THE POSITIVE PRESSURE METHOD OF ARTIFICIAL RESPIRATION

[The Holger Nielsen method of artificial respiration].

A New Method of Artificial Respiration

The two main recognized methods of artificial respiration, namely, Schafer's and Silvester's, depend for their efficacy on the elastic recoil of the chest wall and diaphragm, which can happen only when the integrity and tonicity of the muscles of the respiration are maintained. Schafer's (1907-8) method consists in Maying the subject prone, and pressing gradually for three seconds with both han...

buckling of viscoelastic composite plates using the finite strip method

در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....

Some Modifications in Method of Treating Tetanus Neonatorum with Intermittent Positive-pressure Respiration.

In a previous paper we showed that the treatment of severe tetanus neonatorum by means of total paralysis and intermittent positive-pressure respiration (I.P.P.R.) represents a real therapeutic advance (Wright, Sykes, Jackson, Mann and Adams, 1961), and this has since been confirmed in Cape Town by Smythe (1963). Mortality rates of over 80% on conservative treatment have been reduced by this te...

Prediction of the Liquid Vapor Pressure Using the Artificial Neural Network-Group Contribution Method

In this paper, vapor pressure for pure compounds is estimated using the Artificial Neural Networks and a simple Group Contribution Method (ANN–GCM). For model comprehensiveness, materials were chosen from various families. Most of materials are from 12 families. Vapor pressure data of 100 compounds is used to train, validate and test the ANN-GCM model. Va...
