Human is in a contact with water from birth until the last day of its life even though people do not realize it. People take water for granted in the life and do not take attention of it while we do not really miss it. Indeed‚ water is absolutely necessary for all life forms on the Earth. There are two main kinds of water in Trenčín area: surface and ground water. There are several legislations and laws which water must contain. It is necessary to drink water treatments because of non- source pollution

Mendeleev set out to organize the 63 known elements according to their properties. Mendeleev wrote the name‚ mass‚ and chemical properties of each element on a separate card and arranged the cards by various properties‚ looking for trends and patterns. When he arranged the elements by increasing atomic mass‚ Mendeleev noticed that similar chemical properties repeated at regular intervals. This type of repeated pattern is called “periodic‚” which is where the periodic table gets its name. The first question

Purpose: The purpose of this lab was to determine the freezing point of pure water‚ the experimental van’t Hoff factor for a substance and the molar mass of an unknown solution. Reagents: 25mL deionized Water ¼ to ½ inches of rock salt 25mL Sodium Nitrate (NaNO3 ) 25mL unknown solution – handle unknown solution carefully Procedure: For part 1‚ the freezing point of deionized water was determined. An ice bath was prepared by filling a 600mL beaker ¾ full of ice and covered with ¼ to

A Novel efficient Block Based Segmentation Algorithm for Compound Image Compression ABSTRACT Compound image comprises of the combination of text‚ graphics and natural images. Compression and transmission of these compound images are the essential processes in the real time applications where segmentation plays a crucial role. Compound image transmission for real-time applications require that the compression technique should not only attains high compression ratio‚ moreover has low complexity

Review Problems#3 Question-1 Mark Goldsmith ’s broker has shown him two bonds. Each has a maturity of 5 years‚ a par value of $1‚000‚ and a yield to maturity of 12%. Bond A has a coupon interest rate of 6% paid annually. Bond B has a coupon interest rate of 14% paid annually. a. Calculate the selling price for each of the bonds. ANSWER: b. Mark has $20‚000 to invest. Judging on the basis of the price of the bonds‚ how many of either one could Mark purchase if he were to choose it over

Section 1 As a member of Group 2‚ we were investigating why the liquids Ethanol‚ Propanol‚ Water‚ Pentane and Acetone evaporate at different rates. Methanol and Butanol were not liquids investigated by our group‚ but collectively as a class we were able to record averages of rates of evaporation.

Lecture Notes: Basic Electricity Fall 2011 This course module introduces the basic physical models by which we explain the flow of electricity. The Bohr model of an atom – a nucleus surrounded by shells of electrons traveling in discrete orbits – is presented. Electrical current is described as a flow of electrons. Ohm’s law – the relationship between voltage‚ current and electrical resistance – is introduced. Learning Objectives Understanding the basic principles of electricity is a foundational
