M. Velas FUNCTIONS OF LEISURE Relation to Increased Production and Consumption The function of leisure is largely determined by the kind and amount of free time and by the ideas of the age. When spare time consists of short breaks between long periods of sustained labor‚ its function is thought of as recreation – relaxing the worker so that he can work more efficiency after the break. When the goals are efficiency of work‚ increased production‚ more power and more wealth‚ the function of leisure

Investigating Aspirin Aims Synthesize my own aspirin Analyse the purity of my aspirin samples (aspirin and recrystallized aspirin) compared to commercial aspirin by use of analysing melting points‚ TLC plates and colorimetry tests Investigate how pH effects the rate of hydrolysis of aspirin Background theory Making my own sample of Salicylic acid (to then be converted into Aspirin) Salicylic acid (2-Hydroxybenzoic acid) can be made by hydrolysing methyl 2-hydroxybenzoate.

Earliest Methods used to solve Quadratic Equation 1. Babylonian mathematics (also known as Assyro-Babylonian mathematics) was any mathematics developed or practiced by the people of Mesopotamia‚ from the days of the early Sumerians to the fall of Babylon in 539 BC. Babylonian mathematical texts are plentiful and well edited.[7] In respect of time they fall in two distinct groups: one from the Old Babylonian period (1830-1531 BC)‚ the other mainly Seleucid from the last three or four centuries BC

AIMS The aim of this experiment was to investigate the effect of temperature rise on the rate of transpiration of a plant (hibiscus) by measuring the plant’s water uptake in a period of time. HYPOTHESIS Transpiration is the process by which plants loses water to the atmosphere from their leaves. Water in the plant is lost to the atmosphere by evaporation. Evaporation of water can occur at any temperature. In the presence of sunlight‚ water in the plants evaporates into the intercellular air

Objectives 1. To recognize the macroscopic properties of five chemical systems at equilibrium 2. To observe shifts in equilibrium concentrations as stresses are applied to the systems. 3. To observe a shift in equilibrium concentrations associated with changes in temperature. 4. To explain the observations obtained by applying Le Chatelier’s principle.

Introduction Commissioned by the Deltion College from the third class International Business Studies I have written this report. The report you’ll see in front of you is the work of 10 weeks research. For this unit I’ve been asked to plan the set-up of a small business in my local area. Starting a business involves planning‚ making key financial decisions and completing a series of legal activities.

The investigation stage requires thorough examination in order to learn the exact natures of our challenges. Effective and comfortable solutions happen when we develop a stable plan and implement it. This requires brainstorming‚ visiting various sources‚ and performing individual research. Results need to be evaluated and compared in order to determine whether the plan is realistic and most suitable as a method. The sources will vary depending on each situation but are not limited when solving problems

Natalie Drossoyianni I.B 1 Psychology HL Discuss the use of technology in investigating cognitive processes. Technology has been very useful for the past few years in investigating cognitive process. With the use of neuro-imaging techniques‚ researchers can examine brain structure and function‚ and thus understand better the relationship between cognition and physiology. The basic neuro-imaging techniques are the PET‚ the MRI‚ and THE fMRI scan. The PET or else the positron emission tomography

Investigating Ratios of Areas and Volumes In this portfolio‚ I will be investigating the ratios of the areas and volumes formed from a curve in the form y = xn between two arbitrary parameters x = a and x = b‚ such that a < b. This will be done by using integration to find the area under the curve or volume of revolution about an axis. The two areas that will be compared will be labeled ‘A’ and ‘B’ (see figure A). In order to prove or disprove my conjectures‚ several different values for n will
