A die in the context of integrated circuits is a small block of semiconducting material, on which a given functional circuit is fabricated. Typically, integrated circuits are produced in large batches on a single wafer of electronic-grade silicon (EGS) or other semiconductor (such as GaAs) through processes such as photolithography. The wafer is cut (“diced”) into many pieces, each containing one copy of the circuit. Each of these pieces is called a die.
There are three commonly used plural forms: dice, dies, and die.
Single NPN bipolar junction transistor die.

A die is a specialized tool used in manufacturing industries to cut or shape material mostly using a press. Like molds, dies are generally customized to the item they are used to create. Products made with dies range from simple paper clips to complex pieces used in advanced technology.
Forming dies are typically made by tool and die makers and put into production after mounting into a press. The die is a metal block that is used for forming materials like sheet metal and plastic. For the vacuum forming of plastic sheet only a single form is used, typically to form transparent plastic containers (called blister packs) for merchandise. Vacuum forming is considered a simple molding thermoforming process but uses the same principles as die forming. For the forming of sheet metal, such as automobile body parts, two parts may be used: one, called the punch, performs the stretching, bending, and/or blanking operation, while another part, called the die block, securely clamps the workpiece and provides similar stretching, bending, and/or blanking operation. The workpiece may pass through several stages using different tools or operations to obtain the final form. In the case of an automotive component there will usually be a shearing operation after the main forming is done and then additional crimping or rolling operations to ensure that all sharp edges are hidden and to add rigidity to the panel.
The acids in wine are an important component in both winemaking and the finished product of wine. They are present in both grapes and wine, having direct influences on the color, balance and taste of the wine as well as the growth and vitality of yeast during fermentation and protecting the wine from bacteria. The measure of the amount of acidity in wine is known as the “titratable acidity” or “total acidity”, which refers to the test that yields the total of all acids present, while strength of acidity is measured according to pH, with most wines having a pH between 2.9 and 3.9. Generally, the lower the pH, the higher the acidity in the wine. However, there is no direct connection between total acidity and pH (it is possible to find wines with a high pH for wine and high acidity). In wine tasting, the term “acidity” refers to the fresh, tart and sour attributes of the wine which are evaluated in relation to how well the acidity balances out the sweetness and bitter components of the wine such as tannins. Three primary acids are found in wine grapes: tartaric, malic and citric acids. During the course of winemaking and in the finished wines, acetic, butyric, lactic and succinic acids can play significant roles. Most of the acids involved with wine are fixed acids with the notable exception of acetic acid, mostly found in vinegar, which is volatile and can contribute to the wine fault known as volatile acidity. Sometimes, additional acids, such as ascorbic, sorbic and sulfurous acids, are used in winemaking.
An acid is any chemical compound that, when dissolved in water, gives a solution with a pH less than 7.0.
Acid or ACID may also refer to:
Lysergic acid diethylamide (/daɪ eθəl ˈæmaɪd/ or /æmɪd/ or /eɪmaɪd/), abbreviated LSD or LSD-25, also known as lysergide (INN) and colloquially as acid, is a psychedelic drug of the ergoline family, well known for its psychological effects—which can include altered thinking processes, closed- and open-eye visuals, synesthesia, an altered sense of time, and spiritual experiences—as well as for its key role in 1960s counterculture. It is used mainly as an entheogen and recreational drug. LSD is not addictive. However, acute adverse psychiatric reactions such as anxiety, paranoia, and delusions are possible.
LSD was first synthesized by Albert Hofmann in 1938 from ergotamine, a chemical derived by Arthur Stoll from ergot, a grain fungus that typically grows on rye. The short form "LSD" comes from its early code name LSD-25, which is an abbreviation for the German "Lysergsäure-diethylamid" followed by a sequential number. LSD is sensitive to oxygen, ultraviolet light, and chlorine, especially in solution, though its potency may last for years if it is stored away from light and moisture at low temperature. In pure form it is a colorless, odorless, tasteless solid. LSD is typically either swallowed (oral) or held under the tongue (sublingual), usually on a substrate such as absorbent blotter paper, a sugar cube, or gelatin. In its liquid form, it can also be administered by intramuscular or intravenous injection. Interestingly, unlike most other classes of illicit drugs and other groups of psychedelic drugs such as tryptamines and phenethylamines, when LSD is administered via intravenous injection the onset is not immediate, instead taking approximately 30 minutes before the effects are realized. LSD is very potent, with 20–30 µg (micrograms) being the threshold dose.
regnen tut's, die Fuesse tun mir schon weh.
Der Pfarrer sagt, sie war ein so herzensguter Mensch,
und trotzdem faellt mir's Weinen heut' so schwer.
Die Omama, die Oma ist nicht mehr.
Wie ich klein war, hat's mir einegstopft die Knoedln,
hat's glauert mit dem Pracker in der Hand;
hat's mir auch umdraht schon den Magen,
es war ihr wurscht, sie hat mi gschlagen,
so lang, dass i schon angfangt hab zum Beten:
Lieb Jesukind, lass d'Oma doch verrecken.
Die sieben Raben, es wars nur sechs,
die gute Fee, es war a Hex,
der boese Wolf, ein kleiner Dackel,
der Maerchenprinz, ein schiacher Lackel.
In Stammersdorf hat s' ghabt die kleine Wohnung
mit Spitzendeckerln und ein Hitlerbild,
a Glasl Grammelschmalz am Fensterbrett,
den Nachtscherbn unterm Doppelbett,
so weiss, so dick, so rund und immer voll.
Vielleicht haett ma'n in's Grab dazulegn solln ?
Einmal hab ich s' gfragt: "Wo ist der Opa?"
"Im Himmel auf an Wolkerl spielt er Geign."
Fuer Fuehrer, Volk und Vaterland
erschossen, aughaengt und verbrannt,
auch das hat sie dem Adolf stets verziehn.
Er hat ihr ja das Mutterkreuz verliehn.
Die sieben Raben ...
In letzter Zeit da war's schon bisserl komisch.
Das Grammelschmalz is gstanden unterm Bett,
die Spitzendeckerl hat s' verbrannt,
den Hitler hat s' an Puelcher gnannt,
den Nachtscherbn hat s' plaziert am Fensterbrett.
Ganz Stammersdorf hat ueber sie schon gredt.
Am Muttertag da habn wir s' gfuehrt in Prater,
die Alte war auf einmal wieder jung.
Beim Go-Cart-Fahrn hat s' gjodelt,
ein paar Langos hat s' verdruckt,
nur beim Sturmboot fahrn, da geschah ein Missgeschick:
Da is s' an ihre falschen Zaehn derstickt.
Die sieben Raben ...
Oma, pfueadigott, mach's drueben besser,
mach keine Knoedeln fuer die Engerln, sei so gut!
Tu nicht die Heiligen sekkiern, tu nicht den Opa denunziern;
und gehst zum Herrgott auf Besuch - ein guter Tip:
