`` But you want to ask me when B'dikkat is going to come back with the needle ''.

In September of 1820, Ampère ’ s friend and eventual eulogist François Arago showed the members of the French Academy of Sciences the surprising discovery of Danish physicist Hans Christian Ørsted that a magnetic needle is deflected by an adjacent electric current.

To conduct an atom probe experiment, such a needle is placed in an ultra high vacuum chamber.

Beadwork is the art or craft of attaching beads to one another or to cloth, usually by the use of a needle and thread or soft, flexible wire.

The needle is passed back through the beads above the warp threads to lock the beads into place.

The design of this example is closely based on Flemish needle lace of the 17th century.

Though this is true when comparing a single crochet swatch with a stockinette swatch, both made with the same size yarn and needle / hook, it is not necessarily true for crochet in general.

Turntablism embodies the art of cutting, beat juggling, scratching, needle drops, phase shifting, back spinning, and more to perform the transitions and overdubs of samples in a more creative manner ( although turntablism is often considered a use of the turntable as a musical instrument rather than a tool for blending recorded music ).

Embroidery is the art or handicraft of decorating fabric or other materials with needle and thread or yarn.

Saline is infused under pressure into the corpus cavernosum with a butterfly needle, and the flow rate needed to maintain an erection indicates the degree of venous leakage.

The use of needle exchange programs in areas with a high density of drug users with HIV is an example of the successful implementation of this treatment method.

The infusion set is a thin plastic tube with a fine needle at the end.

By contrast, the left-plaited stitch is generally formed by hand-knitters by wrapping the yarn in the opposite way, rather than by any change in the needle.

The loops on the metal needle are the active stitches, and the yarn coming out of the knitting on the right is the working yarn.

Needle felting is a technique used to add decoration to a knitted or felted piece, where raw roving is applied using a very sharp barbed felting needle by repeatedly piercing the roving and background together.

Adding a " slip stitch " ( where a loop is passed from one needle to the other ) allows for a wide range of textures, including heel and linen stitches, and a number of more complicated patterns.

Changing the order of stitches from one row to the next, usually with the help of a cable needle or stitch holder, is key to cable knitting, producing an endless variety of cables, honeycombs, ropes, and Aran sweater patterning.

There are various method employed to " cast on ," such as the " thumb method " ( also known as " slingshot " or " long-tail " cast-ons ), where the stitches are created by a series of loops that will, when knitted, give a very loose edge ideal for " picking up stitches " and knitting a border ; the " double needle method " ( also known as " knit-on " or " cable cast-on "), whereby each loop placed on the needle is then " knitted on ," which produces a firmer edge ideal on its own as a border ; and many more.

However, large gauge needles emphasise those actions and knitting becomes increasingly more awkward when the needle diameter is greater than the width of the knitters finger.

The hook catches the loop of yarn as each stitch is knitted, meaning that wrists and fingers don ’ t have to work so hard and there is less chance of stitches slipping off the needle.

Originally the instruments relied on the Earth's magnetic field to provide the restoring force for the compass needle ; these were called " tangent " galvanometers and had to be oriented before use.

Such effects occur when light is reflected off the " silk " ( the structurally oriented rutile needle inclusions ) in a certain way.

Passing a small compass over the terrella, Gilbert demonstrated that a horizontal compass would point towards the magnetic pole, while a dip needle, balanced on a horizontal axis perpendicular to the magnetic one, indicated the proper " magnetic inclination " between the magnetic force and the horizontal direction.

The use of the compass means that the needle was directed towards the actual magnetic pole at the time of construction, or last reconstruction, of the respective tomb.

In flight, the ADF's RMI or direction indicator will always point to the broadcast station regardless of aircraft heading, however a banked attitude can have a slight effect on the reading, the needle will still generally indicate towards the beacon, however it suffers from DIP error where the needle dips down in the direction of the turn.

The direction of the needle in the femoral artery can be against blood flow ( retro-grade ), for intervention and diagnostic towards the heart and opposite leg, or with the flow ( ante-grade or ipsi-lateral ) for diagnostics and intervention on the same leg.

Alternatively, if the track takes the flight directly overhead a beacon, the pilot can use the ADF instrument to maintain heading relative to the beacon, though " following the needle " is bad practice, especially in the presence of a strong cross wind-the pilot's actual track will spiral in towards the beacon, not what was intended.

* Electrical effect: electrical storms, and sometimes also electrical interference ( from a ground-based source or from a source within the aircraft ) can cause the ADF needle to deflect towards the electrical source

Police also reported being anxious about accidental needle sticks and acquiring communicable diseases from IDUs, but were not trained or equipped to deal with this occupational risk ; this anxiety was intertwined with negative attitudes towards syringe access initiatives.

Since the arachnoid membrane and the dura mater exist in flush contact with one another in the living person's spine ( due to fluid pressure from CSF in the subarachnoid space pushing the arachnoid membrane out towards the dura ), once the needle has pierced the dura mater it has also traversed the thinner arachnoid membrane and is now in the subarachnoid space.

For example, a regular rate of response would cause the needle to move vertically at a regular rate, resulting in a straight diagonal line rising towards the right.

* If you find a needle and it is pointing towards you, you will have bad luck ; if it pointing away from you, you will have good luck.

Georg Hartmann first discovered dip angle in 1544, when he noticed the needle on a compass dipped towards the north hemisphere.

When the aircraft turns further towards South, the magnetic compass needle will tend to lead the actual heading of the aircraft.

She is taken to a circular operating table and tied down whilst a breathing apparatus is attached to her face, followed by a thin needle drill moving towards her.

In the furnace room, the needle on a pressure gauge vibrates towards the end of the scale and the rivets on the machinery give.

Most flute keys have needle springs, made of phosphor bronze, stainless steel, beryllium copper, or a gold alloy.

They indicate the exposure either with a needle galvanometer or on an LCD screen.

Some of these are blood, injuries, the sight of the needle physically or on a screen, paper pins, examination rooms, hospitals, white lab coats, hospital gowns, doctors, dentists, nurses, the antiseptic smell associated with offices and hospitals, the sight of a person who physically resembles the patient's regular health care provider, or even reading about the fear.

A circular knitting needle can also be used to create flat-knitted pieces that are too large for ordinary straight knitting needles, such as afghans and blankets.

At specific points indicated by the pattern, the cable needle is moved, the stitches on it are worked by the other needles, then the cable needle is turned around to a different position to create the cable twist.

Where the etching technique uses a needle to make lines that retain ink, aquatint relies on powdered rosin which is acid resistant in the ground to create a tonal effect.

* 1865 – Clay invents the double-headed latch needle which has enabled to create purl stitch knitting.

Where the engraving technique uses a needle to make lines that print in black ( or whatever colour ink is used ), aquatint uses powdered rosin to create a tonal effect.

BD used this invention to create a system that included the vacuum pressurized sleeve, and a cannula with sleeve attached to a holder that holds the needle / sleeve combination, and guides the negatively pressured collection vial that is inserted once the needle is in the patient.

To create free-motion machine embroidery, the embroiderer runs the machine and skillfully moves tightly hooped fabric under the needle to create a design.

Industrial and commercial embroidery machines and combination sewing-embroidery machines have a hooping or framing system that holds the framed area of fabric taut under the sewing needle and moves it automatically to create a design from a pre-programmed digital embroidery pattern.

The end is bevelled to create a sharp pointed tip letting the needle easily penetrate the skin.

Loopers serve to create thread loops that pass from the needle thread to the edges of the fabric so that the edges of the fabric are contained within the seam.

Unlike standard lockstitching, which uses a bobbin, overlock sewing machines utilize loopers to create thread loops for the needle to pass through, in a manner similar to crocheting.

Bunka artists use a specialized embroidery needle and rayon threads to create very detailed pictures that some liken to oil paintings.
