In this study, the austenitic, corrosion-resistant N50 steel alloyed with different nitrogen, niobium and vanadium content was investigated. This steel is used in the production of high-strength, cryogenic pipes. The production process for these pipes involves aging at 650 °C–665 °C for 50–100 h. Therefore, steels were examined in their as-delivere...

Local waterlogging often occurs on the steep slopes of clayey–calcareous soils in southwestern France, causing nutrients and pollutants transfer to the river bodies and reduced ecosystems services. These soils developed in the Miocene molassic hill formation and are generally impermeable with abundant traces of hydromorphy and heterogenous spatial ...

The influence of reheating temperatures on hot ductility is investigated in two Ni-, Mo-, and Cu-containing low-carbon steels. The effects of solution treatment conditions at 1623, 1673 K, and remelting at 1803 K on the reduction in area (RA) are analyzed. The results show an RA trough in the range of 973–1173 K in all experimental conditions. At 9...

Understanding the impact of climate change on vegetation is essential to manage a new adaptation strategy and preserve the ecology impacted by the flow of suspended matter towards the watercourse. The main purposeof the present article is to study the relationship between the normalized difference vegetation index (NDVI) and the precipitation (P), ...

In some contexts, the only solution to manage the risk of slope instability induced by precipitation is to set up an early warning system. Such systems are designed to issue warnings at the right time to enable action to be taken and to guarantee public safety, for landslides can be deployed at the scale of a single slope or at regional scale. Some...

Raziskovali smo vpliv mikrolegirnih elementov niobija, titana, itrija in cirkonija na rast kristalnih zrn v avstenitnem nerjavnem jeklu AISI 304 pri temperaturah žarjenja od 1050 °C do 1200 °C ter časih žarjenja od 0 do 8 ur. Velikost kristalnih zrn je bila ocenjena pod svetlobnim mikroskopom s primerjalno metodo po standardu ASTM E112, izmerili sm...

In this study, the microstructure, precipitations, and microsegregation in the laser additive manufactured thin-wall structure of a single-crystal superalloy are synthetically characterized. The influence of a subsequent heat treatment on the microstructure and precipitations is discussed. The results show that under the given processing conditions...

In many domains, such as weather forecasting, hydrology or civil protection, it is an important issue to characterize rainfall variability and intermittency in, either or both, a given time period or area. A variety of sensors, for instance, rain gauges, weather radars, and satellites are widely used for this purpose. Techniques to establish the si...

Les lacs et retenues d’eau d’Afrique sont primordiaux à la vie dans les régions qu’ils bordent. Le niveau de ces lacs est fortement dépendant des précipitations qui tombent directement à leur surface et dans leur bassin versant. Dans un but de gestion de la ressource en eau, il est important d’analyser et de prévoir l’évolution passée, en temps rée...
