Deceit, as understood by us and as presented to the artists invited to participate on this album, was as much about fairy-tales and playful trickery as about fake news, lies and uncertainty. In the light of current events in the US and in Poland, our personal interpretation of this album unfortunately now rings closer to the latter topics. The prevalent hate speech, lies spread by national media, violation of human rights and outright crimes condoned by those in power — all of that makes the release of this mixtape much more bitter. Right now, Poland has the strictest abortion laws in the European Union and is looking to increase the restrictions. Furthermore, we highly encourage you to donate to various funds set up to help protesters in the US, the list can be found here: ujeb. We will not use this album description to elaborate on our stance on the issues of systemic racism nor will we say more about the artistic content of this album, because we really do not want to make it about ourselves as the situation both the US and in Europe is far more important than any music. However, we want it to be clear: we are all against cherry picking black culture as our scene would not exist without black music and we will be educating ourselves and our listeners about the roots of the culture that we all benefit from and are fortunate enough to be a part of. BAS stands with all those protesting against racism, oppression, violence, social inequality and police brutality. Time to put your money where your mouth is.

The science is in. Questions remain: If you are having sex with condoms do you need to disclose? If you decide to have sex without condoms what is required to ensure you are both safe? I oscillated between having HIV as part of my profile either openly or ambiguously , often attracting negative or patronising comments and some straight out blocking. If someone did tell me they were accepting of my status, I would ask them how the rest of their family might feel as I was openly living with HIV having chosen to educate to ensure no other woman received such a derailing diagnosis before settling down to have children.

This always changed their perspective and still does.

Studies of Cave Sediments pp Cite as. Carbonate speleothems that contain ppb-ppm levels of uranium can be dated by the U- U- Th and U- Pa disequilibrium techniques. Accurate ages are possible if the initial concentrations of Th and Pa are well constrained and if the system has remained closed to post-depositional exchange of uranium, thorium, and protactinium. For many speleothems, particularly those composed of nearly pure calcite, initial Th may be trivial.

Because Pa is more soluble than Th, Th is a poor analog for Pa. Therefore, initial Pa tends to be more significant than initial Th for young samples, although this problem becomes less significant or even insignificant with increasing age. Thermal ionization mass spectrometry TIMS and inductively coupled plasma mass spectrometry ICP-MS offer significant improvements in counting efficiency and sample throughput compared to traditional decay-counting techniques.

Materials as young as tens of years and older than , years are potentially dateable by the U- U- Th method. Unable to display preview. Download preview PDF. Skip to main content. This service is more advanced with JavaScript available. Advertisement Hide. Dorale R.

There are those of us living with HIV, who carry deep emotional scars of rejection in disclosing our status to potential partners. It was two years later that the concept gained traction in Australia. These anxieties include rejection, physical and emotional attack and our personal health information shared with others without our permission. Has it helped people living with HIV to find love, or an interlude of sexual pleasure? Timothy chose not to disclose to his family or friends and only his HIV doctor and nurses knew of his status.

We always used condoms as this is the norm in the gay community. Be confident in deciding when, if or how you disclose. Timothy says in the gay community, the newly diagnosed guys are often afraid that the only people they can date again are other positive guys.

The detailed analysis of silica indurations and silicified wood sheds new light on the potential applications and limitations of U-series and U-Pb geochronology of opal and chalcedony. U-series dating of Late Pleistocene opal from weathering profiles in the Yilgarn Craton Western Australia substantiate a climate control of silica precipitation rates.

U-Pb case studies on Miocene silica from the Siebengebirge Rhenish Massif and Lesvos Northeast Aegean confirm that hydrous silica is capable to record near-surface, low temperature hydrological events, such as periods of intensified weathering, or hydrothermal activity bound to fault systems. U-Pb systematics of silica allows for drawing inferences on the interplay between climate and denudation, as well as on the timing of major tectonic events that have not yet been accessible with any other geochronological method.

Despite reliable age information recorded in simple growth sequences, many silica samples bear evidence that properties had been altered since the initial silica deposition. Disturbance and secondary mobility is obvious for isotopic data with presence of unsupported radiogenic lead and excessively heterogeneous U-Pb ages. However, hazards to the U-Pb system might happen more hideous.

Partially open system behaviour may be encountered in silicified wood with high amounts of relict organic material.

New ages for flowstone, sediments and fossil bones from the Dinaledi Chamber are presented. We combined optically stimulated luminescence dating of sediments with U-Th and palaeomagnetic analyses of flowstones to establish that all sediments containing Homo naledi fossils can be allocated to a single stratigraphic entity sub-unit 3b , interpreted to be deposited between ka and ka. This result has been confirmed independently by dating three H.

We consider the maximum age scenario to more closely reflect conditions in the cave, and therefore, the true age of the fossils. By combining the US-ESR maximum age estimate obtained from the teeth, with the U-Th age for the oldest flowstone overlying Homo naledi fossils, we have constrained the depositional age of Homo naledi to a period between ka and ka. These age results demonstrate that a morphologically primitive hominin, Homo naledi, survived into the later parts of the Pleistocene in Africa, and indicate a much younger age for the Homo naledi fossils than have previously been hypothesized based on their morphology.

We dated cave deposits in the Sierra Nevada using U–Th dating of speleothems, paleomagnetic dating of fine sediment, and cosmogenic 26Al/10Be burial.

In Section 2. However, certain natural processes can disturb this equilibrium situation, such as chemical weathering, precipitation from a solution, re- crystallisation etc. The leads to two new types of chronometric systems: An intermediate daughter isotope in the decay series is separated from its parent nuclide incorporated into a rock or sediment, and decays according to its own half life.

A parent nuclide has separated itself from its previous decay products and it takes some time for secular equilibrium to be re-established. This idea is most frequently applied to the U-decay series, notably Th and U. The first type of disequilibrium dating forms the basis of the U- U and Th methods Sections 9.

Uranium-Thorium dating is based on the detection by mass spectrometry of both the parent U and daughter Th products of decay, through the emission of an alpha particle. The decay of Uranium to Thorium is part of the much longer decay series begining in U and ending in Pb. With time, Thorium accumulates in the sample through radiometric decay. The method assumes that the sample does not exchange Th or U with the environment i.

The method is used for samples that can retain Uranium and Thorium, such as carbonate sediments, bones and teeth. Ages between and , years have been reported. Augustinus, P. Journal of Quaternary Science Ayliffe, L.
