Moderate-large earthquakes usually trigger a large number of landslides. The prehistoric large landslides can be analyzed to determine the probability of its seismic origin, and further recognized as an indicator of fault activity and earthquake intensity. Based on field investigation, high-resolution satellite image interpretation and cosmogenic exposure dating of landslide deposit, the paper presents a large, long-runout Luanshibao rock avalanche the LSB rock avalanche , southeast Tibet. It suggests that the Maoya section of Litang fault is probably more dangerous than other sections due to the high density of large co-seismic landslides, which could present useful reference for the alignment selection of future Sichuan-Tibet railway.

Subscriber Account active since. Of all the rituals of love, the first date is perhaps the most paramount — and the most dreaded. Hundreds of questions surround the pivotal event: How do you secure a date? What will you do once you’ve got one? Will your date think you’re funny, or stupid? Like everything else, dating — the often perplexing , sometimes revealing labor of love — has evolved over the years.

Tip-dating and the origin of Telluraves.

Van Dooren, M. Salemi, A. Molecular-clock analysis was performed using the Tamura-Nei substitution model and gamma distributed rate heterogeneity based on the maximum-likelihood topology of the combined long-terminal-repeat and env third-codon-position sequences. Since the molecular clock was not rejected and no evidence for saturation was found, a constant rate of evolution at these positions for all 33 HTLV-I and STLV-I strains was reasonably assumed.

Interspecies transmissions, most probably simian to human, must have occurred around that time and probably continued later.

Dating the origin and dispersal of hepatitis B virus infection in humans and primates

The origin of hepatitis B virus HBV infection in humans and other primates remains largely unresolved. Understanding the origin of HBV is crucial because it provides a framework for studying the burden, and subsequently the evolution, of HBV pathogenicity with respect to changes in human population size and life expectancy. To investigate this controversy we examined the relationship between HBV phylogeny and genetic diversity of modern humans, investigated the timescale of global HBV dispersal, and tested the hypothesis of HBV-human co-divergence.

We find that the global distribution of HBV genotypes and subgenotypes are consistent with the major prehistoric modern human migrations. This coincides with the origin of modern non-African humans. Crucially, the most pronounced increase in the HBV pandemic correlates with the global population increase over the last 5, years.

Extensive dating analyses indicated that the origin of X. citri subsp. citri occurred more recently than the main phylogenetic splits of Citrus plants.

The figures are boldly embossed and decorated with carefully punched patterns. This sophisticated technique flourished in the centuries before the Birth of Christ among the Thracians, who lived in the area that is now Bulgaria and Romania. In style too the cauldron looks like Thracian silver work. However, several of the objects depicted are Celtic, such as the helmets and the Celtic war trumpet carnyx. It is most likely that the cauldron was made where Celtic and Thracian peoples lived close together, probably in southwest Romania or northwest Bulgaria.

We do not know how this magnificent piece of work reached Denmark. The riddles of the cauldron are yet to be completely solved. The Gundestrup Cauldron was probably produced in south-western Romania or north-western Bulgaria. Pitcher of gilded silver from Rogozen, north-western Bulgaria, c. The dear and the lion are shaped in the same fashion as some of the animals on the Gundestrup Cauldron. The carnyx, a Celtic wind instrument, is depicted on the Gundestrup Cauldron.

By Larry Getlen. But when these single women, stripped from their dependency on fathers and husbands, began to be courted in public, police, politicians, and civic leaders were alarmed. These circumstances gave birth to dating rituals and other unfortunate traditions that still remain — or, at least, still cause confusion as mores change — today. In , the average female worker earned less than half of what a man would earn in the same position. But as these women were courted in public, efforts were undertaken to curb what authorities viewed as a potential public menace.

She recalls the report of one such special agent, staked out at the Strand Hotel in Midtown, who noted that the women he was spying on did not seem like prostitutes, per se, but were concerning nonetheless. Rockefeller Jr. It sounds like a joke, until you learn that some women were thrown in jail for this horrible crime. They saw them as romantic.

Archeometry and archaeology: origin, dating and material technologies

U-Pb ages, trace element content and oxygen isotope ratios of single zircons from five plagiogranite intrusions of the Troodos ophiolite were measured in order to determine their crystallization age and assess the importance of fractional crystallization versus crustal anatexis in their petrogenesis. The results indicate that oceanic magmatism in Troodos took place at The new age inferred for seafloor spreading and ocean crust accretion in Troodos nearly overlaps that of the Semail ophiolite in Oman Ma , strengthening previous indications for simultaneous evolution of both ophiolites in similar tectonic settings.

The lower values in this range are lower than those expected in equilibrium with mantle-derived melt 5. The inferred high percentage of crustal component is consistent with the existence of a shallow axial magma chamber, typical of fast spreading MOR settings, within the Troodos slow-spreading ridge environment. This apparent contradiction may be reconciled by episodically intense magmatism within an otherwise slow, magmatically-deprived spreading axis.

Examined the association between witnessing interparental violence as a child, being a victim of parental physical violence, and perpetrating violence in dating.

It may also include a grandparent, other relative, or divorced parents who lived with you during part of your childhood. These people strongly influence who we become.

The rituals of courtship have evolved over time, and what is considered romantic today would have been scandalous, if not criminal, less than years ago. As revealed in Moira Weigel’s Labor of Love: The Invention of Dating , a remarkable history of the subject, here are 10 things you might not know about dating and courtship over the years. It was first used in a newspaper column in which a young man laments that his girlfriend is seeing other people—that they are “fillin’ all my dates,” as in “the dates on her calendar.

All of these methods measure the amount of radioactive decay of chemical elements; the decay occurs in a consistent manner, like a clock, over long periods of time.

In order for a radioactive parent-daughter pair to be useful for dating, many criteria must be met. This section examines these criteria and explores the ways in which the reliability of the ages measured can be assessed. Because geologic materials are diverse in their origin and chemical content and datable elements are unequally distributed, each method has its strengths and weaknesses. Of these, only the radioisotopes with extremely long half-lives remain.

It should be mentioned in passing that some of the radioisotopes present early in the history of the solar system and now completely extinct have been recorded in meteorites in the form of the elevated abundances of their daughter isotopes. Analysis of such meteorites makes it possible to estimate the time that elapsed between element creation and meteorite formation.

Natural elements that are still radioactive today produce daughter products at a very slow rate; hence, it is easy to date very old minerals but difficult to obtain the age of those formed in the recent geologic past. This follows from the fact that the amount of daughter isotopes present is so small that it is difficult to measure. The difficulty can be overcome to some degree by achieving lower background contamination, by improving instrument sensitivity, and by finding minerals with abundant parent isotopes.

Geologic events of the not-too-distant past are more easily dated by using recently formed radioisotopes with short half-lives that produce more daughter products per unit time.
