The eye of war : military perception from the telescope to the drone
\"This project explores how technologies of perception -- the ability to detect and to avoid detection -- have transformed modern warfare. The book spans from the Renaissance, where the rationalization of vision and space started to influence military strategy, to the present day, where combatants increasingly face off in the perceptual realm of drones and satellites as much as the physical battlefield. Each chapter explores a different perceptual theme: sensing, imaging, mapping and hiding\"-- Provided by publisher.

Well Killing Technology before Workover Operation in Complicated Conditions
Well killing is an important technological stage before conducting workover operation, one of the tasks of which is to preserve and restore the natural filtration characteristics of the bottomhole formation zone (BFZ). Special attention should be paid to the choice of well killing technologies and development of wells in complicated conditions, which include abnormally low reservoir pressure, high oil-gas ratio and carbonate reservoir type. To preserve the filtration characteristics of the productive formation and prevent fluid losses in producing wells during well killing operation, blocking compositions are used. At the same time, an informed choice of the most effective well killing technologies is required. Consequently, there is a need to conduct laboratory physicochemical and coreflood experiments simulating geological, physical, and technological conditions of field development, as similar as possible to actual reservoir conditions. The article presents the results of experimental studies on the development well killing technologies of producing wells during workover operation in various geological, physical, and technological conditions of oil field development. Physicochemical and coreflood laboratory experiments were carried out with the simulation of the processes of well killing and development of wells in reservoir conditions with the use of modern high-technology equipment in the Enhanced Oil Recovery Laboratory of the Department of Development and Operation of Oil and Gas Fields at St. Petersburg Mining University. As a result of the experimental studies, new compositions of well killing and stimulation fluids were developed, which ensure to prevent fluid loss, gas breakthrough, as well as the preservation, restoration and improvement of the filtration characteristics of the BFZ in the conditions of terrigenous and carbonate reservoirs at different stages of oil field development. It is determined that the developed process fluids, which include surfactants (YALAN-E2 and NG-1), have a hydrophobic effect on the porous medium of reservoir rocks, which ultimately contributes to the preservation, restoration and improvement of the filtration characteristics of the BFZ. The value of the presented research results is relevant for practice and confirmed by the fact that, as a result of field tests of the technology for blocking the BFZ with the composition of inverse water–oil emulsion during well killing before workover operation, an improvement in the efficiency of wells operation was obtained in the form of an increase in their oil production rate by an average of 5–10 m3/day, reducing the time required for the well to start operating up to 1–3 days and reducing the water cut of formation fluid by 20–30%.

The morality of drone warfare and the politics of regulation
\"The book discusses the moral and legal issues relating to military drones, focusing on how these machines should be judged according to the principles of just war theory. It not only considers existing drones like the Predator and Reaper but also evaluates the many types of drones in development. It finds that drones are not only morally justifiable but that they have the potential to improve compliance with the principles of just war and international law. Realizing this potential depends on developing a sound regulatory framework, which the book helps to develop by considering what steps governments and military forces should take to promote ethical drone use. It also critically evaluates the arguments against drones to show which should be abandoned and which raise valid concerns that can inform regulations.\"--Back cover.

On the existence of conformal Killing horizons in LRS spacetimes
Let
M
be a locally rotationally symmetric spacetime, and
ξ
a
a conformal Killing vector for the metric on
M
, lying in the subspace spanned by the unit timelike direction and the preferred spatial direction, and with non-constant components. Under the assumption that the divergence of
ξ
a
has no critical point in
M
, we obtain the necessary and sufficient condition for
ξ
a
to generate a conformal Killing horizon. It is shown that
ξ
a
generates a conformal Killing horizon if and only if either of the components (which coincide on the horizon) is constant along its orbits. That is, a conformal Killing horizon can be realized as the set of critical points of the variation of the component(s) of the conformal Killing vector along its orbits. Using this result, a simple mechanism is provided by which to determine if an arbitrary vector in an expanding LRS spacetime is a conformal Killing vector that generates a conformal Killing horizon. In specializing the case for which
ξ
a
is a special conformal Killing vector, provided that the gradient of the divergence of
ξ
a
is non-null, it is shown that LRS spacetimes cannot admit a special conformal Killing vector field, thereby ruling out conformal Killing horizons generated by such vector fields.
