It is established that today there is an increase in the number of both international and local conflicts, increase in the share of conflicts, which are at the stage of violent crisis; and that the main causes of conflicts in the world are ideological differences, use of national power, resources
Cosmology and Static Spherically Symmetric solutions in D-dimensional Scalar Tensor Theories: Some Novel Features
We consider scalar tensor theories in D-dimensional spacetime, D \ge 4. They
consist of metric and a non minimally coupled scalar field, with its non
minimal coupling characterised by a function. The probes couple minimally to
the metric only. We obtain vacuum solutions - both cosmological and static
spherically symmetric ones - and study their properties. We find that, as seen
by the probes, there is no singularity in the cosmological solutions for a
class of functions which obey certain constraints. It turns out that for the
same class of functions, there are static spherically symmetric solutions which
exhibit novel properties: {\em e.g.} near the ``horizon'', the gravitational
force as seen by the probe becomes repulsive.Comment: Revtex. 21 pages. Version 2: More references added. Version 3: Issues

The Cauchy problem of scalar-tensor theories of gravity
The 3+1 formulation of scalar-tensor theories of gravity (STT) is obtained in
the physical (Jordan) frame departing from the 4+0 covariant field equations.
Contrary to the common belief (folklore), the new system of ADM-like equations
shows that the Cauchy problem of STT is well formulated (in the sense that the
whole system of evolution equations is of first order in the time-derivative).
This is the first step towards a full first order (in time and space)
formulation from which a subsequent hyperbolicity analysis (a well-posedness
determination) can be performed. Several gauge (lapse and shift) conditions are
considered and implemented for STT. In particular, a generalization of the
harmonic gauge for STT allows us to prove the well posedness of the STT using a
second order analysis which is very similar to the one used in general
relativity. Some spacetimes of astrophysical and cosmological interest are
considered as specific applications. Several appendices complement the ideas of
the main part of the paper.Comment: 29 pages Revtex; typos corrected; references added and updated; a

Computational psychiatry approach to stigma subtyping in patients with mental disorders: explicit and implicit internalized stigma
BACKGROUND: Psychiatric stigma has potentially controversial effects on patients health-related behaviors. It appears that both stigmatization and motivation in psychiatric patients are heterogeneous and multi-dimensional, and that the relationship between stigma and treatment motivation may be more complex than previously believed.
AIM: To determine psychiatric stigma subtypes as they relate to treatment motivation among inpatients with various mental disorders.
METHODS: Sixy-three psychiatric inpatients were examined by the Treatment Motivation Assessment Questionnaire (TMAQ) and the Russian version of Internalized Stigma of Mental Illness scale (ISMI). K-Means cluster and dispersion analysis were conducted.
RESULTS: Cluster 3 (25 subjects) was the least stigmatized. Cluster 1 (18 subjects) showed an explicit stigma. Cluster 2 (20 subjects) showed an implicit stigma that took the form of the lowest treatment motivation compared to other clusters. Implicitly stigmatized patients, in contrast to explicitly stigmatized individuals, showed a decline in 3 out of 4 TMAQ factors (Mean dif.=1.051.67).
CONCLUSION: Cooperation with doctors, together with reliance on ones own knowledge and skills to cope with the disorder, might be the way to overcome an internalized stigma for patients with mental disorders
No hair for spherical black holes: charged and nonminimally coupled scalar field with self--interaction
We prove three theorems in general relativity which rule out classical scalar
hair of static, spherically symmetric, possibly electrically charged black
holes. We first generalize Bekenstein's no--hair theorem for a multiplet of
minimally coupled real scalar fields with not necessarily quadratic action to
the case of a charged black hole. We then use a conformal map of the geometry
to convert the problem of a charged (or neutral) black hole with hair in the
form of a neutral self--interacting scalar field nonminimally coupled to
gravity to the preceding problem, thus establishing a no--hair theorem for the
cases with nonminimal coupling parameter or . The
proof also makes use of a causality requirement on the field configuration.
Finally, from the required behavior of the fields at the horizon and infinity
we exclude hair of a charged black hole in the form of a charged
self--interacting scalar field nonminimally coupled to gravity for any .Comment: 30 pages, RevTeX. Sec.IV corrected, simplified and shortened.

Classical Yang-Mills Black hole hair in anti-de Sitter space
The properties of hairy black holes in Einstein–Yang–Mills (EYM) theory are reviewed, focusing on spherically symmetric solutions. In particular, in asymptotically anti-de Sitter space (adS) stable black hole hair is known to exist for frak su(2) EYM. We review recent work in which it is shown that stable hair also exists in frak su(N) EYM for arbitrary N, so that there is no upper limit on how much stable hair a black hole in adS can possess
Lifshitz black holes in Brans-Dicke theory
We present an exact asymptotically Lifshitz black hole solution in
Brans-Dicke theory of gravity in arbitrary dimensions in presence of
a power-law potential. In this solution, the dynamical exponent is
determined in terms of the Brans-Dicke parameter and . Asymptotic
Lifshitz condition at infinity requires , which corresponds to
. On the other hand, the no-ghost condition
for the scalar field in the Einstein frame requires . We
compute the Hawking temperature of the black hole solution and discuss the
problems encountered and the proposals in defining its thermodynamic
properties. A generalized solution charged under the Maxwell field is also
presented.Comment: 32 pages, no figure. v2: revised version. Section 3.1 and Appendix B

SYSTEM OF ANAESTHETIC SUPPORT AT LARGE JOINT REPLACEMENT SURGERIES
The operation of total endoprosthesis replacement of large joints is associated with several anesthetic problems. Solving these problems ensures the safety of these highly traumatic operations and requires the solution of the following anesthetic tasks in the perioperative period: high degree of antinociceptive protection of patients with effective relaxation of the surgical intervention area; prevention of fatty hyperglobulinemia; decrease in the volume of perioperative hemorrhage and prophylaxis of thrombogenic complications. We developed our own program of anesthetic maintenance at major joints replacement. The components of the program are: the type of anesthesia - spinal anesthesia preservation of spontaneous respiration; our method of fat globulinemia prevention, based on maintaining the functional stability of the hepatocyte; our own method of replacement of peri-operative blood loss, based on the additional principle of "normalization of the oncotic blood pressure". Before the operation, patients receive a solution of tranexamic acid at a dose of 10 mg/kg of body mass to inhibit proteolysis (blood preservation technology). This method provides a "dry" operating field, reducing intraoperative hemorrhage. In the early postoperative period (5 hours after the surgery), under the control of whole blood clotting time, patients receive low molecular weight heparin Clexane at a therapeutic dosage of 1 mg/kg of body weight. This provides effective prevention of thrombogenic complications. The application of the developed technique shows its high clinical effectiveness. Over the past 5 years, 5,800 operations for large joint prosthetics have been performed, including 3,200 total hip replacement operations, 2,600 total knee replacement operations. There were no complications with a fatal outcome, in 5 cases fatty hyperglobulinemia was noted, which was stopped by the own method of treatment. There are no thrombogenic complications
