‘You Load Sixteen Tons, What Do You Get?’. The Jodłowno Hoard (Pomerania, Poland) as Evidence of Long‐Distance Contacts in the Early Iron Age

Archaeometry, EarlyView.
ABSTRACT This study presents multifaceted analyses of metal artefacts from the Jodłowno Hoard (Northern Poland), revealing that the metal originated from Iberian polymetallic ore deposits. Transported as raw ingots via Atlantic maritime routes, this copper was reworked locally into regionally distinctive forms.

Reversal in the Trend of Global Anthropogenic Sulfur Emissions [PDF]

Global anthropogenic sulfur emissions increased until the late 1980s. Existing estimates for 1995 and 2000 show a moderate decline from 1990 to 1995 or relative stability throughout the decade.

The First Archaeomagnetic Age at Tiwanaku and Implications for Dating Andean Metallurgical Furnaces

Archaeometry, EarlyView.
ABSTRACT This paper presents the first archaeomagnetic dating at Tiwanaku (Andean Altiplano). We compared the geomagnetic field values recorded by a metallurgical furnace against an updated SHAWQ2k‐SH global model and a regional intensity curve, both of which include, for the first time, high‐quality intensity data from the Southern Hemisphere.

Frequency Restoration Reserve Control Scheme with Participation of Industrial Loads

, 2013
In order to accommodate larger amounts of renewable energy resources, whose power output is inherently unpredictable, there is an increasing need for frequency control power reserves. Loads are already used to provide replacement reserves, i.e.

An Archaeometallurgical Investigation on Some Archaeological Metal Finds From the Sasanian Site of Jahāngir, Western Iran

Archaeometry, EarlyView.
ABSTRACT Twelve metal artifacts from recent excavations at the Sasanian archaeological site of Jahāngir in western Iran have been analyzed. These items include both decorative and utilitarian artifacts. The samples were examined using micro‐X‐ray fluorescence (μ‐XRF), scanning electron microscopy with energy‐dispersive X‐ray spectroscopy (SEM‐EDS), and

Medicine for the Material World

Archaeometry, EarlyView.
ABSTRACT It is clear that many of the inorganic materials of antiquity have been used both as medicines for human ills and also as agents in technological processes. This paper speculates that there might have been a stronger link between these two functions in the past, based on the concept of “active agents”—materials that are efficacious at curing ...

A metallurgical route to solar-grade silicon [PDF]

The aim of the process is to produce silicon for crystallization into ingots that can be sliced to wafers for processing into photovoltaic cells. If the potential purity can be realized, the silicon will also be applicable for ribbon pulling techniques ...

The slow emergence of the rational investor: Grain markets and grain storage of rural estates in western Germany, eighteenth and early nineteenth centuries

The Economic History Review, EarlyView.
Abstract We develop new datasets of monthly grain prices in 14 urban markets and of the storage and marketing of grain by 5 rural estates located in western Germany between the late seventeenth century and c. 1860. We explore whether observed patterns of monthly prices, sales, and storage of grain are consistent with the rational competitive storage ...
