ABSTRACT The primary aim of this paper is to study the Microstructual influence on fracture resistance in 7000 seriers aluminium alloys. Fracture toughness is an indication of the resistance of a material to physical separation by a process of unstable macrocrack propagation. The microstructural features such as coarse particles of intermetallic (IM) phases‚ dispersoids‚ inter- and intragranular precipitates‚ precipitate-free zones ‚ grain size and orientation are known to exert significant effects

be developed gradually‚ in other words‚ it is seen as a continuous process by collecting more information. Another way of developing cognitively is through a series of stages which involves some sort of revolution from one period to another in one’s lifetime. Jean Piaget‚ a cognitive developmentalist believed that humans go through a series of stages in life in order to reach their full cognitive ability. In this essay‚ we would briefly talk about Piaget’s Stage Theory and its criticisms. Piaget

compaction and oil palm (Elaeis guineensis) yield is unclear. Therefore‚ the objectives of this study were to determine the effects of mechanization on soil physical properties and the influence on oil palm yield. Approach: The palms were planted in Bernam series soil which is clay textured. Compaction treatments were imposed for 6 consecutive years. Comparisons were made between the effects of soil compaction caused by different trailer weights and monthly transportation frequency. Results: The results showed

What is VAP? Ventilator-associated and hospital-acquired pneumonia Ventilator-associated pneumonia (VAP) is pneumonia that develops 48 hours or longer after mechanical ventilation is given by means of an endotracheal tube or tracheostomy. Ventilator-associated pneumonia (VAP) results from the invasion of the lower respiratory tract and lung parenchyma by microorganisms. Intubation compromises the integrity of the oropharynx and trachea and allows oral and gastric secretions to enter the lower airways
