Palm oil shell aggregate as cool pavement by replacing fine aggregate
… to be less heat absorbent. Palm Oil Shell Aggregate (POSA) is the material that is identified as having a potential to be the cool pavement due to the presence of Near Infrared Region (NIR) reflective component and void after POSA is replaced in asphalt pavement. Therefore, the study is …

Aggregate and disaggregated fluctuations
… a concave frontier induces short-run aggregate effects of relative demand shifts, thereby fostering the propagation of the shocks under consideration, which overall account for 86% of the aggregate fluctuations. When I identify shocks with curvature, the N-shock appears to be …

Shipboard aggregate power monitoring
… load activity with power measured from an aggregate level in the distribution system. Additionally, a critical evaluation is conducted on the current NILM configuration's ability to perform automated classification. Findings will be supported using data collected from NILMs monitoring power …

Assessment of alkali aggregate reaction avoidance measures and alkali aggregate reaction tests worldwide
Alkali Aggregate Reaction (AAR) is a deterioration mechanism which affects concrete structures all over the world. Different parts of the world employ various mitigation and control measures for AAR damage. Different tests are also performed worldwide to assess AAR. With the variety of AAR …

Investigating Use of Aggregate Density to Develop Design Aggregate Structure for Asphalt Concrete Mixtures
… are various potential causes for the failures, aggregate density within the mix when designed at 80 gyrations was of specific concern to this thesis and was compared to the maximum dry density of the aggregate as measured using ASTM D4253-00. The objective of this research was to determine if …

Characterization of Emulsion Aggregate Mixtures
The engineering properties of Emulsion-Aggregate Mixtures (EAM's) are characterized using laboratory and field testing. Dense-graded and open-graded aggregates treated with HFE-300 and CSS-1 emulsions are evaluated. Shear strength, repeated loading response (resilient modulus, permanent …

Seismic characterization of recycled aggregate concrete
… of recycling waste concrete and reusing it as aggregate for structural concrete, but the use of Recycled Aggregate Concrete (RAC) is yet limited to non-structural applications such as road sub-base. Widespread application of RAC in areas such as seismic design requires an improved knowledge of …

Quantification of Aggregate Formation in Prochlorococcus
… regarding its lifestyle. Over recent years, aggregates have been regularly observed forming at the bottom of Prochlorococcus cultures, somewhat resembling macroscopic biofilms formed by related bacteria. This study aimed to investigate and quantify this aggregate formation in Prochlorococcus. …

Recycling waste concrete into road pavement aggregate
The use of recycled concrete aggregate (RCA) as a road pavement material in Australia is relatively recent and confined mainly to Victoria and New South Wales. Samples of RCA were taken at six, monthly intervals from a local producer of RCA. A range of tests was carried out to provide initial …

Evaluation of the compacted aggregate resistance test
The Compacted Aggregate Resistance (CAR) test is a procedure used to analyze the quality of asphalt. It is a punch shear test that indirectly measures the shape and angularity of fine aggregates. The CAR test is in the developing process of replacing the current Superpave standard for fine …

Characterication of aggregate gland silk factor 1
… In these studies, we characterize the aggregate gland specific factor 1 (AgSF1) from the black widow spider, Latrodectus hesperus. After the development of an anti-AgSF1 polyclonal antiserum, we demonstrate by western blot analyses that the AgSF1 protein is highly expressed in the …

Essays on Aggregate Liquidity and Corporate Events
… Motivated by existing studies in firm-level and aggregate-level liquidity, which suggest the influence of (aggregate) liquidity on the activity and quality of corporate events, the purpose of this thesis is to investigate and understand the role of aggregate liquidity in explaining existing …

Charging of aggregate grains in astrophysical environments.
… indicate that cosmic dust is likely to have an aggregate structure. This study examines the charging of aggregate grains in different astrophysical environments. A 3D numerical model employing a self-consistent iterative approach to compute the aggregate charge is introduced. Different size …
