  1. 1. Archaeological Perspectives on Risk and Community Resilience in the Baringo Lowlands, Kenya

    Författare :Nik Petek; Paul Lane; Matthew Davies; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Risk spiral; community resilience; archaeology; pastoralism; Baringo; Kenya; history; Ilchamus; Njemps; spatial statistics; East Africa; Holocene; environment; environmental degradation; colonialism; ethnogenesis; community conformity; survey; remote sensing; habitation; subsistence; Archaeology; Arkeologi;

    Sammanfattning : This historical ecological research provides a detailed insight into the risk avoidance and resilience building strategies in the Lake Baringo basin in Kenya through the lens of archaeology. It explores how changes in subsistence, habitation, and landscape shaped each other and how that affected the available strategies of risk avoidance and resilience building. LÄS MER

  2. 2. Vibrational Sum Frequency Spectroscopy Studies at the Air-Liquid Interface

    Författare :Eric Tyrode; Mark Rutland; Paul Davies; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sum Frequency Generation; SFG; VSFS; surfactant; adsorption; water; surface structure; hydration; surface tension; fluorosurfactants; liquid-air interface; poly ethylene oxide surfactants; surface molecular orientation; acetic acid.; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : In this thesis the structure and hydration of small organic and amphipilic compounds adsorbed at the air-liquid interface, have been studied using the nonlinear optical technique Vibrational Sum Frequency Spectroscopy (VSFS). The second order nature of the sum frequency process makes this technique particularly surface sensitive and very suitable for interfacial studies, as molecules at the surface can be distinguished even in the presence of a vast excess of the same molecules in the bulk.
