Outcomes begin to diverge in grade school and keep on diverging into adolescence as children spend more time outside the house. Infants and toddlers who develop cancer fare about the same no matter where they live, the study data showed. The tie between neighborhood and outcome increases with age. Their findings were published in Cancer Nursing.Ĭorrelation between neighborhoods and complications doesn’t prove neighborhoods cause complications, but the hypothesis was bolstered by a second observation. Researchers combined health and location data and found that the neighborhoods where children live had a bigger impact on outcomes than race and ethnicity alone.

However, most food lovers like to enjoy potica made with walnuts, tarragon (‘pehtran’), or poppy seeds. Potica may not always be sweet as you can come across savoury versions too, such as those filled with pork cracknels.

Potato ‘žganci’ are typical of Prekmurje and Pohorje in the northeast of Slovenia, while buckwheat ‘žganci’-made from buckwheat flour, water, salt, and oil-are common in Gorenjska (northwest Slovenia). Žganci is a simple Slovenian dish that also varies according to region. In other areas, you can have ‘jota’ with other local vegetables, and sometimes even barley. You’ll find ‘jota’ wherever you go in Slovenia, but the dish varies according to region.įor example, in Istria (southwest Slovenia) the stew contains sour cabbage (‘kislo zelje’) rather than turnip, and doesn’t include potatoes.

You can either have them as a side dish to accompany rich meats like venison (these are usually the standard curd cheese ones), or as a dessert with a topping of breadcrumbs and honey. ‘Štruklji’ are the roulade-shaped dumplings that come in many varieties, from baked or boiled to savoury or sweet. While there, you’ll most definitely be given some Teran, the region’s most prized red wine that goes deliciously well with ‘Kraški pršut’. We recommend you enjoy its excellent flavour and texture by eating it at its very source, at one of the many farms in Slovenia’s Karst region. ‘Kraški pršut’ (Karst cured ham or prosciutto) is Slovenia’s top-quality dry cured ham that also boasts the seal of Protected Geographical Indication. Here’s another very famous Slovenian food. You’ll find Kranjska sausage mainly in the Alpine region of Gorenjska (Upper Carniola). And secondly, to conform with its PGI standard, it must always consist of the exact amounts of pork (68%), beef (12%), and bacon (20%). Where does this famous sausage get its delightful and unique taste? For starters, it’s smoked. AND it’s also the first sausage to have entered space!

A newer method of radioactive tracing involves the use of a new clock, based on the radioactive decay of 235uranium to 231protactinium. ![]() Using the cyclotron, carbon –14 dating could be used for objects as old as 100,000 years, while samples containing radioactive beryllium could be dated as far back as 10 –30 million years. They also improved the equipment used to detect these elements, and in 1939, scientists first used a cyclotron particle accelerator as a mass spectrometer. They developed the uranium-thorium method, the potassium-argon method, and the rubidium-strontium method, all of which are based on the transformation of one element into another. Starting where Boltwood and Libby left off, scientists began to search for other long-lived isotopes. Still, even with the help of laboratories worldwide, radiocarbon dating was only accurate up to 70,000 years old, since objects older than this contained far too little carbon –14 for the equipment to detect. Using the carbon –14 method, scientists determined the ages of artifacts from many ancient civilizations. Libby's method, called radiocarbon or carbon –14 dating, gave new impetus to the science of radioactive dating. ![]() He continued his research and, through improvements in his equipment and procedures, was eventually able to determine the age of an object up to 50,000 years old with a precision of plus-or-minus 10%. He found that his methods, while not as accurate as he had hoped, were fairly reliable. Libby began testing his carbon –14 dating procedure by dating objects whose ages were already known, such as samples from Egyptian tombs. ![]() The length of time required for one-half of the unstable carbon –14 nuclei to decay (i.e., the half-life ) is 5,730 years. The difference between the concentration of carbon –14 in the material to be dated and the concentration in the atmosphere provides a basis for estimating the age of a specimen, given that the rate of decay of carbon –14 is well known. Whatever carbon –14 was present at the time of the organism's death begins to decay to nitrogen –14 by emitting radiation in a process known as beta decay. This carbon –14 cycles through an organism while it is alive, but once it dies, the organism accumulates no additional carbon –14. In any living organism, the relative concentration of carbon –14 is the same as it is in the atmosphere because of the interchange of this isotope between the organism and the air. Among the less abundant isotopes is carbon –14, which is produced in small quantities in the earth's atmosphere through interactions involving cosmic rays. Together carbon –12 and carbon –13 make up 99% of all naturally occurring carbon. The most abundant isotope in nature is carbon –12, followed in abundance by carbon –13. Carbon has isotopes with atomic weights between 9 and 15. He became intrigued by carbon –14, a radioactive isotope of carbon. The first method for dating organic objects (such as the remains of plants and animals) was developed by another American chemist, Willard Libby (1908 –1980). While the uranium-lead dating method was limited (being only applicable to samples containing uranium), it was proved to scientists that radioactive dating was both possible and reliable. Boltwood used this method, called radioactive dating, to obtain a very accurate measurement of the age of Earth. Thus, the greater the amount of lead, the older the rock. This was because uranium, as it underwent radioactive decay, would transmute into lead over a long span of time. In 1907, the American chemist Bertram Boltwood (1870 –1927) proposed that rocks containing radioactive uranium could be dated by measuring the amount of lead in the sample. However, many objects were found in caves, frozen in ice, or in other areas whose ages were not known in these cases, it was clear that a method for dating the actual object was necessary. By comparing the placement of objects with the age of the rock and silt layers in which they were found, scientists could usually make a general estimate of their age. It is based on the decay rate of the radioactive carbon isotope 14C, a form of carbon taken in by all living organisms while they are alive.īefore the twentieth century, determining the age of ancient fossils or artifacts was considered the job of paleontologists or paleontologists, not nuclear physicists. Carbon dating is a technique used to determine the approximate age of once-living materials. ![]() |
