What to do when you are trapped in a lift??
We never know when and where accidents will happen to us OR people around us.
Read on and hope this piece of information may help any of us when things do happen to ourselves, our friends and our loved ones.
One day, while in a lift, it suddenly broke down and it was falling from level 13 at a fast speed. Fortunately, I remembered watching a TV program that taught you must quickly press all the buttons for all the levels… Finally, the lift stopped at the 5th level.When you are facing life and death situations, whatever decisions or actions you make decides your survival.
If you are caught in a lift breakdown, first thought in mind may be 'waiting to die'...But after reading below, things will definitely be different the next time you are caught in a lift.First - Quickly press all the different levels of buttons in the lift. When the emergency electricity supply is being activated, it will stop the lift from falling further.
Second - Hold on tight to the handle (if there is any). It is to support your position and prevent you from falling or getting hurt when you lost your balance.
Third - Lean your back and head against the wall forming a straight line. Leaning against the wall is to use it as a support for your back/spine as protection.
Fourth - Bend your knees . Ligament is a flexible, connective tissue. Thus, the impact of fractured bones will be minimized during fall.
For everyone, do send out this piece of information to all!

islamabad university blast
Today In Islamabad at around 5 pm 20-October-2009 A suicidal attack happened One after one (total two) in "International Islamic university Islamabad".two areas of this university where targeted one near cafeteria and other hits Shariat Faculty.
An Islamic university named International Islamic University new campus sector H-11 Islamabad the capital city of Pakistan was attacked
Due to this law and order situation All universities will be closed till 25/10/2009.
October is horrible for Pakistan. At same month 2005 8th of October Pakistan faced major disaster due to earth quake.And today Again a terrible situation happen.
Now this is the time to organize National civilian Defense Orgnization.
We have to train commoners so that we can resist from these type of attacks in right manners. We must achieve First aid training. In order to decrease death ratio of a bomb blast because these attacks usually based on gorilla tactics and planned at a public place.Usually Half an hour needed for emergency rescue squads to come and manage the situation.During this time we can save several lives by first aid.A training may be a good way to minimize problems.
These are some news from different news papers quoted as it is just for information about Islamabad Islamic university suicidal attack.
ISLAMABAD: A double suicide bombing at Islamabad’s International Islamic University on Tuesday killed up to seven people, including the two bombers, an administration official said.
‘Seven people, including two suicide bombers are dead, and 29 injured in the two attacks. Among the dead is one female,’ a senior administration official, Rana Akbar Hayat told AFP at the scene of the attack.
Police investigators confirmed that both were suicide attacks.
Speaking at the capital's main hospital, Interior Minister Rehman Malik said there were six dead — two suicide bombers, two men and two women.
The police arrested a suspect from the site of the blast.
The university is located in Islamabad’s sector H-11.
Eyewitnesses told DawnNews that there were between three to four thousand students present at the time of the blasts and that one bomb exploded inside a classroom.
The blasts occurred within a span of one minute at two campuses of the university.
Earlier in the day two bombs were defused at a girls’ school in Peshawar.
news from dawn new paper
ISLAMABAD : At least seven students were killed and 22 others were injured when two blasts ripped through the Islamic University Islamabad on Tuesday, Aaj News reported.
news from http://www.thepakistaninewspaper.com/news_detail.php?id=14853
According to initial reports one blast hit the Shariat Faculty and the other occurred near the cafeteria of university. A large number of students and faculty members were present at the time blasts.
Classes were also going on in the campus when the blasts occurred.
Police and rescue squads have immediately arrived on the spot. The injured are being shifting to PIMS hospital for treatment.
It is worth mentioning that many foreigners are studying in the Islamic University.

Windows 7 Ultimate Drive Encryption
Windows 7 Drive Encryption (Bit Locker)
It is the thing that you may know with such name that are:
TPM (Trusted Platform Module)
Encryption Chip
Bit Locker
All these are same thing introduced first on windows vista but only in 64 bit edition but windows 7 also provide this thing in 32 bit operating system. By this thing you can LOCK your drive with 128 bit encryption code. Its code cannot be open and if you lost it you cannot use your data. But the main thing here is that if you lose your code that means you have loosen your data but you can format your drive to use it again. One thing more that you need to know about your bit locker that whenever you encrypt your drive the system will make a recovery key for you that’s why you can use it when you lose your code or the password. You can save that recovery key in any USB divice.Or you can also save it in any folder it will be better to make more than one copy of key and upload your one key in your online hard drive or the sky drive or etc, and save other in USB and place it in a safe place.
You can also make your USB devices or any external HD encrypted. One thing more that if you will encrypt your system drive you must have to make the recovery of code or password in a USB divice because when you turn on your computer you have to put that USB device as a key of your computer or the laptop.But for this thing there must be the TPM chip installed in your machine.it is not the software it is a hardware divice.You can use this system on the other drive rather than the system drive if your machine don’t have TPM chip, and you can also encrypt your external HD and USB’s.
Now I am going to tell you how to use the Bit Locker system.
Go to the control panel.Click on the BitLocker Drive encryption icon.

Health Tips
Evening at 9 - 11pm:
is the time for eliminating unnecessary/ toxic chemicals (detoxification) from the antibody system (lymph nodes). This time duration should be spent by relaxing or listening to music. If during this time a housewife is still in an unrelaxed state such as washing the dishes or monitoring children doing their homework, this will have a negative impact on health.
Evening at 11pm- 1am:
is the detoxification process in the liver, and ideally should be done in a deep sleep state.
Early morning 1 - 3am:
detoxification process in the gall, also ideally done in a deep sleep state.
Early morning 3 - 5am:
detoxification in the lungs. Therefore there will sometimes be a severe cough for cough sufferers during this time. Since the detoxification process had reached the respiratory tract, there is no need to take cough medicine so as not to interfere with toxin removal process.
Morning 5 - 7am:
detoxification in the colon, you should empty your bowel.
Morning 7 - 9am:
absorption of nutrients in the small intestine, you should be having breakfast at this time. Breakfast should be earlier, before 6:30am, for those who are sick. Breakfast before 7:30am is very beneficial to those wanting to stay fit. Those who always skip breakfast, they should change their habits, and it is still better to eat breakfast late until 9 - 10am rather than no meal at all.
Sleeping so late and waking up too late will disrupt the process of removing unnecessary chemicals. Aside from that, midnight to 4:00 am is the time when the bone marrow produces blood. Therefore, have a good sleep and don't sleep late.

THE TOP FIVE CANCER-CAUSING FOODS:
1. Hot dogs
Because they are high in nitrates, the Cancer Prevention Coalition advises that children eat no more than 12 hot dogs a month. If you can't live without hot dogs, buy those made without sodium nitrate.
2. Processed meats and bacon
Also high in the same sodium nitrates found in hot dogs, bacon, and other processed meats raise the risk of heart disease. The saturated fat in bacon also contributes to cancer.
3. Doughnuts
Doughnuts are cancer-causing double trouble. First, they are made with white flour, sugar, and hydrogenated oils, then fried at high temperatures. Doughnuts, says Adams , may be the worst food you can possibly eat to raise your risk of cancer.
4. French fries
Like doughnuts, French fries are ma de with hydrogenated oils and then fried at high temperatures. They also contain cancer- causing acryl amides which occur during the frying process. They should be called cancer fries, not French fries, said Adams ..
5. Chips, crackers, and cookies
All are usually made with white flour and sugar.. Even the ones whose labels claim to be free of trans-fats generally contain small amounts of trans-fats.

BRAIN DAMAGING HABITS
1. No Breakfast
People who do not take breakfast are going to have a lower blood sugar level. This leads to an insufficient supply of nutrients to the brain causing brain degeneration.
2. Overeating
It causes hardening of the brain arteries, leading to a decrease in mental power.
3. Smoking
It causes multiple brain shrinkage and may lead to Alzheimer disease.
4. High Sugar consumption
Too much sugar will interrupt the absorption of proteins and nutrients causing malnutrition and may interfere with brain development.
5. Air Pollution
The brain is the largest oxygen consumer in our body. Inhaling polluted air decreases the supply of oxygen to the brain, bringing about a decrease in brain efficiency.
6. Sleep Deprivation
Sleep allows our brain to rest. Long term deprivation from sleep will accelerate the death of brain cells.
7. Head covered while sleeping
Sleeping with the head covered increases the concentration of carbon dioxide and decrease concentration of oxygen that may lead to brain damaging effects.
8. Working your brain during illness
Working hard or studying with sickness may lead to a decrease in effectiveness of the brain as well as damage the brain.
9. Lacking in stimulating thoughts
Thinking is the best way to train our brain, lacking in brain stimulation thoughts may cause brain shrinkage.
10. Talking Rarely
Intellectual conversations will promote the efficiency of the brain
------------ --------- --------- --------- --------- --------- --------- --------- --------- -------
The main causes of liver damage are:
1. Sleeping too late and waking up too late are main cause.
2. Not urinating in the morning.
3. Too much eating.
4. Skipping breakfast
5. Consuming too much medication.
6. Consuming too much preservatives, additives, food coloring, and artificial sweetener.
7. Consuming unhealthy cooking oil. As much as possible reduce cooking oil use when frying, which includes even the best cooking oils like olive oil. Do not consume fried foods when you are tired, except if the body is very fit.
8. Consuming raw (overly done) foods also add to the burden of liver. Veggies should be eaten raw or cooked 3-5 parts. Fried veggies should be finished in one sitting, do not store.
We should prevent this without necessarily spending more. We just have to adopt a good daily lifestyle and eating habits. Maintaining good eating habits and time condition are very important for our bodies to absorb and get rid of unnecessary chemicals according to "schedule."

Voip voice over ip
Two standards compete for IP telephony signaling. The older and more widely accepted standard is the ITU (International Telecommunication Union) recommendation H.323, which defines a multimedia communications system over packet-switched networks, including IP networks.The other standard, Session Initiation Protocol (SIP), comes from the IETF (Internet Engineering Task Force) working group. Another well established protocol by the name of MGCP (Also comes from the IETF) will be described in details along with the other mentioned protocols.
Voice over IP is a technology for the integration of voice and data in an IP-based network, e.g. LAN, and enables the exchange of voice in real-time in an Internet Protocol based network. Therewith it is possible to unify all means of communication - telephony and messaging - within one user interface in a convergent network. The IP-based network with e.g. LAN or WAN is already available. The VoIP-based PBX replaces or extends the conventional PBX and - like the conventional PBX - controls all the communication processes, e.g. the dial-up. The company does not need a PBX-cabling, spares the PBX-technician, expenses for costly feature-added telephones and for the productive operation. In the fields of Voice over IP, there are mainly two competing standards at the moment: H.323 and SIP.
H.323
H.323, which describes how multimedia communications occur between terminals, network equipment and services, is part of a larger group of ITU recommendations for multi-media interoperability called H.3x. The latest of these recommendations, H.248, is a recommendation to provide a single standard for the control of gateway devices in multi-media packet transmissions to allow calls to connect from a LAN to a Public Switched Telephone Network (PSTN), as well as to other standards-based terminals
The H.323 Architecture
A typical H.323 network is composed of a number of zones interconnected via a WAN. Each zone consists of a single H.323 gatekeeper (GK), a number of H.323 terminal endpoints (TEs), a number of H.323 gateways (GWs), and a number of multipoint control units (MCUs), interconnected via a LAN. A zone can span a number of LANs in different locations, or just a single LAN. The only requirement is that each zone contain exactly one GK, which acts as the administrator of the zone. The functionality of each component of the architecture is defined as follows:
Terminal: An H.323 TE is an endpoint in the network, which provides for real-time two-way communications with another H.323 terminal, GW, or MCU. This communication consists of control, indications, audio, moving color video pictures, and/or data between the two terminals. A terminal may set up a call to another terminal directly or with the help of a GK.
Gatekeeper: The GK is an H.323 entity in the network that provides address translation and controls access to the network for H.323 terminals, GWs, and MCUs. The GK may also provide other services to the terminals, GWs, and MCUs such as bandwidth management and locating GWs. The GK function is optional in H.323 systems.
Gateway: An H.323 GW is an endpoint in the network that provides real-time two-way communications between H.323 TEs on the packet-based network and
Multipoint control unit: The MCU is an endpoint in the network that provides the capability for three or more terminals and GWs to participate in a multipoint conference.
Signaling and Control
H.323 is an umbrella of the following four protocols:
● Registration Admission and Status (RAS): RAS is a transaction-oriented protocol between an H.323 endpoint (usually a TE or GW) and a GK. An endpoint can use RAS to discover a GK, register/unregister with a GK, requesting call admission and bandwidth allocation, and clearing a call. A GK can use RAS for inquiring on the status of an endpoint. There is also a mechanism for GKs to communicate with each other for address resolution across multiple zones. RAS is used only when a GK is present.
● Q.931: Q.931 is the signaling protocol for call setup and teardown between two H.323 TEs and is a variation of the Q.931 protocol defined for PSTN. H.323 adopted Q.931 so that interworking with PSTN/ISDN and related circuit-based multimedia conferencing standards such as H.320 and H.324 can be simplified. H.323 only uses a subset of the Q.931 messages in ISDN and a subset of the information elements (IEs). All the H.323-related parameters are encapsulated in the user-user IE (UUIE) of a Q.931 message.
● H.245: H.245 is used for connection control, allowing two endpoints to negotiate media processing capabilities such as audio/video codecs for each media channel between them. It is a common protocol for all H-series multimedia conferencing standards, including H.310, H.320, and H.324, and contains detailed descriptions of many media types. In the context of H.323, H.245 is used to exchange terminal capability, determine master-slave relationships of endpoints, and open and close logical channels between two endpoints.
● Real-Time Transmission Protocol: RTP is used as the transport protocol for packetized VoIP in H.323. It is adopted directly from IETF and is usually associated with Real-Time Control Protocol (RTCP).
Understanding H.323
The term signaling is used to describe the processes that initiate or terminate a communication session between two parties. If those parties are using the traditional telephone network, the signaling consists of on-hook, off-hook, ringing tones, busy tones, and so on, that communicate the status of one of the parties, or the status of the network.
H.323 endpoints—which could be Terminals, Gateways, Gatekeepers, or Multipoint Control Units—are packet-based, and as such, rely upon signaling messages, instead of signaling tones, to convey required control information to the desired destination. Note that control information is distinguished from data information, as the former is used to supervise and manage the connection between the two endpoints, and must be successfully completed before the data can be sent and received.
The portion of the network under the watchful eye of a Gatekeeper is called a zone, and large networks may have multiple Gatekeepers, and therefore multiple zones. When the Gatekeeper is not present, such as with an IP-phone-to-IP-phone connection, the signaling messages are passed directly between the two endpoints. When the Gatekeeper is present, the endpoints register with the Gatekeeper within their zone upon startup, using a process defined in H.225.0 called RAS, which stands for Registration, Admission and Status. For example, the Registration function occurs when the endpoint sends a Registration Request (RRQ) message to the Gatekeeper, and either a Registration Confirmation (RCF) or a Registration Reject (RRJ) message is returned. Other endpoint messages include the Admission Request (ARQ) asking for admission to the network, Bandwidth Change Request (BRQ), to request a specific amount of network bandwidth.
Once the endpoint has been registered with the Gatekeeper, an H.225.0 call signaling Setup message can be sent to the remote terminal, and H.225.0 Call Proceeding, Alerting, and Connect messages returned. At this point, a connection exists between the calling and called endpoints. Next, the endpoints must exchange their capabilities using the TerminalCapabilitySet [sic] signaling messages defined by the H.245 standard. A very broad set of parameters may be passed with these capability messages. For audio connections, the capabilities include the type of codec (G.711, G.728, G.729, etc.) plus parameters specific to that codec, such as the sampling rate, and the number of audio channels. For data connections, the capabilities include the data protocol in use (such as T.38 for fax or T.120 for whiteboarding applications), plus parameters specific to that data protocol, such as the transmission rate or data compression algorithm to be used. For video connections, the capabilities include the video codec type (such as H.261, H.262 or H.263), and plus parameters specific to that video codec, such as the number of samples per line, lines per frame, and so on. Similar procedures are defined which govern the call disconnection phase, but do not involve as many steps.
Interworking with the PSTN
Even though H.323 was designed for multipoint multimedia conferencing over packet networks, its usage has been primarily driven by VoIP applications, and interworking with the PSTN has been a focus from the very beginning. Unlike SIP, the GW to the PSTN has been an integral part of the H.323 architecture.
Interworking with PSTN usually concerns three call setup scenarios: H.323 TE to phone; phone to H.323 TE; and phone to phone via intermediate H.323 networks. In all cases, an H.323 GW is involved in connecting the PSTN with the Internet. Generally speaking, a GW needs to provide the following functionality.
- PSTN interfaces: This function includes the PSTN signaling interface that terminates signaling protocols such as ISDN Q.931, and the PSTN media interface that terminates media streams such as pulse code modulation (PCM) voice streams.
- VoIP interfaces: This function includes the VoIP signaling interface that terminates H.323 (including RAS, Q.931 and H.245), and the packet media interface that handles RTP.
- Signaling conversion: This function typically translates between ISDN Q.931 signaling and H.323 signaling for call control.
- Media transformation: This function typically translates between the 64 kb/s PCM streams and RTP streams of various speeds.
- Connection management: A major function implied by the above diagram is that a GW must internally coordinate between signaling flows and media transformations. This involves creating, modifying, and deleting the association between the PSTN and Internet flows during the lifetime of a call.
Functional Decomposition
Scalability: As discussed earlier, the bottleneck of scalability for H.323 GWs is media transformation. If we package the MGC and MG in separate boxes and use one MGC to control multiple MGs, we have in effect built a virtual H.323 GW that can handle more lines.
SS7 connectivity: This can be done by connecting the SG function to the SS7 network.
Availability: Decoupling the MGC from the MG increases availability in the sense that multiple MGCs can be used to control a single MG. If one MGC fails, but call states are kept in stable storage, one can apply traditional failover procedures to switch to another MGC. Graceful failover ensures that active calls in the MG s are not lost.
One-stage dialing: This is achieved through support for SS7 connectivity.
