(1) The cytotoxins are not specific. (2) The changes occurring after the injection of different cytotoxins are similar and do not vary in kind. (3) The changes do, however, vary in degree in the following order, the one having the most marked effect being placed first, etc.: (a) Hæmolymphotoxin, (b) Splenotoxin, (c) Lymphotoxin, (d) Endotheliotoxin, (e) Nephrotoxin, (f) Hepatotoxin. (4) Nephrotoxin causes the most specific change. (5) The hæmolymph glands play some important part in the production of eosinophiles. The hæmolytic action of hæmolymphotoxic serum is greater than that of other cytotoxic sera. (6) The histological changes which are observed in every case are secondary to the hæmolytic factor present in all cytotoxic sera.

In order to investigate the air injection method on the performance of an airlift. For this purpose an air lift system with a riser 2000 mm long and 80 mm in diameter, was designed and tested. Seven different air injection methods were used at a constant submergence. The experimental results showed a marked effect on the airlift performance when operated with different air injection methods. The arrangement of five nozzles gives the best performance, and the one nozzle is the worst. Although the injection angle has a little effect on the airlift performance, but view the general conclusions as a whole, the best lifting efficiency can be obtained when the angle of the nozzle placed along the tangential direction of pipe wall is equal to 10º at a given air flow rate QG =37m3/h.

Resumen: A partir de 1920 Le Corbusier comenzó a elaborar un cuerpo teórico sobre el diseño de objetos que iría difundiendo a través de sus escritos y conferencias. Libros como Vers une architecture, L´art décoratif d´aujourd´hui o Précisions sur un état présent de l'architecture et de l'urbanisme han constituído un rico legado de ideas e imágenes interrelacionadas que permiten analizar la propuesta del arquitecto desde el plano de la teoría. Sin embargo, el poder de sus postulados fue continuamente experimentado y corroborado por su obra en materia de mobiliario, hasta el punto de establecerse relaciones directas entre teoría y obra. Esta evolución conjunta proporciona una completa visión del concepto de mobiliario moderno desarrollado por Le Corbusier. Por tanto, esta investigación persigue, por un lado, sacar a la luz un verdadero cuerpo teórico de cuño 'corbuseriano' y específico del equipamiento moderno, haciendo especial mención a los postulados y dibujos originales del arquitecto y, por otro, comprobar la correspondencia real entre sus teorías y sus obras mediante el análisis de una escogida selección de obras del arquitecto pertenecientes al periodo de entreguerras, para, finalmente, ofrecer una caracterización 'corbuseriana' del mobiliario moderno. Abstract: From 1920 Le Corbusier began to develop a theoretical body on the objects design that went spreading through his writings and lectures. Books like Vers une architecture, L'art décoratif d'aujourd'hui or Précisions sur un état présent de l'architecture et de l'urbanisme have constituted a rich legacy of interlinked ideas and images to analyze the proposal of the architect from the level of theory. However, the power of its principles was continuously experienced and corroborated by his work in furniture, to the point of establishing direct relations between theory and work. This joint development provides a comprehensive overview of modern furniture concept developed by Le Corbusier. Therefore, this research aims on the one hand, to expose a 'Corbusian' and specific theoretical body of modern equipment, with special reference to the principles and original drawings by the architect; and, secondly, to check the real correspondence between his theories and works by analyzing a choice selection of works by the architect belonging to the interwar period, to finally offer a 'Corbusian' characterization of modern furniture.Palabras clave: Teoría; mobiliario; moderno; escritos.

Previous studies reported some associations between class A antibodies specific for benzo[a]pyrene (IgA-Bp), estradiol (IgA-Es) and progesterone (IgA-Pg) and breast cancer (BC) in women like as with lung cancer (LC) in men. It was suggested that IgA-Bp and IgA-Es may stimulate tumor initiation and promotion, whereas IgA-Pg may inhibit the in vivo human carcinogenesis.The purpose of this study was to identify the suggested associations of such immunological imbalance with BC and LC in postmenopausal women.The serum A-class antibodies specific to benzo[a]pyrene, estradiol and progesterone (IgA-Bp, IgA-Es, IgA- Pg) were studied in 335 healthy women, 824 breast cancer (BC) patients and 127 cases of lung cancer (LC) by means of non-competitive solid phase immunoassay. The following results were obtained: Increased ratio of IgA-Bp and IgA-Es amounts exceeding the IgA-Pg levels was associated with a higher risk of breast cancer (OR = 2.8 and 2.4 respectively, p < 0.0001), and higher risk of LC (OR = 2.9 and 2.8, respectively, p < 0.0001). Conversely, the OR values decreased to 0.3-0.4 for BC and LC if IgA-Pg levels were higher than IgA-Bp and IgA-Es levels (p < 0.0001). These findings confirm the hypothesis that IgA-Bp and IgA-Es are capable to stimulate, and IgA-Pg, to inhibit the BC and LC occurrence n postmenopausal women. The balance between IgA-Bp and IgA-Es, on the one hand, and IgA-Pg, on the other hand, is much more important than individual contents of these antibodies.In conclusion, the phenomenon of “immunological interference” is revealed, i.e., the mutual enhancement of IgA-Bp and IgA-Es effects, thus, probably, stimulating the initial and subsequent events of carcinogenesis initiation and promotion, with a weak anticancer effect of IgA-Pg, and by weakening the mutual procarcinogenic effects of IgA-Bp and IgA-Es by the marked effect of IgA-Pg.

It is argued that religions seem to insist, paradoxically, on both exclusivity and diversity to inspire passionate commitment on the one hand and to allow for genuine choice of religion on the other. The argument is developed with special reference to Islam, with hints of similar strands of thought in Judaism and Christianity. The paradoxicality of this position of religions is similar to Kierkegaard’s interpretation of faith, as exhibited byAbraham in his sacrifice. Interpreting religions in this way provides us with a better context for understanding the exclusivism/pluralism debate.

The issue of pathological and histological changes in the kidneys in children with various infections and other diseases cannot be considered sufficiently researched and worked out. Only in certain infections (scarlet fever) has much attention been paid to the study of the kidneys. Most of the works on the issue of interest to us date back to the time when, on the one hand, insufficient importance was attached to the early dissection of corpses and the freshness of the material, which, as is now known, is of particular importance for the histology of the kidney, on the other hand, such interpretation of the detected changes, which do not correspond to the views and concepts of modern nephropathology; Finally, those changes in views on some diseases that have occurred to date, for example, in the issue of disorders of digestion and nutrition in infants, dictate the need for a different approach to the study of renal changes in these diseases.

The discussion here is largely concerned with the purposes and structure of classifications of clinical concepts, variously called diseases, illnesses, disorders and syndromes, which are the main reasons why patients go to see doctors. Multiaspect (or multiaxial) classification has deservedly come to the fore in recent years, and seems likely to increase in importance for purposes of education, communication and research in the near future, but it is mentioned only briefly in the following discussion. The main focus of attention for the moment is the clinical descriptions of disorders; this is, of course, usually the first aspect in a multiaspect system, and the one around which the other aspects tend to be organised.
