Oxygen is carried in red blood cells by the pigment haemoglobin‚ a globular protein consisting of four polypeptide chains. Both of these components of blood are structured specifically to carry out their functions of oxygen transport‚ hence ensuring efficient respiration. Erythrocytes‚ or red blood cells‚ possess a unique structure that enables them to play their role in oxygen transport. They are small‚ at 7μm in diameter‚ compared to that of average animal cells (approximately 20μm). This allows them

The Ball Mill is a mill‚ one of the main working parts. In addition withstand grinding ball body of work‚ the static load‚ but also by the impact of grinding media‚ and the ball is rotating‚ so the ball to generate the alternating stress. Therefore‚ it must have sufficient strength and stiffness. This requires the manufacture of metal ball strength of the material must be high‚ plastic is better‚ with good mechanical properties and process performance in order to ensure the safe operation of ball

Efficient and effective policies to solving climate change Global warming is an issue that has recently been pushed to the forefront of political leaders debates and policy making. With temperatures at the end of the century that ‘might be up by anything from 1.1C to 6.4C’(Economist 2009) and the fact that ‘current average global temperatures are only 5C warmer than the last ice age’ (Economist 2009) there is some serious concern about the welfare of humans over the next century. However the predicament

The role of financial intermediation in the economic growth process was recognised as far back as the 17th century when Walter Bagehot‚ in his classic Lombard Street‚ argued that it was England’s efficient capital markets that made the industrial revolution possible. Centuries later‚ modern day economists hold largely the same view that access to investment capital‚ through well functioning financial markets‚ is crucial for growth and development‚ particularly in capital-scarce developing countries

How are organisms adapted for efficient gas exchange? [25 marks] Many organisms have different features which enable them to survive and carry out gas exchange effectively. Single-celled organisms‚ such as bacteria and protozoa‚ are in constant contact with their external environment. For them‚ gas exchange occurs by diffusion across their membranes. Even in simple multicellular organisms‚ such as green algae‚ their cells may be close to the environment‚ and gas exchange can occur easily. In

Efficient Method for Re-encryption in Unreliable Clouds Using R3 Algorithm Abstract— Aim of the project is to re-encrypt the data and revoke the access rights from the users. In this paper‚ we propose an efficient data retrieval scheme using attribute-based encryption. The proposed scheme is best suited for cloud storage systems with substantial amount of data. It provides rich expressiveness as regards access control and fast searches with simple comparisons of

1. Problems Identified 1.1 Structural Strategy 1. No proper project structure - this made the execution and management of the project very ineffective. 2. Project over budget – The project estimated cost overrun of atleast 20% 3. Poor leadership/no leadership commitment - the customer requested the Divisional GM and his team to present the status of the project. However the DGM instructed Reichart to go with any other 3 or 4 functional managers 4. No Balanced Scorecard with critical success factors
