Recent Progress in Solar Physics
A number of significant recent advances in solar physics are reviewed. New kinds of observations made during the present sunspot cycle, which began in 1954, have emphasized still further the apparent complexity of solar phenomena and the need of nonequilibrium theoretical treatments. Among the new developments di cussed are solar cosmic rays and highenergy particles, flares and prominences, cor...
متن کاملKaon Physics: Recent Experimental Progress
The last three years have been marked by very rapid progress in experimental studies of kaon decays. This review is an attempt to summarize those results that offer direct comparison for the predictions of chiral perturbation theory (ChPT), including in particular the determination of the I = 0, 2 ππ scattering lengths from K → 3π and Ke4 data, recent results on a selection of rare and radiativ...
متن کاملRecent Progress in Allergen Immunotherapy
The efficacy of allergen immunotherapy for the treatment of allergic rhinoconjunctivitis with or without seasonal bronchial asthma and anaphylaxis caused by the sting of the hymenoptera class of insects has been clearly demonstrated in numerous well-designed, placebo-controlled trials. Immunotherapy whether by subcutaneous injection of allergen extract or by oral/sublingual routes modifies peri...
متن کاملRecent Progress in Heavy Quark Physics
Some of the recent progress in heavy quark physics is reviewed. Special attention is paid to inclusive methods for determining V ub and factorization in nonleptonic ¯ B decays. Theoretical predictions for ¯ tt production near threshold are also discussed. Since QCD cannot be solved exactly every theoretical prediction of the properties of hadrons containing one or more heavy quarks involves app...
متن کاملRecent Progress in Zeolite/Zeotype Membranes
This is a comprehensive review of the recent progresses made in the field of zeolite membranes. It describes zeolitic materials and methods of membrane fabrication, followed by a summary of applications for gas separation, pervaporation and separation of liquid mixtures. Special attention is called to polymer mixed matrix membranes (MMMs) and membranes based on metal organic frame works (MOFs)....
