Juggling Five Balls Of Life

English: Picture taken of me juggling.
The 5 balls of life speech by Coca-Cola’s former CEO Brian Dyson (1986-1994) is one of the most viral speeches circulating on the web. Very much in line with Apple founder Steve Jobs’ announcement speech at Stanford University, Dyson addresses the priorities in life using the metaphor of juggling 5 balls. He calls the balls work, family, friends, health and spirit.




Imagine life as a game in which you are juggling some five balls in the air. You name them work, family, health, friends and spirit. And you’re keeping all of these in the air.
You will soon understand that work is a rubber ball. If you drop it, it will bounce back. But the other four balls – family, health, friends and spirit – are made of glass. If you drop one of these, they will be irrevocably scuffed, marked, nicked, damaged or even shattered. They will never be the same. You must understand that and strive for balance in your life.You live in a world of growing opportunity at one of the most exciting times in history, and you have been prepared with an exceptionally fine education. Because you are all so well educated, let me pose this final question to you. What is education for? Is it for the pursuit of knowledge or for the pursuit of significance? How you answer makes a difference.Knowledge is merely a tool. There is someone in Argentina or Singapore who has the same degree as you. The difference lies in how you use it. Will you use your education for life or just as a living? It’s up to you now.

Possible reason for Samsung Note & battery Explosition

The Note 7's lithium-polymer battery is a flattened "jelly-roll" consisting of a positive layer made of lithium cobalt oxide, a negative layer made of graphite, and two electrolyte-soaked separator layers made of polymer. The separator layers allow ions (and energy) to flow between the positive and negative layers, without allowing those layers to touch. If the positive and negative layers ever do touch, the energy flowing goes directly into the electrolyte, heating it, which causes more energy to flow and more heat - it typically results in an explosion. Compressing the battery puts pressure on those critical polymer separator layers that keep the battery safe.

Samsung stated that these separator layers may have been thin to start with due to aggressive manufacturing parameters. Add some pressure due to normal mechanical swell from the battery or accumulated stress through the back cover (e.g. from being sat on in a back pocket), and that pressure could be enough to squeeze the thin polymer separator to a point where the positive and negative layers can touch, causing the battery to explode.

Not all opportunities are to be taken


Lessons from this picture:
  1. Not all opportunities are to be taken. Some are traps.
  2.  A person can become so determined to destroy another person that they become blind and end up destroying themselves.
  3. You fight best in your natural element and environment. Here the bird has advantage in his natural element.
  4.  Know your limits, we all have them.
  5. Sometimes the best response to provocation is not to fight.
  6. Sometimes to accomplish something you need team work, you will not always win alone.
  7. Stick to what you do best and don’t pursue what will kill you.

Ebola

Русский: Изображение вируса Эбола полученное с помощью просвечивающей электронной микроскопии. 中文: 電子顯微鏡下的伊波拉病毒結構. Türkçe: Ebola virüsü. Føroyskt: Ebola virus, eitt (-)ssRNA virus, undir elektronmikroskopi. (Photo credit: Wikipedia)

Ebola virus disease (EVD), formerly known as Ebola haemorrhagic fever, is a severe, often fatal illness in humans. Signs and symptoms typically start between two days and three weeks after contracting the virus, with a fever, sore throat, muscle pain and headaches. Then, vomiting, diarrhoea and rash usually follows, along with decreased function of the liver and kidneys. At this time, generally, some people begin to bleed both internally and externally. Death, if it occurs, is typically six to sixteen days after symptoms appear and is often due to low blood pressure from fluid loss.
The virus is acquired by contact with blood or other body fluids of an infected human or other animal. This may also occur by direct contact with a recently contaminated item. Spread through the air has not been documented in the natural environment. Fruit bats are believed to be the normal carrier in nature, able to spread the virus without being affected. Humans become infected by contact with the bats or a living or dead animal that has been infected by bats. Once human infection occurs, the disease may spread between people as well. Male survivors may be able to transmit the disease via semen for nearly two months. To diagnose EVD, other diseases with similar symptoms such as malaria, cholera and other viral haemorrhagic fevers are first excluded. Blood samples are tested for viral antibodies, viral RNA, or the virus itself to confirm the diagnosis.
The Ebola virus causes an acute, serious illness which is often fatal if untreated. Ebola virus disease (EVD) first appeared in 1976 in 2 simultaneous outbreaks, one in Nzara, Sudan, and the other in Yambuku, Democratic Republic of Congo. The latter occurred in a village near the Ebola River, from which the disease takes its name.
The current outbreak in west Africa, (first cases notified in March 2014), is the largest and most complex Ebola outbreak since the Ebola virus was first discovered in 1976. There have been more cases and deaths in this outbreak than all others combined. It has also spread between countries starting in Guinea then spreading across land borders to Sierra Leone and Liberia, by air (1 traveller only) to Nigeria, and by land (1 traveller) to Senegal.
The most severely affected countries, Guinea, Sierra Leone and Liberia have very weak health systems, lacking human and infrastructural resources, having only recently emerged from long periods of conflict and instability. On August 8, the WHO Director-General declared this outbreak a Public Health Emergency of International Concern.
A separate, unrelated Ebola outbreak began in Boende, Equateur, an isolated part of the Democratic Republic of Congo.
The virus family Filoviridae includes 3 genera: Cuevavirus, Marburgvirus, and Ebolavirus. There are 5 species that have been identified: Zaire, Bundibugyo, Sudan, Reston and Taï Forest. The first 3, Bundibugyo ebolavirus, Zaire ebolavirus, and Sudan ebolavirus have been associated with large outbreaks in Africa. The virus causing the 2014 west African outbreak belongs to the Zaire species.
Outbreak control requires a coordinated series of medical services, along with a certain level of community engagement. The necessary medical services include rapid detection and contact tracing, quick access to appropriate laboratory services, proper management of those who are infected, and proper disposal of the dead through cremation or burial. Prevention includes decreasing the spread of disease from infected animals to humans. This may be done by only handling potentially infected bush meat while wearing protective clothing and by thoroughly cooking it before consumption. It also includes wearing proper protective clothing and washing hands when around a person with the disease. Samples of body fluids and tissues from people with the disease should be handled with special caution.
No specific treatment for the disease is yet available. Efforts to help those who are infected are supportive and include giving either oral rehydration therapy (slightly sweetened and salty water to drink) or intravenous fluids. This supportive care improves outcomes. The disease has a high risk of death, killing between 25% and 90% of those infected with the virus, averaging out at 50%. EVD was first identified in an area of Sudan (now part of South Sudan), as well as in Zaire (now the Democratic Republic of the Congo). The disease typically occurs in outbreaks in tropical regions of sub-Saharan Africa. From 1976 (when it was first identified) through 2013, the World Health Organization reported a total of 1,716 cases. The largest outbreak to date is the ongoing 2014 West African Ebola outbreak, which is currently affecting Guinea, Sierra Leone, and Liberia. As of 22 October 2014, 9,964 suspected cases resulting in the deaths of 4,881 have been reported. Efforts are under way to develop a vaccine.
Symptoms of Ebola are treated as they appear. The following basic interventions, when used early, can significantly improve the chances of survival:
  • Providing intravenous fluids (IV)and balancing electrolytes (body salts)
  • Maintaining oxygen status and blood pressure
  • Treating other infections if they occur
  • Experimental vaccines and treatments for Ebola are under development, but they have not yet been fully tested for safety or effectiveness.
Recovery from Ebola depends on good supportive care and the patient's immune response. People who recover from Ebola infection develop antibodies that last for at least 10 years, possibly longer. It isn't known if people who recover are immune for life or if they can become infected with a different species of Ebola. Some people who have recovered from Ebola have developed long-term complications, such as joint and vision problems.

MEP Fix Classification


First fix comprises all the work needed to take a building from foundation to putting plaster on the internal walls. This includes constructing walls, floors and ceilings, and inserting cables for electrical supply and pipes for water supply.

Second fix comprises all the work after the plastering to a finished house. Electrical fixtures are connected to the cables, sinks and baths connected to the pipes, and doors fitted into doorframes. Second fix work requires a neater finish than first fix.

The division of work is a convenient description because electricians, plumbers and carpenters will probably have to make two separate visits to one property under construction, at separate times. Project managers can report "first fix complete" or "second fix 50% done" and others can understand.

The installation of this equipment takes place in the "third fix" segment of a construction project. It is especially important that installation of sensitive electronic equipment be installed only when a construction site is dust-controlled and prepared for what would be considered "dust free" conditions

Mechanical:

Plumbing (Drainage/Water Supply & Fire Fighting)

  1. First Fix: Surveying, Marking, Supports and Brackets Installation    
  2. Second Fix:
  • Stage 1: Installation of Main Plumbing Header & Branch pipe
  • Stage 2: Insulation of Branch pipe & Installation of droppers with Valve accessories
  • Stage 3: Testing of Main & Branch Pipe lines
  1. Final Fix: Installation of Hose Bib & Sanitary fixtures (All Exposed Plumbing Items)
  2. Equipment Installations: Sump Pump & Water Heater (All Plumbing Long Lead Items)

 

HVAC

  1. First Fix: Surveying, Marking, Supports and Brackets Installation
  2. Second Fix:
  • Stage 1: Installation of Ducts/CHW/Refrigerant Pipe
  • Stage 2: Insulation of Branch Ducts/CHW/Refrigerant Pipe & Installation of droppers with Valve Accessories
  • Stage 3: Testing of Main & Branch Ducts/CHW/Refrigerant Pipe
  1. Final Fix: Installation of Grilles & Diffusers (All Exposed HVAC Items)
  2. Equipment Installations: Chillers & AHU's (All HVAC Long Lead Items)

Electrical

  1. First Fix: Surveying, Marking, Supports and Brackets , install conduits & back boxes in wall
  2. Second Fix:
  1. Final Fix: Installation of Light Fixtures (All Exposed Electrical Items)
  2. Equipment Installations: HV Switch gear & DB's/SMDB's/LCP's (All Electrical Long Lead Items)

Note:
High Level Installations refers MEP Works in Ceiling Void Space
Low Level Installation refers MEP works below the false ceiling board enclosure
Generally MEP Risers are given more importance .It has separate WBS named Risers in which respective risers are mentioned it is not classified in to fixes

L is for Lien

Contractors, subcontractors, suppliers and consultants cite "not getting paid" as one of the biggest challenges to operating in the construction industry in Qatar.  Understandably, companies are starting to look for opportunities to secure payment.  Effective, practical methods are proving difficult.  Liens are not without their difficulties but are another method to throw into the mix.
A "lien" is a priority right over property, moveable or immovable. Liens can arise where money is due from one party to another in order to satisfy or secure that debt.  In its simplest form it is hanging on to goods/materials/equipment which are properly in your possession but belong to someone else; someone whom owes you money.  In the construction context this becomes more difficult when those goods or materials are delivered and incorporated into a building or structure.  At this stage the lien is exercised as a "priority right", or an "attachment", broadly similar to a mortgage over a property.
A supplier has a lien or priority right over the materials supplied for as long as they maintain their "intrinsic nature".  Again, in the construction context, once incorporated into a building or structure they are likely to be inseparable, no longer of the same intrinsic nature.  A further problem arises if the goods or materials are sold on and the purchasing party knows nothing of the debt owed to the supplier – in these circumstances the lien may be lost. 
There is a risk that the goods or materials may be subject to other priority rights.  Judicial costs, costs of sale, costs of preserving or storing the materials, and wages to workers all taking precedence over the supplier's right to recover the debt it is owed.
Qatari law makes specific provision to cover the fees of contractors and designers whose work is in immovable property. i.e. The construction, rebuilding, restoring or maintaining of buildings or installations.  Such contractors and designers have a priority right over the building or installation to the extent of the value in the building or installation arising from the work of the contractor or designer. 
These priority rights must be registered as a charge over the property. They will rank behind other prior registered charges save where the prior registered charges were in existence before the works carried out by the contractor or designer added value to the property.  Registered charges whilst securing a debt may do little to assist in the short term as the contractor or designer, the lien holder, may not be able to force the sale of the property to recover its money.
Some contractors are deprived of the opportunity to secure payment by way of lien or priority right by being obliged to provide waivers or releases.  A release indicates completion and payment, or that a claim has been satisfied.  Releases may be required as a pre-condition to payment or to the issue of a taking over or initial acceptance certificate.  A waiver is typically obtained before commencement of the works and may be drafted into the terms of the contact itself.  A waiver relinquishes any existing or future right to a lien/priority right.
It is sensible for the construction client to protect itself by requiring that a contractor provide waivers or releases from its subcontractors.  This avoids a subcontractor registering a priority right over a property due to non-payment by the contractor where the contractor has been correctly paid by the client.

Eichleay Formula Calculations

Home Office
Home Office (Photo credit: Wikipedia)This paper is intended to be a fairly straight forward explanation of how to perform Eichleay formula calculations. It is not a definitive text on calculation of delay damages. There are normally many components to consider when calculating delay damages and the Eichleay formula deals with only one of these components.

The Eichealy Formula is widely used as a method of calculating home office overhead damages in construction delay cases. This component of delay damages often accounts for a very large portion of the amounts claimed.

If you are currently dealing with a case or claim involving construction delays you will probably need more information than is presented here. Construction delay claims are among the most complicated claims and almost always require the services of an expert to both determine damages and to defend against them.

Information presented in this article is categorized into the following specific sections.
  • The basic formula
  • A sample calculation
  • Problems associated with using and applying Eichleay

The Basic Eichleay Formula


The basic Eichleay calculation normally comes at the end of a project when all work has been completed. In that case, the following 3 step calculation is used to determine damages.

1. Allocable Overhead. This is a calculation to determine the portion of the home office overhead that should be allocated to this project. This project is expected to pay it's fair share of home office overhead and this is a way of calculating that amount.



2. Daily allocable overhead. Next, we want to determine a daily rate for the allocation of home office overhead.



3. Home office overhead damages. This is simply a matter of multiplying the number of compensable delay days by the daily allocable overhead rate.



A sample basic calculation


Let's assume that we have a contract amount of $2,700,00. The contractor has suffered compensable delays amounting to 45 calendar days. During this period, the contractor has 5 projects underway whose aggregate value is $10,000,000. The contractor's home office overhead during this period totaled $250,000. The duration of this project, including delays, totals 265 days. Our sample calculation of home office overhead damages follows:

1. This project's allocable overhead



2. Daily allocable overhead.




3. Home office overhead damages. This is simply a matter of multiplying the number of compensable delay days by the daily allocable overhead rate.



Thus, in this case, our contractor's claim is $11,462 in compensation for home office overhead that should have been allocated to this job because of the increased duration of the project.

Problems Associated with applying the Eichleay Formula

The Eichleay formula is considered an estimate or an approximation and it's accuracy can be questioned. Even so, the Eichleay formula is generally considered to be a reasonable basis for estimating the amount of unabsorbed home office overhead resulting from construction delays.

It is reasonable when questioning the validity of Eichleay calculations to demand that the calculations be based upon audited financial statements to determine actual home office overhead costs. Many small contractors may not have audited information available and even larger contractors may not have audited information available immediately upon the completion of a project.

An objection to the inclusion of certain components in the value of home office overhead may arise. For example, on public works projects which are obtained through hard bidding, the cost of advertising and entertainment may be disallowed.

Some state courts may not recognize Eichleay as an acceptable method for calculating delay damages.

It can be difficult to accept Eichleay calculations if the delay occurs late in the project. As an extreme example, if the delay occurs when the project is 99% complete, it can be argued that all allocable home office overhead expense has already been paid to the contractor.
