Private Sector Health Infrastructure in India : In recent time private sector has been playing a dominant role in health structures as it is clear from the following points:
1. More than 70 percent of the hospitals in India are run by the private sector.
2. They control nearly two fifth of beds available in the hospitals.
3. Nearly 60 percent of dispensaries are run by private sector.
4. Private sector provides healthcare for 80 percent of out-patients and 46 percent of in-patients.
5. It has been playing a dominant role in medical education and training, medical technology and diagnosti

Metal oxide = M0.98O If ‘x’ ions of M are in +3 state, then 3x + (0.98 – x) × 2 = 2 x = 0.04 So the percentage of metal in +3 state would be

The pair of curves (1, 3) and (2, 4) corresponds to different materials but having same intensity of incident radiation. The value of stopping potential for the curves (1, 2) and (3, 4) is same implying that they correspond to similar materials.

The similarity between Li and Mg is because of their similar atomic radii (Li = 152 pm; Mg = 160 pm) and ionic radii. (Li+ = 76 pm,  Mg2+ = 72 pm).These two elements resemble each other in the following properties:(i) Both Li and Mg decompose water very slowly with the liberation of hydrogen.(ii) Both Li and Mg form nitrides  - Li directly and Mg on burning in nitrogen.(iii) LiOH and Mg(OH)2 are weak bases. (iv) Nitrates of both decompose on heating to give oxides.                  (v) Both LiCl and MgCl2 are soluble in ethanol. (vi) Both LiCl and MgCl2 are deliquescent and crystalline from a

Difference between globular protein and fibrous protein:

Fibrous protein


Globular protein
 


1.It is a fibre-like structure formed by the
polypeptide chain. These proteins are held
together by strong hydrogen and disulphide
bonds


1.
The polypeptide chain in this
protein is folded around itself,
giving rise to a spherical
Structure.
 


2. It is usually insoluble in water, but soluble in strong acids and bases.


2. It is usually soluble in water, acids, bases and salts.
 


3. They have comparatively stronger intermolecular forces of attraction.


3. The

(e) (i) The general pattern of settlements is scattered or dispersed.(ii) Large farms are there, but availability of water is less due to which this region has sparse population which is scattered all over in search of water.
(f) The chief form of irrigation is perennial wells. It is necessary because this area gets seasonal rainfall which is not enough for cultivation. Wells are the only source which provide water throughout th
