Opus emplectum is an advanced Roman construction technique. Each side of a wall is constructed with finished stone blocks, leaving a substantial void between them. The void is filled with a mixture of broken stones mixed with mortar. [1] A good example of this technique are the ruins of the Romanesque tower in Strzelno.
Density is a substance's mass per unit of volume. The symbol most often used for density is ρ, although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume:
Masonry is the craft of building a structure with brick, stone, or similar material, including mortar plastering which are often laid in, bound and pasted together by mortar. The term masonry can also refer to the building units themselves.
In computer science, a recursive descent parser is a kind of top-down parser built from a set of mutually recursive procedures where each such procedure implements one of the nonterminals of the grammar. Thus the structure of the resulting program closely mirrors that of the grammar it recognizes.
Urination is the release of urine from the bladder through the urethra to the outside of the body. It is the urinary system's form of excretion. It is also known medically as micturition, voiding, uresis, or, rarely, emiction, and known colloquially by various names including peeing, weeing, pissing, and euphemistically going number one. In healthy humans and other animals, the process of urination is under voluntary control. In infants, some elderly individuals, and those with neurological injury, urination may occur as a reflex. It is normal for adult humans to urinate up to seven times during the day.
The Book of Five Rings is a text on kenjutsu and the martial arts in general, written by the Japanese swordsman Miyamoto Musashi around 1645. Many translations have been made, and it garnered broad attention in East Asia and worldwide. For instance, some foreign business leaders find its discussion of conflict to be relevant to their work. The modern-day Hyōhō Niten Ichi-ryū employs it as a manual of technique and philosophy.
Stonemasonry or stonecraft is the creation of buildings, structures, and sculpture using stone as the primary material. Stonemasonry is the craft of shaping and arranging stones, often together with mortar and even the ancient lime mortar, to wall or cover formed structures.
Nicolas-Joseph Cugnot was a French inventor who built the world's first full-size and working self-propelled mechanical land-vehicle, the "Fardier à vapeur" – effectively the world's first automobile.
Dry stone, sometimes called drystack or, in Scotland, drystane, is a building method by which structures are constructed from stones without any mortar to bind them together. A certain amount of binding is obtained through the use of carefully selected interlocking stones.
In trick-taking games, to ruff means to play a trump card to a trick. According to the rules of most games, a player must have no cards left in the suit led in order to ruff. Since the other players are constrained to follow suit if they can, even a low trump can win a trick. In some games, like Pinochle and Preferans, the player who cannot follow suit is required to ruff. In others, like Bridge and Whist, he may instead discard. Normally, ruffing will win a trick. But it is also possible that a subsequent player will overruff. Historically, ruff meant to "rob" i.e. exchange a card with the stock.
Urinary retention is an inability to completely empty the bladder. Onset can be sudden or gradual. When of sudden onset, symptoms include an inability to urinate and lower abdominal pain. When of gradual onset, symptoms may include loss of bladder control, mild lower abdominal pain, and a weak urine stream. Those with long-term problems are at risk of urinary tract infections.
Dangling pointers and wild pointers in computer programming are pointers that do not point to a valid object of the appropriate type. These are special cases of memory safety violations. More generally, dangling references and wild references are references that do not resolve to a valid destination.
Ferrocement or ferro-cement is a system of construction using reinforced mortar or plaster applied over an "armature" of metal mesh, woven, expanded metal, or metal-fibers, and closely spaced thin steel rods such as rebar. The metal commonly used is iron or some type of steel, and the mesh is made with wire with a diameter between 0.5 mm and 1 mm. The cement is typically a very rich mix of sand and cement in a 3:1 ratio; when used for making boards, no gravel is used, so that the material is not concrete.
Where I'm Coming From is the 13th studio album by Stevie Wonder.

All nine songs were written by Wonder and Motown singer-songwriter Syreeta Wright, his first wife. It was the last album produced under his first contract with Motown Records.

Salvator Fabris (1544-1618) was an Italian fencing master from Padua. During his life he taught in various European countries, most notably in Denmark where he was the fencing instructor of King Christian IV. It was during his time in Copenhagen that he published his treatise on rapier fencing, Lo Schermo, overo Scienza d’Arme, in 1606. The treatise became a fencing bestseller around Europe, and was reprinted until 1713 and translated into several languages, notably into German, and again in 2005, into English.
Trump promotion is a technique in contract bridge where the defenders create an otherwise non-existing trump trick for themselves. The most common type of trump promotion occurs when one defender plays a side suit through, in which both the declarer's hand and the other defender are void:
A corbel arch is an arch-like construction method that uses the architectural technique of corbeling to span a space or void in a structure, such as an entranceway in a wall or as the span of a bridge. A corbel vault uses this technique to support the superstructure of a building's roof.
James Joseph Woolley was an American keyboard and synthesizer player, best known for performing with industrial rock band Nine Inch Nails during the 1991 Lollapalooza Tour, Downward Spiral and the beginning part of the 1994 Self Destruct Tour. Woolley also appeared in the videos for "Wish" and "March of the Pigs", as well as parts of the Nine Inch Nails release Closure (1997). Woolley won a Grammy Award in 1995 for "Best Metal Performance" for the Woodstock performance of "Happiness in Slavery".
In urology, voiding cystourethrography (VCUG) is a frequently performed technique for visualizing a person's urethra and urinary bladder while the person urinates (voids). It is used in the diagnosis of vesicoureteral reflux, among other disorders. The technique consists of catheterizing the person in order to fill the bladder with a radiocontrast agent, typically diatrizoic acid. Under fluoroscopy the radiologist watches the contrast enter the bladder and looks at the anatomy of the patient. If the contrast moves into the ureters and back into the kidneys, the radiologist makes the diagnosis of vesicoureteral reflux, and gives the degree of severity a score. The exam ends when the person voids while the radiologist is watching under fluoroscopy. Consumption of fluid promotes excretion of contrast media after the procedure. It is important to watch the contrast during voiding, because this is when the bladder has the most pressure, and it is most likely this is when reflux will occur. Despite this detailed description of the procedure, at least as of 2016 the technique had not been standardized across practices.
