Rankine cycle is the heart of any thermal power plant. A basic Rankine cycle has four processes, viz. reversible adiabatic work interactions in turbine and pump and isobaric heat interactions in boiler and condenser. A schematic of a thermal power plant is shown in the figure given below. To increase the efficiency of a Rankine cycle Regeneration has been used i.e. bleeding steam to turbine and mixing it with feed water in feed water heater. Different processes in the cycle have to be modelled with the help of data from stream tables. Therefore, it becomes very essential to have ... Read More
Emojis are small digital images or icons that are generally used in messaging and other places to express emotions or ideas. In this article, we are going to see how we can add emojis to an HTML document. Approach By setting the charset used to display webpages in the browser to UTF-8, emojis can be added to HTML documents. We can use the tag in the head section to specify this character encoding information. Emojis can be added to HTML after the charset has been declared by utilising the p and span tags. While the emoji is inserted in ... Read More
HTML, which stands for HyperText Markup Language, is a combination of Hypertext and Markup language which we can use to structure a web page and its content. In this article we are going to take a look at how we can add a description list of an element using HTML. tag The tag is used to represent the description list. This tag is used alongside the tags and . Syntax Description List Content Approach We are going to make use of the tag alongside the and tags to add description list of an ... Read More
Introduction Platelets, also known as thrombocytes, are small, colourless, disc-shaped cells that play a crucial role in haemostasis, a process by which bleeding is stopped in injured blood vessels. Platelets are produced in the bone marrow and circulate in the blood until they are needed to form a blood clot. The clotting process involves a complex interplay between platelets, coagulation factors, and blood vessel walls. Platelet Structure and Function Platelets are the smallest of the three types of blood cells, with an average size of 2-3 µm in diameter. They are produced by megakaryocytes in the bone marrow, which ... Read More
HTML5 is a combination of technologies that the user can use for creating more robust and diverse websites and web apps that support multimedia, and communicate with software interfaces, among other things. In this article, we are going to see how we can add controls to audio in HTML5. Syntax The controls attribute of the tag can be used to specify the controls of the embedded audio. It allows the user to technically embed a music player directly in the webpage. The controls attribute adds functionalities such as play, pause, and volume. ... Read More
HTML, which stands for HyperText Markup Language, is a combination of Hypertext and Markup language which we can use to structure a web page and its content. This article will show how we can add a color picker using HTML. Syntax For Output Code pre class The tag is an interactive element in HTML whose main purpose is to take different forms of inputs from the user. The tag's type attribute specifies what kind of input the user should enter. Approach We are going to make use of the tag. To accomplish the task, we are going ... Read More
CSS, the acronym for cascading style sheets, is a straightforwardly built language that makes it easier to present web pages. Applying styles to web pages is possible with CSS. In this article we are going to see how we can use CSS to add an image as the list-item marker in a list. Approach We are going to make use of the list-style-image property to accomplish the task. The list-style-image property allows the user to set an image as the list-item marker in a list. Syntax list-style-image: none | url | initial | inherit; Example Step 1 − First ... Read More
Introduction Megakaryocytes are large cells found in the bone marrow that are responsible for producing platelets, which are essential for blood clotting. They are named for their large size, with a diameter ranging from 30 to 100 micrometers, and are classified as a type of hematopoietic cell, meaning they originate from stem cells in the bone marrow. Megakaryocytes are large, multinucleated cells that are responsible for producing platelets, which are essential for coagulation of blood. They are unique among bone marrow cells due to their enormous size, and their ability to undergo endomitosis, where they replicate their DNA without cell ... Read More
Introduction Blood is a vital component of the human body, transporting oxygen and nutrients throughout the body and removing waste products. It is a complex mixture of different types of cells and plasma, which work together to maintain homeostasis. White blood cells, also known as leukocytes, play a crucial role in the body’s immune system. They help defend the body against infections and other foreign invaders. One of the types of leukocytes is the myelocyte. It is a cell of the granulocytic series and is one of the stages of the maturation of neutrophils. Myelocytes are a critical part ... Read More
Introduction The Major Histocompatibility Complex (MHC) is a group of genes that encode for cell-surface proteins involved in antigen presentation to the immune system. These proteins are classified into two groups: MHC class I and MHC class II. MHC class II molecules are found primarily on antigen-presenting cells (APCs), such as dendritic cells, macrophages, and B cells. They play a critical role in initiating and regulating adaptive immune responses by presenting exogenous antigens to CD4+ T cells. Structure of MHC class II Molecules MHC class II molecules are heterodimers consisting of two chains: alpha and beta. The alpha ... Read More
