What is wrong with current school education?

What is wrong with current school education? School education right now, like democracy, is not perfect. It has to be perfected all the time, according to the ways of life, which are always changing. There definately is not a certain perfect solution. Firts problem in current education system coul be that students are put into a „box“. Everyone gets graded by a certain standard, if you can not reach that line, then yo have failed. This is the fairest way, at least in concept. But not all the people have same abilities and strengths. Education should be more personal, focusin on a certain students talents and strengths and trying to develope those, so that the children could reach their full- potential and would always be encouraged to follow their heart in life

The black Death(1340s)

The black Death(1340s) Laura Runthal Overview  Originated in 1338 in Kyrgyzstan.  It spread by way of the Silk Road or by ship to Europe.  By the end of 1346 it had reached the seaports of Europe.  In 1348 the disease spread northwest across Europe, including England.  It killed between 75 and 200 million people by current estimates.  The Black Death was one of the most devastating pandemics in human history, peaking in Europe between 1347 and 1350.  The speed with which the disease could kill was terrifying to population of the medieval world.  Infected people can spread the disease through the air by coughing, sneezing, or just breathing!  When there was a infected in the house, a red cross was painted on the door.  Because of black spots, the disease

Piletid vastustega

Ticket No1 1)The characteristic is called output characteristic or volt-ampere charateristic of a Rectifier Diode. 2)Rectifier Diode. 3) A is called Anode and C is called Cathode. An Anode has positive potential and therefore collects electrons in the device. Cathode has negative potential and therefore emits electrons to anode. The symbol looks like an arrow that ponts from the anode to the cathode, and reminds that conventional current flows easily from the p side(anode) to the n side(cathode). BIASING. Forward biasing. If the current in a diode is too large, excessive heat will destroy the device. Even approaching the burnout current value without reaching it can shorten its life. Therefore manufacturer's data sheet specifies the maximum forward current, that diode can withstand. This average current IF is the rate a diode can handle up to the forward direction when used as a rectifier

Sustainability aspects of biofuels

Margit Tepner k0848752 Sustainability aspects of biofuels 1. Introduction The literature review will discuss the sustainability aspects of biofuels. Food production will be the main concern as it is the most debated issue, but other aspects, such as land use change and water consumption will be also considered as they are essential aspects in the biofuels sustainability criteria. The review will discuss the viability of biofuels based on the current technologies. Second-generation biofuels are not yet commercially viable and therefore will not be discussed; although they could significantly improve the sustainability of biofuels when they break through to the industrial scale. 2. The scale of biofuels production 2.1. Drivers of biofuels production Lal (2010) stated that "three inter-connected challenges face humankind in the 21st century": food security, climate change, and energy security

Railgun

little history and the recent advancements in railgun related science. 3 1. What a railgun basically is A railgun is an electrically powered electromagnetic projectile launcher and a large electric circuit, made up of three parts: a power source, a pair of parallel rails and a moving armature. Along the pair of parallel conducting rails a sliding armature is accelerated by the electromagnetic effects of a current that flows down one rail, into the armature and then back along the other rail. Railguns have long existed as experimental technology but the mass, size and cost of the required power supplies have prevented railguns from becoming practical military weapons. However, in recent years, significant efforts have been made towards their development as feasible military technology. For example, in the late 2000s, the U.S. Navy tested a railgun that accelerates a 3

Argumentative presentation: Estonia does need a nuclear power station

Argumentative presentation: Estonia does need a nuclear power station Good evening. My name is Margus and I will be talking to you about why does Estonia needs a nuclear power station. My talk consists of 3 parts: the current situation, renewables and how can nuclear power save Estonia from an energy crisis. My talk will last for 2-3 minutes and questions can be asked at the end. Power consumption is increasing exponentially in all civilised countries. Estonia's coal based power generation is becoming obsolete in the near future. The question arises : "Where will the future generations get the energy that they need?".

Report on Exercises 2 - Diodes

-18 -20 U ac, V Figure 5. Volt-amphere characteristics, reverse biased Conclusion Multisim gave us a virtual diode with the idealized symmetrical output characteristic. This means that if the voltage drops across anode-cathode are bigger than the knee voltage, then the current increases rapidly. But if not, then only very small current occurs. In the reverse biased, the voltage across the diode could be large, but only a small current occurs. is obtained as 0,57V from figure 4, which is made by the data we can see from table 1. 2.2 Series clippers VD f = 9 kHz R = 96 k US = 10 V

*An organisation must remain dynamic because the product is the only key to the organisation's solvency and profitability. *Company and consumer are independent because no matter how else the organisation runs itself cost-effecitively and sensibly, if the product is not selling well then the money simply will not be coming in. *Successful product management depend on the organisation knowing how and if the current product range meets consumer and organisational objectives. *One way if the current product range meets consumer and organisational objectives is to conduct detailed benefit analysis segmentation. *Differences between strategy and tactical activities are: strategy is long-term planning and tactical is short-term planning. *Product-market strategy represent a decision about the current and future direction of the organisation. *To minimise costs at the outset, a sound marketing approach will usually attempt to increase profits and cash flow from existing markets.

Alalis- ja vahelduvvool iseseisevül elektrotehnika

TALLINNA POLÜTEHNIKUM Alalis- ja vahelduvvool aruanne nimi klass TALLINN 2013 Alalisvool Alalisvool on elektrivool, mille suund ajas ei muutu. Alalisvool võib olla püsiva suurusega, näiteks keemilise vooluallika korral, või teataval määral pulseeriv, kui seda saadakse vahelduvvoolu alaldamisel. Pulseervool on küll ühesuunaline, kuid tema tugevus muutub perioodiliselt. Alalisvoolu rahvusvaheliselt kasutatav tähis on DC (inglise k sõnadest direct current). Alalisvoolu tingmärgis väljendab pidev kriips muutumatut ja katkendkriips pulseerivat voolu. Alalisvooluga töötab praegu veel enamus transpordivahendeid ­ elektrirong, tramm, trollibuss. Elektrienergia saadakse nende jaoks aga vahelduvvooluvõrgust alaldusalajaamade kaudu. Alalisvooluga töötavad ka elektrokeemilised ja galvaanikaseadmed.

Elektrivool - laengukandjate korrapärane liikumine

Elektrivool Elektrivool on positiivse või negatiivse elektrilaenguga laengukandjate korrapärane liikumine. Laengukandjate korrapärast liikumist elektri- või pooljuhis elektrivälja mõjul nimetatakse juhtivusvooluks. Elektrilaenguga laetud makroosakeste või kehade liikumist vaakumis või keskkonnas, millel puudub elektrijuhtivus, nimetatakse konvektsioonvooluks. Seotud elektrilaengute ehk dielektrikute aatomite ja molekulide koostisse kuuluvate osakeste elektrilaengute ning ioonvõrega kristalliliste dielektrikute ioonide laengute liikumist dielektrikus, mis muudab dielektriku polarisatsiooni, nimetatakse polarisatsioonvooluks. Elektrivoolu iseloomustavad suurused:Elektrivoolu iseloomustavateks ja mõõdetavateks füüsikaliseteks suuruseteks on voolutugevus, voolutihedus ja pinge. Elektrivooluga kaasnevad nähtused:Elektrivooluga kaasneb alati magnetväli.Elektrivoolud kui magnetvälja allikad jagunevad omakorda makroskoopil...

Kontserdi retsensioon

Young on siimaani AC/DC koosseisus. Ta mängib soolokitarri. Hetkel on lisaks temale bändis veel Cliff Williams, Brian Johnson, Stevie Young ning Chris Slade. Kuigi tavaliselt peetakse bändi hard rocki ja heavy metali teerajajaks, liigitavad liikmed enda muusikat rohkem rock'n'rolliks. AC/DC albumeid on müüdud üle 200 miljoni eksemplari. Album ,,Back in Black" on maailma paremini müünud albumite hulgas teisel kohal. Nimi AC/DC tuleneb ingliskeelsetest sõnadest alternating current/direct current, mis tähendab vahelduvvool/alalisvool. Väidetavalt soovitas seda vendadele Youngidele nende õde Margaret, lugedes seda lühendite paari õmblusmasinalt. AC/DC on võitnud palju erinevaid auhindu. Näiteks on nad saanud parima rokkbändi tiitli. Kontsert algas AC/DC uue albumi nime kandva looga ,,Rock or Bust". Pärast seda esitati veel mitmeid lugusid uuelt albumilt. Seejärel kõlasid AC/DC vanemad lood, mis kütsid tohutult publikut üles

My analysis of the article “ Why Ebola is so dangerous”

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

Maailmausundite statistika 3 - prognoos

Why Muslims Are Rising Fastest and the Unaffiliated Are Shrinking as a Share of the World’s Population The religious profile of the world is rapidly changing, driven primarily by differences in fertility rates and the size of youth populations among the world’s major religions, as well as by people switching faiths. Over the next four decades, Christians will remain the largest religious group, but Islam will grow faster than any other major religion. If current trends continue, by 2050 …  The number of Muslims will nearly equal the number of Christians around the world.  Atheists, agnostics and other people who do not affiliate with any religion – though increasing in countries such as the United States and France – will make up a declining share of the world’s total population.

Lessons for the future

Lessons for the future Education seems to be in government's, media's and people's spotlight all the time. Times change and education, as one of the most important areas of our society, needs constant reforming. Nowadays, the main focus seems to be on subjects like maths, physics, chemistry etc. because of current IT-era demands more knowledge in those regions than in humanities. I agree that Estonia's government's steps towards making maths and physics our school- system's top priority is quite right, but I think that there can be a lot more done to improve our educational structure. I find that Estonian schools should pay more attention to teaching our children current state in our political landscape. Kids, who go to school, are our future and soon-to-be full- right voters in national elections

the use of a famous fashion designer's name, including examples as the Pierre Cardin AMC Javelin, the Oleg Cassini AMC Matador, or the Lincoln Continental in Givenchy or Bill Blass versions. Typical elements that may be included in a trim package include: · Special paint, some with the appearance of pearl, others showing colour variations depending upon light angle · Paint patterns using multiple colours--two-tone or three-tone (out of current favour) · Aluminium, plastic, or stainless steel trim to divide paint regions (out of current favour) · Applied graphics on printed plastic sheeting with adhesive backing · Pin striping, usually applied as a dealer add-on using special plastic tape and a removable backing · Plastic bumpers painted the same colour as the vehicle body, rather than a matte black (now mostly included in the base level vehicle)

URO Security Council kriis, United nations Legitimacy crisis

Legitimacy! AND UNITED NATIONS CRISIS In this article, we examine the current debate regarding the legitimacy crisis facing the UNSC. We consider its most usual manifestation, namely that the Council faces a crisis of legitimacy because of its inability to constrain the unilaterally inclined hegemonic United States. But we also examine the converse argument that it is the whole UN collective security mechanism (rather than just the Council) that is in crisis. According to this, it is the failure to

Dioxins and furans in the atmosphere

Dioxins are widely encountered toxic substances. They are found in all environmental compartments, are persistent and, being fat soluble, they tend to accumulate in higher animals including humans. Their resistance to degradation and semivolatility means that they may be transported over long distances and give rise to transnational exchanges of pollutants. In addition, dioxins which were released into the environment many years ago are still contributing to current exposure. Even very small dioxin concentrations can cause negative effects on the environment and on human health, in particular on the most vulnerable groups like children. Human health effects include impairment of the immune system, the nervous system, the hormonal system and the reproductive functions. Dioxins are also suspected of causing cancer. How Are We Exposed to Dioxins? Although formation of dioxins is local, environmental distribution is global.
