1. Rock Evaluation Using Digital Images and Drill Monitoring Data : Before and after rock blasting
Sammanfattning : This research is carried out to better understand the nature of the rock mass and to have a better anticipation of rock fragmentation before blasting the rock mass. Current practices of assessing rock mass usually involve techniques that focus on the surface or outcrop of the rock mass such as scanline surveys, window surveys, photogrammetry and laser scanning etc. LÄS MER
2. Role of Fragmentation at the Production Level of a Sublevel Caving Operation
Sammanfattning : This research was conducted to evaluate the association of rock fragmentation with different unit operations of a sublevel caving (SLC) production cycle. Drilling, charging, and blasting, as well as the nature of the rock mass, can affect the fragmentation observed at the drawpoints. LÄS MER
3. Preparation and long-term performance of poly(ethylene-co-butyl acrylate) nanocomposites and polyethylene
Sammanfattning : The current study discusses the preparation and long-term performance of polymer composites used for various purposes under different ageing conditions.The first part deals with the preparation and characterization of polymer nanocomposites based on poly(ethylene-co-butyl acrylate) (EBA–13 and EBA–28 with 13 and 28 wt % butyl acrylate, respectively) and 2–12 wt % (0.

4. Experimental and Theoretical Studies of Metal Adsorbates Interacting with Elemental Semiconductor Surfaces
Sammanfattning : Metal adsorbates on semiconductor surfaces have been widely studied over the last few decades. The main interest is focused on various one or two-dimensional structures that exhibit interesting electronic and atomic properties. This thesis focuses on metal adsorbates interacting with the Si(111) and Ge(111) surfaces. LÄS MER
5. Atomic and electronic structures of two-dimensional layers on noble metals
Sammanfattning : Two-dimensional (2D) materials, in the form of a single atomic layer with a crystalline structure, are of interest for electronic applications. Such materials can be formed by a single element, e.g., by group IV or group V elements, or as a 2D surface alloy. LÄS MER
