    The Stephen R. Covey\u27s book β€œThe Seven Habits of Highly Effective People” tells about ways to increase individuals’ effectiveness and make them more successful. To accomplish these goals, the author proposes the practice of seven main principles or habits. These include: being proactive; beginning with the end in mind; putting first things first; thinking win-win; seeking first to understand rather than to be understood; synergizing; and sharpening the saw

    Are rotating strange quark stars good sources of gravitational waves?

    We study the viscosity driven (Jacobi-like) bar mode instability of rapidly rotating strange stars in general relativity. A triaxial, "bar shaped" compact star could be an efficient source of continuous wave gravitational radiation in the frequency range of the forthcoming interferometric detectors. We locate the secular instability point along several constant baryon mass sequences of uniformly rotating strange stars described by the MIT bag model. Contrary to neutron stars, strange stars with T/|W| (the ratio of the rotational kinetic energy to the absolute value of the gravitational potential energy) much lower than the corresponding value for the mass-shed limit can be secularly unstable to bar mode formation if shear viscosity is high enough to damp out any deviation from uniform rotation. The instability develops for a broad range of gravitational masses and rotational frequencies of strange quark stars. It imposes strong constraints on the lower limit of the frequency at the innermost stable circular orbit around rapidly rotating strange stars. The above results are robust for all linear self-bound equations of state assuming the growth time of the instability is faster than the damping timescale. We discuss astrophysical scenarios where triaxial instabilities (r-mode and viscosity driven instability) could be relevant in strange stars described by the standard MIT bag model of normal quark matter. Taking into account actual values of viscosities in strange quark matter and neglecting the magnetic field we show that Jacobi-like instability cannot develop in any astrophysicaly interesting temperature windows. The main result is that strange quark stars described by the MIT bag model can be accelerated to very high frequency in Low Mass X-ray binaries if the strange quark mass is ~ 200 MeV or higher.Comment: 15 pages, 10 figures, to appear in Astronomy and Astrophysic

    Lower limits on the maximum orbital frequency around rotating strange stars

    Observations of kHz quasi-periodic oscillations (QPOs) in the X-ray fluxes of low-mass X-ray binaries (LMXBs) have been used in attempts to constrain the external metric of the compact members of these binaries, as well as their masses and the equation of state of matter at supranuclear denisties. We compute the maximum orbital frequency of stable circular motion around uniformly rotating strange stars described by the MIT bag model. The calculations are performed for both normal and supramassive constant baryon mass sequences of strange stars rotating at all possible rates. We find the lower limits on the maximum orbital frequency and discuss them for a range of masses and for all rotational frequencies allowed in the model considered. We show that for slowly and moderately rotating strange stars the maximum value of orbital frequency can be a good indicator of the mass of the compact object. However, for rapidly rotating strange stars the same value of orbital frequency in the innermost stable circular orbit is obtained for stars with masses ranging from that of a planetoid to about three solar masses. At sufficiently high rotation rates of the strange star, the rotational period alone constrains the stellar mass to a surprisingly narrow range.Comment: 9 pages, 5 figures, accepted by A&

    Subject. The high resource potential of the Krasnoyarsk Territory generates a topical and rapidly growing demand for its territory for the purposes of its multifunctional economic use. The variety of loads on the regional ecosystems and the desire to minimize the risk of their destruction requires a comprehensive planning and targeted use of the territories of the region. Objectives. To substantiate an integrated approach and the construction of the index, reflecting the sustainable development of natural resource areas. To create an administrative tool based on statistical data, without expert estimates and subjective judgments, in order to make decisions about the possibility of placing production facilities in the selected municipality from a position of the three dimensions: ecology, society, economy. Methodology. Using statistical and econometric methods, this paper substantiates the construction of the index that is an aggregated integral index of environmental sustainability for municipalities of the Krasnoyarsk Territory. The technique is applicable to various scales of territorial zoning. The scale is determined by the availability of reliable statistical information for objects of different sizes (municipality, city district, industrial zones). Results. The article highlights the issues of environmental economic zoning of resource areas on the basis of the integral index of ecological and economic stability, taking into account environmental, economic and social factors in the context of municipalities (urban districts, municipal districts). Besides, the article shows the possibilities of environmental economic zoning for the determination of the boundaries of priority and recommended functional areas, because the local areas of institutional conflict environmental management are located precisely there. A draft of Krasnoyarsk Territory Government Resolution β€˜On approval of a regional order and methods of environmental economic zoning of the Krasnoyarsk Territory’ is developed for the purposes of balanced social, ecological and economic development of the natural and resource region Conclusion. The developed approach can be used to ensure the sustainable development of territories of intensive economic development, to substantiate socio-economic development programs of the Krasnoyarsk Territory and its municipalities, to carry out ecological and economic assessment and decision-making about the possibility to implement major investment projectsΠŸΡ€Π΅Π΄ΠΌΠ΅Ρ‚.
