I will describe a typical case?" ex uno disce omnes." A European soldier comes to hospital complaining of debility, lassitude, malaise, cough, pain in the chest and in one or perhaps both shoulders. The respiration may be slightly accelerated, but not necessarily so; the pulse and temperature are normal. The Medical Officer makes a stethoscopic examination, very naturally expecting to find some...

The scattering of γπ → ππ is studied using the axial anomaly, elastic unitarity, analyticity and crossing symmetry. Using the technique to derive the Roy’s equation, an integral equation for the P-wave amplitude is obtained in terms of the strong P-wave pion pion phase shifts. Its solution is obtained numerically by an iteration procedure using the starting point as the solution of the integral...

Chiral perturbation theory supplemented by the Omnes function is employed to study the strength of the isoscalar central nuclear interaction, GS , in the chiral limit vs the physical case. A very large modification is seen , i.e. ηs = GS chiral/GS physical = 1.37 ± 0.10. This large effect is seen to arise dominantly at low energy from the extra contributions made by massless pions at energies n...

The concept of “national competitiveness” is mostly confused with that of development of countries, often reduced to their economic growth only, and with that of competitiveness of enterprises of the latter, too. Its measurement by some composite indexes, particularly by the single “Global Competitiveness Index” in the annual reports of the World Economic Forum is not only biased by the neo-lib...

تعتبر معاهدات الصلح من اهم انواع المواثيق الدولية التي تربط مقدرات الدول لاسيما المنهزمة منها على المدى البعيد، اذ تترتب عليها تعهدات اقتصادية وسياسية تلزمها بالتنفيذ حتى وان كانت مجحفة بحقها وغير منصفة، مما يؤدي في بعض الاحيان الى انهيار انظمتها السياسية واستبدالها بأخرى او اقتصادها نتيجة اثقاله بالديون الدولية، لهذا خلقت المختلفة قروحاً عدة، الرغم مكافحة مؤيدي المثل العليا الذين يدعون التهدئة ...

O escopo desse artigo visa salientar o discurso poético presente no “Slam das Minas do Rio de Janeiro” como ato re(Existência), trazendo à luz surgimento coletivo e a sua contribuição para construção uma sociedade mais inclusiva. Abordaremos corpo relevância os ambientes outrora lidos sacralizados, vez que slam, através táticas, consegue ocupar alguns desses territórios, evidenciando, assim, ou...
