Nitrocyclohexane. Nitrocyclohexane is an organic compound with the molecular formula C6H11NO2. It is a colorless liquid, but degraded samples appear pale yellow.  It once was produced commercially as a precursor to caprolactam].

Preparation
It is prepared by reaction of nitrogen dioxide with cyclohexane, the so-called Nixian process.  Cyclohexane is a convenient substrate because all twelve C-H bonds are equivalent, so mononitration does not give isomers (unlike the case of n-hexane).

Hazards
Nitrocyclohexane is highly flammable and a strong oxidizing agent. It is listed as an extremely hazardous substance by the Emergency Planning and Community Right-to-Know Act, and the NOAA warns that it can be explosive.

Moisture cure polyurethane. Moisture-cure polyurethanes -- or polyurethane prepolymer -- are isocyanate-terminated prepolymers that are formulated to cure with ambient water.  Cured PURs are segmented copolymer polyurethane-ureas exhibiting microphase-separated morphologies.  One phase is derived from a typically flexible (subambient glass transition temperature, Tg) polyol that is generally referred to as the “soft phase”.  Likewise the corresponding “hard phase” is born from the di- or polyisocyanates that through water reaction produce a highly crosslinked material with softening temperature well above room temperature.

Application
Moisture cure polyurethanes have been widely used in the adhesive and coating industries. Thermal, mechanical, and surface properties of hyperbranched polyurethane-urea (HBPU) moisture cured coatings have been studied in relationship to chemical structure. Different NCO terminated HBPU prepolymers were prepared by reacting hyperbranched polymers with isophorone diisocyanate (IPDI) or 4,4'-bis-methylene cyclohexane diisocyanate (HMDI). A range of  NCO/OH eq. ratios from 1.2 - 1.6 was used. 

Thermal and mechanical properties of moisture cured polyurethane-urea /clay nanocomposite coatings have been studied in relationship to clay dispersion and intercalation of clay platelets in the urethane-urea matrix. Coatings were prepared by moisture curing of IPDI capped hydroxyl terminated polybutadiene/clay dispersions in a relative humidity (RH) of 50% at 25 °C. Moisture cured polyurethane–urea coatings have been made by reacting 1,2,3-triazole rich polyether polyols with HMDI at NCO/OH eq. ratio of 1.2 to obtain isocyanate-terminated polyurethane prepolymers. The prepolymers were cured under atmospheric moisture to make polyurethane–urea free films.

Neubrügg. The Neubrügg or Neubrücke () is a covered wooden bridge over the river Aare between the village of Kirchlindach and Bern in the canton of Bern in Switzerland. It is a Swiss heritage site of national significance.

History
The bridge was first built in 1469 to replace a ferry crossing over the Aare. The bridge eventually became part of two major roads that helped Bern control its extensive territory north of the river. The road into the Berner Seeland passed over the bridge before traveling to Meikirch, while the other road ran into the Fraubrunnenamt after passing through Oberlindach and Münchenbuchsee. The Neubrügg remained important until motorized traffic made it obsolete. It was supplanted by the concrete Halenbrücke in 1911-13.

Kinetic inhibitor. Kinetic inhibitors are a new and evolving technology of a class of Low Dosage Hydrate Inhibitors (LDHI) that are polymers and copolymers (or a mix thereof). The most common of which is polyvinylcaprolactam (PVCap). These inhibitors are primarily utilized to retard the formation of clathrate hydrates. This problem becomes most prominent in flow lines when hydrocarbons and water flow through a line. The pressure and cold temperatures that could be exposed to the flow lines provides an environment in which clathrate hydrates can form and plug up the flow line. The inhibitors generally slow the formation of the hydrates enough so the fluid reaches storage without causing blockage.

Structure
There may be variations on the types and structure of the polymer used as the inhibitor. However, in general, while the gas hydrate is forming, the cavity where the hydrocarbon usually resides. Instead, the alkyl group penetrates the cavity followed by the carbonyl group of the amide group hydrogen bonding to the surface of the hydrate, thus preventing the formation of hydrates.

Uses
These inhibitors chemically retard the formation of clathrate hydrates. Dosage of such inhibitors in the fluid is usually .3% to .5% by weight of the fluid, compared to 10% to 50% by weight for thermodynamic inhibitors for prevention of clathrate formation. Due to this and other factors, kinetic inhibitors are more cost effective than thermodynamic inhibitors. However, if the fluid is in a static environment (i.e. packer fluid), kinetic inhibitors will have limited effect as hydrates will still form over sufficient time. At this point the only viable option is thermodynamic inhibitors.

Electrical isolation test. In electrical engineering, an electrical isolation test is a direct current (DC) or alternating current (AC) resistance test that is performed on sub-systems of an electronic system to verify that a specified level of isolation resistance is met. Isolation testing may also be conducted between one or more electrical circuits of the same subsystem. The test often reveals problems that occurred during assembly, such as defective components, improper component placement, and insulator defects that may cause inadvertent shorting or grounding to chassis, in turn, compromising electrical circuit quality and product safety. 

Isolation resistance measurements may be achieved using a high input impedance ohmmeter, digital multimeter (DMM) or current-limited Hipot test instrument. The selected equipment should not over-stress sensitive electronic components comprising the subsystem. The test limits should also consider semiconductor components within the subsystem that may be activated by the potentials imposed by each type of test instrumentation. A minimum acceptable resistance value is usually specified (typically in the mega ohm (MΩ) range per circuit tested).  Multiple circuits having a common return may be tested simultaneously, provided the minimum allowable resistance value is based on the number of circuits in parallel.

Five basic isolation test configurations exist:
 Single Un-referenced End-Circuit – isolation between one input signal and circuit chassis/common ground.
 Multiple Un-referenced End-Circuits with a single return – isolation between several input signals and circuit chassis/common ground.
 Subsystem with Isolated Common – isolation between signal input and common ground.
 Common Chassis Ground – isolation between circuit common and chassis (chassis grounded).
 Isolated Circuit Common – isolation between circuit common and chassis (chassis floating).

Isolation measurements are made with the assembly or subsystem unpowered and disconnected from any support equipment.

Circle diagram. The circle diagram (also known as Heyland diagram or Heyland circle) is the graphical representation of the performance of the electrical machine drawn in terms of the locus of the machine's input voltage and current. It was first conceived by  in 1894 and Bernhard Arthur Behrend in 1895. A newer variant devised by  in 1899 is often named Ossanna diagram, Ossanna circle, Heyland-Ossanna diagram or Heyland-Ossanna circle.
In 1910,  further improved the diagram by also incorporating the rotor resistance, then called Sumec diagram or Sumec circle.

The circle diagram can be drawn for alternators, synchronous motors, transformers, induction motors. The Heyland diagram is an approximate representation of a circle diagram applied to induction motors, which assumes that stator input voltage, rotor resistance and rotor reactance are constant and stator resistance and core loss are zero. Another common circle diagram form is as described in the two constant air-gap induction motor images shown here,
where,
 Rs, Xs: Stator resistance and leakage reactance
 Rr', Xr', s: Rotor resistance and leakage reactance referred to the stator and rotor slip
 Rc, Xm, : Core and mechanical losses, magnetization reactance
 Vs, Impressed stator voltage
 I0 = OO', IBL = OA, I1 =OV: No load current, blocked rotor current, operating current
 Φ0, ΦBL : No load angle, blocked rotor angle
 Pmax,  sPmax, PFmax, Tmax, sTmax: Maximum output power & related slip, maximum power factor, maximum torque & related slip
 η1, s1, PF1, Φ1,: Efficiency,  slip, power factor, PF angle at operating current
 AB: Represents rotor power input, which divided by synchronous speed equals starting torque.

The circle diagram is drawn using the data obtained from no load and either short-circuit or, in case of machines, blocked rotor tests by fitting a half-circle in points O' and A.

Beyond the error inherent in the constant air-gap assumption, the circle diagram introduces errors due to rotor reactance and rotor resistance variations caused by magnetic saturation and rotor frequency over the range from no-load to operating speed.
