Nevertheless, the usage of Treptichnus pedum, a reference ichnofossil for the lower boundary of the Cambrian, for the stratigraphic detection of this boundary is always risky because of occurrence of very similar trace fossils belonging to the Treptichnids group well below the T. pedum in Namibia, Spain and Newfoundland, and possibly, in the western USA.

The Vendian concept was formed stratigraphically top-down, and the lower boundary of the Cambrian became the upper boundary of the Vendian.

The lower boundary of the Vendian was suggested to be defined at the base of the Varanger ( Laplandian ) tillites.

The lower boundary GSSP of the Ediacaran is at the base of the cap carbonate ( Nuccaleena Formation ), immediately above the Elatina diamictite in the Enorama Creek section, Brachina Gorge, Flinders Ranges, South Australia.

The GSSP of the upper boundary of the Ediacaran is the lower boundary of the Cambrian on the SE coast of Newfoundland approved by the International Commission on Stratigraphy as a preferred alternative to the base of the Tommotian Stage in Siberia which was selected on the basis of the ichnofossils Treptichnus pedum.

As to the Treptichnus pedum, a reference ichnofossil for the lower boundary of the Cambrian, its usage for the stratigraphic detection of this boundary is always risky because of the occurrence of very similar trace fossils belonging to the Treptichnids group well below the T. pedum in Namibia, Spain and Newfoundland, and possibly, in the western United States.

Hernando de Alarcón, a Spanish navigator of the 16th century, noted for having led an early expedition to the Baja California peninsula, meant to be coordinated with Francisco Vasquéz de Coronado's overland expedition, and for penetrating the lower Colorado River, perhaps as far as the modern California-Arizona boundary.

The lower ( Triassic ) boundary is set by the Permian-Triassic extinction event, during which approximately 90 % to 96 % of marine species and 70 % of terrestrial vertebrates became extinct.

His argument relies on the assumption that boundary conditions supply degrees of freedom that instead of being random are determined by higher level realities whose properties are dependent, but distinct, from the lower level from which they emerge.

Mesoscale meteorology is the study of atmospheric phenomena that has horizontal scales ranging from microscale limits to synoptic scale limits and a vertical scale that starts at the Earth's surface and includes the atmospheric boundary layer, troposphere, tropopause, and the lower section of the stratosphere.

In all cases, microwave includes the entire SHF band ( 3 to 30 GHz, or 10 to 1 cm ) at minimum, with RF engineering often putting the lower boundary at 1 GHz ( 30 cm ), and the upper around 100 GHz ( 3 mm ).

* Proterozoic: this eon refers to the time from the lower Cambrian boundary, 542 Ma, back through 2500 Ma.

** Neoproterozoic: The youngest geologic era of the Proterozoic Eon, from the Cambrian Period lower boundary ( 542 Ma ) back to 1000 Ma.

Other tributaries of the Warta within Poznań are the Junikowo Stream ( Strumień Junikowski ), which flows through southern Poznań from the west, meeting the Warta just outside the city boundary in Luboń ; the Bogdanka and Wierzbak, formerly two separate tributaries flowing from the north-west and along the north side of the city centre, now with their lower sections diverted underground ; the Główna, flowing through the neighbourhood of the same name in north-east Poznań ; and the Rose Stream ( Strumień Różany ) flowing east from Morasko in the north of the city.

In all cases, microwave includes the entire SHF band ( 3 to 30 GHz, or 10 to 1 cm ) at minimum, with RF engineering often putting the lower boundary at 1 GHz ( 30 cm ), and the upper around 100 GHz ( 3mm ).

In its lower course, it forms part of the boundary between the two states and empties into Sabine Lake, an estuary of the Gulf of Mexico.

It is very likely that further investigations will push back the Sri Lankan lower boundary to match that of South India.

If the refractive index is lower on the other side of the boundary and the incident angle is greater than the critical angle, no light can pass through and all of the light is reflected.

Signals in a higher refractive index layer, i. e., duct, tend to remain in that layer because of the reflection and refraction encountered at the boundary with a lower refractive index material.

A drop may form when liquid accumulates at the lower end of a tube or other surface boundary, producing a hanging drop called a pendant drop.

The Vendian in its type area consists of large subdivisions such as Laplandian, Redkino, Kotlin and Rovno Regional stages with the globally traceable subdivisions and their boundaries, including its lower one.

They cite the Cambrian explosion — the appearance of abundant fossils in the upper Ediacaran ( Vendian ) Period and lower Cambrian Period — as the pre-Flood / Flood boundary, the presence in such sediments of fossils that do not occur later in the geological record as part of a pre – flood biota that perished and the absence of fossilized organisms that appear later, such as angiosperms and mammals, as due to erosion of sediments deposited by the flood as waters receded off the land.

To Serenissimus such tribes as the Cossacks of the Don or those ex-bandits the Zaporogian Cossacks ( in whose islands along the lower Dnieper the Polish novelist Sienkiewicz would one day place With Fire And Sword ) were just elements for enforced resettlement in, say, Bessarabia, where, as `` the faithful of the Black Sea borders '', he could use their presence as bargaining points in the Czarina's territorial claims against Turkey.

To document his charge, Pike set up two parallel columns in The Advocate showing the price charged by The Gazette and the considerably lower price for which the work could be done elsewhere.

If Woodruff could not furnish a strong explanation, the governor insisted that he lower his prices in accord with the scale printed in The Advocate.

The principal potential advantage would be that the finished product could be transported and stored at lower cost under refrigeration instead of being frozen.

With the lower dealer inventories and the stepped-up demand some manufacturers believe there could be shortages of some implements.

Clearly there is always at least one such string for any n, as otherwise all possible strings ( infinitely many ) could be generated by the ( finitely many ) programs with lower complexity, so GenerateComplexString must always return.

The Saxons are placed around the lower Elbe, which area they could have reached merely by an extension of the Saxon alliance.

The display logic and resulting display ' snow ' was irritating, as was the missing lower case support, the CPU speed could be improved, the quality and layout of the keyboard was bothersome, and the floppy disk capacity and reliability was low.

A key point which is often overlooked is that published lower bounds for problems are often given for a model of computation that is more restricted than the set of operations that you could use in practice and therefore there are algorithms that are faster than what would naively be thought possible.

The weight saved from the lack of a turret could allow more armour to be fitted, and the lower profile allowed this armour to be concentrated in the hull.

Apollinarism or Apollinarianism was a view proposed by Apollinaris of Laodicea ( died 390 ) that Jesus could not have had a human mind ; rather, that Jesus had a human body and lower soul ( the seat of the emotions ) but a divine mind.

LOB % tends to regress toward 70 – 72 % over time, so unusually high or low percentages could indicate that pitcher's ERA could be expected to rise or lower in the future.

Another risk of the hit-and-run is that a caught line drive could result in an easy double play, although this is offset by the lower likelihood of a ground ball double play.

The company simply could not keep paying out and the adjusters could not help lower the payments due to the high building code the Islands adhere to.

Diamond's very high scratch resistance and thermal conductivity, combined with a lower coefficient of thermal expansion than Pyrex glass, a coefficient of friction close to that of Teflon ( Polytetrafluoroethylene ) and strong lipophilicity would make it a nearly ideal non-stick coating for cookware if large substrate areas could be coated economically.

This is closely related to the increase in the size of armies throughout the early modern period ; heavily armored cavalrymen were expensive to raise and maintain and it took years to replace a skilled horseman or a trained horse, while arquebusiers and later musketeers could be trained and kept in the field at much lower cost, and were much easier to replace.

It was noted that survival rates in Chagas patients could be significantly improved by using lower dosages of the immunosuppressant drug ciclosporin.

With the addition of a pedal clavichord, which included a pedal keyboard for the lower notes, a clavichord could be used to practice organist repertoire.

While Canion developed an 18-month plan to create a line of low-priced computers, Rosen sent his own Compaq engineering team to Comdex without Canion's knowledge and discovered that a low-priced PC could be made in half the time and at lower cost than Canion's initiative.

However, a wall would imply the existence of a defensive ditch outside it, so an earlier wall could not be immediately adjacent to site of the tomb, which combined with the presence of the Temple Mount would make the city inside the wall quite thin ; essentially for the traditional site to have been outside the wall, the city would have had to be limited to the lower parts of the Tyropoeon Valley, rather than including the defensively advantageous western hill.

However, by this time other machines in DEC's lineup could fill the same niche at even lower price points, and the PDP-15 would be the last of the 18-bit series.

The design has the same precision on all columns, but when calculating polynomials, the precision on the higher-order columns could be lower.

This practice could be sustained only by requisitioning precious metals from private citizens in exchange for state-minted coin ( of a far lower value than the price of the precious metals requisitioned ).
