TECHNOLOGIES BEHIND LIQUID CRYSTAL DISPLAY (LCD) Brief Overview- A thin‚ flat electronic visual display that uses the light modulating properties of liquid crystals is known as a liquid crystal display. Direct light is not emitted by LCDs. Displaced cathode ray tube (CRT) displays of LCDs are used in most applications. Two sheets of polarizing material‚ are used in LCD displays‚ with a liquid crystal solution between them. The crystals align as a result of an electric current‚ so that light

How Sugar Impacted the World In the dispute of sugar‚ one debatable issue has been whether sugar is beneficial or harmful to the world. People who believe sugar is harmful argue that it is one cause of diabetes. On the other hand‚ those who believe that sugar is beneficial claim that sugar taste good and it is in every food so it cannot be avoided. Sugar has not had a positive impact on the world because it causes obesity‚ diabetes‚ and sugar also helped promote slavery in the past. What is your

Alum Crystals from Solutions in Two Different Thermal Conditions Burce P.J.‚ Cachuela J.A.A.‚ Capistrano M.M. I. Objectives The experiment aims to describe crystals and its aggregates by creating crystals of Alum (AlK (SO4)2 ∙12H2O)‚ commonly known as Tawas‚ from solution. Two setups will be created; crystals from each setup will be allowed to form at two different thermal conditions. With this‚ the experiment also aims to describe how temperature affects the formation of crystals.

When reading “The Toxic Truth about Sugar” the reader may believe it is just another essay telling Americans they are all obese and will die at an early age if they don’t start eating healthier. However‚ it brought up some different points the reader may not be aware of. The authors brought up some valid points to support their argument. The title was creative because many people do not believe sugar is toxic to their body. In the world today people love sugar and it is all around. Many foods people

6.2 The influence of an inhomogeneous spatial distribution of sugar on a biscuit’s appearance A biscuit’s appearance was influenced by the amount and spatial distribution of sugar. Table 6 shows that more participants thought biscuits A and B should be darker than that they though biscuits C and D should be darker. Qualitative data shown in table 10 partly supports this‚ as biscuits D were observed to be the darkest. Table 7 partly supports this as well. For the question “How is the appearance of

The production of reducing sugars by acid of carbohydrate cereals powder‚ jams (total sugar content) and jams (reducing sugar content) were performed in order to study reducing sugar production. The study involved hydrolysis carbohydrate cereals powder and jams by immersing in boiling water at environmental temperature. Acid hydrolysis was carried out through reflux boiling for 20 minutes with 10ml 0f 1.5M concentrations of diluted sulphuric acid. Reducing sugars concentrations were determined

First‚ we must establish whether sugar over-consumption is damaging to one’s health. In the Vice article‚ the writer made an eyebrow-raising statement when she said‚ "sugar is devoid of any real nutrition‚ messes with your metabolism‚ and rots your teeth...How bad could it really be?" This was interesting to me because I always thought sugar was an extremely important source of energy and that our body had a built function to regulate the amount of sugar we consume.

Data Analysis The question for this experiment was‚ “Does sugar effect recalling memories?” The hypothesis was‚ “If sugar causes drowsiness‚ then it will slow the memory process also.” For this experiment‚ the independent variable was the participants‚ and the dependent variable was the accuracy percentage. The control variables were the amount of numbers required to memorize‚ the time before recalling the numbers‚ and the type and brand of donuts. The participants who did not eat the donuts were

Osmosis coursework Aim: To investigate the effect of different concentration of a sugar solution on the amount of osmotic activity between the solution and pear pieces of a given size. Define osmosis: Osmosis is a net movement of water/ solution molecules from a region of high concentrated area to a region of lower concentrated area through a semi-permeable membrane which lets smaller molecules such as water through but does not allot bigger molecules like glucose to pass through. The molecules

THE PROCESS OF FERMENTATION THROUGH DIFFERENT KINDS OF SUGARS In order to produce ethyl alcohol fermentation‚ we had to determine what sugars used‚ such as glucose (a single sugar) sucrose (table sugar) and lactose (milk sugar) will react with yeast to produce ethyl alcohol fermentation. My hypothesis is that the sugar lactose would produce the highest amount of bubbles and ferment. INTRODUCTION: The significance of fermentation is a lengthy process that has been practiced by humankind
