Studying oyster fossils can help paleontologists discover how long the oyster lived, and in what conditions. If the oyster struggled for survival, the rings would be thinner. Some fossils show how an organism lived. At times, the sticky resin has dripped down a tree trunk, trapping air bubbles, as well as small insects and some organisms as large as frogs and lizards. Amber can preserve tissue as delicate as dragonfly wings. Some ants were trapped in amber while eating leaves, allowing scientists to know exactly what they ate, and how they ate it.
SFU Search. So you applied for a co-op, internship or full-time position and the organization wants to schedule a pre-screen interview with you. Are you scratching your head and wondering what a pre-screen interview is and how you can prepare for it? Pre-screen interviews are usually conducted by the organization’s Human Resources HR representatives or recruiters to narrow down applicants in the candidate selection process, saving the hiring managers time while learning more about the qualified candidates prior to the actual in-person interview.
Here are some quick and useful tips to help you prepare for pre-screen interviews to increase your chance at moving on to the next round of the selection process! Pre-screen interviews are usually conducted over the phone and often last about 20 to 30 minutes.

Background: The timing of sexual intercourse in relation to ovulation strongly influences the chance of conception, although the actual number of fertile days in a woman’s menstrual cycle is uncertain. The timing of intercourse may also be associated with the sex of the baby. Methods: We recruited healthy women who were planning to become pregnant.
At the same time the women stopped using birth-control methods, they began collecting daily urine specimens and keeping daily records of whether they had sexual intercourse. We measured estrogen and progesterone metabolites in urine to estimate the day of ovulation. Results: In a total of menstrual cycles for which the dates of ovulation could be estimated, pregnancies were initiated, as indicated by increases in the urinary concentration of human chorionic gonadotropin around the expected time of implantation.
Conception occurred only when intercourse took place during a six-day period that ended on the estimated day of ovulation. The probability of conception ranged from 0. There was no evident relation between the age of sperm and the viability of the conceptus, although only 6 percent of the pregnancies could be firmly attributed to sperm that were three or more days old.
Cycles producing male and female babies had similar patterns of intercourse in relation to ovulation. Conclusions: Among healthy women trying to conceive, nearly all pregnancies can be attributed to intercourse during a six-day period ending on the day of ovulation. For practical purposes, the timing of sexual intercourse in relation to ovulation has no influence on the sex of the baby. Abstract Background: The timing of sexual intercourse in relation to ovulation strongly influences the chance of conception, although the actual number of fertile days in a woman’s menstrual cycle is uncertain.
Substances Chorionic Gonadotropin.

Radiocarbon dating also referred to as carbon dating or carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon , a radioactive isotope of carbon. The method was developed in the late s at the University of Chicago by Willard Libby , who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen.

Reis studies social interactions and the factors that influence the quantity and closeness of our relationships. He coauthored a review article that analyzed how psychology can explain some of the online dating dynamics. You may have read a short profile or you may have had fairly extensive conversations via text or email. Her research currently focuses on online dating, including a study that found that age was the only reliable predictor of what made online daters more likely to actually meet up.
Where online dating differs from methods that go farther back are the layers of anonymity involved. If you meet someone via a friend or family member, just having that third-party connection is a way of helping validate certain characteristics about someone physical appearance, values, personality traits, and so on. Do you make one another laugh? Study after psychological study support that those types of principles are important in relationships , and are predictors of relationship success, he notes.
Online dating is a way to open doors to meet and date people, Reis says. And one thing the apps and sites have going for them is that ability to simply help you meet more people. Sameer Chaudhry, MD, an internist at the University of North Texas in Dallas, coauthored a BMJ Evidence-Based Medicine paper for which he and his coauthor considered nearly 4, studies across psychology, sociology, neurocognitive science, and other disciplines to come up with a series of guidelines for how to set up a profile, how to select matches, and how to approach online interactions.

There are nearly 4 million babies born in the United States each year. While most babies are born healthy, some infants are born with serious but treatable medical conditions. These conditions can be present in any family, even those without a family history of them. Newborn screening helps health professionals to identify and treat these conditions before they make a baby sick. First, a physician , nurse, midwife , or other trained member of the hospital staff will fill out a newborn screening card.
Parents are welcome to be a part of this process by holding their baby while the heel stick is performed.
Only pre-implantation genetic diagnosis (PGD) has been approved as a technique which does this. So you can’t medically intervene with conception just to.
This section looks at the process of selecting candidates. A variety of methods are available and consideration needs to be given as to which are suitable for a particular role. These include: Application forms and CVs, Online screening and shortlisting, Interviews, Psychometric testing, Ability and aptitude tests, Personality profiling, Presentations, Group exercises, Assessment centres and References. The traditional approach to applying for jobs is to complete a fairly lengthy application form online or hard copy.
This may be off-putting for some candidates. Therefore, application forms, if used, should only address the really important areas to allow shortlisting to take place.

Radiocarbon dating is one of the most widely used scientific dating methods in archaeology and environmental science. It can be applied to most organic materials and spans dates from a few hundred years ago right back to about 50, years ago – about when modern humans were first entering Europe. For radiocarbon dating to be possible, the material must once have been part of a living organism. This means that things like stone, metal and pottery cannot usually be directly dated by this means unless there is some organic material embedded or left as a residue.
As explained below, the radiocarbon date tells us when the organism was alive not when the material was used. This fact should always be remembered when using radiocarbon dates. The dating process is always designed to try to extract the carbon from a sample which is most representative of the original organism. In general it is always better to date a properly identified single entity such as a cereal grain or an identified bone rather than a mixture of unidentified organic remains.
The radiocarbon formed in the upper atmosphere is mostly in the form of carbon dioxide. This is taken up by plants through photosynthesis. Because the carbon present in a plant comes from the atmosphere in this way, the ratio of radiocarbon to stable carbon in the plant is virtually the same as that in the atmosphere. Plant eating animals herbivores and omnivores get their carbon by eating plants. All animals in the food chain, including carnivores, get their carbon indirectly from plant material, even if it is by eating animals which themselves eat plants.
The net effect of this is that all living organisms have the same radiocarbon to stable carbon ratio as the atmosphere.
How Pre-Selection With Women Works to Get You Laid

Fossils tell us when organisms lived, as well as provide evidence for the progression and evolution of life on earth over millions of years. Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils range in age from 10, to 3. The observation that certain fossils were associated with certain rock strata led 19th century geologists to recognize a geological timescale.
Like extant organisms, fossils vary in size from microscopic, like single-celled bacteria, to gigantic, like dinosaurs and trees. Permineralization is a process of fossilization that occurs when an organism is buried. The empty spaces within an organism spaces filled with liquid or gas during life become filled with mineral-rich groundwater. Minerals precipitate from the groundwater, occupying the empty spaces. This process can occur in very small spaces, such as within the cell wall of a plant cell.
Small-scale permineralization can produce very detailed fossils. For permineralization to occur, the organism must be covered by sediment soon after death, or soon after the initial decay process. The degree to which the remains are decayed when covered determines the later details of the fossil. Fossils usually consist of the portion of the organisms that was partially mineralized during life, such as the bones and teeth of vertebrates or the chitinous or calcareous exoskeletons of invertebrates.
However, other fossils contain traces of skin, feathers or even soft tissues.
