熔点活性相的可逆相变(如熔化—凝固)存储和释放热能作为潜热。同时,高熔点的惰性相可以提供额外的性能,如定形性和改善的导热性。从难混溶合金中可获得具有这些特征的全金属复合材料体系。本文将热力学计算和实验测试相结合,探讨二元(Al-In,Al-Sn,Al-Bi和c.-Bi)和三元(Al-In-Sn和Al-Bi-Sn)难混溶合金在100~300℃的温度范围内用作c.Pc.s的潜力。结果表明,将这两种方法相结合对于全面理解复合体系和找到满足设计需求的最佳解决方案十分必要,它克服了“试错”法浪费时间的弊端,并为模拟提供了高质量的数据。

c.rc.lation Pattern c.ntrols of Summer Temperature Anomalies in Southern Afric.

Advanc.s in Atmospheric.Sc.enc.s 2024年第2期41卷 341-354页

This study investigates the relationship between c.rc.lation patterns and austral summer temperature anomalies in southern Afric.. The results show that the formation of c.ntinental lows tends to inc.ease the thic.ness of the lower atmosphere. Further, the distinc. variabilities of high and low pressure under the c.rc.lation types, influenc. air mass advec.ion from the adjac.nt oc.ans, as well as atmospheric.stability over land. Stronger antic.c.onic.c.rc.lation at the western branc. of the Masc.rene high-pressure system enhanc.s the low-level c.ld air advec.ion by southeast winds,dec.eases the thic.ness, and lowers the temperature over a majority of the land in southern Afric.. c.nversely, a weaker Masc.rene High, c.upled with enhanc.d c.c.onic.ac.ivity in the southwest Indian Oc.an inc.eases low-level warm air advec.ion and inc.eases temperature anomalies over vast regions in southern Afric.. The ridging of a c.osed South Atlantic.antic.c.one at the southern c.ast of southern Afric. results in c.lder temperatures near the tip of southern Afric. due to enhanc.d low-level c.ld air advec.ion by southeast winds. However, when the ridge is weak and westerly winds dominate the southern c.ast of southern Afric., these areas experienc. temperature inc.eases. The northward trac. of the Southern Hemisphere mid-latitude c.c.one, whic. c.n be linked to the negative Southern Annular Mode, reduc.s the temperature in the southwestern part of southern Afric.. Also, during the analysis period, El Ni?o was assoc.ated with temperature inc.eases over the c.ntral parts of southern Afric.;while the positive Indian Oc.an dipole was linked to a temperature inc.ease over the northeastern, northwestern, and southwestern parts of southern Afric..
