 the US is significant economy. And I think this is the beginning of a new chapter for a search for a global single currency or a basket of different currencies where the global currency is independent from national sovereignty.
SIMON LAUDER: In other words investors will start taking their money out of the US and looking for somewhere else to park it?
FARIBORZ MOSHIRIAN: That's exactly right if this debt ceiling issue becomes a turning point for the US to default, it will be a new beginning of a new global economy which would be independent from the United States or any other national economy, it will be a world order which will be more interdependent than what we are seeing right now.
SIMON LAUDER: The US government will start running out of money to pay its bills if there's no resolution by the 17th of October.
SHANE MCLEOD: Simon Lauder reporting.You’ve traveled the world and seen it all. You’ve set foot on nearly every continent and absorbed the landscapes of numerous countries and locales. Now, you are scouring the globe for more exhilarating experiences to satisfy your craving for thrills and adrenaline-fueled excitement. For the hard-core action sports enthusiast, the more audacious and daring the journey promises to be, the better. The following list presents some unconventional activities for thrill-seekers longing to up their game and transform their next vacation into an unforgettable action sports adventure.
Zorbing
Zorbing is a quirky sport that involves running down a hill or across a body of water in a giant inflatable plastic ball—all in the name of fun. The activity originated in New Zealand, but its popularity has expanded across the globe, making it a widely accessible sport, no matter where you plan on travelling. Also an entertaining source of exercise, Zorbing is a fantastic way to bond with friends, and the sport has given birth to several water and land-based competitive events, a sign of its staying power and expansive cult following. Some Zorbing locations even offer amazing obstacle courses to test your mettle, adding to the challenge (and hilarity) of this unique recreational activity.
Ice Sea Swimming
Brisk and bracing, thrilling and memorable, ice swimming is a popular activity, especially in the Nordic countries of Iceland and Finland. Not for the trepidatious traveler, ice swimming involves taking a quick dip in frigid lake or ocean waters, and then following it up with a relaxing respite in a geothermally heated pool or sauna. First-time ice swimmers report a brief, yet chilling shock that gives way to a light tingling sensation all over their body. Some devoted ice swimmers believe the activity helps regulate and improve blood circulation, suggesting positive health benefits as well. Though it’s not for everyone, ice swimming can make for an amusing story to tell your friends or colleagues later.
Volcano Boarding
If you wish to experience the thrill of tobogganing without the wintry weather, then you should try sliding down the slope of an active volcano. Pioneered by an Australian tourist in Léon, Nicaragua, volcano boarding puts a fresh spin on a well-worn activity of sledding, and with some experience and practice, you can descend down the face of a volcano at blistering speeds—a perfect activity for even the most hard to impress action sport enthusiasts. The views are spectacular as well, and the hike up the volcano makes for a vigorous workout. Surfing down the slope of a volcano is an off-the-beaten-path way to enjoy one of the world’s most magnificent natural wonders.
Zip-lining
Imagine soaring at lightning fast speed over a lush, sprawling forest, your feet dangling and your heart racing the entire time. Zip-lining—an activity obviously enjoyed best at high altitudes—is not only a thrilling and daring adrenaline rush but also a fantastic way to spend time soaking in the great outdoors. A bucket-list item for every adventurer or action sportsman, extreme zip-lining is an invigorating way to add vitality and exhilaration to your next vacation. Whether you are traveling to the cool and breath-taking Smoky Mountains or taking on one of the world’s longest zip-lines in Sun City, South Africa, this recreational activity will leave you wanting to go one more time.
Snowmobiling
Snowmobiling is a high-octane sporting activity that allows participants to shred some serious powder while experiencing some incredible (and chilly) thrills. Suit up and put on your helmet first, and then feel the rush of the snowmobile’s roaring engine as you drive across a frozen plain or on top the icy expanse of an Arctic glacier. The more space you have to roam, the greater possibilities for trying high-speed tricks and techniques. Plus, nothing beats the energy rush of speeding down a glacier slope at extremely high velocity, the cold mountain air beating against your body and giving you goosebumps the entire way.For those moments when you can’t think what to make here’s a little game to try. This is the first really really simple introductory video. Look up the others You Tube Gilly Hunt 14 – Gilly Hunt 20 for 7 differing ability video projects to try.
For casual wild fishing friends, it is obviously unrealistic to bring a big pole to go fishing, and it is not necessary. Therefore, according to the different fishing conditions, water depth, time period, etc., it is very important to quickly replace the bait, a strong and convenient pin. The following are some of the quick pins commonly found in fishing lure, also called connectors and so on.
Shape: long gourd type, short fat gourd type, usually upper (connected to the main line end) small under the big (connected to the bait end).
The purpose of adding the 8-word swivel is to reduce the spiral shape on the main line, especially in the process of fast feeding, the bait is rotated in the water, and the main line is driven and tightened, just like the clockwork. This phenomenon usually occurs more on sequins and iron plate type baits. The use of this method is also commonly used on such bait, because there is a weight--Mino, wave, VIB, etc. will change the state of the bait.
The short fat type pin has a larger circle at the lower end, and the swinging space of the bait is larger, and the long strip type can be selected according to the bait and personal preference. In terms of steel wire, steel is selected, and the toughness is higher. The reinforcement is better, usually stainless steel wire. The surface has natural color and blackening treatment, and it is not easy to rust. The shape of the buckle is usually a 90-degree bend and a U-bend. Each has an advantage. The U-shape is not easy to slip off, but it is difficult to hang the bait. The 90-degree bend occasionally encounters self-slipping. In short, it is best to get a good look at the bait.
Number: According to the size and weight of the bait and the conventional size of the fish in the fishing field, the fresh water is usually used at 00-0-1, and the static pulling force is at 9-20 kg. There is a giant thing, the pin has weight, small The bait and the light bait are small and vice versa.Effects of quantum corrections on the criticality and efficiency of black holes surrounded by a perfect fluid

We study some properties of the extended phase space of a quantum-corrected Schwarzschild black hole surrounded by a perfect fluid. In particular we demonstrate that, due to the quantum correction, there exist first and second order phase transitions for a certain range of the state parameter of the perfect fluid, and we explicitly analyze some cases. Besides that, we describe the efficiency of this system as a heat engine and the effect of quantum corrections for different surrounding fluids.


I. INTRODUCTION
In the early seventies, Bekenstein proposed the idea that black holes have entropy and that this entropy is proportional to its area [1,2]. At that time this idea was received with incredulity, since classical black holes cannot emit radiation, which means that they cannot have a well-defined temperature. It was Hawking who showed that, when quantum effects are taken into account, a black hole can indeed emit radiation, and this radiation can be understood as the radiation of the black hole as a perfect black body [3]. Since then, several authors have studied such implications, and one of the most interesting is the possibility that black holes undergo phase transitions in the same way some thermodynamic systems do.
In daily life, the most usual transition we are aware is the phase transition of water becoming ice or vapor. Such transition occurs for some fixed temperature (isothermal curves) where the volume of the system varies for a fixed pressure. It can be modeled, as a first approximation, by the Van der Wall equation of state. One can be led to ask if some analogue procedure can also happen for a black hole, and for such task it is compulsory to properly define what is the pressure of the black hole. This issue is not straightforward, since for the most simple black hole, based on the Schwarzschild metric, a proper definition of pressure appears to be lacking. This issue was solved by Kastor, Ray and Traschen [4] by the use of the cosmological constant as a pressure term and the identification of the black hole's mass with the enthalpy. Recently, Kubiznak and Mann [5] were able to study the P − V diagram of such thermodynamic black hole. Following these lines, one is able to identity the Schwarzschild anti-de Sitter spacetime as a full
