A indicates alpha decay; B indicates beta decay. We can calculate the half-lives of all of these elements. All the intermediate nuclides between U and Pb are highly unstable, with short half-lives. Then any excess of Pb must be the result of the decay of U When we know how much excess Pb there is, and we know the current quantity of U , we can calculate how long the U in our sample has been decaying, and therefore how long ago the rock formed. Th and U also give rise to radioactive series — different series from that of U , containing different nuclides and ending in different nuclides of lead. Chemists can apply similar techniques to all three, resulting in three different dates for the same rock sample.

Posted on May 26, by Admin mymitra An Oxford University study suggests that nearly one in three of us who use the internet have visited online dating sites. An international survey of 24, men and women who are presently online found that just six per cent had gone to dating websites in but by , 30 per cent of the sample had tried them with 15 per cent finding their current partner that way.
Middle-aged men and women aged looking to start new relationships after were the most likely to use online dating sites, with 36 per cent of them revealing that they had found their current partner online. The study dispels the myth that social networking and online dating is primarily for the young with just 23 per cent of year-olds saying they had started a relationship through the internet.
However, only two people in the sample started a relationship in their 70s and neither did this through the internet. The study reveals to what extent chat rooms and social network sites have played a role in introducing people to their partners. For people who began their relationship before , less than 10 per cent said they had met on a social networking site. But by that had doubled to 21 per cent, while the popularity of chat rooms declined over the same period.
The study reveals there might be national differences in attitudes to online dating. Users in Northern European countries are slightly but significantly more likely to rely on one-to-one dating websites while those in Spanish and Portuguese-speaking nations are more likely to use social networking sites as well. The most gregarious online nation appears to be Brazil — more than eight of out ten 83 per cent of those interviewed who had access to the internet said they had met someone who had been first introduced to them online, but this was not just limited to personal relationships.

Samuel Rhine had been educated in a Harrisburg business college, had taught school and later been a farmer and merchant. The family moved to Marshallville, Ohio , when Joseph was in his early teens.

All Events The paper “Aspirational pursuit of mates in online dating markets” has received widespread attention in the media and online. Out of your league? Study shows most online daters seek significantly more desirable mates even though the chances of getting a response are lower. Researchers at the University of Michigan and the Santa Fe Institute showed that leagues do emerge in online dating networks, in the form of a hierarchy of desirability. The researchers applied the algorithm to anonymized data from users of a dating website in four major U.
New York, Boston, Chicago, and Seattle. The study is the first large-scale analysis to focus on hierarchies of desirability in online dating data. Among other things, it reveals how people behave strategically during online courtship by altering the length and number of messages they send to individuals at different levels of desirability. Of the four cities analyzed, the notable exception was the Seattle, where the researchers did observe a payoff for writing longer messages.
When the researchers compared desirability scores against user attributes, they found correlations between age, education level, and ethnicity. Though the study affirms that many people are making choices that align with popular stereotypes, Bruch stresses that this is not a rule that holds for all individuals.

Get The Discount Getting started with your own abstract example Now that we know that all good examples of abstracts are, in fact, a precise but brief summary of your whole paper, it becomes pretty obvious that you cannot start working on an abstract until the paper is written – not unless you have a very detailed outline you plan to stick to in your work. Here are some other formatting tips for all abstract examples that may prove handy in the process: Use the same font and spacing: However, official APA guidelines are not that strict – as long as the font is plain and easy to read, you can use any other analog.
More is not always better: While some educational establishments allow it, you should still try to stay within a single-page limit. Don’t forget the keywords: You can include up to two lines of those. But remember that any example of an abstract will have an indented line with keywords, so try to highlight about terms, no more. Now that you know all the theory you need to know, let’s take a look at more practical examples of abstract below.

Building evidence into education I think there is a huge prize waiting to be claimed by teachers. By collecting better evidence about what works best, and establishing a culture where this evidence is used as a matter of routine, we can improve outcomes for children, and increase professional independence. This is not an unusual idea. Outcomes for patients have improved as a result, through thousands of tiny steps forward. A change of culture was also required, with more education about evidence for medics, and whole new systems to run trials as a matter of routine, to identify questions that matter to practitioners, to gather evidence on what works best, and then, crucially, to get it read, understood, and put into practice.
I want to persuade you that this revolution could — and should — happen in education.

November 19, iStock. He has taught driving courses for 47 years. And one of the best pieces of advice he can give has absolutely nothing to do with an automobile. Other road hazards like fog, deer, and road-hogging commercial trucks never seem to take a break. For some practical advice on what to do in these situations, we asked Solomon to break down 10 common driving obstacles and the best ways to cope with them. If your car goes into a skid or loses traction, the best thing to do is remove your foot off the accelerator.
If you have standard braking, keep your foot entirely off the brake. If you have an automatic braking system ABS , which is pretty much standard in most newer cars, you want to push the pedal down and wait for the car to regain traction. The ABS can pulsate the brakes faster than your foot can. You also want to turn the wheel in the direction you want the front of the car to go. A little foresight is best here.
Solomon advises you keep a shovel, brush, and a pair of traction mats in your trunk. Kitty litter may also work for traction, but the mats are reusable. Clear the snow away from the wheels and try moving forward or in reverse.
