Risks of Diving
Diving has exposed the public to the many underwater wonders of the world. The beauty of the various kinds of life that is in the deep blue hides the biggest danger of diving. It isn't sharks or boats or anything else that may exist on or in the water. The real danger to divers is Caisson disease, or decompression sickness.
Anyone who goes from a high pressure to low pressure environment can be afflicted by the disease which is also known as the bends. The disease is a result of Henrys law, which in summary states that gas will form bubbles in a fluid when the pressure goes down. In terms of the bends, nitrogen is typically the gas and the blood is the fluid.
When the process occurs gradually, such as in an airplane cabin, the lungs have enough time to remove the gas before the bubbles form. When it occurs quickly, such as in the case of a diver surfacing too fast, it may result in itching skin and rashes, pain in the joints, paralysis and potentially death.
How to avoid the bends
To prevent the bends, the diver must give the gas a chance to naturally de-gas by ascending slowly. Calculating the time required to come up can be very difficult due to the number of variables that need to be taken into consideration. This is the primary reason as to why dive computers were developed. Timers and sensors are used by dive computers to determine the depth of a diver and the exact duration of the time the diver was at that depth. Calculations are performed by the diving computers in real time and determine the correct process for the diver to ascend without causing the bends.
A dive computer in just about every brand and model is able to sense the exact duration of divers being at certain depths. The diving computer can then estimate the blood gas level of the diver and figure out: the time period in which the diver can surface without having to worry about the bends; the duration of the divers stop at each depth in order to surface safely and the maximum depth the diver can reach amongst other things.
The Diver Interface
The display interface for various forms of divers computer have varying designs, however for the display to be practical it must be clearly read and visible while diving. It should not be cluttered, so the diver does not experience information overload. Further to this, better models of diving computers will be able to give useful information like water temperature, the required decompression time at each depth and dive resurface rate. The top ranging models are able to transmit the entire dive data to a computer for later analysis.
There are also other features that can really set the dive computer ahead of the pack. Once a diver has surfaced, these upper end diving computers will display the time before a diver can board an airplane. That is one of the quickest ways to achieve the bends, is to board an airplane too soon. Other upper end models will also keep track of the air supply available from the diver's tank.
When it comes to buying a dive computer for yourself, you should check to see how much information is provided on the display and whether or not the display is clear and visible, for practicality underwater. You should also check for other features and see what underwater variables are being kept track of in terms of dive quantities. A recommended choice of an excellent diving computer would have to be the Suunto D9.
A pressure cooker allows you to quickly prepare a pot of beans or a pot roast. The food is quickly cooked in a pressure cooker as it creates a seal that retains air and moisture. Actually you will be able to cook the meal at a higher temperature as the water within the cooker has a higher boiling point. Higher temperature leads to faster cooking, but without the risk of drying out meat or whatever you are cooking. Most foods will be prepared at about a third of the time than the one needed in the case of other cooking methods.
The good news for vegetarians is that their beans, rice and staples - that would take at least 40 minutes to cook - can be prepared and served in roughly 10 minutes. Most vegetables and softer foods need only a couple of minutes to be cooked. Those who are on a low carbohydrate diet can greatly appreciate the benefits of a pressure cook, as they can easily make meal tendered a lot cheaper. Just imagine you could cook an entire chicken in roughly 20 minutes. Pressure cookers are quite heavy and robust, precisely because of what they are designed to do: maintain high pressure within the device. These appliances are available in many sizes, so you might want to have two units. A small pressure cooker is great for vegetables, potatoes and rice, while a larger one is perfect for roasts and poultry.
The larger pressure cooker is most adequate for some ribs or for stuffed peppers. You could cook the ribs in the pressure cooker for a few minutes, to make meat tender, and then grill them a little bit pouring some of your favorite barbecue sauce on top of them. All these cooking can be done in a really short time. A pressure cooker is also an excellent option when you are in a hurry to get to the office in the morning. There are situations when you have no time to put the food in a slow cooker in the morning. In such cases, when you finally get home, you just need to put the food in the cooker and it will be prepared by the time you arrange everything else for dinner.
Keep your tea. Give me coffee any day, as Sydney Smith said, ?If you want to improve your understanding, drink coffee; it is the intelligent beverage.?
Legend has it that an Ethiopian goat herd first recognized the magical powers of red coffee berries, when he noticed how frolicsome his goats became after eating them sometime around AD 800. He tried some, so the story goes, and the effect was so ecstatic, that he ran straight to the local priests with his discovery. They tried them and stayed up all night in rapture with the divine. The legend of coffee was born.
Although the truth of this story is controversial (some say that it was first brewed in Arabia circa AD 1000) we know that the magic beans didn?t leave Africa or Arabia until they were smuggled out nearly 600 years later. The first coffee arrived in Europe in 1615, and the rest as they say is history ? although politics surrounding the spread of coffee were far from simple. Our ancestors recognized that coffee is more than ?just? a drink.
Fast-forward to the 21st Century and the same passions still emerge amongst those who, like me, are confirmed coffee drinkers. Instant doesn?t really count ? it?s little more than flavoured water. But proper coffee made in a proper coffee pot; now that?s a different story. Cafetiere, filter, espresso drink machine ? everyone has a favourite method. However, there is one drawback; good coffee takes time.
At home, the only reason that I make tea is lack of time. At work it gets a little more complicated ? there?s that underlying assumption that you at least have to offer to make colleagues a drink. Fine if it?s tea or instant, but making real coffee for everyone else is often just a drag. As the smell pervades the room, it?s easy to feel like the office coffee machine as you fill the second cafetiere. Perhaps the effort required to prepare coffee makes it taste so good? I?d always assumed this and been rather scathing of any form of drinks machine that claimed to make proper coffee. There?s no way that you can just push a button and get a decent drink ? in fact I?d go so far as to say, that the only way to achieve effort free coffee is to get a friend, maid or butler to make it for you.
This conviction has just landed me right in it. Whilst waiting for a meeting I was offered the choice of fairtrade or decaf. Decaf goes against my religion, so I almost asked for tea when I saw that it was coming from a machine. After all, the words ?instant? and ?coffee? shouldn?t appear in the same sentence. But the drink I got didn?t taste like insipid dishwater; it was proper coffee.
In a brief moment, when I thought no one was looking, I tried to investigate the machine, looking for the trickery. Needless to say, my cheeks turned hot as freshly poured coffee when I was caught peering behind the machine. Explaining that I was looking for the ?hidden butler? really didn?t help?
