Transmission and differential Rene Põlluvee and Kaupo Kormik 43AT 2015 Transmission ● The transmission is a mechanical component designed to transmit power from a vehicle’s engine to the drive axle, which makes the wheels drive the vehicle.Some vehicles use a clutch to connect and disconnect the transmission to the engine, controlled through a foot pedal next to the brake pedal. These vehicles have a manual transmission. If your car doesn’t have a clutch pedal, it has an automatic transmission.Automatic transmissions depend on a special fluid called ATF to cool and lubricate the moving parts inside. But the fluid does more than that: In fact, it’s no exaggeration to say that the fluid actually drives the vehicle. So there’s little doubt that the fluid is very important to the transmission’s ope...
Intelligence and psychopathy: a correlational study on insane female offenders. C. SPIRONELLI, C. SEGRÈ, L, STEGAGNO ja L. ANGRILLI Spironelli, C., Segré, D., Stegagno, L., Angrilli, A. (2014). Intelligence and psychopathy: a correlational study on insane female offenders. Psychological Medicine, 44 (01), 111-116. Antud uurimuse eesmärgiks oli uurida kriminaalse taustaga naiste intelligentsuse ning psühhiaatriliste käitumismustrite vahelist seost. Taustinfona oli nii palju teada, et siiani ei ole ühtset arusaama IQ ja psühhiaatriliste käitumismustrite olulise seose suhtes ning peamiselt on seda uuritud meessoost kurjategijate hulgas (ning uuringutes käsitletakse enamasti crystallized IQ tulemusi). Uurijad püstitasid hüpoteesi, et esineb negatiivne korrelatsioon psühhiaatriliste käitumismustrite ning fluid IQ vahel ja testisid oma hüpoteesi kinnipeetud naiskurjategijate peal. Uurijad viisid läbi seosteuuringu nin...

Õpilase nimi: Peedu Siimo Klass: 8 Tööleht „Üleslükkejõud“ Uuri järgmist mudelit: http://phet.colorado.edu/sims/density-and-buoyancy/buoyancy_en.html Sul on mudeli töölaual 2 keha (puust ja kivist kuup). Kaalule asetades saad määrata mõlemale kehale mõjuva raskusjõu. Kui keha vette paned, siis näed, kui palju tõuseb veetase anumas. Algselt on seal 100 l vett (vee puhul võib võtta, et 1 l = 1 dm3). Keha lisamisel vette tõuseb veetase nii palju, kui suure koguse (ruumala) vett keha välja tõrjub. Kuupe saab muuta järgmiselt: sama massiga, sama ruumalaga ja sama tihedusega (linnuke soovitud valiku ette). Akna all vasakus nurgas olevas menüüs saab märkida ära, milliseid jõude joonisel näidatakse (nooltega) ning kas näidatakse ka jõudude ja/ või keha massi väärtust (linnukesed soovitud valikute ette). "Fluid" paneelis on võimalik määrata keskkonnaks ka vesi (vaikimisi) või õli. Vasta küsimustele: Lülita mudeli...
Does the Higgs Field do something? Dmitri Martila ([email protected]) Latter affiliation: Tartu University (Dated: September 16, 2016) Abstract Is studied the possibility to replace the Dark Matter and the Dark Energy with the single Higgs Field (or fields). The study in close direction was made in arXiv:1603.06242, and in “The Higgs Boson May Disintegrate into Dark Matter” (the Google News). Just because the physics is physical, then the Higgs Field do exist, do exist throughout the spacetime, and even acts on curvature of the spacetime even in the cosmic void (the places without the baryonic matter). In case of the places with the baryonic matter the Higgs Field emits the Higgs Boson to give the baryonic matter the right amount of mass: therefore the density of the Higgs Fie...

Dear Neander Taal, Once again, I find disappointment. Once again, I find no satisfaction. Once again, I find that my motivations for writing this letter are not of insult or hatred, but of the deepest love for mankind and the truest concern for its future generations. It is requisite, even in this summary sketch, to go back a few years to see how I admit I have a tendency to become a bit insensitive whenever I rebuke Laivi Tuvahe for trying to leach integrity and honor from our souls. While I am desirous of mending this tiny personality flaw, by brainwashing her apologists with anarchism, Laivi makes them easy to lead, easy to program, and easy to enslave. I would like to comment on Laivi's attempt to associate hooliganism with Dadaism. There is no association. Should we be concerned that Laivi wants to destroy that which is the envy of--and model for--the entire civilized world? I'll answer that question for you: Yes, we shoul...

Durability of concrete In this presentation I'm focusing on the durability of concrete. First I'll give a brief overview of concrete, we have to know what does it actually means and where is it used? (slide) Basically concrete is a construction material composed of cement, aggregate (generally gravel, limestone, or granite, plus a fine aggregate such as sand) also water, and chemical admixtures.(slide) Concrete is used to make pavements, architectural structures, foundations, roads, bridges, marine- and parking structures, brick/block walls and footings for gates, fences and so forth. Mainly it is used because of its high durability and availability, but also because it is cheaper than to use wood for example. Concrete is used more than any other man-made material in the world.(slide) Moving on, the durability of concrete can be defined as the ability to remain serviceable for at least the require...
My analysis of the article " Why Ebola is so dangerous" I chose this article because this theme is very current in our society, and many people are dying due to the disease called Ebola. The theme is very intriguing and I hope it interests people, because it definitely interests me. I think that this article makes people more aware of the disease and hopefully helps to put a stop to Ebola. Ebola virus disease, or simply Ebola, is a disease of humans and other primates caused by ebolaviruses. Signs and symptoms typically start between two days and three weeks after contracting the virus, as a fever, sore throat, muscle pain and headaches. Then, vomiting, diarrhea and rash usually follow, along with decreased function of the liver and kidneys. At this time, generally, some people begin to bleed both internally and externally. Death, if it occurs, follows typically six to sixteen days after symptoms appear and is often due to low blood ...

Most types of truck air brakes are drum units, though there is an increasing trend towards the use of disc brakes in this application. The compressed air brakes system works by drawing filtered air from the atmosphere, compressing it, and holding it in high-pressure reservoirs at around 120 PSI. When needed for braking, this high pressure air is routed to the operating cylinders on the brakes, which ...

Innovatsioon ja tööstuslik evolutsioon James M. Utterback’i „Mastering the Dynamic of Innovation“ peatükk 4 „Innovation and Industrial Evolution“ kokkuvõte. Innovatsioonitegevuse dünaamika… ehk dünaamiline suhe on toote innovatsiooni, turustamise ja tekkivate ning konkureerivate firmade vaheline seos, kus iga osapool mõjutab ma tegevusega konkreetse toote innovatsiooni. Sellist suhet seostatakse ajalooliselt eelkõige kirjutusmasina ja elektrilise valgustuse (hõõgpirn) innovatsiooniga. Seda suhet iseloomustab eripära, et ka juhul kui innovatsiooni fookus toote evolutsiooni ajal muutub, siis dünaamiline suhe mõjutavate aspektide vahel on jääv. Innovatsioonitegevuse dünaamika parimaks näiteks tänapäevast on arvuti (personal computer) areng, mille fookus on ajapikku muutunud, kuid milles mängivad olulist rolli erinevad tark- ja riistvara tootjad ning tarbijad. Paljudes teadusuuringutes on püütud tuua välja standardseid innovatsioone en...

Kordamine füüsikalise ja kolloidkeemia protokollide vastamiseks Vaja on vastata 1) 1. Soola integraalse lahustumissoojuse määramine 1. Esimene termodünaamika põhiseadus. Termodünaamika esimene seadus sätestab, et keha siseenergia (U) saab muutuda tänu soojushulgale (Q), mis saadakse väliskeskkonnast ning tööle (A), mida süsteem teeb välisjõudude vastu:U = Q - A, kus Q on soojushulk, mille keha saab väliskeskkonnalt ning A on töö, mida keha teeb välisjõudude vastu (juhul kui keha annab soojust ära, siis on Q negatiivne; kui välisjõud teevad tööd, siis on Apositiivne). Termodünaamika I seadus on üldise energia jäävuse seaduse konkreetne väljendus termiliste protsesside korral. Jäävuse seaduse järgi on süsteemi energia tema oleku üheseks funktsiooniks. Väliskeskkonnast isoleeritud süsteemi koguenergia on jääv. Mitmesuguste protsesside korral sellises süsteemis võib energia muunduda ühes...

Sooline defineerimine Arutelu Sarah Raichmann Inglise keeles on ilmekalt kaks sõna kirjeldamaks kellegi sugu – sex ja gender. Sex, nagu arvamusliider Marina Watanabe kirjeldab, on bioloogiline. See ei tähenda, et see ei oleks binaarne või vaid üheti mõistetav, kuid et see on seotud otseselt inimese füüsisega. Gender on aga sotsiaalselt kujundatud arusaam kellegi soost. Hea näide sellest on näiteks arusaamad mehisusest ning naiselikkusest erinevates kultuurides. See tähendab, et miski mida meie arvame olevat mees või naine spetsiifiline ei pruugi olla samamoodi mõitetav mõnes teises kultuuriruumis.1 Siinkohal tasub täpsustada, et ei sex ega gender ei ole kuidagi seotud kellegi seksuaalsusega või nende seksuaalse orientatsiooniga – mis siin all on mõeldud on vaid nende sugu ning enesedefineeringut kas mehe või naisena. Essentsialism on lähtumine eeldusest et sugu (või üldse mingisugune olemus) on iseloomustatav olemuslike omadustega, s...
NEUROBIOLOGY AUXILLARY GLOSSARY ACETYLCHOLINE – A neurotransmitter in both the brain and peripheral nervous system* (PNS). In the brain it helps regulate memory, whilst it controls the actions of skeletal and smooth muscle within the PNS. ACTION POTENTIAL – An electrical phenomenon which occurs when a neurone is activated and temporarily reverses the electrical state of its interior membrane from negative to positive. An electrical charge travels along the axon to the neurone’s ending (terminal) where it triggers the release of a neurotransmitter* and then disappears. ADRENALINE (U.S. - Epinephrine) – A hormone released by the adrenal medulla* and a neurotransmitter acting at the level of the autonomic nervous system and the brain. ADRENAL CORTEX – The outer layer of the adrenal, a small endocrine gland located near the kidney. It produces and secretes several horm...
Philip Larkin’s Poetry: Themes, Form, Style, Imagery and Symbolism Author: Sandra Olivares González Tutor: Jesús Marín Calvarro Degree in English Studies, English Department, Faculty of Philosophy and Letters, University of Extremadura Cáceres, 29th January 2016 Philip Larkin’s Poetry: Themes, Form, Style, Imagery and Symbolism The aim of this work is to obtain some characteristics of the poetry of Philip Larkin, such us the origin of his themes, the way in which he writes his poems and the symbolism he uses (which is a very controversial topic because some assume that he does use it, while some others say that he uses it in an ironic way). In this work we tried to make a revision on the vision of Larkin through the studies that had been made on him, and on the basis of it we can say, that the voice of ...
Filmikunsti ajalugu 31.01.12 The age of pioneers: the early history of film How the horses helped to ivent the cinema. Cinema was invented by accident. 1872, west coast: leland standford, party, rich people, end of the 19 century, bored. Stanfrod talks friends about horses: problem: question is, what happens with the hooves while its moving, running. Bet, with eyes, can't settle this. Cannot ever see if the hooves touch the ground. Stanford has enough money, hires most famous photographer. Eadwerd muybridge, comes to usa. Tells him to settle this with photography. That time with photography you cannot get any informatio either. Started to install boxes, in each box, there was a camera. Does the hooves touch the ground or not? Fast shutter, can freeze the moment. Makes fast shutters, to record this. Finds solution, hooves are touching. The prerequisites for cinema: camera(edison and dickson), film stock that is flexible and stable to ru...
VUNDAMENDI ISOLEERIMINE REFERAAT Õppeaines: HOONE OSAD Ehitusteaduskond Õpperühm: EI-41 Juhendaja: Jüri Tamm Tallinn 2012 SISSEJUHATUS Vundamentideks nimetatakse hoonete maa-aluseid konstruktsioone, mille ülesandeks on hoone koormuse üleandmine alusele. Vundamentidele mõjuvad hoone konstruktsioonidelt tulenevad vertikaalkoormused, horisontaalne mullasurve, pinnasega edasiantav vibratsioon, pinnasevee mõju, perioodiline külmumine ja sulamine (soklile), pinnasevee keemiline agressiivsus, sise- ja välistemperatuuri koosmõju, keldriruumide niiskus jne. Vundamendid peavad olema tugevad, püsivad, vastupidavad, odavad ja maksimaalselt industriaalsed. Vundamentide projekteerimisel tuleb lähtuda hoone või ehitise maapealse osa otstarbest ja selle vajumistundlikkusest. Vundamendid projekteeritakse kas monteeritavatena või kohalvalmistatavatena. (E.Talviste: 81) Vundametide lähedal on soo...
1)Main machinery On a ship, the engine room, or ER, is the propulsion machinery spaces of the vessel. To increase the safety and damage survivability of a vessel, the machinery necessary for operations may be segregated into various spaces. The engine room is one of these spaces, and is generally the largest physical compartment of the machinery space. The engine room houses the vessel's prime mover, usually some variations of a heat engine - diesel engine, gas or steam turbine. On some ships, the machinery space may comprise more than one engine room, such as forward and aft, or port or starboard engine rooms, or may be simply numbered. 1.1)Main engine The engine room of a motor vessel typically contains several engines for different purposes. Main, or propulsion engines are used to turn the ship's propeller and move the ship through the water. They typically burn diesel oil or heavy fuel oil, and may be able to switch between the two....
Since the invention of the internal combustion engine, automotive engineers, speed junkies and racecar designers have been searching for ways to boost its power. One way to add power is to build a bigger engine. But bigger engines, which weigh more and cost more to build and maintain, are not always better. Another way to add power is to make a normal-sized engine more efficient. You can accomplish this by forcing more air into the combustion chamber. More air means more fuel can be added, and more fuel means a bigger explosion and greater horsepower. A turbo/supercharged engine produces more power overall than the same engine without the charging. Both superchargers and turbochargers do this. The difference between the two devices is their source of energy . TURBOCHARGER When people talk about race cars or high-performance sports cars, the topic of turbochargers usually comes up. Turbochargers also appear on large diesel engines. A t...

Social Problems Crime In the sociological field, crime is the breach of a rule or law for which some governing authority or force may ultimately prescribe a punishment. The word crime originates from the Latin crimen. When society deems informal relationships and sanctions insufficient to create and maintain a desired social order, there may result more formalized systems of social control imposed by a government, or more broadly, by a State. With the institutional and legal machinery at their disposal, agents of the State can compel individuals to conform to behavioural codes and punish those that do not. Various mechanisms are employed to regulate behaviour, including rules codified into laws, policing people to ensure they comply with those laws, and other policies and practices designed to prevent crime. In addition are remedies and sanctions, and collectively these constitute a crimi...
Rational Use of Diagnostic Tests Screening tests Diagnostic tests are often used to screen asymptomatic patients and identify risk factors for occult disease. Screening tests should be generally noninvasive, inexpensive, and of minimal risk to the patient. Screening tests should have high diagnostic sensitivity, which means few false negative results would be expected, as the goal of testing is to rule out the presence of disease. Screening tests should be used to screen for diseases that (1) have serious consequences if left undetected, (2) are reasonably prevalent within the population, and (3) have treatment options readily available. Should a positive result be obtained, a more accurate, confirmatory test should then be performed. One example of a screening test would be the urine cortisol-to-creatinine ratio (Cort:Crt)u, which is used to screen symptomatic patients for canine hyperadrenocorticism.[1,2] The (Cort:...

1 Wave energy Introduction to wave energy There are several possibilities to harvest different forms of energy from the sea. One of these options is the usage of waves for the generation of electricity. The devices needed to perform this task are called wave energy converters. Wave energy is indirect solar energy in twice. At first there is the wind, which is caused by variations in atmospheric pressure due to a differential solar heating of earth's surface by the sun. Different regions of pressure drives a force which rises a movement of atmospheric air masses that causes the earths wind system. If wind strikes over the surface of an open water, waves are induced. First they are very flat with only a low level of energy. When there is a long distance over the water on which wind can attack the small ones, they became bigger and bigger with a l...
