This chapter highlights important new trends in Mesolithic archaeology by presenting some myths. Put crudely, myths help us to tell stories, or guide other actions. Whilst myths may have their origins in a real event or process, such stories also grow in the telling, and take on a life of their own. And myths, of course, reveal much about the community within which they exist. The chapter explores three myths of the Mesolithic, the first of which explores ‘Mesolithic monuments’. The second relates to analytical scale. Finally, the myth in early Mesolithic Britain is explored.

Air Humidification

The drying phenomenon can be treated as simultaneous heat and mass transfer in both the light and heavy phases. In the present case, the phenomenon’s evolution is normally observed through the heating of and moisture removal from the heavy phase. On the other hand, while the material is heating, the light phase is cooling and humidifying. The goal of the present work is to present discharge air humidification curves as a function of the drying time for Eucalyptus staigeriana leaves drying experiments. For the air humidification measurements, a dry bulb thermocouple and relative humidity transducer were installed at both the dryer inlet and outlet. The dryer was linked to a data acquisition system, which recorded the dry bulb temperature and the relative humidity with time. These data were later used to calculate the air moisture content at the dryer inlet and outlet. The data obtained by this methodology are compared with the ones from drying kinetic (moisture content removing of the heavy phase along time), acquired by the evolution of wet material weight through the use of an analytical scale.

The dichloromethane (DCM) extract of the fruits of Peucedanum schottii Besser ex DC. (Apiaceae) was subjected to high-performance counter-current chromatography (HPCCC) for the efficient and fast separation (30 min) and isolation of cimifugin using an ethyl acetate: water (1:1 v/v, K = 1.01) system. The analytical scale-optimized separation was easily scaled to semi-preparative conditions. Cimifugin (11.25% yield, 96.5% purity) was isolated for the first time from P. schottii and characterized by NMR spectroscopy. Cimifugin and the crude DCM extract were evaluated using ELISA microtiter assays for their inhibitory potential against the cholinesterases (acetylcholinesterase - AChE and butyrylcholinesterase - BChE), and tyrosinase (TYR), which are key enzymes for the treatment of some neurodegenerative diseases, i.e. Alzheimer's and Parkinson's. The crude extract exhibited a weak inhibitory activity against AChE, BChE, and TYR (4.2, 35.5, and 0% at 100 μg mL−1 and 10.3, 40.0, and 12.2% at 200 μg mL−1, respectively), while cimifugin displayed low to moderate inhibition towards AChE and BChE (3.1 and 21.6%, respectively) at 200 μg mL−1.
