RHEL 8 (Red Hat Enterprise Linux 8) is a popular Linux-based operating system used by many organizations for their servers and workstations. In RHEL 8, IP (Internet Protocol) addresses can be set dynamically or statically. A dynamic IP address is assigned automatically by a DHCP (Dynamic Host Configuration Protocol) server, while a static IP address is manually configured by user. In this article, we will discuss three ways to set a static IP address in RHEL 8. Using Network Manager GUI The Network Manager GUI is a graphical user interface that makes it easy to manage network settings, including setting ... Read More
Linux is an incredibly powerful and versatile operating system that is widely used in computing industry. One of most important aspects of using any computer system is ability to manage files and directories. In this article, we will be discussing three ways to permanently and securely delete files and directories in Linux. Why Secure File Deletion is Important When you delete a file or directory from your computer, it does not necessarily mean that data is gone forever. In most cases, data is still present on your hard drive or storage device, but it is marked as "free space" that ... Read More

What is an Infection? In clinical microbiology, to have knowledge of the basics one should learn to know a few very important terms like infection, immunity, disease, etc. The main terms infection and immunity are the effects which are resulted from an interaction between the host and a micro-organism. Infection occurs when organisms find their way into the host body and grow in numbers beyond the level that the immune system is able to defend against. So infection usually occurs when the natural host’s defenses like cilia, intact skin, gastric acid, and the immune system are compromised or overpowered. Infections ... Read More
Introduction Term Germplasm is explained as all the genotypes of a species that could be used for breeding a new genotype. Germplasm conservation is the most effective way for maintaining the genetic traits of endangered and commercially important plants. It must be protected to ensure variability for future species improvement. For plants, germplasm may be stored as pollen, seed, stems, calli, and even a whole plant whereas for animals, genes, and body parts are stored in a gene bank or cryobank. Conventional germplasm is considered as seeds stored at ambient temperature, low temperature, and ultra-low temperatures. But many seeds produce ... Read More
What is Regeneration? Every organism either a plant or an animal has a natural ability to grow and regenerate to a variable extent. This includes an example that every day millions of cells die and for us to survive we need to replace them with new and healthy cells. Similarly, in a plant, if we cut a shoot or its part or perform cloning it will regrow itself. It is due to the meristem cells an organism produces new cells of the same type as well as different types which differentiates to form a specialized tissue, cells, organs, and even ... Read More
Introduction Normally our immune system shows a response towards the foreign antigen and does not act against self-antigens. This phenomenon is known as self-tolerance. It refers to the lack of responsiveness to the individual’s self-antigens. Hence tolerance is antigen-specific. Immune Response Immune tolerance or immunological tolerance is the state of unresponsiveness of the immune system to the substances or tissues that are capable to induce an immune response. It differs from the conventional methods of immune-mediated elimination of foreign antigens. Due to random genetic recombinations, immune cells genetically express receptors for the specific self and foreign antigens in the ... Read More
Introduction Biofilters and Bioscrubbers are the two biotechnology systems that help in controlling air pollution and odor control. Here we use biological organisms for the removal of toxins as the harmful gases and odors caused by the activities of the industries and enterprises pose a great threat to human and environmental health. How Biological Control Systems Take Out the Odor? Typically, all the biological systems use naturally occurring bacteria that feed on odor-producing substances as a food choice. Some of the bacteria are listed below Acidophilus bacteria are primarily used for the removal of H2S odor. Specific bacteria ... Read More
