Material analysed For this purpose, out of our series of 3,657 patients in whom artificial pneumothorax has been tried, we have studied certain points in 781, that is, in all patients in whom artificial pneumothorax has been attempted in the period from 1st January, 1940 to 31st December, 1943, and who have completed their treatment in the institution and have been discharged. Of these 781 case...

Casing collapse is one of the major problems in oil fields, imposing a lot of costs on oil companies. This problem occurs not only at drilling times in some formations but also after the completion and production can lead to many problems. Analysis of the behavior of casing collapse in terms of geo-mechanics and solid mechanics could significantly meet the needs of the oil industry of Iran. In ...

Allochthonous masses are common structures in Zagros fold-thrust belt. They are generally considered as collapse structures formed by the influence of gravity and in rock units with competency contrast. However, large allochthonous masses mapped in Dowgonbadan area in Dezful Embayment near the Mountain Front Fault (MFF) of Zagros show characteristics different from the belt common collapse stru...

In line with the current research on the ultimate strength assessment of ship hull girders, careful understanding of the collapse behaviour of unstiffened plate elements within the ship hull girders is an important and necessary task. In this paper, the collapse behaviour of unstiffened plates under longitudinal and transverse thrust is studied by elastoplastic large deflection FEM and the char...

Progressive collapse is defined as the spread of an initial failure from element to element, eventually resulting in the collapse of an entire structure or a disproportionately large part of it. The current progressive collapse analyses and design methods in guidelines and codes focus on the alternate load path method. This method is suitable especially in the case of blast-induced progressive ...

recently, two of the authors have introduced the collapse capacity spectrummethodology, which allows the assessment of the collapse capacity of highly inelastic p-deltasensitive regular frame structures without performing non-linear time-history analyses. the mainingredient of this method is the collapse capacity spectrum, which represents the seismic collapsecapacity of an inelastic non-deteri...

Intrapleural haemorrhage is a serious complication of artificial pneumothorax (A.P.), sometimes endangering life and often leading to obliterative pleurisy and loss of the A.P. It is the purpose of this paper to discuss its causes, incidence, pathology, treatment, and effect on the A.P., on the basis of a study of the records of 37 cases in which intrapleural haemorrhage of not less than one pi...

The branching ratios for the neutral and charged B decay channels to ηK and ηK are well above the Standard Model expectations. Moreover, the mixing-induced CP asymmetry in B → φKS is incompatible to that found in B → J/ψKS . We investigate whether a flavourspecific tree-level b → sss operator coming from R-parity violating supersymmetry can resolve both these discrepancies, without jeopardizing...
