Modernisation of a Breathing Simulator Hoist. Part 1

Published Online: 03 Jan 2019
Page range: 7 - 24

Abstract

Abstract

This article presents the process of modernisation of a car lift in order to adjust it to the function of a hoist for lifting the decompression chamber cover in a breathing simulator used in the Department of Underwater Work Technology of the Naval Academy in Gdynia.

Description of the Adsorption Equilibrium with Consideration to the Decreasing Availability of Space in the Course of Mobile Adsorption of a Single Gas on a Homogenous Surface of Solid

Published Online: 03 Jan 2019
Page range: 25 - 38

Abstract

Abstract

The subsequent stages of the process of formulation of the equation for gas adsorption on a homogenous surface of a solid adsorbent were presented based on the general expression for the canonical ensemble of the mobile single-component adsorption monolayer. The method of formulating the configuration integral of the proposed model was discussed in detail where the role both of the attraction and repulsion between adsorbed molecules was emphasised. The expression for the probability of finding a molecule in a specified point on a surface of an adsorbent was modified by determining its magnitude by the adsorbent concentration. The expression for the so-called effective surface of the adsorbent was obtained by adapting a two-dimensional analogue equation of state hard spheres – Van der Waals equation (2D-vdW) and Reis-Frisch-Lebowitz equation accordingly (2D-RFL). As a result, two new adsorption equations were formulated which differ in detail concerning the adsorbate-adsorbate repulsion. On each of these equations theoretical analysis was performed in terms of two-dimensional phase transformation. In both cases it was proved that the proposed solution allows for the presence of two-phase transformations of the first type which is the gas-liquid condensation and solidification liquid-solid. The verification of the given approach was supplemented by the description of the experimental data given in reference literature and by obtaining a very good correlation between the theory and experiment.

Diabetic Patients Who are Amateur Divers

Published Online: 03 Jan 2019
Page range: 39 - 44

Abstract

Abstract

Diabetes is an “epidemic of the 21st century” and it is estimated that in 2011 6.7% of Poland’s population suffered from diabetes, one quarter of which was unaware of the disease. Such a high prevalence of diabetes mellitus results in an increasing number of physicians being confronted with the problem of qualifying patient with diabetes to partake in amateur sports, including diving. This publication presents the most important information concerning risk assessment, admission of diabetic patients to amateur diving and some proposed protocols of management before and during sport practice.

Accidents Caused by the Difference in Air Pressure Inside the Diving Apparatus and the Water Surrounding the Diver

Published Online: 03 Jan 2019
Page range: 45 - 54

Abstract

Abstract

This paper describes 4 unfortunate accidents caused by the difference in pressure inside and outside the diver’s suit. The issues relate to diver crushing, caisson disease, too fast an ascent to the surface and hypoxia as a result of exhaustion of oxygen in the diving apparatus are explained. The mechanism of the diving injuries was analysed and methods of prevention of such incidents were suggested.

Risk Management in Kitesurfing as a Basic Condition of Effective Learning and Safe Swimming

Published Online: 03 Jan 2019
Page range: 55 - 67

Abstract

Abstract

This article discusses issues related to safety during kitesurfing (swimming on a board with a kite). The considerations are based on risk management procedures. These procedures can be described interchangeably as managing your own safety. Risk management allows you to minimize threats without sacrificing your planned sport goals. The authors first describe the procedures related to the identification of threats occurring in this discipline. Teaching and practicing kitesurfing involves overcoming a large number of threats. These threats can have both external and internal character. The next stage is risk analysis, understood as the product of negative events and the probability of their occurrence. Afterwards, we discuss the ways of dealing with the threat in the event of its occurrence. The last stage is the risk control (tracking) - whether new threats have emerged, or the level of risk has remained unchanged. The described methodical impacts can be labelled as education for safety.
