Out for humanity!!!!!
Well it finally got started!I was not expecting it, but thanks to mother and my close relative who made it possible. About a month had passed in fun and very little work. And another month lay ahead of me with no idea of what to do.
It was not about 30 hour voluntary service you need for Duke of Edinburgh award, i already was done with that. It was about getting out of house and doing something, to learn, to help, to serve humanity voluntarily. But i was like a blind who needed some help! And so i got the help and crossed the wide gap ready for the task with eyes bestowed once again!
My social service was to be in civil hospital, it was my first day, all the things which some well known and other people had instructed me were in my mind. I reached there half an hour earlier. So had to wait for that time and a further 1 hour for waiting the person who would tell me the work, Mr.Sajid. He didn't come but fortunately i found my uncle there(working as a senior assistant prof.), he supervised me to the Dowites78 operation theatre or O.T as we call it.
I went inside the first operation theatre or lobby where i had to meet Dr.Riffat, an anaesthesiologist.
A patient was lying on the bed and the doctor was trying something with some apparatus which later the doctor told me was anaesthetic machine when i asked her. I continued to watch the things carefully and understand the procedures. The operation started, firstly reluctant, i later had the courage to watch the surgery, i saw the tools and some of the techniques. During operation the doctor called me and told me about the gigantic anaesthetic machine that was of multi-purpose. Operation lasted for more than 3 hours.
I came back down where i met him and told him about my activities. I headed back towards my home quite happy because a good 1st day and a plan of learning more next day!!!

Learn IV canulation__ for pre-medical students
1. Assemble all the equipment required:
Gloves
Sharps bin
2. Prime 3 way tap and extension with saline:
3. Explain to the patient what you intend to do and why. Obtain verbal consent.
4. Tighten a tourniquet around he appropriate limb and identify an appropriate vein:
5. Clean the insertion site with the alcohol wipe:
6. Infiltrate the insertion site with local anaesthetic:
7. Hold the cannula so that you will be able to see blood entering the transparent flashback chamber. Keep the bevel facing upwards. Stretch the skin with the thumb of your non-dominant hand.
8. Insert the cannula, aiming for the vein, until you get a flashback of blood
9. Insert the cannula slightly further - remember that the plastic sleeve of the cannula does not extend right to the tip of the trocar:
10. Hold the trocar still with your dominant hand and slide the plastic cannula forward with your other hand
11. Compress the vein over the tip of the cannula to prevent blood entering the cannula, withdraw the trocar and dispose of it immediately in the sharps bin.
12. Continue to compress the vein and connect the extension tubing
13. Secure the cannula in place with a transparent adhesive dressing

Its fun time!
Taking your time out for some fun is indispensable. It’s the time of physical activity rather than bogging up of your mind in work.
Fun can be of any sort, playing football, cricket, badminton, going for swimming or outing with the friends or family members, the latter most possible in the holidays. It’s the ultimate fun time when we move on to the water parks, voluminous clubs, parks and to the beach points.
So we decided and went to Shaheed Nisar park mainly because of my aunt who insisted on going there. Now searching for the destination was another story! We wandered in the defense area of our city (Karachi) for about half an hour following my aunt car and than we got stuck in a traffic signal & our aunt got out of our sight, my elder brother called her trying to ask where they were, but all to no use, we took several wrong cuts, after that I decided to move to the park by myself taking help from the some people who were moving about the road. Finally I was successful! Me and my family reached before my aunt and for that I teased her when she came a little later.
I entered the park with all other people with me. It quite nice park with wide jogging tracks, clean grass fields, games for kids and playing area for us. I can say that we did enjoy there especially because my family and cousins were there and the delicious cuisines we ate in the end.
We retuned home very tired yet happy!

Mathematics important points__For P-1(A-levels)
Bear in mind that these just highlight important points or the points i thought to be important for math __P-1. Before going through these be confident that you are already prepared. In addition these points will help you in achieving better marks in exam papers. These points also cover some of the points sometimes we just ignore but are important. If you feel any complications while going through please let me know.
1)1, 2, 3,……. are natural numbers.
2).....,-1, 0, 1, 2,…. Are integers.
3)Rational and irrational numbers constitute real numbers.
4)Surds___ numbers in root form…(cube root, square root)
5)Rationalizing surd__ Removing surd from denominator
6)Range__f(x), domain__ values of x.
7)Modulus__[x]=x or [x]= -x
8)If (b^2) - 4ac >0_____ it will have two real roots
9)If (b^2) - 4ac <0_____>
10)If (b^2) - 4ac =0_____it will have equal roots or one root only.
11)Division or multiplication of an inequality by negative number changes the sign.(- to + or vice versa)
12)tan (angle)= gradient of a line, subtract the gradient of the given 2 lines and use formula to find the angle between the two lines.
13)For arithmetic progression, Sn=0.5n(a+l) or Sn=0.5n(2a+(n-1)d)
14)For geometric progression, Sn=a(1-r^n)/1-r and sum to infinity=a/1-r
15)Infinite geometric series is said to be convergent if [r]<1.
16)Note surface area and volume of cylinder, sphere, cone, pyramid and prism. These are important….. You must remember them.
17)Term independent of x__ take x^0

The board exams ends with the beggining of our long vacations. And like me people make dizzying plans which remain a mere thought! " I will read the books for the new session, i will give SAT test, i will join some club, i will go on for trips with my friends........and something interactive!" And by the end of the vacations we have hardly done any of the tasks!
I too had the same problem!But now i have got a resolution.Firstly we need to know what summer vacations are for? They are for studying to be prepared for the next session? joining coaching centres?or to give some rest to people in intense heat of june& july? I might say yes to all the questions but i would qualify my statement by stating that we need to plan our vacations carefully instead of wavering & trying to do all the things, this is almost impossible!Choose any single thing and plan in a way that you have almost a month free. Even if you do single thing, the real pleasure is when you do it complete! Believe me never think you are short of tasks, always remember you have a month extra and it is when you can do as many things as you wish!
Although i never did what i ve discovered, this vacations am doing the same and with this planning i hope it would turn out to be the best vacations ever!
Important definitions and formulas for Physics_AS
These are extremely important points which you must know. These all points will be covered in two posts. Note them.
1)SI unit_ a system of units internationally accepted.
2)Base unit_ units for basic physical quantities.
3)Dimensions_relationship between physical and derived quantities.
4)Unit for young modulus_kgm^-1s^-2.
5)Reading_ single determination of the value of an unknown quantity.
6)Measurement_ Final result of analysis of series of readings.
7)Moment of force_ turning effect of force or torque.
8)Couple_ consists of two forces acting on an object of same magnitude but not in the same line.
9)Centre of gravity_ where the weight of an object is assumed to act.
10)One Newton_ It is defined as a force when which acts of a body of mass, m, produces an acceleration of 1m/s.
11)Formula for pressure on the wall_ P=pv^2, (p=density)
12)Work done = Fs cos0 (0= theta).
13)One joule_ it’s the work done by a force of 1 newton when its point of application is displaced a distance of 1m in direction of force.Next post covering other points will be published shortly on the blog.

More definitions for physics_AS
These are probably the points I noted down and memorized them. They are good for revision.
1) Work done by a gas_ W= pressure * change in volume
2) Power_ force*velocity (very important)
3) One watt_ one watt is the power expended when 1 joule of work is done in 1 second.
4) Elasticity_ It’s the property of the body which enables the body to regain its position when the deforming force is removed.
5) Transverse waves_ The motion of oscillation is perpendicular to the wave motion.
6) Polarization_ The oscillations are made to move in single plane only.
7) Interference of waves_ It’s the effect produced by the superposition of two coherent waves passing through the same region.
8) Intensity_ It’s the rate at which energy is transferred by the wave to the unit area which is perpendicular to the direction of the propagation of wave. Point to be noted__ Intensity is directly proportional to the Square of frequency and Square of amplitude.
9) Potential difference_ P.d between the two points is the energy dissipated when 1 coloumb of charge flows from one point to another.
10) Electromotive force_ It’s the energy supplied from source to each coloumb charge to drive the charge round the complete circuit.
11) Ohm_ It’s the resistance of the conductor if when a current of 1A flows through it, the voltage across it is 1 volt.
12) Kirchhoff’s 1st law_ The algebraic sum of currents entering a junction in a circuit is zero.
13) Kirchhoff’s 2nd law_ Round a closed loop the algebraic sum of E.M.Fs is equal to the algebraic sum of the products of current & resistance.This post & the previous one almost cover all the definitions important for exams.
