Mesh consists of semi-permeable barrier made of connected strands of metal, fiber, or other flexible/ductile material. Mesh is similar to web or net in that it has many attached or woven strands.

Types of mesh [link]
- A plastic mesh is extruded, oriented, expanded or tubular. Plastic mesh can be made from polypropylene, polyethylene, nylon, PVC or PTFE.
- A metal mesh can be woven, knitted, welded, expanded, photo-chemically etched or electroformed (screen filter) from steel or other metals.
- In clothing, a mesh is often defined as a loosely woven or knitted fabric that has a large number of closely spaced holes, frequently used for modern sports jerseys and other clothing.
- A mesh skin graft is a skin patch that has been cut systematically to create a mesh. Meshing of skin grafts provides coverage of a greater surface area at the recipient site, and also allows for the egress of serous or sanguinous fluid. However, it results in a rather pebbled appearance upon healing that may ultimately look less aesthetically pleasing.[1]
Uses of meshes [link]
- Meshes are often used to screen out unwanted things, such as insects. Wire screens on windows and mosquito netting can be considered as types of meshes.
- Wire screens can be used to shield against radio frequency radiation, e.g. in microwave ovens and Faraday cages.
- Metal and nylon wire mesh filters are used in filtration
- Wire mesh is used in guarding for secure areas and as protection in the form of vandal screens.
- Wire mesh can be fabricated to produce park benches, waste baskets and other baskets for material handling.
- A huge quantity of mesh is being used for screen printing work.
- Surgical mesh is used to provide a reinforcing structure in surgical procedures like inguinal hernioplasty, and umbilical hernia repair.
- Meshes are also used as drum heads in practice and electronic drum sets.

Partition of an interval
In mathematics, a partition of an interval [a, b] on the real line is a finite sequence x = ( xi ) of real numbers such that
In other terms, a partition of a compact interval I is a strictly increasing sequence of numbers (belonging to the interval I itself) starting from the initial point of I and arriving at the final point of I.
Every interval of the form [xi, xi+1] is referred to as a sub-interval of the partition x.
Refinement of a partition
Another partition of the given interval, Q, is defined as a refinement of the partition, P, when it contains all the points of P and possibly some other points as well; the partition Q is said to be “finer” than P. Given two partitions, P and Q, one can always form their common refinement, denoted P ∨ Q, which consists of all the points of P and Q, re-numbered in order.
Norm of a partition
The norm (or mesh) of the partition
is the length of the longest of these subintervals, that is
Applications
Partitions are used in the theory of the Riemann integral, the Riemann–Stieltjes integral and the regulated integral. Specifically, as finer partitions of a given interval are considered, their mesh approaches zero and the Riemann sum based on a given partition approaches the Riemann integral.
