a) Land Steiner and Wiener

Land Steiner and Wiener discovered Rhesus blood group system.

Shear Modulus is smaller than Young’s Modulus due to the fact that shear stress is not uniformly distributed over the entire cross section of the member while axial stress is generally more uniformly distributed over the cross section. In other words, any member will carry axial stress in a more efficient manner than shear stress.

Exfoliative cytology

Bleeding of Hydraulic brake systems Materials and instruments required: 

1.  Glass jar, fresh hydraulic fluid, flexible plastic pipe of 1/2 meter length which can be fixed to the bleeding nipple. 
2.  Double ended spanner of size 10 mm 
3.  Dry cotton waste. 

Important points 

1 If the bleeding nipple is provided with the master cylinder that should be bled first before proceeding to bleed other wheels. 

2 The sequences of bleeding points for right hand drive vehicle are as follows: 

(a) Master Cylinder (if bleeding nipple provided) 

(b) Left rear wheel 

(c) Right rear wheel 

(d) Left front wheel 

(e) Right front wheel 

(i.e., the farthest wheel from the master cylinder to be bled, after cylinder bleeding and nearest to be bled at last) 

Procedure of bleeding 

(i) Park the vehicle on hard level ground put the hand brake (parking brake) pulled. 

(ii) Start the engine and run it for some line to build up the air pressure if the hydraulic brake system is assisted by compressed air(air assisted hydraulic) 

(iii) Let one person sit on the driver's seat to operate brake pedal and let other person carry out the bleeding operation of different points one by one according to the sequence of mentioned above. 

(iv) Connect the flexible pipe of the bleeding nipple and other end of the pipe should be placed in glass jar to preserve the bled fluid while bleeding air from the system. 

(v) Ask the person who is sitting on the driver's seat to pump the brakes pedal numbers of times till it becomes hard to press but the brakes pedal to be kept in fully pressed position. 

(vi) Loosen the bleeding screw and you will be find air bubbles coming out through bleeding nipple. 

(vii) Number of times same procedure may be repeated till fresh flow of fluid at a pressure coming through the nipple. 

(viii) During every repetition the bleeding nipple should be closed and opened when the signal comes from the driver that he pumped and pressed. 

(ix) After every operation of bleeding, check the level of brake fluid in the reservoir. 

(x) Run the vehicle and check the brake effectiveness.

Fine needle aspiration cytology

Fine needle aspiration cytology includes aspiration done by the pathologist or the clinician as well as guided aspiration done by the radiologists and aspirations. It is a diagnostic procedure used to investigate pathological lesions in organs that do not shed cells spontaneously. In this technique, a thin, hollow needle is inserted into the lesion (usually a lump or a swelling) to obtain cells and tissue fragments, which, after being stained, are examined under a microscope.

The importance of blood grouping: 

1. Safe blood transfusion 

2. Organ transplant especially liver, heart, and kidney 

3. Medicolegal and forensic, paternity disputes 

4. Immunology and genetics

The file can be opened both for input and output operations using fstream class.
The syntax for opening a file with constructor is fstream object(“filename”, mode);
The syntax for opening a file with open() is fstream object.open(“filename”, mode);
Therefore, file can be opened using different modes. They are
ios::in opens file for reading only. For example, fstream fin(“te’xt.dat”, ios::in);
ios::out opens file for writing only. For example, fstream fout(“text.dat”, ios::out);
ios::app opens a file to append to end of file. For example, fstream
file.open(“text.dat”,ios::app);

There are different types of database users. They are
1. Application programmers or Ordinary users:
These users write application programs to interact with the database. Application programs can be written in some programming language typically a SQL statement to DBMS.

2. End Users:
End users are the users, who use the applications developed. They just use the system to get their task done. End users are of two types:

• Direct users
• Indirect users.

3. Database Administrator (DBA):

Database Administrator (DBA) is the person which makes the strategic and policy decisions regarding the data of the enterprise, DBA is responsible for overall control of the system at a technical level.

4. System Analyst:
System Analyst determines the requirement of end-users, and develops specifications for transactions that meet these requirements. System Analyst plays a major role in database design, technical aspect, etc. of the system.

But in 1-chlorobutane, there is no carbon atom which is attached to four different atoms or groups. Hence the chiral compound is 2-chlorobutane.

Correct answer is yesterday

(d) Both statement 1 and 2 are incorrect.

The molar conductivity of KI increases slowly with dilution. Molar conductivity of carbonic acid increases steeply with dilution Therefore, both the statement are false

6 A) traveling

Correct answer is yen

Covalent bond

A covalent bond is formed by equal sharing of electrons from both the participating atoms. The pair of electrons participating in this type of bonding is called shared pair or bonding pair. The covalent bonds are also termed as molecular bonds. Sharing of bonding pairs will ensure that the atoms achieve stability in their outer shell which is similar to the atoms of noble gases.
