Liquefaction of Gases – Critical Phenomenon A gas can be liquefied by lowering the temperature and increasing the pressure. At lower temperature, the gas molecules lose kinetic energy. The slow moving molecules then aggregate due to intermolecular attractions between them and are converted into liquid. The increase of pressure - The gas molecules come closer by compression and coalesce to form the liquid.

A view of chemical bonding in which bonds arise from the overlap of atomic orbitals on two atoms to give a bonding orbital of electrons localized between the bonded atoms. Basic Principle: A covalent bond forms when the orbitals of two atoms overlap and the overlap region, which is between the nuclei, is occupied by a pair of electrons.

A normal P-N junction diode is usually fabricated by adjusting the P-type and N-type semiconductors on a single semiconductor crystal. The characteristics of a junction diode demonstrate that it is designed largely for operating in the forward direction. Applying a large amount of forward bias causes greater forward current with a small value of forward voltage.

Programming is the art of writing computer instructions in a language that the computer can interpret and/or understand. In this topic, we shall look at some basic definitions and introduce some basic concepts in programming. Definition 1. A computer is an electronic machine that accepts data as its input, process these data based on some instructions to produce information as it output. These instructions that guide a computer on how to process the data is what we refer to as a program.

Client/Server is a term used to describe a computing model for the development of computerized systems. This model is based on the distribution of functions between two types of independent and autonomous processors: servers and clients. A client is any process that requests specific services from server processes.

HIV-Human Immune Virus This is a virus that causes AIDS and is passed from person to person through body fluids, particularly blood, semen and breast milk .After a person has been infected, the virus starts breaking down their immune system .After sometime the immune system is so weak that they become susceptive to a variety of illness

Concurrent access to shared data may result in data inconsistency. Maintaining data consistency requires mechanisms to ensure the orderly execution of cooperating processes. Suppose that we wanted to provide a solution to the consumer-producer problem that fills all the buffers.

CPU is always busy in Multiprogramming. Because CPU switches from one job to another job. But in simple computers CPU sit idle until the I/O request granted. Scheduling is an important OS function. All resources are scheduled before use.(cpu, memory, devices…..) Process scheduling is an essential part of a Multiprogramming operating systems. Such operating systems allow more than one process to be loaded into the executable memory at a time and the loaded process shares the CPU using time multiplexing

Counseling is a professional relationship between two or more people, one of whom is a trained counselor, and the other(s), a person or persons undergoing therapy. The relationship is aimed at helping the counselee identify his/her own strength and use it to solve their problems. Counselling refers to the skilled and principled use of relationships (rapport) to facilitate self–knowledge, emotional acceptance, growth and the optimal (maximum) development of personal resource.

State the purposes served by clippers, clampers, and voltage multipliers. Describe the operation of series and shunt clippers. Describe the effects of negative and positive clampers on an input waveform. Describe the use of the LED in multisegment displays. Study simple diode logic circuits.

Digital technology pervades almost everything in our daily lives. For example, cell phones and other types of wireless communications, television, radio, process controls, automotive electronics, consumer electronics, aircraft navigation— to name only a few applications— depend heavily on digital electronics.

Microbiology is the study of small living organisms (things) that cannot be seen with our naked eyes but with a help of a Microscope e.g.: Viruses, Bacteria Fungi, Algae, Protozoans etc. Microorganisms are those living things that are too small to be seen with the naked eye

Parasitology is the science that deals with organisms living in the human body (the host) and the medical significance of this host-parasite relationship. A Parasite is a living organism, which takes its nourishment and other needs from a host; the host is an organism which supports the parasite.

Port sanitation is the work carried out by all designated port health authorities in the world towards the control of spread of quarantinable diseases. The essential aim is to ensure the maximum security against the international spread of the disease with the minimal interference with world traffic

Brief notes on calculus I which are upto date

This course covers key areas in syntax and morphology from a theoretical perspective. In syntax, two approaches have been adopted: the formal and the functional. Issues in morphology are handled within generative grammar. However, as an entry point into the course, we begin by asking some basic questions about the study of language. Some of them you have encountered before but they appear here for recapping purposes.

Comparative education is a discipline within the field of education. Its main purpose is to enlighten the teacher trainee on issues of educational systems in other countries with a view of broadening their perspective on educational problems and attempted solution.

Comparative education is a fully established academic field of study that examines education in one country (or group of countries) by using data and insights drawn from the practices and situation in another country, or countries. Programs and courses in comparative education are offered in many universities throughout the world, and relevant studies are regularly published in scholarly journals such as Comparative Education, International Review of Education, International Journal of Educational Development, and Comparative Education Review. The field of comparative education is supported by many projects associated with UNESCO and the national education ministries of various nations.
