BPC in Lintong , China , Radio-controlled clocks receive their time calibration signals with built-in long-wave receivers. They use long-wave, rather than short-wave or medium-wave , because long-wave signals from the transmitter to the receiver always travel along the same direct path across the surface of the Earth , so the time delay correction for the signal travel time from the transmitting station to the receiver is always the same for any one receiving location. Longwaves travel by groundwaves that hug the surface of the earth, unlike mediumwaves and shortwaves. These different propagation paths can make the time lag different for every signal received. The delay between when the long-wave signal was sent from the transmitter when the coded time was correct and when the signal is received by the clock when the coded time is slightly late depends on the overland distance between the clock and the transmitter and the speed of light through the air , which is also very nearly constant. Since the time lag is essentially the same, a single constant shift forward from the time coded in the signal can compensate for all long-wave signals received at any one location from the same time signal station. Historic[ edit ] Swedish station SAQ, located at the Varberg Radio Station facility in Grimeton, is the last remaining operational Alexanderson alternator long-wave transmitter.
Most accept the view that “a civilization is a culture which has attained a degree of complexity usually characterized by urban life. Other characteristics usually present in a civilization include a system of writing to keep records, monumental architecture in place of simple buildings, and an art that is no longer merely decorative, like that on Neolithic pottery, but representative of people and their activities.
All these characteristics of civilization first appeared in Mesopotamia.

All patients received N2O and many received fentanyl, midazolam, bupivacaine, or lidocaine. Anesthesia was induced with midazolam 0. Both isoflurane and Sevoflurane were administered at loss of consciousness in doses of 1. The average MAC dose was 0. There were no significant differences in hemodynamics, cardioactive drug use, or ischemia incidence between the two groups. Outcome was also equivalent. In this small multicenter study, Sevoflurane appears to be as effective and as safe as isoflurane for supplementation of opioid anesthesia for coronary bypass grafting.
Non-Cardiac Surgery Patients at Risk for Myocardial Ischemia Sevoflurane-N2O was compared to isoflurane-N2O for maintenance of anesthesia in a multicenter study in patients, age 40 to 87 years who were at mild-to-moderate risk for myocardial ischemia and were undergoing elective non-cardiac surgery. The average duration of surgery was less than 2 hours.
There was no significant difference between the anesthetic regimens for intraoperative hemodynamics, cardioactive drug use, or ischemic incidents, although only 83 patients in the Sevoflurane group and 85 patients in the isoflurane group were successfully monitored for ischemia. The outcome was also equivalent in terms of adverse events, death, and postoperative myocardial infarction.

A heat wave is a period of excessively hot weather, which may be accompanied by high humidity, especially in oceanic climate countries. While definitions vary, a heat wave is usually measured relative to the usual weather in the area and relative to normal temperatures for the season. Temperatures that people from a hotter climate consider normal can be termed a heat wave in a cooler area if.
In February , scientists revised the estimate of the magnitude to 9. A study estimated a magnitude of Mw 9. This quickly elevated the height and increased the speed of waves, destroying the nearby Indonesian town of Lhoknga. The Sumatra earthquake is believed to have been a foreshock , preceding the main event by over two years. Their seismic moments can account for a significant fraction of the global seismic moment across century-scale time periods.
Of all the moment released by earthquakes in the years from through , roughly one-eighth was due to the Indian Ocean earthquake. This quake, together with the Good Friday earthquake Alaska , and the Great Chilean earthquake , account for almost half of the total moment. Since , the only earthquakes recorded with a greater magnitude were the Great Chilean earthquake Magnitude 9.
It’s pictures like mine that had a high school version of me spending all of her allowance on Metabolife because if the girl in the magazine could do it, then surely I could, too. And I knew back then that everything in my life would be better, easier, perfect even I knew this because that’s what I was told, not by my doctor because he was old and who needed to listen to him? I knew it because Courtney Cox went from being a lonely, dateless loser who breaks porch swings and didn’t have a prom date to a svelte and sexy crop top-wearing serial man-eater on Friends.
I knew it because even though she was one of my favorite actresses, Sarah Rue didn’t get the cover of any magazines until she dropped five dress sizes. I knew it because books like Jemima J by Jane Green told me in their shiny chick-lit packaging that even if he notices how smart you are, even if he laughs at your jokes, even if he tells you that you have “such a pretty face,” he won’t admit he wants you until you lose your fat ass.
In physics, optically stimulated luminescence (OSL) is a method for measuring doses from ionizing is used in at least two applications: luminescence dating of ancient materials: mainly geological sediments and sometimes fired pottery, bricks etc., although in the latter case thermoluminescence dating is used more often; radiation dosimetry, which is the measurement of .
History of Technology Heroes and Villains – A little light reading Here you will find a brief history of technology. Initially inspired by the development of batteries, it covers technology in general and includes some interesting little known, or long forgotten, facts as well as a few myths about the development of technology, the science behind it, the context in which it occurred and the deeds of the many personalities, eccentrics and charlatans involved.
You may find the Search Engine , the Technology Timeline or the Hall of Fame quicker if you are looking for something or somebody in particular. Scroll down and see what treasures you can discover. Background We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind. Volta’s pile was at first a technical curiosity but this new electrochemical phenomenon very quickly opened the door to new branches of both physics and chemistry and a myriad of discoveries, inventions and applications.
The electronics, computers and communications industries, power engineering and much of the chemical industry of today were founded on discoveries made possible by the battery. Pioneers It is often overlooked that throughout the nineteenth century, most of the electrical experimenters, inventors and engineers who made these advances possible had to make their own batteries before they could start their investigations.
They did not have the benefit of cheap, off the shelf, mass produced batteries.
One of these terrifying events occurred in Italy back in , just 62 miles kilometers north of Venice. In the early s, other researchers started publishing evidence that the Cape Verdes could generate large tsunamis. Others have argued that Spain’s Canary Islands have already done so. Simon Day, a senior researcher at University College London has sparked repeated controversy by warning that any future eruption of the Canary Islands’ active Cumbre Vieja volcano could set off a flank collapse that might form an initial wave 3, feet high.
Such a wave might still be feet high when it reached west Africa an hour or so later he says, and would still be feet high along the coasts of North and South America. So far, such studies have raised mainly tsunamis of publicity, and vigorous objections from other scientists that such events are improbable.

Within each section, the nominated books are listed in order of their publication date. Although the most recently published books obviously merit the most attention, the earlier published books still retain sufficient importance for inclusion in the listing. Every effort was made to list the most updated and revised editions of earlier published books. In the absence of consensus on the Romanization of Arabic names, the spelling of group names such as al Qaida have been left as published in their original title e.
Readers are encouraged to nominate additional topics and books for inclusion in future lists. The following volumes provide excellent information and analysis about virtually all aspects of terrorism and counterterrorism: James Ciment, editor, World Terrorism: It includes more than in-depth articles providing background information and analysis on the spectrum of categories and types of terrorist groups ranging from domestic to international, religious and nationalist, state and non-state supported, left-wing and right-wing, as well as entries on worldwide terrorist incidents.
The appendix includes hundreds of photographs, maps, and diagrams.
While most of us probably think of molasses as a tasty ingredient in treats like gingerbread, the sticky stuff has quite a few other uses. The steel tank was enormous: By Unknown – Anthony Mitchell Sammarco. Arcadia Publishing, , Public Domain, Wikimedia Commons The massive tank was nearly full on January 15, thanks to a recent infusion of 2. Just after noon, something went horribly wrong.
Although some readers might miss it, I think those who read the blog very closely will notice that this British woman was dating a Chinese man only as a project in connection with writing a general column about interracial dating. She was just dating this man as one of many other tasks to write about her experiences. My only guess is that she has also dated men of many other ethnicities, including non-Asians such as African-Americans and Latinos. I do oppose her post, or at least the implications from it, or how she characterized the date.
Her use of sarcasm was mean-spirited. That said, you have to be fair and realize that if her description of the date is accurate, the man was unworthy. At some point, you have to put your foot down, and even if she is the foreigner in another land, if this man truly wanted to get to know her better, that means respecting her cultural norms and she must respect his. He ought to take charge.
Artificial reefs[ edit ] The value of good surf in attracting surf tourism has prompted the construction of artificial reefs and sand bars. Artificial surfing reefs can be built with durable sandbags or concrete, and resemble a submerged breakwater. These artificial reefs not only provide a surfing location, but also dissipate wave energy and shelter the coastline from erosion. Ships such as Seli 1 that have accidentally stranded on sandy bottoms, can create sandbanks that give rise to good waves.
However, the reef failed to produce any quality waves and was removed in In Kovalam , South West India, an artificial reef has, however, successfully provided the local community with a quality lefthander, stabilized coastal soil erosion, and provided good habitat for marine life.

Messenger Women have struggled for greater participation in spheres reserved for men in every nation, dating back at least to BCE. This explains the impulse for feminism. For some, feminism is a theory or ideology about unequal and oppressive gender relations. For most feminists, however, feminism is a political practice — a desire to change the world. The term quickly spread to every continent, in some colonised countries linked with struggle for freedom from the European colonial yoke.
Suffragette Emmeline Pankhurst addresses crowd in New York, Workers had to be freed from exploitation of their labour by the owners of big business, and wives had to be freed from exploitation of their unpaid domestic labour by husbands. Living in the post-feminist era? This is variously explained as a time when feminism is no longer needed, a time when feminism is no longer active, or a time when feminism has been killed by the conservative neoliberal backlash.
But it will be a long time coming. Furthermore, there is evidence of retreat.
Order Reprint of this Story August 24, From Jacksonville to Miami, five Democrats and two Republicans are putting thousands of miles on their campaign coaches this weekend, scouring the state in search of the undecided. Perhaps more than half of the total ballots in the primary election already have been cast, but every vote matters in the scrum for political survival. On the right, Trump-endorsed Congressman Ron DeSantis is expected to prevail over Agriculture Commissioner Adam Putnam, but a dicey week for the president could add a hint of doubt for the front-runner.

Hyperthermia , also known as heat stroke, becomes commonplace during periods of sustained high temperature and humidity. Older adults, very young children, and those who are sick or overweight are at a higher risk for heat-related illness. The chronically ill and elderly are often taking prescription medications e. When combined with peripheral vasodilation and venous stasis , the excess fluid accumulates in the dependent areas of the extremities.
The heat edema usually resolves within several days after the patient becomes acclimated to the warmer environment. No treatment is required, although wearing support stockings and elevating the affected legs will help minimize the edema. Heat rash , also known as prickly heat, is a maculopapular rash accompanied by acute inflammation and blocked sweat ducts.
The sweat ducts may become dilated and may eventually rupture, producing small pruritic vesicles on an erythematous base. Heat rash affects areas of the body covered by tight clothing. If this continues for a duration of time it can lead to the development of chronic dermatitis or a secondary bacterial infection. Prevention is the best therapy. It is also advised to wear loose-fitting clothing in the heat.
