Therapeutic proteins as drug substance may be provided in individual containers prior to the formulation/filling process. To ensure homogeneity, the therapeutic protein may need to be gently mixed in a vessel prior to filling. In this case, mixing may be necessary. Different types of methods utilized for mixing the material may be employed. Examples of mixing techniques include impellers on a shaft with open processing, suspended impellers, or magnetic stir bars at the bottom of the mixing vessel. It is likely that the mixing process will need to be scaled down for testing in the laboratory. Impeller mixing as well as mixing with magnetic stir bars may be simulated at a small scale. The investigator should determine the appropriate mixing speeds that will be utilized in manufacturing and determine if these processes adversely affect the protein. Studies have been reported for therapeutic proteins that have been mixed using magnetic stir bars, and it was demonstrated that this type of mixing may induce aggregates

A general reserve is a reserve, which is created by appropriation of profits. It is created without any specific or particular purpose. When any amount is kept separate by a company out of its profit for future purpose then that is called as general reserves. In other words the general reserves are the retained earnings of a company which are kept aside out of company's profits to meet future (known or unknown) obligations. Reserve is the profit achieved by a company where a certain amount of it is put back into the business which can help the business in their rainy days. The preceding sentence may give the unwary reader the sense that this item is an asset, a debit balance. This is false. A reserve is always a credit balance.

We derived the expression of potential energy in terms of the angle made by the direction of the electric dipole moment and the direction of the external uniform electric field. We found that the potential energy is the negative of the dot product of dipole moment and the electric field.

The potential energy of interaction between dipoles is given by,

V=−4πϵ0​r32P1​P2​​

Here the dipole P1​ is inclined to the dipole P2​ at an angle θ,since the vertical component of P1​ is perpendicular to P2​ is zero i.e. P1​sinθ is zero, taking horizontal component of P1​ along P2​ i.e. P1​cosθ we get

V=−4πϵ0​r32P1​P2​cosθ​

V=−r32kP1​P2​cosθ​..........(since, k=4πϵ0​1​)

Raoult’s law states that a solvent’s partial vapour pressure in a solution (or mixture) is equal or identical to the vapour pressure of the pure solvent multiplied by its mole fraction in the solution.

Mathematically, Raoult’s law equation is written as;

P_solution = Χ_solventP⁰_solvent

Where,

P_solution = vapour pressure of the solution
Χ_solvent  = mole fraction of the solvent
P0_solvent = vapour pressure of the pure solvent

Biomolecules are the most essential organic molecules, which are involved in the maintenance and metabolic processes of living organisms. These non-living molecules are the actual foot-soldiers of the battle of sustenance of life. They range from small molecules such as primary and secondary metabolites and hormones to large macromolecules like proteins, nucleic acids, carbohydrates, lipids etc.

The basic differences between rural and urban settlements are as follows:

 (i) The rural settlements derive their life support or basic economic needs from land based primary economic activities, whereas, urban settlements, depend on processing of raw materials and manufacturing of finished goods on the one hand and a variety of services on the other.

 (ii) Cities act as nodes of economic growth, provide goods and services not only to urban dwellers but also to the people of the rural settlements in their hinterlands in return for food and raw materials. This functional relationship between the urban and rural settlements takes place through transport and communication network.

 (iii) Rural and urban settlements differ in terms of social relationship, attitude and outlook. Rural people are less mobile and therefore, social relations among them are intimate. In urban areas, on the other hand, way of life is complex and fast, and social relations are formal.

Human Settlement is a form of human habitation which ranges from a single dowelling to large city. In other words, it is a process of opening up and settling of a previously uninhabited area by the people. People live in clusters of houses that might be a village, a town or a city. The study of human settlements is basic to human geography because the form of settlement in any particular region reflects human relationship with the environment.

A firm's net value added at FC is distributed as factor income in the form of rent, wages, interest and profit. Sum of rent, interest and profit (i.e., income from property and entrepreneurship) is called operating surplus.
Clearly, operating sulphus is zero :
(i) When loss to the firm is equal to sum of rent, interest and profit. In other words, income generated by the firm is just equal to compensation of employees
(ii) In general government enterprises and non-profit institutions serving households which do not earn income from property and entrepreneurship.

Primary schools were also opened in six villages to teach children. Kasturba taught the ashram rules on personal cleanliness and community sanitation. In order to improve the miserable health conditions Gandhiji got a doctor. He volunteered his services for six months.

Kasturba talked to the women to get rid of their filthy state of clothes. During his long stay at Champaran, Gandhiji taught people self-reliance and freedom from the fear of the British. Thus he paved the path for the freedom of india.

To make sure he had conquered fear, Douglas went to Lake Wentworth in New Hampshire Dived in and swan two miles across the lake to Stamp Act Island. Only once when he was in the middle of the lake, did the terror return. But he confronted it and swam on. He then swam across Warm Lake to the other shore and back .Thus, he was sure of having conquered his fear of water.

Entrepreneurs work under the constraints of their environment – the political economy. Five factors will be key to entrepreneurial success: creativity, tolerance for risk, responsiveness to opportunities, leadership and the ability to take advantage of the rights afforded to you.
