Mesopotamia: The Old Assyrian Period
No full textThe first part by Klaas Veenhof "The Old Assyrian Period" is a critical overview of our knowledge of and at the same time an introduction to the study of the Old Assyrian Period (first two centuries of the 2nd mill. B.C.), as we know it from discoveries in ancient Assur and in particular from the cuneiform archives of the Old Assyrian traders living in an commercial colony (called karum) in the lower town of ancient Kanesh (modern Kültepe) in Central Anatolia. The first chapters establish what "Old Assyrian" is and analyze the chronology and the available sources (material and written). There follows a critical sketch of the publications of and research on the Old Assyrian sources, subdivided in a dozen thematic studies. After a sketch of Old Assyrian history, follows an overview of "the Old Anatolian scene", which deals with the cities, local rulers and the about 40 Old Assyrian commercial settlements in Northern Mesopotamia and Anatolia. A special chapter analyzes the important Old Assyrian commercial treaties. The contribution ends with a detailed presentation of the Anatolian titles and officials and the religious festivals and agricultural seasons that figure as terms of payments in Anatolian debt-notes.
The second part by Jesper Eidem "Apum: A Kingdom on the Old Assyrian Route" summarises recent evidence for the history of northern Syria during the period contemporary with the late phase of the Old Assyrian trade. To the detailed study of the sources an Appendix of important texts is added. The book is fully indexed (subjects, texts, geographical names, kings and rulers, gods and temples, persons, Assyrian words) and contains a extensive bibliography

Experimental ion mobility measurements in Ne-CF
No full textIn this paper we present the results of the ion mobility measurements made in gaseous mixtures of neon with carbon tetrafluoride (Ne-CF) at a total pressure 8 Torr (10.6 mbar) and for low reduced electric fields in the 10 to 25 Td range (2.4–6.1 kV cmbar), at room temperature. The time-of-arrival spectra revealed only one peak, which was attributed to CF. The reduced mobilities obtained from the peak centroid of the time-of-arrival spectra are presented for Ne concentrations in the 5%–95% range
A large area 100 channel Picosec Micromegas detector with sub 20 ps time resolution
No full textThe PICOSEC Micromegas precise timing detector is based on a Cherenkov
radiator coupled to a semi-transparent photocathode and a Micromegas
amplification structure. The first proof of concept single-channel small area
prototype was able to achieve time resolution below 25 ps. One of the crucial
aspects in the development of the precise timing gaseous detectors applicable
in high-energy physics experiments is a modular design that enables large area
coverage. The first 19-channel multi-pad prototype with an active area of
approximately 10 cm suffered from degraded timing resolution due to the
non-uniformity of the preamplification gap. A new 100 cm detector module
with 100 channels based on a rigid hybrid ceramic/FR4 Micromegas board for
improved drift gap uniformity was developed. Initial measurements with 80 GeV/c
muons showed improvements in timing response over measured pads and a time
resolution below 25 ps. More recent measurements with a new thinner drift gap
detector module and newly developed RF pulse amplifiers show that the
resolution can be enhanced to a level of 17~ps. This work will present the
development of the detector from structural simulations, design, and beam test
commissioning with a focus on the timing performance of a thinner drift gap
detector module in combination with new electronics using an automated timing
scan method

Experimental ion mobility measurements in pure iCH10 and Ar-iCH mixtures
No full textIn this paper we present the results of the ion mobility measurements made in pure isobutane (iCH) and in mixtures with argon (Ar-iCH) for a total pressure of 8 Torr (10.6 mbar) and for low reduced electric fields in the 10 Td to 45 Td range (2.4–10.8 kVcmbar), at room temperature. The reduced mobilities, obtained from the peak centroid of the time-of-arrival spectra, are presented for Ar concentrations in the 5%–95% range
Multi-GEM detectors in high particle fluxes
No full textGaseous Electron Multipliers (GEM) are well known for stable operation at high particle fluxes. We present a study of the intrinsic limits of GEM detectors when exposed to veiy high particle fluxes of the order of MHz/mm2. We give an interpretation to the variations of the effective gain, which, as a function of the particle flux, first increases and then decreases. Wre also discuss the reduction of the ion back-flow with increasing flux. We present measurements and simulations of a triple GEM detector, describing its behaviour in terms of accumulation of positive ions that results in changes of the transfer fields and the amplification fields. The behaviour is expected to be common to all multi-stage amplification devices where the efficiency of transferring the electrons from one stage to the next one is not 100%
Towards future-proof selection procedures in Urban Area Devlopment: Improving decision making regarding selection processes for municipal land sale procedures to decrease transaction costs
No full textOver the last few years several documents have been published about the need for more efficient and cheaper selection processes in municipal land sale procedures. The current costs of selection are often considered too high. New, light selection methods−in which a partner is chosen based on a vision instead of a design−are suggested as a solution. However little research has been conducted about how to choose a fitting process to sell municipal land. Therefore the research question of this thesis is: ‘How can decision making regarding selection processes for municipal land sale procedures be improved to decrease transaction costs for public and private parties involved.’ A basic framework for the research was set up by performing a literature study. Subsequently, a document review was conducted and interviews were held to study two specific cases. Additionally, several general examples of processes in competitive land sale procedures that raised transaction costs were explored. The literature review and the empirical review have led to a synthesis that has set the foundation for a framework for municipalities to make improve decision making for the design of competitive land sale procedures. This has led to the conclusion that there is not a single optimal solution. Multiple factors have to be considered in light of the specific case when choosing a fitting process for a competitive land sale procedure. From this research it is deducted that it is advisable to select one process as a starting point based on a balance between goals and transaction costs for the specific plot. From this starting point municipalities can use transaction cost theory to improve cost efficiency of the preferred procedure to come to an optimal selection design for a successful competitive land sale procedure.Architecture, Urbanism and Building Sciences | Management in the Built Environmen
