An investigation of the system efficiency requires a special approach in terms of its level, content and interrelations with an external environment.In this regard logistic systems are rather DONG QUAI complicated that consist of a number of service sub-systems and designed at various levels.Such system complexity requires a development of an effic
In developed countries, tuberculosis remains a health care challenge due to human immunodeficiency virus (HIV) and immigration from endemic regions.The Centers Bedside Crib for Disease Control and Prevention reported 9557 new cases in 2015, with extrapulmonary involvement in 20.2% of the cases.We present a 33-year-old woman from Cape Town, South Af
By its age and principles, Babylonian law has drawn attention of all epochs, laying at the basis of scientific development of modern law.The regulation, more than 4000 years ago, of property, family, obligations, public administration, succession, probation principle, represents the proof that the institutions which today regulate these aspects, ha
In this study, a new method for manipulating energy flow in a 3D vector field is proposed.In this method, an Bridge Pins azimuthally-polarized beam with a noncanonical vortex, the X-type vortex, is focused in a high-numerical aperture system.It is found that, instead of the invariance of the energy flow which is characteristic of the traditional vo
Abstract Climate events that break records by large margins are a threat to society and ecosystems.Climate change is expected to increase the probability of such events, but quantifying these probabilities is challenging due to natural variability and limited data availability, especially for observations and very rare extremes.Here we estimate the
