Keyhole defect production in tubular bone

Fracture characteristics, reported primarily for the cranium, are valuable indicators of bullet direction. A bullet striking the vault tangentially produces an irregular opening, termed a "keyhole defect." with the circular portion of the defect being the initial point of impact. Identifying this feature in tubular bone (long bone) can also demonstrate bullet direction and the position of the bone at the time of the shooting. This case study involving a tangential shot (i.e., a keyhole fracture) to the humerus demonstrates some of the same fracture mechanics seen in the cranium.

Understanding Havel?

The presented article tries to make sense of Václav Havel, a man of many qualities and professions yet not a professional in the conventional sense of the word. The aim is to offer deeper insight into diverse cognitive elements which formed Havel's political reasoning and attitudes. The idea is to provide an alternative interpretation and get beyond the customary explanations expressed through traditional IR language seeing Havel as a dissident idealist who was pushed by some realist impulses to clearly define real political and later also geopolitical stands. In doing so, the article is divided into three parts. The first part discusses conceptual frameworks (rather than a single framework) within which Have saw and understood the political world. The middle part examines Havel's political agenda, namely the issues of the return to Europe, the German question, and relationships with Russia, the United States and toward multilateral institutions. The final part that utilizes primary data obtained through personal interviews with many Havel's close collaborators presents two faces of Václav Havel: the dramatist and the ideologue.     

The US–Russian security ‘reset’: implications for Central-Eastern Europe and Germany

Abstract

The article examines the reactions of selected European states to the US-performed ‘reset’ in relations with Russia and explores the ways in which they have been adapting to the new set-up. The article is divided into three parts: after the discussion of the substantive continuity and limited change in US foreign and security policy (USFSP), the multilateral and bilateral dimensions of USFSP procedure are examined through John Ruggie's theoretical observations. The second part of the article deals with implications of the USFSP for Central-Eastern European countries. This part begins with a discussion of Russian attempts to wheedle Europe into embracing its plans for new European security architecture. The next section sheds light on the unexpected process of strategic realignment of the region (USA/NATO/EU/CSDP) and simultaneous transformation of the special relationship with the USA into ‘normal life’. The third part of the article tackles the implications of heightened US–Russian bilateralism for Germany. Authors' findings, many of them based on conducted elite interviews, suggest the contrary process, namely Germany's strengthened multilateral commitment to the EU and specifically to European Security and Defence Policy, limiting the bilateral option to energy trade with Russia. What follows are concluding remarks.     

Characterizing the Performance of Pipe Bombs

Pipe bombs of steel or PVC fragment in reproducible patterns when similarly configured. The power of the explosion correlates with number, mass, and size of the fragments recovered, where a large number of small, low‐mass fragments indicate a high‐power event and vice versa. In discussing performance, describing pipe fragmentation pattern by fragment weight distribution mapping (FWDM) or fragment surface area distribution mapping (FSADM) was useful. When fillers detonated, detonation velocities of ~4.4 mm/μs were measured. In such cases, side walls of the pipe were thrown first; the average fragment velocity was ~1000 km/s. In deflagrations, the end cap was first thrown; fragment velocities were only ~240 km/s. Blast overpressures varied; at 10 feet, 2 × 12 inch steel pipes containing ~550 g of detonable mixture produced overpressures of 5–6 psi; similar nondetonating pipes produced less than 2 psi. Maximum fragment throw distances were 250–300 m, with an average of ~100 m.     

Democracy in Spain: Legitimacy, discontent, and disaffection

This article examines changes in perceptions of democracy in Spain over the last two decades. A variety of empirical indicators gleaned from numerous surveys are used to distinguish between democratic legitimacy and political discontent, as well as between this (which includes the well-known indicator of dissatisfaction with the way democracy works) and political disaffection. The article traces the different ways in which these attitudes have evolved in Spain over the last twenty years, and demonstrates that they belong to different dimensions. It also includes the results of two tests showing that these two sets of attitudes are conceptually and empirically distinct: a factor analysis confirms the distinct clustering of the indicators at the, individual level, whilst cohort analysis identifies different patterns of continuity and change across generations.

The continuing relevance of Germany's engine for CEE and the EU

The article looks first into the nature of the relations between Germany and the CEE countries a decade since the accession of the CEE countries to the EU. The relations are characterized as normalised and intensive with diverse levels of closeness and co-operation reflecting of the conceptual and ideological compatibility/differences.Next, the article focuses on the German attitude to the euro zone crisis. Germany has become a hegemon in the rescue effort aimed at stabilisation and economic invigoration of the euro zone. However, German hegemony has developed by default, not by design: her leading position is linked with considerable political and financial costs. Germany moved central stage and took the position of a reluctant hegemon. However, German role is contested internationally (it has not the support of the French government in key areas) as well as internally (particularly by the Federal Constitutional Court and the Bundesbank).The article argues that the new situation makes the German–CEE relations increasingly relevant for both sides. The German leadership of the EU increasing split along the north–south divide requires backing by the Northern group countries to which the CEE in general belongs. Given a number of reasons the CEE countries implement three distinctive strategies of co-operation with Germany in European politics. Also military co-operation, which remained rather limited so far, may receive new impulses, given the financial austerity.     

Legal Irritants: Good Faith in British Law or How Unifying Law Ends Up in New Divergencies

Legal transplant is an unsatisfactory metaphor for describing the transfer of legal rules from one legal system to another. Instead, the metaphor of legal irritant better describes the impact on the legal system, and then a distinction between tight and loose coupling between law and its social context better explains the trajectory of social effects. The example of the importation of the civil law concept of good faith into British law illustrates the co-evolving trajectories of the legal system and tightly coupled social systems which instead of furthering harmonisation of laws produces new divergences as their unintended consequences.
