The Council of Scientific and Industrial Research (CSIR) has entrusted the responsibility of conducting CSIR-UGC NET in CBT mode to NTA. CSIR-UGC NET is a test being conducted to determine the eligibility ‘for Junior Research Fellowship (JRF) and for Lectureship/Assistant Professor’ in Indian universities and colleges subject to fulfilling the eligibility criteria laid down by UGC. Online applications for JRF/NET are invited twice a year on all India basis through Press Notification of CSIR-UGC NET for JRF and LS/AP.

CSIR and UGC provide Research Fellowships for training in methods of research under the expert guidance of faculty members/scientists working in the University Department/ National Laboratories and Institutions in various fields of Science. CSIR-UGC NET Fellowships are tenable in Universities/IITs/Post Graduate Colleges/Govt. Research Establishments including those of the CSIR, Research & Development establishments of recognized public or private sector industrial firms and other recognized institutions. Only bonafide Indian citizens are eligible for the test. CSIR-UGC NET Fellowship is tenable in India. The program is aimed at the National Science & Technology Human Resource Development.

**Partial Differential Equation:**

PDEs can be used to describe a wide variety of phenomena such as sound, heat, electrostatics, electrodynamics, fluid dynamics, elasticity, or quantum mechanics. These seemingly distinct physical phenomena can be formalized similarly in terms of PDEs. Free download PDF Basic Concepts Of Differential Equations Hand Written Note By Praveen Chhikara.

Just as ordinary differential equations often model one-dimensional dynamical systems, partial differential equations often model multidimensional systems. PDEs find their generalization in stochastic partial differential equations. Free download PDF Basic Concepts Of Differential Equations Hand Written Note By Praveen Chhikara.

PDEs are used to formulate problems involving functions of several variables, and are either solved by hand or used to create a relevant computer model. A special case is ordinary differential equations (ODEs), which deal with functions of a single variable and their derivatives.

In mathematics, a partial differential equation (PDE) is a differential equation that contains unknown multivariable functions and their partial derivatives. Free download PDF Basic Concepts Of Differential Equations Hand Written Note By Praveen Chhikara.

**Ordinary Differential Equation:**

In mathematics, an ordinary differential equation (ODE) is a differential equation containing one or more functions of one independent variable and its derivatives. The term ordinary is used in contrast with the term partial differential equation which may be with respect to more than one independent variable.

Among ordinary differential equations, linear differential equations play a prominent role for several reasons. Most elementary and special functions that are encountered in physics and applied mathematics are solutions of linear differential equations (see Holonomic function). When physical phenomena are modeled with non-linear equations, they are generally approximated by linear differential equations for an easier solution. The few non-linear ODEs that can be solved explicitly are generally solved by transforming the equation into an equivalent linear ODE (see, for example, Riccati equation).

Some ODEs may be solved explicitly in terms of known functions and integrals. When it is not possible, one may often use the equation for computing the Taylor series of the solutions. For applied problems, one generally uses numerical methods for ordinary differential equations for getting an approximation of the desired solution.

The CSIR conducts the UGC-CSIR NET for other Science subjects, to be specific, Life Sciences, Physical Sciences, Chemical Sciences, Mathematical Sciences, and Earth Atmospheric Ocean and Planetary Sciences mutually with the University Grants Commission. The tests are directed twice in a year for the most part in the months of June and December.

**CSIR NET Exam Pattern 2020:**

NTA has released the CSIR NET Exam Pattern for all the five subjects. Candidates will have to pick any one subject and apply for the same. The CSIR UGC NET exam pattern and marking scheme are different for all the subjects.

- CSIR NET question paper for each subject is divided into three parts namely, Part A, Part B, Part C.
- All three sections are compulsory.
- There will be no break between the three sections.
- All 3 parts will have only Multiple Choice Questions (MCQs).
- The CSIR NET 2020 will be conducted for a total of 200 marks.
- The exam will be held for a duration of 3 hours.
