The expression depicting the powers to which the fundamental units are to be raised to obtain one unit of a derived quantity is known as the dimensional formula. It is given as, Q = MaLbTc, where, M, L, T are base dimensions with respective exponents a, b and, c. and Q is the ph...
What Are EMFs? EMFs are Electromagnetic Fields. They are also known as Electromagnetic Radiation (EMR). There are four main types of EMFs. Let’s take a brief look at these in more detail. Radio Frequency Radiation (RF).RF is the higher frequency radiation created by cell phones, wi-fi,...
What is a bad EMF reading? Summary: Electric field readings within living spaces above 10 V/m (Volts per meter) are considered high. ... Since this is a less talked about form of EMF radiation, there is less information about it, but I want to summarize the reason I concluded that am...
The study of social behavior of human cells has shown that cells are not simply independent units, but that they interact with each other in complex ways. They release a chemical called cytokines to signal changes in behavior like dividing, migrating, or dying. Cells also communicate through dir...

Today, the concept of the circular economy (CE) has different meanings for various scholars. There are numerous definitions that focus on highlighting different aspects and principles of CE. However, there has been little effort made regarding the focus of CE definitions on various environmental aspe...
Practical Measurement: To measure voltage, instruments like voltmeters or multimeters are used, connected in parallel with the circuit element to assess the potential difference accurately. What is Voltage? Voltage (also known as electric potential difference, electromotive force emf, electric pressure, ...
