Mount Everest: An Exhilarating Adventure (part 2)

Their findings were remarkable. Even at their base camp, the very low level of oxygen was noted to have a direct effect particularly on the saturation levels of blood oxygen. The usual percentage at sea level is 98% up to 99%, however at the base camp; the percentage fell to about 85% up to 87%. Even the blood samples that were taken from the summit area featured the oxygen's super low levels. With this phenomenon, the breathing rate vastly increased from approximately 20 up to 30 bpm or breathes per minute. Thus, it can even go as fast as 80 up to 90 bpm or breathes per minute. Climbers experienced exhaustion by merely catching their breadth. As a conclusion, exhaustion, lack of oxygen, extreme cold as well as the actual danger of climbing Mount Everest are factors that can contribute to the Mountain's death toll.

Reports of climbers dying in Mount Everest are usually left behind. According to record, approximately 150 bodies were never recovered. In fact, when you climb the mountain, corpses are very much visible even from the standard routes.

Another discovery about Mount Everest is that amidst its very high area, lightning does not plague it. Even the Lightning Detection System of NASA was not able to get any record of lightning episodes in the Tibetan mountains that range from 7,000 feet or 2000 meters and above, only along the fascinating Tibet plateau.

Moreover, in the expeditions to Mount Everest, climbers use oxygen tanks and masks when they are above 26,246 feet or 8,000 meters. Although Mount Everest can actually be climbed even without bringing supplementary oxygen, it still increases potential risks on the climber. This is justifiable because any person that experience low oxygen levels cannot think clearly. Plus, the low temperature, severe weather and very steep slope of Mount Everest necessitate accurate and quick decision making prowess.

This is why using bottled oxygen while ascending Mount Everest has become controversial. However, many attest to using this. Even the famous George Mallory was quoted as saying that using it is "unsportsmanlike". He later took this back when he realized it was very difficult to climb the summit without having one. He consequently used one during his climb. This was also very helpful during the initial successful summit of Hillary and Tenzing in 1953. After this, bottled oxygen has become a standard necessity for successful climbs to Mount Everest. The only dilemma, according to Jon Krauker's book called Into Thin Air, is that with the publicity of using bottled oxygen in Mount Everest, unqualified climbers are also trying and attempting to actually summit the mountain. For Krauker, this can lead to more dangerous situations and even deaths.

Thus, last May 11th of the year 1996, such disaster occurred when 33 climbers attempted to ascend Mount Everest and leaving bottlenecks at Hillary Step. This delayed several other climbers, being unable to go with the 2:00 PM turnaround time. This caused the proposal of banning the usage of bottled oxygen while climbing Mount Everest and should only use it for severe emergency cases. This would both decrease the growth of pollution in Mount Everest and this will keep off unqualified climbers from attempting to ascend the mountain. Aside from this, the 1996 disaster brought about the issue of having a guide use bottled oxygen as well. This is because many guides of Mount Everest do not use bottled oxygen. They regard it as a "false sense of security". The debate on this is about the inability of the guides to help their clients descend without the use of bottled oxygen.

Lastly, another issue in climbing Mount Everest is the reports about life-threatening thefts to climbers. The thefts were from the climbers supply caches. An example is an incident from the party of a certain David Sharp, where in the 1st Brazilian climber, Vitor Negrete died while descending Mount Everest. Speculations reveal that stolen supplies from his "high-altitude camp" contributed to this fatality.

Thus, Mount Everest is a very spectacular mountain. For climbers, it is an ultimate goal to actually ascend and descend it. For the rest of the world, it is a remarkable masterpiece of nature that should be nurtured and cared for.

Les règlements dans le domaine du transport

Afin de terminer la mise en œuvre du nouvel encadrement du camionnage en vrac, le gouvernement du Québec a adopté les quatre règlements suivants :
Règlement sur le courtage en services de camionnage en vracLe Règlement sur le courtage en services de camionnage en vrac s'applique au courtage en services de camionnage en vrac dans les marchés publics pour le transport de sable, de terre, de gravier, de pierre, de béton non transporté par camion muni d'une bétonnière, de béton bitumineux, y compris l'asphalte plané et l'asphalte recyclable et non recyclable, de matériaux résultant d'une démolition de route, de neige et de glace, de sel destiné à l'entretien des routes (Texte du règlement).
Règlement modifiant le Règlement sur les normes de charges et de dimensions applicables aux véhicules routiers et aux ensembles de véhicules routiers

Le Règlement sur les normes de charges et de dimensions applicables aux véhicules routiers et aux ensembles de véhicules routiers a été modifié en 1998 afin d’éliminer toutes les majorations de charge prévues quant à certains groupes d’essieux et à la masse totale en charge des véhicules suivants :

* les véhicules routiers d’une seule unité munis d’une benne basculante non amovible transportant du sable, de la terre, du gravier, de la pierre, du chlorure de sodium, de la neige, de la glace ou du béton bitumineux;
* les camions à déchets compactés à chargement arrière;
* les véhicules routiers d’une seule unité affectés au déneigement et au déglaçage des chemins publics; et
* les véhicules routiers d’une seule unité affectés à l’entretien des chemins publics lorsque l’année du modèle du véhicule est antérieure à 1992.

Ainsi, pour ces véhicules, la limite de charge de l’essieu tandem arrière (catégorie B.21) a été réduite de 20 000 à 18 000 kilogrammes. Conséquemment, la limite de masse totale en charge de ces véhicules, à l’exception des véhicules de déneigement et de déglaçage des chemins publics, est de :

* 25 250 kilogrammes dans le cas des véhicules à 10 roues;
* 32 000 kilogrammes dans le cas des véhicules à 12 roues munis d’un essieu tandem avant (catégorie A.3);
* 31 000 kilogrammes dans le cas des véhicules à 12 roues munis d’un essieu multiple avant (catégorie A.3);
* 31 000 kilogrammes dans le cas des véhicules à 12 roues munis d’un essieu tandem avant (catégorie A.4);
* 30 000 kilogrammes dans le cas des véhicules à 12 roues munis d’un essieu multiple avant (catégorie A.4).

Quant aux véhicules

Affectés au déneigement et au déglaçage des chemins publics, la limite de 7 250 kilogrammes sur l’essieu avant servant à l’établissement de la masse totale en charge a été remplacée par la charge maximale sur l’essieu avant afin de prendre en compte les équipements particuliers de déneigement situés à l’avant du véhicule qui, dans la plupart du temps, glissent sur la chaussée. La limite de masse totale en charge est établie en faisant la somme des charges maximales de chacune des catégories d’essieux sans excéder 19 000 kilogrammes pour ce type de véhicule à 6 roues et de 27 000 kilogrammes pour ce type de véhicule à 10 roues.
(Texte du règlement)
Règlement sur le contrat de transport forestierLe règlement a pour objet de prescrire les stipulations applicables à tout contrat pour le transport du bois n'ayant subi aucune autre opération que la coupe transversale, l'ébranchage et l'écorçage (billots, bois en longueur), en provenance des forêts du domaine de l'État.

Les stipulations du contrat de transport forestier sont celles paraissant au modèle visé à l'annexe A du Règlement sur le contrat de transport forestier et constituent les stipulations minimales que doit contenir tout contrat de transport forestier. Le contrat de transport forestier consiste en un formulaire semblable au modèle paraissant à l'annexe A du règlement, qui doit être rempli et signé par l'expéditeur et le transporteur.

SEO Habits Are Changing For Upcoming Businesses

Business that comes directly from websites, as well as internet advertising, is taking over all other forms of marketing and the competition is heavy. As a result of this many companies are increasing their budget for SEO (search engine optimization) purposes. Whereas this was often done in-house, many businesses recognise the need for this to be carried out by professionals to give them the best possible chance of beating the competition in the rankings war.

A study carried out by E-consultancy alongside neutralize - a search marketing agency - have shown that out-sourcing the SEO work and increasing spending on it, is a trend that a whopping sixty three per cent of companies intend to follow. With nine per cent of the companies surveyed spending more than 1 pounds million a year on paid search tactics and one in six investing a minimum of 50,000 pounds on SEO, this is truly big business and promises to continue growing.

Spending on internet advertising rose by thirty per cent in 2007 to 2.6 pounds billion and is head and shoulders above all other forms of advertising.

The study from E-consultancy on the SEO habits of 1,000 companies has culminated in a fifty five page report detailing company habits between February and March 2008. Apart from showing an increase in companies willing to outsource their SEO commitments, the report also shows that eighty six per cent of the organisations surveyed are paying to appear on Google's sponsored links and Yahoo's customers have jumped from forty five per cent to forty nine per cent for the same reason.

The report is good news for SEO companies but company bosses would be well advised to choose their provider carefully. Get in a cowboy company and this will do untold damage to your business, in the worst case scenario even getting your website banned from Google.

Some SEO companies will use tactics to push a website up the listings that are wholly unethical. This will bring about a temporary fix but as soon as Goggle pick up on it, your website will be dropped dramatically.

Keyword stuffing is one of the biggest issues that upsets Google and it is important that SEO companies find a balance between using the right keywords the right amount of times, leading to naturally readable content.

SEO companies hire professional writers to deal with content. Writing content for optimisation is a slightly different concept than your average writing techniques. It involves careful planning using keywords relevant to your site and finding a balance between these and the ones that are most often searched for to bring your site to the top of the rankings.

This becomes harder when the terms are generic and this is where an SEO company comes into its own. Using a combination of correctly worded meta data, well written content, linking and article writing, SEO companies will have tools at their disposal to ensure everything is specifically aimed to your site that the general company might not have.

When you know you have a product that works and a well written website it can be frustrating to not be getting the traffic from it that you think you deserve. This can be put right with efficient SEO tactics that are completely above board, that work within Google's limits and put your website higher up the listings, generating extra business for you and helping your company to thrive.

Always beware, when searching for an SEO company, that you do not fall for statements that promise to put you at the top of the search engines. Any SEO company worth your money will tell you that this is a constantly changing system and guarantees are not possible. An on-going campaign by a reputable SEO company will soon bring the results that you need.

Semi-Remorques

Une semi-remorque est une remorque routière destinée au transport de marchandises dont la particularité est qu'elle repose sur un ou plusieurs essieux à l'arrière et sur le véhicule tracteur à l'avant par l'intermédiaire d'une plateforme appelée sellette, de sorte que le tracteur supporte une partie notable du poids de la remorque et de son chargement. La semi-remorque, lorsqu'elle est dételée s'appuie au sol par l'intermédiaire de deux béquilles qui peuvent être commandées hydrauliquement, mais qui sont, pour des raisons de simplicité mécanique et de coût d'entretien, la plupart du temps commandées manuellement (par une manivelle jointe à un engrenage commandant une crémaillère).

Baisser ou bien remonter manuellement les béquilles lors de l'accrochage ou du décrochage d'une semi-remorque prend 3 à 4 minutes par opposition à quelques secondes avec un système hydraulique.

Par abus de langage, on appelle aussi semi-remorque (terme masculin) l'ensemble formé par le tracteur et la remorque. Cet ensemble s'appelle officiellement véhicule articulé. Il existe de nombreux types et dimensions de semi-remorques, selon le genre de transport à effectuer.

Mount Everest: An Exhilarating Adventure (part 1)

By: Christa Kowalczyk

Mount Everest is regarded as the Earth's highest mountain. The first publicized height of the renowned Mount Everest was established by India's Great Trigonometric Survey. This was in the year 1856 and with an estimated height of approximately 29,002 feet or 8,840 meters.

Mount Everest is regarded as the Earth's highest mountain. It is being measured according to its summit's height above sea level. This is actually around 29,029 feet or 8,848 meters. Aside from this, Mount Everest is also indicated as a portion of the acclaimed Himalaya range along High Asia, located just within the borders of Tibet in China and Sagarmatha Zone in Nepal.

Moreover, the first publicized height of the renowned Mount Everest was established by India's Great Trigonometric Survey. This was in the year 1856 and with an estimated height of approximately 29,002 feet or 8,840 meters. This is amidst the fact that Mount Everest was recognized as "Peak XV" at that time. It was only during the year 1865 when it was given its official name in English as "Mount Everest". This was implemented via the so-called Royal Geographical Society, upon the recommendation of India's British Survey General at that time, Andrew Waugh. Since, during his time Tibet and Nepal were closed for foreigners, Andrew Waugh was not able to have a local name proposed. This is amidst the fact that the Tibetans have used the name "Chomolungma" for centuries already.

Furthermore, during the latter part of 2007 or the climbing season, the ascents towards the summit were reported to have reached approximately 3,679 by about 2,436 individuals. Due to this, there were reported cases of not more than 210 deaths in Mount Everest. In fact, the conditions were so difficult most corpses were already left as is and these corpses are often visible from the standard climbing trails.

The noted climbers of Mount Everest were relative novices to experienced mountaineers. These people still count on paid guides to help them get to the top. These surges of mountaineers to the region are actually a vital tourist revenue source in Nepal. This is apart from the requirement of the government to have every prospective climber pay more or less a $25,000 per person for the permit.

Thus, Mount Everest has areas that are included in the list of Death Zones. This is because of its altitude that is above 8,000 meters or 26,246 feet. It is very difficult to actually survive in these areas. The temperature can go down to super low levels, causing frostbite to any part of the body that gets exposed in the air. Since the temperature becomes very low, snow is also frozen in particular areas, where in you can die by falling and slipping in such locations. Another potential threat is high winds as well.

Furthermore, at Mount Everest’s top part, the so-called atmospheric pressure is actually the sea level pressure's third portion. This means that there is only a third of oxygen breathable at such sea level. Last May 2007, a certain Caudwell Xtreme Everest made a study about the oxygen levels of a person's blood in extreme altitude. For this medical study, more than 200 volunteer climbers climbed towards the Everest Base Camp so as to be given medical tests with regards to the levels of blood oxygen in their body. Another team, a smaller group, also conducted tests while going towards the summit.

Mount Everest Base Camp Trekking in Nepal

By: David Stevens

Mount Everest is the highest mountain on Earth as measured by the height of its summit above sea level. The mountain, which is part of the Himalaya range in Asia is located on the border between Nepal and Tibet, China. There had been 3,050 ascents to the summit by 2,062 individuals.

Climbers range from experienced mountaineers to relative novices who count on their paid guides to get them to the top. This means climbers are a significant source of tourist revenue for Nepal.

There are great trekking tours available which is available to anyone who can walk for a few hours per day. These tours start in Nepal in Kathmandu and are very popular.

Mt Everest has an undeniable ability to seduce Explorers, Travellers and Climbers alike. With its breathtaking views and fascinating Sherpa people there is something for everyone to guarantee the experience of a lifetime.

Mt. Everest, so called after the first person to record its height, Sir George Everest, translates in Nepalese and Tibetan as Goddess in the Sky and Mother Goddess of the Universe, demonstrating the immense respect and reverence that the locals have for this awesome mountain. It is 29,029 feet high but it rises a few centimetres each year due to the huge geological forces acting on it.

The weather you will experience on Everest is extreme and rather unpredictable so it is best to be prepared for all eventualities. Spring is the high season for trekking, but warmer weather can mean there is a larger cloud cover, which obscures many of the fantastic views that are part of this once in a lifetime trek. For those willing to brave the colder temperatures of autumn and winter this is not such a problem.

A large problem on Everest is that as you reach higher altitudes the oxygen content of the air dramatically decreases. At 20,000 feet there is only half as much oxygen in the air as you are used to and by the summit oxygen is reduced to only a one third.

There are two times of year when conditions are most favourable for a trek to Everest Base Camp, either in the pre-monsoon springtime or the post monsoon autumn. Although, it is possible to join Treks that run almost all year round.

The main problem experienced on Everest is altitude Sickness, this is definitely something to take seriously and to take precautions against. There is no way of telling how it will affect you until you are at high altitude.

The easiest and most effective way to limit the effects of altitude sickness is by ascending the mountain slowly and giving your body time to acclimatise to the height. Above 10,000 feet (Base camp is at 17,500) you should aim not climb more than 1000 feet per day.

You also need to stay warm and conserve as much energy as possible, drink water and above all listen to what your body is telling you, if you don not feel right don not push yourself to hard because you may push yourself out of the trek altogether.

Make sure you pick the right trip for you, make sure you give yourself time to acclimatise to the altitude even if that means flying out a few days before your trek starts.

The Sherpa people are invaluable in making any expedition to Everest whether it be to Base camp or even Summit. They will carry your gear, food, tents and it is important that they are respected. They take great pride in their Mountain Climbing Heritage and without them you will not finish the trek

Wether you join a trekking tour or climb all the way to the top, it will be an experience to treasure for a long time!
