Lab Report Example | Topics and Well Written Essays - 1000 words

Lab Report Example (a) Give the gender, age and height of your subject using SI units. Calculate FVC and TLC for your subject using the above formulae, remembering to include units. Show your calculations (6 lines maximum; 10 marks). (b) FER expresses FEV1 as a fraction of FVC. Given this information, why do you think that FER is often used, in preference to the simple variables FEV1 or PEF, when comparing different individuals, or when determining whether an individual’s reading is normal? (5 lines maximum; 5 marks) ROW 10. Calculate using the fact that oxygen consumption (expressed under STPD conditions) is proportional to energy expenditure: 1 L of oxygen consumed is approximately equivalent to an energy expenditure of 20 KJ. (20 marks) [NOTE: In the above table, volume data has been expressed using the terms ATPS and STPD. ATPS means the gas volume measured under actual laboratory conditions of temperature, pressure and humidity; these may vary from day to day. STPD conditions on the other hand are standardised, and it is necessary to convert ATPS volumes to STPD before carrying out the calculation for energy expenditure in the above table.] (b) How do your values for resting oxygen consumption and energy expenditure compare with â€Å"normal values† given in a textbook or other reference source? Suggest possible causes for any differences found. Give your source(s) as â€Å"in-text references†, and include the full reference(s) in the list at the end of this report.(8 lines maximum; 10 marks) (c) State the type of exercise your subject undertook. How does your value for energy expenditure during exercise compare with â€Å"normal values†, for the same or a similar activity, as given in a textbook or other reference source?Suggest possible causes for any differences found. By how much might energy expenditure increase during maximum exercise? Give your source(s), as â€Å"in-text references†, and include the full full

How would you describe human personality - Essay Example ts, his own growth and development patterns, reactions and moods, his social encounters with the people around him– all these come together to help form his personality. This is how the book of Duane and Sydney Schultz (2005) view personality. The formation of one’s personality is dependent on many factors that may inter-relate or overlap. Personality traits are believed to be inherited. They may also be influenced by one’s environment. Personality traits may also be learned from experience or may be strongly molded by the parenting style one has been exposed to. Personality may also be affected by the changes we encounter in life. It is also controlled by conscious and unconscious processes. A person’s experiences leave imprints on his personality. For instance, well-adjusted, well-rounded and successful individuals often share a childhood marked by happy memories and nurturing relationships with family and friends.

These personal views on personality were influenced by my exposure to the Psychoanalytical theories of Freud, Jung and Erikson. I found it fascinating, albeit complicated.

The Psychoanalytic theory is premised on the belief that human nature is greatly affected by a person’s early childhood experiences and conflicts between impulses and prohibitions. Sigmund Freud’s views human behavior as determined by irrational forces, unconscious motivations and biological and instinctual drives evolving in the first six years of life. According to Freud, there are two levels of personality: the conscious corresponds to its ordinary everyday meaning; the unconscious is the invisible portion of personality below the surface. (Schultz
