TARGET OUTPUT At the end of this unit, You will be asked to: ‘write a summary on one aspect of note-taking’

Part A: DISCUSSION 1. Consider the following questions alone: a) What reasons do people have for listening to others? ___________________________________________ ___________________________________________ ___________________________________________ b) Why do they listen at university? ____________________________________ ____________________________________ c) What is the difference between academic and non-academic listening? _________________________________________________ _________________________________________________

ACADEMIC SKILL TIP: CHOOSING A NOTE-TAKING METHOD In order to get the most from your lessons, you must develop a note-taking method that works for you. You can do this by looking at different ways of note-taking and deciding which one is suitable for your learning style. Work on a method that will gradually help you to structure and organize your notes to make your note-taking speed and comprehension better. · Start each lecture on a new page; date and number each page. · Write on one side of the paper only. You can set them out side-by-side for easier reviewing when studying for an exam. · Leave blank spaces. This allows you to add comments or note questions later. · Make your notes as brief as possible. · Develop a system of abbreviations and symbols you can use wherever possible. · Note all unfamiliar vocabulary or concepts you don't understand. This reminds you to look them up later.

Water treatment or Water Purification Arsenic is a colorless, odorless, tasteless element that can lead to skin discoloration, sickness, cancer and death. Arsenic contamination in drinking water is a global problem, and while there are ways to remove arsenic, they require extensive hardware and high-pressure pumps that run on electricity, Our approach is simple and requires no electricity. While the magnetic nanoparticles used in the publication are expensive, we are working on new approaches to their production and reusage.

Optical Study (UV-vis) Results Hammamet- 2013 Band gap energy of nanomaterials may change with the size and shape of the particles or defects on the particles and also strongly dependent upon the synthesis methods used.

Magnetization Measurements (VSM) Hammamet- 2013 Ms= 3x10-3 emu/g M-H curve has an s-shaped curve with a coercivity of 60 Oe which indicates that the ZnO nanoplatelets exhibit a typical ferromagnetic behavior at room temperature.

FC-ZFC Magnetization Ferromagnetic (FM) behavior at all measuring temperatures. FM behavior is attributed to uncontrolled formation of lattice defects generating carriers that mediate ferromagnetic behavior as observed in earlier studies.
