Once the electricity is generated‚ the equipped shoe can use the electrical power for rehabilitation purpose such as thermal and cold therapy. Two effective‚ automatically controlled heating and cooling instruments embedded in the shoe ’s sole maintain proper temperature and humidity within the normal or user selected range. In addition an alternative cooling system which is less expensive but effective has been proposed. Another

CHAPTER I INTRODUCTION Background of the Study In the Philippines‚ forests and woodlands cover about 7‚168‚400 hectares (http://forestry.denr.gov.ph). These forests have unique environmental and biodiversity values‚ and make available a wide range of products for subsistence use. The most predominant use of wood is in the form of firewood and charcoal by the majority of Filipinos in both rural and urban areas. Firewood is preferred in rural areas simply because it is obtainable free of charge

Non-reducing sugar Test Observation Sucrose Colourless solution turned from colourless to blue after Benedict’s solution is added. While heating‚ blue solution turned to yellow then green and final colour was reddish orange. Sucrose solution before anything is added. Sucrose solution after heating for 1 minute.

Pre Lab 1a. Hydrated compound: ionic compound which contain water molecules inside their crystal lattice. The water is not chemically bonded to the crystal in any way and can be extracted by heating the compound. 1b. Anhydrous compound: a compound without water. 2a. The dot means that there are water molecules present in the crystal lattice in a specific ratio. 2b. For every mole of copper sulfate‚ there are five moles of water. 2c. The molar mass of copper (II) sulfate is 159.61 grams/mol

Fractional Distillation of an Ethanol- water Mixture Abstract The purpose of this experiment is to understand the process of distilling a solution. Thesolution of 50/50 ethanol-water was used in the experiment. Using fractional distillationapparatus ethanol-water mixture was separated. The fractional use of copper sponge wasused in distillation process which created the heat exchange area between the vapor of ethanol and liquid water. The fractional distillation process yield 9.5 ml of ethanol

It also has electrical cord‚ temperature control dial and a sole plate. · The design should allow the iron to be set down‚ usually standing on its end‚ without the hot soleplate touching anything that could be damaged. · Thermostat : When we switch on the electric iron current flows throught the heating coil. The heat in the heating coil causes expansion in the thermostat which gradually disconnects the supply. · Heating Coil : a coil made of

possible to hedge diesel fuel directly. Heating oil and diesel fuel‚ however‚ are highly correlated in market prices (.99 correlation). Thus‚ J & L can use heating oil to hedge. But what if there is a black swan event and the correlation between heating oil and diesel changes (The idea is similar to the problem that non-profit organizations had during the 2008 recession with the interest rates swaps). This is an extra risk for J & L to hedge using the heating oil futures. Risk management instruments
