In the last few years, the concepts of fractional calculus were frequently applied to other disciplines. Recently, this subject has been extended in various directions such as signal processing, applied mathematics, bio-engineering, viscoelasticity, fluid mechanics, and fluid dynamics. In fluid dynamics, the fractional derivative models were used widely in the past for the study of viscoelastic materials such as polymers in the glass transition and in the glassy state. Recently, it has increasingly been seen as an efficient tool through which a useful generalization of physical concepts can be obtained. The fractional derivatives used most are the Riemann--Liouville fractional derivative and the Caputo fractional derivative. It is well known that these operators exhibit difficulties in applications. For example, the Riemann--Liouville derivative of a constant is not zero. We deal with so called temporal fractional derivative as a prototype of general fractional derivative. We prove the global strong solvability of a linear and quasilinear initial-boundary value problems with a singular complete monotone kernels. Our main tool is a theory of evolutionary integral equations. An abstract fractional order differential equation is studied, which contains as particular case the Rayleigh–Stokes problem for a generalized second-grade fluid with a fractional derivative model. This paper concerns with an initial-boundary value problem for the Navier--Stokes--Voigt equations describing unsteady flows of an incompressible viscoelastic fluid. We give the strong formulation of this problem as a nonlinear evolutionary equation in Sobolev spaces. Using the Galerkin method with a special basis of eigenfunctions of the Stokes operator, we construct a global-in-time strong solution in two-dimensional domain. We also establish an $L_2$ decay estimate for the velocity field under the assumption that the external forces field is conservative.

Slovenska vojska poleg nacionalne obrambe opravlja naloge v mednarodnih operacijah in na misijah v zahtevnih podnebnih in geografskih razmerah zunaj območja držav članic Nata in EU. Zavezniške sile, ki opravljajo svoje poslanstvo na ozemljih zunaj Natovega območja, so lahko izpostavljene različnim dejavnikom tveganja, ki vplivajo na njihovo zdravje. Za njihovo ustrezno zdravstveno zaščito je treba sprejeti in izvajati učinkovit program, ki naj bo namenjen tako zdravstvenemu osebju kot poveljnikom. Strokovno zdravstveno osebje pridobiva zdravstvene podatke, na primer ocenjuje okoljske in zdravstvene vire ogrožanja, prepozna tveganja in izdela analizo groženj, ter jih vključuje v upravljanje tveganj. MEDINT ima pomembno vlogo v razmerju med zdravstvenim sistemom in krovno obveščevalno dejavnostjo, uporablja zakonitosti njenega obveščevalnega ciklusa, saj se na nekaterih stopnjah obveščevalni ciklus MEDINT vključuje v obveščevalni ciklus krovne obveščevalne dejavnosti. Končni obveščevalni proizvod MEDINT, ki temelji na oceni zdravstvene ogroženosti, podpira poveljnikov namen in operacijo. In addition to providing for national defence, the Slovenian Armed Forces perform tasks in demanding climatic and geographical conditions in international operations and missions outside the territory of NATO and EU Member States. Allied forces performing their mission in the territories outside the NATO area may be exposed to various threats that affect their health. For the protection of the forces` health, it is necessary to adopt and implement an effective program, which should be aimed, both, at healthcare personnel as well as commanders. Professional medical staff obtains medical data, assesses environmental and medical threats, identifies the risks, carries out threat analysis and implements them in risk management. Medical intelligence (MEDINT) plays an important role in the relation between the health system and intelligence activities. It also uses the intelligence cycle to ensure that all available information for making assessments is processed. To be fully efficient MEDINT requires the cooperation of experts from different natural science disciplines (medical, scientific or bio-engineering). The final MEDINT product based on the health threat assessment supports the commander’s intent and the operation as such.
