Plant remains from archaeological sites reflect many aspects of the relationship between people, plants, and the environment in which they lived. Plant macroremains—seeds and wood that are visible without a microscope—can address a wide range of questions. The most basic include what crops were grown? What was used for fuel? Do any of the plants come from distant lands? Examples from fourth and...

NGIOSPERM gametogenesis, particularly on the male side, is highly susA ceptible to disturbance by either environment o r genotype. Exemplary of environmental agents, sodium a,P-dichloroisobutyrate disrupts pollen development, the effect being sufficiently specific and complete to warrant use of this chemical for purposes of emasculation (EATON 1957). Instances of genetic control are commonplace...

In this study, we compared cross-bred dairy cows in the Susa Valley (Piedmont, northern Italy), reared either near a high-temperature steel production plant (Farms A and B) or in an industry-free area (control). Exposed cows (n = 36) were selected based on mean bulk milk toxic equivalent values of polychlorodibenzodioxins (PCDDs) and dioxin-like (DL) polychlorobiphenyls (PCBs) and polychlorodib...

Just over 5,000 years ago, the earliest cities flourished in Mesopotamia and western Iran. One explanation that has been considered is that making these areas with their seasonal alternations of flooding and drought amenable to agriculture required a complex infrastructure for water retention and irrigation. Thus, only a critical mass of workforce and a certain level of organisation could make ...

Discoveries concerning the important roles of glycoconjugates in a variety of biological processes have led to an increased demand for efficient synthetic methodologies adaptable for their large-scale production.1 Compared to chemical synthesis, an enzymatic approach utilizing glycosyltransferases has been proven more efficient in the production of complex carbohydrates.2 Despite the increasing...

Size, age, and spatial structures were studied in a mixed, multilayered forest located in the Upper Susa Valley in Piedmont, Italy, using complete stem mapping, dendrochronology, and spatial analysis on a 1-ha permanent plot. All trees with a diameter >4 cm at 50 cm height (991) and stumps (322) were mapped, measured, and cored. The 639 cross-dated samples were used to reconstruct the disturban...

Abstract This article introduces a methodology to evidence the current attractiveness level of Italian high-speed railway stations in GIS environment, involving station services and flow parameters. The model has been relevant detect with lower attractive capacity, afterward, implement attractivity, work proposed employing coworking spaces strategy as service station. Coworking produce benefits...
