Technology in Sports

It today’s world, sport cannot go together without technology. With the ever growing development of new technologies, they have always tried to be implemented into sports. Because technology can give sports something nothing else can, an unmistakable truth. Or so they say. Due to the fact that people are, well, people, they are bound to make mistakes. It is because we are human, we are not robots, that we can make mistakes, while robots make them only if they are malfunctioning. This is especially emphasized in sports, where human eyes can often deceive their owners, the referees most importantly, but also players, coaches and the fans. That is why these days there are many discussions about installing video technology into sports, mostly football. What does technology actually mean for sports?

Here I would like to emphasize that there are already sports using technology, like tennis and cricket, to name some. It helped the referees a lot, to minimize and correct some mistakes they make. But apparently, not all problems are solved like this. Players that have been playing for a longer period of time, and have not grown up with these kinds of technologies, are not convinced that it works properly. This suspicion is probably understandable, because when they were first starting their professional sports careers, they did not probably even dream about something like this would exist. But this technology has been tested time after time, and skeptical players, such as Roger Federer, have learned to live with it and accept it, although probably not so reluctantly.

This technology used in sports is called Hawk-Eye line-calling system, or just Hawk-eye for short. It was invented by a British computer expert Paul Hawkins. It is now used in tennis, where six or more cameras, situated around the court are linked together, track the path of the ball. Then those six or more cameras combine their separate views and make a 3D representation of the path of the ball. For tennis, or basically any other sport, this means that any close line call can be checked, quickly and accurately. This is not always used on tennis tournaments, though. For instance, the French Open is not using this technology because the tournament is played on clay courts and thus the print of the ball on the ground can easily be seen. Maybe this will change one day, because you can’t always be 100% sure you are looking at the right print.

These days there have been a lot of talks about introducing this technology to the sport of football. The sympathizers of this idea have been especially loud after the South Africa FIFA World Cup 2010, where a lot of mistakes by the referees have been made (an Argentina goal allowed although the player was offside, England goal not seen in a crucial moment). However, referees are only human, and they are bound to make mistakes because they can not help it, so i do not think all those critics were fair to them. On the other hand, a recent statement was made from the UEFA president Michel Platini, who is not thrilled about the goal-line technology, saying that this would reduce football to a video game. I don’t believe that other sports who have this technology have been reduced to a video game. Furthermore, he also admits that referees can make mistakes and that there are many cameras on the field that can catch any disputable moment. So why not help football, or any other sport, to see these disputable moments clearly and to resolve them without making mistakes. Or is it better to hear a mass of critics every time something like this happens? I am sure the referees would like this kind of help, then they couldn’t be blamed for anything and wouldn’t have to listen to all the nonsense people say about them the other day, or worse.

Lubrication of Domestic Clocks

Domestic clocks are one of the most ignored watches in the entire household. We make sure that our wrist watches are well maintained with good servicing, battery changes and of course lots of lubricating. But domestic watches are practically ignored till the battery runs down. Even then, we just replace the battery without getting any servicing or lubricating done on it. That means that the watch continues to run without any care or oiling till they finally expire and die! But just like wristwatches, domestic watches need to be maintained well too with regular cleaning and lubrication and care. Clocks are larger than wristwatches so a little too much lubrication is OK here.

But still there are rules to be followed in lubrication and care of clocks like-

* Try to use just a single drop of oil in the watch works to make the watch remain on time. These are bigger watches so they don’t really require you to be precise but it’s a good idea if you are. Carriage clocks require a smaller amount while long clocks and grandfather clocks require much more.

* Try not to scrape the oil pots while oiling watches as it scrapes up unnecessary settled grit into the workings of the clock. This is especially true of incalite pots. Use only fresh oil and discard any which has more than five years on the packing date on the seal; protect the oil you are using by storing it at room temperature and away from direct light. An ideal temperature would be about 15 to 20 C or as stated by the manufacturer of the clock. There are several points on a domestic clock where you can oil them and the oil will them spread to all over the clock workings. Good places to apply lubrication are at oils sinks or pivot holes, escapement pallet faces, weight pulley bearings and points of contact between different parts of the mechanism.

* Make sure you do clean the mainspring and refit the watch springs after you have oiled the domestic wall clocks. You can also apply heavy grade mineral oil around the edges of the barrel cap. Capillary action will make sure that the oil spreads all over the mechanism.

* Do not lubricate or oil pinion leaves and gear teeth, as they will slip while revolving. Another place to be careful of is the ratchet and the great wheel arbor in the main clock facings.

* The frequency of oiling depends on how frequently you use the clock and the location it is based in. Synthetic oils are very stable and do not deteriorate but non-synthetic oils do. The residue leaves a gummy deposit in the watch that can destroy a good watch.

* Contamination with dust will however really cause a tremendous amount of wear on the clock and that can damage the mechanism. Reapplication of oils is fine after the old one has been wiped off.

But do make sure that you do service the watch at least every two years to maintain optimum working conditions.

Acne Medicine

Is acne making your social life hell? Is everyone giving you their valuable advice on how to get rid of acne? Have you tried and tested everything in the market without any success? Its time to do some research and find more about the products available and the effect they have on your skin. Acne is a very personal issue and any medication you should be personalized according to your individual habits. Here is important that you find out a few things like the type of your skin. If you have oily skin then you should use gel based products where as your skin is dry then you should use an acne cream. If your skin is sensitive then you should avoid too strong products or your situation may worsen.

The main cause of acne, unlike popular belief is not dirt or dust where as it is either genetic or caused due hormonal changes like puberty. Acne can strike both boys and girls depending upon their genetic make up. The washing washing face all the time may not be the solution rather washing two to three times a day with a mild cleanser may serve the purpose.
You can choose from natural or medicated medicines. Natural medicines are made of extracts of plants and naturally occurring substances. They are generally a blend of ingredients like Vitamin E, grape seed oil, calendula, aloe vera or witch hazel and essential oils. Although even natural medication may be strong and it is a fact that should be kept in mind by people of sensitive skin.

Medicated medicines contain chemicals that dry up the pimple while acting as exfoliate. The chemicals used most commonly are benzoyl peroxide and salicylic acid. The higher the percentage of chemical used, the stronger is the product. Higher concentration may harm your skin since it is important to choose wisely while applying any cream – be it medicated or natural.

Medication may be short term or prolonged dependent upon your condition. But no matter what you use it is important to alert oneself in case of any reaction or allergies that a medicine may cause if it does not suit your skin. Using medicines without proper supervision may have adverse effect and may cost you much more time and money if permanent damage occurs. Here is best advised to be careful while using any kind of medication.

How Rigs for Water Wells Operate

To find new artesian wells, technology absolutely has to help us. With technical and mechanical innovations together with hydraulic engineering it has been possible to build rigs that are more and more efficient and are able to go to very important depths while drilling even more resistant layers of rocks. An artesian well is an under earth rich reserve of pluvial water: it is about natural resources that are hidden in the earth’s ground, the precious water supply of an area can be more or less extensive. The drilled hole of an artesian well lets water spontaneously come up to surface, without the use of submersible pumps. To find this underground water it is thought necessary to use a rig that is appropriate to our aim. Modern rigs, designed and realized by companies from this sector, are able to drill into the layers of the earth for many hundreds of meters. We are talking about mobile rigs, i.e. mounted on trucks or trailer either big or small depending upon the dimensions and weight of the equipment; this will let us move the rig inside the working yard without too many problems.

The choice of the correct rig to drill water wells is a choice of fundamental importance. Depending upon the well’s depth the rig will need to be more or less powerful. The best way to find the most appropriate rig is to trust and search the internet. You just need to open the browser on Google or Bing pages and type “drilling rigs for sale”. Over the world there are many companies that are operating in the sector of designing and realizing rigs. There are companies that are specialized in building rigs dedicated to water research. Others do have rigs to drill inside mines. Others specialize in oil exploration in the deepest layers of the earth from either marine platforms or on the mainland. There are also bigger companies that offer a wider range of drilling equipment. It is not always necessary to buy a new drilling rig. Most companies suggest and offer to their clients the option to hire and sell used rigs which can be recommended for small works when it’s not necessary to use equipment for a long period.

It is possible to find rigs that are fit for any purpose; it is though important to know that not all rigs are equal. For instance there are mechanical rigs which normally operate by diesel engines. There are electrical drilling rigs powered by energy sources generated in the work place, often they have engines with internal combustion. There are hydraulic drilling rigs that are using hydraulic oil flow operated by diesel engine. The system includes one gear box on which are connected different hydraulic pumps. Moreover modern rigs do differentiate themselves for their drilling method; these rigs can work a percussion system or rotary drilling method. The first ones impact the ground vertically drilling a large diameter hole in the ground; these rigs are mostly used when searching for water at low depths, but with very large diameter. Other types of drilling rigs instead, operate by rotating movement with a specific tool, normally called a bit.
