Dating heat

Nina Dobrev Bikini Photos Heat Up Ibiza, Spark More Dating Rumors



Before jet-setting to L. A. for the 2014 MTV Video Music Awards, Nina Dobrev spent Friday afternoon in the sun on a luxurious yacht off the coast of Ibiza, Spain.



Needless to say, she looks pretty darn good in a bikini.



Wearing a black two-piece, the 25-year-old star of The Vampire Diaries was smiling and letting her hair down as she jumped into the ocean with her friends.



Among them? The Hunger Games' Alexander Ludwig. Cue the dating rumors. though Dobrev has so many boyfriends as it is, he'd better get in line.



In all seriousness, the signs point to a friendship, nothing more. Although we know Dobrev is well prepared to handle any dating stories that exist online.



After romance rumors were started with Orlando Bloom, Benjamin McKenzie, and others, the brunette beauty took to Twitter to set the record straight.



"Apparently I have SOOOO many boyfriends. Here's four more," she Tweeted with a picture of The Vampire Diaries and The Originals cast members.



Yeah, the celebrity gossip sites can get a little carried away with the dating rumors, we know. Point well taken, and very well played by the actress.



But when you're this gorgeous, hitting up A-list events and seemingly "friends" with every hunk from Ibiza to L. A. can you blame us. Just saying.



Absolute dating



Absolute dating is the process of determining an approximate computed age in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty and precision. [ 1 ] [ 2 ] Absolute dating provides a computed numerical age in contrast with relative dating which provides only an order of events.



In archeology, absolute dating is usually based on the physical or chemical properties of the materials of artifacts, buildings, or other items that have been modified by humans. Absolute dates do not necessarily tell us precisely when a particular cultural event happened, but when taken as part of the overall archaeological record they are invaluable in constructing a more specific sequence of events.

Radiometric techniques [ edit ]



Radiocarbon dating [ edit ]



One of the most widely used and well-known absolute dating techniques is carbon-14 (or radiocarbon ) dating, which is used to date organic remains. This is a radiometric technique since it is based on radioactive decay. Cosmic radiation entering the earth’s atmosphere produces carbon-14, and plants take in carbon-14 as they fix carbon dioxide. Carbon-14 moves up the food chain as animals eat plants and as predators eat other animals. With death, the uptake of carbon-14 stops. It takes 5,730 years for half the carbon-14 to change to nitrogen; this is the half-life of carbon-14. After another 5,730 years only one-quarter of the original carbon-14 will remain. After yet another 5,730 years only one-eighth will be left. By measuring the carbon-14 in organic material. scientists can determine the date of death of the organic matter in an artifact or ecofact .



The relatively short half-life of carbon-14, 5730 years, makes the reliable only up to about 75,000 years. The technique often cannot pinpoint the date of an archeological site better than historic records, but is highly effective for precise dates when calibrated with other dating techniques such as tree-ring dating .



An additional problem with carbon-14 dates from archeological sites is known as the "old wood" problem. It is possible, particularly in dry, desert climates, for organic materials such as from dead trees to remain in their natural state for hundreds of years before people use them as firewood or building materials, after which they become part of the archaeological record. Thus dating that particular tree does not necessarily indicate when the fire burned or the structure was built. For this reason, many archaeologists prefer to use samples from short-lived plants for radiocarbon dating. The development of accelerator mass spectrometry (AMS) dating, which allows a date to be obtained from a very small sample, has been very useful in this regard.



Potassium-argon dating [ edit ]



Other radiometric dating techniques are available for earlier periods. One of the most widely used is potassium-argon dating (K-Ar dating). Potassium-40 is a radioactive isotope of potassium that decays into argon-40. The half-life of potassium-40 is 1.3 billion years, far longer than that of carbon-14, allowing much older samples to be dated. Potassium is common in rocks and minerals, allowing many samples of geochronological or archeological interest to be dated. Argon. a noble gas, is not commonly incorporated into such samples except when produced in situ through radioactive decay. The date measured reveals the last time that the object was heated past the closure temperature at which the trapped argon can escape the lattice. K-Ar dating was used to calibrate the geomagnetic polarity time scale .



Romance Reminders: Simple Ways to Turn up the Heat



When it comes to dating, here’s one thing you can count on: Everyone is looking for a romantic relationship that sizzles. No one actually prefers lukewarm leftovers to a fresh, hot gourmet meal. So why do so many relationships quickly begin to feel like they spend most of the time in the refrigerator wrapped in tin foil?



The answer lies in a bit of folk wisdom your grandmother told you when you were young: In any endeavor, you get out what you put in. Small effort yields small results. Too many singles expect chemistry alone to keep their relationships simmering. The truth is, you’ve got to fan the flames once in a while. Here are very simple yet surefire ways to send up some sparks.



1. Love Letters . In the 1989 film “Dead Poet’s Society,” Robin Williams plays an idealistic English teacher at a traditional boys’ prep school in New England. Nudging his students to think for themselves, he asks, “Language was developed for one endeavor—and that is…Mr. Perry?” “To communicate?” the hapless boy replies. “No!” the teacher responds. “To woo women!” Or to entice a man, for that matter. Want to light a fire under your romance? Put down your electronic gadgets for a few minutes, and get out a real piece of paper and a real pen. Handwrite a heartfelt letter to your partner. You don’t have to craft a Shakespearean sonnet—just say what’s on your heart. Then put the letter in a nice envelope and send it off. These days, receiving a personalized, handwritten letter in the mail is such a novelty, it’s sure to make an impression.



2. Quality Time (a. k.a Long Walks Together) . Walking side by side, with no particular destination, is a kind of moving romantic meditation. The easy rhythm of walking settles our thoughts and feelings, and encourages openness. Typical dating distractions are absent on a long walk—traffic jams, loud music, the clatter of noisy restaurants. The purpose of dating is not to see how much frenetic activity you can pack into your time together. The real purpose is to focus your full attention on each other, sharing who you are and what you want in life and in a life partner. Every step you take can bring you closer to each other and to the romance you desire.



3. Homemade Dinners . Generating romantic heat with food you prepare yourself is becoming a lost art. An abundance of other options—supermarkets filled with readymade dinners, takeout restaurants on every corner—has given convenience the upper hand. But there is something subtly seductive about sitting down to a meal made especially with love in mind. It is a romantic offering of time, effort, and creativity that can kindle the fire of attraction like nothing else. To turn up the heat, get in the kitchen.



4. Imaginative Gift Giving . To qualify as “imaginative,” the gift must be unique and meaningful, as if it could only have been properly given to one person. It must help you say, “I truly see you—and I like what I see.” Such a gift requires attentiveness and observation and the effort to get it right. It’s not just a CD; it is a compilation of songs you made yourself. Not just any book; it is the latest by her favorite author. Notice his beloved bag of Kona coffee is almost finished? Leave a new one for him in the kitchen. If you see her favorite bottle of perfume is almost empty; go grab her a refill.



Romantic heat doesn’t happen by itself—it takes intentionality. Be the one to strike a match, and watch as the temperature rises.

What is Heat Stroke?



The CDC reports that heat stroke is the most serious heat-related illness.



Heat stroke occurs when the body is exposed to an excessive amount of heat and becomes unable dissipate the heat through sweating.



When heat stroke happens, the body’s temperature rises rapidly, the body loses its ability to sweat, and it is unable to cool down.



Body temperature can rise to 106°F or higher within 10 to 15 minutes, and at 106°F brain death begins.



If emergency treatment is not provided, heat stroke can cause death or permanent disability in humans and animals.
