Vagina | of the skin is relatively resistant to water because it contains high levels of lipids. The vaginal epithelium contains lower levels of lipids. This allows the passage of water and water-soluble substances through the tissue. Keratinization happens when the epithelium is exposed to the dry external atmosphere. In abnormal circumstances, such as in pelvic organ prolapse, the mucosa may be exposed to air, becoming dry and keratinized. Blood is supplied to the vagina mainly via the vaginal artery, which | https://en.wikipedia.org/wiki?curid=32476 |
Capacitor | Capacitor Examples of dielectric media are glass, air, paper, plastic, ceramic, and even a semiconductor depletion region chemically identical to the conductors. From Coulomb's law a charge on one conductor will exert a force on the charge carriers within the other conductor, attracting opposite polarity charge and repelling like polarity charges, thus an opposite polarity charge will be induced on the surface of the other conductor. The conductors thus hold equal and opposite charges on their facing | https://en.wikipedia.org/wiki?curid=4932111 |

The reclaimed resources can be used for increased parallel computation, other functions, communication or memory, as well as increased input/output capabilities. This comes at the opportunity cost of less general-purpose utility.

Tree (data structure) | Tree (data structure) The structure is subject to the following conditions: The partial order structure ("X", ≤, ≤) is obtained as follows: Ordered trees can be naturally encoded by finite sequences of natural numbers. Denote ω the set of all finite sequences of natural numbers. Then any non-empty subset of ω that is closed under taking prefixes gives rise to an ordered tree: just take the prefix order for ≥ and the lexicographical order for Conversely, for an ordered tree "T" = ("X", ≤) assign each node | https://en.wikipedia.org/wiki?curid=30806 |

The ATSC transmission method is not robust enough against Doppler shift and multipath radio interference in mobile environments, and is designed for highly directional fixed antennas. To overcome these issues, additional channel coding mechanisms are introduced in to protect the signal.

Wildlife corridor | actually more successful than overpasses because many times animals are too timid to cross over a bridge in front of traffic and would prefer to be more hidden (Dole et al. 2003). Corridors can be expensive to plan out and put into action.

The spiritual teacher Meher Baba described the differences between lust and love: In lust there is reliance upon the object of sense and consequent spiritual subordination of the soul to it, but love puts the soul into direct and co-ordinate relation with the reality which is behind the form.

Differential trace pairs help to reduce these effects. A third difference between on-chip and chip-to-chip connection involves the cross-sectional size of the signal conductor, namely that PCB conductors are much larger (typically or more in width).

Entry point | with the arguments passed to the program. Example: Python programs are evaluated top-to-bottom, as is usual in scripting languages: the entry point is the start of the source code. Since definitions must precede use, programs are typically structured with definitions at the top and the code to execute at the bottom (unindented), similar to code for a one-pass compiler, such as in Pascal.

Image segmentation | thresholding, Otsu's method (maximum variance), and k-means clustering. Recently, methods have been developed for thresholding computed tomography (CT) images. The key idea is that, unlike Otsu's method, the thresholds are derived from the radiographs instead of the (reconstructed) image. New methods suggested the usage of multi-dimensional fuzzy rule-based non-linear thresholds. In these works decision over each pixel's membership to a segment is based on multi-dimensional rules derived from fuzzy logic | https://en.wikipedia.org/wiki?curid=505717 |

It is about half the length of a D-sub and its primary application is space-grade technology.

Allometry | Allometry This drag or resistance can be seen in two distinct flow patterns. There is Laminar Flow where the fluid is relatively uninterrupted after the organism moves through it. Turbulent flow is the opposite, where the fluid moves roughly around an organisms that creates vortices that absorb energy from the propulsion or momentum of the organism. Scaling also affects locomotion through a fluid because of the energy needed to propel an organism and to keep up velocity through momentum.

Integrating ADC | If the resolution requirement is reduced to 10 bits, the measurement time is also reduced to only 0.2 milliseconds (almost 4900 samples per second). There are limits to the maximum resolution of the dual-slope integrating ADC. It is not possible to increase the resolution of the basic dual-slope ADC to arbitrarily high values by using longer measurement times or faster clocks. Resolution is limited by: The basic design of the dual-slope integrating ADC has a limitations in both conversion speed and | https://en.wikipedia.org/wiki?curid=22269055 |
CMOS | (for e.g., p-type diffusion vs. n-well), wells and substrate (for e.g., n-well vs. p-substrate). In modern process diode leakage is very small compared to sub threshold and tunnelling currents, so these may be neglected during power calculations. If the ratios do not match, then there might be different currents of PMOS and NMOS; this may lead to imbalance and thus improper current causes the to heat up and dissipate power unnecessarily. circuits dissipate power by charging the various load capacitances | https://en.wikipedia.org/wiki?curid=49420 |
Last mile | Last mile Relative to the last-mile problem, these longer wavelengths have an advantage over light waves when omnidirectional or sectored transmissions are considered. The larger aperture of radio antennas results in much greater signal levels for a given path length and therefore higher information capacity. On the other hand, the lower carrier frequencies are not able to support the high information bandwidths, which are required by Shannon's equation when the practical limits of S/N have been reached. | https://en.wikipedia.org/wiki?curid=285718 |
Cooling tower | Cooling tower The cool water absorbs heat from the hot process streams which need to be cooled or condensed, and the absorbed heat warms the circulating water (C). The warm water returns to the top of the cooling tower and trickles downward over the fill material inside the tower. As it trickles down, it contacts ambient air rising up through the tower either by natural draft or by forced draft using large fans in the tower. That contact causes a small amount of the water to be lost as windage or drift (W) | https://en.wikipedia.org/wiki?curid=750772 |

Hot-carrier injection | usually is made of silicon dioxide (SiO). To become “hot” and enter the conduction band of SiO, an electron must gain a kinetic energy of ~3.2 eV. For holes, the valence band offset in this case dictates they must have a kinetic energy of 4.6 eV. The term "hot electron" comes from the effective temperature term used when modelling carrier density (i.e., with a Fermi-Dirac function) and does not refer to the bulk temperature of the semiconductor (which can be physically cold, although the warmer it is, the | https://en.wikipedia.org/wiki?curid=7084895 |

Switched Mode Power Supply is basically DC-DC converters. If the input is AC, the input is first rectified to get the DC.

Lakoff and Johnson contend this is similar with other spatial orientations such as front and back too.

Genetic code | single direction reading and translating single codons into single amino acids. The genetic code is a key part of the history of life, according to one version of which self-replicating RNA molecules preceded life as we know it. This is the RNA world hypothesis.

Introduction to genetics | Some traits are part of an organisms' physical appearance; such as a person's eye color, height or weight. Other sorts of traits are not easily seen and include blood types or resistance to diseases. Some traits are inherited through our genes, so tall and thin people tend to have tall and thin children. Other traits come from interactions between our genes and the environment, so a child might inherit the tendency to be tall, but if they are poorly nourished, they will still be short.
