Additive Manufacturing In Situ and Ex Situ Geometric Data Registration
Journal of Computing and Information Science in Engineering, 2022Abstract Recently, the number and types of measurement devices that collect data that are used to monitor laser-based powder bed fusion of metals processes and inspect additive manufacturing metal parts have increased rapidly. Each measurement device generates data in a unique coordinate system and in a unique format.

A review on ex situ mineral carbonation
Environmental Science and Pollution Research, 2021The increased CO2 quantities in the environment have led to many harmful effects. Therefore, it is very important to decrease the CO2 levels in the environment. CO2 capture along with safe and permanent storage using mineral CO2 sequestration method can play an important role to reduce carbon emissions into the environment.

This chapter looks into ex situ conservation. It acknowledges that in situ conservation techniques might be needed if a successful ex situ conservation programme, which is termed reintroduction, is achieved. The chapter explores the subdivisions of ex situ conservation: intensive or general captive breeding programmes and gene banks.

This chapter focuses on ex situ (off-site) conservation, which is the protection and management of biodiversity in artificial, human-built environments. Indeed, ex situ conservation allows wild-caught individuals to be maintained under close human supervision in facilities like zoos, aquariums, botanical gardens, or arboretums.

Ex Situ Aqueous Mineral Carbonation
Environmental Science & Technology, 2007The U.S. Department of Energy's National Energy Technology Laboratory (NETL) located in Albany, OR (formerly the Albany Research Center) has studied ex situ mineral carbonation as a potential option for carbon dioxide sequestration. Studies focused on the reaction of Ca-, Fe-, and Mg-silicate minerals with gaseous CO2 to form geologically stable ...

Velocity imaging by ex situ NMR
Journal of Magnetic Resonance, 2005A pulsed field gradient stimulated spin-echo NMR sequence is combined with imaging methods to spatially resolve velocity distributions and to measure 2D velocity maps ex situ. The implementation of these techniques in open sensors provides a powerful non-invasive tool to measure molecular displacement in a large number of applications inaccessible to ...

In Situ and Ex Situ Conservation of Chinese Plants
2020In total, 28,385 higher plants were distributed in the nature reserves, accounting for 77.0% of the total number of higher plants in China. Among them, there are 3842 species which are effectively protected; 2478 species are better protected. More than 84.4% endangered species grow in national and/or provincial natural reserves.

In situ and ex situ Cu doping of MgB2
Physica C: Superconductivity, 2005Abstract The effect of in situ and ex situ Cu doping on MgB 2 was studied in the annealing temperature range of 600 °C–900 °C. Attempts to substitute Cu into MgB 2 resulted in the formation of Mg–Cu phases. Within the limits of error, neither lattice strain nor significant alteration in a - and c -axes was introduced by varying annealing ...
