A hem in sewing is a garment finishing method, where the edge of a piece of cloth is folded narrowly and sewn to prevent unravelling of the fabric.
There are many different styles of hems of varying complexities. The most common hem folds up a cut edge, folds it up again, and then sews it down. The style of hemming thus completely encloses the cut edge in cloth, so that it cannot unravel. Other hem styles use fewer folds. One of the simplest hems encloses the edge of cloth with a stitch without any folds at all, using a method called an overcast stitch, although an overcast stitch may be used to finish a folded "plain hem" as well.
There are even hems that do not call for sewing, instead using iron-on materials, netting, plastic clips, or other fasteners. These threadless hems are not common, and are often used only on a temporary basis.
The hem may be sewn down with a line of invisible stitches or blind stitch, or sewn down by a sewing machine. The term hem is also extended to other cloth treatments that prevent unraveling. Hems can be serged (see serger), hand rolled and then sewn down with tiny stitches (still seen as a high-class finish to handkerchiefs), pinked with pinking shears, piped, covered with binding (this is known as a Hong Kong finish), or made with many other inventive treatments.
A hem is a sown edge of cloth. Hem may also refer to:
HEM can stand for:
A hem in knitting is the edge of a piece of knitted fabric that is parallel to the rows of stitches, as compared to a selvage, which is perpendicular to the hem and rows of stitches. Hems can be made in several ways.
The simplest approach is to bind off, possibly with decorative elements such as picots. This approach adds no extra thickness at the hemline (which is sometimes desirable).
Another approach amounts to a tuck: the fabric is folded over and the stitches are knit together pairwise with the stitches of a previous row. In this approach, the fabric is doubled along the hemline.
A reservoir (etymology: from French réservoir a "storehouse" ) is an enlarged natural or artificial lake, storage pond or impoundment created using a dam or lock to store water. Reservoirs can be created by controlling a stream that drains an existing body of water. They can also be constructed in river valleys using a dam. Alternately, a reservoir can be built by excavating flat ground and/or constructing retaining walls and levees.
Tank reservoirs store liquids or gases in storage tanks that may be elevated, at grade level, or buried. Tank reservoirs for water are also called cisterns.
Underground reservoirs store almost exclusively water and petroleum below ground.
A dam constructed in a valley relies on the natural topography to provide most of the basin of the reservoir. Dams are typically located at a narrow part of a valley downstream of a natural basin. The valley sides act as natural walls, with the dam located at the narrowest practical point to provide strength and the lowest cost of construction. In many reservoir construction projects, people have to be moved and re-housed, historical artifacts moved or rare environments relocated. Examples are the temples of Abu Simbel (which were moved before the construction of the Aswan Dam to create Lake Nasser from the Nile in Egypt), the relocation of the village of Capel Celyn during the construction of Llyn Celyn, and the relocation of Borgo San Pietro of Petrella Salto during the construction of Lake Salto.

A petroleum reservoir or oil and gas reservoir is a subsurface pool of hydrocarbons contained in porous or fractured rock formations. The naturally occurring hydrocarbons, such as crude oil or natural gas, are trapped by overlying rock formations with lower permeability. Reservoirs are found using hydrocarbon exploration methods.
Crude oil found in all oil reservoirs formed in the Earth's crust from the remains of once-living things. Crude oil is properly known as petroleum, and is used as fossil fuel. Evidence indicates that millions of years of heat and pressure changed the remains of microscopic plant and animal into oil and natural gas.
Roy Nurmi, an interpretation adviser for Schlumberger, described the process as follows: "Plankton and algae, proteins and the life that's floating in the sea, as it dies, falls to the bottom, and these organisms are going to be the source of our oil and gas. When they're buried with the accumulating sediment and reach an adequate temperature, something above 50 to 70 °C they start to cook. This transformation, this change, changes them into the liquid hydrocarbons that move and migrate, will become our oil and gas reservoir."

Late last night, I missed my train
I walked back to the car and drove home again
Just outside of Pittsburgh, it's really not that far
Saw a light come shining 'cross the reservoir
The sun in California, it drops right into the sea
I took a couple pictures, they don't mean that much to me
Just outside of Pittsburgh, I saw it from my car
The light shines to the bottom of the reservoir
Starless night, come fall around me
Over all we've left undone
I know a light that shines forever
Howsoever we may run
The moon hung on the hillside in eastern Tennessee
With rows of honeysuckle blooming over me
But the iron hills of Pittsburgh where all my memories are
Gathering the light around the reservoir
Starless night, come fall around me
Over all we've left undone
I know a light that shines forever
