Jeffrey Sachs is an economist so you may wonder whether this book contains information relevant for soil scientists. Well, it does! And let me tell you about this book, the author and why this book should be read by soil scientists fascinated by big questions, global issues and readable books. The book title refers John Maynard Keynes' from 1930 " Economic possibilities for our grandchildren "....

J effrey sachs is an economist, not an evangelist. But give the man 10 minutes behind a microphone, and a scholarly symposium starts to feel like a revival meeting. “Ladies and gentlemen,” he tells a hushed hall after describing how AIDS sufferers die in Malawi for want of $1-a-day drugs, “this plague is exploding. Its consequences will make the world quake. Rich countries could stop the devast...

Deviations from the Friedmann-Robertson-Walker (FRW) cosmological model in the form of density inhomogeneities induce observational effects on the light propagating through these fluctuations. Using a rigorously parametrized metricwhose pseudo-Newtonian potential is related to (possibly nonlinear) density inhomogeneities through a relativistic Green function, the behavior of radiation propagati...

BACKGROUND The effect of osteoallograft repair of a Hill-Sachs lesion and the effect of allograft fit on glenohumeral translations in response to applied force are poorly understood. PURPOSE To compare the impact of a 25% Hill-Sachs lesion, a perfect osteoallograft repair (PAR) of a 25% Hill-Sachs lesion, and an "imperfect" osteoallograft repair (IAR) of a 25% Hill-Sachs lesion on glenohumera...

BACKGROUND Numerous surgical options for the management of engaging Hill-Sachs lesions exist, of which remplissage has emerged as one of the most popular arthroscopic techniques. Remplissage is not without disadvantages, however, and has been demonstrated to potentially result in a loss of external rotation (ER) due to nonanatomic tethering of the infraspinatus tendon and a potential decrease i...

BACKGROUND Introduction: GM2 is a type of ganglioside. It is associated with GM2 gangliosidoses such as Tay-Sachs disease.

The well-known Sachs and Taylor bounds provide easy inner and outer estimates for the effective yield set of a polycrystal. It is natural to ask whether they can be improved. We examine this question for two model problems, involving 3D gradients and divergence-free vector fields. For 3D gradients the Taylor bound is far from optimal: we derive an improved estimate which scales differently when...
