The division of the world into public and private spheres is at the center of a debate over what the government's role should be. This paper seeks to frame the debate between public and private roles regarding security issues. The military has been one area where there has never been a question of nation states outsourcing or privatizing. This paper will touch on the use of mercenaries and then discuss the growing use of corporate entities to supply what were considered to be traditional military activities and objectives.展开更多

The planning process indicates land conversion, increased population, and invasive species arriving in the midst of increased imports are among the major impending threats, especially to terrestrial biological resources. We discuss historical events that have marginalized the contributions of local stakeholders, mistake-ridden planning processes revealing inadequate efforts to safeguard the environment, and compelling evidence that predicts a trajectory targeting imminent damage of terrestrial resources. We contend these developments present a case study within the ecological ethics discipline whereby peacetime military operations push conservation of the environment to the sidelines in the name of national defense. We conclude that conservation of environmental resources is not ancillary to national security, it is integral. Wartime military damage to natural resources is unavoidable, therefore, peacetime military operations should embrace conservation priorities to a greater degree.展开更多

Ever since, there have been many different views over the origin of Japan's road toward war, which mostly concern with Japan's land policy. This paper holds that Japan's land policy was an evolving one and it transformed along the change of its supporters and implementers during different stages. It is mostly a contention about the different strategies on Manchuria and Mongol; the northward or the southward advance faction; the orientations of the radical military occupation or the moderate economic occupation. Interestingly, the development of Japan's postwar policy toward China, especially in the recent years, resembles the evolvement of Japan's land policy in the 19th century. They both show tendency from the economic effort to the military activity.展开更多

The FBCE methodology considers all operational factors in the energy supply chain, including transportation, infrastructure, manpower, maintenance, security protection, and storage of energy. The FBCE concept allows a proper evaluation of the energy costs when assessing different alternatives in military operations and acquisitions. It could also be used to inform decisions on the size and focus of investment in science and technology programs related to the development of efficient military capabilities, alternative fuel sources, and renewable energy solutions. This paper uses cost estimation techniques to formulate the FBCE and focuses on fuel-based military systems and operations. Two case studies using Canadian Forces domestic and deployed operational bases are presented and discussed to demonstrate the methodology.展开更多

The robot is driven by two DC motors, each of which drives one ballast mass, and the two ballast masses are placed symmetrically on the major axis. Compared with the traditional ballast mass principle, the robot has featured high speed, the ability of slope climbing and obstacle overcoming in linear motion. The robot has two inputs and three DOF, which is a nonholonomic and underactuated system. The dynamic model of the robot is constructed, and the linear motion performance of robot in theory is proved by Adams simulation. The control system is briefly introduced, and the performance of the prototype is tested by experiments at last.展开更多

Methods: A canine model of contaminated defect of 1.5 cm in size in the radius was used, in which anti-infective reconstituted bone xenograft or reconstituted bone xenograft was implanted as a primary graft followed by internal fixation. The effectiveness of the two grafting materials in repairing a contaminated segmental defect was compared. Results: The animals which had received implant of anti-infective reconstituted bone xenograft should largely healed defects 6 months after operation while the defects implanted with reconstituted bone xenograft remained unrepaired with bone infection. Conclusions: Besides its strong osteoinductive and osteoconductive activity, anti-infective reconstituted bone xenograft is highly antibacterial and can be used as a primary graft to repair the severely contaminated segmental defect.展开更多

Moreover, it is promising to employ this injector design in military engine, which requires most of the combustion air enters the combustor through injector to reduce smoke emission. However, lean staged injector is prone to combustion instability and extinction in low load operation, so techniques for broadening its stable operation ranges are crucial for its application in real engine.In this work, the LBO performance of a staged injector is assessed and analyzed on a single sector test section.The experiment was done in atmospheric environment with optical access. Kerosene-PLIF technique was used to visualize the spray distribution and common camera was used to record the flame patterns. Emphasis is put on the influence of pilot burner on LBO performance. The fuel to air ratios at LBO of six injectors with different pilot swirler vane angle were evaluated and the obtained LBO data was converted into data at idle condition. Results show that the increase of pilot swirler vane angle could promote the air assisted atomization, which in turn improves the LBO performance slightly. Flame patterns typical in the process of LBO are analyzed and attempts are made to find out the main factors which govern the extinction process with the assistance of spray distribution and numerical flow field results. It can be learned that the flame patterns are mainly influenced by structure of the flow field just behind the pilot burner when the fuel mass flow rate is high; with the reduction of fuel, atomization quality become more and more important and is the main contributing factor of LBO. In the end of the paper,conclusions are drawn and suggestions are made for the optimization of the present staged injector.展开更多

This research is aimed to identify and analyze trauma in antiquity. After a review of bibliography, the first reports of trauma (in Europe) were found in the Greek Epics of Homer. The analysis of these texts showed that injury could be caused to any part of the human body. The main cause of trauma was primarily participation in wars (178 cases), and then participation in sports (6 cases) and other activities (6 cases). This study identified a total of 190 injuries in both Homer epics. The more serious injuries, many of which proved fatal, were observed from participation in military activities.展开更多

Understanding global maritime network dynamics is an initial and critical step in this investigation. This study proposes an automatic identification system(AIS)-based approach to understanding maritime network dynamics before and after international events. In this approach, a spatiotemporal modeling method is introduced to measure the similarity in shipping trends before and after international events. Then, a spatiotemporal analytic framework is proposed to understand the maritime network dynamics by grouping similar situation, and assessing possible indirect effects within a network. Finally, three case studies of international events, military conflict, lifted economic sanctions, and government elections, were used to investigate the observed network dynamics possibly affected by international events. The results indicate that container, tanker, and bulk shipping between India and its connected countries all declined more than 69% after military conflicts between India and Pakistan in August 2015. Tanker shipping between Iran and the United Arab Emirates increased 51% after economic sanctions on Iran were lifted. Container shipping between Sri Lanka and Singapore, Malaysia, and India increased more than 74% after the general election in Sri Lanka. These investigations demonstrate the feasibility of the proposed approach in assessing the possible effects of international events on maritime network dynamics.展开更多

China has a vast territory frequently struck by natural disasters. However, the reality is not optimistic. Poor organization and management during the rescue actions, the lack of large-scale, systematic medical rescue equipment were all great barriers to the outcomes. Mobile hospitals are expected to provide better health care. We were inspired by the concept of mobile hospital. Chongqing Emergency Medical Center, has set up trauma care system since 1988, in which pre- hospital care, intensive care, and in-hospital treatment is fully integrated. As a major advantage, such a system provided assurance of"golden hour" rescue treatment. Providing mobile intensive care and pre- hospital surgical service for severe trauma patients could reduce mortality significantly. Based on the civilian experiences in Chongqing Emergency Medical Center, the mobile emergency (surgical) hospital was developed. 2015 Production and hosting by Elsevier B.V. on behalf of Daping Hospital and the Research Institute of Surgery of the Third Military Medical University.展开更多
