On the Brauer Indecomposability of Scott Modules

Let k be an algebraically closed field of prime characteristic p, and let P be a p-subgroup of a finite group G. We give sufficient conditions for the kG-Scott module Sc(G,P) with vertex P to remain indecomposable under the Brauer construction with respect to any subgroup of P. This generalizes similar results for the case where P is abelian. The background motivation for this note is the fact that the Brauer indecomposability of a p-permutation bimodule is a key step towards showing that the module under consideration induces a stable equivalence of Morita type, which then may possibly be lifted to a derived equivalence

Some new aspects of benzyne and radical mediated cyclisations

KNH2/NH3 cyclisations of some alkoxy substituted arylhalides proceed in poor yields. This shortcoming may be overcome by the use of LDA/THF to effect the ring closure which may occur through benzyne or radical intermediates. Besides ortho halogenated dihydroanils and amides, the cyclisation of the benzylamine Schiff bases also provides a convenient route to isoquinoline alkaloids

Effects of high intensity physical training in patients with Chronic Obstructive Pulmonary disease in a Pulmonary Rehabilitation Program / Efeitos do treino físico de alta intensidade em doentes com doença pulmonar obstrutiva crónica num Programa de Reabilitação Pulmonar

Objective: To evaluate the effect of high intensity physical training on a supervised Pulmonary Rehabilitation Program (PRP) in patients with Chronic Obstructive Pulmonary Disease (COPD). Methods: Interventional study with 30 patients with COPD, randomly divided into 2 groups: Control Group (CG) submitted to physical training of a traditional PRP and Experimental Group (EG) with bodybuilders with duration of 30 sessions in days alternates. All submitted to pre and post-intervention evaluation with the following variables: (I) pulse oximetry (SpO2); (II) 6 'walk test (6MWT); (III) Saint George's Quality of Life Questionnaire (SGRQ); (IV) DPOC assessment test (CAT); (V) cardiopulmonary exercise test; and (VI) 1 maximal repetition test (MRI). Results: Pre and post-intervention values were compared and the GE group presented a significant difference in the following parameters: increase 30.53 meters in the distance covered (p 0.021) improvement in all scores: CAT score for 12 points (p < 0.001), Score Saint George from 27 to 19 points (p 0.005), and in the improvement of the maximum physical capacity with increase 14 to 18 of (VO2 (%) (p 0.007) and 0,87 to 1,12 VO2 (L/min) (p 0.01) Conclusions: There was a significant improvement in exercise capacity and quality of life of the GE group, suggesting that high intensity physical training is the most efficient alternative in the treatment of patients with moderate COPD will be severe

Organic synthesis via photoinduced hydrogen and electron transfer reactions

Synthetic utility of photoinduced intramolecular hydrogen transfer reactions of ketones, amides, imines, nitrites and nitro compounds is highlighted by illustrative examples. Role of light-initiated electron transfer from amines, mercaptans, aryl groups and from lithiated ketones, amides and imines in reactions of synthetic interest is discussed

New routes to condensed polynuclear compounds: Part XVIII-Cyclisations through naphthynes and pyridynes

It has been shown that the KNH2/NH3 cyclisation of ortho/meta halogenated Schiff bases, or the corresponding dihydro compounds, succeeds when 1,2-naphthynes and 2,3-pyridynes are involved as intermediates. Using this procedure 3-aza-benzo[j]phenanthridine, 9-azaphenanthridine and 2,11-diazachrysene have been synthesized
