Herbicides are a class of pesticides formulated to kill or restrict the growth of weeds that have a negative impact on crop nutrition and growth. They can also be synthesized from natural sources, and these herbicides are commonly known as bio-herbicides. An increase in the global demand for food has led to increased pressure on farmers to enhance crop yield. Hence, herbicides are being increasingly adopted to meet the demands. The major type of herbicides used is glyphosate-based herbicides. Herbicides are also used for non-crop applications such as turf and ornamental management.

Mini excavators, commonly known as compact excavators, are tracked or wheeled vehicles. They weigh approximately 0.7 to 8.5 tons, and are unique compared to other excavators. Due to their small size, mini excavators can fit through doorways and can be used to carry out work at mining sites. Also, mini excavators can be easily craned anywhere or can be transported by an average truck with a trailer hitch. Mini excavators come with huge benefits. One of the major benefits of the equipment is its easy transportation from one site to another. In addition, it has various other attachments that can be used for drilling holes, digging trenches, and breaking rock.

Radar is an object detection system that makes use of radio waves to ascertain the range altitude, direction, and speed of approaching and still objects. It is used to detect missiles, spacecraft, ships, aircraft, weather formations, and terrain. It is used as an early-warning device to spot an enemy's airborne systems and approaching missiles from great distances, and for surveillance, ground control interceptions, and long-range early warnings. It is mainly used by defense establishments.

Elevators are a type of transport system that facilitate the vertical transit of people and goods within a building's premises. Escalators are moving staircases that are mainly used for transporting people between the different floors of buildings. People depend on elevators and escalators in various places such as airports, office buildings, malls, residential complexes, schools, and railway stations.

miRNAs are single-stranded, small, non-coding RNA molecules that regulate gene expression at the translation level. They play a vital role in research, diagnostics, and therapeutics to study expression of genes and to control diseases by gene silencing. They interact with mRNA molecules and regulate expression of genes by mRNA cleavage, translational repression, and deadenylation. They are generally 17-27 nucleotides long and regulate post-transcriptional mRNA expression by binding to the 3’ untranslated region of the mRNA sequence, which results in translational suppression and gene silencing. miRNAs are involved in a wide range of biological processes, including apoptosis, cell cycle control, and several developmental processes such as stem cell differentiation, hypoxia, hematopoiesis, neurogenesis, insulin secretion, cardiac and skeletal muscle development, aging, cholesterol metabolism, viral replication, and immune responses. They can be used as therapeutics for the treatment of some severe diseases including cancer and genetic disorders by introducing specific miRNAs into diseased cells to silence the defective gene.

Antisense and RNAi therapeutics are new innovative therapeutic options that can be used for the treatment of serious chronic and rare diseases. RNAi is an RNA-based gene silencing process in which RNA molecules inhibit gene expression by destroying specific mRNA molecules. Antisense technology involves the synthesis of a strand of nucleic acid that would bind to the disease-causing mRNA. It binds to the mRNA or to a splicing site on the pre-mRNA and inactivates it effectively. RNAi and antisense are two of the predominant technologies used by pharmaceutical companies, research institutes, and others for various applications in research, diagnostics, and therapeutics. RNAi therapeutics offers a wide scope in the treatment of diseases such as cancer and neurodegenerative diseases. Two types of RNA molecules are used in RNAi technology: miRNA and siRNA. RNAi molecules bind to other specific RNAs in the cell, such as mRNA, to manage their activity to treat the RNA-mediated disorder.

Brazing is defined as the process of joining two metals by deploying a filler metal such as a brazing alloy. In the brazing process, the filler metal is heated to slightly above its melting point and allowed to flow through capillary action between the two base metals that need to be joined. This process is normally undertaken by using a controlled atmosphere called a flux. The flux is used to prevent, dissolve, or remove oxides that are formed during the brazing process. Brazing is similar to soldering, except that the melting point of the filler metal used in brazing is above 842 degrees fahrenheit while the melting point of that used in soldering is below 450 degrees centigrade.

Biofertilizers are made from human, animal, and organic wastes and are natural and sustainable in nature. Biofertilizers contain microorganisms such as bacteria, algae, and fungi, alone, or in combination, and they enhance nutrient availability in plants. The benefits of biofertilizers include improved crop yields and soil fertility, and they also revive the soil quality. Biofertilizers can be broadly classified as nitrogen fixing, phosphate solubilizing, and others, including potash mobilizing and zinc mobilizing based on product type.

Packaging, in broad terms, refers to the technology of enclosing a product for the purpose of storage, distribution, sale, and use. Containers, in general terms, refer to a package, wrapper, or receptacle in which a product is offered for sale. It does not include shipping containers, package liners, or any large outer wrapping that is not provided for the consumer. Container and packaging products can be manufactured using a number of raw materials such as metal, plastic, paper, glass, and fiber. The Global Container and Packaging market comprises products manufactured for packaging purposes used by numerous sectors including Food, Beverages, Healthcare, Toiletries, Personal Care, and others.

Shoulder-fired weapons, classified as anti-tank or anti-aircraft, use a launcher to fire a warhead at a target. The projectile fired includes guided as well as unguided missiles and grenades. Unlike other missile systems, which tend to be bulky and require operational expertise, shoulder-fired weapons are small enough to be carried by a single person and can be operated easily without much training.
