Introduction This pilot study builds on an initial assessment of phytolith preservation in samples from Coppergate and 22 Picadilly (ABC Cinema) which demonstrated adequate to excellent preservation of phytoliths1. At that time, phytolith studies were in their infancy and their true potential for the interpretation of archaeological contexts was unknown. Phytoliths are plant silica microfossils, ranging from 0.01mm to 0.1mm in size and visible only through a high powered microscope. Phytoliths, literally ‘plant rocks’12, are formed from solidified monosilicic acid, which is absorbed by the plant in the groundwater. It is deposited as -

Phytoremediation plants are used for recovery of metal-contaminated soils by their ability to absorb and tolerate high concentrations of heavy metals. This paper aims to evaluate the potential of grasses in phytolith production in soils contaminated with Cd. The experiments, separated by soil types (Typic Quartzipsamment, Xanthic Hapludox and Rhodic Hapludox), were conducted in a completely randomized design with a distribution of treatments in a 3 4 factorial scheme with three replications. The factors × were three grasses (Urochloa decumbens, Urochloa brizantha and Megathyrsus maximus) and four 1 concentrations of Cd applied in soils (0, 2, 4 and 12 mg kg− ). -

During this period, in the context of a steadily ameliorating climate in the aftermath of the Younger Dryas cold spell, small groups of humans across the hilly flanks and high plains of the Zagros chain of mountains of western Iran and eastern Iraq developed their food- procuring strategies to include new modes of intensified plant cultivation (Riehl et al. -
New Investigations in the Environment, History and Archaeology of The
1 NEW INVESTIGATIONS IN THE ENVIRONMENT, HISTORY, AND ARCHAEOLOGY OF THE IRAQI HILLY FLANKS: SHAHRIZOR SURVEY PROJECT 2009–2011 By , , Ü, , , and 1 Recent palaeoenvironmental, historical, and archaeological investigations, primarily consisting of site reconnaissance, in the Shahrizor region within the province of Sulaymaniyah in Iraqi Kurdistan are bringing to light new information on the region’s social and socio-ecological development. This paper summarises two seasons of work by researchers from German, British, Dutch, and Iraqi-Kurdish institutions working in the survey region. Palaeoenvironmental data have determined that during the Pleistocene many terraces developed which came to be occupied by a number of the larger tell sites in the Holocene. In the sedimentary record, climatic and anthropogenic patterns are noticeable, and alluviation has affected the recovery of archaeological remains through site burial in places. Historical data show the Shahrizor shifting between periods of independence, either occupied by one regional state or several smaller entities, and periods that saw the plain’s incorporation within large empires, often in a border position. New archaeological investigations have provided insight into the importance of the region as a transit centre between Western Iran and northern and southern Mesopotamia, with clear material culture links recovered. Variations between periods’ settlement patterns and occupations are also beginning to emerge. Introduction In 2009, a joint team from the University of Heidelberg and the Directorate of Antiquities of Sulaymaniyah initiated an archaeological survey in the province of Sulaymaniyah, Iraq, in the region of the Shahrizor Plain. Since 2011, the Shahrizor Survey Project (SSP) has been joined by staff from University College London, focusing on historical and palaeoenvironmental research, and from Leiden University, investigating prehistoric periods.2 The survey area lies in the east of the province near the border with Iran. -
Microscopy Characterization of Silica-Rich Agrowastes to Be Used in Cement Binders: Bamboo and Sugarcane Leaves

Conversion of agrowastes into ash is an interesting way of yielding raw material used in the manufacture of low-CO2 binders. Silica-rich ashes are preferred for preparing inorganic binders. Sugarcane leaves (Saccharum officinarum, SL) and bamboo leaves (Bambusa vulgaris, BvL and Bambusa gigantea, BgL), and their corresponding ashes (SLA, BvLA, and BgLA), were chosen as case studies. These samples were analyzed by means of optical microscopy, Cryo-scanning electron microscopy (SEM), SEM, and field emission scanning electron microscopy. Spodograms were obtained for BvLA and BgLA, which have high proportions of silicon, but no spodogram was obtained for SLA because of the low silicon content. Different types of phytoliths (specific cells, reservoirs of silica in plants) in the studied leaves were observed. These phytoliths maintained their form after calcination at temperatures in the 350–850°C range. Owing to the chemical composition of these ashes, they are of interest for use in cements and concrete because of their possible pozzolanic reactivity. -

Human communities made the transition from hunter-foraging to more sedentary agriculture and herding at multiple locations across Southwest Asia through the Early Neolithic period (ca. 10,000-7000 cal. BC). Societies explored strategies involving increasing management and development of plants, animals, materials, technologies, and ideologies specific to each region whilst sharing some common attributes.
