I had to give my kano girlfriend a break when I realised she was too religious. I called it a quit, till we met one day at my HOD's office and she started apologizing. she came with her friends, seeing how shy she used to be, I opened it up, I told her friends that she is my friend, I could see the fears caused by being shy, the confidence too, she lost herself, for the very first time, we sat together, she looked at me eyeballs to eyeballs. Shame gone, fears gone. Her beautiful face was glaring, yes, she didn't come with hijab, she wore their native dress, with her shoes and hand bag matching the dress. She apologized to me, she told her friend that I will soon convert to Islam. I looked at her, she knows it's practically impossible, she demanded that I sent her a success message. it was exam time. Day by day, I kept receiving calls and messages from ladies, my students and those that collect my number from their friends, will I still keep myself am I about to eat the forbidden fruit? why will I break my virginity to a northern girl?? this questions only time can answer |
Dream2:thanks |
I must acknowledge the fact that Kano natives are good. They can relate with u and make u happy. I have met so many of them. They brought gift to me during Sallah, we went out together to see the Emir as he went to his mothers home in Dorayi. it was fun celebrating Sallah here, they exhibited their culture to the peak, everywhere was bubbling but no excitement. They cooked their best food. But one thing I realised is that, majority went to sabon gari both to drink and for party. The same sabon gari they called an evil place, there I saw their girls in swimming pools, with no hijab, nothing. I couldn't believe it, neither will u believe it. |
Gentlemen, I have never seen a more religious place like Kano. Everything is religion. The neutral ground for starting any thing is if u r in same religion with them. my Kano girlfriend amused me so much. we don't discuss anything apart from her religion. she spend most of our time talking about how her religion is the only thing that we keep us together. Justifying my earlier stand, I took a time during my revision class to talk about Kano. I asked my class of 100 students when they start islamiya and western education, I was told it begins from birth. That's the first thing they do. it was a risk but I discussed religion with my students, I asked them questions justifying my earlier take. I was supervising a class, one of the student came with a baby, due to pity, I backed the baby, during d exam, I asked her when the child will start school and which school, I was told Islamic education at age three. |
Welcome back. The thread is about to get hot again. Am back with full strength, experience and stories to tell. Am sure u will enjoy it. |
Opiletool:Please, help forward same to njokuchuks4u@gmail.com |
Topmostt:Please can u forward the material to njokuchuks4u@gmail.com. I am most grateful |
PDP accused buhari of going against court rulings, are they planning to do same?? Justice Okon Abang is doing the right thing. We must set things right and it's now. I don't even know why some youths come in here to defend the very people that kept us where we are today. If they have no confidence on Justice Okon Abang, why then did they have a lawyer and even go to the extent of making several prayers and even defending themselves. when judgement didn't favour them, they call Okon Abang names. |
Well I don't think there is any contribution, but one thing I know is that most things in Christianity has helped channel science Infact most scientists say that magic is where science has not reached. They are in different course but religion must agree with science. Christianity deals with belief system whereas science deals with reality, things we can mass produce. For instance, it's not all Christians that can do miracle, like healing the sick, prophesy and so on. But when a phone is produced in china for instance, with same procedure, that same phone can be produced everywhere around the world. science is helping us use our brain. Left for religion, we would still be in stone age but science help us think and fulfill the purpose of God. For a Christian, rain comes from heaven, but for a scientists like me, it comes from the cloud and nowhere beyond the troposphere but a handiwork of God. All things science does is what nature has placed for us. Science help us understand and explore them more. Though science is trying to prove the non existence of God, but at the end, it will end up proving the existence of God In conclusion, Christianity or religion has no impact of science, science only try to prove things people believe in religion.

JSoE:Why will I comment when someone has openly raped modern physics. It is totally wrong for him to take on d ignorance of majority to deceive them. He is wrong., Infact I have to copy and paste what he said on my class group, and you will not like to read what they said about t. If he is a physicist, let him open a thread in d science section. Infact everything the op said has NOTHING to do with the schrodinger equation. they are mere believes people have. it's just like saying that the existence of God has been explained by S.E. it's wrong. And for your lecturer teaching you Quantum mechanics in first year, I would like to know the school but I still maintain that it is wrong. Infact I have listened to lectures on quantum mechanics from MIT, Stanford university, IIT, their whole series of semester lecture on quantum mechanics, none were taught to first year physics students let alone non physics students. if it were the only course you will do in ur first year, none of u in d class will understand it. |
GogobiriLalas:But do u think that S.E has anything to do with what the op stated? I don't. I have solved schrodinger equation for different potential energy, studied S.E yet I haven't come across how it can be applied to the things d op stated as someone is making d ignorance people believe. if this post had been in science section, am sure it would have been dealt with. |
elpedro:Don't deceive urself. S.E is more complicated than u r meant to believe. u will run. infact u won't see S.E talk about things like this. |
GogobiriLalas:Calm down bros. S.E (schrodinger equation ) is real and in use even as we speak. but the truth is that the equation did not in anyway relate to what he was using t to prove I.e ops question. Schrodinger equation is far beyond this, more complicated Infact using t this way is like misusing it. |
JSoE:Anyone teaching u Schrodingers equation in first yr and expect u to understand t is insane. Infact it is insane to teach u S.E equation in first year. Am just trying to relate what the Person u quoted with S.E. the truth is that he is just using S.E to explain it. in reality we do not see S.E talk about things like what op said. simple and short. |
I must confess, Oron is a nice place. Good food, enough water, big fish, nice ladies etc |
Both! |
Nwogeh:Lol brother yea. let me P.M u |
princey83:Good to know. How far did you go into material science and Nuclear? Are you a physicist? or engineer? |
Teempakguy:So sorry sir, it's a name so pardon me. your take on the issue. do you think the government is making a nice move? |
L for Lalasticlala, S for Seun. What can you do with the thread? Lets give Nairalanders the opportunity to brainstorm and discuss the issue. The world and government are watching us. |
johnydon22:Also, i suggest that other private companies who feel they can generate enough power easily from solar and wind should do it and sell. I think there is a license given to private power companies. But Nuclear is what only government can sponsor |
johnydon22:Thinking so too. But even if we generate just 1000MW of electricity from Nuclear, it will help in developing the subject and increase research also. Governments are not ready to do anything on that solar and wind energy, so if they have chosen Nuclear, it just have to favour research. |
4. National Risk : Nuclear energy has given us the power to produce more weapons than to produce things that can make the world a better place to live in. We have to become more careful and responsible while using nuclear energy to avoid any sort of major accidents. They are hot targets for militants and terrorist organizations. Security is a major concern here. A little lax in security can prove to be lethal and brutal for humans and even for this planet. 5. Impact on Aquatic Life : Eutrophication is another result of radioactive wastes. There are many seminars and conferences being held every year to look for a specific solution. But there is no outcome as of now. Reports say that radioactive wastes take almost 10,000 years to get back to the original form. 6. Major Impact on Human Life : We all remember the disaster caused during the Second World War after the nuclear bombs were dropped over Hiroshima and Nagasaki. Even after five decades of the mishap, children are born with defects. This is primarily because of the nuclear effect. Do we have any remedy for this? The answer is still no. 7. Fuel Availability : Unlike fossil fuels which are available to most of the countries, uranium is very scarce resource and exist in only few of the countries. Permissions of several international authorities are required before someone can even thought of building a nuclear power plant. 8. Non Renewable : Nuclear energy uses uranium which is a scarce resource and is not found in many countries. Most of the countries rely on other countries for the constant supply of this fuel. It is mined and transported like any other metal. Supply will be available as long as it is there. Once all extracted, nuclear plants will not be of any use. Due to its hazardous effects and limited supply, it cannot be termed as renewable.

Disadvantages of Nuclear Energy 1. Radioactive Waste : The waste produced by nuclear reactors needs to be disposed off at a safe place since they are extremely hazardous and can leak radiations if not stored properly. Such kind of waste emits radiations from tens to hundreds of years. The storage of radioactive waste has been major bottleneck for the expansion of nuclear programs. The nuclear wastes contain radio isotopes with long half-lives. This means that the radio isotopes stay in the atmosphere in some form or the other. These reactive radicals make the sand or the water contaminated. It is known as mixed waste. The mixed wastes cause hazardous chemical reactions and leads to dangerous complications. The radioactive wastes are usually buried under sand and are known as vitrification. But these wastes can be used to make nuclear weapons. 2. Nuclear Accidents : While so many new technologies have been put in place to make sure that such disasters won’t happen again like the ones Chernobyl or more recently Fukushima but the risk associated with them are relatively high. Even small radiation leaks can cause devastating effects. Some of the symptoms include nausea, vomiting, diarrhea and fatigue. People who work at nuclear power plants and live near those areas are at high risk of facing nuclear radiations, if it happens. 3. Nuclear Radiation : There are power reactors called breeders. They produce plutonium. It is an element which is not found in the nature however it is a fissionable element. It is a by-product of the chain reaction and is very harmful if introduced in the nature. It is primarily used to produce nuclear weapons. Most likely, it is named as dirty bomb. http://www.conserve-energy-future.com/Disadvantages_NuclearEnergy.php

what's the state of Uranium mining in Nigeria?? The Nigeria Uranium Mining Company (NUMCO) was a parastatal organization that controlled the exploration and mining of uranium in Nigeria and was a public/private partnership with Total Compagnie Minière of France , which owned 40% of the company. In 1989, Total pulled out of the partnership, and in 1993 the government reassigned NUMCO's responsibilities to the Nigerian Geological Survey . The NUMCO corporation was dissolved in 1996, and the government is in the process of liquidating its remaining assets. [8] Recently, several important uranium deposits were discovered in Cross River State , Adamawa State , Taraba State , Plateau State , Bauchi State , and Kano State by the British Geological Survey . https://en.m.wikipedia.org/wiki/Mining_industry_of_Nigeria |
Lalasticlala, seun, Ujsizzle how do we support science and technology? let us give it the same media publicity we gave to Dino Melaye and Tinubu's wife saga. Or Laura Ikeji's Bo.obs and pregnancy is better than this?? |
Uranium in the Reactor Nuclear power stations and fossil-fuelled power stations of similar capacity have many features in common. Both require heat to produce steam to drive turbines and generators. In a nuclear power station, however, the fissioning of uranium atoms replaces the burning of coal or gas. In a nuclear reactor the uranium fuel is assembled in such a way that a controlled fission chain reaction can be achieved. The heat created by splitting the U-235 atoms is then used to make steam which spins a turbine to drive a generator, producing electricity. The chain reaction that takes place in the core of a nuclear reactor is controlled by rods which absorb neutrons and which can be inserted or withdrawn to set the reactor at the required power level. The fuel elements are surrounded by a substance called a moderator to slow the speed of the emitted neutrons and thus enable the chain reaction to continue. Water, graphite and heavy water are used as moderators in different types of reactors. Because of the kind of fuel used (ie the concentration of U-235, see below), if there is a major uncorrected malfunction in a reactor the fuel may overheat and melt, but it cannot explode like a bomb. A typical 1000 megawatt (MWe) reactor can provide enough electricity for a modern city of up to one million people.

How is Uranium mined? Uranium ore can be mined by underground or open-cut methods, depending on its depth. After mining, the ore is crushed and ground up. Then it is treated with acid to dissolve the uranium, which is recovered from solution. Uranium may also be mined by in situ leaching (ISL), where it is dissolved from a porous underground ore body in situ and pumped to the surface. The end product of the mining and milling stages, or of ISL, is uranium oxide concentrate (U O ). This is the form in which uranium is sold. Before it can be used in a reactor for electricity generation, however, it must undergo a series of processes to produce a useable fuel. For most of the world's reactors, the next step in making the fuel is to convert the uranium oxide into a gas, uranium hexafluoride (UF ), which enables it to be enriched. Enrichment increases the proportion of the uranium-235 isotope from its natural level of 0.7% to 4 - 5%. This enables greater technical efficiency in reactor design and operation, particularly in larger reactors, and allows the use of ordinary water as a moderator. After enrichment, the UF gas is converted to uranium dioxide (UO ) which is formed into fuel pellets. These fuel pellets are placed inside thin metal tubes which are assembled in bundles to become the fuel elements or assemblies for the core of the reactor. For reactors which use natural uranium as their fuel (and hence which require graphite or heavy water as a moderator) the U O concentrate simply needs to be refined and converted directly to uranium dioxide. When the uranium fuel has been in the reactor for about three years, the used fuel is removed, stored, and then either reprocessed or disposed of underground. |
who has and who mines Uranium? Uranium is widespread in many rocks, and even in seawater. However, like other metals, it is seldom sufficiently concentrated to be economically recoverable. Where it is, we speak of an orebody. In defining what is ore, assumptions are made about the cost of mining and the market price of the metal. Uranium reserves are therefore calculated as tonnes recoverable up to a certain cost. Australia's known resources are over 1.6 million tonnes of uranium recoverable at up to US$130/kg U (currently a bit above the market 'spot' price), Kazakhstan's are over 600,000 tonnes of uranium and Canada's and Russia's are over 450,000 tU. Australia's resources in this category are almost one third of the world's total, Kazakhstan's are 12%, Canada's and Russia's each 9%. Several countries have significant uranium resources. Apart from the top four, they are in order:Niger, South Africa, Brazil, Namibia, USA, China, Ukraine, Uzbekistan, Mongolia, and Jordan. Other countries have smaller deposits which could be mined if needed. Kazakhstan is the world's top uranium producer, followed by Canada and then Australia as the main suppliers of uranium to world markets - now over 68,000 tU per year. Uranium is sold only to countries which are signatories of the Nuclear Non-Proliferation Treaty (NPT), and which allow international inspection to verify that it is used only for peaceful purposes. |
Who uses Nuclear power About 12% of the world's electricity is generated from uranium in nuclear reactors. This amounts to over 2500 billion kWh each year, as much as from all sources of electricity worldwide in 1960. It comes from some 430 nuclear reactors with a total output capacity of about 375 000 megawatts (MWe) operating in 31 countries. Over 70 more reactors are under construction and another 170 are planned. Belgium, Bulgaria, Czech Republic, Finland, France, Hungary, Japan, South Korea, Slovakia, Slovenia, Sweden, Switzerland and Ukraine all get 30% or more of their electricity from nuclear reactors. The USA has 100 reactors operating, supplying 20% of its electricity. France gets three quarters of its electricity from uranium.
