several students and their parents. Why mobile phones are necessary 1 Some students chat in English and find this helpful. 2 It might be necessary to phone home if a student has transport problems. 3 Students' parents might need to contact them urgently if some other emergency have had occurred Recommendations Everyone agrees that mobile phones can be irritating but they can be extremely useful at times. Students should check that phones are switched off before classes start. We do not believe they should be banned. Kristjan Heinrand 12b

Why learn English? Nowadays English plays a major international role. Personally I believe, that in order to survive in present society we have to, at least, know the basic English, because almost everything is based on English. Firstly English is the international language and knowing English shows the eruditeness of people, because every person who considers him or herself to be educated has learnt it. English has switched places with Latin, which once was the language of educated people. Not to mention the fact that people can use it for communication with eachother. In my opinion it is not necessary to learn that country's mother tongue while most of the people are able to talk in English. I find that English connects different people and helps us to feel like a big multicultural family. In addition to that it is a whole lot easier to find a job abroad, if you are fluent in English,

Watt hit upon the idea of condensing the steam in a separate place. This removed the need for heating and cooling, making the engine faster, safer, and it used a lot less fuel. A stone in Glasgow Green marks this spot, where the industrial revolution really began. Watt's engines were initially used for pumping water from copper mines. Later, the new cotton mills, which had been built near fastflowing rivers to take advantage of water power, almost all switched to steam. Gradually, mills began to move toward the centres of population. At first, steam power was used mainly for spinning, but eventually weaving was also powered by steam engine. By 1819, the year of Watt's death, there were 18 steam weaving factories in Glasgow, with 2800 looms. (This was excellent news for factory owners, but hundreds of unemployed handloom weavers were not so happy.) Despite his success, Watt was a rather insecure and jealous man, who
Young hacker Jonathan Joseph James Lets move on to Jonathan Joseph James was born on the 12 December, 1983. He was an American hacker who was the first juvenile incarcerated for cybercrime in the United States. He was a passionate computer geek, who started playing with family computer at the age of 6 and he switched his own computer from Windows to linux in middel school. He really liked computers and he said that the hard part isnt getting into the systems but its learning to know what it is that your doing. So he studid all these books therefore he knew Unix system and C programming like the back of his hand. James committed a series of intrusions into various systems, like BellSouth and the Miami- Dade school system. What brought him to the attention of federal authorities, however, was
350 floats and 15,000 costumed paraders take over the scene. Symbols The millions of colorful beaded necklaces thrown from floats are the most visible symbols and souvenirs of Mardi Gras. The tradition of throwing beads and small trinkets from Mardi Gras parade floats dates back almost as long as the parades themselves. Originally, the beaded necklaces were made from glass, but the Krewes switched to plastic in the mid 1900s. Throws started in the 1920s when Rex and a few other Krewes started throwing small trinkets. In addition, millions of cups, stuffed animals, plastic cups, small toys and even bags and toy coins known as "doubloons"are decorated with krewe logos and thrown to parade-watchers. Mardi Gras around the world In Ireland, Australia, and Canada, Mardi Gras is known as "Pancake Tuesday", while in Britain it is popularly known as "Pancake Day".
I think maybe nobody ever told him "Jazz playing on horn is very difficult, and probably not natural" or perhaps the phrase does not translate into Russian. I'd walk on a camel for a mile to hear this guy. ''Jazz Times Magazine wrote:“His control of the instrument, and his blowing creativity have set a new standard, even Julius Watkins, his idol never produced such results.” Arkady Shilkloper was born in 1956, in Moscow, Russia. He began to study alto horn at the age of six and switched to French horn in 1967. At the age of eleven he entered the Moscow Military Music School. One of most unusual Russian musicians, Arkady plays French horn, flugelhorn, alphorn and many more wind instruments. From 1978 to 1985 he was a member of the orchestra of the Bolshoi Theatre. With this world-famous orchestra and as a member of the Moscow Philharmonic Orchestra from 1985 to 1989, he undertook numerous worldwide concert tours.
English comes as my third language, and actually I met with it first almost at the same time they began teaching us French. But it was awkward and I'm not sure they themselves knew what they were doing or why. I can recall we cut out some pictures and glued them to a book and wrote some words up. I also recall the pronounciation was simplified for us, for example, they taught us "gööl" as the correct way to say "girl" etc. They never mentioned that it's not exactly correct... But well, then I switched schools and met the most important man of my life – my English teacher. He had three masters – in English, in German and in Physical Education. He had also written the school hymn. He was very stern with us and made us study like crazy. You made one tiny mistake, and it was "4", two mistakes made a "3" and so on. He was an awesome teacher. He said we can talk in his class as much as we want provided we do it in English. He also had us count the passing

Süntesaator Süntesaator Süntesaator on tuletis kreekakeelsest sõnast syntithetai kõnekeeles ka sünt, on muusikasmuusikainstrument, mille abil on võimalik luua elektroonilisest signaalist looduses eksisteeriva akustilise heli (muusikalise heli, müra või konkreetse loodus- või inimkeskkonna heli) imitatsioon või ka heli, millel looduses akustiline vaste puudub. Süntesaatori töö põhineb helisünteesil. Süntesaatorid jagunevad riist- ja tarkvaralisteks ehk virtuaalseteks süntesaatoriteks . Riistvaralised süntesaatorid jagunevad analoog- ja digitaalsüntesaatoriteks. Süntesaatori kontrollerina kasutatakse enamasti klaviatuuri, kontrollnuppudega paneeli, lintkontrollerit, hiirt või arvuti sõrmlauda. Klaviatuur võib olla süntesaatoriga integreeritud või ka eraldi aparaat, mis võib olla ühendatud ühe või mitme süntesaatori või arvutiga. Heli ja helisüntees Süntesaatorite töö põhineb erinevatel helisünteesi meetoditel. K...

It stays away from towns. Where it passes near Cooper Pedy in South Australia, it’s actually a tourist attraction, visited on bus tour. People go and touch it. Children like to climb it. The fence marks the dividing line between cattle (outside) and sheep (inside). Inside is where dingoes, legally classified as vermin, are shot, poisoned and trapped. Sheep and dingoes do not mix. Stations that once sheared 100.000 sheep suffered so many kills that their owners switched to cattle. Others fought back with massive poisoning campaigns and shooting drives. Stations reported annual kills of hundreds of dogs. Day after day people, singly or in pairs travel at the fence filling their days by patrolling at the fence. They fill in the holes, set the traps, replace post, close the gates, and shoot dingoes. Natural forces conspire against the fence. Floods wash it away, rust eats it up, blowing sand buries it, and falling trees crush it. Then there are the animals
important. Put simply, these students just aren't very interested in the hard work that goes with rock-solid reporting, and they usually disappear after a semester. Ambition helps. Newsrooms are known for being full of type-A personalities, people who are driven to get ahead and rise to the top. Again, I've had my share of ambitious students over the years, but a fair number of them decided there wasn't enough money in news to make it worth their while. More often than not they switched their majors to business, or headed for law school. So who does do well, at least in my journalism program? What kinds of students end up finding careers in news? Here are a few traits common to the successful journalism students I've seen over the years. They find their passion. I've had any number of students who, upon seeing their first byline in the student newspaper, have that moment when a light bulb switches on above their heads.
Shaun White Shaun Roger White (born September 3, 1986) is an American professional snowboarder and skateboarder. He is a two-time Olympic gold medalist. He rides regular stance, twelve and negative three degrees on his board. Addressing his perception of the nickname "The Flying Tomato", Rolling Stone wrote, "he used to embrace it, even wearing headbands with a flying- tomato logo, but he has grown tired of it." He has also been nicknamed as "animal", a reference to a character from the satirical puppet show The Muppet Show. Early life White was born in San Diego, California. His ancestry includes Irish and Italian. He was born with a Tetralogy of Fallot, a congenital heart defect for which he endured two open-heart operations before the age of one. He stands 5'8" (1.73 m) tall. White spent his formative years riding Okemo Mountain and Bear Mountain, small ski resorts found in Ludlow...

Bad Teacher Elizabeth Halsey (Cameron Diaz) is a Chicago middle school teacher at the fictional John Adams Middle School who curses at her students, consumes lots of alcohol, smokes marijuana, and only shows movies while she sleeps through class. She plans to quit teaching and marry her wealthy fiancé, but when he dumps her, she must resume her job as a teacher. She tries to win over substitute teacher Scott Delacorte (Justin Timberlake), who is also wealthy. Amy Squirrel (Lucy Punch), a dedicated teacher and colleague of Elizabeth, also pursues Scott while the school's gym teacher, Russell Gettis (Jason Segel), makes advances on Elizabeth which she rejects.[3] Elizabeth plans to get surgery to enlarge her breasts, believing she is being overlooked for women with larger chests. However, she cannot afford the $10,000 procedure. To make matters worse, Scott admits that he has a crush on Amy, only viewing Elizabeth as a friend. Elizabeth...

Seega digitaalmodem edastab info kahe tooni abil, mida on lihtsam edastada ja vastu võtta, sest eristada tuleb vaid kaht tooni. Raadio modem Otseeetri satelliidid, WiFi ja mobiiltelefonid kõik nad kasutavad modemeid, et olla ühenduses ja saata andmeid nagu paljud teisedki traadita ühendused. Kaasaegne telekommunikatsioon ja andmevõrgud kasutavad ära raadio modemeid, kus on vajalik pikamaa viidad. Sellistel süsteemidel on tähtis osa PSTN-s ehk Public switched telephone network ehk üldkasutatavad telefonivõrgud, kus kasutatakse siiani kiiret arvutivõrgu viita äärealadel, kus pole majanduslikult otstarbekas kasutada kiude. Isegi seal, kus on kaabel installeeritud, on võimalik saavutada parem tulemus või muuta teisi süsteemi osi lihtsamaks, kasutades raadiosagedusi ja modelleerimistehnikat kaabli kaudu. Koaksiaalkaablitel on väga suur ülekandekiirus, et digitaalsignaale kasutades muutub suureks
"I am become death, the destroyer of worlds." So said the physicist Robert Oppenheimer, who helped to invent the atomic bomb. The two bombs dropped on Hiroshima and Nagasaki in 1945 killed around 200,000 Japanese people. No other species has ever wielded such power, and no species could. The technology behind the atomic bomb only exists because of a cooperative hive mind: hundreds of scientists and engineers working together. The same unique intelligence and cooperation also underlies more positive advances, such as modern medicine. But is that all that defines us? In recent years, many traits once believed to be uniquely human, from morality to culture, have been found in the animal kingdom (see part one in this two-part series). So, what exactly makes us special? The list might be smaller than it once was, but there are some traits of ours that no other creature on Earth can match. No animal can get close to the devastatio...
The Pew Research Center projections attempt to incorporate patterns in religious switching in 70 countries where surveys provide information on the number of people who say they no longer belong to the religious group in which they were raised. In the projection model, all directions of switching are possible, and they may be partially offsetting. In the United States, for example, surveys find that some people who were raised with no religious affiliation have switched to become Christians, while some who grew up as Christians have switched to become unaffiliated. These types of patterns are projected to continue as future generations come of age. (For more details on how and where switching was modeled, see the Methodology. For alternative growth scenarios involving either switching in additional countries or no switching at all, see Chapter 1.) Over the coming decades, Christians are expected to experience the largest net losses from switching

Varasemate süsteemide puhul oli igal mobiilil oma fikseeritud number. GSMil oli eeliseid palju krüpteeritud kõnesid polnud enam võimalik (lihtsalt) pealt kuulata; müravaba kõnekvaliteet; rändluse (roaming) võimalus; andmeside võimalus; tänu pakkimisele mahub infot samadele raadiosagedustele palju rohkem jne. 1995. avati Eesti esimene GSM-võrk. 2,5G ehk GPRS pakett-kommutatsiooniga andmeside kasutamine (General Packet Radio Service). Enne oli GSM-võrgus kasutusel CSD (Circuit Switched Data ehk kanalikommutatsiooniga andmeside). Kui CSD puhul maksustati andmesidekanali lahtioleku aega (sõltumata sellest, kas infot liikus või mitte), siis GPRSi puhul andmete hulka. GPRS võimaldas CSDst umbes kümme korda kiiremat andmesidet 9800 bpsvs 115 kbps. 2,75 ehk EDGE (Enhanced Data Rates for GSM Evolution) võimaldas andmeedastuskiirust kuni 236,8 kbps. EDGE on tänagi Eestis kasutusel (juhul kui kiirem andmesidevõimalus puudub).

Wars film Star Wars (later renamed Star Wars Episode IV: A New Hope) in which BK sold a set of glasses featuring the main characters from the film. This promotion was one of the first in the fast food industry and set the pattern that continues to the present. BK's early success in the field was overshadowed by a 1982 deal between McDonald's and the Walt Disney Company to promote Disney's animated films beginning in the mid 1980s and running through the early 1990s. In 1994 Disney switched from McDonald's to Burger King, signing a ten film promotional contract which would include such top ten films as Aladdin (1992), Beauty and the Beast (1991), The Lion King (1994) and Toy Story (1995). A partnership in association with the Pokémon franchise at the height of its popularity in 1999 was one of the most successful in the industry, rivaled only by McDonald's/Ty Beanie Babies cross- promotion in 19992000. Shortly after the acquisition of Burger King by TPG Capital, L.P
under study (Tabel ). Individual boilers and stoves for wood and gas cover more than one-half of the heat use in households. Gas is the most widely used heating source for residences and it is expanding at the expense of district heating . Tabel shows that district heating has large problems with competitiveness and customer relations. Today, the DH consumption is just one-half of the previous use. Many district heating users switched to gas due to low gas prices and heavy, government-regulated DH price increases , whereas households and district heating plants had the same gas price. Error: Reference source not found. District heating production in Romania in 2005 Figure 5 shows that Romanian district heating production is completely based on fossil fuels.

persecuted for protesting against Shell and the Nigerian dictatorship over exploitation in their homeland. The Body Shop At HomeTM, the direct-selling arm, was launched in the UK in 1994, Canada in 1995, Australia in 1997, and USA in 2001. It has now rolled out in 48 states in the USA and is set to grow even bigger. The Body Shop continues to increase its environmental practices. In 2001, The Body Shop UK region and service centre head offices in Watersmead switched to Ecotricity providing them with energy from renewable sources. In addition, a number of The Body Shop® stores have now converted to green electricity while the rest of the stores are set to follow suit. Campaign successes include the Against Animal Testing campaign. The campaign led to a UK-wide ban on animal testing on cosmetic products and ingredients in November 1998 and led to the largest ever petition (four million signatures) being delivered to the European Commission in 1996.
minimalistic instrumental lineup, but proceeding albums have had a slower, more melancholic tone and they started experimenting with synthesizers and other, less traditional, forms of sound production (particularly after Black Market Music).The band have gained some measure of notoriety for the sexualities of its members (Olsdal is gay and Molko is bisexual) as well as for their excessive lifestyles and Molko's androgynous image, which are often referred to in their songs. In 1998, Placebo switched to the major label Virgin Records, and issued their album Without You I'm Nothing in November. It was another large seller in England and initially appeared to be the group's breakthrough in the US market, where MTV embraced the album's lead single "Pure Morning", but subsequent singles and videos failed to match the success of its predecessor.The singles "You Don't Care About Us", from Placebo (1996), and "Pure

98828 volts This is not exactly 3v, but it is as close as we can get with an 8-bit converter and a 5v reference. An 8-bit successive approximation ADC can do a conversion in 8 clocks, regardless of the input voltage. More logic is required than for the tracking ADC, but the conversion speed is consistent and usually faster. Dual-Slope (Integrating) ADC A dual-slope converter (Figure 2.4) uses an integrator followed by a com- parator, followed by counting logic. The integrator input is first switched to the input signal, and the integrator output charges toward the input voltage. After a specified number of clock cycles, the integrator input is switched to a reference voltage (VREF1 in Figure 2.4) and the integrator charges down toward this value. When the switch occurs to VREF1, a counter is started, and it counts using the same clock that determined the original integration time. When the inte- grator output falls past a second reference voltage (VREF2 in Figure 2.4), the

When the outside of the bath was thermally isolated and the same experiment was carried out, the temperature of the bath reached a temperature of approximately 44oC 2.2.2 Unsteady state experiments The water in the isolated bath was heated up to approximately 80 oC, which was measured with a calibrated thermometer. The electrical heater was then switched off and a given flow rate of water was set inside the coil. The experiment began with starting a timer from zero and reading the three temperatures (temperature of bath and the inlet and outlet temperatures of the water flowing inside the coil). Every other reading was taken with a five minute interval, until the bath had been cooled down to approximately 25 oC. It was repeated with four different agitation rates of 618 rpm, 980 rpm, 1342 rpm and 1703 rpm, respectively and each

dialects). Some of these features such as akanye and yakanye, a debuccalized or lenited //, a semivowel /wu/ and palatalized final /t/ in 3rd person forms of verbs are also present in modern Belarusian and some dialects of Ukrainian (Eastern Polesian), indicating a linguistic continuum. The city of Veliky Novgorod has historically displayed a feature called chokanye or tsokanye ( or ), in which /t/ and /ts/ were switched or merged. So, ('heron') has been recorded as . Also, the second palatalization of velars did not occur there, so the so-called ² (from the Proto-Slavic diphthong *ai) did not cause /k, , x/ to shift to /ts, dz, s/; therefore, where Standard Russian has ('chain'), the form [kep] is attested in earlier texts. Among the first to study Russian dialects was Lomonosov in the 18th century. In the 19th, Vladimir Dal compiled the first dictionary that included dialectal vocabulary. Detailed
• Took off their stocking caps • Ripped off ID numbers • Barricaded the door • Cursed guards Valvurite vastusammud Broke into cells, prisoners stripped naked, beds taken out, solitary confinement “Privileged cells” - prisoners given uniforms and beds back, allowed to wash and brush teeth, and allowed to eat food in front of other prisoners that were denied food temporarily (those least involved in the rebellion were given these cells) After half a day, the guards switched the good prisoners back into the bad cells and put the bad prisoners in the good cells to thoroughly confuse them...this also served to break the solidarity of the prisoners and make them question each others’ loyalties (were they informers?) Prisoners also were denied the right to use the bathroom; after “lights out” at 10pm, they had to use the bathroom in a bucket and were sometimes denied the right to empty it out Vang Nr 8612
something about things like bullying and theft at school. I mean who knows better than the students who does what and which punishment would really work? And most of all it would make teachers listen and respect our opinions and feelings. I wish our school would allow us something like that. Speaker 4 We were all surprised at Korczak's instruction to gather in the X-ray lab. The doctor arrived, bringing along a four-year-old from his orphanage. The X-ray machine was switched on and we saw the boy's heart beating wildly. He was so frightened by the strange people, the dark room and the machine. Speaking softly, Korczak told us: `Don't ever forget this sight. How wildly a child's heart beats when he is frightened. It does even more so when the child reacts to an adult's anger, not to mention the fear of punishment.' Then, heading for the door with the boy's hand in his, he added, `That is all for today!' That lesson was imprinted on our minds forever.
have bred pure "Golden Siamese" for 5 generations. Having proven his point, he stopped breeding, though his cats were popular with pet buyers. In the 1960s and 1970s, the Tonkinese was revived in Canada and the USA by crossing Siamese with Burmese in spite of opposition from breeders of both Siamese and Burmese who viewed them as embodying everything they were trying to breed out of those two breeds. In the mid 1960s, Jane Barletta of New Jersey switched from the increasingly extreme Siamese to breeding the more moderate Tonkinese. At about the same time, Margaret Conroy in Canada bred a female Burmese to a Seal point Siamese as she was unable to find a suitable Burmese stud in her locality. Her tan-bodies cats bred true for 5 generations and were dubbed Tonkanese (with an "a"). The original cats were Sable (US: Natural Mink), but crosses between Blue Burmese and Blue Point Siamese introduced Blue Tonkinese. Later on, the

But that wasn't why I jerked my hand away so quickly. When he touched me, it stung my hand as if an electric current had passed through us. "I'm sorry," he muttered, pulling his hand back immediately. However, he continued to reach for the microscope. I watched him, still staggered, as he examined the slide for an even shorter time than I had. "Prophase," he agreed, writing it neatly in the first space on our worksheet. He swiftly switched out the first slide for the second, and then glanced at it cursorily. "Anaphase," he murmured, writing it down as he spoke. I kept my voice indifferent. "May I?" He smirked and pushed the microscope to me. I looked through the eyepiece eagerly, only to be disappointed. Dang it, he was right. "Slide three?" I held out my hand without looking at him. He handed it to me; it seemed like he was being careful not to touch my skin again. I took the most fleeting look I could manage. "Interphase
efghiklmnopqrstuxyzwabcd ........................ zwabcdefghiklmnopqrstuxy wabodefghiklmnopqrstuxyz Trithemius used this tableau for his polyalphabetic encipherment, and in the simplest manner possible. He enciphered the first letter with the first alphabet, the second with the second, and so on. (He gave no separate plaintext alphabet, but the normal alphabet at the top can serve.) Thus a plaintext beginning Hunc caveto virum . . . became HXPF GFBMCZ FUEiB. ... In this particular message, he switched to another alphabet after 24 letters, but in another example he followed the more normal procedure of repeating the alphabets over and over again in groups of 24. The great advantage of this procedure over Alberti's is that a new alphabet is brought into play with each letter. Alberti shifted alphabets only after three or four words. Thus the ciphertext would mirror the obvious pattern of repeated letters of a word like Papa ("Pope"), or in
