Human immunodeficiency virus type 1 (HIV-1) sequences that pre-date the recognition of AIDS are critical to defining the time of origin and the timescale of virus.

E-mails: marcelo. E-mails: ucordani usp. E-mail: camaramaurer gmail. The Iriri-Xingu domain, located in the central part of the Amazonian craton, consists of extensive occurrences of Paleoproterozoic volcanic rocks and granites with published ages of ca. Exposures of basement rocks are small and rare. These are the first records of high-grade metamorphism at ca. The Central Amazonian province of the Amazonian craton was originally defined by Cordani et al.

Their paper was the first in which the tectonic evolution of the Amazonian craton was considered by means of a mobilistic approach and was characterized as a stable area in relation to the Paleoproterozoic Maroni-Itacaiunas mobile belt to the northeast. The initial work of Cordani et al. Figure 1.

Historical Geology/U-Pb, Pb-Pb, and fission track dating

The mineral zircon adds three more fundamental advantages to uranium—lead dating. First, its crystal structure allows a small amount of tetravalent uranium to substitute for zirconium but excludes with great efficiency the incorporation of lead. It might be said that one begins with an empty box. Second, zircon, once formed, is highly resistant to change and has the highest blocking temperature ever observed.

Finally, with few predictable exceptions, zircon grows or regrows only in liquid rock or in solid rock reheated to approach its melting point.

U–Pb laser ablation ICP-MS zircon dating across the Ediacaran–Cambrian results [90–%]: two composite grains with cores (Zr 1 and Zr 27) yielding U–​Pb.

Human immunodeficiency virus type 1 HIV-1 sequences that pre-date the recognition of AIDS are critical to defining the time of origin and the timescale of virus evolution 1 , 2. Other historically documented sequences, important calibration points to convert evolutionary distance into time, are lacking, however; ZR59 is the only one sampled prior to Phylogenetic analyses position this viral sequence DRC60 closest to the ancestral node of subtype A excluding A2.

Relaxed molecular clock analyses incorporating DRC60 and ZR59 date the M group’s most recent common ancestor near the beginning of the 20 th century. The recovery of viral gene sequences from decades-old paraffin-embedded tissues opens the door to a detailed paleovirological investigation of the evolutionary history of HIV-1 that is not accessible by other methods.

Viral nucleic acids were extracted from this specimen using protocols optimized for the recovery of nucleic acids from ancient or degraded samples 3 , 4.

Detrital zircon geochronology

He specialized in research and development in zirconium products, and allegedly had distant ties to Iran. The other source of vector is the reaction between the zirconium and water. The zirconium alloy will react with water to produce hydrogen and oxide, but it also produces heat that has to be removed. A silicate of zirconium usually crystallized in the tetragonal system as simple four-sided prisms capped by four-sided pyramids.

In addition Davy anticipated the isolation of silicon, aluminium, and zirconium.

Geochemistry, U-Pb dating, and Lu-Hf isotopes of zircon and monazite of revealed that the three types of porphyritic rocks are enriched in HREE, Zr, Nb, Ga.

To verify if a specific tire is affected by this program, check the tire sidewall inscription. Only tires with their brand name, product line, tire size and DOT code identified in the exchange program scope are affected. The attached pictures provide samples of the relevant sidewall inscriptions. Tires from Continental. Tire Identification Tire identification – How you find out if your passenger car tire is affected.

The sample is a ContiSportContact 5 P in /35 ZR 19 (91Y) EXTRA LOAD tire with Important: The complete DOT serial number including production date is.

These phases are often found as accessory minerals in igneous rock and can yield robust information about the relative sequencing of a rock’s crystallization history. To assess these textural relationships, the cross-cutting relationships between the Zr-rich phases and their surroundings were analyzed and characterized with a combination of imaging and EDS techniques. Applying this relative dating method while anchored in an absolute time scale can bolster evidence for a particular crystallization history.

For example, U-Pb geochronology uses phases such as zircon and baddeleyite to establish the absolute age of a sample. Trace elements such as uranium U , hafnium Hf , and other rare Earth elements REEs will substitute for zirconium in these minerals, making them excellent targets for high precision U-Pb dating, among other geochronological methods. Mauricio Ibanez-Mejia aided in identifying areas of interest in the sample.

The claimant, a car dealer based in the Netherlands, bought a used car from the defendant, a German car dealer in April In August , the police seized the car from the claimant on the suspicion that the car had been stolen prior to the contract of sale. The insurance company of the original owner demanded the turnover of the car from the claimant in a letter dated May

He indicated that he was 52 years old, had a college education and was last employed as a construction worker, a job he left in September , following a workplace injury. On March 3, , the Tribunal asked the Applicant and his authorized representative to provide a copy of the reconsideration letter that was the subject of the appeal, allowing that, if the missing document was received by June 11, , the appeal would be considered to be on time.

In doing so, the General Division found that he lacked a reasonable explanation for the delay or a continuing intention to pursue his appeal. Above all, it found that the Applicant did not have an arguable case. In a decision dated December 2, , the Appeal Division refused leave after finding that none of the allegations of error directed against the General Division had a reasonable chance of success on appeal.

On December 6, , the Honourable Justice James Russell granted the application and ordered on consent that the matter be referred back to a different member of the Appeal Division for redetermination. I have decided that an oral hearing is unnecessary and that the appeal can proceed on the basis of the documentary record for the following reasons:.

The Appeal Division must either grant or refuse leave to appeal. Subsection 58 2 of the DESD A provides that leave to appeal is refused if the Appeal Division is satisfied that the appeal has no reasonable chance of success. It is an initial hurdle for the Applicant to meet, but it is lower than the one that must be met on the hearing of the appeal on the merits. At the leave stage, the Applicant does not have to prove the case.
