At the edge of empires: the Noviodunum project, Romania
Kris Lockyear
Archaeology International , 2002, DOI: 10.5334/ai.0607
Abstract: The Roman fortress of Noviodunum on the lower Danube guarded the border of both the Roman and the Byzantine empire against barbaricum – the lands of the so-called barbarians – to the north and east. In a new collaborative project, Romanian archaeologists and colleagues from the Institute of Archaeology and the universities of Cambridge and Southampton are beginning to investigate both the site and its relationship with its hinterland and the wider imperial frontier zone.
Texts in the landscape
James Graham-Campbell,Kris Lockyear
Archaeology International , 1998, DOI: 10.5334/ai.0212
Abstract: The Institute's members of UCL's "Celtic Inscribed Stones" project describe, in collaboration with Wendy Davies, Mark Handley and Paul Kershaw (Department of History), a major interdisciplinary study of inscriptions of the early middle ages from the Celtic areas of northwest Europe.
Rome and Byzantium on the Danube: the Noviodunum Archaeological project 2005–2008
Kris Lockyear,Adrian Popescu,Timothy Sly
Archaeology International , 2008, DOI: 10.5334/ai.1113
Abstract: The fortress of Noviodunum on the lower Danube guarded the border of both the Roman and the Byzantine empires. The Noviodunum Archaeological Project, based in the Institute of Archaeology, is an international collaborative project with the primary aim of investigating the changing economic relations between the fortress, its hinterland and the wider Mediterranean world. The project began in 2000 and the final season of fieldwork will take place in 2009. In this article the directors describe the work of the last four seasons and present preliminary conclusions.
Does the endangered Knysna seahorse, Hippocampus capensis, have a preference for aquatic vegetation type, cover or height?
Peter R. Teske,Jacqueline F. Lockyear,Thomas Hecht,Horst Kaiser
African Zoology , 2011,
Abstract: The Knysna seahorse,Hippocampus capensis, is an endangered teleost confined to three South African estuaries. Its abundance within these systems is low and distributions are patchy. Consequently, monitoring population sizes is labour-intensive. The aim of this study was to establish if Knynsa seahorses are associated with specific regions within the estuaries, on which conservation efforts could concentrate. The relationship of Knysna seahorses with aquatic vegetation was analysed in the Knysna Estuary (the largest of the three estuarine systems inhabited by H. capensis) to determine whether this species shows a preference for a particular plant species, vegetation density or vegetation height. Seahorses were associated with five dominant aquatic plants: Zostera capensis, Caulerpa filiformis, Codium extricatum, Halophila ovalis and Ruppia cirrhosa. Together, these comprised 96% of the submerged objects with which seahorses were associated. The relative abundance of plant species changed along the estuary, but seahorses were present throughout the system, except at the estuary mouth,
Pyranine Fluorescence Quenching for the Characterization of Solutions  [PDF]
Qiuxia Wang, Kris A. Berglund
American Journal of Analytical Chemistry (AJAC) , 2016, DOI: 10.4236/ajac.2016.71005
Abstract: Fluorescence quenching of pyranine by tryptophan, phenylalanine, and nicotinic acid was investigated by using steady state and time resolved fluorescence spectroscopy. On a comparative basis, nicotinic acid is a very strong quencher of pyranine fluorescence, tryptophan is a moderate quencher and phenylalanine is a weak quencher. The strong quenching is the result of the hydrogen bonding complex between pyranine and amine which existed in both tryptophan and nicotinic acid. Contact complex will form between phenylalanine and pyranine which is the reason of quenching of pyranine by phenylalanine. Associates will form in tryptophan and phenylalanine due to the zwitterion +H3NRCOO- or/and hydrogen bond. Higher concentrations favor the formation of aggregates in the supersaturated solution which made the quenching curve different from unsaturated solution dramatically.
Iorio's "high-precision measurement" of frame-dragging with the Mars Global Surveyor
Krogh, Kris
High Energy Physics - Phenomenology , 2007, DOI: 10.1088/0264-9381/24/22/N01
Abstract: In two analyses of orbital data from the Mars Global Surveyor spacecraft, Iorio [1,2] has claimed confirmation of the frame-dragging effect predicted by general relativity. Initially to an accuracy of 6%, and now 0.5%, exceeding the expected accuracy of NASA's Gravity Probe B. It is shown his results come from misinterpreting the MGS data and then altering a key time period.
Cause No Conflict
Kris Borer
Libertarian Papers , 2010,
Abstract: If property is defined as something over which an individual should have exclusive control, then the traditional notion of property must be abandoned. Specifically, the idea that a physical object is someone’s property fails to meet the definition given. This paper examines why an individual should not always have exclusive control over physical things, and, if not objects, what exactly an individual should have exclusive control over.The proposed solution is that property be delineated not by physical boundaries, but by human action. This does not include all action, for scarcity makes certain actions mutually exclusive. Therefore, property is conceived of as proper action, i.e., action consistent with the non-aggression principle. Those physical objects traditionally considered property are then simply means of proper action.The benefits of this change in perspective are then examined with regard to production, exchange, aggression and other related topics.
Risking Aggression: Reply to Block
Kris Borer
Libertarian Papers , 2010,
Abstract: In his paper, “Is There an ‘Anomalous’ Section of the Laffer Curve?”, Walter Block describes some situations in which it appears that a libertarian should violate the non-aggression principle. To rectify this, Block proposes a different perspective on libertarianism which he calls punishment theory. This paper argues that no new theory is needed, as the non-aggression principle can be used to resolve theapparent conundrums.
The Human Body Sword
Kris Borer
Libertarian Papers , 2010,
Abstract: The human body shield problem involves an apparent dilemma for a libertarian, forcing him to choose between his own death and the death of an innocent person. This paper argues that the non-aggression principle permits a forceful response against the property of innocent individuals when a conflict is initiated with that property. In other words, a libertarian may shoot the hostage in order to save himself.
The Determinants of Firm-Level Export Intensity in New Zealand Agriculture and Forestry
Kris Iyer
Economic Analysis and Policy , 2010,
Abstract: This paper investigates the determinants of firm level export intensity in New Zealand’s agriculture and forestry over the period 2000-06. Applying a random effects model, it is uncovered that export intensity is driven by firm productivity and export market diversification. Firm size is found to have a negative effect on export intensity. Sector characteristics do not have an empirically discernible influence.
