Two very clever burglars were arrested in the early hours of the morning. The incident occured in the alley behind Pearson's Electronics Shop, in the South Street. Joe Lee, 30, and Peeter Brown, 23, had just finished loading a van with thousands of pounds worth of electronics equipment when they were surrounded by policeman. The two men had been breaking into electronics shop in the Forest city area for several months. They had continuosly eluded police by cleverly disarming alarms and changing getaway vehicles. Captain Green of the police department said that they had been on burglars trail for some time now and that they had only been waiting for the right moment to catch them in the act.

Electrical engineering What is electrical engineering? Electrical engineering is a field of engineering that generally deals with the study and application of electricity, electronics, and electromagnetism Info about electrical engineering This field first became an identifiable occupation in the later half of the 19th century after commercialization of the electric telegraph, the telephone, and electric power distribution and use Subsequently, broadcasting and recording media made electronics part of daily life. The invention of the transistor, and later the integrated circuit, brought down the cost of electronics to the point they can be used in almost any household object. Famous people with big impact are Nikola Tesla, Alexander Graham Bell, john Logie Baird and many more How to become an electrical engineer Electrical engineers typically hold a degree in electrical engineering or electronic engineering.

The importance of the internet in our lives Nowadays there has been huge development in electronics and people are using computers more than ever before. Programmers has created a virtual environment where people can chat with each other, read newspaper and do almost everything. To start with, I do not know anyone who does not have computer or access to internet. Internet has became very popular because for low price you can send letters, chat with your friends live in msn and even have video conversations with them. Furthermore, the internet is like a world biggest library. There is a lot of information about everything. For example, if you want to know the name of Estonian president you will find it in the internet,in few minutes. In the other hand, sitting too many hours in computer is not good for your eyes. For example,more and more people are wearing classes because of watchin...

Dear Kate, I'm writing you to thank you for your letter where you asked whether or not I like travelling and which places I want to see next. Firstly, I simply adore travelling and take every opportunity I can to visit different countries. My last trip took me to the Finland where I met a lot of interesting people. Secondly, there are some countries I am dreaming to visit some day in the future. I would really like to travel to Japan. I would love to visit a country which has very rich traditions and culture. There are very proud and generous people. I would like to see some festivals there and also visit some old castles and temples.Also Japan is known for its robots and technical gadgets. And of course I like to see citylights in the night and go shopping to big centres. Shibuya 109 is a mutli-storey shopping centre just for teenage girs. And Akihabara in Tokyo is know solely for its electronics and games. Finally, the only negati...

Greenpeace general facts. Greenpeace is a non-governmental organization which was found in 1971 by Kumi Naidoo who is an executive director and Lalita Ramdas who is a chairman. Greenpeace has about 2.86 million members in 41 different countrys and its main office is located in Amsterdam. Origin. The founders of Greenpeace believed a few individuals could make a difference which motivated them to stop USA's underground nuclear testing and that was the first time they did something good for environment and they wanted to keep doing that. Objectives 1 Greenpeace is perhaps best known for its campaigns to protect whales and other large aquatic animals from hunters and trappers. Greenpeace programs target multiple areas of ocean defense, centering primarily on pollution and unfair or abusive fishing practices. 2 Many electronics and other products contain toxic chemicals and heavy metals that are difficult to dispose of and impossible to r...
Subject: Proposal concerning the new shopping center Date: November 11, 2013 Introduction The purpose of this proposal is to give insight into the residents' committee's opinions regarding the new shopping center. Reasons it should be built The resident's committee has concluded that the new shopping center would be useful for people in our town as it would give them more choice in where to shop. Also, since there are no any decent sized shopping centers nor malls nearby, the new one would make people's lives easier since they would not have to drive as far out of the town as they are used to at the moment. Stores the shopping center should contain The shopping center should most importantly contain a big grocery store where people could buy their everyday food and drinks. Clothing stores would also be very useful as there are not many around this town. Lastly, we would propose electronics and free time stores and sporting goods store...
Report A task was given to write a report which conveys the results of a survey about shopping habits of people of different ages and gender. The results of the survey were mostly the same, although there are some differences in answers. How much does one shop? About 1/3 of the 9 people surveyed said that they go shopping once a week. Others said that they shopped at least two times a week and it takes about 30 minutes for men and a hour for women to buy groceries and at least an hour if it's a shopping spree. How much do you spend on your hobbies? All men (4 out of 9 people surveyed) said that the most enjoyable products to shop for are electronics while all the women agreed that clothing and acessories are the most fun things to buy. Men also spend less than women, about 50 euros and about 80 euros a week respectively. The experience itself Women said that they enjoy shopping with friends ...

Good morning ladies and gentlemen! Im going to talk about Business in Estonia. I`ve divided my talk into three parts. First Im going to give a short overview of the Estonian business. Second Im going to talk about studying business in Estonia and third Im going to talk about business in industrial sector. FIRST: Estonia is a relatively small country in the northern part of Europe. Estonia is strategically placed in the business corridor, between the Scandinavian countries (EU) and other eastern European countries, including Russia. Estonia has suffered from economic Chrisis as many ohter European countries and compared to ohter bigger countries like Spain and Greece, Estonia has managed to recover from the Chrisis quite well. The number of unemployed people has reduced, still many private companies have struggles due to the fact that the income of consumers has been low and the ability to consume products provided by the companies has...

Estonian teen How do you spend your free time? I'm pretty busy. Every day, I have music school, choir, or basketball training. I have been going to music school for seven years, and I'm going to graduate this spring. I have been going to basketball training for two years. I unfortunately can't go there very often because of music studies. When I'm home, I usually spend my free time on the computer or playing the guitar. What do you like / dislike about living in Võru? I can't tell anything which I particularly do not like. This year I don't like that the school has been moved to another building, which doubles the distance between my home and school. I like that Võru is such a small and quiet town, which makes it nice and secure to live in. Do you get any pocket money? I don't get any certain amount of pocket money. When I need to buy something or just want money, I ask my parents. Of course, I have mo...
