Republicans,Unionists and Jacobites: The 1st Marquess of Tweeddale and the Restoration of the British Parliament

Although John Hay, 1st marquess of Tweeddale, contributed significantly to both the ruthless overthrow of Charles I, and the establishment of the first British parliament in the 1650s, most of his political career was concerned with attempting to re-establish this parliament after it was dissolved at the restoration of Charles II. His first attempt ended in defeat at the hands of the king and the duke of Lauderdale in 1670, but following the overthrow of James VII and II in 1688, Tweeddale tried to persuade the prince of Orange to unite Scotland and England. The prince, however, showed much more interest in securing the crown of Scotland than uniting the two kingdoms. Tweeddale, as lord high commissioner to the Scottish parliament in 1695, responded by passing legislation designed to provoke the English parliament into accepting union. He was also engaged in a jacobite intrigue to restore King James. Tweeddale intended that the restored monarch would be little more than a puppet, who could be used to legitimise what was effectively a republican regime in all but name. By this means the restored parliament would avoid the unpopularity which brought down the first British parliament in 1660. Tweeddale's scheme came to nought, but the technique he employed to manipulate the English parliament, and exploit the jacobite threat, contributed to the restoration of the British parliament ten years after his death.     

Study of coal gas wettability for CO2 storage and CH4 recovery

To quantify and rank gas wettability of coal as a key parameter affecting the extent of CO₂ sequestration in coal and CH₄ recovery from coal, we developed a contact angle measuring system based on a captive gas bubble technique. We used this system to study the gas wetting properties of an Australian coal from the Sydney Basin. Gas bubbles were generated and captivated beneath a coal sample within a distilled water‐filled (pH 5.7) pressurised cell. Because of the use of distilled water, and the continuous dissolution and shrinkage of the gas bubble in water during measurement, the contact angles measured correspond to a ‘transient receding’ contact angle. To take into account the mixed‐gas nature (CO₂, CH₄, and to a lesser extent N₂) of coal seam gas in the basin, we evaluated the relative wettability of coal by CH₄, CO₂ and N₂ gases in the presence of water. Measurements were taken at various pressures of up to 15 MPa for CH₄ and N₂, and up to 6 MPa for CO₂ at a constant temperature of 22°C. Overall, our results show that CO₂ wets coal more extensively than CH₄, which in turn wets coal slightly more than N₂. Moreover, the contact angle reduces as the pressure increases, and becomes < 90° at various pressures depending on the gas type. In other words, all three gases wet coal better than water under sufficiently high pressure.     

Economic geography and the evolution of networks

An evolutionary perspective on economic geography requires adynamic understanding of change in networks. This article explorestheories of network evolution for their use in geography anddevelops the conceptual framework of geographical network trajectories.It specifically assesses how tie selection constitutes the evolutionaryprocess of retention and variation in network structure andhow geography affects these mechanisms. Finally, a typologyof regional network formations is used to discuss opportunitiesfor innovation in and across regions.     

Towards an archaeology and geography of Second World War German munitions storage sites in north-west Europe

This paper reviews the signature characteristics of extant Second World War German army munitions storage landscapes in forested areas of north-west Europe with particular reference to sites in north-west France and the Netherlands. Archaeological survey, aerial photographs and documentary archives show the geography of munitions sites exhibit a regulated pattern of bunker disposition and spacing that is adapted to local road configurations and terrain. Non-hardened bunkers form the predominant feature in munitions depots and conform to a five-/six-fold typology defined by non-invasive survey and excavated examples from the Netherlands. The typology reflects an evolution of storage protocols towards all-round protection from the effects of weather and blast, but also reveals variation in size, structural characteristics and function that poses questions for further study. It is anticipated that these results will be of diagnostic value in future Second World War conflict archaeological survey of German military support structures in formerly occupied territories.     

The Series Formation and Interpretation of Old Testament Literature

A combined review of three volumes in the series Formation and Interpretation of Old Testament Literature. If these volumes intend to give an impression of the discussion among scholars of the Deuteronomistic History, and of the composition of the Pentateuch, the series is a failure, presenting mostly one side of the debate. On the other hand, the articles on the ancient reception history (nothing modern here) are excellent introductions into that discussion.     

Latest developments in rock art recording: towards an integral documentation of Levantine rock art sites combining 2D and 3D recording techniques

This paper presents a further step in the integral documentation of prehistoric rock art, combining 2D and 3D digital recording techniques. Image processing and digital enhancement techniques are an invaluable aid to obtain high quality and accurate 2D recordings, especially when working with faint motifs or complex superimpositions. But what constitutes a real breakthrough is the possibility of combining 2D digital tracings with metric 3D models, providing a whole set of metric outputs that improve our understanding of the motifs in their context and, at the same time, can be used to deliver accurate metric reproductions.     

Experimental study of the effect of variation in in‐situ stress on capillary residual trapping during CO2 geo‐sequestration in sandstone reservoirs

During a geo‐sequestration process, CO₂ injection causes an increase in reservoir pore pressure, which in turn decreases the reservoir net effective stress. Changes in effective stress can change all the reservoir and cap‐rock properties including residual saturations. This article presents the results of an experimental work carried out to understand the potential change in the volumes of residually trapped CO₂, while the porous medium tested underwent change in the net effective stress under in‐situ reservoir conditions of pore pressure and temperature. The experimental results obtained show that an initial 1725 psi (11.9 MPa) decrease in the net effective pressure caused 1.4% reduction in the volumes of residually trapped CO₂, while another 1500 psi (10.3 MPa) reduction caused a further 3.2% drop in the residual saturation of CO₂.     

扬州甘泉山二号墓年代献疑

根据墓葬形制和随葬品特征,可以推定扬州甘泉山二号墓主是东汉晚期而不是东汉早期的广陵王。文献记载也表明,终东汉之世,广陵国的王国地位始终保持,附近发现的"广陵王玺"金印为东汉晚期或使用至东汉晚期的可能性都存在。     

Ceremonial objects or household items? Non‐destructive μ‐XRD2 and μ‐XRF studies on three Neolithic hematite axes from Qatar

Three small stone axes were collected by the joint Qatari‐German South Qatar Survey Project (SQSP) at two places close to the eastern and western coast of Qatar in autumn 2012. Associated with settlement remains, flint artefacts and pieces of ?Ubaid pottery, the implements have been dated to the fifth millennium BCE. Non‐destructive μ‐XRD² and μ‐XRF analyses could, for the first time, prove the use of hematite as the raw material for the manufacture of these tools in Arabia. The absence of major hematite sources in the region and the special characteristics of hematite — a unique metallic shine of polished pieces and the blood‐red colour that appears during the manufacturing process — suggest the highly symbolic character of these objects.
