These are K-Ar data obtained on glauconite, a potassium-bearing clay mineral that forms in some marine sediment. Woodmorappe fails to mention, however, that these data were obtained as part of a controlled experiment to test, on samples of known age, the applicability of the K-Ar method to glauconite and to illite, another clay mineral. He also neglects to mention that most of the 89 K-Ar ages reported in their study agree very well with the expected ages. Evernden and others 43 found that these clay minerals are extremely susceptible to argon loss when heated even slightly, such as occurs when sedimentary rocks are deeply buried. As a result, glauconite is used for dating only with extreme caution. The ages from the Coast Range batholith in Alaska Table 2 are referenced by Woodmorappe to a report by Lanphere and others Whereas Lanphere and his colleagues referred to these two K-Ar ages of and million years, the ages are actually from another report and were obtained from samples collected at two localities in Canada, not Alaska. There is nothing wrong with these ages; they are consistent with the known geologic relations and represent the crystallization ages of the Canadian samples. The Liberian example Table 2 is from a report by Dalrymple and others
Poor ratings at the Emmys were not a function of a pro-Trump backlash
Politics Analysis Analysis Interpretation of the news based on evidence, including data, as well as anticipating how events might unfold based on past events Poor ratings at the Emmys were not a function of a pro-Trump backlash By Philip Bump By Philip Bump September 20, Follow pbump Stephen Colbert covered a lot of territory as host of the Emmys, from President Trump’s TV viewing habits to a big swing at Bill Maher.
I was saddened to see how bad the ratings were on the Emmys last night — the worst ever. Trump realDonaldTrump September 20, Some quick fact-checking: The number of viewers on the Emmys broadcast was not the lowest ever, a title held by the show.
The three-month average SOI is —7 or lower.
Even those who are seeking relationships are not dating frequently. The survey found that dating in America is, indeed, affected by online matchmaking activity. But in analyzing our findings, we discovered another story: Large numbers of single Americans are not actively looking for relationships and even significant numbers of those looking for partners are not that active on the dating scene. At first glance, the survey results suggest ample targets for Cupid among American adults.
These data generally align with findings from a 50, household survey conducted by the U.
The Public and Private Sides of Ethnicity
Health Program Approximately 10 percent of all high school students report experiencing physical dating violence in the previous 12 months, and approximately 10 percent report experiencing sexual dating violence in the previous 12 months, according to the Centers for Disease Control and Prevention CDC. Unhealthy relationships during the teen years can disrupt normal development and contribute to other unhealthy behaviors in teens that can lead to problems over a lifetime.
Teens who experience dating violence are more likely to experience depression and anxiety, engage in unhealthy behaviors such as experimenting with tobacco, drugs and alcohol, and have thoughts about suicide, according to the CDC. The mental and physical health consequences can extend into adulthood, and unhealthy relationships in adolescence also can create a cycle of abusive relationships.
Prevention initiatives include early education about safe dating practices.
Rb and Sr are quite different elements and are incorporated into the various minerals in varying proportions according to the composition and structure of the minerals.
They were first passed in the s to prevent freed Black slaves from marrying Whites and the biracial children of White slave owners and African slaves from inheriting property. It was not until , during the height of the Civil Rights Movement, that the U. Supreme Court ruled in the Loving v. Virginia case that such laws were unconstitutional. At that time, 38 states in the U.
As suc, one could argue that it’s only been in recent years that interracial marriages have become common in American society. Of course, anti-miscegenation laws were part of a larger anti-Asian movement that eventually led to the Page Law of that effectively almost eliminated Chinese women from immigrating ot the U. These laws actually made the situation worse because Asian men were no longer able to bring their wives over to the U. So in a way, those who wanted to become married had no other choice but to socialize with non-Asians.
After World War II however, the gender dynamics of this interracial process flip-flopped. Further, after the passage of the Immigration Act , many of these Asian war brides eventually helped to expand the Asian American community by sponsoring their family and other relatives to immigrate to the U. These days, Asian Americans in interracial relationships are very common.
With “Mission 1” complete, Planet turns focus to data analysis
Ice-sheet dynamics Sampling the surface of Taku Glacier in Alaska. There is increasingly dense firn between surface snow and blue glacier ice. An ice core is a vertical column through a glacier, sampling the layers that formed through an annual cycle of snowfall and melt. At Summit Camp in Greenland, the depth is 77 m and the ice is years old; at Dome C in Antarctica the depth is 95 m and the age years.
The bubbles disappear and the ice becomes more transparent.
A curved mirror can create a similar image by reflection.
With the company’s constellation now able to image the Earth’s entire landmass once a day, Planet is shifting its attention to developing machine learning tools to analyze images and extract insights from them. Speaking at the NewSpace Europe conference here Nov. The bulk of that imagery, he says, comes from the more than operational Dove cubesats, developed in-house at Planet. The company also has five RapidEye medium-resolution satellites it acquired in , and 13 SkySat satellites from the acquisition of Terra Bella, formerly Skybox Imaging, from Google.
Six of those satellites launched Oct. That constellation, Shahid said, produces large volumes of data. Planet downlinks six terabytes of data per day, he said, with a total coverage area of million square kilometers. With the satellite constellation in place, the challenge for Planet now is to turn the volume of images it produces into data products. An example he gave was using images to count the number of cars in a lot.
The high-resolution images from SkySat images allow the algorithms to count individual cars. In medium-resolution, but more frequent, Dove images, the algorithms can instead measure the area of lots filled by cars, and from that estimate the number of cars.
5 facts about online dating
Littering Moochers In order for something to be universally loved or hated, it must stand the test of time. If we compare how much teenagers love puppies to how much somethings love puppies, we find the unsurprising result: Similarly, regardless of age, people agree that drain hair is just gross. But not everything is so consistently revered or despised.
The ionized iron lines are nearly black, whereas those produced by the much rarer elements yttrium Y , neodymium Nd , and lanthanum La are very weak.
Visual spectrum This site, closely coupled to The Natures of the Stars and The Hertzsprung- Russell HR Diagram , provides an introduction to the spectra of stars and allied celestial objects. Here we examine the principal way in which astronomers have learned so much about the stars. Spectra has been translated into Romanian. The visual spectrum Pass sunlight through a triangular prism or bounce it off the finely grooved surface of a compact audio disk and see it break merrily into a band of pure sparkling color, its “spectrum,” familiar in the colors of a rainbow, in light glittering from newly fallen snow, in the rings and haloes around a partly- clouded Sun and Moon, in the flash of a cut diamond, and in so many other facets of nature.
The classic colors red, orange, yellow, green, blue, and violet connect in a seemingly infinite number of shades, one blending smoothly into the next. Together they constitute the “visual spectrum” or “optical spectrum” because it is the part of the full spectrum that is seen with the human eye. The rainbow is a natural spectrum caused by the refraction and reflection of sunlight through raindrops, and shows that sunlight consists of a continuous run – – a continuum — of colors from red to violet.
Note the fainter outer bow caused by double reflections inside the raindrops. Kaler Extending the light: Most of the energy of the Universe is transported in this way, by radiation. The visual spectrum of light, however, is but a tiny portion of the whole picture, of a huge spectrum of radiation that extends in both directions from the edges of the rainbow.
If with superhuman eyes you could see beyond red, you would encounter the “infrared” — felt as heat on the skin — which would merge gradually into the familiar “radio” portion of the spectrum.
Online Dating & Relationships
Introduction Radiocarbon, or Carbon dating, was developed by W. It is perhaps one of the most widely used and best known absolute dating methods and has become an indispensable part of an archaeologist’s tool-kit. In , Libby was awarded the Nobel Prize in chemistry for radiocarbon dating.
The very small quantities typically found require at least g of ice to be used, limiting the ability of the technique to precisely assign an age to core depths.
It is updated fortnightly. Significant sub-surface warming has been observed in the western or central equatorial Pacific Ocean. One-third or more of surveyed climate models show sustained warming to at least 0.

We are constantly evaluating the utility of given probe sets and probe designs, in addition to expanding the number of UCE loci we are targeting. We have several larger probes sets in the works, and we are also working on optimizing probe sets based on their capture success, phylogenetic utility, etc. Please check back for updates.
These days, Asian Americans in interracial relationships are very common.
The chronology comprises alternating dates of peaks and troughs in economic activity. A recession is a period between a peak and a trough, and an expansion is a period between a trough and a peak. During a recession, a significant decline in economic activity spreads across the economy and can last from a few months to more than a year. Similarly, during an expansion, economic activity rises substantially, spreads across the economy, and usually lasts for several years.
In both recessions and expansions, brief reversals in economic activity may occur-a recession may include a short period of expansion followed by further decline; an expansion may include a short period of contraction followed by further growth. The Committee applies its judgment based on the above definitions of recessions and expansions and has no fixed rule to determine whether a contraction is only a short interruption of an expansion, or an expansion is only a short interruption of a contraction.
The most recent example of such a judgment that was less than obvious was in , when the Committee determined that the contraction that began in was not a continuation of the one that began in , but rather a separate full recession. The Committee does not have a fixed definition of economic activity. It examines and compares the behavior of various measures of broad activity: The Committee also may consider indicators that do not cover the entire economy, such as real sales and the Federal Reserve’s index of industrial production IP.
How Old is the Earth
By Aaron Smith and Monica Anderson Digital technology and smartphones in particular have transformed many aspects of our society, including how people seek out and establish romantic relationships. Here are five facts about online dating: When we first studied online dating habits in , most Americans had little exposure to online dating or to the people who used it, and they tended to view it as a subpar way of meeting people.
To install casing a shallow auger can be used to create a pilot hole, which is then reamed expanded until it is wide enough to accept the casing; a large diameter auger can also be used, avoiding the need for reaming.
By Aaron Smith and Maeve Duggan One in ten Americans have used an online dating site or mobile dating app themselves, and many people now know someone else who uses online dating or who has found a spouse or long-term partner via online dating. General public attitudes towards online dating have become much more positive in recent years, and social networking sites are now playing a prominent role when it comes to navigating and documenting romantic relationships.
Online dating is also relatively popular among the college-educated, as well as among urban and suburban residents. Attitudes towards online dating are becoming more positive over time Even today, online dating is not universally seen as a positive activity—a significant minority of the public views online dating skeptically. At the same time, public attitudes towards online dating have grown more positive in the last eight years: In general, online daters themselves give the experience high marks.
Yet even some online daters view the process itself and the individuals they encounter on these sites somewhat negatively. People in nearly every major demographic group—old and young, men and women, urbanites and rural dwellers—are more likely to know someone who uses online dating or met a long term partner through online dating than was the case eight years ago. And this is especially true for those at the upper end of the socio-economic spectrum: Negative experiences on online dating sites are relatively common Even as online daters have largely positive opinions of the process, many have had negative experiences using online dating.
Women are much more likely than men to have experienced uncomfortable contact via online dating sites or apps: One in five online daters have asked someone to help them review their profile.
