Swedish–Finnish naval cooperation in the Baltic Sea: motives,prospects and challenges

Recently, Finland and Sweden decided to substantially deepen their defence cooperation and this project involves creating a bilateral standing Naval Task Group (SFNTG). The present article aims at examining the deepening naval cooperation between Finland and Sweden from a regional integration perspective, focusing on its motives, current challenges and future prospects. Driven by perceptions of common challenges and desires for cost-effectiveness, and strengthened by recent successes on sea surveillance and a combined Amphibious Task Unit, the bilateral project has considerable potential to achieve success. To fulfil its objectives, substantial legal changes in both countries are required to allow the use of force on each other’s territorial waters. To cater for the requirement of not conflicting with EU, NORDEFCO or NATO cooperations, the bilateral Task Group must operate according to NATO standards and by using English as the language in command and control. The costs of adjusting the naval units to NATO’s technical requirements are far from negligible and this issue still remains to be solved. If Finland and Sweden manage to incorporate new policies, common structures and common organisational norms among their navies, an even deeper integration, as in Belgium and the Netherlands, are conceivable.

紊流时输油管道油流静电带电计算研究

对紊流条件下输油管道内油流静电带电的计算进行了研究。在合理简化紊流扩散系数和油流速度的基础上,推导出油内有关油流带电的电荷输运方程的解析解,并且根据该解析解导出了冲流电流计算公式。该计算公式同时适用于所有电导率范围内液体介质冲流电流的计算。最后利用文中推出的计算公式对一实验油道的油流带电进行了计算,结果显示公式得到的值和实验值非常吻合。     

The Evolution and Significance of the 1972 Incidents at Sea Agreement

As a consequence of the rapid growth of Soviet maritime power during the 1960s, hazardous incidents at sea and in the air became a regular part of the Cold War. Eventually, both Washington and Moscow came to recognize the importance of an agreement limiting this perilous set of interactions, resulting in the Incidents at Sea Agreement that was signed in May 1972. The set of rules and procedures agreed upon helped to calm tensions in subsequent crises and provides ample lessons for placing reasonable limits on other tense maritime rivalries.     

“GOOD COP/BAD COP” AS A MODEL FOR NONPROLIFERATION DIPLOMACY TOWARD NORTH KOREA AND IRAN

Scholarly and popular literature in the recent past has framed nonproliferation diplomacy toward both Iran and North Korea as an example of “good cop/bad cop,” a social-psychological strategy borrowed from law enforcement to describe a process for forcing a confession by subjecting a target to stressful emotional contrast. This article examines those two cases, roughly covering the period since 2003, when the most recent attempts to deal with the Iranian and North Korean proliferation threats began, in light of criteria for employment of the good cop/bad cop strategy. There is some evidence that within the framework of the six-party talks with North Korea and within the framework of the EU-3-U.S. diplomacy toward Iran, the players seeking nonproliferation have adopted good cop/bad cop roles to that end. The article concludes, however, that while there are similarities to the interrogation room technique, the complexity of the international political environment as compared to the interrogation room has prevented the states involved from successfully adopting or effectively exploiting good and bad cop roles. Substantial and exploitable differences of interest among them, and the availability of alternative “escape routes” for the target state, raise serious questions about the applicability of the good cop/bad cop strategy to these two nonproliferation cases, and even about its applicability in future nonproliferation challenges.     

The properties of Sn–Zn–Al–La fusible alloy for mitigation devices of solid propellant rocket motors

The Al and La elements are added to the Sn9Zn alloy to obtain the fusible alloy for the mitigation devices of solid propellant rocket motors. Differential scanning calorimetry (DSC), metallographic analysis, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), tensile testing and fracture analysis were used to study the effect of Al and La elements on the microstructure, melting characteristics, and mechanical properties of the Sn9Zn alloy. Whether the fusible diaphragm can effectively relieve pressure was investigated by the hydrostatic pressure at high-temperature test. Experimental results show that the melting point of the Sn9Zn-0.8Al0·2La and Sn9Zn–3Al0·2La fusible alloys can meet the predetermined working temperature of ventilation. The mechanical properties of those are more than 35% higher than that of the Sn9Zn alloy at −50 °C–70 °C, and the mechanical strength is reduced by 80% at 175 °C. It is proven by the hydrostatic pressure at high-temperature test that the fusible diaphragm can relieve pressure effectively and can be used for the design of the mitigation devices of solid propellant rocket motors.     

Nicholas John Spykman,the Balance of Power,and International Order

Nicholas John Spykman was probably America’s finest geopolitical theorist of the twentieth century, even though he was an active participant over the course only of five years (1938–43). He is rightly viewed as a worthy intellectual successor to Sir Halford Mackinder in Britain. Spykman originated the (Eurasian) Rimland concept, which is of continuing political and strategic utility today. He was controversial and notably outspoken while his writings make it quite clear that his concern with the acquisition of power was contextualised by serious concerns for world order.
