Abstract: In this paper the Hamiltonian structure of magnetic lines is studied in many ways. First it is used vector analysis for defining the Poisson bracket and Casimir variable for this system. Second it is derived Pfaffian equations for magnetic field lines. Third, Lie derivative and derivative of Poisson bracket is used to show structure of this system. Finally, it is shown Nambu structure of the magnetic field lines. [Copyright &y& Elsevier]

We used radiotelemetry to investigate resting sites habitat selection by introduced eastern cotton-tail (Sylvilagus floridanus) and native European hare (Lepus europaeus) under sympatric conditions. We tracked 24 hares and 34 cottontails in a protected area of northwestern Italy. Hares were found in different sites every week, while cottontails used the same site for two weeks, and occasionally for longer. It is supposed that this periodic nest switching reduces the risk of predation and parasitism. Hares and cottontails forms were located in different habitats and characterized by dense vegetation cover near the ground. This cover increased from winter to summer in both species, while in autumn it continued to increase in cottontails only, and decreased in hares. Cottontails selected shrubby habitats near the river, and avoided crop fields in all seasons. Hares were more adaptive in their search, using high herbs and shrubs all year round, wheat fields in spring, maize in spring and summer, and stubbles in winter. Arguably, partial niche differentiation is necessary to allow the coexistence of similar species. In our study area, hares and cottontails differentiated in the use of resting sites habitats, presumably so as not to compete in this part of their ecological niche. [ABSTRACT FROM AUTHOR]

The article focuses on the vaccines and public health in China. Topics discussed including the well-developed system of vaccines production and sale in China; flaws in the transport and management of vaccines led to a large number of expired medicines; and according to current regulations vaccines produced by Changsheng are not able to be defined as fake.

The article reports that in the court case American Bankers Ins. Co. v. Tellis, Alabama Supreme Court held that policyholders are required to arbitrate even if they have not signed, read or receive insurance forms that carried arbitration agreements. It was said that arbitration provision need not be in insurance application which was signed, rather it was mentioned in the policy that it is not complete without declaration page which contained the arbitration clause.
