On the Frequency Theorem for Nonperiodic SystemsUsing methods of the theory of nonautonomous linear differential systems, namely exponential dichotomies and rotation numbers, we generalize some aspects of Yakubovich’s Frequency Theorem from periodic control systems to systems with bounded measurable coefficients.

On Constrained Dynamical Systems and AlgebroidsIn 1994, van der Schaft and Maschke defined a(n) (almost) Poisson structure for the study of constrained port controlled Hamiltonian systems as systems obtained by reduction. This note intends to provide a geometrical framework that justifies such construction, based on the use of Lie algebroids, and which extends the work presented in [.].

Pancreatic Fistulas After Exclusion of the Residual Stump in Resections of the Pancreatic Head,Among postoperative pancreatic fistulas we should not forget those following resections of the pancreatic head in which the residual caudal pancreatic stump is excluded from the gastrointestinal tract after the pancreatic ductal system has undergone staghorn occlusion using synthetic resins of various types..

The Large Pine Aphid on Scots Pine in Britain,The large pine aphid, . (Mordvilko), infests a number of pines but is found most commonly on Scots pine (.).. It is widely distributed throughout the Palaearctic, coinciding with the range of its main host plant.. There are also numerous records from North America, where Scots pine has been introduced and grown on a commercial basis.

The Balsam Woolly Adelgid in North America,The balsam woolly adelgid, also known as the balsam woolly aphid, is native to the silver fir (.) forests of central Europe. The insect was introduced into North America around 1900. Although European firs are not seriously affected by this adelgid, North American firs frequently experience either crown dieback or tree death, or both.

Staging and Early Nasoenteral Feeding in Acute PancreatitisThis article on acute pancreatitis (AP) is about staging (mild and severe forms of the disease) and early nasoenteral feeding. The potential impact this is having at present (and probably will have in the future) on the way we are thinking about and managing patients with acute pancreatitis is considerable.

Other Methods to Study the Flow Past Single Rigid or Fluid ParticlesIn the present chapter we consider the steady flow past a single rigid or fluid particle at small, moderate and large Reynolds numbers. To this end we use analytical, numerical and asymptotic methods.
