Male accessory gland infection (MAGI) is a condition with signs of inflammation involving one or more sites in the male genital tract. Diagnosis is made according to parameters defined by the World Health Organization , and it is particularly made in relation to infectious or inflammatory causes of male infertility .
The male accessory glands are the ampullary gland, seminal vesicle, prostate, bulbourethral gland, and urethral gland. [5]The products of these glands serve to nourish and activate the spermatozoa, to clear the urethral tract prior to ejaculation, serve as the vehicle of transport of the spermatozoa in the female tract, and to plug the female tract after placement of spermatozoa to help ensure ...
A metal rectifier is an early type of semiconductor rectifier in which the semiconductor is copper oxide, germanium or selenium. They were used in power applications to convert alternating current to direct current in devices such as radios and battery chargers .
A grey, grey-blue or grey-brown color indicates a good seal. A metallic color indicates lack of oxide, while black color indicates overly oxidized metal, in both cases leading to a weak joint.[2] [citation needed] The name Kovar is often used as a general term for Fe–Ni alloys with these particular thermal expansion properties.
The unit cell of high-temperature cuprate superconductor BSCCO-2212. Cuprates are layered materials, consisting of superconducting planes of copper oxide, separated by layers containing ions such as lanthanum, barium, strontium, which act as a charge reservoir, doping electrons or holes into the copper-oxide planes.
As a significant product of copper mining, copper(II) oxide is the starting point for the production of many other copper salts. For example, many wood preservatives are produced from copper oxide. [3] Cupric oxide is used as a pigment in ceramics to produce blue, red, and green, and sometimes gray, pink, or black glazes. [3]
Ducts for air pollution control in a 17000 standard cubic feet per minute regenerative thermal oxidizer (RTO). A round galvanized steel duct connecting to a typical diffuser Fire-resistance rated mechanical shaft with HVAC sheet metal ducting and copper piping, as well as "HOW" (Head-Of-Wall) joint between top of concrete block wall and underside of concrete slab, firestopped with ceramic ...
Delafossite is a copper iron oxide mineral with formula CuFeO 2 or Cu 1+ Fe 3+ O 2.It is a member of the delafossite mineral group, which has the general formula ABO 2, a group characterized by sheets of linearly coordinated A cations stacked between edge-shared octahedral layers (BO 6). [5]
