Examples of Lombard band in the following topics:
-
- The style can be attributed to great architectural activity by groups of Lombard teachers and stonemasons working in the Catalan territory during the first quarter of the 11th century.
- The First Romanesque style, also known as Lombard Romanesque style, is characterized by thick walls, lack of sculpture, and the presence of rhythmic ornamental arches known as a Lombard band.
- For example, Abott Oliba ordered an extension to the Monastery of Santa Maria de Ripoll in 1032 mirroring the First Romanesque characteristics of two frontal towers, a cruise with seven apses, and Lombard ornamentation of blind arches and vertical strips.

- According to band theory, a conductor is simply a material that has its valence band and conduction band overlapping, allowing electrons to flow through the material with minimal applied voltage.
- In solid-state physics, the band structure of a solid describes those ranges of energy, called energy bands, that an electron within the solid may have ("allowed bands") and ranges of energy called band gaps ("forbidden bands"), which it may not have.
- Band theory models the behavior of electrons in solids by postulating the existence of energy bands.
- On the left, a conductor (described as a metal here) has its empty bands and filled bands overlapping, allowing excited electrons to flow through the empty band with little push (voltage).
- Apply the concept of band theory to explain the behavior of conductors.

- The first of these conquering campaigns was against the Lombards; Charlemagne came out victorious and won the Lombard lands to the north of Italy.
- Charlemagne and his uncle Bernard crossed the Alps in 773 and chased the Lombards back to Pavia, which they then besieged.
- After the pope granted Charlemagne the title of patrician, he returned to Pavia, where the Lombards were on the verge of surrendering.
- In return for their lives, the Lombards conceded and opened the gates in early summer.
-
- The I-band is spanned by the titin
molecule connecting the Z-line with a myosin filament.
- The region between two
neighboring, parallel I-bands is known as the A-band and contains the entire
length of single myosin myofilaments.
- Within the A-band is a region known as
the H-band, which is the region not superimposed by actin myofilaments.
- The myofilaments themselves do not contract or expand and so the A-band remains
constant.
- During stretching this tension is release and the I and H bands expand.
-
- Most of the states with low energy (closer to the nucleus) are occupied, up to a particular band called the valence band.
- In semiconductors, only a few electrons exist in the conduction band just above the valence band, and an insulator has almost no free electrons.
- Semiconductors and insulators are further distinguished by the relative band gap.
- In semiconductors, the band gap is small, allowing electrons to populate the conduction band.
- As the energy in the system increases, electrons leave the valence band and enter the conduction band.
-
- In the atomic lattice of a substance, there is a set of filled atomic energy "bands" with a full complement of electrons, and a set of higher energy unfilled "bands" which have no electrons.
- The highest energy band contains valence electrons available for chemical reactions.
- The conduction band is the band above the valence band.
- Electrons in the conduction band are free to move about in the lattice and can conduct current.
- In order for a substance to conduct electricity, its valence electrons must cross the band gap, which is the energy gap between the valence band and conduction band.
-
- At the point, the molecules stopped sedimenting and formed a stable band.
- The molecules that form the lowest bands have the highest densities.
- The DNA harvested from cells grown for two generations in 14N formed two bands: one DNA band was at the intermediate position between 15N and 14N and the other corresponded to the band of exclusively 14N DNA.
- Dispersive replication would have resulted in exclusively a single band in each new generation, with the band slowly moving up closer to the height of the 14N DNA band.
- DNA grown in 15N (red band) is heavier than DNA grown in 14N (orange band) and sediments to a lower level in the cesium chloride density gradient in an ultracentrifuge.
-
- A central bank does not specify an exact price, but it allows its currency to fluctuate within a band, depicted in Figure 8.
- Consequently, a central bank allows the market to change the exchange rate within the band.
- If the exchange rate falls outside of the band, then the central bank must intervene in the currency market to return the exchange rate back within the band.
- Thus, the exchange rate returns within the band.
- If a central bank allows its currency to appreciate permanently outside the band, then we call it a revaluation.
-
- Crawling bands: The market value of a national currency is permitted to fluctuate within a range specified by a band of fluctuation.
- This band is determined by international agreements or by unilateral decision by a central bank.
- The bands are adjusted periodically by the country's central bank.
- Generally the bands are adjusted in response to economic circumstances and indicators.
- Pegged with horizontal bands:This system is similar to crawling bands, but the currency is allowed to fluctuate within a larger band of greater than one percent of the currency's value.

- To investigate force standards and cause and effect, get two identical rubber bands.
- Hang one rubber band vertically on a hook.
- Find a small household item that could be attached to the rubber band using a paper clip, and use this item as a weight to investigate the stretch of the rubber band.
- Measure the amount of stretch produced in the rubber band with one, two, and four of these (identical) items suspended from the rubber band.
- How large a stretch would you expect for the same number of items suspended from two rubber bands?
